Abstract
Kaempferol (KPR), a flavonoid compound found in various plants and foods, has garnered attention for its anti-inflammatory, antioxidant, and anticancer properties. In preliminary studies, KPR can modulate several signaling pathways involved in inflammation, making it a candidate for treating cholecystitis. This study aimed to explore the effects and mechanisms of KPR on lipopolysaccharide (LPS)-induced human gallbladder epithelial cells (HGBECs). To assess the impact of KPR on HGBECs, the HGBECs were divided into control, KPR, LPS, LPS + KPR, and LPS + UDCA groups. Cell viability and cytotoxicity were evaluated by MTT assay and lactate dehydrogenase (LDH) assay, respectively, and concentrations of KPR (10-200 μM) were tested. LPS-induced inflammatory responses in HGBECs were to create an in vitro model of cholecystitis. The key inflammatory markers (IL-1β, IL-6, and TNF-α) levels were quantified using ELISA, The modulation of the MAPK/NF-κB signaling pathway was measured by western blot using specific antibodies against pathway components (p-IκBα, IκBα, p-p65, p65, p-JNK, JNK, p-ERK, ERK, p-p38, and p38). The cell viability and LDH levels in HGBECs were not significantly affected by 50 μM KPR, thus it was selected as the optimal KPR intervention concentration. KPR increased the viability of LPS-induced HGBECs. Additionally, KPR inhibited the inflammatory factors level (IL-1β, IL-6, and TNF-α) and protein expression (iNOS and COX-2) in LPS-induced HGBECs. Furthermore, KPR reversed LPS-induced elevation of p-IκBα/IκBα, p-p65/p65, p-JNK/JNK, p-ERK/ERK, and p-p38/p38 ratios. KPR attenuates the LPS-induced inflammatory response in HGBECs, possibly by inhibiting MAPK/NF-κB signaling.

Abstract
Minimal access breast surgery with the assistance of an endoscopy or robot has been an important advancement in surgical treatment in recent years. Compared to conventional open surgery, minimal access breast surgery only requires small incisions in concealed areas such as axillary fossa, avoiding visible scars on the surface of the breast, significantly improving the postoperative aesthetic appearance and patient satisfaction. With the rapid development of minimal access breast surgery, several institutions have established their own distinctive techniques. The concept of membrane anatomy in the breast, for example, has led to more natural-looking breast reconstruction following endoscopic procedures. The adoption of the reverse space dissection technique has greatly optimized the workflow of endoscopic breast cancer resection. Intraoperative navigation system for endoscopic breast-conserving surgery could allow precise localization of excision margins. Furthermore, the widespread use of the cold dissection technique for flap separation has reduced surgical duration and minimized flap damage. The emergence of unique techniques in the field of minimal access breast surgery promises to further advance and promote the adoption of minimal access breast surgery in China.

Abstract
Objective: To examine the postoperative prosthesis-related complications, short-term surgical outcomes and patient satisfaction with breast reconstruction between patients who underwent endoscopic assisted versus conventional nipple sparing mastectomy and immediate prothesis breast reconstruction. Methods: This study was a retrospective cohort study. A retrospective analysis was performed on clinical data of 104 women with breast cancer who received nipple sparing mastectomy and immediate prothesis breast reconstruction from August 2021 to August 2022 at the Breast Tumor Center, Sun Yat-Sen Memorial Hospital, Sun Yat-Sen University. They were divided into two groups according to the surgical approach. A total of 53 patients, aged (43.3±9.9) years (range: 25 to 66 years), underwent endoscopic nipple sparing mastectomy (E-NSM group) and immediate prothesis breast reconstruction. The other 51 patients aged (39.9±7.8) years (range: 25 to 54 years) underwent conventional open surgery (C-NSM group). Short-term surgical outcomes including operation time, postoperative hospital stay, postoperative blood loss, and postoperative drainage volume in 2 days were recorded. Patient satisfaction with breast reconstruction was compared using the Wilcoxon rank sum test. Postoperative prothesis-related complications were investigated to determine the experience to deal with them. Results: No postoperative prosthesis-related infection, prosthesis loss, or necrosis of the nipple-areola complex occurred in the E-NSM group, while 1 patient suffered from hematoma, whose wound was skinned with resuture after disinfection. Five patients in the C-NSM group had prosthesis-related infection, 2 of them received prosthesis removal surgery combined with sufficient antimicrobial agent, another one underwent surgery for subcutaneous placement of the drain, as well as antimicrobial agent therapy, and the rest of them healed up only with antimicrobial agent therapy. All recovered well after treatment. One patient recovered from necrosis of the nipple-areola complex through periodic iodophor disinfection and dressing which ended in improvement of necrotic areas, another patient who had hematoma accepted the same treatment mentioned above and also healed. All the patients mentioned above are now in stable conditions. Patients in the E-NSM group had higher satisfaction with the cosmetic results of the breast prosthesis implant than those in the C-NSM group (Z=-4.511, P<0.01). Conclusions: Both surgical approaches were proven to be safe and effective with a low rate of postoperative prosthesis-related complications. Patients in the E-NSM group were more satisfied with the cosmetic results of breast reconstruction than those in the C-NSM group.

Abstract
Objective: To investigate the clinical characteristics and maternal and fetal prognosis of pregnant women with acute fatty liver of pregnancy (AFLP). Methods: The clinical data of 86 AFLP pregnant women admitted to the Third Affiliated Hospital of Guangzhou Medical University from September 2017 to August 2022 were collected, and their general data, clinical characteristics, laboratory tests and maternal and fetal outcomes were retrospectively analyzed. Results: (1) General information: the age of the 86 pregnant women with AFLP was (30.8±5.4) years, and the body mass index was (21.0±2.5) kg/m2. There were 50 primiparas (58.1%, 50/86) and 36 multiparas (41.9%, 36/86). There were 64 singleton pregnancies (74.4%, 64/86) and 22 twin pregnancies (25.6%, 22/86). (2) Clinical characteristics: the main complaints of AFLP pregnant women were gastrointestinal symptoms, including epigastric pain (68.6%, 59/86), nausea (47.7%, 41/86), anorexia (46.5%, 40/86), vomiting (39.5%, 34/86). The main non-gastrointestinal symptoms were jaundice of skin and/or scleral (54.7%, 47/86), edema (38.4%, 33/86), fatigue (19.8%, 17/86), bleeding tendency (16.3%, 14/86), polydipsia or polyuria (14.0%, 12/86), skin itching (8.1%, 7/86), and 17.4% (15/86) AFLP pregnant women had no obvious symptoms. (3) Laboratory tests: the incidence of liver and kidney dysfunction and abnormal coagulation function in AFLP pregnant women was high, and the levels of blood ammonia, lactate dehydrogenase and lactic acid were increased, and the levels of hemoglobin, platelet and albumin decreased. However, only 24 cases (27.9%, 24/86) of AFLP pregnant women showed fatty liver by imageology examination. (4) Pregnancy outcomes: ① AFLP pregnant women had a high incidence of pregnancy complications, mainly including renal insufficiency (95.3%, 82/86), preterm birth (46.5%, 40/86), hypertensive disorders in pregnancy (30.2%, 26/86), gestational diabetes mellitus (36.0%, 31/86), fetal distress (24.4%, 21/86), pulmonary infection (23.3%, 20/86), disseminated intravascular coagulation (16.3%, 14/86), multiple organ dysfunction syndrome (16.3%, 14/86), hepatic encephalopathy (9.3%, 8/86), and intrauterine fetal death (2.3%, 2/86). ② Treatment and outcome of AFLP pregnant women: the intensive care unit transfer rate of AFLP pregnant women was 66.3% (57/86). 82 cases were improved and discharged after treatment, 2 cases were transferred to other hospitals for follow-up treatment, and 2 cases (2.3%, 2/86) died. ③ Neonatal outcomes: except for 2 cases of intrauterine death, a total of 106 neonates were delivered, including 39 cases (36.8%, 39/106) of neonatal asphyxia, 63 cases (59.4%, 63/106) of neonatal intensive care unit admission, and 3 cases (2.8%, 3/106) of neonatal death. Conclusions: AFLP is a severe obstetric complication, which is harmful to mother and fetus. In the process of clinical diagnosis and treatment, attention should be paid to the clinical manifestations and laboratory tests of pregnant women, early diagnosis and active treatment, so as to improve maternal and fetal outcomes.

Abstract
Objective: To investigate the efficacy of the first-day suspension method for improving the success rate of construction of nasopharyngeal carcinoma-patient derived organoids (NPC-PDO). Methods: The tumor samples of 14 nasopharyngeal carcinoma(NPC) patients, i.e.,13 males and 1 female, with a mean age of 43.0±12.0 years old, were collected from the Affiliated Tumor Hospital of Guangxi Medical University and the First Affiliated Hospital of Guangxi Medical University from January 2022 to July 2022. The tumor samples of 3 patients were digested into single cell suspension and divided into 2 groups, for comparing the efficacy of NPC-PDO construction by the direct inoculation method and the first-day suspension method. The remaining 11 patients were randomized to receive either the direct inoculation method or the first-day suspension method for NPC-PDO construction. The diameter and the number of spheres of NPC-PDO constructed by the two methods were compared by optical microscope; the 3D cell viability detection kit was used to compare the cell viability; the survival rates were compared by trypan blue staining; the success rates of the two construction methods were compared; the number of cases which could be successfully passaged for more than 5 generations and were consistent with the original tissue by pathological examination was counted; and the dynamic changes of cells in suspension overnight were observed by live cell workstation. The independent sample t-test was applied to compare the measurement data of the two groups, and the chi-square test was used to compare the classification data. Results: Compared with the direct inoculation, the diameter and the number of spheres of NPC-PDO constructed by the first-day suspension method were increased, with a higher cell activity, and the success rate of construction was obviously improved (80.0% vs 16.7%, χ2=4.41, P<0.05). In the suspension state, some of the cells aggregated and increased their ability to proliferate. Conclusion: The first-day suspension method can improve the success rate of NPC-PDO construction, especially for those whose original tumor sample size is small.

Abstract
Objective: To construct a diagnostic and predictive model for chronic obstructive pulmonary disease complicated with pulmonary hypertension (COPD-PH) and evaluate its effect. Methods: A total of 1 514 COPD patients treated in 5 hospitals from January 1, 2014 to December 31, 2019 were retrospectively collected and divided into training cohort (1 072 cases) and validation cohort (442 cases) according to the ratio of 7∶3 according to the inclusion time. Data including demographic data, smoking status, history of disease, and clinical examination were collected through patient medical records and electronic medical record systems. Multivariate logistic regression models were used to explore the related factors of COPD-PH, and the nomogram model was constructed using the "rms" program package. The calibration curve was used to evaluate the consistency between the prediction probability of the model and the actual results. The C index and the area under the receiver operating characteristic curve (ROC) were used to evaluate the discrimination of the model. The decision curve analysis (DCA) was used to evaluate the clinical practicability of the model. Results: In the training cohort, 3.7%, 15.2% and 81.1% were aged 50-59, 60-69 and ≥70 years, respectively, which were significantly different from the age composition of the validation cohort (7.9%, 27.8% and 64.3%, respectively) (P=0.041). There was no significant difference between the training cohort (79.4%) and the validation cohort (84.6%) (P=0.243). Multivariate logistic regression analysis of the training cohort showed that age ≥70 years [OR (95%CI): 3.32 (1.49-7.36)] and smoking status [former (current) smoking, OR (95%CI)] were 3.67 (2.51-5.37) and 2.04 (1.44-2.90), respectively], NT-probNP≥1 400 ng/L[OR (95%CI): 9.88 (6.23-15.66)], right atrial diameter [OR (95%CI): 1.11 (1.07-1.15)] was COPD-related factors of PH, based on the above factors-PH nomogram COPD model was set up and develop for online tools (https://ph-666.shinyapps.io/zhonghua-PH/). The calibrated C index (95%CI) of the training cohort and the validation cohort were 0.82 (0.77-0.87) and 0.77 (0.68-0.86), respectively. The calibration curve was close to the diagonal in both the training cohort and the validation cohort. The AUC (95%CI) of the nomogram model was 0.82 (0.80-0.85) in the training cohort and 0.77 (0.73-0.82) in the validation cohort. ROC curve showed that the optimal threshold in the training cohort was 0.60, and the sensitivity and specificity under this value were 0.74 and 0.78, respectively; the optimal threshold for the validation cohort was 0.70, and the sensitivity and specificity under this value were 0.76 and 0.65, respectively. DCA analysis showed that the nomogram model provided better net benefits than the all-variable selection and no-variable selection strategies with threshold probabilities greater than 15.0% and 13.0% in the training and validation cohorts, respectively. Conclusions: The nomogram model for the diagnosis and prediction of COPD-PH is simple and accurate, which has a good clinical application prospect.

Abstract
Objective: To analyze the characteristics of heart rate variability (HRV) in patients with vestibular migraine (VM) and to explore its possible mechanism. Methods: Forty-eight patients with VM [17 males and 31 females, age (36.2±9.2) years], 44 patients with migraine [15 males and 29 females, age (34.4±9.0) years], and 30 patients with health check-ups during the same period [12 males and 18 females, age (34.6±6.5) years old] were selected as study subjects. Ambulatory ECG monitoring was performed in all subjects, and the HRV characteristics of each group were analyzed from both daytime and nighttime time phases. Time domain parameters were analyzed: standard deviation of normal to normal (SDNN), root mean square of successive differences (RMSSD), and percentage of normal to normal intervals differing by more than 50 ms (pNN50). The parameters in the frequency domain were analyzed: high frequency power (HF), low frequency power (LF), and the ratio of low frequency to high frequency power (LF/HF). Statistical analysis of the data was performed using SPSS 26.0 software. Results: At night, RMSSD (F=6.694) and HF (F=9.434) were lower in the VM and migraine groups compared to the control group, while LF/HF (F=16.049) and LF (F=9.434) were elevated compared to the control group, with statistically significant differences (P<0.05 or P<0.01), while LF was significantly elevated in the VM group compared to the migraine group, with a statistically significant (P<0.05). On the daytime measurements, mainly LF was elevated in the vestibular migraine group compared with the control group, while RMSSD was decreased compared with the control group, with statistically significant differences (P<0.05). Conclusion: Autonomic dysfunction characterized by sympathetic hyperfunction and vagal hypofunction is present in VM patients and is more pronounced at night. In addition, the degree of autonomic dysfunction may be more pronounced in VM patients than in migraine patients.

Abstract
The knowledge of high-pressure behavior of LiH is significant for the validation of fundamental theoretical models and applications in thermonuclear materials and potential energy supplies. The compressibility of 7LiH under isentropic compression at high pressure was investigated experimentally and theoretically. The experimental technique for quasi-isentropic compression with low-density materials was developed using the magnetocumulative generator CJ-100 and x-ray flash radiography. The x-ray images and extracted interface of the sample target in dynamic flash radiography experiments were obtained. According to each interface size of the target both before and after compression, the compression ratio of 7LiH and reference material aluminum was obtained. The density of the reference and using its known isentropic curve provide the pressure in the reference. The pressure in 7LiH was deduced from the pressure in the reference and using the calculated gradient correction factor. The quasi-isentropic data point at 438 GPa was obtained experimentally. A semiempirical three-term complete equation of state was constructed and validated for 7LiH using the theory of Mie-Grüneisen-Debye with experimental data from the literature. The quasi-isentrope data point is reasonably consistent with the theoretical results. The quasi-isentropic experimental techniques and results broaden the existing research scope and are practical and helpful to further validate theoretical models in the future.

Abstract
Objective: To examine the efficacy and safety of endothelin receptor antagonists (ERA) combined with phosphodiesterase 5 inhibitors (PDE5i) in the treatment of pulmonary artery hypertension (PAH). Methods: Computer-based retrieval was performed on PubMed, Cochrane Library, CNKI, Wanfang, and VIP database (up to February 12th, 2021). Randomized controlled trials about endothelin receptor antagonists (ERAs) or PDE5i in patients with PAH were collected. The change of 6-minute walking distance (6MWD) in 12-16 weeks was used as primary outcome index. Case fatality rate, worsening clinical events, WHO functional class (FC) improvement, adverse events (AEs), serious adverse events (SAE) were the key secondary outcomes indicators. STATA 16.0 software was used for network meta-analysis, and the pooled estimates of odds ratios (ORs) or weighted mean differences (WMDs) and 95% confidence intervals (CIs) of the results were shown. To help explain ORs and WMDs, we used the surface under the cumulative ranking curve (SUCRA) to calculate the probability of each intervention. Results: We included 29 trials with 5 949 participants. In network meta-analysis, Bosentan combined with Sildenafil (WMD=53.93, 95%CI=6.19-101.66) had shown the greatest improvement in 6MWD compared with placebo, followed by Bosentan combined with Tadalafil (WMD=50.84, 95%CI=7.05-94.62), Ambrisentan combined with Tadalafil (WMD=46.67, 95%CI=15.88-77.45), Bosentan (WMD=29.44, 95%CI=5.86-53.02), Ambrisentan (WMD=23.90, 95%CI=0.31-47.48) and Macitentan (WMD=21.57, 95%CI=2.45-40.69). According to SUCRA, the effects of different intervention measures on improving 6MWD in patients with arterial pulmonary hypertension were as follows: Bosentan+Sildenafil (82.9%)>Bosentan+Tadalafil (78.4%)>Ambrisentan+Tadalafil (77.1%)>Bosentan (49.2%)>Sildenafil (48.5%)>Ambrisentan (40.3%)>Macitentan (37.3%)>Tadalafil (33.0%)>Placebo (3.3%). For the WHO functional class, Sildenafil (OR=2.90, 95%CI=1.04-8.08) was optimal compared with placebo, followed by Bosentan (OR=2.15, 95%CI=1.15-4.04), and there was no significant difference in the rest. For clinical worsening, Bosentan combined with Tadalafil (OR=0.08, 95%CI=0.01-0.49) performed best compared with placebo, followed by Bosentan (OR=0.20, 95%CI=0.11-0.38), Bosentan combined with Sildenafil (OR=0.21, 95%CI=0.09-0.46), Ambrisentan combined with Tadalafil (OR=0.27, 95%CI=0.15-0.50), Sildenafil (OR=0.33, 95%CI=0.17-0.66) and Tadalafil (OR=0.44, 95%CI=0.21-0.90). There was no statistical difference between all interventions and placebo in terms of the incidence of adverse events and serious adverse events. For case fatality rate, Ambrisentan (OR=0.28, 95%CI=0.11-0.74) was statistically superior to placebo and there was no statistics difference in the rest. Conclusions: The combination therapy of ERAs and PDE5i performed well in the short-term improvement of motor function. Furthermore, there was no significant difference with monotherapy in terms of safety. However, it is worth emphasizing that the choice of treatment should be based on the patient's individualized situation and the patient's requirements.

Abstract
Objective: To analyze the clinical value and predictive difference of serum Golgi protein 73 (GP73) and serum autophagy-related protein p62 levels in the short-term prognosis of patients with hepatitis B virus-related acute-on-chronic liver failure (ACLF). Methods: Clinical data of admitted cases to our hospital from October 2018 to April 2020 were retrospectively analyzed. Simultaneously, there were 32 cases with HBV-related ACLF in group A, 65 cases with hepatitis B virus-related cirrhosis in group B and C (Child-Pugh Class A, 34 cases as B group, and Child-Pugh B/C class, 31 cases as group C), and another 30 healthy subjects served as the control group (group D). The serum GP73 and p62 levels of the four selected groups were measured. ACLF group patients were followed up for 3 months to analyze the prognosis of the patients. The serum GP73 and p62 levels of patients who died and survived during hospitalization were compared. The data were analyzed by one-way analysis of variance, independent sample t-test, and Pearson's correlation analysis. Receiver operating characteristic curve (ROC) was used to analyze the predictive value of GP73 and p62 levels in surviving patients. Results: GP73 levels in the four groups A, B, C and D were (284.30 ± 70.55) ng/ml, (125.33 ± 20.57) ng/ml, (159.82 ± 31.20) ng/ml, and (45.46 ± 10.22) ng/ml, respectively. The p62 levels were (1.30 ± 0.35) ng/ml, (2.88 ± 0.58) ng/ml, (2.02 ± 0.545) ng/ml, and (4.68 ± 1.03) ng/ml, respectively. GP73 detection value was significantly higher in group A than the other three groups (P < 0.05). Group D had significantly lower value than the other three groups (P < 0.05), and group C had significantly higher value than group B (P < 0.05). The detection value of p62 in group A was significantly lower than the other three groups (P < 0.05). Group D had significantly higher value than the other three groups (P < 0.05), and group B had slightly higher value than group C, and the differences were statistically significant (P < 0.05). There was a negative correlation between GP73 and p62 (r = -0.695, P < 0.001). Survived patients GP73 level in the ACLF group was significantly lower than dead patients [(212.17 ± 22.47) ng/ml and (340.08 ± 32.91) ng/ml, t = 12.493, P < 0.05], and p62 level was significantly higher than dead patients [(1.46 ± 0.28) ng/ml and (1.18 ± 0.35) ng/ml, t = 2.445, P < 0.05]. According to the ROC curve analysis results, the area under the curve (AUC) of GP73 was 0.865, the AUC of p62 was 0.750, and the combined AUC of the both was 0.968. Conclusion: Both GP73 and p62 have a certain predictive value for the short-term prognosis of HBV-related ACLF patients, but the combination of the two indicators has a higher predictive value.

Abstract
In recent years, with the changes in living standards and dietary structure, the incidence of non-alcoholic fatty liver disease has been increasing year by year in China, and the incidence rate in the general population is as high as 29.81%. An increasingly epidemiological evidence suggests that non-alcoholic fatty liver disease has become one of the causes of increasing liver cirrhosis and liver cancer. However, its etiology and pathogenesis are complex and have not yet been fully elucidated. Therefore, establishing an appropriate non-alcoholic fatty liver disease animal models for pre-clinical research is essential to elucidate its pathogenesis. This article summarizes the latest research progress of non-alcoholic fatty liver disease animal models, which are common at home and abroad in recent years.

Abstract
We report on a precision energy loss measurement and theoretical investigation of 100 keV/u helium ions in a hydrogen-discharge plasma. Collision processes of helium ions with protons, free electrons, and hydrogen atoms are ideally suited for benchmarking plasma stopping-power models. Energy loss results of our experiments are significantly higher than the predictions of traditional effective charge models. We obtained good agreement with our data by solving rate equations, where in addition to the ground state, also excited electronic configurations were considered for the projectile ions. Hence, we demonstrate that excited projectile states, resulting from collisions, leading to capture-, ionization-, and radiative-decay processes, play an important role in the stopping process in plasma.

Abstract
Objective: To study the value of chromosome microarray analysis (CMA) application in children with developmental delay (DD), intellectual disability (ID), autistic spectrum disorder (ASD) and multiple congenital anomalies (MCA). Methods: Genomic DNA was extracted from peripheral blood samples. Array-based comparative genomic hybridization (array-CGH) analysis and single nucleotide polymorphism array (SNP-array) were performed in 1 320 children with DD/ID, ASD, with or without epilepsy and MCA who were admitted to Peking University First Hospital from 2014 to 2019. The results of genetic etiology test of CMA in children with mental retardation or global DD was summarized. Results: Of 1 320 samples, there were 10 cases of aneuploid abnormality, 6 cases of uniparental disomy and one case of mosaicism, respectively. Pathogenic copy number variations (CNVs) were found in 320 cases and pathogenic CNVs were detected in 23 cases, with a combined detection rate of 26% (343/1 320). CNVs of uncertain clinical significance occurred in 107 cases, accounting for 8.1% (107/1 320). There were 25 cases of possible benign CNVs, accounting for 2% (25/1 320), while benign CNVs were reported in 20 cases, accounting for 1.5% (20/1 320). The detection rate of MCA with DD/ID was 39.8% (130/327). Conclusions: CMA has the advantages of high resolution and covering the whole genome. It can detect the chromosomal abnormalities, microdeletions and duplications seen under the microscope, thus the genetic etiology of children with mental retardation or global DD can be diagnosed.

Abstract
Objective: To verify the value of whole genomic copy number variation (WGCNV) detection and scoring system in the diagnosis and prognosis of lung adenocarcinoma. Methods: Seventy-six lung adenocarcinoma specimens including ninety-one tumor samples and twenty adjacent non-tumor lung tissue samples were collected using Laser capture microdissection (LCM). Whole genomic amplification (WGA) was used to enrich DNA and construct a sequencing library for next generation sequencing (NGS). Changes of larger than 5Mb CNV in this study were analyzed and scored. The nuclear grading and score of tumor cells in the surgery and pleural effusion cytology of lung adenocarcinoma specimens were evaluated separately. For each case, we evaluated (1) nuclear size, (2) mitotic counts, (3) nuclear atypia, (4) atypical mitoses. The data of disease-free survive (DFS) and overall survive (OS) were collected for assessing the prognostic value of WGCNV score. Meanwhile, receiver operating characteristic (ROC) and area under curve (AUC) were used to define a cut-off value and evaluate the diagnostic significance in lung adenocarcinoma. Results: The WGCNV scores of twenty adjacent non-tumor lung tissue samples were treated as normal control and all of WGCNV scores of tumor samples range from 0 to 9.95, the median score was 2.7. The WGCNV scores were divided into three groups: low score group <1.74, medium score grade 1.74~4.23, high score grade >4.23. The WGCNV score was positively associated with the nuclear grade scoring (r=0.780 90, P<0.001). The result for evaluation of prognostic value of the WGCNV scores showed that comparing with low WGCNV score group, Hazard Ratio (HR) of medium score group was 4.11 (95%CI=0.72~23.57) and high score group was 2.07 (95%CI=0.30~14.12). These results suggested that the risks of the medium and high WGCNV score group elevated. According to the analysis results of ROC curve, when the cut off value was 0.01, the sensitivity and specificity for lung adenocarcinoma diagnosis were 97.8% and 95.0% respectively, the positive predictive value (PPV) and negative predictive value (NPV) were 99.0% and 90.1%, respectively, the AUC was 0.981. In the differentiation of adenocarcinoma in situ (AIS) and minimally invasive adenocarcinoma (MIA) group and invasive adenocarcinoma group, when the cut off value was 1.8, the sensitivity and specificity between the two groups were 78.1% and 94.4%, and the PPV and NPV were 98.0% and 52.0%, respectively, the AUC was 0.896. Conclusion: This study verifies that WGCNV scoring system has a potential diagnostic and prognostic value in lung adenocarcinoma.

Abstract
In November 4, 2016, a 1 year and 3 months old male patient with face and neck scald complicated with severe scald of oropharynx was admitted to Guangzhou Red Cross Hospital 1 hour after injury. The child developed upper respiratory tract obstruction 2 hours after injury, therefore tracheotomy and intubation were performed immediately to establish an artificial airway, and symptomatic treatments such as anti-infection, fluid replacement, and dressing change were conducted. On the 10th day after injury, the child had difficult breathing during the test tube blocking before extubation, and it was difficult to extubate. Symptomatic treatments such as ventilator assisted ventilation and strengthened anti-infection were continued. On the 17th day after injury, extubation plan was adjusted. Thirty minutes before extubation, phenobarbital was injected intramuscularly for sedation, and atropine was used to reduce airway secretions, after which extubation was successful. After 21 days of treatment, the child was cured and discharged. In the treatment of this case, high attention was paid to the important influence of children's mental factors among causes of difficult extubation, which provided a reference for clinical treatment of extubation in children with tracheal tube after tracheotomy.

Abstract
Objective: To investigate the role of human papillomavirus (HPV) 16 early genes E2 and E6 and heterogeneous nuclear ribonucleoprotein (hnRNP) E2 and their interaction effects in the progression of the cervical cancer. Methods: Women with normal cervix (NC), low cervical intraepithelial neoplasia (CIN Ⅰ) and high cervical intraepithelial neoplasia (CIN Ⅱ/Ⅲ) from the cervical lesions cohort in Jiexiu County of Shanxi Province from June 2014 to September 2014, and patients with cervical squamous cell carcinoma (SCC) treated at the Second Hospital of Shanxi Medical University in the same period were enrolled in this study. There were 257 participants, about 67 NC cases (26.07%), 69 CIN Ⅰ cases (26.85%), 68 CIN Ⅱ/Ⅲ cases (26.46%), and 53 SCC cases (20.62%), respectively. The information of demographic characteristics, life health habits and cervical lesions were collected by using the structured questionnaire. Cervical exfoliated cells and cervical biopsy tissues were collected to detect the infection of HPV16 and the protein expression levels of hnRNP E2, HPV16 E2 and E6. According to the median-value of the protein expression levels of hnRNP E2, HPV16 E2 and E6 and E2/E6 ratio in the NC group, the study participants were divided into the high and low expression groups/ratio groups. The multivariate logistic regression model was used to analyze the correlation between HPV16 early gene E2 and E6, hnRNP E2 and cervical cancer. The interaction effect was analyzed by using the generalized multifactor dimensionality reduction (GMDR) model. Results: The ages of NC, CIN Ⅰ, CIN Ⅱ/Ⅲ and SCC groups were (47.00±9.07), (47.64±7.35), (46.37±8.67) and (51.26±8.03) years old, respectively. The multivariate logistic regression model analysis showed that the HPV16 E2 low expression, E6 high expression and E2/E6 low ratio could increase the risk of CIN Ⅱ/Ⅲ, about OR (95%CI) values 11.11 (1.63-75.56), 8.00 (1.28-50.04), and 9.75 (1.22-77.72), respectively and SCC, about OR (95%CI) values 14.22 (2.11-95.88), 10.33 (1.67-64.00), and 12.38 (1.56-97.91), respectively. The hnRNP E2 low expression could increase the risk of CIN Ⅱ/Ⅲ and SCC, about OR (95%CI) values 3.35 (1.39-8.10) and 5.53 (1.54-19.88). The result of GMDR showed that there were interaction effects of the hnRNP E2 low expression, HPV16 E2 low expression and HPV16 E6 high expression in both CIN Ⅱ/Ⅲ and SCC groups. Conclusion: The HPV16 E2 low expression, HPV16 E6 high expression and hnRNP E2 low expression could increase the risk of high-grade cervical intraepithelial neoplasia and cervical cancer, and they might have an important interaction effect in the progression of the cervical cancer.

Abstract
OBJECTIVE To evaluate the diagnostic accuracy of multiparametric MRI (mpMRI) for detecting extracapsular extension (ECE) in patients with prostate cancer (PCa). METHODS AND MATERIALS We searched MEDLINE, PubMed, Embase and the Cochrane library up to December 2018. We included studies that used mpMRI to differentiate ECE from organ-confined PCa with a combination of T2 weighted imaging (T2WI), diffusion-weighted imaging, and dynamic contrast-enhanced MRI. All studies included had pathological diagnosis with radical prostatectomy. Two reviewers independently assessed the methodological quality of included studies by using Quality Assessment of Diagnostic Accuracy Studies 2 tool. We calculated pooled sensitivity, specificity, positive and negative predictive values, diagnostic odds ratios and receiver operating characteristic curve for mpMRI from 2 × 2 tables. RESULTS A total of 17 studies that comprised 3374 participants were included. The pooled data showed a sensitivity of 0.55 (95% confidence interval 0.43, 0.66]) and specificity of 0.87 (95% confidence interval 0.82, 0.91) for extracapsular extension detection in PCa. CONCLUSION First, our meta-analysis shows moderate sensitivity and high specificity for mpMRI to differentiate ECE from organ-confined prostate cancer before surgery. Second, our meta-analysis shows that mpMRI had no significant differences in performance compared with the former meta-analysis with use of T2WI alone or with additional functional MRI. ADVANCES IN KNOWLEDGE It is the first meta-analysis to evaluate the accuracy of mpMRI in combination of TWI, diffusion-weightedimaging and dynamiccontrast-enhanced-MRI for extracapsular extension detection.

Abstract
Coherence distillation is one of the central problems in the resource theory of coherence. In this Letter, we complete the deterministic distillation of quantum coherence for a finite number of coherent states under strictly incoherent operations. Specifically, we find the necessary and sufficient condition for the transformation from a mixed coherent state into a pure state via strictly incoherent operations, which recovers a connection between the resource theory of coherence and the algebraic theory of majorization lattice. With the help of this condition, we present the deterministic coherence distillation scheme and derive the maximum number of maximally coherent states obtained via this scheme.

Abstract
Although brain-derived neurotrophic factor (BDNF) induces the differentiation of induced pluripotent stem cells (iPSCs) into neural stem cells (NSCs), its exact mechanism remains unelucidated. Wnt/β-catenin and ERK5 are two important signalling pathways of the Wnt and MAPK signalling cascades and are speculated to be closely related to the differentiation of cells. In this study, we reported the role of the Wnt/β-catenin and ERK5 signalling pathways on the BDNF-induced differentiation of iPSCs into NSCs. We examined the expression of β-catenin and p-ERK5 using small interfering RNA (siRNA)-induced silencing of β-catenin and ERK genes. We found that BDNF significantly improved the efficiency of iPSC differentiation and that the expression of β-catenin and p-ERK5 in the BDNF culture medium was significantly upregulated. Furthermore, we found that the expression of the β-catenin component was downregulated by siRNA-β-catenin, and the expression of the p-ERK5 component was downregulated by siRNA-ERK5. Flow cytometry showed that the differentiation rate of iPSCs was also significantly decreased by RNA interference. The results suggested that the Wnt/β-catenin and ERK5 signalling pathways are activated in the process of BDNF-induced iPSC differentiation. Interestingly, our study showed that siRNA-ERK5 not only inhibits the activity of the ERK5 signalling pathway but also partially controls the activity of the Wnt/β-catenin signalling pathway. The results suggested that the Wnt/β-catenin and ERK5 signalling pathways are not independently involved in the process of BDNF-induced iPSC differentiation. Our study showed that BDNF promotes the differentiation of iPSCs into NSCs by activating the Wnt/β-catenin and ERK5 signalling pathways, and an interconnected relationship may exist between the Wnt/β-catenin and ERK5 signalling pathways.

Abstract
Cancer-associated fibroblasts (CAFs), major components of the tumor microenvironment (TME), promote tumor growth and metastasis and inhibit the anti-tumor immune response. We previously constructed a DNA vaccine expressing human FAPα, which is highly expressed by CAFs, to target these cells in the TME, and observed limited anti-tumor effects in the 4T1 breast cancer model. When the treatment time was delayed until tumor nodes formed, the anti-tumor effect of the vaccine completely disappeared. In this study, to improve the safety and efficacy, we constructed a new FAPα-targeted vaccine containing only the extracellular domain of human FAPα with a tissue plasminogen activator signal sequence for enhanced antigen secretion and immunogenicity. The number of CAFs was more effectively reduced by CD8+ T cells induced by the new vaccine. This resulted in decreases in CCL2 and CXCL12 expression, leading to a significant decrease in the ratio of myeloid-derived suppressor cells in the TME. Moreover, when mice were treated after the establishment of tumors, the vaccine could still delay tumor growth. To facilitate the future application of the vaccine in clinical trials, we further optimized the gene codons and reduced the homology between the vaccine and the original sequence, which may be convenient for evaluating the vaccine distribution in the human body. These results indicated that the new FAPα-targeted vaccine expressing an optimized secreted human FAPα induced enhanced anti-tumor activity by reducing the number of FAPα+ CAFs and enhancing the recruitment of effector T cells in the 4T1 tumor model mice.

Abstract
Objective: To analyze the causes of complication of early acute kidney injury (AKI) in four severely burned patients, and to explore the related treatment methods. Methods: The clinical data of 4 patients with severe burn complicated with early AKI admitted to Guangzhou Red Cross Hospital Affiliated to Medical College of Jinan University (hereinafter referred to as our hospital) from June 2014 to December 2017 were retrospectively analyzed. All the patients were male, aged 23-33 (30±5) years old, with depth of burns ranged from deep partial-thickness to full-thickness, complicated with myofascial compartment syndrome of extremities and varying degrees of striated muscle injury, and treated in other hospitals before transfer to our hospital. The patients were numbered from small to large according to the total burn area. The total burn area of patients No. 1, 2, 3, and 4 was 10%, 80%, 90%, and 95% total body surface area respectively, their occurrence time of early AKI was 48, 11, 29, and 48 hours after injury respectively, and their time of arriving our hospital was 60, 11, 29, and 144 hours after injury respectively. Hypovolemic shock occurred in patients No. 2 and 3 at admission to our hospital. All the patients received continuous renal replacement therapy (CRRT) after admission to our hospital. Under the support of hemodynamic monitoring and organ function monitoring, the limbs complicated with myofascial compartment syndrome were incised, thorough decompression exploration was performed, and necrotic muscle tissue was removed or amputation was performed. After escharectomy and decompression of limbs, fresh granulation wounds were formed by temporarily covering wounds with Jieya dressing skin or pig skin, multiple debridements, and vacuum sealing drainage. Fresh granulation wounds and other wounds underwent staged eschar excision and shaving were covered with autologous Meek skin graft, particulate skin graft, reticular skin graft and small skin graft respectively. The treatment outcome, CRRT time, operation times, time of recovery of serum creatinine and myoglobin, length of hospital stay, and follow-up were recorded. Results: All the 4 patients were cured after transfer to our hospital. Among them, totally 5 limbs of patients No. 1 and No. 4 underwent amputation because of complication of myofascial compartment syndrome and a large amount of necrotic muscle which could not be preserved. Patients No. 1, 2, 3, and 4 were treated with CRRT for 19, 35, 14, and 25 days respectively and performed with operation for 5, 6, 10, 8 times respectively. Serum creatinine of patients No. 1, 2, 3, and 4 returned to normal on 22, 35, 37, and 48 days after transfer respectively, and their serum myoglobin returned to normal on 18, 28, 25, and 30 days after transfer respectively. Patients No. 1, 2, 3, and 4 were hospitalized for 52, 105, 148, and 156 days and discharged after basic wound healing. Follow-up for 1 to 36 months showed no abnormal renal function in 4 patients. Conclusions: The early AKI in patients No. 1 and 4 was caused by rhabdomyolysis after severe burn complicated with myofascial compartment syndrome, while that of the other 2 cases were also related to hypovolemic shock and poor renal perfusion. The success rate of early AKI treatment in severely burned patients can be effectively improved by removing the causes of diseases at the same time of CRRT and actively treating burn wounds under the support of organ function and hemodynamic monitoring.

Abstract
Objective: To explore the effect of Src on cervical cancer cells through ERK signal transduction pathway. Methods: Experimental study was carried out in vitro. Cervical cancer cell lines Hela (HPV-positive) and C33A (HPV-negative) were treated with Src kinase inhibitor PP2. Then, the cell cycle and apoptosis of each group were evaluated by using flow cytometry (FCM). Western blotting and Real-time PCR were used to detect the levels of the expression of ERK 1/2, c-Fos and c-Jun mRNA and protein respectively. The database was established and analyzed with SPSS statistical software (version 20.0). Results: After down-regulating Src, the cell proliferation was inhibited and cell apoptosis was induced. The proportions of G0/G1 stage of Hela and C33A cell in cell cycle increased while G2/M and S stages decreased. Meanwhile, the mRNA levels of ERK 1, ERK 2, c-Fos and c-Jun increased. And the expression levels of ERK 1/2, phosphorylated ERK 1/2 (p-ERK 1/2) and phosphorylated c-Fos (p-c-Fos) protein decreased, while c-Jun and phosphorylated c-Jun (p-c-Jun) protein expression increased. In addtion, the change level of Hela cell, p-ERK 1/2 and c-Fos protein were lower than that of C33A cell before and after the Src inhibition. Conclusions: Src, involved in regulating the expression of key factors of the ERK signal transduction pathway including p-ERK 1/2 and p-c-Fos, might be capable of promoting the proliferation of cervical cancer cells and inhibiting their apoptosis. The infection with HPV might have adjustable effect on this process.

Abstract
Objective: To understand the survival of HIV/AIDS patients after receiving antiretroviral therapy for 10 year in Henan province and related factors. Methods: The database of national integrated management system of HIV/AIDS was used to collect the basic information and follow-up information of HIV/AIDS patients who received antiretroviral therapy between 2003 and 2005 in Henan province. Software SPSS 23.0 was used to analyze the patients' survival and related factors based on the life-table method and Cox proportional hazards model. Results: Among the 2 448 HIV/AIDS patients who started antiretroviral therapy during 2003-2005, the men accounted for 53.5%, and women accounted for 46.5%. Up to 70.1% of the patients were aged 40-59 years and 95.5% of the patients had blood borne infections. The patients were observed for 10 years after antiviral treatment, and 719 cases died from AIDS related diseases, with a mortality rate of 3.78/100 per year (719/19 010 per year). The cumulative survival rates of patients within 1-year, 3 years, 5 years and 10 years were 0.94, 0.86, 0.78, 0.69 respectively. Compared with the patients aged <40 years, the HRs of the patients aged 40-, 50-, 60- and ≥70 years were 1.417 (95%CI: 0.903-2.222), 1.834 (95%CI: 1.174-2.866), 2.422 (95%CI: 1.539-3.810) and 3.424 (95%CI: 2.053-5.709) respectively. Compared with patients with baseline CD(4+)T lymphocyte >350 unit/ul, the HRs of the patients with CD(4+)T lymphocyte <50 unit/μl, 50-199 unit/ul and 200-350 unit/ul were 7.105 (95%CI: 5.449-9.264), 4.175 (95%CI: 3.249-5.366) and 2.214 (95%CI: 1.691-2.900) respectively. Compared with the women, the HR of the men was 1.480 (95%CI: 1.273-1.172). Compared with the patients who received second line ART therapy, the HR of patients receiving no second line therapy was 11.923 (95%CI: 9.410-15.104). Conclusions: The cumulative survival rate the HIV/AIDS patients after 10 years of antiretroviral therapy reached 0.69 in Henan. Male, old age, low basic CD(4+)T lymphocyte count and receiving no second line therapy were the risk factors for long-term survival of AIDS patients.

Abstract
Objective: To explore the effect of vaginal micro-environment alterations and HPV16 infection and their interaction in the progression of cervical intraepithelial neoplasia. Methods: The participants of this study came from the cervical lesions study cohort in Shanxi province, including 623 women with normal cervical (NC), 303 patients with pathogenically diagnosed low-grade cervical intraepithelial neoplasia (CINⅠ) and 93 patients with pathogenically diagnosed high-grade cervical intraepithelial neoplasia (CINⅡ/Ⅲ). The data of the demographic characteristics of the study subjects and factors related to cervical intraepithelial neoplasia were collected, and HPV16 infection were detected by using flow-through hybridization technology and H(2)O(2), β-glucuronidase, clotting enzyme, neuraminidase and leucocyte esterase in vaginal secretions were detected by using the combined detection kit of aerobic vaginitis and bacterial vaginosis. pH value and vaginal cleanliness were also detected at the same time. The database was established and analyzed by SPSS statistical software (version 22.0). Results: The HPV16 infection rate (trend χ(2)=55.45, P<0.001) and the abnormal rates of H(2)O(2) (trend χ(2)=26.19, P<0.001), pH (trend χ(2)=5.06, P=0.024), vaginal cleanliness (trend χ(2)=19.55, P<0.001), β-glucuronidase (trend χ(2)=17.52, P<0.001) and neuraminidase (trend χ(2)=14.90, P<0.001) increased gradually along with the severity of cervical intraepithelial neoplasia, but the abnormal rates of clotting enzyme and leucocyte esterase showed no same trend. The results of GMDR model analysis showed that there was interaction between HPV16 infection and abnormalities of H(2)O(2), β-glucuronidase, clotting enzyme and neuraminidase in CINⅠ group, and the interaction between HPV16 infection and the abnormalities of vaginal cleanliness, H(2)O(2), β-glucuronidase and neuraminidase in CIN Ⅱ/Ⅲ group. Conclusion: Our findings indicated that the vaginal micro-environment alterations and HPV16 infection could increase the risk of cervical intraepithelial neoplasia, and they might have an important synergistic effect in the progression of cervical intraepithelial neoplasia.

Abstract
Objective: To evaluate the clinical utility of the NoSAS score in the screening of patients with obstructive sleep apnea-hypopnea syndrome(OSAHS), and to compare the performance of the NoSAS score with other tools including Epworth Sleepiness Scale(ESS), STOP, STOP-Bang(SBQ) and Berlin questionnaires. Methods: A total of 444 consecutive patients(328 males and 116 females) with suspected OSAHS who underwent an overnight polysomnography(PSG) were recruited into this study. Five questionnaires including the NoSAS score, ESS, STOP, SBQ and Berlin were completed. Based on the severity of OSAHS which was determined by apnea-hypopnea index(AHI), the patients were classified into 4 groups: normal(<5 events/h), mild(5-15 events/h), moderate(15-30 events/h) and, severe (≥30 events/h) OSA.Sensitivity, specificity, positive predictive values, negative predictive values and the area under the receiver operating characteristics curve of 5 questionnaires were calculated. Results: With AHI≥5 events/h as the standard diagnosis of OSAHS, the NoSAS score and SBQ questionnaire showed a moderate performance, with the NoSAS score having the largest area under the ROC curve(0.753, P<0.001), followed by the SBQ questionnaire (0.727, P<0.001). The performance of the ESS, Berlin, and the STOP questionnaire was not high. Using mild moderate-severe(≥5 events/h), moderate-severe(≥15 events/h), and severe(≥30 events/h)OSAHS as cutoffs, NoSAS had the highest specificity and positive predictive values(80.2% and 88%, 72% and 69.8%, 66.3% and 50.5%), and the sensitivity and negative predictive values were (51.5% and 36.9%, 56.5% and 59.1%, 66.3% and 74.2%) .SBQ had the highest sensitivity and the negative predictive values(80.2% and 88%, 72% and 69.8%, 66.3% and 50.5%), and the specific and positive predictive values were (45.7% and 81.0%, 39.1% and 61.9%, 34.8% and 44.4%). The NoSAS score ≥ 7 had higher sensitivity and negative predictive value(75.0% and 47.1%, 78.1% and 66.5%, 82.7% and 81.9%)than the NoSAS socre ≥ 8. With AHI≥5 events/h as the standard diagnosis of OSAHS, the NoSAS score and the SBQ questionnaire had a higher accuracy than the other 3 questionnaires as screening questionnaires for diagnosing OSAHS, and the value of DOR were 4.298 and 3.758 respectively. Conclusions: The NoSAS score and the SBQ questionnaire have a moderate performance in diagnosing OSAHS. The NoSAS score is a new screening tool, and it is similar to the SBQ questionnaire, being also simple and effective. While the SBQ questionnaire is more widely used, it is necessary to further evaluate the diagnostic value of NoSAS score.

Abstract
Objective: To investigate the correlation of peripheral venous oxygen saturation (SpvO(2)) with mixed venous oxygen saturation (SvO(2)), pulmonary vascular resistance (PVR) and cardiac index (CI) in patients with pulmonary hypertension (PH), in order to predict these parameters using SpvO(2) and assess the prognosis of patients. Methods: Hospitalized patients diagnosed with PH by right heart catheterization in the Guangzhou Institute of Respiratory Diseases from July 2015 to October 2016 were retrospectively analyzed. Parameters during the right heart catheterization, including SvO(2,)SpvO(2,)cardiac output (CO) and mean pulmonary arterial pressure (mPAP) were recorded, while CI, PVR and other parameters were indirectly calculated. The correlation between SpvO(2) and SvO(2,)CO, CI, mPAP, PVR and other parameters were respectively analyzed and compared between groups. Results: A total of 77 PH patients were selected, which comprised of 39 males and 38 females. The results revealed that SpvO(2) was correlated positively with SvO(2,)CI and PaO(2) (P<0.05), but negatively with PVR, total pulmonary resistance (TPR), systemic vascular resistance, right atrial diameter and right ventricular diameter (P<0.05). In the group with SpvO(2) <65%, the dilation of the right atrium and right ventricle was more significant, the WHO heart function grade was worse, CI, systemic systolic pressure and mean systemic pressure were lower, and PVR and TPR were higher, as compared to those in the group with SpvO(2) ≥65%. (P<0.05). Conclusions: There was good consistency between SpvO(2) and SvO(2). Furthermore, SpvO(2) could indirectly reflect the CI, PVR and changes in right heart structure of PH patients, providing reference for the clinical prediction of CI and PVR, as well as the prognosis of PH patients, through the use of SpvO(2). Low SpvO(2) indicated a severe condition and poor prognosis.

Abstract
Objective: To investigate the effect of heterogeneous nuclear ribonucleoprotein K (hnRNP K) and its interaction with human papillomavirus 16 (HPV16) on cervical intraepithelial neoplasia (CIN). Methods: The participants included 67 women with normal cervix (NC), 69 women with CINⅠ and 68 women with CINⅡ/Ⅲ in a community cohort of pathologically diagnosed women established in Jiexiu of Shanxi province, from June 2014 to June 2015. A structured questionnaire was used to collect the demographic data of the subjects and the related factors of cervical lesions. Cervical exfoliated cells and cervical tissues from biopsy or surgery were selected. The infection status of HPV16 was detected by flow-through hybridization. The protein expression levels of hnRNP K were evaluated by Western blot. SPSS 23.0 software was used to collate and analyze the data. To study the differences in demographic characteristics, related factors, hnRNP K protein and HPV16 infection among NC, CINⅠand CINⅡ/Ⅲgroups, χ(2) test, trend χ(2) test, and Kruskal-Wallis H test were conducted. Multiple comparisons of hnRNP K protein in three groups were completed by using the Bonferroni method. The OR and its 95%CI of hnRNP K, HPV16 and CIN were calculated by using the unconditional logistic regression models. Two-way interactions between hnRNP K protein and HPV16 infection on CIN were analyzed by using additive model and related indicators. Results: HPV16 infection rates were 10.4% in women with normal cervix, 14.5% in women with CINⅠ and 41.2% in women with CINⅡ/Ⅲ, respectively. The differences among three groups were significant (P<0.001). Moreover, the infection rates of HPV16 gradually increased with the increasing severity of CIN (trend χ(2)=18.512, P<0.001). The differences in protein expression of hnRNP K among three groups were significant (H=48.138, P<0.001) and the expressionincreased with the development of cervical lesionss (trend χ(2)=21.765, P<0.001). Results from the interaction analysis indicated that there were additive effects between high expression of hnRNP K protein and HPV16 in CINⅡ/Ⅲ group compared with normal group (API=0.639, 95%CI: 0.083-1.196). In contrast, no such additive effect was found in CINⅠ group. Conclusions: HPV16 infection and over-expression of hnRNP K protein were associated with the increased risk of cervical intraepithelial neoplasia. There might be interaction between hnRNP K protein overexpression and HPV16 infection existed on the progress of CINⅡ/Ⅲ.

Abstract
PURPOSE To establish a predictive model for surgical resection of invasive pulmonary adenocarcinoma (IPA) presenting as ground-glass nodules (GGNs) based on a radiomics nomogram. METHODS The CT images of 239 patients with GGNs were collected, of which 160 cases were included in the training set to construct the predictive model and 79 cases were included in the validation set to verify the established predictive model. The least absolute shrinkage and selection operator algorithm was used to select the radiomic features and construct the radiomics tagging. The predictive model for the surgical resection of IPA was constructed using the radiomics nomogram. RESULTS The presence of IPA showed significant correlations with seven radiomics features (P < .01), which were the independent predictors. The predictive model constructed using the radiomics features performed well on the training set (area under the curve [AUC] 0.792, 95% confidence interval [CI]: 0.720-0.864) and the validation set (AUC 0.773, 95% CI: 0.668-0.877). The predictive model constructed using the clinical information alone was relatively less effective (AUC 0.711, 95% CI: 0.634-0.787). The predictive model constructed by integrating the radiomics features into the clinical information using the radiomics nomogram showed the best predictive ability and calibration in the training set (AUC 0.831, 95% CI: 0.765-0.897) and the validation set (AUC 0.816, 95% CI: 0.724-0.909). Decision curve analysis showed that radiomics nomogram has a certain clinical value. CONCLUSION The predictive model for surgical resection of IPA constructed by integrating the radiomics features and the clinical information based on the radiomics nomogram can help clinicians control the operative node and reduce the occurrence of overtreatment.

Abstract
Objective: To analyze the characteristics of ECG in patients with pulmonary hypertension(PH) and explore their correlation with pulmonary vascular resistance(PVR), mean pulmonary arterial hypertension(mPAP) and cardiac index(CI). Methods: A total of 186 patients with right heart catheterization were enrolled in the Department of Respiratory of the First Affiliated Hospital of Guangzhou Medical University from August 2015 to October 2017. Patients with normal pulmonary artery pressure, incomplete clinical data and repeated examinations were excluded and there were 101 patients with pulmonary hypertension included. The results of ECG parameters and right heart catheterization were collected to analyze the ECG characteristics of patients with different genders and their correlation with PVR, mPAP and CI. Results: Among all PH patients, the duration of QRS axial in male group was significantly longer than that of the female group [(110.38±15.829) vs. (98.63±18.041) ms, P<0.001], and the S wave amplitude in V5 was significantly higher compared to female group [(1.304±1.356) vs. (0.648±0.663) mv, P<0.001]. Their heart rate-corrected QT interval (QTc), QRS axis, S wave amplitude in Ⅰ, S and R wave amplitude in V1, R/S ratio in V1, S wave amplitude V5, all had a correlation with their PVR and the S wave amplitude in V1 was negatively correlated with PVR (r=-0.441, P<0.001). In the male group, PVR was not correlated with R/S ratio in V1 and S wave amplitude in V5. While PVR in the female group was significantly correlated with QTc, R wave amplitude in V1, R / S ratio in V1. In all PH patients, their P wave duration in Ⅱ, QRS axis and S wave amplitude in Ⅰ, S wave and R wave amplitude in V1, S wave amplitude in V5, QTc, R/S ratio in V1, all had correlations with mPAP (P<0.05). In male group, mPAP was not correlated with QTc, P wave duration in Ⅱ, and the S wave amplitude in V5 (P>0.05). The mPAP in the female group was only related to the S wave and R wave amplitude in V1, and S amplitude in Ⅰ and S wave amplitude in V5 (P<0.05). The CI was positively correlated with the S wave amplitude in V1 (r=0.34, P<0.001), and negatively correlated with the QRS axis (r=-0.219, P=0.04); CI in male group was not correlated with QRS axis(P=0.073), but correlated with QTc (r=-0.296, P=0.044). Conclusion: There were gender differences in QRS duration and S wave amplitude in V5 in patients with pulmonary hypertension. The QRS axis and the S wave amplitude in V1 were related to the heart index. There was a difference in the correlation between ECG and PVR, mPAP and CI in patients of different genders with pulmonary hypertension.

Abstract
PURPOSE To perform contrast analysis of the relationship between high-resolution computed tomography (HRCT) signs and new pathologic classification of small GGNs-like lung adenocarcinoma. MATERIALS AND METHODS The HRCT data from 145 pathologically confirmed cases of small GGNs of lung adenocarcinoma were analysed retrospectively. The 145 cases of GGNs were divided into pre-invasive (PI) group (n = 46), micro-invasive adenocarcinoma (MIA) group (n = 48), and invasive adenocarcinoma (IAC) group (n = 51). HRCT imaging sign of GGNs in each group was assessed and compared. RESULTS Significant differences in GGN size were found among the three groups (P < 0.05). The presence of a tumour-lung interface in the MIA and IAC groups was significantly higher than that in the PI group (P < 0.05), but no significant difference was found between the MIA and IAC groups. The presence of a pleural indentation sign in the IAC group was significantly higher than that in the other two groups (P < 0.05), but no significant difference was noted between the latter two groups. Significant differences were found in the lobulated and spicule signs among the three groups (P < 0.05). The presence of a microvascular sign in the MIA and IAC groups was significantly higher than that in the PI group (P < 0.05). No significant difference was found in the GGN density, vacuole sign, air bronchus sign and notch sign among the three groups. CONCLUSIONS The HRCT signs of GGNs could be used to differentiate among pre-invasive lesions, micro-invasive lesions and invasive lung adenocarcinoma.

Abstract
Objective: To evaluate the effects of polycyclic aromatic hydrocarbons (PAHs) and high risk human papillomavirus (HR-HPV) infection and their interaction on the progression of cervical intraepithelial neoplasia. Methods: A total of 486 patients, including 208 women with normal cervix (NC), 154 patients with low-grade cervical intraepithelial neoplasm (CINⅠ), 124 patients with high-grade cervical intraepithelial neoplasm (CINⅡ/Ⅲ), were selected from the cervical lesions cohort from June to December, 2014. HR-HPV was detected by using flow-through hybridization technology and the urine concentration of 1-hydroxypyrene (1-OHP) was detected with high performance liquid chromatography. By using software SPSS 22.0, the χ(2) test, trend χ(2) test, Kruskal-Wallis H test, Nemenyi rank test and Spearman rank correlation analysis were performed. And the interaction effects were evaluated by additive model. Results: The HR-HPV infection rates in NC, CINⅠ and CINⅡ/Ⅲ groups were 27.9%, 37.0% and 58.9%, respectively. The urine concentrations of 1-OHP (μmol/molCr) were 0.07±0.09, 0.11±0.10 and 0.17±0.15, respectively. With increasing severity of the cervical lesions, the HR-HPV infection rate gradually increased (trend χ(2)=29.89, P<0.001) and the high exposure rate of PAHs gradually increased (trend χ(2)=27.94, P<0.001). HR-HPV infection was positively correlated with 1-OHP exposure (r=0.680, P<0.001). There was a positive additive interaction between HPV infection and PAHs exposure in CIN Ⅱ/Ⅲ group, but it was not found in CIN Ⅰ group. Conclusion: Both HR-HPV infection and high exposure of PAHs might increase the risk of cervical intraepithelial neoplasm, and might have a synergistic effect on the progression of high-grade cervical intraepithelial neoplasia.

Abstract
To observe the effect of Soyisoflavones (SI) on the expression of Wnt/β-catenin signaling pathway elements, transforming growth factor-β (THGF-β) and its related proteins in the renal interstitia of diabetic nephropathic (DN) rats, 48 DN rats were randomly divided into 4 groups: DN model group (group DN), soybean isoflavone treatment group (group DA), DN model group + losartan treatment group (group DL), DN model group + soybean isoflavones combined with losartan treatment group (group SL). Each group comprised 12 rats. Twelve healthy Wistar rats were selected as normal controls (group N). After 12 weeks of continuous administration of soybean isoflavone or losartan or those two combined, the body weight of rats was recorded and serum urea nitrogen (BUN) and creatinine (Scr) were measured. The expression of Wnt4, β-catenin, and TGF-β1 proteins, as well as mRNA, in the renal interstitium were detected by immunohistochemistry and real-time quantitative PCR (FQ-PCR). In all the groups, Wnt4, β-catenin and TGF-β1 protein were only expressed in renal interstitial and renal tubular epithelial cells. There was no significant difference between group DA and group DL (P>0.05). FQ-PCR results showed that Wnt4, β-catenin and TGF-β1 mRNA were consistent with the expression of these proteins in the renal tissue of each group. Soy isoflavones can reduce 24-h urinary protein quantification, alleviate renal interstitial pathological damage, and regulate the expression of Wnt4, β-catenin and TGF-β1 in the renal interstitium. This suggests that soybean isoflavones could delay the process of renal interstitial fibrosis in DN rats by decreasing the expression of Wnt4, β-catenin and TGF-β1 in the renal interstitium, thus demonstrating that soybean isoflavones plus losartan have the best protective effects against diabetes-induced renal fibrosis.

Abstract
Quantifying coherence has received increasing attention, and considerable work has been directed towards finding coherence measures. While various coherence measures have been proposed in theory, an important issue following is how to estimate these coherence measures in experiments. This is a challenging task, since the state of a system is often unknown in practical applications and the accessible measurements in a real experiment are typically limited. In this Letter, we put forward an approach to estimate coherence measures of an unknown state from any limited experimental data available. Our approach is not only applicable to coherence measures but can be extended to other resource measures.

Abstract
Objective: To analyze and investigate the survival time of dead HIV/AIDS patients after antiretroviral therapy (ART) and related factors in Henan province. Methods: The database of national integrated management system of HIV/AIDS was used to collect the information of dead patients who received ART between January 2003 and December 2015. Software SPSS 23.0 was used to analyze the survival time of dead patients and related factors. Result: A total of 6 267 AIDS patients died after ART and the average survival time was 23.85 months (Q(R): 6.87-50.46 months). Within 6 months, 7-12 months and 13-24 months after ART, the numbers of dead patients were 1 441 (23.00%), 652 (10.40%) and 1 052 (16.79%), respectively. The number of dead cases decreased after 24 months of ART. The number of AIDS-related deaths was 5 085 (81.1%); and 799 (12.7%) deaths were due to other causes, in which 179 (2.9%) were caused by accidents and 109 (1.7%) were caused by suicides. The differences in annual composition ratio of death causes during 2003-2015 had significance (χ(2)=864.27, P<0.01). Twelve months, 36 months, 60 months and 120 months after ART, the survival ratios were 66.59%, 36.62%, 19.24% and 0.64% respectively. Compared with patients infected through blood donation, the HR of the patients infected through sexual transmission was 1.602 (95%CI: 1.483-1.732). Compared with patients with initial level of CD(4)(+)T lymphocyte ≥350 unit/μl, the HR of patients with initial level of CD(4)(+)T lymphocyte<50 unit/μl was 2.320 (95%CI: 2.119-2.539). Compared with patients receiving second line ART, the HR of patients receiving no second line ART was 3.312 (95%CI: 3.083-3.558). Conclusion: The AIDS related deaths mainly occurred in the first six months after ART. As the increase of duration of ART, the death rate decreased. Sexual transmission, low initial level of CD(4)(+)T lymphocyte and receiving no second line ART were the risk factors for the deaths of HIV/AIDS patients.

Abstract
Spinal fusion is the classic treatment to achieve spinal stability for the treatment of the spinal disease. Generally, spinal fusion still has to combine a certain of bone matrix for promoting bone formation to achieve the desired fusion effect based on the surgery, including the traditional bone matrix, such as the autologous bone, allografts and xenografts. Nevertheless, some problems still existed such as the immunogenic problems, the secondary wound, and pathogenic transfer and so on. Here the injectable thermosensitive hydrogel could substitute to avoid the problems as a potential biological scaffold for tissue engineering. Once injected, they could fill in the irregular-shaped cavity and change to a gel state at physiological temperature. We wanted to design the collagen/n-HA/BMP-2@PCEC/PECE hydrogel composites based on previous work about collagen/n-HA/PECE hydrogel to exhibit better performance in guiding spinal fusion because of the addition of BMP-2@PCEC nanoparticles (PCEC, PCL-PEG-PCL). However, when the hydrogels were injected, one of the surfaces was in contact with the spine, but others were in contact with soft tissue like muscles and fascia. The release behavior was the same at the different surfaces, so the factors could be released into the soft tissue, and it may then be consumed or lead to ectopic bone formation. The hydrogel composites should be improved to adjust the direction of the releaser behavior. In consequence, we wrapped an electrostatic spinning nanofiber membrane possessing hydrophobicity around the hydrogels. In this study, we developed a system that the collagen/n-HA/BMP-2@PCEC/PECE hydrogels were wrapped with the hydrophobicity PDLLA electrospun nanofiber membrane, setting up a barrier between the hydrogels and the soft tissue. The system could exhibit biocompatibility, preventing the factors from escaping to keep their retention in the needed places of osteogenesis; the results demonstrated that it showed an excellent effect on spinal fusion.

Abstract
Objective: To investigate the mechanism of brain-derived neurotrophic factor (BDNF) promoting induced pluripotent stem cells (iPSCs) to differentiate into neural stem cells (NSCs) via Wnt/β-catenin and extracellular signal-regulated kinase/mitogen-activated protein kinases (ERK/MAPK) signal pathways. Methods: iPSCs were cultured and identified. The iPSCs were induced to differentiate into NSCs by BDNF and retinoic acid (RA). Nestin was detected by immunofluorescence and flow cytometry after iPSCs differentiated. The technique of small interfering RNA (siRNA) was used to silence the gene expression of β-catenin and ERK, and iPSCs were divided into control group, BDNF group (adding 10 μg/L BDNF), siRNA-ERK/BDNF group (transfected with siRNA-ERK and adding 10 μg/L BDNF) and siRNA-β-catenin/BDNF group (transfected with siRNA-β-catenin and adding 10 μg/L BDNF). Real-time polymerase chain reaction (RT-PCR) and Western blotting were used to detect the mRNA and protein expression of key elements of Wnt/β-catenin and ERK/MAPK signaling pathways, included β-catenin, ERK1/2, c-fos, c-jun, and c-myc. The least significant difference test was used when data were compared between groups. Results: The immunofluorescence showed that iPSCs expressed octamer-binding transcription factor-4 (Oct4), SRY-related HMG box protein-2 (Sox2) and Nanog genes. The flow cytometry showed that Nestin-positive cells were 78.7% for BDNF and 43.5% for RA, and it was only 7.8% for routine medium. Compared with those in the control group, the mRNA expression of β-catenin, ERK1/2, c-fos, c-jun, and c-myc in the BDNF group were upregulated significantly (t=2.80, 2.318, 2.255, 1.799, 1.582, 1.663, all P<0.05), and the same results were acquired with the protein expression (t=2.805, 2.318, 2.255, 1.799, 1.582, 1.663, all P<0.050). Compared with those in BDNF group, the mRNA and protein expression of ERK1/2 in siRNA-ERK/BDNF group down-regulated obviously (t=1.917, 2.042, 1.673, 1.540, all P<0.05), and the mRNA and protein expression of c-fos and c-jun were down-regulated (t=1.022, 0.907, 0.848, 0.801, all P<0.05). However, the mRNA and protein expression of β-catenin and c-myc were not suppressed by siRNA-ERK (t=0.216, 0.185, 0.097, 0.112, all P>0.05). In siRNA-β-catenin/BDNF group, the mRNA and protein expression of β-catenin and c-myc was obviously down-regulated when compared with those in BDNF group (t=3.104, 2.774, 2.235, 1.911, all P<0.05), and expression of ERK1/2, c-fos and c-jun were down-regulated too (t=0.776-1.192, all P<0.05). Conclusion: BDNF promotes the differentiation of iPSCs by activating Wnt/β-catenin and ERK/MAPK signal pathway, there should be cross-talk between the two signal pathways, and c-fos and c-jun may be common nuclear transcription factors.

Abstract
Objective: To investigate the expression of SnoN in human hypertrophic scar fibroblasts and the mechanism of its participation in hypertrophic scar formation. Methods: Eight patients with hypertrophic scar after burn in need of surgery were admitted in our unit from January to October 2013, and then hypertrophic scar tissue and normal skin tissue of full-thickness skin donor site resected by surgery of the patients were collected. Hypertrophic scar fibroblasts and normal skin fibroblasts of patients were isolated with method of explant culture and then sub-cultured. Cells of the third to fifth passage were used in the following experiments. (1) The protein expressions of SnoN of hypertrophic scar fibroblasts and normal skin fibroblasts were assessed with Western blotting. (2) The mRNA expressions of SnoN of another batch of hypertrophic scar fibroblasts and normal skin fibroblasts were determined with reverse transcription polymerase chain reaction. (3) Another batch of hypertrophic scar fibroblasts and normal skin fibroblasts were treated with 10 ng/mL transforming growth factor beta1 (TGF-β(1)) for 30 min, 1 h, 2 h, and 6 h, respectively, and then the protein expressions and mRNA expressions of SnoN of untreated cells and treated cells were detected as above. Data were processed with one way analysis of variance and independent sample t test. Results: (1) The protein expression of SnoN of hypertrophic scar fibroblasts was 0.020±0.003, significantly lower than that of normal skin fibroblasts (0.032±0.005, t=7.19, P<0.05). (2) The mRNA expression of SnoN of hypertrophic scar fibroblasts was 0.407±0.157, with no significant difference from that of normal skin fibroblasts (0.339±0.095, t=-1.29, P>0.05). (3) The protein expression of SnoN of normal skin fibroblasts was increased in a time-dependent fashion with the TGF-β(1) stimulation, and the protein expressions of SnoN of cells treated with TGF-β(1) for 30 min, 1 h, 2 h, and 6 h were significantly higher than those of untreated cells (with t values from 2.27 to 27.89, P values below 0.05). The protein expression of SnoN of hypertrophic scar fibroblasts was decreased in a time-dependent fashion with the TGF-β(1) stimulation, and the protein expressions of SnoN of cells treated with TGF-β(1) for 30 min, 1 h, 2 h, and 6 h were obviously lower than those of untreated cells (with t values from 10.80 to 13.85, P values below 0.05). (4) The mRNA expressions of SnoN of normal skin fibroblasts and hypertrophic scar fibroblasts were both increased in a time-dependent fashion with the TGF-β(1) stimulation, and the mRNA expressions of SnoN of the two types of cells treated with TGF-β(1) for 30 min, 1 h, 2 h, and 6 h were both significantly higher than those of untreated cells (with t values from 18.16 to 58.22, P values below 0.05). Conclusions: The protein expression of SnoN in hypertrophic scar fibroblasts is reduced, which weakens its inhibitory effect on TGF-β(1) signal, thus amplifying the TGF-β(1) signal, and it may participate in the formation of hypertrophic scar.

Abstract
Serpins are a broadly distributed family of proteases found in various organisms that play an important role in regulating the immune response. Here, we identified a serpin-1 gene from Antheraea pernyi that encodes a 279 amino acid protein with a molecular weight of 30.8 kDa. We expressed the recombinant Ap-serpin-1 protein in Escherichia coli and used the purified protein to prepare rabbit anti-Ap-serpin-1 polyclonal antibodies. We calculated the enzyme-linked immunosorbent assay titer of the antibody as 1:128000. Quantitative real-time polymerase chain reaction analysis revealed that Ap-serpin-1 was expressed in all examined tissues, including hemolymph, malpighian tubules, midgut, silk gland, integument and the fat body; the highest Ap-serpin-1 expression levels was detected in the fat body. We next investigated the expression patterns of Ap-serpin-1 in both fat body and hemolymph samples, following treatment with E. coli, Beauveria bassiana, Micrococcus luteus and nuclear polyhedrosis virus (NPV). We reported that NPV and M. luteus significantly enhanced Ap-serpin-1 expression in the fat body. While, in the hemolymph samples, treatment with B. bassiana and M. luteus was shown to upregulate Ap-serpin-1 expression at 24 h induction. Altogether, our results suggest that Ap-serpin-1 is involved in the innate immunity of A. pernyi.

Abstract
As a β2 integrin family member, Mac-1 plays an important role in the inflammatory response. Inflammation and lung injury are closely associated, but the involvement of Mac-1 in the occurrence and development of such pathologies remains poorly understood. We aimed to investigate the relationship between Mac-1 deficiency and respiratory failure in Mac-1 knockout {Mac-1-/-} mice, using C57BL/6J mice as a control. The newborn survival rate of Mac-1-/- mice was calculated, and mouse lung tissue was treated with hematoxylin and eosin and subjected to immunofluorescent staining. Moreover, western blotting and immunohistochemistry were used to detect the expression of molecules specific to type I and type II alveolar epithelial cells, as well as alveolar surfactant proteins secreted by the latter. Survival of Mac-1-/- pups was significantly lower than that of newborn C57BL/6J mice. In a float test, lung tissues from C57BL/6J mice were buoyant, whereas those of Mac-1-/- mice were not. Compared with C57BL/6J mice, expression of proSP-C {specific to type II alveolar epithelial cells} and alveolar surfactant proteins in Mac-1-/- mice was not significantly different, implying that type II cell function was unaltered. However, western blotting revealed expression of T1α, Aqp5, and Snx5 {type I alveolar epithelial cell markers} in Mac-1-/- mice to be significantly decreased {P < 0.05}. In conclusion, Mac-1 may play an important role in respiratory failure. Its absence leads to this condition not by influencing type II alveolar epithelial cells or their secreted surfactant proteins, but rather by reducing type I alveolar cell numbers.

Abstract
Objective: To explore the effect of polycyclic aromatic hydrocarbons (PAHs) and p16, FHIT gene CpG island methylation, as well as their interaction in cervical intraepithelial neoplasias. Methods: Objects of this study were from a cohort of cervical lesions study in Yangqu county of Shanxi province. All the patients were diagnosed pathologically, that including 83 patients with high-grade cervical intraepithelial neoplasia (CINⅡ/Ⅲ), 86 patients with low-grade cervical intraepithelial neoplasia (CINⅠ) and another 91 women under normal cervical (NC) condition. 1-hydroxy pyrene in the urine was detected by high performance liquid chromatography (HPLC) while CpG island methylation status of tumor suppressor gene p16 and FHIT were measured by methylation-specifc polymerase chain reaction (MSP). Data were analyzed with Kruskal-Wallis H test, chi-square test and trend of chi-square test. Logistic regression models were used to estimate the odds ratio (OR) and corresponding 95% confidence intervals (95%CI) between influencing factors and the cervical disease by using the SPSS statistical software (version 20.0). The interaction under study was evaluated by using the generalized multifactor dimensionality reduction (GMDR) model. Results: Level of 1-hydroxy pyrene (H=50.743, P<0.001) and the high exposure rate of 1-hydroxy pyrene (trend χ(2)=20.146, P<0.001) were gradually increasing along with the severity of cervical intraepithelial neoplasia. The CpG island methylation rates of p16, FHIT in CINⅠand CINⅡ/Ⅲ group were higher than that in NC group, and gradually increasing along with the severity of cervical intraepithelial neoplasia (trend χ(2)=9.75, P=0.002; trend χ(2)=10.39, P=0.001). Results from the GMDR model showed that interaction existed among the high exposure of 1-hydroxy pyrene and the CpG island methylation of p16, FHIT in CINⅠ and CINⅡ/Ⅲ group. Conclusion: Under the high exposure of 1-hydroxy pyrene and the CpG island methylation of p16, FHIT appeared to have increased the risk of cervical intraepithelial neoplasia and causing synergistic effect in cervical intraepithelial neoplasia.

Abstract
Objective: To explore the effects of silencing Smad ubiquitination regulatory factor 2 (Smurf2) on the secretion of transforming growth factor beta 1 (TGF-β(1)), alpha-smooth muscle actin (α-SMA), and collagen type Ⅰ by human hypertrophic scar-derived fibroblasts. Methods: The human normal skin-derived fibroblasts and hypertrophic scar-derived fibroblasts were cultured with explant culture technique from the normal skin and hypertrophic scar tissue, which was obtained from 9 patients with hypertrophic scars after burn. Two kinds of fibroblasts of the third passage were both divided into 6 groups according to the random number table, with 9 wells in each group. Fibroblasts in blank control group were cultured for 72 h without transfection of any small interfering RNA (siRNA), fibroblasts in negative control group were for cultured for 72 h after transfected with non-target siRNA, fibroblasts in Smurf2 siRNA group were cultured for 72 h after transfected with 100 nmol/L Smurf2 siRNA, fibroblasts in blank control+ TGF-β(1) group were cultured for 72 h without transfection of any siRNA and then treated with 10 ng/mL TGF-β(1) for 6 h, fibroblasts in negative control+ TGF-β(1) group were cultured for 72 h after transfected with non-target siRNA and then treated with 10 ng/mL TGF-β(1) for 6 h, fibroblasts in Smurf2 siRNA+ TGF-β(1) group were cultured for 72 h after transfected with Smurf2 siRNA and then treated with 10 ng/mL TGF-β(1) for 6 h. (1) The protein and mRNA expression levels of Smurf2 of the two kinds of cells in blank control group, negative control group, and Smurf2 siRNA group were assessed by Western blotting and reverse transcription-polymerase chain reaction (RT-PCR), respectively. (2) The content of TGF-β(1) in the cell culture supernatant of the two kinds of cells in blank control group and Smurf2 siRNA group was determined by enzyme-linked immunosorbent assay (ELISA). (3) The protein expression levels of α-SMA of the two kinds of cells in the 6 groups were assessed by Western blotting. The content of collagen type Ⅰ in the cell culture supernatant of the two kinds of cells in the 6 groups was determined by ELISA. (4) The mRNA expression levels of α-SMA and collagen type Ⅰ of the two kinds of cells in the 6 groups were assessed by RT-PCR. The sample numbers of each group in the above experiments were all 9. Data were processed with analysis of variance of factorial design and Bonferroni test. Results: (1) The protein and mRNA expression levels of Smurf2 of the two kinds of cells in Smurf2 siRNA group were significantly lower than those in blank control group and negative control group (with P values below 0.05). The protein and mRNA expression levels of Smurf2 of the two kinds of cells in blank control group and negative control group were close (with P values above 0.05). (2) The content of TGF-β(1) in the cell culture supernatant of hypertrophic scar-derived fibroblasts in blank control group and Smurf2 siRNA group was respectively (4.34±0.56) and (2.14±0.28) pg/mL, which was significantly higher than (1.52±0.20) and (1.41±0.18) pg/mL of normal skin-derived fibroblasts respectively (with P values below 0.05). In hypertrophic scar-derived fibroblasts, the content of TGF-β(1) in the cell culture supernatant in Smurf2 siRNA group was significantly lower than that in blank control group (P<0.05). In normal skin-derived fibroblasts, the content of TGF-β(1) in the cell culture supernatant in Smurf2 siRNA group was close to that in blank control group (P>0.05). (3) The protein expression levels of α-SMA and content of collagen type Ⅰ in the cell culture supernatant of the two kinds of cells in blank control+ TGF-β(1) group were significantly higher than those in blank control group (with P values below 0.05). The protein expression levels of α-SMA and content of collagen type Ⅰ in the cell culture supernatant of the two kinds of cells in negative control+ TGF-β(1) group were significantly higher than those in negative control group (with P values below 0.05). The protein expression levels of α-SMA and content of collagen type Ⅰ in the cell culture supernatant of the two kinds of cells in Smurf2 siRNA group were close to those in blank control group and negative control group (with P values above 0.05). The protein expression levels of α-SMA and content of collagen type Ⅰ in the cell culture supernatant of the two kinds of cells in Smurf2 siRNA+ TGF-β(1) group were significantly lower than those in blank control+ TGF-β(1) group and negative control+ TGF-β(1) group (with P values below 0.05). (4) The mRNA expression levels of α-SMA and collagen type Ⅰ of the two kinds of cells in blank control+ TGF-β(1) group were significantly higher than those in blank control group (with P values below 0.05). The mRNA expression levels of α-SMA and collagen type Ⅰ of the two kinds of cells in negative control+ TGF-β(1) group were significantly higher than those in negative control group (with P values below 0.05). The mRNA expression levels of α-SMA and collagen type Ⅰ of the two kinds of cells in Smurf2 siRNA group were close to those in blank control group and negative control group (with P values above 0.05). The mRNA expression levels of α-SMA and collagen type Ⅰ of the two kinds of cells in Smurf2 siRNA+ TGF-β(1) group were significantly lower than those in blank control+ TGF-β(1) group and negative control+ TGF-β(1) group (with P values below 0.05). Conclusions: Silencing Smurf2 in human hypertrophic scar-derived fibroblasts can reduce the autocrine of TGF-β(1) and inhibit the TGF-β(1)-induced α-SMA expression and collagen type Ⅰ synthesis.

Abstract
Objective To evaluate the validity of two abbreviated protocols (AP) of MRI in breast cancer screening of dense breast tissue. Materials and Methods This was a retrospective study in 356 participants with dense breast tissue and negative mammography results. The study was approved by the Nanjing Medical University Ethics Committee. Patients were imaged with a full diagnostic protocol (FDP) of MRI. Two APs (AP-1 consisting of the first post-contrast subtracted [FAST] and maximum-intensity projection [MIP] images, and AP-2 consisting of AP-1 combined with diffusion-weighted imaging [DWI]) and FDP images were analyzed separately, and the sensitivities and specificities of breast cancer detection were calculated. Results Of the 356 women, 67 lesions were detected in 67 women (18.8%) by standard MR protocol, and histological examination revealed 14 malignant lesions and 53 benign lesions. The average interpretation time of AP-1 and AP-2 were 37 seconds and 54 seconds, respectively, while the average interpretation time of the FDP was 3 minutes and 25 seconds. The sensitivities of the AP-1, AP-2, and FDP were 92.9, 100, and 100%, respectively, and the specificities of the three MR protocols were 86.5, 95.0, and 96.8%, respectively. There was no significant difference among the three MR protocols in the diagnosis of breast cancer (p > 0.05). However, the specificity of AP-1 was significantly lower than that of AP-2 (p = 0.031) and FDP (p = 0.035), while there was no difference between AP-2 and FDP (p > 0.05). Conclusion The AP may be efficient in the breast cancer screening of dense breast tissue. FAST and MIP images combined with DWI of MRI are helpful to improve the specificity of breast cancer detection.

Abstract
RATIONALE AND OBJECTIVES The study aimed to evaluate the usefulness of an abbreviated protocol (AP) of magnetic resonance imaging (MRI) in comparison to a full diagnostic protocol (FDP) of MRI in the breast cancer screening with dense breast tissue. MATERIALS AND METHODS There are 478 female participants with dense breast tissue and negative mammography results, who were imaged with MRI using AP and FDP. The AP and FDP images were analyzed separately, and the sensitivity and specificity of breast cancer detection were calculated. The chi-square test and receiver operating characteristics curves were used to assess the breast cancer diagnostic capabilities of the two protocols. RESULTS Sixteen cases of breast cancer from 478 patients with dense breasts were detected using the FDP method, with pathologic confirmation of nine cases of ductal carcinoma in situ, six cases of invasive ductal carcinoma, and one case of mucinous carcinoma. Fifteen cases of breast cancer were successfully screened using the AP method. The sensitivity showed no obvious significant difference between AP and FDP (χ2 = 0.592, P = 0.623), but the specificity showed a statistically significant difference (χ2 = 4.619, P = 0.036). The receiver operating characteristics curves showed high efficacy of both methods in the detection of breast cancer in dense breast tissue (the areas under the curve were 0.931 ± 0.025 and 0.947 ± 0.024, respectively), and the ability to diagnose breast cancer was not statistically significantly different between the two methods. CONCLUSIONS The AP of MRI may improve the detection rate of breast cancer in dense breast tissue, and it may be useful in efficient breast cancer screening.

Abstract
To investigate the role of the P2X7 receptor in learning and memory dysfunction induced by HIV-1 envelope glycoprotein gp120 (gp120), we established HIV-1-associated dementia (HAD) animal models by intracerebroventricular (ICV) infusion of gp120 in rats. We observed gp120-induced cognitive dysfunction in the radial arm water maze test. Results showed that rats in the gp120 groups had longer escape latencies and more errors compared to those in the control group. For example, the average trial time in the 50-ng/day-gp120 group on day eight (16.57 ± 1.71 s, N = 90) was significantly longer than that of control rats (9.93 ± 0.68 s, N = 90). The relative expression of P2X7 mRNA in the control, 50-, 70-, and 100-ng/day-gp120 groups were 0.43 ± 0.06, 0.48 ± 0.07, 0.83 ± 0.05, and 0.84 ± 0.10, respectively; relative P2X7 protein expression in those groups was 0.63 ± 0.07, 1.08 ± 0.06, 0.90 ± 0.07, and 1.03 ± 0.11, respectively. According to immunohistochemistry analysis, the staining intensity values for P2X7 protein expression in the control, 50-, 70-, and 100-ng/d-gp120 groups were 0.88 ± 0.07, 1.41 ± 0.12, 1.28 ± 0.13, and 1.31 ± 0.10, respectively. The above results showed that the expression of P2X7 increased significantly in the hippocampus of gp120 rats compared to that of the control group. These results suggest that ICV infusion of gp120 can successfully mimic HAD in rats, and P2X7 may be involved in gp120-induced cognitive dysfunction. This could provide a theoretical foundation and potential drug target for research and treatment of ADC.

Abstract
Cyclophosphamide (CY) is a DNA alkylating agent, which is widely used with other chemotherapy drugs in the treatment of various types of cancer. It can be used not only as a chemotherapeutic but also as an immunomodulatory agent to inhibit IL-10 expression and T regulatory cells (Tregs). Fibroblast activation protein α (FAPα) is expressed in cancer-associated fibroblasts in the tumor microenvironment. Immunotherapy based on FAPα, as a tumor stromal antigen, typically induces specific immune response targeting the tumor microenvironment. This study evaluated the efficacy of a previously unreported CY combination strategy to enhance the limited anti-tumor effect of a DNA vaccine targeting FAPα. The results suggested CY administration could promote the percentage of splenic CD8+ T cells and decrease the proportion of CD4 + CD25 + Foxp3+ Tregs in spleen. In tumor tissues, levels of immunosuppressive cytokines including IL-10 and CXCL-12 were also reduced. Meanwhile, the CY combination did not impair the FAPα-specific immunity induced by the DNA vaccine and further reduced tumor stromal factors. Most importantly, FAP-vaccinated mice also treated with CY chemotherapy showed a marked suppression of tumor growth (inhibition ratio =80%) and a prolongation of survival time. Thus, the combination of FAPα immunotherapy and chemotherapy with CY offers new insights into improving cancer therapies.

Abstract
The aim of this study was to evaluate and compare the colour stabilities of three types of orthodontic clear aligners exposed to staining agents in vitro. Sixty clear orthodontic aligners produced by three manufacturers (Invisalign, Angelalign, and Smartee) were immersed in three staining solutions (coffee, black tea, and red wine) and one control solution (distilled water). After 12-h and 7-day immersions, the aligners were washed in an ultrasonic cleaner and measured with a colourimeter. The colour changes (ΔE*) were calculated on the basis of the Commission Internationale de I'Eclairage L*a*b* colour system (CIE L*a*b*), and the results were then converted into National Bureau of Standards (NBS) units. Fourier transformation infrared (FT-IR) spectroscopy and scanning electron microscopy (SEM) were conducted to observe the molecular and morphologic alterations to the aligner surfaces, respectively. The three types of aligners exhibited slight colour changes after 12 h of staining, with the exception of the Invisalign aligners stained with coffee. The Invisalign aligners exhibited significantly higher ΔE* values (ranging from 0.30 to 27.81) than those of the Angelalign and Smartee aligners (ΔE* values ranging from 0.33 to 1.89 and 0.32 to 1.61, respectively, P<0.05). FT-IR analysis confirmed that the polymer-based structure of aligners did not exhibit significant chemical differences before and after the immersions. The SEM results revealed different surface alterations to the three types of aligner materials after the 7-day staining. The three types of aesthetic orthodontic appliances exhibited colour stability after the 12-h immersion, with the exception of the Invisalign aligners stained by coffee. The Invisalign aligners were more prone than the Angelalign and Smartee aligners to pigmentation. Aligner materials may be improved by considering aesthetic colour stability properties.

Abstract
Objective: To investigate the TNFAIP3/A20 abnormalities and its association with Epstein-Barr virus (EBV) in classical Hodgkin lymphoma (CHL). Methods: Formalin-fixed, paraffinembedded tissue blocks of 54 CHL patients were collected and subjected to the construction of tissue microarray (TMA) for further analyses. EBV status was evaluated by in situ hybridization (ISH) for EBER1/2 and immunohistochemistry (IHC) with anti-LMP-1 antibody. Fluorescence in situ hybridization (FISH) and IHC were performed to determine the copy number alterations of TNFAIP3 and A20 protein expression respectively. Results: The concordance rate of IHC for LMP-1 and ISH for EBER1/2 was100%, and 25.9% (14/54) cases were identified with EBV infection. Immunohistochemistry analysis demonstrated 27.8% (15/54) cases with A20 expression deficiency. Of the 54 cases tested for A20 expression, 49 cases were simultaneously analyzed by FISH, which showed 10 (20.4% ) cases harboring TNFAIP3 deletion. However, discrepancy was observed between the results of A20 by IHC and TNFAIP3 deletion by FISH. Only 1 case with TNFAIP3 deletion demonstrated complete loss of A20 immunoreactivity. In addition, comparison of the frequency of either A20 expression loss or TNFAIP3 deletion between EBV-positive and-negative cases did not reveal any significance (P>0.05). Conclusion: TNFAIP3 deletion could be observed in both EBV-positive and - negative CHL cases. A20 expression by IHC could not confirm TNFAIP3 deletion by FISH, which might be related to the technical issues.
