Abstract
Objective: To explore the function and mechanism of transcription factor En1 in esophageal squamous cell carcinoma (ESCC). Methods: The correlations of En1 with prognosis were analyzed using the overall survival data of 9 397 pan-cancer patients and progression-free survival data of 4 349 pan-cancer patients from The Cancer Genome Atlas (TCGA) database. The En1 expression data in 53 and 155 cases of ESCC and their paired adjacent tissues were from Gene Expression Omnibus (GEO) database and National Genomics Data Center-Genome Sequence Archive(NGDC-GSA)database. Lentivirus was used to generate En1 stable knockout cell lines KYSE180 and KYSE450. The proliferation ability of the cells was detected by cell counting kit 8 and clone formation assay. The migration ability of the cells was detected by Transwell assay. The effect of En1 on the proliferation of ESCC was detected by xenograft experiment in BALB/c-nu/nu mice. Real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) was used to detect the expressions of En1, glioma-associated oncogene family zinc finger 1 (GLI1), glioma-associated oncogene family zinc finger 2 (GLI2) and smoothened (SMO). Results: Pan-cancer data from TCGA showed that patients with low En1 expression had longer overall survival and progression-free survival than patients with high En1 expression (P< 0.001). Data from GEO and GSA databases also showed a high expression level of En1 in ESCC tissues compared with paired tissues (P<0.001). Proliferation was inhibited after knockout of En1 in KYSE180 and KYSE450 cells (P<0.001). The colony formation numbers decreased. The colony formation numbers of KYSE180 cells in the shEn1#1 group and the shEn1#2 group were 138.33±23.07 and 127.00±19.70, respectively, significantly lower than that of the shNC group 340.67±12.06 (P<0.001). The colony formation numbers of KYSE450 cells in the shEn1#1 group and the shEn1#2 group were 65.33±2.52 and 9.00±3.00, respectively, significantly lower than that of the shNC group 139.00±13.00 (P<0.001). The migration numbers was inhibited after knockout of En1 [the Transwell numbers of KYSE180 cells in the shEn1#1 group and the shEn1#2 group were 66.67±12.66 and 71.33±11.02, respectively, significantly lower than that of the shNC group 334.67±16.56 (P<0.001). The Transwell numbers of KYSE450 cells in the shEn1#1 group and the shEn1#2 group were 112.33±14.57 and 54.33±5.51, respectively, significantly lower than that of the shNC group 253.33±21.03 (P<0.001)]. Xenograft model showed a slower growth rate of shEn1#1 and shEn1#2 cell lines (P<0.001). The tumor weights of KYSE450 cells in the shEn1#1 group and the shEn1#2 group were (0.046±0.026)g and (0.047±0.025)g, respectively, significantly lower than that of the shNC group (0.130±0.038)g (P<0.001). After knockdown of En1, the relative expression levels of GLI1 in KYSE180 cells of the shEn1#1 group and the shEn1#2 group were 0.326±0.162 and 0.322±0.133, and the relative expression levels of GLI1 in KYSE450 cells of the shEn1#1 and shEn1#2 groups were 0.131±0.006 and 0.352±0.050, respectively, which were all lower than that in the shNC group (P<0.01). After knockdown of En1, overexpression of GLI1 attenuated the inhibitory effect of knockdown of En1 on cell proliferation (P<0.001), colony formation[the colony formation numbers of the shEn1#1-GLI1 group were 151.00±9.54, higher than 102.33±10.02 (P=0.004) of the shEn1#1-vector group] and migration [the migration numbers of the shEn1#1-GLI1 group were 193.67±10.07, higher than 109.33±11.50 (P<0.001) in the shEn1#1-vector group]. In clinical samples of ESCC, major regulatory factors of the Hedgehog pathway were up-regulated and the pathway was activated. Conclusion: En1 promotes the proliferation and migration of ESCC cells by regulating the Hedgehog pathway and can be used as a new potential target for targeted therapy of ESCC.

Abstract
Objective: To observe the feelings of listening to music and the importance of music in the daily life of post-lingual deaf adults with cochlear implants, and to explore the relevant influencing factors. Methods: This was a cross-sectional survey study. From January 2021 to August 2021,the Music-Related Quality of Life Scale was used to evaluate the music needs and music experiences of 63 post-lingual deaf adults who met the inclusion criteria, including 27 males and 36 females, aged (40.7±12.3) years, at the time of surgery (36.8±13.1) years, and with a preoperative hearing aid ineffective time of (3.9±5.8) years. Indicators analyzed included age, duration of ineffective preoperative hearing aid wear, preoperative music preference, duration of postoperative cochlear implant use, current hearing aid modality, and auditory rehabilitation outcomes. Whether the six factors mentioned above constituted an influence on the subjects' music listening was investigated using SPSS 25.0 statistical software. Results: All of the observations in the scale were correlated with a single factor. The two sub-dimensions of music experience section were related to the effect of auditory rehabilitation. In the importance section, the effect of auditory rehabilitation was the influential factor of the dimension of "participation importance", and the preoperative enjoyment of music was the relevant influential factor of the dimension of "perceived importance". There was a significant difference between the groups when they were grouped by the above factors (P value<0.05), while there was no statistically significance between the groups when they were grouped by other factors (P value>0.05). Conclusions: Post-lingual deaf adults show the need and attempt to listen to music after cochlear implantation. The effectiveness of auditory rehabilitation and the degree of music preference preoperatively are two important factors that influence music listening in implant recipients. Once the level of auditory communication has been restored to a certain degree, it is important to pay more attention to the needs of music for implant recipients and train them in time, especially for those with music preferences preoperatively.

Abstract
AIM To develop and validate a non-invasive computed tomography (CT)-based radiomics model for predicting vasculogenic mimicry (VM) status in lung adenocarcinoma (LA). MATERIALS AND METHODS Two hundred and three patients with LA were enrolled retrospectively and grouped into training and test groups with a ratio of 7:3. Uni- and multivariate logistic regression analyses were performed in the training cohort to screen the independent clinical and radiological factors for VM, and the clinical model was then established. A radiomics model was established based on the rad-scores through support vector machine (SVM). A radiomics nomogram model was subsequently constructed by combining the rad-score with clinical-radiological factors. The receiver operating characteristic curve (ROC), calibration curves, and decision curve analysis (DCA) were conducted to evaluate the performance of the three models. RESULTS Nine selected radiomics features were selected for the radiomics model and the maximum length and spiculation sign were constructed for the clinical model. The radiomics nomogram model integrating the maximum length, spiculation sign, and rad-score yielded the best AUC in both the training (AUC = 0.925) and test cohorts (AUC = 0.978), in comparison with the radiomics model (AUC = 0.907 and 0.964, in both the training and test cohorts) and the clinical model (AUC = 0.834 and 0.836 in both training and test cohorts). CONCLUSIONS The CT-based radiomics nomogram model showed satisfying discriminating performance for preoperatively and non-invasively predicting VM expression status in LA patients.

Abstract
Post-surgical treatments of the human throat often require continuous monitoring of diverse vital and muscle activities. However, wireless, continuous monitoring and analysis of these activities directly from the throat skin have not been developed. Here, we report the design and validation of a fully integrated standalone stretchable device platform that provides wireless measurements and machine learning-based analysis of diverse vibrations and muscle electrical activities from the throat. We demonstrate that the modified composite hydrogel with low contact impedance and reduced adhesion provides high-quality long-term monitoring of local muscle electrical signals. We show that the integrated triaxial broad-band accelerometer also measures large body movements and subtle physiological activities/vibrations. We find that the combined data processed by a 2D-like sequential feature extractor with fully connected neurons facilitates the classification of various motion/speech features at a high accuracy of over 90%, which adapts to the data with noise from motion artifacts or the data from new human subjects. The resulting standalone stretchable device with wireless monitoring and machine learning-based processing capabilities paves the way to design and apply wearable skin-interfaced systems for the remote monitoring and treatment evaluation of various diseases.

Abstract
BACKGROUND The amide proton transfer-weighted (APTw) imaging for kidney diseases is important. However, the breathing patterns on APTw imaging remains unexplored. PURPOSE This study aimed to investigate the effects of intermittent breath-hold (IBH) and free breathing (FB) on renal 3D-APTw imaging. STUDY TYPE Healthy volunteers were enrolled prospectively, and renal clear cell carcinoma (RCCC) patients were included retrospectively. POPULATION 58 healthy volunteers and 10 RCCC patients. FIELD STRENGTH/SEQUENCE 3-T, turbo spin echo, and fast field echo. ASSESSMENT 3D-APTw imaging was scanned using the IBH and FB methods in volunteers and using the IBH method in RCCC patients. The image quality was evaluated by three observers according to the 5-point Likert scale. Optimal images rated at three points or higher were used to measure the APT values. STATISTICAL ANALYSIS The measurement repeatability was assessed using the intraclass correlation coefficient (ICC) and the Bland-Altman plot. The APT values were analyzed using McNemar's test, one-way analysis of variance, and t test. RESULTS 50 healthy volunteers and 8 RCCC patients were enrolled. Renal 3D-APTw imaging using the IBH method revealed a higher success rate (88% vs 78%). The ICCs were excellent in the IBH group (ICCs > 0.74) and were good in the FB group (ICCs < 0.74). No significant differences in the APT values among various zones using the IBH (P = 0.263) or FB method (P = 0.506). The mean APT value using the IBH method (2.091% ± 0.388%) was slightly lower than the FB method (2.176% ± 0.292%), but no significant difference (P = 0.233). The APT value of RCCC (4.832% ± 1.361%) was considerably higher than normal renal using the IBH method. CONCLUSIONS The study demonstrated that the IBH method substantially increased the image quality of renal 3D-APTw imaging. Furthermore, APT values may vary between normal and tumor tissues. LEVEL OF EVIDENCE 2 TECHNICAL EFFICACY: Stage 2.

Abstract
Objective: To investigate the arthroscopic temporomandibular joint disc reduction on the outcome of orthodontic patients with anterior disc displacement without reduction. Methods: From January 2012 to December 2021, forty treated orthodontic patients with anterior disc displacement without reduction (unilateral/bilateral) and no obvious articular cartilage absorption were selected from Department of Orthodontics, Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine. The patients were (17.5±3.8) years old (12-25 years old), including 8 males and 32 females. Twenty patients who had completed arthroscopic temporomandibular joint disc reduction were included in the control group, and twenty patients with untreated temporomandibular joint disc were included in the experimental group. Model measurement (including overjet, etc.), cephalometric analysis (including ANB angle, which was formed by subspinale, nasion and supramental, etc.) and temporomandibular joint magnetic resonance imaging (including measurement of the condyle height of the displacement sides) were used to compare the difference of two groups. Objective grading system was used to evaluate the efficacy of orthodontic treatment. Results: The overjet of the experimental group and the control group after orthodontic treatment was (2.19±0.76) and (1.92±0.94) mm, respectively. Both two groups achieved ideal overjet with no statistical difference (t=1.02, P=0.314). The ANB angle difference before and after treatment in the control group (-1.97°±2.87°) was greater than that in the experimental group (0.09°±1.82°), and the difference was statistically significant (t=2.72, P=0.010). The variation of condyle height before and after treatment was (0.30±1.11) mm in the experimental group and (0.82±1.25) mm in the control group, with no statistical significance (t=1.80, P=0.076). The post-treatment objective grading system scores of the experimental group and the control group were 21.00 (16.00, 24.00) and 21.00 (17.00, 25.00), respectively, which had no statistical difference (U=0.24, P=0.808). Conclusions: In orthodontic patients with anterior disc displacement without reduction and no obvious articular cartilage absorption, whether displaced discs are repositioned after arthroscopic surgery has no significant effect on the orthodontic treatment outcome.

Abstract
OBJECTIVE This study aimed to assess the application value of distal femur 90° locking plate fixation for supracondylar femoral fractures (SFF) in children. PATIENTS AND METHODS A total of 100 SFF children with or without diabetes who were enrolled in our hospital from January 2018 to January 2020 were randomized into a control group and a study group by the random number table method. The study group received distal femur locking plate fixation, and the control group adopted Kirschner wire (K wire) internal fixation. The primary outcomes of the two groups of children and the secondary outcomes of the diabetic patients were compared. RESULTS The fracture union rate of the study group was significantly higher than that of the control group at 12 weeks, 16 weeks, 20 weeks and 24 weeks after the operation (p<0.05), while the rate showed no significant difference between the two groups at 28 weeks after the operation (p>0.05). The two groups showed similar operation time, intraoperative blood loss, intraoperative fluoroscopy time, and hospital stay (p>0.05). The study group yielded a more favorable outcome with regard to the Harris-Hip-Score (HHS) scores, HHS excellent-and-good rate, and Flynn scores satisfaction rate than the control group (p<0.001 or 0.05). The intracavitary pressure of the knee joint of the two groups presented a gradual decline with time, with remarkably lower results in the study group compared with the control group at 8 weeks and 16 weeks after the surgery (p<0.05), and differences at 24 weeks after the surgery did not come up to the statistical standard (p>0.05). Patients experienced fewer postoperative complications after locking plate fixation, as compared to those who received K wire treatment (p<0.05). Compared with the control group, the fracture union rate of diabetic children in the study group was significantly higher at 12 weeks, 16 weeks, and 20 weeks after surgery, respectively (p<0.05), while there was no significant difference between the two groups at 24 weeks and 28 weeks (p>0.05). CONCLUSIONS The distal femur 90° locking plate fixation for diabetic children with SFF obviates the need for plate shaping and ensures firm fixation, with biomechanical design, promising efficacy, and few complications. The distal femur 90° locking plate fixation has better efficacy for children with diabetes. It shows great potential as the treatment of choice for diabetic children with SFF.

Abstract
BACKGROUND Previous studies have shown that patients with chronic obstructive pulmonary disease (COPD) of severe or very severe airflow limitation have a reduced pectoralis muscle area (PMA), which is associated with mortality. However, whether patients with COPD of mild or moderate airflow limitation also have a reduced PMA remains unclear. Additionally, limited evidence is available regarding the associations between PMA and respiratory symptoms, lung function, computed tomography (CT) imaging, lung function decline, and exacerbations. Therefore, we conducted this study to evaluate the presence of PMA reduction in COPD and to clarify its associations with the referred variables. METHODS This study was based on the subjects enrolled from July 2019 to December 2020 in the Early Chronic Obstructive Pulmonary Disease (ECOPD) study. Data including questionnaire, lung function, and CT imaging were collected. The PMA was quantified on full-inspiratory CT at the aortic arch level using predefined -50 and 90 Hounsfield unit attenuation ranges. Multivariate linear regression analyses were performed to assess the association between the PMA and airflow limitation severity, respiratory symptoms, lung function, emphysema, air trapping, and the annual decline in lung function. Cox proportional hazards analysis and Poisson regression analysis were used to evaluate the PMA and exacerbations after adjustment. RESULTS We included 1352 subjects at baseline (667 with normal spirometry, 685 with spirometry-defined COPD). The PMA was monotonically lower with progressive airflow limitation severity of COPD after adjusting for confounders (vs. normal spirometry; Global Initiative for Chronic Obstructive Lung Disease [GOLD] 1: β=-1.27, P=0.028; GOLD 2: β=-2.29, P<0.001; GOLD 3: β=-4.88, P<0.001; GOLD 4: β=-6.47, P=0.014). The PMA was negatively associated with the modified British Medical Research Council dyspnea scale (β=-0.005, P=0.026), COPD Assessment Test score (β=-0.06, P=0.001), emphysema (β=-0.07, P<0.001), and air trapping (β=-0.24, P<0.001) after adjustment. The PMA was positively associated with lung function (all P<0.05). Similar associations were discovered for the pectoralis major muscle area and pectoralis minor muscle area. After the 1-year follow-up, the PMA was associated with the annual decline in the post-bronchodilator forced expiratory volume in 1 s percent of predicted value (β=0.022, P=0.002) but not with the annual rate of exacerbations or the time to first exacerbation. CONCLUSION Patients with mild or moderate airflow limitation exhibit a reduced PMA. The PMA is associated with airflow limitation severity, respiratory symptoms, lung function, emphysema, and air trapping, suggesting that PMA measurement can assist with COPD assessment.

Abstract
Pulmonary fibrosis is the end-stage pathological change of lung diseases, which seriously affects the respiratory function of human body. A large number of studies at home and abroad have confirmed that epithelial-mesenchymal transition (EMT) is an important intermediate stage in the development of pulmonary fibrosis. Inhibition of multiple pathways upstream and downstream of EMT, such as the classical Smads pathway and non-Smads pathway of TGF-1 can effectively inhibit the process of EMT and alleviate pulmonary fibrosis. This article will review the main conclusions of the mechanism of action of EMT as a target to improve the pathology of pulmonary fibrosis so far, and provide a theoretical basis and research direction for further research and development of anti-pulmonary fibrosis drugs.

Abstract
Surgical treatment of tumours in the anterior mandible and surrounding tissues may result in defects which can be restored by a fibula free flap. The upper airway may change during this process. The purpose of this retrospective study was to evaluate upper airway changes after fibula free flap reconstruction. A total of 37 patients who underwent anterior mandibulectomy and fibula free flap reconstruction between 2012 and 2020 were recruited. Patients with benign and malignant tumours involving the anterior mandible were included. Spiral computed tomography was performed 1 week preoperatively, 1 week postoperatively, and at> 1 year (range 12-23 months) after surgery. Cross-sectional areas and volumes of the upper airway were measured. Data were analysed by two-way analysis of variance. The upper airway in the malignant tumour group showed an increasing trend, especially at the soft palate and tongue base levels (P < 0.01). In the benign tumour group, the upper airway showed no significant changes. The location of the minimum cross-sectional area moved downwards in both groups, and the area increased in the malignant tumour group during long-term follow-up. Upper airway obstruction is less likely to occur in the long term after surgical resection of anterior mandible malignancies and fibula free flap reconstruction.

Abstract
Objective: To summarize the genetics and clinical phenotypes of epilepsy children with 2q24.3 microdeletion. Methods: All the patients with 2q24.3 microdeletion were retrospectively collected at the Pediatric Department of Peking University First Hospital from March 2017 to July 2022. The features of clinical manifestations, electroencephalogram (EEG), and neuroimaging were analyzed. Results: There were 13 patients with 2q24.3 microdeletion were included. All 13 patients had de novo copy number variation (CNV) with a deletion size ranged 0.18-7.31 Mb. The main pathogenic genes in the region were SCN3A, SCN2A, TTC21B, SCN1A and SCN9A genes. Among the 13 patients, 7 were boys, and 6 were girls. The onset age of epilepsy was 3.3(2.5, 6.0) months. Multiple seizure types were observed, including focal seizures in 13 patients, generalized tonic-clonic seizures (GTCS) in 6 patients, myoclonic seizures in 3 patients, epileptic spasm in 2 patients, and tonic seizures in 2 patients. Seizures were fever sensitivity in 9 patients. Status epilepticus was observed in 6 patients. One case had normal mental motor development and 12 cases had different degrees of developmental delay. Six patients had craniofacial abnormality, 1 had six-finger deformity of the right thumb, and 1 had multiple system abnormalities. EEG showed focal discharge in 3 cases, multifocal discharges in 5 cases, multifocal and generalized discharges in 1 case. Brain magnetic resonance imaging (MRI) showed enlargement of subarachnoid spaces in the frontal and temporal region in 4 patients, enlargement of lateral ventricle in 4 patients and delayed myelination of white matter in 1 patient. Dravet syndrome was diagnosed in 5 cases. The age at the last follow-up were 2.5(1.4,5.5) years, 1 patient was seizure free longer than 1 year, and 12 patients still had seizures. Conclusions: The epilepsy associated with 2q24.3 microdeletion is mainly induced by the deletion of SCN3A, SCN2A and SCN1A genes. The seizure onset age of 2q24.3 microdeletion related epilepsy was in infancy. Multiple seizure types are observed and the common seizure types include focal seizures and GTCS. Most patients have fever sensitivity and status epilepticus. Most patients have developmental delay. The phenotype of patients with deletion of SCN3A and SCN2A gene is more severe than that of patients with deletion of SCN1A gene only.

Abstract
Objective: To investigate whether pre-lingual deafness adult caused by inadequate auditory compensation in childhood can benefit from cochlear implants and the related influencing factors. Methods: A total of 26 prelingual deafness as experimental group [11 males and 15 females, the age of operation was (24.5±5.7) years] and 13 postlingual deafness as control group [5 males and 8 females, the age at the time of operation was (42.2±11.4) years] were recruited. Objective assessment included hearing threshold and speech recognition rate tests while wearing cochlear implants. Subjective assessment used Nijmegen Cochlear Implant Questionnaire to assess hearing-related quality of life of subjects. The changes of hearing ability in the prelingual deafness group before and after operation and the differences with the postlingual deafness group were compared, and the correlation between speech recognition ability and the age diagnosed as severe or profound deafness, the age of hearing aid invalid, and duration of wearing cochlear implant were analyzed as factor indicators. All statistical results were analyzed by SAS 9.4 software. Results: In terms of objective indicators, the speech recognition rate of pre-lingual deafness was significantly lower than that of post-lingual deafness [(35.4±28.0)% vs (80.9±8.0)%,t=7.67, P<0.001], while there was no statistical difference in hearing threshold between the two groups [(34.8±4.0) dB HL vs (33.1±3.7) dB HL, t=1.30, P>0.05]. The indicators in the subjective questionnaire showed that the prelingual deafness group was only weaker in advanced sound perception, confidence and total mean score than the post-lingual deafness group (P<0.05), and there was no significant difference in other aspects(P>0.05), meanwhile, all indicators of the prelingual deafness group were significantly improved compared with the preoperative level (P<0.001). There was a moderate positive correlation between the hearing quality and the speech recognition rate in the prelingual deafness group(r=0.51, P=0.008). The regression analysis showed that the invalid age of hearing aid was the exact influencing factor of speech recognition rate. Conclusions: Certain prelingual deaf adults can adapt to cochlear implants and obtain different degrees of auditory assistance. Compared with the improvement of objective auditory ability assessment, the patient who received cochlear implantation gain more improvement in auditory related quality of life subjectively. The ineffective age of preoperative hearing aid is an important factor, which needs to be aroused sufficient preoperative attention.

Abstract
Laguerre-Gaussian (LG) modes can be converted from fundamental Gaussian mode by using phase optical elements such as spiral phase plates (SPP), but the conversion efficiency is strongly reduced in high charge plates because of the transverse intensity deviation. In this paper, a three-step scheme is proposed to dramatically improve the conversion efficiency. First, a fundamental Gaussian beam is converted to a 1st-order LG beam via a 1st-order SPP and a spatial filtering system. Then, by using a periscopic axicon mirror (PAM), the lst-order LG beam is transformed into an annular beam with larger beam radius. Finally, by using a second high-order SPP, this intensity-matched ring beam can be effectively converted to a high-charge LG0l beam. Through optimization of the PAM's parameter, the total conversion efficiency from fundamental Gaussian beam to LG0l mode as high as 91.85% is obtained, which is much higher than the case without PAM. Numerical simulations are carried out by the particle-in-cell (PIC) code EPOCH to verify the effectiveness of the scheme.

Abstract
Objective: To explore the effects of maternal pre-pregnancy body mass index (BMI) and gestational weight gain and its subtypes on the risk of preeclampsia. Methods: Pregnant women delivered in the Department of Obstetrics and Gynecology of the First Affiliated Hospital of Shanxi Medical University from March 2012 to September 2016 were selected as the research subjects. According to the inclusion and exclusion criteria, 9 274 pregnant women were included. 901 preeclampsia pregnant women were selected as the case group, and 8 373 non-preeclampsia pregnant women were selected as the control group. General demographic characteristics, pre-pregnancy weight, height, lifestyle during pregnancy, reproductive history, and disease history of pregnant women were collected, and pre-pregnancy BMI and gestational weight gain were calculated. Unconditional logistic regression was used to analyze the relationship between pre-pregnancy BMI and weight gain during pregnancy and PE and its clinical subtypes. Results: Among the 901 preeclampsia after inclusion and exclusion, 401 cases were diagnosed as early-onset PE (EOPE), 500 cases were late-onset PE (LOPE), 178 cases were Mild PE (MPE), and 723 cases were severe PE (SPE). There were statistically significant differences between PE and non-PE pregnant women in terms of maternal age, residence, parity, family history of gestational diabetes and hypertension (P<0.05). After adjusting for the above factors, the logistic regression analysis results showed that pre-pregnancy BMI<18.5 kg/m2 and inadequate gestational weight gain were protective factors for PE (OR=0.74, 95%CI: 0.56-0.98; OR=0.78, 95%CI: 0.62-0.99), while pre-pregnancy BMI≥24.0 kg/m2 and excessive gestational weight gain were risk factors for PE (OR=1.82, 95%CI: 1.54-2.14; OR=1.82, 95%CI: 1.54-2.15). After subtype analysis on PE, the results showed that pre-pregnancy BMI<18.5 kg/m2 was a protective factor for EOPE and MPE (OR=0.52, 95%CI: 0.32-0.83; OR=0.47, 95%CI: 0.23-0.97), while pre-pregnancy BMI≥24.0 kg/m2 and excessive gestational weight gain were risk factors for clinical subtypes of PE. After stratification according to pre-pregnancy BMI, excessive gestational weight gain was the risk factor for PE (OR=1.86, 95%CI: 1.51-2.30; OR=1.90, 95%CI: 1.39-2.60) in pregnant women 18.5 kg/m2≤BMI<24.0 kg/m2 and ≥24.0 kg/m2. Inadequate gestational weight gain (OR=0.55, 95%CI: 0.34-0.89) was a protective factor for PE in pregnant women with pre-pregnancy BMI≥24.0 kg/m2. Excessive gestational weight gain (OR=4.05, 95%CI: 1.20-13.69) was a risk factor for EOPE in pregnant women with pre-pregnancy BMI<18.5 kg/m2. Excessive gestational weight gain was a risk factor for the clinical subtype of PE in pregnant women 18.5 kg/m2≤BMI<24.0 kg/m2 before pregnancy. Inadequate gestational weight gain was a protective factor for EOPE and MPE (OR=0.39, 95%CI: 0.19-0.80; OR=0.29, 95%CI: 0.11-0.77) in pregnant women with pre-pregnancy BMI≥24.0 kg/m2. Excessive weight gain was a risk factor for EOPE, LOPE and SPE (OR=1.60, 95%CI: 1.06-2.42;OR=2.20, 95%CI: 1.44-3.37;OR=2.28, 95%CI: 1.58-3.29). Conclusions: Pre-pregnancy BMI and gestational weight gain affect the risk of preeclampsia and its clinical subtypes. In contrast, the influence of gestational weight gain on preeclampsia varies among different pre-pregnancy BMI groups. Therefore, it is recommended to pay attention to the changes in pre-pregnancy BMI and gestational weight gain simultaneously to reduce preeclampsia.

Abstract
Objective: To determinate the range of quantitative myocardial perfusion parameters (MBF, MBV) in subjects without coronary artery lesions by dynamic computed tomography myocardial perfusion imaging (CTP). Methods: Subjects with occasional chest tightness or family history of coronary artery disease coming to Fuwai Hospital underwent coronary computed tomography angiography (CCTA) were prospectively enrolled. A total of 34 subjects [mean age (50±7) years, range from 33 to 65 years; 15 male and 19 female] were enrolled. Coronary lesions were not confirmed in any subjects using CCTA and volunteered for stress and rest dynamic CTP examination. MBF and MBV values were calculated in each myocardial segment using a 17-segment model. The global ranges of MBF and MBV were analyzed, and the gender variability and regional variability were compared. Results: The mean global MBF and MBV at rest and under stress were (115.5±27.4) ml·100 g-1·min-1, (212.8±40.8) ml·100 g-1·min-1 and (17.6±4.0) ml/100 g, (25.8±4.6) ml/100 g, respectively. The absolute and resolute reserves of MBF and MBV [(102.8±41.5) ml·100 g-1·min-1, 107.7%±52.5%; (9.3±5.2) ml/100 g, 62.1%±47.4%] were highest in the right coronary artery territory, but without any significant differences. The stress MBF and absolute reserve of MBF in females were higher than those of males [(228.6±39.9) ml·100 g-1·min-1, (113.3±46.2) ml·100 g-1·min-1; (192.8±33.4) ml·100 g-1·min-1, (77.0±41.2) ml·100 g-1·min-1] (both P<0.05). The MBF resolute reserve, rest MBV, stress MBV and MBV absolute and resolute reserves were higher in females, but without significant differences (all P>0.05). Conclusion: The mean global MBF and MBV at rest and under stress were (115.5±27.4) ml·100 g-1·min-1, (212.8±40.8) ml·100 g-1·min-1 and (17.6±4.0) ml/100 g, (25.8±4.6) ml/100 g. The MBF under stress perfusion and MBF absolute reserve of females are higher than those of males.

Abstract
Intestinal obstruction is one of the most common diseases in abdominal surgery, and its prevention and treatment is a clinical difficulty. Although surgical operation can solve the symptoms of obstruction, there are many postoperative complications, and it is easy to develop re-obstruction due to postoperative abdominal adhesion. The internal fixation of small intestine with obstruction catheter provides a new idea for the prevention of postoperative adhesive bowel obstruction. The use of transanal ileus catheter provides the possibility of direct intestinal anastomosis after resection of malignant obstruction in the left hemicolon and can reduce the incidence of postoperative complications. However, sufficient attention should be paid to the related complications, and prevention and treatment should be planned. It is important to note that the use of obstruction catheter is only one of the conservative treatments for bowel obstruction, and it is not a complete replacement of surgery. Surgical treatment should still be considered, if the catheter fails to significantly move, if the obstructive symptoms do not significantly improve 5 days after catheterization.

Abstract
OBJECTIVE To investigate the correlation of baseline serum 25(OH) D level with the risk of type 2 diabetes mellitus (T2DM) and blood glucose control in diabetic patients among the middle-aged and elderly individuals in Chengguan District of Lanzhou, Gansu Province. OBJECTIVE Residents aged 40 to 75 years in Lanzhou were selected from the "REACTION" study conducted in 2011 and had been followed up since 2014. A total of 5044 subjects with complete data from the two surveys were analyzed. Participants were divided into Q1, Q2, Q3, and Q4 subgroups based on quartiles of serum 25(OH)D level for comparison of the incidence of T2DM and blood glucose control. OBJECTIVE Baseline 25(OH)D level was not found to correlate with FPG, 2h-PG or HbA1c levels among the residents (P>0.05). The participants were followed up for a mean of 3.4±0.6 years, and compared with those in Q1 group, the participants in Q2, Q3 and Q4 groups did not show significantly lowered risk of prediabetes or diabetes regardless of glucose tolerance status. Among the patients with T2DM, the compliance rate of glycemic control after the follow-up was significantly higher than that before the follow-up (63.4% vs 60.6%), and the levels of HbA1c, FPG, and 2h-PG decreased obviously after the follow-up. But compared with Q1 group, Q2, Q3 and Q4 groups showed no significant changes in glycemic control compliance rate or levels of HbA1c, FPG and 2h-PG after the follow-up (P>0.05). OBJECTIVE There is no evidence that baseline 25(OH)D levels are associated with the risk of diabetes and blood glucose control in patients with T2DM.

Abstract
OBJECTIVE To investigate the correlations of Helicobacter pylori (HP) with liver function, inflammatory factors and serum levels of forkhead box P3 (FoxP3) and retinoic acid receptor-related orphan receptor gamma-t (RORγt) in patients with hepatitis B cirrhosis (HBC). PATIENTS AND METHODS A total of 60 HBC patients were divided into HBC group (n=30) and HP-infected HBC group (HP&HBC group, n=30). QRT-PCR was conducted to determine the messenger ribonucleic acid (mRNA) levels of FoxP3 and RORγt in serum samples. ELISA was applied to measure the levels of relevant inflammatory factors. Besides, immunohistochemical staining was conducted to detect positive expressions of FoxP3 and RORγt in liver tissues of patients in the two groups. RESULTS No significant differences in gender, drinking, smoking, diabetes and age were found between HBC group and HP&HBC group (p>0.05). Globulin and albumin levels were comparable between the two groups (p>0.05). Liver function indexes, including ALT, AST and TBIL were higher in HP&HBC group than those in HBC group (p<0.05). The HBV-DNA level was lower in HBC group in comparison with that in HP&HBC group. The interferon-gamma (IFN-γ) level was remarkably higher in HBC group than that in HP&HBC group (p<0.01), and the levels of interleukin (IL)-6, IL-10, IL-17 and transforming growth factor (TGF)-β1 were notably lower in HBC group in comparison with those in HP&HBC group (p<0.01). Additionally, the mRNA levels of FoxP3 and RORγt in HBC group were distinctly lower than those in HP&HBC group (p<0.01). The mRNA levels of FoxP3 and RORγt were positively related to those of IL-6, IL-10, IL-17, and TGF-β1, and negatively associated with IFN-γ level. Immunohistochemical results indicated that positive expression rates of FoxP3 and RORγt in the liver tissues were approximately 50% in HP&HBC group and B. Zhao, Q.-J. Sheng, Y. Qin, X.-L. Wang, H. Zhao, N. Zhaowere 15% in HBC group, and the difference was statistically significant (p<0.05). CONCLUSIONS Expression levels of FoxP3 and RORγt in serum and liver tissues are elevated in HP-infected HBC patients, and inflammatory factors are correlated with their expressions, suggesting the aggravated liver damage.

Abstract
Objective: To investigate the status and influencing factors of skin cleaning outside wound (hereinafter referred to as skin) in adult trauma patients. Methods: A multicenter cross-sectional investigation was conducted. From September 1 to 30, 2020, a total of 952 adult trauma patients who met the inclusion criteria were admitted to wound care clinics or trauma surgery wards of 13 military or local Grade Ⅲ Level A hospitals, including the General Hospital of the Eastern Theater Command of People's Liberation Army and the Army Medical Center, etc. A self-designed questionnaire on cleaning status of skin in trauma patients was released through the "questionnaire star" website to investigate basic information such as gender, age, education level, living status, and self-care ability, trauma information such as cause of injury, wound duration, trauma site, trauma depth, wound pain, wound peculiar smell, and wound cleaning solution, and skin cleaning status after injury such as whether to clean or not, cleaning method, cleaning frequency, cleaning duration in each time, or reasons for not cleaning. The patients who cleaned skin regularly after injury were included in cleaning group, and the other patients were included in no cleaning group. The basic information, trauma information, and skin cleaning status after injury of patients in 2 groups were investigated. Data were statistically analyzed with chi-square test, and binary multivariate logistic regression analysis was performed on indicators with statistically significant differences between the two groups to screen the independent influencing factors of skin cleaning in trauma patients. Results: A total of 952 questionnaires were received, and the recovery rate was 100%. Three invalid questionnaires were eliminated, and 949 valid questionnaires were obtained, with an effective rate of 99.68%. In 949 patients, there were 461 (48.6%) males and 488 (51.4%) females, aged 18-100 (50±18) years. Most patients were less than 60 years old, lived with their families, and could take care of themselves completely. Nearly half of the patients were with junior high school or below education level. The main causes of injury were sharp cutting injury and falling injury, the wound duration was 2-365 days, most of the injured parts were limbs and trunk, the wound depth was mostly full-thickness injury, and most patients had wound-related pain and no peculiar smell and used 5 g/L iodophor to clean the wound. Totally 684 (72.1%) patients cleaned their skin after injury, mainly by scrubbing with warm water, the cleaning frequency was mainly once or twice a week, and the cleaning time was mainly 10 or 15 min for each time. Totally 265 (27.9%) patients didn't clean their skin after injury, and the main causes for not cleaning were following the doctor's advice, followed by worrying about wound infection and loss of self-care ability. There were significantly statistical differences in constituent ratios of education level, self-care ability, cause of injury, wound pain, and wound peculiar smell of patients in 2 groups (χ2=12.365, 24.519, 22.820, 9.572, 92.342, P<0.01). Education level, self-care ability, cause of injury, wound pain, and wound peculiar smell were potential influencing factors of skin cleaning in patients. Binary multivariate logistic regression analysis showed that self-care ability, wound pain, and wound peculiar smell were independent influencing factors of skin cleaning in patients (odds ratio=1.51, 0.52, 3.72, 95% confidence interval=1.08-2.12, 0.42-0.89, 2.66-5.22, P<0.05 or P<0.01). Conclusions: Self-care ability, wound pain, and wound peculiar smell are independent influencing factors of skin cleaning in adult trauma patients.

Abstract
Chronic obstructive pulmonary disease (COPD) represents a chronic inflammatory disorder of the airways induced mainly by cigarette smoking. In the current study, cigarette smoke extract (CSE) was used to develop an in vitro COPD model using human bronchial epithelium (HBE) cells to expound the possible role of microRNA-29b (miR-29b) in COPD. Firstly, miR-29b and interleukin (IL)-22 expression was assessed in serum of 20 healthy non-smokers, 20 healthy smokers and 20 COPD patients as well as CSE-treated HBE cells. Then, miR-29b and IL-22 expression was altered to evaluate their functions in Th17/Treg ratio. miR-29b inhibited Th17/Treg ratio and levels of IL-22; whereas overexpression of IL-22 reversed these trends. Moreover, rescue experiments found that IL-22 neutralized the repressive effects of miR-29b on Th17/Treg ratio and inflammatory response. Finally, we found that miR-29b blocked the JAK/STAT3 pathway in CSE-treated HBE cells. These data highlighted that miR-29bs modulated Th17/Treg imbalance in CSE-induced experimental COPD through inhibition of IL-22-dependent JAK/STAT3 pathway.

Here, we reported the molecular mechanisms by which lncRNA APPAT regulated in the progression of breast cancer. MATERIALS AND METHODS QPCR was used to inspect the expression of lncRNA APPAT and miR-328a in breast cancer cell lines. Luciferase reporter assay confirmed the direct target effect of APPAT and miR-328a. Western blot was used to check Pkp1 protein expression in breast cancer cell lines. RESULTS The expressions of lncRNA APPAT, Pkp1 protein levels and miR-328a were commonly expressed in breast cancer cells. The inhibition of lncRNA APPAT expression repressed cell proliferation, migration and invasion in breast cancer and reverse results were found after lncRNA APPAT overexpressing. Mechanistically, the binding targets of lncRNA APPAT vs. miR-328a and Pkp1 vs. miR-328a were checked in breast cancer. Meanwhile, miR-328a silencing enhanced the proliferation, migration and invasion of breast cancer cells. Moreover, the effect caused by Pkp1 silencing on cell proliferation, migration and invasion was reversed by miR-328a inhibitor in MCF-7 and BT594 cells. Additionally, Pkp1 knockout reversed the effect of cell proliferation, migration and invasion triggered by APPAT elevated. Taken together, these results showed miR-328a as a downstream target of lncRNA APPAT linking lncRNA APPAT to Pkp1. CONCLUSIONS LncRNA APPAT regulated the proliferation, migration, invasion of breast cancer by regulating miR-328a/Pkp1 signaling pathway, providing a novel possible strategy for the treatment of breast cancer.

Abstract
Monitoring biophysical signals such as body or organ movements and other physical phenomena is necessary for patient rehabilitation. However, stretchable flexible pressure sensors with high sensitivity and a broad range that can meet these requirements are still lacking. Herein, we successfully monitored various vital biophysical features and implemented in-sensor dynamic deep learning for knee rehabilitation using an ultrabroad linear range and high-sensitivity stretchable iontronic pressure sensor (SIPS). We optimized the topological structure and material composition of the electrode to build a fully stretching on-skin sensor. The high sensitivity (12.43 kPa-1), ultrabroad linear sensing range (1 MPa), high pressure resolution (6.4 Pa), long-term durability (no decay after 12000 cycles), and excellent stretchability (up to 20%) allow the sensor to maintain operating stability, even in emergency cases with a high sudden impact force (near 1 MPa) applied to the sensor. As a practical demonstration, the SIPS can positively track biophysical signals such as pulse waves, muscle movements, and plantar pressure. Importantly, with the help of a neuro-inspired fully convolutional network algorithm, the SIPS can accurately predict knee joint postures for better rehabilitation after orthopedic surgery. Our SIPS has potential as a promising candidate for wearable electronics and artificial intelligent medical engineering owing to its unique high signal-to-noise ratio and ultrabroad linear range. An ultrabroad-linear range (1 MPa) iontronic pressure sensor with superior sensitivity (12.43 kPa-1) and stretchability (up to 20%) was proposed for biophysical monitoring and deep learning-based knee-rehabilitation training.

Abstract
Hepatic inflammatory response is a risk factor for liver cancer initiation and progression. Interleukin (IL)-35 is the newest member of the IL-12 cytokine family, and has been reported to play an essential role in the immunosuppressive liver microenvironment. Herein we focus on the expression profiles of IL-35 in hepatocellular carcinoma (HCC) and effects on local immune status. HCC transcriptome array data were downloaded from Gene Expression Omnibus (GEO). Analysis was performed by BRB-Array Tools and Ingenuity Pathway Analysis (IPA) software. Serum IL-35 level was detected by AimPlet bead-based immunoassay. In-situ IL-35 detection was performed by immunohistochemical staining and Western blot. The n-vitro effect of IL-35 on CD4+ or CD8+ T cell function was detected by flow cytometry. Our results showed that there were large amounts of IL-35 expressed in HCC serum and tumor tissues. IL-35 expression affects the transcript of thousands of genes, most differentially expressed genes (DEGs), in tumor tissues correlated with T cell immunity. The IL-35 high-expression group exhibited enhancement of regulatory T cells (Tregs ) and impairment of cytolytic T cells. In-vitro experiments proved that exogenous IL-35 stimulated the expression of programmed cell death 1 (PD-1) and lymphocyte activation gene-3 (LAG3) in CD4+ and CD8+ T cells. In addition, the stimulating effect was time-dependent. Furthermore, IL-35 inhibited interferon (IFN)-γ secretion by CD4+ and CD8+ T cells. Elevated IL-35 had an immune suppressive role in HCC tumor microenvironments through affecting inhibitor receptor expression and cytokine secretion of CD4+ and CD8+ T cells. Dissection of the precise targets and underlying molecular mechanisms would mean alternative treatments for HCC patients.

Abstract
Diabetic kidney disease (DKD) is a leading cause of end-stage renal disease worldwide and is associated with increased morbidity and mortality in patients with both type 1 and type 2 diabetes. Early treatment of DKD can prevent or slow its progression. Some studies suggest that traditional risk factors such as albuminuria do not effectively predict DKD progression, and other predictors have yet to be characterized and validated. Therefore, there is an urgent need to identify sensitive and easily detectable biomarkers to monitor the decline in renal function. MicroRNAs (miRNAs) have recently emerged as important regulators that are ubiquitous in human tissues and bodily fluids, numerous diseases, including early DKD. Recent developments have revealed that miRNAs-mediated post-transcriptional regulation of gene expression represents an integral part of the autophagy regulatory network. In this review, we explored the utility of miRNAs as biomarkers for the early detection and progression of DKD. We also examined some of the molecular mechanisms by which miRNAs manipulate the autophagic machinery to maintain cellular homeostasis during DKD. A better understanding of the interaction between miRNAs and autophagy may ultimately benefit future DKD diagnosis and therapy.

Abstract
Anti-interleukin 5 (IL-5) and anti-IL-5 receptor α monoclonal antibodies markedly decrease airway and peripheral blood eosinophil numbers and are thus highly effective in reducing asthma exacerbations. Nonetheless, these biologics do not completely resolve exacerbations. There is very little information on the cellular nature of exacerbations during treatment with biologics. Using illustrative clinical case scenarios, we highlight the importance of carefully characterizing asthmatics at the time of exacerbation and recognizing neutrophilic causes of exacerbations to ensure optimal management. While an eosinophilic exacerbation may improve with more corticosteroids or by switching to another anti-IL-5 monoclonal antibody, a noneosinophilic exacerbation will likely not. An infective exacerbation needs to be recognized, and the pathogen must be identified and treated with the appropriate antimicrobial agent.

Abstract
OBJECTIVE To explore the predictive value of carotid femoral artery pulse wave velocity (CF-PWV), carotid radial artery pulse wave velocity (CR-PWV), cardio-ankle vascular index (CAVI), and ankle brachial index (ABI) on coronary heart disease (CHD) and cerebral infarction (CI), and the preliminary validation of Beijing vascular health stratification (BVHS). METHODS Subjects with at least 2 in-patient records were included into the study between 2010 and 2017 from Vascular Medicine Center of Peking University Shougang Hospital. Subjects with CHD or CI, and without data of vascular function at baseline were excluded. Eventually, 467 subjects free of CHD [cohort 1, mean age: (63.4±12.3) years, female 42.2%] and 658 subjects free of CI [cohort 2, mean age: (64.3±12.2) years, female 48.7%] at baseline were included. The first in-patient records were as the baseline data, the second in-patient records were as a following-up data. Cox proportional hazard regression was used to establish the predictive models of CHD or CI derived from BVHS by multivariable-adjusted analysis. RESULTS The median follow-up time of cohort 1 and cohort 2 was 1.9 years and 2.1 years, respectively. During the follow-up, 164 first CHD events occurred in cohort 1 and 117 first CI events occurred in cohort 2. Four indicators were assessed as continuous variables simultaneously by multivariable-adjusted analysis. In cohort 1, CF-PWV, CR-PWV, ABI, and CAVI reached statistical significance in the multivariable-adjusted models (P<0.05). In cohort 2, only CAVI (P<0.05) was of statistical significance. In addition, the higher CF-PWV became a protector of CHD or CI (P<0.05). The prediction value of BVHS reached the statistical significance for CHD and CI in the unadjusted models (all P<0.05), however, BVHS could only predict the incidence of CHD (P<0.05), but not the incidence of CI (P>0.05) in the multivariable-adjusted models. CF-PWV, CR-PWV, ABI, and CAVI were associated factors of CHD independent of each other (P<0.05), only CAVI (P<0.05) was the risk factor of CI independent of the other three. CONCLUSION The different vascular indicators might have different effect on CHD or CI. CAVI might be a stable predictor of both CHD and CI. Higher baseline CF-PWV was not necessarily a risk factor of CHD or CI because of proper vascular health management. BVHS was a potential factor for the prediction of CHD, and further research is needed to explore the prediction value for CI.

Abstract
The last two decades have witnessed two large-scale pandemics caused by coronaviruses, including severe acute respiratory syndrome (SARS) and the Middle East respiratory syndrome (MERS). At the end of 2019, another novel coronavirus, designated as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), hit Wuhan, a city in the center of China, and subsequently spread rapidly to the whole world. Latest reports revealed that more than 800 thousand people in over 200 countries are involved in the epidemic disease by SARS-CoV-2. Due to the high mortality rate and the lack of optimum therapeutics, it is crucial to understand the biological characteristics of the virus and its possible pathogenesis to respond to the SARS-CoV-2. Rapid diagnostics and effective therapeutics are also important interventions for the management of infection control. However, the rapid evolution of SARS-CoV-2 exerted tremendous challenges on its diagnostics and therapeutics. Therefore, there is an urgent need to summarize the existing research results to guide decision-making on the prioritization of resources for research and development. In this review, we focus on our current understanding of epidemiology, pathogenesis, diagnostics and therapeutics of coronavirus disease 2019 (COVID-19).

Abstract
Objective: To investigate the antagonistic effect of diallyl sulfide (DAS) against peripheral nerve injury induced by n-hexane in rats. Methods: A total of 68 adult male Wistar rats were selected, among which 50 were randomly selected and divided into blank control group, DAS control group (100 mg/kg·bw) , n-hexane model group, low-dose DAS intervention group (50 mg/kg·bw) , and high-dose DAS intervention group (100 mg/kg·bw) . A rat model of peripheral nerve injury was established by n-hexane exposure, and the rats were treated with DAS at different doses. The changes in pyrrole adducts and behavior were observed, a metabolic analysis was performed for serum pyrrole adducts, and the intervention effect was evaluated. The remaining 18 rats were randomly assigned to the n-hexane model group, the low-dose DAS intervention group, and the high-dose DAS intervention group, with 6 rats in each group, as satellite groups used for the toxicokinetic analysis of serum pyrrole adducts. Results: Compared with the blank control group, the n-hexane model group and low-and high-dose DAS intervention groups had a significant reduction in body weight since week 2 (P<0.01) . Compared with the n-hexane model group at the end of the experiment at week 7, the high-dose DAS intervention group had a significantly higher body weight (P<0.05) , while there was no significant difference in body weight between the n-hexane model group and the low-dose DAS intervention group (P>0.05) . The n-hexane model group developed gait abnormality at week 2 of poisoning, while the low-and high-dose DAS intervention groups developed gait abnormality at weeks 3 and 5 of poisoning, respectively. At the end of the experiment, the n-hexane model group and the low-and high-dose DAS intervention groups had a significantly higher gait score than the blank control group (P<0.01) . At the end of the experiment, the n-hexane model group and the low-dose DAS intervention group had significantly shorter latency in rotarod test than the blank control group (P<0.01) , while there was no significant difference in latency between the DAS control group and the high-dose DAS intervention group (P>0.05) . Compared with the n-hexane model group, the low-and high-dose DAS intervention groups had a significant increase in latency in rotarod test (P<0.01) . Compared with blank control group, the n-hexane model group and the low-dose DAS intervention group had a significant increase in mean nerve conduction velocity (P<0.01) , while there was no significant difference between the blank control group and the DAS control group or high-dose DAS intervention group (P>0.05) , and compared with the n-hexane model group, the low-and high-dose DAS intervention groups had a significant increase in nerve conduction velocity (P<0.01) . Compared with the blank control group at the end of the experiment at week 7, the n-hexane model group and the low-and high-dose DAS intervention groups had significant increases in the concentration of pyrrole adducts in serum, urine, and hair (P<0.01) , while there was no significant difference between the blank control group and the DAS control group (P>0.05) , and the high-dose DAS intervention group had a significantly lower concentration of pyrrole adducts in serum, urine, and hair than the low-dose DAS intervention group (P<0.05) . Serum pyrrole adducts reached the peak level at 9-12 hours and then started to decrease. Compared with the n-hexane model group, the high-and low-dose DAS intervention groups had a significantly shorter half-life period of serum pyrrole adducts (P<0.01) . Compared with the n-hexane model group, the high-and low-dose DAS intervention groups had a significant reduction in the area under the curve of serum pyrrole adducts (P<0.05) . Conclusion: DAS can antagonize peripheral nerve injury induced by n-hexane.

Abstract
Chemically synthesized near-infrared to mid-infrared (IR) colloidal quantum dots (QDs) offer a promising platform for the realization of devices including emitters, detectors, security, and sensor systems. However, at longer wavelengths, the quantum yield of such QDs decreases as the radiative emission rate drops following Fermi's golden rule, while non-radiative recombination channels compete with light emission. Control over the radiative and non-radiative channels of the IR-emitting QDs is crucially important to improve the performance of IR-range devices. Here, we demonstrate strong enhancement of the spontaneous emission rate of near- to mid-IR HgTe QDs coupled to periodically arranged plasmonic nanoantennas, in the form of nanobumps, produced on the surface of glass-supported Au films via ablation-free direct femtosecond laser printing. The enhancement is achieved by simultaneous radiative coupling of the emission that spectrally matches the first-order lattice resonance of the arrays, as well as more efficient photoluminescence excitation provided by coupling of the pump radiation to the local surface plasmon resonances of the isolated nanoantennas. Moreover, coupling of the HgTe QDs to the lattice plasmons reduces the influence of non-radiative decay losses mediated by the formation of polarons formed between QD surface-trapped carriers and the IR absorption bands of dodecanethiol used as a ligand on the QDs, allowing us to improve the shape of the emission spectrum through a reduction in the spectral dip related to this ligand coupling. Considering the ease of the chemical synthesis and processing of the HgTe QDs combined with the scalability of the direct laser fabrication of nanoantennas with tailored plasmonic responses, our results provide an important step towards the design of IR-range devices for various applications.

Abstract
OBJECTIVE We conducted this study to analyze the EEG abnormalities of cognitive impairment and epileptic seizures in patients with epilepsy, as well as to investigate the application value of EEG in the diagnosis of epilepsy with cognitive impairment. PATIENTS AND METHODS 62 cases of patients that were admitted to our hospital for the first diagnosis as status epilepticus were selected. Of those, 20 cases were accompanied by cognitive impairment. The America Biology Graphene type 24 leads channel video EEG was applied to monitor staging, index, frequency, and distribution range of epileptic discharge. The revised Wechsler Adult Intelligence Scale-Revised in China (WAIS-RC) and Wechsler Memory Scale-Revised in China (WMS-RC) were adopted to test cognitive function. RESULTS The epileptic discharge index, discharge frequency and discharge distribution range of the conscious period, sleep I-II period and sleep III-IV period of epilepsy with the cognitive impairment group were evidently higher than those of epilepsy without cognitive impairment group. The differences were statistically significant (p<0.05). Intelligence Quotient (IQ) and Memory Quotient (MQ) level of the cognitive impairment group were the lowest in sleep III-IV period, with the next being the sleep I-II period; the highest was the conscious period, and the differences were statistically significant (p<0.05). With an increase of the epileptic discharge index, the discharge range, IQ and MQ level of cognitive impairment group decreased; differences were statistically significant (p<0.05). Therefore, the discharge index, frequency, and distribution range of epileptic discharge of epilepsy with cognitive impairment in different periods differed from epilepsy patients without cognitive impairment. According to the extent of cognitive impairment in different stages, discharge index, frequency, and distribution range were also different. CONCLUSIONS The 24 h video EEG, which was used to monitor epileptic discharge characteristics, has a great application value for early identification of epilepsy with cognitive impairment.

Abstract
OBJECTIVE This study sought to explore HuR, Thrombotic Thrombocytopenic Purpura (TTP), and microRNA 133b (miR-133b) expression levels in non-small cell lung cancer (NSCLC) patients and assess the relationship of expression with disease prognosis. PATIENTS AND METHODS One hundred and ten paraffin-embedded and 33 fresh flash-frozen NSCLC samples, together with matched tumor adjacent normal tissue controls, were collected from patients between January 2013 and July 2015 in Yidu Central Hospital of Weifang. Twenty-nine patients provided both paraffin-embedded and fresh frozen tissues. HuR and TTP protein expression levels were measured in 110 paraffin-embedded tumors and matched controls using immunohistochemistry, while miR-133b levels were measured using Real-time fluorescent quantitative PCR. RESULTS Follow-up parameters included treatment response, relapse events, post-relapse treatment, disease free survival (DFS), and overall survival (OS). HuR expression was significantly different between tumor and matched controls (p < 0.0001). Cytoplasmic expression levels of HuR and TTP correlated with pTNM staging (p < 0.05). No significant correlation was observed between HuR and TTP expression and other clinical pathological factors (gender, age, tumor size, pathological subtype, differentiation status, lymph node metastasis, distant metastasis, and tumor invasiveness). MiR-133b expression correlated with tumor size (p = 0.015) and differentiation status (p = 0.013) in paraffin-embedded sections, but was only correlated with pTNM staging (p = 0.032) in frozen tissue samples. No significant difference in DFS nor OS was observed between 68 HuR-positive and 42 HuR-negative patients (DFS, Log Rank p = 0.712; OS, Log Rank p = 0.220). However, DFS and OS were significantly different between miR-133b high-expression and low-expression patients (DFS, Log Rank p = 0.048 < 0.05; OS, Log Rank p = 0.025 < 0.05). This indicates that miR-133b levels may have prognostic value. CONCLUSIONS HuR expression was negatively correlated with TTP expression in NSCLC tissues. MiR-133b levels were downregulated in normal tissues compared to both paraffin and frozen tumor samples, and correlated with both HuR and TTP expression, which may affect the prognosis of NSCLC patients.

Abstract
Objective: To investigate the clinical efficacy of laparoscopic subtotal colonic bypass plus colostomy with antiperistaltic cecoproctostomy (SCBCAC) in the treatment of senile slow transit constipation. Methods: A retrospective cohort study was performed. Clinical data of 30 colonic slow transit constipation patients aged ≥70 years old undergoing laparoscopic SCBCAC from July 2012 to October 2016 (bypass plus colostomy group), and 28 patients undergoing laparoscopic subtotal colonic bypass with antiperistaltic cecoproctostomy (SCBAC) from February 2009 to June 2012 (bypass group) at our institute were collected. Efficacy was compared between the two procedures. Inclusion criteria: (1) meeting the Rome III diagnosis criteria for constipation; (2) confirmed diagnosis of slow transit constipation; (3) age ≥ 70 years old; (4) receiving non-surgical treatment for more than 5 years, and Wexner constipation score > 15; (5) follow-up for more than 2 years. Those with psychiatric symptoms or previous psychiatric history, obvious signs of outlet obstructive constipation, organic diseases of the colon and life-threatening cardiovascular diseases or cancer were excluded. In the bypass plus colostomy group, laparoscopy was performed via five trocars. The ileocecal junction and the ascending colon were mobilized and the ileocecal junction was pulled down to the pelvic inlet. The ascending colon was transected and the appendix was excised. The lateral peritoneum of the sigmoid colon and the rectal mesentery were dissected and the upper rectum was transected. The avil of a circular stapler was placed in the bottom of the cecum. The shaft of the stapler was placed in the rectum via the anal canal to complete end-to-side anastomosis (end rectum to lateral cecum). The end of the rectal-sigmoid colon was used for colostomy via an extraperitoneal approach to complete the operation. The following efficacy indexes were collected before surgery and 3, 6, 12, and 24 months after surgery: the number of daily bowel movements, the Wexner incontinence scale (WIS, 0-20, the lower the better), the Wexner constipation scale (WCS, 0-30, the lower the better), the gastrointestinal quality of life index (GIQLI, 0-144, the higher score, the better), abdominal pain intensity indicated by the numerical rating scale (NRS, 0-10, the lower score, the better), and the abdominal bloating score (ABS, 0-4, the lower score, the better). The complications defined as Clavien-Dindo class II or above were observed and recorded. Results: No significant differences in preoperative WCS, WIS, GIQLI, NRS, and ABS were observed between bypass plus colostomy group and bypass group (all P>0.05). All the patients successfully underwent laparoscopic surgery and no patient in either group experienced postoperative fecal incontinence. WCS and GIQLI were significantly improved (all P<0.001) at 3, 6, 12, and 24 months after surgery in both groups. At 12 months after surgery, the number of bowel movements was significantly less in bypass plus colostomy group than that in bypass group [(2.4±0.7) times vs. (3.4±1.2) times, t=4.048, P<0.001]. At 3, 6, 12 and 24 months after surgery, the improvement of GIQLI in bypass plus colostomy group was significantly better than that in bypass group (all P<0.001). At 24 months after surgery, GIQLI in bypass plus colostomy group and bypass group was 122.3±5.3 and 92.8±16.6, respectively, with a significant difference (t=9.276, P<0.001). At 12 and 24 months after surgery, NRS in bypass plus colostomy group was significantly better than that in bypass group (both P<0.001). At 24 months after surgery, NRS in bypass plus colostomy group was 0.9±0.7, while that in bypass group was 3.7±2.7. There was a significant difference between two groups (t=5.585, P<0.001). At 6, 12 and 24 months after surgery, the improvement of ABS in bypass plus colostomy group was also significantly better than that in bypass group. At 24 months after surgery, ABS in bypass plus colostomy group was 0.6±0.6, while that in bypass group was 2.5±1.0, with a significant difference between two groups (t=8.797, P<0.001). At 1 year after surgery, barium enema examination was performed in all the patients of both groups. The barium emptying time was (21.2±3.8) hours and (95.8±86.2) hours in bypass plus colostomy group and bypass group respectively. The former group was significantly better than the latter group (t=4.740, P<0.001). Conclusions: Laparoscopic SCBCAC is an effective and safe procedure for the treatment of senile slow transit constipation and can significantly improve prognosis. Its clinical efficacy is better than laparoscopic SCBAC.

Abstract
Objective: To explore the value of cytokines and procalcitonin (PCT) in predicting the potential pathogen and the severity of infection in children with hematological malignancies. Methods: This was a prospective cohort study. A total of 1 543 children (3 912 episodes) with hematological malignancies admitted to the Department of Hematology/Oncology in Children's Hospital of Zhejiang University School of Medicine from November 2010 to June 2018 were prospectively enrolled in this study. According to the pathogen, the patients were divided into sepsis group with positive blood culture (380 patients/608 episodes), sepsis group with negative blood culture (539/1 484), non-septic infection group (549/1 709), viral infection group (18/21) and fungal infection group (57/90). The patients were also divided into two groups in either shock group (171/187) or non-shock group (1 372/3 725). Meanwhile, 89 children (112 episodes) with matched hematological malignancies without fever were enrolled as the control group. The levels of PCT and cytokines were measured for detecting the potential relationship between these markers and infection severity. Mann-Whitney U test or Kruskal-Wallis H test was used to compare the differences between groups. The Receiver Operator Characteristic curve analysis was used to explore the predictive value. Results: (1) There were significantly higher levels of interleukin (IL) 6 (H=210.002, P<0.01), IL-10 (H=223.045, P<0.01), and PCT (H=76.799, P<0.01) in the infection group, with area under curre (AUC) of 0.67 (95%CI 0.64-0.69), 0.69 (95%CI 0.66-0.71) and 0.59 (95%CI 0.56-0.61), respectively. (2) Among the patients in the shock group, IL-6 (Z=11.460, P<0.01), IL-10 (Z=14.242, P<0.01) and PCT (Z=10.813, P<0.01) were significantly higher than those in the non-shock group, with the AUC of 0.75 (95%CI 0.70-0.79), 0.81 (95%CI 0.77-0.84) and 0.73 (95%CI 0.69-0.77), respectively. (3) In patients with septic shock, the incidence of Gram negative bacteria (GNB) infection (60 episodes) was significantly higher than Gram positive bacteria (GPB) infection (22 episodes) (χ(2)=29.665, P<0.01). The AUC of IL-6, IL-10 and PCT for predicting GNB infection were 0.75 (95%CI 0.72-0.78), 0.82 (95%CI 0.79-0.85) and 0.67 (95%CI 0.63-0.70), respectively. (4) The predictive power of IL-6, IL-10 and PCT combination (AUC=0.994) was superior to IL-10 alone (AUC=0.810) in predicting septic shock (Z=10.211, P<0.01). Conclusions: IL-6 and IL-10 are better predictors of GNB infection than PCT in hematology-oncology children. Furthermore, the combination of these two cytokines and PCT is more valuable in predicting the severity of infection.
