Abstract
Objective: To compare the patient-reported outcomes and short-term clinical outcomes between robotic-assisted and laparoscopic-assisted radical gastrectomy for locally advanced gastric cancer. Methods: This single-center prospective randomized controlled trial was conducted in the Department of Gastrointestinal Surgery,Affiliated Hospital of Qingdao University from October 2020 to August 2022. Patients with locally advanced gastric cancer who were to undergo radical gastrectomy were selected and randomly divided into two groups according to 1∶1, and received robotic surgery and laparoscopic surgery, respectively. Patient-reported outcomes and short-term clinical outcomes (including postoperative complications, surgical quality and postoperative short-term recovery) were compared between the two groups by t test, Mann-Whitney U test, repeated ANOVA, generalized estimating equation, χ2 test and Fisher's exact test. Results: A total of 237 patients were enrolled for modified intention-to-treat analysis (120 patients in the robotic group, 117 patients in the laparoscopic group). There were 180 males and 59 females, aged (63.0±10.2) years (range: 30 to 85 years). The incidence of postoperative complications was similar between the robotic group and laparoscopic group (16.7% (20/120) vs. 15.4% (18/117), χ2=0.072, P=0.788). The robotic group had higher patient-reported outcomes scores in general health status, emotional, and social domains compared to the laparoscopic group, differences in time effect, intervention effect, and interaction effect were statistically significant (general health status: χ2 value were 275.68, 3.91, 6.38, P value were <0.01, 0.048, 0.041; emotional: χ2 value were 77.79, 6.04, 6.15, P value were <0.01, 0.014, 0.046; social: χ2 value were 148.00, 7.57, 5.98, P value were <0.01, 0.006, 0.048). However, the financial burden of the robotic group was higher, the differences in time effect, intervention effect and interaction effect were statistically significant (χ2 value were 156.24, 4.08, 36.56, P value were<0.01, 0.043,<0.01). Conclusion: Compared to the laparoscopic group, the robotic group could more effectively relieve postoperative negative emotions and improve recovery of social function in patients.

Abstract
Pulmonary artery sling in adults is a rare congenital vascular malformation usually accompanied by tracheal and bronchial stenosis. Due to its high mortality risk and relatively poor prognosis, it has rarely been reported in adults. We reported a middle-aged patient who presented with shortness of breath, predominantly after activity, since childhood. He was diagnosed with "tracheal stenosis" in another hospital and received symptomatic treatment. The diagnosis of left pulmonary artery sling with congenital tracheal stenosis was confirmed by multi-slice spiral CT (MSCT), airway examination with flexible bronchoscope and 3D image post-processing system. Data from this case and the related literatures have been summarized and analyzed. This will help clinicians to improve their level of diagnosis and treatment.

Abstract
Objective: To explore the key points for preventing and reducing severe pre-eclampsia (SPE) and its severe complications in the tertiary medical referral system of a second-tier city by analyzing the clinical characteristics of SPE. Methods: The clinical data of 341 patients with SPE who terminated pregnancy in Women and Children's Hospital, School of Medicine, Xiamen University, from January 1, 2020 to December 31, 2022 were retrospectively analyzed, and the pre-eclampsia (PE) risk factors, clinical characteristics and severe complications of SPE between the patients referred from primary hospitals (referral group) and the patients received regular prenatal care in the tertiary referral center (central group) were compared, as well as the influence of the referral timing on the maternal and perinatal outcomes. Results: Among the 341 cases of SPE, 92 cases were in the referral group and 249 cases were in the central group. (1) Analysis of PE risk factors: there was no statistical difference in the proportion of risk factors of PE between these two groups [75.0% (69/92) vs 71.9% (179/249); χ2=0.328, P=0.567]. (2) Analysis of clinical features: the gestational ages at the PE early warning factors onset, at the PE first symptom onset and at SPE diagnosed, pregnancy terminated and onset of SPE severe complications in the referral group were significantly earlier than those in the central group (all P<0.05), the proportions of terminating pregnancy before 32 weeks of gestation, between 32 and 34 weeks of gestation, intensive care unit (ICU), neonatal ICU hospitalization and fetal growth restriction in single pregnancies were higher than those in the central group, while the live birth rate was lower than that in the central group (all P<0.05). (3) Analysis of SPE severe complications: the rates of SPE severe complications in the referral group was higher than that in the central group [28.3% (26/92) vs 13.7% (34/249); χ2=9.885, P=0.002]. Among them, the rates of placental abruption [7.6% (7/92) vs 2.8% (7/249); χ2=3.927, P=0.048] and still birth [6.5% (6/92) vs 0.4% (1/249); χ2=9.656, P=0.002] in the referral group were significantly higher than those in the central group. (4) Analysis of referral timings: the timings included referral after onset of SPE severe complications (9.8%, 9/92), referral after SPE diagnosed (63.0%, 58/92), referral after detection of SPE early warning signs (20.7%, 19/92) and referral after detection of PE risk factors (6.5%, 6/92). The gestational ages at SPE diagnosed and pregnancy terminated in group of referral after onset of SPE severe complications and group of referral after SPE diagnosed were significantly earlier than those in group of referral after detection of PE early warning signs and group of referral after detection of PE risk factors (P<0.05). The earlier the referral, the higher the live birth rates (P<0.05). Conclusions: The tertiary referral center of the second-tier city plays an important role in reducing the maternal and perinatal damage of PE. The timing of referral in primary medical institutions is the key point of reducing the occurrence of SPE severe complications and maternal, perinatal damage of PE. It is necessary for medical institutions of all levels in all regions to improve the ability of early identification and early intervention for PE, to enhance the awareness of SPE and its severe complications prevention and control. Primary medical institutions should especially pay attention to raise the consciousness of PE risk factors and early warning signs, and to improve the ability of PE risk factors and early warning signs screening.

Abstract
Interaction exists in lung cancer and microbiota. Lung microecological homeostasis can improve the immune tolerance, enhance immune suppression, and inhibit inflammatory responses, to reduce the lung cancer; while lung cancer can lead to pulmonary microecological imbalance, change the lung environment, and promote tumor cell proliferation. Therefore, modulating microbial flora and microecological immunotherapy may be a potential and preventive treatment for lung cancer, to restore tumor immunosuppression and improve patient survival. However, the individual differences in the lung microecology, because of different genetics, ethnic characteristics, and dietary habits, increasing the difficulty of precise diagnosis and treatment, which is also the current bottleneck in the application of microecological immunotherapy. Otherwise, the effectiveness of regulatory measures such as probiotics, prebiotics or antimicrobials is questionable. The research on microbial flora is still in its infancy, and further exploration is needed to form a standardized, effective, and precise treatment plan. So, standardized, effective, and precise microbial flora treatment strategies need to be further explored.

Abstract
Objective: To summarize the follow-up outcomes of frontal drill out procedures (draf Ⅱb, extended draf Ⅱb and draf Ⅲ) using mucosal flaps, and discuss the surgical indications of different mucosal flaps and their potential benefits to the opening of the frontal neo-ostium. Methods: A total of 48 patients with chronic rhinosinusitis or frontal mucoceles treated by draf Ⅱb, extended draf Ⅱb and draf Ⅲ between 2013 and 2019 in Beijing TongRen Hospital were enrolled in this study. Twenty-four patients who were treated with mucosal flaps were considered as mucosal flap group (including 19 males and 5 females, aging from 19 to 71 years), and the other 24 patients who didn't have neo-ostium reconstruction were considered as control group (including 18 males and 6 females, aging from 21 to 63 years). The frontal neo-ostium crosssectional area was measured with osiriX® 7 days and 1 year postoperatively. Lund-Kennedy score (LKS) was also completed to analyze the difference of therapeutic effect between mucosal flap group and control group. SPSS 23.0 software was used for statistical analysis. Results: The postoperative follow-up time was 18 to 102 months. The postoperative epithelialization time in the mucosal flap group and the control group was (2.5±0.9) months and (3.0±0.7) months (Mean±SD), respectively, with statistically significant (t=1.97, P=0.024). At the end of follow-up, 23 cases (95.8%) had well opened frontal neo-ostium, 1 case (4.2%) was re-stenosed, and there was no revision surgery in the mucosal flap group. In the control group, 16 cases (66.7%) had well opened frontal neo-ostium, 8 cases (33.3%) were re-stenosed, 4 cases (16.7%) had revision surgery. The mucosal flap group had much fewer stenosis cases than control group (χ2=4.92, P=0.027). The neo-ostium area in the mucosal flap group and the control group was reduced by (0.87±0.58) cm2 and (1.54±1.15) cm2 1 year after operation respectively, with statistically significant (t=1.72, P=0.046). There was no case of frontal sinus atresia and no surgical complication in both groups. The two-factor repeated measurement analysis of variance after surgery showed that the average LKS of the mucosal flap group was 0.78 points lower than that of the control group. In other words, the influence of grafting technique on LKS was statistically significant (F=5.33, P=0.035). Conclusions: The application of mucosal flaps to cover the denuded bone during frontal drill out procedures can prohibit mucosal scar and new bone formation, and significantly reduce the stenosis rate of frontal neo-ostium.

Abstract
Objective: The investigation and research on the application status of Hepatic Venous Pressure Gradient (HVPG) is very important to understand the real situation and future development of this technology in China. Methods: This study comprehensively investigated the basic situation of HVPG technology in China, including hospital distribution, hospital level, annual number of cases, catheters used, average cost, indications and existing problems. Results: According to the survey, there were 70 hospitals in China carrying out HVPG technology in 2021, distributed in 28 provinces (autonomous regions and municipalities directly under the central Government). A total of 4 398 cases of HVPG were performed in all the surveyed hospitals in 2021, of which 2 291 cases (52.1%) were tested by HVPG alone. The average cost of HVPG detection was (5 617.2±2 079.4) yuan. 96.3% of the teams completed HVPG detection with balloon method, and most of the teams used thrombectomy balloon catheter (80.3%). Conclusion: Through this investigation, the status of domestic clinical application of HVPG has been clarified, and it has been confirmed that many domestic medical institutions have mastered this technology, but it still needs to continue to promote and popularize HVPG technology in the future.

Abstract
Objective: To analyze the Staphylococcal enterotoxins, Staphylococcal enterotoxin genes, drug resistance and molecular typing of 41 Staphylococcus aureus isolates from 2 food-borne illness outbreaks on 21 August and 27 September 2020 in Guangzhou. Methods: A total of 41 Staphylococcus aureus isolates from 2 outbreaks were analyzed by multilocus sequence typing (MLST) and spa typing. The Staphylococcal enterotoxins typing and the Staphylococcal enterotoxin genes of the isolates were analyzed by ELISA and PCR, respectively. The antimicrobial susceptibility of the isolates was performed by disc diffusion. 21 Staphylococcus aureus isolates were characterized using whole genome sequencing (WGS). Based on the whole genome single nucleotide polymorphism (SNP), the phylogenetic tree was constructed by Snippy. Results: 41 Staphylococcus aureus isolates were divided into 2 types by MLST and spa typing: ST6-t701 and ST7-t091. 2 ST7-t091 isolates were identified as methicillin-resistant Staphylococcus aureus (MRSA). 25 ST7-t091 isolates and 14 ST6-t701 isolates were methicillin-sensitive Staphylococcus aureus (MSSA), and were resistant to 7 and 6 antibiotics, respectively. All isolates were positive for sea by PCR. WGS revealed all 21 isolates carried scn, sak, sea, hla, hld, hlgA, hlgB, hlgC, lukD virulence genes. The results showed the isolates contained an immune evasion cluster type D which located in bacteriophage ϕSa3. The SNP phylogenetic tree showed 2 MRSA ST7-t091 were constituted a separate clade from the 12 MSSA ST7-t091 isolates and 7 ST6-t701 isolates showed high similarity to each other. Conclusion: Base on the results of phylogenetic analysis, the 2 food-borne illness outbreaks occurred on 21 August and 27 September 2020 are caused by the combination of the MRSA ST7-t091 strain and the MSSA ST7-t091 strain, and the MSSA ST6-t701 strain, respectively. All isolates have high level of antibiotic resistance and carry high virulent genes.

Abstract
Objective: To compare the short-term and long-term outcomes between robotic-assisted and laparoscopic-assisted radical right hemicolectomy in patients with adenocarcinoma of the right colon. Methods: Retrospective review of a prospectively collected database identified 288 right colon cancer patients who underwent either robotic-assisted (n=57) or laparoscopic-assisted right hemicolectomy (n=231) between October 2014 and October 2020 at Department of Gastrointestinal Surgery, the Affiliated Hospital of Qingdao University. There were 161 males and 127 females, aging (60.3±12.8) years (range: 17 to 86 years). After propensity score matching as 1∶4 between robotic-assisted and laparoscopic-assisted right hemicolectomy, there were 56 cases in robotic group and 176 cases in laparoscipic group. Perioperative outcomes and overall survival were compared between the two groups using t test, Wilcoxon rank sum test, χ2 test, Fisher exact test, Kaplan-Meier method and Log-rank test, respectively. Results: The total operative time was similar between the robotic and laparoscopic group ((206.9±60.7) minutes vs. (219.9±56.3) minutes, t=-1.477, P=0.141). Intraoperative bleeding was less in the robotic group (50 (20) ml vs. 50 (50) ml, Z=-4.591, P<0.01), while the number of lymph nodes retrieved was significantly higher (36.0±10.0 vs. 29.0±10.1, t=4.491, P<0.01). Patients in robotic group experienced significantly shorter hospital stay, shorter time to first flatus, and defecation (t: -2.888, -2.946, -2.328, all P<0.05). Moreover, the overall peri-operative complication rate was similar between robotic and laparoscopic group (17.9% vs. 22.7%, χ²=0.596,P=0.465). The 3-year overall survival were 92.9% and 87.9% respectively and the 3-year disease-free survival rates were 83.1% and 82.6% with no statistical significance between the robotic and laparoscopic group (P>0.05). Conclusions: Compared to laparoscopic-assisted right hemicolectomy, robot-assisted right hemicolectomy could improve some short-term clinical outcomes. The two procedures are both achieving comparable survival.

Abstract
Objective: To investigate theaccuracy of artificial intelligence sleep staging model in patients with habitual snoring and obstructive sleep apnea hypopnea syndrome (OSAHS) based on single-channel EEG collected from different locations of the head. Methods: The clinical data of 114 adults with habitual snoring and OSAHS who visited to the Sleep Medicine Center of Beijing Tongren Hospital from September 2020 to March of 2021 were analyzed retrospectively, including 93 males and 21 females, aging from 20 to 64 years old. Eighty-five adults with OSAHS and 29 subjects with habitual snoring were included. Sleep staging analysis was performed on the single lead EEG signals of different locations (FP2-M1, C4-M1, F3-M2, ROG-M1, O1-M2) using the deep learning segmentation model trained by previous data. Manual scoring results were used as the gold standard to analyze the consistency rate of results and the influence of different categories of disease. Results: EEG data in 124 747 30-second epochs were taken as the testing dataset. The model accuracy of distinguishing wake/sleep was 92.3%,92.6%,93.5%,89.2% and 83.0% respectively,based on EEG channel Fp2-M1, C4-M1, F3-M2, REOG-M1 or O1-M2. The mode accuracy of distinguishing wake/REM/NREM and wake/REM/N1-2/SWS , was 84.7% and 80.1% respectively based on channel Fp2-M1, which located in forehead skin. The AHI calculated based on total sleep time derived from the model and gold standard were 13.6[4.30,42.5] and 14.2[4.8,42.7], respectively (Z=-2.477, P=0.013), and the kappa coefficient was 0.977. Conclusions: The autonomic sleep staging via a deep neural network model based on forehead single-channel EEG (Fp2-M1) has a good consistency in the identification sleep stage in a population with habitual snoring and OSAHS with different categories. The AHI calculated based on this model has high consistency with manual scoring.

Abstract
Pseudomonas aeruginosa is one of the common multidrug-resistant bacteria in the clinic. Because it can produce a "protective" biofilm, it can affect the penetration and killing efficacy of antibacterial drugs, leading to the formation of a persistent and persistent chronic infection in the host. Biofilms make Pseudomonas aeruginosa resistant to antibacterials and evasive to the host's immune system. Therefore, traditional conventional antibacterials are difficult to achieve effective bactericidal treatment. Understanding the process of P. aeruginosa biofilm formation and the regulatory mechanisms that affect biofilms can provide ideas and methods for our future research on new antibacterial drugs.

Abstract
Objective: To investigate the effect of rosiglitazone (RGZ) on the expression of peroxisome proliferator-activated receptor gamma (PPARγ) and heme oxygenase-1 (HO-1) in hepatic stellate cells (HSCs). Methods: In vitro activated hepatic stellate cell-T6 (HSC-T6) as research subjects were divided into blank control group, RGZ intervention group, and RGZ + ZnPP-IX mutual intervention group. MTT colorimetry method was used to measure the condition of cell proliferation. ELISA was used to detect the content of hyaluronic acid (HA) and type III procollagen peptide (PIIIP) in the cell supernatant. Real-time quantative PCR, western blot and immunocytochemistry were used to detect the relative expression levels of PPARγ, HO-1 mRNA and protein. One-way analysis of variance was used to compare the sample mean between multiple groups, and LSD test was used for comparison between two groups. Results: The proliferation activity of HSC-T6 and the expressions of HA and PIIIP in the RGZ intervention group were significantly lower than those in the blank control group (P < 0.01), but the relative expression levels of PPARγ and HO-1 mRNA and protein were significantly increased compared with the blank control group (PPARγ : 2.97 ± 0.22 vs. 1.07 ± 0.05, 0.96 ± 0.08 vs. 0.31 ± 0.03; HO-1: 4.28 ± 0.73 vs. 1.80 ± 0.36, 1.83 ± 0.26 vs. 0.61 ± 0.09), and the difference was statistically significant (P < 0.01). The proliferation activity of HSC-T6 and the expression of HA and PIIIP was higher in RGZ + ZnPP-IX mutual intervention group as compared with RGZ group (P < 0.05). HO-1 mRNA (3.16 ± 0.38 vs. 4.28 ± 0.73) and protein (1.31 ± 0.17 vs. 1.83 ± 0.26) relative expression levels was decreased, and the difference was statistically significant (P < 0.05). There was no statistically significant difference in the relative expression of PPARγ mRNA and protein (P > 0.05), however, there was a decreasing trend. HO-1 mRNA (1.80 ± 0.36) and protein (0.61 ± 0.09) relative expression was significantly increased in RGZ + ZnPP-IX group as compared to blank control group (P < 0.05). Immunocytochemical staining had consistency with the above results. Conclusion: The effect of rosiglitazone on inducing increased expression of PPARγ, and then inhibiting HSC proliferation activity and collagen production may be realized by regulating its downstream HO-1 expression.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Xiaoaiping injection, a traditional Chinese medical injection extracted from root of Marsdenia tenacissima (Roxb.) Moon, has been exclusively used on curing malignant tumor in China and as adjuvant therapeutic agent for chemotherapeutics, including paclitaxel. AIM OF THE STUDY The goal of this study was to investigate the synergistic inhibitory efficacy of Xiaoaiping injection and paclitaxel on ovarian cancer. The mechanism may be associated with nuclear receptor pregnane X receptor (PXR) regulating its downstream molecules. MATERIALS AND METHODS In vitro, MTT assay, flow cytometry and Hoechst dyeing were used to evaluate the SK-OV-3 cell proliferation, apoptosis and cell cycle respectively. The mRNA and protein expression of PXR and its downstream CYP450 enzymes, transporters and Bcl-2 families were measured by qRT-PCR and Western blot. Rhodamine 123 efflux experiment was conducted to detect the P-gp efflux ability. PXR plasmid and PXR siRNA were transiently transfected into SK-OV-3 cells respectively to establish PXR-overexpressed or PXR-interfered cells. In vivo, xenograft tumor mice model was established by SK-OV-3 cells to estimate the antitumor effect of Xiaoaiping injection combined with paclitaxel. The expressions of PXR and its downstream molecules in tumor tissues were determined to further clarify the potential mechanism. RESULTS Xiaoaiping injection significantly enhanced the anti-proliferation, pro-apoptosis effect of paclitaxel on SK-OV-3 cells. The synergetic effect was displayed by Xiaoaiping injection inhibiting paclitaxel-induced PXR and CAR expression, which subsequently inhibited CYP450 enzymes CYP2C8 and CYP3A4, transporter P-gp and anti-apoptotic proteins Bcl-2 and Bcl-xl in SK-OV-3 cells. In PXR-overexpressed cells, Xiaoaiping injection down-regulated the expression of PXR and its downstream molecules. The result of xenograft tumor model showed that Xiaoaiping injection combined with paclitaxel enhanced anti-tumor effect on ovarian cancer in vivo. CONCLUSIONS Xiaoaiping injection enhances anti-tumor effect of paclitaxel by inhibiting cell proliferation, inducing apoptosis process. The mechanism may be associated with Xiaoaiping injection inhibiting PXR and its downstream metabolic enzymes CYP2C8, CYP3A4, transporter P-gp and anti-apoptosis protein Bcl-2.

Abstract
Heat stress decreases crop growth and yield worldwide. Spermidine (Spd) is a small aliphatic amine and acts as a ubiquitous regulator for plant growth, development and stress tolerance. Objectives of this study were to determine effects of exogenous Spd on changes in endogenous polyamine (PA) and γ-aminobutyric acid (GABA) metabolism, oxidative damage, senescence and heat shock protein (HSP) expression in white clover subjected to heat stress. Physiological and molecular methods, including colorimetric assay, high performance liquid chromatography and qRT-PCR, were applied. Results showed that exogenous Spd significantly alleviated heat-induced stress damage. Application of Spd not only increased endogenous putrescine, Spd, spermine and total PA accumulation, but also accelerated PA oxidation and improved glutamic acid decarboxylase activity, leading to GABA accumulation in leaves under heat stress. The Spd-pretreated white clover maintained a significantly higher chlorophyll (Chl) content than untreated plants under heat stress, which could be related to the roles of Spd in up-regulating genes encoding Chl synthesis (PBGD and Mg-CHT) and maintaining reduced Chl degradation (PaO and CHLASE) during heat stress. In addition, Spd up-regulated HSP70, HSP70B and HSP70-5 expression, which might function in stabilizing denatured proteins and helping proteins to folding correctly in white clover under high temperature stress. In summary, exogenous Spd treatment improves the heat tolerance of white clover by altering endogenous PA and GABA content and metabolism, enhancing the antioxidant system and HSP expression and slowing leaf senescence related to an increase in Chl biosynthesis and a decrease in Chl degradation during heat stress.

Abstract
Objective: To investigate the expression and significance of Nek2B and β-catenin expression in triple negative breast cancer (TNBC) at molecule levels. Methods: By using the methods of bioinformatics [GEO2R online tool, gene ontology (GO) function analysis, KEGG biological pathway enrichment analysis], the differentially expressed genes were screened from TNBC microarray data.Expression levels of Nek2B and β-catenin TNBC cell lines were detected by Western blot and qRT-PCR.From January 1, 2007 to December 31, 2012, eighty cases of TNBC were collected from the Second Hospital of Shanxi Medical University. The expression of Nek2B in TNBC tumor tissue was detected by immunohistochemistry and tissue microarray, and the relationship between Nek2B and clinical pathological characteristics of TNBC was analyzed. Results: Through bioinformatics analysis of the cDNA chip sets of 2 TNBC tumors(GSE38959,GSE27447), 998 differentially expressed genes were obtained in the initial screening, and 13 differentially expressed genes were revealed after intersection. The results of biological pathway analysis showed that the common differential expression genes were closely related to Wnt/β-catenin pathway, among which Nek2 expression showed the greatest difference and was associated with poor prognosis. Expression intensity of Nek2B and repeated β-catenin in the same TNBC cell line was consistent.The results of immunohistochemistry showed that the high expression of Nek2B was related to the high histological stage (G3;84.3% vs.37.9%, P<0.001), lymph node metastasis group (76.7% vs.54.1%, P=0.032), high Ki-67 positive index group (78.6% vs.52.6%, P=0.007) and β-catenin positive expression group (72.5% vs.27.3%, P=0.018). Conclusions: The high level of Nek2B expression is related to a poor prognosis in TNBC patients. In TNBC tissues and cells, the expression of Nek2B is correlated with β-catenin, suggesting that Nek2B may affect the occurrence and development of TNBC by regulating the Wnt/β-catenin patients signaling pathway.

Abstract
Objective: To explore the improvement rate of liver fibrosis in patients with chronic hepatitis B virus infection who received entecavir alone or in combination with anluohuaxianwan for 78 weeks. Methods: Patients with chronic HBV infection were randomly treated with entecavir alone or in combination with anluohuaxian for 78 weeks. Ishak fibrosis score was used for blind interpretation of liver biopsy specimens. The improvement in liver fibrosis condition before and after the treatment was compared. Student's t test and non-parametric test (Mann-Whitney U-Test and Kruskal-Wallis test) were used to analyze the measurement data. The categorical variables were analyzed by Chi-square test method and Spearman's rank correlation coefficient was used to test bivariate associations. Results: Liver fibrosis improvement rate after 78 weeks of treatment was 36.53% (80/219) and the progression rate was 23.29% (51/219). The improvement of liver fibrosis was associated to the degree of baseline fibrosis and treatment methods (P < 0.05). The improvement rate of hepatic fibrosis in patients treated with anluohuaxianwan combined with entecavir at baseline F < 3 (54.74%, 52/95) was significantly higher than that in patients treated only with entecavir (33.33%, 16/48), P = 0.016 and the progression rate of hepatic fibrosis (13.68%, 13/95) was lower than that in patients treated alone (18.75%, 9/48), P = 0.466. In patients with baseline F < 3, the proportion of patients with improved and stable liver fibrosis in the combined treatment group (68.1%, 32/47) was higher than that in the treatment group alone (51.7%, 15/29). Conclusion: Combined anluohuaxianwan and entecavir treatment can significantly improve the improvement rate of liver fibrosis in patients with chronic hepatitis B virus infection. Furthermore, it has the tendency to improve the stability rate and reduce the rate of progression of liver fibrosis.

Abstract
We present a detailed study of the photoinduced magnetization precession and magnetic relaxation in epitaxial Pd/Fe films on MgO(0 0 1) substrates via all-optical pump-probe techniques. We explicitly formulate the correlation between the Gilbert damping and the effective damping in the optical approach. Furthermore, a non-local Gilbert damping induced by spin pumping is demonstrated self-consistently by the Gilbert damping dependence on Pd thickness and the [Formula: see text] relationship of damping with Fe thickness [Formula: see text]. The non-local Gilbert damping enables the determination of spin diffusion length [Formula: see text] in Pd and interfacial spin mixing conductance [Formula: see text]. Our work paves the way toward the optical determination of spin transport parameters.

Abstract
Improving the insulating nature of sulfur and retaining the soluble polysulfides in sulfur cathodes are crucial for realizing the practical application of lithium-sulfur batteries (LSBs). Biomass-based carbon is becoming increasingly popular for fabricating economical and efficient cathodes for LSBs owing to its unique structure. Herein, we report a facile strategy to transform bovine bone with an organic-inorganic structure into cellular hierarchical porous carbon via carbonization and KOH activation, followed by CoS2 modification through hydrothermal treatment. The synthesized composite can load abundant sulfur and produce a dual effect of "physical confinement and chemical entrapment" on polysulfides. The conductive carbon frame with the developed porous structure provides adequate space to accommodate sulfur and physically suppress the shuttle effect of polysulfides. The embedded half-metallic CoS2 sites can chemically anchor the polysulfides and enhance the electrochemical reaction activity as well. Owing to the multifunctional structure and dual restraint effect, the designed electrode exhibits enhanced electrochemical properties including high initial capacity (1230.9 mAh g-1 at 0.2 C), improved cycling stability and enhanced rate capability.

Abstract
Objective: To investigate differentially expressed genes associated with liver cancer using bioinformatics methods, and to screen out molecular markers for early diagnosis of liver cancer and potential molecular targets for immunotherapy. Methods: The microarray data associated with liver cancer were downloaded from Gene Expression Omnibus. JMP software was used for correlation analysis of GSE datasets, Limma program in R language was used to screen out differentially expressed genes, and the Gene Ontology (GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genome (KEGG) pathway analysis were performed for differentially expressed genes. A protein-protein interaction (PPI) network was also established for analysis. An analysis of specific expression associated with liver cancer was performed with reference to RNA-seq transcriptome data for other tumors obtained from TCGA to further identify specific differentially expressed genes in liver cancer, and a survival curve analysis was performed for patients with liver cancer. Results: A total of 92 differentially expressed genes were identified, with 21 upregulated genes and 71 downregulated genes. Through the GO, KEGG, and PPI analyses, RNA-seq data verified that only glypican 3 (GPC3) was upregulated in liver cancer, and MBL2, SDS, SLCO1B3, TDO2, SAA4, and SPP2 were downregulated. Conclusions: GPC3 might act as a target for immunotherapy, and other molecular markers may become molecular markers for early detection of liver cancer and potential targets for immunotherapy.

Abstract
Objective: To observe the therapeutic effects and related mechanism of hemin on the progression of hepatic fibrosis in rats. Methods: Sixty male Wistar rats were randomly divided into normal control group, 4-week model group, 6-week model group, hemin inhibitor zinc protoporphyrin-IX (ZnPP-IX) intervention group and hemin intervention group. Hemin intervention group in complex liver fibrosis model was intraperitonealy administered ZnPP-IX or hemin every other day for 2 weeks from the fourth week. The mRNA expression of HO-1, α-smooth muscle actin (α-SMA) and nuclear factor-κB (NF-κB) in the liver tissue was detected by real-time polymerase chain reaction. Immunohistochemistry was used to detect HO-1 and localization of α-SMA expression. Serum hyaluronic acid, propeptide of type III collagen and hepatic transforming growth factor beta (TGFβ), and interleukin 6 (IL-6) expressions were detected by enzyme-linked immunosorbent assay. The content of hydroxyproline in hepatic tissues was measured by alkaline hydrolysis method. One-way ANOVA was used to compare the mean of each group. The difference between the two groups was compared by independent samples t- test. P-values < 0.05 was considered statistically significant. Results: Compared with model groups and ZnPP-IX intervention group, Hemin's intervention significantly increased the expression of HO-1 mRNA (P < 0.01) and protein distribution in liver tissues, while the expression of alpha-SMA mRNA was significantly decreased (P < 0.05) in portal space and areas around the fibrotic septum, and hepatic sinus. Hyp content and serum hyaluronic acid and propeptide of type III collagen decreased significantly (P < 0.05). Meanwhile, NF-κB p65 mRNA expression and the downstream production of TGFβ and IL-6 in Hemin intervention group were also inhibited (P < 0.05). Conclusion: Hemin can significantly inhibit the progression of hepatic fibrosis in rats by up-regulating HO-1 expression, and the inhibiting activity of NF-κB p65 leads to downstream of the inflammatory factors.

Abstract
Emerging evidences indicate that dysregulated long noncoding RNAs (lncRNAs) are implicated in cancer tumorigenesis and progression and might be used as diagnosis and prognosis biomarker, or potential therapeutic targets. LncRNA H19 has been reported to be upregulated in diverse human cancers; however, its clinical significance in gastric cancer (GC) remains elusive. Expression levels of H19 in 128 pairs of GC and adjacent normal tissues, GC cell lines and GC juices compared to their corresponding controls were detected by real-time quantitative polymerase chain reaction (qPCR) assay. A receiver operating characteristic (ROC) curve and Kaplan-Meier analysis were constructed to evaluate the diagnostic and prognostic values. Univariate and multivariate analysis were performed using the Cox proportional hazard analysis. H19 expression was remarkably increased in GC tissues and cell lines compared with that in the normal control, and its up-regulation was significantly correlated to invasion depth (P < 0.001), advanced TNM stage (P = 0.002) and regional lymph nodes metastasis (P < 0.001) in GC. H19 levels were robust in differentiating GC tissues from controls [area under the curve (AUC) = 0.697; 95% confidence interval (CI) = 0.636-0.752, p<0.01]. Kaplan-Meier analysis demonstrated that increased H19 expression contributed to poor overall survival (P = 0.017) and disease-free survival (P = 0.024) of patients. A multivariate survival analysis also indicated that H19 could be an independent prognostic marker. The levels of H19 in gastric juice from gastric patients were significantly higher than those from normal subjects (P = 0.034). Furthermore, knockdown of H19 expression by siRNA could inhibit cell migration and invasion in GC cells partly via regulating E-cadherin protein expression. H19 might serve as a promising biomarker for early detection and prognosis prediction of GC.

Abstract
Danhong injection (DHI) is made from Salvia miltiorrhiza Bunge. and Carthamus tinctorius L. extract and is widely used in the clinical treatment of cardiovascular and cerebrovascular diseases. This study aimed to evaluate the effect of DHI on cytochrome P450 (CYP450) enzymes in vitro to predict drug-drug interactions based on CYP450 as combination therapy. To assess the inhibitory effect of DHI on CYP450, we detected the IC50 value of DHI on CYP450 in vitro by liquid chromatography/tandem mass spectrometry (LC-MS/MS). Simultaneously, the induction effect of DHI on CYP450s was also evaluated. The relative induction ratios of DHI on CYP1A2, CYP2B6 and CYP3A4 activity were calculated by LC-MS/MS. The expression level of CYP3A4 mRNA was determined by reverse transcription PCR (RT-PCR). The LC-MS/MS data showed DHI intensively inhibit CYP2A6 activity and the intensity of inhibition was followed by CYP2C8, CYP3A4, CYP2C19, CYP2B6, CYP2D6, CYP1A2, CYP2E1 and CYP2C9 in vitro. The results of RT-PCR showed that there is a certain induction of DHI on CYP3A4 mRNA in human primary hepatocytes in vitro. The study suggested that drug-drug interactions might occur in clinical co-administration of drugs owing to the CYP2A6 inhibition and CYP3A4 induction.

Abstract
Background Hypoventilation is the main reason for hypoxia during upper gastrointestinal endoscopy procedures with sedation. The key to preventing hypoxia is to maintain normal ventilation during the procedure. We introduced supraglottic jet oxygenation and ventilation (SJOV) through a new Wei nasal jet tube (WNJ) to reduce the incidence of hypoxia in patients sedated with propofol during upper gastrointestinal endoscopy procedures. Methods In a multicentre, prospective randomized single-blinded study, 1781 outpatients undergoing routine upper gastrointestinal endoscopy who were sedated with propofol by an anaesthetist were randomized into the following three groups: the supplementary oxygen via nasal cannula group [nasal cannula oxygen: O 2 (2 litres min -1 ) was administered via a nasal cannula]; the supplementary oxygen via WNJ group [WNJ oxygen: O 2 (2 litres min -1 ) was administered through a WNJ]; and the SJOV via WNJ group (WNJ SJOV: SJOV was administered via WNJ) at three centres from March 2015 to July 2016. The primary outcome of interest was the incidence of hypoxia (peripheral oxygen saturation of 75-89%). Other adverse events were also recorded. Results Supraglottic jet oxygenation and ventilation decreased the incidence of hypoxia from 9 to 3% ( P <0.0001). No severe hypoxia occurred in the WNJ SJOV group, one instance occurred in the WNJ oxygen group, and two instances were observed in the nasal cannula oxygen supply control group. Supraglottic jet oxygenation and ventilation-related minor adverse events increased significantly within 1 min after the procedure but decreased 30 min later. Conclusions The use of SJOV during upper gastrointestinal endoscopy for patients who are sedated with propofol reduces the incidence of hypoxia, with minor and tolerable adverse events. Supraglottic jet oxygenation and ventilation has a favourable risk-to-benefit ratio and may improve patient safety. Clinical trial registration NCT02436018.

Abstract
Objective: To investigate the prevalence of iron deficiency (ID) and iron deficiency anemia (IDA) in pregnant women in urban areas of China. Methods: The study was a national cross-sectional survey conducted from September 19th, 2016 to November 20th, 2016. According to the classification of the National Bureau of Statistics, all survey sites were set up in 6 regions of the country.Pregnant women were continuously selected using multistage stratified sampling. A total of 12 403 pregnant women were collected and examined for serum ferritin and hemoglobin levels. Results: The median serum ferritin level during pregnancy was 20.60 μg/L (11.78-36.98 μg/L) , the hemoglobin level was (118±12) g/L. With the progress of pregnancy, the levels of serum ferritin and hemoglobin decreased gradually. The median serum ferritin levels in the first, second trimester and third trimester were 54.30 μg/L (34.48-94.01 μg/L) , 28.60 μg/L (16.40-50.52 μg/L) , and 16.70 μg/L (10.20-27.00 μg/L) respectively (P<0.01) . The mean hemoglobin levels were (127±10) g/L, (119±11) g/L and (117±11) g/L respectively (P<0.01) . The prevalence of ID in urban pregnant women was 48.16% (5 973/12 403) , and IDA prevalence was 13.87% (1 720/12 403) . The prevalence of IDA in the first, second trimester and third trimester were 1.96% (20/1 019) , 8.40% (293/3 487) and 17.82% (1 407/7 897) ,respectively (P<0.01) . The prevalence of standardized ID and IDA were significantly different in various regions of China (P<0.01) . The standardized prevalence of ID were relatively higher in East China and Northeast China, 57.37% and 53.41% respectively, while it was the lowest in Southwest China, 30.51%. The standardized prevalence of IDA in South Central, Northwest, and East China were relatively high, 21.30%, 16.97% and 17.53% respectively, and the standardized prevalence of IDA in Southwest China was the lowest, 5.44%, the differents in various regions were significant (all P<0.01) . Conclusion: The current phenomenon of ID and IDA in pregnant women is still very common, and nutrition and health care during pregnancy should be strengthened.

Abstract
Objective:To compare GOSS and a newly proposed modified scoring system for assessment of CRS with osteitis.Method:Seventy-one CRS patients were enrolled prospectively.Their preoperative computed tomography (CT) were assessed for severity and extent of osteitis by two otolaryngologists using OsiriX DICOM Viewer software. The method of measurement was similar with GOSS, which retained scoring maxillary and sphenoid, producing a modified global osteitis score(rang: 0-20). Collected the history and completed VAS, SNOT-22, Lund-Kennedy, Lund-Mackay in preoperative. Postoperative follow-up mounted up to 12 months and evaluating CRS patients' outcome. Compared for test-retest and inter-rater reliability between the modified system and GOSS.Result:There is a significant linear positive correlation between Modified GOSS score and GOSS(r=0.913,P<0.001).And Modified GOSS had more association with pre and postoperative L-M and L-K scores than GOSS (r=0.316, 0.357). The modified GOSS showed the highest inter-rater and test-retest, interclass correlation coefficient (pre-ICC=0.947; post-ICC=0.943).Conclusion:Modified GOSS may be a more suitable and convenient scoring system for clinical practice to grading osteitis.

Abstract
Objective:To study the surgical outcomes of functional endoscopic sinus surgery and radical sinus surgery for refractory rhinosinusitis.Method:A retrospective analysis of 56 cases with refractory rhinosinusitis was performed, who were enrolled in Beijing Tongren hospital from January 2011 to April 2013. According to different surgical methods, all patients were classified into functional endoscopic surgery group (FESS group) and radical sinus surgery group (RSS group). All patients were followed up for more than one year after surgery. Symptom visual analog scale (VAS), peripheral blood eosinophil percentage, serum total IgE, skin prick test (SPT), olfactory function, Lund-Kennedy score and Lund-Mackay score were all examined and analyzed in two groups before and after surgery. SPSS 17.0 was used to do data statistic analysis.Result:There was no significant difference between two groups in age, gender, complicated with allergic rhinitis and asthma (P> 0.05). However, there was significant difference between two groups in the number of patients with previous surgery (P< 0.05). Pre-operative VAS symptom score, Lund-Kennedy score and Lund-Mackay score were higher in RSS group than in FESS group. All patients were followed up for at least one year. VAS symptom score, Lund-Kennedy score and Lund-Mackay score in two groups were compared before and after surgery respectively. VAS symptom score (P< 0.01; P< 0.01), Lund-Kennedy score (P< 0.01; P< 0.01), Lund-Mackay score (P< 0.01; P< 0.01) were significantly lower after surgery. There was no significant difference in VAS symptom scores between two groups postoperatively (P> 0.05). However, Lund-Kennedy score (P< 0.01) and Lund-Mackay score (P< 0.01) were lower in RSS group postoperatively. Among patients with surgery history, Lund-Kennedy score (P< 0.01) and Lund-Mackay score (P< 0.01) were also lower in RSS group at one year follow-up. Conclusion:Radical sinus surgery was more effective in relieving symptoms and reducing inflammation of sinus, compared with functional sinus surgery, especially in refractory sinusitis patients with previous surgery.

Abstract
The aim of this study was to compare the safety and the efficacy of two methods of continuous blood purification (CBP), continuous veno-venous hemofiltration (CVVH) and high volume hemofiltration (HVHF), for treatment of infantile sepsis. Eighty-six children with sepsis were enrolled in this study and randomly divided into two groups with 47 cases in the CVVH group and 39 cases in the HVHF group. Survival rate, duration of blood filtration, mean arterial pressure (MAP), mean heart rate and SaO2, APACHE II score, procalcitonin, hs-CRP and TXB2 were compared between the two groups. Results showed that survival rate, MAP, mean heart rate and SaO2 in the two groups did not have any significant differences. Duration of blood filtration and APACHE II score in the HVHF group was significantly shorter than that in the CVVH group. After therapy, levels of procalcitonin, hs-CRP and TXB2 declined dramatically in both groups, however this reduction was more significant in the HVHF group. We conclude that HVHF is a safer and more effective method as it produced stable hemodynamics, shorter filtration time, better APACHE II scores and better results in alleviating inflammatory reactions.

Abstract
Objective: To investigate the imaging diagnosis, treatment and prognosis of primary hepatic neuroendocrine tumors. Methods: The clinical features, imaging manifestations, histopathological and immunohistochemical findings and interventional therapy of 6 patients identified with pathologically confirmed primary hepatic neuroendocrine tumors were retrospectively analyzed, and the related literatures were reviewed. Results: All 6 patients presented with symptoms of abdominal pain. 4 patients had solitary hepatic mass and 2 patients had multiple hepatic masses. Magnetic resonance imaging showed low signal intensity on T1 weighted imaging, high signal intensity on T2 weighted imaging and clear boundary; the arterial phase of enhancement scan was uneven and enhanced, and portal venous phase or delayed phase showed continuous enhancement, surrounded by ring enhanced capsule. A pathological diagnosis was primary neuroendocrine tumor of the liver. After interventional treatment, 6 patients had some therapeutic effects. Among them, 4 patients underwent multiple interventional therapies, followed by 4 years of follow-up has shown satisfactory results. Conclusion: Primary hepatic neuroendocrine tumors are very rare and their imaging manifestations are specific. Eventually, relies on pathological and immunohistochemical diagnosis. Transarterial chemoembolization therapy can bring satisfactory results in the treatment of primary hepatic neuroendocrine tumor.

Abstract
Objective: To investigate the relationship between the status of epidermal growth factor receptor (EGFR) mutations and brain metastases in patients with lung adenocarcinoma. Methods: From August 2010 to May 2015, a total of 1 063 lung adenocarcinoma patients with identified status of EGFR mutations in Shanxi Cancer Hospital were enrolled, of which 456 patients had EGFR mutations. Multivariate Logistic regression model was used to analyze the correlation between EGFR mutation status and brain metastases in patients with lung adenocarcinoma. Results: In 125 patients with brain metastases before initial treatment, 65 patients had EGFR mutations, including 36 patients with deletion mutations in exon 19. The frequency of EGFR 19 exon mutation was 28.8% (36/125). Among 456 patients with EGFR mutations, 65(14.3%) patients were with brain metastases, in which 36(55.0%) had deletion mutations in exon 19. The multivariate analysis showed that age, Eastern Cooperative Oncology Group (ECOG) score, EGFR mutations and N staging were associated with brain metastases(P<0.05). Further subgroup multivariate analyses showed that age, ECOG score, mutation status in exon 19 and N staging were associated with brain metastases (P<0.05). Conclusions: EGFR mutation status is related to brain metastases. Mutations in EGFR exon 19 is an independent risk factor for brain metastases.

Abstract
BACKGROUND Selenium is a crucial mineral with antioxidant and immune functions, and selenium deficiency may increase the risk of coronary heart disease (CHD). However, the effect of selenium supplementation on CHD is still controversial according to numerous randomized controlled trials (RCTs). The aim of our meta-analysis study was to investigate the impact of selenium on CHD. METHODS PUBMED, EMBASE, MEDLINE, and the Cochrane Central Register of Controlled Trials databases were systematically searched to identify RCTs evaluating the effect of selenium supplementation on CHD mortality, blood lipid profile (high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and total cholesterol), serum C-reactive protein (CRP), and the level of glutathione peroxidase (GSH-PX) from inception until September 20, 2016. Odds ratio of CHD mortality and the associated 95% confidence intervals (CIs) were calculated using the fixed effect model. Weighted mean difference or standardized mean difference (SMD) and 95% confidence intervals (CIs) were calculated to determine the lipid profile, serum CRP, and GSH-PX using fixed effect or random effect models depending on the observed heterogeneity. RESULTS A total of 16 eligible RCTs with 43998 participants were included. Significant effects were observed for serum CRP (SMD=-0.48; 95% CI, -0.96 to 0; p=0.049) and GSH-PX (SMD=0.5; 95% CI, 0.36-0.64; p<0.001) after selenium supplementation. However, selenium supplementation was not statistically associated with CHD mortality and an aberrant lipid profile. CONCLUSION Selenium supplementation decreased serum CRP and increased the GSH-PX level, suggesting a positive effect on reducing oxidative stress and inflammation in CHD. However, selenium supplementation is not sufficient to reduce mortality and to improve the lipid status.

Abstract
This study investigates the effects of restricted grazing time on forage selectivity and meat fatty acid deposition of lambs compared to a traditional grazing system. Results showed that the animals preferred to graze pasture species that were more palatable and lower in fibre, while demonstrating a partial preference for species with high protein levels. Leymus chinensis was more preferentially selected by lambs grazing pasture for shorter periods than longer periods. Lambs that grazed for 4 h per day had a high LNA (α-linolenic acid) intake. The accumulation of LNA and its elongation products in tissue was closely related to the LNA level in diet. Therefore, allowing lambs to graze for at least 4 h per day resulted in a meat fatty acid profile that is richer in health-promoting fatty acids. In particular, the highest DHA (docosahexaenoic acid) was observed in meat from lambs which grazed pasture for 4-h versus 8- and 12-h. It can be concluded that, in grassland systems, a healthier meat fatty acid profile for humans and the potential for better pasture management is achieved by limiting the grazing of lambs to 4 h per day rather than grazing over longer time periods.

Abstract
Intraoperative cell salvage (IOCS) has been widely used to reduce allogeneic blood transfusion and prevent blood transfusion related complications during surgery. However, due to the risk of transfusion related reaction, contamination, and immunological reaction, its use for tumor patients has been controversial and limited. To explore the feasibility of the application of IOCS in cancer patients, we reported 2 cases of renal cell carcinoma (RCC) with tumor embolism in IVC that underwent radical nephrectomy,and inferior caval venous thrombectomy receiving IOCS combined with leukocyte depletion filter (LDF) from August 2016 to November 2016 in our hospital. The cell saver blood salvage (Haemonetics, 5+) was used for these 2 cases. The salvaged blood was filtered through the LDF before infusion. For case 1 (male 45-year-old) the total operation time was 505 min, and the estimated blood loss was 4 500 ml. A total of 1 000 mL autologous blood, 12 u allogeneic packed red blood cells (PRBC), 1 200 mL fresh frozen plasma (FFP) were infused during the procedure. The patient was discharged from hospital after 75 days without complications. The postoperative follow-up for 3 months showed no tumor recurrence or metastasis. For case 2 (a male patient, aged 51 years), the total operation time was 490 min, and the estimated (blood loss was 7 000 mL. the patient received 2 700 mL autologous blood transfusion, 12 u allogeneic packed red blood cells (PRBC), and 2 400 mL fresh frozen plasma (FFP). The patient was discharged from hospital after 86 days without severe complications. the postoperative follow-up for 6 months showed no tumor recurrence or metastasis for this patient. Other relevant retrospective studies with this technique showed that cell salvage could be used safely in many kinds of cancer patients, for example, bladder cancer, liver cancer and kidney cancer. Furthermore,numerous researches have proved the safety and efficacy of the combination of these two techniques, the intraoperative cell salvage technique and leucocyte depletion filter in cancer patients. Here we only reported two cases using IOCS and LDF. Further work is needed to determine whether the use of intraoperative cell salvage combined with leukocyte depletion filter can be used safely for patients with HCC.

Abstract
Virus-specific T cells can recognize allogeneic HLA (allo-HLA) through TCR cross-reactivity. The allospecificity often differs by individual (private cross-reactivity) but also can be shared by multiple individuals (public cross-reactivity); however, only a few examples of the latter have been described. Because these could facilitate alloreactivity prediction in transplantation, we aimed to identify novel public cross-reactivities of human virus-specific CD8+ T cells directed against allo-HLA by assessing their reactivity in mixed-lymphocyte reactions. Further characterization was done by studying TCR usage with primer-based DNA sequencing, cytokine production with ELISAs, and cytotoxicity with 51 chromium-release assays. We identified three novel public allo-HLA cross-reactivities of human virus-specific CD8+ T cells. CMV B35/IPS CD8+ T cells cross-reacted with HLA-B51 and/or HLA-B58/B57 (23% of tetramer-positive individuals), FLU A2/GIL (influenza IMP[58-66] HLA-A*02:01/GILGFVFTL) CD8+ T cells with HLA-B38 (90% of tetramer-positive individuals), and VZV A2/ALW (varicella zoster virus IE62[593-601] HLA-A*02:01/ALWALPHAA) CD8+ T cells with HLA-B55 (two unrelated individuals). Cross-reactivity was tested against different cell types including endothelial and epithelial cells. All cross-reactive T cells expressed a memory phenotype, emphasizing the importance for transplantation. We conclude that public allo-HLA cross-reactivity of virus-specific memory T cells is not uncommon and may create novel opportunities for alloreactivity prediction and risk estimation in transplantation.

Abstract
Growth traits are important economic traits in broiler chicken production. AluI and Hin1I loci are two restriction sites, which are respectively located in exons 2 and 3 of the IGF-1R gene. These two loci are significantly related to the growth traits in Jinghai Yellow chickens. In this study, a correlation analysis was performed between these two loci and the growth traits of Bian chickens. The results showed a G376A mutation at the AluI site and a C919A mutation at the Hin1I site, which respectively resulted in three genotypes AA, AB, and BB in exon 2 and three genotypes CC, CD, and DD in exon 3. Correlation analysis showed that the female Bian chickens with the AA genotype of the AluI locus had higher body weights than those with the AB genotype (P < 0.05) at 8, 14, 16, and 18 weeks; individuals with CD genotype of Hin1I locus had higher body weights at 6, 8, 10, 12, and 14 weeks compared to the CC genotype (P < 0.05 or P < 0.01). Combined genotypes analysis showed that at the age of 8, 14, 16, and 18 weeks, the body weight of AACC genotype combination was higher than that of the ABCC genotype combination (P < 0.05); at the age of 6, 8, 12, 14, 16, and 18 weeks, the AACD genotype combination had higher (P < 0.05 or P < 0.01) body weight than that of the ABCC genotype.

Abstract
The measurement of internal magnetic fluctuation is important for the study of transport in tokamak plasmas. The runaway electron transport induced by the sawtooth crash can be used to obtain the internal magnetic fluctuation. Inversed sawtooth-like activities on hard x-ray (HXR) fluxes following sawtooth activities were observed after the application of electrode biasing on J-TEXT tokamak. The runaway diffusion coefficient Dr is deduced to be about 30 m2/s according to the time delay of HXR flux peaks to the sawtooth crashes. The averaged value of normalized magnetic fluctuation in the discharges with electrode biasing was increased to the order of 1 × 10-4.

Abstract
OBJECTIVE This study was performed to evaluate the regulating effects of acetylpuerarin on inflammation in an Alzheimer's disease (AD) rat model and an inflammatory cell model. METHODS Healthy female Wistar rats and mouse BV2 microglia cells were selected. AD rat models were established with the method of bilateral intrahippocampal amyloid-β(Aβ)1-42 injections and the inflammatory cell models were established using Aβ25-35-induced mouse BV2 microglia cells. The cytotoxicity of acetylpuerarin on BV2 microglial cells was detected by MTT assay and the morphological changes of BV2 microglia cells were observed under inverted phase contrast microscope. As inflammatory parameters, the expressions of IL-1β, iNOS, IL-6 and TNF-α were examined by Elisa, Immunohistochemistry, Quantitative real-time PCR (qRT-PCR), Western blot and Immunofluorescence analyses. We also examined the acetylpuerarin's effect on the activity of PKC-δ, IKKβ and caspase-8/caspase-3 pathway. RESULTS Acetylpuerarin exerted no significant cytotoxicity on BV2 microglia cells and was applied in all subsequent experiments. Acetylpuerarin treatment mitigated Aβ25-35-induced morphological changes associated with microglia activation. Moreover, the expressions of caspase-8, cleaved caspase-3, PKC-δ, IKKβ, iNOS, IL-1β and TNF-α in Aβ25-35-stimulated BV2 microglia cells were significantly suppressed by acetylpuerarin and in a dose-dependent manner. Additionally, the expression of IL-1β in hippocampus and the level of IL-6 in serum of Aβ1-42 treated rat were reduced by acetylpuerarin and in a concentration-dependent manner. CONCLUSION Our results suggest that acetylpuerarin's anti-inflammation mechanism on AD may be mediated through the PKC-δ-dependent caspase signalling pathway.

Abstract
Objective: To compare the clinical efficacy of the direct anterior approach (DAA) and the posterolateral approach (PLA) for total hip arthroplasty (THA) in the lateral decubitus position. Methods: From July to December, 2014, 104 patients randomly divided into two equal groups of the DAA group and the PLA group underwent unilateral primary THA procedures.All procedures were performed by the same surgeon in the Department of Orthopaedics, the Affiliated Anhui Provincial Hospital of Anhui Medical University.General data, perioperative index, postoperative function and radiological evaluation were recorded and statistically analyzed. Results: The patients had an average follow-up of 14 (range, 10-16) months.No significant differences were detected with respect to the operation time, incision length, preoperative Hb concentration and transfusion rate between two groups (P> 0.05 for all comparisons). However, there were significant differences associated with the intraoperative bleeding, postoperative drainage and postoperative Hb concentration in the two groups(P<0.05 for all comparisons). The DAA group showed significant superior outcomes compared with the PLA group in the Harris hip scores [(83.6±7.1) vs (79.8±6.6), P<0.05], WOMAC[ (28.9±6.1) vs (36.1±6.9), P<0.001], and VAS pain scores[ (2.2±0.9) vs (2.9±1.1), P<0.05]at 1 month after surgery. No differences were seen between the study groups in the evaluation of radiography and the incidence of adverse event (P> 0.05 for all comparisons). Conclusions: Compared with the posterolateral approach, the present study shows the exciting results in patients underwent the DAA THA in the lateral decubitus position at early follow-up.The advantages of THA using the DAA include less operative trauma, alleviation of postoperative pain, and faster postoperative rehabilitation. It is a safe, reliable and effective surgery approach.

Abstract
In order to understand the effect of grain moisture of inbred lines at the silking and physiological maturity stages on kernel dehydration rate, 59 maize inbred lines from six subgroups were selected. Grain moisture was measured and QTLs associated with kernel dehydration were mapped. A rapid dehydration evaluation and association analysis revealed eight inbred lines with faster dehydration rate, including Yuanwu 02, K36, Zhonger/O2, Lo1125, Han 49, Qi 319, Hua 160, and PH4CV. A single sequence repeat analysis using 85 pairs detected five QTLs with phenotypic variation contribution ≥10% in the permanent F2 generation populations Zheng 58 x S1776 and Chang 7-2 x K1131, which had LOD threshold values ≥ 3 in both 2013 and 2014. The chromosome region of qFkdr7b had not previously been reported and is preliminarily identified as a new major QTL. A false positive field verification of grain dehydration rate of 53 inbred lines indicated that the screening result of the rapid dehydration inbred lines by specific amplification with marker Phi114 was most similar to the field assessment result, followed by markers Phi127 and Phi029. The rapid dehydration lines selected based on primer Phi114 amplification were also similar to the field dehydration rate and can thus be used for molecular marker-assisted selection. A significant effort is needed to improve stress resistance and shorten the growth period via fast kernel dehydration in intermediate materials of the inbred lines K36, Zhonger/ O2, Lo1125, Han 49, Hua 160, and PH4CV, and further using the selected lines for new combinations.

Abstract
Studying thermotolerance is important for the prevention of thermostress in chickens. This study aimed to analyze the effect of mutations in the heat shock protein 70 (HSP70) gene on chicken thermotolerance. The C.-69A>G SNP in the 5'-flanking region of the HSP70 gene was genotyped in Lingshan and White Recessive Rock (WRR) chickens. Association of this SNP with thermotolerance traits revealed it to be significantly associated with CD4+/CD8+, and potentially associated with heterophil-to-lymphocyte ratio in WRR chickens exposed to thermoneutral temperature (15°C). Online prediction detected a putative myeloid zinc finger protein 1 binding factor in the C.-69A>G mutation. Under acute thermostress, mRNA levels of HSP70 in individuals with different C.-69A>G genotypes varied in the heart, leg muscle, and liver tissues. The HSP70 protein was expressed at higher levels in individuals with the GG genotype than in those with the AA genotype. In heart and liver, protein expression of HSP70 in individuals with the GG genotype was significantly higher than in those with the AA genotype. In leg muscle, protein expression was higher in birds with the GG genotype than in those with the AA and AG genotypes. Luciferase activity of the GG genotype was significantly higher than that of the AA genotype, suggesting that the C.-69A>G SNP regulates HSP70 gene expression. These results indicate that the C.-69A>G SNP in the 5'-flanking region of the HSP70 gene might affect chicken thermotolerance and that the GG genotype might be advantageous for the prevention of thermostress.

Abstract
Copy number variation (CNV) is an important source of genetic variation in organisms and a main factor that affects phenotypic variation. A comprehensive study of chicken CNV can provide valuable information on genetic diversity and facilitate future analyses of associations between CNV and economically important traits in chickens. In the present study, an F2 full-sib chicken population (554 individuals), established from a cross between Xinghua and White Recessive Rock chickens, was used to explore CNV in the chicken genome. Genotyping was performed using a chicken 60K SNP BeadChip. A total of 1,875 CNV were detected with the PennCNV algorithm, and the average number of CNV was 3.42 per individual. The CNV were distributed across 383 independent CNV regions (CNVR) and covered 41 megabases (3.97%) of the chicken genome. Seven CNVR in 108 individuals were validated by quantitative real-time PCR, and 81 of these individuals (75%) also were detected with the PennCNV algorithm. In total, 274 CNVR (71.54%) identified in the current study were previously reported. Of these, 147 (38.38%) were reported in at least 2 studies. Additionally, 109 of the CNVR (28.46%) discovered here are novel. A total of 709 genes within or overlapping with the CNVR was retrieved. Out of the 2,742 quantitative trait loci (QTL) collected in the chicken QTL database, 43 QTL had confidence intervals overlapping with the CNVR, and 32 CNVR encompassed one or more functional genes. The functional genes located in the CNVR are likely to be the QTG that are associated with underlying economic traits. This study considerably expands our insight into the structural variation in the genome of chickens and provides an important resource for genomic variation, especially for genomic structural variation related to economic traits in chickens.

Abstract
The Anyi tile-like gray chicken is a Chinese indigenous breed with a gray dilution phenotype, having gray feathers, comb, skin, shanks, and beak, which is valuable for genetic research on pigmentation. However, the genetic basis of the gray dilution phenotype remains unknown. The objective of this study was to investigate the genetic basis of the gray dilution phenotype in the Anyi tile-like gray chicken. We found that all Anyi tile-like gray chickens tested in this study carried at least one E allele, which is responsible for the appearance of black feathers, and some of them carried the FM allele, which is responsible for the black skin phenotype. A single nucleotide polymorphism (C.1909A>G) was identified within the melanophilin (MLPH) gene and was significantly associated with the gray dilution phenotype. Our findings suggest that the E and FM alleles act together to cause the development of the "five-black" phenotype (black feather, comb, skin, shank, and beak), whereas the MLPH mutation results in defective melanosome transport, leading to the development of the "five-gray" phenotype.

Abstract
PURPOSE Plumbagin, a naphthoquinone constituent of Plumbago zeylanica L. (Plumbaginaceae), is known to exhibit proapoptotic, antiangiogenic and antimetastatic effects in cancer cells. However, the effect of Plumbagin on breast cancer cells and the underlying molecular mechanism has not yet been elucidated. MATERIALS AND METHODS MCF-7 (a human breast cancer cell line) was exposed different concentrations of Plumbagin (PG), and the anti-proliferative activity was evaluated by the MTT assay. The mechanism of action for the growth inhibitory activity of Plumbagin on MCF-7 cancer cells was evaluated using flow cytometry for cell cycle distribution, and western blot for assessment of expression of potential target proteins. RESULTS Plumbagin exhibited a significant anti-proliferative activity against human breast cancer cells. Flow cytometric analysis revealed that Plumbagin caused cell cycle arrest at G1 phase. The cell cycle arrest was well correlated with the inhibition of cyclin D1, cyclin E, and upregulation of tumor suppressor protein p53. It further inhibited the expression of anti-apoptotic Bcl-2 family members such as Bcl-xL and Bcl-2, and activated pro-apoptotic proteins like Bax and Bak. CONCLUSION These findings suggest that the anti-proliferative effect of Plumbagin is due to upregulation of p53 and p21 and suppression of G1 cell cycle regulators.
