Abstract
We searched PubMed, Web of Science, Embase, The Cochrane Library, China Biomedical Literature Database and other databases from inception to June 2023. The included studies were randomised controlled trials (RCT). The studies were screened by four authors, divided into two independent pairs. A total of eighteen studies were included, including 1362 patients, involving twelve intervention measures. The different nutrients had a significant effect on improving blood glucose, reducing inflammation levels and reducing oxidative stress compared with placebo (P < 0.05). Cumulative probability ranking showed that vitamin A + vitamin D + vitamin E ranked first in lowering fasting blood glucose (standardised mean difference (SMD) = 41.30, 95 % CI (2.07, 825.60)) and postprandial 2-h blood glucose (SMD = 15.19, 95 % CI (4.16, 55.53)). In terms of insulin resistance index, the first highest probability ranking is vitamin D (SMD = 5.12, 95 % CI (0.76, 34.54)). In terms of reducing the high-sensitivity C-reactive protein level, the first in probability ranking is VE (SMD = 2.58, 95 % CI (1.87,3.55)). The results of cumulative probability ranking showed that Mg + Zn + Ca + VD ranked first in reducing TNF-α (SMD = 1.90, 95% CI (0.40, 9.08)) and IL-6 (SMD = 1.83, 95 % CI (0.37, 9.12)). In terms of reducing malondialdehyde levels, the first ranked probability is VB1 (SMD = 4.99, 95 % CI (1.85, 13.46)). Cumulative probability ranking results showed that Ca + VD ranked first in reducing total antioxidant capacity (SMD = 0.66,95 % CI (0.38, 1.15)) and glutathione (SMD = 1.39, 95 % CI (0.43, 4.56)). In conclusion, nutritional interventions have significant effects on improving blood glucose, inflammatory levels and oxidative stress in patients with gestational diabetes. Due to the high uncertainty in the results and differences in the number and quality of studies included, the reliability of the conclusions still needs to be validated by conducting large-sample, high-quality RCT studies.

Abstract
BACKGROUND Many smartphone apps designed to assist individuals in managing their weight are accessible, but the assessment of app quality and features has predominantly taken place in Western countries. Nevertheless, there is a scarcity of research evaluating weight management apps in China, which highlights the need for further investigation in this area. OBJECTIVE This study aims to conduct a comprehensive search for the most popular commercial Chinese smartphone apps focused on weight management and assess their quality, behavior change techniques (BCTs), and content-related features using appropriate evaluation scales. Additionally, the study sought to investigate the associations between the quality of various domains within weight management apps and the number of incorporated BCTs and app features. METHODS In April 2023, data on weight management apps from the iOS and Android app stores were downloaded from the Qimai Data platform. Subsequently, a total of 35 weight management apps were subjected to screening and analysis by 2 researchers. The features and quality of the apps were independently assessed by 6 professionals specializing in nutrition management and health behavioral change using the Mobile Application Rating Scale (MARS). Two registered dietitians, who had experience in app development and coding BCTs, applied the established 26-item BCT taxonomy to verify the presence of BCTs. Mean (SD) scores and their distributions were calculated for each section and item. Spearman correlations were used to assess the relationship between an app's quality and its technical features, as well as the number of incorporated BCTs. RESULTS The data set included a total of 35 apps, with 8 available in the Android Store, 10 in the Apple Store, and 17 in both. The overall quality, with a mean MARS score of 3.44 (SD 0.44), showed that functionality was the highest scoring domain (mean 4.18, SD 0.37), followed by aesthetics (mean 3.43, SD 0.42), engagement (mean 3.26, SD 0.64), and information (mean 2.91, SD 0.52), which had the lowest score. The mean number of BCTs in the analyzed apps was 9.17 (range 2-18 BCTs/app). The most common BCTs were "prompt review of behavioral goals" and "provide instruction," present in 31 apps (89%). This was followed by "prompt self-monitoring of behavior" in 30 apps (86%), "prompt specific goal setting" in 29 apps (83%), and "provide feedback on performance" in 27 apps (77%). The most prevalent features in the analyzed apps were the need for web access (35/35, 100%), monitoring/tracking (30/35, 86%), goal setting (29/35, 83%), and sending alerts (28/35, 80%). The study also revealed strong positive correlations among the number of BCTs incorporated, app quality, and app features. This suggests that apps with a higher number of BCTs tend to have better overall quality and more features. CONCLUSIONS The study found that the overall quality of weight management apps in China is moderate, with a particular weakness in the quality of information provided. The most prevalent BCTs in these apps were reviewing behavioral goals, providing guidance, self-monitoring of behavior, goal setting, and offering performance feedback. The most common features were the need for web access, monitoring and tracking, goal setting, and sending alerts. Notably, higher-quality weight management apps in China tended to incorporate more BCTs and features. These findings can be valuable for developers looking to improve weight management apps and enhance their potential to drive behavioral change in weight management.

Abstract
Neuropeptides are key signaling molecules in the endocrine and nervous systems that regulate many critical physiological processes. Understanding the functions of neuropeptides in vivo requires the ability to monitor their dynamics with high specificity, sensitivity, and spatiotemporal resolution. However, this has been hindered by the lack of direct, sensitive, and noninvasive tools. We developed a series of GRAB (G protein-coupled receptor activation‒based) sensors for detecting somatostatin (SST), corticotropin-releasing factor (CRF), cholecystokinin (CCK), neuropeptide Y (NPY), neurotensin (NTS), and vasoactive intestinal peptide (VIP). These fluorescent sensors, which enable detection of specific neuropeptide binding at nanomolar concentrations, establish a robust tool kit for studying the release, function, and regulation of neuropeptides under both physiological and pathophysiological conditions.

Abstract
Oxytocin (OT), a peptide hormone and neuromodulator, is involved in diverse physiological and pathophysiological processes in the central nervous system and the periphery. However, the regulation and functional sequences of spatial OT release in the brain remain poorly understood. We describe a genetically encoded G-protein-coupled receptor activation-based (GRAB) OT sensor called GRABOT1.0. In contrast to previous methods, GRABOT1.0 enables imaging of OT release ex vivo and in vivo with suitable sensitivity, specificity and spatiotemporal resolution. Using this sensor, we visualize stimulation-induced OT release from specific neuronal compartments in mouse brain slices and discover that N-type calcium channels predominantly mediate axonal OT release, whereas L-type calcium channels mediate somatodendritic OT release. We identify differences in the fusion machinery of OT release for axon terminals versus somata and dendrites. Finally, we measure OT dynamics in various brain regions in mice during male courtship behavior. Thus, GRABOT1.0 provides insights into the role of compartmental OT release in physiological and behavioral functions.

Abstract
OBJECTIVE The purpose of this study was to retrospectively assess the efficacy and safety of percutaneous nephrolithotomy (PCNL) for upper urinary stones using upper pole access (UPA) and other (low or middle) pole access (OPA). MATERIALS AND METHODS A comprehensive literature review of articles investigating the clinical efficacy and safety of UPA and OPA was performed. The relevant literature was obtained from PubMed, EMBASE, Science Direct, Google Scholar and the Cochrane Library. The primary outcomes, including the stone-free rate, were evaluated using Review Manager 5.4 software. The secondary outcomes (peri- and postoperative complications and operative date) were also compared and analyzed. RESULTS Ten comparative studies involving 5,290 patients were included in the analysis. The pooled data showed that the UPA group had a stone-free rate (SFR) similar to that of the OPA group [odds ratio (OR) 1.38, 95% confidence interval (CI): 0.94 to 2.03; p=0.22] but a higher incidence of blood transfusion [OR: 1.50; 95% CI: (1.03, 2.19), p=0.04]. There was no statistically significant difference in operative time [mean difference (MD): -7.27; 95% CI: (-25.18, 10.65), p=0.43] or hospital stay [MD: -0.13; 95% CI: (-0.64, 0.37), p=0.60] between the two groups. In addition, the results support that UPA causes fewer complications than OPA. CONCLUSIONS Our findings suggest that UPA and OPA are both effective treatments for the management of upper urinary stones. Compared to OPA, UPA is associated with less need for blood transfusion and fewer complications. Nevertheless, the findings should be further confirmed by well-designed prospective randomized controlled trials (RCTs) with large samples and strict standards.

Abstract
OBJECTIVE To investigate the mechanism by which fibroblasts with high WNT2b expression causes intestinal mucosa barrier disruption and promote the progression of inflammatory bowel disease (IBD). METHODS Caco-2 cells were treated with 20% fibroblast conditioned medium or co-cultured with fibroblasts highly expressing WNT2b, with the cells without treatment with the conditioned medium and cells co-cultured with wild-type fibroblasts as the control groups. The changes in barrier permeability of Caco-2 cells were assessed by measuring transmembrane resistance and Lucifer Yellow permeability. In Caco-2 cells co-cultured with WNT2b-overexpressing or control intestinal fibroblasts, nuclear entry of β-catenin was detected with immunofluorescence assay, and the expressions of tight junction proteins ZO-1 and E-cadherin were detected with Western blotting. In a C57 mouse model of dextran sulfate sodium (DSS)-induced IBD-like enteritis, the therapeutic effect of intraperitoneal injection of salinomycin (5 mg/kg, an inhibitor of WNT/β-catenin signaling pathway) was evaluated by observing the changes in intestinal inflammation and detecting the expressions of tight junction proteins. RESULTS In the coculture system, WNT2b overexpression in the fibroblasts significantly promoted nuclear entry of β-catenin (P < 0.01) and decreased the expressions of tight junction proteins in Caco-2 cells; knockdown of FZD4 expression in Caco-2 cells obviously reversed this effect. In DSS-treated mice, salinomycin treatment significantly reduced intestinal inflammation and increased the expressions of tight junction proteins in the intestinal mucosa. CONCLUSION Intestinal fibroblasts overexpressing WNT2b causes impairment of intestinal mucosal barrier function and can be a potential target for treatment of IBD.

Abstract
The surface glycoprotein (S protein) of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was used to develop coronavirus disease 2019 (COVID-19) vaccines. However, SARS-CoV-2, especially the S protein, has undergone rapid evolution and mutation, which has remained to be determined. Here, we analyzed and compared the early (12 237) and the current (more than 10 million) SARS-CoV-2 strains to identify the mutation features and geographical distribution of the S gene and S protein. Results showed that in the early strains, most of the loci were with relative low mutation frequency except S: 23403 (4486 strains), while in the current strains, there was a surge in the mutation strains and frequency, with S: 23403 constantly being the highest one, but tremendously increased to approximately 1050 times. Furthermore, D614 (S: 23403) was one of the most highly frequent mutations in the S protein of Omicron as of March 2022, and most of the mutant strains were still from the United States, and the United Kingdom. Further analysis demonstrated that in the receptor-binding domain, most of the loci with low mutation frequency in the early strains, while S: 22995 was nowadays the most prevalent loci with 3 122 491 strains in the current strains. Overall, we compare the mutation features of the S region in SARS-CoV-2 strains between the early and the current stains, providing insight into further studies in concert with emerging SARS-CoV-2 variants for COVID-19 vaccines.

Abstract
Objective: To explore the value of a nomogram based on clinical data and enhanced CT radiomics in the prediction of Epstein-Barr virus-associated gastric carcinoma(EBVaGC). Methods: The data of 136 patients, including 100 males and 36 females, aged [M (Q1, Q3)] 65 (53, 71) years, with gastric cancer confirmed by surgery and pathology were retrospectively analyzed. According to Epstein-Barr virus-encoded small RNA (EBER) in situ hybridization, those patients were divided into Epstein-Barr virus (EBV) positive group (n=32) and EBV negative group (n=104). All patients underwent multi-phase enhanced CT scanning before surgery and randomly assigned to the training group (n=95) and validation group (n=41) in a ratio of 7︰3. MaZda software was used to extract radiomics features of enhanced CT images. The intra-group correlation coefficient (ICC), variance analysis and minimum absolute shrinkage and selection algorithm (LASSO) regression were used to reduce the dimensionality of the radiomics features, and then the radiomics score (Radscore) was calculated. The nomogram model was based on combined clinical data, morphological features and Radscore. The predictive power of the nomogram was evaluated according to the area under the receiver operating characteristic curve (AUC), and the net clinical benefit of the nomogram was evaluated by the decision curve and calibration curves were drawn according to the data of the training group and the validation group to analyze the consistency of the nomogram model. Results: After selection, six optimal radiomics features were obtained, including Mean, Skewness, S(1, 0) Sum entropy, S(1, 1) Contrast, 99% percentile and S(2, 2)Angular second moment. Radscore of EBV positive group were higher than that of the EBV negative group (training group: 3.78±0.83 vs 2.80±0.98; validation group: 3.81±0.47 vs 2.94±0.95) (both P<0.05) both in the training group and validation group. The AUC of the radiomics model in training group and validation group were 0.773(95%CI:0.612-0.962)and 0.792(95%CI:0.597-0.927)respectively,and the sensitivity and specificity were 63.6% and 93.1%, 70.0% and 87.1%, respectively. The AUC of the nomogram model based on clinical data and radiomics in the training group and the validation group were 0.883(95%CI:0.644-0.984) and 0.851(95%CI:0.715-0.996), respectively. The nomogram model showed superior predictive performance (both P<0.05). Conclusion: The nomogram model based on clinical data and radiomics has better efficacy in the prediction of Epstein-Barr virus associated gastric cancer.

Abstract
INTRODUCTION We explored the association between clinical outcomes and the cleavage rate of day-3 cleavage slow-growing embryos after overnight culture. METHODS The data collected from 303 frozen embryo transfer (FET) cycles with 606 4-cell or 5-cell embryos cultured overnight (18-22 h) after thawing were analyzed. Based on the growth rate after the overnight culture, the embryos were divided into three groups: no embryo reaching eight cells (Group I), either one of the two embryos reaching eight cells (Group II), and both two embryos reaching eight cells or more (Group III). A statistical analysis of the different clinical outcomes from the three groups was performed. RESULTS Biochemical pregnancy rate (OR 3.22; p = 0.001), implantation rate (OR 2.44; p = 0.002), clinical pregnancy rate (OR 3.04; p = 0.001), ongoing pregnancy rate (OR 3.14; p = 0.001), and live birth rate (OR 2.78; p = 0.004) were significantly higher in Group III as compared to Group I. Group II had a significantly higher biochemical pregnancy rate (OR 2.02; p = 0.013) and implantation rate (OR 1.77; p = 0.019) than Group I. CONCLUSIONS The capability of day-3 cleavage slow-growing embryos to reach eight cells, especially that of two embryos reaching eight cells by overnight culture, appear to result in a better pregnancy outcome.

Abstract
PURPOSE To evaluate optimal warming time, the early warming or the routine warming time, for transferring vitrified-warmed and cultured overnight cleavage stage of the slow-growing embryos on day 3 in frozen embryo transfer (FET) cycle. METHODS This was a retrospective cohort study from January 2017 to July 2018. A total of 705 FET patients aged < 40 years were included and 1486 embryos were formed, of which 1366 embryos were eventually transferred. RESULTS For slow-growing embryos, the clinical pregnancy rate of early warming group [152/468 (32.5%)] was significantly higher than that of routine warming group (55/235 (23.4%)) [OR 1.39 (CI 1.06-1.81), p = 0.01], while there was no statistically significant difference in pregnancy loss in early warming group [39/170 (22.9%)] versus in routine warming group [16/62 (25.8%)] [OR 0.89 (CI 0.53-1.47), p = 0.65]. CONCLUSION For slow-growing embryos, higher pregnancy outcomes were shown in early warming strategy as compared to the routine warming, which suggested that the improvement of endometrium-embryo synchronism may correct the time difference brought by the slow-growing embryos.

Abstract
Background rs13405728 was identified as one of the most prevalent susceptibility loci for polycystic ovary syndrome (PCOS) in Han Chinese and Caucasian women. However, the target genes and potential mechanisms of the rs13405728 locus remain to be determined. Methods Three-dimensional (3D) genome interactions from the ovary tissue were characterized via high-through chromosome conformation capture (Hi-C) and Capture Hi-C technologies to identify putative targets at the rs13405728 locus. Combined analyses of eQTL, RNA-Seq, DNase-Seq, ChIP-Seq, and sing-cell sequencing were performed to explore the molecular roles of these target genes in PCOS. PCOS-like mice were applied to verify the expression patterns. Results Generally, STON1 and FSHR were identified as potential targets of the rs13405728 locus in 3D genomic interactions with epigenomic regulatory peaks, with STON1 (P=0.0423) and FSHR (P=0.0013) being highly expressed in PCOS patients. STON1 co-expressed genes were associated with metabolic processes (P=0.0008) in adipocytes (P=0.0001), which was validated in the fat tissue (P<0.0001) and ovary (P=0.0035) from fat-diet mice. The immune system process (GO:0002376) was enriched in FSHR co-expressed genes (P=0.0002) and PCOS patients (P=0.0002), with CD4 high expression in PCOS patients (P=0.0316) and PCOS-like models (P=0.0079). Meanwhile, FSHR expression was positively correlated with CD4 expression in PCOS patients (P=0.0252) and PCOS-like models (P=0.0178). Furthermore, androgen receptor (AR) was identified as the common transcription factor for STON1 and FSHR and positively correlated with the expression of STON1 (P=0.039) and FSHR (P=4e-06) in ovary tissues and PCOS-like mice. Conclusion Overall, we identified STON1 and FSHR as potential targets for the rs13405728 locus and their roles in the processes of adipocyte metabolism and CD4 immune expression in PCOS, which provides 3D genomic insight into the pathogenesis of PCOS.

Abstract
Human papillomavirus (HPV) infection and gene mutations were reputed as key factors in cervical carcinoma (CC) and head and neck squamous cell carcinoma (HNSCC). However, the associations of HPV status and gene mutations remain to be determined. This study aims to identify molecular patterns of LRP1B mutation and HPV status via rewiring tumor samples of HNSCC (n=1478) and CC (n=178) from the TCGA dataset. Here, we found that LRP1B mutation was associated with HPV status in CC (P=0.040) and HNSCC (P=0.044), especially in HPV 16 integrated CC (P=0.036). Cancer survival analysis demonstrated that samples with LRP1B mutation showed poor disease outcomes in CC (P=0.013) and HNSCC (P=0.0124). In addition, the expression status of LPR1B was more favorable for prediction than TP53 or RB1 in CC and HNSCC. Mutation clustering analysis showed that samples with LRP1B mutation showed higher mutation count in CC (P=1.76e-67) and HNSCC (P<10e-10). Further analysis identified 289 co-occurrence genes in these two cancer types, which were enriched in PI3K signaling, cell division process, and chromosome segregation process, et al. The 289-co-occurrence gene signature identified a cluster of patients with a higher portion of copy number variation (CNV) lost in the genome, different tumor HPV status (P<10e-10), higher mutation count (P<10e-10), higher fraction genome altered value (P=2.078e-4), higher aneuploidy score (P=3.362e-4), and earlier started the smoking year (P=2.572e-4), which were associated with shorter overall survival (P=0.0103) in CC and HNSCC samples. Overall, LRP1B mutation was associated with tumor HPV status and was an unfavorable prognostic biomarker for CC and HNSCC.

Abstract
BACKGROUND The gonadotrophin-releasing hormone agonist (GnRHa) has gained widespread popularity of achieving pituitary suppression before ovarian stimulation with exogenous gonadotropins in assisted reproductive technology protocols. However, a very small part of patients may develop ovarian hyperresponse after the sole administration of GnRHa without gonadotropins. CASE REPORT A 32-year-old female diagnosed with polycystic ovary syndrome presented for her second IVF cycle in our reproductive center. Twenty-eight days after 3.75mg triptorelin was administrated on day 2 of her menstrual cycle, bilateral ovaries were significantly enlarged and presented multiple cystic masses. The hormone profile was as follows: E2>4870pg/ml, P 13.19ng/ml, FSH 14IU/L, and LH 10.77IU/L. The patient felt symptoms of mild ovarian hyperstimulation syndrome. In the subsequent IVF treatment cycle, antagonist protocol was performed. It showed that follicles developed slowly and exogenous gonadotropins were used for 13 days. Finally, seven oocytes were obtained and only one blastocyst graded 4BC formed. CONCLUSION Ovarian hyperstimulation following the sole administration of GnRHa can be occurred, but the mechanism is still not yet clear. Antagonist protocol may be an alternative fertility strategy, but the risk of poor embryo quality and low pregnancy rate of transplantation should be warned.

Abstract
This meta-analysis was intended to evaluate the effects of intrauterine perfusion of peripheral blood mononuclear cells (PBMC) on the pregnancy outcomes including clinical pregnancy rates, embryo implantation rates, live birth rates and miscarriage rates of infertile women who were undergoing in vitro fertilisation (IVF) treatment. By searching Pubmed, Embase database, five articles meeting the inclusion criteria were included, and 1173 women were enrolled (intrauterine PBMC group: n = 514; NO-PBMC group: n = 659). For the entire IVF/ICSI population and one or two embryo transfer failure patients, there was no significant difference in endometrial thickness, embryo implantation rates, live birth rates, and miscarriage rates between the PBMC group and NO-PBMC group. Although the clinical pregnancy rates of the PBMC group were higher than that of the NO-PBMC group, the confidence interval was close to the line of unity. As for the patients with three or more implantation failures, the clinical pregnancy rates, embryo implantation rates and live birth rates were much higher in the PBMC group than that of the NO-PBMC group. In summary, current evidence suggests that intrauterine perfusion of PBMC can significantly improve pregnancy outcomes in patients who have three or more implantation failures.Impact statementWhat is already known on this subject? An increasing number of studies have shown that immune cells play an important role in embryo transfer. There is no reliable evidence to confirm the clinical efficacy of intrauterine perfusion of PBMC.What do the results of this study add? The current evidence suggests that intrauterine perfusion of PBMC can significantly improve pregnancy outcomes in patients who have three or more implantation failures.What are the implications of these findings for clinical practice and/or further research? To the best of our knowledge, this meta-analysis is the first to evaluate the effect of intrauterine perfusion of PBMC on pregnancy outcomes before embryo transfer. Our study indicated that intrauterine perfusion of PBMC significantly increased clinical pregnancy rates, embryo implantation rates, and live birth rates in patients who failed more than three implants.

Abstract
BACKGROUND Salpingectomy is routinely performed in ectopic pregnancy (EP). However, the effect of the surgery on the ovarian reserve and ovarian response in EP patients is still uncertain and has not been systematically evaluated. Therefore, we conducted this meta-analysis to provide a comparison of the ovarian reserve and ovarian response between the pre-salpingectomy and post-salpingectomy in EP patients. METHODS Pubmed, Embase, and Cochrane Library were searched for all relevant articles published up to December 2018. We retrieved the basic information and data of the included studies. The data was analyzed by Review Manager 5.3 software (Cochrane Collaboration, Oxford, UK). RESULTS A total of 243 articles were extracted from the databases, and 7 studies were included in the meta-analysis. The ovarian reserve including anti-Mullerian hormone (inverse variance [IV] -0.7 [95% confidence interval [CI] -0.63, 0.49]), antral follicle count (IV 1.7 [95% CI -2.02, 5.42]) and basal follicle stimulating hormone (IV 0.02 [95% CI -0.63, 0.68]) was comparable between the pre-salpingectomy group and the post-salpingectomy group. The amount of gonadotropin was significantly higher in the post-salpingectomy group when compared with that in the pre-salpingectomy group (IV -212.65 [95% CI -383.59, -41.71]). There was no significant difference in the left parameters of the ovarian response including the duration of gonadotropin stimulation (IV -0.32 [95% CI -0.76, 0.12]), the estrogen level on the human chorionic gonadotropin triggering day (IV -4.12 [95% CI -236.27, -228.04]) and the number of retrieved oocytes (IV 0.35 [95% CI -0.76, 1.46]) between 2 groups. CONCLUSIONS The current results suggest that salpingectomy has no negative effect on the ovarian reserve and ovarian response.

Abstract
At present, the precise role of human menopausal gonadotropin (HMG) and recombinant luteinizing hormone (rLH) supplementation at an early time of follicular phase on in vitro fertilization (IVF)/intra cytoplasmatic sperm injection (ICSI) outcomes remains uncertain.Here infertile women of normal ovarian function undergoing their first cycle of IVF/ICSI were studied and were randomly allocated into 3 groups. Group 1, ovarian stimulation with 150IU recombinant follicle-stimulating hormone (FSH) alone. Group 2, patients received 75IU rFSH and 75IU HMG. Group 3 patients were given 150IU rFSH and 75IU rLH.There were no significant differences in the clinical characteristics, ovarian response, the biochemical, clinical and ongoing pregnancy rates among the 3 groups. No significant differences were found in biochemical, clinical and ongoing pregnancy rates between the patients whose LH levels were lower than 0.75 mIU/ml and those above this threshold in group 1. Furthermore, there were also no significant differences in biochemical, clinical and ongoing pregnancy rates among the 3 group patients whose LH level lower than 0.75 mIU/ml.The results showed that either the addition of HMG or rLH supplementation at an early time of follicular phase produce no significant benefit on IVF outcome in patients with normal ovarian function.

Abstract
OBJECTIVE To investigate the role of cortistatin (CST) on cyclosporine A (CsA)-induced myocardial apoptosis in rats and determine its effect on the expressions of myocardial apoptosis genes. MATERIALS AND METHODS H9C2 cells were treated with different concentrations of CsA solution (0.04, 0.2, 1 and 5 μM) for 24, 48 and 72 h, respectively. The cell viability was detected via methyl thiazolyl tetrazolium (MTT) assay, and the appropriate dose and time were compared and determined. At the same time, CST in different concentrations (0.08, 0.04, 0.2, 1, 5 and 25 μM) was added into cell culture, and the appropriate dose was identified using MTT assay. The cellular morphology in each group was observed, and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining was performed for the detection of cell apoptosis. Moreover, in molecular mechanism research, the apoptosis-associated factors, factor associated suicide (Fas), Fas ligand (FasL) and B-cell lymphoma-2-associated X protein (Bax), were detected via quantitive Real-time polymerase chain reaction (qPCR). Finally, the levels of a protein related to myocardial apoptosis in rats were investigated via Western blotting. RESULTS The treatment with 1 μM CsA for 48 h caused significant apoptosis. The results of TUNEL staining showed the inhibitory role of CST on the myocardial apoptosis in rats induced by CsA. The detection of apoptosis factors via Real-time PCR revealed that after the induction of CsA, the expressions of Fas, FasL and Bax mRNA in cells were significantly higher than those in control group, but were significantly decreased after administration of CST. Western blotting showed that the protein expressions of Caspase 3 and Caspase 9 were remarkably elevated in cells after the use of CsA, but were significantly reduced after administration of CST (p < 0.01). CONCLUSIONS CST contributes to antagonistic function against the CsA-induced apoptosis of rat myocardial cells, and its effect is related to the down-regulation of expressions of apoptotic factors, Fas, FasL, Bax, Caspase 3, and Caspase 9.

Abstract
OBJECTIVE This study aimed to explore the prevalence and determinants of genitourinary syndrome of menopause (GSM) in Chinese mid-life women. METHODS A cross-sectional single-center study was performed among 40-65-year-old women who participated in physical examinations at Shanghai Jiao Tong University Affiliated Sixth People's Hospital from December 2015 to December 2016. The participating women were questioned about their genitourinary symptoms, and the relationships between these symptoms and the women's demographic characteristics were evaluated. RESULTS The prevalence of GSM was 30.8%, the most frequent symptom was decreased sexual desire (18.4%), and the frequency of vulvovaginal symptoms and lower urinary tract symptoms was 17.5% and 14.8%, respectively. In addition, most of the symptoms were mild. In postmenopausal women, the prevalences of GSM and the three aforementioned symptoms were higher than those in perimenopausal women (p < 0.05). Based on binary logistic regression analysis, GSM was found to be associated with postmenopause (p = 0.007; odds ratio (OR) 1.52), at least two abortions (p = 0.035; OR 1.42), body mass index (BMI) ≥ 30 kg/m2 (p = 0.032; OR 1.91) and diabetes (p = 0.041; OR 1.94). CONCLUSIONS GSM is common in Chinese mid-life women, and associations between GSM and postmenopause, abortion, BMI and diabetes were identified. Health-care practitioners should actively discuss urogenital symptoms with middle-aged female patients and take appropriate interventions to improve the health of their urogenital tract and quality of life.

Abstract
Objective: To evaluate the association between single nucleotide polymorphisms (SNPs) of RS1826690 located in UGT2B4 gene and pathological complete response (pCR) to neoadjuvant chemotherapy in breast cancer patients. Methods: A total of 146 breast cancer patients were enrolled to detect the SNPs of RS1826690 by sequenom. The relationship between SNPs of RS1826690 and pCR, predictors of pCR were analyzed by univariate or multivariate analysis. Results: The frequency of CC, CT and TT genetype of RS1826690 was 20.6%, 39.7% and 39.7%, respectively. Of the 171 patients, pCR was achieved in 39 cases (26.7%), with CC allele in 14 cases, CT allele in 7 cases and TT allele in 18 cases, and statistically significant difference was observed (χ(2)=16.684, P=0.003). Multivariate logistic regression analysis showed that SNPs of RS1826690 was an independent predictor of pCR (95% CI: 2.311-28.810, P=0.001) . SNPs of RS1826690 was statistically associated with estrogen receptor (ER) status (χ(2)=7.872, P=0.020). Conclusion: SNPs of RS1826690 was associated with pCR, and breast cancer patients with CC allele were more likely to achieve pCR.

Abstract
Controlled and compacted TiAl3 coating was successfully fabricated on the network structured TiBw/Ti6Al4V composites by hot-dipping aluminum and subsequent interdiffusion treatment. The network structure of the composites was inherited to the TiAl3 coating, which effectively reduces the thermal stress and avoids the cracks appeared in the coating. Moreover, TiB reinforcements could pin the TiAl3 coating which can effectively improve the bonding strength between the coating and composite substrate. The cycle oxidation behavior of the network structured coating on 873 K, 973 K and 1073 K for 100 h were investigated. The results showed the coating can remarkably improve the high temperature oxidation resistance of the TiBw/Ti6Al4V composites. The network structure was also inherited to the Al2O3 oxide scale, which effectively decreases the tendency of cracking even spalling about the oxide scale. Certainly, no crack was observed in the coating after long-term oxidation due to the division effect of network structured coating and pinning effect of TiB reinforcements. Interfacial reaction between the coating and the composite substrate occurred and a bilayer structure of TiAl/TiAl2 formed next to the substrate after oxidation at 973 K and 1073 K. The anti-oxidation mechanism of the network structured coating was also discussed.

In the composites, Ti phase is distributed continuously by sintering necks, while Mg phase is also continuous, distributing at the interconnected pores surrounding the Ti phase. The results showed that the fabricated Ti-Mg composites exhibited low modulus and high strength, which are very suitable for load bearing biomedical materials. The composites with 100 µm and 230 µm particle sizes exhibited Young's modulus of 37.6 GPa and 23.4 GPa, 500.7 MPa and 340 MPa of compressive strength and 631.5 MPa and 375.2 MPa of bending strength, respectively. Moreover, both of the modulus and strength of the composites increase with decreasing of Ti particle sizes. In vitro study has been done for the preliminary evaluation of the Ti-Mg composites.

Abstract
OBJECTIVE To explore the correlation of body composition with the severity of menopausal symptoms, as well as each classic menopausal symptom. METHODS A total of 758 (peri-)menopausal women were recruited (aged from 40 to 67 years) from the Menopause Clinic in the Shanghai Sixth People's Hospital. Different regions of fat mass, lean mass and fat-free mass were measured by bioelectrical impedance analysis, while menopausal symptoms were evaluated by valid modified Kupperman's index (KMI) in the Chinese version. RESULTS After adjusting for potential confounders, logistic regression revealed that trunk lean mass (odds ratio 0.29, 95% confidence interval 0.09-0.99) was the independent determinant of moderate to severe menopausal symptoms (KMI ≥ 16). In multiple regression analysis, significant relationships were found between body mass index and hot flushes/sweating and diabetes (p < 0.05). There was a significant relationship between lean mass and muscle/joint pain and sexual problems (p < 0.05). We also observed significant relationships between fat mass and hot flushes/sweating and muscle/joint pain. CONCLUSIONS Our findings indicated that trunk lean mass was an independent protective factor for moderate to severe menopausal symptoms. Strengthening the trunk lean mass may alleviate menopausal symptoms.

Abstract
Objective: To understand the prevalence of facility-based HIV testing and its associated factors among men who have sex with men (MSM) in Beijing city. Methods: An application-based cross-sectional survey was employed to understand HIV site test situation and associated factors. The survey was carried out from May 14(th) to 21(st), 2016. Users of a smart phone application for gay dating were recruited and those eligible for this survey were investigated with an online self-administered questionnaire. Information of demographics, sexual behaviors, facility-based HIV testing history and recreational drug abuses were collected. The multivariate logistic regression was used to make comparison among different groups and assess associated factors. Results: A total of 7 494 participants were enrolled in the survey with mean age of (28.81 ± 7.38) years, 87.14% (6 530/7 494) sought sexual partners through internet. The proportion of facility-based HIV testing in 1 year was 42.55% (3 189/7 494), MSM who were 25-29 years had higher proportion of facility-based HIV testing in 1 year, the proportion was 45.56%(1 104/2 423). Among MSM who could insist in using condom during anal sex (50.46% (1 539/3 050)), the proportion of HIV site testing in 1 year was higher. The MSM who reported seeking healthcare for symptoms of a sexually transmitted infections (STIs) in the past year or ever using recreational drug had higher proportion of facility-based HIV testing, the proportions were 56.81% (409/720) and 52.00% (1 340/4 917), respectively. Compared with alone cohabitation, cohabitating was associated with decreased odds of HIV facility-based testing in past 1 year(odds ratio (OR)= 0.79, P<0.001). Compared with homosexual sexual orientation, bisexual sexual orientation was associated with decreased odds of facility-based HIV testing (OR=0.83, P=0.004). With the increasing of number of male anal sex partners, the odds of HIV facility-based testing was increasing (OR=1.31, P<0.001) But with the decreasing of the frequency of condom using with male anal sex partners, the odds of facility-based HIV testing was decreasing (OR=0.85, P=0.014). Using recreational drugs (OR=1.36, P<0.001) and seeking healthcare for symptoms of a STI in the past 1 year (OR=1.73, P<0.001) were associated with decreased odds of HIV site testing. Conclusion: MSM in Beijing had lower proportion of facility-based HIV testing in past 1 year. Multiple anal sex partners, using recreational drugs, seeking healthcare for symptoms of a STI in the past year, cohabitating, bisexual sexual orientation, and lower frequency of condom using with male anal sex partners were associated with the odds of HIV facility-based testing in past 1 year.

Abstract
Objective: To explore the outcome of trial of labor after cesarean section(TOLAC). Methods: Totally 614 TOLAC were conducted in the First Affiliated Hospital of Kunming Medical University from July 2013 to June 2016. Among them, 586 cases of singleton pregnancy with one prior cesarean section(gestational age≥28 weeks)were studied retrospectively. The maternal and neonatal outcomes among the vaginal birth after cesarean(VBAC)group(481 cases), failed TOLAC group(105 cases)and the elective repeat cesarean section(ERCS)group(1 145 cases)were compared. Multiple logistic regression was used to determine the risk factors of admission to neonatal intensive care unit(NICU). Results: (1)The TOLAC rate was 29.62%(614/2 073)from July 2013 to June 2016, and the VBAC rate was 82.6%(507/614). The cesarean section rate was reduced by VBAC by 3.147%(507/16 112).(2)The comparison of adverse maternal outcomes: in the VBAC group, the postpartum hemorrhage volume was(431±299)ml, the rate of postpartum fever was 6.4%(31/481), the birth weight of the neonates was(3 085± 561)g, and the rate of large for gestational age was 2.9%(14/481). All were significantly lower than those in the failed TOLAC group and the ERCS group(P<0.05). There was no significant difference in other adverse maternal outcomes[the uterine rupture rate(0.2% ,1/481), the bladder injury rate(0), the proportion of postpartum hemorrhage volume≥1 500 ml(1.0%, 5/481), the blood transfusion rate(3.7%, 18/481)]and adverse perinatal outcomes[the rate of neonatal 5-minute Apgar score<7(0.4%, 21/481), the rate of umbilical arterial pH<7.0(0.6% , 3/481), the rate of the NICU admission and the perinatal mortality rate(12.3%, 59/481)]among the 3 groups(P>0.05). Multiple logistic regression showed no association between VBAC and admission to the NICU(OR=0.84, 95%CI: 0.58-1.21). The isolated risk factors for admission to the NICU were preterm birth(OR=16.71, 95% CI: 11.44-24.40), hypertensive disorder complicating pregnamcy(OR=3.89, 95% CI: 2.39-6.35), meconium stained amniotic fluid(OR=2.48, 95% CI: 1.62-3.80), small for gestational age(OR=2.00, 95% CI: 1.19-3.36)and diabetes mellitus(OR=1.69, 95% CI: 1.14-2.50). Conclusions: VBAC reduces cesarean section rate, with good outcomes in both mother and neonate. It is a safe and feasible way of labor in women with only one cesarean section history.

Abstract
Background: Ghrelin is the only orexigenic hormone known to stimulate food intake and promote obesity and insulin resistance. We recently showed that plasma ghrelin is controlled by butyrylcholinesterase (BChE), which has a strong impact on feeding and weight gain. BChE knockout (KO) mice are prone to obesity on high-fat diet, but hepatic BChE gene transfer rescues normal food intake and obesity resistance. However, these mice lack brain BChE and still develop hyperinsulinemia and insulin resistance, suggesting essential interactions between BChE and ghrelin within the brain. Methods: To test the hypothesis we used four experimental groups: (1) untreated wild-type mice, (2) BChE KO mice with LUC delivered by adeno-associated virus (AAV) in combined intravenous (i.v.) and intracerebral (i.c.) injections, (3) KO mice given AAV for mouse BChE (i.v. only) and (4) KO mice given the same vector both i.v. and i.c. All mice ate a 45% calorie high-fat diet from the age of 1 month. Body weight, body composition, daily caloric intake and serum parameters were monitored throughout, and glucose tolerance and insulin tolerance tests were performed at intervals. Results: Circulating ghrelin levels dropped substantially in the KO mice after i.v. AAV–BChE delivery, which led to normal food intake and healthy body weight. BChE KO mice that received AAV–BChE through i.v. and i.c. combined treatments not only resisted weight gain on high-fat diet but also retained normal glucose and insulin tolerance. Conclusions: These data indicate a central role for BChE in regulating both insulin and glucose homeostasis. BChE gene transfer could be a useful therapy for complications linked to diet-induced obesity and insulin resistance.

Abstract
Molecular targeting is an import strategy to treat advanced colon cancer. The current study demonstrates that expression of GRM3, a metabotropic glutamate receptor mainly expressed in mammalian central nervous system, is significantly upregulated in majority of human colonic adenocarcinomas tested and colon cancer cell lines. Knockdown of GRM3 expression or inhibition of GRM3 activation in colon cancer cells reduces cell survival and anchorage-independent growth in vitro and inhibits tumor growth in vivo. Mechanistically, GRM3 antagonizes TGFβ-mediated activation of protein kinase A and inhibition of AKT. In addition, TGFβ signaling increases GRM3 protein stability and knockdown of GRM3 enhances TGFβ-mediated tumor suppressor function. Further studies indicate that miR-487b-3p directly targets GRM3. Overexpression of miR-487b-3p mimics the effects of GRM3 knockdown and suppresses the tumorigenicity of colon cancer cells in vivo. Expression of miR-487b-3p is decreased in colon adenocarcinomas and inversely correlates with GRM3 expression. Taken together, these studies indicate that upregulation of GRM3 expression is a functionally important molecular event in colon cancer, and that GRM3 is a promising molecular target for colon cancer treatment. This is particularly interesting and important from a therapeutic standpoint because numerous metabotropic glutamate receptor antagonists are available, many of which have been found unsuitable for treatment of neuropsychiatric disorders for reasons such as inability to readily penetrate blood brain barriers. Since GRM3 is upregulated in colon cancer, but rarely expressed in normal peripheral tissues, targeting GRM3 with such agents would not likely cause adverse neurological or peripheral side effects, making GRM3 an attractive and specific molecular target for colon cancer treatment.

Abstract
We present a new class of TiBw/Ti6Al4V composites with a network reinforcement architecture that exhibits a significant creep resistance compared to monolithic Ti6Al4V alloys. Creep tests performed at temperatures between 773 K and 923 K and stress range of 100 MPa-300 MPa indicate both a significant improvement of the composites creep resistance due to the network architecture made by the TiB whiskers (TiBw), and a decrease of the steady-state creep rates by augmenting the local volume fractions of TiBw in the network region. The deformation behavior is driven by a diffusion-controlled dislocation climb process. Moreover, the activation energies of these composites are significantly higher than that of Ti6Al4V alloys, indicating a higher creep resistance. The increase of the activation energy can be attributed to the TiBw architecture that severely impedes the movements of dislocation and grain boundary sliding and provides a tailoring of the stress transfer. These micromechanical mechanisms lead to a remarkable improvement of the creep resistance of these networked TiBw/Ti6Al4V composites featuring the special networked architecture.

Abstract
Novel Ti6Al4V alloy matrix composites with a controllable two-scale network architecture were successfully fabricated by reaction hot pressing (RHP). TiB whiskers (TiBw) were in-situ synthesized around the Ti6Al4V matrix particles, and formed the first-scale network structure (FSNS). Ti5Si3 needles (Ti5Si3) precipitated in the β phase around the equiaxed α phase, and formed the secondary-scale network structure (SSNS). This resulted in increased deformation compatibility accompanied with enhanced mechanical properties. Apart from the reinforcement distribution and the volume fraction, the ratio between Ti5Si3 and TiBw fraction were controlled. The prepared (Ti5Si3 + TiBw)/Ti6Al4V composites showed higher tensile strength and ductility than the composites with a one-scale microstructure, and superior wear resistance over the Ti6Al4V alloy under dry sliding wear conditions at room temperature.

Abstract
Purpose
The purpose of this paper is to build a research model from the perspectives of entrepreneur and entrepreneurial opportunity examining the effects of entrepreneurial growth aspiration and the innovativeness of entrepreneurial opportunity and their interactive effect on the business planning in the new venture emergence.
Design/methodology/approach
Six hypotheses are put forward and examined by hierarchical multiple linear regression and multiple logistic regression. The data of this paper are based on the first two rounds of survey data from Chinese Panel Study of Entrepreneurial Dynamics.
Findings
The empirical results show that entrepreneurial growth aspiration has significant positive effects on the business planning, namely, compared to the comfortable size entrepreneurs, the growth-oriented entrepreneurs are more likely to do the business planning in the new venture emergence. Different from prior discoveries, the innovativeness of opportunity has no effect on the business planning, but it positively influences the time of doing business planning, and entrepreneurial growth aspiration has a positive moderate effect on this relationship.
Research limitations/implications
Entrepreneurial growth aspiration in this paper is divided into growth-oriented entrepreneur and comfortable size entrepreneur from the single perspective of scale. Future research should define growth aspiration as a continuous variable in light of several dimensionalities.
Practical implications
The findings are useful for entrepreneurs to make rational and effective decisions whether to do business planning and when to do on the basis of their growth aspiration and the innovativeness of opportunity. The growth-oriented entrepreneur should do the business planning in the new venture emergence. The higher innovative the opportunity is, the latter the entrepreneur had better do the business planning. Besides, it provides the theoretical foundation for entrepreneurship training courses about business planning offered by governments, educational institutions and social training institutions.
Originality/value
This paper absorbs growth aspiration into the analysis framework about business planning based on expectancy theory, making up for deficiencies that prior researches excessively focus on entrepreneurial experience and opportunity. Additionally, the study will inspire scholars to research the mechanism of action relative to business planning from the interactive relationship between entrepreneur and entrepreneurial opportunity.

Abstract
Numerous studies have evaluated the association between the 341C/T polymorphism in glutathione S-transferase P1 (GSTP1) and lung cancer risk. However, there are conflicting results from previous studies. To derive a more precise estimation of the association, we conducted this meta-analysis. A comprehensive search was conducted to identify the eligible studies examining the GSTP1 341C/T polymorphism and lung cancer risk. We used odds ratios (ORs) with 95% confidence intervals (CIs) to assess the strength of the association. The meta-analysis results showed that the GSTP1 341C/T polymorphism was significantly associated with lung cancer risk (TT vs CC: OR = 3.33, 95%CI = 1.49-7.44; CT vs CC: OR = 1.35, 95%CI = 1.10-1.65; dominant model: OR = 1.43, 95%CI = 1.05-1.96; recessive model: OR = 0.31, 95%CI = 0.14-0.70). The results indicate that the GSTP1 341C/T polymorphism may contribute to lung cancer risk. Conclusive evidence on the effects of this variant in lung cancer should be addressed in further studies.

Abstract
OBJECTIVE To comparatively observe the effects of 20(R)-ginsenoside Rg3 and PEG-PLGA-Rg3 nanoparticles on the Lewis lung cancer mice and to explore the mechanisms of Rg3 and PEG-PLGA-Rg3 nanoparticle anti-cancer in vivo. METHODS Lewis lung cancer mouse model was established and 60 mice were randomly divided into 5 groups with twelve in each group: PEG-PLGA-Rg3 nanoparticles group(Rg3-N), PEG-PLGA group (PEG), Rg3 group (Rg3), normal control group(C), saline control group(NS), and received intragastric administration for 14 days. The weights of the mice were measured every 2 days and the weight curves were obtained. At the same time, the color pattern, activity and mental status were observed. The mice were sacrificed when the administration was over, and the effects of 20(R)-ginsenoside Rg3 and PEG-PLGA-Rg3 nanoparticles on tumor weight, and the tumor:weight ratios were analysed. In addition, the tumor microvessel density (MVD) was measured by immunohistochemical staining with anti-CD31 antibody to compare the effects of Rg3 and PEG-PLGA-Rg3 nanoparticles on the tumor angiogenesis in vivo. Furthermore, the levels of such angiogenesis and proliferation factors as MMP-9, HIF-1α, VEGF, Ki-67 were examined by RT-PCR, Western blot and immunohistochemistry to explore the internal molecular mechanisms of anti-tumor effects in vivo. RESULTS The trends of variation of the mice weights in NS group and PEG group were rising early but declining later. In contrast, the trends of the other three groups were rising early and became stable later. In comparison with NS group, the mice of Rg3 group and Rg3-N group had better general status: brighter color, more active and better spirit. Compared with NS group,the tumor weight in PEG group, Rg3 group and Rg3-N group showed no significant difference but the tumor:weight ratio and MVD in Rg3 group and Rg3-N group declined significantly (P<0.01). Besides, there was no significant difference between Rg3 group and Rg3-N group. At the same time, the level of VEGF mRNA, the protein expression of MMP-9, HIF-1α, VEGF in Rg3 group and Rg3-N group decreased compared with NS group. Furthermore, the level of each index above-mentioned in Rg3-N group was lower than that in Rg3 group. The expression of Ki-67 in PEG group, Rg3 group and Rg3-N group showed no significant difference compared with NS group. CONCLUSION Rg3 and PEG-PLGA-Rg3 nanoparticle may suppress the expression of VEGF, MMP-9 and HIF-1α in Lewis lung cancer mice, thereby indirectly contributing to their antitumor effects and alleviating the mice's general status. In addition, PEG-PLGA nanoparticles embedding can promote Rg3 antitumor effect in vivo.

Abstract
The Brownian motion of molecules at thermal equilibrium usually has a finite correlation time and will eventually be randomized after a long delay time, so that their displacement follows the Gaussian statistics. This is true even when the molecules have experienced a complex environment with a finite correlation time. Here, we report that the lateral motion of the acetylcholine receptors on live muscle cell membranes does not follow the Gaussian statistics for normal Brownian diffusion. From a careful analysis of a large volume of the protein trajectories obtained over a wide range of sampling rates and long durations, we find that the normalized histogram of the protein displacements shows an exponential tail, which is robust and universal for cells under different conditions. The experiment indicates that the observed non-Gaussian statistics and dynamic heterogeneity are inherently linked to the slow-active remodelling of the underlying cortical actin network.

Abstract
In this study we investigated whether mycophenolate mofetil (MMF), a new immunosuppressant, and its metabolite mycophenolic acid (MPA) influence the activity of liver resident natural killer (NK) cells, resulting in increased susceptibility to hepatitis B virus (HBV) infection. We isolated the hepatic NK cells of C57BL/6 and C57BL/6JTgN (A1b1HBV) 44Bri) transgenic mice administered MMF in the presence or absence of interleukin (IL)-15, or incubated isolated hepatic NK cells in the presence or absence of MPA and used RT-PCR, immunolabeling to assess the expression of NK receptors Ly49A, NKG2A and NKG2D, and cytokine ELISA and [(3)H]-TdR-release assay to assess the activation and cytotoxic capacity of NK cells. After treatment of MMF in the presence or absence of IL-15, HBsAg titer was also measured in C57BL/6JTgN (A1b1HBV) 44Bri) transgenic mice. After both MPA and MMF treatments, NK cytotoxicity was reduced, NKG2D and Ly49A expression was down-regulated, but NKG2A was up-regulated. Down-regulation of NKG2D could be ameliorated by IL-15, and in HBV-transgenic mice, MMF treatment impaired NK cell activity, but did not influence virus replication, whereas IL-15 treatment depressed HBsAg titer. MPA and MMF mediate down-regulation of NKG2D in vitro and vivo, restricting the cytotoxic capacity of NK cells. Regulation of NKG2D may be important in the effect of immunosuppressant on NK cell activity and involved in HBV infection.

Abstract
Spermatogonial stem cells (SSCs) are unique male germline stem cells that support spermatogenesis and male fertility. Long non-coding RNAs (lncRNA) have been identified as key regulators of stem cell fate; however, their role in SSCs has not been explored. Here, we report that a novel spermatogonia-specific lncRNA (lncRNA033862) is essential for the survival of murine SSCs. LncRNA033862 is expressed in early spermatogonia including SSC and was among 805 lncRNAs identified by global expression profiling as responsive to glial cell-derived neurotrophic factor (GDNF), a growth factor required for SSC self-renewal and survival. LncRNA033862 is an antisense transcript of the GDNF receptor alpha1 (Gfra1) that lacks protein coding potential and regulates Gfra1 expression levels by interacting with Gfra1 chromatin. Importantly, lncRNA033862 knockdown severely impairs SSC survival and their capacity to repopulate recipient testes in a transplantation assay. Collectively, our data provide the first evidence that long non-coding RNAs (lncRNAs) regulate SSC fate.

Abstract
OBJECTIVE To study the distribution of HPV16 E6 gene mutations and p53 codon72 polymorphism among women with HPV16+ cervical precancerous lesions and explore their relationship with the risk of cervical intraepithelial neoplasia (CIN) 2, 3. Materials and Meth- ods: This study analyzed a total of 112 cases of exfoliated HPV16+ cervical cell specimens which were divided into group I (normal and CIN1, 55 cases) and group2 (CIN2, 3, 57 cases). Among the 112 specimens, 85 cases were successfully amplified for HPV E6 gene by PCR and the PCR products were sequenced directly. P53 codon72 region was also amplified from the 112 specimens and the PCR products were sequenced directly and compared with the standard sequence. RESULTS Among the 85 amplified HPV sequences, point mutations such as T178G, T350G, G132A, A442C, T310G, G94T, C551A, etc. were found, among which, T178G showed the highest rate (51.76%). The rate of HPV16 E6 mutation T178G in CIN2, 3 group was significantly higher than that in normal and CINI group, i.e., in the 112 amplified p53 codon72 sequences, the distribution of Pro/Pro genotype in normal, and CIN1 group was significantly different from that in CIN2, 3 groups, and the disease risk of Pro/Pro genotype was much higher than that of Arg/Arg and Arg/Pro genotypes. CONCLUSION HPV16 E6 T178G mutation increases the disease risk of CIN2, 3. Meanwhile, compared with Arg/Arg and Arg/Pro genotypes, p53 codon72 Pro/Pro genotype more associated with the disease risk of CIN2, 3.

Abstract
We retrospectively analyzed the safety and efficacy of a myeloablative conditioning regimen with fludarabine (FLU) in unrelated cord blood transplantation (UCBT) of 30 pediatric patients with hematologic malignancies. The conditioning regimen consisted of FLU, busulfan (BU) and cyclophosphamide (CY). All of the patients received Cyclosporine (CSA) and mycophenolate mofetil (MMF) as graft versus host disease (GVHD) prophylaxis. We achieved high engraftment rates (96.7%) and rapid hematopoietic reconstitution. Acute GVHD occurred in 12 cases of the 29 engraftment patients (41.4%), and 6 cases (20.7%) were of grade III-IV. Chronic GVHD only occurred in 1 of 28 evaluable patients (3.6%). Twenty-three patients (76.7%) became infected, and 3 cases (10.0%) died of severe infections. Cytomegalovirus (CMV) reactivation occurred in 70.0% of the patients, but no CMV diseases were observed, nor did any patients die of CMV infection. The cumulative incidence of relapse (6.7%) was significantly reduced, and none of the acute lymphoblastic leukemia (ALL) patients relapsed. The 3-year overall survival (OS) and event-free survival (EFS) rates were 73.3% and 70.0%, respectively. The 3-year OS and EFS of the ALL patients was 75.0%. This conditioning regimen demonstrates good results and security in UCBT, especially in acute lymphoblastic leukemia.

Abstract
BACKGROUND It has been reported that polymorphisms of the vitamin D receptor gene (VDR) such as ApaI or BsmI may affect the risk of vitiligo. However, the results have been inconsistent. AIM To evaluate the association between two common polymorphisms (ApaI and BsmI) in the VDR gene and the susceptibility to vitiligo. METHODS The PubMed, Cochrane Library and China National Knowledge Infrastructure (CNKI) databases were searched, and OR with 95% CI was calculated. The strength of association and vitiligo risk was assessed under five genetic models: allele, dominant, recessive, homozygous and heterozygous. RESULTS Six relevant studies were identified, including five studies that assessed the ApaI polymorphism and four the BsmI polymorphism (some overlapped). The meta-analysis results indicated that either the ApaI or the BsmI gene polymorphism may increase the risk of vitiligo in East Asian populations (aa + Aa vs. AA: OR = 1.40, 95% CI 1.01-1.96, P < 0.05; bb vs. Bb + BB: OR = 1.32, 95% CI 1.09-1.59, P < 0.01). No publication bias was detected in this meta-analysis. CONCLUSION The current meta-analysis suggests that the ApaI a allele or BsmI bb genotype are associated with the risk of vitiligo in East Asian populations. Thus, these polymorphisms could be potential biomarkers for early detection of vitiligo.

Abstract
BACKGROUND/OBJECTIVES The objective of this study was to examine the relationship between upper distribution levels of glucose values in the 75-g oral glucose tolerance test (OGTT) and recommended diagnostic criteria for gestational diabetes mellitus (GDM) and adverse pregnancy outcomes. SUBJECTS/METHODS The distribution of the OGTT 2-h values of 13,501 pregnant women, which were below the World Health Organization (WHO) threshold for overt diabetes mellitus (DM), and managed in one teaching hospital in China, was reviewed and related to maternal characteristics and pregnancy outcomes. RESULTS For the entire group, the 90th and 95th percentile values of the OGTT 2-h glucose level, respectively, were close to the diagnostic cutoff values of the WHO and International Association of Diabetes and Pregnancy Study Groups (IADPSG) criteria. For adverse maternal outcomes, glucose level above the 90th percentile value was associated with increased hypertensive disorders, whereas no difference was seen with cutoff using the 95th percentile value. For perinatal outcomes, the 90th percentile was associated with increased neonatal intensive care unit admission and hypoglycemia, whereas the 95th percentile showed in addition association with phototherapy for jaundice and 5th-minute Apgar score <7. Although no differences in the incidence of adverse pregnancy outcomes were found using the different cutoffs, the >95th percentile cutoff value would have missed out 33.3-56.7% of the cases of adverse outcomes that would otherwise have been attributed to GDM. CONCLUSIONS Further studies are warranted to clarify which diagnostic criterion is most appropriate universally to identify adverse pregnancy outcomes attributed to GDM, and which could be mitigated with treatment specific for GDM.
