OBJECTIVE To compare the efficacy and safety of vedolizumab （VDZ） versus infliximab （IFX） in biologic-naive（Bio-naive） patients with moderate-to-severe active ulcerative colitis （UC）， and to analyze the factors influencing efficacy. METHODS Clinical data were retrospectively collected from Bio-naive patients with moderate-to-severe active UC who received treatment in the Department of Gastroenterology at Shanxi Provincial People’s Hospital from June 2023 to June 2024. Based on the type of biologic agent administered， the patients were divided into the IFX group （41 cases） and the VDZ group （30 cases）. Patients in the two groups received IFX （5 mg/kg） or VDZ （300 mg） for induction and maintenance of remission therapy. The two groups were compared regarding modified Mayo score， serological indicators （hemoglobin， albumin， platelet count， erythrocyte sedimentation rate， C-reactive protein）， combined medication， efficacy-related indexes （clinical response rate/remission rate， and endoscopic response rate/remission rate）， and the occurrence of adverse drug reactions （ADR）. Based on Logistic regression model， univariate and multivariate analyses were conducted to identify potential factors influencing clinical remission at week 14 and endoscopic remission at week 38. RESULTS There were no statistically significant differences in clinical response rate/remission rate， or endoscopic response rate/remission rate between the two groups at weeks 14 and 38 （ P ＞0.05）. However， at week 14 of treatment， the proportion of patients using concomitant corticosteroids in VDZ group was 26.67%， significantly higher than the 7.50% in IFX group （ P ＜0.05）. There was no statistical significance in the overall incidence of ADR between the two groups （ P ＞0.05）； all ADRs in the IFX group were grade 3 and led to treatment discontinuation （6 cases）， whereas ADR in the VDZ group was grade 2 and did not interrupt therapy （1 case）. Univariate and multivariate regression analyses revealed that disease type （relapsing） was significantly associated with clinical remission at week 14 of treatment， and a history of smoking was significantly associated with endoscopic remission at week 38 of treatment （the odds ratios were 0.08 for both， with 95% confidence intervals of 0.01-0.77 and 0.01-0.91 respectively， P ＜0.05）. CONCLUSIONS For Bio-naive patients with moderate-to-severe active UC， VDZ and IFX demonstrate comparable efficacy in inducing and maintaining clinical remission and promoting mucosal healing， as well as overall safety. Although IFX can achieve faster control of inflammation in the early stage of the disease， it causes more severe ADR. Disease type （relapsing） and smoking history are identified as independent negative predictors for short-term clinical remission and long-term endoscopic remission， respectively.

Since the birth of the first "test-tube baby" in Chinese mainland in 1988, assisted reproductive technology (ART) in China has matured significantly. The number of ART cycles has surpassed one million, and the number of assisted reproductive institutions and practitioners has attained a significant scale, contributing to the establishment of a fertility-friendly society. However, due to the complexity of the ART process, the diversity of personnel backgrounds, and the profound impact of any error that may occur, there is an urgent need to establish an efficient and effective safety management model for error prevention. This paper aims to outline the key processes and steps involved in the implementation of ART, explore control measures for these critical processes, and delve into error prevention strategies for gamete and embryo laboratories through the creation and utilization of a "gamete safety checklist".

Objective:To extract and evaluate the relevant evidence to improve the family discharge preparation of premature infants with bronchopulmonary dysplasia, so as to provide evidence-based basis for clinical formulation of scientific and effective discharge plans.Methods:All the evidence on the family discharge readiness of premature infants with bronchopulmonary dysplasia was collected from Chinese and English databases or websites, and the quality of various studies was evaluated. JBI′s evidence grading and recommendation level system (2014 edition) was used to extract and summarize the evidence.Results:A total of 21 articles were included, and 24 pieces of evidence were summarized, which were divided into seven themes: pre-discharge planning, environmental preparedness, parent education and training, support systems, feeding and nutrition, respiratory management, and discharge follow-up.Conclusions:For preterm infants with bronchopulmonary dysplasia, discharge readiness should be improved in terms of standardizing discharge criteria and implementing a discharge plan; improving family care preparation to ensure discharge support; strengthening health management and implementing a personalized plan; and continuing high-quality follow-up to ensure long-term health.

In recent years， the number of special clinical cases related to assisted reproductive technology （ART） for pregnancy has been on the rise annually. For example， gamete donation， assisted reproduction for couples of advanced maternal ages， and the ownership and disposition of embryos when one or both partners pass away， all involve the health of offspring and conflicts of interest in the implementation of ART. Although China’s ethical principles for ART include the protection of the offspring， the detailed rules are vague and urgently need to be supplemented and improved. In addition， the clinical application of ART lacks legislative collaborative governance. The corresponding administrative departments， practitioners， and infertile couples should work together. Starting from the perspective of focusing on the well-being of offspring born from the clinical application of ART， while conducting clinical research to address technical challenges， efforts should be made to overcome ethical dilemmas in the application of technology， comprehensively consider the well-being of offspring born from assisted reproductive treatments and help them seek the best care to promote their healthy growth.

Objective:To explore the consistency of claudin 18.2 immunohistochemistry (IHC) using 4 different clone antibodies in gastric adenocarcinoma.Methods:A total of 226 gastric adenocarcinomas diagnosed and treated at the Drum Tower Hospital Affiliated to Nanjing University Medical College between January 2022 to March 2023 were included in this study. The cohort consisted of 165 males and 61 females, with a mean age of (61.3±12.1) years. Tumor tissues from radical resection specimens were collected for tissue microarrays. IHC detection of claudin 18.2 was performed using the EnVision method, utilizing 4 clones of antibody: OTIR157B5, 43-14A, EPR19202 and D313D22. The results were interpreted based on both the intensity of staining on tumor cell membranes and the percentage of positive tumor cells relative to the total tumor cells.Results:The positive cutoff value was set as moderately to strongly linear membrane staining in ≥75% of all viable invasive tumor cells, and clone OTIR157B5 demonstrated the highest positive expression rate at 52.2% (118/226). Additionally, the clones OTIR157B5, 43-14A, and EPR19202 were consistently and strongly positive, with all agreement rates of Cohen κ exceeding 0.8. In gastric adenocarcinoma and its three Lauren subtypes, OTIR157B5 exhibited clear membranous localization.Conclusions:Clone OTIR157B5 of claudin 18.2 antibody shows the highest rate of moderately to strongly linear membrane-positive staining, accounting for ≥75% of all viable invasive tumor cells, and clones 43-14A and EPR19202 show strong consistency and high sensitivity.

OBJECTIVE To explore the levels of helper T lymphocytes(Th)in patients with hepatitis B virus(HBV)infection who were treated with entecavir and observe the impact on viral clearance.METHODS A total of 149 patients with HBV infection who were treated with entecavir in Yan'an Hospital of Kunming City from Jan.2020 to Jan.2024 were enrolled in the study,82 of whom were chronic hepatitis B(CHB),and 67 were chro-nic hepatitis B virus carriers.The enrolled patients were divided into the clearance group with 64 cases and the no clearance group with 85 cases according to the levels of serum hepatitis B surface antigen(HBsAg)at Week 72 of the treatment.The clinical data were compared between the two groups,and the changes of Th1 and Th2 levels during the treatment were analyzed.Multivariate linear regression analysis was performed for the association be-tween virological change during the treatment and immune level.The risk factors for failed clearance of viruses were analyzed by logistic regression model.RESULTS There were significant differences in the age,the levels of alanine aminotransferase(ALT)and HBV DNA between the baseline and Week 24,the levels of aspartate trans-aminase(AST)at the baseline and Week 12,the HBsAg level at Week 24,and the baseline levels of Th1,Th1/Th2 between the CHBc treatment group and the CHB treatment group(P＜0.05).There were linear correlations between the HBV DNA,HBsAg,hepatitis E antigen(HBeAg)and the Th1,Th2 and Th1/Th2,respectively(P＜0.05).Totally 64 patients were accumulatively eradicated with HBsAg on Week 72,with the eradication rate 42.95％.After the confounding factors were adjusted,multivariate analysis showed that the high levels of Th1,Th2 and Th1/Th2 were the risk factors for the failed clearance of viruses(P＜0.05).CONCLUSIONS Among the patients with HBV infection,there is difference in the immune level between the CHB patients and the CHB virus carriers.The levels of Th1,Th2 and Th1/Th2 are strongly correlated with the HBV DNA,HBsAg,HBeAg and efficiency of viral clearance during the treatment with entecavir.

Congenital orofacial cleft, the most common birth defect in the maxillofacial region, exhibits a wide range of prognosis depending on the severity of deformity and underlying etiology. Non-syndromic congenital orofacial clefts typically present with milder deformities and more favorable treatment outcomes, whereas syndromic congenital orofacial clefts often manifest with concomitant organ abnormalities, which pose greater challenges for treatment and result in poorer prognosis. This consensus provides an elaborate classification system for varying degrees of orofacial clefts along with corresponding diagnostic and therapeutic guidelines. Results serve as a crucial resource for families to navigate prenatal screening results or make informed decisions regarding treatment options while also contributing significantly to preventing serious birth defects within the development of population.
