ObjectiveTo assess the efficacy and safety of endoscopic treatment for foreign body impaction in the esophagus.MethodsDemographic and endoscopic data of a total of 78 patients with esophagus foreign body impactions were retrospectively studied,which included foreign body types,number,location and duration of impaction,associated esophageal diseases,endoscopic procedures and complications.The factors which influenced the complications and procedure time were also statistically analyzed.Results Impaction (80.7％ ) and perforation (66.7％ ) most frequently occurred in the upper esophagus.Duration of foreign body impaction exceeded 24 hours in 11 patients ( 14.1％ ),which was less than 24 hours in 67 others (85.9％).All of the foreign bodies were successfully removed (2 cases of perforation were transferred to other department for further treatment),and there was no mortality related to endoscopic management occurred.The common complications included mucosal injury,bleeding,and perforation.Shape of the foreign bodies,duration of impaction and status of perforation were the main influential factors on procedure time and complications (P ＜ 0.05).ConclusionThe endoscopic management for esophageal foreign body impaction is safe and effective. It is the first choice for those whose esophagus is perforated with foreign bodies for less than 24 hours and with no abscesses out of esophageal tract.

Objective:To investigate the association between estradiol on the day of human chorionic gonadotropin (HCG) administration and birth outcomes among singleton live births following fresh embryo transfers.Methods:Based on the clinical reproduction medicine management system of the First Affiliated Hospital of Nanjing Medical University, this retrospective cohort study collected data of fresh embryo transfer cycles during January 2013 and December 2016, including pregnant women’s age, body mass index (BMI), type and cause of infertility, assisted reproductive therapy indicators (fertilization mode, ovulation stimulation protocol, estradiol levels on HCG administration day), adverse birth outcomes[small for gestational age (SGA), premature and low birth weight (LBW)], etc.. A total of 2 060 women with singleton pregnancy (2 061 fresh embryo transfer cycles) were enrolled. Multivariate logistic regression was used to analyze the association between estradiol on HCG administration day and singletons’ adverse birth outcomes.Results:The age and BMI of the 2 060 pregnant women were (29.63±3.92) years old and (22.29±2.86) kg/m 2. Incidences of SGA, premature and LBW were 9.8% (201/2 061), 6.9% (143/2 061) and 3.5% (73/2 061), respectively. After adjusting for confounders, the risk of LBW in 4 000-4 499 pg/ml group was significantly elevated when compared to estradiol<1 500 pg/ml group [ OR (95% CI): 4.42 (1.13-17.24)]. A protective effect of premature was observed in estradiol≥4 500 pg/ml group [ OR (95% CI): 0.50 (0.25-0.97)]. Conclusion:The high level of estradiol on HCG administration day might be a risk factor for LBW, but a protective factor for premature.

Objective To investigate the research status and the research hotspots on male nurses at home and abroad in last decade,so as to provide references for further research in male nurses.Methods Literature between 2013 and 2024 on male nurses were retrieved from the Web of Science(WOS)and CNKI.CiteSpace 6.2.6 R7 software was used to analyse the volume of publication,keyword co-occurrence,keyword clustering and emergence.Results A total of 736 articles were included in the study.From 2013 to 2023,the number of published papers of male nurses in CNKI and WOS showed an increasing trend.The research was primarily affiliated with 263 institutions across 62 countries.The country with the highest volume of publication is China,followed by the United States,although there was a need to enhance collaboration with other nations.The institution with the most publications is the Hong Kong Polytechnic University.A comprehensive analysis of keyword co-occurrence,clustering,and emerging trends revealed that the research hotspots in the field of male nursing in CNKI mainly includes the advantages of male nurses,psychological capital,humanistic care,development,needs,professional identification.Whereas WOS focuses on the topics such as gender bias against male nurses,mental health,workplace violence,ambivalent sexism,motivational barriers,individual differences,societal prejudice and knowledge and attitucle.Both domestic and international research on male nurses primarily consist of cross-sectional surveys and qualitative studies,with fewer intervention studies.Currently,the researches regarding male nursing focus on the qualitative study of mental health of male nurses.Conclusion Focusing on the mental health and professional status of male nurses,domestic scholars need to increase the formulation and implementation of interventions in this field in order to address the practical issues faced by male nurses,therefore to promote the comprehensive development of the nursing profession,enhance the overall quality and service quality of the nursing team,and provide patients with higher quality in nursing services.

Birth cohort is an important observational study which can continuously and dynamically collect the exposure changes and health outcomes from gametophyte development to adolescence and even old age. However, because of its complex design and difficult implementation, how to construct birth cohort with high quality and high efficiency is the main difficulty faced by epidemiologists at home and abroad. In 2016, China National Birth Cohort was officially launched. The network and information technology were used to explore, and a set of "cloud-based information platform" was established to support this queue construction, containing 16 units in China. After four years of development, the platform has formed a complete set of programs about the construction of cohort information platform, which including recruitment and follow-up management of participants, real-time data interaction, queue quality control, multi-level authority management and function division. The relevant design framework and functional elements provide the references to the future information construction of large-scale birth cohort and even population-based research in China.
