Objective:To explore the effectiveness of interprofessional cooperative simulation in teaching emergency care for shock patients among intensive care unit (ICU) undergraduate nursing students.Methods:An interprofessional cooperative simulation-based teaching faculty team was established for ICU undergraduate nursing students, and a shock case library was developed. Using convenience sampling, 32 ICU undergraduate nursing students in 2022 were selected as the control group and received conventional simulation-based teaching, with students rotating through roles as nurses, standardized patients, doctors, and family members. In the experimental group, 34 ICU undergraduate nursing students in 2023 and 24 ICU clinical medicine interns were recruited to act as doctors for interprofessional cooperative simulation-based teaching. Each group was divided into subgroups, with each subgroup consisting of 4-5 nursing students. One group completed simulation-based training per month for a total of 8 sessions, with each session lasting 3 hours. The teaching adopted the on-site "tidal ward" in situ simulation, and the scenarios included patient history collection and health assessment, shock emergency care, nursing evaluation, and health education. The differences between the two groups of nursing students were compared in terms of ICU exit theoretical assessment score, objective structured clinical examination skill assessment score, and satisfaction with simulation-based teaching. SPSS 22.0 was used for independent samples t test and Mann-Whitney U test. Results:The experimental group achieved significantly higher scores in theoretical assessment (84.65±8.06), total score of satisfaction with simulation-based teaching (101.00±5.13), and clinical learning and multiprofessional team dimensions (47.32±3.35) compared to the control group ( P<0.001). The experimental group achieved higher scores in objective structured clinical examination skill assessment (81.40±7.22), guiding feedback and reflection (37.50±3.04), and judgmental thinking and clinical reasoning (16.00±2.03) compared to the control group, though the differences were not significant ( P=0.977, 0.668, and 0.636). Conclusions:Interprofessional cooperative simulation enhances the shock patient emergency care abilities and satisfaction with simulation-based teaching for undergraduate nursing students.

At present, robotic surgery system, as a cutting-edge technique in minimally invasive surgery, has become a crucial component in the training programs for outstanding surgeons. Given the relatively late start of this technique and immature faculty resources, there is an urgent need to optimize and improve the teaching philosophies and methodologies for robotic skill training in China, and Sino-foreign cooperation has emerged as a significant pathway to promote this reform. Taking the "International Robotic Surgery Training Center (IRSTC)" jointly established by The First Affiliated Hospital of Sun Yat-sen University and University of California as an example, this article provides a comprehensive analysis of collaboration background, construction of the training system, curriculum design, cooperation channels, and localization practices, in order to provide a reference and valuable experiences for Sino-foreign cooperation in clinical skill training.

With the increasing severity of bacterial antibiotic resistance， finding new ways to overcome this global challenge has become an urgent task. Chinese medicine， with abundant resources， offers potential for discovering diverse bioactive ingredients to enhance antibiotic efficacy and alleviate the crisis of bacterial antibiotic resistance. This review summarizes bacterial resistance mechanisms， prevention strategies， and the roles and mechanisms of Chinese medicine and its active ingredients in enhancing the efficacy of existing antibiotics. Two major resistance mechanisms—bacterial obstruction of antibiotic uptake and weakening of intracellular antibiotic activity—are introduced， with corresponding prevention and control strategies outlined. Based on the regulatory effects of active ingredients from Chinese medicine on bacteria， their mechanisms for enhancing antibiotic efficacy are categorized into two types， including improving the bacterial uptake of antibiotics and reducing the bacterial resistance to antibiotics. The former mainly enhances extracellular antibiotic uptake by regulating membrane permeability， biofilm formation， and metabolic pathways. The latter weakens intracellular antibiotic resistance by inhibiting efflux pumps and bacterial resistance targets. Furthermore， compound formulas of Chinese medicine， characterized by multi-component， multi-target， and multi-pathway interventions， exert similar antimicrobial effects and mechanisms with active ingredients， offering rich resources for developing antibiotic-enhancing applications. Finally， the review highlights the challenges such as insufficient structural research on active ingredients and potential druggability issues in their application for antibiotic enhancement. This will provide insights for advancing the research on Chinese active ingredients in antibiotic therapy and offers novel strategies to combat bacterial antibiotic resistance.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To evaluate the efficacy of angiogenesis inhibitors and poly ADP-ribose polymerase (PARP) inhibitors in the treatment of recurrent ovarian cancer using a mesh meta-system.Methods:Subject terms were used to search Pubmed, Embase, the Cochrane Library and web of science databases to collect randomized controlled trials related to angiogenesis inhibitors and PARP inhibitors in the treatment of recurrent ovarian cancer. The search time was established until January 1, 2024. Outcome measures included progression-free survival (PFS) and overall survival (OS). Bias risk assessment was performed using Revman 5.4 software and mesh meta-analysis was performed using gemtc package in R 4.3.1 software.Results:34 randomized controlled trials were included in the PFS and 26 in the OS. Olaparib ( HR=0.63, 95% CI: 0.40-0.99), rucaparib ( HR=0.48, 95% CI: 0.24-0.99), niraparib ( HR=0.49, 95% CI: 0.26-0.93), niraparib+ bevacizumab ( HR=0.17, 95% CI: 0.05-0.61), chemotherapy+ bevacizumab+ maintenance bevacizumab ( HR=0.54, 95% CI: 0.3-0.97) and chemotherapy+ bevacizumab ( HR=0.50, 95% CI: 0.31-0.81) had longer PFS than conventional platinum-based chemotherapy/chemotherapy+ placebo. Niraparib+ bevacizumab had the longest PFS of all pharmacological interventions. Chemotherapy plus bevacizumab ( HR=0.72, 95% CI: 0.57 -0.88) had a longer OS than conventional platinum-based chemotherapy/chemotherapy plus placebo. Conclusions:There is limited evidence that angiogenesis inhibitors alone (bevacizumab) or PARP inhibitors alone (niraparib, olaparib, and rucaparib) can improve PFS or OS in recurrent ovarian cancer, and that the combination of angiogenesis inhibitors and PARP inhibitors may be more beneficial in prolonging PFS or OS in recurrent ovarian cancer.
