Generative artificial intelligence (GAI) represents a prominent research focus in medicine, with medical education being a key application area. GAI demonstrates potential to enhance residency training efficacy through personalized instruction, automated assessment item generation, question bank updating, and intelligent scoring systems. However, current limitations exist regarding output accuracy and content consistency. To address these constraints, strategic measures are required: continuous GAI model refinement, development of standardized usage guidelines, enhanced data quality control, and implementation of human verification protocols for generated content. Concurrently, residents should proactively acquire GAI utilization skills to strengthen the practical application of theoretical knowledge. With these advancements, GAI is anticipated to evolve into a valuable asset for improving the efficiency and quality of residency training programs.

Objective: To investigate the knowledge, attitude and practice of infectious disease prevention and control among primary and middle school students in Gongshu District, Hangzhou City, so as to provide the evidence for implementing health education on infectious disease prevention and control in schools. Methods: Students from 12 primary and middle schools in Gongshu District were selected using a random cluster sampling method. Basic information, knowledge, attitude and practice of infectious disease middle and control were collected through questionnaire surveys. Influencing factors of practice of primary and middle school students' infectious disease prevention and control were analyzed using multivariable logistic regression model. Results: A total of 3 439 primary and middle school students were surveyed, including 1 717 boys (49.93%) and 1 722 girls (50.07%). There were 1 237 primary school students (35.97%), 1 092 junior high school students (31.75%), and 1 110 senior high school students (32.28%). The awareness of infectious disease prevention and control knowledge, the percentage of attitude towards infectious disease prevention and control, and the percentage of practice towards infectious disease prevention and control were 73.22%, 96.83%, and 60.19%, respectively. Multivariable logistic regression analysis revealed that girls (OR=1.460, 95%CI: 1.265-1.685), those who had received health education on infectious disease prevention (OR=2.088, 95%CI: 1.656-2.632), those with adequate knowledge (OR=2.129, 95%CI: 1.816-2.496), and those with positive attitude (OR=4.320, 95%CI: 2.683-6.957) were more likely to form practice for the prevention and control of infectious disease. Conversely, senior high school students (OR=0.667, 95%CI: 0.561-0.794) and those with poor self-rated health status (OR=0.678, 95%CI: 0.495-0.930) were less likely to form practice for the prevention and control of infectious disease. Conclusions The attitude towards infectious disease prevention and control among primary and middle school students in Gongshu District is relatively high, but their awareness and practice are low. It is recommended to strengthen health education on infectious disease prevention and control knowledge in a targeted manner to promote the formation of prevention and control practice among senior high school students and primary and middle school students who self-assess their health status as poor.

Objective:To investigate the application and effectiveness of the scaffolding teaching method in improving the teaching effect of septic shock and cultivating learning interest among medical students.Methods:A total of 52 medical students participating in intensive care internship were randomly divided into traditional teaching group and scaffolding teaching group,with 26 students in each group.
