Objective:To analyze research hotspots and current trends in the field of general practitioner (GP) training in China through a visual analysis of relevant literature.Methods:Publications related to GP training were retrieved from the China National Knowledge Infrastructure (CNKI), Wanfang Database, VIP Database, China Biology Medicine (CBM) Database, and Chinese Medical Association Journal Database from database inception to December 31, 2024. VOSviewer and CiteSpace were used to perform co-occurrence analysis of authors and institutions, as well as co-occurrence, clustering, and burst detection analysis of keywords, with corresponding visual maps generated.Results:A total of 4 131 publications were included, with the highest annual output occurring in 2019 (305 publications). There were 259 core authors (each with ≥7 publications). A total of 3 093 institutions participated in related research, with leading institutions including Capital Medical University (140 publications), Zhongshan Hospital Affiliated with Fudan University (108 publications), Guangzhou Medical University (65 publications), and Shanghai Jiao Tong University (53 publications). Keyword co-occurrence analysis identified 189 keywords with frequency ≥10; high-frequency terms included "general practice","general practitioners","education" and "community health services". Keyword clustering revealed current research hotspots mainly focus on training models, educational reform, and training outcome evaluation. Timeline and burst detection analyses indicate that medical education and post-placement training have long been key research themes, while recent emerging topics are closely aligned with national policy initiatives related to GP training.Conclusion:Publications in the field of GP training in China have shown fluctuations, with a concentration of authors and institutions. Reforms in educational systems and policy responsiveness remain core research focuses.

Objective:To study the levels of individual dose of radiation workers in a steel enterprise in Baotou City from 2018 to 2022, and analyze the main factors affecting the annual dose, and provide basic data for revising relevant standards.Methods:According to the requirements of occupational external exposure personal monitoring standards (GBZ 128-2019), the personal dose monitoring of workers working in a steel enterprise in Baotou City from 2018 to 2022 was carried out, three months for a period, continuous monitoring 4 periods, and the results were analyzed.Results:A total of 1 360 workers from 10 employers within the enterprise were surveyed. The annual doses were in the range of 0.500 - 0.844 mSv, with an average annual individual dose of 0.676 mSv. Especially, the average annual individulal effective dose to workers for safety management and inspection was 0.986 mSv, hiher than 0.698 mSv to rolling workers, pump operators, and continuous casters ( Z = 56.89, P < 0.001). Additionally, female worders working with the radiation generators had a higher average annual individual effective dose of 0.821 mSv, than 0.691 mSv to the male workers who were exposed to sealed sources possibly in many cases as needed, with a statistically significant difference ( Z =-5.53, P < 0.001). Conclusions:The average annual individual effective dose to radiation workers in an iron and steel enterprise in Baotou City meets the requirements of the relevent national standard. The annual dose of women and some workers is relatively high, so the management of radiation workers should be strengthened and the radiation protection measures in the workplace should be improved.

Objective: To investigate the correlation of single nucleotide polymorphisms (SNPs) in autophage-related 5 ( ATG5 ) gene promoter with acute myocardial infarction (AMI). Methods: The SNPs of ATG5 gene promoter were detected by polymerase chain reaction (PCR) and Sanger sequencing. The typing and correlation of SNPs in 378 AMI patients and 374 healthy controls were analyzed by Chi-square test, Logistic regression analysis and haplotype analysis. Results: Two SNPs of ATG5 gene promoter, rs506027 (OR=1.4, 95% CI \[0.6-3.0\], P=0.411) and rs510432 (OR=1.6, 95% CI \[0.7-3.4\], P=0.275), were found. They didn′t increase the susceptibility of AMI, and the haplotype associated with AMI was not found in the two SNPs. Conclusion The polymorphism of ATG5 gene promoter isn′t associated with the susceptibility of AMI.
