The prevalence of hyperuricemia and gout is continuously increasing on a global scale,leading to increased social burden through complications such as chronic kidney disease,cardiovascular diseases,and joint disorders.Several studies have reported gender differences in the onset of gout,but the relationship between sex hormones as biologic markers and hyperurice-mia or gout has just gained attention in recent years,with ongoing debates on its authenticity and mechanisms.This article com-prehensively elaborates on the research progress in the impact of estrogen,androgen,progesterone,and sex hormone-binding globulin(SHBG)on hyperuricemia and gout,as well as underlying mechanisms.It will provide a basis for further understanding of uric acid metabolism and early prevention and treatment of gout.

Objective:To construct a training system of the professional postgraduate degree of general practice using the Delphi method.Methods:On the basis of consulting relevant policies and literature, and drawing lessons from foreign general practice training systems, the index system of training professional postgraduate medical students of general practice was preliminarily developed. After two rounds of Delphi expert consultation, using the threshold method to select evaluation indexes, the training system was finally established. Excel 2010 and SPSS 19.0 were used to make data entry and statistical analysis.Results:The active coefficients of experts in the two rounds of Delphi consultation were 75.0% (12/16) and 91.7% (11/12) respectively, both the two rounds of the degree of specialist authority were 0.87, and the final coordination coefficient of the specialists' opinion was 0.452. The index system was composed of 5 first-level indexes including training objectives, theoretical curriculum setting, clinical practice setting, teaching staff and graduation requirements and 31 second-level indexes.Conclusion:The experts have great initiative and authority on research subjects. The opinions of all experts tend to be uniform after two rounds of consultation, and the results are reliable. A relatively complete and credible training index system of professional postgraduate degree of general medicine has been built.
