Objective: To analyze the status of outdoor activities on weekends among children and adolescents of different educational stages in Shanghai and their impact on myopia, so as to provide a basis for formulating more specific prevention and control protocol of myopia. Methods: From September to October 2022, a stratified cluster random sampling method was employed to select 84 schools (27 kindergartens, 21 primary schools, 15 junior high schools and 21 high schools) across Shanghai, enrolling a total of 28 654 children and adolescents aged 4 to 18 for the study. Ophthalmic examinations were conducted to ascertain the prevalence of myopia among children and adolescents. Additionally, a questionnaire survey was administered to collect data on outdoor activity duration and associated factors. Multivariate Logistic regression analysis was utilized to investigate the associated factors of outdoor activity levels on weekends. Results: The overall myopia detection rate among children and adolescents was 58.4%, with a higher rate observed in girls (59.2%) compared to boys (57.6%). The myopia detection rates for children and adolescents with an average daily outdoor activity duration of ≥2 h and <2 h on weekends were 54.6% and 68.8%, and the differences were statistically significant ( χ 2=8.12,460.89, P <0.01). Multivariable Logistic regression analysis revealed that girls ( OR =0.80), those with a myopic parent ( OR =0.68), schools from urban districts ( OR =0.72), higher education stages (primary school: OR =0.65, junior high school: OR =0.24, high school: OR =0.14) and spending≥2 h/d on homework during weekends ( OR =0.57) among children and adolescents were less likely to engage in outdoor activities for ≥2 h on weekends ( P <0.01). After incorporating gender, parental myopia status, educational stage, school location, average daily duration on weekends for spending on homework, electronic product usage and outdoor activities as dependent variables in a multivariate Logistic regression analysis, the results showed that children and adolescents with an average outdoor activity duration for ≥2 h on weekends had a lower risk of myopia ( OR =0.86, P < 0.01). Conclusions The level of outdoor activity among children and adolescents on weekends needs to be improved. Outdoor activities on weekends is an associated factor for myopia among children and adolescents. Particularly, girls, those with myopic parents, schools from urban districts, and spending long hours on homework during weekends among children and adolescents require increased attention.

Objective To explore the effect of circ_0039411 on gastric cancer cells by regulating neutrophil extracellular traps(NETs)through miR-423-5p/interleukin-8(IL-8).Methods We used quantitative real-time reverse transcription polymerase chain reaction(qRT-PCR)to detect the expression levels of circ_0039411 and miR-423-5p in gastric cancer cell lines(HGC-27,SNU-16 and AGS)and human gastric mucosa cell(GSE-1).We selected HGC-27 to establish a circ_0039411 low expression model,and set up Experimental group(transfected circ_0039411 siRNA)and Blank control group(transfected control siRNA).We selected the cell of Experimental group to establish a miR-423-5p low expression model,and set up inhibitor group(transfected miR-423-5p in-hibitor)and NC group(transfected empty).We used phorbol 12-myristate 13-acetate(PMA)to induce the formation of NETs in vitro,and established a PMA group(induced by PMA)and a control group(not induced by PMA).We used Transwell chamber to construct a co-culture model of gastric cancer cells and neutrophils.We used CCK-8 to detect the activity of gastric cancer cells,scratch and Tran-swell to detect the migration and invasion ability of gastric cancer cells,enzyme linked immunosorbent assay(ELISA)to detect the expres-sion level of IL-8,and immunofluorescence to detect the formation of NETs.Results The expression levels of circ_0039411 and IL-8 in gastric cancer cells HGC-27,SNU-16 and AGS were higher than those of human gastric mucosa cells GSE-1,and the expression level of miR-423-5p was lower than that of GSE-1,and the differences were statistically significant(P＜0.05).Compared with the Blank control group,the activity,migration and invasion ability of cells and the secretion of IL-8 in the Experimental group were de-creased,and the differences were statistically significant(P＜0.05),and the formation of NETs was reduced.Compared with NC group,the cell activity,migration and invasion ability and secreted IL-8 of inhibitor group were increased,and the differences were statistically significant(P＜0.05),and the formation of NETs was promoted.Compared with the control group,the PMA group exhibited significantly higher activity,migration ability,and invasion ability in gastric cancer cells,with statistically significant differences(P＜0.05).Conclu-sion circ_0039411 can promote the formation of NETs through the miR-423-5p/IL-8 axis,and further promote the migration and in-vasion ability of gastric cancer cells.

Anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV) induced by anti-thyroid drugs has been reported occasionally, but methimazole-induced AAV is not as frequently reported. This case report described a 54-year-old male who developed AAV and multiple organ failure after more than 20 days of methimazole treatment. After timely discontinuation of the disease-causing drug methimazole, the patient received methylprednisolone shock, cyclophosphamide immunosuppression, renal replacement therapy, and other supportive treatments, and the disease was alleviated without recurrence.
