RESUMO
Objective@#To study the relationship between physical health of college students and the risk of sports injuries, and to provide a reference for sports injuries prevention.@*Methods@#The convenience sampling method was used to select 1 237 college students from grade 1 to 4 majoring liberal arts, sciences, and sports (non sports students) in Shanghai. The three types of physical fitness test scores of form, function and quality were used to investigate the occurrence of sports injuries of students in the past year through self report. Logistic regression analysis, multiple linear regression and two piecewise linear regression models were used.@*Results@#The incidence of sports injuries among college students was 12.5% (155). There was a non linear relationship between physical health score and the occurrence of sports injury events. When the physical health score was less than 70, there was negatively correlated with the risk of sports injury ( OR = 0.88 , 95% CI =0.85-0.91, P <0.05). When the physical fitness score was greater than or equal to 70, there was no statistically significant difference in the risk of sports injury between different scores ( OR = 0.98 , 95% CI =0.95-1.02, P >0.05).@*Conclusion@#The physical health level of college students is negatively related with the risk of sports injury. It is recommended that college students have a physical fitness score of at least 70 points.
RESUMO
Objective To analyze the endoscopic and clinicopathologic features of early esopheal carcinoma and precancerous lesions and evaluate the necessity, efficacy and safety of ESD in the treatment. Methods From May 2013 to April 2016, 51 consecutive patients underwent high-resolution video endoscopy and biopsy, confirmed diagnosis of early esophageal squamous cell carcinoma or intraepithelial neoplasia were included. There were capillary loops (IPCL), iodine-staining, preoperative and postoperative pathology, and complications to analyze. Results 51 patients had total 58 lesions, Type A, Type B1, Type B2 of IPCL classification were diagnosed in 8 (13.79%), 44 (75.86%), 6 (10.34%). Low-grade intraepithelial neoplasia (LGIN), high-grade intraepithelial neoplasia, early esophageal carcinoma of preoperative biopsy were diagnosed in 11 (18.97%), 42 (72.41%), 5 (8.62%), low-grade intraepithelial neoplasia (LGIN), high-grade intraepithelial neoplasia, early esophageal carcinoma of postoperative pathology results were diagnosed in 10 (17.54%), 27 (46.55%), 21 (36.21%), concordance rate of pathological results were 60.34%. Complications included micro-perforations (0.00%), strictures (8.62%) and delayed hemorrhage (3.51%), respectively. Conclusion After endoscopic submucosal dissection, detection rate of early esophageal cancer increased significantly, preoperative biopsy had guidance significance in diagnosis and treatment, ESD treatment can reduce the missed diagnosis of early esophageal carcinoma.
