ABSTRACT
Objective@#To investigate the situation of social sports activities and the relationship with depression among junior middle school students, to provide evidence for depression intervention.@*Methods@#A total of 3 623 students from eight middle schools in Chengdu were recruited and surveyed by self-made questionnaire during Sept. to Dec. 2019 Z test, Chi-Square test and Logistic regression analysis were applied to explore influence factors.@*Results@#The prevalence of depression symptoms was 45.60%. 57.34% of the students liked social sports activities, 65.87% of them participated in social sports activities during the past week, 42.25% took less than 30 minutes on exercise while 22.24% took over 45 minutes. Among the students, 20.16% of them had no special feeling after social sports activities, while 31.88% felt sweat. Uni-variate analysis indicated that compared with boys, girls participated more frequently and got stronger feeling than boys (χ2/Z=6.28，-2.67，P<0.05). Regression results indicated that for boys, high grade,low education degree of mother, low household socioeconomic status, not the only-child ,exercise alone would significantly increase the risk of depression, while liking social sports activities was protective factor (OR=1.26，1.91，1.52，2.56，1.58，1.71，0.77，P<0.05). For girls, high grade,low education degree of father, without one-child would significantly increase the risk of depression, while like social sports activities was protective factor(OR=1.29，1.74，1.37，1.47，0.66，P<0.05).@*Conclusion@#Social sports activities could reduce depression symptoms, which can be considered as first choice as after-class activity among junior middle school students.
ABSTRACT

ABSTRACT
After blast injury, the morphologie and ultrastructural differentiation of the rabbit corneal endothelium in primary culture was evaluated and compared with the Na/K ATPase activity that occoured during wounding and healing. Morphologie and ultrastructural changes were investigated by light microscopy (LM), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The endothelial injury and recovery after blast can be described as a three—stage process. Stage one was characterized by a desquamation, degeneration and necrosis of endothelial cells and a low activity of Na/K ATPase; In stage two, some surviving endothelial cells appeared to migrate and divide and the activity of Na/K ATPase began to increase. In stage three, surviving endothelial cells displayed a flattened configuration consisting of polygons and a high ATPase activity.
