Objective:To study the mental health status of middle school students in Three-Gorges area of Chongqing in order to provide theory support for mental health education. Methods:1 014 middle school students in Three-Gorges area were tested by SCL-90. Results:The occurrent rate of mental problems with students was 19.8%,of which the first three factors were hostility,compulsiveness and interpersonal sensitivity. Girls’ overall score and mean scores of interpersonal sensitivity, depression,anxiety and phobic anxiety were significantly higher than boys’. The overall score and factor mean scores of senior high school students were significantly higher than those of junior high school students’ except hostility and phobic anxiety factors. The mean scores of interpersonal sensitivity,hostility and phobic anxiety factors were significantly higher than the counterparts in the norms of middle school students,while the mean scores of somatization and anxiety factors were significantly lower than the counterpart in the norms of middle school students. Conclusion:The mental health status of middle school students in Three-Gorges area of Chongqing is poor,and mental health education should be enhanced by all of us.

Objective:To investigate the effect of liver ultrasonography and the security to rabbits with hydrogen peroxide(H 2O 2) affused by rectum.Methods:48 rabbits were divided into 4 groups according to different H 2O 2 concentrations,and each group was divided into 4 groups according to different H 2O 2 dosages. Each rabbit was affused with H 2O 2 by rectum,then the effect of liver ultrasonography was observed,and the damages to the tissues of rabbits were pathologically checked.Results:The liver structure could be clearly developed with 1% H 2O 2 10ml affused,and the liver gray value increased with the H 2O 2 concentration increased.The time from affusion to develop was shortened and the duration of high echo was prolonged.But at same H 2O 2 concentration,the time to develop was not significantly different with the H 2O 2 dosage increased,and the high echo was decreased more slowly.The average survival time of rabbits was significantly negatively correlated to the H 2O 2 concentration(?=-0.99),while the damage degree was significantly positively correlated (?=+0.99).Conclusion:H 2O 2 affusion can induce damage to tissues and microcirculation,while produce better liver ultrasound image,so it is important to chose suitable H 2O 2 concentration and dosage,to extend its clinical application.
