Objective To evaluate effect of intervention on acquired immune deficiency syndrome(AIDS) high-risk sexual behavior of males who have sex with males(MSM)population in Jilin,and to provide a basis for establishing apropriate intervention strategy for this population.Methods A cross-sectional survey was carried out on the MSM population of young students with the method of classification.Comprehensive intervention strategy included health education via new media,behavioral intervention,voluntary conseling and testing,peer education,condom promotion and standardized services for clinic of sexually transmitted diseases(STDs)and other comprehensive interventions.Before and after intervention,300 MSM were enrolled,and their demographic characteristics,knowledge of AIDS prevention and control,high risk behaviors and intervention measures were investigated and analyzed.Results Before and after the intervention,the awareness rate of AIDS related knowledge was 67.67％ and 94.33％,respectively,the condom usage rate was 23.57％ and 11.79％ in the most recent and the last 6 months before the intervention,and it was 76.21％ and 62.10 ％ after the intervention,respectively.The proportion for those who used condom every time in heterosexual sex behavior was increased from 23.53％ (before intervention) to 69.60 ％ (after intervention),and the condom usage rate in the last 6 months was increased from 15.44％ to 66.40％.Proportion of the MSM who had STDs related symptoms was decreased from 21.33％ to 7.67％ after the intervention.Conclusion After the comprehensive intervention,the awareness rate of AIDS related knowledge among MSM in Jilin is significantly increased,the incidence of highrisk sexual behavior is decreased and the condom usage rate is improved.Intervention by use of new media is low-cost,easy to operate,and can be used as a good supplementary strategy for traditional behavioral intervention.

Objective To investigate into the indications and related anatomic foundation of transjugular intrahepatic portosystemic shunt(TIPS) creation by direct transcaval approach in patients with portal hypertension cirrhosis suffering unusual anatomy between the hepatic veins and portal bifurcation; and to evaluate the security, feasibility and clinical significance. Methods Direct transcaval approach TIPS were performed in 65 patients including active variceal bleeding (n=52), intractable ascites (n=12), and as a bridge to liver transplantation (n=1). Results Technical and functional success were achieved in all patients. The success rate was 100% without related complications including the technique and primary patency rate is obvious higher than classical TIPS. Conclusion In patients with unusual anatomy between the hepatic veins and portal bifurcation, and inaccessible or inadequate hepatic veins, transcaval TIPS creation is secure and feasible. The results suggest that the direct transcaval approach offering favorable primary patency because the shunt has a straight line in construction.

Objective: To evaluated the granules stabilities in four conditions by taking the change of Baricalin content and granules surface color as stability test markers. Methods: The content of baicalin was determined by dual wave length iso absortion method and the granules surface color was determined by the diffuse reflectrance spectroscopy. ① The granules were tested in a simulated summer environment (30 ?C , RH92.5%, 1month) and in a high intensity light condition (3000LX, 10dyas). ② The influence of humidity on the stability of the granules was investigated. ③ The expiry date of the granules was predicted by the mutivariate linear regression analysis and compared with the result of the classical constant temperature method. ④ The influences of temperature and humidity on the granules stability were etudied by orthogonal test. Results: ① There was hardly any change in baicalin content of samples in a simulated summer environment and in a high intensity light condition. ② The results showed that the decrease of baicalin content and charge of granules color were obvious when the relative humidity of environment was high and the granules color was more easily influenced by the humidity. ③ The expiry date was about 2.87 years. ④ The results indicated that both temperature and humidity had effects on the change of baicalin content. Conclusion: We tried to estimate the stability of the granules by two indexes. The results showed that Qingrejedu granules was stable in different conditions. It satisfied the stability requirements of solid dosage form.
