RESUMO

Objective@#To investigate the current status of HIV-related stigma among college students in Guilin,and to explore the impact of perspective-taking and empathy on HIV-related stigma among college students.@*Methods@#The stratified cluster sampling method was used to select college students from 4 universities in Guilin city. Stratified randomization was used to assign all subjects into a control group (410) and an experimental group (396) for randomized controlled trials,and the HIV-related Stigma Questionnaire and the Basic Empathy Scale were used before and after the intervention.@*Results@#Before the intervention of perspective-taking,there were no statistically significant differences between two groups in subscale scores and total scores of HIV-related stigma (t=0.80,0.35,-0.62,-0.10,P>0.05); However, signiticant differences in subscale scores and total score in HIV-related stigma were found after intervention (t=3.53,2.21,2.30,3.98,P<0.05). There was no statistically singnificant in the scores of all dimensions of empathy level and the total score before the intervention (t=0.10,-0.27,-0.08,P>0.05), dimensional score and total score in empathy were statistically significant after intervention (t=-2.15,-3.06,P<0.05). Empathy played an intermediary role of 14.08% between opinion selection and HIV stigma.@*Conclusion@#HIV-related stigma exists among college students in Guilin,and perspective-taking intervention effectively reduces its AIDS stigma. Empathy plays an intermediary role between them.

RESUMO

Kinematical alignment during total knee arthroplasty is an emerging process, and draws more and more attentions from scholars. Knee joint is close to normal joint after TKA through kinematical alighment, which has good clinical results and functional scores, and not increase failure probility. Thus, it may increase joint stress of patella-femur joint, lead to patellar maltracking and increase abrasion. The paper summarized defination and basical principle, operative method, clinical outcomes and deficiency of kinematical alignment during total knee arthroplasty, in order to choose a better way for kinematical alignment during total knee arthroplasty.

RESUMO

Enramycin is a polypeptide antibiotic and new, safe animal feed additive. A new purification process was developed, based on pre-purification by macroporous resin and refining by reversed phase chromatography. AB-8 macroporous resin was used for the pre-purification process of enramycin, with an elution buffer of 0.012 mol/L aqueous HCl solution-methanol (50: 50, V/V). Then, enramycin a and enramycin b were separated effectively by C18 reversed phase chromatography, with a elution buffer of 0.05 mol/L aqueous KH2PO4 solution-acetonitrile (70: 30, V/V, pH 4.5). The purities of enramycin a and enramycin b were up to 98.5% and 98.0%, respectively. The yield reached 29.2%. This study would provide a useful reference for the preparation of enramycin a and enramycin b with a high purity.
