两县暗娼商业性行为中安全套协商的现状调查

目的了解暗娼商业性行为中安全套协商的现状及影响因素,为推广安全套使用提供新的干预方向。方法采用横断面调查设计,问卷调查暗娼人口学特征、性行为特征、安全套协商特征等。采用二分类Logistic回归模型分析安全套协商相关特征的可能影响因素。结果最近1个月性行为中,91.9%的暗娼每次都要求嫖客使用安全套,4.2%感觉要求嫖客使用安全套困难,71.4%使用过“无套无性”策略与嫖客协商安全套使用,59.7%最近1个月说服过嫖客使用安全套。多因素结果显示,≥24岁(OR=3.02)、感觉要求嫖客使用安全套不困难(OR=6.89)会增加暗娼每次都要求嫖客使用安全套的可能;≥24岁(OR=1.91)、感觉要求嫖客使用安全套不困难(OR=2.94)也会增加暗娼使用“无套无性”策略的可能。与嫖客发生阴道交+口交或肛交(OR=2.44)、最近1年接受过艾滋病干预服务(OR=1.89)会增加暗娼说服嫖客使用安全套的可能;主要基于电话/网络招揽嫖客(OR=0.25)会减少暗娼说服嫖客使用安全套的可能。结论暗娼要求嫖客使用安全套的意识较高,安全套协商策略以“无套无性”为主。

Preparation, characterizationand preliminary in vivo stud-ies of inactivated SARS-CoV vaccine

A large quantity of SARS-CoV virus was pro-liferated in Vero cells, inactivated with b-propiolactone, then purified by Sepharose 4FF column chromatography to pre-pare inactivated vaccine. The vaccine was identified by Western blot, mass spectrographic analysis, ELISA and elec-tron microscopy. The vaccine with or without aluminum hydroxide adjuvant was inoculated into female BALB/c mice at different dosages. The result showed that the antibodies to SARS-CoV were induced in the mice. The antibody levels induced by the vaccine with aluminum hydroxide were higher than those without aluminum hydroxide.
