[Objective] The aim was to explore the effects of seven kinds of Chinese herbal medicine on Escherichia coil and Staphylococcus aureus in terms of unilater- al bacteriostatic effect, such as root and leaf of Ophiopogon japonicus, honeycomb, Panax pseudoginseng, and Allium macrostemon. [Method] Herbal active ingredients were extracted by water boiling method and a bacteriostatic experiment was per- formed by oxford cup diffusion method, to select Chinese herbs with antibacterial effects. MIC values of seven kinds of Chinese herbal medicine were determined by in vitro half-fold dilution method. [Results] Root and leaf of Ophiopogon japonicus, honeycomb, Panax pseudoginseng, Allium macrostemon, Juncus effusus and Xanthi- um sibiricum had bacteriostatic effects on Escherichia coil and Staphylococcus au- reus in varying degrees. Xanthium and leaf of Ophiopogon japonicus performed bet- ter on Escherichia coil, with MIC values at 7.81 and 15.63 mg/ml, respectively. Panax pseudoginseng and Xanthium performed better on Staphylococcus aureus with MIC values at 15.63 and 31.25 mg/ml. And the drug＇s effect was positively correlated with the concentration. [Conclusion] Xanthium sibiricum is the best bacte- riostatic effect, followed by leaf of Ophiopogon japonicus, and Juncus effusus per- forms the poorest. Panax pseudoginseng showed the best bacteriostatic effect, fol- lowed by Xanthium sibiricum and Juncus effusus performs the poorest. These pro- vide references for clinic safety.
目的：分析农村中老年留守妇女获得性免疫缺陷综合征（AIDS）健康教育及行为干预效果。方法整群抽样法抽取河南省三个大县40个自然村，运用自设问卷调查表对1200名46～60岁的目标人群进行1年的干预，并与基线调查结果进行比较分析。结果近90％农村中老年留守妇女的文化程度在初中及以下水平。通过1年的AIDS健康教育及行为干预，农村中老年留守妇女AIDS平均知晓率由干预前的31.9％上升到76.1％（P＜0.01）；各单项AIDS非传染认知显著性提高：如与 AIDS 感染者共同进餐、蚊虫叮咬和共用泳池能否传染，分别由干预前的26.8％、28.8％和26.3％提高到干预后的73.9％、70.1％和75.6％（P＜0.01）；夫妻团聚期间安全套使用率由干预前的1.2％提高到干预后的18.5％，但仍有73.8％的人从不使用。结论健康教育及行为干预对提高农村中老年留守妇女AIDS认知水平行之有效。
