深圳市福田区暗娼艾滋病KAP调查分析

目的：探讨暗娼艾滋病KAP的现状，为艾滋病预防控制中的咨询、外展及其它健康教育活动提供依据。方法：在“城中村”中随机抽取55位暗娼，由经过专门培训的调查员调查并采血检验。结果：暗娼艾滋病平均知晓率为73．88％；与艾滋病相关的高危行为，呈现低龄化、职业化的倾向；为了预防艾滋病，绝大部分暗娼愿意坚持使用安全套，但实际情况并不如人意；暗娼获得艾滋病知识及相关服务并不方便；梅毒检出率为9．09％。结论：打工者的性权利长期被忽视，使卖淫拥有很大的市场，这是暗娼们乃以存在并长久不衰的重要原因之一；暗娼艾滋病知晓率有了较大提高，可能与深圳市开展艾滋病防制工作较早、力度较大有关；安全套使用率还有待提高：艾滋病外展服务亟待开展与加强。     

吗啡预处理-后处理对大鼠离体心脏缺血再灌注损伤的影响

Objective To evaluate the effects of morphine preconditioning-postconditioning on ischemia-reperfusion (I/R) injury in isolated rat hearts. Methods Male SD rats weighing 180-200 g were killed after intraperitoneal injection of heparin 500 U/kg. The hearts were immediately removed and perfused in a Langendorff apparatus with K-H solution gassed with 95%O2-5%CO2 .HR and left ventricular systolic pressure (LVSP) were measured from a fluid-filled latex balloon in the left ventricle. Global myocardial ischemia was induced by interrupting perfusion for 45 min followed by 60 min reperfusion. Forty isolated rat hearts were randomly divided into 5 groups (n = 8 each): group 1 (I/R); group II morphine preconditioning (M1 ); group Ⅲ morphine postconditioning (M2); group IV M1 + M2; group V 5-hydroxydecanoate (5-HD) + M2. Group M1 was perfused with K-H solution containing morphine 3.0 μmol/L for 20 min 30 min before ischemia followed by 10 min normal K-H solution perfusion. Group M2 was perfused with K-H solution containing morphine 3.0 μmol/L for 10 min at the beginning of reperfusion followed by 50 min normal K-H solution perfusion. Group 5-HD + M2 was perfused with K-H solution containing morphine 3.0 μmol/L+ 5-HD 10-4 mmol/L for 10 min at the beginning of reperfusion followed by 50 min normal K-H solution perfusion. Myocardial CK-MB activity was measured and myocardial infarct size (IS/AAR) detennined (by 2,3,5-triphenyl tetrazolium staining) at the end of 60 min reperfusion. Results The preconditioning, postconditioning and combination of preconditioning and postconditioning with morphine 3.0 μmol/L perfusion for 10 min all provided cardio-protective effects in terms of IS/AAR and myocardial activation of CK-MB. Conclusion Although the combination of morphine preconditioning and postconditioning can protect the heart against I/R injury, the effects are similar to those of either of them alone, and the reason may be that either of them alone protects the heart against I/R injury via activating mitoKATP .

中药治疗荨麻疹65例临床观察

1 引言荨麻疹是皮肤、粘膜血管通透性一时性增加所致。相当于祖国医学的“(疒咅)癗”“隐疹”。其病因为:“风为百病之长,善行数变”,“肺主皮毛,主一身之表”。因此,风邪容于肌肤、皮毛、腠理之间而致。 2 临床资料 2.1 一般资料:65例患者,女性45例,男性20例,以21～30岁者最多,30～40岁者
