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。

P17 Pharmacology in the integrated course ＂Basic Medical Sciences＂ in Zhejiang University School of Medicine

According to traditional teaching mode, the courses in preclinical medicine including pharmacology are separately run. This mode causes a series of disadvantages including loose connection between knowledge in different disciplines and weak ability to bridge basic preclinical knowledge and clinical practice. In order to overcome the disadvantages and promote the teaching efficiency, we constructed a new integrated course-Course of Basic Medical Sciences, which includes 6 traditional courses, anatomy, histology and embryology, physiology, pathology, pathophysiology and pharmacology. We integrated these courses based on the human organ systems and according to the principle-＂ From macro to micro, From morphological to functional, From normal to abnormal and From disease to drug therapy＂ and published the series of textbook in 2004. The contents of pharmacology are taught just after pathology and pathophysiology in every organ system. In comparison with the traditional teaching mode, teachers of pharmacology need not spend a lot of time to review preceding knowledge of anatomy and histology, physiology, pathophysiology and pathology. This is helpful in saving time and improving the teaching efficiency.

GENERAL SURGERY——Breast The effect of HO-1 activated via P38α pathway in the genesis and chemotherapy resistance of breast carcinoma

Objective To investigate the role of p38a pathway and HO-1 in the genesis and chemotherapy resistance of breast cancer. Methods The proliferation and apoptosis of human breast cancer cells were examined by MTT assay. The expression of p38a and HO-1 mRNA were examined by RT-PCR. Results The p38a mRNA level in 78 % of samples was significantly greater than that in the normal tissue and the p38a mRNA level in patients with lymph node metastasis was higher than that without lymph node metastasis （P 〈 0.01 ）. The HO-1 activated with 5 μmol/L pirarubicin increased more in MCF-7/adr cells than in MCF-7 cells, and was completely blocked by p38a inhibitor in MCF-7/ADR but only partially in the MCF-7 cell line.
