HIV蛋白酶抑制剂研究进展

艾滋病 (acquiredimmunodeficiencysyndrome,AIDS)是由人免疫缺陷病毒(humanimmunodeficiencyvirus,HIV)感染导致人体免疫机能缺陷,而易于发生机会性感染和肿瘤的临床综合征 [1]。在过去的20多年里造成2 000多万人死亡,目前全世界艾滋病病毒感染者已达4 000万左右 [2]。自     

中研Ⅰ号、中研Ⅱ号和艾通冲剂对HIV/AIDS患者病毒载量与免疫功能作用的观察

目的:根据观察指标变化评估疗效,筛选有效复方.方法:用定量RT-PCR法检测血浆病毒栽量,用流式细胞仪检测外周血CD 4 T细胞、CD 45RAT细胞绝对值.结果:中研Ⅰ号方组病毒栽量下降5例,CD 4 T细胞计数升高3例,CD 45RAT细胞计数升高1例.中研Ⅱ号方组病毒载量下降5例,C 4T细胞计数升高4例,CD 45RAT细胞升高2例.艾通冲剂组病毒载量下降3例,CD 4T细胞计数升高4例,CD 45RAT细胞计数升高4例.同时病人的临床症状与体征有一定改善.结论:在中医基本理论指导下辨证论治,观察到三个复方均有一定疗效,其中中研Ⅱ号要优于中研Ⅰ号和艾通冲剂方.     

Measurement of self-reported HIV risk behaviors in injection drug users: Comparison of standard versus timeline follow-back administration procedures

This study compares the frequencies of retrospective self-reported HIV high-risk drug use and sexual behaviors in 127 out-of-treatment injection drug users using the HIV Risk Questionnaire (HRQ) across two administration methods: (a) a brief standard quantity–frequency approach covering the past 30 days and (b) a lengthier timeline follow-back (TLFB) procedure for improving recall. The two procedures produced similar frequencies of risk behavior across most items (80%) and good intra- and interclass correlation coefficients. The TLFB, however, resulted in higher frequencies for two risk behavior questions—sharing of any drug injection equipment and having any type of unprotected sex. The TLFB is a well-established procedure for retrospective assessment of HIV risk behavior and a good choice when precision in measuring these behaviors is a primary focus of the work. In contrast, the brief HRQ-Standard interview procedure appears to be a reasonable choice for clinical, research, and health-related surveys where the primary focus is broader than HIV risk behavior.     

人类免疫缺陷病毒首犯后天阳之本

人类免疫缺陷病毒（HIV）感染人体后,主要侵犯肺、脾二经,但首犯肺经。肺为后天阳之本,脾为后天阴之本。根据肺的生理功能和HIV病毒侵袭人体的特点,肺经的临床表现出现最早,出现的几率也最大。脾为后天阴之本,当肺脏卫外功能减退或不足的时候,病邪即可深入,引起脾经病变。同时HIV病毒对肺脾的侵犯具有较大的特异性,需要结合其他各期的病机进行综合分析,完整地认识病毒的发病特性。     

非核苷类逆转录酶抑制剂奈韦拉平

艾滋病是严重威胁人类健康的传染性疾病，它是由HIV引发，特别是HIV-1。奈韦拉平是一种新型的非核苷类逆转录酶抑制剂，该药与核苷类逆转录酶抑制剂或蛋白酶抑制剂合用可用于治疗艾滋病，单独用药可用于预防HIV感染和母婴传播。     

3种保肝药物治疗艾滋病人的药物性肝损伤的成本—效果分析

目的:评价3种保肝药物治疗艾滋病人的药物性肝损伤的成本—效果。方法:166例患者随机分为3组,分别给予还原型谷胱甘肽(A组)、复方甘草酸苷(B组)、硫普罗宁(C组),治疗28d后观察(A、B、C组)3组治疗效果,并进行成本—效果分析。结果:A组疗效显著>B、C组(P<0.05),且A组成本/效果比为3组中最低。结论:还原型谷胱甘肽(A组)为艾滋病人的药物性肝损伤的较佳治疗药物。     

流式细胞术在中医药治疗HIV/AIDS研究中的应用及不足

目的：探讨流式细胞术在中医药艾滋病毒感染者及艾滋病患者（HIV/AIDS）研究中的应用及不足。方法：查阅相关文献,根据近年来临床和基础研究中流式细胞术的应用现状,重点探讨流式细胞术在艾滋病中医药研究中存在的问题。结果：流式细胞术在中医药治疗HIV/AIDS的中医基础医学研究和临床中有着广泛的运用,但也存在着对检测的质量控制缺乏重视、使用仪器陈旧、检测项目较少等不足。结论：流式细胞术有待进一步研究和改进。     

Duties, fears and physicians

This article deals with the physician's fear of contagion using AIDS as a paradigm. It deals with this in four ways: it examines the concepts of duty, fear and courage in their medical setting; it deals with the historical aspects of the problem; it analyzes the role of social contract and professionalism; and it develops a viewpoint of the physician's obligation based on these considerations and predicated on a view of professionalism and social contract.
