摘要(Abstract)：
目的 分析HIV感染者/AIDS病人体内病毒复制和免疫功能变化及其与病程发展的关系。方法 应用定量RT-PCR、流式细胞计数和定量ELISA 方法分析55例HIV感染者（n=42）和AIDS病人（n=13）外周血血浆病毒载量、T淋巴细胞亚群和细胞因子浓度。结果 HIV感染者和 AIDS病人CD4细胞和血浆IL-2浓度低于正常人群（P<0.001）,血浆 sIL-2R、TNF-α、NPT浓度高于正常人群（P<0.01）;AIDS病人CD4细胞和IL-2浓度明显低于HIV感染者（P<0.001）,而血浆病毒载量、sIL、-2R、TNF-α、sTNFR-I、NPT浓度明显高于HIV感染者（P<0.01）,且随着CD4细胞水平降低呈明显上升趋势。CD4细胞、CD4/CD8比值和血浆IL-2水平随感染时间延长而不断下降,不同感染时间之间差异明显;机体感染HIV后CD4细胞年平均下降43/mm3,血浆sIL-2R、sTNFR-I、NPT年平均上升幅度分别为59.03pg/ml、38.69pg/ml、2.11ng/ml。各因素相关性分析显示:CD4细胞、CD4/CD8比值与感染时间,CD3、CD4、CD8细胞变化分别与血浆病毒载量、sTNFR-I、NPT之间有高度负直线相关性;而血浆sIL-2R分别与IL-6（P<0.001）、IL-10（P<0.001）、TNF-α（P<0.001）、sTNFR-I（P<0.005）、NPT（P<0.002）浓度变化间,以及IL-6与TNF-α（P<0.001）、NPT与IL-10（P<0.05）和 sTNFR-I（P<0.001）,?
