摘要

目的:探讨某地区人类免疫缺陷病毒 (HIV) 感染者中的人白细胞抗原 HLA-B*5701 阳性率。方法:采用荧光
原位杂交技术(FISH),即根据碱基互补配对原则,通过带有荧光物质的探针与目标 DNA 结合,最后通过观察荧光信号
确定基因型,对 HLA-B*57:01 阳性率数据进行比较,设检验水准 α=0.05,用 SPASS26.0 软件做卡方检验。结果:353 名
HIV-1 阳性感染者中,13 人携带 HLA-B*57:01 等位基因,阳性率为 3.68%;其中汉族人 150 人,5 人携带 HLA-B*57:01
等位基因,阳性率为 3.33%;其他民族 203 人,8 人携带 HLA-B*57:01 等位基因,阳性率为 3.94%。结论:人群感染
HIV-1 的感染者中 HLA-B*57:01 阳性率低于国外黑种人和白种人的研究数据,但和我国其他省份地区的数据相比较较高。
