摘要： 为了解广西近年确诊的HIV-1感染者流行病学及HIV-1亚型分布情况,分别在桂林、来宾、钦州采取样本100例、102例和103例,收集流行病学资料、采集抗凝全血、提取病毒RNA、用RT-PCR进行gag基因扩增并对产物进行测序和序列分析。结果显示:在305例样本中,男女性别比1.99∶1;青壮年年龄组患者占56.72%,>50岁年龄组患者构成比例为44.62%;职业为农民的患者比例为50.82%;初中及以下文化水平患者占76.39%;经异性性接触途径传播构成比为95.74%。最终成功扩增得到155份样本的gag基因序列,共发现4种亚型:CRF01-AE亚型 124例、CRF07-BC亚型12例、CRF08-BC亚型14例、B亚型5例。

Abstract: To determine the epidemiological situation of confirmed HIV-1 infections in Guangxi after 2008,and to understand the distribution of HIV-1 subtypes of Guangxi. An epidemiological survey was made on the HIV-1 infections confirmed after 2008. Among them, 100 come from Guilin, 102 from Laibin, and 103 from Qinzhou. HIV-1 RNA was extracted from their whole blood and amplified by RT-PCR. HIV-1 gag gene was sequenced directly from the PCR product.The results show that there are more men than women in the chosen patients, male to female ratio was 1.99:1.Patients aged ≥20 and ≤49 years old accounted for 56.72% in total, and patients aged 50 years old or older accounted for 44.62%. Farmers accounted for 50.82%.Patients with education level of junior school or below accounted for 76.39%. The patients′s proportion who were transmitted through heterosexual contact is 95.74%. 155 specimens are gained in 305 specimens(amplification rate of 50.82%), then sequence analysis showed that there were 4 HIV-1 subtypes, CRF01-AE(124 samples),B(5 samples),CRF-07BC(12 sample) and CRF-08BC(14 sample).

Key words: HIV-1, epidemiological characteristics, subtype, gag gene
