目的 分析我国HIV-1 基因型的分布及变化趋势。方法 计算机检索中国医院知识总库(CHKD,1994-)、万方数据资源系统(1998-)、中国生物医学文献数据库(CBMDisc)以及PubMed数据库,并结合文献追溯的方法,收集我国HIV-1 基因分型的相关文献,提取符合标准的文献信息,对相同的HIV-1 亚型分别按地区、研究时间、研究人群分组,并进行数量合并,计算百分比。结果 共纳入175 篇文献,包含285 条记录。我国HIV-1 流行最广泛的毒株为CRF01_AE、CRF07_BC重组型,以及B’亚型,但不同地区基因亚型存在差异。北方地区流行毒株比较单一,且流行较稳定。南方地区HIV-1 毒株的亚型分布较为复杂,存在多种亚型及流行重组型,同时存在一定比例新的独特重组亚型流行。我国早期HIV-1 以B’及C亚型流行为主,近年来,尤其是2007 年以后,CRF01_AE重组型逐渐增高,成为我国优势毒株,同时存在一定比例的CRF07_BC、CRF08_BC重组型和B’亚型流行。结论 我国HIV-1 基因型地区分布、人群分布差异较大,且随着时间的推移,基因型分布产生较大的变化,流行更为复杂。 |

Objective To provide information on the geographical distribution of HIV-1 genotypes and subtypes in the population of China. Methods A comprehensive search was carried out in China Hospital Knowledge Database(CHKD),Wanfang(Chinese),CBMDisc and PubMed databases to identify all studies published related to HIV-1 genotypes in China. All studies were grouped according to the sites,period and objects for analyzing the distribution of HIV genotypes.Results A total of 175 studies were included in this Meta-analysis,which contained 285 records. We found that the predominate genotypes in China were B'subtype,CRF01_AE,CRF07_BC and CRF08_BC,but the subtype distribution of HIV-1 was different in the western and southern parts of the country. CRF01_AE had a significant increase while subtype B'showed a decrease. There were various HIV-1 subtypes among individuals who acquired HIV through sexual contacts and CRF01_AE was most commonly identified in this group of people. Conclusion The distribution of HIV-1 genotypes in Chinese people significantly changed,together with high complexity of the HIV-1 epidemics noticed in China. |
