中国面临着两种HIV - 1流行重组形式(CRFs)07_BC和08_BC日益流行的情况。此前已证明这两种CRFs_BC都起源于云南,并通过中国的注射吸毒(IDU)从云南传播到辽宁。假设这是真的,我们无法回答为什么只有CRF07_BC,而不是两种CRFs_BC一起,被传播到新疆。 我们使用贝叶斯系统发育地理学方法对多个HIV - 1基因组区域的CRF07_BC和CRF08_BC进行系统发育地理学研究。系统发育重建显示,所有CRF07_BC序列分为两个分支,云南分支和新疆分支,来自中国大陆其他地区的所有毒株都聚集在新疆分支内。贝叶斯因子检验支持新疆与其他地区(包括辽宁、北京、江苏和广东)之间存在显著的地理扩散联系。时间动态分析显示,CRF07_BC于1996年10月从新疆传播到辽宁,并于2000年9月传播到江苏。对CRF08_BC的分析不仅证实了先前关于CRF08_BC时空动态的结论,还表明来自广东和上海的CRF08_BC毒株起源于云南。对丙型肝炎病毒(HCV)3a的分析显示,它于20世纪80年代初传入新疆,并于1990年10月从新疆传播到云南,于1999年2月传播到江苏,进一步于1995年3月从云南传播到广西。HCV 3a的时空动态在一定程度上与HIV - 1的CRF07_BC和/或CRF08_BC相似,这表明通过注射吸毒,HCV和HIV - 1在传播模式上可能存在关联。此外,HCV 3a从新疆传播到巴基斯坦,这意味着存在一条将它们联系起来的贩毒路线。 新疆作为从金新月地区向中国其他地区贩毒的最重要中转站,在亚洲通过注射吸毒传播病毒(如HIV - 1和HCV)方面起着非常关键的作用。
Background China faces an increasing prevalence of two HIV-1 circulating recombinant forms (CRFs) 07_BC and 08_BC. Both CRFs_BC were previously demonstrated to originate in Yunnan and spread to Liaoning from Yunnan via injection drug use (IDU) in China. Supposing it is true, we are unable to answer why only CRF07_BC, rather than both CRFs_BC together, was transmitted to Xinjiang. Methodology/Principal Findings We investigated the phylogeography of CRF07_BC and CRF08_BC using multiple HIV-1 genomic regions with Bayesian phylogeography method. Phylogenetic reconstructions showed that all CRF07_BC sequences were divided into two clades, Yunnan and Xinjiang, and all strains from other regions of mainland China clustered within the Xinjiang clade. Significant geographic diffusion links of Xinjiang with other regions (including Liaoning, Beijing, Jiangsu and Guangdong) were supported by Bayes factor tests. The temporal dynamics analyses showed that CRF07_BC spread from Xinjiang to Liaoning in 1996.10, and to Jiangsu in 2000.9. The analyses of CRF08_BC not only confirmed the previous conclusion on temporal and spatial dynamics of CRF08_BC, but also indicated that the CRF08_BC strains from Guangdong and Shanghai originated from Yunnan. The analyses of HCV 3a showed that it was introduced into Xinjiang in the early 1980s, and spread from Xinjiang to Yunnan in 1990.10 and to Jiangsu in 1999.2, and further from Yunnan to Guangxi in 1995.3. The temporal and spatial dynamics of HCV 3a were similar to some extent to that of HIV-1 CRF07_BC and/or CRF08_BC, suggesting a possible association in migration patterns between HCV and HIV-1 through IDU. In addition, HCV 3a spread from Xinjiang to Pakistan, implying a drug trafficking route linking them. Conclusions/Significance Xinjiang, as the most important transfer station for drug trafficking from Golden Crescent to other regions of China, plays a very crucial role in the transmission of viruses (e.g., HIV-1 and HCV) through IDU in Asia.
