简介：T房间受体贝它链的侧面变量(TRBV)基因通常与病毒感染或癌症在题目扭曲。融化的基因光谱模式(GMSP)能被用来决定TRBV基因家庭的侧面。从从尖锐肝炎B病毒感染(AHI)恢复了的题目在外部血淋巴细胞探索TRBV家庭的肖像，外部血mononuclear房间(PBMC)被分开并且进一步排序+和CD8+T房间子集进CD4。TRBV的分子的特征补足的决定区域3(CDR3)主题用GMSP分析被决定。当GMSP侧面显示出一座单个山峰时，monoclonally扩展的TRBV基因被克隆并且定序。多重TRBV基因的扭曲的扩大在CD4+和CD8+T房间子集和PBMC之中被观察。在CD8+T房间子集的monoclonally扩展的TRBV基因的频率比CD4+T房间子集和PBMC的显著地高。比作TRBV基因家庭，TRBV11，BV15和BV20的另外的成员主要在恢复AHI题目在外部血淋巴细胞的全部剧目被表示。TRBV5.1和BV20CDR3的相对保存的氨基酸主题也在CD4+和CD8+T房间子集被检测。这些结果在恢复AHI题目表明多重偏导的TRBV家庭的存在。特别从CD8+T房间子集，TRBV11，BV15和BV20可能与有AHI的题目的致病相关。有相对保存的CDR3主题的优先地选择的TRBV5.1和BV20可以是为长期的HBV感染的个性化的处理的潜在的目标。

简介：AbstractBackground:Human immunodeficiency virus (HIV) prevalence among student men who have sex with men (MSM) in college is more than 5.0% and keeps on increasing in China. This study aims to clarify the proportion of HIV recent infection, its propeller and the source among college student MSM.Methods:We conducted a multicenter cross-sectional study in seven major Chinese cities during 2012-2013. HIV recent infections (≤168 days) and incidence was measured and estimated by BED HIV-1 capture enzyme immunoassay (BED-CEIA) testing strategy. HIV-related behaviors and transmitted drug resistance (TDR) were investigated and compared between the college student MSM, < 25-year-old non-student youth MSM (NSYM), and ≥25-year-old non-student non-youth MSM (NSNYM), using structured survey, and analyses of drug resistance.Results:Overall, 4496 (4496/4526, 99.3%) were eligible for enrollment, comprising 565 college student MSM, 1094 NSYM, and 2837 NSNYM. The proportion of HIV recent infection were 70.3% (26/37), 50.8% (65/128) and 35.1% (95/271), the HIV incidence rate were 10.0 (95% CI: 6.2-13.9)/100 person-year (PY), 12.9 (95% CI: 9.8-16.1 )/100PY, 6.8 (95% CI: 5.4-8.2)/100 PY, and TDR prevalences were 7.4% (2/27), 2.0%, (2/98) and 4.9% (11/226), among student MSM, NSYM, and NSNYM, respectively. Among HIV positive student MSM with age <21 years, the proportion of HIV recent infection is 90.9% (10/11). Factors independently associated with HIV recent infection in student MSM was usage of recreational drug in the past 6 months (adjusted odds ratio [aOR]: 2.5; 95% CI: 1.0-5.8).Conclusions:College student MSM had higher proportion of HIV recent infection and TDR than the youth and older MSM in China during 2012-2013. The HIV infections were more likely to happen during the early year of college life among student MSM.
