Acute-phase CD4 responses were efficient in self-limited infections but undetectable in the coinfected patient with HBV persistence. CD8 responses were multispecific irrespective of the outcome of infection, but the CD8 repertoire associated with HBV persistence lacked the most dominant specificities detectable in self-limited infections. In conclusion, insufficient CD4 help and defective CD8 repertoire may play a role at the early stages of infection in influencing HBV persistence.展开更多
目的:综合分析不同研究结果,探讨我国人群乙型肝炎病毒(hepatitis B virus,HBV)及丙型肝炎病毒(hepatitis C virus,HCV)重叠感染与肝癌的相关程度。方法:采用Meta分析,对我国2000年以来公开发表的有关HBV、HCV重叠感染和原发性肝癌关系...目的:综合分析不同研究结果,探讨我国人群乙型肝炎病毒(hepatitis B virus,HBV)及丙型肝炎病毒(hepatitis C virus,HCV)重叠感染与肝癌的相关程度。方法:采用Meta分析,对我国2000年以来公开发表的有关HBV、HCV重叠感染和原发性肝癌关系的18篇病例对照研究文献进行定量综合分析,利用Stata12.0中的Meta分析模块进行数据处理。发表偏倚的识别采用漏斗图和Egger's检验。结果:异质性检验发现:P=0.000,df=14,提示入选文献存在异质性。采用随机效应模型进行Meta分析,合并的OR为25.71(95%CI为12.50-52.89)。结论:HBV、HCV重叠感染与原发性肝癌的发生存在高度相关。展开更多
