2、DNA载量。结果CHB组仅CD4+亚群明显降低,与对照纽比较,差异有统计学意义(P<0.05);CSHB及Lc组CD3、CD4亚群、CD;/CD8+比值呈逐渐降低趋势,CDs亚群呈逐渐增高趋势,与对照组比较差异有统计学意义(P<0.05)。HBVDNA裁量与CD4+亚群、CD;/CD8+比值呈负相关(r=一0.638,一0.778,P<0.05),与CDs亚群呈正相关(r:0.647,P<0.05),与cD无关。与HBeAg阳性患者比较,HBeAg阴性患者外周血cD3、CD;和CD8亚群显著降低(P<0.05)。结论慢性HBV感染者随着疾病加重细胞免疫功能进行性降低,
3、与病毒复制水平密切相关,这是导致疾病慢性化的原因之一。外周血T细胞亚群变化趋势可为判断疾病转归及预后提供可靠指标。【关键词】乙型肝炎病毒;慢性肝炎;T细胞亚群【中图分类号】R512.62【文献标识码】A【文章编号】1002—7386(2014)13—1940—03ThecorrelationbetweenTlymphocytesubsetsinperipheralbloodandHBVDNAlevelsaswellasHBeAginpatients、vithchronichepatitisBvirusinfectionUKun,YANGYaping,DUANYinhu
