Abstract： 目的:通过检测乙型肝炎患者外周血单核细胞各亚群分布情况以及HLA-DR表达水平,探讨慢性乙型肝炎患者外周血中CD14+CD16+单核细胞及HLA-DR的表达特点,以及与疾病进程之间的关系.方法:利用流式细胞仪(FCM) 检测50例慢性乙型肝炎患者,其中21例免疫耐受(IT)患者、29例免疫活化(IA)患者,及31例正常人外周血CD14、CD16、HLA-DR的表达.同时调查肝功能、乙肝五项和血清HBV DNA等相应临床资料.结果:免疫活化组(IA)的CD14+CD16+亚群比率明显高于正常对照组和免疫耐受组(IT)(P<0.01);单核细胞CD14+CD16+亚群HLA-DR表达明显高于CD14++CD16-亚群(P<0.01);乙型肝炎患者CD14+CD16+单核细胞比率与ALT呈正相关(r=0.876,P<0.01),与HBV DNA载量成负相关(r=-0.267,P<0.01).结论:CD14+CD16+单核细胞可能在乙型肝炎患者外周血中参与调节针对HBV的免疫反应,CD14+CD16+单核细胞与HBV复制和肝脏炎症之间存在相关性,因此检测单核细胞CD14+CD16+亚群及HLA-DR水平对于了解乙型肝炎患者疾病进程具有重要的临床应用价值.
