Abstract： 目的:探讨颗粒溶素(granulysin,GNLY)在原发性胆汁性肝硬化和患者(PBC)中的表达及其意义.方法:采用TaqMan探针技术,以18S rRNA为内参照,测定60例PBC患者外周血中GNLYmRNA的含量,同时应用酶联免疫吸附法(ELISA),检测PBC患者血清中GNLY蛋白的水平,并以健康体检组(n=100)和乙型肝炎肝硬化组(n=60)为对照.结果:PBC组GNLY mRNA的平均拷贝数显著高于健康对照组[(2.7±2.5)×108 vs (3.0±1.9)×107,P＜0.01]和乙型肝炎后肝硬化组[(2.7±2.5)×108 vs (4.7±3.6)×105,P＜0.001).PBC患者血清中的GNLY蛋白表达显著高于健康对照组(15.48±3.24 μg/L vs 4.76±2.32 μg/L,P＜0.01)和乙型肝炎后肝硬化组(1 5.48±3.24 μg/L vs 2.57±1.84 μg/L,P＜0.01).结论:GNLY的表达与PBC的发生、发展存在一定的相关性,可用于PBC临床诊断.
