摘要

摘要: 探讨慢性乙型病毒性肝炎（CHB）患者肝组织中,α-SMA的表达对肝脏炎性损伤和肝纤维化程度的病理诊断意义。采用免疫组化技术,观察12 7例CHB患者肝穿刺组织中α-SMA的表达,结果与现行病理诊断标准慢性肝炎分级、分期及Knodell-HAI评分系统进行统计学比较。另有6例作为对照,其中急性肝炎3例,静止性肝硬化3例。α-SMA在CHB、急性肝炎及静止性硬化三组中均有表达。主要定位在扩大的汇管区及其周围,以及小叶内点灶状坏死部位。且α-SMA表达与慢性肝炎病理分级（G）、分期（S）及Knodell-HAI评分呈显著正相关。α-SMA是判断慢性乙型肝炎肝损伤程度及纤维化程度的一个重要指标。

Abstract: To study the expressio n of α-smooth-muscle actin and its pathological significance in evaluation of liver fibrosis and neeroinflammation of CHB.Liver biopsy specimens of 127cases of SHB were immunohistochemically stained for α-smooth-muscle actin (α-SMA) to compare the relationship of its expression with histological grading and staging of chro nic hepatitis and the histological activity index of Knodell.Another 6 cases, inc luding 3 cases of actue hepatitis and 3 cases of non-active cirrhosis respective ly, were chosen as controls.α-SMA was detected in all cases, either in CHB or in acute hepatitis and non-active cirrhosis.The cells positive for α-SMA increased around the enlarged portal areas mainly, as well as in some cases of lobular nea r focal necrosis and associated with progression of histological grading, staging and histological activity index of Knodell.α-SMA is an useful marker to judgem ent the degree of liver pathological changes not only for fibrosis but also for necroinflammation of CHB.
