摘要目的 观察肝脏祖细胞(hepatic progenitor cells,HPCs)在乙型肝炎肝硬化患者肝组织中的激活特征,探讨HBV感染是否影响HPCs的激活.方法 以细胞角蛋白(CK7)为标记,对16例乙型肝炎肝硬化患者的肝组织做免疫组织化学染色,定量分析HPCs数目及胆管反应面积.HBsAg和HBcAg染色,观察两种病毒蛋白的表达与HPCs激活的关系.结果 乙型肝炎肝硬化患者肝组织中HPCs激活程度高,胆管反应明显.肝组织中HBsAg的表达与HPCs激活程度呈正相关.结论 在乙型肝炎肝硬化患者的肝组织中,HPCs被明显激活和扩增,HBV感染可能参与HPCs的激活.

abstractsObjective To observe the characteristics of hepatic progenitor cells(HPCs)activation in liver tissues of patients with hepatitis B cirrhosis,and to investigate the relationship between the number of HPCs and HBV infection.Methods Cytokeratin 7(CK7)-was stained immunohistochemically in liver tissues of 16 patients with hepatitis B cirrhosis.HPCs and duetular reactions were quantitively analyzed.The expression of HBsAg and HBcAg were also detected to evaluate its relationship with HPCs activation.Results HPCs were extensively activated and marked duetular reactions can be observed in cirrhotic liver tissues.Tlle expression of HBsAg was positively correlated with HPCs activation.Conclusions HPCs are extensively activated in cirrhotic liver tissues,and HBV infection may facilitate its activation.
