Objective  To study the relationship of hepatocyte apoptosis and gene expression of liver cirrhosis and primary hepatic carcinoma. Methods  Specimens of liver tissue from patients with liver cirrhosis and portal   hypertension   and normal subjects were examined by transmission electron microscope to detect apoptotic cells and primary cancer gene expression. Results  The number of apoptotic cells and the apoptotic index of cirrhotic liver   tissue   was higher than that of normal subjects.Immunostaining of bcl  2,c  myc,c  fos was negative in normal liver   tissue  ,but was over  expressed in cirrhosis. Conclusions   Hepatocyte apoptosis plays a certain role in the   development   of hepatic cirrhosis. The oncogenes bcl  2,c  myc,c  fos take part in the regulation of hepatocyte   apoptosis  .
