title: [Preventive and therapeutic effects of qiongyugao on hepatocellular carcinoma via inhibition of the expression of HBxAg in hepatic carcinoma cells].
abstract: OBJECTIVE
  To investigate the effects of qiongyugao on the expression of hepatitis B x antigen (HBxAg) in BALB/c-nu mice into which human hepatic carcinoma cells were transplanted, and to analyze its specific mechanism in prophylaxis and treatment of hepatocellular carcinoma.
  
  
  METHODS
  A nude mouse model with the transplantation of human hepatic carcinoma cells was established to observe the preventive and therapeutic effects of qiongyugao on the body weight and tumor weight of the mice. The expression of HBxAg in tumor and liver tissue wsa detected by immunohistochemical studies.
  
  
  RESULTS
  Compared with model control group, prophylaxis and treatment with qiongyugao increased the body weight, depressed the tumor weight and inhibited HBxAg expression. The same efficacy was showed in both qiongyugao prophylaxis group and cyclophosphamide treatment group.
  
  
  CONCLUSIONS
  Qiongyugao can slow down the growth of tumor and inhibit the expression of HBxAg, which may be an essential mechanism in prophylaxis and treatment of hepatocellular carcinoma.
