Objective:To assess the correlation between the HBx gene integration in hepatocyte chromosome and HCC generation, investigate the difference of hepatitis B virus serum markers between patients with HCC and CHB, and to investigate the correlation between HBx gene integration and hepatitis B virus serum markers. Methods:Hepatocyte samples obtained from 19 patients with hepatocyte carcinoma or 14 subjects with chronic hepatitis B were prepared. The frequency of HBx gene integration was detected using biotin-marked HBx probe. Then the results were analyzed combining with the clinical data of hepatitis B virus serum markers.Results:①Among 19 patients with HCC, 13 subjects were found the signals of HBx gene hybridization in mitotic chromosome of tumour,which occupied 68.24% and was more than that in CHB(28.57%)(-字2 = 5.12,P < 0.05). The HBx integration sites were 3.8 ± 1.36 in hepatocyte chromosome of HCC and 1.3 ± 0.36 in CHB,respectively(t = 3.5,P < 0.01). ②The positive rate of HBeAg in serum was 80.0% in CHB,which is much higher than that in HCC(10.53%). There was a significant difference(-字2 = 6.33,P < 0.01) between those two groups. ③There were no correlation between the frequency of HBx integration and the clinical hepatitis B virus serum marks either in HCC or in CHB. Conclusion:The frequency of HBx gene integration in HCC is higher than that in CHB. HBV reproducing in patients with CHB is more active than that with HCC.
