应用人体微量外周血微核测试方法对６７例ＨＢｓＡｇ阳性肝癌，肝硬化患者进行微核率观察，结果观察组微核率明显高于对照组，（Ｐ＜００１）呈非常显著性差异，而肝癌组与肝硬化组相比也有非常显著性差异，Ｐ＜０００１ Micronucleus rate was observed in 67 patients with HBsAg-positive liver cancer and liver cirrhosis using the human peripheral blood micronucleus test method. The micronucleus rate of the observation group was significantly higher than that of the control group (P<001). There was a very significant difference. There was also a significant difference between the liver cancer group and the liver cirrhosis group. P<0001
