乙醛脱氢酶2与饮酒和HBsAg致肝癌交互作用*

Interaction between polymorphisms of aldehyde dehydrogenase-2 genotypes and drinking habit as well as liver neoplasms caused by HBsAg

    摘要
  • 摘要:
      目的   研究乙醛脱氢酶-2(ALDH2)基因多态性与饮酒习惯和HBsAg致肝癌的交互作用。
      方法   选择88例新发肝癌病人按性别、年龄和居住地进行1:1配对流行病学调查。病例和对照均采集静脉血, 用PCR-RFLP法检测研究对象的ALDH2基因型, 用ELISA法检测血中乙型肝炎病毒表面抗原(HBsAg).
      结果   病例组(36.40%)与对照组(35.22%)ALDH2变异基因型(G/L+L/L)的分布频率无显着性差异; 但HBsAg阳性率病例组(72.73%)显着高于对照组(22.73%); 大量饮酒、HBsAg阳性与ALDH变异基因型的交互作用指数分别为0.8320和0.6634.
      结论   乙醛脱氢酶2变异基因型与大量饮酒和HBsAg阳性致肝癌发生有显着的交互作用。携带ALDH2变异基因型者大量饮酒将显着增加患肝癌的危险性。

     

    Abstract:
      Objective   To study the interaction between drinking habit and HBsAg with polymorphisms of aldehyde dehydrogenase-2(ALDH2)geno types in liver cancer.
      Methods   Acase-control study including 88 cases of newly diagnosed liver cancer and 88 controls matched on sex, age and resident area was carried out, blood samples from all individuals were collected and tested for ALDH2 genotypes by PCR-RFLP method as well as for HBsAg by ELISA method.
      Results   The frequencies of ALDH2 variant genot ypes(G/L+L/L)in cases and controls were 36.40% and 35.22%, and no difference was found between these two groups.The positive rates of HBsAg between cases and controls showed differences, much higher in cases(72.73%)than those in controls(22.73%).This study showed interactions index of large amount of alcohol consumption and positive rates of HBsAg with ALDH variant genotypes were 0.8320 and 0.6634, respectively.
      Conclusion   The study showed significant interaction between large amount of alcohol consumption and positive rates of HBsAg with ALDH variant genotypes, and revealed a strong relation between polymorphisms of ALDH2 genotypes and heavy alcohol consumption for susceptibility of liver cancer.
