摘要
目的探讨宣威地区谷胱苷肽硫转移酶(GSTM1)基因多态性与肺癌易感性的关系.方法选取宣威肺癌患者50例,正常对照组50例,采用聚合酶链式反应(PCR)和限制性片段长度多态性(RFLP)技术检测GSTM1的基因多态性.结果 GSTM1基因缺失型患肺癌的OR值为2.71(1.20~6.11),与对照组比较,差异有统计学意义(P<0.05).烧烟煤者发生肺癌的危险性升高(OR=3.78,P<0.01),结果发现缺失型基因且烧烟煤者患肺癌的风险明显增高OR值为9.23(2.24~38.29),经统计学检验,两组差别有统计学意义(P<0.01).结论 GSTM1基因缺失型患肺癌的危险性增加,烧烟煤者患肺癌的风险明显增高.
Objective To investigate the relationship between GSTM1genetic polymorphism and lung cancer susceptibility in Xuanwei,China.Method In a case-control study,PCR and RFLP was used to identify the genotypes of GSTM1 in 50 lung cancer cases and 50 controls.Results GSTM1 polymorphism showed frequency distribution differences,OR=2.71(1.20~6.11).There was a significant difference between the case group and the control group(P0.05).Using bituminous coal was strongly associated with the risk of lung cancer(OR=3.78,P0.01).People using bituminous coal with GSTM1(-/-)genotype had an odds ratio of lung cancer compared with people not using bituminous coal with GSTM1(+/+)genotype(OR=9.23(2.24~38.29,and there was a significant difference(P0.01).Conclusions GSTM1 null genotype increases the risk of lung cancer,Persons using bituminous coal with GSTM1 null genotype have higher risk of lung cancer.
