摘要
目的:研究GSTT1+/0和GSTM1+/0基因型及其联合基因型与重度慢性牙周炎(chronic periodontitis,CP)易感性的关系。方法:用聚合酶链反应检测50例重度慢性牙周炎患者和51例正常对照者的GSTT1+/0、GSTM1+/0的基因型。结果:GSTM1(0/0)和GSTT1(0/0)基因型及GSTM1(0/0)与GSTT1(0/0)联合基因型对重度慢性牙周炎相对危险度(OR)分别为9.56(95%CI,3.88-23.59),8.68(95%CI,3.50-21.51),36.83(95%CI,10.42-130.13)。结论:在内蒙古汉族人群中,基因型GSTT1(0/0)和GSTM1(0/0)增加了个体对重度慢性牙周炎易感性,且上述两种基因型间存在协同作用。
Objective: To investigate the polymorphisms of GSTT1 and GSTM1 genes as well as their separate and combined effects on susceptibility to severe chronic periodontitis. Methods: In the 50 patients with chronic severe periedontitis and 51 healthy controls, the genotypes of GSTrl +/0 and GSTM1 +/0 polymorphisms were detected by PCR. Results: Individuals with genotype(0/0)of GSTM1, genotype(0/0) of GSTT1, combined genotypes GSTMI(0/0) and GSTT1(0/0)had more relative risks than those with the corresponding common genotypes, whose ratios were 9.56(95%CI 3.88-23.59), 8.68(95%CI 3.50-21.51), 36.83(95%CI 10.42- 130.13). Conclusion: There is a synergy of susceptible genotypes GSTM1 (0/0) and GSTT1(0/0) to enhance the individual susceptibility to chronic severe periedontitis.
