Abstract
目的:探讨CCR2基因-190 G/A和CCR5基因-59029 G/A单核苷酸多态性( SNP)与结核性脓胸的关系。方法采用聚合酶链反应—限制性片段长度多态性( PCR-RFLP)方法对结核性脓胸患者300例和健康对照组300例进行CCR2基因-190 G/A和CCR5基因-59029 G/A SNPs检测。结果与CCR2基因-190 GG基因型相比,携带AG和AA基因型均可增加结核性脓胸发病风险( OR=2.254,95%CI 1.043~4.868;OR=8.728,95%CI 4.224~18.033)。进行分层分析发现,无卡介苗( BCG)接种史、体质量指数( BMI)<18.5 kg/m2均增加结核性脓胸发病风险(OR=3.309,95%CI 2.108~4.382;OR=2.767,95%CI 1.918~3.993)。 CCR5基因-59029 G/A 各基因型未入选回归方程,无统计学意义( P >0.05)。结论 CCR2基因-190 G/A SNP可能与结核性脓胸的发病风险有关;CCR5基因-59029 G/A SNP可能与结核性脓胸无关。
