摘要:
目的 研究国人血清对氧磷酶1(PON1)基因192位Gln/Arg多态性对冠心病患者血管内皮功能的影响。方法 应用聚合酶链式反应限制性片断长度多态性(PCRRFLP)方法,对石家庄地区汉族151例冠心病患者及91例正常对照者PON1基因192位Gln/Arg多态性进行分析,同时应用超声检测肱动脉内皮功能。结果 冠心病组及正常对照组PON1基因均以QR基因型为主,其频率分别为48%和54%。冠心病组RR型基因频率高于对照组(P<0.05)。平衡法计算等位基因的频率,R等位基因在冠心病组明显增高(65% vs 39%,P<0.05)。冠心病组PON1各基因型内皮依赖性舒张功能均低于对照组(P<0.05),以RR基因型最为明显,其次为QR基因性;而两组非内皮依赖性舒张功能差异无显著性。结论 PON1基因192位Gln/Arg多态性可能与冠心病患者血管内皮功能异常有关。R等位基因可能为血管内皮功能受损的相对危险因素,且参与冠心病的发病。
Abstract:
AIM To observe the effect of Paraoxonase (PON1) gene 192 Gln/Arg polymorphism on vascular endothelial function in patients with coronary heart disease in Chinese population. METHODS The genotype and allele frequency of PON1 gene 192 Gln/Arg polymorphism were assayed bypolymerase chain reaction (PCR)restriction fragment length polymorphism (RFLP) and the vascular endothelial function was examined with ultrasound technique in 151 CHD patients and 91 healthy subjects from a population of Chinese Han nationality in Shijiazhuang area. RESULTS In both CHD group and control group, PON1 gene was mostly of QR genotype and its frequencies were 48% and 54%. The frequency of R allele of PON1 gene in CHD group was significantly higher than that in control group (65% vs 39%, P<0.05). The CHD patients with individual PON1 genotype had a depressed endotheliumdependent vasodilation function and this was more significant in the RR genotype group. No difference endotheliumindependent vasodilation function was found between the two groups. CONCLUSION PON1 gene 192 Gln/Arg polymorphism may be associated with abnormal vascular endothelial function. R allele of PON1 gene may be a relative risk factor and be associated with the episode of CHD.
