摘  要:目的分析血栓素合酶基因(CYP5AI)Rsl0087667多态性与新疆维吾尔族心肌梗死(MI)的相关性。方法采用聚合酶链反应-限制性片段长度多态性方法,对318例MI患者(MI组)和232名健康受试者(对照组)CYP5A1基因Rsl0487667位点进行检测,同时进行血清血栓素(TXB2)水平测定。采用非条件多元logistic回归分析综合评价各因素与MI的关系。结果CYP5A1基因Rsl0087667在MI组和健康对照组中基因型频率分别为:GG型0.200(65/318)和0.155(36/232),GT型0.553(176/318)和0.466(106/232),TT1型0.242(77/318)和0.379(88/232),两组GG基因型差异具有统计学意义(χ^2=12.193,P=0.002),且MI组G等位基因频率[0.481(306/636)]高于对照组[0.388(180/464)](χ^2=9.449,P=0.021),而GT和TT基因型差异无统计学意义(χ^2=0.699,P〉0.05);MI组血清TXB2水平[(184.3±34.7)pg/m1]明显高于对照组[(124.3±28.1)pg/ml],差异具有统计学意义(t=5.503,P=0.034);MI组和对照组GT+GG基因型TXB2水平分别为(164.21±22.56)、(134.26±19.83)pg/ml,均较TT基因型者[分别为(113.67±54.23)、(98.54±13.11)pg/ml]增高,差异具有统计学意义(t值分别为5.433、5.108,P值均〈0.05)。logistic回归分析显示,调整传统危险因素的干扰后,CYP5A1G等位基因仍为MT的独立危险因素(OR=1.673;95%CI:1.020~2.156)。结论CYP5A1基因Rsl0487667基因多态性和新疆维吾尔族MT的发生具有相关性,可能和基因变异导致的血清TXB,水平升高有关。Objective To investigate the association between the polymorphism of thromboxane synthase gene (CYPSA1) and myocardial infarction (MI) of Uigur nationality patients in Xinjiang. Methods Rs10487667 site polymorphism in CYP5 AI gene of 318 patients with MI (MI group) and 232 healthy control subjects (control group) were analyzed by polymerase chain reaction and restriction fragment length polymorphism. The sermn thromboxane B2 ( TXB2 ) concentration was also detected in all subjects. The relationship of multiple factors and myocardial infarction was evaluated comprehensively by non-condition logistic regression analysis. Results The frequencies of CYP5A1 gene Rs10487667 site polymorphism in MI group and eontrol group were: GG type 0. 204(65/318) and 0. 155(36/232) ,GT type 0. 553(176/318) and 0. 466 ( 106/232 ), TT type 0. 242 ( 77/318 ) and 0. 379 ( 88/232 ), respectively. There was significant difference in frequencies of GG geuotype ( χ^2 = 12. 193, P = 0. 002) between two groups and G allele frequency in MI group (0. 481 (306/636)) was significant higher than control group (0. 388 (180/464) ) (χ^2 = 9. 449 ,P =0. 021 ),but no difference in frequencies of GT and TT genotypes (χ^2 = 0. 699, P 〉 0. 05 ) between controls and MI cases. There was significant difference in serum TXBz level between MI( ( 184. 3±34. 7) pg/ml) and control ( ( 124. 3 ±28. 1 ) pg/ml) groups(t =5. 503 ,P =0. 034). In the ease and control group,the serum TXB2 level of the person with GT + GG gcnotype ( ( 164. 21 ± 22.56) and ( 134. 26 ± 19. 83) pg/ml) ) was significant higher than those of TT genotypes ( ( 113.67±54. 23 ) and (98.54 ±13.11 ) pg/ml) ( t values were 5. 433 and 5. 108, respectively, both P values 〈 0. 05 ). Logistic regression analysis showed that the T allele of the CYPSAI gene was one independent risk factor of MI( OR = 1. 673, 95% CI: 1. 020 - 2. 156) after adjustment of risk factor
