目的 探讨中国汉族人群血栓素A2受体(TXA2R)基因启动子m2271875、m768963位点的多态性与急性脑梗死的关系.方法 采用前瞻性研究方法,选择2009年10月至2013年5月浙江省台州市中心医院223例脑梗死患者(脑梗死组)及142例门诊体检正常者(健康对照组).采用酶比色法检测甘油三酯(TG)、总胆固醇(TC)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C);采用己糖激酶法测定血糖;采用聚合酶链反应-连接酶检测反应(PCR-LDR)技术检测TXA2R基因启动子rs2271875、rs768963位点多态性的基因型.比较两组在性别、年龄、血清TG、TC、HDL-C、LDL-C、血糖水平及收缩压、舒张压方面的差异;比较两组TXA2R基因启动子rs2271875、rs768963基因型、等位基因频率的分布差异.结果 脑梗死组男性例数(例:147比57,Х^2=23.385,P=0.000)、血清TG(mmol/L:2.02±1.14比1.56±0.79,t=4.663,P=0.000)、血糖(mmol/L:6.40±2.50比5.28±0.92,t=6.084,P=0.000)、收缩压[mmHg(1mmHg=0.133 kPa):146.64±21.34比135.73±18.09,t=5.234,P=0.000]、舒张压(mmHg:86.29±11.79比80.74±11.23,t=4.468,P=0.000)与健康对照组比较差异均有统计学意义.Logistic多元逐步回归分析显示,男性是脑梗死的危险因素[优势比(OR)=3.300,95%可信区间(95% CI) 1.905 ~ 5.175,P=0.000].与健康对照组相比,脑梗死组TxA2R基因rs768963基因型(TT:0.112比0.183,TC:0.498比0.535,CC:0.390比0.282,Х^2=6.298,P=0.043)及等位基因频率(T:0.361比0.451,C:0.639比0.549,Х^2=5.839,P=0.016)分布差异有统计学意义;而rs2271875位点基因型(GG:0.336比0.352,GA:0.480比0.451,AA:0.184比0.197,Х^2=0.302,P=0.859)及等位基因频率(G:0.576比0.577,A:0.424比0.423,Х^2=0.001,P=0.974)分布差异无统计学意义.rs2271875与rs768963的连锁不平衡系数(D’)为0.684.rs2271875(A)与rs768963(T)配对呈单倍型AT时,在脑梗死组中的出�
Objective To investigate the association between thromboxane A2 receptor (TXA2R) gene promoter rs2271875,rs768963 polymorphism and acute cerebral infarction in Chinese Han population.Methods A prospective study was conducted.From October 2009 to May 2013,223 patients with cerebral infarction (cerebral infarction group) and 142 cohorts with normal physical examination resuhs (control group) from Taizhou City Central Hospital in Zhejiang Province were enrolled.Triglyceride (TG),total cholesterol (TC),high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) were determined by enzymatic colorimetry,whereas blood glucose was determined with hexokinase.The genotypes of rs2271875 and rs768963 polymorphism in TXA2R gene were detected by the polymerase chain reaction-ligase detection reaction (PCR-LDR) technique.Differences in gender,age,serum TG,TC,HDL-C,LDL-C,concentration of blood glucose,and blood pressure (systohc pressure,diastolic pressure) between cerebral infarction group and control group were compared as well as TXA2R promoter rs2271875,rs768963 genotype and allele frequencies distribution.Results The significant differences in males(cases:147 vs.57,Х^2=23.385,P=0.000),serum TG (mmol/L:2.02 ± 1.14 vs.1.56 ± 0.79,t=4.663,P=0.000),blood glucose (mmol/L:6.40 ± 2.50 vs.5.28 ±0.92,t=6.084,P=0.000),systolic pressure [mmHg (1 mmHg=0.133 kPa):146.64 ± 21.34 vs.135.73 ± 18.09,t=5.234,P=0.000],diastolic blood pressure (mmHg:86.29 ± 11.79 vs.80.74 ± 11.23,t=4.468,P=0.000) between cerebral infarction patients and controls were found.The results from multi-logistic regression analysis suggested that male was an independent risk factor for cerebral infarction [odds ratio (OR) 3.300,95% confidence interval (95%CI) 1.905-5.175,P=0.000].There were statistically significant differences between infarction group and the control group both in aspects of genotype (TT:0.112 vs.0.183,TC:0.498 vs.0.535,CC:0.390
