【摘要】 目的：探讨胆固醇酯转运蛋白(CETP)基因Taq IB和-629C/A多态性与中国湖南地区汉族人群动脉粥样硬化性脑梗死的关联性,及其对血压、血脂、血糖等的影响。方法：应用聚合酶链反应-限制性片段长度多态性(PCR-RFLP)方法检测238例动脉粥样硬化性脑梗死患者和162例年龄、性别相匹配的健康体检者的CETP基因Taq IB和-629C/A多态位点的基因型分布和等位基因频率,血脂中甘油三酯(TG)和总胆固醇(TC)采用氧化酶法测定；高密度脂蛋白胆固醇(HDL-C)测定先用沉淀剂沉淀,再用酶法测定上清液中的胆固醇；低密度脂蛋白胆固醇(LDL-C)由公式(LDL-C)=(TC)-(HDL-C)-(TG/5)求出；血糖(FBS)用葡萄糖氧化酶法测定。实验数据用SPSS13.0软件进行统计分析。结果：1.中国湖南汉族人群脑梗死组与对照组CETP基因Taq IB多态B1B1、B1B2. B2B2三种基因型频率及B1、B2等位基因频率的比较无显著性差异(P>0.05)。2.中国湖南汉族人群脑梗死组与对照组CETP基因-629C/A多态AA, AC、CC三种基因型频率及A、C等位基因频率的比较无显著性差异(P>0.05)。3.Taq IB脑梗死组B1B1基因型血脂、血糖、收缩压、舒张压及高血压、冠心病、糖尿病病史与B1B2+B2B2基因型比较无显著性差异(P>0.05)。4.-629C/A脑梗死组CC基因型血脂、血糖、收缩压、舒张压及高血压、糖尿病病史与CA+AA基因型比较无显著性差异(P>0.05),CC基因型与CA+AA基因型间冠心病病史比较差异有统计学意义(P<0.05)。5.脑梗死组各联合基因型间血脂、血糖、收缩压、舒张压及高血压、冠心病、糖尿病病史比较无显著性差异(P>0.05)。结论：1. CETP基因Taq IB和-629C/A多态性可能与中国湖南汉族人群的动脉粥样硬化性脑梗死发病无关。2. CETP基因Taq IB和-629C/A多态性可能与中国湖南汉族人群的血脂、血糖、血压水平无关。3. CETP基因Taq IB和-629C/A两位点的联合基因型可能与中国湖南汉族人群的血脂、血糖、血压水平无关。更多还原

【Abstract】 Objective To explore the association of cholesterol ester transfer protein gene Taq IB and -629C/A polymorphism with atherosclerosis cerebral infarction (CI) in Han population in Hunan province, and the possible influence of this SNP on blood pressure, serum lipid and fasting glucose.Methods Polymerase chain reaction-restriction fragment length polymorph (PCR-RFLP) was performed to identify the distributions of allele and genotype frequencies of SNP Taq IB and -629C/A polymorphism in cholesterol ester transfer protein gene in 238 patients with atherosclerosis CI and 162 healthy controls. Meanwhile we tested the levels of blood pressure, serum lipid, fasting glucose and BMI. All data was analyzed by SPSS 13.0.Results1. There is no significant difference of CETP Taq IB gene B1B1, B1B2, B2B2 genotype and B1 or B2 allelic distribution between CI patients and controls (P>0.05).2. There is no significant difference of CETP -629C/A gene AC, AC, CC genotype and A or C allelic distribution between CI patients and controls (P>0.05).3.The difference of blood lipids, blood sugar(FBS),blood pressure, history of hypertension, coronary heart disease, diabetes between CETP Taq IB B1B1 and B1B2+B2B2 gene type are not significant(P>0.05).4.The difference of blood lipids, blood sugar(FBS),blood pressure, history of hypertension or diabetes between CETP -629C/A CC and CA+AA gene type are not significant(P>0.05). History of coronary heart disease in CC genotype compared CA+AA genotypes were significantly (P<0.05).5. There are no significant differences between 4 combined gene types in lipids, glucose, blood pressure and history of hypertension, coronary heart disease, diabetes mellitus (P> 0.05).Conclusions1. The Taq IB and -629C/A polymorphism of CETP gene may not correlate with atherosclerosis cerebral infarction in Chinese Han population in Hunan province.2. There is no relationship between Taq IB polymorphism of CETP gene and blood lipids, FBS or blood pressure in Chinese Han population in Hunan province. The same to -629C/A polymorphism of CETP gene.3. There is no relationship between the polymorphism of Taq IB and -629C/A combined genotype and blood lipids, FBS or blood pressure in Chinese Han population in Hunan province.更多还原
