Methods: The CETP gene rs1532624 and rs289741 in 95 patients with ACI and 177 healthy subjects were genotyped by Mass ARRAY mass spectrometry. Each locus genotype and allele frequency distributions were compared. Results: The difference of allele frequency distribution between the rs1532624(χ~2=1.723, P=0.189) and rs289741(χ~2=2.466, P=0.116) were not statistically significant. The frequency distribution of rs1532624 genotype between the cerebral infarction group and healthy control group was statistically significant(χ~2=7.096, P=0.029), while rs289741 genotype frequency distribution between the two groups was not statistically significant(χ~2=2.906, P=0.234). Conclusion: ACI have a positive correlation with rs1532624 polymorphism, and AA genotype may be susceptible factors of ACI.展开更多

目的探讨胆固醇酯转运蛋白(cholesteryl ester transfer protein,CETP)基因TaqIB多态性与粤西地区高脂血症患者他汀类药物治疗效果之间的关系。方法PCR扩增140例高脂血症患者TaqIB多态位点相应的DNA片段,经限制性内切酶消化并电泳后确...目的探讨胆固醇酯转运蛋白(cholesteryl ester transfer protein,CETP)基因TaqIB多态性与粤西地区高脂血症患者他汀类药物治疗效果之间的关系。方法PCR扩增140例高脂血症患者TaqIB多态位点相应的DNA片段,经限制性内切酶消化并电泳后确定基因型,用SPSS10.0软件采用ANO VA检验进行统计学分析。结果TaqIB多态B1B2基因型个体的甘油三酯(triglyceride,TG)基线水平比B2B2基因型个体明显高出0.65mmol/L(P=0.041),B2B2基因型个体的高密度脂蛋白胆固醇(high density lipoprotein,HDL-C)基线水平分别比B1B1个体和B1B2个体明显高出0.58mmol/L(P=0.000)和0.62mmol/L(P=0.000)。高脂血症患者经辛伐他汀治疗4周后HDL-C和低密度脂蛋白胆固醇(low densi-ty lipoprotein cholesterol,LDL-C)水平变化量在TaqIB多态位点不同基因型间的3组间差异有统计学意义(F=6.120,P=0.003;F=3.925,P=0.022)。Post Hoc多重比较结果表明,B1B2基因型个体的HDL-C水平升高值较B2B2基因型个体明显增多0.24mmol/L(P=0.003),B1B2基因型个体LDL-C水平降低值比B1B1个体明显减少0.25mmol/L(P=0.024)。结论B1B1和B1B2基因型个体他汀类药物调脂效果较好,而B2B2个体对他汀类药物治疗反应较弱,胆固醇酯转运蛋白基因TaqIB多态可能是预测中国粤西地区高脂血症患者他汀类药物调脂效果个体化差异的标记物之一,具有一定的临床意义。展开更多
