摘  要:目的分析血小板二磷酸腺苷(ADP)受体P2Y,和P2Y12基因多态性是否对阿司匹林抗血小板作用产生影响。方法入选服用阿司匹林(75~100mg/d,≥1个月)的缺血性心脑血管病患者431例,根据阿司匹林抵抗(AR)诊断标准,分为AR组59例,非AR组372例,并使用美国Sequenom系统单核苷酸多态性分型技术对P2Y,rs1065776(893C〉T)和P2Y12rs5853517(i-ins801A,H1/H2单体型)2个位点进行鉴定和分析。结果AR组血肌酐明显高于非AR组[(92.82±83.07)umol/L vs(78.75±20.41)μmol/L,P=0.01]。2组P2Y1rsl065776突变T等位基因频率分布比较,差异无统计学意义(P〉0.05)。2组携带突变等位基因T的TT+CT基因型与野生型纯合子CC基因型比较,差异无统计学意义(P〉0.05)。2组P2Y12 H1/H2单体型和突变的H2单体型频率分布比较,差异无统计学意义(P〉0.05)。2组携带突变等住基因H2的H2/H2+H2/HI基因型与野生型纯合子H1/H1基因型比较,差异无统计学意义(P〉0.05)。结论老年心脑血管病患者AR与血小板ADP受体P2Y1和P2Y12常见的基因多态性无相关性。Objective To study whether platelet adenosine diphosphate (ADP) receptor P2Y1 and P2YI~ gene polymorphism influences the aspirin resistance (AR) to platelets. Methods Four hun- dred and thirty-one cardio-cerebrovascular disease patients on aspirin therapy (75--100 mg/d,≥l month) were divided into AR group (n=59) and non-AR group (n=372) according to the AR di- agnostic criteria. P2Y1 rs5853517 (893C〉T) and P2Y12 rs5853517 (i-insS01A,H1/H2 haplotype) were identified using the SNP genotyping technique of US Sequenom System. Results The serum creatinine level was significantly higher in AR group than in non-AR group (92. 82 ± 83. 07 μmol/L vs 78.75±20.41 Ixmol/L,P〈0.01). No significant difference was found in the frequency distribution of mutant T allele in P2Yt rs1065776 (893C〉T), mutant T allele TT+CT genotype and wild CC, P2Ylz H1/H2 and mutant H2 haplotype, H2/H2 +H2/H1 genotype and wild H1/H1 between the two groups (P〉0.05). Conclusion AR is not related with platelet ADP receptor P2Y1 and P2YI2 gene polymorphism in elderly Chinese patients with cardio-cerebrovascular disease.
