中文摘要:
      目的: 外伤性脑梗死(posttraumatic cerebral infarction, PTCI)是颅脑损伤的常见并发症之一, P2Y12 受体介导血小板聚集是血 栓形成的重要通路,与 血小板聚集形成密切相关。本研究探讨外伤性脑梗死发生发展与 血小板膜 P2Y12 受体基因 T744C 基因 多 态性的关系。 方法: 用 聚合酶链反应(PCR)和限制性酶切片 段长度多态性(RFLP)技术对 1 86 例外伤性脑梗死患者 P2Y12 受体基因 T744C 多态性进行分析。 分别在治疗前和治疗后对所有颅脑外伤患者的伤情 GCS 评分,并按基因 型分组对照分析结果。 结果: 血 小板膜 T744C 血小板膜 T744C 基因 型基因 频率分别为 TT 基因 型 59.14%、 TC 型 32.26%、CC 型 8.60%, T 等位基因 75.27%、 C 等 位基因 24.73%; 其中 TT 基因 型对奥扎格雷反应较敏感, GCS 评分预后好;而 CC 型对奥扎格雷反应性低, 预后差。 结论: T744C 基因 多态性中 CC 基因 型可能导致外伤性脑梗死临床及预后存在明显的个体差异,与 其对抗血小板药物抵抗有关。 T744C 的 C 等位基因可能是脑梗死的遗传危险因 素, 开展相关遗传学风险研究, 对于进一步缓解脑梗症状、改善预后具有重要意义。
英文摘要:
      Objective:Traumatic cerebral infarction (PTCI) is a common complication of traumatic brain injury, which is closely related to platelet aggregation. The aim of this study was to evaluate the effect of polymorphisms affecting the P2Y12 receptor (P2Y12 T744C) on modulating platelet function in acute PTCI patients on regular treatment. P2Y12 receptor-mediated platelet aggregation is an important pathway for thrombosis. This article explores the traumatic cerebral infarction film development and platelet P2Y12 receptor gene T744C gene polymorphism relationship.Methods:GCS score evaluating the cure effect of PTCI patients. PCR-RFLP analysis of 186 cases of P2Y1 2 receptor gene T744C polymorphism.Results:The platelet membrane T744C genotype gene frequencies 59.1 4% of the TT genotype, TC 32.26% CC 8.60%, the T alleles 75.27% and C alleles 24.73%. Among people with TT genotype, the GCS score and prognosis are better than CC group. What's more, the CC genotype reduces the ability of ozagrel to inhibit platelet aggregation.Conclusion:T744C gene polymorphism CC genotype is a high risk of the disease. T744C C allele may be a genetic risk factor of cerebral infarction. More studies are needed to determine the possible interaction between the genetics factors, platelet response to ozagrel and long term prognosis.
