SCI REP:端粒磨损与首次脑卒中的关系!

由此可见,该研究提供的数据表明白细胞端粒与动脉粥样硬化性卒中、腔隙性脑梗死独立相关。

端粒长度与脑卒中之间的关系不一致,主要是由于亚型、环境和遗传学的发病机制不同所致。近日,Scientific reports 杂志上发表了一篇研究文章,研究人员旨在评估白细胞端粒是否会促进卒中的发生。

研究人员通过调查包含了543例病例(224例动脉粥样硬化性脑卒中患者,94例出血性卒中患者和225例腔隙性脑梗死患者)和616例对照者的病例对照研究,并且在一个独立包括相同诊断标准的773例病例和875例对照者组成的研究中进行重复。

研究人员发现正常对照者(相关系数γ =-0.28,P<0.001)和动脉粥样硬化性脑卒中病例(γ=-0.17,P=0.012)中端粒与增长的年龄呈负相关。在端粒长度处于最低三分位数的个体表现出动脉硬化性脑卒中风险较高[比值比为2.33,95%可信区间(CI)为1.42-3.83;P=0.003],而腔隙性脑梗死患病率较低(比值比为0.49,95%CI为0.30-0.81;P=0.007)。在第二次重复研究中也获得了相似的结果。进一步的meta分析显示,较短的端粒与缺血性卒中的风险增加12%相关(95%CI为1.04-1.18),但根据研究设计和种族划分时在回顾性研究和亚洲人群中,这种关联更强。

由此可见,该研究提供的数据表明白细胞端粒与动脉粥样硬化性卒中、腔隙性脑梗死独立相关。
