[摘要] 缺血性脑卒中致残率、致死率一直居高不下且严重危害我国人民健康。脑内侧支循环的形成和建立,对缺血性脑卒中的发生、发展、治疗与预后有很重要的影响。想要制定一个很好的后续治疗方案和判断卒中预后的关键在于如何早期预测脑内侧支循环或血管新生状况。目前有TCD、CTA、MRA、MRP、DSA等方法可以用于评价侧支循環好坏,但上述检查各具优缺点,如昂贵、耗时、分辨率低、有创伤、或受医疗条件限制等诸多因素影响,存在很多局限性,不能在实际临床工作中广泛应用。因此,迫切需要找出一种能具有特异性、早期、无创、简单等特点预测脑内侧支循环状况的生物学标记物,用于指导卒中的治疗及判断预后。MIR-l26是血管新生信号通路中的正调节因子,近年研究表明血清MIR-126水平与脑侧支循环形成呈显著正相关,可能成为判别脑侧支循环形成情况的一种血液标志物。现对血清miRNAs(MIR-126)与脑侧枝循环的相关性综述如下。

[Abstract] The disability rate and morbidity of cerebral arterial thrombosis is still high, seriously threatening peoples health in China, and the formation and establishment of cerebral collateral circulation has an important effect on the occurrence, development, treatment and prognosis of cerebral arterial thrombosis, and the key of making a best subsequent treatment plan and determining the prognosis of stroke is to predict the cerebral collateral circulation or angiogenesis in the early stage, currently, the TCD, CTA, MRA, MRP, DSA can be used in evaluating the quality of collateral circulation, but the above examination has its advantages and disadvantages, limited by the high price, time-consuming, low resolution, wound, medical conditions, and failing to be widely used in practical clinical work, therefore, it is urgent to find out the biology markers to guide the stroke treatment and determining the prognosis, and the MIR-l26 is the positive regulation factor in the angiogenic signal pathway, and the recent study shows that the serum MIR-126 level is positively correlated with the cerebral collateral circulation, which may be a kind of blood marker of determining the cerebral collateral circulation, and the paper elaborates the correlation between the cerebral collateral circulation and serum miRNAs(MIR-126)as follows.

缺血性卒中与脑侧支循环密切相,脑侧支循环的好坏与缺血性卒中治疗及预后密切相关,侧支循环是指通过改变血流路径而起到对闭塞血管供血区提供逆向血流灌注的作用。目前很多冠脉血管研究发现很多血液标记物与冠脉侧支循循环相关。其中MIR-126为其中一种很重要的血液标记物,为目前研究的热点与难点,部分研究显示MIR-126与脑侧支循环存在相关性,但其作用机制尚不明确。……
