摘要
目的探讨缺血后适应对脑缺血大鼠再灌注损伤(IRI)的S-100B蛋白、超敏感性C反应蛋白含量表达的影响,比较在不同时间位点的作用特点。方法采用线栓法制作大鼠动脉缺血再灌注动物模型。Wistar大鼠随机分为6组:假手术组(Sham组),IRI组,缺血后适应(IP)Ⅰ~Ⅳ组。检测脑损伤标志物S-100B蛋白、超敏感性C反应蛋白(h-CRP)含量变化。结果与IRI组比较,IPⅠ~Ⅳ各组大鼠神经功能缺损评分、S-100B及C反应蛋白(h-CRP)显著降低,且IPⅠ~Ⅳ各组依次递增,数据均有统计学意义。结论缺血后适应可改善大鼠术后神经功能缺损评分,下调S-100B蛋白、超敏感性C反应蛋白含量表达,对局灶性脑缺血再灌注损伤大鼠具有保护作用。
Objective To investigate adaptation ischemic cerebral ischemia- eperfusion injury (ischemia reperfusion injury, IRI) of S-100B protein, ultra- sensitivity C-reactive protein expression comparison sites in different time characteristics. Methods Using suture method cerebral artery occlusion and reperfusion animal model. Wistar rats were randomly divided into six groups: sham operation group (Sham group), IRI group, ischemic postconditioning (ischemia postconditioning, IP) I - IV group. Content change of S- 100B protein and super sensitive C reactive protein (h-CRP) in brain injury markers. Results Compared with the IRI group, the neurological deficits score, S-100B and C reactive protein (h-CRP) were significantly decreased in all groups, and the IP I-IV groups were increased in turn. The data were statistically significant. Conclusion After ischemia adaptation can improve the postoperative rats neural function defect score and down regulation of S-100B protein, hypersensitive C reaction protein expression, after focal cerebral ischemia reperfusion injury in rats has a protective effect.
