[MMP-9、hs-CRP、BNP、S-100和DD对急性缺血性脑卒中患者预后的影响] S-CRP
[摘要] 目的 观察MMP-9、hs-CRP、BNP、S-100和DD对急性缺血性脑卒中(AIS)患者预后的影响。 方法 选取确诊为AIS的患者53例,检测MMP-9、hs-CRP、BNP、S-100和DD水平并进行随访,采用SAS 9.1.3统计学软件包Kaplan-Meier法进行生存分析,采用Cox回归进行单因素分析和Cox逐步回归进行多因素分析,研究各指标对AIS预后的影响。 结果 单因素Cox回归分析显示,年龄和性别对AIS预后无影响(P > 0.05);多因素Cox逐步回归分析结果显示,MMP-9、hs-CRP、BNP、S-100和DD是AIS预后的危险因素(P < 0.05),尤其是S-100对AIS预后影响最大。 结论 MMP-9、hs-CRP、BNP、S-100和DD与AIS预后密切相关,尤其以S-100影响最为显著。

[Abstract] Objective To observe the influence of MMP-9, hs-CRP, BNP, S-100 and DD on the prognosis of patients with acute ischemic stroke. Methods 53 cases of patients who were diagnosed with AIS were selected. MMP9, hs-CRP, BNP, S -100 and DD levels of patients were detected and all of them were followed up. SAS 9.1.3 software and Kaplan-Meier method were adopted to analyze the survival rate; Cox regression was adopted to carry out univariate analysis and Cox stepwise regression was adopted to carry out multivariate analysis. Then the influence of various indexes in the study on the prognosis of AIS was researched. Results Univariate Cox regression analysis showed that age and gender had no effect on the prognosis of AIS (P < 0.05); multivariate Cox stepwise regression analysis results showed that MMP-9, hs-CRP, BNP, S-100 and DD were the risk factors for the prognosis of AIS (P < 0.05), especially S-100 had the biggest influence on the prognosis of AIS. Conclusion MMP-9, hs-CRP, BNP, S -100 and DD are closely related to the prognosis of AIS, especially of S-100.

急性缺血性脑卒中(acute ischemic stroke,AIS)是一种常见的脑血管疾病,是引起死亡或者残疾的重要原因[1],并且在发展中国家或者医疗资源相对缺乏的地区,该疾病的死亡率和致残率处于上升趋势[2-3]。AIS的诊断和预后的判断主要依赖于影像学检查,但是目前国际上关于AIS生物标志物(biomarker)的研究为临床提供了另外一种可能:从实验室检查的角度快速检测AIS相关的生物标志物,从而对AIS做出及时的诊断。这些标志物主要来自于组织损伤过程释放的小蛋白分子,特别是脑源性的小蛋白分子,其中,不少标志物已经成功应用于其他疾病的辅助诊断,如肌钙蛋白、肌酸激脢(CK-MB)、D-二聚体(D-dimer, DD)和B型利钠肽(B-type natriuretic peptide, BNP)在心肌缺血(myocardial ischemia,MI)、肺动脉栓塞(pulmonary embolism,PE)和充血性心力衰竭(congestive heart failure,CHF)的评估中都起到了重要作用[4]。Reynolds [5]对224 例卒中患者(其中82 例为脑梗死)和214 名健康人血样中的50 种生化指标进行ELISA 检测发现,卒中患者S-100(星形胶质细胞活化标志物)、β-神经营养生长因子、高敏性C反应蛋白(hs-CRP)表达明显高于健康人。相关研究也提示基质金属蛋白酶9(matrix metalloproteinase 9, MMP-9)、 BNP、DD 和S-100在判断急性脑梗死患者的预后上有着特殊的价值[6]。本实验拟在临床水平研究这些生物标志物对AIS预后的影响。
