ABCD2量表在短暂性脑缺血发作预后评估中的作用

部分短暂性脑缺血发作(transient ischemic attack,TIA)患者可能会进展为缺血性卒中,部分患者因合并心血管病而死亡.近年来的研究显示,ABCD2量表在TIA预后评估中有着重要价值.文章概述了ABCD2量表的来源和应用,重点阐述了该量表在TIA预后评估中的作用.     

急性期脑梗死患者血清MMP-9水平动态变化意义及与预后的关系

目的 通过对急性脑梗死患者不同时间点血清基质金属蛋白酶-9(Matrix Metalloproteinase,MMP-9)的测定和比较,探讨MMP-9水平与脑梗死TOAST分型及预后的关系.方法 收集急性脑梗死患者60例,对照组20例,分别测定急性脑梗死患者发病24h内、第5天和第10天的血清MMP-9含量,记录患者入院时的美国国立卫生研究所中风量表(NIHSS)评分;随访6个月,记录发病1个月时和发病6个月时的BI(Baahal Index)来评价预后.结果 (1)发病后24h内,脑梗死组TOAST各亚型血清MMP-9含量均升高,与对照组比较差异具有显著性(P<0.05),其中,CE组和LAA组MMP-9含量持续至第5天仍未下降,而SA组已逐渐降至正常水平;第10天各组MMP-9含量均降至正常水平.(2)发病后24h内血清MMP-9含量与相应时段NIHSS评分具有直线相关关系(r=0.883,P<0.01).(3)预后较好组其发病24h内血清MMP-9含量明显低于预后较差组(P<0.05).结论 (1)脑梗死后各组血清MMP-9的含量升高,但它们的变化趋势不尽相同.(2)发病后24h内MMP-9含量与与病情的严重程度有关.(3)脑梗死后24h内的血清MMP-9含量是预后的独立预测因素.

Abstract：

Objective To determine and compare the level of serum MMP-9 at acute stage of cerebral infarction and to approach the relationship among the level of serum MMP-9 and the classification of TOAST and the significance in prognosis. Methods 60 patients with cerebral infarction were included in our study,while 20 healthy people served as the control group. The serum specimens were gathered for MMP-9 determination with ELISA on admission, at the 5th and 10th day of onset. All patients were scored according to the American National Institutes of Health stroke scale ( NIHSS) on admission and recorded Barthal Index(BI) in the 1st and 6 month of onset. Results (1)The serum level of MMP-9 increased after cerebral infarction,and was significantly higher than those in the control group(P <0. 05). There was no significant difference between CE and LAA group ( P>0. 05). MMP-9 in CE and LAA group was significantly higher than those in SA group (P <0. 05) . MMP-9 in SA group decreased to normal level while was still higher in CE and LAA group on the 5th day of onset. On the 10th day MMP-9 in all groups decreased to normal. (2) There was a positive correlation between MMP-9 within 24 hours of onset and NIHSS( r = 0. 883 ,P < 0. 01) . (3) The serum level of MMP-9 in the cases with better prognosis was significantly lower than those with worse prognosis. Conclusions (1) The serum levels of MMP-9 in all groups increased, but the tendency of their variation was not similar;( 2 ) Serum level of MMP-9 was related to NIHSS, can reflect the severity of the state of cerebral the severity of the state of cerebral infarction;( 3 ) The level of serum MMP-9 within 24 hours of onset can predict prognosis of cerebral infarction independently.     

椎动脉狭窄CT血管造影与数字减影血管造影的对比研究

短暂性脑缺血发作(TIA)是一种短暂的伴有局部症状的脑循环障碍征候群。临床上根据受累血管分为颈内动脉及椎-基底动脉TIA两大类。频发TIA是指24h内TIA发作≥2次的特殊临床状态[1]。椎-基底动脉频发TIA起病急、症状重,若栓塞引起的TIA可能危及生命,其病因复杂,部分病例与椎-基底动脉狭窄有关。椎动脉狭窄的诊断以往主要依赖于数字减影血管造影(DSA)。近年来,CT血管造影(CTA)被广泛应用于临床,取得了令人瞩目的进展。我们对20例频发TIA患者进行DSA及CTA对照研究,探讨CTA对椎-基底动脉频发TIA的诊断价值。1对象与方法1.1对象…     

脑梗死后脑水肿的研究进展

<正>关于恶性脑梗死,国内外尚未形成统一的命名和定义。早在1996年,Hacke首次提出"恶性大脑中动脉梗死"一词。大面积脑梗死的概念,一般是指由于颈内动脉远端和大脑中动脉(MCA)近端闭塞导致的大部分MCA供血区的脑梗死,也可同时累及大脑前动脉或大脑后动脉供血区。恶性脑梗死能引起临床恶化和脑水肿形成,还与出血性转化、脑疝形成有关,病死率高达80%,又被称为恶性水肿。因此,恶性     

胰岛素样生长因子-1对大鼠血肿周围缺氧诱导因子及脑水肿动态观察的影响

目的研究重组人胰岛素样生长因子(rhIGF-1)对大鼠血肿周围缺氧诱导因子(hypoxia inducible factor-1α,HIF-1α)在21d内变化的影响。方法采用自体鼠尾血脑内注射法建立动物模型,动物的实验脑出血模型,应用免疫组化方法检测脑出血后的HIF-1α蛋白表达情况,并应用干湿比重法测定脑组织含水量。结果出血后,HIF-1α蛋白阳性表达率随时间逐渐增加,72h达高点,此后逐渐下降,脑出血后各时间点阳性率比较差异有统计学意义(P<0.05),脑出血IGF-1干预组较脑出血组及假手术组各时间点脑组织含水量低,HIF-1α蛋白阳性率较低。结论胰岛素样生长因子能显著降低HIF-1α表达,对脑出血后脑组织有良好的保护作用。
