C-反应蛋白水平对急性缺血性脑卒中预后影响的系统评价

目的 应用Meta分析,评价C-反应蛋白(C-reactive protein,CRP)水平对急性缺血性脑卒中预后的影响.方法 计算机检索PubMed、MEDLINE(1991-2006)、中国学术期刊全文数据库(1979-2006)等.搜集CRP水平对急性缺血性脑卒中预后影响非随机对照研究,逐篇评价纳入文献的质量,采用RevMan4.2版软件进行Meta分析.结果 共纳入7篇文献(外文4篇,中文3篇),涉及841例患者.在急性缺血性脑卒中患者中,3个月以上随访截尾时间的死亡率和再发血管事件与CRP水平相关,CRP增高组发生率比CRP正常组分别高2.71和1.81倍[OR合并分别为3.71和2.81,95%CI分别为(2.40,5.73)和(1.42,5.53)]均有统计学意义(P＜0.05);CRP测量值与缺血性脑卒中复发和死亡亦相关,在复发患者中,CRP测量值平均高于未复发者为3.52 mg/L[WMD=3.52,95%CI(-0.01,7.05)],具有一定的临床意义;在死亡患者中,CRP测量值平均高于生存者为8.02 mg/L[WMD=8.02,95%CI(5.68,10.37)],具有统计学意义(P＜0.05).结论 发病时CRP的水平可以初步评价急性缺血性脑卒中患者的预后.     

Ischemia independent lesion evolution during focal stroke in rats

Lesion evolution during focal cerebral ischemia may depend on flow restrictions or on accumulation of toxic mediators within the infarct and expansion of these factors to the periinfarct region. So far, the precise contribution of flow dependent versus spreading-mediated impairment of viable periinfarct tissue has not been determined. Therefore, we measured lesion expansion, flow restrictions and glutamate distribution on serial brain sections at different time points after experimental focal ischemia.Permanent focal ischemia was induced by occlusion of the right middle cerebral artery in male rats and the flow reduction was subsequently measured at 1, 12 and 24 h using iodo[¹⁴C]antipyrine autoradiography. Additionally, the necrotic volume was determined on serial brain sections and the glutamate content was measured in tissue samples from adjacent microdissections.Twelve hours after focal ischemia no noteworthy viable areas with blood flow restrictions of 20-40 ml 100 g^− 1 min^− 1 existed but at 24 h the necrotic tissue exceeded the hemodynamically compromised region by 40 ± 21 mm³ (24%). Furthermore, at 12 and 24 h the glutamate content was elevated in areas surrounding the infarct.Relevant flow restrictions are detectable only during early stages of infarct maturation, whereas the propagation of secondary factors may be the predominant mechanism for delayed infarct evolution.     

The association of post-stroke neurological improvement with risk of subsequent deterioration due to stroke events

We sought to simultaneously confirm that substantial recovery at day 1 and day 7 after acute ischaemic stroke onset is associated with subsequent neurological deterioration in patients of the Acute Stroke Therapy by Inhibition of Neutrophils randomized clinical trial. Substantial recovery was assessed by improvement in the National Institutes of Health Stroke Score (NIHSS). Neurological deterioration was defined as any stroke event or NIHSS worsening from recovery assessment to day 90. After adjusting for age, t-PA and day 1 NIHSS, there was a non-significant tendency of substantial (pre-specified as 75%) recovery at day 1 to be associated with later deterioration [odds ratio (OR) 2.47; 95% CI, 0.95–6.50]. The corresponding OR for substantial (pre-defined as 65%) recovery at day 7 was 1.84 (0.85–3.96). Other thresholds for recovery were significantly associated with later deterioration: >50%, 80%, 90% and 100% for day 1 and >50%, 60%, 70%, 90% and 100% for day 7. The effect of recovery at day 1 was more important than that of later recovery. This study confirms the association between recovery and subsequent neurological deterioration and is the first to indicate the greater importance of acute recovery at day 1 in comparison with later recovery.     

Alberta早期CT评分的临床应用

超早期溶栓被公认为脑血栓形成最有效的治疗手段，但是，什么样的患者最适合溶栓治疗，目前还没有一种公认的标准。有学者提出用一种基于CT早期缺血性改变的半定量方法——Alberta早期CT评分（ASPECTS）来选择适合溶栓治疗的患者。ASPECTS是一种仅适用于评价大脑中动脉（MCA）供血区缺血改变的量表，其总分为10分。ASPECTS=10分提示MCA供血区无早期缺血征象，ASPECTS=0分表示MCA供血区广泛缺血，提示MCA主干闭塞。多数学者认为，ASPECTS〉7分的患者是溶栓治疗的最佳候选者，而当ASPECTS≤7分时，溶栓治疗不但不能改善症状，反而会增高颅内出血的风险。然而，对ASPECTS的溶栓治疗选择标准仍然存在一些不同的看法，文章就ASPECTS的具体操作及其在临床实践中的应用进行了综述。
