摘　　要：目的动态观察急性脑梗死患者血清白介素-1β(Interleukin-1β,IL-1β)、C-反应蛋白(C-reactive protein CRP)含量变化,探讨炎症因子在脑梗死发病机制中的作用。方法抽取33例急性脑梗死患者发病3d内、7d和14d时的空腹静脉血,采用双抗体夹心酶联免疫吸附法(enzyme-linkedimmunosorbent assay,ELISA)测定血清IL-1β的水平,免疫速率散射比浊法测定血清CRP水平,并与30名健康对照组比较。结果急性脑梗死患者发病3d内、7d和14d时血清IL-1β、CRP水平均显著高于正常对照组(P<0.05),其中发病3d内水平最高,随时间推移及治疗的介入,炎症因子水平逐渐下降;3d内测定的不同梗死体积患者血清IL-1β、CRP含量存在显著性差异(P<0.05);直线相关分析表明二者之间存在正相关。结论急性脑梗死患者血清IL-1β、CRP水平明显升高,并与急性脑梗死的体积密切相关,对炎症反应的干预治疗可能有利于减轻缺血性脑损害。Objective To explore the role of IL- 1β and CRP in the pathogenesis of acute cerebral infarction. Methods Study included 33 patients with acute cerebral infarction and 30 healthy people as control. Serum IL-1β was measured by enzyme-linked immunosorbent assay （ELISA）, and serum CRP was detected by the immune rate nephelometry. Results Compared with control group, the serum levels of IL-1β and CRP within 3 days, on the 7th day and 14th day in patients with acute cerebral infarction were increased significantly （ P 〈 0.05）, with the levels within 3 days were the highest in patients with acute cerebral infarction. There was a positive correlation between the increasing degree of serum levels of IL-1β and CRP and the size of infarct area （ P 〈 0.05）. Conclusions Serum IL-1β and CRP are increased significantly in patients with acute cerebral infarction, they possibly play a key role in the pathogenesis of acute cerebral infarction, therefore anti-inflammatory drugs maybe will become potential new therapeutic agents for acute cerebral infarction.
