目的：观察乌司他丁对颅内动脉瘤栓塞手术患者促炎性细胞因子的影响。方法：选择颅内动脉瘤栓塞手术患者40例，随机分为乌司他丁组（U组，n ＝20）和对照组（C组，n ＝20）。 U组在麻醉诱导前予乌司他丁6000 IU／kg；C组予等量生理盐水，分别于T1、T2、T3、T4、T55个时点抽取动脉血，测定血清TNF-α和IL-6水平。结果：两组患者血清TNF-α在T3、T4、T5与T1比较均明显升高（P ＜0．05），但U 组血清TNF-α在T3、T4、T5时点升高不如C组明显（P ＜0．05）；两组患者血清IL-6水平在T3、T4、T5与 T1比较均明显升高（P ＜0．05），但U组血清IL-6在T3、T4、T5时点升高不如C组明显（P ＜0．05）。结论：乌司他丁能抑制颅内动脉瘤栓塞手术后促炎性细胞因子的释放，减轻炎症反应介导的脑缺血再灌注损伤，对颅内动脉瘤栓塞手术患者具有一定的脑保护作用。%Objective To explore the effect of Ulinastatin on proinflammatory cytokines of patients undergoing operation of intracranial aneurysm embolization. Methods 40 patients undergoing operation of intracranial aneurysm embolization were randomly divided into 2 groups (n = 20): ulinastatin group (Group U), normal saline group (Group C). In group U, 6 000 IU/kg Ulinastatin was infused via vein before anesthesia induction, the group C received the injection of isovolume normal saline. Exsanguinated arterial blood at T1, T2, T3, T4 and T5 five time points were taken to measure TNF-α and IL-6 in serum. Results The contents of TNF-α and IL-6 in serum both increased at T3, T4 and T5 compared to that at T1 in both groups; both TNF-α and IL-6 significantly decreased in Group U compared to that in Group C at the same time point. Conclusion Ulinastatin may inhibit the release of inflammatory mediators and lighten cerebral ischemia-reperfusion injury in patients undergoing operation of intracranial aneurysm embolization.
