缺血性脑卒中是临床常见脑血管疾病,具有高发病率、高致残率及高病死率等临床特征。临床治疗缺血性脑卒中方法多样,其中溶栓治疗可有效改善缺血组织,恢复缺血半暗带生理功能,但受溶栓时间窗限制较为严重,且易引发颅内出血或再灌注损伤等多种严重并发症,对疗效及转归产生不利影响。硒是人体必需的一种微量元素,适量补硒可增强机体免疫力,维持肺、心等重要脏器功能,预防心脑血管等疾病发生。本文探究补硒治疗对缺血性脑卒中患者抗氧化能力的影响。 Ischemic stroke is a common clinical cerebrovascular disease, with high morbidity, high morbidity and high mortality and other clinical features. Clinical treatment of ischemic stroke varied, including thrombolytic therapy can effectively improve the ischemic tissue and restore the physiological function of the ischemic penumbra, but by the thrombolytic time window is more serious, and can easily lead to intracranial hemorrhage or reperfusion injury A variety of serious complications, adverse effects on outcome and outcome. Selenium is a trace element essential to the human body, appropriate amount of selenium can enhance immunity, maintain lung, heart and other vital organs function, prevention of cardiovascular and cerebrovascular diseases.
