急性缺血性脑卒中具有发病率、致残率、复发率、死亡率均较高的特点。目前,诊断急性缺血性脑卒中主要依靠影像学检查结果,如CT和MRI。近年来,关于缺血性脑卒中生物标志物的研究表明,检测血生物标志物可提高缺血性脑卒中患者诊断的准确率和及时性[1-3]。胶质纤维酸性蛋白(glial fibrillary acidic protein,GFAP)最初从慢性多发性硬化症患者的白质斑块中发现,被认为是星形胶质细胞的成熟 Acute ischemic stroke with morbidity, morbidity, recurrence rate, mortality were higher characteristics. Currently, diagnosis of acute ischemic stroke relies mainly on imaging findings such as CT and MRI. In recent years, studies on biomarkers of ischemic stroke have shown that the detection of blood biomarkers can improve the diagnostic accuracy and timeliness of patients with ischemic stroke [1-3]. Glial fibrillary acidic protein (GFAP) was originally found in white matter plaque in patients with chronic multiple sclerosis and is considered as mature astrocytes
