目的：明确白细胞在急性脑卒中发病中的作用及其对急性脑卒中患者近期预后的影响。方法：对98例脑梗死，60例脑出血，32例蛛网膜下腔出血及60名健康对照组周围血白细胞数进行检测，同时将患者分成高白细胞组和正常白细胞组，以患者在起病后1月内生存或死亡作为判断预后指标。结果：急性脑卒中患者早期白细胞数较对照组增高，高白细胞细死亡率明显高于正常白细胞组，白细胞数增高与脑损伤严重程度及早期预后有关。结论：白细胞数增高可能在急性脑卒中发病中发挥作用，还影响到患者近期预后。 Objective: To clarify the role of leukocytes in the pathogenesis of acute stroke and its effect on the prognosis of patients with acute stroke. Methods: 98 cases of cerebral infarction, 60 cases of cerebral hemorrhage, 32 cases of subarachnoid hemorrhage and 60 healthy control group were detected the number of white blood cells, while the patients were divided into high white blood cells and normal white blood cells, patients with onset After 1 month survival or death as a prognostic indicator. Results: The number of early white blood cells in acute stroke patients was higher than that in control group. The mortality of high white blood cells was significantly higher than that of normal white blood cells. The increase of white blood cell count was related to the severity of brain injury and early prognosis. Conclusion: Increased white blood cell count may play a role in the pathogenesis of acute stroke and also affect the recent prognosis of patients.
