检索近年国内外老年脑缺血损伤后神经细胞反应的文献资料,回顾老年脑缺血损伤后神经细胞反应的研究进展,发现老年脑缺血损伤后存在神经元细胞反应形式多样和易损性增加,胶质细胞活化增强和胶质瘢痕形成,神经干细胞活性减弱、内环境和微血管受损,以及神经发生能力降低等特点,并从缺血后神经细胞的反应特点探讨细胞修复的可能机制和途径。 Retrieve the literature of nerve cell response in elderly patients with cerebral ischemia at home and abroad in recent years, reviewing the research progress of neural cell response after cerebral ischemia in the elderly, and found that the neuronal response to the changes of the brain is diverse and vulnerable , Activation of glial cells and glial scar formation, decreased activity of neural stem cells, damage to the environment and microvascular, as well as decreased ability of neurogenesis and so on, and explored the possible mechanism and pathway of cell repair from the characteristics of ischemic neuronal response .
