| 中文摘要: |
| 蛛网膜下腔出血(SAH)是神经系统的急危重症,常有不良预后。临床研究发现早期脑损伤(EBI)广泛存在于SAH患者中,可能是造成预后不良的重要原因。临床前研究在了解EBI的机制方面取得了进展,小胶质细胞是参与EBI的主要细胞成分。EBI中的神经炎症主要由M1型小胶质细胞驱动,参与血脑屏障破坏和神经元死亡；此外,M2表型小胶质细胞表现出减轻脑水肿和改善神经功损伤的功能。因此,阐明SAH后小胶质细胞的极化及参与EBI的途径对干预SAH神经炎症反应具有重要意义。 |
| 英文摘要: |
| Subarachnoid hemorrhage (SAH) is a neurological emergency and often carries a poor prognosis. Clinical studies have found that early brain injury (EBI) is widespread in patients with SAH and may be an important cause of poor prognosis. Preclinical studies have made progress in understanding the mechanisms of EBI, and microglia are the major cellular components involved in EBI. Neuroinflammation in EBI is mainly driven by M1 phenotype microglia, which are involved in blood-brain barrier disruption and neuronal death; in addition, M2 phenotype microglia exhibit functions in reducing cerebral edema and ameliorating neurological work injury. Therefore, elucidating the polarization in microglia and the pathways affecting EBI after SAH is important for its intervention in the neuroinflammatory response to SAH. |
