摘　　要：缺血性脑损伤在脑损伤中占87%,常导致严重的功能障碍。多巴胺是大脑内含量最丰富的儿茶酚胺类神经递质,与自主运动、情感、睡眠、认知等功能密切相关。缺血性脑损伤后患者脑内多巴胺功能严重失调。有研究发现多巴胺受体激动剂如罗匹尼罗、普拉克索、吡贝地尔等可通过受体或非受体依赖途径减轻脑损伤,对学习、记忆、行为、意识等功能有明显改善。本文就不同多巴胺受体激动剂在缺血性脑损伤的脑保护方面可能的作用机制进行综述。Ischemic brain injury comprises 87%of all brain injuries and typically results in severe functional impairments.Dopamine,the most abundant catecholamine neurotransmitter in the brain,is intimately linked with autonomous movement,emotion,sleep,cognition,and other critical functions.Following ischemic brain injury,patients have severe dysfunction of dopamine in the brain.Studies have demonstrated that dopamine receptor agonists,such as ropinirole,pramipexole,and piribedil,can mitigate brain injury through both receptor-dependent and non-receptor-dependent pathways.These agonists have significant improvements in functions including learning,memory,behavior,and consciousness.This article reviews the potential mechanisms of various dopamine receptor agonists in brain protection after ischemic brain injury.
