摘要： 目的探讨头穴丛刺结合丰富环境刺激对缺氧缺血性脑损伤(HIBD)新生大鼠内源性神经干细胞(NSCs)增殖及迁移的影响。方法用Rice法建立HIBD动物模型，随机分为假手术组、造模组、头穴丛刺组、丰富环境刺激组和头穴丛刺结合丰富环境刺激组，每组24只，每组又分为3d、7d、14d。应用免疫组化法观察5-溴脱氧尿核苷(BrdU)和巢蛋白(nestin)阳性细胞数。结果与造模组同期比较，3d、7d、14d头穴丛刺组、丰富环境刺激组侧脑室下区(SVZ)和大脑皮层BrdU、nestin阳性细胞数明显增加(P<0.01)；头穴丛刺结合丰富环境刺激组BrdU、nestin阳性细胞数高于同期头穴丛刺组和丰富环境刺激组(P<0.05)。结论头穴丛刺结合丰富环境刺激可促进HIBD新生大鼠SVZ和大脑皮层区内源性NSCs的增殖迁移。
