摘要 目的通过观察头穴丛刺法对慢性脑缺血大鼠学习记忆能力和HIF-1α表达的影响,探讨头穴丛刺治疗慢性脑缺血的作用机制。方法 26只大鼠采用改良的双侧颈总动脉永久性结扎法(2VO)制备慢性脑缺血模型,造模成功的大鼠分为假手术组(A组)、模型组(B组)和头穴丛刺组(C组)。C组采用头穴丛刺法,A组和B组不予治疗。术后8周采用Morris水迷宫检测大鼠学习记忆能力;免疫组化法检测额叶皮层、海马HIF-1α蛋白表达。结果术后8周B组和C组逃避潜伏期和游泳路程均明显延长,跨越平台次数明显减少,与A组相比具有显著性差异(P<0.05);但C组与B组相比,逃避潜伏期和游泳路程明显缩短,跨越平台次数增加,差异显著(P<0.05)。免疫组化A组偶见HIF-1α阳性细胞表达,B组和C组均可见HIF-1α表达增高,与A组比较差异显著(P<0.05);C组较B组表达升高,差异显著(P<0.05)。结论头穴丛刺能够明显改善大鼠的学习记忆功能,其可能通过促进HIF-1α表达来提高大鼠的学习记忆能力。
