摘要: 目的 探讨电针治疗阿尔茨海默病的效果和作用机制。
方法 雄性8月龄APP/PS1小鼠24只随机分为模型组、电针组和非穴组,各8只。8只野生型小鼠为野生组。电针组电针百会、神庭,非穴组电针双侧肋下非穴区,野生组和模型组予相同抓取和固定,共28 d。干预后,Morris水迷宫测试小鼠学习记忆能力,分别采用免疫荧光和免疫组化技术检测小鼠大脑皮质β淀粉样蛋白(Aβ)和β位淀粉样前体蛋白裂解酶1 (BACE1)含量,RT-PCR检测BACE1 mRNA水平。
结果 与模型组比较,电针组小鼠Morris水迷宫逃避潜伏期显著下降(P < 0.001),穿越平台次数显著增加(P < 0.001),BACE1表达和Aβ水平显著减少(P < 0.001)。
结论 电针百会、神庭可能通过抑制APP/PS1小鼠大脑皮质BACE1表达,降低Aβ水平,改善小鼠学习记忆能力。

Abstract: Objective To explore the effects of electroacupuncture at Baihui (DU20) and Shenting (GV24) on Alzheimer's disease, and possible mechanism for it.
Methods A total of 24 eight-month-old APP/PS1 male mice were randomly divided into model group (n = 8), electroacupuncture group (n = 8) and non-acupoint group (n = 8), and other eight wild-type mice were as wild-type group. The electroacupuncture group accepted electroacupuncture at Baihui and Shenting, while the non-acupoint group accepted electroacupuncture at bilateral subcostal non-acupoint area, and the wild-type group and the model group accepted the same grasping and fixing, for 28 days. Then they assessed with Morris water maze test. The levels of β-amyloid protein (Aβ) and β-site amyloid precursor protein cleaving enzyme 1 (BACE1) in cerebral cortex were detected with immunohistochemistry and immunofluorescence respectively, and the level of BACE1 mRNA with RT-PCR.
Results Compared with the model group, the escape latency decreased in the electroacupuncture group (P < 0.001), and the times crossing platforms increased (P < 0.001), while the expression of BACE1 and Aβ decreased (P < 0.001).
Conclusion Electroacupuncture may improve the learning-memory ability by inhibiting the expression of BACE1 in the cerebral cortex of APP/PS1 mice to decreasing the level of Aβ.
