目的
2
观察电针“百会”“涌泉”对APP/PS1双转基因小鼠学习记忆能力、海马区β淀粉样蛋白沉积及相关蛋白表达的影响,从内体-溶酶体系统角度探讨电针改善阿尔茨海默病(AD)的作用机制。
方法
2
将6月龄雄性APP/PS1转基因小鼠随机分为模型组和电针组,每组10只;另以10只6月龄雄性C57BL/6小鼠作为正常组。电针组针刺“百会”“涌泉”,双侧“涌泉”接电针,15 min/次;模型组和正常组在相同时间以相同方法束缚15 min/次。以上干预均隔日1次,共6周。以Morris水迷宫实验检测各组小鼠学习记忆能力,免疫组织化学法检测小鼠海马区老年斑(SP)的阳性表达,透射电镜观察小鼠海马神经元内体、溶酶体超微结构,Western blot法检测小鼠海马Ras相关蛋白5(Rab5)、Ras相关蛋白7(Rab7)、组织蛋白酶D(CTSD)等内体-溶酶体系统相关蛋白的表达水平。

0.05,
P
<
0.01),穿越原平台次数及原平台象限游泳路程均减少(

Objective
2
To explore the mechanism of electroacupuncture(EA) in improving learning-memory ability in Alzheimer’s disease (AD) mice from the perspective of endosomal-lysosomal system.
Methods
2
Male APP/PS1 transgenic mice were randomly divided into model group and EA group (
n
=10 in each group) and 10 male C57BL/6 wild mice were taken as the normal group. EA (1 Hz/50 Hz,1 mA) was applied at bilateral “Yongquan”(KI1) and acupuncture was applied at “Baihui” (GV20) for 15 min. The mice of the model and normal groups were subjected to restriction with the same method as those of the EA group for 15 min. The treatment was conducted once every other day for 6 weeks. The spatial learning-memory ability (shown by escape latency of place navigation test and the time of crossing the target platform and total swimming distance in the target quadrant in 1 min of spatial probe test ) was detected by Morris water maze test. The immunoactivity of senile plaques (SP) in the hippocampus tissue was detected by immunohistochemistry. The ultrastructural characters of hippocampal neurons were observed by transmission electron microscope, and the expression levels of Ras-related protein 5 (Rab5), Ras-related protein 7 (Rab7) and cathepsin D (CTSD) in the hippocampus were detected by Western blot, separately.
Results
2
Compared with the normal group, the escape latency, SP immunoactivity, and protein expression levels of Rab5, Rab7 and CTSD were significantly increased (
P
<
0.05,
P
<
0.01), while the number of crossing the original platform and the total swimming distance in the platform quadrant were considerably reduced (
P
<
0.05) in the model group. In contrast to the model group, the EA group had a marked decrease in the escape latency, SP immunoactivity, and protein expression levels of Rab5, Rab7 and CTSD (
P
<
0.05,
P
<
0.01), and a striking increase in the number of crossing the original platform and the swimming distance in the platform quadrant (
P
<
0.05). Results of transmission electron microscope showed an accumulation of endosome, lysosome, and endolysosomes in the hippocampal neurons in the model group, which was evidently milder in the EA group.
Conclusion
2
EA of GV20 and KI1 can improve the learning-memory ability of AD mice, which may be related to its function in reducing hippocampal A
β
deposition and down-regulating endosomal-lysosomal system activity.
