摘要:

目的 观察电针百会、神庭对血管性认知障碍(VCI)大鼠脑区功能活动和工作记忆的影响。方法 18只Sprague-Dawley大鼠,其中12只结扎双侧颈总动脉造模,假手术组6只不结扎。造模大鼠随机分为模型组(n = 6)和电针组(n = 6),电针组电针百会和神庭,共4周。干预前后采用Y迷宫、Morris水迷宫进行评定;干预后行静息态功能磁共振成像扫描,计算局部一致性(ReHo)。结果 干预前,与假手术组相比,模型组和电针组Y迷宫交替率显著降低(P < 0.001),Morris水迷宫逃避潜伏期升高(P < 0.05);干预后,电针组Y迷宫交替率较模型组增高(P < 0.05),Morris水迷宫工作记忆逃避潜伏期降低(P < 0.05)。与假手术组相比,模型组双侧海马、嗅觉皮质、感觉皮质、听觉皮质,左侧纹状体ReHo降低;与模型组相比,电针组双侧前额叶、海马、嗅觉皮质,左侧杏仁核ReHo升高。结论 电针百会、神庭可改善VCI大鼠工作记忆,可能与调节前额叶、海马、杏仁核等脑区功能活动有关。

Abstract:

Objective To observe the effect of electroacupuncture at Baihui (DU20) and Shenting (DU24) on brain functional activity and working memory of rats with vascular cognitive impairment (VCI). Methods Eighteen Sprague-Dawley rats were included, in which twelve rats were ligated bilateral common carotid arteries and six rats were not ligated (sham group). The modeled rats were randomly divided into model group (n = 6) and electroacupuncture group (n = 6). The electroacupuncture group received electroacupuncture at Baihui and Shenting for four weeks. They were assessed with Y maze and Morris water maze before and after intervention, and scaned with resting-state functional magnetic resonance imaging after intervention to calculate regional homogeneity (ReHo). Results Compared with the sham group, alternation rate of Y maze decreased (P < 0.001), and escape latency of Morris water maze increased (P < 0.05) in the model group and the electroacupuncture group before intervention. Compared with the model group, alternation rate of Y maze increased (P < 0.05), and escape latency of Morris water maze decreased (P < 0.05) after intervention in the electroacupuncture group. Compared with the sham group, ReHo of bilateral hippocampus, olfactory cortex, sensory cortex and auditory cortex, and left striatum decreased in the model group; compared with the model group, ReHo of bilateral prefrontal lobe, hippocampus and olfactory cortex, and left amygdala increased in the electroacupuncture group. Conclusion Electroacupuncture at Baihui and Shenting can improve the memory function of VCI rats, which may be related to the functional activities of prefrontal lobes, hippocampus and amygdala.
