文题释义:
海马体:
又名海马回、海马区、大脑海马,海马体主要负责记忆和学习,日常生活中的短期记忆都储存在海马体中,如果一个记忆片段,比如一个电话号码或者一个人在短时间内被重复提及的话海马体就会将其转存入大脑皮质,成为永久记忆。
电针:电针是针刺疗法中的一种,是电刺激和针刺效应的结合,具有方便快捷、容易定量、可持续刺激等优点,是目前临床治疗缺血性脑血管疾病的常用针刺方法。
脾虚证:中医的脾虚证指机体因脾气不足、失其健运而导致各种外在表现的证候类型,多由饮食不节所致。病理条件下,若脾失健运,气血津液生化不足,则髓海不充,脑失所养,从而出现记忆力减退、思维迟钝等症,治当益气健脾养血以养脑神。若脾失升清,清阳不升,浊阴不降,则脑气失养,九窍不利而出现健忘、头昏、眼花、耳鸣等症,治当益气升阳。

 

摘要
背景:
脾虚证不仅对人体的免疫系统和消化系统等产生不同程度的影响,且脾与脑存在密切的生理联系,因此脾虚证还会影响到中枢神经系统的正常功能。
目的:分析电针在脾虚证大鼠海马区神经干细胞增殖分化中的作用机制。
方法:60只SD大鼠随机分为3组:正常组、对照组以及电针组。对照组和电针组均制备脾虚证动物模型,模型制备后2周,电针组实施电针治疗。造模后2周,测量正常大鼠和模型大鼠的体质量。治疗后1,2,3,4周,分别取各组5只动物进行组织学检测,观察海马区神经干细胞增殖分化情况。
结果与结论:①体质量:造模后2周模型组显著低于正常组(P < 0.05);②BrdU阳性细胞数:造模后2,3,4周电针组均显著高于正常组和对照组(P < 0.05);③BrdU/巢蛋白阳性细胞数:对照组造模后1周显著低于同期正常组和电针组,2,4周显著低于同期电针组,3周显著低于同期正常组(P< 0.05);2,3,4周电针组均显著高于正常组(P < 0.05);④BrdU/胶质纤维酸性蛋白阳性细胞数:造模后1,2,4周对照组显著低于其他2组,2周电针组显著高于正常组(P < 0.05);⑤BrdU/神经元特异性烯醇化酶阳性细胞数:造模后1,2周对照组显著低于其他2组,3周电针组显著高于正常组(P < 0.05)。⑥结果表明,电针可以有效促进海马区神经干细胞的增殖,并促进细胞向星形胶质细胞、神经元方向进行分化。

Abstract:

BACKGROUND: Spleen deficiency has varying impact on the immune system and digestive system of the human body, and can also damage the normal function of the central nervous system as there is a close relationship between the spleen and brain.
OBJECTIVE: To explore the effect of electroacupuncture on the proliferation and differentiation of neural stem cells in the rat hippocampus of spleen deficiency syndrome.
METHODS: Sixty Sprague-Dawley rats were randomly divided into three groups: normal, control and electroacupuncture groups. The animal model of spleen deficiency syndrome was prepared in the control group and electroacupuncture group. Two weeks after modeling, rats in the electroacupuncture group were given electroacupuncture treatment, and the changes of body mass in normal rats and model rats were measured. Five rats from each group were taken to observe the histological changes of neural stem cells in the hippocampus at 1, 2, 3, 4 weeks after treatment.
RESULTS AND CONCLUSION: The body mass of rats in the model group was significantly lower than that in the normal group at 2 weeks after modeling (P < 0.05). In the electroacupuncture group, the number of BrdU positive cells was significantly higher than that in the normal group and control group at 2, 3, 4 weeks after modeling (P < 0.05); the number of BrdU/Nestin positive cells was significantly higher than that in the normal group at 2, 3, 4 weeks (P < 0.05); the number of BrdU/glial fibrillary acidic protein positive cells was significantly higher than that in the normal group at 2 weeks (P < 0.05); and the number of BrdU/neuronspecific enolase positive cells was significantly higher than the normal group at 3 weeks (P < 0.05). In the control group, the number of BrdU/Nestin positive cells was significantly lower than that in the normal group and electroacupuncture group at 1 week after modeling, significantly lower than that in the electroacupuncture group at 2 and 4 weeks, and significantly lower than the normal group at 3 weeks (P < 0.05); the number of BrdU/glial fibrillary acidic protein positive cells was significantly lower than that in the normal group and electroacupuncture group at 1, 2, 4 weeks; and the number of BrdU/neuronspecific enolase positive cells was significantly lower than that in the normal group and electroacupuncture group at 1, 2 weeks. Taken together, these experimental findings show that electroacupuncture treatment effectively promotes the proliferation of hippocampal neural stem cells that are induced to differentiate into astrocytes and neurons.
