目的:探讨"长强"配"太溪"穴电针治疗自闭症神经发育障碍仔鼠的靶向调控机制。方法:选取已成功受孕 SD大鼠 10 只,分为造模组和非造模组,每组 5只,造模组大鼠给予丙戊酸钠 600 mg/kg灌胃造模,非造模组给予等量生理盐水灌胃。将造模组大鼠所产 36只仔鼠随机分为电针穴位组、电针非经非穴组和模型组,每组 12只,随机选取非造模组仔鼠所产的仔鼠 12 只作为对照组。电针穴位组仔鼠在出生第 24天即开始电针长强和太溪穴位。电针非经非穴组避开经络和穴位针刺。分别于干预前后对所有仔鼠行旷场实验和 Morris水迷宫测试。并取仔鼠腹主动脉血检测血清谷氨酸(Glu)、γ-氨基丁酸(GABA)水平。断头处死留取海马组织,通过实时荧光定量聚合酶链式反应(RT-PCR)测定仔鼠海马组织γ-氨基丁酸 A型受体(GABAAR)mRNA相对表达水平,采用蛋白免疫印迹法(Western Blot)测定仔鼠海马组织糖原合酶激酶-3β(GSK-3β)、β-catenin和微白蛋白(PV)相对表达水平。结果:旷场实验结果表明,经干预后,电针穴位组水平得分和垂直得分高于模型组和电针非经非穴组,低于对照组,差异有统计学意义(P<0。05)。Morris水迷宫测试结果表明,经干预后,与模型组和电针非经非穴组比较,电针穴位组逃避潜伏期缩短,而穿越次数增加,平台停留时间延长,差异有统计学意义(P<0。05)。与模型组比较,电针穴位组仔鼠 Glu、GABA、海马 GABAAR mRNA、β-catenin和 PV相对表达水平降低,而 GSK-3β蛋白相对表达水平上调,差异有统计学意义(P<0。05)。结论:针刺长强和太溪穴可有效改善自闭症仔鼠的空间学习和记忆能力,靶向调控自闭症神经发育障碍,其具体机制可能与通过促进 GABA神经通路的兴奋-抑制平衡,同时作用于Wnt/β-catenin信号通路中的重要调节因子有关。
The Treatment of Autism Neurodevelopmental Disorders with"Changqiang"and"Taixi"Acupoints Electroacupuncture
Objective:To explore the targeted regulatory mechanism of"Changqiang"combined with"Taixi"acupoints electroacupuncture in the treatment of autistic neurodevelopmental disorders in offspring mice.Methods:Ten SD rats were divided into model group and non-model group,with 5 groups in each group.The rats in the model group were given 600 mg/kg sodium valproate by gavage to establish models,and the rats in the non-model group were given the equal volume of normal saline by gavage.The offspring of the rats in the model group were randomly divided into electroacupuncture acupoint group,electroacupuncture non-meridian non-acupoint group and model group with 12 rats,and 12 offspring rats from the non-model group were randomly selected as the control group.The rats in the electroacupuncture acupoint group started electroacupuncture at Changqiang and Taixi acupoints at the 24th day after birth.The electroacupuncture non-meridian non-acupoint group avoided meridian and acupoint acupuncture.Open field experiment and morris water maze test were performed before and after intervention.The hippocampus was collected by decapitation,and the relative expression level of γ-aminobutyric acid type A receptor(GABAAR)mRNA in the hippocampus of the offspring were determined by real-time quantitative PCR(RT-PCR).The relative expression levels of glycogen synthase kinase-3β(GSK-3β),β-catenin and microalbumin(PV)were measured by Western Blot.Results:The open field experiment results showed that after intervention,the horizontal and vertical scores of electroacupuncture acupoint group were higher than those of model group and electroacupuncture non-meridian non-acupoint group,but lower than those of the control group(P<0.05).Morris water maze test results showed that after intervention,compared with the model group and the electroacupuncture non-meridian non-acupoint group,the escape latency of the electroacupuncture point group shortened,the crossing times increased,and the platform residence time prolonged(P<0.05).Compared with model group,the relative expression levels of Glu,GABA,GABAAR mRNA,β-catenin and PV in hippocampus of rats in electroacupuncture acupoint group decreased,while the relative expression levels of GSK-3βprotein increased(P<0.05).Conclusion:Acupuncture at Changqiang and Taixi acupoints can effectively improve the spatial learning and memory ability of autistic offspring mice,and target the regulation of autistic neurodevelopmental disorders.The specific mechanism may be related to promoting the excitation-inhibition balance of GABA neural pathway and acting on important regulatory factors in Wnt/β-catenin signaling pathway.
