摘　　要： 目的分析针刺足三里穴脑组织磁共振功能成像的影响。方法选取96例健康志愿者，按数字表法随机分为穴位组与非穴位组，穴位组手法针灸足三里，非穴位组针灸假穴，并用磁共振进行脑功能成像，比较两组脑功能图，进行统计学分析。结果所有受试者均配合完成试验，穴位组进行穴位刺激，均有明显的针感，非穴位组有轻度的针感，其中穴位组共激活13个脑区；非穴位组为10个脑区，其中丘脑、桥脑、缘上回非穴位组无激活；两组激活例数比较：基底节区（28例比5例）和颞叶区（38例比21例）差异有统计学意义（χ2=36．250，P〈0．05）；在颞叶中左半球激活反应率（73．68％）明显高于右半球（36．84％），差异有统计学意义（χ2=8．265，P〈0．05）；在基底节区中，左半球激活反应（67．86％）虽高于右半球（42．86％），但差异无统计学意义（χ2=0．724，P〉0．05）。结论手法针灸足三里穴通过脑内磁共振功能成像的研究显示，足三里穴位可激活脑内多功能区，通过脑对身体器官进行调节与治疗，从而证明了经络传感的存在以及其独特性。 Objective To study the effect of acupuncture Zusanli on brain functional magnetic resonance imaging. Methods 96 healthy volunteers were randomly divided into acupoint group and non - acupoint group. The acupoint group received acupuncture Zusanli, and the non - acupoint group received manipulation, acupuncture and sham acupuncture. The fungtional brain imaging was determined by MRI, the brain functional images were compared between two groups. Results All subjects were matched with the end of the experiment,the acupoint group received aeupoint stimulation, had obvious needling sensation, the non - acupoint group had mild needling sensation. The acupoint group activated 13 brain regions, non- acupoint group in 10 brain regions, the thalamus,pons, supramarginal gyrus in non- acupoint group without the activation. In the basal ganglia （28 cases vs. 5eases ） and temporal lobe （38cases vs. 21 cases） between the two groups were activated, the difference was statistically significant（ χ2 = 36.250, P 〈 0.05 ）. In the temporal lobe, the left hemisphere response rate （73.68%） was significantly higher than the fight hemisphere （ 36.84% ）, the difference was statistically significant （ χ2 = 8. 265, P 〈 0.05 ）. In the basal ganglia, left hemisphere activation（67.86% ） was higher than that of the right hemisphere（42.86% ）, but the difference was not statistically significant （ χ2 = 0. 724, P 〉 0. 05 ）. Conclusion The research of acupuncture by brain functional magnetic resonance imaging showed that Zusanli acupoint can activate the brain function area through brain regnlation and treatment of body organs, so as to prove the existence of its own and meridian sensing characteristics.
