外关穴和阳陵泉穴区不同层次针刺激活脑区的fMRI比较研究

The fMRI Comparative Study on Different Depth Needling in Waiguan(SJ5) and Yanglingquan(GB34)

目的:运用fMR I脑功能成像技术,研究外关穴配伍阳陵泉穴皮部浅刺和常规针刺对不同脑功能区的激活异同。方法:8例青年志愿者分别接受外关穴配伍阳陵泉穴皮部浅刺和常规针刺的2次针刺刺激,分别进行fMR I脑部扫描。统计皮部浅刺和常规针刺状态下,脑部各感兴趣区(ROIs)的激活几率、激活点数、激活强度,并进行比较。结果:外关穴配伍阳陵泉穴皮部浅刺和常规针刺,对不同脑区的激活数量、激活强度均没有显著性差异,但有皮部浅刺多激活各浅表脑区,而常规针刺还能激活较为内在的某些核团和小脑的趋势。结论:外关穴配伍阳陵泉穴皮部浅刺和常规针刺均能激活脑部不同功能区,有趋势表明,皮部浅刺和常规针刺主要激活的脑区有所不同。

Objective：To compare the different activation on cerebral functional regions between cutaneous stimulation and routine needling in Waiguan（SJ5） and Yanglingquan（GB34） by fMRI.Methods：Eight volunteers received 2 times stimulation of cutaneous or routine needling in SJ5 and GB34,and received the cerebral fMRI scan under the different states.The cerebral activating rate,activating spots and activating strength of different ROIs were compared between the two different stimulating states.Results：The cerebral activating rate,activating spots and activating strength in different ROIs had not any obvious difference,but there was a trend that cutaneous needling mainly activated the superficial cerebral lobes,while the routine needling also activated the deep nucleus and the cerebellum.Conclusion： Both cutaneous needling and routine needling could activate certain cerebral functional regions,and there was the trend of that the cerebral activating actions between cutaneous and routine needling were different.
