支沟穴皮部浅刺与常规针刺功能性磁共振脑功能成像比较

目的运用功能性磁共振（fMRI）脑功能成像技术,研究支沟穴皮部浅刺与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支沟穴皮部浅刺与常规针刺的2次针刺刺激,并进行fMRI脑部扫描。统计皮部浅刺与常规针刺状态下脑部各感兴趣区（ROIs）的激活几率、激活点数和激活强度,并进行比较。结果支沟穴皮部浅刺与常规针刺,对左右不同脑区的激活几率、激活点数和激活强度比较差异均无统计学意义（P〉0．05）。但有趋势表明,常规针刺相对集中地激活对侧脑区,其激活点和强度都相对集中;皮部浅刺,左右两侧脑区均有激活,激活点较为分散,激活强度也相对较弱。结论支沟穴皮部浅刺与常规针刺对不同脑部功能区激活没有显著差异,有趋势表明,常规针刺对脑区的激活更加集中。

Study of fMRI of cerebral functional regions induced by cutaneous and routine needling in Zhigou (SJ6)

Objective To study the activating effect on different cerebral functional regions induced by cutaneous stimulation and routine needling in Zhigou （SJ6） by fMRI. Methods Eight volunteers received 2 times stimulation of cutaneons or routine needling in SJ6, and received the cerebral fMRI scan under the different states. The cerebral activating rate, activating spots and activating strength of different ROIs were compared under the two different stimulating states. Resuits There were no obvious difference in cerebral activating rate, activating spots and activating strength of different ROIs （ P 〉 0.05）, but there was a trend that routine needling mainly activated the opposite cerebral regions and the activating spots and the strength were concentrative, while cutaneous needling could activate bilateral cerebral functional regions and the distribution of the activating spots was scattering and the strength was weaker. Conclusion There was no obvious difference between cutaneous and routine needling in SJ6, but there was a trend that routine needling could intensively activate the cerebral functional regions.
