捻转和非捻转刺激太溪穴后脑激活状态的功能磁共振成像研究

目的：观察功能磁共振成像了解捻转刺激太溪穴和非捻转刺激所引起的脑激活区状态。 方法：纳入健康青年志愿者12名，选取右侧太溪穴，采用组块刺激模式，静息阶段与刺激阶段交替出现，重复3次，分为3个组块。刺激为手法捻转行针或非捻转，非捻转即手放在针柄，但不进行任何操作。扫描后图像使用SPM2进行后处理。 结果：捻转刺激太溪穴主要激活了右侧颞上回BA22，左侧的额中回BA46，其次为左右顶叶的中央后回BA2，BA3，左额叶的额下回BA45和左顶叶的顶下小叶BA40；而非捻转刺激则没有激活。 结论：捻转刺激太溪穴和非捻转刺激的激活不同，与本经相关的经络、脏腑联系密切相关。

Magnetic resonance imaging study of twisting or untwisting Taixi acupoint (KI3) on brain function

OBJECTIVE: To identify the influence of twisting or untwisting Taixi (K13) on the brain function by observing functional magnetic resonance imaging. METHODS: Twelve healthy young cases were enrolled in this research. A block design including three blocks which baseline and stimulation appear alternately was adapted. In stimulation phase, the needle was twisted manually, or not twisted. Scanned images were analyzed using SPM2. RESULTS: The right superior temporal gyrus (BA22), left medial frontal gyrus (BA46), followed by right and left postcentral gyrus of parietal lobe (BA2, BA3), left inferior frontal gyrus (BA45) and left inferior parietal lobule (BA40) were evoked by acupuncture at Taixi, but there was no activeation area after untwisting acupoint. CONCLUSION: The different areas evoked by twisting or untwisting Taixi acupoint are closely related with the internal organs as well as the course of the channels and collaterals.
