摘要
目的研究针刺合谷穴引起的脑功能的即刻效应和后效应(时间变化规律)。方法用改进时间簇分析(modified temporal cluster analysis,MTCA)方法对12名健康志愿者针刺合谷穴功能磁共振成像(fMRl)的数据进行处理,得到针刺后脑功能变化的时间和趋势。结果针刺合谷穴在进针后7～9s和拔针后高峰后,还会不规律出现一些小的高峰。结论针刺合谷穴对中枢神经系统影响具有时间特性。
Objective To explore instant and latent cerebral effects (time-associated features) that are induced by acupuncturing of acupoint LI4(Hegu). Methods MTCA(modified temporal cluster analysis) was employed to process the fMRI(functional magnetic resonance imaging) data collected from 12 healthy volunteers subject to acupuncturing of LI4 (Hegu). Features of brain function associated with time and trend responding to acupuncture were obtained. Results Acupuncturing of LI4 caused peaks at 7-9s after pricking in and withdrawal, and small peaks ensued randomly as well. Conclusion Acupuncturing of LI4 (Hegu) effects central nervous system, displaying time-associated features.
