Comparison of fMRI cerebral functional imaging between needling Waiguan (SJ5) and combined SJ5 and sham point

[Objective] To observe the cerebral activating effects of needling Waiguan (SJ5) and the combined SJ5 and sham point in healthy volunteers.[Methods] Sixteen healthy volunteers were randomly divided into SJ5 group and SJ5 with sham point group. They received needling in different points on the right hand respectfully. Super nuclear magnetic resonance (1.5T,GE Co.) was used to scan the brain and the obtained experimental data of the regional brain were processed and analyzed by method of Region of Interest (ROI). [Results] Both needling in SJ5 and combined SJ5 and sham point could activate bilateral parietal,frontal,occipital and temporal lobes,basal ganglia,cingulate gyri,hippocampus,cerebellum,and pons in different degree. Compared with needling combined SJ5 and a sham point,Acupuncture in SJ5 could specially activate the right cerebellum (P0.05),and had a tendency to show that needling SJ5 could also active the left parietal lobe,right frontal and temporal lobes more intensively. [Conclusion] Based on the analysis of fMRI cerebral imaging,the compatible relationship of SJ5 and the combined SJ5 and sham point is not simply like that of 1+0=1.
