Study Procedures①Subjects (ischemic stroke patients or healthy subjects) were conventional closed vision and auditory till the end of the fMRI detects(Earplugs from Aearo Company, USA, batch R5A018; goggles from Hanjiang Jiang Xinhua Tourist Products Factory, Yangzhou, China, batch XHYZ-001).②Ischemic stroke patients received the TE5and non-acupuncture stimulation randomly, healthy volunteers only to accept TE5acupuncture stimulation, the same subjects received sham acupuncture and real acupuncture in succession. TE5locates on the forearm,2cun (cun, a special length unit in acupuncture. The distance between the transverse crease of the elbow and that of the wrist is12cun.) above the transverse crease of the dorsum of wrist, between the radius and ulna. Location of the sham acupoint:Level with TE5, on the midpoint of the lines in forearm where Sanjiao Meridian of hand-Shaoyang and Small intestine meridian of hand-Taiyang travel.③fMRI scanning was performed with a3.0T whole-body MRI scanner (GE, Bethesda, MD, USA) and a standard head coil. The subjects used earplugs (Aearo Co., Hartford, CT, USA) and were blindfolded (Xinhua Tourism Co., Hangzhou, China). Each subject rested on the bed for5-10minutes before the scan.3D anatomy images were collected with a T1-weighted3D gradient echo-pulse fast spin sequence prior to acupuncture, with axial view T1fluid-attenuated-inversion-recovery scan (repetition time,2300ms; echo time,21ms; time of inversion,920ms; slice thickness,6.0mm; gap1.0mm for20layers for a total of2minutes45seconds; field of view,24cm×18cm; matrix,320×256; number of excitations=2; field of view echo train length,9; and band width,50).④Acupuncture was performed by one physician, who had engaged in clinical acupuncture for more than three years. The tubes were purchased from Dongbang AcuPrime Co.(Exeter, England) and the0.3cm×40cm silver needles from Zhongyan Taihe Co.(Beijing, China). Volunteers received sham acupuncture stimulation on right TE5/non-point6minutes and30seconds, at the same time scanned sham acupuncture stimulation stage blood oxygen level dependent (BOLD) functional magnetic resonance6minutes and30seconds. Sham needling:the location of TE5, the sterilization, the needling instruments were the same as above. The stimulation was designed with the block procedure of the alternative of gently touching the skin with the tip of the needle lmm above the tube for30seconds or non-touching the skin with lifting the needle for each30seconds, and the stimulation was lasted to360seconds totally, too. Detection parameters:The GR (gradient the recalled)/EPI (Echo-Planar imaging)/90, TR3000ms/20ms/FE Flip angle90, FOV24cm x24cm, thickness6mm/interval1.0mm, matrix96×96/NEX=1, PhasePer location:130,2600/6min30s.⑤And3D scanning after6minutes2seconds. Detection parameters:Ax (axial) of3D T1FSPGR (fast spoiled gradient echo)/20T1450, TR7.6ms/TE 3.3ms, FOV24cm x18cm, Flip angle20Bandwidth25, matrix256×256/NEX=1, thick1.2mm/-0.6mmov, a total of248layers,6min2s.⑥Continue true acupuncture (needles instrument the same as④) to stimulate the right TE5on the same group of patients6minutes and30seconds, the true acupuncture stimulation stage BOLD functional MRI scans of6minutes and30seconds. True needling:sterilized the local skin routinely and inserted the needle with tube insertion method (the tubes were from DONGBANG AcuPrime Co., England and the silver needles of0.3×40cm were from Zhongyan Taihe Co., China). The physician sticked the auxiliary part of the tube on the local skin, put the needle into the matching tube over the acupoint and tapped the end of the needle to make the tip of the needle inserted, removed away the tube and punctured the needle to the depth of15±2mm, and twirled the handle of the needle to get the needling sensation. Then the physician manually stimulated the needle with an even reinforcing and reducing manipulation by twirling the needling with±180°nd60times/min. The stimulation was designed with the block procedure of the alternative of twirling or non-twirling for each30seconds, and the stimulation was lasted to360seconds totally. Detection parameters the same with④.9. Study Procedures①The fMRI data were processed with the software SPM2(http://www.fil.ion.ac.uk) MATLAB6.5(The MathWorks, Inc., USA) platform for processing to obtain statistical parameters Figure. a. Pre-Processing:Slight movements of the head were corrected; The images were normalized to the standard brain template of the Montreal Neurological Institute space; and then smoothed spatially to reduce errors produced during imaging construction and eliminate tiny differences in brain structures among subjects; b. First analysis:The smoothed data were analyzed with a generalized linear model voxel by voxel. The value of each voxel was calculated by two-sample t-tests, and statistical parametric mapping was based on the t values (P<0.001, uncorrected, K>30). Significant changes in different brain regions during stimulation and control conditions were identified and superimposed on the standard brain image mode of each subject’s anatomic images; c. Secondary Analysis:the activated/deactivated con file of the model of stroke patients and normal controls was further analyzed using a two-independent sample t-test. The remaining procedures were the same as those reported in.②Determine the brain area location and anatomical position:Central coordinates from statistical parameters determined using SPM software package were reproduced and input in Talairach Client (download from http://www.talairach.org/client.html) to obtain the anatomical location and the BA range of the functional areas of the brain, which were corrected by a physician of the neurological medicine department according to anatomic knowledge and clinical experience.Results1.
