摘　　要：目的利用功能磁共振成像技术探讨配伍针刺足阳明胃经(ST)原穴与合穴后脑功能变化情况。方法对30名健康志愿者使用电针同时刺激原穴(冲阳,ST42)、合穴(足三里,ST36)后,采用血氧水平依赖法进行功能磁共振成像;随机选择30名健康志愿者中的10名针刺非穴位点作为对照组。以P<0.001,k≥30作为阈值,处理结果叠加到标准脑上显示。结果试验组脑功能激活区有双侧颞上回(22区)、双侧缘上回(40区)、双侧小脑、双侧扣带回及扣带回峡(32区和30区)、双侧顶上小叶(7区);功能减低脑区有双侧眶回(11区)、双侧颞极(38区)、右侧额下回(47区)、右侧枕颞内侧回(36区)。对照组激活区包括颞上回、中央前回、扣带回、丘脑、岛叶、小脑等。对照组激活脑区的范围、信号强度及数量(12个)显著小于试验组(23个)。结论配伍刺激ST的原穴、合穴后,可以激活、降低属于"内脏脑"的不同脑区及躯体感觉区的7区,使之达到新的功能平衡而实现止痛效果。Objective To explore the functional brain localization with magnetic resonance imaging （MRI） after acupuncturing the Yuan-Source and He-Sea acupoints of Stomach Meridian of Foot-Yangming （ST）. Methods The study was performed in 30 healthy volunteers who underwent acupuncture at Yuan- Source acupoint （Chongyang, ST42） and He-Sea acupoint （Zusanli, ST36） （ST group）. Ten of these were also underwent acupuncture at the non-acupoints as the control group. Blood oxygenation level dependent functional MRI was performed. Results In the ST group, signal increasing areas were demonstrated in bilateral superior temporal gyri （ Broadmann 22 ） , bilateral supramarginal gyri （ Broadmann 40 ） , bilateral cerebellar hemispheres, bilateral cingulate gyri and isthmus of cingulate gyri （ Broadmann 32, 30） , bilateral superior parietal lobules （ Broadmann 7 ） ; signal decreasing areas were shown in bilateral orbital gyri （ Broadmann 11 ）, bilateral temporal pole （ Broadmann 38 ）, right inferior frontal gyrus （ Broadmann 47 ） and right medial occipitotemporal gyrus （ Broadmann 36）. In the control group, signal increases areas were demonstrated in superior temporal gyri, precentral gyri, cingulate gyri, thalamus, insula and cerebellum. The size, signal intensity and number of increasing areas in control group are less than in ST group. Conclusion Combined acupuncture of Yuan- Source and He-Sea acupoints of ST can activate and decrease the multiple brain regions of ＂splanchnic brain＂ and thus reach a new functional balance to relieve pain.
