电针对人脑运动功能区糖代谢的影响

目的比较电针头部穴位和肢体穴位对大脑运动功能区糖代谢的影响。方法采用Talairach大脑立体定位法，运用正电子发射断层扫描（PET）观察运动状态下正常人电针前后大脑细胞葡萄糖代谢的变化。结果①电针百会和左侧曲鬓穴引起双侧大脑顶上小叶、楔前叶葡萄糖代谢增高，但以左侧大脑为主；②电针右侧曲池、足三里等穴位，左侧中央前回、右侧旁中央小叶、额内侧回、双侧小脑、壳核等神经元细胞葡萄糖代谢发生了改变。结论针刺不同穴位均可改变大脑双侧有关运动区域的代谢，不同部位的穴位激活大脑不同的运动功能区。针剌的作用是综合调节的过程。

Comparison Study on Effects of Electroacupuncture on Glucose Metabolism of Cerebral Motor Function Areas

Objective To compare the effect of electroacupuncture at head points and body points on glucose metabolism of the cerebral motor function regions in normal subjects. Methods To observe the change of glucose metabolism of cerebral motor area in normal subjects between before and after acupuncture during the movement by PET. Talairach coordinates （Atlas of brain） and statistical parametric mapping （SPM） software were used to deal with the acquired imaging data.Results ①Acupuncture at Baihui （GV20） and left Qubin （GB7） could increase metabolism of glucose in bilateral Lps and precuneus, the activation＇ of left area in the brain being more significant. ②Acupuncture at right Quchi （LI11） and Zusanli （ST36） change metabolism of glucose in left gyms precentralis, right loblus paracentralis, right gyms frontalis medialis, both cerebellums and both putarnens. Conclusion All acupoints can change glucose metabolism in cerebral structures related to motor function in the bilateral cerebral hemispheres, different acupoints active different motor areas. The function of acupuncture is a kind of comprehensive regulative process.
