中文摘要：

目的：基于功能性磁共振脑功能成像（fMRI）技术，观察针刺缺血性中风患者右侧外关穴对脑部功能区激活／负激活的作用。方法：左脑缺血性中风患者6例，接受右侧外关穴针刺。针刺过程中接受蹦RI扫描，所得数据由SPM2分析、比较。结果：与留针状态比较，针刺左脑缺血性中风患者外关穴捻针时，激活的脑部功能区为BA7、10、17、18、19、31、39、40区和小脑前、后叶，负激活的脑区为BA1、4、22、45区。结论：针刺左脑缺血性中风患者右侧外关穴，能较为特异地激活主管感觉的脑区，负激活主管运动的脑区，可能是外关穴治疗缺血性中风的机制之一。

英文摘要：

Objective i To observe the cerebral activating/deactivating effects of needling at right Waiguan （ TE5 ） of ischemic stroke patients based on the technique of functional magnetic resonance imaging （fMRI）. Methods：Six ischemic stroke patients received needling at right side TE5, and received cerebral scan of fMRI in the meantime. The data were processed by SPM2. Results： compared to that of needling resting state, twirling the needle could activate BA7,10,17,18,19,31,39,40 and cerebellum, deactivate BA1,4,22 and 45. Conclusion：Needling at TE5 of the ischemic stroke patients could activate the cerebral regions controlling sensation, and deactivate the cerebral regions controlling movement, which had a close relationship with its mechanism on stroke treatment.
