摘要:

目前研究虽证实针灸能够有效治疗脑缺血,但其针刺手法和针刺持续时间不同都会影响针刺的效果。实验采用电针仪对大脑中动脉闭塞大鼠进行治疗,以捻转针刺法针刺大鼠右侧内关穴3 Hz,5,60,180s治疗,寻找治疗缺血性脑卒中的最恰当针刺手法和持续时间的组合。结果显示,与针刺大脑中动脉闭塞大鼠内关3 Hz,5,180s比较,针刺3 Hz,60s的大鼠脑血流量较高,神经功能恢复较好,脑梗死体积也变小,提示捻转针刺法针刺大鼠内关3 Hz,60s的组合对大脑中动脉闭塞有较好的治疗效果。

Abstract:

Acupuncture is regarded as an effective therapy for cerebral ischemia. Different acupuncture manipulations and durations may result in different therapeutic effects. In the present study, the Neiguan (PC6) acupoint of rats with occluded middle cerebral arteries was needled at a fixed frequency (3 Hz) with different durations, i.e., 5, 60 and 180 seconds under a twisting-rotating acupuncture method. Results showed that different durations of acupuncture had different therapeutic effects, with 60 seconds yielding a better therapeutic effect than the other two groups. This duration of treatment demonstrated rapid cerebral blood flow, encouraging recovery of neurological function, and small cerebral infarct volume. Experimental findings indicated that under 3 Hz frequency, the treatment of needling Neiguan for 60 seconds is effective for ischemic stroke.
