艾灸足三里、悬钟对缺血性中风脑血管功能的影响及其临床意义

目的:探讨艾灸足三里、悬钟对缺血性中风的作用机理,并对临床疗效作出评价。方法:采用序贯试验设计方法分治疗组与对照组。治疗组在基本对症治疗基础上加用艾灸足三里、悬钟,每日1次,连续治疗20天;对照组采用基本对症治疗20天。以经颅多普勒观察随机配对设计的成对缺血性中风患者治疗前后脑血管功能变化,以治疗前后神经功能缺损程度评价其临床疗效。结果:各研究指标的试验线都达到序贯试验图的有效边界,与对照组相比,P<0·05。结论:艾灸足三里、悬钟对脑血管舒缩反应、脑血流自动调节、侧枝循环的建立等功能有良好的改善作用,并能促进神经功能的恢复。

Effects of moxibustion at Zusanli (ST 36) and Xuanzhong (GB 39) on cerebrovascular function in the patient of ischemic apoplexy

Objective To explore the mechanism of moxibustion at Zusanli (ST 36) and Xuanzhong (GB 39) in treatment of ischemic apoplexy, and to evaluate the clinical therapeutic effect. Methods With the design of sequential trial, the patients were divided into a treatment group and a control group. The treatment group were treated by addition with moxibustion at Zusanli (ST 36) and Xuanzhong (GB 39) on the basis of basic expectant treatment, once each day, for 20 consecutive days; and the control group with basic expectant treatment for 20 days. Changes of cerebrovascular functions before and after treatment were investigated by transcranial Doppler ultrasound (TCD) in the matched-pair's patients of ischemic apoplexy; the clinical therapeutic effect was assessed by nervous function defect before and after treatment. Results All the test lines of the research targets reached to the effective margin of the sequential trial figure, with a significant difference as compared with the control group (P<0.05). Conclusion Moxibustion at Zusanli (ST 36) and Xuanzhong (GB 39) has good regulative action on cerebral vasomotorial response, auto-regulation of cerebral blood flow, and establishment of collateral circulation, and improves recovery of nervous functions.
