艾灸对不同人群胃经五输穴微循环血流灌注量的影响

Effect of moxibustion on microcirculatory blood perfusion units of Wushu points of stomach meridian in different population

目的:通过比较健康人群和胃脘痛患者艾灸足三里前后胃经五输穴微循环血流灌注量(MBPU)的变化,探索艾灸对不同人群胃经五输穴微循环血流灌注量(MBPU)的影响及分布特点。方法:分别艾灸20例健康人群和20例胃脘痛患者足三里穴,观察艾灸前后胃经五输穴MBPU变化。结果:健康人群灸前胃经五输穴的MBPU沿着井、荥、输、经、合穴的流注顺序呈规律上升趋势,而胃脘痛患者灸前五输穴MBPU的分布没有明显的规律。与艾灸前相比,胃脘痛患者井穴艾灸后MBPU明显升高(P<0.05),健康人群和胃脘痛患者合穴艾灸后MBPU明显升高(P<0.05),且胃脘痛患者灸后合穴的MBPU升高比健康人群更明显,荥、输、经三穴两组艾灸前后比较差异无统计学意义。结论:疾病会影响五腧穴的血液运行,而艾灸则能明显改善腧穴的气血运行情况,且病理状态下五腧穴对艾灸刺激的应答优于生理状态。

Objective:To explore the effect of moxibustion on the microcirculation blood perfusion(MBPU)of Wushu points of stomach meridian by comparing the changes of MBPU before and after moxibustion on Zusanli(ST36)in healthy people and patients with epigastralgia.Methods:20 healthy people and 20 patients with epigastralgia were treated with moxibustion at Zusanli(ST36),and the changes of MBPU at Wushu points of stomach meridian were observed before and after moxibustion.Results:In healthy people,the MBPU at the Wushu points of the stomach meridian before moxibustion showed a regular upward trend along the flow sequence of the Jing,Xing,Shu,Jing and He points,while the distribution of MBPU at the Wushu points before moxibustion in patients with epigastralgia was not obvious.Compared with before moxibustion,MBPU on Jing point increased significantly in patients with epigastralgia after moxibustion(P<0.05).The MBPU of the two groups was significantly increased after moxibustion at He point(P<0.05),the increase of MBPU was more obvious in patients than in healthy people.There was no statistically significant difference before and after moxibustion at the three acupoints of Ying,Shu and Jing between the two groups.Conclusion:Diseases can affect the blood circulation of the Wushu points,and moxibustion can significantly improve the circulation of qi and blood in the points,and under pathological conditions,the response of the Wushu points to the stimulation of moxibustion is better than that of physiological conditions.
