针刺健康人委中穴对腰部即刻温度的影响

Effects of acupuncture at Weizhong in healthy people on instant temperature of waist

目的:研究针刺健康人委中穴对腰部即刻温度的影响。方法:纳入甘肃中医学院在校健康研究生10例,最大年龄30岁,最小年龄22岁,平均年龄(24.7±2.3)岁。用随机数字表法分为合谷穴组与委中穴组,利用红外热成像仪采集静息状态下两组腰部(以L1和S1为水平线,两侧腋后线为纵线区域)红外热谱,委中穴组针刺双侧委中穴,合谷穴组针刺双侧合谷穴,两组均采用平补平泻法操作1min后,采集腰部的红外热谱,使用FLIR Quick Plot version热像图处理程序,提取分析两组腰部温度的变化数值。结果:针刺委中穴前后腰部温度变化差值有统计学意义(P<0.05),针刺合谷穴前后腰部温度变化差值无统计学意义(P>0.05);两组针刺后相比,委中穴组腰部温度升高幅度大于合谷穴组,差异具有统计学意义(P<0.01)。结论:针刺委中穴可升高健康人腰部温度,其原因可能与针刺改善腰部血液循环,促进新陈代谢有关,该结果为"腰背委中求"提供实验依据。

Objective： To study effects of acupuncture at Weizhong in healthy people on instant temperature of waist. Methods： 10 healthy graduate students from Gansu TCM College were divided into the Hegu point group and the Weizhong point group, infrared spectra of waist in resting state were collected by infrared thermal imager. The Weizhong point group was given acupuncture at Weizhong point, while the Hegu point group was given acupuncture at Hegu point, two groups were given Pingbu Pingxie therapy for lmin, infrared spectra of waist were collected by FLIR QuickPlot version infrared thermal imager, and temperature changes in waist were analyzed. Results： There were significant differences in temperature changes before and after acupuncture at Weizhong point （P〈0.05）, while no significant differences in temperature changes before and after acupuncture at Hegu point （P〉0.05）. After acupuncture, temperature in the Weizhong point group were significantiy higher than the Hegu point group （P〈0.01）. Conclusion： Acupuncture at Weizhong point could increase temperature of waist for healthy people, and the reason maybe that acupuncture could improve waist blood circulation, and promote metabolism, at the same time, results of this study, provided experimental evidence for Yaobei Weizhong Qiu.
