电针中脘对阴虚体质人群任脉上浅表微循环血流灌注量的影响

目的:探讨电针中脘穴对阴虚体质受试者任脉能量代谢的影响。方法:对200名福建中医药大学在校学生进行体质问卷,共收集到阴虚体质志愿者15例(女9例,男6例)。应用激光多普勒血流仪监测其常态下、电针中脘穴20 min、取针后10 min,任脉线上膻中穴、下脘穴及气海穴浅表微循环血流灌注量(MBPU)。结果:电针阴虚体质受试者中脘穴20min:1膻中穴浅表MBPU显著降低,与电针前比差异有统计学意义(P0.05);2下脘穴浅表MBPU较针前有所下降,但差异无统计学意义(P0.05);3气海穴浅表MBPU有所下降,与电针前比差异有统计学意义(P0.05)。与电针中脘穴20min相比,取针后10min3个穴位上浅表MBPU的改变均无统计学意义(P0.05)。结论:电针中脘穴能降低阴虚体质受试者任脉线上浅表MBPU,尤以膻中穴MBPU下降明显。

Effects of Electroacupuncture Stimulation of Zhongwan(CV 12)on Skin Microcirculatory Blood Perfusion Levels along the Conception Vessel in Yin-deficiency Constitution Volunteers

Objective To observe the effect of electroacupuncture(EA)stimulation at Zhongwan(CV 12)on the skin microcirculatory blood flow along the Conception Vessel(CV)in yin-deficiency constitution volunteers.Methods A total of 16yin-deficiency constitution volunteers(9woman and 6men)from 200 students of Fujian University of Traditional Chinese Medicine finished a body constitution questionnaire and showed a yin-deficiency constitution.Skin microcirculatory blood perfusion units(MBPU)at Danzhong(CV 17),Xiawan(CV 10),and Qihai(CV 6)of the CV were measured by using a Laser Doppler Flowmetry(Peri Flux 5000)in normal constitution,before and after EA stimulation of Zhongwan(CV 12)for 20 min.Results Under normal condition,the cutaneous MBPU values were significantly lower in the Qihai(CV 6)than in both Danzhong(CV 17)and Xiawan(CV 10)(P<0.01).After EA stimulation of CV 12 for 20min,the MBPU values were significantly decreased in the CV 17 and CV 6acupoint regions compared with pre-stimulation(P<0.05).No significant changes of skin MBPU were found in Xiawan(CV 10)after EA stimulation of CV 12(P>0.05).Conclusion EA at Zhongwan(CV 12)can reduce the skin MBPU values of CV 6and CV 17 of the Conception Vessel in yin-deficiency constitution volunteers.
