摘　　要：目的:观察电针中脘穴对阳虚体质志愿者任脉线上能量代谢的影响,探讨电针调节作用与体质的关系。方法:对200名福建中医药大学在校大学生进行体质问卷,收集平和、阳虚体质志愿者各18例,应用激光多谱勒血流仪监测其常态下、电针中脘穴20min时,任脉上膻中、下脘及气海穴浅表微循环血流灌注量(microcirculatory blood perfusion units,MBPU)。结果:(1)在电针前,1阳虚体质组膻中、下脘、气海穴浅表微循环血流灌注量均低于平和体质组,其中膻中穴差异有统计学意义(P<0.01),下脘、气海穴差异无统计学意义(均P>0.05);2平和体质组3个穴位进行比较,膻中穴浅表MBPU高于下脘穴,但差异无统计学意义(P>0.05);膻中、下脘穴浅表MBPU高于气海穴(均P<0.01);3阳虚体质组3个穴位进行比较,膻中穴浅表MBPU低于下脘穴,高于气海穴(P<0.05,P<0.01);下脘穴浅表MBPU显著高于气海穴(P<0.01)。(2)与电针前相比,两组受试者电针中脘20min时膻中、下脘、气海穴MBPU均显著升高(均P<0.01)。(3)阳虚体质组电针中脘20min时膻中、气海穴微循环血流灌注量上升率高于平和体质组,但差异无统计学意义(均P>0.05)。结论:阳虚体质志愿者任脉上能量代谢出现下降,尤以膻中穴明显;电针可通过调节机体经脉线上MBPU,升高平和、阳虚体质志愿者任脉上能量代谢。Objective To observe the effect of electroacupuncture（EA）at Zhongwan（CV 12）on the energy metabolism along the conception vessel（CV）in volunteers with yang-deficiency constitution,and to explore the relationship of electroacupuncture regulation and body constitution.Methods Eighteen volunteers with mild constitution and 18 volunteers with yang-deficiency constitution were collected out of 200 students of Fujian University of TCM by body constitution questionnaire.Skin microcirculatory blood perfusion units（MBPU）at Danzhong（CV 17）,Xiawan（CV 10）and Qihai（CV 6）of CV were measured by a laser Doppler flowmetry in the normal condition and after EA stimulation at Zhongwan（CV 12）for 20 min.Results（1）Before treatment,1MBPU values at Danzhong（CV 17）,Xiawan（CV 10）and Qihai（CV 6）in the yang-deficiency constitution group were lower than those in the mild constitution group,but there was no statistical significance（both P〈0.05）except Danzhong（CV17）（P〈0.01）.2As for the three acupoints in the mild constitution group,MBPU level of Danzhong（CV 17）was higher than that of Xiawan（CV 10）without statistical significance（P〈0.05）,and MBPU values of Danzhong（CV17）and Xiawan（CV 10）were higher than that of Qihai（CV 6）（both P〈0.01）.3About the three acupoints in the yang-deficiency constitution group,MBPU result of Danzhong（CV 17）was lower than the value of Xiawan（CV10）,but higher compared with Qihai（CV 6）（P〈0.05,P〈0.01）.MBPU of Xiawan（CV 10）was higher than Qihai（CV 6）as well（P〈0.01）.（2）MBPU values of Danzhong（CV 17）,Xiawan（CV 10）and Qihai（CV 6）were increased apparently compared with those before treatment after EA stimulation at Zhongwan（CV 12）for 20 min in the two groups（all P〈0.01）.（3）The rise rates of MBPU level about Danzhong（CV 17）and Qihai（CV 6）in the yang-deficiency constitution group were higher than those in the mild constitution group without statistical significance
