目的：观察常态下阴虚阳虚体质任脉线上浅表微循环血流灌注量（MBPU）的表现,比较两种不同体质任脉线上浅表MBPU的差异,探讨电针对其影响。方法：对200名福建中医药大学在校大学生进行体质问卷,共收集阴虚体质志愿者15名（女10名,男5名）,阳虚体质志愿者15名（女10名,男5名）,两组年龄、性别无明显差异。应用激光多谱勒血流仪系统分别对筛选出来的阴虚、阳虚体质志愿者进行常态下以及电针中脘穴时任脉线上膻中穴、下脘穴及气海穴浅表MBPU进行观察。结果：常态下志愿者阴虚体质膻中穴浅表MBPU明显高于阳虚体质（P〈0.01）;常态下阴虚体质的志愿者膻中穴、下脘穴及气海穴浅表MBPU相对较高,电针中脘穴可使其浅表MBPU明显降低（P〈0.01）;常态下阳虚体质的志愿者膻中穴、下脘穴及气海穴浅表MBPU相对较低,电针中脘穴可使其浅表MBPU明显升高（P〈0.01）。结论：阴虚和阳虚体质志愿者浅表MBPU的表现不尽相同,电针具有双向的调节作用。

英文摘要：

Objective： To investigate the differences in the superficial microcirculation blood perfusion units（MBPU） on Ren meridian between the yin deficiency constitution and yang deficiency constitution, and to explore how electro-acupuncture（EA） to act in the MBPU. Methods： Two hundred college students at Fujian University of Chinese Medicine were performed the constitution questionnaire, among of which 15 cases of volunteers with yin deficiency constitution and 15 cases of volunteers with yang deficiency constitution were ultimately included into this study. And, no significant differences in age and gender were found between the two groups due to 10 female and 5 male in each group. Laser Doppler flowmeter system was used to detect the superficial MBPU on the acupoints of Ren meridian including Danzhong（CV17）, Xiawan（CV10） and Qihai（B24）, when the body was yin deficiency constitution and yang deficiency constitution, or treated by EA at the Zhongwan（CV12） acupoint. Results： The results of superficial MBPU on the Danzhong（CV17）, Xiawan（CV10） and Qihai（B24） acupoints showed that yin deficiency constitution volunteers was significantly higher than the yang deficiency constitution volunteers, and the two groups had significant difference（P〈0.01）. Yin deficiency constitution volunteers showed an increased superficial MBPU on the Danzhong（CV17）, Xiawan（CV10） and Qihai（B24） acupoints, which could be decreased by the treatment with EA at the Zhongwan（CV12） acupoint, and there were significant differences between the two groups（P〈0.01）. Yang deficiency constitution volunteers showed an decreased superficial MBPU on the Danzhong（CV17）, Xiawan（CV10） and Qihai（B24） acupoints, which could be increased by the treatment with EA at the Zhongwan（CV12） acupoint, and there were significant differences between the two groups（P〈0.01）. Conclusion： The performance of superficial MBPU could vary depending on the different TCM constitution. Additional
