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, (1)MBPU 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(CV 17) (P<0. 01). (Z)As 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(CV 17) 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(CV 10), 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 after EA at Zhongwan(CV 12) for 20 min(both P>0. 05).
CONCLUSION
The energy metabolism in CV of volunteers with yang-deficiency constitution is declined, especially Danzhong(CV 17). EA can rise energy metabolism in CV of mild or yang-deficiency constitution volunteers through regulating MBPU along meridian.
目的
观察电针中脘（CV 12）对阳虚体质志愿者任脉沿线能量代谢的影响，探讨电针调节与体质的关系。
方法
通过体质问卷从福建中医药大学200名学生中选取18名平和体质志愿者和18名阳虚体质志愿者。采用激光多普勒血流仪在正常状态及电针中脘（CV 12）20分钟后，测量任脉膻中（CV 17）、下脘（CV 10）、气海（CV 6）处的皮肤微循环血流灌注单位（MBPU）。
结果
（1）治疗前，阳虚体质组膻中（CV 17）、下脘（CV 10）、气海（CV 6）的MBPU值低于平和体质组，但除膻中（CV 17）外差异无统计学意义（均P>0.05），膻中（CV 17）差异有统计学意义（P<0.01）。（2）平和体质组的三个穴位中，膻中（CV 17）的MBPU水平高于下脘（CV 10），差异无统计学意义（P>0.05），膻中（CV 17）和下脘（CV 10）的MBPU值高于气海（CV 6），差异均有统计学意义（均P<0.01）。（3）阳虚体质组的三个穴位中，膻中（CV 17）的MBPU结果低于下脘（CV 10），但高于气海（CV 6），差异有统计学意义（P<0.05，P<0.01）。下脘（CV 10）的MBPU也高于气海（CV 6），差异有统计学意义（P<0.01）。（2）两组在电针中脘（CV 12）20分钟后，膻中（CV 17）、下脘（CV 10）、气海（CV 6）的MBPU值均较治疗前明显升高（均P<0.01）。（3）阳虚体质组膻中（CV 17）和气海（CV 6）的MBPU水平升高率高于平和体质组，但电针中脘（CV 12）20分钟后差异无统计学意义（均P>0.05）。
结论
阳虚体质志愿者任脉的能量代谢下降，尤其是膻中（CV 17）。电针可通过调节经络沿线的MBPU提高平和或阳虚体质志愿者任脉的能量代谢。
