[Changes of microcirculation in superficial tissues of acupoint regions of lower leg during menstrual cycle in healthy young girls].

Objective: To observe changes of microcirculation in the superficial regions of acupoints of the three Yin meridians of foot during the menstrual cycle in young college students, so as to provide experimental evidence for explaining the saying of traditional Chinese medicine that acupoints reflect the state of physiological and pathological activities of the internal organs.

Methods: Ninety healthy female volunteer college students were recruited in the present study. The subjects were asked to take a supine position on an examination couch to expose the Yuan-primary acupoints Taixi (KI3), Taibai (SP3) and Taichong (LR3), and Xi-cleft acupoints Shuiquan (KI5), Diji (SP8) and Zhongdu (LR6) which are related to the uterus of the three Yin meridians of foot， the crossing acupoints of the three Yin meridians of foot Sanyinjiao (SP6), non-specific acupoint of the Spleen meridian Xuehai (SP10), non-related meridian acupoint Xuanzhong (GB39) and non-meridian-non-acupoint (being at the same level of GB39, between the Stomach and Gallbladder meridians on the lateral aspect of the lower leg).
