ABSTRACT

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). The laser speckle blood flow imaging technique was used to detect the state of microcirculation (average blood perfusion volume) during menstrual, follicular, ovulatory and luteal phases.

RESULTS:

The average blood perfusion volume (ABPV) of the right SP8 region was significantly lower in the menstrual phase than in the ovulation and luteal phases (P<0.05), and in the follicular phase than in the ovulation phase (P<0.05). In the left LR6 region, the ABPV was obviously lower in the menstrual period than in the follicular, ovulation and luteal phases (P<0.05). In the SP8, SP6, KI3 and KI5 regions, the ABPV was significantly higher in each of the 4 phases on the left side than on the right side (P<0.05). In the right GB39, the ABPV in each of the 4 phases was apparently higher on the right side than on the left side (P<0.05). In the SP10 region, the ABPV was considerably higher on the left side than on the right side in the ovulation period (P<0.05). The ABPV of SP3 in the menstrual phase and that of the non-acupoint in the luteal phase were significantly higher on the right side than on the left side (P<0.05).

CONCLUSION:

The blood perfusion of microcirculation in the superficial tissues of Xi-cleft acupoints SP8 and LR6 is obviously lower in the menstrual phase than in both of the ovulation and luteal phases in healthy young college students, which may specifically reflect the periodical activities of the uterus in the physiological state, and provide a basis of acupoint selection for menstrual healthy care.
