Study on the acupoints belonging to the three yin meridians of foot reflecting the variation pattern of uterine qi and blood in women with moderate constitution

Abstract

Objective

To observe the blood perfusion volume variation pattern in the body surface microcirculation at the Yuan-Primary and the Xi-Cleft points during the menstrual cycle in female college students with moderate constitution under normal physiological state of the uterus; to explore the specific laws of the body surface microcirculation at the Yuan-Primary and Xi-Cleft points in response to the uterine qi and blood changes under normal physiological conditions, and to provide the experimental basis for the specificity of acupoints reflecting the uterine function.

Methods

Forty-three healthy and moderate constitution female college students with regular menstrual cycles, without dysmenorrhea and not yet giving birth were recruited. Bilateral Yuan-Primary points [Taichong (LR 3), Taibai (SP 3) and Taixi (KI 3)] and Xi-Cleft points [Zhongdu (LR 6), Diji (SP 8) and Shuiquan (KI 5)], belonging to the three yin meridians of foot and adjacent to the spinal cord segment of the uterus, were selected as the detection acupoints; the crossing point of the three yin meridians of foot [Sanyinjiao (SP 6)], the uterus-related meridian acupoint [Xuehai (SP 10)], the uterus-non-related meridian acupoint [Xuanzhong (GB 39)], and the non-meridian non-acupoint point were selected as the control points. The laser speckle blood flow imaging technique was used to monitor the blood perfusion volume in skin microcirculation at the above points at the menstrual, follicular, ovulatory, and luteal phases of the subjects.

Results

The blood perfusion volume in the body surface microcirculation at the right Zhongdu (LR 6) at the ovulatory phase was higher than that at the menstrual, follicular and luteal phases (all P<0.05); there was no significant difference in the microcirculation blood perfusion volume at the other points among different phases (all P<0.05).

Conclusion

The blood perfusion volume in the body surface microcirculation at Zhongdu (LR 6), the Xi-Cleft point of the Liver Meridian, shows a specific response to qi and blood changes in the uterus of women with moderate constitution.

摘要

目的:观察胞宫正常生理状态下平和体质女大学生足三阴经原穴和郄穴体表微循环血流灌注量在月经周 期中的变化特点, 探求生理状态下原穴和郄穴体表微循环反应胞宫气血变化的特异性规律, 为经穴反应功能特 异性提供实验依据。方法:在校招募43名月经周期规律、无痛经且体质类型为平和体质的健康未育女大学生, 选 择与胞宫位于邻近脊髓节段的足三阴经的双侧原穴(太冲、太白和太溪)和郄穴(中都、地机和水泉)作为探测点, 选 取足三阴经交会穴(三阴交)、胞宫相关经穴(血海)、胞宫非相关经穴(悬钟)以及非经非穴点作为对照点。利用激光 散斑血流成像技术分别在受试者月经期、卵泡期、排卵期和黄体期监测上述监测点的皮肤微循环血流灌注量。 结果:右侧中都穴排卵期体表微循环血流灌注量高于月经期、卵泡期和黄体期(P<0.05); 其余穴位各时期微循环 血流灌注量比较无显著性差异(P<0.05)。结论:肝经郄穴中都穴体表微循环血流灌注量具有反应平和体质女性胞 宫气血变化的特异性。
