To investigate the specific regularity of body surface resistance at different acupoints of the meridians associated with the uterus in reflecting menstrual cycle by observing the change in body surface resistance at source points, cleft points, confluent points, and non-specific points of three meridians of the foot in different menstrual cycles in normal female college students, to lay a foundation for the in-depth research on the mechanism of acupoints reflecting the function of , and to provide a reference for the clinical and scientific research on the biophysical characteristics of menstrual cycle-related acupoints in normal female.
A total of 90 normal female college students were recruited. The source points, cleftpoints, confluent points, and non-specific points of three yin meridians of the foot which were located in the adjacent spinal segments of the uterus were selected, and body surface resistance was monitored for 30 consecutive minutes at the same time-points of menstrual phase, follicular phase, ovulation phase, and luteal phase to observe the change in the resistance of each acupoint during the menstrual cycle.
There was no significant change in the resistance value of unilateral acupoints during the menstrual cycle (>0.05). In the same period, there was no significant difference in resistance value between unilateral three source points, three cleftpoints, different acupoints of the spleen meridian, and different acupoints of lumbar 4 dermatomere (>0.05). As for the comparison of resistance of the same acupoint at the left and right sides, Taichong (LR3) at the left side had a higher resistance value than that at the right side in the menstrual phase (<0.05); Taibai (SP3) at the left side had a higher resistance value than that at the right side in the ovulation phase (<0.05); Zhongdu (LR6) at the left side had a higher resistance value than that at the right side in the follicular phase, the ovulation phase, and the luteal phase (<0.05); Taixi (KI3), Diji (SP8), and Sanyinjiao (SP6) at the left side had a higher resistance value than those at the right side in the menstrual phase, the follicular phase, the ovulation phase, and the luteal phase (<0.05); Shuiquan (KI5) at the left side had a lower resistance value than that at the right side in these four phases (<0.05).
The change trend of the resistance of the acupoints at the left and right sides associated with the three yin meridians of the foot can specifically reflect the change in qi and blood in the uterus during the menstrual cycle. The change trend of the source and cleft points of the liver meridian in the menstrual phase is different from that in the other phases, and the change trend of SP3, a source point of the spleen meridian, in the ovulation phase is different from that in the other phases, which suggests the specificity of meridian points in reflecting function. The mechanism by which meridian points reflect the function of zang-fu is associated with the meridian points and the spinal cord segments of , and meanwhile, it has a specific relationship with the meridians to which meridian points belong and the attributes of acupoints.
通过观察正常女大学生在不同月经周期中足三阴经原穴、络穴、交会穴及非特异性腧穴体表电阻的变化，探讨与子宫相关经脉不同腧穴体表电阻反映月经周期的具体规律，为深入研究腧穴反映脏腑功能的机制奠定基础，为正常女性月经周期相关腧穴生物物理特性的临床及科研提供参考。
选取90名正常女大学生。选取位于子宫相邻脊髓节段的足三阴经原穴、络穴、交会穴及非特异性腧穴，在月经周期的月经期、卵泡期、排卵期、黄体期的同一时间点连续监测30分钟体表电阻，观察各腧穴在月经周期中的电阻变化。
月经周期中单侧腧穴电阻值无明显变化（>0.05）。同期，单侧三阴经原穴、络穴、脾经不同腧穴及腰4皮节不同腧穴电阻值比较差异无统计学意义（>0.05）。左右侧同一腧穴电阻比较，左侧太冲（LR3）在月经期电阻值高于右侧（<0.05）；左侧太白（SP3）在排卵期电阻值高于右侧（<0.05）；左侧中都（LR6）在卵泡期、排卵期、黄体期电阻值高于右侧（<0.05）；左侧太溪（KI3）、地机（SP8）、三阴交（SP6）在月经期、卵泡期、排卵期、黄体期电阻值高于右侧（<0.05）；左侧水泉（KI5）在这四个时期电阻值低于右侧（<0.05）。
足三阴经左右侧相关腧穴电阻变化趋势可特异性反映月经周期中子宫气血的变化。肝经原穴、络穴在月经期的变化趋势与其他时期不同，脾经原穴SP3在排卵期的变化趋势与其他时期不同，提示经穴反映功能具有特异性。经穴反映脏腑功能的机制与经穴及相关脊髓节段有关，同时与经穴所属经脉及腧穴属性有特定关系。
