To observe the changes of volt-ampere characteristics of Yuan-Primary acupoints in women before, during and after menstruation, and to find out the relationships between Qi-blood in human body and volt-ampere characteristics of acupoints, so as to develop a new method for quantitative analysis on changes of Qi-blood.
A high-sensitive detection system of volt-ampere characteristics of acupoint was applied to detecting the volt-ampere characteristics of Taiyuan (LU 9), Daling (PC 7) and Shenmen (HT 7) in healthy women before, during and after menstruation.
The resistances on LU 9, PC 7 and HT 7 with some certain scan currents were quite different among the women before, during and after menstruation. For such changes, PC 7 was of the most obvious change, LU 9 was of the less and HT 7 was of the least. The total ratio of the scanning spots with significantly increasing changes of resistances on these three acupoints along with the menstrual process was 70.6%.
The volt-ampere characteristics of acupoints vary with the menstrual process, which is of the acupoint specificity. The resistances on the acupoints increase with the menstrual process, and such results may be due to the blood loss during menstruation. The volt-ampere characteristics can be used as a quantitative index to study on the change of Qi and blood.
观察女性月经前、经期、月经后原穴伏安特性的变化，探寻人体气血与穴位伏安特性之间的关系，以建立气血变化定量分析的新方法。
采用高灵敏度穴位伏安特性检测系统，检测健康女性月经前、经期、月经后太渊（LU 9）、大陵（PC 7）、神门（HT 7）的伏安特性。
在一定扫描电流下，LU 9、PC 7、HT 7在月经前、经期、月经后女性中的电阻有较大差异。其中PC 7变化最明显，LU 9次之，HT 7最小。这三个穴位电阻随月经进程显著升高的扫描点总比例为70.6%。
穴位伏安特性随月经进程变化，具有穴位特异性。穴位电阻随月经进程升高，其原因可能与经期失血有关。伏安特性可作为研究气血变化的定量指标。
