人体穴位伏安特性研究

目的：研究人体穴位伏安特性的基本特征及随生理、病理变化出现的改变，探讨其生物物理学基础。方法：对本研究组近10年来有关穴位伏安特性研究工作进行整理分析。结果：人体穴位伏安特性曲线具有非线性、惯性两大特征。与对照点比较，穴位低电阻特征并非普遍存在，而低惯性特征则较具普遍性。穴位伏安面积不具有明显的昼夜节律而大部分穴位的惯性面积则具显著的昼夜节律性，其峰值相位和体温节律的谷值相位相应。心脏病患者和胃病患者穴位伏安特性发生了显著变化，这种变化具有一定的穴位特异性，病变缓解后穴位伏安特性也恢复正常。尸体穴位伏安面积和惯性面积均明显小于正常人，正常人穴位所具有的非线性和惯性特征在尸体上消失。结论：人体穴位具有非线性、惯性两大特征，穴位非线性特征反映了人体作为高等生物所具有的生理与行为的复杂性，而惯性特征则与穴位能量代谢有关。穴位惯性面积比伏安面积更能敏感地反映人体生理病理变化，应是今后穴位电学特性研究的重要指标。

Study on Volt-ampere (V-A) characteristics of human acupoints

OBJECTIVE: To study on basic Volt-ampere (V-A) characteristics of human acupoints and the changes with physiologic and pathologic changes, and probe their biophysical basis. METHODS: The research works of this research group about V-A characteristics of acupoints in recent 10 years were systematized and analyzed. RESULTS: V-A characteristic curve of human acupoints is of the both characteristics of non-linear and inertia. Compared with controlled point, the lower electric resistance characteristic of acupoints is not popular and the lower inertia is popular. V-A area of acupoints has no obvious circadian rhythms and the inertia area of a large part of acupoints has obvious circadian rhythms, with the phase of peak value corresponding to the phase of valley value of body temperature rhythms. V-A characteristics of acupoints in the patients of heart disease or stomach diseases changes obviously, and these changes have a certain specificities of acupoints. After remission of the lesion, the V-A characteristics of acupoints restore normal. The V-A area and the inertia area of acupoints in the corpse are obviously smaller than the normal person, with disappearance of the characteristics of both the non-linear and inertia of the normal person. CONCLUSION: Human acupoints have characteristics of non-linear and inertia, and the non-linear characteristic reflects complexity of physiology and behavior, while the inertia characteristic is related with energy metabolism of acupoints. The inertia area can more sensitively reflect human physiologic and pathological changes as compared with the V-A area, so it is an important index for the studies on electric characteristics of acupoints in the future.
