Non-linear characteristic of acupoint resistance and its application / 中国针灸

Acupoint specificity is a key scientific issue in acupuncture and moxibustion. Acupoint electric resistance is a commonly-used biophysical index to study the functional specificity of acupoints. The non-linear characteristics of acupoint electric resistance have great impacts on the measured values, but it has been greatly ignored. By analyzing the non-linear characteristics of acupoint resistance and its application in the study of acupoint function specificity, a new idea of introducing chaos theory and technology into the study of acupoint function is proposed.

Investigation of pathway and mechanism of heat stimulating action of sandwiched moxibustion / 中国针灸

Based on the literature review and theories of biophysical theory, the pathway and mechanism of the heat of sandwiched moxibustion stimulating acupoints are analyzed. It is concluded that the heat of sandwiched moxibustion is transferred to the skin of acupoints by heat conduction and thermal radiation. The heat conduct from the skin to deep tissues and other parts was carried out through the biological heat conduction systems. The investigation combined with theories of biological heat conduction was benefit to the research on clinical mechanisms of indirect moxibustion. In addition to heat effect, the infrared resonance of indirect moxibustion and acupoints may be the base of clinical effects of indirect moxibustion.

Study on Volt-ampere (V-A) characteristics of human acupoints / 中国针灸

<p><b>OBJECTIVE</b>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.</p><p><b>METHODS</b>The research works of this research group about V-A characteristics of acupoints in recent 10 years were systematized and analyzed.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>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.</p>
