人体肢体结缔组织中组织液流动三维渗流动力学模型分析与针刺信号传递机理

On the base of deep part dissection of acupoints on the upper limbs of human body and the micro and macro observation and measurement, we constructed a mathematical model on the flow of the tissue fluid in interosseous membrane. By this model, we get to know the characteristics of the tissue-fluid flow and the influence of tissue-fluid flow on superficial shear stress of mast cell. The results of this study preliminarily explain the feeling-along-meridian phenomenon and the acupuncture mechanism. When being acupunctured, the related mast cells will be activated to discharge particles. The histamine in the particles will increase the transmission capacity of capillary and the velocity of the tissue-fluid flow and the superficial shear stress of related mast cell will be increased, which will once again activate mast cells to discharge active substance. Part of the active substance will be absorbed by capillary and the other part will be passed by tissue fluid to a remote place and it will activate the mast cells and the capillaries there. The directional path of the tissue fluid is approximately the same as the meridian, which forms the phenomenon of feeling-along-meridian on macroscale.
