Résumé
Through the systematic analysis on the primo vascular system (PVS) in recent years, we believe that in recent years, more and more studies have indicated that PVS is distributed in reticulate structure in every part of body, such as vessels, lymphangions, nerves, brain, spinal cords and internal organs, and it contains a large amount of immunocytes and has involved in the physiological or pathological process of the immunity and circulation in the body. There are the evidences to prove that in morphology and cytobiology. But, nowadays, there is no way to explain its effect characters. On the basis of the study on living matter characteristics, a breakthrough is possibly made through the systematic cooperation even though it is the difficulty to detect the life function effect. It is especially displayed in the substantial study on meridian points. Hence, the study on the law of meridian point effects on the basis of clinical practice has to be focused on in the substantial study on meridian points.
