The studying on interrelation and interaction among blood-vessel network, nerve network and immune network is considered to be the key to reveal the mechanism of acupuncture treatment and the essence of meridians. A strip-like compound structure of mast cells, blood vessel and nerve network is observed in acupoint area. From its systematics nature and correlation with acupuncture effect and meridian phenomena, it is believed that the structure of mast cells, blood vessel and nerve network is an interactive system with interrelation and interaction among each other, and is an essential site and pivot to produce and transport matter, energy and information, and is the core structure of acupoint.

Anything in the universe can be explained by Yin-yang theory of Chinese medicine. Synaptic connections in the central nervous system also embody a balance between Yin and Yang. To discover the synaptic processes of gathering,storing and retrieving information in the brain is a hotspot field of modem neuroscience. This paper attempts to analyze the synaptic connection in both structure and function from Yin-Yang theory. The connections of axons and dendrites between neurons arc malleable and constantly changing, showing a Yin-Yang balance anatomically. Remodeling, stabilization and plasticity changes of synaptic processes also embody the relationship of contradictions, conflicts and transformation of Yin-Yang functionally. Therefore, it is possible to achieve an unexpected result to solve some modem medical problems by using the thoughts and methods of Chinese medicine.
