Abstract：This article systematically analyzes the scientific connotations of Sanjiao qi transformation and water channels functions,clarifies their intrinsic connection with the meridian system and the regulation mechanism of acupuncture.It is proposed that Sanjiao is a unique system in the theory of Zangxiang in traditional Chinese medicine,constructs the macroscopic architecture of human life activities through the spatial compartmentalization of"three regions"and the physiological operation of"two functions".In terms of spatial distribution,Sanjiao are vertically arranged as the upper jiao being like mist(dispersing and diffusing),the middle jiao being like fermentation(digesting and ripening),and the lower jiao being like a ditch(excreting).Functionally,their dual roles of"transporting the primordial qi"(qi transformation)and"circulating body fluids"(water channels)correspond respectively to the physiological mechanisms of energy and material metabolism and body fluid distribution in Western medicine.Sanjiao and the meridian system are interdependent and complementary,jointly facilitating the circulation and distribution of qi,blood and body fluids.From the perspective of modern biomedicine,the macroscopic functions of Sanjiao can be mapped to the neuro-metabolism-immune network.Acupuncture exerts a therapeutic effect of"regulating the pivot to facilitate functional activities"by modulating key nodes within this net-work(such as nerve conduction,mitochondrial energy conversion and immune cell polarization).
