Both kidney fat and marrow are the essence of the kidney in the physiological state,the material basis of which is kidney water,and both are generated by the warming effect of the Xiang Huo,and both of them are closely related to the physiology and pathology of bone.Regarding the theory of 'kidney-essence-marrow-bone',the experts have reached a consensus:if the marrow is empty,the bone will not be firm,and tonifying the kidney and benefiting the marrow is the basic treatment for degenerative bone diseases.About kidney fat and bone,it has been recorded that:kidney fat drying will lead to bone marrow insufficiency,development of bone bi,etc.,and the pathogenesis can be divided into deficiency and excess.The deficiency mechanism is mainly due to the deficiency of yuanyang and the loss of warmth of kidney water,while the excess one is internal fire and dryness.The etiology of the disease may be related to external pathogenic fire-heat,excessive consumption of bitter and cold products,overexertion or loss of nourishment that leads to latent depletion of yin-blood,its clinical manifestations are mainly lumbar pain,clonus and so on.Modern literature research shows that kidney fat involved in the regulation of bone physiology and pathology may be related to the bone marrow mesenchymal stem cells in the marrow of the bone induced osteogenic differentiation,and it may be under the influence of tiangui,but its specific mechanism of action and the law still need to be further excavated and explored.
