Abstract:Abstract: Metabolic syndrome kidney damage is a renal dysfunction caused by the long-term abnormal accumulation and deposition of various harmful metabolic substances, and energy metabolism disorders are an important cause of its onset. The theory of “Qi returns to essence, essence returns to transformation” reflects the process of mutual conversion between matter and energy. The discrete release of energy from matter is called “Qi returns to essence” , and the aggregation of energy into biomass is called “essence returns to transformation” . On the other hand, it refers to the spleen and stomach converting the fine substances in the ingested food into acquired essence, which is gradually transported to the human body through the spleen and stomach to maintain the basic life activities of the body. Its connotation is to care for the spleen and stomach, maintain good spleen and stomach health, and activate blood biochemistry in the future. When Qi and blood are sufficient, kidney qi can be filled. When the temperament is full, clear yang can rise and turbid evil can be eliminated, which is consistent with the pathogenesis and main treatment direction of metabolic syndrome kidney damage.
