Abstract:The core connotation of circular flow of original qi refers to the yin-yang pattern of qi movement:the mediation of "earth qi in the middle energizer,the ascending and dispersing of wood and water on the left pivot,and the descending and astringing of fire and metal on the right pivot." The core pathogenesis of cardiovascular-kidneymetabolic syndrome (CKMS) consists in the dysfunction of transportation and transformation of the spleen and stomach, and the weakened pivot function of earth qi,which results in the obstruction of circular flow of original qi,dysfunction of the liver,heart,lung,and kidney,and further induces pathological changes such as phlegm turbidity,dampness stagnation, and blood stasis. Dysfunction of the spleen and stomach is the initiating pathogenic factor; failure of the liver in free coursing is an important driver of disease progression; insufficient heart yang and impaired storage and consolidation of the kidney are the fundamental root causes;and disordered diffusion and descent of the lung acts as a synergistic influencing factor. On this basis, the therapeutic principles are formulated, including strengthening and regulating the middle energizer,soothing liver qi,warming and unblocking heart yang,tonifying kidney essence,and regulating pulmonary diffusion and descent. It emphasizes holistic regulation and treatment based on syndrome differentiation. Restoring the normal operation of circular flow of original qi can achieve effective treatment of CKMS.
