基于“脾主运化,在体合肌”理论探析T2DM肌少症骨骼肌细胞铁死亡发病机制及辨证论治

Discussion on Pathogenesis of Skeletal Muscle Cell Ferroptosis and Syndrome Differentiation and Treatment of Type 2 Diabetes Mellitus Sarcopenia Based on"Spleen Governing Transportation and Transportation and Governing Muscle"

2型糖尿病(Type 2 diabetes mellitus,T2DM)伴随的衰老性疾病是目前糖尿病领域研究热点,肌少症现已成为T2DM继微血管和大血管病变之外的第三大类并发症,能够导致骨折、失能、活动障碍等多种不良事件的发生发展。脾属土,居中焦,主运化,在体合肌。脾之健运、精气得布、肌肉充养,方可发挥正常生理功能。近年研究表明,骨骼肌细胞铁死亡在T2DM肌少症发病机制中具有重要作用。基于“脾主运化,在体合肌”理论,从中医学“脾失运化、精气亏虚、湿浊困阻、肌肉失养”病机观及现代医学“骨骼肌细胞铁死亡”病理机制的角度对T2DM肌少症发病机制进行探讨,归纳T2DM肌少症从脾论治的中医防治原则,为丰富脾藏象理论内涵以及中医药防治T2DM肌少症基础研究和临床试验提供理论支撑。

The aging disease associated with type 2 diabetes mellitus(T2DM)is a hot research topic in the field of diabetes at present.Sarcopenia has become the third major complication of T2DM after microvascular and macrovascular diseases,which could lead to the occurrence and development of various adverse events such as fracture,disability,and dysfunction.The spleen belongs to the earth,is in the middle jiao,governs transportation and transformation,and governs muscle.The functional activities of the spleen manifesting in normal transformation and transportation,the distribution of cereal essence,and the nourishment of muscles are necessary for normal physiological functions to be exerted.Recent studies have shown that skeletal muscle cell ferroptosis plays an important role in the pathogenesis of T2DM sarcopenia.Based on the theory of"spleen governing transportation and transportation and governing muscle",this study explores the pathogenesis of T2DM sarcopenia from the perspectives of the pathogenesis of"dysfunction of spleen in transportation,deficiency of cereal essence,obstruction of dampness and turbidity,and muscle dystrophy"in traditional Chinese medicine and the pathological mechanism of"skeletal muscle cell ferroptosis"in modern medicine.It summarizes the principles of traditional Chinese medicine prevention and treatment for T2DM sarcopenia based on the spleen,to provide theoretical support for enriching the theoretical connotation of spleen visceral state,as well as basic research and clinical trials on the prevention and treatment of T2DM sarcopenia with traditional Chinese medicine.
