摘要: 【摘要】肌肉萎缩是慢性肾脏病(chronic kidney disease,CKD)中后期常见的并发症,主要表现为肌肉质量减轻、肌肉力量降低、肌肉功能减退等。肌肉蛋白降解的增加是肌肉萎缩的主要原因,CKD 患者体内有毒代谢产物的累积、血浆pH 值的降低等病理状态能够激发肌肉的蛋白质降解途径从而导致肌肉萎缩。本文将从尿毒症毒素、代谢性酸中毒、炎症、激素和肠道菌群5 个方面对CKD 肌肉萎缩机制的研究进展进行综述。

Abstract: 【Abstract】Muscle atrophy is a common complication in the middle and late stage of chronic kidney disease (CKD), which mainly manifested as decreased muscle mass, decreased muscle strength, and decreased muscle function. The main cause of muscle atrophy is the enhancement of muscle protein degradation. The muscle protein degradation pathway can be stimulated by CKD pathological conditions such as the accumulation of toxic metabolites and the decrease of plasma pH value, then lead to muscle atrophy. This paper reviewed the research progress of muscle atrophy in CKD from the following five aspects: uremia toxin, metabolic acidosis, inflammation, hormones and intestinal flora.

Key words: Chronic kidney diseases, Muscular dystrophy, Signal pathway
