摘要: 酮病是围产期奶牛糖脂代谢失衡而导致的一种营养代谢性疾病,主要表现为体内酮体的积累和游离性脂肪酸的升高,同时伴随血糖、胰岛素浓度异常和胰高血糖素浓度的升高。该病严重危害奶牛的健康和生产性能,给奶牛养殖业造成巨大损失。酮病发生的核心环节是糖脂代谢紊乱,生物钟作为哺乳动物重要的内源性稳态调控系统,可通过调节糖脂代谢相关激素分泌、限速酶基因与核受体基因的表达来调控机体糖脂代谢的昼夜节律稳态。笔者对奶牛酮病与糖脂代谢紊乱的联系、生物钟在哺乳动物糖脂代谢昼夜节律稳态调控中的作用、生物钟调控奶牛代谢生理的昼夜节律和酮病对奶牛糖脂代谢昼夜节律的影响进行了综述,以期从时间生物学的角度更全面地认识奶牛酮病的发病机制,为探究精准、高效的酮病防控与治疗策略提供新的思路。

Abstract: Ketosis is a nutritional metabolic disease caused by the imbalance of glucose and lipid metabolism in perinatal dairy cows.It is mainly manifested by the accumulation of ketone bodies and the increase of free fatty acids,accompanied by abnormal concentration of blood sugar,insulin and glucagon.The disease seriously endangers the health and production performance of dairy cows and causes huge losses to the dairy farming industry.The core link of ketosis is the disorder of glucose and lipid metabolism.As an important endogenous homeostasis regulation system in mammals,the circadian clock can regulate the circadian rhythm of glucose and lipid metabolism by regulating the secretion of hormones related to glucose and lipid metabolism,the expression of rate-limiting enzyme genes and nuclear receptor genes.This paper reviewed the connection between ketosis and glycolipid metabolism disorders in dairy cows,the role of the circadian clock in the regulation of circadian rhythm homeostasis of lipid and carbohydrate metabolism in mammals,the circadian rhythm of metabolic physiology regulated by circadian clock in dairy cows,and the effects of ketosis on the circadian rhythm of glucose and lipid metabolism in dairy cows,in order to understand the pathogenesis of ketosis in dairy cows more comprehensively from the perspective of chronobiology,and provide new ideas for exploring accurate and efficient prevention and treatment strategy of ketosis.

Key words: ketosis; circadian rhythm; glycolipid metabolism; regulation mechanism
