Obesity has become a major global public health issue,and the situation in China is also becoming increasingly severe.Adipose tissue is categorized into white adipose tissue(WAT)and brown adipose tissue(BAT),which regulates metabolic homeostasis by secreting various adipokines.Mitochondria,as the core organelles of energy metabolism,its dysfunction are closely related to obesity.In the state of obesity,mitochondrial dynamics imbalance,oxidative stress,and metabolic dysfunction can all lead to energy metabolism disorders and adipose tissue dysfunction.Moreover,mitochondrial dysfunction not only affects adipose tissue but also extends to multiple organs such as muscles and livers,thereby exacerbating obesity and related metabolic diseases.In recent years,although numerous therapeutic strategies targeting mitochondrial dysfunction have been actively explored,their clinical translation faces challenges.This review explores the association between mitochondrial dysfunction in adipose tissue and obesity,analyses its mechanism and existing treatment strategies,aiming to provide a new perspective for the diagnosis and treatment of obesity.

Alcoholic liver disease (ALD) is a common cause of liver dysfunction and death due to liver-related diseases, which brings great harm to human health and social development. Many factors are involved in the development and progression of ALD, such as oxidative stress, change in gut microbiota, genetic variation, autophagy inhibition, and microRNAs. This article summarizes the mechanism of action of these factors in ALD, in order to provide a basis for the treatment of ALD and the discovery of new drug targets.
