Visceral adipose tissue predicts severity and prognosis of acute pancreatitis in obese patients

引用

Hepatobiliary & Pancreatic Diseases International 2024年第5期23卷 458-462页

作者： Yuan tian qing Huang Yu-Tang Ren Xuan Jiang Bo Jiang Department of Gastroenterology Beijing Tsinghua Changgung HospitalSchool of Clinical MedicineTsinghua UniversityBeijing 102218China

Acute pancreatitis is a common systemic inflammatory disease, manifested by a spectrum of severity, ranging from mild in the majority of patients to severe acute pancreatitis. Patients with severe acute pancreatitis suffer from severe local and systemic complications and organ failure, leading to a poor prognosis. The early recognition of the severe condition is important to improve prognosis. Obesity has risen in tandem with an increase in the severity of acute pancreatitis in recent years. Studies have revealed that adipose tissue, particularly visceral adipose tissue is associated with the prognosis of acute pancreatitis. This review discussed the role of visceral adipose tissue in obese patients with acute pancreatitis and explored the possible mechanism involved.

Lactic acid bacteria act as potent interventions in improving hyperuricemia: a review

引用

Food Science and Human Wellness 2024年

作者： qing-Ling Wu Xiao-Dong Pei tian-tian Gao Xiao-Ling liu Cheng-Hua Wang College of Light Industry and Food Engineering， Guangxi University

Hyperuricemia (HUA) is characterized by elevated levels of uric acid (UA) in the bloodstream， resulting from either excessive production or insufficient excretion of UA within the body. If left untreated， progressive or persistent HUA can lead to gout， causing significant harm to human health. Lactic acid bacteria (LAB)， generally recognized as safe (GRAS) probiotics， have been shown to alleviate symptoms associated with gastrointestinal disorders such as irritable bowel syndrome and inflammatory bowel disease while supporting overall bodily functions and health. Recently， LAB has emerged as a potentially safe， cost-effective and efficient treatment for HUA. This comprehensive review aims to explore the current literature on the mechanisms through which LAB controls HUA. These mechanisms include suppressing purine metabolism， absorbing purine compounds， modulating microbiota to maintain host global purine homeostasis， reducing intestinal permeability， producing metabolites that alleviate HUA symptoms， promoting the expression of urate excretory proteins and inhibiting the expression of urate reabsorption proteins. The findings presented in this review provide a framework for further investigation into how probiotic LAB can alleviate HUA by influencing UA metabolism and elucidating their underlying action mechanisms.
