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.

To surmount the obstacles of traditional Fenton method and synchronously utilize Cu^(2+)and polyphenol in water,an improved Fenton-like reaction applying calcium peroxide(CaO_(2))as H_(2)O_(2)source and regulating by the complex of Cu^(2+)-tartaric acid(TA,a representative of polyphenol)was constructed.A typical antibiotic,metronidazole(MTZ)could be effectively eliminated by the Cu^(2+)/TA/CaO_(2)system,and the optimized parameters were as follows:0.1 mmol/L Cu^(2+),2 mmol/L TA,2 mmol/L CaO_(2),and initial *** spectrum confirmed the formation of Cu^(2+)-TA complex,which promoted the Cu^(2+)/Cu+circulation through decreasing the Cu^(2+)/Cu^(+) couple redox potential,which further enhanced the H_(2)O_(2)decomposition and the formation of reactive *** radical was dominant for MTZ degradation,followed by oxygen and superoxide *** degradation intermediates of MTZ were detected and their evolution way was ***,the ternary process showed a wide p H tolerance(3–8)for removing MTZ and broad applicability for eliminating other dyes and *** work provided a reference for Cu-based Fenton-like strategy for organic wastewater settlement.
