To the Editor: Obesity and type 2 diabetes (T2D) present significant health issues in China. Despite generally having lower body mass index (BMI) thresholds than Western populations, Chinese individuals often experience higher rates of central obesity, leading to increased metabolic risks even at BMI levels. The prevalence T2D among adults China is estimated be 11.2%. Traditional treatments, including lifestyle interventions medications, fail achieve sustained weight loss effective glycemic...

Introduction: As the most common postoperative complication, intestinal adhesions can cause obstruction, female infertility, and even endanger life. The currently developed materials for preventing mainly focus on physical barriers reducing inflammatory reactions, while neglecting importance of effectively promoting rapid repair peritoneum. We previously found that platelet-rich fibrin (PRF) prevent adhesions. proliferation mesothelial cells may play a significant role in adhesions, but...

Abstract Background and Aim To identify individuals with metabolic dysfunction‐associated steatohepatitis (MASH) or “at‐risk” MASH among patients steatotic liver disease (MASLD), three noninvasive models are available satisfactory efficiency, which include magnetic resonance imaging [MRI]‐ AST (MAST), FibroScan‐AST (FAST score), elastography [MRE] plus FIB‐4 (MEFIB). We aimed to evaluate the most accurate approach for diagnosing MASH. Methods included 108 biopsy‐proven MASLD who underwent...
