Analysis of long-term outcome of modified gastric bypass for type 2 diabetes mellitus in Chinese patients.

Background: Bariatric and metabolic surgery have been routinely performed following the rapid increase in obesity and metabolic diseases worldwide. Of all evolving procedures, Roux-en-Y gastric bypass (RYGB) is considered the gold standard for surgical treatment of patients with type 2 diabetes mellitus (T2DM) and obesity. RYGB was introduced in China nearly 20 years ago, but the number of RYGB surgeries only accounts for 3.

Modeling alcohol-associated liver disease in humans using adipose stromal or stem cell-derived organoids.

Alcohol-associated liver disease (ALD) is a prevalent liver disease, yet research is hampered by the lack of suitable and reliable human ALD models. Herein, we generated human adipose stromal/stem cell (hASC)-derived hepatocellular organoids (hAHOs) and hASC-derived liver organoids (hALOs) in a three-dimensional system using hASC-derived hepatocyte-like cells and endodermal progenitor cells, respectively. The hAHOs were composed of major hepatocytes and cholangiocytes.

Blockade of TGF-β signalling alleviates human adipose stem cell senescence induced by native ECM in obesity visceral white adipose tissue.

Background: Abdominal obesity is appreciated as a major player in insulin resistance and metabolically dysfunctional adipose tissue. Inappropriate extracellular matrix (ECM) remodelling and functional alterations in human adipose stromal/stem cells (hASCs) have been linked with visceral white adipose tissue (vWAT) dysfunction in obesity. Understanding the interactions between hASCs and the native ECM environment in obese vWAT is required for the development of future therapeutic approaches for obesity-associated metabolic complications.

Efficacy and safety of one anastomosis gastric bypass versus Roux-en-Y gastric bypass for type 2 diabetes remission (ORDER): protocol of a multicentre, randomised controlled, open-label, superiority trial.

Introduction: Previous studies have demonstrated that one anastomosis gastric bypass (OAGB) is not inferior to Roux-en-Y gastric bypass (RYGB) in treating obesity. However, high level evidence comparing the efficacy and safety of both procedures in type 2 diabetes (T2D) treatment is still lacking, which is another main aim of bariatric surgery. The presented trial has been designed to aim at investigating the superiority of OAGB over the reference procedure RYGB in treating T2D as primary endpoint.

Bariatric surgery for non-alcoholic fatty liver disease in individuals with obesity (Base-NAFLD): protocol of a prospective multicenter observational follow-up study.

Background: Bariatric surgery may be indicated in patients with nonalcoholic fatty liver disease (NAFLD) to achieve and maintain the degree of weight loss required to ensure therapeutic effects. However, bariatric surgery is still underrecognized in the treatment of NAFLD, including its inflammatory subtype, nonalcoholic steatohepatitis (NASH). Moreover, there is a lack of follow-up outcome data on different types of bariatric surgery in patients with NAFLD.

The Choice of Gastric Bypass or Sleeve Gastrectomy for Patients Stratified by Diabetes Duration and Body Mass Index (BMI) level: Results from a National Registry and Meta-analysis.

Purpose: To determine whether sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) should be the optimal choice in patients stratified by diabetes duration and body mass index (BMI) level.

Methods: Classification tree analysis was performed to identify the influential factors for surgical procedure selection in real setting. Meta-analyses stratified by influential factors were conducted to compare the complete diabetes remission rates between SG and RYGB.

GSK3 inhibitor ameliorates steatosis through the modulation of mitochondrial dysfunction in hepatocytes of obese patients.

Obesity is an important risk factor and a potential treatment target for hepatic steatosis. The maladaptation of hepatic mitochondrial flexibility plays a key role in the hepatic steatosis. Herein, we found that hepatocyte-like cells derived from human adipose stem cell of obese patients exhibited the characteristics of hepatic steatosis and accompanied with lower expression of the subunits of mitochondrial complex I and lower oxidative phosphorylation levels.

Prediction of Long-Term Diabetes Remission After Metabolic Surgery in Obese East Asian Patients: a Comparison Between ABCD and IMS Scores.

Purpose: Recently, more than 10 models have been developed to predict remission of type 2 diabetes mellitus (T2DM) after metabolic surgery. The ABCD score was compared to the individualized metabolic surgery (IMS) score in terms of prediction of T2DM remission, but which of the two scoring systems is better remains controversial.

Methods: Patient data from 463 obese East Asian patients who underwent laparoscopic Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG), or SG with duodenojejunal bypass (SG-DJB) as a primary operation and were followed for at least 3 years were retrospectively collected from 24 institutions.

Clinical Outcomes of One Anastomosis Gastric Bypass Versus Sleeve Gastrectomy for Morbid Obesity.

Background: One anastomosis gastric bypass (OAGB) and sleeve gastrectomy (SG) are popular bariatric surgeries for morbid obesity. Reports on the safety and effectiveness of SG and OAGB are inconsistent. This meta-analysis investigated the clinical outcomes of SG versus those of OAGB for morbid obesity.

MicroRNA-940 restricts the expression of metastasis-associated gene MACC1 and enhances the antitumor effect of Anlotinib on colorectal cancer.
