Impact of Lycium barbarum polysaccharide on the expression of glucagon-like peptide 1 in vitro and in vivo.

Several studies showed the efficacy of Lycium barbarum polysaccharide (LBP) in diabetic animals and patients with type 2 diabetes mellitus (T2DM). However, the mechanism of LBP in alleviating T2DM based on glucagon-like peptide 1 (GLP1) has not been suitably elucidated. GLP1 is an important peptide that plays a role in blood glucose homeostasis.

Effects of cubic ecological restoration of mining wasteland and the preferred restoration scheme.

In view of the strong acidity and high heavy metal contents of the soil, the low vegetation cover, and strong soil erosion caused by mining activities, the reasonable determination of the cubic restoration mode is the key to determining the good or bad ecological restoration effects on mining wasteland. In this study, based on field experiments, a combined cubic ecological restoration scheme for soil improvement-vegetation reconstruction was constructed. Using analysis of variance, a regression model, and the Mantel test, the differences in soil properties and the biodiversity were analyzed under different restoration schemes, the entropy-weighted-TOPSIS method was used to optimize the best ecological restoration model.

A redox-active support for the synthesis of Au@SnO core-shell nanostructure and SnO quantum dots with efficient photoactivities.

A defect pyrochlore-type SnNbOF (SnNbOF) nano-octahedron is used as a redox-active support for fabricating Au@SnO core-shell and SnO quantum dots at room temperature without the use of organic species or foreign reducing reagents. Gold (Au) and SnO components were obtained through an redox reaction between the HAuCl and reductive Sn ions incorporated in SnNbOF. The composition and morphology of the resulting nanocomposites (denoted as Au-SnNbOF) could be controlled by adjusting the Au/SnNbOF ratio.

[TLR/NF-κB independent signaling pathway in TNF-α suppression of diabetic MyD88-knockout mice after polysaccharides administration].

Objective: : To investigate the effect of polysaccharides (LBPs) on TLR/NF-κB independent pathway and serum tumor necrosis factor (TNF-α) level in diabetic MyD88-knockout mice.

Methods: : Diabetes was induced by feeding high-fat/high-sugar diet and injection of low-dose streptozotocin in MyD88-knockout mice. The diabetic mice were randomly divided into model group, positive control group and LBPs group.

Effects of a liquid high-fat meal on postprandial lipid metabolism in type 2 diabetic patients with abdominal obesity.

Background: Postprandial lipemia and lipoprotein lipase (LPL) activity play crucial roles in the pathogenesis of accelerated atherosclerosis. This study aimed to evaluate the postprandial lipid metabolism after the ingestion of a liquid high-fat meal in type 2 diabetic patients with abdominal obesity, and determine if the PvuII polymorphisms of LPL influence their postprandial lipid responses.

Methods: Serum glucose, insulin, triglycerides (TG), total cholesterol (TC) and high density lipoprotein cholesterol (HDL-C) were measured in fasting and postprandial state at 0.

Consumption of a liquid high-fat meal increases triglycerides but decreases high-density lipoprotein cholesterol in abdominally obese subjects with high postprandial insulin resistance.

Abdominal obesity is associated with an increased risk of insulin resistance, which may be a potential contributor to dyslipidemia. However, the relationship between postprandial insulin resistance and lipid metabolism in abdominally obese subjects remains unknown. We hypothesized that postprandial dyslipidemia would be exaggerated in abdominally obese subjects with high postprandial insulin resistance.

The effects of Lycium barbarum L. (L. barbarum) on cardiometabolic risk factors: a meta-analysis of randomized controlled trials.

The effects of Lycium barbarum L. (L. barbarum) on the cardiometabolic risk factors from randomized controlled trials (RCTs) have shown inconsistent results.

Lycium barbarum L. Polysaccharide (LBP) Reduces Glucose Uptake via Down-Regulation of SGLT-1 in Caco2 Cell.

L. polysaccharide (LBP) is prepared from L. (), which is a traditional Chinese medicine.

Melanocortin-4 receptor rs17782313 polymorphisms are associated with serum triglycerides in older Chinese women.

Background And Objectives: MC4R (melanocortin-4 receptor) gene polymorphisms have been associated with serum triglycerides (TG) in Caucasians and Japanese, but no reports are available Chinese. The purpose of this study was to find whether there was an association of rs17782313 polymorphisms at the MC4R gene with serum TG in elderly Chinese.

Methods And Study Design: 2,012 over 40 years participated in a cross-sectional study in which their body mass index (BMI), TG, high density lipoprotein-cholesterol (HDL-C), and MC4R rs17782313 polymorphisms were determined.

Wheat peptides reduce oxidative stress and inhibit NO production through modulating μ-opioid receptor in a rat NSAID-induced stomach damage model.

Non-steroidal anti-inflammatory drugs (NSAIDs) induce tissue damage and oxidative stress in animal models of stomach damage. In the present study, the protective effects of wheat peptides were evaluated in a NSAID-induced stomach damage model in rats. Different doses of wheat peptides or distilled water were administered daily by gavage for 30 days before the rat stomach damage model was established by administration of NSAIDs (aspirin and indomethacin) into the digestive tract twice.

Practical Application of Antidiabetic Efficacy of Lycium barbarum Polysaccharide in Patients with Type 2 Diabetes.

Lycium barbarum polysaccharide (LBP) has traditionally been used in Chinese medicine as a chief ingredient of Lycium barbarum (wolf berry/goji berry) for the treatment of various diseases with the symptoms of frequent drinking and urination. This study was conducted as a randomized, controlled clinical trial. A total of 67 patients with type 2 diabetes (30 in control group and 37 in LBP group) were enrolled in this prospective, randomized, double-blind study (administration at 300 mg/day body weight).
