Patency and factors related to patency after percutaneous transluminal angioplasty for inflow arterial stenosis in native arteriovenous fistula dysfunction: a single-center retrospective study.

Controversy still exists regarding how much the inflow arterial percutaneous transluminal angioplasty (PTA) contributed to maintaining fistula function for hemodialysis. We aimed to analyze patency and risk factors after inflow arterial PTA. Hemodialysis patients with inflow arterial primary stenosis who were admitted to our institution from January 2017 to December 2022 were examined.

The association of metabolic dysfunction-associated steatotic liver disease (MASLD) with the risk of myocardial infarction: a systematic review and meta-analysis.

While studies have documented how metabolic dysfunction-associated steatotic liver disease (MASLD) can contribute to cardiovascular disease (CVD), whether MASLD is associated with myocardial infarction (MI) remains debateable. Herein, we systematically reviewed published articles and performed a meta-analysis to determine the relationship between MASLD and MI risk. PubMed, MEDLINE, Embase, Web of Science, CNKI, CBM, VIP, and WanFang databases were searched, and the DerSimonian Laird method was used to obtain hazard ratios (HRs) for binary variables to assess the correlation between MASLD and MI risk.

Random and aligned electrostatically spun PLLA nanofibrous membranes enhance bone repair in mouse femur midshaft defects.

Long-segment bone defects are a common clinical challenge and abstract biomaterials are a promising therapy. Poly-L-lactic acid (PLLA) nanofibrous membranes prepared by electrostatic spinning have a good bone repair potential. However, there are random and aligned surface morphologies of electrostatic spun PLLA nanofibrous membranes, which can affect the migration, proliferation, and differentiation ability of cells.

Stiff and strong hydrogel tube with great mechanical properties and high stability in various solutions.

Hydrogel tubes are widely used in fields such as artificial blood vessels, drug delivery, biomedical scaffolds and cell adhesion, yet their application is often limited by unsatisfactory mechanical properties and poor stability in various solutions. Herein, a novel hydrogel tube exhibiting a remarkable mechanical performance and stability in various solutions is prepared by introducing a dual physically cross-linked double network (DN) hydrogel matrix. The obtained hydrogel tube can withstand ∼60 N load without fracture and be stretched to over twice its original length before and after immersing in various solutions.

Fully physically cross-linked double network hydrogels with strong mechanical properties, good recovery and self-healing properties.

Combining a hydrophobic interaction crosslinked curdlan as the first network and hydrophobic interaction crosslinked polyacrylamide as the second network, we have fabricated a curdlan/HPAAm double network (DN) hydrogel using a one-pot method. The resulting DN hydrogel exhibited good mechanical properties, i.e.

Bisphenol A promotes hepatic lipid deposition involving Kupffer cells M1 polarization in male mice.

Bisphenol A (BPA), one of the most common environmental endocrine disruptors, is considered to promote hepatic lipid deposition. However, the mechanism has not been fully elucidated. The polarization of Kupffer cells (KCs) plays an important role in hepatic inflammation by promoting pro-inflammatory M1 phenotype (M1KCs), which contributes to dysregulated lipid metabolism.

AMP-kinase pathway is involved in tumor necrosis factor alpha-induced lipid accumulation in human hepatoma cells.

Aim: It is well known that lipid accumulation and inflammation are two important steps in pathogenesis and progress of nonalcoholic fatty liver disease (NAFLD). However, fewer studies have explored the direct relationship between lipid accumulation and inflammation in early NAFLD. Tumor necrosis factor alpha (TNF-α) is one of the classical inflammatory cytokines.

Lipopolysaccharide-binding protein cannot independently predict type 2 diabetes mellitus: A nested case-control study.

Background: Cross-sectional studies have reported a close association between serum lipopolysaccharide-binding protein (LBP) and many metabolic disorders. However, no longitudinal study has explored the relationship between LBP and type 2 diabetes mellitus (T2DM). The aim of the present study was to investigate the association between serum LBP levels and the risk of developing T2DM.

Rosiglitazone inhibits expression and secretion of PEDF in adipose tissue and liver of male SD rats via a PPAR-γ independent mechanism.

Pigment epithelium-derived factor (PEDF) plays an important role in insulin resistance (IR). The study aims to investigate the effect of rosiglitazone, an insulin sensitizer, on PEDF production and release both in vivo and in vitro. Male SD rats were divided into normal control group, high-fat group, and rosiglitazone group.

Metformin inhibits expression and secretion of PEDF in adipocyte and hepatocyte via promoting AMPK phosphorylation.

Objective: Pigment epithelium-derived factor (PEDF) plays an important role in obesity-induced insulin resistance (IR). The study aims to investigate the effect of metformin, a widely used agent to improve IR, on PEDF production both in vivo and in vitro.

Methods: SD rats were divided into normal control group, high fat group (HF group), and metformin group (MET group).

Efficacy and tolerability of febuxostat in hyperuricemic patients with or without gout: a systematic review and meta-analysis.

Background: Febuxostat has been approved for the treatment of hyperuricemia in patients with/without gout.

Objectives: This meta-analysis and systematic review assessed the efficacy and tolerability of febuxostat in hyperuricemic patients with/without gout.

Methods: Major electronic databases were searched for articles of all publication years (up to February 2012), as were the Web sites of the American College of Rheumatology, the European League Against Rheumatism, and the Chinese State Food and Drug Administration, and clinicaltrials.
