Glycemic variability (GV) may be linked to the development of diabetic complications by inducing inflammation, oxidative stress, and endothelial dysfunction. Flash glucose monitoring (FGM) provides a novel method of continuously monitoring interstitial glucose levels for up to 14 days. This study randomly assigned poorly controlled type 2 diabetes mellitus patients treated with metformin and multiple daily injections of insulin (n=60) to either continuous subcutaneous insulin infusion (CSII) treatment or CSII in combination with liraglutide (CSII+Lira) treatment for 14 days during hospitalization.

Background: This study aimed to investigate roles of Toll-like receptor 4 (TLR4)/nuclear factor (NF)-κB signaling in triptolide (TPL)-induced sensitivity of pancreatic cancer cells to gemcitabine (GEM).

Methods: , pancreatic cancer PANC-1 cells were treated with lipopolysaccharide (LPS) to activate TLR4, TLR4-siRNA, GEM alone, or GEM plus TPL. , nude mice bearing PANC-1 cell xenografts were treated with GEM, TPL, or both.

We aimed to explore the use of the flash glucose monitoring (FGM) system in hospitalized newly diagnosed type 2 diabetes mellitus (T2DM) patients and to evaluate a new combination therapy of continuous subcutaneous insulin infusion (CSII) with or without liraglutide. This was an open-label, randomized study that was conducted in 60 newly diagnosed T2DM patients. The patients were randomized to receive either CSII (n = 30) or CSII + liraglutide (n = 30).

Diabetic nephropathy (DN) is one of the most frequent complications associated with type I and II diabetes mellitus. Kidneys from patients with DN are characterized by mesangial matrix expansion and increased thickness of the glomerular basement membrane, which are induced by reactive oxygen species (ROS) production. Previous studies have been conducted to investigate this; however, the detailed mechanism of DN progression remains to be elucidated.

Triptolide (TPL) inhibits the growth and proliferation of a wide range of human cancer cells, but the underlying mechanism is largely unknown. Here, we report that TPL induces apoptosis and inhibits proliferation of PANC-1 pancreatic cancer cells by downregulating cyclooxygenase-2 (COX-2) and vascular endothelial growth factor (VEGF). Cell viability and apoptosis were measured by MTT assay and flow cytometry.

Objective: To investigate the role of the Wnt/LRP5/β-catenin signaling pathway in the pathogenesis of postmenopausal osteoporosis.

Methods: Fifty female Wistar rats aged 6-month-old, were randomly divided into control group (NS, n = 24) and ovariectomized group (NOVX, n = 26), NOVX underwent bilateral ovariectomy. At 0, 4 and 8 weeks, all of rats were measured blood estrogen (E(2)) and bone mineral density (BMD), 4 and 8 weeks, low density lipoprotein receptor-related protein 5 (LRP5), β-catenin and Runx2 mRNA in bone were measured respectively by reverse transcription (RT)-PCR.

Background: Iodine 125 (125I) seed irradiation is an effective treatment for unresectable pancreatic cancers. However, the radiobiological mechanisms underlying brachytherapy remain unclear. Therefore, we investigated the influence of continuous and low-energy 125I irradiation on apoptosis, expression of DNA methyltransferases (DNMTs) and cell growth in pancreatic cancers.
