OBJECTIVE Oxidative stress is a major contributing factor in the development of diabetic nephropathy. Peroxisome proliferator–activated receptor γ heterozygous mice and Pro12Ala polymorphism PPARG exhibited increased resistance to oxidative stress. Smoking increases production reactive oxygen species, which accelerates under hyperglycemia. To determine whether polymorphism, alone or combination with smoking, contributes nephropathy, case-control study was performed 760 Chinese patients type...

Intracellular glucocorticoid (GC) receptor (GR) function determines tissue sensitivity to GCs and strongly affects the development of type 2 diabetes obesity. 11β-hydroxysteroid dehydrogenase 1 (11β-HSD1) mediates intracellular steroid exposure mouse liver GR by prereceptor reactivation is crucially dependent on hexose-6-phosphate (H6PDH)-generating NADPH system. Pharmacological inhibition 11β-HSD1 improves insulin intolerance Here, we evaluated potential beneficial effects inhibitor...

Long-term glucocorticoid exposure increases the risk for developing type 2 diabetes. Prereceptor activation of availability in target tissue by 11β-hydroxysteroid dehydrogenase 1 (11β-HSD1) coupled with hexose-6-phosphate (H6PDH) is an important mediator metabolic syndrome. We explored whether tissue-specific modulation 11β-HSD1 and H6PDH adipose mediates glucocorticoid-induced insulin resistance lipolysis analyzed effects inhibition on key lipid metabolism genes insulin-signaling cascade....

Uncoupling protein-2 (UCP2) may regulate glucose-stimulated insulin secretion. The current study investigated the effects of berberine, an alkaloid found in many medicinal plants, on oxidative stress and secretion through restoration UCP2 expression high glucose (HG)-treated INS-1E cells rat islets or db/db mouse islets.Mouse pancreatic were isolated. Nitrotyrosine, superoxide dismutase (SOD)-1 AMPK phosphorylation examined by Western blotting. Insulin was measured ELISA. Mitochondrial...

Background and objectives: Renalase, a monoamine oxidase derived from the kidney, can degrade catecholamine (CA) regulate blood pressure as well cardiac function. To investigate changes of serum renalase levels in patients with Type 2 diabetes mellitus (DM) examine correlation other features T2DM. Methods: Seventy-five T2DM 13 healthy volunteers were studied. The CA measured by enzyme linked immunosorbent assay. Several biochemical clinical parameters measured. Results: Serum renalase/CA...

To observe the effect of heat-reinforcing needling on expression profile long non-coding RNA (LncRNA) in synovial tissue rabbits with cold-syndrome type rheumatoid arthritis (RA), so as to explore its mechanisms underlying improvement RA. A total 18 New Zealand were randomly divided into normal, model and (acupuncture) groups, 6 each group. The RA was established by injection mixed solution (emulsifier) ovalbumin powder(80 mg) + NaCl (20 mL) +Freund's complete adjuvant mL), combined cold...

Both blood urea nitrogen (BUN) and creatinine (Cr) are indicators of kidney function, the BUN/Cr ratio has been identified as an independent prognostic marker for adverse outcomes in critically ill patients with various conditions. However, relationship between long-term mortality acute pancreatitis (AP) remains unclear. Hence, primary objective this study was to determine value AP. We conducted a retrospective cohort using data from Medical Information Mart Intensive Care IV (MIMIC-IV)...

Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive malignancy characterized by dense and heterogeneous tumor microenvironment (TME) composed of various cancer-associated fibroblasts (CAFs). In this study, we explored the composition proportions CAF subtypes within PDAC TME identified three distinct CAF-related subtypes: iCAF-rich, myCAF-rich, PSC-rich. We observed significant heterogeneity in populations across different patients, which correlated with patient prognosis...
