Association of elevated circulating monocyte-platelet aggregates with hypercoagulability in patients with nephrotic syndrome.

Background: Hypercoagulability emerges as a central pathological feature and clinical complication in nephrotic syndrome. Increased platelet activation and aggregability are closely related to hypercoagulability in nephrotic syndrome. Monocyte-platelet aggregates (MPAs) have been proposed to represent a robust biomarker of platelet activation.

Quercetin improves diabetic kidney disease by inhibiting ferroptosis and regulating the Nrf2 in streptozotocin-induced diabetic rats.

Diabetic kidney disease (DKD) is a leading factor in end-stage renal disease. The complexity of its pathogenesis, combined with the limited treatment efficacy, necessitates deeper insights into potential causes. Studies suggest that ferroptosis-driven renal tubular damage contributes to DKD's progression, making its counteraction a potential therapeutic strategy.

Epidemiology and risk factors for progression in Chinese patients with IgA nephropathy.

Background: IgA nephropathy (IgAN) is one of the main causes of primary glomerulonephritis worldwide, and it is also the main primary disease leading to chronic kidney disease. The purpose of this study is to evaluate the epidemiology and risk factors for progression in Chinese patients with IgAN.

Methods: In this retrospective study, 246 patients with renal biopsy-proven IgAN were enrolled from January 2012 to June 2018.

Plasma sMer, sAxl and GAS6 levels correlate with disease activity and severity in lupus nephritis.

Objective: The purpose of this study is to determine whether TAM receptors and ligands associated with the activity and severity of lupus nephritis.

Methods: Clinical data were statistically analysed and studied in 122 SLE patients, diagnosed from 2013 to 2016 in First Hospital Affiliated to Harbin Medical University. Levels of TAM receptors and ligands in the plasma of 122 SLE patients were measured by ELISA.

Original Research: Atorvastatin prevents rat cardiomyocyte hypertrophy induced by parathyroid hormone 1-34 associated with the Ras-ERK signaling.

We investigated the effects of atorvastatin (Ator) on cardiomyocyte hypertrophy (CMH) induced by rat parathyroid hormone 1-34 (PTH1-34) and Ras-extracellular signal regulated protein kinases 1/2 (ERK1/2) signaling. Rat cardiomyocytes were randomly divided into seven groups: normal controls (NC), PTH1-34 (10(-7) mol/L), Ator (10(-5) mol/L), farnesyl transferase inhibitors-276 (FTI-276, 4 × 10(-5) mol/L), PTH1-34 + Ator, PTH1-34 + FTI-276 and PTH1-34 + Ator + mevalonic acid (MVA, 10(-4) mol/L). After treatment, the hypertrophic responses of cardiomyocytes were assessed by measuring cell diameter, detecting protein synthesis, and single-cell protein content.

Effect of the oral iron chelator deferiprone in diabetic nephropathy rats.

Background: The aim of the present study was to investigate the effects of the iron chelator deferiprone in diabetic nephropathy (DN) rats and the mechanisms involved.

Methods: Thirty-two male Wistar rats (180-220 g, 6 weeks old) were randomly divided into a control group, a DN group and two DN groups treated with either 50 or 100 mg/kg per day deferiprone. The DN group was established by feeding of a high-carbohydrate-fat diet and injection of 35 mg/kg streptozotocin into the vena caudalis.

Co-Positivity for Anti-dsDNA, -Nucleosome and -Histone Antibodies in Lupus Nephritis Is Indicative of High Serum Levels and Severe Nephropathy.

Objective: To characterize the significance of correlated autoantibodies in systemic lupus erythematosus (SLE) and its complication lupus nephritis (LN) in a large cohort of patients.

Methods: Clinical data were statistically analyzed in 1699 SLE patients with or without nephritis who were diagnosed and treated during 2002-2013 in the northeast region of China. Reactivity to a list of 16 autoantibodies was detected by the serum test Euroline ANA profile (IgG).

Relationship between hypoalbuminemia, hyperlipidemia and renal severity in patients with lupus nephritis: a prospective study.

Aim Of The Study: The purpose is to evaluate the relationship between hypoalbuminemia, hyperlipidemia, nephrotic and renal severity in patients with lupus nephritis.

Material And Methods: Autoantibodies and serological parameters were measured and analyzed in 429 patients with lupus nephritis in a single centre.

Results: The prevalence for anti-dsDNA, anti-nucleosome and anti-histone was higher in the nephrotic syndrome (NS) patients than that in non-NS patients (p < 0.

Iron chelator alleviates tubulointerstitial fibrosis in diabetic nephropathy rats by inhibiting the expression of tenascinC and other correlation factors.

Tubulointerstitial fibrosis is the final common pathway to diabetic nephropathy. However, only a few drugs are responsible for this pathologic process. We investigated the possible effect of deferiprone (iron chelator) treatment on experimental diabetic nephropathy (DN) rats, as well as the mechanisms involved in this process.

[Atorvastatin attenuates parathyroid hormone 1-34 induced cardiomyocytes hypertrophy through downregulating K-Ras-ERK1/2 pathway].

Objective: To investigate the effects of atorvastatin on parathyroid hormone 1-34 (PTH1-34) induced neonatal rat cardiomyocytes hypertrophy and on the expression changes of small GTP-binding protein (K-Ras) and extracellular signal regulated protein kinases 1/2 (ERK1/2).

Methods: Neonatal rat cardiomyocytes hypertrophy was established with 10(-7) mol/L rPTH1-34 in the presence or absence of 10(-5) mol/L atorvastatin or 10(-4) mol/L mevalonic acid (MVA). Cardiomyocyte diameter was measured by Motic Images Advanced 3.

Simultaneous positivity for anti-DNA, anti-nucleosome and anti-histone antibodies is a marker for more severe lupus nephritis.

Objective: The purpose of this study is to examine autoantibody profile of systemic lupus erythematosus (SLE) patients with lupus nephritis (LN) and to establish the correlation between the antibody reactivity and disease activity of LN.

Methods: Autoantibodies and serological parameters were measured and analyzed in 589 SLE patients. The associations of the co-positivity of anti-dsDNA, -nucleosome and -histone antibodies (3-pos) with clinical, serological and outcome parameters were analyzed.

The sphingosine-1-phosphate receptor agonist FTY720 prevents the development of anti-glomerular basement membrane glomerulonephritis.

The sphingosine-1-phosphate (S1P) agonist FTY720 prolongs the survival of organ allograft and attenuates autoimmune-mediated injury in experimental models. Most cases of glomerulonephritis (GN) in human appear to be immunologically initiated. In this study, we evaluated the potential therapeutic role of FTY720 in GN via a mouse anti-glomerular basement membrane (GBM) model.
