Objective: To study the effects of artemisinin on proliferation, apoptosis and Caspase-3 active of rat mesangial cell.
Methods: Rat mesangial cells were incubated with different concentrations of artemisinin, the proliferation, apoptosis and Caspase-3 active of rat mesangial cell were measured by MTT assay, fluorescent inverted microscope and enzyme-labeled analytical instruments respectively.
Results: Compared with control group, the proliferation and Caspase-3 expression of mesangial cell of three other groups were significantly different (P < 0.01). Compared with dexamethasone group, there were significant difference effects of proliferation and Caspase-3 expression of mesangial cell in other two groups of identical concentration drugs (P < 0. 01), especially in the artemisinin + glucocorticoid (ArtGC) group, and the effects of three different drugs on the mesangial cell Caspase-3 expression, proliferation and apoptosis had the tendency of depend on dosage, and mass mortality of mesangial cell in the mediate-dosage and high-dosage ArtGC group.
Conclusion: Artemisinin could inhibit the proliferation of mesangial cell, enhance the expression of Caspase-3 and promote the apoptosis in a dose-dependent manner.

Previous studies have shown that celecoxib or NSAID may paradoxically induce cyclooxygenase-2 (COX-2) expression and trigger inflammation-like responses in airway smooth muscle cells and renal mesangial cells. Despite the extensive research on celecoxib, its atypical biological effect on the induction of COX-2 in astroglial cells within the central nervous system (CNS) remains unexplored. In the present study, we investigated the impact of celecoxib on COX-2 and Glial Fibrillary Acidic Protein (GFAP) expression and explored the mechanisms underlying celecoxib-regulated COX-2 expression in cortical astrocytes of rats.

Introduction: To evaluate the impact of TACI fusion protein (TACI-Ig) on IgA nephropathy (IgAN) in rats, and to explore its mechanism and relationship with TLR4/MyD88/NF-κB pathway.
Method: Sprague Dawley(SD)rats were divided into six groups: control, model, TACI-Ig low dose (TACI-Ig-L), medium dose (TACI-Ig-M), high dose (TACI-Ig-H), and prednisone acetate (PAT) group. The control group and model group received physiological saline injections, while the TACI-Ig groups were administered doses of 7.

Objectives: To investigate the impact of the different proportions of crescent formation on clinical manifestations and pathological features in children with immunoglobulin A vasculitis with nephritis (IgAVN).
Methods: The children with IgAVN were divided into no-crescent group (75 children), ≤25% crescent group (156 children), and >25% crescent group (33 children).
Results: Compared with the no-crescent group, the other two groups had significant increases in 24-hour urinary protein, urinary immunoglobulin G (IgG)/creatinine ratio, urine red blood cell count, fibrinogen, and neutrophil-lymphocyte ratio, a significant reduction in serum IgG, and a significantly higher proportion of children with low albumin and hypercoagulability, pathological grade III+IV or diffuse mesangial proliferation (<0.

Diabetic nephropathy is a prevalent complication of diabetes and stands as the primary contributor to end-stage renal disease. The global prevalence of diabetic nephropathy is on the rise, however, due to its intricate pathogenesis, there is currently an absence of efficacious treatments to enhance renal prognosis in affected patients. The mammalian target of rapamycin (mTOR), a serine/threonine protease, assumes a pivotal role in cellular division, survival, apoptosis delay, and angiogenesis.

The kidney plays an important role in iron homeostasis and mesangial cells (MCs) are phagocytic cells important for glomerular homeostasis. Sickle hemoglobin (HbS) modulators are promising clinical candidates for treatment of sickle cell disease. Although they prevent disease pathophysiology of HbS polymerization and red blood cell (RBC) sickling by increasing hemoglobin oxygen affinity, higher oxygen affinity can also cause transient tissue hypoxia with compensatory increases in erythropoiesis and subsequent increases in RBC turnover.
