Metadherin silencing results in the inhibition of pyroptosis in lipopolysaccharide/adenosine triphosphate - stimulated renal tubular epithelial cells.

Pyroptosis is induced following inflammation via activation of the NLRP3 inflammasome. Lipopolysaccharide (LPS)-induced acute inflammation causes pyroptosis in renal tubular epithelial cells, which aggravates kidney damage and is involved in physiopathological processes in multiple renal diseases. Metadherin (Mtdh) induces inflammation by NLRP3 inflammasome activation.

Background: In recent years, sodium-glucose co-transporter 2 inhibitors (SGLT2is) have been increasingly used in the treatment of patients with non-alcoholic fatty liver disease (NAFLD). This updated meta-analysis aimed to evaluate the efficacy and safety of SGLT2is for patients with NAFLD.

Methods: PubMed, Embase, Cochrane Library, Web of Science, Wan Fang, China National Knowledge Infrastructure and VIP databases were searched for relevant studies from inception to April 30, 2021.

Coagulation parameters may predict clinical outcomes in patients with septic acute kidney injury.

Background: Acute kidney injury (AKI) and coagulation disorders are common complications of sepsis that affect its prognosis. However, the relationship between coagulation function and the prognosis of septic AKI has not been fully elucidated.

Materials And Methods: In this retrospective study, clinical data from patients with septic AKI admitted to the First Affiliated Hospital of Guangxi Medical University from June 2016 to March 2019 were analyzed.

The impact of poaching and regime switching on the dynamics of single-species model.

It is widely recognized that the criminal act of poaching has brought tremendous damage to biodiversity. This paper employs a stochastic single-species model with regime switching to investigate the impact of poaching. We first carry out the survival analysis and obtain sufficient conditions for the extinction and persistence in mean of the single-species population.

CMIP SNPs and their haplotypes are associated with dyslipidaemia and clinicopathologic features of IgA nephropathy.

The relationship between serum lipid profiles and related clinicopathologic features of IgA nephropathy (IgAN) and c-Maf-inducing protein (CMIP) gene polymorphisms is unclear. The present study was designed to examine the effect of CMIP single-nucleotide polymorphisms (SNPs) on dyslipidaemia and clinicopathologic features of IgAN. Clinical and pathological data from patients with IgAN diagnosed at the First Affiliated Hospital of Guangxi Medical University were collected.

Key genes of renal tubular necrosis: a bioinformatics analysis.

Background: To explore the key genes in renal tubular necrosis.

Methods: Microarray datasets GSE69644, GSE27168, and GSE2027 were downloaded from the Gene Expression Omnibus database. Differentially expressed genes (DEGs) were identified and we performed functional enrichment analysis.

Estimating total small solute clearance in patients treated with continuous ambulatory peritoneal dialysis without urine and dialysate collection.

Background: International Society for Peritoneal Dialysis guidelines recommend to routinely monitor the total measured clearance (mCl) of small solutes such as creatinine; however, collection of 24-h urine and peritoneal dialysis (PD) fluid is burdensome to patients and prone to errors. We hypothesized that equations could be developed to estimate mCl (estimated clearance (eCl)) using endogenous filtration markers.

Methods: In the Guangzhou PD Study ( = 980), we developed eCl equations using linear regression in two-third and validated them in the remaining one-third.

Roxadustat for Anemia in Patients with Kidney Disease Not Receiving Dialysis.

Background: Roxadustat (FG-4592) is an oral inhibitor of hypoxia-inducible factor (HIF) prolyl hydroxylase that stimulates erythropoiesis and regulates iron metabolism. In phase 2 studies involving patients with chronic kidney disease, roxadustat increased levels of endogenous erythropoietin to within or near the physiologic range, along with increasing hemoglobin levels and improving iron homeostasis. Additional data are needed regarding the efficacy and safety of roxadustat for the treatment of anemia in patients with chronic kidney disease who are not undergoing dialysis.

Association between gene polymorphism and renal function in patients with IgA nephropathy.

Background: Studies have shown that the occurrence and development of IgA nephropathy (IgAN) are genetically susceptible, but the relationship between vitamin D receptor () gene polymorphisms and renal function in IgAN patients is unclear.

Methods: We investigated the relationship between (rs2228570) single nucleotide polymorphism (SNP) and renal function and related clinicopathologic parameters in IgAN patients. Clinical and pathological data of 282 IgAN patients treated at the First Affiliated Hospital of Guangxi Medical University were collected, and genotypes were determined by PCR and direct sequencing.

Development and Validation of Residual Kidney Function Estimating Equations in Dialysis Patients.

Rationale & Objective: Measurement of residual kidney function is recommended for the adjustment of the dialysis prescription, but timed urine collections are difficult and prone to errors. Equations to calculate residual kidney function from serum concentrations of endogenous filtration markers and demographic parameters would simplify monitoring of residual kidney function. However, few equations to estimate residual kidney function using serum concentrations of small solutes and low-molecular-weight proteins have been developed and externally validated.

Matrine suppresses lipopolysaccharide-induced fibrosis in human peritoneal mesothelial cells by inhibiting the epithelial-mesenchymal transition.

Background: Peritoneal fibrosis is the primary reason that patients with end-stage renal disease (ESRD) have to cease peritoneal dialysis. Peritonitis caused by Gram-negative bacteria such as Escherichia coli (E. coli) were on the rise.

The association of the rs16955379 polymorphism with dyslipidemia and the clinicopathological features of IgA nephropathy.

Immunoglobulin A nephropathy (IgAN) is among the most common primary glomerular diseases. The prognosis in IgAN is affected by dyslipidemia, a risk factor for cardiovascular disease. The c-Maf inducing protein (CMIP) gene has been found to be associated with lipid metabolism.

Association Analysis of the MHC in Lupus Nephritis.

Lupus nephritis (LN) is one of the most prevalent and serious complications of SLE, with significant effects on patient and renal survival. Although a large number of genetic variants associated with SLE have been identified, biomarkers that correlate with LN are extremely limited. In this study, we performed a comprehensive sequencing analysis of the whole MHC region in 1331 patients with LN and 1296 healthy controls and validated the independent associations in another 950 patients with LN and 1000 controls.
