Kangfuxin solution alleviates esophageal stenosis after endoscopic submucosal dissection: A natural ingredient strategy.

Background: Esophageal stricture ranks among the most significant complications following endoscopic submucosal dissection (ESD). Excessive fibrotic repair is a typical pathological feature leading to stenosis after ESD.

Aim: To examine the effectiveness and underlying mechanism of Kangfuxin solution (KFX) in mitigating excessive fibrotic repair of the esophagus post-ESD.

The efficacy and active compounds of Chaihuang Qingyi Huoxue granule to Ameliorate intestinal mucosal barrier injury in rats with severe acute pancreatitis by suppressing the HMGB1/TLR4/NF-κB signaling pathway.

Intestinal mucosal barrier injury represents a critical complication of severe acute pancreatitis (SAP) without effective treatment. This study investigated the efficacy, underlying mechanism, and responsible active compounds of the traditional Chinese medicinal prescription Chaihuang Qingyi Huoxue granule (CHQY) in treating SAP-induced intestinal mucosal barrier injury. SAP was established in Sprague-Dawley rats via intra-pancreaticobiliary duct infusion of sodium taurocholate, followed by oral CHQY administration (3.

Mechanism of Chaihuang-Yishen formula to attenuate renal fibrosis in the treatment of chronic kidney disease: Insights from network pharmacology and experimental validation.

Renal fibrosis represents a pivotal characteristic of chronic kidney disease (CKD), for which effective interventions are currently lacking. The Src kinase activates the phosphatidylinositol-3 kinases (PI3K)/Akt1 pathway to promote renal fibrosis, casting a promising target for anti-fibrosis treatment. Chaihuang-Yishen formula (CHYS), a traditional Chinese medicinal prescription, has a validated efficacy in the treatment of CKD, however, with the underlying mechanism unresolved.

Calycosin inhibited MIF-mediated inflammatory chemotaxis of macrophages to ameliorate ischemia reperfusion-induced acute kidney injury.

Background: Inflammatory macrophage infiltration plays a critical role in acute kidney disease induced by ischemia-reperfusion (IRI-AKI). Calycosin is a natural flavone with multiple bioactivities. This study aimed to investigate the therapeutic role of calycosin in IRI-AKI and its underlying mechanism.

Btg2 Promotes Focal Segmental Glomerulosclerosis via Smad3-Dependent Podocyte-Mesenchymal Transition.

Podocyte injury plays a critical role in the progression of focal segmental glomerulosclerosis (FSGS). Here, it is reported that B-cell translocation gene 2 (Btg2) promotes Adriamycin (ADR)-induced FSGS via Smad3-dependent podocyte-mesenchymal transition. It is found that in FSGS patients and animal models, Btg2 is markedly upregulated by podocytes and correlated with progressive renal injury.

Andrographolide ameliorates hepatic steatosis by suppressing FATP2-mediated fatty acid uptake in mice with nonalcoholic fatty liver disease.

Excessive intrahepatocellular lipid accumulation or steatosis is caused by abnormal lipid metabolism and a common character of nonalcoholic fatty liver disease (NAFLD), which may progress into cirrhosis and hepatocellular cancer. Andrographolide (Andro) is the primary active ingredient extracted from Andrographis paniculata, showing a protective role against dietary steatosis with the mechanism not fully understood. In this study, we showed that administration of Andro (50, 100, and 200 mg/kg/day for 8 weeks, respectively) attenuated obesity and metabolic syndrome in high-fat diet (HFD)-fed mice with improved glucose tolerance, insulin sensitivity, and reduced hyperinsulinemia, hyperglycemia, and hyperlipidemia.

The Smad3-dependent microRNA let-7i-5p promoted renal fibrosis in mice with unilateral ureteral obstruction.

Renal fibrosis is a common feature of all types of chronic kidney disease (CKD) and is tightly regulated by the TGF-β/Smad3 pathway. Let-7i-5p belongs to the let-7 microRNA family with diverse biological functions. It has been reported that let-7i-5p suppresses fibrotic disease in the heart, lungs, and blood vessels, while the role of let-7i-5p in renal fibrosis remains limited.

Role of TGF-Beta Signaling in Beta Cell Proliferation and Function in Diabetes.

Beta (β) cell dysfunction or loss is the common pathological feature in all types of diabetes mellitus (diabetes). Resolving the underlying mechanism may facilitate the treatment of diabetes by preserving the β cell population and function. It is known that TGF-β signaling plays diverse roles in β cell development, function, proliferation, apoptosis, and dedifferentiation.

TGF-Beta as a Master Regulator of Diabetic Nephropathy.

Diabetic nephropathy (DN) is one of the most common complications in diabetes mellitus and the leading cause of end-stage renal disease. TGF-β is a pleiotropic cytokine and has been recognized as a key mediator of DN. However, anti-TGF-β treatment for DN remains controversial due to the diverse role of TGF-β1 in DN.

The Herbal Formula Granule Prescription Mahuang Decoction Ameliorated Chronic Kidney Disease Which Was Associated with Restoration of Dysbiosis of Intestinal Microbiota in Rats.

Chronic kidney disease (CKD) has become a global health issue, and there is increasing evidence showing the beneficial roles of traditional Chinese medicine (TCM) in CKD treatment. Here, we studied the renoprotective role of Mahuang decoction, a famous TCM prescription, in a rat CKD model induced with the combination of doxorubicin and adenine. Our data showed that intragastric administration of Mahuang decoction inhibited the loss of bodyweight and attenuated proteinuria, serum creatinine, and blood urea nitrogen in CKD rats.

Curcumin relieved cisplatin-induced kidney inflammation through inhibiting Mincle-maintained M1 macrophage phenotype.

Background: Acute kidney injury (AKI) is a common kidney disease with a high risk of death and can develop into chronic kidney disease (CKD) and renal failure eventually. Curcumin, an herbal supplement, has been reported exhibiting a renoprotective role in AKI. However, the underlying mechanism is largely unclear.

Helicobacter pylori participates in the pathogenesis of IgA nephropathy.

Increasing evidences have shown that Helicobacter pylori (Hp) is a pathogen closely related to extra-gastric disorders. Our previous in vitro studies had demonstrated that Hp infection, at least via cytotoxin-associated gene A protein (CagA), might play an important role in the pathogenesis of IgA nephropathy (IgAN) by stimulating proliferation and ectopic synthesis of aberrantly glycosylated IgA1 of B cells. However, the relevant clinical evidence of IgAN resulted from Hp infection remain to be elucidated.

CagA promotes proliferation and secretion of extracellular matrix by inhibiting signaling pathway of apoptosis in rat glomerular mesangial cells.

Cytotoxin-associated antigen A (CagA), a major virulence factor of Helicobacter pylori (Hp), is associated with the pathogenesis of peptic ulcer and gastric cancer. Recent researches demonstrated that Hp exists in palatine tonsil in all studied IgA nephropathy (IgAN) patients, most of which were CagA-positive, suggesting that CagA may be a causative pathogenic factor of IgAN. However, the underlying molecular mechanisms and signaling pathway are still largely unclear.

Ginsenoside Rg1 reduces aldosterone-induced autophagy via the AMPK/mTOR pathway in NRK-52E cells.

Aldosterone is a steroid hormone secreted from the adrenal cortex, which regulates blood pressure. Higher concentrations of aldosterone can cause several diseases, including hypertension, diabetic nephropathy and chronic kidney disease. Previous reports have demonstrated that aldosterone has a pathogenic role in renal injury via reactive oxygen species (ROS), which involves the regulation of autophagy.

Comparative proteomic analysis suggests that mitochondria are involved in autosomal recessive polycystic kidney disease.

Autosomal recessive polycystic kidney disease (ARPKD), characterized by ectatic collecting duct, is an infantile form of PKD occurring in 1 in 20 000 births. Despite having been studied for many years, little is known about the underlying mechanisms. In the current study, we employed, for the first time, a MS-based comparative proteomics approach to investigate the differently expressed proteins between kidney tissue samples of four ARPKD and five control individuals.
