Ureic clearance granule, alleviates renal dysfunction and tubulointerstitial fibrosis by promoting extracellular matrix degradation in renal failure rats, compared with enalapril.

Ethnopharmacological Relevance: Chinese herbal compound prescription has a unique therapeutic action on chronic kidney disease (CKD) in China. In clinics, Uremic Clearance Granules (UCG), a compounded Chinese patent medicine, has been frequently used to treat chronic renal failure (CRF) patients for nearly 30 years, however, the deep therapeutic mechanisms involved in vivo remain a challenge. This study aims to demonstrate the effects and mechanisms of UCG on renal dysfunction and tubulointerstitial fibrosis by regulating extracellular matrix (ECM) degradation and transforming growth factor (TGF)-beta1/Smad signaling activity in vivo, compared with enalapril.

[Overview research of uremic ulearance granule treating chronic renal failure].

The effective bioactivity compositions of uremic clearance granul (UCG) include isoflavonoids, emodin, astragaloside, paeoniflorin, salvianolic acid A, and so on. The effects of UCG treating chronic renal failure (CRF) in clinical pharmacodynamics mainly refer to improve renal function and the complications of CRF. The mechanisms involved in vivo basically include depressing transforming growth factor (TGF)-beta1 over-expression, lessening podocyte injury,inhibiting tubular epithelial myofibroblast transdifferentiation, ameliorating microinflammation status, retarding oxidative stress, and alleviating insulin resistance.

[Molecular mechanisms of renal extracellular matrix degradation and interventional effects of Chinese herbal medicine].

The reduction of extracellular matrix (ECM) degradation in kidney is taken as the morphological features and pathological base in renal injury in chronic kidney disease (CKD). ECM degradation is controlled by the catabolic enzyme systems in glomerulus and renal interstitium, in which matrix metalloproteinases (MMPs) play a key role. The expression and activity of MMPs are regulated by the classical pathway, such as the genic transcription, the activation of zymogen, and the specific inhibitor.

[Effects of huangkui capsule on renal inflammatory injury by intervening p38MAPK signaling pathway in rats with adriamycin-induced nephropathy].

Objective: To explore the potential mechanisms of huangkui capsule (HKC), an extract from Abelmoschus manihot (AM), for ameliorating renal inflammatory injury by regulating p38 mitogen-activated protein kinase (MAPK) signaling pathway in rats with adriamycin-induced nephropathy (ADRN).

Method: Nineteen Sprague-Dawley (SD) rats were randomly divided into three groups, the sham-operation group, the untreated model group,and the HKC-treated group. Rats in the untreated model group and the HKC-treated group were made into ADRN model by right nephrectomy and twice intravenous injections of adriamycin( ADR, 0.

Contrasting dose-effects of multi-glycoside of Tripterygium wilfordii HOOK. f. on glomerular inflammation and hepatic damage in two types of anti-Thy1.1 glomerulonephritis.

Multi-glycoside, one of the extracted compounds from Tripterygium wilfordii HOOK. f. (GTW), has been shown to be clinically effective in suppressing glomerular inflammation in chronic kidney disease.
