[Exploring molecular mechanisms of fucoidan in improving human proximal renal tubular epithelial cells aging by targeting autophagy signaling pathways].

Fucoidan(FPS) is an effective component of the Chinese patent medicine named Haikun Shenxi, which treats schronic renal failure in clinics, and has the potential anti-aging effects. However, it is still unclear whether FPS can improve renal aging, especially the molecular mechanism of its anti-aging. The human proximal renal tubular epithelial cells(HK-2) in vitro were divided into normal group(N), D-gal model group(D), low dose of FPS group(L-FPS), high dose of FPS group(H-FPS) and vitamin E group(VE), and treated by the different measures, respectively.

[Multi-targeted therapeutic effects of Huangkui Capsules on insulin resistance and urine microalbumin in early diabetic kidney disease patients].

To observe the multi-targeted therapeutic effects of Huangkui Capsules(HKC)on insulin resistance(IR)and urine microalbumin in the early diabetic kidney disease(DKD)patients. The case data from the 83 DKD patients at G2 and A2 stage were collected respectively and analyzed retrospectively. According to the different treatment,all patients were divided into the control(A)group(40 cases)and the treated(B)group(43 cases).

[Molecular regulatory mechanisms of hypoxia-inducible factor and interventional effect of Chinese herbal medicine].

Hypoxia-inducible factors(HIFs)are the key transcription factors that sense and regulate cellular oxygen concentration in vivo. HIF-1 is composed of 2 subunits,α and β,in which,the molecular regulatory mechanism of HIF-1α involves the main processes of its degradation and activation. The degradation of HIF-1α is regulated by oxygen-dependent pathways,including "von hippel-lindau protein(pVHL)-dependent pathway" and "pVHL-independent pathway".

Total Flavones of Remodels Gut Microbiota and Inhibits Microinflammation in Chronic Renal Failure Progression by Targeting Autophagy-Mediated Macrophage Polarization.

Background: Recently, progression of chronic renal failure (CRF) has been closely associated with gut microbiota dysbiosis and intestinal metabolite-derived microinflammation. In China, total flavones of (TFA), a component of , has been widely used to delay CRF progression in clinics for the past two decades. However, the overall therapeutic mechanisms remain obscure.

[Molecular regulative mechanisms of NLRP3 inflammasome activation in diabetic nephropathy and interventional effects of Chinese herbal medicine].

The progression of renal damage in diabetic nephropathy(DN)is closely related to Nod-like receptor protein3(NLRP3)inflammasome activation. The characteristics of NLRP3 inflammasome activation include the changed expression and combination levels of NLRP3, apoptosis-associated speck-like protein(ASC)and pro-caspase-1, the increased expression levels of caspase-1, interleukin(IL)-1β and IL-18 and the excessive release levels of the relative inflammatory mediators. Its molecular regulative mechanisms involve the activation of multiple signaling pathways including reactive oxygen species(ROS)/thioredoxin-interacting protein(TXNIP)pathway, nuclear factor(NF)-κB pathway, nuclear factor erythroid-related factor 2(Nrf2)pathway, long non-coding RNA(lncRNA)pathway and mitogen-activated protein kinases(MAPKs)pathway.

[Triptolide inhibits NLRP3 inflammasome activation and ameliorates podocyte epithelial-mesenchymal transition induced by high glucose].

The aim of this paper was to explore the effects of triptolide( TP),the effective component of Tripterygium wilfordii on improving podocyte epithelial-mesenchymal transition( EMT) induced by high glucose( HG),based on the regulative mechanisms of Nod-like receptor protein 3( NLRP 3) inflammasome in the kidney of diabetic kidney disease( DKD). The immortalized podocytes of mice in vitro were divided into the normal( N) group,the HG( HG) group,the low dose of TP( L-TP) group,the high dose of TP( HTP) group and the mannitol( MNT) group,and treated by the different measures,respectively. More specifically,the podocytes in each group were separately treated by D-glucose( DG,5 mmol·L~(-1)) or HG( 30 mmol·L~(-1)) or HG( 30 mmol·L~(-1)) + TP( 5 μg·L~(-1))or HG( 30 mmol·L~(-1)) + TP( 10 μg·L~(-1)) or DG( 5 mmol·L~(-1)) + MNT( 24.

[Molecular mechanisms of non-coding RNA regulating autophagy and interventional effects of Chinese herbal medicine].

Long non-coding RNAs(lncRNAs) and microRNAs(miRNAs),as members of the non-coding RNA family,play important roles in upstream processes that regulate autophagy in mammalian cells. LncRNA and miRNA participate in various phases of the process of autophagy,including initiation,vesicle nucleation,autophagosome maturation and autophagosome fusion. Some non-coding RNAs exert bidirectional regulatory functions in the process of autophagy,include the maternally expressed gene 3(MEG3),H19 and miR-21,whereas others either inhibit autophagy(including GAS5,miR-34 a and miR-30 a) or promote autophagy(including MALAT1,miR-152 and miR-24).

Shenkang injection, a modern preparation of Chinese patent medicine, diminishes tubulointerstitial fibrosis in obstructive nephropathy via targeting pericyte-myofibroblast transition.

Shenkang injection (SKI), a modern preparation of Chinese patent medicine, has been widely applied to clinical therapy in the chronic renal failure patients. However, it remains elusive whether SKI can ameliorate tubulointerstitial fibrosis (TIF) . Recently, pericyte-myofibroblast transition (PMT) plays an important role in the pathogenesis of TIF in obstructive nephropathy (ON).

[Molecular mechanisms of insulin resistance and interventional effects of Chinese herbal medicine].

It is considered that insulin resistance(IR)and its signaling pathway disorder are one of pathogenesis that causes insulin target-organs/issues lesions and their slow progression. The clinical diagnosis index of IR is the homeostatic model of insulin resistance(HOMA-IR)based on fasting blood-glucose and fasting serum insulin. Furthermore, the emerging IR biomarkers including adiponectin may be the references for clinical diagnosis.

Huangkui capsule alleviates renal tubular epithelial-mesenchymal transition in diabetic nephropathy via inhibiting NLRP3 inflammasome activation and TLR4/NF-κB signaling.

Background: Huangkui capsule (HKC), an anti-inflammatory Chinese modern patent medicine, has been now widely applied to the clinical therapy of diabetic nephropathy (DN). However, the overall therapeutic mechanisms in vivo are still unclear. Renal tubular epithelial-to-mesenchymal transition (EMT) is one of the major pathogenesis of renal interstitial fibrosis in DN.
