Ethnopharmacology Fuzheng Huayu recipe (FZHY) was formulated on the basis of Chinese medicine theory in treating liver fibrosis. It has a significant efficacy against liver fibrosis caused by chronic hepatitis B, with the action mechanisms of inhibition of hepatic stellate cell activation, protection of hepatocyte oxidative injury and regulations of hepatic matrix remodeling etc. Aim of the study To identify the absorbed components and metabolites of Danshen in FZHY in rat serum, and find their active components for anti-liver fibrosis. Material and methods A valid high performance liquid chromatography-electrospray ionization ion trap mass spectrometry (HPLC-ESI/MSn) method was established to investigate the absorbed and metabolized compounds of Danshen in FZHY in rat serum after oral administration. Mass spectra were acquired in both negative and positive modes. Otherwise, to evaluate the anti-hepatic fibrosis efficacies of absorbed and metabolized compounds, the LX-2 cell line of hepatic stellate cell (HSC), which was crucial cellular basis of fibrogenesis, was cultured and incubated with absorbed compounds, the cytotoxicity was determined with the cellomics Multiparameter Cytotoxicity Kit 1 by High Content Screening (HCS), the cell proliferation was assayed with EdU-DNA incorporation, and the cell activation was analyzed through α-smooth muscle actin (α-SMA) expression with high content screening technology. Results More than 11 compounds and 2 metabolites from Danshen were identified in the serum after oral administration of FZHY by comparing their mass spectra and retention behavior with reference compounds or literature data. Among these compounds, there were no obvious changes in nuclear morphology, membrane permeability with blow 96 μM of six polar compounds treatment in comparison with control cells, respectively. And the salvianolic acid B (6 μM, 48 μM), caffeic acid (6 μM, 48 μM) and rosmarinic acid (48 μM) could obviously inhibit LX-2 cells proliferation, down-regulate α-SMA expression. Conclusion The results proved that the established method could be applied to analyze the absorbed into blood compounds of Danshen after oral administration FZHY. These absorbed compounds included 11 compounds and 2 metabolites of Danshen. Among them, the salvianolic acid B, caffeic acid and rosmarinic acid were the effective components of FZHY to anti-hepatic fibrosis effects. © 2013 Elsevier Ireland Ltd. All rights reserved.

Aim: To investigate the mechanism of action of Fuzheng Huayu recipe (FZHY) and vitamin E (Vit E) against renal interstitial fibrosis related to transforming growth factor-beta1 (TGF-β1) mediated tubular epithelial-to-mesenchymal transition. Materials and methods: Renal interstitial fibrosis was induced by administration of HgCl2 at a dose of 8mg/kg body weight once a day for 9 weeks. Rats were randomly divided into four groups: normal, model, FZHY, and Vit E group. Rats in the latter two groups were treated with the FZHY recipe and Vit E respectively. HK-2 cells were treated with TGF-β1 for 24h, followed by incubation with either SB-431542 (a potent and specific inhibitor of TβR-I kinase) or FZHY drug-containing serum for another 24h. Hyp content in rat kidney tissue was assayed with Jamall's method and collagen deposition in kidney was visualized using Masson stain. Protein expression of TGF-β1, TβR-I, Smad2, p-Smad2, Smad3, and p-Smad3 was analyzed by Western blotting. Protein expression and the location of Smad3 in kidney was assayed by immunohistochemistry, E-cadherin, cytokeratin 18 (CK-18), α-SMA and TGF-β1 by immunofluorescent stain. Results: FZHY and Vit E inhibited renal collagen deposition and reduced Hyp content significantly. They upregulated E-cadherin protein expression and down-regulated the protein expression of α-SMA, TGF-β1, p-Smad2, p-Smad3, and TβR-I. Lastly, they inhibited the nuclear translocation of Smad3 in fibrotic kidney tissue. FZHY drug-containing serum significantly upregulated the expression of CK-18 and down-regulated the expression of α-SMA, TβR-I, p-Smad2/3 in TGF-β1 stimulated HK-2 cells. Conclusion: The mechanism of action of FZHY and Vit E against renal interstitial fibrosis is related to the reversal of tubular EMT induced by TGF-β1. © 2009 Elsevier Ireland Ltd.

Objectives Postoperative ileus is major cause of postoperative complication and prolonged hospitalization. Jatrorrhizine, which is a protoberberine alkaloid isolated from the medicinal plants Berberis aristata and Coptis chinensis, has been found to increase contractility of gastric antral and ileum smooth muscles of rat gastrointestinal tract. We have investigated whether jatrorrhizine could offset gastrointestinal transit in rat with postoperative ileus. Methods Postoperative ileus was induced by laparotomy with intestinal manipulation under anaesthesia. Gastrointestinal transit was evaluated by measurement of gastric emptying, geometric centre and the migration of Evans blue. Key findings Postoperative ileus significantly delayed gastric emptying and intestinal transit. Jatrorrhizine dose-dependently (0.1, 0.3 and 1 mg/kg) offset delayed gastric emptying and intestinal transit (geometric centre and the migration of Evans blue) in postoperative ileus. Pretreatment of animals with atropine inhibited the action of jatrorrhizine on gastric emptying and intestinal transit, but pretreatment of animals with SB204070 did not influence the effect of jatrorrhizine on gastric emptying and intestinal transit in postoperative ileus. Conclusions Jatrorrhizine offset postoperative ileus-induced delayed gastric emptying and intestinal transit in rats, an action mediated via the cholinergic pathway, but not involving activation of 5-HT 4 receptors. © 2011 Royal Pharmaceutical Society.

Accumulating evidence indicates that disruption of the gut microbiota by a high-fat diet (HFD) may play a pivotal role in the progression of metabolic disorders such as non-alcoholic fatty liver disease (NAFLD). In this study, the structural changes of gut microbiota were analyzed in an HFD-induced NAFLD rat model during treatment with an ancient Chinese herbal formula (CHF) used in clinical practice - Qushi Huayu Fang. CHF treatment significantly reduced body weight, alleviated hepatic steatosis, and decreased the content of triglycerides and free fatty acids in the livers of the rats. Gut microbiota of treated and control rats were profiled with polymerase chain reaction-denaturing gradient gel electrophoresis and bar-coded pyrosequencing of the V3 region of 16S rRNA genes. Both analyses indicated that the CHF-treated group harbored significantly different gut microbiota from that of model rats. Partial least squares discriminant analysis and taxonomy-based analysis were further employed to identify key phylotypes responding to HFD and CHF treatment. Most notably, the genera Escherichia/. Shigella, containing opportunistic pathogens, were significantly enriched in HFD-fed rats compared to controls fed normal chow (P< 0.05) but they decreased to control levels after CHF treatment. Collinsella, a genus with short chain fatty acid producers, was significantly elevated in CHF-treated rats compared to HFD-fed rats (P< 0.05). The results revealed that the bacterial profiles of HFD-induced rats could be modulated by the CHF. Elucidation of these differences in microbiota composition provided a basis for further understanding the pharmacological mechanism of the CHF. © 2013 Elsevier GmbH.

Hepatic fibrosis is a common pathological process of chronic liver diseases and would lead to cirrhosis, and Fuzheng Huayu (FZHY) is an effective Chinese herbal product against liver fibrosis. This study observes FZHY influence on proteome of fibrotic liver with differential proteomic approach and aims to understand FZHY multiple action mechanisms on liver fibrosis. The liver fibrosis models were induced with intraperitoneal injection of dimethylnitrosamine for 4 weeks in rats and divided into model control (model) and FZHY-treated (FZHY) groups, while normal rats were used as normal control (normal). After model establishment, rats in FZHY groups were administered 4 g/kg wt of FZHY for 4 weeks, and normal and model groups were given the same volume of saline. The liver proteins in the above 3 groups were separated by two-dimensional gel electrophoresis (2-DE), the differentially expressed spots were analyzed and compared between normal and model or model and FZHY groups, and then the proteins were identified with mass spectrum analysis and validated partially with western blot and real-time PCR. 10001200 spots were displayed on each 2D gel, and a total of 61 protein spots were found with significant intensity difference between normal control or FZHY and model control. 23 most obviously differential spots were excised, and in-gel digestion and 21 peptide mass fingerprints (PMF) were obtained with MALDI-TOF MS analysis, and 14 proteins were identified through protein database searching. Among 14 differentially expressed proteins, 8 proteins in normal and FZHY groups had the same tendency of differential expression compared with the ones in model group. And one of them, vimentin, was validated by western blot and real-time PCR analyses. Our study reveals 12 proteins responsible for fibrogenesis induced by DMN in rats, and among them, 8 proteins in fibrotic liver were regulated by FZHY, including aldehyde dehydrogenase, vimentin isoform (CRA-b), gamma-actin, vimentin, fructose-bisphosphate aldolase B, aldo-keto reductase, S-adenosylhomocysteine hydrolase isoform, and HSP90. It indicates that the action mechanism of FZHY antiliver fibrosis may be associated with modulation of proteins associated with metabolism and stress response, as well as myofibroblast activation. The study provides new insights and data for exploring the liver fibrogenesis pathophysiology and FZHY action mechanism against liver fibrosis. © 2013 Hongdong Xie et al.

Puerarin, an isoflavone component extracted from Kudzu (Pueraria lobata), has been demonstrated to alleviate alcoholrelated disorders. Our study examined whether puerarin ameliorates chronic alcoholic liver injury through inhibition of endotoxin gut leakage, the subsequent Kupffer cell activation, and endotoxin receptors expression. Rats were provided with the Liber-DeCarli liquid diet for 8 weeks. Puerarin (90 mg/kg or 180 mg/kg daily) was orally administered from the beginning of the third week until the end of the experiment. Chronic alcohol intake caused increased serum alanine aminotransferase, aspartate aminotransferase, hepatic gamma-glutamyl transpeptidase, and triglyceride levels as well as fatty liver and neutrophil infiltration in hepatic lobules as determined by biochemical and histologic assays. A significant increase of liver tumor necrosis factor a was detected by enzyme-linked immunosorbent assay. These pathologic effects correlated with increased endotoxin level in portal vein and upregulated protein expression of hepatic CD68, lipopolysaccharide- binding protein, CD14, Toll-like receptor 2, and Toll-like receptor 4. Meanwhile, the intestinal microvilli were observed to be sparse, shortened, and irregularity in distribution under the transmission electron microscope in conjunction with the downregulated intestinal zonula occludens-1 protein expression. These hepatic pathologic changes were significantly inhibited in puerarintreated animals as were the endotoxin levels and hepatic CD68 and endotoxin receptors. Moreover, the pathologic changes in intestinal microvillus and the decreased intestinal zonula occludens-1 were also ameliorated with puerarin treatment. These results thus demonstrate that puerarin inhibition of endotoxin gut leakage, Kupffer cell activation, and endotoxin receptors expression is involved in the alleviation of chronic alcoholic liver injury in rats. © 2013 by The American Society for Pharmacology and Experimental Therapeutics.

Background: What was the relationship of Fuzheng Huayu recipe (FZHY) inhibiting hepatocyte apoptosis and HSC activation at different stage of liver fibrosis? In order to answer this question, the study was carried out to dynamically observe FZHY's effect on hepatocyte apoptosis and HSC activation and further explored underling mechanism of FZHY against hepatocyte apoptosis. Methods: Mice were randomly divided into four groups: normal, model, FZHY, and N-acetylcystein (NAC) groups. Acute hepatic injury and liver fibrosis in mice were induced by CCl4. Three days before the first CCl4 injection, treatment with FZHY powder or NAC respectively was started. In vitro, primary hepatocytes were pretreated with FZHY medicated serum or Z-VAD-FMK and then incubated with ActD and TNF-α. Primary HSCs were treated with DNA from apoptotic hepatocytes incubated by Act D/TNF-α or FZHY medicated. Liver sections were analyzed for HE staining and immunohistochemical evaluation of apoptosis. Serum ALT and AST, Alb content and TNF-α expression in liver tissue were detected. Hyp content was assayed and collagen deposition was visualized. Expressions of α-SMA and type I collagen were analyzed by immunofluorescence and immunoblotting. Flow cytometry, immunofluorescence, and DNA ladder for hepatocyte apoptosis and immunoblotting for TNF-R1, Bcl-2 and Bax were also analyzed. Results: Mice showed characteristic features of massive hepatocytes apoptosis in early stage of liver injury and developed severe hepatic fibrosis in later phase. FZHY treatment significantly alleviated acute liver injury and hepatocyte apoptosis, and inhibited liver fibrosis by decreasing α-SMA expression and hepatic Hyp content. In vitro, primary hepatocytes were induced by TNF-α and Act D. The anti-apoptotic effect of FZHY was generated by reducing TNFR1 expression and balancing the expressions of Bcl-2 and Bax. Meanwhile, the nuclear DNA from apoptotic hepatocytes stimulated HSC activation in a dose dependent manner, and the DNA from apoptotic hepatocytes treated with FZHY or Z-VAD-FMK reduced HSC activation and type I collagen expression. Conclusion: These findings suggested that FZHY suppressed hepatocyte apoptosis through regulating mediators in death receptor and mitochondrial pathways, and the effect of FZHY on hepatocyte apoptosis might play an important role in inhibiting liver fibrosis. © 2014 Tao et al.

Background: Salvianolic Acid B (Sal B) is a water-soluble component from Danshen (a traditional Chinese herb widely used for chronic renal diseases) with anti-oxidative and cell protective properties. Sal B also has potential protective effects on renal diseases. Tubular epithelial cells can undergo epithelial-to-mesenchymal transition (EMT), which plays an important role in the pathogenesis of renal interstitial fibrosis (RIF) and is mainly regulated by TGF-β1/Smads pathway. The aims of the study are to investigate the effect of Sal B on tubular EMT in vivo and in vitro, and to elucidate its underlying mechanism against EMT related to TGF-β1/Smads pathway.Results: For in vivo experiments, RIF was induced in rats by oral administration of HgCl2and prophylaxised with Sal B and vitamin E. The protein expression of E-cadherin was down-regulated, while the expression of α-SMA, TGF-β1, TβR-I, p-Smad2/3 and the activity of matrix metalloproteinase-2 (MMP-2) were up-regulated in kidneys of model rats when compared with those of normal rats. In contrast, Sal B and vitamin E significantly attenuated the expression of α-SMA, TGF-β1, TβR-I, p-Smad2/3, and MMP-2 activity, but increased E-cadherin expression. For in vitro experiments, HK-2 cells were incubated with TGF-β1 to induce EMT, and the cells were co-cultured with 1 and 10 μM Sal B or SB-431542 (a specific inhibitor of TβR-I kinase). TGF-β1 induced a typical EMT in HK-2 cells, while it was blocked by Sal B and SB-431542, as evidenced by blocking morphologic transformation, restoring E-cadherin and CK-18 expression, inhibiting α-SMA expression and F-actin reorganization, and down-regulating MMP-2/9 activities in TGF-β1 mediated HK-2 cells. Furthermore, Sal B and SB-431542 profoundly down-regulated the expressions of TβR-I and p-Smad2/3 but prevented the decreased expression of Smad7 in TGF-β1 stimulated HK-2 cells.Conclusions: Sal B can prevent tubular EMT in the fibrotic kidney induced by HgCl2as well as HK-2 cells triggered by TGF-β1, the mechanism of Sal B is closely related to the regulation of TGF-β1/Smads pathway, manifested as the inhibition of TGF-β1 expression, suppression of TβR-I expression and function, down-regulation of Smad2/3 phosphorylation, and restoration of the down-regulation of Smad7, as well as inhibition of MMP-2 activity. © 2010 Wang et al; licensee BioMed Central Ltd.

Salvianolic acid B (Sal B) is a water-soluble compound found in the traditional Chinese medicine, Radix Salviae miltiorrhizae, and has been widely used to treat a variety of diseases in Asian cultures. Sal B was shown to inhibit apoptosis in many cell types, but its effect on hepatocyte apoptosis is unknown. In this study, we attempt to show that Sal B attenuates hepatocyte apoptosis and hepatic injury induced by lipopolysaccharide and D-galactosamine in mice. Sal B also inhibits apoptosis that is induced by the death receptor in the HL-7702 hepatocyte cell line. Apoptosis in vitro is determined by flow cytometry, DNA electrophoresis and high content screening assay. The antiapoptotic effect is generated by reducing the expression of tumor necrosis factor α receptor type 1, balancing the expression of Bcl-2 family members, decreasing the release of cytochrome C from the mitochondria into the cytosol and inhibiting activated Caspase-3. These findings suggest that Sal B can effectively inhibit hepatocyte apoptosis as well as the underlying mechanisms related to regulating mediators in death receptor and mitochondrial pathways.

The contraction of hepatic stellate cells (HSCs) has a critical role in the regulation of intrahepatic vascular resistance and portal hypertension. Previous studies have confirmed that salvianolic acid B (Sal B) is effective against liver fibrosis. In the present study, we evaluated the effect of Sal B on portal hypertension and on HSCs contractility. Liver cirrhosis was induced in rats by peritoneal injection of dimethylnitrosamine and the portal pressure was measured. HSCs contraction was evaluated by collagen gel contraction assay. Glycerol-urea gel electrophoresis was performed to determine the phosphorylation of myosin light chain 2 (MLC2). F-actin stress fiber polymerization was detected by fluorescein isothiocyanate-labeled phalloidin. Intracellular Ca 2+ and RhoA signaling activation were also measured. Sal B effectively reduced the portal pressure in DMN-induced cirrhotic rats. It decreased the contraction by endothelin-1 (ET-1)-activated HSCs by ∼66.5% and caused the disassembly of actin stress fibers and MLC2 dephosphorylation. Although Sal B reduced ET-1-induced intracellular Ca 2+ increase, blocking Ca 2+ increase completely by BAPTA-AM, a Ca 2+ chelator, barely affected the magnitude of contraction. Sal B decreased ET-1-induced RhoA and Rho-associated coiled coil-forming protein kinase (ROCK) II activation by 66.84% and by 76.79%, respectively, and inhibited Thr 696 phosphorylation of MYPT1 by 80.09%. In vivo, Sal B lowers the portal pressure in rats with DMN-induced cirrhosis. In vitro, Sal B attenuates ET-1-induced HSCs contraction by inhibiting the activation of RhoA and ROCK II and the downstream MYPT1 phosphorylation at Thr 696. We consider Sal B a potential candidate for the pharmacological treatment of portal hypertension. © 2012 USCAP, Inc All rights reserved.
