Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Hypertensive nephropathy (HN) is a complication of hypertension. Taohongsiwu decoction (THSWD) is used clinically but its application in the prevention and treatment of HN remains unelucidated. AIM OF STUDY This study aims to explore the potential targets and molecular mechanisms of THSWD in the treatment of HN. MATERIALS AND METHODS A network pharmacology approach was used to predict the components and targets of THSWD for treating HN. Animal experiments were performed to verify the network pharmacology findings. RESULTS 205 targets were identified and regarded as potential targets of THSWD in HN treatment. Subsequently, we screened 17 hub genes and identified TP53 as the most critical one. KEGG enrichment analysis showed that p53 signaling pathway might play a significant role. In vivo experiments indicated that high-salt diets can lead to high blood pressure, kidney injury, inflammation, and fibrosis. Furthermore, the altered levels of biomarkers (Iron, malondialdehyde, catalase, ferritin, transferrin, Superoxide dismutase and Glutathione Peroxidase 4) provided evidence of ferroptosis. We found that the ferroptosis inhibitor ferrostatin-1 (Fer-1) and THSWD could significantly alleviate HN by suppressing ferroptosis. THSWD and Fer-1 treatment downregulated the protein and mRNA expression of p53, p21, RB, and CTNNB1, which were upregulated by high salt. Meanwhile, THSWD and Fer-1 reversed the downregulation of Nrf2 caused by high-salt diet. CONCLUSIONS Our results suggested that THSWD attenuate HN induced by a high-salt diet through inhibiting ferroptosis via the p53/Nrf2/p21 pathway.

Gao M, Zhang Z, Zhang Y, Li M, Che X, Cui X, Wang M, Xiong Y. Steamed Panax notoginseng attenuates renal anemia in an adenine-induced mouse model of chronic kidney disease. JOURNAL OF ETHNOPHARMACOLOGY 2022; 288:114941. [PMID: 35007683 DOI: 10.1016/j.jep.2021.114941] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/28/2021] [Revised: 11/02/2021] [Accepted: 12/22/2021] [Indexed: 06/14/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Panax notoginseng (PN) (Burk.) F. H. Chen is a medicinal herb used to treat blood disorders since ancient times, of which the steamed form exhibits the anti-anemia effect and acts with a "blood-tonifying" function according to the traditional use. However, its pharmacological effect and mechanism on alleviating renal anemia (RA) are still unclear. AIMS OF THE STUDY The study aims to investigate the effect of steamed Panax notoginseng (SPN) to attenuate RA and its underlying mechanism based on the model of adenine-induced RA mice. MATERIALS AND METHODS Seventy mice were randomly divided into seven groups of ten: the control group, model group, the erythropoietin (EPO) group, the Fufang E'jiao Jiang (FEJ) group, the high-dose steamed PN (H-SPN) group, the middle-dose steamed PN (M-SPN) group, and the low-dose steamed PN (L-SPN) group. The adenine induction RA model was applied to assess the "blood enriching" function of SPN. The blood routine indexes, erythrocyte fragility, pathologic morphology of kidney tissue and the expression levels of related cytokines and proteins in the mice were detected after 3-week administration with SPN and positive drugs. RESULTS Our study provided evidences that SPN could ameliorate RA. Compared with the control group, SPN could attenuate RA by significantly increasing the numbers of peripheral blood cells (p < 0.01), improving the erythrocyte fragility (p < 0.01), and restoring the expression of EPO mRNA in the kidneys and EPO receptor mRNA in bone marrow nucleated cells. The expression of TGF-β1 mRNA was declined and the expression of HGF mRNA was significantly increased in a dose-dependent way after the treatment of SPN. Additionally, the expression of Bcl-2 and Bcl-2/Bax ratio in the kidneys were significantly increased. In contrast, there was a highly significant decrease in the expression of Bax (p < 0.01), following SPN treatment. CONCLUSION SPN could alleviate RA by promoting the overall hematopoiesis and inhibiting the progress of renal injury in mice.

Abstract
Decellularized (DC) kidney scaffold shows great potential for renal recovering. Our study explored the effect of the DC kidney scaffolds treating on chronic renal failure (CRF) through grafting them on 5/6 nephrectomized (5/6 Nx) rat kidneys compared with gelatin sponges covered the incision edges. Blood urea nitrogen and angiotensin II were significantly lower in most time in scaffold-grafted groups. Remnant kidney tumor necrosis factor-α and fibroblast growth factor in scaffold-grafted groups significantly reduced in majority of time points compared with controls. But platelet-derived growth factor-BB showed a different varied tendency, first higher in scaffold groups on week 2, 4, 6, but lower on week 8, finally no difference on week 12 compared with gelatin-sponge groups. In addition, the index of glomerular sclerosis was significantly lesser in scaffold-grafted groups, and, the accumulation of collagen III and collagen IV decreased in scaffold-grafted groups on week 6, 8, 12 compared with gelatin-sponge groups. Moreover, DC scaffolds enhanced the expression of CD133 on week 2, 6, 8, 12. In conclusion, DC kidney scaffold altered the healing response after 5/6 nephrectomy and ameliorated renal injury to some degree. Therefore, DC kidney scaffold could be a promising therapeutic method on CRF.

Biomolecules 2020; 10:biom10091317. [PMID: 32937925 PMCID: PMC7565610 DOI: 10.3390/biom10091317] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2020] [Revised: 09/02/2020] [Accepted: 09/05/2020] [Indexed: 02/07/2023] Open
Abstract
This study was designed to assess the nephroprotective effects of Pleurotus ostreatus and Agaricus bisporus aqueous extracts and carvedilol on hyperoxaluria-induced urolithiasis and to scrutinize the possible roles of NF-κB, p53, Bcl-2, Bax and Bak. Phytochemical screening and GC-MS analysis of mushrooms’ aqueous extracts were also performed and revealed the presence of multiple antioxidant and anti-inflammatory components. Hyperoxaluria was induced in Wistar rats through the addition of 0.75% (v/v) ethylene glycol in drinking water for nine weeks. The ethylene glycol-administered rats were orally treated with Pleurotus ostreatus and Agaricus bisporus aqueous extracts (100 mg/kg) and carvedilol (30 mg/kg) daily during the last seven weeks. The study showed that Pleurotus ostreatus, Agaricus bisporus and carvedilol all successfully inhibited ethylene glycol-induced histological perturbations and the elevation of serum creatinine, serum urea, serum and urinary uric acid, serum, urinary and kidney oxalate, urine specific gravity, kidney calcium, kidney NF-κB, NF-κB p65, NF-κB p50, p53, Bax and Bak expressions as well as serum TNF-α and IL-1β levels. Moreover, the treatment decreased the reduction in urinary creatinine, urinary urea, ratios of urinary creatinine to serum creatinine and urinary urea to serum urea, Fex Urea and Bcl-2 expression in kidney. In conclusion, although Pleurotus ostreatus and Agaricus bisporus extracts and carvedilol all significantly inhibited the progression of nephrolithiasis and showed nephroprotective effects against ethylene glycol-induced kidney dysfunction, Pleurotus ostreatus and Agaricus bisporus seemed to be more effective than carvedilol. Moreover, the nephroprotective effects may be mediated via affecting NF-κB activation, extrinsic apoptosis and intrinsic apoptosis pathways.

Transcriptomic analysis of the mechanisms of alleviating renal interstitial fibrosis using the traditional Chinese medicine Kangxianling in a rat model. Sci Rep 2020; 10:10682. [PMID: 32606425 PMCID: PMC7327068 DOI: 10.1038/s41598-020-67690-3] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2019] [Accepted: 06/10/2020] [Indexed: 12/16/2022] Open
Abstract
Renal interstitial fibrosis (RIF) is currently recognized as a crucial mechanism of the pathogenesis of chronic kidney disease (CKD). Kangxianling (KXL, anti-fibrin) is a traditional Chinese medicine that has been proven to significantly reduce the levels of ECM deposition and inhibit renal fibrosis.
To characterize the mechanisms and drug targets of KXL, we established a RIF rat model and treated the rats with KXL and losartan. Histological analyses validated the establishment of the RIF model and the treatment effect of KXL. Multiple levels of transcriptomic datasets were generated using lncRNA, mRNA and microRNA sequencing of kidney tissues. Functional annotations and pathway analyses were performed to unravel the therapeutic mechanisms.
A multi-level transcriptomic regulatory network was built to illustrate the core factors in fibrosis pathogenesis and therapeutic regulation. KXL and losartan significantly reduced the progression of RIF, and a better therapeutic effect was shown with higher concentrations of KXL. According to the cluster analysis results of the RNA-seq data, the normal control (NC) and high concentration of KXL (HK) treatment groups were the closest in terms of differentially expressed genes. The WNT, TGF-β and MAPK pathways were enriched and dominated the pathogenesis and therapy of RIF. miR-15b, miR-21, and miR-6216 were upregulated and miR-107 was downregulated in the fibrosis model. These small RNAs were shown to play critical roles in the regulation of the above fibrosis-related genes and could be inhibited by KXL treatment. Finally, based on the lncRNA datasets, we constructed a mRNA-lncRNA-miRNA coexpression ceRNA network, which identified key regulatory factors in the pathogenesis of kidney fibrosis and therapeutic mechanisms of KXL. Our work revealed the potential mechanism of the Chinese medicine Kangxianling in inhibiting renal interstitial fibrosis and supported the clinical use of KXL in the treatment of kidney fibrosis.

Abstract
Renal fibrosis is a common pathological change in all stages of kidney disease. Kangxianling decoction was widely used in patients with chronic kidney disease, which could improve symptoms such as poor appetite, edema, and fatigue. However, its effect on renal fibrosis remains to be studied. In this study, we investigated its effects on renal fibrosis in a rat model of 5/6 Nephrectomy (5/6 N) in vivo and in angiotensin II (Ang II)-treated rat glomerular mesangial cells (HBZY-1) in vitro. Our data showed that 5/6 N induced renal fibrosis and combined with the activation of JNK signaling, the upregulation of transforming growth factor-β (TGF-β), collagen I (Col-I) and fibronectin (FN). The administration of kangxianling decoction inhibited the activation of JNK signaling and attenuated the deposition of extracellular matrix (ECM) proteins in damaged kidneys. In HBZY-1 cells, Ang II increased the protein expression of Col-I and FN. It also activates JNK signaling and TGF-β in a time-dependent manner. Treatment of the HBZY-1 cells with kangxianling decoction blocked Ang II-induced JNK activation and ECM overproduction. Our results indicated that Kangxianling Decoction could reduce renal fibrosis, accompanied by inhibiting the production of ECM proteins and JNK, along with downregulation of TGF-β, Ang II.

Abstract
Chinese herbal medicines (CHMs) containing aristolochic acid (AA) are associated with chronic kidney disease (CKD), but some prescribed CHMs have been shown to possess renoprotective effects. We conducted a nationwide retrospective cohort study to delineate the role of prescribed CHMs on the CKD progression. Renoprotective CHM (RPCHM) was defined if a CHM contained dong chong xia cao (Cordyceps sinensis (Berk.) Sacc.), da huang (Rheum palmatum L), huang qi (Astragalus membranaceus), dan shen (Salvia miltiorrhiza Bge.), and dong quai (Angelica sinensis (Oliv.) Diels) or belonged to specific mixture herbal formulations (Yishen capsule, Saireito, or Wen Pi Tang). Subjects who had ever used AA-containing CHMs, had cancer or HIV prior to CKD diagnosis, or died within the first month of CKD diagnosis were excluded. A total of 11,625 patients were eligible subjects. The adjusted hazard ratio (aHR) for all-cause mortality was 0.6 (p < 0.001) and 0.6 (p = 0.013) among subjects receiving RPCHMs containing Angelica sinensis and those receiving other RPCHMs, respectively. For CKD-related mortality, the aHR among subjects receiving RPCHMs containing Angelica sinensis was 0.6 (p = 0.025). The use of specific RPCHMs, especially those that contained Angelica sinensis, was associated with a lower risk of mortality among CKD patients.

Abstract
This study aimed to elucidate the therapeutic effects of oral administration of intracellular melanin from Lachnum YM156 (LIM) on chronic renal failure (CRF) in mice. The cytotoxicity of LIM was evaluated using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. CRF was induced in mice by chronic dietary adenine intake. We have used this intervention to explore the effects of oral treatment with LIM (100 and 200 mg kg-1) in CRF mice. The treatment with LIM alone and a combination of Haikunshenxi capsule (HC) add LIM increased the concentration levels of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-PX), and glutathione reductase (GSH), reduced malonaldehyde (MDA) in the nephridial tissues and also reduced the nephridial levels of tumor necrosis factor (TNF)-α, interleukin-1β (IL-1β), and interleukin (IL)-6, and the activities of inducible nitric oxide synthase (iNOS). Interestingly, the HC and LIM combination produced a higher therapeutic effect than HC alone. The mechanism of the reported salutary effects of LIM in adenine-induced CRF is associated with amelioration of the adenine induced inflammation and oxidative stress. The present findings recommend that LIM is a useful natural product which can be used to enhance the protection function of HC in CRF mice.

Abstract
BACKGROUND AND PURPOSE Poly-l-glutamic acid (PG) has been used widely as a carrier to deliver anticancer chemotherapeutics. This study evaluates PG as a selective renal drug carrier. EXPERIMENTAL APPROACH 3H-deoxycytidine-labeled PGs (17 or 41 kDa) and 3H-deoxycytidine were administered intravenously to normal rats and streptozotocin-induced diabetic rats. The biodistribution of these compounds was determined over 24 h. Accumulation of PG in normal kidneys was also tracked using 5-(aminoacetamido) fluorescein (fluoresceinyl glycine amide)-labeled PG (PG-AF). To evaluate the potential of PGs in ferrying renal protective anti-oxidative stress compounds, the model drug 4-(2-aminoethyl)benzenesulfonyl fluoride hydrochloride (AEBSF) was conjugated to 41 kDa PG to form PG-AEBSF. PG-AEBSF was then characterized and evaluated for intracellular anti-oxidative stress efficacy (relative to free AEBSF). RESULTS In the normal rat kidneys, 17 kDa radiolabeled PG (PG-Tr) presents a 7-fold higher, while 41 kDa PG-Tr shows a 15-fold higher renal accumulation than the free radiolabel after 24 h post injection. The accumulation of PG-AF was primarily found in the renal tubular tissues at 2 and 6 h after an intravenous administration. In the diabetic (oxidative stress-induced) kidneys, 41 kDa PG-Tr showed the greatest renal accumulation of 8-fold higher than the free compound 24 h post dose. Meanwhile, the synthesized PG-AEBSF was found to inhibit intracellular nicotinamide adenine dinucleotide phosphate oxidase (a reactive oxygen species generator) at an efficiency that is comparable to that of free AEBSF. This indicates the preservation of the anti-oxidative stress properties of AEBSF in the conjugated state. CONCLUSION/IMPLICATIONS The favorable accumulation property of 41 kDa PG in normal and oxidative stress-induced kidneys, along with its capabilities in conserving the pharmacological properties of the conjugated renal protective drugs, supports its role as a potential renal targeting drug carrier.

Abstract
Chronic kidney disease (CKD) is a worldwide public health concern with limited treatment options. The incidence of CDK is increasing and the disease is associated with a poor quality of life and a high financial cost of treatment. Shen-Kang (SK), a traditional Chinese herbal medicine, has been used clinically in the treatment of renal diseases for decades. This study was carried out to validate the therapeutic effects of SK on renal injury induced by 5/6 nephrectomy, as well as its effects on the apoptosis of proximal tubule epithelial cells (HK-2 cells), in an aim to elucidate its mechanisms of action. For this purpose, an animal model of renal injury was created by subjecting rats to a 5/6 nephrectomy. The rats in the sham-operated and model groups received distilled water, while the rats in the SK and enalapril (EN) groups were treated with SK or EN. The levels of blood urea nitrogen (BUN) and serum creatinine (SCr) were measured. Kidney tissues obtained from the rats were stained with hematoxylin and eosin. HK-2 cells were employed to investigate the effects of SK on the apoptosis of renal proximal tubule epithelial cells induced by treatment with hydrogen peroxide (H2O2). In addition, cell viability was measured by MTT assay. Apoptotic events were monitored by western blot analysis, flow cytometric analysis and nuclear morphological anlaysis. The levels of intracellular reactive oxygen species (ROS) were measured by flow cytometric analysis with dihydroethidium staining. The results revealed that the administration of SK to 5/6 nephrectomized rats for 1 week significantly decreased the levels of SCr and BUN. The morphological observations of the kidneys also indicated the amelioration of damage to renal tissue. Treatment of the HK-2 cells with SK significantly protected the cells from H2O2-induced apoptosis, as indicated by an increase in cell viability, the decrease in the cleavage of poly(ADP-ribose) polymerase (PARP) and fewer condensed nuclei. H2O2-induced ROS production was also attenuated by treatment with SK. Of note, the increase in the levels of phosphorylated extracellular signal-regulated kinase (ERK) and phosphorylated p38 which occurred in response to exposure to H2O2 was inhibited by treatment with SK. No changes were observed in the levels of phosphorylated JNK under the same treatment conditions. Thus, the mitogen-activated protein kinase (MAPK) signaling pathways play an essential role in the development of CKD. SK alleviated renal injury in rats induced by 5/6 nephrectomy and prevented the H2O2-induced apoptosis of HK-2 cells through the MAPK signaling pathways.

Abstract
Shenkang granules (SKGs) are a Chinese herbal medicinal formula, consisting of rhubarb (Rheum palmatum L.), Salvia miltiorrhiza, milkvetch root [Astragalus membranaceus (Fisch.) Bunge] and safflower (Carthamus tinctorius L.). The aim of the present study was to investigate the effect of SKG on chronic renal failure (CRF) in 5/6 nephrectomized (5/6 Nx) rats. The rats were randomly divided into seven groups (n=10 per group) as follows: (i) 5/6 Nx (model group; 2.25 ml/kg/day normal saline); (ii) SKGL (low dose; 5/6 Nx treated with 2 g crude drug/kg/day SKG); (iii) SKGM (moderate dose; 5/6 Nx treated with 4 g crude drug/kg/day SKG); (iv) SKGH (high dose; 5/6 Nx treated with 8 g crude drug/kg/day SKG); (v) benazepril treatment group (5/6 Nx treated with 5 mg/kg/day benazepril); (vi) Shenkang injection (SKI) group (5/6 Nx with 13.3 ml/kg/day SKI); and (vii) sham-operated group (2.25 ml/kg/day normal saline). After 30 days, the levels of microalbumin, total protein, serum creatinine, blood urea nitrogen and serum lipid were found to be significantly decreased in the SKGL and SKGM rats, showing histological improvement compared with the untreated 5/6 Nx rats, as determined by hematoxylin and eosin, and Masson's trichrome staining. In addition, SKG was found to significantly improve the levels of glutathione peroxidase and reduce the damage caused by free radicals to the kidney tissues. Furthermore, SKG prevented the accumulation of extracellular matrix by decreasing the expression of collagen I and III and inhibiting the expression of matrix metalloproteinases-2 and -9 in the renal tissue, as determined by western blot analysis. SKG was also shown to decrease the concentrations of serum transforming growth factor-β1, as determined by ELISA, and kidney angiotensin II, as determined using a radioimmunoassay kit. In conclusion, SKG was demonstrated to ameliorate renal injury in a 5/6 Nx rat model of CRF. Thus, SKG may exert a good therapeutic effect on CRF.

Abstract
Carboxymethylated polysaccharide CLEP-1b was prepared from a single component (LEP-1b) of Lachnum YM281 exopolysaccharides by molecular modification with a degree of substitution (DS) of 0.286. Infrared result proved that the carboxymethylation of LEP-1b succeeded and (13)C NMR result showed that the carboxymethyl group (CH2COOH) was chemically linked to an oxygen (O) atom of the hydroxyl on C-3 of LEP-1b. LEP-1b could improve the histopathological status of kidney and significantly reduce the contents of serum creatinine (Scr) and blood urea nitrogen (BUN), and increase the contents of total protein and albumin. It could also enhance the activity of SOD, GSH-PX, CAT, GSH and decrease MDA contents in the nephridial and hepatic tissues. What's more, CLEP-1b showed more significant effects than LEP-1b at the same dosage. The research indicated that LEP-1b and CLEP-1b could mitigate the chronic renal failure of mice and the effects were closely associated with antioxidant activity.

Abstract
Chronic renal failure (CRF) is a serious disease related to increasing incidence and prevalence as well as decline in quality of life. Bu-Shen-Huo-Xue formula (BSHX), one of traditional herbal formulations, has been clinically employed to treat CRF for decades, but the mechanisms involved have not been investigated. In the present study, we investigated the effects of BSHX on some closely related parameters in 5/6 nephrectomy CRF rats. Rats with CRF were divided into five groups, namely, one control group, one enalapril group, and three BSHX treatment groups (0.25, 0.5, and 1 g/kg·d). The rats subjected to sham operation were used as a normal control. After eight weeks of treatment, BSHX significantly decreased the levels of Scr and BUN, downregulated the mRNA expression levels of TGF-β1, CTGF, NF-κB, TNF-α, and OPN, upregulated the mRNA expression of PPARγ, and reduced in situ expression of fibronectin and laminins. Histological findings also showed significant amelioration of the damaged renal tissue. BSHX protects 5/6 nephrectomy rats against chronic renal failure probably via regulating the expression of TNF-α, NF-κB, TGF-β1, CTGF, PPARγ, OPN, fibronectin, and laminins and is useful for therapy of CRF.

Abstract
OBJECTIVE To determine the mechanisms by which kangxianling (KXL) treats renal interstitial fibrosis using a customized gene chip. METHODS Twelve out of 18 specific pathogen-free sprague dawley (SPF SD) rats underwent a unilateral ureteral occlusion. These rats were then randomly assigned into either the model unilateral ureteral obstruction (UUO) or kangxianling (KXL) group. The other six rats were assigned to the sham-operated group. The UUO and sham-operated groups were given normal saline via intragastric administration, whereas the KXL group was given KXL via intragastric administration. All rats were sacrificed for renal tissue collection (i.e., left nephridial tissue), and the detection of genetic changes with the customized chip. RESULTS Compared to the sham-operated group, transforming growth factor-beta (TGF-beta), Smad2, and Smad3 genes were significantly up-regulated in the UUO group, with >1.5-fold rise (P < 0.01). The Smad7 gene was significantly reduced in the UUO versus sham-operated group, with a down-regulation of >1.5-fold (P < 0.01). In the KXL group, TGF-beta1, Smad2, and Smad3 genes were significantly reduced compared to the UUO group, with a down-regulation of >1.5-fold (P < 0.01), whereas the Smad7 gene was significantly increased compared to the UUO group, with an up-regulation of > 1.5-fold (P < 0.01). CONCLUSION It was found that KXL can significantly reduce the gene levels of TGF-beta1, Smad2, and Smad3. Immunohistochemistry findings also revealed significantly lower TGF-beta1/Smads-mediated gene transcription activity. These findings suggest that KXL may negatively regulate the TGF-beta1/Smads signal pathway to inhibit the occurrence of renal fibrosis.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Laminaria japonica is a popular seafood and medicinal plant in China, Chinese people use them as a traditional medicine for curing edema disease, a symptom of kidney diseases. MATERIALS AND METHODS The renal protective activity and mechanism of fucoidan derivatives was studied against adenine induced CKD in rats. The fucoidan derivatives were administered at dose of 50 and 150 mg/kg body weight. The serum urea nitrogen (SUN), serum creatinine (SCR) and some enzymic activity were detected. RESULTS The SUN and SCR level decreased significantly with fucoidan derivatives administration. Histopathological changes of renal tubules and interstitium were markedly alleviated by fucoidan derivatives and the mesangial areas were also greatly reduced. Alterations were observed in the activities/levels of serum enzymic (CAT, GSH-PX) and non-enzymic (GSH) antioxidants, along with high level of malondialdehyde (MDA) in the CKD rats. However, normalized lipid peroxidation and antioxidant defenses occurred with fucoidan derivatives administration. CONCLUSION This study exhibited a new mechanism of fucoidan derivatives on CKD rats, that was the samples could alleviate renal tubules, interstitium and mesangial areas mediated by replacing the electronegative content of the glomerular cells and inhibition of mesangial cell proliferation. The study also proved the mechanism of fucoidan derivatives on the CKD rats had relationship with their antioxidant activities, the samples which could enhance the activity of antioxidant enzymes and reduce the LPO level could alleviate the symptom of CKD.

Abstract
Chronic renal failure (CRF) occurring naturally in patients or induced by subtotal nephrectomy in rats induces several alterations in the cardiovascular system (CVS). However, the effect of chemically induced CRF in rats on the CVS is less well known. We induced CRF in rats by feeding adenine (0.75%, w/w, four weeks) and investigated the effect of the ensuing CRF on the systolic and diastolic blood pressure (BP) and heart rate (HR). Further, we investigated the effect of giving acacia gum (AG, 10%, w/v) in the drinking water concomitantly with adenine on the above parameters. AG has been previously shown to ameliorate the severity of CRF in humans and rats. We confirmed here that adenine-induced CRF significantly increased the plasma concentrations of urea and creatinine, and reduced creatinine clearance. Additionally, it significantly increased both systolic and diastolic BP, with no significant effect on HR. Both of these actions were significantly mitigated by AG treatment. The antihypertensive angiotenisn-converting enzyme inhibitor lisinopril (10mg/kg) was given by gavage to rats concomitantly with adenine, significantly reduced the rise in blood pressure induced by adenine. In conclusion, adenine-induced CRF in rats significantly increased BP, and this was significantly mitigated by administration of AG. Possible mechanisms of these changes and the protective effect of AG will be investigated.

Abstract
AIM OF THE STUDY Gubenquduyishen (GBQDYS) decoction, the modified remedy of a classical Chinese prescription named Liuweidihuang decoction, has been clinically employed to treat nephrotic syndrome and chronic nephritis in chronic kidney disease (CKD). The present study was designed to examine whether GBQDYS decoction has a protective effect on renal function associated with the raised level of cystatin-C (Cys-C), serum creatinine (Scr), blood urea nitrogen (BUN) and decreased Glomerular filtration rate (GFR) in stage-II CKD. MATERIALS AND METHODS A total of 68 stage-II CKD patients were randomly divided into two groups, the control group and the treatment group who received GBQDYS decoction as an additional therapy supplement. RESULTS Following up on a period of 48 months, levels of serum Cys-C, Scr, and BUN were significantly reduced by the treatment of GBQDYS decoction and GFR was elevated in the treated group. Whereas not achieved in the control group, suggesting the nephro-protective activity of GBQDYS decoction. CONCLUSIONS Taken together, these results demonstrated that GBQDYS decoction is able to protect renal function by delaying the progression of renal failure, and this may be used as an effective alternative treatment for CKD patients.
