ABSTRACT
Objective: To investigate the protective effects and possible mechanisms of Shenkang Injection (SKI) on the diabetic nephropathy in streptozotocin-induced mice. Methods: STZ with the feeding of high fat diet (HFD) was used to induce diabetic mice. The balb/c mice and diabetic mice were then randomly divided into five groups: (1) control group, (2) model group, (3) alprostadil (Alp, 1.5 μg/kg) group, (4) SKI (30 ml/kg) group, (5) Alp (1.5 μg/kg) + SKI (15 ml/kg) group. After six weeks' treatment, blood, urine and kidney tissues were collected for biochemical assay, ELISA assay, and pathological analysis. Results: Diabetic mice exhibited evident manifestations of diabetic nephropathy (DN), as indicated by increased 24-h urine volume, urinary albumin and kidney weight index (P < 0.01), which could be attenuated by SKI treatment (P < 0.01). SKI was further found to improve abnormal morphology in glomerulus with increased glomerular volume and to decrease urinary N-acetyl-b-D-glucpsaminidase (NAG), β2-microglobulin (β2-MG), and kidney injury molecules-1 (KIM-1) levels (P < 0.05, P < 0.01). Plasma levels of anti-oxidant enzymes significantly reduced in the diabetic mice, and those decreases could be reversed by SKI and Alp treatments. Additionally, SKI obviously suppressed the diabetes-induced increases of pro-inflammatory cytokines (IL-6, IL-1β and TNF-α) (P < 0.01). Meanwhile, SKI was found to effectively attenuate the diabetes-induced coagulation dysfunction, as evidenced by lengthening prothrombin and thrombin time, and decreasing plasma levels of fibrinogen (FIB), 6-K-PGF1α and thromboxane B2 (TXB2) (P < 0.05, P < 0.01). With SKI and Alp combined treatment, the anti-oxidant activities and improvements of coagulation dysfunction were enhanced. Conclusion: SKI possesses a remarkable property to prevent diabetic nephropathy. The improvements of kidney function and hypercoagulability by SKI were enhanced with Alp combined treatment. The molecular mechanisms underlying the protection of SKI against DN may be related to enhancing the anti-oxidant and anti-inflammatory activities, and improving the coagulation dysfunction.
ABSTRACT
Shenkang injection (SKI) is a classic prescription composed of Radix Astragali, rhubarb, Astragalus, Safflower, and Salvia. This treatment was approved by the State Food and Drug Administration of China in 1999 for treatment of chronic kidney diseases based on good efficacy and safety. This study aimed to investigate the protective effect of SKI against high glucose (HG)-induced renal tubular cell senescence and its underlying mechanism. Primary renal proximal tubule epithelial cells were cultured in (1) control medium (control group), medium containing 5 mmol/L glucose; (2) mannitol medium (mannitol group), medium containing 5 mmol/L glucose, and 25 mmol/L mannitol; (3) HG medium (HG group) containing 30 mmol/L glucose; (4) SKI treatment at high (200 mg/L), medium (100 mg/L), or low (50 mg/L) concentration in HG medium (HG + SKI group); or (5) 200 mg/L SKI treatment in control medium (control + SKI group) for 72 h. HG-induced senescent cells showed the emergence of senescence associated heterochromatin foci, up-regulation of P16 and cyclin D1, increased senescence-associated β-galactosidase activity, and elevated expression of membrane decoy receptor 2. SKI treatment potently prevented these changes in a dose-independent manner. SKI treatment prevented HG-induced up-regulation of pro-senescence molecule mammalian target of rapamycin and p66Shc and down-regulation of anti-senescence molecules klotho, sirt1, and peroxisome proliferator-activated receptor-g in renal tubular epithelial cells. SKI may be a novel strategy for protecting against HG-induced renal tubular cell senescence in treatment of diabetic nephropathy.

OBJECTIVE:To study the effect of Shenkang injection on the irbesartan pharmacokinetics in rats in vivo. METH-ODS:18 SD rats were randomly divided into control group(normal saline)and Shenkang injection(calculated by crude drug as 4 g/kg),9 in each group,which were intraperitoneally injected twice a day,for 7 d. After 1 h of last administration,25 mg/kg irbe-sartan was intragastrically administrated. 0.3 mL sample blood was taken in fundus venous plexus before administration of irbesartan and after 0.25,0.5,1,2,4,8,12,24,32,48,56,72,96 h of administration. Using biphenyl diester as inner standard,HPLC was adopted to determine the plasma concentration of irbesartan in plasma of rats,and pharmacokinetic parameters were calculated by using non-compartmental model in Phoenix WinNolin? 6.1 pharmacokinetic software. RESULTS:After intragastrically adminis-trated irbesartan in rats in control group and Shenkang injection group,AUC0-96 h were (28.82 ± 10.49),(35.64 ± 9.99) mg·h/L;cmax were(0.64±0.15),(0.76±0.33)mg/L;tmax were(13.07±16.70),(10.23±3.97)h;CLZ/F were(0.85±0.35),(0.63±0.21) L/(h·kg);VZ/F were (38.24 ± 24.87),(30.99 ± 9.75) mL/kg respectively,with no statistical significances (P>0.05). CONCLU-SIONS:Shenkang injection will not affect the in vivo pharmacokinetics process of irbesartan in normal dose on rats.
ABSTRACT
Objective To study the protective effect of Shenkang injection on peritoneal mesothelial cells (PMCs) of continuous ambulatory peritoneal dialysis (CAPD) mice, and explore the possible mechanism. Methods Forty ICR mice were randomly divided into blank control (A) group, peritoneal dialysis (B) group, low dose of Shenkang (C) group ( 2.5%dialysate+5 mL/kg Shenkang injection), medium (D) group (2.5% dialysate+10 mL/kg Shenkang injection) and high (E) group (2.5% dialysate+ 20 mL/kg Shenkang injection). Mice were observed for 4 weeks. Fasting blood glucose, total cholesterol, triglyceride and C-reactive protein (CRP) were detected by biochemical assay. Tumor necrosis factor-alpha (TNF-α), transforming growth factor-beta 1 (TGF-β1), vascular endothelial growth factor (VEGF) and connective tissue growth factor (CTGF) levels of serum and dialysate were detected by ELISA. Pathological changes of peritoneal tissue were observed by HE staining. Expression and mRNA transcription levels of these four cytokines in the peritoneal tissue were detected by immunohistochemical staining and real-time PCR respectively. Results There were no significant differences in body weight, fasting blood glucose, total cholesterol and triglyceride between 5 groups of mice (P>0.05). Compared with group B, there was no significant difference in CRP level between group C and group E, but which was significantly decreased in group D (P<0.05). The serum and dialysate levels of TNF-α, TGF-β1, VEGF and CTGF were decreased in group C and group D. The serum and dialysate levels of TNF-αand TGF-β1 were significantly increased in group E (P<0.05), but there was no significant difference between VEGF and CTGF in group E. Compared with group E, except for CTGF in dialysate of group C, the serum and dialysate levels of TNF-α, TGF-β1, VEGF and CTGF were significant decreased in group C and group D (P<0.05). Damaged PMCs were found in group B, which were improved in various degrees in group C, group D and group E. Compared with group B, the protein expression and mRNA relative transcription levels of TNF-α, TGF-β1, VEGF and CTGF tended to decrease gradually in group C, group D and group E (P<0.05). Conclusion A certain concentration of Shenkang injection can protect PMCs by inhibiting the expression of TNF-α, TGF-β1, VEGF and CTGF in CAPD mice, so as to control the occurrence and development of peritoneal fibrosis.
ABSTRACT
This study aimed to clarify preliminarily the effects and mechanisms of Shenkang injection (SKI) promoting extracellular matrix(ECM)degradation via regulating extracellular-signal regulated protein kinase(ERK)1/2/matrix metalloproteinases(MMPs)signaling pathway in renal failure rats. Twenty rats were randomly divided into 4 groups：the Sham group,the Model group,the SKI group and the Enalapril maleate(EM)group. The model rats with renal failure were induced by intragastric administration of adenine and unilateral ureteral obstruction(UUO). After modeling, the rats in SKI group and EM group were intervened by intraperitoneal injection of SKI or intragastric administration of the EM suspension,while the rats in Sham group and Model group were administrated with distilled water respectively for 3 weeks. The 24 h urinary protein excretion(Upro)and urinary N-acety1-β-D-glucosaminidase(UNAG)in all rats were tested after drug administration. All rats were sacrificed after drug administration for 3 weeks,blood and kidney were collected,renal morphological characteristics were observed. Furthermore,serum biochemical indices and the protein expressions of collagen type IV(CIV),MMP-2,MMP-9,tissue inhibitors of metalloproteinase(TIMP)-1,ERK1/2 and phosphorylated-ERK1/2(p-ERK1/2)in the kidney were evaluated respectively. The results indicated that,after the intervention of SKI,serum creatinine(Scr),blood urea nitrogen(BUN),uric acid(UA),albumin(Alb),Upro,UNAG and renal morphological change in model rats were improved at different levels,respectively. Moreover,these actions were similar to EM. In addition to these,SKI adjusted the protein expressions of MMP-2,MMP-9 and TIMP-1,and down-regulated the protein expressions of p-ERK1/2 in the kidney. Moreover,these actions were different from EM. In conclusion,SKI promotes ECM degradation and delays the progression of renal failure possibly through regulating ERK1/2 signaling pathway activation in the kidney and intervening MMPs/TIMP-1 expressions in vivo.

ABSTRACT
To explore the stability of Shenkang injection respectively in five different solutions to choose the best com-patibility program and improve the rational drug use. Methods:The pH value, insoluble particles and the content of protocatechuic al-dehyde in Shenkang injection were determined after mixed with five solutions. Results:In the 6-hour mixing, the change order of proto-catechuic aldehyde content was 0. 9% sodium chloride injection> 5% fructose injection> 10% invert sugar injection > 5% dextrose injection> 10% glucose injection, especially in 0. 9% sodium chloride injection, the content was decreased by 20%. The number of insoluble particles was increased after the 2-hour mixing except in 10% invert sugar injection solution, and the increase in the four so-lutions was beyond the requirement in the 2010 edition of Chinese Pharmacopoeia, and the number of insoluble particles in 0. 9% sodi-um chloride injection was the highest with the fastest change. During the experimental process, the pH value was stable. Conclusion:The five solutions show influence on stability of Shenkang injection in varying degrees. Shenkang injection in 0. 9% sodium chloride in-jection is the least stable, which should be used with caution in clinics, while invert sugar injection and glucose injection can be the best choice for Shenkang injection and the mixed solution should be used up in 2h.

ABSTRACT
This study was aimed to explore the clinical efficacy of Shen-Kang Injection (SKI) combined with hemodialysis in the treatment of chronic renal failure (CRF) patients. A total of 41 end-stage CRF patients under the hemodialysis treatment were randomly divided into the SKI treatment group of 19 cases and a control group of 22 cases. Both groups were treated with standard dialysis and the hemodialysis was maintained in the same symp-tomatic treatment conditions. Patients in the control group underwent three hemodialysis treatments in one week, while those in the treatment group were given hemodialysis twice a week based on the symptomatic treatment. And SKI was given after each time of hemodialysis in the treatment group. Indexes and changes in serum creati-nine (Scr), blood urea nitrogen (BUN) level, dialysis adequacy, nutrition status, traditional Chinese medicine ( TCM ) syndrome and other aspects of both groups were observed . The results showed that in the treatment group and control group, there were no significant differences in the renal function, dialysis adequacy, nutrition indica-tors and electrolyte ( P > 0 . 05 ) . In the treatment group , the total efficiency of TCM syndrome was 84 . 21%. And the total efficiency of TCM syndrome in the control group was 45.45%. The treatment group was better than the control group (P 0 . 05 ) . Symptoms such as fatigue , shortness of breath, poor appetite, dizziness, headache, lower back pain and spontaneous sweating were improved significantly. And there was statistical significance ( P < 0 . 05 ) . The treatment group was better than the control group . There were no abnormalities in the routine tests of blood, urine and stool, electrocardiogram, liver function, renal func-tion and electrolyte. In the treatment group, there was no significant adverse reactions during patients received SKI. The SKI has good safety. It was concluded that SKI combined with hemodialysis in the treatment of CRF is able to improve the clinical symptoms of patients and improve the patients' quality of life. When patient received adequate dialysis, SKI may reduce the dialysis frequency per week.

ABSTRACT
Objective To observe the effect of Shenkang-Ⅱ on hypothalamus-pituitary-adrenal axis (HPA axis) in nephrotic syndrome rats during high-dose glucocorticoids withdrawal, and provide a theoretical basis for clinical application of Shenkang-Ⅱ during the withdrawing and maintaining stages of glucocorticoids in the treatment of nephrotic syndrome. Methods The models of nephrotic syndrome in rats were established with adriamycin, and treated with high-dose glucocorticoid which can cause HPA axis suppression. After the HPA axis was suppressed, the hormone was reduced gradually. At the same time, the rats were treated by intragastric administration with different doses of Shenkang-Ⅱ. The changes of serum ACTH, cortisol and adrenal morphological in large dose of Shenkang-Ⅱ group, small dose of Shenkang-Ⅱ group, hormone control group, nephrotic syndrome model group and normal group were observed after two weeks. Results In the stage of withdrawing glucocorticoids, there were some amelioration in the changes of serum ACTH, cortisol in every group. After 2 weeks, those changes didn’t return to normal level. However, compared with the level of hormone control group, there were obvious increases in the levels of serum ACTH and cortisol in the large and small dose of Shenkang-Ⅱ group (P
ABSTRACT
【Objective】To observe the effect of Shenkang Pills(SP) on proliferation,extracellular matrix(ECM) secretion and cell cycle of in-vitro cultured rat mesangial cells(MC).【Methods】Sixteen Wistar male rats were randomized into 4 groups: normal serum group,Capoten(5 mg/kg) group,high-and low-dose SP(2.4 and 1.2 g/kg respectively) groups.Except the normal serum group,the rats in other groups received corresponding drugs according to the experimental design,and serum containing drug was isolated and prepared after treatment for 7 days.MC cultured with high glucose(30 mmol/L) in vitro were divided into 5 groups: A(cultured with high glucose 30 mmol/L),B(cultured with 5% normal serum),C(cultured with 5% serum containing Capoten),D and E(cultured with 5% serum containing high-and low-dose SP respectively).Another model group F(cultured with low glucose 10 mmol/L) was also established.After culturing for 72 hours,methyl thiazolyl tetrazolium(MTT) assay was used for the detection of MC proliferation,enzyme-linked immunosorbent assay(ELISA) for fibronectin(FN) content in the culture supernatant and flow cytometer for cell cycle.【Results】The proliferation of MC and FN content in supernatant were increased,and abnormal cell cycle was found in high-glucose group A.SP inhibited MC proliferation,increased the percentage of MC at G0/G1 phase,and decreased the percentage of MC at S phase and G2/M phase.【Conclusion】SP has an inhibition on MC proliferation and ECM secretion induced by high glucose,and its mechanism is probably related with the regulation of abnormal MC cell cycle.
