Effect of Extracts from Radix Ginseng,Radix Notoginseng and Rhizoma Chuanxiong on Delaying Aging of Vascular Smooth Muscle Cells in Aged Rats

Objective： To observe the effect of extracts from Radix Ginseng, Radix Notoginseng and Rhizoma Chuanxiong （EXT） on delaying vascular smooth muscle cells （VSMCs） aging in aged rats. Methods： VSMCs were obtained by the modified tissue explants technique and were shown to be positive for smooth muscle α-actin （SM-α-actin） by immunohistochemistry staining. VSMCs obtained from the young rats were served as the young control group; VSMCs obtained from the old rats were treated with no drug （the old group）, with low dose extracts （20 mg/L, the EXT low-concentration group） and high dose extracts （40 mg/L, the EXT highconcentration group）, and with Probucal （106 mol/L, the Probucal group） as a positive control. All groups were cultured for 24 h in the medium with 10% serum for 24 h followed by another 24 h in the serum-free medium. At the end of the 48-h culture, the following analyses were performed including determination of senescenceassociated β-galactosidase （SA β-Gal） activity, flow cytometry analysis of cell cycle, real-time quantitative reverse transcription polymerase chain reaction （RT-PCR） analyses of p16, Cyclin D1, cyclin-dependent kinase 4 （CDK4） and retinoblastoma （Rb） mRNA expression, and Western blotting analyses of p16, cyclin D1, CDK4 and phosphoretinoblastoma （pRb） protein expressions. Results： （1） In comparison to the younger rats, VSMCs from aged rats had significantly more SA β-Gal positive cells （P〈0.01） and more cells in S phase （P〈0.05）. VSMCs from the all treated groups showed a significant decrease in both SA β-Gal positive cells （P〈0.05） and S phase （P〈0.05） compared to the old rats. （2） Compared with the young group, VSMCs in the old group had a significant decrease in p16 and Rb mRNA expression and a significant increase in Cyclin D1 and CDK4 mRNA expression. Compared with the old group, VSMCs in the treated groups had a significant increase in p16 and Rb mRNA expression and a significant decrease in Cyclin D1 and CDK4 mRNA expression （P〈0.05）. （3） Compared with the young group, VSMCs in the old group had a significant decrease in p16 protein expression and a significant increase in Cyclin D1, CDK4 and pRb protein expressions （P〈0.05）. Compared with the old group, VSMCs in the treated groups had a significant increase in p16 protein expression and a significant decrease in cyclinD1, CDK4 and pRb protein expressions （P〈0.05）. Conclusions： VSMCs obtained from old rats showed typical signs of cellular senescence and vascular aging. EXT had an effect on delaying senescence of VSMCs in vitro by altering the p16-cyclinD/CDK-Rb pathway.

Efficacy of Sanqi(Radix Notoginseng)in treating cerebral hemorrhage in rats with traumatic brain injury

OBJECTIVE:To evaluate the protective efficacy of Sanqi(Radix Notoginseng)on cerebral hemorrhage in a rat model of traumatic brain injury(TBI)by investigating plasminogen activator inhibitor-1(PAI-1),tissue-type plasminogen activator(t-PA),nuclear factor-κB(NF-κB,p-p65),nitric oxide(NO),endothelin(ET),cluster differentiation(CD61CD62),and coagulation.METHODS:The free-fall method was used to create a rat model of TBI.Forty-eight rats were randomly divided into six groups:the blank group,sham group,model group,low-dose Sanqi(Radix Notoginseng)group,middle-dose Sanqi(Radix Notoginseng)group,and high-dose Sanqi(Radix Notoginseng)group.At 24 h after the model was created,we investigated brain MRI,brain tissue morphology using HE staining,flow cytometry,and immunohistochemical changes.RESULTS:Cerebral hemorrhage was aggravated in TBI rats(observed in brain specimens,brain MRI,and brain tissue HE).Cerebral immunohistochemistry results demonstrated that the expression of t-PA,PAI-1 and p-p65 increased significantly in TBI rats,while t-PA/PAI-1 had a significant decrease.In addition,CD61CD62,D2D,and ET were significantly increased in TBI rats,and PT and APTT were significantly prolonged;in contrast,NO was significantly decreased.Sanqi(Radix Notoginseng)decreased cerebral hemorrhage in TBI rats(observed in brain MRI and brain tissue HE),and increased t-PA/PAI-1,CD61CD62 significantly.It also significantly decreased the expression of t-PA,PAI-1,and p-p65 in brain immunohistochemistry and significantly decreased PT,APTT,D2D,and ET.However,there were no differences in NO between the model group and the Sanqi(Radix Notoginseng)group.CONCLUSION:Sanqi(Radix Notoginseng)can decrease the expression of p-p65,increase t-PA/PAI-1,and stem traumatic intracranial hemorrhage in a TBI rat model.

Blood circulation activating effect of Sanqi(Radix Notoginseng) on venous thromboembolism rats

OBJECTIVE:To explore the blood circulation activating effect and mechanism of Sanqi(Radix Notoginseng)in vivo,using a venous thromboembolism(VTE)rat model.METHODS:We established the VTE rat model,and then intervened with low molecular weight hepa-rin(LMWH),as well as low,medium and high doses of Sanqi(Radix Notoginseng),to observe the blood circulation activating effect of Sanqi(Radix Notoginseng)on VTE rats.RESULTS:After the treatment with high concentrations of Sanqi(Radix Notoginseng),the pulmonary thromboembolism was alleviated,and the lower limb thrombosis was markedly improved.Moreover,the expression quantities of plasma activated partial thromboplastin time,prothrombin time and D-dimer,as well as endothelin,von Willebrand factor,and plasminogen activator inhibitor-1 in thrombosis segment tissues were markedly down-regulated;while those of nitric oxide and tissue-type plasminogen activator were up-regulated.After low and medium concentration Sanqi(Radix Notoginseng)treatment,no obvious improvement was observed in each index.Moreover,the high concentration Sanqi(Radix Notoginseng)showed comparable efficacy to the positive drug LMWH.CONCLUSION:This data suggests that high concentration of Sanqi(Radix Notoginseng)is effective in preventing and treating VTE.

Effects of extracts from Renshen(Radix Ginseng), Sanqi(Radix Notoginseng), and Chuanxiong(Rhizoma Chuanxiong) on F-actin in senescent microvascular endothelial cells

OBJECTIVE: To investigate the effects of extracts from Renshen(Radix Ginseng), Sanqi(Radix Notoginseng), and Chuanxiong(Rhizoma Chuanxiong) on the endothelial actin cytoskeleton in senescent human cardiac microvascular endothelial cells(HCMECs), and to propose the possible mechanism underlying the actions.METHODS: Lentiviral mediated RNA interference was applied to a replicative senescent HCMEC model by knocking down heat shock protein 27(HSP27)gene. Cells were treated with extracts from Renshen(Radix Ginseng), Sanqi(Radix Notoginseng), and Chuanxiong(Rhizoma Chuanxiong) at final concentrations of 50, 100, and 200 mg/L, respectively and with 10 μM resveratrol for 48 h. Untreated cells were used as controls. Senescence was detected by senescence β-galactosidase staining and cell proliferation was analyzed by cell counting kit-8 assays.Secreted nitric oxide levels were detected by nitrate reductase. Morphological changes of F-actin and G-actin were observed by laser scanning confocal microscopy. Protein and gene expression of Factin and HSP27 was detected by western blotting.RESULTS: Compared with the control group, the proportion of senescent HSP27 shRNA cells treated with the extracts was decreased and their proliferation was increased. In the extract intervention group, F-actin around the cell periphery became irregular and jagged fractures formed gradually and then dissipated. Moreover, some dynamic actin stress fiber filaments appeared. The G-actin stretched to the cell periphery and punctate staining was scattered in the cytoplasm. In addition, the mean optical density value of F/G-actin was decreased significantly and the protein expression of F-actin was downregulated.CONCLUSION: The extracts delayed microvascular endothelial cell senescence by downregulating the expression of F-actin through HSP27.

In addition, their average recoveries were 100.28%, 105.83%, 104.09%, 99.36% and 98.54%, respectively. The relative standard deviations(RSDs) of precision, reproducibility and recovery were all less than 1.5%. The results indicate that the method is simple, accurate and reproducible so that it can be used for the simultaneous determination of the five saponins in Chinese patent medicines containing the three kinds of herbs.
