| 1 | Effect of Cyclocarya paliurus polysaccharides on streptozotocin-induced diabetic nephropathy in rats显示文摘OBJEVTIVE:To investigate the efficacy of Cyclocarya paliurus(C.paliurus)polysaccharides on streptozotocin-induced diabetic nephropathy in rats.METHODS:Rats were divided into 6 groups,including group of normal control,group of diabetic control,group of metformin treatment,low-dose group of C.paliurus polysaccharides treatment,middle-dose group of C.paliurus polysaccharides treatment and high-dose group of C.paliurus polysaccharides treatment.Histological analysis of kidney was analyzed using hematoxilin and eosin.Levels of blood glucose,creatinine,urea,uric acid were determined by spectrophotometry.Anti-oxidative enzymes were measured by real-time polymerase chain reaction(PCR)and enzyme-linked immunosorbent assay(ELISA).Advanced glycation end products(AGEs)and transforming growth factor-β1(TGF-β1)level was measured by ELISA.RESULTS:Abnormal changes were observed in the group of diabetic control characterized by atrophy of the renal glomeruli with hypercellularity,congestion of glomerular tufts,dilation of the renal spaces,and degeneration of renal tubule.Compared with that of normal group,blood glucose,creatinine,urea,uric acid level was significantly increased in the group of diabetic control.Superoxide dismutase,catalase,glutathione peroxidase,glutathione reductase level was significantly decreased,but AGEs and TGF-β1 level was significantly increased.By contrast,administration of C.paliurus polysaccharides and metformin could reverse the above-mentioned results of the group of diabetic control,especially in the high-dose group of C.paliurus polysaccharides.CONCLUSION:Our findings suggest that C.paliurus polysaccharides may play a protecting role for nephropathy of diabetic rats by lowering glucose,creatinine,urea,uric acid level,enhancing the antioxidative ability,and reducing AGEs and TGF-β1 expression. | Xia Xichao Mao Dongxue Dai Hongmei Wu Xi Zhang Zuyuan Wang Huaying Zhou Wenwen Dong Yanmei Wang Mengqi Li Yuan Shao Xiangyang Ouyang Jingfeng | 2020 | Journal of Traditional Chinese Medicine2020，40，6： | 9 |
| 2 | Velvet antler polypeptide is able to induce differentiation of neural stem cells towards neurons in vitro显示文摘OBJECTIVE: To investigate the neural differentiation capacity of water extraction of velvet antler.METHODS: Velvet antler(Cervus Nippon Temminck) polypeptide(VAP) was used to differentiate neural stem cells(NSCs) towards neurons in the study. Firstly, we obtain the polypeptides of VAP by water extraction. Secondly, we observed the morphology, assayed the factors in the media by enzyme-linked immunosorbent assay, and detected the special neural molecules by immuno fl uorescence staining. NSCs were cultured on the cell climbing film. After neuronal differentiation, differentiated NSCs were mounted for immunocytochemistry with immunofluorescence technique.RESULTS: The differentiating cells look like neuron,some special factors, such as Glial cell line-derived neurotrophic factor, nerve growth factor, in the media can be detected while differentiated neuron-like cells can express the special neural molecules.CONCLUSION: Differentiation of NSCs towards neurons can be induced by velvet antler polypeptide. | Zhang Lihong Zhuang Zhihong Sun Yanan Ma Shuhua Yang Weifeng Lei Hongtao Zuo Junling Ouyang Jingfeng Wang Yi | 2017 | Journal of Traditional Chinese Medicine2017，37，3： | 8 |
| 3 | Efficacy of Bushenjianpi prescription on autoimmune premature ovarian failure in mice显示文摘OBJECTIVE: To assess the efficacy of Bushenjianpi prescription(BSJPP), a formula from Traditional Chinese Medicine, on a mouse model of autoimmune premature ovarian failure(POF) induced by mouse zona pellucida(ZP3) and to investigate the mechanisms underlying the action.METHODS: After randomization, POF was induced in the model mice by immunization with ZP3. One week later, mice received low(8.1 mg/kg), moderate(16.2 mg/kg) and high(32.4 mg/kg) doses of BSJPP by gastrogavage once daily for 90 days. Premarin(0.03 mg/kg) served as the positive group. Serum samples were collected 1 week after the last dose and stored at-20 ℃ for analysis. After cervical dislocation, the uterus and ovaries were collected aseptically for evaluation by histological assessment, scanning electron microscopy, immunohistochemical staining, and Western blot and reverse transcription-polymerase chain reaction analyses.RESULTS: Serum E2 levels in POF model mice were decreased, whereas follicle-stimulating hormone(FSH) and luteinizing hormone(LH) levels were dramatically increased. Serum levels of E2,LH and FSH were reduced in POF model mice treated with BSJPP(moderate and high doses) and premarin. Anti-bone morphogenetic protein 15(BMP-15) and connexin 43(Cx43) were repressed in autoimmune POF model mice, whereas high expression was observed in control mice and those treated with BSJPP(moderate and high doses)and premarin.CONCLUSION: BSJPP is effective in treating ZP3-induced POF in mice and the increase in the expression of BMP-15 and Cx43 may be implicated in the mechanism underpinning the action. | Feng Guilin Lin Meijiao Zhou Xiaolin Zhang Lihong Li Jing Ouyang Jingfeng | 2017 | Journal of Traditional Chinese Medicine2017，37，5： | 6 |
| 4 | Antioxidative and immunological effects of Cyclocarya paliurus polysaccharides on the spleen injury of diabetic rats显示文摘OBJEVTIVE:To investigate the effects of Cyclocarya paliurus(C.paliurus)polysaccharides on the spleen injury of diabetic rats.METHODS:Animals were divided into 6 groups,including normal group,model group,control group,low-dose group of C.paliurus polysaccharides treatment,middle-dose group of C.paliurus polysaccharides treatment and high-dose group of C.paliurus polysaccharides treatment.Histological analysis of spleen was analyzed using hematoxilin and eosin.Levels of biological parameters and anti-oxidative enzymes were determined by spectrophotometry.Interleukin-7(IL-7)and IL-10 were measured by enzyme-linked immunosorbent assay.RESULTS:Compared with that of model group,superoxide dismutase,catalase,glutathione peroxidase,glutathione reductase level increased 78.63%(P<0.05),51.76%(P<0.05),2.95 times(P<0.01)and 41.11%(P<0.05)in the high-dose group of C.paliurus polysaccharides treatment,respectively.IL-7 and IL-10 increase 1.66(P<0.01)and 1.21 times(P<0.01)in the high-dose group of C.paliurus polysaccharides treatment,respectively.CONCLUSION:It is suggested that C.paliurus polysaccharides may play a protecting role for spleen injury of diabetic rats by enhancing the antioxidative ability and evaluating the immunity. | XIA Xichao LI Bin QIU Ju TIAN Gang CHEN Changdong LA Ming ZHANG Ke QI Jinxu LI Yanyan GAO Huashan SHAO Xiangyang SU Congying WANG Mengqi OUYANG Jingfeng | 2021 | Journal of Traditional Chinese Medicine2021，41，5： | 2 |
| 5 | A new understanding of prescription显示文摘To promote the development of Traditional Chinese Medicine (TCM), it is necessary to innovate the traditional prescription. It is feasible to use one or several components to substitute TCM, which can be regarded as a process of discarding the dregs and preserving the essential components. In this way, traditional prescription can be converted into various combinations of pharmacological ingredients deriving from several TCMs. Furthermore, some of pharmacological ingredients should be modified to increase their efficacy. It is practical to select the main structural unit with specific substituents having strong pharmacological activity. After the innovation mentioned above, the prescription will evolve into a variety of modified components having distinct pharmacological activity, and this is the novel integration of active ingredients. | Lin Meijiao Liu Ziwang Li Jing Li Hongxing Bian Hua Si Fuchun Ouyang Jingfeng | 2019 | Journal of Traditional Chinese Medicine2019，39，5： | 1 |
