The purpose of this study was to investigate the inducible factors that stimulate the differentiation of bone marrow mesenchymal stem cells into chondrocytes. Methods: Rat BMSCs were isolated and subcultured, and then inoculated on PLGA scaffolds after successfully identificating of BMSCs. They were divided into 5 groups. Blank serum group, TGF-β1 + Yougui Yin drug-containing serum induction group, TGF-β1 + mechanical stimulation induction group, Yougui Yin drug-containing serum + mechanical stimulation induction group, TGF-β1 + Yougui Yin drug-containing serum + mechanical stimulation induction group, 4 weeks later, the adhesion status of cells and scaffolds was observed by Scanning Electron Microscopy, and then chondrocyte induction was performed on different treatment groups. After induction, the expression of Aggrecan and Collagen II was detected by immunofluorescence, and the mRNA expression of Aggrecan and Collagen II was detected by qPCR. Results: BMSCs were identified as rat bone marrow mesenchymal stem cells by immunofluorescence CD34 and CD44 cells. Scanning Electron Microscopy observed that BMSCs grew well on PLGA. Compared with PLGA group, the scaffold space of BMSCS-PLGA composite was significantly reduced, and the growth of cell adhesion scaffold was significantly increased. Compared with the blank serum group, the expression of Aggrecan in TGF-β1 + Yougui Yin drug-containing serum group and Yougui Yin drug-containing serum + mechanical stimulation group was significantly increased. The expression of Collagen II in TGF-β1 + Yougui Yin medicated serum group, Yougui Yin medicated serum + mechanical stimulation group, TGF-β1 + mechanical stimulation group and TGF-β1 + Yougui Yin medicated serum + mechanical stimulation group were significantly increased;PCR results showed that compared with blank serum group, the expression of Aggrecan in other groups was significantly increased, except for Collagen II expression in Yougui Yin drug-containing serum + mechanical stimulation group. Conclusion: BMSCs can differentiate into chondrocytes on PLGA scaffold. Compared with blank serum group, BMSCs can be induced to differentiate into chondrocytes in all induction groups, among all induction groups, TGF-β1 + Yougui-yin drug-containing serum group and TGF-β1 + mechanical stimulation group were more significant, and the difference was statistically significant.展开更多

Yougui Pill（YGP）, a 10-component traditional Chinese herbal medicine, has been shown to be clinically effective for glucocorticoid-induced suppression of the hypothalamo-pituitary-adrenal axis. However, the pharmacological and molecular mechanisms remain unclear. We hypothesized that YGP would exert an anti-apoptosis effect on dexamethasone-treated anterior pituitary cells. In vivo experiments showed that YGP significantly reduced the number of apoptotic cells, down-regulated m RNA expression of cytochrome c, caspase-3, and caspase-9, and up-regulated m RNA expression of Bcl-2. These findings suggest that YGP reduced glucocorticoid-induced apoptosis in rat anterior pituitary cells by regulating the mitochondria-mediated apoptosis pathway.展开更多

And the expressions of Nogo A,an axon growth inhibitor,and its receptor（Nogo-66 receptor,Ng R） were significantly higher than those in the normal control at the acute stage（P〈0.01）.However,after the intervention of ZGP and YGP,the pathological changes and axon damage in rats＇ brain and spinal cord were much more alleviated,and the NGF expression was significantly higher than that in the model group at the acute stage （P〈0.05）.The expression of NGF was even stronger during the remission stage,and a better effect was shown by YGP.As for Nogo A and Ng R expressions,they were significantly lower than those in the model group at the acute stage（P〈0.05）,but a better effect was shown by ZGP.Conclusions：ZGP and YGP can prevent axonal injury and promote the axonal regeneration in rats of EAE,and the possible mechanism is to increase the expression of NGF and reduce the expression of Nogo A and its receptor.However,some differences are observed between the two Chinese preparations in their acting times and points,which provides a certain basis for revealing the modern connotation of the Chinese medicine theory on tonifying Shen（肾）-yin and Shen-yang.展开更多

文摘Objective：To study the molecular mechanism of Zuogui Pill（左归丸,ZGP） and Yougui Pill（右归丸,YGP） on axonal regeneration in rats with experimental autoimmune encephalomyelitis（EAE）.Methods： EAE rat model was established by bilateral rear pedes subcutaneous injection of antigen made by mixing myelin basic protein（MBP） and complete Freud＇s adjuvant（CFA） in the volume ratio of 1：1.The pathological changes of axonal injury and regeneration in the brain and the spinal cord were observed on the 14th（the acute stage） and the 28th day（the remission stage） after modeling,with hematoxylin-eosin（HE） staining,silver stain, and immunohistochemical staining.The rats treated with prednisone acetate were taken as controls.Results： Observation under the light microscope with HE staining showed a sleeve-like change in rats＇ cerebrospinal parenchyma with inflammatory cell infiltration around the small vessels and neuronic denaturation,while silver staining showed excessive tumefaction and abscission of axon,and immunohistochemical analysis showed decreasing of nerve growth factor（NGF） expression at the acute stage of EAE,which was even more remarkable at the remission stage,showing significant difference as compared with the normal control（P〈0.05）. And the expressions of Nogo A,an axon growth inhibitor,and its receptor（Nogo-66 receptor,Ng R） were significantly higher than those in the normal control at the acute stage（P〈0.01）.However,after the intervention of ZGP and YGP,the pathological changes and axon damage in rats＇ brain and spinal cord were much more alleviated,and the NGF expression was significantly higher than that in the model group at the acute stage （P〈0.05）.The expression of NGF was even stronger during the remission stage,and a better effect was shown by YGP.As for Nogo A and Ng R expressions,they were significantly lower than those in the model group at the acute stage（P〈0.05）,but a better effect was shown by ZGP.Conclusions：ZGP and YGP can prevent axonal injury and promote the axonal regeneration in rats of EAE,and the possible mechanism is to increase the expression of NGF and reduce the expression of Nogo A and its receptor.However,some differences are observed between the two Chinese preparations in their acting times and points,which provides a certain basis for revealing the modern connotation of the Chinese medicine theory on tonifying Shen（肾）-yin and Shen-yang.
