ABSTRACT
Objective To explore the treatment and nursing intervention in heart failure, the use of cedilanid therapy. Methods In 40 cases of heart failure patients using conventional methods of intervention, and classified as the control group, the other 40 patients in the control group using Western intervention on LAN, and classified as the observation group, two groups the patients in our hospital from January 2017 to March 2015. Results The two groups of patients have found efficiency, patients in the observation group were significantly higher, the observation of patients was 92.5%, the control group was 72.5%; the two groups of patients with heart rate, blood pressure were not significantly different in the treatment before and after intervention in observation group were improved after grouping obviously better than that shows obvious differences (P<0.05). The two groups had no obvious adverse reactions. Conclusion Cediland analysis shows that in the treatment of heart failure and intervention effect, can improve the clinical situation of patients, improve the clinical treatment effect, and no significant adverse reactions, worthy of clinical reference.
ABSTRACT
Aim To study the effect of silymarin on proliferation and apoptosis of human osteosarcoma saos-2 cells and to explore its possible mechanisms .Meth-ods Control group and different concentration groups of silymarin were set , and Saos-2 cells were treated with silymarin .Celluar morphologic changes were ob-served by inverted phase contrast microscope .Prolifer-ation of cells was tested CCK-8 assay .Apoptosis rate of cells was analyzed by flow cytometry . ERK1/2、p-ERK1/2 and cleaved caspase-3 protein expression were measured by Western blot .Results Silymarin inhibi-ted the proliferation of Saos-2 cells in a time-dependent and concentration-dependent manner . Silymarin in-duced the apoptosis of Saos-2 cells in a concentration-dependent manner . Silymarin decreased p-ERK1/2 protein expression and increased cleaved caspase-3 protein expression in a concentration-dependent man-ner, while ERK1/2 protein expression had no obvious change.Conculsions Silymarin can inhibit the prolif-eration of human osteosarcoma saos-2 cells and induce apoptosis of them , and the mechanism may be related to inhibition of ERK signaling pathway and upregulated caspase-3 protein expression .
ABSTRACT
BACKGROUND:As mesenchymal stem cells are commonly used as seed cells in studies of regenerative medicine and tissue engineering, the regulatory mechanism of their biological characteristics is a current research focus. OBJECTIVE:To summarize the regulations of Wnt signaling pathway on proliferation, senescence and differentiation of mesenchymal stem cells. METHODS:PubMed database and CNKI database were retrieved by computer using the key words of“mesenchymal stem cells, Wnt signaling pathway, proliferation, senescence, differentiation”in Chinese and English, respectively, between 2002 and 2014. Final y, 44 articles were included in result analysis. RESULTS AND CONCLUSION:Wnt signaling pathway is widely involved in the regulations of the biological characteristics of mesenchymal stem cells. Canonical Wnt signaling pathway reveals a bi-directional regulation effect on cellproliferation and osteogenic differentiation, and enhances senescence and neural differentiation, but inhibits adipogenic differentiation;non-canonical Wnt signaling pathway enhances senescence and osteogenic differentiation, and inhibits proliferation and adipogenic differentiation of mesenchymal stem cells, but it takes no part in neural differentiation of mesenchymal stem cells. So the regulations of Wnt signaling pathway on the biological characteristics of mesenchymal stem cells can be used as the new therapeutic targets of bone tissue engineering, nerve injury repair, and so on.
