ABSTRACT
Objective To establish the GIOP model and extract BMSCs from the rat model.We aim to in-vesitigatethe effect ofrhPTH(1-34)for inhibiting β-catenin ubiquitination when combining with Micro-CT and bio-logical technology.We also investigate the influence of rhPTH(1-34)on the GIOP.Methods Female SPF emale rats wererandomly divided into normal control group,methylprednisolone group(model group),methylpredniso-lone+saline group(blankcontrol group)and methylprednisolone+rhPTH(1-34)group(test group). The proximal femoral cancellous bone was examined by Micro-CTand histopathological Staining. The expression of Wnt10b and β-catenin protein were detected. By comparing with inducedBMP-2,BMSCs were treated withrhPTH(1-34)and stained with ALP and alizarin red.Results(1)In Micro-CT,BV/TV,Tb.Th and Tb/N decreased,whereas Tb/sp increased in the test group comparedwith model group(P<0.05).ROI three-dimensional reconstruction of trabecu-lar bone in test group showed local bone repair;(2)Wnt10b and β-cateninexpression increased in the test group compared with the model model(P<0.05),indicating that rhPTH(1-34)can enhance the transcriptional activity of β-catenin(P<0.05)and promote the expression of Wnt10b andβ-catenin(P<0.05).Conclusion The inter-vention with rhPTH(1-34)can prevent GIOP by regulating the Wnt/β-catenin signaling pathway and inhibiting GIOP progress,which can improve the microstructure of bone.
ABSTRACT
OBJECTIVE:To compare the cost-effectiveness and quality of survival among different therapeutic regimens for diabetic patients with sulfonylureas secondary failure(SSF).METHODS:The cost-effectiveness and the effects on patients life quality of four therapeutic schemes(group A: mixed-human insulin;group B:repaglinide and metformin;group C:repaglinide and acarbose;group D:glipizide,metfonmin and novolin N) were compared using cost-effectiveness analysis in pharmacoeconomics and DSQOL(diabetic patients’ score on quality of life).RESULTS:Group A showed the best clinical efficiency,with cost-effectiveness ratio significantly lower,physiological and psychological dimension scores significantly higher and social dimension score significantly lower than in all the other 3 groups,and all were of significant differences,but no significant differences were noted in therapeutic dimension score as compared with the other 3 groups.CONCLUSION:Insulin is optimal among four schemes in the treatment of diabetic patients with sulfonylureas secondary failure in the cost-effectiveness analysis, and it has the best efficacy in the improvement of patients’ physiology and psychology.
