RESUMO
Objective:To explore the effect of adipose derived mesenchymal stem cells to regulate the differentiation of macrophage RAW264.7.Methods:First,we used RAW264.7 cells to simulate macrophage and induced them to M 1 macrophage with lipopolysaccharide ( LPS,1 μg/ml) .Then we cultured these RAW264.7 cells in culture mediums which were previously used to culture adipose derived mesenchymal stem cells to imitate the transplantation of ADMSC .Last,the mRNA relative expression of IL-10, IGF-1,Arg-1,TNF-α,FIZZ1,SPHK-1 was detected by real-time PCR.The protein expression of IL-12 p40,IL-27 Rα,IL-10 was detected by Western blot.Results:After been cultured in ADMSCCM and induced by LPS ,M1 markers (TNF-αmRNA,IL-12 p40;P<0.05) of the RAW264.7 cells declined while M2 markers (IGF-1 mRNA,IL-10 mRNA,IL-10;P<0.05) rose.Conclusion: ADMSC can secrete soluble cytokines to induce the RAW264.7 cell,which have been induced to the M1 macrophages,to differentiate towards M2 macrophages.
RESUMO
Objective To design a radiotherapy information system with high statistical function.Methods The whole system included foreground workstation and background database server system.The software of foreground workstation was developed under Visual C#.NET,and SQL Server 2005 was accessed by using ADO.NET.Results Radiotherapy Information System could provide basic information,diagnosis information,therapy information and follow-up information.Conclusion With Radiotherapy Information System,the management of radiotherapy information becomes more systematic and standardized.
