Objective To observe the protecting effect of Tongluoningxinfang decoction on human umbilical vein endothelial cells. Methods To cultivate endothelial cells and prepare serum with Tongluoningxinfang decoction and Fufangdanshenwan,cells were randomly separated into 8 groups,normal group,model group,treat group (high dose,medium dose,low dose),control group (high dose,medium dose,low dose). Except normal group,add 30% H2O2 to the other groups,and make endothelial cells damaged models. Add serum with drugs to treat groups and control groups,and test NO,ET-1 and P-selection (Ps) respectively. Result NO of model group was significantly lower than normal group,all treat groups and all control groups. ET-1 of model group was significantly higher than all treat groups and all control groups. Ps of model group was significantly higher than normal group,treat groups (smedium dose,low dose) and control groups (high dose,medium dose). It had no significant difference compared with model group,treat group (high dose) and control group (low dose). Conclusion Tongluoningxinfang decoction has the same influence as Fufangdanshenwan on secretion of vein endothelial cells. Tongluoningxinfang decoction and Fufangdanshenwan all can prevent vein endothelial cells from damage induced by H2O2.

Objective To investigate the possibility of conditionally induced culture medium (CICM) of oxidative damaged cardiomyocytes(CMs) derived from SD suckling rats to induce the differentiation of human bone marrow mesenchymal stem cells (hMSCs) into cardiomyo-like cells. Methods hMSCs and SD suckling rats' CMs were respectively isolated and cultured in vitro. Beating CMs were damaged by H_2O_2 and the the resultant culture medium wherein the oxidative damaged CMs were euhivated was used as CICM. Passaged hMSCs were induced by CICM for 4 weeks. The morphologies of induced hMSCs were observed by inverted microscope and the special cardio-markers-Cardiac troponin I(cTnI) and desmin were identified by immunocytochemistry method. Results After coincubation with CICM, hMSCs became larger and expressed cTnI and desmin.Conclusion CICM of oxidative injured CMs could induce hMSCs differentiation into cardiomyo-like cells.

Background Studies showed that there exsits differential gene expression in human uveal melanoma (UM).However, the researching results are somewhat inconsistently abroad, while relevant literature is still less in China.Few domestic researches have reported the abnormalities of gene transcription level or the pathways of these genes.Objective This study was to compare the gene expression profiles between human UM and normal uvea tissues and analyze the metabolic pathways involved in these differentially expressed genes.Methods Four human UM samples were collected in Beijing Tongren Eye Center,and 4 pieces of normal uveal tissues from 4 donors served as controls.The expression of genes was detected with Human Genome U133 Plus 2.0 chip,and the expression profiles were compared between two groups.The biological functions and active pathways of the genes were analyzed by Gene Ontology Enrichment Analysis Software Toolkit (GOEAST).Results Compared with the normal controls,4 165 differential genes were screened in human UM (12.50%) ,including 1 236 up-regulated genes (3.71%) and 2 929 down-regulated genes (8.79%) ,in which the genes of raised more than 5-, 10-,50-and 100-fold were 113,21,1 and 1, respectively, and the genes of reduced by 50% ,90% ,98% and 99% were 1 053,422,33 and 5,respectively.The functions of these differentially expressed genes were associated with cellular differentiation and growth,development, cell adhension, immun response, transcriptional contol, signal transduction and anti-apoptosis.The metabolic pathways of differentially expressed genes included angiogenesis pathway, cell-cycle related protein kinase pathway and immune regulatory pathway (involving B lymphocytes and T lymphocytes).ConclusionsGene expression profiles are evidently different between human UM and normal uveal tissue.The variation of the gene profiles in human UM leads to the changes of multiple biological functions including angiogenesis and kinase pathway even immun system.It is implied that the pathogenesis of human UM is a comprehensive effect of multiple genes and biological pathways.

Objective To observe whether human bone marrow mesenchymal stem cells (hMSCs) could differentiate into cardiomyo-like cells by culturing with supernatant of normal or injured rat cardiomyocytes (CMs) in vitro. Methods hMSCs were cultured with supernatant from normal or injured rat CMs for 27~30 d. The morphologies of induced hMSCs were observed with inverted microscope and the special cardio-markers cTnI and Desmin were identified with immunocytochemisry. Results A few cells cultured with supernatant from normal CMs enlarged and expressed cTnI, but little Desmin. While more cells cultured with supernatant from injured CMs enlarged and expressed cTnI, and parts of them expressed Desmin. The incidence of cTnI or Desmin positive cells were significantly different between these two groups (P<0.01). Conclusion Supernatant from both normal and injured CMs can induce hMSCs into cardio-like cells in vitro, and that from injured CMs is more effectively.
