OBJECTIVE: To study the protective effect of U83836E (lazaroids) on ischemia-reperfusion injury (IRI) in isolated rat heart. METHODS: The isolated rat heart models of IRI were developed by linking the isolated rat heart to Langendorff perfusion system. U83836E was injected in different time, the rat heart function of ischemia-reperfusion was observed. Lactate dehydrogenase (LDH) and the cardiac treponin(cTnT) content in the outflow of coronary artery, and heat shock protein70 (HSP70) of myocardial tissue were measured. RESULTS: Compared with model group of ischemia-reperfusion, in the presence of U83836E, left ventricuIar systolic pressure(LVSP), the maximum rise rate of left ventricular pressure(+dp/dtmax) were increased (P<0.01), left ventricular end diastolic pressure(LVEDP)was depressed(P<0.05), the maximum fall rate left of ventricular pressure (-dp/dtmax) was accelerated (P<0.01). The content of LDH and cTnT in effluent samples of U83836E group(A group or B group) were lower than that in model group(P<0.01), the expression of HSP70 in myocardial tissue was increased(P<0.01). CONCLUSION: U83836E has protective effect on myocardial ischemia-reperfusion injury in isolated rat heart.

Objective: To investigate the neuroprotective effects of paeoniflorin (PF) against cell death induced by hydrogen peroxide (H2O2) in human neuroblastoma cells and its mechanisms. Methods: H2O2 was used to induce SH-SY5Y cell damages, and the cell survival rate was detected by CCK-8 assay; the cell morphologic changes were observed by inverted optical microscope; the apoptosis was tested using Hoechst 33258 staining; flow cytometer (FCM) and propidium iodide staining were used to analyze the apoptosis and cell cycle alteration; reactive oxygen species (ROS) production was determined by 2', 7'-dichlorodihydrofluorescein diacetate (DCFH-DA) fluorescence; lactic dehydrogenase (LDH) release was detected by reaction of diaphorase and INT; 8-OHdG production was determined by enzyme-linked immunosorbent assay (ELISA); caspase-3 activity was determined by caspase-3 catalyzing the specific substrate. Results: Compared with control group, after the treatment with H2O2 (200 μmol/L) for 24 h, the viability and proliferation index of CH-SY5Y cells were significantly decreased (P < 0.01, 0.05), the apoptosis rate and content of 8-OHdG were increased (P < 0.01), the LDH resease and ROS production were increased (P < 0.01); the activity of caspase 3 was increased (P < 0.01). Compared with H2O2 injury group, PF (20-40 μmol/L) significantly ameliorated the changes in SH-SY5Y cells induced by H2O2 in concentration-related manner (P < 0.05). PF (10 μmol/L) did not significantly change the above indexes except the cell viability, ROS, and caspase-3 activity induced by H2O2 (P < 0.05). Conclusion: PF has the significant protective effect against the H2O2-induced cell injury, which may be related to eliminatinging ROS, alleviating DNA oxidative damage, regulation of cell cycle, and inhibition of apoptosis of caspase pathway activation.

BACKGROUND: Autoreactive T cells are a group of specialized cells that exert a peripheral immunosuppressive effectthrough certain mechanisms ensuring self-tolerance within the adaptive immune system. The discovery of the latestsurface markers for natural CD4+CD25+ regulatory T cells has re-emphasized the concept of peripheral regulation orsuppression of T cells. Several groups have begun to investigate the role of regulatory T cells in animal models ofallogeneic hematopoietic stem cell transplantation.OBJECTIVE: To review the recent results regarding protection from graft-versus-host disease by adoptively transferredCD4+ CD25+ regulatory T cells in mice and to discuss the latest findings from clinical studies on hematopoietic stem celltransplantation.METHODS: We retrieved CNKI, PubMed and Medline databases for articles concerning CD4+CD25+ regulatory T cellsand graft-versus-host disease published from 2000 to 2015. According to inclusion and exclusion criteria, 46 paperswere included in result analysis.RESULTS AND CONCLUSION: CD4+CD25+ regulatory T cells expressing the transcriptional repressor FOXP3 mediateimmunoregulatory functions and are critical for the prevention of autoimmune diseases. As peripheral tolerance inductionis a prerequisite for successful allogeneic hematopoietic stem cell transplantation, the role of CD4+CD25+ regulatory Tcells in transplantation models and clinical trials is now under investigation in many laboratories. CD4+CD25+ regulatoryT cells play an important role in the development of graft-versus-host disease after allogeneic hematopoietic stem celltransplantation. CD4+CD25+ regulatory T cells not only effectively prevent and treat graft-versus-host disease but alsoretain graft-versus-leukemia effect.

Objective: To explore an ideal method for culturing autologous chondrocytes while maintaining their cartilaginous phenotype by combining monolayer culture with three-dimensional culture. Methods: Chondrocytes were cultured by routine monolayer culture method, then the chondrocytes of fourth passage were seeded into alginate beads for three-dimensional culture following standard protocols. The cell morphology was observed by inverted microscope at predefined time points. The cell viability and proliferation were tested by trypan blue and LIVE/DEAD® Kit, respectively. And extracellular matrix formation was examined by toluidine blue staining. Results: The cartilaginous phenotype of chondrocytes could only be maintained by passage 2 and 3 after monolayer culture. Three-dimensional culture could gradually regain and maintain the cartilaginous phenotype of de-differentiated chondrocytes (P4). Cells of P1-3 by monolayer culture could maintain 90% activity, which decreased from P4. The cytoactivity of cells by three-dimensional culture method was always above 90%. The total doubling rate till P6 by monolayer culture (28 days) was 44 times that by three-dimensional culture. The staining intensity of cartilaginous extracellular matrix was significantly decreased after P4 by monolayer culture (P<0.05). For three-dimensional method, the staining intensities of cartilaginous extracellular matrix at day 21 and 28 were significantly higher than that at day 7 (P<0.05). Conclusion: Monolayer culture allows proper proliferation of chondrocytes, and following three-dimensional culture in alginate beads can regain the cartilaginous phenotype of chondrocytes, thus achieving the aim of both amplification and maintenance of the cartilaginous phenotype.
