Objective To explore the immunologic composition and T cell function of rhG-CSF mobilized peripheral blood grafts(G-PB) and rhG-CSF primed bone marrow grafts(G-BM) after being mixed in different proportions.Methods T cell subgroups,dendritic cells(DC) and its subsets in G-PB and G-BM were analyzed by multicolor flow cytometry.Immunologic composition of G-PB and G-BM after mixture in different proportions were calculated,lymphocyte proliferation ability and quantities of interleukin-4(IL-4),interferon-?(IFN-?) secretion by T cells in mixture grafts were determined using MTT and sandwich ELISA assays.Results After co-incubation of G-PB with G-BM in different proportions,T cell proliferation in mixture grafts was lower than that of NG-BM and G-PB(P

Aim To observe the changes on the expression of ?-SMA in rats with adriamycin-induced nephrothy and intervention of Valsartan. Methods The model group were made by unilateral nephrectomy with twice-adriamycin injections by caudal vein. Immunohistochemical method, flow cytometry and pathologic image analysis were used to observe the expression of ?-SMA, FN and LN in rats. Results The expression of ?-SMA was positive in the model group. Rates of positive cell and protein semi-quantitative analysis were more higher than the sham group(P

Objctive To explore the relationship between the expression of Fas/FasL and the apoptosis occurs in retinal ischemia/reperfusion injury of rats, as well as the therapeutic effects of bFGF on the ischemic retina. Methods The models of retinal ischemia/reperfusion injury was made by transient elevating introcular pressure. A total of 28 rats were divided into normal and operation group.The latter were subdivided into 1 hour, 6, 12, 24, 48 and 72 hours after reperfusion group, in which the left eyes of the rats were in the ischemia/reperfusion groups and the right ones were in the treatment groups (bFGF intracameral injection). Apoptosis was assessed by the terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick-end labelling (TUNEL) method, and the expression of Fas and Fas ligand was studied by strept avidin-biotin complex (SABC)immunohistochemistry. Results No positive cells were observed in the normal rats′ retinae, but there was a significant number of TUNEL positive cells in 6-24 hours after transient ischemia followed by a decrease at the 48th hour. The number of TUNEL positive cells reached a maximum at the 24th hour after ischemia. The expression of Fas gradually increased as early as when it was at the 6th hour, reached a peak at the 24th hour, and then decreased at the 48th hour. Similarly, the expression of Fas ligand was at peak in 24-48 hours in GCL and INL of retina. Conclusions Retinal ischemia-reperfusion after transient elevated IOP induced apoptosis of cells in the retina. Fas/FasL may play an important role in the early events of the apoptotic pathways. bFGF can rescue RGCs from retinal ischemia/reperfusion injury through downregulation of the expression of Fas/FasL and may represent an important mechanism for therapeutic neuroprotection.

Objective To explore the difference of immunological characteristics between recombination human granulocyte colony-stimulating factor(rhG-CSF)mobilized peripheral blood grafts(G-PB)and steady-state bone marrow grafts(SS-BM).Methods From April to October 2003,G-PB and SS-BM of 15 related donors were collected.T cell subgroups,dendritic cells(DC),monocytes and the expression of CD28 costimulatory molecules on T cells were determined by multicolor flow cytometry.The lymphocyte proliferation ability and the quantities of interleukin-4(IL-4)and interferon-?(IFN-?)secreted by T cells were determined using MTT assays and sandwich ELISA.Results The absolute numbers of monocytes,CD3+,CD4+ and CD8+ T cells,and the ratios of CD4/CD8 in G-PB were significantly higher than those in SS-BM,respectively(P0.05).The quantities of IFN-? and IL-4 secreted by T cells per micromilter in G-PB was significantly higher than those in SS-BM(P0.05).The absolute numbers of DC1 and DC2 in G-PB were significantly higher than those in SS-BM(P0.05).Conclusion It is concluded that the difference of immunological characteristics between G-PB and SS-BM may explain the lower incidence of GVHD and lower relapse rate after SS-BM and G-PB transplantation.

Objective The article aimed to investigate the correlation of lipid profile levels with deoxyribonucleic acid (DNA) damage and total antioxidant capacity (TAC) levels in obese pregnant women. Methods Healthy pregnant women (n=120 ) who took routine prenatal care from August 2011 to August 2012 in our hospital were recruited .All the pregnant women were di-vided into normal weight group ( n =45 ) and obese group ( n=75 ) .The lipid profile levels , DNA damage and TAC levels of two groups were compared and analyzed , and the correlations among lipid profile levels , DNA damage and TAC levels were analyzed . Results Compared to normal weight group , obese group showed significantly higher levels of TC (P=0.000), TG(P=0.000), and LDL-c(P=0.004), but a lower level of HDL-c (P=0.006).The DNA damage and TAC level of obese group were obviously higher than those of normal weight group (P=0.000, P=0.000).The DNA damage was positively correlated with levels of TC , TG and LDL-c among obese pregnant women (r=0.23, P=0.026;r=0.26, P=0.008;r=0.19, P=0.032), and TAC level was positive-ly correlated with TG level (r=0.32,P=0.000). Conclusion Dyslipidemia, imbalance of prooxidant and antioxidant status al-ways occur to obese pregnant women .The DNA damage is positively correlated with levels of TC , TG and LDL-c among obese pregnant women, and TAC is positively correlated with TG level .
