Objective To investigate the role of indoleamine 2,3-dioxygenase(IDO)in asthma.Methods The mouse asthma model was induced by ovalbumin(OVA).IDO expression was detected on the level of protein and mRNA respectively.Distribution and maturation of dendritic cells were detected by the immunofluorescence method.Results (1)The symptoms and lung inflammation in the model group were more serious than control group.The serum total IgE was significantly higher in the model group than that in the control group,165.50 ± 30.13 ng/ml vs.94.45 ± 28.30 ng/ml(P ＜ 0.05).(2)IDO expression in the model group was lower than that in control group.On the level of protein,mean intergrated optical density was 11.38 ± 6.05 in the model group vs.23.62 ± 8.92 in the control group(P ＜ 0.05);on the level of mRNA,IDO expression of the model group was 33% of the control group(P ＜ 0.05).(3)CD11c+CD86+ cells were distributed in alveolar wall and around small vessels.The quantity of CD11c+CD86+ cells in lungs of the model group were significantly smaller than that in the control group.The median intergrated fluorescence intensity was 9961.86(range,7 406.52 ～ 12 724.98)in the model group vs.15974.60(range,10 006.39 ～ 16 171.46)in the control group(P ＜ 0.05).Conclusions IDO expression is low and matured dendritic cells are less in situ in the asthma model.These suggest that less matured DCs may produce less IDO,which may play an important role in asthma.

Objective To study the regulatory role of chemerin in infant with respiratory syncytial virus (RSV) pneumonia by investigating the level of serum chemerin,pro-inlfammatory cytokine (TNF-α, IL-17), and anti-inlfammatory cytokine (IL-10, TGF-β). Methods The serum level of chemerin,TNF-α,IL-1,IL-10,TGF-βwere tested in 82 RSV pneumonia inpatients (17 severe RSV pneumonia cases,65 mild cases) and 40 controls by ELISA and the severity of the RSV pneumonia was evaluated using a scoring system. Results The serum level of chemerin of RSV pneumonia cases were (610.45±106.63pg/ml) which were signiifcantly higher than the control(337.24±43.37 pg/ml). Chemerin level of severe RSV pneumonia group is signiifcantly higher than mild cases as well [(786.62±82.59 pg/ml)vs (539.98±65.86 pg/ml)P<0.01 ]. Signiifcant positive correlations were found be-tween serum chemerin level and TNF-α,IL-17 level (r=0.81,r=0.61;P<0.01) while the serum level of chemerin is negatively correlated with IL-10, TGF-β(r=-0.80,r=-0.75;P<0.01). Conclusions The level of chemerin increased in RSV pneumonia patients,and related to clinical severity after RSV infection. These results indicate that chemerin may play an important role in the pathogenesis of RSV pneumonia and to the severity of the infection.

Objective To observe the influence of highflux hemodialysis(HFD)on homocysteine(Hcy) level and major cardiovascular events of maintenance hemodialysis (MHD) patients. Methods Patients eligible for inclusion were randomly divided into HFD group and low flux hemodialysis(HD)group with 30 cases in each group. Patient′s serum homocysteine (Hcy),major cardiovascular events and various clinical indicators were observed for 12 months then the data were analyzed. Results Hcy baseline levels in 2 groups(21.02 ± 11.79 mmol/L vs. 19.86 ± 6.97 mmol/L)indicated no significant difference(P = 0.162)before hemodialysis but Hcy levels had significant difference(20.29 ± 11.45 mmol/L vs. 24.57 ± 13.23 mmol/L),(P=0.045)after 12-month observation. There was lower incidence of major cardiovascular events in HFD when compared to that in HD group (10.0% vs. 33.3%) which showed significantly statistical difference (P=0.034),and there was no mortality in HFD group but 1 case of death in HD group. All-cause mortality in 2 groups showed no significant difference (P > 0.05). Conclusion Long-term HFD treatment significantly reduces Hcy levels and the incidence of major cardiovascular events of MHD patients

BACKGROUND: In recent years, the immunoregulatory effects of mesenchymal stem cells (MSCs) can be used to induce immune tolerance. OBJECTIVE: To evaluate the safety and feasibility of human umbilical cord-derived MSCs (hUC-MSCs) in liver transplantation patients. METHODS: hUC-MSCs were cultured and identified. After approved by the Medical Ethics Committee, a total of 50 patients were randomly divided into experimental group and control group according to the proportion of 1:1. In the experimental group, hUC-MSCs were perfused by the portal vein during the operation and infused into the jugular vein on the 3rd day after the operation. The injection dose was 1×106/kg (prepared as 50 mL of cell suspension). Both groups received standard immunosuppressive regimens. Blood biochemistry and immune function indicators were detected preoperatively and at postoperative days 3, 7, months 1, 2, 3, 6, 12. Acute and chronic rejection rates, incidence of infection, and incidence of transplantation-related complications were recorded. RESULTS AND CONCLUSION: (1) At 3 and 7 days after the operation, the percentage of peripheral blood CD4+CD25+ cells (regulatory T cells) in the experimental group was significantly higher than that in the control group (P < 0.05). The percentage of CD4+ cells (helper/inducer T cells) and ratio of CD4+/CD8+ T lymphocytes were significantly lower in the experimental group than the control group (P < 0.05). (2) There was no significant difference in postoperative alanine aminotransferase and total bilirubin levels between the two groups (P > 0.05). (3) The incidence of abnormal liver function in the experimental group was significantly lower than that in the control group (P < 0.05). (4) The incidence of transplantation-related complications and the rate of infection showed no significant difference between the two groups (P > 0.05). Overall, the intravenous infusion of hUC-MSCs is safe and feasible in liver transplantation patients, which in early stage can promote the the proliferation and activation of CD4+CD25+ cells (regulatory T cells), reduce the percentage of CD4+ cells (helper/inducer T cells) and lower the ratio of CD4+/CD8+ T cells, thereby improving the immune status in liver transplantation patients.
