Objective To discuss the role of indoleamine 2, 3-dioxygenas e (IDO) and tryptophanyl-tRNA synthetase (TTS) mediated tryptophan catabolism in immune thrombocytopenia (ITP) patients treated with high doses of dexamethasone through the expressions of IDO and TTS in T cells , and the concentrations of plasma kynurenine and tryptophan. Methods 20 newly diagnosed or relapse ITP patients were treated with 40 mg/d × 4 d dose of dexamethasone. The heparin anticoagulant blood samples were obtained before treatment and the 5th day after treatment. 20 healthy subjects were selected as the control group. The IDO and TTS expressions in CD4+and CD8+ T cells were analyzed by flow cytometry. The concentrations of plasma kynurenine and tryptophan were detected by liquid-mass spectrometry system. Results Compared with healthy controls group, the plasma tryptophan and kynurenine concentration and the ratio of Kyn/Trp were significantly elevated in ITP patients (P <0.05); the IDO expressions of CD4+ and CD8+ T cells in ITP patients were significantly lower than those in healthy controls (P < 0.05), but the TTS expressions were significantly higher (P < 0.05). The concentration of tryptophan in effective group was significantly lower than before treatment (P < 0.05), in contrast, the kynurenine concentration and the ratio of Kyn/Trp were significantly higher than before (P < 0.05). The expression of IDO in effective group were significantly higher than that before treatment (P < 0.05), conversely, the expression of TTS in effective group were significantly decreased (P < 0.05). No significant difference can be found in ineffective group. Conclusion IDO/TTS-mediated tryptophan catabolism pathway could indicate the onset of ITP. The sensitivity of ITP patients with high dose of dexamethasone treatment can be observed through the level of IDO and TTS.

Objective To evaluate the validity and responsiveness of the Chinese version of the miniBalance Evaluation Systems Test(mini-BESTest).Methods A total of 208 stroke patients were evaluated by 2 professionals using both mini-BESTest and Berg balance scale (BBS).All data were analyzed using Pearson correlation,t-test and descriptive statistical analysis.Results Significant correlation was observed between each entry of the mini-BESTest and its domain,with correlation coefficients ranging from 0.78 to 0.93 (P ＜ 0.05).The scores of whole assessment and the three related domains were significantly correlated between mini-BESTest and BBS results,the correlation coefficients ranging from 0.68 to 0.87 (P ＜ 0.05).After 2 weeks of treatment,there was significant improvement in each domain and in the total assessment score (P ＜ 0.05).No floor or ceiling effects were observed in the total mini-BESTest scores,but there was a slight ceiling effect in the anticipatory and sensory orientation domains,and a slight floor effect in the reactive postural control domain.Conclusion The mini-BESTest has good validity and responsiveness,and can be applied to evaluate patients after stroke.

BACKGROUND:Under co-culture conditions, mesenchymal stem cel s could regulate osteogenic differentiation and osteogenesis of osteoblasts. OBJECTIVE:To observe the osteogenic efficiency of osteoblastic precursor cel s co-cultured with undifferentiated bone marrow-derived mesenchymal stem cel s, umbilical cord-derived mesenchymal stem cel s, or placenta-derived mesenchymal stem cel s in mineralization medium. METHODS:Adipose-derived stem cel s were induced in osteogenic differentiation medium for 7 days before being indirectly co-cultured with undifferentiated mesenchymal stem cel s isolated from different tissues (bone marrow group, umbilical cord group and placenta group) in Transwel plates. Induced adipose-derived stem cel s cultured alone served as control group. At different experimental intervals, quantitative analysis of alkaline phosphatase activity and calcified matrix was preformed to observe the effects of mesenchymal stem cel s from different sources on the osteogenic efficiency of induced adipose-derived stem cel s. RESULTS AND CONCLUSION:Expression of alkaline phosphatase was significantly higher in different experimental groups than the control group (P<0.05), and it was also higher in the bone marrow group than the umbilical cord and placenta groups (P<0.05). Quantitative analysis of calcified matrix revealed that the experimental groups were significantly higher than the control group (P<0.05);and in experimental groups, the umbilical cord group was higher than bone marrow group and placenta group (P<0.05). These findings indicate that the osteogenic efficiency of induced adipose-derived stem cel s is improved dramatical y under co-culture conditions.
