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.

Peroxisome proliferator-activated receptors (PPARs) are a family of nuclear hormone receptors belonging to the steroid receptor superfamily. Three PPAR isoforms, PPAR?, PPAR? (also known as PPAR?) and PPAR? have been found in the mouse. They can activate expression of many genes, including those involved in lipidmetabolism. PPAR? is ubiquitously expressed, but the level of expression differs markedly between different cell types. PPAR? is expressed in skeletal muscle at 10- and 50-fold higher levels compared with PPAR? and PPAR?, respectively. A role for PPAR? in skeletal muscle is to increase the genes expression with relation to oxidative metabolism. In order to determine the molecular mechanisms governing PPAR? gene expression in muscle, a 2 kb 5′ flanking region was cloned and analyzed. The DNA fragment is able to transcribe GFP in COS7 cells. Dual luciferase assay is used to quantify promoter activity. Deletion analysis of the 2 kb PPAR? promoter fragment in COS7 and NIH 3T3 cells shows that the proximal promoter sequence, nt -197 to +120, confers basal transcriptional activity of the mouse PPAR? gene. Computational analysis of putative cis-acting elements located within the ~2.0 kb mouse PPAR? 5′-flanking sequence was performed using the TRANSFAC database and MatInspector software and 4 potential MEF2A binding sites were found. And there is a potential binding site sharing 100% identity with positive element of MEF2A in the proximal promoter (nt -261). Co-transfection experiments of the PPAR? promoter reporter and pMEF2A expression plasmid (pMEF2A) showed that MEF2A significantly enhanced transcription activity of PPAR? promoter in NIH 3T3. Moreover, the enhancive effect depended on the concentration of plasmid pMEF2A transfected into cells. The results suggested that MEF2A may enhance transcription activity of the PPAR promoter in muscle cells.

Objective To develop a promising type of radiation dosimeter based on doped hydroxyapatite,and to study the stability of dosimetric characteristics indepth.Methods The samples prepared by stereotyping techniques were stored under different temperatures,humidity and illumination conditions after 60Co γ-ray irradiation.Electron spin resonance (ESR) technique was used to quantitatively measure the radiation-induced free radical signal.Results The signal change was less than 3% when the dosimeter was preserved at 4℃ or room temperature within 3 months in the experiment.At 40℃,the signal changed by about 13%,but at room temperature with the humidity less than 36%,the signal changed less than 2%.The change rose to about 8% when humidity was 76%.However,no significant decay of signal strength occurred at relatively high temperatures and under high humidity conditions.When the samples were stored under average illumination of 1600 lux or in a light-resistant container,the signal changes were less than 3.8% or 3.4% respectively.Long-term stability inspection at room temperature suggested a signal change within 4.8%.Conclusion The dosimetric properties of the material don't change significantly below room temperature in a natural environment and exhibit good stability over long-term storage.The free radical signal is not influenced drastically by relatively strong light exposure.However,a high temperature or a highly humid environment may have some effect on the measurement process,which should be taken into consideration in further applications.

Objective To detect the effects of 17 β-estradiol(E2)on the expression of Calbindin-D9k (CaBP-9k) in pituitary GH3 cells,and to investigate the antagonistic effect of a selective estrogen receptor antagonist,ⅡCI 182780 on CaBP-9k expression.Methods A rat pituitary prolactinoma cell line,GH3 cell was used as the in vitro model.The localization of CaBP-9k in GH3 cells was observed by immunofluorescence.GH3 cells were cultured with exogenous E2-added medium for 24 hours,and the concentrations of E2 were 10-8,10-9,10-10M,respectively.mRNA and protein expression levels of CaBP-9k in different groups were analyzed by RT-PCR and Western blot analysis.The estrogen receptor antagonist,and ⅡCI 182780 was added to GH3 cells before E2 administration (10-8M)with the concentration of 10-6M,in order to investigate the regulation of ER-mediated pathway on the expression of CaBP-9k.Immunoprecipitation was used to detect the interaction between CaBP-9k and ERα.Results E2 had significant stimulatory effect on the CaBP-9k expression of GH3 cells in a dose dependent manner,and the expression level of CaBP-9k was higher when treated with a higher concentration of E2.ⅡCI 182780 could suppress the stimulatory effect of E2 on the CaBP-9k expression of GH3 cells.The expression level of CaBP-9k was significantly reduced by coadministration of E2 with ⅡCI 182780 in GH3 cells,which meant the CaBP-9k expression was mediated through ERα pathway.The immunoprecipitation results further illustrated the fact that CaBP-9k could directly interact with ERα,and E2 could increase the interaction between CaBP-9k and ERα.Conclusion Estrogen might induce CaBP-9k expression via ERα mediated pathway and CaBP-9k could directly combine with ERα,suggesting that CaBP-9k might be involved in the biological effects mediated by ER pathway in GH3 cells.

Objective To investigate the detection mode for those unpaid blood donors screening as positive HBsAg+ and/or positive anti-HCV could be permitted to recall again for re-detection under the regulation condition in order to determine whether or not regain their qualifications of donating blood and rejoin the blood donation again.Methods The unpaid blood donors preliminari-ly screening as positive HBsAg and/or positive anti-HCV in Shenzhen from Otcober 2007 to December 2013 and conforming to the rules for recalling to re-detection formulated by our center were analyzed and researched for conducting the feasibility discussion on the rejoin mode of unpaid blood donors.Results A total of 415 759 case-times of blood donation were conducted during 2007 ~2013.Among them,2 506 cases(0.60%)and 1 357 cases(0.33%)were screened as positive HBsAg or positive anti-HCV,respec-tively.The recall process of rejoin re-detection was initiated in 59 positive HBsAg donors and 16 positive anti-HCV donors with many times of blood donation.But only 31 positive HBsAg donors and 9 positive anti-HCV donors successfully completed the detec-tion items of re-detection process.Among them 29 positive HBsAg donor regained the qualifications of donating blood and 2 cases were shielded for the blood donation qualification due to unqualification in the following detection.All of the 9 recalled donators with positive anti-HCV regained the blood donation qualification.Conclusion Under present detection mode,the detection tech-nique of blood screening is hard to avoid the occurrence of false positive results caused by the reagents,instruments and personnel operating.In order to protect the donation qualifications of the unpaid blood donators,a set of scientific,reasonable and practical re-detection mode for rejoin of the blood donators should be established for protecting the limited blood donation resource.
