Objective To investigate the genetic variants in the protein C (PC) and endothelial protein C receptor (EPCR) genes associated with the risk and outcome of acute respiratory distress syndrome (ARDS) patients in Chinese Han race.Methods Five tagSNPs (single nucleotide polymorphism,SNP) in the PC and EPCR genes were genotyped in patients with ARDS (n =275) and non-ARDS (n =337) in order to find the association between them in this case-control study.The SNPs were genotyped by SNPstream Beckman platform.Then,the correlation between the associated SNPs and plasma levels of activated protein C (APC) in patients with ARDS was investigated.The APC levels were measured using enzyme linked immunosorbent assay (ELISA) method.Results Association analysis rcvealed that two PC SNPs in perfect linkage disequilibrium,rs1799809 and rs1158867,were significantly associated with susceptibility to ARDS.T allele frequency of rs1799809 in ARDS patients was significantly higher than that in non-ARDS patients (OR =1.569,95% CI:1.192-2.066).And the genotype frequencies of rs1799809 were also significantly different between these two groups (P =0.007).The association remained significant after adjustment for multiple comparisons.Haplotype consisting of three SNPs in the PC gene was also associated with susceptibility to ARDS.The frequency of haplotype CCC in the ARDS samples was significantly lower than that in the non-ARDS group (P < 0.01).Moreover,ARDS patients canrying rs1799809 TT genotype showed lower serum levels of APC than patients with TC and CC genotypes (Padj =0.02).However,genotype and allele analyses of EPCR did not show any significant difference between ARDS and non-ARDS patients.Conclusions These findings indicated that common genetic variation in the PC gene was significantly associated with susceptibility to ARDS in Chinese Han race.The PC genetic variation influenced plasma concentration of APC in patients with ARDS.

Objective To establish rSAG1-IgM-ELISA with purified rSAG1 fusion protein for immunodiagnosis of toxoplasmosis. Methods The rSAG1 fusion protein was purified by Ni 2+ column. The ELISA plate was coated with different concentrations of rSAG1, reacted with pooled positive and negtive human sera. Goat anti-human IgM conjugated to horseradish peroxidase was used as the second antibody. The appropriate detecting condition of the rSAG1-IgM-ELISA assay was determined by orthogonal experiment. The reproducibility, sensitivity and specificity of the assay were assessed. Thirty-five IgM-positive and 57 IgM-negative human sera detected by the imported IgM-ELISA kit were detected with the rSAG1-IgM-ELISA. Results The purity of rSAG1 was above 90%. The appropriate detecting condition was that the coated rSAG1 was 2 5 ?g/ml, the human serum was in 1∶100 dilution, and the second antibody was in 1∶4000 dilution. The coefficient of variation (CV) value of IgM-positive and IgM-negative pooled sera were 13 8% and 7 7% respectively. The inhibition rate of the assay was 62 0% The positive correspondence rate and negative correspondence rate were 82 9% (29/35) and 91 2% (52/57) respectively,the total correspondence rate was 88 0%, compared with the imported IgM-ELISA kit. Conclusions The rSAG1-IgM-ELISA has high sensitivity and specificity, and good correspondence rate with the imported IgM-ELISA kit. It indicates that rSAG1-IgM-ELISA has potential value for early diagnosis of toxoplasmosis.

Objective To investigate the effect of different concentrations of methotrexate (MTX) on IL-17 from peripheral blood mononuclear cells(PBMCs) and To clarify the active mechanisms of MTX on RA. Methods PBMCs were isolated from heparinized blood of healthy donors or patients with RA using Ficoll-Hypaque density gradient centrifugation. The cells were pretreated with various concentrations of MTX and then stimulated by anti-human CD3/anti-human CD28 at 37℃5%CO2. The IL-17 mRAN level was detected by semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR). The supernatants were harvested and the protein level of IL-17 was tested by ELISA kit. The percentage of CD4+IL-17+cells in PBMCs was detected by flow cytometry. Results For the four different concentrations of MTX groups (0.1,1.0, 5, 25μg/ml), the IL-17 mRNA/GAPDH ratio(0.58±0.09,0.48±0.11, 0.50±0.09, 0.51±0.14) were lower than those of the non-drug group(0.76±0.08). Paired-t test or independent-samplet test showed significant difference between the MTX treatment group and the non-drug group(P<0.01). The level of IL-17 of the four MTX groups was(121±54)pg/ml and(104±45)pg/ml and(90±36)pg/ml and(115±41)pg/ml, which was lower than the non-drug group(370±187)pg/ml(P<0.01). The average C D4+IL-17+cell ratio was reduced, but had no statistically signficant differences(P>0.05). Conclusion MTX can decrease Th17 cells differentiation and suppress IL-17 production of PBMCs, but no association can be found between its effect on the expression of IL-17 and the concentration of MTX.

An on-line solid phase extraction-high performance liquid chromatography ( SPE-HPLC ) system was applied in the plasma pharmacokinetic study of highly active anti-cancer compound tyrosine kinase inhibitors (TEB-415) in mouse. The on-line SPE-HPLC method associated with Ultimate3000 system which was applied to the determination of the blood drug level of TEB-415 in mouse plasma. C18 column ( Venusil MP, 150 mm × 4. 6 mm, 5μm) was used as analytical column and the mobile phase consisted of acetonitrile-5 mmol/L monopotassium phosphate buffer ( pH 3 . 5 ) at a flow rate of 1 . 0 mL/min was used as the isocratic elution. An MF Ph-1 column (10 mm×4 mm, 5 μm) was used as on-line SPE column, and water and water-acetonitrile were used as the washing solvent and elution solvent respectively. The detection wavelength was set at 262 nm. The pharmacokinetic parameters were calculated by WinNonlin 5. 2 software. The linear range of the calibration curve was between 100 and 20000 μg/L, and the limit of qualification was 20 μg/L. The extraction recovery was between 90 . 5% and 94 . 6%. The RSD of intra-day and inter-day precision was less than 3. 5%. The accuracy of short-term stability, freeze-thaw stability and long-term stability were between 91. 49% and 101. 96%. After oral medication, the mean peak time (Tmax) of TEB-415 in mice was 5. 29 h, and the mean maximum concentration ( Cmax) was 3403μg/L. The area under the curve ( AUC) of TEB-415 was 24600 μg/L·h. This drug's mean half-life was 3. 84 h, and its mean retention time (MRT) was 6. 56 h. These parameters suggested that TEB-415 had appropriate rate of absorption and elimination with preferable bioavailability.

Objective: To observe the therapeutic efficacy of acupoint application at different groups of acupoints in treating bronchial asthma in remission stage. Methods:A total of 120 patients with bronchial asthma in remission stage were recruited and divided by the random number table method into acupoint application group 1, acupoint application group 2 and acupoint application group 3, with 40 cases in each group. In all the three groups, Tiantu (CV 22), Dazhui (GV 14) and Feishu (BL 13) were selected, with Dingchuan (EX-B 1) added in acupoint application group 1, Shenshu (BL 23) added in acupoint application group 2, and Gaohuang (BL 43) added in acupoint application group 3. Before intervention, one month and 3 months after intervention, clinical symptoms, peak expiratory flow (PEF) andforced expiratory volume in 1 second percentage of predicted value (FEV1%) of the three groups were observed, and their clinical efficacies were evaluated. Results: Comparing the therapeutic efficacy regarding traditional Chinese medicine symptoms and signs, after 1-month treatment, the total effective rate was 87.5% in acupoint application group 1, versus 62.5% in acupoint application group 2 and 55.0% in acupoint application group 3, and the between-group differences were statistically significant. After 3-month treatment, the total effective rate was 95.0% in acupoint application group 1, versus 70.0% in acupoint application group 2 and 65.0% in acupoint application group 3, and the between-group differences were statistically significant. After intervention, the three groups all showed significant improvements in pulmonary function with statistical significance; among the three groups, the improvement in acupoint application group 1 was more significant than that in the other two groups. Conclusion: Tiantu (CV 22), Dazhui (GV 14) and Feishu (BL 13) as basic prescription plus Dingchuan (EX-B 1) can improve symptoms of bronchial asthma in remission stage, and it works better in improving pulmonary function than the basic prescription plus Shenshu (BL 23) or Gaohuang (BL 43).
