Objective To characterize the alteration in peripheral blood endothelial progenitor cells (EPCs) of patients with systemic lupus erythematosus (SLE).Methods Venous blood samples were obtained from 82 female patients with SLE aged (35 ± 10) years and 50 healthy female controls aged (35 ± 13) years.ACL 9000 automated coagulation analyzer was used to determine the level of Von Willebrand factor antigen (vWF Ag).Flow cytometry was performed to detect peripheral blood EPCs and circulating endothelial cells (CECs).Analysis of variance was performed to assess the differences in these parameters between patients with active and stable SLE and the controls,and Pearson correlation analysis was conducted to evaluate the relationship between these parameters.Results The number of CD34+ cells,CD133+ cells and CD34+CD133+cells per 200 000 peripheral blood mononuclear cells was 35.4 ± 16.7,86.5 ± 32.1 and 361.3 ± 176.4 in patients with active SLE,significantly higher than that in the patients with stable SLE (17.1 ± 10.9,28.7 ± 21.5,107.2 ±44.3,respectively,all P ＜ 0.01)) and the controls (13.8 ± 9.6,11.2 ± 5.5,92.3 ± 50.5,respectively,all P ＜0.01).The patients with active SLE exhibited an elevated level of vWF Ag (438.9％ ± 205.3％ vs.130.2％ ±51.5％,P ＜ 0.01),an increased number of EPCs (361.3 ± 176.4 vs.107.2 ± 44.3,P ＜ 0.01) but a similar number of CECs (127±51 vs.118 ± 39,P ＞ 0.05) per 200 000 peripheral blood mononuclear cells compared with the healthy controls.No significant differences were observed in these parameters between the patients with stable SLE and the controls (all P ＞ 0.05).The number of EPCs was positively correlated with the level of vWF Ag (r =0.67,P ＜ 0.01),but uncorrelated with the number of CECs (P ＞ 0.05) in patients with active SLE.Conclusions The quantity of EPCs in peripheral blood is closely correlated with the level of the vascular injury marker vWF Ag,hinting that the number of EPCs can serve as a useful marker of disease severity.

Objective: To optimize the sample pretreatment and establish an ultra-high-performance liquid chromatography coupled with hybrid quadrupole-orbitrap high-resolution mass spectrometry (UPLC-Q-Orbitrap-MS) assay based on the parallel reaction monitoring (PRM) mode for determination of antibiotic residues in chicken meat. Methods: Blank matrix-spiked chicken meat samples were extracted with 95% acetonitrile aqueous solution containing Na2EDTA and formic acid. The extraction solutions were cleaned up using different combinations of C18, PSA and GCB fillers, and the combinations with a higher antibiotic recovery rate was screened. The residues of 32 antibiotics were determined using UPLC-Q-Orbitrap-MS based on the PRM mode. Results: If the extraction solution was cleaned up using the C18 filler, the largest number of antibiotics with a spiked recovery rate of >80% was seen, with matrix effects of 82.2% to 112.6%. The detection limits of 32 antibiotics were 0.8 to 5.8 μg/kg, with linear correlation coefficients of >0.99, spiked recovery rates of 71.3% to 111.5% and relative standard deviations of 3.2% to 14.2%. Conclusion The UPLC-Q-Orbitrap-MS assay is suitable for determination and quantitative analysis of multiple antibiotics in chicken meat. Key words： high-resolution mass spectrometry orbitrap antibiotic residue parallel reaction monitoring

Objective To compare the mRNA expressions of interleukin (IL)-17 and IL-23 in peripheral blood of patients with psoriasis vulgaris versus healthy individuals,assess the relationship of these parameters with psoriasis area and severity index (PASI) score,and to investigate the therapeutic mechanisms of total glucosides of peony (TGP) for psoriasis vulgaris.Methods Fifty patients with psoriasis vulgaris and 40 healthy individuals were enrolled in this study.Of these patients,42 were treated with TGP of 600-900 mg twice a day for 8 weeks.Blood samples were obtained from all the healthy individuals,50 patients before treatment,42 patients after 4-week treatment,and 23 patients after 8-week treatment.Real-time fluorescence-based quantitative reverse transcription PCR (RT-PCR) was used to determine the mRNA expression levels of IL-17 and IL-23 in the blood samples.The severity of psoriasis was evaluated using PASI score before and after the treatment.Statistical analysis was done by t test,rank sum test,and Pearson correlation analysis using the SPSS16.0 software.Results The IL-17 and IL-23 mRNA expression levels (given in △Ct value) in the patients before treatment were significantly higher than those in the healthy controls (IL-17,-5.32 ± 0.80 vs.2.79 ± 0.76,t =47.71,P ＜ 0.05; IL-23,-5.43 ± 0.68 vs.-3.77 ± 0.86,t =10.38,P ＜ 0.05),and positively correlated with the PASI score (r =0.61,0.52 respectively,both P ＜ 0.05).A significant decrease was observed in the mRNA expression levels of IL-17 and IL-23 as well as PASI score in the 42 patients after 4-week treatment with TGP compared with those before treatment(IL-17,-2.24 ± 0.61 vs.-5.30 ± 0.78,t =20.40,P ＜ 0.05; IL-23,-1.97 ± 0.74 vs.-5.44 ± 0.68,t =21.69,P ＜ 0.05; PASI,5.8 ± 2.7 vs.9.4 ± 4.2,t =4.68,P ＜ 0.05),and in the 23 patients after 8-week treatment compared with those after 4-wek treatment(IL-17,-1.51 ± 0.78 vs.-2.21 ± 0.59,t =3.50,P ＜ 0.05; IL-23,-1.27 ± 0.81 vs.-1.89 ± 0.72,t =2.70,P＜ 0.05; PASI,3.8 ± 1.8 vs.7.3 ± 2.5,t =5.47,P＜ 0.05).Conclusions It seems that both IL-17 and IL-23 are involved in the pathogenesis of psoriasis vulgaris,and TGP treatment can reduce the mRNA expression levels of IL-17 and IL-23 as well as PASI score in patients with psoriasis vulgaris.

Objective To study the mechanism of effects of estrogen receptor (ER) on T and B lymphocytes in patients with SLE and synergistic effect of T and B lymphocytes in the pathogenesis of SLE.Methods Real-time fluorescence quantitative PCR was performed to detect the mRNA expressions of ER-α,interleukin 10 (IL-10) and B lymphocyte stimulator (BLyS) in peripheral blood mononuclear cells (PBMCs)from 40 SLE patients and 40 normal human controls. The clinical and laboratory correlation with the levels of these parameters was analyzed. Results A significant increase was observed in the relative expression levels of ER-α, IL-10 and BLyS mRNA in SLE patients compared with the normal human controls (P ＜ 0.05 or 0.01 ), in active SLE patients compared with inactive SLE patients (P ＜ 0.05 or 0.01 ). Additionally, the mRNA expression levels of the 3 parameters were significantly correlated with the presence of renal damage, proteinuria, arthritis, etc. No statistical difference was observed in the mRNA expression levels of these parameters between female and male patients or between female and male normal controls. Conclusions IL-10 and BLyS appear to be correlated with the disease activity and severity of SLE, and ER-α may play an important role in the action mechanism of T and B lymphocytes in SLE.
