Objectives To investigate the effects of lipoxin receptor agonist BML-111 on IFN-βand IE86 mRNA expression of macrophages infected by human cytomegalovirus (HCMV). Methods Macrophages were infected with HCMV (MOI=0.5), and the cultured cells were randomly divided into control group, HCMV group, HCMV+BML-111 group, and HCMV+MP group. The cells were collected at 0,1,2,4,8 and 12 h after infection, and the levels of IFN-βand IE86 mRNA were tested by real-time PCR. Results Compared with HCMV group, the levels of IFN-βmRNA in HCMV+BML-111 group increased significantly (P < 0.05), while the levels of IFN-βmRNA in HCMV+MP group decreased significantly (P < 0.05); Compared with HCMV group, there were no significant differences of the levels of IE86 mRNA in HCMV+BML-111 group (P>0.05), while the levels of IE86 mRNA in HCMV+MP group increased significantly (P < 0.05). Conclusion BML-111 exerts antiviral activity by promoting the expression of IFN-βmRNA at the early stage of HCMV infection.

BACKGROUND:The anti-inflammation and protective effects of lipoxin have been verified in several immunity-related disease models. Preliminary studies of our research group have shown that, lipoxin receptor agonist BML-111 has negative regulation effects on the human cytomegalovirus (HCMV)-induced immunological injury. However, the effect of BML-111 on the HCMV replication remains unclear.
OBJECTIVE:To observe the influence of lipoxin receptor agonist BML-111 on HCMV replication and proliferation in THP-1 macrophages and human embryonic lung fibroblasts.
METHODS:THP-1 macrophages were infected by HCMV AD169 strain, and were divided into three groups:mock infection, HCMV infection, HCMV+BML-111. The final concentration of BML-111 was 100 nmol/L. cells in each group were col ected at 0, 1, 2, 4, 12, 36, 48 hours, the mRNA levels of IE86 and pp65 in the THP-1 macrophages were tested by RT-PCR method. Human embryonic lung fibroblasts were infected with HCMV (MOI=0.1), and were divided into two groups:HCMV infection and HCMV+BML-111. The patho-morphous changes of human embryonic lung fibroblasts were observed under light microscope, and the cellnumber was measured. The infective virus titer changes in human embryonic lung fibroblasts were examined by plaque assay.
RESULTS AND CONCLUSION:After the macrophages were infected by HCMV, compared with the mock infection group, the mRNA levels of IE86 and pp65 in the HCMV group and HCMV+BML-111 group were increased significantly;compared with the HCMV infection group, the mRNA levels of IE86 and pp65 in the HCMV+BML-111 group were increased significantly in the early stage (within 4 hours) after infection, but the pp65 mRNA levels were decreased significantly in the medium and late stages (24-72 hours) after infection. After human embryonic lung fibroblasts were infected by HCMV, the degree of the patho-morphous in the HCMV+BML-111 group reached 100%2 days earlier than the of HCMV infection group. The infective virus titer reached the peak 2 days earlier than the HCMV infection group, but no significant difference was found between the two groups. BML-111 accelerates the replication of HCMV in the early stage of infection, but inhibits the expression of pp65 gene in the late stage. BML-111 has no impact on the proliferation of the infective HCMV titer in vitro.

Objective To investigate balanced steady-state free precession with flow-sensitive dephasing magnetization preparation (FSD-bSSFP) in the assessment of arteries of foot in diabetic patients.Methods The lower-extremity peripheral arteries of 43 diabetic patients were evaluated by FSD-bSSFP no contrast MRA and contrast-enhanced MRA (CE-MRA)in. Two experienced observers assessed the image quality, degree of venous contaminated and visibility of pedal artery branches by FSD-bSSFP and CE-MRA respectively in consensus. The signal intensity( SI), signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of the source images of both groups were measured and Wilcoxon and t tests were performed. Results The image score of FSD-bSSFP group was 2.7 ± 1.1 and CE-MRA was 2.6 ± 0.8, there was no statistical difference ( Z = 0. 134, P ＞ 0. 05 ). The image score of demonstration of the pedal artery branches and degree of venous contamination on FSD-bSSFP were 3.2 ± 0. 9 and 1.8 ± 0. 4 respectively which were superior to that of CE-MRA (2.5 ± 0.9 and 2.1 ± 0.8 respectively). Significant statistical difference existed between the two groups in demonstration of pedal artery branches ( Z = 5.246, P ＜ 0.05 ) and degree of venous contamination (Z =2.541 ,P ＜0.05). SNR of FSD-bSSFP was 148.6 ±26.7, CNR was 88.3 ± 19.0. SNR of CE-MRA was 148.5 ± 45.6, CNR was 121.0 ± 41.0. No statistical difference existed between SNR between two methods (t = 0.013, P ＞ 0.05 ). But CNR of CE-MRA was superior to that of FSD-bSSFP and significant statistical difference existed between these two methods ( t = 5.113, P ＜ 0.01 ). Conclusion FSD-bSSFP without contrast could be used in the evaluation of foot arteries in patients of renal dysfunction and diabetes.

Objective To explore the matrix effect on cyclosporine A (CsA) test by fluorescence polarization immunoassay (FPIA) and enzyme-multiplied immunoassay technique (EMIT), explain the discrepancy of external quality control results between these two methods and find the corrective action.Methods One hundred whole blood samples with various concentrations were adopted and CsA levels were detected by FPIA and EMIT.The results were compared with each other.Moreover, the influence of residual metal ions upon immunoreactions was assessed by adding Cu2+ and Zn2+.The effect of non-whole blood matrix on extraction efficiency for quality control materials and CsA calibrator was evaluated by adding identical volume of Hb-rich reagents followed with re-extraction.Results There is good correlation between results measured with FPIA(X) and EMIT(Y) methods ( Y=0.926 8X -8.115,R2 =0.996 9).Neither FPIA nor EMIT was affected by residual metal ions ( P ＞ 0.05 ). Non-whole blood matrix decreased the extraction efficiency of two methods, but it could be corrected by supplementation of the Hb-rich reagents (≥30 g/L).Conclusions Non-whole blood matrix may be the main reason for the inconsistent results measured by FPIA and EMIT methods.It could be corrected by using Hb-rich reagents.In addition,we should consider the influence of low lib on CsA test,espocially for organ transplant patients with lower Hb ( ＜30 g/L).
