Objective To verify the flow field performance of the air dynamic wind tunnel. Methods The performance of the flow field was evaluated by testing the flow speed of sample-point on the sample-transect of the tunnel. Results Among the flow range of the tunnel, the relative deviations of the speeds of each sample-point on the sample-transect were less than 10%. When the flow rate was set, the relative deviations of the sample-transect average speed in different test period were less than 10%. The ratio of average wind velocity of upper reach to down reach of the tunnel was between 0.92 and 1.03. Conclusion The flow field of the air dynamic wind tunnel is even, stable and coincident.

Objective: To investigate quantification of expression of LTB4 inducing IL-1? and TNF-? at mRNA level in synovial membrane cells of rheumatoid arthritis. Methods: Primary cultured synovial cells from RA patients were treated with exogenous LTB4,MK-886(inhibitor of 5-lipoxygenase activating protein) and Bestatin(inhibitor of leukotriene A4 hydrolase) in the presence of LIT respectively, expressions of TNF-? and IL-1? were detected at mRNA level by Real-time Quantitative PCR. Results: Expressions of basic TNF-?(TNF-?/GAPDH) and IL-?(IL-?/GAPDH) at mRNA level in primary cultured synovial cells were 0.02?0.00 and 0.16?0.01 respectively. LTB4(10~ -9 mol/L-10~ -8 mol/L) was shown to induce dose-dependent increase of mRNA expression of TNF-?.(7-15 times) and IL-1? (1 time) , endogenous product of LTB4 by LIT significantly increased mRNA expressions of TNF-? (145 times) and IL-1?(12 times) respectively. LIT-treated synoviocytes with addition of MK-886 (5-LOX exciting protein FLAP inhibitor) (1-10 ?mol/L) were inhibited to secrete LTB4 dose-dependently, following the markedly down-regulated expressions of TNF-? (15%-66%) and IL-1? (41%-71%) at mRNA level . Bestatin(100 mg/L) could also remarkably diminish LTB4-induced mRNA expressions of TNF-?(86%) and IL-1?(79%). Conclusion: LTB4 of synovial membrance cells in rheumatoid arthritis could induce expressions of TNF-? and IL-1? at mRNA level, and their expression at mRNA level had been quantified successfully. It is a beneficial help to quantify all kinds of cytokines in methodology.

Objective To explore the composition situation of the risk factors of patients with stroke in Huainan area. Methods 471 continuous registration and hospitalized patients with stroke in Huainan were selected,of which,362 cases were ischemic stroke,109 cases were hemorrhagic stroke,and the known risk factors were statistically analyzed. Results Of all patients,the incidence of hypertension was first(69. 3% was in ischemic stroke, 77. 9% was in hemorrhagic stroke) ,and hypertension was the most important risk factors. The composition of risk factors in stroke patients of different gender were different,and the smoking,drinking problem was more prominent in male patients (51.1% ,33.2%respectively)than that in female patients(5.1% ,2.0% respectively) (x2 =111-81,67.62, all P＜0.01) ;The incidence of diabetes, heart disease, atrial fibrillation was higher in female patients (37. 6% ,31. 9% ,19.3%respectively) than that in male patients (22.3% ,20.4% ,8.8% respectively) (x2 = 13. 12,8.09,11. 12,all P＜0.01). Hypertension,diabetes accounted for only 40.8% and 47.4% of patients taking regular medication. Atrial fibrillation was more common in patients with hemorrhagic stroke. Conclusion Controlling blood pressure and blood sugar was still important in the primary prevention and secondary prevention of stroke in the region. People of different gender should be targeted for individual health education, and promoting a healthy lifestyle should be paid attention, so as to the occurrence of stroke could be effectively prevented.

Objective To comparatively investigate the characteristics of bone metabolism in forelimb malformation WHBE rabbits based on the OPG/RANK/RANKL system.Methods Healthy male 2-2.5-month old WHBE rabbit ( HWR) , Healthy Japanese rabbit ( HJR) and forelimb malformation WHBE rabbit ( FMWR) were used in this study and divided into 3 groups, HWR, HJR and FMWR groups, with 10 rabbits in each group.The shape of forelimb and mean gray value observed from X-ray film were examined, and the bone tissue micro-morphology was analyzed using HE staining.Re-al-time fluorescence quantitative PCR was used to determine the expression of osteoprotegerin ( OPG) and receptor activator of NF-KB ligand ( RANKL) mRNA.The expressions of OPG, receptor activator of NF-KB ( RANK) and RANKL protein in serum and bone tissue were assayed by enzyme-linked immunoassay ( ELISA) and immunohistochemistry, respectively. Results Compared with the HWR and HJR groups, rabbits in the FMWR group appeared abnormal in toutuous forelimb and thinner bone cortex.The mean gray values of X-ray in the FMWR group were lower than that in the HWR group ( P<0.05).There were significant differences between the FMWR and healthy rabbits (HWR and HJR) in the following pa-rameters:RANKL mRNA expression and RANKL/OPG mRNA ratio in the liver(P<0.05, P<0.01), serum protein expression of RANK and RANKL and RANKL/OPG ratio (P<0.05, P<0.01), and positive index of expression of RANKL protein and RANKL/OPG ratio in the bone tissue(P<0.05, P<0.01).Furthermore, the gene expression lev-els of OPG and RANKL of HWR were significantly higher than that of HJR(P<0.05, P<0.01).Conclusions The FMWR show some abnormal symptoms in bone metabolism as well as decrease of bone quality and histological changes of bone micro-structure, due to the significant increase of RANKL/OPG ratio of FMWR.The breed differences between WHBE and Japanese rabbits in RANKL mRNA expression level may be one of factors inducing limb malformation in the WHBE rabbits.
