Objective:To investigate serum level of vascular endothelial growth factor(VEGF)in patients with rheumatoid arthritis(RA).Methods:VEGF ELISA Quantikine kit.The serum RF level was also d etermined using Beckman Array 360.Results:The serum concen tration of VEGF was significantly higher in patients with RA than in healthy co ntrol(P<0.01).Conclusion:It suggests that VEGF is involved in the pathog enesis of RA and that measurment of serum concentration of VEGF is noninvasive, usful method for monitoring the disease activity of RA.

AIM To examine the effects of lovastatin, probucol on the intracellular cholesterol content and cholesterol efflux. METHODS With the model of foam cells through depositing the oxidized low-density lipoprotein (OXLDL) into mouse peritoneal macrophages, intracellular cholesterol content was examined by high performance liquid chromatography after the administration of lovastatin and probucol at different concentration. RESULTS The CE/TC ratios of the model group were beyond 50% and extremely higher than those of the normal and negative groups, suggesting that the model of foam cells was established triumphantly. Lovastatin decreased intracellular TC, CE and CE/TC significantly and dose-dependently. Probucol also possessed such effects on intracellular TC, CE, but no dose-dependently, and no effect on the ratio of CE/TC. CONCLUSION The results showed lovastatin might be conducive to plagues stability by increasing cholesterol efflux from the foam cells and decreasing the intracellular cholesterol content. Probucol did not have this effect although it decreased intracellular TC and CE content.

Objective To investigate the characteristics and extent of mononuclear ceils DNA damage in peripheral blood of mice fed with low dose T-2 toxin and Deoxynivalenol(DON) alone or in combination and to explore the long-term toxicity of the toxin at sub-clinical dose. Methods Eighty female Balb/c mice weighing (14.0 ± 1.5)g 3 weeks after birth were divided randomly into control group, T-2 toxin group, DON group and T-2 toxin combined with DON group according to their body weight, 20 in each group. The mice were injected intraperitoneally T-2 toxin(5 μg·kg-1·d-1), DON(20 μg·kg-1·d-1), T-2 toxin(5 μg·kg-1·d-1) combined with:DON (20μg·kg-1·d-1)respectively,control group were treated by isotonic NaCl. In 16 weeks and 21 weeks of exposure, the tail blood of the mice was collected. The comet rate, tail DNA content,tail length and tail extent moment of mouse mononuclear ceils in peripheral blood was observed using single cell gel electrophoresis(SCGE). Results ① In T-2 toxin group,tail DNA content,tail length and tail extent moment were (27.71 ± 15.85)%, (13.67 ± 5.56)μm, 4.26 ± 3.83 at 16 weeks and (28.38 ± 15.57)%, (13.83 ± 5.47)μm, 4.37 ± 3.82 at 21 weeks, all levels of the indexes increased. In the control group, the corresponding values were (11.87 ± 4.61)%, (10.59±6.70)μm, 1.34±0.98 at 16 weeks and (11.31 ± 3.94)%, (10.83 ± 7.05)μm, 1.29±1.01 at 21 weeks, the differences in the two groups were significant (all P < 0.05) ;②In DON group, the comet rate of cells, tail DNA content and tail extent moment of comet ceils were 5.62%, (28.13 ±13.31)%, 3.39 ± 2.35 at 16 weeks and 7.71%, (29.17 ± 15.12)%, 5.70 ± 4.17 at 21 weeks. In the control group, the tailing rate was 4.34% at 16 weeks and 4.38% at 21 weeks, the differences in the two groups were significant (all P < 0.05);③In the group of T-2 toxin combined with DON,the comet rate, tail DNA content, tail length and tail extent moment was 6.21%, (30.14 ± 15.48)%, (16.93± 6.58)μm, 5.54 ± 4.22 at 16 weeks and 8.17%, (30.85 ± 15.76)%, (17,21±6.45)μm, 5.70 ± 4.17 at 21 weeks. Moreover, the levels were significantly higher than that in the control group(all P < 0.05). The tail DNA content and length of comet cell tail significantly increased in the combine group compared with T-2 group or DON group(P < 0.05). Conclusions Low dose T-2 toxin or DON can definitely result in DNA damage of mononuclear cells in peripheral blood of mice. The damage induced by T-2 toxin combined with DON is severer than that caused by T-2 toxin or DON alone.
