Quercetin is a herbal flavonoid derived from various foods of plant origin and plays a role in anti-inflammation. Although a number of researches in the field have been done, the mechanism of anti-inflammatory effect of quercetin should be further darified. In the present study, we investigated the effects of quercetin on IL-6 production by LPS-stimulated neutrophils in human. Neutrophils were were pre-treated with quercetin at the final concentrations of ranging from 0-80 ~M for 30 rain, or not treated, and then incubated in the presence or absence of lipopolysaccharide （LPS） at a final concentration of 100 ng/ml for indicated time. The secretion level of IL-6 in the culture supernatants was assayed by EliSA, the intracellular level of IL-6 was detected by flow cytometry and the expression of IL-6 mRNA was analyzed by RT-PCR. The experiment results showed that neutrophils cultured with medium or quercetin alone did not express IL-6, but LPS （100 ng/ml） induced IL-6 expression of neutrophils. However, after pre-treatment of neutrophils with quercetin （40 ~Vl） for 30 rain, the inducible effects of LPS on the increase of IL-6 secretion, intracellular IL-6 level and IL-6 mRNA expression by neutrophils were abrogated. IL-6 is one of the important pro-inflammatory factors, especially in early phage of inflammation. Thus, our data suggested that quercetin might exert its anti-inflammatory effect through negatively modulating pro-inflammatory factors, such as IL-6. The inhibitory effects of quercetin on IL-6 production by neutrophils may provide a theoretical basis on future therapy of inflammation. Cellular ＆ Molecular Immunology. 2005;2（6）：455-460.

In order to improve the accuracy for quantitating the bovine foamy virus (BFV) in vitro,we developed a baby hamster kidney cell (BHK)-21-derived indicator cell line containing a plasmid that encodes the firefly luciferase driven by the BFV long terminal repeat promoter (LTR,from-7 to 1012).The BFV titer could be determined by detecting the luciferase expression since the viral trans-activator BTas protein activates the promoter activity of the *** clone,designated BFVL,was selected from ten neomycin-resistant *** showed a specific and inducible dose-and time-dependent luciferase activity in response to BFV *** the changes in luciferase activity of BFVL peaked at 84 h post infection,it was possible to differentiate infected and uninfected cells at 48 h post infection.A linear relationship was established between the multiplicity of infection (MOI) of BFV and the activated ratio of luciferase expression in ***,the sensitivity of the BFVL-based assay for detecting infectious BFV was 10,000 times higher than the conventional CPE-based assay at 48 h post *** findings suggest that the BFVL-based assay is rapid,easy,sensitive,quantitative and specific for detection of BFV infection.

笔者基于20082017年我国30家主要商业银行的面板数据,使用随机前沿分析方法(SFA)估算出银行成本效率,通过构建动态面板模型实证研究了存款市场约束对商业银行成本效率的影响。研究发现:就存款市场数量约束看,公司定期存款比重的增加对银行成本效率并无显著影响,但公司活期存款比重的上升却有利于提高银行成本效率;个人定期和活期存款占比的增加均对银行成本效率的提升产生了积极促进作用。就存款市场价格约束看,以利息支出占比为代理变量的存款市场价格约束对银行成本效率的影响异常显著,价格约束效应明显。就不同类型银行间差异看,公司类存款比重的上升对大型商业银行成本效率无明显数量约束效应,但对股份制商业银行和城市商业银行的数量约束效应相当显著;个人类存款占比的增加对股份制商业银行成本效率不存在明显数量约束效应,但对大型商业银行和城市商业银行的数量约束效应十分突出;存款市场价格约束对大型商业银行成本效率的影响不显著,但对股份制商业银行和城市商业银行却产生了显著的价格约束效应。
