喙尾琵琶甲流浸膏的镇痛及抗炎作用研究

目的：观察喙尾琵琶甲流浸膏对小鼠的镇痛及抗炎作用。方法：用热板法和醋酸扭体法测定小鼠的痛阈值,二甲苯耳肿胀法测定抗炎作用。结果：喙尾琵琶甲流浸膏高、低剂量组均能提高扭体小鼠痛阈值,高剂量组能显著提高热板实验小鼠痛阈值;喙尾琵琶甲抗炎作用不明显。结论：喙尾琵琶甲流浸膏具有明显的镇痛作用,抗炎作用不明显。     

罗丹明类铜离子荧光探针的合成及其应用研究

设计、合成了一种基于罗丹明B的铜离子荧光分子探针RF。研究发现在V乙腈∶V水=1∶1介质中,化合物RF最大发射波长为566 nm,Cu2＋可使探针RF的荧光强度明显增大,同时溶液颜色从无色变为桃红色。该荧光探针对Cu2＋具有较高的灵敏度和较好的选择性。RF的选择性荧光增强是由于其对Cu2＋的识别开环引起的。该探针对Cu2＋的识别是不可逆的,而且pH对探针RF在中性水溶液中检测Cu2＋几乎没有影响。

三氧化钨纳米线的制备及其光催化性能

以Na2WO4·2H2O和HCl为原料,采用水热法合成了WO3,并用x射线粉末衍射（XRD）、扫描电镜（SEM）、紫外漫反射（uV—Vis）、电子能量分散谱（EDS）和激光拉曼光谱（Raman）测试手段对样品进行表征。测试结果表明,Na2SO4作为添加剂时水热合成的产物皆为六方相三氧化钨纳米线,其粗细和长短略有差异,不同浓度的Na2SO4对产品晶型和形貌无影响,但影响其晶粒尺寸,其中0．125MNa2SO4所得六方相WO3纳米线的尺寸最小,平均直径约为5nm,长度约为1um,并具有最佳的光催化活性,可见光（≥420nm）照射150min罗丹明B溶液后的降解率达96．01％。     

椭圆曲线的Bézier多项式逼近

椭圆曲线是计算机辅助几何设计中基本且重要的曲线.本文首先利用Tchebyshev多项式去逼近椭圆,再在此基础上得到插值椭圆首、末端点的n次Bézier多项式逼近.该算法可以逼近整椭圆,而且适合圆的逼近.

基于局域核心择优模型的B2B电商网络仿真研究

通过运用复杂网络对B2B电商网络进行建模仿真,发现B2B网络的运行规律,提出减少平台风险的措施。首先分析B2B电商网络的特征和演化动因,提出网络演化的动态规则、局域择优连接规则和自演化规则。接着基于演化规则,在BA模型的基础上,构建更契合于B2B电商网络的局域世界核心择优连接(Local world Core Preferred connection)演化模型。最后,采用NetLogo软件对LCP演化模型进行仿真实验。结果验证B2B电商网络具有无标度性,发现网络具有小世界性;以及网络对随机干扰具有较强的鲁棒性。     

Ferulic acid prevents liver injury and increases the anti-tumor effect of diosbulbin B in vivo

The present study is designed to investigate the protection by ferulic acid against the hepatotoxicity induced by diosbulbin B and its possible mechanism, and further observe whether ferulic acid augments diosbulbin B-induced anti-tumor activity. The results show that ferulic acid decreases diosbulbin B-increased serum alanine transaminase/aspartate transaminase (ALT/AST) levels. Ferulic acid also decreases lipid peroxide (LPO) levels which are elevated in diosbulbin B-treated mice. Histological evaluation of the liver demonstrates hydropic degeneration in diosbulbin B-treated mice, while ferulic acid reverses this injury. Moreover, the activities of copper- and zinc-containing superoxide dismutase (CuZn-SOD) and catalase (CAT) are decreased in the livers of diosbulbin B-treated mice, while ferulic acid reverses these decreases. Further results demonstrate that the mRNA expressions of CuZn-SOD and CAT in diosbulbin B-treated mouse liver are significantly decreased, while ferulic acid prevents this decrease. In addition, ferulic acid also augments diosbulbin B-induced tumor growth inhibition compared with diosbulbin B alone. Taken together, the present study shows that ferulic acid prevents diosbulbin B-induced liver injury via ameliorating diosbulbin B-induced liver oxidative stress injury and augments diosbulbin B-induced anti-tumor activity.     

The Development of Business-to-Business Magazines in China

Business-to-Business (B2B) publications actually have a long history in China, beginning in the early twentieth century. After 1949, the Chinese economy became planned and regulated by the government, the former B2B magazines became their purpose to explain the government’s industrial policies, chart business direction and exchange developmental experience. As China began its reform and opened to a market economy in the 1980s, traditional published B2B magazines began to reappear. Today almost 3,000 B2B magazines provide information about specific industries and services.
