Human intestinal bacteria play an important role in the metabolism of herbal medicines, leading to the variations in their pharmacological profile. The present study aimed to investigate the metabolism of Xiao-Cheng-Qi decoction(XCQD) by human intestinal bacteria and to discover active component combination(ACC) contributing to the anti-inflammatory activity of XCQD. The water extract of XCQD was anaerobically incubated with human intestinal bacteria suspensions for 48 h at 37 °C. A liquid chromatography-hybrid quadrupole time-of-flight mass spectrometry(LC-Q-TOF/MS) method was performed for identification of the metabolites. In addition, the anti-inflammatory effects of XCQD and biotransformed XCQD(XCQD-BT) were evaluated in vitro with cytokines in RAW264.7 cells induced by lipopolysaccharide(LPS). A total of 51 compounds were identified in XCQD and XCQD-BT. Among them, 20 metabolites were proven to be transformed by human intestinal bacteria. Significantly, a combination of 14 compounds was identified as ACC from XCQD-BT, which was as effective as XCQD in cell models of inflammation. In conclusion, this study provided an applicable method, based on intestinal bacterial metabolism, for identifying combinatory compounds responsible for a certain pharmacological activity of herbal medicines.

We restudy the Lee-Weinberg time-evolution equation including the R-parity violation. We carefullyanalyze the intluence of the boundary conditions, equation of state, SUSY parameters, especially the R-parity violation,and other factors on the time-evolution of the SUSY cold dark matter. Our numerical results show that without Rparity violation, only two ranges 20 ＜ mx01 ＜ 30 GeV and 75 ＜ mx01 ＜ 110 GeV can be consistent with data, if30 ＜ mx01 ＜ 75 GeV, there must be at least two kinds of heavy particles contributing to the cold dark matter. However,with the R-parity violation, the heavy neutralino can be dark matter constituent, but it must decay and the R-parityviolation parameter is constrained by the present data.

Computing the distance between two convex polygons is often a basic step to the algorithms of collision detection and path planning. Now, the lowest time complexity algorithm takes O(logm+logn) time to compute the minimum distance between two disjoint convex polygons P and Q, where n and m are the number of the polygons’ edges respectively. This paper discusses the location relations of outer Voronoi diagrams of two disjoint convex polygons P and Q, and presents a new O(logm+logn) algo- rithm to compute the minimum distance between P and Q. The algorithm is simple and easy to implement, and does not need any preprocessing and extra data structures.

本文提出了一种基于离散Sibson插值的盲反半色调方法.算法建立在统一的离散Voronoi图框架之上,通过自适应Voronoi区域估计得到种子点的灰度值,然后通过离散Sibson插值将传统的反半色调问题转化为插值问题并计算获取连续色调图像.算法不需要知道任何先验知识,因此算法具有更广的适用性,可以被应用于任意方法生成的半色调图像的反半色调处理.在效果处理方面,算法能够很好的保留原始图像的信息,同时能够更好的去除平滑区域的噪声.

小微文化企业近几年发展迅速,但数量多,效益差。笔者经过对南京的小微文化企业进行模块化抽样调研,发现其存在的问题主要集中在扶持政策过度重视经济属性而忽略了文化属性;执行政策时缺乏科学评估体系、监管体系和专业性;小微文化企业自身发展缺乏人才、资金和可持续性要素等。反观欧美大陆、澳大利亚、新加坡等国家,以及我国的台湾、香港等地区在扶持小微艺术文化发展方面已具备成熟的理念、有效的方法和完善的运作模式,值得学习和借鉴。

中国与日本的文化艺术交流具有典型的文化回流特征。从江户时代开始,中国南画在较长的历史时期中对日本都是单向输出的态势。这种输出通过来到中国的日本僧侣、旅行者、商人,也通过日本各行业来华留学者进行。中国南画单向输出到日本后,被全盘接收并逐渐本土化,形成了日本南画,成为其文化艺术基因,也形成中日文化记忆的共同基底。这种单向输出的态势到现当代发生了转变,即日本文化反向输出到中国,更明显的则是日本本土化后的中国文化艺术回流到中国,南画是其一。在这文化双向流动的过程中,艺术贸易和市场起到了重要的推动作用,并激活了两国的文化连接,找回了历史上两国人民相互学习的记忆,有效促进了两国文化命运共同体的建设。

海外英语 2016年第3期 217-219页

作者：李雪清 Shandong University of Finance and Economics

In Second Language Acquisition theory, input and interaction are considered as two key factors greatly influencing the learners' acquisition rate and quality, and therefore input and interaction research has been receiving increasing attention in recent years. Among the large amount of research, Krashen's input hypothesis and Long's interaction hypothesis are perhaps most influential theories, from which most of input and interaction studies have developed. Input hypothesis claims that comprehensible input is the only one way to acquire language, whereas interaction hypothesis argues that interaction is necessary for language acquisition. Therefore,this thesis attempts to conduct a descriptive analysis between input hypothesis and interaction hypothesis, based on their basic ideas, theoretical basis, comparisons and empirical work. It concludes that input hypothesis and interaction hypothesis succeed in interpreting the process of language acquisition to some extent, and offer both theoretical and practical inspirations on second language teaching.
