Carbosilane dendrimers with p-bromophenyl core were synthesized by alternating Grignard and hydrosilylation reaction. And the α-naphthalenyl was connected to the core by the Suzuki coupling reaction. A new carbosilane dendrimer with big π-conjugated structure [4-（naphthalen-l-yl）phenyl core] was given. It shows Suzuki coupling reaction is an effective and powerful core-functionalization method and the satisfactory result can be obtained through prolonging the reaction time with the increase of the generation of dendrimer.

Based on complex variables and conformal mapping, the elastic wave scat- tering and dynamic stress concentrations in the plates with two holes are studied by the refined dynamic equation of plate bending. The problem to be solved is changed to a set of infinite algebraic equations by an orthogonM function expansion method. As examples, under free boundary conditions, the numerical results of the dynamic moment concen- tration factors in the plates with two circular holes are computed. The results indicate that the parameters such as the incident wave number, the thickness of plates, and the spacing between holes have great effects on the dynamic stress distributions. The results are accurate because the refined equation is derived without any engineering hypothese.

BACKGROUND In recent years, the incidence of types Ⅱ and Ⅲ adenocarcinoma of the esophagogastric junction(AEG) has shown an obvious upward trend worldwide. The prognostic prediction after radical resection of AEG has not been well *** To establish a prognostic model for AEG(types II and III) based on routine *** A total of 355 patients who underwent curative AEG at The First Affiliated Hospital of Anhui Medical University from January 2014 to June 2015 were retrospectively included in this study. Univariate and multivariate analyses were performed to identify the independent risk factors. A nomogram was constructed based on Cox proportional hazards models. The new score models was analyzed by C index and calibration curves. The receiver operating characteristic(ROC) curve was used to compare the predictive accuracy of the scoring system and tumor-node-metastasis(TNM) stage. Overall survival was calculated using the Kaplan-Meier curve amongst different risk AEG *** Multivariate analysis showed that TNM stage(hazard ratio [HR] = 2.286, P = 0.008), neutrophil-tolymphocyte ratio(HR = 2.979, P = 0.001), and body mass index(HR = 0.626, P = 0.026) were independent prognostic factors. The new scoring system had a higher concordance index(0.697),and the calibration curves of the nomogram were reliable. The area under the ROC curve of the new score model(3-year: 0.725, 95% confidence interval [CI]: 0.676-0.777;5-year: 0.758, 95%CI:0.708-0.807) was larger than that of TNM staging(3-year: 0.630, 95%CI: 0.585-0.684;5-year: 0.665,95%CI: 0.616-0.715).CONCLUSION Based on the serum markers and other clinical indicators, we have developed a precise model to predict the prognosis of patients with AEG(types II and III). The new prognostic nomogram could effectively enhance the predictive value of the TNM staging system. This scoring system can be advantageous and helpful for surgeons and patients.

从20世纪90年代起,博耶提出了教学学术的理论,舒尔曼等人拓展了这一理论并强调教学学术的可视化、技术化,从而在高等教育领域掀起了一场方兴未艾的教学学术运动。教学学术本质上是行动研究,以高校专业教师为研究主体,在教学实践过程中进行,以改进教学为根本出发点和归宿;实践性是其本质特征。教学学术具有多样化的成果形式,但任何成果归根结底都必须体现于教学效果。“唯论文”是教学学术的一大误区,教学学术评价中“唯论文”的危害远甚于科研评价的“唯论文”。

高校教学以高深知识为内容,以学生的发展为宗旨。高等教育“教学成果”理应是目标与结果的统一、师生双边主体作用的统一、短期效果与长期效果的统一、主观与客观的统一,归根结底应是教学与发展的统一,它只能由学生的发展来认定。由于高校教学目标具有模糊性和动态性,教学效果的载体形式异常复杂,评价主体的地位明显不对称,因此高等教育“教学成果”实际上处于“测不准”的状态,高等教育“教学成果奖”在实施过程中也就出现各种歧义。若高等教育“教学成果奖”所奖非所实,就可能助长虚饰浮夸之风,造成教学质量假象,并使“良心活”发生异化。为此,亟须对高等教育“教学成果”进行前提性反思和正当性审查。

院校研究是高等院校对本校实际问题的咨询性研究。从20世纪中叶开始,院校研究首先在美国体制化,成为高校的一种治理要素和专门职业,随后传播到其他很多国家,如今已成为一个世界性现象。中国的院校研究在21世纪初起步,目前仍处于初级阶段,主要瓶颈是高校对它的有效需求不足。中国院校研究的未来发展,取决于高等教育管理体制改革的深化与院校研究者自身的专业发展。

中国高等教育学于1983年进入《学科目录》,这是由天时地利、特殊的学科体制、特殊的人物共同催生的结果。高等教育学在建制上“早产”,具有双重效应:一方面,研究者很早就有了学科归属,可以在大的学科参照系上通过实践反思和研究生培养而加速学科的发展;另一方面,孕育不够充分,先天有所不足。1983年进入建制之后,高等教育学被研究对象超常规发展的节奏所裹挟,又出现了某种后天失调。高等教育学界关于“学科”与“研究领域”之争,源于参照系的不同。高等教育学虽然现在还不是一门“成熟学科”,但它事实上已经是一个“知识的门类”“学术的门类”及“教学的科目”,因而是一门自成体系的学科。为了促进这门学科逐步走向成熟,当务之急是坚持高等教育学的学术取向,更加注重它的学术使命、问题意识、研究方法和表达方式以及学术的立场和精神。

Quorum sensing（QS） is a type of microbe-microbe communication system that is widespread among the microbial world, particularly among microorganisms that are symbiotic with plants and animals. Thereby, the cell-cell signalling is likely to occur in an anaerobic rumen environment, which is a complex microbial ecosystem. In this study, using six ruminally fistulated Liuyang black goats as experimental animals, we aimed to detect the activity of quorum sensing autoinducers（AI） both in vivo and in vitro and to clone the lux S gene that encoded autoinducer-2（AI-2） synthase of microbial samples that were collected from the rumen of goats. Neutral detergent fiber（NDF） and soluble starch were the two types of substrates that were used for in vitro fermentation. The fermented fluid samples were collected at 0, 2, 4, 6, 8, 12, 24, 36, and 48 h of incubation. The acyl-homoserine lactones（AHLs） activity was determined using gas chromatography-mass spectrometer（GC-MS） analysis. However, none of the rumen fluid extracts that were collected from the goat rumen showed the same or similar fragmentation pattern to AHLs standards. Meanwhile, the AI-2 activity, assayed using a Vibrio harveyi BB170 bioassay, was negative in all samples that were collected from the goat rumen and from in vitro fermentation fluids. Our results indicated that the activities of AHLs and AI-2 were not detected in the ruminal contents from six goats and in ruminal fluids obtained from in vitro fermentation at different sampling time-points. However, the homologues of lux S in Prevotella ruminicola were cloned from in vivo and in vitro ruminal fluids. We concluded that AHLs and AI-2 could not be detected in in vivo and in vitro ruminal fluids of goats using the current detection techniques under current dietary conditions. However, the microbes that inhabited the goat rumen had the potential ability to secrete AI-2 signaling molecules and to communicate with each other via AI-2-mediated QS because of the prese
