英文摘要:The mortality rate of hepatocellular carcinoma is ranked Top one in Fujian province and has received increasing attention. In recent years, immunotherapy has gained renewed interest as an alternative therapeutic approach for hepatocellular carcinoma. Its premise is based on harnessing the power of the host immune system to destroy cancer cells. Development of immune-mediated therapies, such as nanovaccines, and stimulation of host immunity by targeting tumor-evasive mechanisms have advanced hepatocellular carcinoma immunotherapy. Preclinical and clinical studies with immune-mediated therapies have shown potential benefits in patients with hepatocellular carcinoma. Recently, cell plasma membrane derived vesicles (CMVs) have attracted lots of attention for their potential roles as drug carriers for immune-mediated therapies. As naturally derived materials, CMVs are completely biocompatible which makes them the idea nanoplatform forimmunotherapy purposes. Here we aim to develop a nanoplatform technology that can solve the challenges in the fabrication and engineering of CMVs for hepatocellular carcinoma immunotherapy. Specifically, we will fabricate CMVs by self-assembly of purified cell membrane extract, mainly lipid rafts separated from other cellular components using the density gradient. A proof-of-concept study will be performed with antigen peptide and imaging probe co-delivery with CMVs extracted from engineered cells. In addition, studies on mechanisms of immune evasion and using molecular imaging have enhanced our understanding on the immunology of hepatocellular carcinoma. Development of molecular imaging technology for high sensitivity, high-resolution multi-modality imaging will open up a broader application in early response for hepatocellular carcinoma immunotherapy. We design and prepare a series of novel targeted theranostic CMVs by using unique natural biological of CMVs, genetic expression of antigen peptides on its surface and self-assembly methods to load imaging probes, to achieve multi-modality imaging-guided hepatocellular carcinoma immunotherapy. We seek to determine and delineate the sophisticated multifunctional theranostic agents with optimized properties for arrange of related applications: efficient nanovaccine delivery, non-invasive quantitative analysis on the distribution of CMVs and early immunotherapy response in vivo. If successful, the proof-of-concept will allow for preclinical and clinical applications of CMVs in hepatocellular carcinoma immunotherapy.二题目:智能诊疗剂的制备及在PET/MRI/PA三模态成像和靶向热疗中应用研究项目类别:面上项目申请代码:E0310批准年度:2015年中文摘要:肿瘤的诊断与治疗分离是肿瘤临床主要问题之一,智能诊疗剂有望解决这个问题。
论文中英文摘要
论文中英文摘要作者姓名:陈建业论文题目:壳内软弱层特征:实验研究及数值模拟作者简介:陈建业,男,1983年9月出生,2006年09月师从于中国地震局地质研究所杨晓松研究员,于2009年7月获硕士学位。
中文摘要壳内软弱层对于理解中国大陆现今岩石圈结构、板内造山动力学以及强震孕育背景具有十分重要的意义。
本文针对壳内软弱层的岩石物理性质、动力学特征进行了高温高压试验、相似材料实验以及数值模拟研究,得到如下认识:对来自青藏高原聂拉木群高喜马拉雅结晶岩系的二云母片麻岩进行了一系列高温高压条件下波速测量。
结果显示在低温段(<600ºC),样品波速随着温度和压力的变化呈现为很好的线性关系。
在高温段,波速随着温度和压力的关系呈现为明显的非线性。
对白云母脱水(熔融)和α石英高温软化导致波速的非线性快速下降有了新的认识,该结果对于认识高地温梯度地区和加厚酸性地壳地区,中上地壳速度结构的反转有指示作用。
由白云母脱水和石英高温软化形成的低速层与α-β相变导致波速的快速上升形成鲜明的对比,为高热流地区类似波速探测结果的理解提供重要的价值。
另外,波速-深度在不同地温梯度下的测量给出了地壳内出现“波速反转”以及α-β相变附近波速快速上升的直接结果,为地球物理探测结果的解释提供直接证据。
青藏高原深部地壳具有很强的地壳各向异性,造岩矿物的LPO不足以解释青藏高原地壳中所观测到的各向异性强度。
模拟计算表明低度熔体的定向分布能够显著地强化岩石的各向异性,并且MPO引起的各向异性强度可以比由LPO导致的各向异性强度大数倍。
因此,如果地壳中存在部分熔融机制,则定向分布的熔体对各向异性的贡献应该被充分地考虑。
相似性材料的实验结果表明,定向分布的熔体可以显著的强化介质的各向异性。
在低度熔融的条件下熔体诱发的各向异性强度可以到达原固态介质各向异性强度的1~2倍。
众多研究资料显示,青藏高原-川滇西部地壳中区域性分布的低速层与低度部分熔融关联。

Abstract
Section Willkommia (Centaurea, Compositae) is endemic to the east-central portion of the Iberian Peninsula and northwestern Africa.The section has been included with sections Acrolophus and Phalolepis in the informal subgroup Acrolophus. We have used a molecular phylogenetic approach to test the hypothesis proposed by earlier authors that the diversiWcation of section Willkommia involved a schizoendemic process from an ancestral syngameon. Comparative analysis of the transcribed spacer sequences of the nuclear ribosomal DNA (ITS and 3‘ETS) regions reveals the presence of three diVerent types of ribosomal sequences in the Acrolophus subgroup (referred to here as the Willkommia, Acrolophus–Phalolepis and Simulans ribotypes) which show a sectional-independent geographic structure. This evidence, together with the presence of additive polymorphic sites in the Willkommia sequences which agree with the geographic distribution of the taxa, suggests that members of section Willkommia and the western Mediterranean taxa of sections Acrolophus and Phalolepis Wt a reticulate evolution model.

国自然英语文献格式Title: The Nature of China: English Literature FormatIntroductionIn recent years, the concept of “国自然” or “the nature of China” has been gaining popularity among environmentalists, scholars, and policymakers alike. This concept refers to the unique natural landscapes, ecosystems, and biodiversity that can be found across China. In this paper, we will explore the various aspects of “国自然” and discuss how it is represented in English language literature.The Diversity of China’s NatureChina is home to a diverse range of natural landscapes, from the towering peaks of the Himalayas to the lush forests of Yunnan province. The country’s vast size and varied topography have given rise to a wide array of ecosystems, each with its own unique flora and fauna. From the Siberian tiger in the northeast to the giant panda in the southwest, China is teeming with biodiversity.The Cultural Significance of China’s NatureIn Chinese culture, nature has always held a special place. The country’s rich tradition of poetry, painting, and philosophy is replete with references to the natural world. From the Daoist concept of harmony with nature to the Confucian emphasis on the transformative power of the natural world, China’s cultural heritage is deeply intertwined with its natural environment.Representations of “国自然” in English LiteratureIn recent years, a number of English language authors have begun to explore the concept of “国自然” in their work. Barbara Demick’s book “Besieged by Nature” offers a vivid portrait of the impact of China’s rapid economic development on its natural environment. Through a series of interviews and firsthand observations, Demick paints a stark picture of the challenges facing China’s fragile ecosystems.Another notable work is Peter Matthiessen’s “The Snow Leopard,” which chronicles the author’s journey through the Himalayas in search of the elusive snow leopard. Through lyrical prose and vivid descriptions, Matthiessen captures the beauty and majesty of China’s mountainous regions, as well as the threats they face from climate change and habitat destruction.ConclusionIn conclusion, the concept of “国自然” is a rich and multifaceted one that holds immense significance for China and the world at large. By exploring this concept through the lens of English language literature, we gain a deeper understanding of the complex relationship between humans and the natural world. As China continues to grapple with the challenges of environmental degradation and climate change, it is more important than ever to preserve and protect the unique ecosystems that make up the “nature of China.”References:1.

如下所示:α-取代甲苯定向硝化的理论研究摘要运用密度泛函理论(DFT), 研究了吸电子氟基和供电子羟基在取代甲苯的α-H 以后, 其邻、间、对各位次进行硝化反应的速控步骤, 在B3LYP/6-311G**水平上, 计算了该速控步骤基元反应各反应驻点(反应物、过渡态和中间体)的优化几何、电子结构和能量性质, 并首次给出了目标硝化反应速控步骤的IR 谱学的动态特征及解析, 从微观层面上验证了反应坐标C—N的形成和C—H的断裂是非协同的, 从而无一级动力学同位素效应的实验事实. 通过对目标硝化反应速控步骤的微观动态计算, 验证了氟基对甲基定位的影响. 氟基的电负性大, 吸电子能力强, 取代甲苯的α-H 以后对硝酰阳离子的进攻有抑制作用, 活化能较取代前高, 但比较苄基氟各位次硝化活化能的相对大小得知, -CH2F 仍为邻、对位定向基团. 而供电子羟基取代甲苯的α-H 以后, 则对硝酰阳离子的进攻有促进作用, 因而各反应驻点络合物的稳定化能较α-H 取代前甲苯的有所增大, 且邻、对位硝化的活化能较间位低, 故-CH2OH 为邻、对位定位基. 但对位因硝化活化能低, 反应放热多, 空间位阻小, 为亲电试剂NO+最有利的进攻位;而邻位则因羟基取代甲苯α-H 后多了2一个氧原子, 增大了邻位进攻的空间位阻, 使得其络合物的能量比相应对位的高.关键词:苄基氟,苄醇,α-取代,取代基效应,速控步骤Theoretical Study on Selectivity for Nitration of α-Substituted Toluene with NitroniumAbstractThe rate-determining steps of isomeric ortho, meta and para nitrations of benzyl alcohol and benzyl fluoride have been theoretically investigated at B3LYP/6-311G** level. Stationary points of the step involving reactant, transition state and intermediate complexes were successfully located and characterized without any restriction on the internal coordinates. Their molecular geometries, electronic structures, IR spectra, and the FMO symmetries of two initial aromatic compounds and the nitronium ionNO+have2been studied. The vibrational shifts of C—N and C—H stretches from TS to INT at the rate-determining step of target aromatic nitrations show up that the formation of C—N and the cleavage of C—H are not con-cerned but stepwise to provide an explanation, on a microscopic scale, for the experimental fact of the absence of kinetic isotopic effect in the nitration process for the first time. Also, the influence of introduced fluorine on the orientation effect was figured by calculating the microscopic and kinetic properties of the rate-determining step of concerned aromatic nitrations. TheNO+attack to the benzyl2fluoride was deactivated because of high electronegativity and strong electron withdrawal of fluorine atom. The activation energy af ter α-substitution of methyl group by a fluorine atom became higher. Yet the CH2F group was still an ortho-para directive, since the activation energies of ortho and para nitrations were relatively lower than that of meta nitration. Contrarily, the introduction of electron-donating substituent OH onto the methyl accelerated theNO+attack. Consequently the stabilization energies of complexes were droped even 2lower than before the α-substitution occurred. The activation energies of ortho and para nitrations, however, were also quite lower than the energy of meta nitration. Therefore, the CH2OH is an ortho-para directing group. Compared to the ortho, the para position is the most favorable due to theNO+to approach, for its low steric hindrance effect and high2exothermicity. Attack at ortho, however, became even more crowd since one more O atom has been introduced after the α-substitution onto the methyl group. Hence, the energy of ortho nitrobenzyl alcohol complex is higher than the energy of para one.Key words:benzyl fluoride; benzyl alcohol,α-substitution,substituent effect,rate-determining step。
