The regulation of gene expression is to have relations to the assembly of the DNA binding proteins which bind to DNA to initiate the transcription. Some of these proteins have the ability to promote bending or looping of DNA. The FIS protein regulates gene expression in Escherichia coli by this property of bending DNA. There are many researches to discover the mechanism of FIS protein binds to DNA. However the experiment data only show the supposititious results and figure out the model of FIS-DNA complex structure. This research uses molecular dynamics simulation to compute the detail of the interaction between FIS and DNA. We observed FIS prominently affects the DNA bending by the type of local bending. Analyzing the DNA structure properties, roll and slide, also demonstrates the local bending type and region. The hydrogen bonds between FIS and DNA are analyzed to compare with the experiment data. Finally we compute the binding free energy between FIS and DNA to estimate the result of simulation and compare with the value of λ-repressor-DNA complex.
基因的表现与结合於DNA促使DNA转录作用起始的DNA结合蛋白组装有关,一些这类的蛋白质具有促使DNA扭曲或将DNA形成环状的能力,FIS蛋白质即是藉由扭曲DNA的特性调控大肠杆菌基因的表现,目前已有很多的研究发现FIS与DNA结合的机转,然而这些实验的数据仅能显示推测性的结果,进而利用这些结果推论出FIS与DNA聚合体结构的模型,本研究利用分子动态模拟的方式计算FIS与DNA交互作用的细节,我们观察到FIS主要影响DNA的扭曲方式为DNA区域扭曲的类型,并且分析DNA结构特性roll与slide也指出扭曲方式为区域扭曲与其扭曲的区域,我们也分析FIS与DNA之间的氢键,并且与实验的资料作比较,最后我们计算FIS与DNA之间的结合自由能评估模拟的结果,并且计算出的值和λ-repressor与DNA聚合体结构的实验值作比较。

Results are as followed:1 Exposure of HELF cells to BP caused c-Jun activation,and increased the activity of MAPK,PI-3K,p53 and cyclin D1 pathway.2 BP-induced c-Jun activation was inhibited by dominant negative mutants of extracellular signal-regulated protein kinase or c-Jun NH_2-terminal kinase,but not by p38,impling that JNK and ERK pathways medicate c-Jun activation induced by BP.3 Overexpression of dominant-negative mutants PI-3K and Akt potently blocked phosphorylations of c-Jun and ERK,but not JNK in response to BP,suggesting that PI-3K/Akt pathway positively regulates BP-induced c-Jun activation through ERK.4 Inhibition of p53 by its chemical or molecular inhibitor markedly increased the phosphorylation levels of c-Jun,Akt and ERK upon BP stimulation,indicating that p53 negatively medicates BP-induced c-Jun activation through PI-3K/Akt/ERK pathway.5 The cell lines expressed TAM67 exhibits no significant affecting normal cell growth properties.6 TAM67 was able to significantly block G_1-S transition and subsequent cell proliferation,suggesting that c-Jun is essential for cell cycle alternations elicited by BP.7 Overexpression of TAM67 impaired BP-induced cyclin D1 activation,decreasing expression of E2F1 and pRb,indicating that c-Jun participates in the modulation of BP-induced activation of cyclin D1/pRb/E2F1 pathway.8 Stably expression of TAM67 led to the increases in the expression levels of p53 and p21,elevating phosphorylation level of p53,clearly indicating that c-Jun regulates p53/p21 pathway activation induced by BRCollectively,PI3K/Akt/ERK pathway mediated BP-induced c-Jun activation through p53-dependent mechanism.
结果显示:1BP刺激细胞可促进c-Jun活化,并伴随着MAPK、PI-3K、p53和cyclinD1通路各组成成分的活性增强。2利用MAPK通路的显性失活突变体分别阻断细胞外信号调节激酶和c-Jun氨基末端激酶活性,均可明显抑制BP诱导的c-Jun活化,但阻断p38活性对BP引起的c-Jun活化无明显影响,提示JNK和ERK通路参与调控BP诱导的c-Jun活化。3过表达PI-3K和Akt的显性失活突变体也可显著抑制BP诱导的c-Jun活化,并降低磷酸化ERK的表达水平,但对磷酸化JNK的表达水平无明显影响,说明PI-3K/Akt通路通过ERK正性调控了BP诱导的c-Jun活化。4p53的化学/分子抑制剂能使BP作用的细胞内c-Jun活性明显增加,并同时诱导Akt和ERK的磷酸化水平的升高,表明p53可通过PI-3K/Akt/ERK通路对BP诱导的c-Jun活化进行负性调控。5随后观察转染细胞的生长情况,发现TAM67对细胞正常生长和形态无明显影响。6稳定表达TAM67可有效抑制BP诱导的S期细胞数的增加,提示c-Jun在BP致细胞周期改变的过程中发挥了重要作用。7TAM67过表达能够抑制BP诱导的cyclin D1活化,降低磷酸化Rb以及E2F1蛋白表达水平,表明c-Jun参与调控BP诱导的cyclin D1/Rb/E2F1通路的活化。8过表达TAM67可使BP刺激的细胞中p53、p21总蛋白以及p53磷酸化的表达水平明显升高,可见c-Jun也参与调控BP诱导的p53/p21通路活化。

The main points of the articles are as follows: 1. In methodology, there should be two paths for study of justice corruption----the therectical and demonstrative ways. 2. Confrontation of interests is the inner drive of interation between the players of justice corruption game. This drive pushes the orderly changes of justice corruption.

A new study idea that makes the occupant injury prevention research and CAD/CAE technology on an integrate mathematical model by means of feature theories and feature design technologies was brought, and it is maybe useful if we study automobile passive safety on a new view of point.The conclusions of this thesis included that what are the main factors of airbag-related injuries and the preventive measures, based on the research of the relationships between injury parameters, such as HIC, chest acceleration, neck force, neck moment, femur axial force etc, and impact speed, belt-use, occupant size (50th and 5th), sitting position and so on. The thesis evaluated whether the effectiveness of the airbag can be increased by making the airbag adaptive to the crash conditions, and points out that the size of the ventilation hole has the dominating influence on the performance of the airbag and is a key factor for intelligent airbag, multi-stage and lower-power inflator can cost effectively minimize the risk of injury to occupants from crashes. It is important for the researchers of intelligent airbag to keep the small size unbelted occupants in focus and it is necessary to study deeply the influence of airbag fold patterns and the extremity out-of-position situation. These topics are important in the study of occupant injury prevention and vehicle safety design.

It is concluded in Chapter Eight that: 1 linguistic proficiencies in three languages play a considerable part in code-switching of EFL teachers in trilingual context; the inter-sentential switching outweighs the intra-sentential switching both in frequencies and percentage; discourse-related switching also outweighs participant-related switching in frequencies and percentage; the EFL is maintained longest in EFL classroom and the language maintained second longest depends upon learners" higher proficiency in Chinese or Tibetan. 2 Ethnic identity and educational background is the major causal factor of EFL teachers" Chinese-English switching in trilingual classroom; duration of language contact and relative trilingual proficiencies are the two principal contributors to the English-Tibetan switching; while Tibetan-English switching is mainly driven by EFL teachers" ethnic identity and education background, as well as the duration of language contact; English-Chinese switching is also largely motivated by the duration of trilingual contact; and Chinese-Tibetan switching is determined by trilingual proficiency to a considerable extent. Meanwhile, psychologically, the switching is mainly motivated by a procedure of psychological projection, trilingual system conceptualization and the mentality of trilingual selection. 3 The educational reflections upon this study indicate: firstly, in trilingual context, the teachers" classroom discourse is characterized by the multilingual involvement, flexibility in strategy option as well as the extension and strengthening of the domination of teachers" discourse. Secondly, the discourse movement and code-switching are largely affected by two cultural ecological mechanisms: enculturation and cultural manipulation. Thirdly, the status quo of EFL trilingual teachers are characterized by unbalanced trilingual proficiencies, poor cultural awareness, and little knowledge of trilingual education and trilingual code-switching, therefore, suggestions are advanced in the end to provide them further education. Fourthly, in trilingual context, the EFL curriculum for ethnic minorities is characterized by plurality of aims, complexity of organization and variety of resources. Meanwhile, it is of great necessity to understand the linguistic values of EFL education for ethnic minority learners. To be specific, firstly, we should not only have a deep understanding of the distribution, construction, function as well as communicative effects of the three languages, but also have a comparative study of the three languages and thus provide the standardization and guidance for the trilingual education. In the end, it is advanced that trilingual EFL provision for ethnic minority should pursue to develop learners" multicultural value system in which first language culture and mother language culture take the central position and EFL culture plays a vital role.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
