Nighty rats were randomly divided into the groups of control, myocardial infarction and doxycycline, which were given orally 48 hours before and 48 hours after MI with 30mg/Kg per day. Protein and mRNA extraction was done on left ventricular samples containing scar and myocardium together. Samples were assayed from 1 day to 4 weeks post-Mi. The activity of MMPs was measured by zymography and collagen amount by the method of chloramine T, the ratio of II III collagen was assessed by immunohistochemical stain. Protein and mRNA of MMP-2, 9, TIMP-1 were determined by Western-Blot and RT-PCR.

The contrastive research is fully conducted from Chapter Four to Chapter Six. Chapter Four studies negation in English and in Chinese at the lexical level, which can be further divided into three sublevels, namely, morpheme, word, and phrase. Chapter Five studies negative sentences, explicit negative form at the syntacticlevel. And the study covers the classification, syntactic feature, nonassertive/assertive items, scope/focus of negation, two important tendencies, and some common special negative sentences. Chapter Six focuses on the implied negative sentences in English. According 10 devices employed to achieve negation, implied negative sentences are divided into four categories, namely, implied negative sentences by grammatical devices, by semantic devices, by rhetorical devices, and by pragmatic devices.

从第四章到第六章具体地展开了英汉否定对比研究：第四章的研究在词汇平面上进行，分为语素、词语和词组：第五章对比研究了在句子平面上英汉否定中的显式现象—否定句，主要涉及否定句句法特征和分类、句型转换、否定范围和否定焦点、全句否定和局部否定、转移否定、双重否定、部分否定和全部否定、强调否定和否定问句回答等方面；第六章集中研究了英语含蓄否定句，按照一个含蓄否定句采用何种手段实现意义上的否定进行一下分类，把含蓄否定句分为四类—通过语法手段实现的含蓄否定句，通过语义手段实现的含蓄否定句，通过修辞手段实现的含蓄否定句，通过语用手段实现的含蓄否定句。

Methods Peritoneal macrophages of guinea pigs were infected in vitro by three different Leptospira strains, the virulent Leptospira interrogans serovar Lai type strain Lai, the avirulent L. interrogans serovar Lai type strain IPAV, and the nonpathogenic L. biflexa serovar Patoc type strain PatocⅠ, respectively, and heat inactivated Staphylococcus epidermidis was added 0.5, 1.5, 3 and 6 h after infection and incubated for 30 min. The effect of Leptospira on the phagocytosis of macrophage was evaluated by the inactivated Staphylococcus epidermidis phagocytosis rate and phagocytosis index. Phagocytosis and ultrastructure of peritoneal macrophages were observed by transmission electron microscopy 3 h after infection, and changes of cytoskeleton of the macrophages were observed by laser scanning confocal microscopy.

应用脉冲之间的非简并双光子吸收过程，探索出了对受自由载流子吸收作用而形成的自压缩脉冲进行压缩整形的新方案，通过调节脉冲之间的初始时延和控制脉冲的能量，可以优化自压缩脉冲的质量；另外，应用此效应，也实现了超快脉冲对连续光场的全光调制和超快逻辑非门的操作，在光调制过程中，发现了色散和初始啁啾都将改变所形成的调制暗脉冲的调制深度。

First, the proposed scheme uses contourlet transform to extract multidirectional and multiscale texture information, and then obtains the feature points invariant to the affine transformation from the low and middle directional subbands by Harris-Affine detector. Second, the feature regions are adaptively computed by the feature scale of the local structure and normalized by U transform. The watermarking is embedded adaptively in those characteristic regions which are normalized. Finally, by vector quantization, several copies of the watermark are embedded into the no overlapped local feature regions in different directional subbands.

首先，用Contourlet变换提取出多尺度、多方向的纹理信息；再用Harris-Affine检测算子从变换域的中、低频方向子带中提取出仿射不变特征点，结合自适应局部结构的特征尺度确定特征区域，并用U变换对其归一化处理，水印就自适应地嵌入到归一化后的区域中；水印嵌入采纳矢量量化的策略，将水印信息重复嵌入到不同方向子带、多个不相交的局部仿射不变特征区域。
