One hand mechanical obstruct led to the increase of veinous resistance and the obstacle of microcirculation, the other hand the adhesive PMN was activated in excess, the white blood cells released a lot of enzymes, in which PMN-elastase can decompose the components of cell and many albumens, inclusive of immunoglobulin、alexin and fibrication. These components induced the injury of the pancreatic capillary vessels and cell and lysosome enzy made the tissue protein hydrolyze and produced unsaturated fatty acids, which destroyed the structure and function of cellar membrane. The inflammatory cellar factors activate other immunocytes to produce the injury and necrosis of tissue, which aggravated the pathological injury and led to shock、pyaemia and MODS. So ICAM-1 and LFA-1 played an important role in SAP. Frossard found that the expression of ICAM-1 in the rat model, especially in serum、pancreas and lung. All these showed ICAM-1 is an important factor in AP and concomitant lung injury.

To better understand the roles of LsrA protein in nodulation, a series of analyses of nodules using scanning electron microscopy, genetic and biochemical approaches have been carried out. Our analyses suggest that the lsrA1 nodules contain bacteroids in the invasion and establishing zone only. The lsrA gene expression is active early in the invasion zone and activated later than bacA genes. The lost of LsrA protein dramatically reduced the expression of nifA and fixK, and completely blocked the expression of the nifH gene for nitrogenase. LsrA protein functions early in the bacteroid development and it is essential for the development nitrogen fixing bacteroids.
前期的工作中,苜蓿中华根瘤菌Rm1021中90个候选LysR基因已经被定向插入突变,并筛选在自生生长时期、共生生长时期的表型,以期寻找更多在自生状态或共生固氮中有功能的LysR转录因子。1 针对前期鉴定出的共生固氮必需的lsrA基因,我们应用了一系列扫描电子显微镜技术、生物化学、分子遗传学等方法,发现lsrA基因主要在根瘤侵染区开始表达,表达时序也在侵染阶段左右,但晚于bacA基因表达;LsrA蛋白缺失后根瘤固氮区中缺乏具有固氮能力的类菌体,nifA和fixK基因的转录水平降低,nifH基因的转录被完全阻断,因此LsrA蛋白为根瘤发育所必需,是新的根瘤发育信号传导途径成员。2 通过表型筛选我们鉴定了苜蓿中华根瘤菌的oxyR基因,并研究了它的调节特性。oxyR突变后,苜蓿中华根瘤菌对过氧化氢敏感性提高,适应性降低。

结果:(1)在无血清条件下单独培养的DRG,背根神经节的轴突数目众多,外形纤细弯曲,不成束,并且施万细胞和成纤维细胞稀少,所以可以排除两者对轴突生长的影响,为观察来源于变性坐骨神经段的可溶性因子对轴突生长的作用提供了有利条件;(2)在无血清条件下DRG和变性坐骨神经段联合培养,①先单独培养DRG,4天后待神经元轴突长出,再与坐骨神经段联合培养,观察到神经元的轴突数目减少,外形挺直,部分轴突之间相互粘附成束;②变性坐骨神经段和DRG同时联合培养,神经元的轴突数目明显减少,外形粗壮,轴突之间相互粘附成束;(3)有血清条件下单独培养DRG,轴突数目较多,外形挺直,长短不一,部分神经元的轴突之间相互粘附,施万细胞和成纤维细胞数目众多,观察到的轴突生长情况受到施万细胞和成纤维细胞的直接或者间接的影响。

Firstly, several kinds of schemes were proposed according to the design demand. The best scheme was chosen after analyzing and comparing the schemes. The robot's structure was designed with Pro/Engineer and AutoCAD software. Secondly, the kinematics analysis conducted, coordinate transformation matrix using D-H method was set up, and the kinematics equation direct solution and inverse solution was deduced. The manipulative interface about the kinematics equation direct solution and inverse solution was completed with VC++ and the velocity Jacobian of displacement matrix was constructed using differential transform method. In the process of the trajectory planning based on robot's kinematics analysis, I propone a method by which we can get middle nodal point with normalizing factor in order to simplify our searching for these middle nodal points. In addition, I give these middle nodal points with actual physics signification. For eliminating contradiction between real-time and accuracy, I bring forward separately limit of error and reversal interpolation method. For decreasing calculation quantity, we resort to tri-spline interpolation in the articulation space.We analyse the work range of the robot by resorting to graphic means.

The project implemented a systemic investigation to the pupa period of wild silkworm comparatively, which from Shanxi, Jiangsu, Sichuan, Chongqing, Guizhou provinces and so on. According to the investigation, the pupa dormant characteristic of Shaanxi wild silkworm was found, and the individual, which pupa period was more than two months was selected. Through the hybrid genetic analysis we found that the characteristics for a long period of pupa was controlled by polygene and genetic recessively and strongly influenced by environmental conditions at the same time. To compare the performance of pupa period of the pupa dormant wild mulberry silkworm, we designed different ecological conditions. The result indicating that the temperature is the main factor in the ecological impact, but the pupa period was extended at the same temperature conditions, indicating that the additive effects of the environmental factors.

To test this concept in transplant recipients, we evaluated complement, complement regulator, and T cell/proinflammatory marker gene expression by quantitative real-time polymerase chain reaction in 71 archived heart transplant biopsies and correlated the results with the histologic grade of rejection. Significantly more transcripts encoding alternative pathway components factor B, C3 and properdin, and C3a receptor and C5a receptor were detected in grade 3 versus grade 0 or 1 biopsies. The grade 3 rejections also contained significantly higher amounts of CD3, interferon gamma, perforin, and granzyme B genes.
