These results indiacated that tranferring macrophages combinedwith cytokines could be a new adoptive immunotherapy protocol foradvanced cancer,and rTNF used in vivo locally could induce andactivate macrophages to kill tumor cells.Monocytes when activatedunderwent a series of phenotypic and functional changes includingthe expression of IL-2R which may provide an important immunoregu-latory pathway.The presence of lectin-like molecules on thesurface of monocytes and tumor cells may bring theeffector/target cells together,thus facilitating the inductionof apoptosis in target cells by triggering the production ofcytolytic factors and the modification of target of targer cell surface anti-gens.(such as HLA-DR).

综合以上结果可以得出以下结论：转输巨噬细胞并结合细胞因子的联合应用是肿瘤继承性免疫中的又一新的、有潜力的方法；抗肿瘤细胞因子rTNF可通过激活巨噬细胞在体内抑制对其不敏感的肿瘤细胞的生长；人单核细胞在一定条件下激活后，可表达IL-2R，进而一方面增强其自身对IL-2的敏感性，另一方面在体内也具有调节T细胞功能的作用；单核细胞和肿瘤细胞上存在的凝集素类受体可促使两种细胞之间在凝集素介导下相互接近，并诱发单核细胞产生细胞毒因子，以及通过调节靶细胞上表面抗原的表达，促进诱导靶细胞的细胞凋亡。

Many new detection techniques are proposed, that include: To overcome the faults of cross-terms and short unambiguity range for the common Wigner-Ville Distribution , short-time Fourier transform and Gabor transform are applied to SAR moving target detection. To improve the detection performance of WVD in noise environment, a new technique based on the Cross-WVD is proposed. The application of fractional Fourier transform to chirp signal detection is analyzed and extended to SAR moving target detection. To eliminate the restriction of chirp-Fourier transform, a new modified definition is proposed and applied to SAR moving target detection. To detect multiple moving targets whose scattering intensities are different heavily, the CLEAN technique is combined with the above techniques and the ideal detection performance is achieved. At last, the whole dissertation is concluded.

The transition radiation faculae on the rear side of a 20m thick target Ta was a smooth round structure with the center brighter than the periphery, indicating incoherent transition radiation and coherent transition radiation, which is close to the results of the theoretical simulations. For a 100m thick target Ta, the faculae was a star-structure and became smaller, which resembles a star-structure of the energetic proton emission. For a 10μm Ta+10m Cu+5m Ta composite target, the faculae was a ring structure and became bigger and non-uniform, looked like two apart faculae.

在厚度为20μm的Ta靶背表面观测到渡越辐射光斑呈现较平滑的圆形结构，而且中心亮度高于周围，这包含了非相干与相干渡越辐射的成分，与理论模拟结果接近；在厚度为100μm的Ta靶背表面观测到渡越辐射光斑呈现出星状结构，光斑较小，与高能质子发射出现的星状结构极其相似；在复合靶背表面观测到渡越辐射光斑虽然也呈现大致的圆形结构，但光斑较大，而且极不均匀，中间有很明显的光斑分裂。

It is widely known that during the development of nervous system, the synapse between neurons and target tissues plays an important role in the survival and maturation of neurons because target tissues or target cells can produce and secrete many kinds of neurotrophic factors and neuroinductive factors which can promote the growth, differentiation and migration of innervating neurons.
