    用蛋白酶切技术制备MCAbJHⅢfAb′片段,回收率约10%。片段活性相当于完整MCAb的1102稀释浓度。用氯胺T法标记MCAbJHⅢfAb′,对荷人肝细胞癌bEl-7402裸鼠体内的放射免疫显像进行了研究。腹腔注射131I-MCAbJHⅢfAb′后24~96H,肿瘤部位有放射性浓聚,以48~72H影像最为清晰;而注射131I-MCAbJHⅢ肿瘤部位也有积聚现象,但本底消除更慢。131I-MCAbJHⅢfAb′注射后72H,13种器官的肿瘤组织与非瘤组织的放射性比值均大于3,肿瘤的定位指数为2.56。这表明MCAbJHⅢfAb′在肝细胞癌的诊断和指导治疗方面有更好的应用前景McAb JHⅢFab′ Fragment was prepared with pepsin digestion It′s receiving percentage was about 10% Its titer was 1∶10 2 of McAb JHⅢ McAb JHⅢFab′ Fragment was radiolabeled with 131 I by Ch T method Its distribution and radioimmunoimaging in the nude mice bearing human hepatoma BEL 7402 were studied Between 24-96 h aFter intraperitoneal administration, the image of the concentrating radioacitivity in tumor was obtained by the γ camera and it was the clearest during 48-72 h; whereas the injection of 131 I McAb JHⅢ into the nude mice resulted in an equal radioactivity in tumor, but it′s background was more slowly cleared. At 72 h aFter the injection of 131 I McAb JHⅢFab′, the radioactivity ratioes of tumor/normal tissue(T/NT) For 13 kinds of organ/tissue were all over 3, and the localization index of tumor was 2 56 These results showed that McAb JHⅢFab′ may be useFul in the localization and targeting treatment of human hepatocellular carcinom

    金融服务贸易自由化与金融有效保护

    Get PDF
    在金融服务贸易自由化过程中对国内金融体系实行合理的适度保护,以避免金融业开放对国内金融体系的过度冲击和对民族金融业发展的抑制。政府一方面保持国内金融市场总体对外开放乃至扩大开放的大环境,另一方面又根据本国经济利益的需要,以专项法规的定向约束和管理体系的特别设计为手段,以对国外竞争者设置制度化的市场限制为目的,在金融服务贸易自由化的同时实现对特定领域的局部性保护

    针对运动突变目标视觉跟踪问题,提出一种基于视觉显著性的两阶段采样跟踪算法.首先,将视觉显著性信息引入到WAng-lAndAu蒙特卡罗(WAng-lAndAu MOnTE CArlO,WlMC)跟踪算法中,设计了结合显著性先验的接受函数,利用子区域的显著性值来引导马尔可夫链的构造,通过增大目标出现区粒子的接受概率,提高采样效率;其次,针对运动序列中平滑与突变运动共存的特点,建立两阶段采样模型.其中第一阶段对目标当前运动类型进行判定,第二阶段则根据判定结果采用相应算法.突变运动采用基于视觉显著性的WlMC算法,平滑运动采用双链马尔可夫链蒙特卡罗(MArkO CHAIn MOnTE CArlO,MCMC)算法,以此完成目标跟踪,提高算法的鲁棒性.该算法既避免了目标在平滑运动时全局采样导致精度下降的缺点,又能在目标发生运动突变时有效捕获目标.实验结果表明,该算法不仅能有效处理运动突变目标的跟踪问题,在典型图像序列上也具有良好的鲁棒性.In this paper, a saliency based tracking method via two-stage sampling is proposed for abrupt motions.Firstly, the visual salience is introduced as a prior knowledge into the Wang-Landau Monte Carlo(WLMC)-based tracking algorithm.By dividing the spatial space into disjoint sub-regions and assigning each sub-region a saliency value, a prior knowledge of the promising regions is obtained; then the saliency values of sub-regions are integrated into the Markov chain Monte Carlo(MCMC) acceptance mechanism to guide effective states sampling.Secondly, considering the abrupt motion sequence contains both abrupt and smooth motions, a two-stage sampling model is brought up into the algorithm.In the first stage, the model detects the motion type of the target.According to the result of the first stage, the model chooses either the saliency-based WLMC method to track abrupt motions or the double-chain MCMC method to track smooth motions of the target in the second stage.The algorithm efficiently addresses tracking of abrupt motions while smooth motions are also accurately tracked.Experimental results demonstrate that this approach outperforms the state-of-the-art algorithms on abrupt motion sequence and public benchmark sequence in terms of accuracy and robustness.国家自然科学基金(61373077); 国防基础科研计划(B0110155); 国防科技重点实验室基金(9140C30211ZS8); 高等学校博士学科点专项科研基金(20110121110020)资助~
