摘要：Antibody-based fusion proteins are the next generation of antibody therapies for cancer and other ***20 antigen,which is overexpressed on cell membranes in nearly 95% of cases of B-cell Non-Hodgkin's Lymphoma,is an attractive target for the therapy of B-lymphoid *** (LDM) is a potent enediyne-containing antitumor antibiotic that now has entered phase II clinical *** this study,we prepared an engineered fusion protein,scFv-LDP,consisting of an anti-CD20 scFv fragment and the apoprotein LDP of LDM using DNA *** purification and refolding,scFv-LDP was found to bind specifically to CD20-positive lymphoma cells using ELISA and indirect immunofluorescent cytochemical staining *** energized fusion protein scFv-LDP-AE was obtained using molecular reconstitution of the active chromophore AE of LDM and *** assay revealed potent cytotoxicity of scFv-LDP-AE to CD20-positive Raji and Daudi cells,with IC 50 values of 1.21×10-11 and 6.24×10-11 mol L-1,*** in vivo subcutaneous xenograft model of CD20-positive B cell lymphoma in BALB/c (nu/nu) mice was also *** were given intravenously on day 14 and 21 after tumor *** terms of maximal tolerated doses,scFv-LDP-AE at 0.3 mg kg-1 suppressed tumor growth by 79.3%,and LDM at 0.05 mg kg-1 by 68.6% (P<0.05).Results suggested scFv-LDP-AE could be a potential candidate for tumor-targeting therapy.

摘要：王尔德在塑造道连这一唯美艺术形象之后,艺术追求出现了新的变化,即从他所坚持的唯美主义艺术立场转向现实主义艺术立场。《莎乐美》是王尔德创作的第一部戏剧,也是这种创作转变的明显标志,在其戏剧创作中具有承上启下的作用。王尔德在创作《莎乐美》的时候,虽然主观上仍然企图坚持唯美主义艺术思想,但是他在塑造莎乐美这一艺术形象时,已经逐步地放弃他的唯美主义艺术而向现实主义艺术转变。莎乐美就是王尔德企图在戏剧中塑造的体现其艺术主张的唯美形象,但与此前的艺术形象已经有着本质的不同。王尔德无法通过艺术的手段,把生活在道德现实中的莎乐美塑造成像道连那样的形象,因为他无法消除隐藏在莎乐美身上的道德特征,也无法割断她与道德环境的联系。

摘要：作为一种艺术思潮,后现代主义在小说领域的具体体现之一为高雅严肃小说与通俗小说之间界线的消失,科幻小说因迎合了后现代诗学的这一要求而深受关注。传统的科幻小说在汲取了后现代主义的一些艺术技巧之后,变成具有后现代特色的科幻小说。加拿大作家玛格丽特·阿特伍德的《奥蕾克斯与克雷克》就是这样一部后现代科幻小说。她把传统的科幻主题与戏仿、时间的纷乱、元小说、反讽等后现代主义的创作手法相结合,为科幻小说在二十一世纪的发展指明了方向。

摘要：提出了一种基于星座图设计来实现对矢量信号发生器输出数字调制信号的调制误差进行准确设置的新方法,给出了方法的理论推导过程、方法的实现,以及实验验证。该方法可以用于实现对矢量信号分析仪在非零调制误差处测量准确度的校准,也可以用于数字调制误差参数量值比对传递标准的研制中。
