Combustion energies and standard molar enthalpies of formation for the complexes of the first-row transitional metal chlorides withL-α-histidine

Seven novel solid complexes of the first-row transitional metal with L-α-histidine were synthesized, and their compositions were determined. The constant-volume combustion energies of the complexes were measured by a precision rotation bomb calorimeter. The standard molar enthalpies of combustion and the standard molar enthalpies of formation were calculated. The results indicated that the plots of the standard enthalpies of formation against the atomic number of the metal show a regularity of zigzag.     

Self reliance and Innovation of Qinshan Phase Ⅱ NPP Project

This article mainly describes the selfreliance and innovation of Qinshan nuclear power project of phase II,inbetween it contains new reactor core design, as well as related experimental and calculation analysis, especially for new reactor design produced fluidinduced vibration model test, theoretical analysis and testing inbuilt reactor; aiming at twoloop NSSS a series improvement made for safety systems and related safety analysis to enhance their reliability and redundancy; according to specialty of twoloop NSSS an optimization made for NPP parameters and design of related equipments, for the purpose to make the output of NPP maximal; design of main reactor building and TG building also improved according to characteristics of twoloop NSSS and site conditions. CRDM and refueling machine are researched and manufactured on base of selfreliance, their performance are better than design requirements, large portion of key equipments are localized through different way. In construction first time realized the integrated erection of containment dome. During the commissioning nonnuclear steam driving of TG set, as well as 500 kV high voltage rising using emergent diesel generator, etc. are carried out. In period of operation still continuous innovation and improvement are made, so that to keep the good record of operation.

恶性肿瘤中IGFBP-rP1的抑癌基因作用机制及其可能的临床实用价值

胰岛素样生长因子结合蛋白相关蛋白1(IGFBP-rP1)是近年来恶性肿瘤的研究热点.本文主要综述IGFBP-rP1在恶性肿瘤中的抑癌基因作用机制及可能的临床实用价值.IGFBP-rP1在恶性肿瘤中的作用广泛涉及细胞的增殖、衰老、凋亡、分化、血管生成等多方面,研究指出IGFBP-rP1可缩短细胞增殖周期并影响非停泊性生长从而抑制增殖,降低致瘤能力;调节BRAF-MEKERK信号通路及pRB、HSP60等相关蛋白的表达从而影响衰老及凋亡;主要通过IGF依赖方式抑制血管生成;而且IGFBP-rP1表达下降跟肿瘤细胞分化程度降低有关.研究显示IGFBP-rP1有一定的临床实用价值,如其表达量跟恶性肿瘤的进展相关,低表达提示某些化疗药物抵抗,可提示预后.而在恶性肿瘤中特异性地上调IGFBP-rP1,可抑制肿瘤增殖及血管生成、诱导细胞衰老凋亡、提高肿瘤分化程度及化疗敏感性,具有治疗意义,但研究者们还在努力探究,争取早日找到一种临床有效的靶向IGFBP-rP1的基因治疗方法.
