为评价反应堆燃料包壳用锆合金管在纯水环境下的腐蚀性能,研究不同热处理工艺对低锡低铌锆合金管的显微组织和腐蚀性能的影响。采用扫描电子显微镜和透射电子显微镜表征了合金的基体组织,并在高压釜中进行了360℃/18.6 MPa纯水环境下长达300 d的腐蚀试验。结果表明:低锡低铌锆合金管在550℃退火、保温5 h后的显微组织为完全再结晶状态,组织形貌为均匀的等轴晶组织,其第二相均匀地分布在晶粒中;而β相水淬+500℃退火、保温5 h后的合金是非完全再结晶的,其组织主要呈板条状。两种热处理温度下制备的低锡低铌锆合金在360℃/18.6 MPa高温高压水中的耐腐蚀性能均优于商用ZIRLO合金。

Salt-tolerant gene, CSRG1, which was isolated from a kind of salt-tolerant mangroves, Avicennia marina, constructed the transgenic plasmid, pGAM189/CSRG1. CSRG1, GUS, Kmr and Hyg^r could be transferred into tobacco genome by the ameliorated leaf discs method of agro-bacterium-mediate transformation. Thirteen stable resistant lines were obtained when fifty transgenic explants were selected through 50 mg/L hygromycin and 150 mg/L kanamycin. Assessments of PCR amplification, Southern blot analysis and GUS histochemical staining showed that CSRG1 has been integrated into the genome of the eleven transgenic lines (frequency of transformation was 22%). Northern bolt analysis revealed that CSRG1 had expressed in transgenic lines. The assessments of salt-tolerant ability and photosyn-thetic rates indicated that the survival rate of the transgenic lines is 80%—90% and the transgenic lines could increase by 30%—40% in plant height, even when they were cultivated in MS medium containing 2% NaCl and the total seawater (salinity 24). It is supposed that the special physiologic metabolic pathway formed by the products of CSRG1 can really endow the tobacco plants with the high salt-tolerant ability, not only to Na^+ stress, but also to the comprehensive stress of various ions.

肺大细胞神经内分泌癌(large cell neuroendocrine carcinoma,LCNEC)是一种罕见且高度侵袭性的高级别神经内分泌癌,患者确诊时分期偏晚,预后差,其治疗策略多借鉴小细胞肺癌和非小细胞肺癌的方案。近年来,二代测序技术为LCNEC的精准分型提供了理论基础,研究也证实了不同LCNEC亚型与化疗方案疗效之间的关联性。免疫检查点抑制剂(immune checkpoint inhibitors,ICIs)的应用,为LCNEC患者提供了新的治疗选择,但相关数据仅见于小样本的回顾性研究和少量个案报道。本文回顾了LCNEC的流行病学特征和经典治疗策略,并针对LCNEC的分子亚型研究进展和ICIs的应用进展进行综述,为临床治疗提供新思路。

Three Cd（II） metal-organic complexes, namely [Cd（phen）2Cl2]（1）, [Cd（phen）Cl2]（2） and [Cd（phen）（cam）]. H2O（3）（phen=1,10-phenanthroline, H2cam=camphoric acid）, were hydrothermally synthesized using Cd2＋, phen and Hacam as raw materials under different conditions of pH values, reaction temperatures or reactant ratios. The prepared complexes were structurally characterized by means of single-crystal X-ray diffraction, and the results show that complex 1 is a 2D supramolecular complex, which consists of [Cd（phen）2Cl2] mononuclear subunits, while complex 2 shows a 1D chain structure, in which Cd（II） ions are connected by chloride（Cl ） bridges, with phen hanging on both sides of the chain. No cam anions have been observed in the structures of complexes 1 and 2. In complex 3, cam connects Cd（lI） ions to construct a 2D network, in which phen acts as terminal ligands. The adjacent 1D chains for complex 2 and the adjacent 2D layers for complex 3 are further linked by hydrogen bonding interac- tions or π-π intermolecular interactions to form 3D supramolecular networks, respectively. The effects of reaction conditions on the assembly and structures of the complexes have been discussed. The fluorescent and photocatalytic properties of complexes 1-3 and the fluorescent sensing behaviors of complexes 2 and 3 have also been investigated.
