Abiotic stress poses a great threat to plant growth and can lead to huge losses in yield. gene enolase2 （EN02） is important in resistance to abiotic stress in various organisms. ENO2 T-DNA insertion mutant （enoZ） plants of Arabidopsis thaliana showed complete susceptibility to sodium chloride treatment when were analyzed either as whole plants or by measuring root growth during NaCl treatment. Quantitative real-time RT-PCR （RT-qPCR） was performed to investigate the expression profile of EN02 in response to NaCl stress in Arabidopsis. The transcript level of EN02 was rapidly elevated in 300 mmol L-1 NaCl treatment. ENO2 also responded to 300 mmol L 1 NaCl treatment at the protein level. To illuminate the mechanism underlying EN02 resistance to salt at the transcriptional level, we studied the wild-type and enoZ Arabidopsis lines that were treated with 300 mmol L 1 NaCl for 18 h using 454 GS FLX, which resulted in an expressed sequence tag （EST） dataset. A total of 961 up-regulated and 746 down-regulated differentially expressed genes （DEGs） were identified in the pairwise comparison w-r-18 h：eno2^-18 h. The DEGs were identified and functionally annotated using the databases of gene Ontology （GO） and the Kyoto encyclopedia of genes and genomes （KEGG）. The identified unigenes were subjected to GO analysis to determine biological, molecular, and cellular functions. The biological process was enriched in a total of 20 GO terms, the cellular component was enriched in 13 GO terms, and the molecular function was enriched in 11 GO terms. Using KEGG mapping, DEGs with pathway annotations contributed to 115 pathways. The top 3 pathways based on a statistical analysis were biosynthesis of the secondary metabolites （KO01110）, plant-pathogen interactions （KO04626）, and plant hormone signal transduction （KO04075）. Based on these results, EN02 contributes to increased resistance to abiotic stress. In particular, EN02 is involved in some of the metabolic stress response pathways in

A series of 2-acyl-β-lactam-2-carboxamides was prepared through a tandem Ugi 4 CC/SN cyclization of bromoacetic acid, primary amine, arylglyoxal, and isocyanide. All of them were characterized by NMR, IR, MS and elemental analysis. Meanwhile, the single crystal of compound 5 a, C_(19)H_(25)ClN_2 O_3, was also obtained and determined by X-ray crystallography. Crystal data: triclinic system, space group P_1, a = 8.1318(15), b = 11.931(2), c = 12.027(2) ?, α = 67.361(3)°, β = 73.009(3)°, γ = 85.663(3)°, V = 1029.1(3) ?3, Z = 2, F(000) = 388, Dc = 1.178 g/cm3, μ = 0.204 mm^(-1), R = 0.0786 and w R = 0.2212 for 3585 independent reflections(Rint = 0.0214) and 2960 observed ones(I > 2σ(I)). Intermolecular N–H···O stacking interactions contributed to the stability of the structure. The antitumor abilities of 5 were analyzed with 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazo-liumbromide(MTT) standard method; 5 c stood out as the most potent showing an IC_(50) of 1.70 μmol/L against human tumor cell lines(HepG2).

实施马克思主义理论研究和建设工程,是党最根本的思想建设。毛泽东加强党的执政能力建设思想的重要内容之一,就是坚持把党的思想建设放在首位。而思想建设的基础就是加强理论学习,不断提高马克思主义理论素养。为探索中国自己的革命和建设道路,实现马克思主义与中国实际的结合,毛泽东要求全党特别是党的高级干部,要充分认识到提高马克思主义理论素养的重要性,必须“系统地而不是零碎地、实际地而不是空洞地”学习马克思主义基本原理,掌握理论武器,指导中国实践。毛泽东提倡学习马克思主义基本理论要在原著上下功夫,为我们树立了典范。
