Interspecific competition between Encarsiaformosa and Encarsia sophia, two major parasitoids of Bemisia tabaci, and the influence of five tomato varieties on competition outcome were investigated under laboratory conditions. E. formosa parasitized more B. tabaci than E. sophia when in single wasp assays on any of the tomato varieties investigated. When B. tabaei nymphs were exposed to both wasp species （either simultaneously or sequentially）, the number of B. tabaci nymphs parasitized by either wasp species was significantly decreased compared to the sole access condition. Total mortality of B. tabaci was increased when B. tabaci nymphs were exposed to both wasp species compared to only one wasp species. Thus competition between *** and E. sophia apparently reduced parasitoid offspring numbers, but not the efficiency of biological con- trol. In fact, control efficiency was enhanced in some cases, particularly on tomato variety Huangtuoyuan （HTY）. When wasps were allowed sequential access to hosts, interference occurred through host feeding by the second wasp, especially if it was E. sophia. The effect of different tomato varieties was not significant.

A new organocatalytic double annulation cascade involving scission/recombination of N-O bonds of nitrones is reported for the first time, and used to produce a range of hitherto unprecedented tricyclic bridged-fused benzo[d]azepines bearing three stereogenic centers with moderate to good yields and complete diastereoselectivity. A quinine-catalyzed reaction of yne–allenone esters with nitrones worked well and provided a convergent and regioselective pathway to access these three-dimensional scaffolds from the planar conjugated system. Density functional theory(DFT) calculations have been applied to understand the key process for forming diradical intermediates.

Objective：To restore cardiac autonomic pace function by autologous trans- plantation and committed differentiation of hone marrow mesenchymal stern cells, and explore the technique for the treatment of sick sinus syndrome. Methods ： Mesenchymal stern cells isolated from canine bone marrow were culture-expanded and differentiated in vitro by 5-azacytidine. The models of sick sinus syndrome in canines were established by ablating sinus node with radio-frequency technique. Differentiated mesenchymal stem cells labeled by BrdU were autologously transplanted into sinus node area through direct injection. The effects of autologous transplantation of mesenchymal stern cells on cardiac autonomic pace function in sick sinus syndrome models were evaluated by electrocardiography, pathologic and immunohistochemical staining technique. Results：There was distinct improvement on pace function of sick sinus syndrome animal models while differentiated mesenchymal stem cells were auto-transplanted into sinus node area. Mesenchymal stern cells transplanted in sinus node area were differentiated into similar sinus node cells and endothelial cells in vivo, and established gap junction with native cardiomyocytes. Conclusion ： The committed- induced mesenchymal stern cells transplanted into sinus node area can differentiate into a- nalogous sinus node cells and improve pace function in canine sick sinus syndrome models.

本论文从刺参中分离纯化得到一种海参肽,并研究其对NIH/3T3细胞增殖和胶原蛋白分泌的影响。采用活性追踪的方法从新鲜刺参中通过离子交换层析、凝胶层析分离纯化得到海参肽SP12,采用MTT法检测SP12对NIH/3T3细胞的增殖作用;采用流式细胞术检测SP12对NIH/3T3细胞细胞周期的影响;采用羟脯氨酸测定试剂盒的方法检测SP12对NIH/3T3细胞胶原蛋白分泌的影响;采用Western Blot及RT-PCR的方法,在蛋白水平及基因水平上检测SP12对NIH/3T3细胞I型胶原蛋白、MMP-1及TIMP-1表达的影响。结果表明SP12能显著提高NIH/3T3细胞的增殖率,能促进NIH/3T3细胞由G1期向S期转变,增加其胶原蛋白的分泌量,且在0~20μg/mL范围内均呈剂量依赖性。在蛋白水平和基因水平,SP12均能显著促进I型胶原蛋白及TIMP-1的表达,抑制MMP-1的表达,这可能是SP12促进NIH/3T3细胞胶原蛋白分泌的作用机制。
