Hydrothermal treatment of MCl2 （ M = Co or Cu ） , NH4 VO3, and 1,10-phenanthroline-5,6-dione （pdon） resulted in the formation of a duplex coordination polymer [ Co （ bpdc ）（ H2O ） 3 ] · H2O （ bpdc = 2,2＇-bipyridine-3,3＇-dicarboxylate） and a chain-like coordination polymer [ Cu （bpy） V2O6 ] （ bpy = 2,2＇-bipyridine ）. X-ray single-crystal structural analysis shows that under hydrothermal conditions and in the presence of different transition metals, the organic reagent pdon was transformed in situ into bpdc and bpy, respectively. Mechanism of the in situ ligand synthesis reaction has been discussed.

作者： WANG Xiu-li FANG Jia-ni BI yan-feng lin Hong-yan LIU Guo-cheng Faculty of Chemistry and Chemical Engineering Liaoning Key Laboratry of Applied Chemistry Bohai University Jinzhou 121000 P. R. China

A new dinuclear complex, [Ag（L）（CH3CN）]2（ClO4）2·2H2O（L=2,3-di-2-pyridylquinoxaline）, was prepared and characterized by elemental analyses, IR spectroscopy, and single-crystal X-ray diffraction analyses. The interaction of the complex with calf thymus DNA（CT-DNA） was investigated by absorption, fluorescence spectroscopies, and viscosity measurement. The results suggested that the complex was bound to DNA via an intercalative mode. The intrinsic binding constant value Kb was found to be approximately 1.48×10^3 L·mol^-1. Moreover, the Ag（I） complex could cleave the plasmid pUC19 DNA from the supercoiled Form Ⅰto the nicked FormⅡ under irradiation at 365 nm.

Objective To clarify the effects of repetitive transcranial magnetic stimulation (rTMS) on rat motor cortical excitabi- lity and neurofunction after cerebral ischemia-reperfusion injury. Methods After determined awake resting motor threshold (MT) and motor evoked potentials (MEPs) of right hindlimbs, 20 Sprague-Dawley rats were subjected to middle cerebral artery occlusion (MCAO) reperfusion injury, then rTMS were applied to rTMS group (n = 10) at different time, while control group (n = 10) received no stimulation. A week later, MT and MEPs were evaluated again, as well as neurological deficits and infarct volume. The effects of rTMS and MCAO reperfusion injury on these parameters were analyzed. Results After MCAO reperfusion, both MT level and neurological deficit scores increased, distinct focal infarction formed, and latency of MEP elongated. Compared with the control group, the increased extent of MT and neurological scores of rats receiving rTMS were significantly lower (P linear correlation between postinjury MT and infarct volume (r = 0.64, P < 0.05). Conclusion rTMS may facilitate neurofunction recovery after cerebral ischemia-reperfusion. Postinjury MT could provide prognostic information after MCAO reperfusion injury.

目的:研究低分子量肝素(LMWH)对妊高征大鼠肾脏损伤的作用及其细胞内信号转导机制。方法:采用注射L NAME方法制备妊高征动物模型,将妊娠大鼠随机分为正常妊娠组、妊高征组、LMWH治疗组,测定各组平均动脉压、尿蛋白、血肌酐及血尿素氮,观察LMWH对肾脏各指标的影响及肾脏出现的病理学变化;同时采用免疫组化、RT PCR及WesternBlot方法检测ERK1/2在各组的表达变化。结果:LMWH治疗组肾脏组织ERK1/2的蛋白及mRNA表达水平明显低于妊高征组(P<0.01),而妊高征组肾脏组织ERK的蛋白及mRNA表达水平明显高于正常妊娠组(P<0.01),ERK1与ERK2在各组大鼠肾脏中的表达无差异;治疗组平均动脉压及尿蛋白明显低于非治疗组(P<0.05),但仍未达正常妊娠水平;HE染色和PAS染色为治疗组肾小球系膜增生、基底膜增厚较非治疗组明显减轻。ERK蛋白主要分布于肾小球中。结论:LMWH对妊高征大鼠肾脏损伤具有一定的防护作用,其机制可能是通过下调ERK1/2的表达来实现。

This paper discusses the performance of some existing interpolation algorithms, andpresents a deterministic perturbation partial volume interpolation algorithm. This algorithm dis-tributes the contribution of intensity of the transformed point to nine entries in the joint histogram,imports and determines the perturbation to calculate the weights. Then it is analyzed and comparedwith other algorithms. The results of experiments indicate that this algorithm can avoid the localextremes on grid points and non-grid points, and e?ectively smooth the object function.

口碑作为老字号的主要传播手段一直备受关注,然而老字号传承是否以及如何对消费者的口碑传播产生影响一直缺乏实证研究。笔者引入真实性概念诠释老字号的传承,基于真实性理论和社会认同理论构建了老字号真实性对消费者口碑传播意向的影响机理模型;以分布在全国各地的307位消费者为调查对象,运用层级回归分析法对真实性影响口碑传播意向的机理模型进行统计检验。结果表明:真实性会提升消费者对老字号的认同,且消费者对老字号的认同会提升其口碑传播的意向,其中,品牌认同在老字号真实性与口碑传播意向两者的关系中起着完全中介的作用;老字号真实性对品牌认同的影响受到消费者代际差异的影响,即消费者年龄越大,其感知的老字号真实性对其品牌认同的影响就越强,反之越弱。我们从品牌真实性的视角探究了老字号口碑形成的内在机理,并进一步揭示了消费者代际差异的调节机制,这对老字号的长期品牌管理有重要的借鉴意义。

Apodisation technology is introduced to optimize fiber Bragg grating based on the analysis of reflectivity spectrum and group delay response of fiber Bragg gratings. The characteristics of Hamming, Gauss and super-Gauss functions are discussed and the optimization effects of the three apodisation functions on ripple smoothness of reflectivity spectrum,group delay and linear degree are compared respectively. As a result,the optimization effects of Hamming function is better than other two functions. When the bandwidth is less than ldB,Super-Gauss function is the best choice and proper parameters （G and m） of super-Gauss function can be selected expediently for wider bandwidth and better ripple smoothness of reflectivitv soectrum.
