基于事件驱动体系结构的MTAIS优势分析

传统会计体系结构只采集业务事件的财务度量结果,不能提供及时的信息,不能延伸到企业 的其他各业务部门,不能提供整体性信息。随着信息技术迅速发展,这种局限性日益显著。事件驱动体系 结构(EDSS)基于业务过程和事件构造系统,以业务事件为中心组织数据,能够克服上述缺陷。基于此的 MTAIS,与传统MTAIS相比,在数据传输、整合、共享以及提供财务报告方面具有极大的优势。

Prospects of microwave-induced thermoacoustic imaging

Microwave-induced thermoacoustic imaging(MTAI)has advantages including the large imaging depth,high imaging resolution,high imaging contrast,and fast imaging speed.The thermoacoustic(TA)group of South China Normal University has dedicated to developing TA imaging for more than a decade and has made many breakthroughs.This review introduces these breakthroughs from two aspects including the improvement in techniques and the exploration of applications.On the technological level,there are ultrashort microwave pulse(USMP)-inducedTA imaging that can improve the imaging resolution,nonlinear thermoacoustic imaging(NTAI)that can improve the imaging contrast,polarized microwave-inducedthermoacoustic imaging(P-MTAI)that can obtain cellular-level alignment information,and more convenient and accurate handheld and multimodal probes.On the application side,the optimization and expansion have been carried out,mainly concentrating on breast and myocardial imaging.Finally,several current research directions are introduced,including the application of P-MTAI on joint imaging and research on whole-body imaging of small animals.

MTAl蛋白在非小细胞肺癌中的表达及临床意义

目的探讨转移相关基因1（metastasis—associatedgene 1，MTA1）蛋白表述与非小细胞肺癌生物学行为之间的关系。方法采用免疫组织化学SP法检测78例非小细胞肺癌组织MTAI蛋白的表达。结果①非小细胞肺癌细胞核MTA1蛋白高表达显著高于癌旁肺组织和正常肺组织；（参MTA1蛋白在Ⅲ期的高表达率为82．9％（29／35），显著高于Ⅰ～Ⅱ期58．1％（25／43），P〈0．05；③有淋巴结转移组的非小细胞肺癌中的高表达率为86．2％（25／29），显著高于无淋巴结转移组的59．2％（29／49），P〈0．05。结论MTA1蛋白高表达可能在非小细胞肺癌发生中起重要作用且与淋巴结转移和临床分期密切相关。
