China's Foreign Trade 2004年第5期 42-42页

作者： Wolfgang Mayrhuber Chairman and CEO of Deutsche lufthansa ag

lufthansa customers will in future benefit from a new, additional offer in China. Through a new partnership of the German airline with Shanghai Airlines, starting in May they can reach further destinations in China from Shanghai under lufthansa flight numbers. That will pro-duce advantages such as, for example, the collection of miles in the Miles & More programme.

放射学实践 1993年第2期8卷 48-51页

作者： Willi A.Kalender Peter Vock Arkadiusz Polacin Martin Soucek 刘建斌 Siemens ag Medizinische technik Henkestraβe 127 D-8520 Erlangen. Ph.D 北京博爱医院

螺旋式CT(Sprial-CT)是CT诊断学中的一大进步。用这种扫描方法得到的容积是没有间隙的,以致于器官随呼吸而运动的“小的”病理改变亦不会漏掉,并且可以进行重建。

减少X线诊断中必要的辐射剂量

放射学实践 1993年第4期8卷 183-186页

作者： F.Gudden H.Kuhn 于凌 c/o Siemens ag Bereich Medizinische Technik Henkestr. 127 W-8520 Erlangen. 同济医科大学附属同济医院

在对X线诊断的医疗价值进行评估的同时,还必须考虑电离辐射的生物学效应。医疗技术的进步和现代的胶片-增感屏-系统的进展,在保证或改善照片质量的前提下已经使必要的辐射剂量显著减少。

AIM:To investigate the proteolytic contribution of tumor-associated macrophages(TAM)in tumor invasion,we analyzed whether TAM at the invasive front of small HCC in Abcb4-/--mice show an enhanced expression of MMP-9. METHODS:Liver cryosections of the hepatocellular carcinoma(HCC)invasive front from 12 mo old Abcb4-/--mice were stained for collagen typeⅠand MMP-9 using Alexa488 and Alexa568 labeled secondary ***,the Alexa568 dye was bleached and the macrophage marker F4/80 was visualized using Alexa568 labeled secondary ***, photographs of the invasive tumor front were digitally overlaid and analyzed. RESULTS:After complete bleaching of the primary dye,specific fluorescence staining of a third antigen, here F4/80,was successfully performed on the same histological *** this method,we were able to identify conglomerates of matrix metalloproteinase (MMP-9)expressing macrophages within the tumor capsule of HCC. CONCLUSION:MMP-9 expressing macrophages are involved in matrix remodelling at the invasive tumor front of *** described staining protocol provides a simple yet powerful extension of conventional immuno-histochemistry,facilitating visualization of at least three different antigens plus nuclei in one single histological section.
