It is expected that the construction of urban landscape may return to its aesthetic value,practical value,ecological value and other aspects of value orientation. It is believed that the urban landscape is both a type of perception and experience. It can not only maintain the cultural heritage and the evolution of civilization,but also maintain the integration of the biological and physical environment,play the role of diversification in the urban public open space,and undertake social functions such as ecological,disaster prevention,waterlogging,and water conservancy at the same time of protecting and lighting the environment.展开更多

The results of 3-dimensional reconstructed images were compared with the final diagnosis and the pathological stages. Results According to 3-dimensional reconstructed images, among the 15 cases, 12 cases of bladder cancer were diagnosed, and the pathological types were transitional carcinoma. Two cases were diagnosed as benign tumor (leiomyoma), and the other one was colon cancer, which invaded bladder. The accuracy was 100% . The clinical stages were determined. Of the 12 bladder carcinomas,5 was in stage T1, 3 in T2,, 3 in T3 and 1 in T4.The accuracy of staging was up to 83% (10/12) compared with pathological stages. Conclusion The 3-dimensional reconstructed technology may improve the accuracy of staging of bladder carcinoma, and to provide important evidence for surgery options. 3 refs,2 figs.展开更多
