| 1 | Imaging Findings of Hepatic Ewing’s Sarcoma on Computed Tomography and Gadobenate Dimeglumine-enhanced Magnetic Resonance Imaging: A Case Report and Literature Review显示文摘Ewing’s sarcoma(ES)is a tumor that often occurs in the long bones and rarely arises from visceral organs primarily.Here,we report a case of primary hepatic ES,discuss its computed tomography(CT)and gadobenate dimeglumineenhanced magnetic resonance(MRI)features.This is the first Chinese and fifth primary hepatic ES case reported,based on a literature review.Imaging examinations showed that the tumor was solid,with necrosis and hemorrhage.Contrast-enhanced images showed that the tumor was hypervascular and especially had heterogeneous signal intensity on hepatobiliary phase MRI images.Intratumoral vessels and vascular invasion were also present. | Tao Lu Wenhao Yang Xingchao Liu Xudan Yang Chong Yang Wenjia Di | 2022 | Journal of Clinical and Translational Hepatology2022，10，3： | 2 |
| 2 | Mechanochemistry in cancer cell metastasis显示文摘Metastasis is the leading cause of death in people with cancer. In the series of steps comprising metastasis process, mechanochemistry plays crucial roles. In this review, we introduced the mechanical factors in cancer cell metastasis, intracellular mechanical sensors and methods for measuring the mechanical forces of tumor cells. The recent researches on the contribution of mechanochemistry to metastasis and future perspectives were summarized. | Di Zhang Feng Feng Ruping Liu Wenjia Zhu Li Yao | 2019 | Chinese Chemical Letters2019，30，1： | 2 |
| 3 | The Regression Analysis of Tax Competition among Local Governments显示文摘Although the local government in China is still a lack of an independent tax right,the political decentralization makes local interests increasingly prominent,which contributes to the interests pattern of tax competition among local governments in our country.The implementation of the tax-sharing system may promote the local governments to expand virtual tax competition.This paper attempts to explore the nature and extent of the tax competition among local governments in China,using measurement regression with Chinese provincial panel data from the year 2005-2010 based on the spatial econometric model,and make some empirical analysis.The main findings in research are as follows:Different provinces of fiscal revenue show indistinctive spatial characters,while various provinces of VAT,business tax,personal income tax,business income tax show significantly strategy complementary characteristics over the same period of time.We conduct some in-depth discussion and analysis of these findings combining with the actual situation in China. | Di He Wenjia Sun | 2012 | 民营科技2012，，10： | 0 |
