| 1 | Immunohistochemical assessment of angiogenesis in hepatocellular carcinoma and surrounding cirrhotic liver tissues显示文摘AIM: To investigate whether vascular endothelial growth factor (VEGF) was over-expressed in hepatocellular carcinoma (HCC) or in surrounding cirrhotic liver tissues.METHODS: Immunohistochemistry was performed to investigate the expression of VEGF proteins in HCC tissues from 105 consecutive patients undergoing curative resection for HCC. The immunostaining results and related clinicopathologic materials were analyzed with statistical methods. Kaplan-Meier method was used to calculate survival curves, and Log-rank test was performed to compare differences in survival rates of the patients with positive HCC staining and negative VEGF.RESULTS: VEGF-positive expression was found in 72 of105 HCC patients (68.6%). Capsular infiltration (P= 0.005),vascular invasion (P = 0.035) and intrahepatic metastasis(P=0.008) were observed more frequently in patients with VEGF-positive expression than in those with VEGFnegative expression. Kaplan-Meier curves showed that VEGF-positive expression was associated with a shorter overall survival (P = 0.014). VEGF-positive expression was found in 47 of tissues 68 HCC (69.1%), and VEGF-positive expression was found in 54 of 68 surrounding cirrhotic liver tissues (79.4%). VEGF-positive expression was significantly higher in surrounding cirrhotic liver tissues than in HCC (P= 0.017).CONCLUSION: VEGF may play an important role in the angiogenesis and prognosis of HCC, as well as in the angiogenesis of liver cirrhosis. | GeertuDeli Can-HaoJin RongMu SongYang YueLiang DeChen MasatoshiMakuuchi | 2005 | World Journal of Gastroenterology2005，11，7： | 19 |
| 2 | Affinely equivalent Khler-Finsler metrics on a complex manifold显示文摘The purpose of the present paper is to investigate affinely equivalent Khler-Finsler metrics on a complex manifold.We give two facts (1) Projectively equivalent Khler-Finsler metrics must be affinely equivalent;(2) a Khler-Finsler metric is a Khler-Berwald metric if and only if it is affinely equivalent to a Khler metric.Furthermore,we give a formula to describe the affine equivalence of two weakly Khler-Finsler metrics. | YAN RongMu School of Mathematical Science,Xiamen University,Xiamen 361005,China | 2012 | Science China Mathematics2012，55，4： | 0 |
| 3 | Parallel Translation on Kahler Manifolds显示文摘In this paper, the author establishs a real-valued function on K?hler manifolds by holomorphic sectional curvature under parallel translation. The author proves if such functions are equal for two simply-connected, complete K?hler manifolds, then they are holomorphically isometric. | Rongmu YAN | 2020 | Chinese Annals of Mathematics,Series B2020，41，3： | 0 |
