| 1 | 乳腺肿瘤癌变过程中血管生成与VEGF表达相关性研究(英文)显示文摘Objective: The aim of the study was to detect the expression of vascular endothelial growth factor (VEGF) and microvessel density (MVD) in breast benign tissues and malignant tumors to clarify the relationship between VEGF expression, angiogenesis and breast carcinoma occurrence. Methods: The expression of VEGF and MVD in 79 cases of invasive ductal breast carcinoma, 79 corresponding para-cancer normal tissues from primary invasive breast carcinomas, 35 breast carcinoma in situ, 23 breast atypical hyperplasia and 56 breast fibroid tumor were examined by immunohistochemistry staining (SP-method). Results: The positive rate of VEGF and MVD value increased significantly with the increase of the malignant degree of breast tissues (P = 0.000). In breast carcinoma group, the positive rate of VEGF and MVD value with lymph node metastasis were higher than those without lymph node metastasis (P = 0.011 and P = 0.023). A significant higher expression of VEGF and MVD value were observed as the clinical stage increased (P = 0.035 and P = 0.012). The MVD value was higher in VEGF positive group than negative group (P = 0.000). Conclusion: The combining detection of VEGF expression and MVD is helpful for evaluating malignant degree of breast carcinoma. Angiogenesis in breast tumors and occurrence of breast carcinoma might be correlated with the expression of VEGF. | Gang Wang Sanping Zhao Yuzheng Wu Heyong Wang Jianhong Zhao Weiguo Xu | 2010 | The Chinese-German Journal of Clinical Oncology2010，9，7： | 1 |

| 5 | A New Species of Rhodoleia(Hamamelidaceae) from the Upper Pliocene of West Yunnan, China and Comments on Phytogeography and Insect Herbivory显示文摘In Europe, fossil fruits and seeds of Rhodoleia(Hamamelidaceae) have been described from the Upper Cretaceous to the Miocene, whereas no fossil record of Rhodoleia has been reported in Asia, where the modern species occur.Herein, 21 fossil leaves identified as Rhodoleia tengchongensis sp.nov.are described from the Upper Pliocene of Tengchong County, Yunnan Province, Southwest China.The fossils exhibit elliptic lamina with entire margins, simple brochidodromous major secondary veins, mixed percurrent intercostal tertiary veins, and looped exterior tertiaries.The leaf cuticle is characterized by pentagonal or hexagonal cells, stellate multicellular trichomes, and paracytic stomata.The combination of leaf architecture and cuticular characteristics suggests that the fossil leaves should be classified into the genus Rhodoleia.The fossil distributions indicate that the genus Rhodoleia might originate from Central Europe, and that migrated to Asia prior to the Late Pliocene.Additionally, insect damage is investigated, and different types of damage, such as hole feeding, margin feeding, surface feeding, and galling, are observed on the thirteen fossil leaves.Based on the damage frequencies for the fossil and extant leaves, the specific feeding behavior of insects on Rhodoleia trees appears to have been established as early as the Late Pliocene.The high occurrence of Rhodoleia insect herbivory may attract the insect-foraging birds, thereby increasing the probability of pollination. | WU Jingyu ZHAO Zhenrui LI Qijia LIU Yusheng(Christopher) XIE Sanping DING Suting SUN Bainian | 2015 | Acta Geologica Sinica(English Edition)2015，89，5： | 0 |
