To study the effect of nematode-induced forest succession on avian communities, we chose three forest types at different seral stages, including evergreen broad-leaved coppice infested by the pine wood nematode for five years and evergreen broad-leaved forest infested for 12 years, both from Xiangshan County, Zhejiang, and one 40-year-old evergreen broad-leaved forest from Tiantong National Forest Park, Zhejiang.

为了探讨在松材线虫侵袭所引起的森林演替过程中植被结构变化对鸟类群落的影响，我们研究了这此常绿阔叶演替林中的鸟类群落结构。2004年5-6月，我们在浙江省宁波市选择了分别处于3个不同演替阶段的7个样地：包括象山县被松材线虫侵袭5年后的常绿阔叶灌丛和侵袭12年后的常绿阔叶林样地各3个，同时在天童国家级森林公园选择了约40龄的常绿阔叶林样地1个。

The mechanism probably is that Pishang can inhibit the growth, movement and adheresion to extracellular matrix and endothelial cell of liver tumor cells, up-regulate the expression of nm23, down-regulate the expression of CD44, MMP-2, and inhibit the tumor neovascular by supressing the vascular endothelial cell, down-regulating the expression of VEGF, damaging the primitive mesenchymal cells and inhibiting neovascular gemmation.

砒霜具有明显的抗肝癌细胞作用，并有一定的抗侵袭与转移作用，其机制可能与其能抑制肝癌细胞增殖、迁移、阻止肝癌细胞与细胞外基质和内皮细胞粘附、上调肿瘤转移抑制基因nm23表达、下调肿瘤侵袭分子CD44、MMP-2表达以及通过抑制内皮细胞增殖、下调VEGF表达、损伤间充质细胞、阻止新生血管芽生等途径从而抑制肿瘤新生血管形成有关。

运用改良的侵袭实验筛选膀胱癌细胞系的高侵袭力亚系的方法是可靠的，建立的高侵袭力亚系细胞为今后对膀胱癌侵袭及转移的研究提供了较为可靠的细胞模型。

All cases were invasive-7 into at least the lamina propria, 7 into at least the muscularis propria, and 3 into perivesical fat.

所有病例都具侵袭性，至少侵袭至固有膜和固有肌层的各有7例，3例侵袭至膀胱周边脂肪组织。

Methods Samples from 78 patients with pituitary adenomas, including 37 invasive and 41 noninvasive, and 5 normal pituitary tissue specimens from autopsied patients were examined. The expressions of OPN mRNA and OPN were examined by real-time fluorescence quantitative PCR and immunohistochemical SP method, respectively.
