Nodus lymphaticus metabasis is an important index for tumor stage and a prognosis.Lymphatic vessel formation plays an important role in pathologic state.

淋巴结转移是肿瘤分期的重要内容和预后指标，淋巴管生成对肿瘤淋巴结转移等具有十分重要的作用。

It has foundβ1,4-GalTⅠas a recognition molecule participated in the adhesion and spreading of cell, recognition of sperm-ovum, growth of nerve neurite, the formation of tissue and tumor metabasis as an adhesive molecule. Embryo implantation is similar to tumor metabasis and invasion.

细胞表面的β1，4-GalTⅠ作为一种黏附分子，参与细胞黏附、铺展、精卵识别、神经轴突生长、组织形成和肿瘤转移，而胚胎着床与肿瘤转移、侵袭过程非常相似。

Tumor metastasis is the primary cause of death of cancer patients.

肿瘤转移是导致肿瘤患者死亡的主要原因。

New vessels is the base of the growth and metastasis of tumor.

新生血管的形成是肿瘤生长和转移表达肿瘤生物学特征的基础。

Curvilinear calcification suggests an aneurysm but is a less specific finding because it can also occur in craniopharyngiomas and sphenoidal masses. The intense enhancement of the residual lumen is relatively specific, but differentiation from other masses may be difficult on CT scans depending on the timing and degree of vascular enhancement. The MR imaging features are usually diagnostic, although they can be very subtle [2]. Significant signal heterogeneity is seen with T1 hyperintense signal due to subacute thrombus or flow related enhancement. Areas of T2 hypointensity can be seen due to intracellular deoxy or methemoglobin, calcification, or flow void.

线样钙化提示动脉瘤，但不是一个非常特异的征像，因为这也可以见于颅咽管瘤和蝶骨肿瘤，管腔样明显强化更特异些，但是在CT上与其他肿瘤鉴别可能是困难的，因为这取决与增强的时间与血管强化的程度，MR的特征性表现是更具有诊断意义的，即使有时候可能表现的非常细微，在T1上可以看到明显的不同信号成分，这是由于亚急性的血栓或流动相关增强效应，T2序列上可以看到低信号区域，这是由于细胞内脱氧或高铁血红蛋白，钙化，或流空效应。

Objective To study the implication of tumor cells' methionine dependence in promoting the effects of chemotherapy.

目的 探讨肿瘤细胞的甲硫氨酸依赖性在提高肿瘤化疗疗效方面的作用及意义。

They analyzed 45 of these new genes in both normal and cancerous tissues from the same patients and found that many of the genes were methylated specifically in the tumor samples.

他们分析了这些新基因中的45种，通过检测来自于同一个患者的正常组织和肿瘤组织发现，许多基因发生了甲基化，尤其是在肿瘤组织标本中。

DNA methylation is atracting more and more attention in the research of tumor and its diagnosis and cure.

DNA 甲基化在肿瘤发生发展机制的研究及肿瘤的诊断与治疗中越来越受到重视。

Recently, people found that pancreatic and other cancer cells could express FOXP3 by itself in microdissection.

最近，人们采用肿瘤组织显微切割等技术研究发现胰腺癌及其它肿瘤细胞本身也存在FOXP3的表达。

And we can use the presence of TNFα as a marker to tell us which tumors will respond to the Smac mimetic alone.

并且，通过了解是否需要肿瘤坏死因子α，我们可以知道哪些肿瘤会对Smac模拟分子单独作用敏感。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
