Astrocytoma is one of the most common malignant brain tumors, and is also the most common glioma type of pathology.

星形细胞肿瘤是人类常见的恶性脑肿瘤之一，也是脑胶质瘤中最常见的病理类型。

1、The Entropy、Smoothness、Uniformity and Relation (base on co-occurrence)are significantly difference between the patients and volunteers(p.05).2、The Contrast (base on co-occurrence matrices) and Distance (based on autocovariance coefficients) tend to be higher volunteers, but not reaching statistical significance.3、Among all the thirty-nine features, the most significant difference was obtained using Relation with the pixel distance varied from 1 to 3 pixels.

本实验使用纹理分析的方法研究正常膀胱壁组织和膀胱赘生物组织的纹理特征，并筛选出四种存在显著统计学差异的纹理特征，为后续利用纹理特征研究膀胱肿瘤浸润肌层深度提供了依据。另外，如前所述，目前膀胱肿瘤的诊断主要依靠膀胱镜，但作为一种侵入性操作，膀胱镜并不适合人群疾病普查和患者的治疗后随访。

Automatic measuring the size of tumour in MRI images is very important, the key technique is edge detection of the tumour.

肿瘤大小的自动检测十分重要，其中的关键技术是检测出肿瘤部位的封闭边缘。

Therefore, regulating the activities of autophagy may be a new target of cancer therapy.

因此，通过调节自噬活性治疗肿瘤可能成为肿瘤治疗领域的一个新靶点。

In the incidence and development of cancer, both out of tumor cell cycle control and autophagy change are closely related to the pathway.

在肿瘤的发生发展中，该通路与肿瘤细胞周期失控和自噬等方面有着紧密的内在联系。

Results: Compared to that of the control group,the growth velocity of tumors of radiation group and AZT plus radiation group was obviously suppressed.

结果：与对照组相比，放射组和AZT+放射组肿瘤生长速度受到明显抑制(P.05)，提示放疗、AZT联合放疗均能抑制肿瘤生长，且后者抑瘤率显著高于前者(P.05)。

It may be one reason for immune escape of tumor cells that induces the development and metastasis of tumor.

这可能是肿瘤细胞发生免疫逃逸，从而导致肿瘤的发生或者转移的原因之一。

New criteria, known as RECIST (Response Evaluation Criteria in Solid Tumours), were published in 2000.8 Key features of the original RECIST include definitions of minimum size of measurable lesions, instructions on how many lesions to follow (up to 10; a maximum five per organ site), and the use of unidimensional, rather than bidimensional, measures for overall evaluation of tumour burden.

新的标准，也称为RECIST（实体肿瘤的反应评价标准）于2000年出版。最初的TECIST关键特征包括病变最小大小的确定、对随访病变数目的建议（最多10个；每个器官最大5个）、一维而不是二维的使用、肿瘤负荷的总体评价。

Results: There was a clear bimodal distribution of 80 microsatellite instability-high tumours according to the number of methylated promoters, with no tumours showing 3/5 methylated loci.

结果：根据启动子甲基化数目，80例高度微卫星不稳定的肿瘤出现明显的双峰分布，没有肿瘤是3/5的位点甲基化。

肝细胞癌中缺氧诱导因子-1α、热休克蛋白70的表达】；综上所述，肝细胞癌发生后，由于血供不足诱导HIF-1α过度表达，应激状态下产生的HSP70通过减轻缺血性损伤，增加毛细血管的生成及减轻细胞凋亡等途径使肿瘤细胞的增殖、移行加快，促进恶性肿瘤的生长、浸润和转移，使肿瘤细胞在适应缺氧、能量代谢、细胞凋亡及转移中起重要作用。

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.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
