查询词典 neoplastic

Apoptosis, or programmed cell death, is a highly conserved, tightly controlledcell suicide process that is regulated by many different intracellular andextracellular events to ablate neoplastic cells in normal physiological functions.

细胞凋亡，又称程序性细胞死亡，是一个高度保守，受机体严格控制的细胞自杀过程，是在许多不同的细胞内外生理事件调控下的清除衰老和突变细胞的正常生理功能。

A neoplastic process, such as inflammatory myofibroblastic tumor or a metastatic malignant tumor, can calcify.

肿瘤，如炎症性成肌纤维细胞肿瘤或者恶性转移性肿瘤，也可由钙化。

Grossly, the tumors ranged from 0.7 to 17 cm, and exhibited a spongy or bubble wrap appearance reflecting the microscopic presence of variably sized cystically dilated tubules lined by a single layer of epithelium. The lining varied with a cuboidal, flat, and hobnail cell appearance, and the neoplastic cells had abundant eosinophilic cytoplasm and enlarged nuclei with prominent nucleoli.

大体上，肿瘤大小为0.7至17cm，海绵样或泡沫样外观，镜下观是大小不等的扩张成囊的管子，这些管子被覆单层上皮，上皮形态立方状、扁平状和鞋钉样，肿瘤细胞胞浆丰富、嗜酸，细胞核大，核仁明显。

The essential events of the process are detachment, intravasation, circulation, arrest, extravasation, angiogenesis and proliferation, which come down to interactions of neoplastic cells with host cells and extracellular matrix -governed by adhesion, migration, invasion, proteaselysis, and the complicated signal transduction.

而所有步骤均可归结为癌细胞与宿主细胞及细胞外基质(Extracellular Matrix，ECM)之间的相互作用——粘附、浸润、移动、蛋白酶分泌以及复杂的信号转导过程，基于细胞信息传递和调控在细胞生命活动中处于主导地位，癌细胞信号转导系统的作用及相关机制对于揭示肿瘤转移的本质，探索新的抗肿瘤转移途径具有十分重要的作用。

Results: The direct signs (such as mural nodule of cystic lesion, solid neoplastic component of solid type、 mixed type tumors enhanced markedly; vascular void signal show with in the tumors) and indirect sign (solid neoplastic component of the tumors close to or adhesion to a pia mater) have some specific manifestations on MR imaging...

结果：血管母细胞瘤的直接征象（如囊肿型的瘤结节，实质性、混合性肿瘤的实质部分明显强化；瘤内出现血管流空信号）及间接征象（肿瘤实质部分邻近软脑膜或与软脑膜有粘连）具有一定的特异性。结论：MR对诊断血管母细胞瘤具有较高的价值。

The fundamental imaging features of osteosarcoma were showed bone destruction, periosteal reaction, neoplastic bone and soft-tissue mass. Among 49 cases examined by radiography, osteoblastic pattern sarcoma was found in 19 cases, osteolytic pattern sarcoma was found in 13 cases and mixed pattern sarcoma was found in 17 cases. The detection rates of bone destruction, periosteal reaction, soft-tissue mass, neoplastic bone and Codman triangle by radiography were respectively 61.2%, 95.9%, 71.4%, 73.5%and 27.7%. All 10 cases with CT scan were showed bone destruction, soft - tissue mass and neoplastic bone. The detection rates of periosteal reaction,憇ieve sign挶 and Codman triangle with CT scan were respectively 90%, 90% and 11%. The tiny neoplastic bone and"sieve sign"were showed sensitively by CT, but Codman triangle was showed by radiography superior to CT.32 cases with MRI scan presented the normal marrow was replaced by the tumor, which was showed low to intermediate signal intensity on T1-weighted images and promiscuity signal intensity on T2-weighted images. 7 cases presented hemorrhage and 24 cases presented necrosis.

骨肉瘤基本影像表现为骨质破坏、骨膜反应、瘤骨和软组织肿块。49例X线表现为成骨型19例，溶骨型13例，混合型17例；X线对骨质破坏、骨膜反应、软组织肿块、瘤骨和Codman三角的检出率分别为61.2%、95.9%、71.4%、73.5%和27.7%；10例CT表现均可见骨质破坏、软组织肿块及瘤骨，CT对骨膜反应、筛孔征和Codman三角的检出率为90%、90%和11%；CT对显示细小肿瘤骨和筛孔征最敏感，但对Codman三角的显示不如X线平片；32例MRI表现为骨髓腔内正常的骨髓高信号被肿瘤信号所取代，T1WI呈低～等信号，T2WI呈混杂信号，7例合并出血，24例中央坏死囊变，32例增强扫描均呈不均匀强化及瘤周可见水肿区。
