畸胎瘤的

Methods Two cases of AT/RT were studied by hematoxylin-eosin, reticulin and immunohistochemical staining.

目的 探讨中枢神经系统非典型畸胎样／横纹肌样瘤的临床病理特征、诊断及鉴别诊断。

Results Histologically, AT/RT was characterized by the presence of rhabdoid cells associated with various degrees of primitive neuroectodermal, epithelial or mesenchymal differentiation.

结果 非典型畸胎样／横纹肌样瘤具有特征性的横纹肌样细胞，伴有不同程度的原始神经外胚叶、上皮和间质分化。

RM has special morphological characteristics; it should be differentiated from gemis tocytic astrocytoma, atypical teratoid/rhabdoid tumor, and malignant melanocytoma.

RM有特殊的组织学特点，应注意与胖细胞型星形细胞瘤、非典型畸胎样瘤/横纹肌样瘤、恶性黑色素瘤等鉴别。

For tumors which have been well sampled and exhibit (1) a microcystic pattern and regions with lobulated cellular masses with intervening, sometimes hyalinized fibrous stroma,(2) an absence of morphologic features enabling any other specific diagnosis in the sex cord-stromal category,(3) an absence of epithelial elements, and (4) an absence of teratomatous or other germ cell elements, we propose the designation microcystic stromal tumor.

我们很好地抽样调查了4例肿瘤，显示：（1）微囊样式和有时插入玻璃样变的纤维间质中的分叶状细胞团区，（2）能造成在性索间质这个大类中其他具体诊断的形态特征缺失，（3）上皮成分缺失，（4）畸胎或其他胚芽细胞成分缺失，我们提议定其名为微囊性间质瘤。

Compared with the nine cases of benign teratomas, the four malignant GCTs showed overwhelming male dominance, advanced symptoms at presentation, and poor outcome.

和其他九位成熟畸胎瘤病人比较，恶性生殖芽细胞肿瘤的病人有显著的男性病患倾向，明显的症状及较差的预后。

After prolonged culture, the cells formed teratomas when injected into seere combined immunodeficient beige mice and expressed markers characteristic of undifferentiated human ES cells.

经过长时间的培养，在注射到合并严重免疫缺陷的beige小鼠体内后，这些细胞仍可形成畸胎瘤并表达未分化的人ES细胞的特征性标记物。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
