脂肪软骨瘤

Results 14 cases were treated with surgical operation, in which adenoma were 2 cases , papilloma were 5 cases, leiomyoma were 3 cases, chondroma was 1 case, lipoma was 1 case, neurofibroma was 1 case and mixed tumor was 1 case.

结果 14例均行手术治疗，腺瘤2例，乳头状瘤5例，平滑肌瘤3例，软骨瘤1例，脂肪瘤1例，神经纤维瘤1例，混合瘤1例。

Resulte: In 12 infective lesions, including purulent infection (4 cases) and tuberculosis (8 cases), the correct dignosis was made in 4cases by CR and in 11 cases by CT. In 16 soft tissue tumors, including lipoma (7 cases), fibrosarcoma (4 cases), hemangioma (1 case), neurofibroma (1 case), malignant fibrous histocytoma (1case), aggressive fibromatosis (1 case) and liposarcoma (1 case), the correct diagnosis was made in 3cases by CR and in 14 cases by CT. In 11 bone lesions, including fibrous dysplasia (7 cases), chondroma (2 cases), myeloma and cosinophilic granuloma (1 case), the correct diagnosis was made in 8cases by CR and in 10 cases by CT.

结果：感染组12例中(包括化脓性感染4例，胸壁结核8例)，CR准确诊断4例，CT诊断11例；软组织肿瘤组16例中(包括脂肪瘤7例，纤维肉瘤4例，血管瘤、神经纤维瘤、恶性纤维组织细胞瘤、侵袭性纤维瘤病和脂肪肉瘤各l例)，CR准确诊断3例，CT诊断14例；骨肿瘤和肿瘤样病变组11例中(包括骨纤维异常增殖症7例，软骨瘤2例，多发性骨髓瘤和骨嗜酸性肉芽肿各1例)，CR准确诊断8例，CT诊断10例。

It can occur within the lung parenchyma or in an endobronchial location.

在肺部，传统的错构瘤表现为含有软骨和脂肪组织的边界光整的肿块，可发生在肺部实质，也可发生在支气管内。

We found that 1 mutant EG4 cells showed typical characteristics of pluripotent stem cells which had no obvious difference with wild cells; 2 When induced by 10〓 M retinoic acid , mutant EG4 cells differentiated into adipocytes with high frequency compared with mutant cells, suggested that EGFR plays a role in adipocyte differentiation; 3 when injected into nude mice, mutant teratocarcinomas contained a large amount of connective tissues as well as skeletal muscle, while wild EG4 cells produced frequently cartilage, keratinocyte and neuroepithelium.

我们建立了稳定表达胞内区功能缺失的外源EGFR cDNA片段的EG4细胞，分析其生长分化特性，发现 1）突变型细胞可在未分化状态下维持长时间的增殖，表明EGFR对EG多能干细胞表型无明显影响；2）〓 M的维甲酸A(retinoid acid A，RA)诱导后，大部分对照组细胞分化为脂肪细胞，而突变型细胞分化为脂肪细胞的比例明显较少，表明EGFR在脂肪细胞的发育分化中具有一定的调节作用；3）畸胎瘤切片分析显示，突变型瘤组织分布有大量的未分化细胞和结缔组织，分化细胞以肌肉细胞为主；对照组瘤组织含丰富的角质上皮、软骨、神经管等依赖EGFR的分化组织。

PPO gene was not detected in the multiple myelome、 malignant fibrous histiocytoma 、malignant lymphoma、malignant neurosarcoma、solitary plasmacytoma of bone、primitive neuroectodermal tumors、lipoma、 osteosarcoma and sarcoenchondroma.

PPO基因在多发性骨髓瘤、恶性纤维组织细胞瘤、恶性淋巴瘤、恶性神经肉瘤、孤立性浆细胞肉瘤、原始神经外胚瘤、脂肪瘤、骨及软骨肉瘤等肿瘤中没有表达。在骨巨细胞瘤中有微弱表达。

No matter what kinds of sarcomatous elements are found in a retroperitoneal dedifferentiated liposarcoma, its clinical behavior is not the same as high grade fibrosarcomas, leiomyosarcomas, osteosarcomas, chondrosarcomas, rhabdomyosarcomas, or MPNST.

无论在腹膜后去分化型脂肪肉瘤中发现何种类型的其他肉瘤成分，它的临床行为都与高级别纤维肉瘤、平滑肌肉瘤、骨肉瘤、软骨肉瘤、或恶性外周神经鞘膜瘤不同。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
