脂肪瘤的

MATERIALS AND METHODS The clinical data of 47 cases of patients Underwent laparoscopic adrenectomy and 10 cases of patients underwent open adrenalectomy were analyzed retrospectively.

回顾分析47例腹腔镜肾上腺髓质脂肪瘤切除术和开放肾上腺髓质脂肪瘤切除术的临床资料，统计分析这两种术式在手术时间、术中出血量、术后肠功能恢复时间、术后住院时间及并发症发生率等的差异。

The most frequent preoperative diagnosis was angiolipoma (19.2%), followed by lipoma (16.7%).

最常见的术前诊断是血管脂肪瘤(19.2%)，其次为脂肪瘤(16.7%)。

But caution needs to be observed because even the common lipoma has an invasive form called an infiltrative lipoma.

但是必须谨慎观察，因为即使是普通脂肪瘤有一个外来的形式称为浸润性脂肪瘤。

They are a newly recognized entity of salivary gland lipoma, designated sialolipoma.

这种肿瘤是唾液腺的脂肪瘤中的新分类，称之为含唾液腺脂肪瘤。

Results 7of22cases were angiomyolipoma,6were xanthogranulomatous pyelonephritis,4were multilocular cystic nephroˉma,2were leiomyoma of kidney,2were renal abscess,one case were renal fibrolipoma.

结果 误诊为肾癌的良性占位病变22例，其中肾血管平滑肌脂肪瘤合并出血7例，局灶型黄色肉芽肿性肾盂肾炎6例，肾多发性囊性肾瘤4例，肾平滑肌瘤2例，肾脓肿2例，肾纤维脂肪瘤1例。

Although lipomatosis are painless and pathologically benign, discomfort and disfigurement encourage these patients to seek the removal of such lesions.

虽然多发性脂肪瘤是无痛、良性的，但是不舒服感及畸形的外观，让病患想将这些脂肪瘤移除。

Methods: The clinical materials of different pathological types of intraspinal tumors including neurinoma, meningioma,glioma, angioma and lipoma were comprehensively studied on 77 patients.

系统分析了77例原发性椎管内肿瘤，包括神经鞘膜瘤、脊膜瘤、胶质瘤、血管瘤和脂肪瘤等几种不同病理类型肿瘤的临床资料。

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。

Of the 39 patients, 14 were diagnosed as having renal cell carcinoma preoperatively, 1 as having perinephric liposarcoma, and the remaining 24 as having an angiomyolipoma.

肾旁恶性脂肪瘤，剩余二十四位肾血管肌脂肪瘤。影像学诊断的敏感度是百分之六十一点五。

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。
