腺淋巴瘤

Objective:To investigate the CT and clinical manifestations of adenolymphomas of the parotid gland.

目的：探讨腮腺腺淋巴瘤的CT和临床表现特点。

Results With the expression in normal salivary gland as a standard, low C-erbB-2 mRNA expression was seen in adenolymphoma, basal cell adenoma. However, various degrees of over-expression of C-erbB-2 oncogene mRNA were detected in pleomorphic adenoma, mucoepidermoid carcinoma,acinic cell carcinoma ,adenoid cystic carcinoma ,papillary cystic carcinoma,and myoethelial cell carcinoma.

结果 正常涎腺和涎腺肿瘤中发现不同程度C-erbB-2mRNA的表达，以正常涎腺组织的表达水平为基准，在腺淋巴瘤、基底细胞腺瘤呈现低表达、无表达或与正常涎腺组织表达水平相似，多形性腺瘤、粘液表皮样癌、腺泡细胞癌、腺样囊性癌、乳头状囊腺癌和肌上皮癌则呈现不同程度的过表达。

Results The tumors were divided into three types according to the CT findings. Type I: regular, homogeneous density and well-defined,there were 30 patients, included benign mixed tumor(n=29) and adenolymphomas(n=1); Type II:irregular, heterogeneous dentsity, poordefined, there were 15 patients, included benign mixed tumor(n=7), malignant mixed tumor (n=2),adenolymphomas(n=3), hemagioma(n=2),mucoepidermoid carcinoma(n=1). Type III: irregular and could not definded, there were 7 patients, included malignant mixed tumor(n=2), mucoepidermoid carcinoma(n=2), adenoid cystic carcinoma(n=1), malignant lymphoma(n=1), acinic cell carcinoma(n=1). Conclusion CT have important values in location and qualitative analyses of parotid gland.

结果 肿瘤按CT表现分三类：52例患者中，I类30例，形态规则呈类圆形，密度均匀，边缘清楚，除1例腺淋巴瘤外，29例均为良性混合瘤；II类15例，形态不规则，呈分叶状，密度欠均，边界较清或模糊，其中7例良性混合瘤，2例恶性混合瘤，3例腺淋巴瘤，2例血管瘤，1例黏液表皮样癌；III类7例，形态不规则，边缘无法确定，其中恶性混合瘤2例，黏液表皮样癌2例，囊腺癌1例，恶性淋巴瘤1例，腺泡细胞癌1例。

Objective To investigate CT manifestations of Parotid Pleomorphic Adenoma and Adenolymphoma.

导读：目的探讨腮腺多形性腺瘤及腺淋巴瘤的CT表现特点。

The ultrasonography of the adenolymphoma of parotid gland is mainly based on the characteristics organization of pathology.

结论腮腺腺淋巴瘤声像图特征性表现主要基于其病理组织结构的特点；超声检查结合肿瘤临床资料能进一步提高超声对该病的诊断准确率。

Beside, forty patients with adenolymphoma of parotid gland were studied by ultrasonography and pathology.

目的总结腮腺腺淋巴瘤的声像图特点，结合病理基础、临床特点对照分析，旨在提高其诊断符合率。

Results In all 30 cases ,we found 14 thymoma , 1 ectopic thymoma, 8 invasion thymoma , 2 thymic carcinoid,2 thymic carcinoma, 2 thymic lymphadenoma,1 cervical thymic cyst.

结果 30例患者中，胸腺瘤14例，异位胸腺瘤1例，侵袭性胸腺瘤8例，胸腺类癌2例，胸腺癌2例，胸腺淋巴瘤2例，颈部胸腺囊肿1例。

Objective To investigate the relation between polymorphism of c-myc and k-ras gene and thymic lymphomas of mice induced by ionizing radiation.

目的：探讨c-myc和k-ras基因多态性与辐射诱发小鼠胸腺淋巴瘤的关系。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
