Investigation of ductal carcinoma of no special type reveals covert tumour types, such as those with basal or myoepithelial features, whose distinctive features are only now being widely recognised.

对非特殊类型导管癌的研究揭示了隐藏的肿瘤类型，例如一些具有基底或肌上皮特征的肿瘤，它们的显著特征现在才被广泛认识。

Results Myoid/myofibroblastic differentiation occurred most commonly in fibrosarcomatous DFSP. It was recognized histologically as peripherally distributed or randomly scattered small eosinophilic nodules or short bundles, which were composed of bland spindle cells, closely resembling smooth muscle cells or myofibroblasts.

结果 肌样／肌纤维母细胞性分化多出现在纤维肉瘤型DFSP中，表现为肿瘤周边部或肿瘤内散在性分布的深嗜伊红色小结节或短条束，由梭形细胞组成，细胞多无异型性，核分裂象也罕见，形态上似平滑肌细胞或肌纤维母细胞。

Such benign smooth muscle tumors of the myometrium are very common, perhaps 1 in 5 women has one.

此种良性的子宫平滑肌肿瘤是非常常见的，大约5个妇女里有一个人有一个肿瘤。

Based on the results of 1H-NMR, 13C-NMR, ESI-MS and UV spectra, the structures of three compounds with antitumor activity were identified as Prodigiosin、7-Hexadecenoic acid、7,10-Octadecadienoic acid, respectively; another compounds (no activity to above tumor cells)was identified as Myristic acid.

运用核磁共振（1H-NMR、13C-NMR）、质谱、紫外光谱等现代波谱技术分析，将其中3种具有抗肿瘤活性的化合物分别鉴定为灵菌红素、7-十六碳烯酸（7-Hexadecenoic acid）、7，10-十八碳二烯酸（7，10-Octadecadienoic acid）；鉴定另一种对上述肿瘤细胞无活性的化合物为肉豆蔻酸。

The tumors occurred in 28 males and 54 females (5 to 22 y of age) and involved many locations. Fifty-six cases were typical myxoid liposarcomas, including 2 with round cell areas.

患者为28名男性、54名女性，年龄5岁至22岁，肿瘤发生部位多样。58例肿瘤是典型的黏液样脂肪肉瘤，其中2例伴圆形细胞区。

Methods Expression of Ang2 was determined in 30 cases of JNA and 20 cases of chronic inflammation tissues of the pharynx nasalis by immunohistochemistry.

目的 初步探讨血管生成素2（Ang2）在鼻咽血管纤维瘤中的表达及其与肿瘤的血管生成和肿瘤扩展性生长的关系。

Hypoxia is an important characteristic of neoplasma and some other diseases. For this reason, it is becoming an attractive research area to inhibit tumor growth by utilizing the hypoxia environment.

缺氧是包括肿瘤在内的许多疾病的重要特征，利用缺氧条件来选择性抑制肿瘤生长和演进是一个很有前途的研究方向。

Simultaneously 15 samples of normal nephric tissue were used as control.The sections from these samples were subjected to immunohistochemical analysis with antibodies directly against uPA and PAI-1 by LSAB method. In this study we adopt semiquantitative analysis to determined the expression of these molecules , and utilized the relevant data processing and statistical analysis to evaluate the correlation between their expression and the clinicopathological features of RCC.Results: 1. The positive rate of uPA and PAI-1 of uPA in RCC were 72%(36/50)and 56%(28/50), respectively.But in control group there was nearly

正常肾组织标本中几乎无阳性染色。2、uPA表达水平与患者年龄、性别、肿瘤病理分级无关(均P＞0.05)，与T分期、淋巴结转移有明显的相关性(r=0.684，P＜0.05；r=0.789，P＜0.05)，uPA高表达多见于T_(3-4)、有转移的RCC.3、PAI-1的表达水平与患者年龄、性别、肿瘤病理分级和T分期无关(P＞0.05)，与淋巴结转移有明显的相关性(r=0.800，P＜0.05)，PAI-1高表达多见有转移的RCC.4、对uPA和PAI-1行相关性检验，uPA在RCC中的表达与PAI-1的表达呈明显正相关(r=0.168，P＜0.05)。5、uPA和PAI-1的表达与淋巴结转移的关系以Logistic回归法进行分析，结果显示uPA与区域淋巴结转移密切相关，uPA是淋巴转移的危险因子(RR=2.718，95％CI=1.150～7.170，P=0.024)，PAI-1则不是淋巴转移的危险因子(RR=1.599，95％CI=0.624～4.102，P=0.328)。

Results A total of 5 patients with intramedullary spinal neurinoma were treated with total resection.

结果 本组5例均行肿瘤全切除手术，采用气管插管静脉复合麻醉，术中可见5例肿瘤皆有包膜，与周围脊髓界限清楚。
