A circumferential array of cleats, which each have the form of a comb, support and guide the terminal leads circumferentially, spaced from one another, to a certain location at the top from which the leads are taken and connected to terminals above.

布置成圆周形阵列的梳状线夹(35)在周向上支撑和引导端子引线(34),使端子引线的顶部彼此间隔开一定的距离,从顶部引出的引线连接到上面的端子上。

The available operation range in clivus and anterior cranial base by transsphenoidal opproach was also observed during the operation under the help of neuronavigational pointer. Forty-one patients underwent sublabial, transseptal, transsphenoidal approach to the pituitary region guided by Surgical Microscope Navigation was studied. The piriform aperture was 27. 2mm±3. 1 , the origin of inferior nasal concha 30mm±4. 1, the origin of middle nasal concha 27. 9mm±4. 3. These data are important for transsphenoidal approach, because the piriform aperture and the origin of both inferior and middle nasal conchas restricted the opening width of the Hardy specula. If any distance of these bony structures was much less than the mean one, may cause inadequate opening of the specula blade and resulting dissatisfied operative field. Microadenomas or cystic tumors perhaps can be operated even in a narrow exposure, but large or giant solid adenomas may need a proper evaluation including changing the operative approach or performing a bilateral submucous inferior conchotomy or posterior ethmoidectomy firstly.

手术中还利用CT导航系统观察棒研究了经口—鼻蝶窦入路在斜坡区和前颅底能够达到的实际有效操作范围,为扩大经蝶窦入路手术在斜坡区和前颅底的应用奠定基础,在国内外尚未见同类报道。41例垂体瘤患者梨状孔平均宽度27.2mm±3.1,下鼻甲根部附着处间距30mm±4.1,中鼻甲根部附着处间距27.9mm±4.3,这是经口—鼻蝶窦入路手术中,对Hardy双瓣鼻窥器张开限制的主要骨性结构,若患者这些径线值明显小于平均值,则可能因为鼻窥器打开不充分而影响手术暴露,当然对于垂体微腺瘤和以囊变为主的垂体瘤可能影响不大,但对于大和巨大垂体瘤必须要有充分的准备,包括评估是否改用其他入路,或先行鼻甲切除再行经蝶手术。

Methods A retrospective analysis of paranasal coronal computedtomography scans of 200 sides from 100 patients were performed. The junction point between vertical line of orbital plate and anterior cranial fossa, the angle from the line between the above point and attachment point of cribriform plate to horizontal line, the distance from vertical line of orbital plate to attachment point of cribriform plate, were measure respectively.

回顾性分析100例患者200侧的鼻窦CT,在冠状位上测量眶板垂直切线与前颅底交点,此点与中鼻甲骨质筛板附着点的连线与水平线的夹角、眶板垂直切线与中鼻甲骨质筛板附着点之间的水平距离。

When the multilayered media contain fluids, the dispersion curves assume the zero mode curve which is inexistent in solid multilayered media. The zero mode curves can be regard as a sign of the existence of fluid interlayer in multichannel analysis of surface waves.

根据文中对4个理论模型的模拟结果来看,与固体层状介质的情况相比,当存在流体夹层时,瑞利波频散曲线模式中多出了一个文中定义的0阶模式,在今后的多道瞬态瑞利波法应用中,应该可以将其看成是流体介质夹层存在的标志性曲线。

Meanwhile the SHRIMP zircon U-Pb age of the fine-grained monzonitic granite is (131.4±1.6) Ma. These precise dating results represent the ore-forming period of this molybdenum deposit, the main dominant geological events and suggest its close relationship with buried Yanshan fine-grained monzonitic granite.

文章通过采集WZK1钻孔211.2~214 m细脉浸染状矿石的辉钼矿纯样,获得辉钼矿的等时线年龄为(134.1±3.3) Ma,并对比了矿区细粒二长花岗岩的锆石SHRIMP年龄(131.4±1.6) Ma,两者基本一致,表明矿床的形成主要与隐伏的燕山期细粒二长花岗岩有着密切关系。

During the surgery, the lesion was found to be a solid tumor. A surgical wedge biopsy was done and purulent dark yellow fluid was drained from the center of the mass. Histologically, there was a solid pattern of rhabdoid and anaplastic round or oval cells haphazardly arranged with poor differentiation. Immunohistochemical staining was positive for vimentin, a mesenchymal marker; the reticulin staining was consistent with carcinoma.

我们实施了手术切片及肿瘤中心脓状物引流,病理组织学上,我们发现了不规则或未分化的横纹状、圆形及椭圆形细胞;免疫组织染色上,细胞广泛的对非上皮标记vimentin呈阳性反应、且其reticulin染色呈现出腺癌的形式;肉瘤及腺癌的特色皆可在切片中看到,所以我们的诊断是类肉瘤性线癌。

The suspicion of cancer is increased by the following factors:(1) age (young patients are more susceptible);(2) sex, if the patient is a man (more women have thyroid cancer by a ratio of 2:1, but women have more thyroid disease by a ratio of about 8:1; thus, a man with a nodule should be regarded with greater suspicion);(3) a solitary nodule (multinodular lesions are usually benign unless there is a dominant cold nodule by thyroid scan);(4) a cold nodule on thyroid isotopic scanning (hot nodules are seldom cancerous);(5) a history of radiation exposure to the head, neck, or chest, especially in infancy and childhood (eg, for an enlarged thymus or enlarged tonsils, acne, or lymphoma);(6) radiographic evidence of fine, stippled psammomatous calcification or dense, homogeneous calcification;(7) recent or rapid enlargement; and (8) stony-hard consistency.

下列因素可增加癌的可疑性:(1)年龄;(2)性别,如果病人为男性(女性与男性的甲状腺癌比为2:1,但女性更多的是得甲状腺病,约为8:1,因此,男性有甲状腺结节时应考虑癌的可能性更大);(3)孤立小结(多结节病变一般为良性,除非甲状腺扫描时呈明显的冷结节);(4)甲状腺同位素扫描时发现冷结节;(5)有过头、颈、胸放射接触史,尤其是婴儿和儿童期(例如,因胸腺增大或扁桃体肿大、痤疮或淋巴瘤等);(6)X线片见细、斑点状、沙粒样钙化或致密、匀质钙化;(7)最近增大或快速增大;(8)质地石头样坚硬。
