To evaluate the role of collagen Ⅰ,Ⅲ and Ⅳ in the formation of the pericystic layer of hepatic hydatid cyst The expression of collagen Ⅰ,Ⅲ and Ⅳ in pericystic layers of hepatic hydatid cysts from 40 patients was observed using immunohistochemical methods.

探讨Ⅰ、Ⅲ和Ⅳ型胶原在形成肝包虫囊肿周围人体纤维囊壁中的作用及其临床意义。采用免疫组织化学方法检测Ⅰ、Ⅲ和Ⅳ型胶原在40例肝包虫囊肿周围纤维囊壁中表达。Ⅰ、Ⅲ和Ⅳ型胶原在肝包虫囊肿周围纤维囊壁中出现特异性分层表达。

The source of the energy for both protoplasmic streaming and migration of the chromatin substance is supplied by ATP which is produced in the process of aerobic respiration.

为了进一步证实假说的可靠性，同时，为了弄清染色质穿壁的途径，穿壁后染色质的命运以及核骨架、细胞骨架与染色质穿壁运动的关系，我们以百合为材料。

Result 20 cases of normal photographs showed that media orbit wall shape and thickness were irregular,media orbit wall was closely related to media rectus muscle in anatomy,structural relationship in orbit was obvious,and the vertical distance between external orbit rim and cornea top was ocular protrusile degress.8 cases of abnormal photographs showed some features including high myopia in 4 cases,eye injury in 3 cases,and media orbit wall deformity in one case .

结果 20例正常CT片显示眶内侧壁形态和厚度不规则，在解剖上眶内侧壁和内直肌密切相关，眶内结构关系明显，2侧眶外缘和角膜顶点垂直距离为眼球突度。8例异常CT片显示特征包括高度近视4例，眼外伤3例，眶内侧壁畸形1例。

The Lithostegia Ching was considered as a member of Peranemaceae for a long time, according to the research,we found that it has the typical scalariform perforation plates,no associated or crossed phenomena,and some region have intact plate,no dimorphic phenomena,no weblike or threadlike remnants,these suggest that The Lithostegia Ching is in a primal evolutional position.

与传统观点不同，我们认为穿孔板仅存在于端壁的管状分子为导管分子，而端壁和侧壁形态、结构相似，有或无穿孔板的管状分子为管胞，蕨类植物中的管状分子主要为管胞。

This can be kind hard to do when the draws are resting on slabby stuff, as the rope is interfered with by the rock. It has a distinct advantage that you can easily "grab" the draw if you start to slip, and that you can use the pull on the draw to bring up slack out of the rope.

这在斜板地形较不顺手，因为快扣靠在岩壁，绳子会被岩壁妨碍到；不过，好处是当你有点要滑动时可以&抓住&快扣，且顺势带出贴紧岩壁的绳子。

Results:77.5% of sphenoid ostia can be identified by endoscope directly.The distances from sphenoid ostia to the superior and lateral wall of sphenoid sinus,the foramen of sphenopalatine artery,the anterior wall of sella,posterior nasal septum and nasal column were 9.6±4.1 mm,9.2±1.8 mm,11.1±1.6 mm,14.7±3.6 mm,3.6±0.5 mm and 61.6±3.7 mm respectively.

结果：77.5%的蝶窦口内窥镜直接窥见，窦口距离蝶窦顶壁、外壁、蝶腭动脉孔、鞍前壁、鼻中隔后端分别为8.6±3.1 mm、9.2±1.8 mm、11.1±1.6 mm、14.7±3.6 mm、3.6±0.5 mm，距离鼻小柱根部前缘61.6±3.7 mm，与鼻底夹角31.8°±5.2°。

Objective This study evaluated clinical value of inferior ST segment depression in acute transmural anterior myocardial infarction.

目的探讨急性前壁透壁性心肌梗死时下壁导联ST段压低的临床价值。

ST depression in transmural ischaemia was generated with ST elevation and was an integral part of the current source.

利用心肌的双域模型计算机模拟了不同区域心肌透壁缺血时ST 段位移在心脏表面的分布，发现心脏表面ST 段位移的分布式样和缺血区域大小有关，一个小面积的透壁缺血在缺血区上出现均匀分布的ST 段上升，而在心脏表面的其他部位上几乎没有出现ST 段下降；一个大面积的缺血像左降支或左旋支区域的缺血， ST 段位移在心脏表面的左侧区出现了一个偶极子式的分布，在缺血区为ST 段上升，在正常区为ST 段下降，并且其幅度随远离缺血边界而减小；同时发现透壁缺血时的ST 段下降是缺血电流源的不可分割的一部分。

The distribution of those abnormal expressions mentioned above tended to be extensive and homogenous in unruptured aneurysms, while localized in ruptured ones.

以上异常表达在囊性动脉瘤壁中的炎性反应区较为明显。在破裂动脉瘤的瘤壁中趋于局部集中表达，而在未破裂动脉瘤的瘤壁中分布较为均匀。

The flowfield and performance of a centrifugal compressor was predicted and analysed, which was composed of a Krain's impeller and two types of vaneless diffuser specially: one was constant area vaneless diffuser and the other was the straight-wall. The results show that the efficiency of the straight-wall vaneless diffuser is obviously lower than that of the constant area, and a separate flow occurs nearby the exit of the centrifugal impeller with the straight-wall diffuser. However, the type of vaneless diffuser has little influence on the aerodynamics performance of the centrifugal impeller. Finally, it is suggested that the constant-area vaneless diffuser should be selected as the downstream extended area of the centrifugal impeller during the prediction for the centrifugal impeller.

对Krain叶轮后带等面积与直壁两种形式的无叶扩压器离心压缩机内部流场进行了计算与分析，结果表明：直壁型无叶扩压器离心压缩机的效率低于等面积无叶扩压器离心压缩机的效率；直壁型无叶扩压器使得叶轮出口的流动出现分离；扩压器的形式对离心叶轮的整体气动性能影响并不大；在进行离心叶轮数值研究时，叶轮后的延伸区最好采用等面积无叶扩压器，以尽量减小无叶扩压器所引起的计算误差。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
