From 2004 to 2007, 34 cases were treated with extrapedicular screw fixation in Department of Orthopaedics, Third Affiliated Hospital of Sun Yat-sen University. The screw entry point, angle, depth and diameter were measured and defined on the thoracic vertebrae pedicle by CT thin-slice scan in standard prone for all cases before operation. The screw entry point was located at the tip of transverse process. The average inclination angle should be 10°-20° headward and 30°-40° toward neutral line respectively. The screw was inserted and entered into the vertebral body along the external cortex of pedicle. The integrity of cortical bone around screws, the distance to segmental blood vessels and the penetration of cortex were observed after operation to evaluate the accuracy and safety of screw placement.

应用椎弓根外内固定技术2004/2007年在中山大学附属第三医院骨科治疗34例患者，固定前采用CT加密扫描测量进钉点、进钉点至椎体前缘的深度、进钉角度和直径，固定中椎弓根钉入点为横突尖，进钉方向为平均向头侧倾斜10°~20°、与中线成角30°~40°，顺椎弓根外侧皮质进入椎体，固定后CT加密扫描观察螺钉周围的皮质骨是否完整、是否靠近节段血管、是否穿透皮质骨，评价置入钉的准确性和安全性。34例患者共置入160枚胸椎椎弓根螺钉，固定后CT加密扫描和X射线片观察到148枚(92.5%)螺钉置入准确，12枚(7.5%)螺钉发生错置。

Methods The imaging features of nine patients who refused amputation and chose to be treated with Chinese herbal medicine were observed. Of the patients, four were confirmed pathologically, two were found to have pulmonary metastasis at diagnosis, one of femur osteo-genic osteosarcoma with osteogenic metastasis was found in the epiphysis of the homolateral tibia, and the other two were proved to have no possibility of other diseases by radiological specialists to demonstrate the imaging diagnosis of osteosarcoma.

观察拒绝截肢采用中药治愈的9例骨肉瘤影像学表现，其中4例经活检病理证实，2例诊断骨肉瘤时肺部已发现转移，1例股骨成骨型骨肉瘤同侧胫骨骨骺内有成骨性转移，另外2例经影像学专家按举证倒置程序，论证骨肉瘤的影像学诊断，排除了其他病变的可能。

Chenayya saw the woman's eyes grow large with anxiety. To dispel her fear, he grinned ingratiatingly at her—it was the exaggerated death-mask grin of a person not used to grovelling—then he looked around to figure out where he had left the table.

看见恩哲尼尔夫人的眼睛由于恐惧越睁越大，为了缓解她的恐惧，成内亚讨好地对着她露齿一笑——那个笑容夸张地尤如一个死人面部模型上的笑容，而不是讨巧那种，然后环视四周，看看要把柜子放在什么位置。

We describe a case of NLPHL showing a variant histologic pattern characterized by small and large clusters of lymphocyte predominance cells within nodules defined by follicular dendritic cell meshworks, associated with numerous neutrophils and areas of internodular fibrosis. Focally, the neoplastic cells had lacunar cell-like cytologic features.

在此，我们描述一例组织形态特殊的NLPHL，其形态学表现为以淋巴细胞为主的细胞排列成大小不等的结节，结节均由滤泡树突状细胞网网罗，结节内见中性粒细胞浸润，部分结节间见纤维化，局灶瘤细胞呈陷窝样。

Assisted by DNA2.0 and Gene2Oliga software, we optimized the codon usage and secondary structure of RNA and induced enzyme sites Cla I (237 site) and Pst I (475 site) into the gene. In the first step, fragments F1 (237 bp), F2 (238 bp) and F3 (422 bp) were separately synthesized by assembly PCR. In the second step, fragments F1, F2 and F3 were separately digested by Cla I and Pst I, and then ligated into a full length lipA gene.

首先在DNA2.0和Gene2Oliga软件辅助下对lipA基因密码子及RNA二级结构进行优化并引入Cla I(237位)和Pst I(475位)酶切位点；通过组装PCR分别合成lipA基因的各片段F1(237 bp)、F2(238 bp)和F3(422 bp)；通过该基因内的Cla I和Pst I限制性酶切位点连接成完整的全长lipA基因。

In this study we compared the frequency of successful PTN blockat the traditional distal site (2 cm above the medial malleolus)with and without NS guidance.

在这项研究中，作者比较了使用和不使用 NS 向导的情况下，在传统的远中心端（内踝2cm ）成实施 PTN 阻滞的频率。

A Contrast-enhanced CT scan of the upper abdomen shows a saclike mass of dilated jejunal loops between the pancreatic head and stomach. The descending mesocolon and stomach are displaced laterally. The dilated inferior mesenteric vein is located at the anterior border of the encapsulated loops.

a 上腹部增强CT扫描显示胰头和胃之间见囊状成簇扩张的空肠，降结肠系膜和胃被推移到侧方，扩张的肠系膜下静脉是疝囊内肠襻的前界。

A major section of Nar Shaddaa became a refuge for Neimoidians in hiding.

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。
