后侧片

The sample comprised 25 patients with the first premolar removed during orthodontic treatment. Digital models and lateral cephalometric records were taken pre- and post- treatment. We chose two kinds of regional superimposition methods on the digital models (One was the mesial zone of the third primary ruga and regional palatal vault, the other was the palate) and Baumrind's best-fit for cephalometric superimposition. The amounts of incisor and molar movement were measured and a comparative study was performed.

三。选择25例拔除上颌第一双尖牙正畸患者治疗前、后的上颌模型进行三维重建，分别使用第三腭皱近心端局部腭穹隆和腭部对同一患者治疗前、后的数字化模型进行局域重叠，以治疗前后头颅侧位片的 best-fit重叠为评价标准，比较三种方法之间的差异，对应用三维数字化牙颌模型纵向重叠评价正畸治疗前、后的牙齿移动进行探索性研究。

After treated the spinal cord slice at E18 ~ P0 with ChABC at a final concentration of 0.1 U/ml, CGRP-LI fibers in the superficial layers of DH and their branches were seen to extend ventrally instead. When the concentration of ChABC increased to 0.5 U/ml, the above changes were more obvious.

2用0.1 U/ml终浓度的ChABC处理E18 ~ P0的小鼠脊髓片后，原本由DH浅层外侧部向腹内侧延伸的CGRP-LI轴突转为向腹外侧延伸，由DH浅层内侧部向腹外侧延伸的轴突同原本向背侧延伸的分支一起变为向腹侧生长。

The aim of this radiographic study was to visualize the femoral insertion sites of the anteromedial and posterolateral bundle of the anterior cruciate ligament on lateral radiographs in different angles of knee flexion to gain better understanding for arthroscopic femoral tunnel placement in ACL double bundle reconstruction.

此摄片研究的目的是从侧位 X 线片上评价在膝关节不同屈曲角度的情况下前交叉韧带的前内束和后外束的股骨附着点的情况。

Methods Models, posterioanterior and lateral cephalometric films of 90 adults with normal occlusion in Shanghai area were measured and analyzed.

对90名上海地区正常成人牙颌模型、X线头颅后前位片和侧位片进行线距测量分析。

To measure the changes of latera and posteroanterior cephalometric analysis and the changes of casts, before and after treatment with rapid maxillary expansion.

应用RME治疗，测量扩弓前后及治疗结束后头颅定位正位片、侧位片及模型测量方面的变化。

The gross anatomy, histologic description of palmar and dorsal radiocarpal ligament,and its biomechanics properties were studied by applying fresh-frozen and formalin-dip in cadaveric hand-wrist-forearm specimens. 2.An experiment model of unstable distal radius fracture was made by a dorsally based wedge osteotomy used to stimulate a Frykman I distal radius fracture.

通过制作桡骨远端骨折Frykman Ⅰ型不稳定骨折模型，应用压力敏感测试片测试桡骨远端关节面掌倾角变化、以及桡腕掌背侧韧带切断后桡腕关节面的生物力学变化；同时对腕关节进行X线摄片，测量腕不稳发生情况。

The results of Pancherz analysis shows that the correction of negative overjet is mainly due to the advancement of maxilla and upper incisors. But the position changes of mandible and lower incisors imply that severe maxillary hypoplasia with high angle and/or mandibular retrusion is contraindicated by the method conducted in this study.

头影测量侧位片Pancherz分析法的分析结果表明，本研究中上颌后缩患者反覆盖的矫治主要由上颌骨、上切牙的前移引起的，但下颌骨和下切牙位置的变化提示适应症的选择应注意避免上颌后缩同时伴有高下颌角和／或下颌后缩的患者。

Results: Follow-up ob servation of living cells revealed that upon the Ti disc there were cells migra ting from the cellular layer and attaching to the rim of it, forming cells bridg es between them, and then more cells were found to attach and orient as the cult ure went on.

结果：活细胞跟踪观察揭示钛片放入细胞层表面后即有细胞自细胞层表面向钛片侧壁移行、贴附，并在二者之间形成细胞桥。
