骨小体

Methods: Three-dimensional finite element was adopted to compare stress and displacement on osteotome-bone interface at the different shapes of top osteotomes top at osteotome sinus floor elevation.

Summers提出的"骨挤压上颌窦提升术"(osteo-tome sinus floor elevation，OSFE)，由于手术创伤小，术后反应轻，患者易于接受，已逐渐地被临床应用于上颌后牙缺失的种植体植入术中[1~5]。

Results:Plaque index and probing depth in one year after rehabilitation were lower than those in base line. The proportion of spirochetes in subgingival plaque was low (0.21％～ 2.43％) and in the normal level.The mean bone loss was 0.29 mm.None of the implants showed suppuration or mobility.

结果：修复后1年时菌斑指数（plaque index，PLI、探诊深度(probing depth，PD)明显低于基线水平，龈下菌斑中螺旋体比例(propotion of spirochetes，S％)很小(0.21％～2.43％)，总体上处于健康水平，平均骨丧失0.29mm，所有种植体无松动、溢浓。

Symptoms of cemented femoral prostheses the same as the uncemented femoral prostheses were present in male patients at 60-70 years and in female patients older than 55 years old.

骨水泥型股骨假体上的整体应力在男性60~70岁年龄段分布相对较均匀，初始微动变化较小；在女性55岁后分布相对较均匀，初始微动变化较小。

STUDY DESIGN: Retrospective study of posterior hemivertebra resection and osteotomies with transpedicular instrumentation in very young children.

研究设计：对行后路半椎体切除、截骨和经椎弓根内固定年龄非常小的病人进行回顾性研究。

Matsuyama et al used calcium phosphate cement, which polymerizes at lower temperatures.37,38 Results were good in terms of pain relief (8.6 preoperatively and 2 postoperatively on the visual analog scale), neurologic recovery and kyphosis restoration (vertebral height was restored to 68%, compared to 41% preoperatively).37,38 This combination of maximal/minimal surgical treatment has value especially in neurologically compromised patients with indication for surgery, who cannot tolerate long procedures and large blood loss due to medical comorbidities.

Matsuyama等人使用磷酸钙骨水泥，其硬化反应温度较低[37，38]，结果表明疼痛缓解良好（视觉模拟评分从术前的8.6分减至术后的2分），神经功能恢复和后凸畸形矫正良好（椎体高度从术前的41％恢复至术后的68 ％）[37，38]，这个&最大/最小&的手术组合治疗方法，尤其适合伴有神经症状而不能耐受长时间的手术和大量失血的患者。

I assessed if mating common eastern froglets Crinia signifera exhibited size-related patterns. I compared the snout-urostyle lengths and body condition of amplexing males with that of non-amplexing males to determine if successful males were larger or in better condition. I assessed if there was a linear relationship between the body length of the female and the successful male and the relative condition of the male (measured by body mass versus length).

通过比较抱对和非抱对普通东方小蛙的吻-尾干骨长和检测个体较大或状态较好的雄体是否为成功繁殖个体，检测雌蛙体长与交配成功的雄蛙的体长和相对状态之间是否存在线形关系，评估交配与个体大小之间的关系。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
