Methods:The edentulous patients of senile males and postmenopausal females were selected.All the edentulous subjects were divided into two groups according to the degree of RRR of mandibles: well-rounded ridge group and atrophied ridge group; The BMD of mandibular angle and coxofemoral region (femoral neck,trochanter,and wards triangle) of all subjects were measured by dual energy X-ray absorptiometry.The BMD were compared between well-rounded ridge group and atrophied ridge group in the same sex group.

将60岁以上男性和绝经后女性无牙颌患者依据下颌剩余牙槽嵴吸收程度分为丰满组和非丰满组；采用双能X线吸收法，测量全部研究对象右侧髋部与左侧下颌角的骨密度；在同性别组内对比丰满组和非丰满组间下颌角和髋部骨密度的差别。

First 27 rabbits of the experimental group were destabilizated by operated on L6、7.Inj Diazepam 0.25 mg/kg,Inj Ketamine 0.02 g/kg and Inj Atropine 0.125 mg/kg was one by one injected into the rabbit through the auris vein,shearing the rabbit hair of backside waist,fixing the rabbit on operation table in face lying,using 1% Povidone Ioding to degerm the operation area.Every rabbit was incised at the backside of its waist,that incisal opening is located in the center of the intervertebral space (L6、7 space) that both side iliac crest line correspond ,from the meso-ordinate direction cut about 4 cm incision,cutting open skin and subcutaneous tissue,thoroughly ,exposing the spinous processes the vertebral plates and the upper-inferior articular processes,entirely segregating the muscles that cohere the spinous processes the vertebral plates and the articluar process,then excising the supraspinal ligaments and interspinal ligaments,biting off two sides the inferior articular processes of L6,in order that resulting in intervertebral destabilization,using 0.9% Inj.Sodium Chloride to washout the incisal opening,in order sewing up each layer tissues.

方法］ 取48只6个月龄日本大耳白兔，雌雄不限，体重为（2.5±0.2） kg，随机进行分组，分为对照组和实验组，对照组为21只；实验组为27只；先将实验组兔腰背部皮毛剪除，用安定注射液1.25 mg/kg、氯胺酮0.02 g/kg、阿托品0.125 mg/kg顺次耳缘静脉注射麻醉后，俯卧固定于手术台上，用1%碘伏消毒手术区域，以髂嵴平对椎间隙（即L6、7）为中心，从正中取一长约4 cm纵行切口，切开皮肤及皮下组织，锐性分离，暴露棘突、椎板及上下关节突，将附着于棘突、椎板及小关节的肌肉全部分离开，然后依次切除L6、7棘上及棘间韧带，咬除第6腰椎两侧下关节突，造成椎间失稳，用无菌生理盐水冲洗切口，依次缝合各层组织；术后动物在笼中自由活动。

ConclusionOne-stage posterior hemivertebrae and osseous divide resection combined with transpedicular instrumentation and bone graft can achieve a satisfactory result for the treatment of scoliosis of thoracic hemivertebra and diastematomyelia of adolescent.It can be recommended in clinical practice because of a good stability of fixation and fine spinal fusion.

结论一期后路半椎体及骨嵴切除、椎弓根螺钉内固定植骨融合术是治疗青少年胸椎半椎体脊柱侧凸合并脊髓纵裂的有效方法，具有较好植骨融合和稳定性，值得推广应用。

The positive hybridizations with COCH gene cRNA probe were detected in the mouse mesenchymic cell surroundding the endolymphic sac epithelium, the level of expression was similar to the fibrocytes underlying crista ampullaris sense epithellium, and inferior to the fibrocytes of spiral ligament.

成年小鼠内淋巴囊周围间质细胞COCH基因表达阳性，其原位杂交染色平均积分光密度为0.4±0.25（〓±SD，单位：U／mm〓），与壶腹嵴感觉上皮下间质细胞的0.47±0.21相似，弱于耳蜗螺旋韧带成纤维细胞的0.77±0.19。

Tooth is a typical epithelium-mesenchyme organ, which is formed through the mutual function between the original oral epithelium and epiblastic mesenchyme from the neural crest below.

牙齿是典型的上皮-间充质器官，由原口腔上皮和其下方的神经嵴来源的外胚间充质相互作用而形成。

Over time, the iron pigments infiltrate the underlying neural tissue and may in turn result in necrosis of the crest of the cerebellar folia and the vermis.

This evidence suggests that, myf5 is involved in axial and non-axial mesoderm interaction during gastrulation. The disrupted hindbrain segmentation affects the fgf3 signaling, thus causing the CNC to undergo apoptosis.

这些证据显示，myf5在原肠化过程扮演重要角色，Myf5的缺失造成后脑fgf3讯息传递缺失，干扰后脑分节发育，进而影响之后的神经嵴细胞与软骨的发育。

Methods: The distal 1/3 of eighty humeri was scanned by 16 layer spiral CT. The morphologic features of the intramedullary bony prominence above the olecranon fossa were observed and described on coronal, sagittal and transverse section after three-dimensional reconstruction. Then the distal 1/3 of twenty humeri was splitted vertically along the coronal midline for observing the intramedullary bony crista.
