小骨的

Presurgical nasal molding produced tissue expansion of the short columella and corrected the nasal tip cartilages. Up to 5 months of active treatment was needed before lip repair.

将前颌骨向后移动，排列在两侧牙槽骨之间，使牙槽骨成为较为规则的弧形排列；鼻软骨塑形及鼻小柱延长。

MAIN OUTCOME MEASURES: Number of trabecular bone closely or not closely connected by bone cement section surrounding to calculate the rate of combination; condition of surfaces of marrow cavity and bone cement in the column by amplifier.

主要观察指标：观察CT片，测出骨水泥截面周围与骨小梁结合紧密者与非结合者的个数，计算结合率。用放大器材观察骨髓腔内表面及骨水泥内柱表面情况。

Results: Compared test group with control group at 14th day of experiment, test group rats were osteoporotic. The lower bone density figures of test group showed that bones were osteoporotic and test group bone HE microtome section showed that bone trabecula was looser, os integumentale was thiner and chondrocyte was decreased.

结果：实验第14天，模型组与对照组相比，模型组大鼠骨质疏松模型建立成功：骨密度不同程度的降低、骨HE切片中骨小梁稀松、皮质骨变薄、软骨细胞层减少等病理变化。

The tumor was excised and was found to be composed of bony trabeculae in a fibrotic stroma with many osteoclasts, a finding consistent with osteitis fibrosa.

切除肿块后发现肿块的成分为骨小梁和纤维化机制，机制中有许多破骨细胞，此发现与纤维性骨炎相符。

Patients were treated by surgery, among them 2 patients died of temporal lobe radionecrosis,and the survival time of re...

CT特征性表现：骨破坏广泛而对称或局限；骨体的表面裸露在气腔中；有死骨形成；软组织内见小气泡。

Mallory trichrism staining exhibited light blue samples. Eight weeks following repair, CT showed round blunt defect edges in the coronal position, which had bony pustute connection with gel materials. Density at the defect region significantly increased. 3D reconstruction suggested that defects became small. After hematoxylin-eosin staining, abundant fibrous connective tissue appeared in defect regions, with bony tissues. Mallory trichrism staining revealed that maroon mature bone tissues were found, surrounded by light blue chondroid tissues. Twelve weeks following repair, coronal defect regions were filled with callus. 3D reconstruction showed that defects were repaired. Defect region and surrounding bony tissues had bony connection, with thick bone trabecula and mature Haversian system.

修复后8周，冠状位CT显示缺损边缘圆钝，与凝胶材料有骨性突起连接，缺损处密度增高明显，三维重建显示缺损范围较之前有所减小；标本苏木精－伊红染色后缺损部可见大量含血管成分的纤维结缔组织，有骨样组织结构形成，Mallory三色染色显示有褐红色成熟骨组织形成，其旁边有淡蓝色软骨样组织修复后12周，冠状位CT显示缺损区基本被骨痂填满，三维重建示缺损基本修复；缺损区域和周围骨组织形成骨性结合，骨小梁粗大，哈弗氏系统成熟。

CT displayed the structure of femoral head was vague. A piece of coloboma could be observed clearly on the cartilage of a femoral head. Medullary canal was almost filled with white adipose tissue. Osteoblasts and osteocytes decreased. Empty bone lacuna increased. Thrombus distributed widely in the bone tissue microcirculation.

MA组病理检查肉眼可见股骨头软骨面局部缺损，坏死面暴露，髓腔内大量脂肪组织堆积；光镜下成骨细胞、骨细胞均减少，空骨陷窝增多，微小血栓广泛分布，变形扩大的脂肪细胞挤压正常骨髓组织细胞，骨小梁变细破裂明显。

Results Intramuscularly injected with hydrochloric dexamethasone for6weeks,the rabbits in osteoporosis model group showed obvious signs of osseous destruction such as destruction in the facies articularis of femur head,rar-efaction and fragmentation of trabecula,disappearance of myeloid cells,while those in control groop showed few sign of osseous destruction.

结果 对实验兔予以肌肉注射DX6周后，正常对照组基本无骨质破坏的征象，而骨质疏松模型组则表现为股骨头关节表面软骨破坏，骨小梁稀疏、断裂，骨母细胞消失等明显骨破坏现象。

At 3 months after operation, there are dense, firmly anchored bone with an haversian architecture at the interface between the hydroxyapatite and the cortical bone.

术后3个月，在涂层与皮质骨相邻处，出现致密、富含哈佛系统的栓状骨组织；在涂层与松质骨相邻处，出现大量新生骨小梁结构。

Osteoporosis is a metabolism disease of micro bone tissue disorganization , bony mineral matter and bony matrix reduce at same rate, sclerotin turn week, trabecula of bone decrease ,which make the brittleness of bone raise and fracture easily.It is common illness and frequently occurring illness in old people ,even in menopause women.

骨质疏松(Osteoporosis，OP)是一种以骨组织显微结构破坏、骨矿成分和骨基质等比例地不断减少，骨质变薄，骨小梁数量减少，导致骨骼脆性增加和易发生骨折的全身代谢障碍性疾病，是老年人的常见病与多发病，尤以绝经妇女为重。
