骨化的

According to results of animal experiments and review of articles,here the paper discussed the modes of distraction osteogenesis.

在此，根据多年来的动物实验结果以及文献的检索，就有关延伸骨痂的骨化模式的问题加以探讨。

In moderate to severe disease, conventional radiography may reveal tracheal scalloping and nodular irregularity or irregular asymmetric stenosis (Fig 10a). Thickened tracheal cartilage with irregular calcification is seen with CT (Fig 10b).

中到重度的病变，常规X光片可显示气管扇贝状、结节状不规整或不规则、不对称狭窄，CT可见气管软骨增厚并不规则钙化，并有或无钙化的多发结节可以突入气道，气管支气管骨化症的结节不侵犯气管后壁。

In moderate to severe disease, conventional radiography may reveal tracheal scalloping and nodular irregularity or irregular asymmetric stenosis (Fig 10a). Thickened tracheal cartilage with irregular calcification is seen with CT (Fig 10b). Multiple nodules, with or without calcification, may project into the airway lumen.

Meanwhile, the expression of type II collagen, the important marker for chondrogenesis of MPCs, was found in cells treated only with DEX/ TGF-β1 but not cells treated with osteogenic factor or control group.

同时，另一个重要的间叶前驱细胞软骨化表现蛋白第二型胶原蛋白，只有在肾上腺皮质酮跟转形成长因子持续处理的组别中表现，而在其他处理的组别都没有表现。

Well, the incidences of vessel and nerve related variations are higher in ancient Northern Asian group, but the frequency of hypostatic variations and hyperostotic variations made the major contributions to differentiate populations.

北亚谱系古代组中那些与血管和神经相关的变异的出现率都很高，而与骨化不全相关的性状出现率比较低。

The manifestation of clinical and MR Imaging in myositis ossificans have some extent characteristics.

骨化性肌炎临床上多有外伤史，MRI表现具有一定的特征性，提高对其MR表现的认识有助于诊断和鉴别诊断，避免不必要的手术。

Abstract］ objective to discuss radiological findings of parosteal osteosarcoma on emphasis combined with clinical pathology and literature.methods 4 cases of parosteal osteosarcoma proved by operation and pathology were analyzed retrospectively.results female was 3 cases,male was 1 case,average age was 30.5 years old,these tumors were arised on posterior border of distal femur and popliteal cavity,presented as lobular dense ossified mass,defined lesion.one case had villose margin.a thin narrow lucent zone separated the mass from the cortex at two cases.one case underwent angiography,there was no malignant feature.conclusion parosteal osteosarcoma may be divided into low-grade type and high-grade type.radiological manifestations of early stage possess character,early diagnosis conduces to establish rational treating plan and evaluate prognosis.

目的 结合临床病理学特征和文献资料，重点讨论皮质旁骨肉瘤的x线特征。方法收集经手术、病理证实的皮质旁骨肉瘤病例4例，对其进行回顾性分析。结果 4例患者女3例，男1例，平均年龄30.5岁，肿瘤均发生于股骨远端后侧和腘窝处，表现为分叶状致密骨化肿块，边界清晰，其中1例边缘呈绒毛状改变，2例有细窄透亮带与骨皮质相隔，1例行血管造影，未见血管池等恶性征象。结论皮质旁骨肉瘤分为低度恶性和高度恶性两种，早期影像学表现有特征性，早期诊断有助于制订相应的治疗方案和评估预后。

Radiographically, it is difficult to distinguish from long bone fibrous dysplasia, this need the help of pathology.

但对於复发的病例，病灶的破坏范围会更大，且有不等程度的反应性骨化及骨膜增生。

To measure the anterior-posterior proportion of ossified mass or degenertive apophyses and bulge of disc to spinal canal in CT myelography before operation,to record the minimum AP diameter of spinal cord.

根据术前CTM片测量OPLL骨化块及退变性软硬突（椎体后缘增生的骨质或突出的椎间盘）各自占据椎管前后径的比例，并记录颈脊髓最小前后径。

At the same time there are more than 100,000 pieces of stone, the bulk of the bone, fossils of more than 100 kinds of wild animals, there are a lot of ashes, in which the fossil animal bones in addition to the rhino, antelope, spotted deer, ox, tiger, leopard, wolf, there are has been extinct saber-toothed tiger, deer, such as swelling of bone.

同时还有10万多件石器，成批的骨器，100多种野兽化石，还有大量的灰烬，其中兽骨化石除了犀牛、羚羊、斑鹿、牛、虎、豹、狼外，还有已经灭绝了的剑齿虎、肿骨鹿等。
