The fundamental imaging features of osteosarcoma were showed bone destruction, periosteal reaction, neoplastic bone and soft-tissue mass. Among 49 cases examined by radiography, osteoblastic pattern sarcoma was found in 19 cases, osteolytic pattern sarcoma was found in 13 cases and mixed pattern sarcoma was found in 17 cases. The detection rates of bone destruction, periosteal reaction, soft-tissue mass, neoplastic bone and Codman triangle by radiography were respectively 61.2%, 95.9%, 71.4%, 73.5%and 27.7%. All 10 cases with CT scan were showed bone destruction, soft - tissue mass and neoplastic bone. The detection rates of periosteal reaction,憇ieve sign挶 and Codman triangle with CT scan were respectively 90%, 90% and 11%. The tiny neoplastic bone and"sieve sign"were showed sensitively by CT, but Codman triangle was showed by radiography superior to CT.32 cases with MRI scan presented the normal marrow was replaced by the tumor, which was showed low to intermediate signal intensity on T1-weighted images and promiscuity signal intensity on T2-weighted images. 7 cases presented hemorrhage and 24 cases presented necrosis.

Breast cancer commonly metastasizes to bones, producing both osteolytic and osteoblastic deposits. Different markers for quantitative determination of bone turnover have been developed to evaluate bone metastases of breast cancer. The urinary deoxypyridionline, a crosslink product of collagen molecules found in bone and excreted in urine during bone degradation, and bone specific alkaline phosphatase, an isoenzyme localized in the membrane of osteoblasts and released in circulation during bone formation, were recently described as a group of markers of bone turnover in metastatic cancer.

乳癌患者常见骨髓转移造成溶骨性及成骨性沈积物，而利用不同标记来定量骨质转换形态，可以评估乳癌骨骼转移的变化，而尿液中Deoxypyridinoline是骨质内胶原分子在骨骼破坏分解时至尿中的产物，骨特殊碱性磷酸酵素是一种同形酵素，位於成骨细胞的外膜且在骨骼形成时释放至血液中，利用此两种生化标记，可以来预测乳癌转移至骨骼的转换情形。

In the second part of this thesis. The biological process of porons HA/bBMP composite repairing experimental defect in the dog femora and monkey mandibular were investigated by the qualitative and quantitative methods. The results showed that not only were the speed and time of new bone ingrowing into the bBMP/HA composite much quicker and earlier than that of implants of HA alone, but also the quantity of new bone ingrowth into bBMP/HA composite was much higher than that of HA alone. The bone ingrowth of bBMP/HA composite at higher rate within 3 weeks. In this study, bBMP/HA promoted more active new bone formation in bone marrow tissue than did HA alone. This reveals that BMP, brought into the bone marrow with HA as a carrier, accelerates osteogenesis or osteoinduction, providing sime bone marrow cells with more differentiative potential.

论文第二部分应用定性和定量的方法，较全面地研究了HA/bBMP复合人工骨在修复狗股骨和猴下颌骨实验性缺损中的生物学过程，研究发现，新骨组织长入HA/bBMP复合人工骨的时间和速度都较单纯HA早和快，而且新骨形成量也明显高于单纯HA，HA/bBMP在挂入后早期(3周)的成骨最为活跃，自体骨髓组织可为BMP提供敏感的靶细胞，增强BMP的骨诱导效果和HA/bBMP复合人工骨的骨修复能力。
