Nowadays, bone defect has become one of the most important disease which threat people's living quality severely. Today, the most common methods used to healing bone defects include: Autogenous bone grafts and allogenic bone grafts. But autogenous bone grafts have a shortage on donor, difficult to make shape and will bring a complicate disease on donor site; allogenic bone grafts often follow with graft rejective reaction, and have a potential risk of propagation of many disease.

目前，主要应用于临床骨缺损修复的方法有自体骨移植和异体骨移植等，但自体骨移植存在材料来源有限、供骨部位的损伤以及塑形困难等问题；异体骨移植也有潜在的疾病传播隐患以及移植排斥反应等严重后果，因此无论自体骨移植还是异体骨移植均无法完全满足需求，临床急需寻找一种安全有效的骨移植替代材料。

Methods Fifty healthy SD rats were fed for twentytwo months in order to build the model of aging rats, the histology of femoral bone, tibial bone and lumbal vertebra was used to observe, then we evaluated the indexes which reflect the degeneration of intervertebral disc including the quantity of collagen type Ⅱ,Ⅹ of intervertebral disc by the immunohistochemistry methods, the relative area of vascular bud, the thickness of calcified layer and uncalcified layer on cartilage endplate and the indexes which reflect the osteoporosis including the thickness ratio of cortical bone, the relative area of bone trabecula, the bone density, the max stress and straining of bone.

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。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.
