The underlying cause of bone defects was fracture collapse and reduction in 63 cases, osteomyelitis in 20 cases, bone cyst in 6 cases, fibrous dysplasia in 4 cases and enchondroma in 1 case.

对象：骨缺损患者94例，其中骨折塌陷复位后骨缺损63例，骨髓炎20例，骨囊肿6例，骨纤维异常增殖症4例，内生软骨瘤1例。

There were 12 cases of non-ossifying fibroma, 8 of bone cyst, 7 of osteoid osteoma and 5 of fibrous dysplasia.

病程3～ 18 个月。其中非骨化性纤维瘤12 例，骨囊肿8 例，骨样骨瘤7 例，骨纤维异样增殖症5 例。

The cause and attribution of non-ossifying fibroma remain controversial. It may be a benign bone tumor originated from the osteofibrous.

该瘤的病因和本质尚不明确，从病理组织学、临床过程和生物学行为特点来看，应视为骨纤维细胞来源的良性肿瘤。

Methods From December 2004 to May 2005, 9 cases of bone defectwere repaired with Osteoset pellets; bone defect was caused by benign tumor inlimbs, including 3 cases of fibroma xanthomas in humerus(1 case) and acetabulum (2 cases), 2 cases of bone cysts in humerus(1) and radius(1), 1 case of nonossifying fibroma, 1 case of ossifying fibroma and 2 cases of osteofibrous dysplasia in femurs.

2004年12月～2005年5月，采用Osteoset颗粒作为骨移植材料治疗9例四肢良性肿瘤性骨缺损，其中肱骨黄色纤维瘤1例，髋臼黄色纤维瘤2例，肱骨骨囊肿1例，桡骨骨囊肿1例，股骨非骨化性纤维瘤1例，股骨骨化性纤维瘤1例，股骨骨纤维结构不良2例。

When Fas and c-myc protein were coexpressed in cytoplasm, a strong positive sign appeared in highly differentiated osteosarcoma, fibrous dysplasia of bone and osteoplast of bone callus, a weak sign was found in low-differentiated tumour cells and fibroblasts.

Fas和c-myc蛋白胞浆内阳性，在骨肉瘤的高分化细胞(骨母细胞型和软骨细胞型瘤细胞)和骨化性纤维瘤、骨纤维结构不良、骨痂组织中骨母细胞呈强表达；而在低分化瘤细胞和纤维母细胞则呈弱表达。

Objective:To explore the clinical and pathological dignosis of fibrous dysplasia of bone and ossifying fibroma for improving the dignsis accuracy.

骨纤维结构不良、骨化性纤维瘤两种病的发病部位和组织结构均有相似之处，前者属骨发育异常瘤样病变 [1] 。

Results:The positive expression of P53 and c－Myc protein in nuclei was bound up with poor-differentiated tumours;the positive expression of Fas and c－Myc protein in cytoplasms was consistent with well-differentiated tumours.

采用免疫组织化学方法对骨肉瘤、骨化性纤维瘤、骨纤维结构不良和正常骨痂组织进行c－Myc、Fas和P53蛋白测定，与肿瘤组织学分级、细胞分化及核丝分裂比较分析。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
