Methods BMSCs isolated from rabbit iliac bone marrow were culture-expanded in vitro. The injectable tissue-engineered bone constructed from autologous PRP, FG, and BMSCs was cultured in vitro, and its biological characteristics were observed including the time of gel formation, histological features, seed cell survival and microscopic structures. Results The constructed injectable tissue-engineered bone began gel formation within 20 to 30 s, and after a week-long culture, the gelatine began to degrade, and numerous well viable fusiform cells could be seen to adhere to the bottom of the Petil dish, Scanning electron microscopy identified globular and olivary cells embedded in the fibrin glue, and numerous small particles could be seen around of the cells.

从兔髂骨处抽取骨髓体外培养BMSCs并诱导向成骨细胞分化，抽取兔自体动脉血提取PRP，以FG、BMSCs、PRP共同构建可注射型组织下程骨并体外培养观察其生物学特性如凝胶形成时间，组织学特点、细胞存活情况及其超微结构特征等结果构建的可注射型组织工程骨可在短时间内形成凝胶，体外培养1周时其中细胞生长良好，电镜下见纤维蛋白网格结构致密，种子细胞及血小板颗粒分布广泛。

方法］24例长骨骨折内固定手术失败应用有限切开交锁髓内钉治疗的长骨骨折翻修术病例中，股骨15例，其中股骨干骨折14例，股骨髁上骨折1例；男11例，女4例；左侧7例，右侧8例；接骨板螺丝钉折弯1例，断裂6例，普通髓内钉折弯1例，折断2例，螺钉并钢丝固定假关节形成1例，骨折不愈合4例。

Methods 46 clinical cases were the patients in our hospital who had cranial trauma to have operation. The lesions were located on frontal, temporal and junctional areas. The coronal incision, enlarged pterion and standard large cranial flap approach were adopted to decompress by removing cranial flap, hematoma or cerebral tissues. The dura mater was mended by the deep temporal fascia with pedicle and subgaleal tissues.

我院收治的颅脑损伤手术患者46例，病灶主要位于额颞部或交界处，采用冠状切口、扩大翼点入路或标准大骨瓣减压入路，进行去骨瓣减压、血肿清除或内减压手术，硬脑膜用带蒂颞深筋膜与帽状腱膜下组织进行修补。

The edgewise technique was used to align and level the upper and lower arches gradually and upright the lower incisors. Then, modified LeFort Ⅰ osteotomy was operated with 4 cases pterygomaxillary disjunction and the other 2 cases not. The maxillas were not moved during the operation and sutured mucoperiosteum at the same place. After 3-5 days latency period, elastic distraction about 700g/side and increasing to 1400g/side gradually, was started with two cases which the maxillas were not cut off totally.

术后经过3—5天的延迟期即开始牵引，2例行不完全截开术者，采用弹性牵引，力量从700g／侧逐渐增加至1500g／侧；4例行完全骨截开术者，首先采用刚性牵引和口外牵引钩，每天缩短牵引钢丝1mm，2例直接达到矫治要求，其余2例达到浅覆盖后，截去口外牵引钩，换弹性牵引和口内牵引钩继续前牵上颌骨。
