成骨

Objective: To study the effects of epimedium pubescens icariine on the proliferation and differentiation of human osteoblasts.

中文摘要：目的：观察淫羊藿苷对人成骨细胞增殖和分化的影响。

MTT assay was employed to examine the proliferation of osteoblasts after treatment with Epimedium.

目的：观察淫羊藿提取液对体外培养的小鼠成骨细胞增殖、功能及凋亡的影响。

In addition, it could be shown that osteoblasts proliferated, differentiated, and produced new mineralized extracellular matrix.

同时，它又能表明成骨细胞能够增殖，分化，并产生新的矿化细胞外基质。

RESULTS: Distraction osteogenesis implants contained intraoral or extraoral distraction device, which could be used for distraction of transport plate.

结果：牵张成骨植入物分为口内牵张器和口外牵张器，可进行转移盘的牵引。

METHODS: The 8 patients underwent mandibular distraction osteogenesis,and altogether 16 distractors were placed through extraoral or intraoral incisions for bilateral distraction. The distraction device proceeded at the rate of 1 to 1.5 mm per day and consolidated for 4 to 12 weeks.

8例患者均行牵引成骨技术牵引双侧下颌骨治疗，经口内或口外途径共安放16个牵引器，牵引速度1～1.5 mm/d，固定4～12周，随访2～18个月。

Extraperiosteal ossification of bone injury induced by fluoride is closely associated with fibroblasts which belong to inducible osteogenic precursor cell in bone, they have osteogenic function under special conditions.

氟性骨损伤骨周化骨与成纤维细胞密切相关，在骨周组织中，成纤维细胞(fibroblast， FB)属于诱导性骨祖细胞范畴(inducible osteogenic precursor cell， IOPC)，在特殊条件下具有成骨功能。

MSC has multipotential that it can differentiate into fibroblastic, osteogenic, adipocytic, and other cell lines.

MSC具有向多种组织细胞方向分化的潜能，如何诱导其向成骨细胞转化是本研究的关键。

All the muscles rebuilt to stable structure after accomplish of distraction, which may help the post-operative stability.2. The changes of myosin heavy-chain mRNA in muscles of mastication during distraction osteogenesis of mandible in canineThe mRNA of MHCI, MHCH and GAPDH in masseter and geniohyoid were measured by RT-PCR.

试验二犬下颌骨牵张成骨过程中咀嚼肌肌球蛋白重链亚型mRNA含量的变化将所取标本应用RT－PCR对嚼肌与颌舌骨肌肌球蛋白重链的两个亚型，即MHCI与MHCll与内参照GAPDH的InRNA进行半定量检测并进行统计学分析。

By means of cephalometric analysis and computeraid operative simulation, the best surgical proposal were gained. Results 15 cases were treated by TMJ reconstruction、 Jaw advancement by transplanted with bone graft and ramus sagital osteotomy, and genioplasty, 3 of the cases treated secondarily by Le fort I osteotomy.

采用电脑辅助的诊断和手术模拟及预测系统，获得充分扩展口咽和纠正颌面畸形的最佳手术方案，以TMJ重建、牵引成骨和正颌外科方法治疗患者。

Cases underwent bilateral TMJ reconstruction, bone graft and genioplasty in order to advance the jaw. Bimaxillary surgical procedure was completed in 3 cases, and distraction osteogensis and TMJ reconstruction in 6 cases. Al patients gained good appearance, 29 patients can open their mouth larger than 3 cm, and one case had recurrent TMJ ankylosis. 29 cases'AI＜5 and oxygen saturation degree ＞90%(included the patient that had recurrent TMJ ankylosis).

结果 本研究有15例患者接受患侧下颌升支倒置TMJ重建、植骨前移，健侧升支矢状劈开、下颌前移和颏前移成形术；其中有3例行二期的上颌的Le Fort Ⅰ截骨术。6例行双侧TMJ重建、植骨前移下颌和颏成形术。3例施行同期双颌截骨前移和颏成形术；6例行单或双侧TMJ重建、牵引成骨术。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
