In this experiment, in the way of observing the histological changes, relative content of myosin heavy-chain mRNA and changes of the expression of IGF-I in masseter and geniohyoid muscle during distraction osteogenesis of canines mandible, we can learn about the rebuilding ability of masticatorymuscles and its changing regularity, and preliminarily discuss its remodeling mechanism.Anteroposterior bilateral distraction osteogenesis was performed on 14 mongrel canines, 6 to 8 months of age, using intraoral mandibular distractor.

本实验通过观察犬下颌骨牵张成骨过程中嚼肌与颏舌骨肌的组织学变化、肌球蛋白重链亚型mRNA含量以及IGF-I在咀嚼肌中表达的变化，了解牵张成骨过程中口颌肌肉的改建能力及其变化规律并初步探讨其改建机制。

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。

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。

Objective to study the changes of endothelin and nitric oxide in gingival tissue of periodontitic patients and their relationship with local bone absorption.

目的 为了探讨慢性牙周炎患者牙龈组织中ET和NO的改变与局部颌骨的吸收及骨质疏松的关系。

He is good at crown beauty teeth, crown fixed teeth, false teeth and micro root canal treatment and laser water treatment and removing teeth and gnathic surgery.

擅长显微根管治疗、水激光牙体治疗及各种复杂牙拔除和颌面外科手术治疗。

By pushing a whole series of branching points in gnathostome evolution out of the Devonian and into the Silurian, the discovery of Guiyu also signals that a significant part of early vertebrate evolution is unknown Fig.

此外，鬼鱼的背鳍棘刺和其前方具有棘刺的骨板很可能也是原始特征。上述特征在早期有颌类中广泛分布，而它们却同时出现鬼鱼身上，使得我们首次观察到了肉鳍鱼类一系列重要鉴别特征的演化顺序。

Hoxall genes from 16 vertebrates were analyzed, containing 10 cloned Hoxall genes mentioned above and 6 Hoxall genes from GenBank, Homo sapiens, Mus musculus, Bos taurus, Polyodon spathula, Heterodontus francisci, and Oryzias latipes, in representatives of the three major gnathostome lineages: cartilaginous fish, ray-finned fish and lobe-finned fish.

克隆的基因与从GenBank中获取的人、小家鼠、黄牛、匙吻白鲟、角虎鲨Hoxa11基因及青鳉Hoxa11a基因进行比较分析，这些动物代表了有颌类的三个谱系：软骨鱼类谱系、辐鳍鱼类谱系(斑马鱼、大黄鱼、花鲈、罗非鱼、红鳍东方鲀、乌鳢、青鳉和匙吻白鲟)和肉鳍鱼类谱系(矛尾鱼、热带爪蟾、绿背树蜥、家鸡、人、小家鼠和黄牛)。

The result of Neighbor-joining molecular phylogenetic tree also indicated that the eggs and the Japanese halfbeak were assembled at the same embranchment, they shared one haplotype, but the eggs were assembled at different embranchments with the other species of Beloniformes so the fish eggs were alienated from them.

NJ分子系统树的聚类结果也显示鱼卵与沙氏下鱵鱼序列聚为一支，他们共享一个单倍型，而与其它颌针鱼目鱼类序列分为两大支，其亲缘关系较远。

The result of genetic analysis conveyed that in partial sequences of mtDNA Cyt b gene there were no variable sites between the eggs and Japanese halfbeak, and the genetic distance between them was 0, however, many variable sites between the eggs and the other fishes of Beloniformes were exised, the variable rate was 18.72-21.3％, and the genetic distance between them were 21.9-26.4％.

遗传学分析结果显示：鱼卵与沙氏下鱵鱼mtDNA Cyt b基因片段序列之间无差异，遗传距离为0，而与其它颌针鱼目鱼类序列间差异达18.72～21.3％，遗传距离在21.9～26.4％之间。

Objective : To explore the methods of orthognathic treatment for hemifacial microsomia.

摘要』目的：探讨治疗半侧颜面发育不全畸形的各种正颌外科与其他手术方法组合，为提高治疗这种畸形的效果提供临床参考。
