Mandibular advancement in rats caused cellular changes of condyle,which led to increased Flk-1 expression and endochondral ossification.

下颌前伸后大鼠髁突软骨细胞Flk-1表达增强，说明其介导了VEGF引发的软骨内骨化过程。

Methods: 62 cases with anterior deep overbite were treated with a modified appliance which was composed of four parts-the anterior bite plate,the anchorage on the second molars,the rectangular wire with higher elasticity and intermaxilla traction.

该矫治方法由前牙平导板、高弹性方弓丝、第二磨牙设计支抗、后牙颌间垂直牵引等组成。结果：经临床应用2 年，共62 例，效果良好。平均疗程4 个月。

As seen tod ay we still identify quite some of the traces of the traditional model in what are referred as school-based training, mentorship, practice-orientation, unification of pre-service education and in-service education, to mention but a few; while on the other hand, the British practices in school-based teacher training and the monitorial system are seen as representatives of the transcendent characteristics from conventions, and initiated the new perspectives in teacher education for the world to follow.

对传统的珍惜使英国人对已有的习惯具有某种难以舍弃的执拗，以致于在许多国家开始依托师范学校进行师资培养之后的很长一段时期，英国还固守着以&师徒制&为主要方式的教师在职培养，乃至今天英国教师在职教育的许多特点如&校本培训&、&良师制度&、实践取向、职前职后的&一体化&等都可以从早期的&导师制&中寻找到明显的&踪迹&；对传统的超越使英国教师的在职教育在&导生制&和&校本培训&等方面又开创了世界的&先河&。

Methods 203 cleft palate patients(406 ears)were investigated by pure tone audiometry,acoustic immitance audiometry and auditory brainstem response.21 cleft palate patients with SOM underwent palatoplasty and myringotomy with tube insertion at the same time.

方法对 2 0 3(4 0 6耳)例腭裂患者进行年龄分组，采用声导抗，纯音测听或听性脑干反应检查判断中耳功能。2 1例腭裂伴分泌性中耳炎患者在作腭裂修复术的同时，行鼓室置管术，术前术后作听力学检测。

MethodsSodium Hyaluronate was injected into the palatoglossal arch, palatopharyngeal arch and root of the tongue of eight Wistar rats. An electroencephalogram, electromyogram and oronasal airflow were recorded by PSG before and 4 weeks after injection when rats were under light anesthesia, which was expected to be similar to the sleep state.

方法将8只Wistar大鼠的双侧舌腭弓、咽腭弓及舌根处注射透明质酸钠，分别于注射前及注射后4周，以浅状态模拟睡眠状态，用多导睡眠仪监测动物的脑电、肌电及口鼻气流。

By means of acoustic impadance and otoscopic examinations the middle ear function and incidence of secretory otitis media were demonstrated in 43 cases of cleft palate children pre-and post palatal closure.

为研究腭裂修复术对中耳功能的影响，应用声导抗及耳镜检查，以43例腭裂患者于腭裂修复术前及术后半年，进行分泌性中耳炎发病情况及中耳功能检测。

By using liposome-mediated gene transfection technology, plasmid pCMVSV40T/PUR containing SV40Tag was transfected in primary embryonic precartilaginous stem cells, while non-transfected cells served as negative controls.

利用脂质体介导基因转染技术将含有SV40Tag的质粒pCMVSV40T/PUR转染原代胚胎前软骨干细胞，以未转染细胞作阴性对照。

When compared with preinduction values, there were significantpostinduction changes in multiple variables of the HF QRS inmany leads studied that were within previously described normallimits.

与诱导前比较，诱导后多导联 HF QRS 的多个变量有显著变化。

Methods: The transesophageal atrial pacing and electrophysiologic study were performed in 237 patients with history of tachycardia, if PSVT was induced, the patients received overdrive suppression or program prestimulation.

选择237例有心动过速发作史的患者进行食管心房调搏检查，如果诱发出阵发性室上速，进行12导联心电图记录后，予以短阵快速刺激或程序期前刺激终止之。

METHODS: The subjects were 13 consecutive Class II osseous malocclusions with mandibular retrusion treated with fixed inclined biteplate.

13例骨性安氏II类错牙合下颌后缩患者，经固定斜面导板进行Ⅰ期矫治，分别在治疗前、治疗开始、治疗中、治疗后拍摄双侧TMJ的MRI片进行观察和测量。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
