Methods: Fifty-fix adolescents were chosen and divided into first premolar extraction and nonextraction groups, with 30 and 26 patients respectively. The pretreatment and posttreatment panoramic radiographs were taken. The indexes of third molar eruption space, distance from third molar to occlusal plane and the length of mandible were measured and analyzed.

选择56例上下颌第三磨牙均存在的患者进行方丝弓正畸治疗，按照第一前磨牙拔除与否分为拔牙组（30例）和非拔牙组（26例），利用术前术后曲面断层片对患者上下颌第三磨牙萌出间隙、第三磨牙与胎平面的距离以及下颌长度进行测量分析。

Pantagraph - Bloomington bass expert Terry Brown of Bassfan.com has been instrumental in a decision last week by the Illinois High School Association to look into the possibility of offering competitive bass fishing at the high school level.

受电弓-布鲁明低音专家特里布朗b assfan.com一直在作出决定的最后一周，由伊利诺州高中协会，以研究可否提供具竞争力的低音捕鱼在高中水平。

After injection of FG into the NTS, FG retrogradely labeled neurons were present bilaterally with a strong ipsilateral predominance in the hypothalamic regions, such as medial and lateral parvicellular portion of the paraventricular nucleus, posterior

将FG注入孤束核后，在下丘脑室旁核小细胞部、穹窿周区、下丘脑后区及弓状核等核团内都观察到数量较多的FG逆行标记神经元；EM1和EM2阳性神经元的胞体主要位于下丘脑背内侧核、腹内侧核

The addition of intermediate screws at the fracture levels enhances the biomechanical stability of a short-segment pedicular fixation, and aids the height recovery and reduction of vertebral body.

附加伤椎置钉较传统的4枚螺钉固定可增加生物力稳定性，有助于椎体高度恢复的保持和复位。关键词：椎弓根螺钉；生物力学；运动范围

The majority of clinical studies using intraoperative neurophysiologic monitoring in spinal trauma focus exclusively on somatosensory-evoked potentials, and there are no specific article on the use of transcranial motor-evoked potentials, and stimulated electromyography by direct stimulation of the pedicular screws in thoracolumbar burst type fractures.

研究背景概述：大部分脊髓创伤患者术中神经生理监测的临床研究均集中于体感诱发电位，尚未发现专门的文献采用经颅运动诱发电位、胸腰段爆裂型骨折术中通过直接刺激椎弓根钉诱发肌电图来行脊髓神经生理监测。

Objective. 1. There was few researchers who mentioned pericementum which has some effect of resistance to sliding when they studyed the friction of archwire-bracket.

一、研究目的： 1、鉴于目前在测定弓丝与托槽滑动阻力时，均没有考虑到牙周膜对滑动阻力的影响，因此本实验尝试建立一种新的实验模型，分别模拟牙，牙周膜，牙槽骨。

It is more than one hundred years since Tomes initially put forward the concept of perioral muscle pressure and the Equilibrium Theory. Afterwards, plentiful results were achieved. Research on this field is of great importance in orthodontics.

自从1873年Tomes首次提出了口周力的概念以及牙弓内外肌压力平衡理论以来，至今已有一百多年的历史了。

The surfaces of cut bone were healed at 6 months after operation, without complications of pseudoarticulation formation or correction loss.

但也有学者指出后路椎弓根截骨减压虽然非直视下手术，仍可获得彻底的减压，且矫形的效果更好。

MSG could insult the functions and structures of specific brain areas of adult mice through blood-brain barrier. The ability of discrimination learning in Y-maze was affected markedly, especially in 4. 0g/kg MSG group, meanwhile, dark pyknotic and loss of neurons were shown in arcuate nucleus of hypothalamus, but not in hippocampus. Consistent changes occured in mitochondrial membrane protein bound 〓 by 〓-fluoresent probe, i.

MSG可以透过成年小鼠血脑屏障产生神经毒性作用。4.0g/kg MSG对小鼠空间分辨学习能力的损伤程度较2.5g/kg MSG更为明显，同时下丘脑弓状核神经元出现核固缩及神经元数目明显减少，相同处理未引起海马神经元的明显变化。

A recurve bow coated in fibreglass has become standard, and arrows made of aluminium and carbon graphite can travel more than 240km/h
