It is also suggested that ACh plays an important role in the maintenance of excitability of cortical neurons.

这一作用可能是通过作用于M受体，影响突触前递质释放来实现的。

Results There were obvious mandible changes such as the increase of SNB angle and decrease of ANB angle and overjet after treatment with Twinblock, suggestive of mandible growth, increase of facial angle, reduction of mandible process angle, mild adduction of upper incisors, and mild anteversion of lower incisors.

Foetus in wrong position; abnormal fetal position; malpositionThe main injured parts included prolapse of lumbar intervertebral, muscles of waist and back myofascitis, epiphysitis of lumbar spine, malposition of lumbar spine and lumbar muscle strain.

结果表明：97.5%的运动员患有腰部损伤，100%的运动员表示有过不同程度的腰部疼痛；发病率前5位的损伤部位是腰椎间盘突出、腰椎峡部裂、棘突偏歪、腰椎错位和腰肌劳损；损伤多发生在重要赛事前准备期。

The primitive characteristics include long tail with more than 20 caudal vertebrae, which are surrounded by thin rod-like extensions of the zygapophyses and chevrons, and the fifth toe bearing two long digits, whereas the derived characteristics include an elongated skull with antorbital and nasal openings fused into a large nasoantorbital fenestra, long cervical vertebrae with reduced or absent cervical ribs. The length ratio of the wing metacarpal to the humerus is between the basal pterosaurs and pterodactyloids.

它既具有原始类群的特征：比如尾长，多于20节尾椎椎体，且尾椎椎体由极度加长的、纤细的前后关节突及脉弧所包裹，构成一僵硬的尾部，第五脚趾具有两个长的趾节；又具有进步类群的特征：比如头骨加长，鼻孔和眶前孔愈合为一大的鼻眶前孔，颈椎椎体长，没有或者颈肋退化；翼掌骨与肱骨的比率介于原始类群和进步类群之间。

The whole thesis is divided into nine chapters, its first six chapters focus on the analyses of terrorism, then the last three chapters turn to studying a new thinking of international cooperation against terrorism On the analyses of the part of terrorism with the first three chapters, I define terrorism as follows: Terrorism is a kind of action or thought in which it is the intentional use of, or threat to use ruleless violence or technical methods against civilians or against civilian targets, in order to attain political aims. What differs from other scholars' definitions is that the definition proposed states that terrorism is not only a political violence, but also a social trend of thought.

在前六章的对"恐怖主义"的分析上，本文提出了有别于他人的恐怖主义定义："使用或主张使用无规则的暴力或技术手段，或是袭击平民和或是袭击公用设施，以图达到政治目的的一种行为与社会思潮"，认定恐怖主义不仅是一种政治暴力行为，更是一种社会思潮；还对自杀性恐怖主义、恐怖主义的类型和划分、恐怖主义的历史与发展历程、恐怖主义形成的机理及理论解释等论题进行了较系统的理论探索，分析了伊斯兰原教旨主义与恐怖主义的关系；而且，还根据论文作者本人在国外调研掌握到的大量翔实的第一手资料，揭示了境外"东突"恐怖分子是"国际恐怖主义的一部分"的本来面目，并分析和预测了它们未来的发展趋势，提出了中国反对东突恐怖势力的若干建议。

ET tube insertion procedures were performed on 59 pediatric patients aged newborn to 17 years (33 boys) due to cardiopulmonary arrest or impending respiratory failure. Ultrasound images were taken before and after the procedure in two-dimensional and time-sector modes using a portable ultrasonic machine. The subxiphoid window at the mid-upper abdominal — just beneath the xiphoid process and the lower margin of the liver — was used most often, with a wide transducer sector angle (90 degrees) for bilateral scanning of the diaphragm.

这项试验对59位从新生儿到17岁（33位男童）的小儿科病患进行插管，插管的原因是因为心肺衰竭或是严重的呼吸衰竭；在插管前与后使用可携带式超音波机器进行二度空间与时间象限的超音波显影；最常使用中上腹的剑突影像，就在剑突与肝脏下下缘部份的影像，与以宽的转换区间角度（90度）作横隔膜双侧扫描。

Results: Two groups 64 sides joint equally to obtain limpid MR image, on oblique sagittal of close mouth T1 and PDW images showed that the anterior disc border in TMJ ID people was sited around 0.42mm, before the vertical line of the lower end of articular eminence,while it is sited 0.14 mm,before the vertical line in normals, There exists significant statistical difference. The junction of posterior band of the disc and the bilaminar region in TMJ ID people was sited at 14.4°of vertical line of condile center,but in normals it was 3.18°There exists significant statistical difference.

结果： 两组64侧关节均获得清晰的MR图像，T1WI和PDWI图像斜矢状闭口位时，在TMJ ID组关节盘前缘位于关节结节最低点垂直线前约0.42 mm，而正常对照组则位于其前约0.14 mm，两组间差异有统计学意义，在TMJ ID组关节盘后带与双板区交界处约位于髁状突12点位垂直线14.4°处，而正常对照组则位于其3.19°处，两组间差异有统计学意义。

Thicknesses of intertransverse ligament were measured, and the distribution of anterior branches from lumber nerve and vessel were observed.
