The results indicate that both have well-developed nasals, frontal, opisthotic, and squamosal bones, but they have no orbitosphenoid, basisphenoid, pseudomesia bar, or supplemental maxilla.

研究结果表明：2种鱼均有发达的鼻骨、额骨、后耳骨和鳞片骨，上颌口缘由前颌骨构成，犁骨上具齿，上枕骨与额骨相接，左右顶骨分离，无眶蝶骨、基蝶骨、伪头中骨和辅上颌骨。

The recoery rate was calculated as follows;(JOA score at follow up_preoperatie JOA score)/(17 _ preoperatie JOA score) _ 100,15 and the surgical outcomes were classified into four grades based on the calculated recoery rate; excellent: recoery rate 75% or higher, good: 50–75%, fair: 25–50%, and poor: lower than 25%. Ealuation was made on radiographic findings, including the range of motion and the jaw diameter (a measured line from the posteroinferior corner of the ertebral body to the anterior aspect of the subjacent lamina) at the adjacent leels in group A and the affected leels in group B and the spinal canal diameter at the C4 leel in both groups. The C4 leel was chosen for this measurement, because the spinal canal is usually narrowest at this leel.

恢复率如下计算；（随访JOA评分-术前JOA评分）/（17-术前JOA评分）*10015，按计算的恢复率将手术结果分4级；优：恢复率75%或更高，良：50-70%，中：25-50%，差：低于25%。X线片结果评价，包括活动范围和颌直径（从椎体下后角到下邻椎板前方的测量线）在A组相邻水平与B组受影响水平及两组C4水平椎管直径。C4作为该侧量的选择是因为通常在此平面椎管最为狭窄。

阻塞性睡眠呼吸暂停低通气综合征患者的头影硬组织测量特征为：以下颌改变为显著的颅颌面硬组织结构向后上缩进和舌骨至下颌平面距离明显地增加。

Owing to the common expression of EGF in various organs of mouse, it could be deduced that the role of EGF was mainly autocrine and paracrine actions, and its endocrine role was also not excluded owing to its high expression abundance in submaxillary gland.

由于EGF在小鼠各器官中表达的普遍性，可以推测EGF的作用以旁分泌和自分泌作用为主，但它在颌下等器官中的高表达表明其也具有内分泌作用。

Owing to the common expression of EGF in various organs of mouse,it could be deduced that the role of EGF was mainly autocrine and paracrine actions,and its endocrine role was also not excluded owing to its high expression abundance in submaxillary gland.

由于EGF在小鼠各器官中表达的普遍性，可以推测EGF的作用以旁分泌和自分泌作用为主，但它在颌下博士学位论文"TnEGFAlelittin"嵌合基因构建及有关基因重组表达的研究等器官中的高表达表明其也具有内分泌作用。
