Interpretation of College Instructor' s Professionalization and Specialization ZHU Ping( Research Center of Marxism, Anhui Normal University, Wuhu Anhui 241000, China)The college instructors' professionalization and specialization are basically aimed at improving the effect of political and ideological education and characterized by stability and protraction.

高校辅导员的职业化、专业化的基本内涵可理解为：以提高辅导员思想政治教育的成效为目标，以教育的专业性、科学性为基本要求，以角色的稳定性和长期性为基本特征，使辅导员作为教师队伍的组成部分，逐步走向专门职业和特定专业的发展趋向和过程。

The results are as follows:(1) With the imposing of orthopedic force of simulating maxillary protraction on maxilla, in the sagittal direction, the maxillary complex of the SD Rats in experimental group grows more quickly than that in two control groups, and the extent of the maxillary complex increases more evidently. The maxillary complex displays anti-clockwise forward and upward rotation.(2) With the imposing of orthopedic force on maxilla, upper incisors exhibit labial-inclined, labioclination of lower incisors changes insignificantly, and the shape and the dimension of skull are not affected significantly.(3) The expression of TGF-3 , in frontomaxillary sutures and palatomaxillary sutures shows different intensity in different extent of time. But The expression of TGF-{3, in experimental group is more intensive than that in two control groups, and that in operated control group and natural growth group has no significant difference.

结果如下：在模拟上颌前牵引矫形力作用下，(1)生长发育期大鼠上颌复合体在矢状方向生长加快，长度明显增加，并表现出向前向上的逆时针旋转；(2)上切牙唇倾，下切牙的唇倾度没有明显变化，颅脑的形态与大小不受影响；(3)额颌缝和腭颌缝中TGF-β_1的表达，同一时段实验加力组要强于手术对照组与自然生长组，而手术对照组与自然生长组之间无显著性差异。

The increases in the cell density in the sutures of the treated groups were higher as compared to the two controlled groups for 3 7 14days indicating that cellular hyperplasia in the expanded sutures were accelerated by the protraction .The cell density in the palatomaxillary sutures and in the frontomaxillary sutures differed in increase ways at the two time points of 21th day and 28th day suggested that the mode of bone formation in the circummaxillary sutures is different from one another..5 The expression of Proliferating Cell Nuclear Antigen were always higher than the controls in the course of this study,which i

而在21、28天时间点两个骨缝与对照组相比在相同时间点增长程度明显不相一致，提示我们不同的上领骨周围骨缝在前牵引作用下改建方式过程可能不一。5、在上领前牵引作用下，上领骨的额领缝内的PCNA的阳性表达一直高于对照组，提示前牵引促进上领骨周围骨缝内细胞增殖活动增强。

The objects of this research were AngleⅢmalocclusion osteal cross bite patients who were treated by maxillary protraction therapy combined with rapid palatal expansion in the Department of Orthodontics, Stomatological College of FMMU, and they were divided into three different groups by age: the 3～6 years group, the 7～10 years group and the 11～13 years group.

本研究以在第四军医大学口腔医院正畸科行上颌前方牵引联合上腭快速扩大治疗的安氏Ⅲ类骨性反牙合病例为研究对象，并按年龄将其分为3～6岁组、7～10岁组、11～13岁组。

Through comparing and analyzing the photographs of Cephalometrics before orthodontics, after orthodontics and two years after orthodontics, we can probe into the optimal period for treating AngleⅢmalocclusion osteal cross bite patients with maxillary protraction therapy and the long period of stability after the accomplishment of orthodontics, and it can provide reference and theoretics for clinic practice and experiments.

通过对不同年龄组患者矫治前、矫治结束时及矫治结束两年后的头颅侧位片进行定点、描绘、测量、比较分析，进而探讨上颌前方牵引治疗安氏Ⅲ类骨性反牙合的最佳矫治时机以及矫治结束后的长期稳定性，为进一步的临床实践与实验研究提供理论依据。

Methods:Thirteen class Ⅱ patients (aged 10～13 years,male 6,femal 7) with mandible retrusion and slight maxillary protrusion were included.Radiographs of the left hand and wrist showed the patients were at the pubertal or pre-pubertal stage.All the patients were treated with the mandibular protraction appliance.

选择13例AngleⅡ类错牙合病人，男6例，女7例，最大13岁，最小10岁，均为替牙晚期或恒牙早期。X线头影测量显示主要为下颌后缩及轻微上颌前突，左手腕片显示为生长发育高峰期或高峰前期，所有病人用下颌前伸矫治器进行治疗。

Some clinically obvious phenomena are difficult to explain using this model system, for example, the phenomenon traditionally referred to as the "row-boat effect", where uprighting of the canines excessively tipped into an extraction site results in protraction of the molars and "anchorage loss".

一些临床上明显的现象是难以解释利用该模型系统，例如，传统的现象称为&行船效应&，在扶正的犬齿过分倒进萃取结果冗长的网站的臼齿和&锚固损失&。

All findings indicated that Angle Ⅲ skeletal anterior crossbite can be corrected successfully with reverse TBA combined maxillary protraction.

认为反式TBA联合前牵对上下颌软组织作用均较大，是矫治前牙反牙合的理想装置。
