The Anonymous Spectator

In this article, I attempt to illuminate points of similarity between the process of “working through” in psychological treatment, and the ordinary day-to-day developmental potential of college life, suggesting that when students can be helped to make optimal use of the college interpersonal milieu, brief, analytically informed psychotherapy can work in concert with the average, expectable experimentation of late adolescence to facilitate growth and maturation.     

3-D颞骨模型的制作与应用

目的探讨利用粉末堆积打印技术制作的高仿真3-D颞骨模型在解剖技能训练及模拟手术中的应用。方法利用高分辨率CT获取活体颞骨断层图像(正常人2例,慢性中耳炎患者2例),数据导入Mimics软件行图像分割及颞骨三维重建,以石膏粉末为原料,利用粉末堆积快速成型技术打印出颞骨模型,重要解剖结构与组织(听骨链、面神经、位听器、炎性渗出及胆脂瘤等)以不同颜色打印,并在显微镜下进行手术演练。结果颞骨模型的硬度与人骨相近,模型表面及内部骨性标志明显,解剖精确度高,钻磨触感接近真实,满足颞骨解剖技能训练及模拟手术的要求。结论利用粉末堆积打印技术能制作出仿真度更高、更接近实际人体解剖结构的颞骨模型,帮助临床医生在术前全面了解患者的颞骨及周围组织解剖结构与病变情况,制定和优化手术方案,减少并发症。     

THE ANALYTIC RELATIONSHIP: INTEGRATING JUNGIAN, ATTACHMENT THEORY AND DEVELOPMENTAL PERSPECTIVES

abstract    This paper highlights some key features of a Jungian approach to transference and countertransference and suggests that a Jungian model has crucial aspects in common with contemporary views in attachment theory on the nature of the analytic relationship. The analytic relationship is examined in terms of the fundamental processes of psychic development described in attachment theory and affective neuroscience, namely affect regulation and development of reflective function and of self-agency. The relative value of three analytic techniques, those of interpretation, new relational experience and regression, are discussed in relation to these processes. I suggest that each of the traditional psychoanalytic and Jungian analytic models concentrates on differing aspects of these psychic processes and analytic techniques. I construct a grid to illustrate this and to demonstrate how attachment theory and developmental neuroscience offer a theoretical basis on which we can develop an integrated model of the nature of the analytic relationship and tasks.     

非常规拔牙矫治在正畸治疗中的应用

目的：总结分析非常规拔牙矫治的临床经验。方法：非常规拔牙矫治病例29例（男性9例，女性20例），年龄12—30岁，平均18．4岁。根据患者的具体情况，分别结合以下非常规拔牙法进行矫治：拔除一个上中切牙、二个上侧切牙、一个上侧切牙、二个上尖牙、一个上尖牙，一个下中切牙、一个下尖牙、一个下第一磨牙，一个第二磨牙等。结果：所有病例治疗结束后拔牙间隙关闭，前牙覆牙A、覆盖基本正常，后牙咬合关系良好，面貌协调，侧貌美观，患者满意，达到了矫治的目的。结论：在特殊情况下，矫治目标可遵循个性化原则，采用非常规拔牙矫治，可以缩短疗程，达到与患者愿望一致的矫治目的。     

Application of 3D printed head film fixation technology in radiotherapy for head tumors

Objective To customize the individualized 3D printed head film for patients with head tumors undergoing radiotherapy, and to evaluate the physical properties of the material and the precision of this technology compared with the thermoplastic head film. Methods The 3D printed head film and thermoplastic head film were placed on the solid water surface, and the depth and surface dose were measured at 5 cm by ionization chamber and film, respectively. Thirty patients with head tumors receiving radiotherapy were randomly divided into the control and experimental groups. The patients were fixed with thermoplastic head film and 3D printed head film. The translational and rotational errors in the x, y and z direction were obtained by CBCT. Results The radiation attenuation rate of two materials at the depth of 5 cm was less than 1%. The dose of thermoplastic head film in the surface position was increased by 27%, and increased by 18% in the 3D printed head film. In two groups, 116 sets of setup errors were collected. The average translational setup errors in the control and experimental groups were 1.29 mm and 1.16 mm, 1.42 mm and 1.24 mm, 1.38 mm and 1.16 mm, respectively, and the average rotational setup errors were 1.29°and 1.08°, 1.02°and 0.96°, 1.01°and 1.00°, respectively. The translational setup errors in the y and z direction and rotational setup errors in the x direction significantly differed between the control and experimental groups (all P<0.05), but no statistical significance was found in the other direction (all P>0.05). Conclusion The 3D printed head film fixation meets the precise setup requirements of modern radiotherapy, which deserves further application in clinical trials.
