放射治疗的

objective:to assess its clinical significance in patients with adenoid cystic carcinoma at head and neck for radiation therapy.

目的：评价头颈部腺样囊性癌放射治疗的意义。方法：回顾性分析1971年4月～1996年4月收治的30例头颈部腺样囊性癌的临床资料，生存情况并与文献比较。

Methods 195 cases of cervix neoplasm underwent radiotherapy in vitro plus intraperitoneapl,accompanied with more mental care,health education and dietary instruction,more intensive care of radioactivity rectitis and cystitis.

对195例宫颈癌病人行体外+腔内放射治疗的同时，加强心理护理、健康教育指导、饮食护理和放射性直肠炎、放射性膀胱炎的护理以及安全管理。

For example, if the microvascular endothelial cell is the principal target of radiotherapy and damage to the epithelial stem cell is a secondary event, this relationship may also hold for endothelial cells and the tumor cells they support.

举例来说，如果微血管内皮细胞是放射治疗的主要目标，而上皮干细胞的损伤是继发性事件的话，内皮细胞与其所供养的肿瘤细胞的关系也是如此。

For example, if the microvascular endothelial cell is the principal target of radiotherapy and damage to the epithelial stem cell is a secondary event, this relatio hip may also hold for endothelial cells and the tumor cells they su ort.

举例来说，如果微血管内皮细胞是放射治疗的主要目标，而上皮干细胞的损伤是继发性事件的话，内皮细胞与其所供养的肿瘤细胞的关系也是如此。

The algorithms and experiments are useful in localizer researching as well as radiotherapy, parameters planning in active vision and image analysis in multiview vision system.

这些理论和实验不仅在计算机辅助手术的定位器研究中很有用，而且在放射治疗的精确定位，主动视觉的参数规划和多视角图象分析等应用领域都有一定的参考价值。

With the application of intensity modulated radiation therapy, there were more conformity and dose distribution to the target volume. It can increase the local control rate and further improve the survival rate. On the other side it can protect the surrounding normal tissue such as parotid gland, brain stem, spinal cord, etc. The incidence of xerostomia can be reduced. So the quality of life was improved.

而调强放射治疗的应用，有更好的适形度和靶区剂量分布，不仅能提高肿瘤的局部控制率，从而进一步提高生存率，还能降低腮腺的剂量，从而降低口干的发生率，同时脑干、脊髓的剂量进一步降低。

Objective:To observe the pulmonary protective effect and impacts of local chest radiotherapy in corpore levels of connective tissue growth factorand platelet-derived growth factor after Qingzaojiufei soup treatment in patients with advanced and mediate chest tumor.

目的：观察清燥救肺汤对局部中晚期胸部肿瘤放射治疗的肺保护作用及对结缔组织生长因子、血小板源性生长因子在体内水平的影响。

This paper discusses how the electron of the Linac can be used as the beam for radialion therapy after scattering and collimation.

文章阐明了如何将加速器的电子束经散射和准直以后成为放射治疗的医用射线束。

Methods Making the face mask with using laser orientation system and the ones without using this system.

结论激光定位系统在面膜制作中的应用可以提高水平两野间定位的重合性，提高肿瘤放射治疗的精度。
