放射

［Purpose］ To investigate the relationship between radiation encephalopathy after radiation for nasopharyngeal carcinoma and radiotherapeutic field design.

放射性脑病（radiation encephalopathy，REP）是一种严重的放射治疗并发症，常见于头颈部恶性肿瘤放射治疗后，尤其多见于鼻咽癌治疗后。

Methods from Sept 2000 to March, 2002 516 patients with body tumor were therapied. The radiotherapeutic plan and set dosage distribution had been worked out on the basis of the carcinoma position, clinical target volume, patient health condition, and therapeutic aim. The isodosage curve was 50-90%. The fractional doses was 300-900cgy. The therapy had been repeated for 5-9 times for one patient, every two days one time. Results the patients were followed up 3 to 15 months after therapy.

采用OUR-QGD立体定向伽玛射线体部放射治疗系统治疗肿瘤患者516例，根据肿瘤的部位、临床靶体积大小、分类与治疗目的，如临床根治或姑息治疗，以及肿瘤周围的组织与器官、病人的身体状况、既往治疗情况、有无淋巴结转移等制定放射治疗计划及调整剂量分布， PTV覆盖95%以上CTV，等剂量曲线50~90%，中位值62.2%。

The transmission electron microscope revealed endoplasmic reticula were dilated, the matrix of mitochondria became pale and the cristae of mitochondria shorter in stromal cells from irradiation mice compared with those of controls.

提示：放射复合伤骨髓基质细胞的细胞周期比例、DNA含量和形态的改变可能是导致放射复合伤造血微环境损伤的重要原因之一。

Purpose To evaluate the effect of stereotactic radiotherapy in the treatment of brain metastasis.

目的 探讨 X线立体定向放射治疗在脑转移瘤常规放射治疗中的作用。

In the case of supraclavicular and internal mammary node irradiation, the dose was 44—50 Gy.

全乳分次放疗的放射总剂量为50Gy，在5周内分25次进行；对锁骨上或乳房内结节病例，放射总剂量为44—50 Gy。

Therefore even in the darkness of the deepest treasury the Silmarils of their own radiance shone like the stars of Varda; and yet, as were they indeed living things, they rejoiced in light and received it and gave it back in hues more marvellous than before.

因此，即便是在最深最黑暗的宝库中，精灵宝钻所放射出来的光芒，仍如瓦尔妲的星辰一般闪亮，何况，它们真的是活物，它们喜爱见到光，它们会吸收光，然後放射出比先前更灿烂千百倍的七彩光芒以为报。

Whereas the proximal part of the tetrapod limb skeleton can easily be homologized with the paired fin skeletons of sarcopterygian (lobe-finned) fish, there has been much debate about the origin of digits.

早期的假设认为，四足动物的足趾与鱼类的放射鳍同源，但根据发育研究结果，同时根据一种名叫&潘氏鱼&、与陆地脊椎动物密切相关的目前已经灭绝的鱼（这种鱼似乎没有末梢的趾状放射鳍）的鳍，这一观点似乎并不可靠。

None of the other potential prognostic factors evaluated (including patient age, gender, tumor grade, tumor location, subtotal resection, presence or absence of cranial nerve palsies, total dose, 3D conformal radiotherapy, duration of symptoms, or radiological response) were associated with patient overall survival in multivariate analysis.

以多变数分析评估其他一些可能的预后因子（包括病患年龄、性别、肿瘤的分化程度、肿瘤位置、是否接受手术切除、有无脑神经麻痹、放射治疗总剂量、三度空间顺形放射治疗、症状的持续时间、或影像学上肿瘤是否变大）均不影响病患存活率。

Methods: Both cell culture and MTT were used to observe the proliferation of mice spleen lymphocytes, YW was used for 15 days after radiation. To study the protective effects of mice scathed by free radical after radiation using TBA and DTNB.

采用细胞培养及MTT法，观察&养胃方&对荷瘤小鼠放射后脾脏淋巴细胞转化率的影响；使用TBA法和DTNB法观察YW对小鼠放射后自由基损伤的保护作用。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
