Abstract］ Objective To explore the effect of radiotherapy on the auxesis of Hela cell in cervix carcinoma to offer the theory elements to identify whether or not the cervix carcinoma would be treated by radiotherapy with non-routine segmentation.Methods After radiotherapy with different doses,the Hela cells changes of potential doubling time by cytometry with trypanblau coloration were analysed,and the livability of clonogenic cell at the same time was detected by clone,and the two former were combined to aralyse the changes.

目的 探讨放射对宫颈癌Hela细胞系再增殖的影响，宫颈癌是否有必要实行非常规分割放疗提供定的理论基础方法在不同剂量的放射作用下，以台盼蓝染色细胞计法分析Hela在照射后不同时间点的潜在倍增时间的变化；以克隆形成实验检测其同期克隆源性细胞存活比率，并将两者结合分析。

The radiational ratio was analysed and it's changing of basing metabolizion's cerebral infarct and normal cerebral with using analysis technology of region of interest,as well as,the radiational ratio of with using same method after acupunctural metabolism.

Objective To determine the scattering and density effects of intrauterine contraceptive ring on pelvic radiotherapeutic dosage distribution.

目的 测量元宫型金属宫腔内节育环对放射治疗引起的密度效应及次级射线引起的散射效应对放射治疗剂量分布的影响。

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。

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。

PURPOSE: To investigate the combined effects of adenoviral-mediated p53(Ad-p53) transgene expression and irradiation response in nude mice models of lung adenocarcinoma (A549 and GLC-82).To determine whether wtp53 sensitizes cells to radiation independently of their p53 status and to investigate the interaction mechanism.

目的：本研究筛选了P53基因状态不同的两种人肺腺癌细胞系A549及GLC-82，分别建立裸鼠人肺腺癌移植瘤模型，使用E1复制缺陷型重组腺病毒介导的野生型P53基因瘤内注射治疗，观察其放射增敏作用并探讨其机制，同时比较不同P53基因状态对治疗的影响，为临床开展基因放射治疗提供实验依据。

Has been modified as follows: where Z is the ratio in efficiencies of fuel cell and internal combustion vehicles, Cg and APg are the cost/per MJ of gasoline and the corresponding AP emissions, and CH and APH are the cost/MJ of compressed (350 atm) hydrogen and the corresponding AP emissions

被修改如下：那里Z 是比率在燃料细胞和内部燃烧车效率， Cg和APg 是cost/per MJ 汽油和对应的AP 放射，并且CH 和APH 是压缩的(350 atm)氢和对应的AP 放射cost/MJ

Treatment interruption longer than 1 weeks did not take place.Conclusions Concurrent chemoradiotherapy is preferable for local advanced NSCLC. VIL can enhance the radiosensitivity of NSCLC. Cinical activity of the single agent vinorelbine as radiosensitizer can be continued.

本研究采用剂量的VIL用于同步放射治疗局部晚期NSCLC总有效率和完全缓解率优于单纯放射治疗，毒副反应可以耐受，提示VIL可以明显增加NSCLC放疗的敏感性，为临床NSCLC的合理治疗提供了理论依据。

Research on biological damages caused by various ionizing radiations is the frontier area of radiobiology and radiology. It is also the hot spot included in recent public focus.

电离辐射所致生物损伤的研究既是放射生物学和放射医学中重要的前沿领域，也是目前各方面所关心的热点问题。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
