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.results （1）tpot shortening was observed in hela cell after radiotherapy.

目的 探讨放射对宫颈癌hela细胞系再增殖的影响，为宫颈癌是否有必要实行非常规分割放疗提供一定的理论基础。方法在不同剂量的放射作用下，以台盼蓝染色细胞计数法分析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。

In the light of the paleoenvironmental significance reflected by the radiolaria, graptolite, brachiopod,sponge spicule and the rock character, its suggested that the greyish green mudstone at the basal WufengFormation of the Goujiaya section would be probably deposited in 60 to 100 meters deep water, theGuanyinqiao bed in 50 to 80 meters deep, and the radiolaria-bearing silicalite from Wufeng Formation inwater with 200 to 400 meters deep. Combining the above-mentioned water depth with the sea-level changecycles, the change range of every one of the 5 cycles could be further conjectured. They were in ascendingorder: 20～120 m, 80～130 m, about 150 m, 50～250 m, and in excess of 200 m.

根据放射虫、笔石、腕足类、海绵骨针以及岩性等对古环境的指示意义，认为五峰组底部灰绿色泥岩段产出时水深约60-100m，观音桥层水深约50-80m，在晚奥陶世最大海侵期(对应于T.typicus亚带下部)，水深约400m，五峰组含放射虫硅质岩沉积时最小水深约200m，结合以上海平面变化的5次旋回，从而推算出各旋回海平面的变化幅度：在第①旋回，海平面变化范围大致为20～120m；在第②、第③和第④旋回中，海平面变化分别为80～130 m、大约150 m和50～250m；第⑤旋回的海平面升降幅度大于200 m。

Alternative etiologies for the development of this disorder include intrauterine insult (ischemic, metabolic, or viral such as CMV) during the 12th to 24th week of embryologic development. This results in damage to the germinal matrix and radial glial cells. Radial glial cells act as mechanical guides by which neurons are transported to the outer cortex during development.

另一种病因可能是由于第12-24周期间的宫内损伤（缺血、代谢异常、或病毒感染如CMV），其结果导致生发基质和放射状胶质细胞的损伤，在神经元移行至外皮层的过程中，放射状胶质细胞充当着机械性向导的作用。

With the development in nucleus technology application,radiation source amount and eradiation accident both increased.

随着核技术应用领域的逐步扩展、放射源数量的增多及辐射事故突发频率的提高，2003年《中华人民共和国放射性污染防治法》发布并实施，该法明确了环境保护行政主管部门对放射源实行统一监督管理的职能。

All patients had locally advanced squamous cell carcinoma of the oral cavity, oropharynx, larynx, or hypopharynx, and were randomized to either radiation therapy once daily or radiation therapy once daily combined with three courses of high-dose cisplatin chemotherapy.

所有的病人都患有局限性晚期的口腔、喉部、咽部或者喉咽部的鳞壮上皮癌。这些病人被随机给予每日一次放射治疗或者在每日一次放射治疗的基础上加用三个疗程的cisplatin化疗。

They detected 112 sentinel lymph nodes in 71 patients (97%), including 64 (88%) in whom lymph nodes were stained blue after intraparenchmal injection of isosulfan blue, and 61 (84%) in whom lymph nodes were radioactive, reflecting uptake of radiocolloid injected intradermally.

研究者检测71位患者（97％）的112个前哨淋巴结，其中有64位患者（88％）的患者软组织注射isosulfan blue后，其淋巴结被染成蓝色，61位患者（84％）的淋巴结有放射活性，这反映皮内注射的放射胶体被吸收。

The article introduces recently some radioactive source accidents in China, and analyses the reasons of the accidents. Some important issues existed in the process of implementing new regulation were summarized, and some suggestions for managing radioactive sources are made.

本文通过介绍我国发生的一些放射源事故情况，分析事故发生的原因，总结了《放射性同位素与射线装置安全和防护条例》颁布后在实施过程中还存在的一些关键问题，提出了加强放射源管理的对策与建议。

Amaranth radiolarian silicate close connected with ophiolite slices are discovered in "Ma'erzheng Fm." along Huashxia — Long Stone Hill for the first time, and abyssal Early Permian radiolarians are got, thus provide important reference date for the forming age of ophiolite in this belt.

2首次在花石峡—长石头山一带的"马尔争组"中发现与该带蛇绿岩岩片有密切联系的紫红色放射虫硅质岩，并分离出丰富的深海相早二叠世放射虫化石，为该带蛇绿岩的形成时代提供了有重要价值的参考年龄。

Here we present a case of 21 year-old male who suffered from recurrent swelling in left side of mandible which had received surgery for ossifying fibroma in another hospital when he was 19 years old. Obvious facial asymmetry was noted but no sensory dysfunctions were detected. The lesion showed well-demarcated, multilocular radiolucency but radiopacity centrally. We applied segmental resection via extra-oral approach and reconstructed with anterior iliac crest bone graft. After removal of MMF in six week, the wound healed well and joint function was good without malocclusion. After follow-up of one year, no recurrences were noted.

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.
