Some CT characteristics of BCSDH were studied first.Then,the risk factors for BCSDH were determined by logistic regression model from the following variates: age,gender,prediagnostic duration,site for injury force,coma experience and CT showing after injury.

先研究其CT表现，然后采用多因素Logistic回归分析从以下变量中，如年龄、性别、伤后&潜伏&时间、受伤着力部位、受伤时有无昏迷经过、伤时CT表现等确定BCSDH发生的影响因素。

objective to explore some ct characteristics and risk factors for traumatic chronic bilateral subdural hematoma.methods a total of 52 patients with chronic subdural hematoma were reviewed.some ct characteristics of bcsdh were studied first.then,the risk factors for bcsdh were determined by logistic regression model from the following variates: age,gender,prediagnostic duration,site for injury force,coma experience and ct showing after injury.results bcsdh was observed in 44.2% of 52 patients with csdh.

作者单位：第三军医大学大坪医院野战外科研究所神经外科，重庆 400042 目的探讨创伤性双侧慢性硬膜下血肿的ct特征及危险因素。方法回顾有随访资料的创伤性慢性硬膜下血肿52例。先研究其ct表现，然后采用多因素logistic回归分析从以下变量中，如年龄、性别、伤后&潜伏&时间、受伤着力部位、受伤时有无昏迷经过、伤时ct表现等确定bcsdh发生的影响因素。

The ratio of mild-to-moderate uc was 76.6% and 59.6% of the patients were aged from 30 to 50 years. the clinical features of uc were abdominal pain, diarrhea mixed with pus, blood, and mucus. endoscopy indicated edema, hyperemia, erosions and ulcerations in the mucosa, and 31.9% of cases were proctosigmoiditis, 36.2% were colitis of the left hemicolon.

临床表现以黏液便、脓血便、腹泻、腹痛为主，肠镜下主要显示黏膜充血、水肿、糜烂、溃疡等病变，多为直乙结肠炎(31.9%)和左半结肠炎(36.2%)，病理活检100%患者均表现为弥漫性炎性细胞浸润。

Polysomes change in number as "few-many-few-many" during the development of the egg, early zygote stage, zygote at dormancy, zygote in prophase of mitosis and two-celled proembryo in sugar beet, which indicates that such changes in metabolism as "low-high-low-high" activity may relate to the transformation from gametophyte to sporophyte generation.

根据上述结果可以得出，栽培甜菜从卵细胞成熟→合子初期→合子休眠期→合子分裂前期→二细胞原胚的超微结构变化中多聚核糖体的变化最为显著，表现为&少→多→少→多&的数量变化过程，反映出细胞代谢状态也经历了&弱→强→弱→强&的变化过程，这种变化趋势与配子体世代向孢子体世代转变有关。

The project implemented a systemic investigation to the pupa period of wild silkworm comparatively, which from Shanxi, Jiangsu, Sichuan, Chongqing, Guizhou provinces and so on. According to the investigation, the pupa dormant characteristic of Shaanxi wild silkworm was found, and the individual, which pupa period was more than two months was selected. Through the hybrid genetic analysis we found that the characteristics for a long period of pupa was controlled by polygene and genetic recessively and strongly influenced by environmental conditions at the same time. To compare the performance of pupa period of the pupa dormant wild mulberry silkworm, we designed different ecological conditions. The result indicating that the temperature is the main factor in the ecological impact, but the pupa period was extended at the same temperature conditions, indicating that the additive effects of the environmental factors.

本项目实施，系统调查比较了陕西、江苏、四川、重庆、贵州等省市的野桑蚕的蛹期经过，发现了陕西野桑蚕的蛹休眠特性，筛选获得了长达2个月以上的蛹期经过个体；通过杂交遗传分析，发现长蛹期特性表现为隐性遗传，受多基因控制，同时受环境条件的强烈影响作用；通过设计不同生态条件比较蛹休眠性野桑蚕蛹期经过的表现，表明温度是主要的生态影响因子，但相同温度的野外型条件下蛹期经过延长，表明受到环境因素的综合作用。
