Approximately 5% of subjects who had a perforation died within 14 days of the procedure. Risk of death was significantly increased by perforation after colonoscopy (OR, 9.0; 95% CI, 3.0 - 27.3) or after sigmoidoscopy (OR, 8.8; 95% CI, 1.6 - 48.5). The difference in risk between the two procedures has been narrowing because the risk of perforation from colonoscopy has decreased over the years, presumably from improvements in technology and in training.

约有5%发生肠穿孔的民众在筛检后14天内死亡，做完直肠镜或大肠镜后发生肠穿孔的民众死亡率明显增加（大肠镜：危险比，9.0；95%信赖区间，3.0 - 27.3；直肠镜：危险比，8.8；95%信赖区间，1.6 - 48.5），但这两种筛检方法的风险差异正在逐渐缩小中，可能是因为技术的改良与人员的加强训练，使得大肠镜的肠穿孔危险已逐年下降。

Gallica were exposed under ultra-violet ray and the mutants were screened in RBBR-containing PDA plates, and then the laccase activities of the mutated strains were determined by ABTS.

In this paper, an efficient and easy biological screening method based on the sensitivity to lovastatin of Neurospora crassa was built to deal with the mutant strain rudely by UV mutation. A high-level strain was screened in the shaking flask culture incorporating with TLC and HPLC. A comparison between this two methods also was originally discussed while identifying dyeing using bromophenol blue as the better treatment of TLC, and offering a kind of simple, practical, fast and economical determination qualitatively and quantitatively.

本文有鉴于此，通过紫外诱变处理，并基于粗糙脉孢酶对洛伐他汀的生物敏感性，对诱变菌株进行了初筛；同时，采用摇瓶培养，结合TLC和HPLC的分析方法，复筛出一株高产菌株；对复筛过程两种分析方法分别进行了初步探讨，比较其优劣，确定TLC法经溴酚兰显色剂显色处理为较佳方式；从而，建立了一套简单、实用、快速、经济且有效的洛伐他汀生产菌诱变筛选方法。

A screening and cultivation method for Bacillus thuringiensis of high-yield high temperature resisting protease includes the following steps: high-yield high temperature resisting protease Bacillus thuringiensis Bt140 is obtained through adopting casein substrate agar to identify flat primary screen and fermenting enzyme activity measuring secondary screening; Plackett-Burman design and response surface analytical method are adopted to obtain optimal fermentation zymogenic formula and fermentation condition for Bt140 quickly; finally, shaking fermentation level reaches to 918.56U/mL.
