MATERIALS AND METHODS: Arg to Ser mutation was introduced into the 249 position of the p53 gene by knock-in method. These ES cells with this mutation were selected according to the homologues-recombination with PCR and Southern blot. The positive ES cells without a selection marker were injected into blastocysts recovered from Hprt(superscript -/-) mice, which were derived from Hprt-deficient ES cells. The injected blastocysts then were implanted into pseudopregnant females.

材料与方法：利用基因打靶技术在小鼠胚胎干细胞p53基因249编码子中引入点突变，使编码子249由精氨酸变成丝氨酸，然后将含突变的ES细胞显微注射到Hprt小鼠囊胚中，将注射过的囊胚植入假孕的雌性小鼠子宫，到第14d取小鼠胚胎纤维母细胞，用含HAT的培养液筛选出从ES细胞分化而成的鼠EF细胞，经测序证实细胞含有由249Arg到Ser的突变。

this paper discussed several untestable assumptions which were often used in epidemiologi-cal observational studies,and some paradoxical results that may arise under different assumptions were showed.simpson's paradox and lord's paradox were introduced.assumption of treatment assignment in causal inference of epidemiological studies,assumption of control group in evaluation of exposure ef-fects,and assumption of missing data mechanisms in incomplete data analysis were also discussed.

本文主要讨论流行病学观察性研究中几种常用的假定，介绍simpson's悖论和lord's悖论，逆回归问题，以及在不同假定下可能出现的相互矛盾的结果。探讨流行病学研究的因果推断中处理分配机制的假定，暴露作用评价中对照组的模型假定，以及不完全数据分析中缺失数据机制的假定。
