Contemporary engineering values play an important role in engineering education. This paper has analyzed the essential contents of contemporary engineering values in comparison with the traditional values. Then the problems of overemphasizing scientific and technological rationality in traditional engineering education are studied. At last, the corresponding strategies of engineering education are dealt with based on integrated rationality and contemporary engineering values.

Here, we demonstrated in this work that CsrA performs a negative regulator of the cel expression. cel, encoding lysis protein (LysE7), is located downstream of the colicin E7 structural gene in the ColE7 operon. Lysis protein was essential for colicin release and causes a decline in culture turbidity as well as lethality of the host cell when overproduced. Western blotting analysis of the level of LysE7 in the wild-type and csrA mutant strains was examined.

在本论文中，我们进一步发现到CsrA对於cel 基因的表现具有抑制的现象。cel 基因位在质体ColE7-K317上的E7大肠杆菌操纵子，可以制造出溶菌蛋白质(lysis protein， LysE7)，协助大肠杆菌素及免疫蛋白质的复合体运送至菌体外；但当菌体产生过多的溶菌蛋白质，则会导致宿主细胞的死亡，所以溶菌蛋白质的表现必须受到严密的调控，避免菌体产生过量，而CsrA则是目前第一个被发现到能调控溶菌蛋白质表现的因子。
