五个整数a、b、c、d、e，它们两两相加的和按从小到大顺序排分别是183，186，187，190，191，192，193，194，196，x．已知a＜b＜c＜d＜e，x＞196．（1）求a、b、c、d、e和x的值；（2）若y=10x+4，求y的值．
题型：解答题难度：中档来源：不详
由题知：a+b=183，a+c=186，d+e=x，c+e=196，又∵a+b、a+c、a+d、a+e、b+c、b+d、b+e、c+d、c+e分别对应着183、186、187、190、191、192、193、194、196中的某一个数，这些数之和为1712，即4（a+b）+4c+3d+3e=1712，∴4×183+4c+3x=1712，∴x=980-4c3，∵x＞196，∴c＜98，∵a+c=186，∴a＞88，∵这些数都是整数，由整数性质可知a≥89，b≥90，c≥91且c≤97，∴C只能在97、96、95、94、93、92、91中取值，又∵3x=980-4c=4（245-c）为整数，∴245-c能被3整除，而上述7个数中只有92、95满足，若c=92，∵a+c=186，∴a=94不满足a＜c，舍去；∴c=95，故a=91，x=200，∵a+b=183，c+e=196，∴b=92，e=101，∵d+e=x=200，∴d=99，综上可得：a=91、b=92、c=95、d=99、e=101、x=200．（2）y=10x+4=10×200+4=2004．

有理数除法
有理数除法定义：已知两个因数的积与其中一个因数，求另一个因数的运算叫做有理数的除法。有理数的除法法则：（1）除以一个数，等于乘上这个数的倒数；（2）两个数相除，同号得正，异号得负，并把绝对值相除；（3）0除以任何一个不等于0的数都等于0。有理数除法注意：①0不能做除数； ②有理数的除法和乘法是互逆运算；③在做除法运算时，根据同号得正，异号的负的法则先确定符号，在把绝对值相除，若在算式中有带分数，一般化成假分数进行计算，若不能整除，则除法运算都转化为乘法运算。

Epidermal growth factor (EGF) is a potent mitogen in vitro, but its biological role is less clear. The vulnerary effects of EGF were evaluated in a model of wound repair, the polyvinyl alcohol sponge implanted subcutaneously in rats. EGF was purified to homogeneity by reverse-phase HPLC and quantified by receptor binding assay and amino acid analysis. Preliminary data showed moderate promotion of granulation tissue formation by daily injections of 10 μ g of EGF. To test the hypothesis that long-term exposure to EGF is required for complete cellular response, the factor was incorporated into pellets releasing 10 or 20 μ g of biologically active EGF per day, and the pellets were embedded within the sponges. Slow release of EGF caused a dramatic increase in the extent and organization of the granulation tissue at day 7, a doubling in the DNA content, and 33% increases in protein content and wet weight, as compared with placebo controls. Although collagen content was also increased by almost 50%, the relative rate of collagen synthesis remained the same, suggesting that the morphological and biochemical increase in collagen resulted from increased numbers of fibroblasts rather than a specific stimulation of collagen synthesis. These results indicate that the local sustained presence of EGF accelerates the process of wound repair, specifically neovascularization, organization by fibroblasts, and accumulation of collagen.
