As the editorialist notes, unmeasured confounders as well as patient and physician preference may have influenced the results of both studies, and longer follow-up is necessary to confirm the relative safety profile of DES; nonetheless, these reports provide useful data for making better-informed decisions.

正如述评者指出，潜在的混杂因素，比如患者和医生的篇号，可能影响这两项研究，而且我们有必要进行长期的随访以确认药物洗脱支架的相对安全性。虽然如此，这两项研究为作出更好的指导性意见提供了有价值的信息。

This may eventually cause problems with patient access to these new therapies, the editorial suggests. All of the targeted therapies available to date are added onto conventional treatment, thus adding costs to the healthcare system."When the goal is to improve the chance for a cure, these new treatments seem to be well worth the expenditure," comments editorialist Hyman Muss, MD, from the Vermont Cancer Center, in Burlington."However, when the goal is to improve the quality of life or delay the time to progression by several months, as it is with many treatments for metastatic breast cancer, it is less clear whether the health system can and should bear these expenses."

当病患最终接触到这些新疗法时可能会发生问题，主编表示，目前为止，这些新的标靶疗法都是加在传统疗法之上，这对医疗系统造成负担；布灵顿Vermont 癌症中心Hyman Muss医师表示，当目标放在治癒时，这些新疗法是值得研究的，然而，当目标放在改善生活质量与减缓疾病进程时，仍有许多其它疗法可以选择，这些新药物应用在这种情形下的角色仍不清楚，且应该考虑医疗系统是否能够或是是否需要负担这些费用。

这是大家第一次开始真正了解这些宇航员，加略特说，他和哈利克已经感觉到一开始人们把他们看作老太空游客，但他们学会了足够让别人明白自己意思的俄语，并逐渐能够履行自己的义务。

You may have read that loss of collagen and elastin, as well as decreasing levels of hyaluronic acid contributes to wrinkles, age spots, sagging and other similar issues.

您可能已经读到损失的胶原蛋白和弹性蛋白，以及水平的下降透明质酸有助于皱纹，年龄点，下跌和其他类似的问题。

Utilizes on in the manufacture process the monolithic integrated circuit principle knowledge and the electronic circuit elementary knowledge as well as other electronic principle knowledge. May say is hundred rivers collects the sea,The content very is complex,Also has using on software many for example: Great W2000、Protel 99 and so on.

在制作过程中运用上的单片机原理知识和电子电路基础知识以及其他电子原理知识，可说是百河汇海，内容很是复杂，运用上的软件也有许多如：伟W2000，Protel 99等。

For a monotone twist map the well-known Birkhoff fixed point theoremsays that the circles with rational rotation number will break up whence a finitenumber of pairs of periodic points arise,half of which are elliptic and the othershyperbolic.Moreover,around each elliptic periodic point a few of new invariantcurves will appear and make a picture of phase space with a self-similar structure.Again one may ask is there a similar picture for higher dimensional Hamiltoniansystems?

对于单调扭转映射，著名的Birkhoff不动点定理指出，在通有情况下旋转数为有理数的不变曲线一般会破裂，在原来的不变曲线附近会产生有限多对周期点，其中一半是双曲的，一半是椭圆的，而在椭圆型周期点的周围又会产生一圈圈的不变曲线，使得椭圆周期点附近的动力学行为和整个相空间的动力学行为十分相象，换句话说，整个相空间具有无限嵌套的自相似结构，自然又产生了一个问题：对于自由度数目大于2的高维哈密顿系统，其相空间是否有类似的图象？

By the observation of sturdiness, weakness, obesity or emaciation as well as the posture of the movement and stillness, different kinds of diseases may he found out.

The fused insecticidal protein may delay the process of insects?developing resistance. After investigation of the secondary structure and action mode of Bt insecticidal protein and Cowpea trypsin proteinase inhibitor, as well as the action mechanism of insect enterokinase, we devised the fusion gene on the base of maintaining their functions respectively. The method follows: CpTI gene is linked to 3?-end of GFM crylA gene by a nucleotide sequence encoding cleavage site of insect enterokinase.

根据Bt杀虫蛋白Cry1A和豇豆胰蛋白酶抑制剂的高级结构、杀虫机理及昆虫体内肠激酶的作用机理，本着尽量不影响二者功能的原则，设计出了构建Cry1A和CpTI融合杀虫基因CryCI的方案，即将CpTI基因的编码序列连接到GFM Cry1A基因编码区3'端，并在其间用一段编码肠激酶切割位点的序列相连。
