Recent study showed that the devitalization of DPC4 gene was present in nearly 50% of pancreatic carcinoma, which interrupted the TGF-βsignal pathway, so inactivation of DPC4 gene maybe one of the most important cause of pancreatic carcinoma. The present study was carried out to clarify the effect of DPC4 gene on human pareatic carcinoma cell line JF305, which can help us understand the growth and proliferation mechanism of pancreatic carcinoma and provide us the practical guidance on gene therapy of pancreatic carcinoma.

最新研究资料表明近一半的胰腺癌存在DPC4(deleted in pancreatic carcinoma)失活，进而使TGF-β信号传导途径中断，失去其对肿瘤细胞的抑制作用，导致细胞过度生长和增殖，因此DPC4的改变可能是胰腺癌发生、发展的重要原因之一[2]。

Use somatostatin after PD can restrain organism excrete diastase vera,and help anastomotic stoma to concrescent and decrease pancreatic leakage;pancreatic leakage should be treated by different grades,grade 1 can be cured by persistent drainage with somatostatin and nutritional support;grade 2 should be pay more energetic intervention.

PD后应用生长抑素持续泵入可以抑制胰酶的作用，使胰肠吻合口较好地愈合，从而有效地减少胰漏的发生；胰漏可进行分级治疗，Ⅰ级胰漏采用通畅引流为主，同时使用生长抑素和营养支持等治疗多可治愈，Ⅱ级胰漏需要积极治疗。

The development and the application of electronic design automation technology not only cause revolutionary change to the design and manufacture of electronic system, but also bring forward new requirements on the Didactics reform of relative college courses.

电子设计自动化技术的发展与应用不仅使电子系统设计与制造发生了革命性的变化，也对高等院校相关课程的教学改革提出了新的要求。

The evolvement of Diffluence River is the more complicated than Single River, because the diversion"s thing is changed with channel"s distortion. The river diversion is the general reflection of a good many factors, which mutually influence and adjust. In particular, when main channel occurs scouring-silting change, which causes the movement of water, sediment, and river bed in river system, the diversion will more be changed, with the study on division of discharge and sediment been further into, some practical engineering problem are solved.

目前，在对河道分流的认识与治理开发上虽取得了不少成绩，但随着社会经济的发展，人们对分流河道演变规律的认识与治理要求越来越高，随着人类对河流改造活动的加剧，河道的水沙条件可能发生急剧的改变，这些变化有可能使分流分沙的缓慢变化加剧，甚至改变原来的分流规律，许多研究者对分流分沙进行了较深入的研究，并能较好地解决了工程实际问题。

So a diktat from a right-wing president of the republic provided a dramatic twist to the tale.

这样，来自一个有右翼倾向的法国总统的命令使故事发生了急剧转变。

The periventricular area is one of those structures related to visual perception. Nearly all preterm infants with spastic diplegia exhibit cystic periventricular leukomalacia. Therefore, it has been wondered if children with diplegic cerebral palsy were at risk of visual perceptual impairment.

若处理视觉讯息的相关脑区受伤时，将导致视知觉缺损发生，使个体无法对视觉资讯做正确解释及运用，过去研究及临床上均可发现，脑性麻痹儿童有相当高的比例患有视知觉缺损。

Using director instead of directress does not mean a woman will necessarily enjoy the same opportunities today a man might .

通过社会观念等的变化使语言自然而然地发生变化，最终实现：无论是社会中，还是语言中，性别歧视只是一段永远的过去。

LC filter is an important part of this hybrid reactive power dynamic compensation. The parameters of capacitor and inductive winding of LC filter change during operation with the changing surrounding temperature, the self-heating and the insulation ageing of capacitor, etc. During the installation and commissioning, there may exist errors that can deviate the actual parameters and correspondent harmonic oscillation frequency from the designed value and result in filter disarrangement.

LC滤波器是动态无功补偿装置中的重要组成部分，由于它的电容器和电感线圈参数，在运行过程中会因周围温度的变化、自身发热和电容器绝缘老化等因素影响而发生变化，在安装和调试过程中会存在误差，从而使实际参数和相应的谐振频率偏离设计值，导致滤波器失谐，这就要求对滤波器进行优化设计。

One morning early, lying in my bed, andfilled with thoughts about my danger from the appearances ofsavages, I found it discomposed me very much; upon which thesewords of the Scripture came into my thoughts,"Call upon Me in theday of trouble, and I will deliver thee, and thou shalt glorifyMe."

感谢上帝，上帝的圣灵用上帝的语言教导我们，引导我们认识真理，使我们心悦诚服地服从上帝的指示。所以，即使我们十分了解造成世界上巨大混乱的那些宗教上的争执，在我看来对我们也毫无用处。现在，我还是把一些重要的事情，按发生的先后顺序，继续讲下去吧。

In addition, the presentation of the plot in Beloved are discontinued by many interruptions, which, to a certain extent, may engender a sense of disconnectedness and fragmentation; however, the intrinsic connection between the novel's temporal and spatial relations does ensure an artistic entity of the novel's structure, which in turn helps the events in the novel to be clearly presented and highly linked to one another.

另外，小说《宠儿》的非连续性的情景发展在一定程度上造成了小说结构的分散和不连贯，但小说中时间和空间的内在联系如蓝石路124号和发生在那里的事件，不仅确保了小说拥有明晰故事结构，促进了事件的再现，还使事件与小说中时间和空间的变化保持紧密地联系。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
