  • 简介:瞄准:探索门静脉的影响,并且为PVA的临床的申请建立一个理论基础在门以后的血液动力学的变化仙子上的静脉的动脉血化(PVA)胆汁的脉管的丛(PVP)词法结构和肝的病理。方法:Sprague-Dawley老鼠随机被划分成控制和PVA组。在PVA以后,门静脉的血液动力学的变化和hepatohilarPVP的词法结构用Doppler超声,肝功能测试,墨水灌注透明性管理和计算机的三维的重建被观察微可视化,和病理学的检查从胆汁管墙和肝在织物上被执行。结果:在PVA以后,门静脉的代表性的区域和血流被增加,并且增加随着时间的过去变得更重要,在某个范围。如果在PVA限制流动的措施没被采用,高血流将导致肝内门静脉和它的分支的膨胀,在大桶集成通信适配器内膜在骨胶原和纤维退化增加。除了glutamic焦葡萄酸转氨酶(通用终端),另外的肝功能测试是正常的。结论:有某个流动和氧含量的血为充满PVP并且遇见胆汁管墙的需氧量是重要的。在PVA以后,维持有在arterialized门静脉的高氧含量和高流动的血可以由并行管倒流充满PVP的hepatohilar胆汁管墙的正常形态学是解剖基础。限制血流的一项足够的措施在PVA是必要的。

  • 简介:作为一个挡土墙,门水注射板桩(PWISP)在2000出现在海岸工程。尽管有许多系统的方法,处理这个问题,在新结构上有在定义在二堆积之间的地压的因为困难的很少的集中。一个新方法在这篇论文被建议获得在PWISP之间的地压。对翻的稳定性分析作为后果列在后面。用FiniteElement分析(FEA)软件ANSYS,两个都,接触元素的土壤和那些的非线性的特征被考虑在接触表面上获得地压分发。基于FEA的结果,Rankin“s理论和slip飞机理论,在堆积之间的内部表面上的地压的公式被给。作为对它起作用的外面的力量作为分析目标和地压假定PWISP,对PWISP翻的稳定性的方程被介绍。最后,一些参数对翻关于PWISP的thest能力被讨论,例如前面堆积,在二排堆积之间的距离,内部磨擦角度和地球的结合的嵌入的深度。结果证明结合和内部磨擦角度的增加将减少距离和嵌入的深度,并且因此对翻提高稳定性。明确地,当距离是最大的挖掘深度的1/3-2/3时,二排堆积在稳定性给最好的表演。

  • 简介:门高血压(PHT)gastropathy是肝肝硬化的经常的复杂并发症,带之一从肝硬化死亡引起。Apoptosis广泛地被认为从坏死的房间死亡是房间死亡和一个不同实体的一个活跃精力依赖者模式。胃的mucosalapoptosis是否涉及PHTgastropathy,是不清楚的。通过cyclooxygenase(艇长)生产的前列腺素(PG)被认为从损害和apoptosis在胃肠的mucosa的保护起一个关键作用。然而,在PHTgastropathy的艇长的角色仍然不清楚地被理解。这研究的目的是调查(1)胃的mucosalapoptosis是否涉及PHTgastropathy,(2)艇长的downregulation贡献这apoptosis。在这研究,当mucosal增长在PHT老鼠被禁止时,我们证明胃的mucosalapoptosis显著地被增加。胃的mucosalCOX-1显著地在mRNA和蛋白质层次被压制,并且PGE2在PHT老鼠被减少。进一步,PGE2处理在PHT老鼠压制了胃的mucosalapoptosis。然而,胃的mucosalCOX-2层次没在假冒操作老鼠和PHT老鼠之间不同。肿瘤坏死因素的胃的mucosal层次--(TNF-)并且船边交货ligand,然而并非TNF相关的导致apoptosisligand,被增加,并且激活的caspase-8和caspase-3层次是在PHT老鼠的upregulated。到cytosol的从线粒体的细胞色素c的版本没在PHT老鼠被观察。我们的数据显示COX-1的downregulation经由死亡涉及胃的mucosalapoptosis调停信号的类型--我在PHT老鼠的房间死亡。

  • 简介:AbstractPurpose:Recurrent dislocation of shoulder (RDS) is a common injury in high demand professionals, like athletes and military personnel. The treatment for the patients with Bankart lesion is the arthroscopic repair. This present study compares the outcomes of two different techniques of arthroscopic Bankart repair i.e. a standard two anterior portals technique and a single anterior portal technique in patients with RDS.Methods:Patients with traumatic RDS met the inclusion criteria were managed with Bankart repair using either two anterior portals (Group A) or a single anterior portal (Group B) technique. Patients were evaluated before the intervention and at the mean follow-up of approximately two years using Rowe score, Oxford shoulder score and Tegner activity scale.Results:The mean age of the patients in Groups A (n = 34) and B (n = 37) was 29.64 years and 29.05 years respectively (p = 0.66). The dominant shoulder was involved in 27 patients in Group A and 22 patients in Group B (p = 0.069). The operative time in Group A and B was 68.52 min and 46.35 min, respectively (p < 0.001). The complications at follow-up, the mean Rowe score and Oxford score improved significantly in both groups compared with the pre-operative values. However, the final outcome scores were not significantly different between the both groups. The median Tegner's score preoperatively and at follow-up was 7 and 6, respectively in Groups A and B.Conclusions:Single anterior portal technique is an effective treatment modality, yielding a similar outcome as two anterior portals technique in the management of RDS.

  • 简介:AbstractIntroduction:Portal venous gas (PVG) is common in necrotizing enterocolitis and occasionally occurs in neonates after umbilical vein catheterization (UVC). Therefore, determining the cause of PVG requires further clinical evaluation in these cases.Case presentation:We report the case of a very-low-birth-weight infant who underwent UVC after birth. PVG was an unexpected finding on ultrasound following catheterization. The UVC was immediately removed and replaced with a peripherally inserted central catheter. The infant’s physical examination was unremarkable. Bedside X-ray revealed neither PVG nor pneumatosis intestinalis, which would indicate the onset of necrotizing enterocolitis. After full evaluation, breastfeeding was started on the same day. The infant did not develop feeding intolerance, necrotizing enterocolitis, or other disorders.Conclusion:PVG occasionally occurs in neonates who undergo UVC and is considered to be caused by exogenous gases. PVG is more easily detected with ultrasound than with X-ray and does not affect early feeding in premature infants.
