| 1 | 为恶意、良性的胆汁的苛评的治疗的充分盖住的自我可扩充的金属 stents显示文摘 AIM:To present a series of covered self-expandable metal stents(CSEMS) placed for different indications and to evaluate the effectiveness,complications and extractability of these devices.METHODS:We therefore retrospectively reviewed the courses of patients who received CSEMS due to malignant as well as benign biliary strictures and postsphincterotomy bleeding in our endoscopic unit between January 2010 and October 2011.RESULTS:Twenty-six patients received 28 stents due to different indications(20 stents due to malignant biliary strictures,six stents due to benign biliary strictures and two stents due to post-sphincterotomy bleeding).Biliary obstruction was relieved in all cases,regardless of the underlying cause.Hemostasis could be achieved in the two patients who received the stents for this purpose.Complications occurred in five patients(18%).Two patients(7%) developed cholecystitis,stents dislocated/migrated in other two patients(7%),and in one patient(3.6%) stent occlusion was documented during the study period.Seven stents were extracted endoscopically.Removal of stents was easily possible in all cases in which it was desired using standard forceps.Twelve patients underwent surgery with pylorus preserving duodenopancreatectomy.In all patients stents could be removed during the operation without difficulties.CONCLUSION:Despite the higher costs of these devices,fully covered self-expanding metal stents may be suitable to relief biliary obstruction due to bile duct stenosis,regardless of the underlying cause.CSEMS may also represent an effective treatment strategy of severe post-sphincterotomy bleeding,not controlled by other measures. | Ahmed Abdel Samie Stephan Dette Ulrich Vhringer Michael Stumpf Karolin Kopischke Lorenz Theilmann | 2012 | World Journal of Gastrointestinal Endoscopy2012，4，9： | 5 |

| 5 | A flexible protruding microelectrode array for neural interfacing in bioelectronic medicine显示文摘Recording neural signals from delicate autonomic nerves is a challenging task that requires the development of a lowinvasive neural interface with highly selective,micrometer-sized electrodes.This paper reports on the development of a three-dimensional(3D)protruding thin-film microelectrode array(MEA),which is intended to be used for recording low-amplitude neural signals from pelvic nervous structures by penetrating the nerves transversely to reduce the distance to the axons.Cylindrical gold pillars(O 20 or 50μm,~60μm height)were fabricated on a micromachined polyimide substrate in an electroplating process.Their sidewalls were insulated with parylene C,and their tips were optionally modified by wet etching and/or the application of a titanium nitride(TiN)coating.The microelectrodes modified by these combined techniques exhibited low impedances(~7 kΩ at 1 kHz for ∅ 50μm microelectrode with the exposed surface area of~5000μm^(2))and low intrinsic noise levels.Their functionalities were evaluated in an ex vivo pilot study with mouse retinae,in which spontaneous neuronal spikes were recorded with amplitudes of up to 66μV.This novel process strategy for fabricating flexible,3D neural interfaces with low-impedance microelectrodes has the potential to selectively record neural signals from not only delicate structures such as retinal cells but also autonomic nerves with improved signal quality to study neural circuits and develop stimulation strategies in bioelectronic medicine,e.g.,for the control of vital digestive functions. | Helen Steins Michael Mierzejewski Lisa Brauns Angelika Stumpf Alina Kohler Gerhard Heusel Andrea Corna Thoralf Herrmann Peter D.Jones Günther Zeck Rene von Metzen Thomas Stieglitz | 2022 | Microsystems & Nanoengineering2022，8，6： | 0 |
| 6 | 论创意竞赛作为应用型教学的一种方法显示文摘介绍并阐述了创意竞赛作为一种应用型教学活动的原理和实施。相互竞争的学生团队要分析一个合作企业遇到的在IT领域应用方面的问题,并制定解决方案。竞赛的目的是提升学生的专业能力、方法运用能力和社会能力。在设计教学/学习方案时采用了布鲁姆的分类法和设计思维法。本文介绍了三个不同的实施方案,最后总结了教师、学生和合作企业的经验,从而为以后进行创意竞赛提供了实施建议。 | Kurt Freudenthaler Rainer GroB Peter Rausch Wolfgang Renninger Michael Stumpf 陈颖 | 2018 | 应用型高等教育研究2018，3，3： | 0 |
