ABSTRACT Einleitung: In einer retrospektiven Analyse untersuchten wir die Anwendung der Proteinführungssonde nach Ermisch bei Ileuspatienten. Methoden: Insgesamt 288 klinikinterne Fälle aus dem Zeitraum 2000 bis 2010 wurden zum Thema „Ileusoperation mit versus ohne Ermischsonde“ analysiert. Alle Patienten mit erfolgreicher Sondenplatzierung wurden der Gruppe 1 zugeordnet (n=102). Fälle ohne Sondentherapie bildeten die Gruppe 2. Ergebnisse: Im Patientenkollektiv (n=288) lag das Durchschnittsalter bei 66,8 (±17,7) Jahren. 51,7% waren weiblich. Eine Ileusvoroperation betraf in Gruppe 1 12,7%, in Gruppe 2 6,5% (p=0,081,n.s.). Die Dünndarmeröffnung erfolgte in Gruppe 1 bei 27,3%, in Gruppe 2 bei 72,7% (p=0,001). Ein paralytischer Ileus lag in Gruppe 1 bei 15,7% und in Gruppe 2 bei 5,4% vor (p=0,001). Als postoperativ paralytischen Ileus wurden in Gruppe 1 5,9%(6/102), in Gruppe 2 3,8%(7/186) identifiziert (n.s.). In 5% der Fälle aus Gruppe 1 handelte es sich um ein Ileusfrührezidiv (vs. 1,1% in Gruppe 2; n.s.). 28 (80%) der 34 Reileus-Fälle traten in Gruppe 2 auf (Gr. 1: n=7, 20%; p=0,022). Die Letalität aufgrund postoperativer Sepsis (S) und Peritonitis (P) lag bei 24,1% (S) und 28,6% (P) in Gruppe 1 versus 65,4%(S) und 47,6%(P) in Gruppe 2 ( p(S)=0,003=s.; p(P)=0,31=n.s.). Postoperatives Multiorganversagen (ngesamt=20/288) betraf 5 Patienten (4,9%) der Gruppe 1 versus 15 Patienten (8,1%) in Gruppe 2 (n.s.). In 5,9% der 102 untersuchten Fälle kam es zu sondenspezifischen Majorkomplikationen. Die postoperative Letalität lag hingegen in Gruppe 1 bei 16,7% und in Gruppe 2 bei 18,3% (n.s.). Schlussfolgerung: Die Ermischsonde stellt vor allem beim postoperativ paralytischen Ileus (insbes. Ileusfrührezidiv), aber auch bei fortgeschrittenen mechanischen Ileusformen ein effektives Instrument zur geschlossenen Sekretausleitung und postoperativen Dünndarmschienung dar. Bei rein vaskulären Ileusformen bzw. im akuten Schub einer chronisch entzündlichen Darmerkrankung ist das Verfahren häufiger mit Risiken verbunden.

The success in fabrication of Cr-doped fibers (CDFs) with fluorescence of Cr3+ by powder-in-tube (PIT) method equipped with drawing-tower process is demonstrated. However, the fabrication by using powder-in-tube (PIT) with redrawing technique provides a better solution to improve the concentration of Cr-ion to enhance the fluorescence of CDFs. The Cr-doped powder was composed of CaO-Al2O3-BaCO3-MgO-Cr2O3 as the material of core. The CDFs had a 7 £gm core and a 125 £gm cladding. The transmission loss was 0.27 dB/cm at 1550 nm and a core non-circularity of less than 3% for the CDFs are achieved. The fluorescence intensity of Cr3+ between 800~1200 nm was 6 nW/nm. The optical fiber fabrication processes, whether the preform is made by MCVD(Modified Chemical Vapor Deposition), RIT(Rod-in-Tube) or PIT, the inter-diffusion between core and cladding materials is an inevitable issue at such high fiber drawing temperature. Since SiO2 is amajor component in the cladding, SiO2 will certainly diffuse into the core region and become one of the new constituents in the core. The Cr-doped powder was composed of SiO2- Al2O3-MgO-K2O-TiO2-Cr2O3 as the material of core. The CDFs had a 10 £gm core and a 125 £gm cladding. The fluorescence intensity of Cr4+ between 900~1300 nm was 200 pW/nm. The CDFs were successfully fabricated by using podwer-in-tube with redrawing technique. The demonstration of CDFs makes it possible as a new generation broadband fiber amplifier and a broadband source for high resolution OCT.

The objective of this study is to design and manufacture a tube hydroforming test machine with axial feeding, which includes a forming apparatus¡Bhydraulic system and control system. Using feedback control and fuzzy control criterion to conduct T-Shape hydraulic bulging experiments. Using annealed AA6063-T5 aluminum alloy tubes, experiments are carried out with different working path and different feeding distance, analyze the influences of these parameters on the formability of the tubes.

In recent years the economical booming change was fast, last year at the beginning of the whole world was also in the currency expansion concealed worry, in the second half of the year transformed the global deflation rapidly, the original material price fell over 70% by the peak, the domestic electronic spare-time university had the unpaid holiday, the unemployment rate surges upward. But the government will expand the domestic demand continually, the steel and iron price stops by most recent several year high spot rapid reverse to the near future falls returns to stability, lets building industry have the superiority in the cost. Generally in the tradition the fire water pipe road mostly uses the galvanization steel pipe, the price fluctuations and in the construction process must use the welding or Che Ya greatly processes, also in the transporting is not convenient, meets great caliber Shi Zuoshi must rely the crane to assist to transport. In recent years American raw material business developed 'the fire protection rank chlorination polyvinyl-chloride (CPVC)' the product, utilized in the fire tubing domain, substituted for the steel pipe product gradually. This research namely aims at this product discussion domestic building industry to the CPVC product understanding degree and the purchase wish, and further provides for the CPVC product business agent takes the marketing reference the basis. The findings discovered that a domestic product was still strange regarding this, although the fire prevention Controlling organization has checked one of for fire aqueous system tubing materials, but city occupying rate and the steel pipe product comparison are not as before high.
