| 1 | Unstable Head-Flow Characteristic Generation Mechanism of a Low Specific Speed Mixed Flow Pump显示文摘This paper treats the flow instabilities in a mixed flow pump with a vaned diffuser. Test pump has a positive slope of a head-flow performance curve at 65% flow rate of BEP (Best Efficiency Point) because of a rotating stall. Dynamic Particle Image Velocimetry (PIV) and pressure fluctuation measurements are used for investigating the propagation mechanism of a rotating stall. It was found that unstable performance was caused by periodical large scale abrupt backflow generated from the vaned diffuser to the outlet of impeller. Further, the relation between the static pressure at the inlet of diffuser vane and the internal flow condition was clarified. From these experimental results, in order to improve the positive slope of a head-flow performance curve, to suppress the growth of strong vortex toward the inlet of diffuser vane was proved to be a key point. | Masahiro MIYABE Hideaki MAEDA Isamu UMEKI Yoshinori JITTANI | 2006 | Journal of Thermal Science2006，15，2： | 53 |
| 2 | Diagnosis of IgG4-related sclerosing cholangitis显示文摘IgG4-related sclerosing cholangitis(IgG4-SC)is often associated with autoimmune pancreatitis.However,the diffuse cholangiographic abnormalities observed in IgG4-SC may resemble those observed in primary sclerosing cholangitis(PSC),and the presence of segmental stenosis suggests cholangiocarcinoma(CC).IgG4-SC responds well to steroid therapy,whereas PSC is only effectively treated with liver transplantation and CC requires surgical intervention.Since IgG4-SC was first described,it has become a third distinct clinical entity of sclerosing cholangitis.The aim of this review was to introduce the diagnostic methods for IgG4-SC.IgG4-SC should be carefully diagnosed based on a combination of characteristic clinical,serological,morphological,and histopathological features after cholangiographic classification and targeting of a disease for differential diagnosis.When intrapancreatic stenosis is detected,pancreatic cancer or CC should be ruled out.If multiple intrahepatic stenoses are evident,PSC should be distinguished on the basis of cholangiographic findings and liver biopsy with IgG4 immunostaining.Associated inflammatory bowel disease is suggestive of PSC.If stenosis is demonstrated in the hepatic hilar region,CC should be discriminated by ultrasonography,intraductal ultrasonography,bile duct biopsy,and a higher cutoff serum IgG4 level of 182 mg/dL. | Takahiro Nakazawa Itaru Naitoh Kazuki Hayashi Katsuyuki Miyabe Shuya Simizu Takashi Joh | 2013 | World Journal of Gastroenterology2013，19，43： | 20 |
| 3 | Inflammatory bowel disease of primary sclerosing cholangitis:A distinct entity?显示文摘This is a review of the characteristic findings of inflammatory bowel disease(IBD)associated with primary sclerosing cholangitis(PSC)and their usefulness in the diagnosis of sclerosing cholangitis.PSC is a chronic inflammatory disease characterized by idiopathic fibrous obstruction and is frequently associated with IBD.IBDassociated with PSC(PSC-IBD)shows an increased incidence of pancolitis,mild symptoms,and colorectal malignancy.Although an increased incidence of pancolitis is a characteristic finding,some cases are endoscopically diagnosed as right-sided ulcerative colitis.Pathological studies have revealed that inflammation occurs more frequently in the right colon than the left colon.The frequency of rectal sparing and backwash ileitis should be investigated in a future study based on the same definition.The cholangiographic findings of immunoglobulin G4-related sclerosing cholangitis(IgG4-SC)are similar to those of PSC.The rare association between IBD and IgG4-SC and the unique characteristics of PSC-IBD are useful findings for distinguishing PSC from IgG4-SC. | Takahiro Nakazawa Itaru Naitoh Kazuki Hayashi Hitoshi Sano Katsuyuki Miyabe Shuya Shimizu Takashi Joh | 2014 | World Journal of Gastroenterology2014，20，12： | 6 |
