ABSTRACT
Objective@#To investigate the atypical computed tomography (CT) features of primary small intestinal lymphoma (PSIL), and its correlation with pathology.@*Methods@#From July 2007 to June 2018, at Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, the clinical features and CT imaging data of 29 histopathologically diagnosed PSIL with atypical CT features were retrospectively analyzed.@*Results@#A total of 29 cases were all confirmed as Non-Hodgkin′s lymphoma including 23 cases of B cell lymphoma and six cases of peripheral T cell lymphoma. In 24 PSIL patients, the intestinal wall was unevenly thickened. While five cases had intra- and extra-intestinal masses. Images of four PSIL patients showed heterogeneous density at unenhanced CT scan, five cases presented with heterogeneous mild to moderate enhancement and five cases demonstrated with obvious enhancement at portal venous phase. Multiple ulcers in mucosa were found in 20 cases, and obviously abnormal mucosal enhancement was found in five cases, and 13 cases showed rough serosa layer of intestinal wall and the fat gap around the intestinal wall disappeared. Adjacent organs were involved in four cases and intestinal obstruction occurred in eight cases.@*Conclusion@#The atypical imaging of PSIL can be heterogeneous density of the lesion, heterogeneous or obvious enhancement at enhanced scan, multiple ulcers on the mucosal surface, thickening of the mucosal surface, blurred peripheral fat space, involvement of adjacent organs and intestinal obstruction.

ABSTRACT
Autoimmune pancreatitis (AIP) is a special autoimmune-mediated pancreatitis with the clinical manifestation of obstructive jaundice, and it often has good response to steroids. At present, AIP is classified into type 1 and type 2. The imaging findings of AIP include diffuse or localized pancreatic parenchymal enlargement, and the former is also called the “sausage-shaped” appearance. Imaging examinations of AIP have their own advantages and disadvantages. Ultrasound, endoscopic retrograde cholangiopancreatography, endoscopic ultrasound, computed tomography, magnetic resonance imaging, PET-CT, and PET-MR help with diagnosis and differential diagnosis and can be used for the monitoring and follow-up of clinical outcomes.
ABSTRACT
Objective To investigate the formation of biofilm in clinical isolates of Staphylococcus epidermidis ,and to analyse the correlation between biofilm formation and antibacterial resistance of Staphylococcus epidermidis .Methods A total of 62 strains of Staphylococcus epidermidis isolated from blood specimens of inpatients with bloodstream infection ,from January 2014 to February 2015 ,were collected .The biofilm formation of Staphylococcus epidermidis was detected by using the semi‐quantitative adherence as‐say and polymerase chain reaction(PCR) amplification experiment .The antibacterial susceptibility test was carried out according to K‐B method .Results The positive rate of biofilm formation detected by using the semi‐quantitative adherence assay and PCR for icaA gene were 37 .1% (23 strains) and 43 .5% (27 strains) respectively ,and there was no statistically significant difference(P>0 .05) .There were 14 positive strains detected by both methods .The resistance rates of strains producing biofilm to antibacterial a‐gents were generally higher than those of non‐producing biofilm strains ,and there were statistically significant differences in resist‐ance rates of strains to gentamicin ,penicillin ,oxacillin ,levofloxacin and cefoxitin(P<0 .05) .All bacteria were sensitive to vancomy‐cin ,linezolid and quinupristin/dalfopristin .Conclusion There is no significant difference between the two methods in detecing bio‐film formation .The resistance rates of strains producing biofilm to antibacterial agents were generally higher than those of non‐pro‐ducing biofilm strains .
ABSTRACT
Third party custody system at the Second Affiliated Hospital ot Zhejiang University has reduced hospital costs,raised efficiency and optimized resources.The standardized management system featuring 5S+ 1 achieved such outcomes as +5 and -5,and 0 inventory.A three-year review of the economic performance at the hospital has saved three million yuan of costs,proving that the system can help build an effective material supply system for contemporary general hospitals.
