Preoperative MR examinations of 55 PanNEN patients (29 men, 26 women; mean age of 57.6 years, range 21-83 years) performed between June 2013 and December 2015 were reviewed. Qualitative and quantitative features were compared between tumor grades and stages determined by histopathological analysis.RESULTSIll defined margins were more common in G2-3 and stage III-IV PanNENs than in G1 and low-stage tumors (P < 0.001); this feature had high specificity in the identification of G2-3 and stage III-IV tumors (90.3% and 96%, 95%CI: 73.1-97.5 and 77.7-99.8). The mean apparent diffusion coefficient value was significantly lower in G2-3 and stage III-IV lesions compared to well differentiated and low-stage tumors (1.09 × 10<sup>-3</sup> mm<sup>2</sup>/s vs 1.45 × 10<sup>-3</sup> mm<sup>2</sup>/s and 1.10 × 10<sup>-3</sup> mm<sup>2</sup>/s vs 1.53 × 10<sup>-3</sup> mm<sup>2</sup>/s, P = 0.003 and 0.001). Receiving operator characteristic analysis determined optimal cut-offs of 1.21 and 1.28 × 10<sup>-3</sup> mm<sup>2</sup>/s for the identification of G2-3 and stage III-IV tumors, with sensitivity and specificity values of 70.8/80.7% and 64.5/64% (95%CI: 48.7-86.6/60-92.7 and 45.4-80.2/42.6-81.3).CONCLUSIONMR features of PanNENs vary according to their grade of differentiation and their stage at diagnosis and could predict the biological behavior of these tumors.展开更多

Application Procedure of 2010 World FairOn May 2, 2001, China, the first country, submitted formally an application for holding 2010 Shanghai World Fair to theBureau of International Exhibition (BIE). There were China, Russia, ROK, Poland, Mexico and Argentina (Afterwards ArgentinaWithdrew) formally submitting applications. The deadline for application is six months after the application was formally submittedby the first country. Then BIE sent investigation delegation to investigate various countries that made applications, and submittedreports to the Executive Commission and General Assembly. China stated reports at BIE 129th, 130th and 131st General Assembliesin June and November 2001 and July 2002 respectively. In December 2002, China stated the last report at BIE 132nd GeneralAssembly.展开更多

The results indicate that a trend with amplitude of 1.0 is a dominant component for the AOD variability in the recent decade. During the World Expo 2010, the average AOD level reduced 30% in comparison to the long-term trend. Two dominant annual components decreased 80% and 100%. This implies that the air quality in Shanghai was remarkably improved, and environmental initiatives and comprehensive actions for effective. AOD and API reducing air pollution are variability analysis results indicate that semi-annual and annual signals are dominant components implying that the monsoon weather is a dominant factor in modulating the AOD and API variability. The variability of AOD and API in selected districts located in both downtown and suburban areas shows similar trends; i.e., in 2000 the AOD began a monotonic increase, reached the maxima around 2006, then monotonically decreased to 2011 and from around 2006 the API started to decrease till 2011. This indicates that the air quality in the entire Shanghai area, whether urban or suburban areas, has remarkably been improved. The AOD improved degrees (IDS) in all the selected districts are (8.6±1.9)%, and API IDS are (9.2±7.1)%, ranging from a minimum value of 1.5% for Putuo District to a maximum value of 22% for Xuhui District.展开更多
