| 1 | Pancreatic metastases from renal cell carcinoma:The state of the art显示文摘Pancreatic metastases are rare,with a reported incidence varying from 1.6%to 11%in autopsy studies of patients with advanced malignancy.In clinical series,the frequency of pancreatic metastases ranges from 2%to 5%of all pancreatic malignant tumors.However,the pancreas is an elective site for metastases from carcinoma of the kidney and this peculiarity has been reported by several studies.The epidemiology,clinical presentation,and treatment of pancreatic metastases from renal cell carcinoma are known from singleinstitution case reports and literature reviews.Thereis currently very limited experience with the surgical resection of isolated pancreatic metastasis,and the role of surgery in the management of these patients has not been clearly defined.In fact,for many years pancreatic resections were associated with high rates of morbidity and mortality,and metastatic disease to the pancreas was considered to be a terminal-stage condition.More recently,a significant reduction in the operative risk following major pancreatic surgery has been demonstrated,thus extending the indication for these operations to patients with metastatic disease. | Roberto Ballarin Mario Spaggiari Nicola Cautero Nicola De Ruvo Roberto Montalti Cristina Longo Anna Pecchi Patrizia Giacobazzi Giuseppina De Marco Giuseppe D’Amico Giorgio Enrico Gerunda Fabrizio Di Benedetto | 2011 | World Journal of Gastroenterology2011，17，43： | 21 |
| 2 | Post-transplantation hepatocellular carcinoma recurrence: Patterns and relation between vascularity and differentiation degree显示文摘AIM: To evaluate the relationship between hepatocellular carcinoma(HCC) vascularity and grade; to describe patterns and vascular/histopathological variations of post-transplantation recurrence.METHODS: This retrospective study included 165 patients(143 men, 22 women; median age 56.8 years, range 28-70.4 years) transplanted for HCC who had a follow-up period longer than 2 mo. Pre-transplantation dynamic computed tomography or magnetic resonance examinations were retrospectively reviewed, classifying HCC imaging enhancement pattern into hypervascular and hypovascular based on presence of wash-in during arterial phase. All pathologic reports of the explanted livers were reviewed, collecting data about HCC differentiation degree. The association between imaging vascular pattern and pathological grade was estimated using the Fisher exact test. All follow-up clinical and imaging data were reviewed for evidence of recurrence. Recurrence rate was calculated and imaging features of recurrent tumor were collected, classifying early and late recurrences based on timing(< or ≥ 2 years after transplantation) and intrahepatic, extrahepatic and both intrahepatic and extrahepatic recurrences based onlocation. All intrahepatic recurrences were classified as hypervascular or hypovascular and the differentiation degree was collected where available. The presence of variations in imaging enhancement pattern and pathological grade between the primary tumor and the intrahepatic recurrence was evaluated and the association between imaging and histopatholgical variations was estimated by using the χ2 test. RESULTS: Of the 163 patients with imaging evidence of viable tumor, 156(95.7%) had hypervascular and 7(4.3%) hypovascular HCC. Among the 125 patients with evidence of viable tumor in the explanted liver, 19(15.2%) had grade 1, 56(44.8%) grade 2, 40(32%) grade 3 and 4(3.2%) grade 4 HCC, while the differentiation degree was not assessable for 6 patients(4.8%). A significant association was found between imaging vascularity and pathological grade(P = 0.035). Post-transplantation recurrence rate was 14.55%(24/165). All recurrences occurred in patients who had a hypervascular primary tumor. Three patients(12.5%) experienced late recurrence; the location of the first recurrence was extrahepatic in 14 patients(58.3%), intrahepatic in 7 patients(29.2%) and both intrahepatic and extrahepatic in 3 patients(12.5%). Two patients had a variation in imaging characteristics between the primary HCC(hypervascular) and the intrahepatic recurrent HCC(hypovascular), while 1 patient had a variation of histopathological characteristics(from moderate to poor differentiation), however no association was found between imaging and histopathological variations.CONCLUSION: A correlation was found between HCC grade and vascularity; some degree of variability may exist between the primary and the recurrence imaging/histopathological characteristics, apparently not correlated. | Annarita Pecchi Giulia Besutti Mario De Santis Cinzia Del Giovane Sofia Nosseir Giuseppe Tarantino Fabrizio Di Benedetto Pietro Torricelli | 2015 | World Journal of Hepatology2015，7，2： | 5 |

| 8 | Ruthenium promotion of Co/SBA-15 catalysts for Fischer-Tropsch synthesis in slurry-phase reactors显示文摘The aim of this work was to evaluate the catalytic properties of a Ru promoted Co/SBA-15 catalyst for Fischer-Tropsch synthesis(FTS).The Ru promoted Co/SBA-15 catalyst was prepared by wet impregnation method and was characterized by X-ray diffraction,X-ray energy dispersion spectrophotometer,N2 adsorption-desorption,temperature-programmed reduction and transmission electron microscopy.The Fischer-Tropsch synthesis using the catalyst was carried out to evaluate the catalyst activity and its effect on FTS product distribution.The synthesis was carried out in a slurry reactor operating at 513 K,20 atm,CO:H2 molar ratio of 1:1.X-ray diffraction showed that the calcined cobalt catalyst did not modify the structure of SBA-15,proving that Co was present in the form of Co3O4 in the catalyst.The addition of cobalt in SBA-15 decreased the specific superficial area of the molecular sieve.Fischer-Tropsch synthesis activity and C5+hydrocarbon selectivity increased with the addition of Ru.The increases in activity and selectivity were attributed to the increased number of active sites resulting from higher reducibility and the synergetic effect of Ru and Co.Ru/Co/SBA-15 catalysts showed moderate conversion(40%)and high selectivity towards the production of C5+(80 wt%). | Jocielys Jovelino Rodrigues Gina Pecchi Fabiano AndrNarciso Fernandes Meiry Glucia Freire Rodrigues | 2012 | Journal of Natural Gas Chemistry2012，21，6： | 1 |
