1焦炭特性及其在高炉下部的变化过程显示文摘气化、石墨化和溶解是影响焦炭从高炉软熔带至炉缸间行为的三个主要过程。过去几年在一些专题项目中对这些过程进行了研究。简要叙述并讨论了这些过程的相互作用及其与焦炭特性的关系。对焦炭的气化反应进行了实验室测试研究,用以评价高炉条件下焦炭的特性。用高炉条件下的气化测试装置测试了几种焦炭试样,考查的质量指标包括反应性、结构变化和强度等。用实际尺寸的焦炭块对块状焦炭试样的高温行为进行了评估,将不同种类的焦炭试样加热到2 000℃,以鉴别其在高温下的行为。高温下焦炭将发生石墨化,对高温反应后的强度进行了评定,并作了显微观察,发现了一些现象和组织结构的变化。焦炭与液态渣铁相互作用的研究结果对焦炭在高炉下部的行为有了更好的理解。通过试验研究了焦炭抗液态铁水溶解的性能,对入炉前的焦炭和经高温反应的焦炭分别进行了试验。分析讨论了焦炭的抗气化、抗石墨化和抗铁水溶解性能与其结构、化学成分和强度的关系。B van der Velden C J Atkinson T Bakker J R H Stuurwold G J Tijhuis 徐万仁 2014世界钢铁2014,,2:11
2Cystic lymphangioma of the pancreas显示文摘Lymphangioma of the pancreas is an extremely rare benign tumour of lymphatic origin,with fewer than 60 published cases. Histologically,it is polycystic,with the cysts separated by thin septa and lined with endothelial cells. Though congenital,it can affect all age groups,and occurs more frequently in females. Patients usually present with epigastric pain and an associated palpable mass. Complete excision is curative,even though,depending on the tumour location,surgery may be simple or involve extensive pancreatic resection and anastomoses. The authors present a 49-year-old woman in whom a polycystic septated mass,35 mm x 35 mm in size,was discovered by ultrasonography (US) in the body of the pancreas during investigations for epigastric pain and nausea. At surgery,a well circumscribed polycystic tumor was completely excised,with preservation of the pancreatic duct. The postoperative recovery was uneventful. Histology confirmed a microcystic lymphangioma of the pancreas. Immunohistochemistry showed cystic endothelial cells reactivity to factor Ⅷ -RA (++),CD31 (+++) and CD34 (-). Postoperatively,abdominal pain disappeared and the patient remained symptomfree for 12 mo until now. Although extremely rare,lymphangioma of the pancreas should be taken into consideration as a differential diagnosis of a pancreatic cystic lesion,especially in women.Radoje B Colovic Nikica M Grubor Marjan T Micev Henry Dushan E Atkinson Vitomir I Rankovic Mihajlo M Jagodic 2008World Journal of Gastroenterology2008,14,44:6
3Perigastric extraskeletal Ewing's sarcoma: A case report显示文摘Ewing's sarcoma (ES) is a neoplasm of undifferentiated small round cells, which occurs in the bones and deep soft tissues of children and adolescents. We present a rare case of a 44-year-old woman with gastric ES presenting with epigastric pain and weight loss. Ultrasound and computed tomography scans indicated a solid/cystic mass in the pancreatic tail. At laparotomy, the tumor was found attached to the posterior surface of the stomach, completely free from the pancreas, with no lymphadenopathy or local metastases. The polynodal, partly pseudocystic, dark-red soft tumor was excised. Histopathology revealed an anaplastic small-round-cell tumor with strong membranous CD99 immunoexpression. Additionally, there was patchy immunostaining for S-100 protein, vimentin, protein gene product (PGP) 9.5 and neuron-specifi c enolase, and weak focal CD117 cytoplasmic immunoreactivity. The patient had no adjuvant chemotherapy; her postoperative recovery was uneventful, and she remains symptom-free, and without any sign of recurrence at 20 mo. To the best of our knowledge, this is only the third ever case of gastric ES.Radoje B Colovic Nikica M Grubor Marjan T Micev Slavko V Matic Henry Dushan Edward Atkinson Stojan M Latincic 2009World Journal of Gastroenterology2009,15,2:2

12Two synchronous somatostatinomas of the duodenum and pancreatic head in one patient显示文摘Somatostatinomas are extremely rare neuroendocrine tumors of the gastrointestinal tract,f irst described in the pancreas in 1977 and in the duodenum in 1979.They may be functional and cause somatostatinoma or inhibi-tory syndrome,but more frequently are non-functioning pancreatic endocrine tumors that produce somatostatin alone.They are usually single,malignant,large lesions,frequently associated with metastases,and generally with poor prognosis.We present the unique case of a 57-year-old woman with two synchronous non-function-ing somatostatinomas,one solid duodenal lesion and one cystic lesion within the head of the pancreas,that were successfully resected with a pylorus-preserving Whipple's procedure.No secondaries were found in the liver,or in any of the removed regional lymph nodes.The patient had an uneventful recovery,and remains well and symptom-free at 18 mo postoperatively.This is an extremely rare case of a patient with two synchro-nous somatostatinomas of the duodenum and the pancreas.The condition is discussed with reference to the literature.Radoje B olovi Slavko V Mati Marjan T Micev Nikica M Grubor Henry Dushan Atkinson Stojan M Latini 2009World Journal of Gastroenterology2009,15,46:1
