| 2 | Hepatocellular carcinoma: From diagnosis to treatment显示文摘Hepatocellular carcinoma(HCC) is the sixth most prevalent malignancy worldwide and is a rising cause of cancer related mortality. Risk factors for HCC are well documented and effective surveillance and early diagnosis allow for curative therapies. The majority of HCC appears to be caused by cirrhosis from chronic hepatitis B and hepatitis C virus. Preventive strategies include vaccination programs and anti-viral treatments.Surveillance with ultrasonography detects early stage disease and improves survival rates. Many treatment options exist for individuals with HCC and are determined by stage of presentation. Liver transplantation is offered to patients who are within the Milan criteria and are not candidates for hepatic resection. In patients with advanced stage disease, sorafenib shows some survival benefit. | Abhijeet Waghray Arvind R Murali KV Narayanan Menon | 2015 | World Journal of Hepatology2015,7,8: | 27 |

| 4 | 机械化学法制备的Al/Ce复合氧化物负载NiMo催化剂的加氢脱硫活性(英文)显示文摘将Al和/或Ce的硝酸盐与NH_4HCO_3球磨混合,采用机械化学法制备了Al_2O_3-CeO_2载体(其中Ce含量为1-10 wt%),再以杂多钼酸盐(NH_4)_4NiMo_6O_(24)为活性金属Ni和Mo的前驱体,通过浸渍法制备NiMo_6/Al_2O_3-CeO_2催化剂,并将其用于1-苯并噻吩(BT)的加氢脱硫(HDS)反应中.运用化学分析、X射线衍射、N_2吸附-脱附法、H_2程序升温还原、NH_3程序升温脱附和X射线光电子能谱对催化剂的物化性质进行了表征.结果表明,催化剂的酸性随着载体中Ce含量的增加而下降.Ce修饰的Al_2O_3载体表面的NiS/MoS原子比下降了2倍.NiMo_6/Al_2O_3催化剂表现出最高的HDS活性(以单位重量催化剂计),其酸性和表面MoO_xS_y物种的浓度(Mo^(5+)浓度)也最高;当催化剂中Ce含量逐渐增加到10 wt%以上时,其活性逐渐将为0.与浸渍法制得的参比催化剂相比,前驱体和催化剂组成相同的情况下,采用机械化学法制得的所有催化剂活性明显提高. | Květa Jirátová Alla Spojakina Luděk Kaluza Radostina Palcheva Jana Balabánová Georgi Tyuliev | 2016 | Chinese Journal of Catalysis2016,37,2: | 6 |
| 5 | 镍钼杂多酸制备NiMo/γ-Al_2O_3催化剂及硼、钴或镍改性氧化铝的影响(英文)显示文摘A hydrotreating NiMo/γ-Al2O3 catalyst(12 wt% Mo and 1.1 wt% Ni) was prepared by impregnation of the support with the Anderson-type heteropolyoxomolybdate(NH4)4Ni(OH)6Mo6O18.Before impregnation of the support,it was modified with an aqueous solution of H3BO3,Co(NO3)2,or Ni(NO3)2.The catalysts were investigated using N2 adsorption,O2 chemisorption,X-ray diffraction,UV-Vis spectroscopy,Fourier transform infrared spectroscopy,temperature-programmed reduction,temperature-programmed desorption,and X-ray photoelectron spectroscopy.The addition of Co,Ni,or B influenced the Al2O3 phase composition and gave increased catalytic activity for 1-benzothiophene hydrodesulfurization(HDS).X-ray photoelectron spectroscopy confirmed that the prior loading of Ni,Co or B increased the degree of sulfidation of the NiMo/γ-Al2O3 catalysts.The highest HDS activity was observed with the NiMo/γ-Al2O3 catalyst with prior loaded Ni. | Radostina PALCHEVA Luděk KALUZA Alla SPOJAKINA Květue JIRTOV Georgi TYULIEV | 2012 | 催化学报2012,33,6: | 6 |
| 6 | Successful outcome following resection of a pancreatic liposarcoma with solitary metastasis显示文摘Liposarcomas are rare soft tissue tumors, commonly affecting the lower limbs and less commonly the retroperitoneum. Although other organs can be affected,the pancreas is one of the rarest, and metastasis at presentation has never been reported. We describe the case of a 76-year-old gentleman presenting with abdominal pain and an abdominal mass. Imaging confirmed a primary tumor in the body and tail of the pancreas, with a metastatic deposit in the mesentery adjacent to the second part of the duodenum. Biopsy confirmed a liposarcoma, and subsequently a complete surgical excision was achieved. He then received adjuvant radiotherapy and has remained disease free for the next 26 mo. | IM Dodo JA Adamthwaite P Jain A Roy PJ Guillou KV Menon | 2005 | World Journal of Gastroenterology2005,11,48: | 5 |

| 11 | 血清铁蛋白是非酒精性脂肪肝患者组织炎症严重程度和晚期肝纤维化的独立预测指标显示文摘非酒精性脂肪肝(nonalcoholicfattyliverdisease。NAFLD)是肝脏疾病最常见的病因.在美国人群中发病率可达20%。铁蛋白是肝脏储存铁的主要形式.原发性或继发性铁代谢紊乱都会增加肝脏铁蛋白的分泌.从而导致肝内和循环中铁蛋白水平的增加。研究表明.炎症刺激和氧化应激能上调血清铁蛋白(sel3.1mferriritin,SF)的表达,其作用可能是通过特殊的氧化剂作用于蛋白质转录和翻译阶段而实现的。 | Kowdley KV Belt P Wilson LA 罗光成 闫惠平 | 2013 | 北京医学2013,35,3: | 2 |
| 12 | Predominant mucosal expression of 5-HT_(4(+h)) receptor splice variants in pig stomach and colon显示文摘AIM: To investigate cellular 5-HT4(-h/+h) receptor distribution, particularly in the epithelial layer, by laser mi-crodissection and polymerase chain reaction (PCR) in porcine gastrointestinal (GI) tissues. METHODS: A stepwise approach was used to evaluate RNA quality and to study cell-specific 5-HT4 receptor mRNA expression in the porcine gastric fundus and colon descendens. After freezing, staining and laser microdissection and pressure catapulting (LMPC), RNA quality was evaluated by the Experion automated electrophoresis system. 5-HT4 receptor and glyceral-dehyde-3-phosphate dehydrogenase (GAPDH) expressions were examined by endpoint reverse transcription (RT)-PCR in mucosal and muscle-myenteric plexus (MMP) tissue fractions, in mucosal and MMP parts of hematoxylin and eosin (HE) stained tissue sections andin microdissected patches of the epithelial and circular smooth muscle cell layer in these sections. Pig gastric fundus tissue sections were also stained immunohisto-chemically (IHC) for enterochromaffin cells (EC cells; MAB352); these cells were isolated by LMPC and examined by endpoint RT-PCR. RESULTS: After HE staining, the epithelial and circular smooth muscle cell layer of pig colon descendens and the epithelial cell layer of gastric fundus were identified morphologically and isolated by LMPC. EC cells of pig gastric fundus were successfully stained by IHC and isolated by LMPC. Freezing, HE and IHC staining, and LMPC had no influence on RNA quality. 5-HT4 recep-tor and GAPDH mRNA expressions were detected in mucosa and MMP tissue fractions, and in mucosal and MMP parts of HE stained tissue sections of pig colon descendens and gastric fundus. In the mucosa tissue fractions of both GI regions, the expression of h-exon containing receptor [5-HT4(+h) receptor] mRNA was significantly higher (P<0.01) compared to 5-HT4(-h) re-ceptor expression, and a similar trend was obtained in the mucosal part of HE stained tissue sections. Large microdissected patches of the epithelial and circular smooth muscle cell layer of pig colon descendens and of the epithelial cell layer of pig gastric fundus, also showed 5-HT4 receptor and GAPDH mRNA expression. No 5-HT4 receptor mRNA expression was detected in gastric LMPC-isolated EC cells from IHC stained tissues, which cells were positive for GAPDH. CONCLUSION: Porcine GI mucosa predominantly expresses 5-HT4(+h) receptor splice variants, suggesting their contribution to the 5-HT4 receptor-mediated mu-cosal effects of 5-HT. | Evelien KV Priem Joris H De Maeyer Mado Vandewoestyne Dieter Deforce Romain A Lefebvre | 2013 | World Journal of Gastroenterology2013,19,24: | 2 |
