| 1 | Recent advances in endovascular techniques for management of acute nonvariceal upper gastrointestinal bleeding显示文摘Over the past two decades,transcatheter arterial embolization has become the first-line therapy for the management of upper gastrointestinal bleeding that is refractory to endoscopic hemostasis.Advances in catheter-based techniques and newer embolic agents, as well as recognition of the effectiveness of minimally invasive treatment options,have expanded the role of interventional radiology in the management of hemorrhage for a variety of indications,such as peptic ulcerbleeding,malignant disease,hemorrhagic Dieulafoy lesions and iatrogenic or trauma bleeding.Transcatheter interventions include the following:selective embolization of the feeding artery,sandwich coil occlusion of the gastroduodenal artery,blind or empiric embolization of the supposed bleeding vessel based on endoscopic findings and coil pseudoaneurysm or aneurysm embolization by three-dimensional sac packing with preservation of the parent artery.Transcatheter embolization is a fast,safe and effective,minimally invasive alternative to surgery when endoscopic treatment fails to control bleeding from the upper gastrointestinal tract.This article reviews the various transcatheter endovascular techniques and devices that are used in a variety of clinical scenarios for the management of hemorrhagic gastrointestinal emergencies. | Romaric F Loffroy Basem A Abualsaud Ming D Lin Pramod P Rao | 2011 | World Journal of Gastrointestinal Surgery2011，3，7： | 28 |
| 2 | Survival and outcomes for co-infection of chronic hepatitis C with and without cirrhosis and COVID-19: A multicenter retrospective study显示文摘BACKGROUND Chronic liver disease,particularly cirrhosis,is associated with worse outcomes in patients infected with coronavirus disease 2019(COVID-19).AIM To assess outcomes of COVID-19 infection among patients with pre-existing hepatitis C with or without liver cirrhosis.METHODS This multicenter,retrospective cohort study included all cases of confirmed coinfection of severe acute respiratory syndrome coronavirus 2 and chronic hepatitis C with or without liver cirrhosis who were admitted to six hospitals(Al-Sahel Hospital,Al-Matareya Hospital,Al-Ahrar Hospital,Ahmed Maher Teaching Hospital,Al-Gomhoreya Hospital,and the National Hepatology and Tropical Medicine Research Institute)affiliated with the General Organization for Teaching Hospitals and Institutes in Egypt.Patients were recruited from May 1,2020,to July 31,2020.Demographic,laboratory,imaging features,and outcomes were collected.Multivariate regression analysis was performed to detect factors affecting mortality.RESULTS This retrospective cohort study included 125 patients with chronic hepatitis C and COVID-19 co-infection,of which 64(51.20%)had liver cirrhosis and 40(32.00%)died.Fever,cough,dyspnea,and fatigue were the most frequent symptoms in patients with liver cirrhosis.Cough,sore throat,fatigue,myalgia,and diarrhea were significantly more common in patients with liver cirrhosis than in noncirrhotic patients.There was no difference between patients with and without cirrhosis regarding comorbidities.Fifteen patients(23.40%)with liver cirrhosis presented with hepatic encephalopathy.Patients with liver cirrhosis were more likely than non-cirrhotic patients to have combined ground-glass opacities and consolidations in CT chest scans:28(43.75%)vs 4(6.55%),respectively(P value<0.001).These patients also were more likely to have severe COVID-19 infection,compared to patients without liver cirrhosis:29(45.31%)vs 11(18.04%),respectively(P value<0.003).Mortality was higher in patients with liver cirrhosis,compared to those with no cirrhosis:33(51.56%)vs 9(14.75%),respectively(P value<0.001).All patients in Child-Pugh class A recovered and were discharged.Cirrhotic mortality occurred among decompensated patients only.A multivariate regression analysis revealed the following independent factors affecting mortality:Male gender(OR 7.17,95%CI:2.19–23.51;P value=0.001),diabetes mellitus(OR 4.03,95%CI:1.49–10.91;P value=0.006),and liver cirrhosis(OR 1.103,95%CI:1.037–1.282;P value<0.0001).We found no differences in liver function,COVID-19 disease severity,or outcomes between patients who previously received direct-acting antiviral therapy(and achieved sustained virological response)and patients who did not receive this therapy.CONCLUSION Patients with liver cirrhosis are susceptible to higher severity and mortality if infected with COVID-19.Male gender,diabetes mellitus,and liver cirrhosis are independent factors associated with increased mortality risk. | Shimaa Afify Basem Eysa Fatma Abdel Hamid Omnia M Abo-Elazm Mohamed A Edris Rabab Maher Ahmed Abdelhalim Muhammad Mostafa Abdel Ghaffar Dalia A Omran Hend Ibrahim Shousha | 2021 | World Journal of Gastroenterology2021，27，42： | 2 |
| 3 | 大西洋中脊26°S热液区玄武岩地球化学特征及其地幔源区性质显示文摘南大西洋中脊(SMAR)属于慢速扩张脊,26°S(SMAR 26°S)热液区是中国新近发现的以玄武岩为基岩的热液区。本次研究对热液区的玄武岩开展了岩相学和地球化学研究,揭示玄武岩的地球化学特征和岩浆源区性质,探讨其成矿潜力。结果表明,该热液区玄武岩地球化学特征和正常洋中脊玄武岩(N-MORB)相似,为钠质拉斑玄武岩;它们是由下伏亏损的尖晶石二辉橄榄岩地幔部分熔融而成。玄武岩所具有的低w(K2O)(0.05%~0.25%)、低(Ce/Yb)N比值(0.62~0.86),以及异常指数(Nb^*<1,P^*<1,Sr^*≤1,Zr^*>1)特征,表明源区地幔性质不均一,且受到了不同程度的陆壳物质混染;w(MgO)为7.52%~8.81%,指示热液区岩浆结晶分异程度低,岩浆演化不彻底。轻微的Eu正异常(δEu值为1.03~1.15),指示玄武岩形成过程中受到一定程度高温热液流体的影响,并处于强还原环境。与其他热液区玄武岩相比,研究区玄武岩Ba,Rb等高度不相容元素含量较低,均显示正Eu异常,岩石-海水相互作用弱。研究区玄武岩的Zn和Cu的含量分别为72.0~148.0×10^-6和79.9~138.5×10^-6,与MARK区和大西洋46°~32°S热液区玄武岩相比,研究区玄武岩可能具有更大的成矿潜力。 | 范蕾 王国芝 石学法 杨耀民 Holzheid Astrid Zoheir Basem A | 2020 | 矿物岩石2020，40，1： | 2 |

| 10 | Simple approach for the histomolecular diagnosis of central nervous system gliomas based on 2021 World Health Organization Classification显示文摘The classification of central nervous system(CNS)glioma went through a sequence of developments,between 2006 and 2021,started with only histological approach then has been aided with a major emphasis on molecular signatures in the 4^(th) and 5^(th) editions of the World Health Organization(WHO).The recent reformation in the 5th edition of the WHO classification has focused more on the molecularly defined entities with better characterized natural histories as well as new tumor types and subtypes in the adult and pediatric populations.These new subclassified entities have been incorporated in the 5^(th) edition after the continuous exploration of new genomic,epigenomic and transcriptomic discovery.Indeed,the current guidelines of 2021 WHO classification of CNS tumors and European Association of Neuro-Oncology(EANO)exploited the molecular signatures in the diagnostic approach of CNS gliomas.Our current review presents a practical diagnostic approach for diffuse CNS gliomas and circumscribed astrocytomas using histomolecular criteria adopted by the recent WHO classification.We also describe the treatment strategies for these tumors based on EANO guidelines. | Maher Kurdi Rana H Moshref Yousef Katib Eyad Faizo Ahmed A Najjar Basem Bahakeem Ahmed KBamaga | 2022 | World Journal of Clinical Oncology2022，13，7： | 0 |
