| 1 | Role of interventional radiology in the management of acute gastrointestinal bleeding显示文摘Acute gastrointestinal bleeding(GIB) can lead to significant morbidity and mortality without appropriate treatment. There are numerous causes of acute GIB including but not limited to infection, vascular anomalies, inflammatory diseases, trauma, and malignancy. The diagnostic and therapeutic approach of GIB depends on its location, severity, and etiology. The role of interventional radiology becomes vital in patients whose GIB remains resistant to medical and endoscopic treatment. Radiology offers diagnostic imaging studies and endovascular therapeutic interventions that can be performed promptly and effectively with successful outcomes. Computed tomography angiography and nuclear scintigraphy can localize the source of bleeding and provide essential information for the interventional radiologist to guide therapeutic management with endovascular angiography and transcatheter embolization. This review article provides insight into the essential role of Interventional Radiology in the management of acute GIB. | Raja S Ramaswamy Hyung Won Choi Hans C Mouser Kazim H Narsinh Kevin C McCammack Tharintorn Treesit Thomas B Kinney | 2014 | World Journal of Radiology2014，6，4： | 8 |
| 2 | One hundred and seventy-eight consecutive pancreatoduodenectomies without mortality:role of the multidisciplinary approach显示文摘BACKGROUND:Pancreatoduodenectomy offers the only chance of cure for patients with periampullary cancers.This,however,is a major undertaking in most patients and is associated with a significant morbidity and mortality.A multidisciplinary approach to the workup and follow-up of patients undergoing pancreatoduodenectomy was initiated at our institution to improve the diagnosis,resection rate,mortality and morbidity.We undertook the study to assess the effect of this approach on diagnosis,resection rates and short-term outcomes such as morbidity and mortality.METHODS:A prospective database of patients presenting with periampullary cancers to a single surgeon between April 2004 and April 2010 was reviewed.All cases were discussed at a multidisciplinary meeting comprising surgeons,gastroenterologists,radiologists,oncologists,radiation oncologists,pathologists and nursing staff.A standardized investigation and management algorithm was followed.Complications were graded according to the Clavien-Dindo classification.RESULTS:A total of 295 patients with a periampullary lesion were discussed and 178 underwent pancreatoduodenectomy (resection rate 60%).Sixty-one patients (34%) required either a vascular or an additional organ resection.Eighty-nine patients experienced complications,of which the commonest was blood transfusion (12%).Thirty-four patients (19%) had major complications,i.e.grade 3 or above.There was no in-hospital,30-day or 60-day mortality.CONCLUSIONS:Pancreatoduodenectomy can safely be performed in high-volume centers with very low mortality.The surgeon's role should be careful patient selection,intensive preoperative investigations,use of a team approach,and an unbiased discussion at a multidisciplinary meeting to optimize the outcome in these patients. | Jaswinder S Samra Raul Alvarado Bachmann Julian Choi Anthony Gill Michael Neale Vikram Puttaswamy Cameron Bell Ian Norton Sarah Cho Steven Blome Ritchie Maher Sivakumar Gananadha Thomas J Hugh | 2011 | Hepatobiliary & Pancreatic Diseases International2011，10，4： | 8 |

| 4 | Enhanced second-harmonic generation from two-dimensional MoSe_(2) on a silicon waveguide显示文摘Two-dimensional transition-metal dichalcogenides(TMDCs)with intrinsically broken crystal inversion symmetry and large secondorder nonlinear responses have shown great promise for future nonlinear light sources.However,the sub-nanometer monolayer thickness of such materials limits the length of their nonlinear interaction with light.Here,we experimentally demonstrate the enhancement of the second-harmonic generation from monolayer MoSe_(2) by its integration onto a 220-nm-thick silicon waveguide.Such on-chip integration allows for a marked increase in the interaction length between the MoSe_(2) and the waveguide mode,further enabling phase matching of the nonlinear process.The demonstrated TMDC–silicon photonic hybrid integration opens the door to second-order nonlinear effects within the silicon photonic platform,including efficient frequency conversion,parametric amplification and the generation of entangled photon pairs. | Haitao Chen Vincent Corboliou Alexander S Solntsev Duk-Yong Choi Maria A Vincenti Domenico de Ceglia Costantino de Angelis Yuerui Lu Dragomir N Neshev | 2017 | Light(Science & Applications)2017，6，1： | 7 |
| 5 | 4-1BB signaling activates glucose and fatty acid metabolism to enhance CD8^(+) T cell proliferation显示文摘4-1BB(CD137)is a strong enhancer of the proliferation of CD8^(+)T cells.Since these cells require increased production of energy and biomass to support their proliferation,we hypothesized that 4-1BB signaling activated glucose and fatty acid metabolism.We found that treatment with agonistic anti-4-1BB mAb promoted the proliferation of CD8^(+)T cells in vitro,increasing their size and granularity.Studies with a glycolysis inhibitor and a fatty acid oxidation inhibitor revealed that CD8^(+)T cell proliferation required both glucose and fatty acid metabolism.Anti-4-1BB treatment increased glucose transporter 1 expression and activated the liver kinase B1(LKB1)-AMP-activated protein kinase(AMPK)-acetyl-CoA carboxylase(ACC)signaling pathway,which may be responsible for activating the metabolism of glucose and fatty acids.We also examined whether blocking glucose or fatty acid metabolism affected cell cycle progression and the anti-apoptotic effect of 4-1BB signaling.The increase of anti-apoptotic factors and cyclins in response to anti-4-1BB treatment was completely prevented by treating CD8^(+)T cells with the fatty acid oxidation inhibitor,etomoxir,but not with the glycolysis inhibitor,2-deoxy-D-glucose.We conclude that anti-4-1BB treatment activates glucose and fatty acid metabolism thus supporting the increased demand for energy and biomass,and that fatty acid metabolism plays a crucial role in enhancing the cell cycle progression of anti-CD3-activated CD8^(+)T cells in vitro and the anti-apoptotic effects of 4-1BB signaling on these cells. | Beom K Choi Do Y Lee Don G Lee Young H Kim Seon-Hee Kim Ho S Oh Chungyong Han Byoung S Kwon | 2017 | Cellular & Molecular Immunology2017，14，9： | 6 |
| 6 | Immunohistochemical expression of intrarenal renin angiotensin system components in response to tempol in rats fed a high salt diet显示文摘AIM To determine the effect of tempol in normal rats fed high salt on arterial pressure and the balance between antagonist components of the renal renin-angiotensin system.METHODS Sprague-Dawley rats were fed with 8% Na Cl highsalt(HS) or 0.4% Na Cl(normal-salt,NS) diet for 3 wk,with or without tempol(T)(1 mmol/L,administered in drinking water). Mean arterial pressure(MAP),glomerularfiltration rate(GFR),and urinary sodium excretion(UVNa) were measured. We evaluated angiotensin Ⅱ(Ang Ⅱ),angiotensin 1-7(Ang 1-7),angiotensin converting enzyme 2(ACE2),mas receptor(Mas R),angiotensin type 1 receptor(AT1R) and angiotensin type 2 receptor(AT2R) in renal tissues by immunohistochemistry.RESULTS The intake of high sodium produced a slight but significant increase in MAP and differentially regulated components of the renal renin-angiotensin system(RAS). This included an increase in Ang Ⅱ and AT1 R,and decrease in ACE-2 staining intensity using immunohistochemistry. Antioxidant supplementation with tempol increased natriuresis and GFR,prevented changes in blood pressure and reversed the imbalance of renal RAS components. This includes a decrease in Ang Ⅱ and AT1 R,as increase in AT2,ACE2,Ang(1-7) and Mas R staining intensity using immunohistochemistry. In addition,the natriuretic effects of tempol were observed in NS-T group,which showed an increased staining intensity of AT2,ACE2,Ang(1-7) and Mas R.CONCLUSION These findings suggest that a high salt diet leads to changes in the homeostasis and balance between opposing components of the renal RAS in hypertension to favour an increase in Ang Ⅱ. Chronic antioxidant supplementation can modulate the balance between the natriuretic and antinatriuretic components of the renal RAS. | Gabriel Cao Silvana Lorena Della Penna Nicolas Martín Kouyoumdzian Marcelo Roberto Choi Susana Gorzalczany Belisario Enrique Fernández Jorge Eduardo Toblli María Inés Roson | 2017 | World Journal of Nephrology2017，6，1： | 4 |
| 7 | Features of extrahepatic metastasis after radiofrequency ablation for hepatocellular carcinoma显示文摘BACKGROUND Extrahepatic metastasis(EHM)of hepatocellular carcinoma(HCC)is associated with poor outcomes.However,the clinical features and risk factors of EHM of HCC after radiofrequency ablation(RFA)remain unclear.AIM To elucidate the characteristics and risk factors of EHM after RFA for HCC.METHODS From January 2008 to December 2017,we retrospectively enrolled 661 patients who underwent RFA as first-line treatment for HCC at 2 tertiary hospitals.The inclusion criteria were age≥18 years,a diagnosis of HCC,and treatment-naivety.Abdominal computed tomography(CT)or magnetic resonance imaging(MRI)and alpha-fetoprotein measurements were routinely performed at 1 mo after RFA and followed-up at intervals of 3-6 mo.Univariate analyses were performed using the chi-squared test or Student’s t-test,and univariate and multivariate analyses were performed via logistic regression,as appropriate.RESULTS EHM was diagnosed in 44 patients(6.7%)during a median follow-up period of 1204 days.The 10-year cumulative rate of HCC recurrence and EHM was 92.7%and 33.7%,respectively.Initial recurrence was most often intrahepatic,and the rate of extrahepatic recurrence at initial recurrence was only 1.2%.The median time to the diagnosis of EHM was 2.68 years,and 68.2%of patients developed EHM within 2 years of the first recurrence,regardless of recurrence-free survival and 75.0%of patients developed EHM within 5 years after first recurrence.EHM was mostly diagnosed via abdominal CT/MRI in 33(75.0%)and 38 of 44 patients(86.4%)with EHM had either positive abdominal CT scan results or serum AFP level elevation.In multivariate analysis,recurrence-free survival<2 years,ablation zone/tumor size<2,and alpha-fetoprotein level>400 IU/mL were associated with a high EHM risk.CONCLUSION EHM occurs following multiple intrahepatic recurrences after RFA and combined contrast-enhanced abdominal CT and serum AFP were useful for surveillance.Patients especially with high-risk factors require close follow-up for EHM. | Jae H Yoon Young J Goo Chae-Jun Lim Sung K Choi Sung B Cho Sang S Shin Chung H Jun | 2020 | World Journal of Gastroenterology2020，26，32： | 3 |

| 9 | Prognostic value of pre-treatment F-18-FDG PET-CT in patients with hepatocellular carcinoma undergoing radioembolization显示文摘AIM To evaluate the value of pre-treatment 18F-FDG PET/CT in patients with HCC following liver radioembolization.METHODS We identified 34 patients with HCC who underwent an FDG PET/CT scan prior to hepatic radioembolization at our institution between 2009 and 2013. Patients wereseen in clinic one month after radioembolization and then at 2-3 mo intervals. We assessed the influence of FDG tumor uptake on outcomes including local liver control(LLC), distant liver control(DLC), time to distant metastases(DM), progression free survival(PFS) and overall survival(OS).RESULTS The majority of patients were males(n = 25, 74%), and had Child Pugh Class A(n = 31, 91%), with a median age of 68 years(46-84 years). FDG-avid disease was found in 19(56%) patients with SUVmax ranging from 3 to 20. Female patients were more likely to have an FDG-avid HCC(P = 0.02). Median follow up of patients following radioembolization was 12 months(1.2-62.8 mo). FDG-avid disease was associated with a decreased 1 year LLC, DLC, DM and PFS(P < 0.05). Using multivariate analysis, FDG avidity predicted for LLC, DLC, and PFS(all P < 0.05).CONCLUSION In this retrospective study, pre-treatment HCC FDGavidity was found to be associated with worse LLC, DLC, and PFS following radioembolization. Larger studies are needed to validate our initial findings to assess the role of F-18-FDG PET/CT scans as biomarker for patients with HCC following radioembolization. | Yazan Abuodeh Arash O Naghavi Kamran A Ahmed Puja S Venkat Youngchul Kim Bela Kis Junsung Choi Benjamin Biebel Jennifer Sweeney Daniel A Anaya Richard Kim Mokenge Malafa Jessica M Frakes Sarah E Hoffe Ghassan El-Haddad | 2016 | World Journal of Gastroenterology2016，22，47： | 3 |
