| 1 | Prevalence of clonorchiasis in patients with gastrointestinal disease: A Korean nationwide multicenter survey显示文摘AIM: To investigate prevalence of Clonorchis sinensis in patients with gastrointestinal symptoms, and the relation of the infection to hepatobiliary diseases in 26 hospitals in Korea.METHODS: Consecutive patients who had been admitted to the Division of Gastroenterology with gastrointestinal symptoms were enrolled from March to April 2005. Of those who had been diagnosed with clonorchiasis, epidemiology and correlation between infection and hepatobiliary diseases were surveyed by questionnaire.RESULTS: Of 3080 patients with gastrointestinal diseases, 396 (12.9%) had clonorchiasis and 1140 patients (37.2%) had a history of eating raw freshwater fish. Of those with a history of raw freshwater fish ingestion, 238 (20.9%) patients had clonorchiasis. Cholangiocarcinoma was more prevalent in C. sinensis-infected patients than non-infected patients [34/396 (8.6%) vs 145/2684 (5.4%), P = 0.015]. Cholangiocarcinoma and clonorchiasis showed statistically significant positive cross-relation (P = 0.008). Choledocholithiasis, cholecystolithiasis, cholangitis, hepatocellular carcinoma, and biliary pancreatitis did not correlate with clonorchiasis.CONCLUSION: Infection rate of clonorchiasis was still high in patients with gastrointestinal diseases in Korea, and has not decreased very much during the last two decades. Cholangiocarcinoma was related to clonorchiasis, which suggested an etiological role for the parasite. | Ho Gak Kim Jimin Han Myung-Hwan Kim Kyu Hyun Cho Im Hee Shin Gwang Ha Kim Jae Seon Kim Jin Bong Kim Tae Nyeun Kim Tae Hyeon Kim Tae Hyo Kim Jae Woo Kim Ji Kon Ryu Young-Soo Moon Jong Ho Moon Sung Jae Park Chan Guk Park Sung-Jo Bang Chang Heon Yang Kyo-Sang Yoo Byung Moo Yoo Kyu Taek Lee Dong Ki Lee Byung Seok Lee Sang Soo Lee Seung Ok Lee Woo Jin Lee Chang Min Cho Young-Eun Joo Gab Jin Cheon Young Woo Choi Jae Bok Chung Yong Bum Yoon | 2009 | World Journal of Gastroenterology2009,15,1: | 15 |

| 3 | Long-term outcome in patients with obscure gastrointestinal bleeding after negative capsule endoscopy显示文摘AIM:To investigate long-term outcome in obscure gastrointestinal bleeding(OGIB) after negative capsule endoscopy(CE) and identify risk factors for rebleeding.METHODS:A total of 113 consecutive patients underwent CE for OGIB from May 2003 to June 2010 at Seoul National University Hospital.Ninety-five patients(84.1%) with a subsequent follow-up after CE of at least 6 mo were enrolled in this study.Follow-up data were obtained from the patients' medical records.The CE images were reviewed by two board-certified gastroenterologists and consensus diagnosis was used in all cases.The primary outcome measure was the detection of rebleeding after CE,and factors associated with rebleeding were evaluated using multivariate analysis.RESULTS:Of the 95 enrolled patients(median age 61 years,range 17-85 years),62 patients(65.3%) were male.The median duration of follow-up was 23.7 mo(range 6.0-89.4 mo).Seventy-three patients(76.8%) underwent CE for obscure-overt bleeding.Complete examination of the small bowel was achieved in 77 cases(81.1%).Significant lesions were found in 38 patients(40.0%).The overall rebleeding rate was 28.4%.The rebleeding rate was higher in patients with positive CE(36.8%) than in those with negative CE(22.8%).However,there was no significant difference in cumulative rebleeding rates between the two groups(log rank test;P = 0.205).Anticoagulation after CE examination was an independent risk factor for rebleeding(hazard ratio,5.019;95%CI,1.560-16.145;P = 0.007),regardless of CE results.CONCLUSION:Patients with OGIB and negative CE have a potential risk of rebleeding.Therefore,close observation is required and alternative modalities should be considered in suspicious cases. | Seong-Joon Koh Jong Pil Im Ji Won Kim Byeong Gwan Kim Kook Lae Lee Sang Gyun Kim Joo Sung Kim Hyun Chae Jung | 2013 | World Journal of Gastroenterology2013,19,10: | 12 |
| 4 | Predicting the Rainfall-Triggered Landslides in a Forested Mountain Region Using TRIGRS Model显示文摘Landslides are natural disasters which can pose a serious threat to human and property in many areas around the world. The Transient Rainfall Infiltration and Grid-based Regional Slope-stability (TRIGRS) model was used to investigate the rainfall-induced shallow landslides in a forested mountain region, Korea. Various input data for TRIGRS model include time-varying rainfall, topographic characteristics, soil depth, material strength, and hydraulic properties. A series of calculations were conducted in determining the slope stability over the Jangheung region in Korea during the storm occurred on August 6, 1998. The results show that TRIGRS model captured about 64.1% of landslides that were extracted from the IKONOS2 imageries. The model demonstrated how the factor of safety changed with time during a storm considering both the transient and spatial responses of pore water pressure in its slope stability calculation. | Dongyeob KIM Sangjun IM Sang Ho LEE Youngjoo HONG Kyung-Sub CHA | 2010 | Journal of Mountain Science2010,7,1: | 10 |
| 5 | Clinicopathologic factors influencing the accuracy of EUS for superficial esophageal carcinoma显示文摘AIM:To identify clinicopathologic factors influencing the accuracy of a high-frequency catheter probe endoscopic ultrasonography(EUS)for superficial esophageal carcinomas(SECs).METHODS:A total of 126 patients with endoscopically suspected SEC,who underwent EUS and curative treatment at Pusan National University Hospital during2005-2013,were enrolled.We reviewed the medical records of the 126 patients and compared EUS findings with histopathologic results according to clinicopathologic factors.RESULTS:A total of 114 lesions in 113 patients were included in the final analysis.The EUS assessment of tumor invasion depth was accurate in 78.9%(90/114)patients.Accuracy did not differ according to histologic type,tumor differentiation,tumor location,or macroscopic shape.However,accuracy significantly decreased for tumors≥3 cm in size(P=0.002).Overestimation and underestimation of the invasion depth occurred for 11(9.6%)and 13 lesions(11.4%),respectively.In multivariate analyses,tumor size≥3 cm was the only factor significantly associated with EUS accuracy(P=0.031),and was specifically associated with the underestimation of invasion depth.CONCLUSION:EUS using a high-frequency catheter probe generally provides highly accurate assessments of SEC invasion depth,but its accuracy decreases for tumors≥3 cm. | Jung Im Jung Gwang Ha Kim Hoseok I Do Youn Park Tae Kyun Kim Young Hwa Cho Yong Wan Sung Mun Ki Choi Bong Eun Lee Geun Am Song | 2014 | World Journal of Gastroenterology2014,20,20: | 9 |
| 6 | In-situ formation of MOF derived mesoporous Co3N/amorphous N-doped carbon nanocubes as an efficient electrocatalytic oxygen evolution reaction显示文摘The suitable materials,metal nitrides,are a promising class of electrocatalyst materials for a highly efficient oxygen evolution reaction (OER) because they exhibit superior intrinsic conductivity and have higher sustainability than oxide-based materials.To our knowledge,for the first time,we report a designable synthesis of three-dimensional (3D) and mesoporous Co3N@ amorphous N-doped carbon (AN-C) nanocubes (NCs) with well-controlled open-framework structures via monodispersed Co3[Co(CN)6]2 Prussian blue analogue (PBA) NC precursors using in situ nitridation and calcination processes.Co3N@AN-C NCs (2 h) demonstrate better OER activity with a remarkably low Tafel plot (69.6 mV-dec-1),low overpotential of 280 mV at a current density of 10 mA-crrf2.Additionally,excellent cycling stability in alkaline electrolytes was exhibited without morphological changes and voltage elevations,superior to most reported hierarchical structures of transition-metal nitride particles.The presented strategy for synergy effects of metal-organic frameworks (MOFs)-derived transition-metal nitrides-carbon hybrid nanostructures provides prospects for developing high-performance and advanced electrocatalyst materials. | Bong Kyun Kang Seo Young Im Jooyoung Lee Sung Hoon Kwag Seok Bin Kwon SintayehuNibret Tiruneh Min-Jun Kim Jung Ho Kim Woo Seok Yang Byungkwon Lim Dae Ho Yoon | 2019 | Nano Research2019,12,7: | 8 |
| 7 | Increased end-stage renal disease risk in patients with inflammatory bowel disease:A nationwide populationbased study显示文摘AIM To estimate the risk of end-stage renal disease(ESRD)in patients with inflammatory bowel disease(IBD).METHODS From January 2010 to December 2013, patients with Crohn's disease(CD) and ulcerative colitis(UC) were identified, based on both the International Classification of Diseases, 10 th revision(ICD-10) and the rare,intractable disease registration program codes from the National Health Insurance(NHI) database in South Korea. We compared 38812 patients with IBD to ageand sex-matched non-IBD controls with a ratio of 1:3.Patients newly diagnosed with ESRD were identified with the ICD-10 code.RESULTS During a mean follow-up of 4.9 years, ESRD was detected in 79(0.2%) patients with IBD and 166(0.1%)controls. The incidence of ESRD in patients with IBD was0.42 per 1000 person-years. Patients with IBD had a significantly higher risk of ESRD than controls [adjusted hazard ratio(HR) = 3.03; 95% confidence interval(CI):1.77-5.20; P < 0.001]. The incidences(per 1000 personyears)of ESRD were 0.51 in patients with CD and 0.13 in controls, respectively(adjusted HR = 6.33; 95%CI:2.75-14.56; P < 0.001). In contrast, the incidence of ESRD was similar between the UC and control groups(0.37 vs 0.37 per 1000 person-years; adjusted HR = 2.01;95%CI: 0.90-4.51; P = 0.089).CONCLUSION The risk of ESRD was elevated in patients with CD, but not UC. Patients with CD should be monitored carefully for signs of renal insufficiency. | Seona Park Jaeyoung Chun Kyung-Do Han Hosim Soh Kookhwan Choi Ji Hye Kim Jooyoung Lee Changhyun Lee Jong Pil Im Joo Sung Kim | 2018 | World Journal of Gastroenterology2018,24,42: | 7 |
| 8 | Clinical and endoscopic characteristics of drug-induced esophagitis显示文摘AIM: To investigate clinical, endoscopic and pathological characteristics of drug-induced esophagitis.METHODS: Data for patients diagnosed with drug-induced esophagitis from April 2002 to May 2013 was reviewed. Patients diagnosed with malignancy, viral or fungal esophagitis were excluded. Clinical, endoscopic and pathological characteristics of patients diagnosed with drug-induced esophagitis were analyzed.RESULTS: Seventy-eight patients were diagnosed with drug-induced esophagitis. Their mean age was 43.9 ± 18.9 years and 35.9% were male. Common symptoms were chest pain(71.8%), odynophagia(38.5%) and dysphagia(29.5%). The endoscopic location was in the middle third of esophagus in 78.2%. Endoscopic findings were ulcer(82.1%), erosion(17.9%), ulcer with bleeding(24.4%), coating with drug material(5.1%), impacted pill fragments(3.8%) and stricture(2.6%). Kissing ulcers were observed in 43.6%. The main causative agents were antibiotics and non-steroidal antiinflammatory drugs. All the patients were treated with proton pump inhibitors(PPIs) or sucralfate, and the causative drugs were discontinued. Nineteen patients with drug-induced esophagitis were followed up with endoscopy and revealed normal findings, scars or healing ulcers.CONCLUSION: Drug-induced esophagitis mainly presents as chest pain, odynophagia and dysphagia, and may be successfully treated with PPIs and discontinuation of the causative drug. Kissing ulcers were observed in 43.6%. | Su Hwan Kim Ji Bong Jeong Ji Won Kim Seong-Joon Koh Byeong Gwan Kim Kook Lae Lee Mee Soo Chang Jong Pil Im Hyoun Woo Kang Cheol Min Shin | 2014 | World Journal of Gastroenterology2014,20,31: | 7 |
| 9 | Risk of inflammatory bowel disease in patients with chronic obstructive pulmonary disease: A nationwide, population-based study显示文摘BACKGROUND There is a growing evidence regarding an increased risk of inflammatory bowel disease(IBD)among patients with airway diseases.AIM To investigate the influence of chronic obstructive pulmonary disease(COPD)on the risk of IBD.METHODS A nationwide,population-based study was conducted using data from the National Health Insurance Service database.A total of 1303021 patients with COPD and 6515105 non-COPD controls were identified.The COPD group was divided into the severe and the mild COPD group according to diagnostic criteria.The risk of IBD in patients with COPD compared to controls was analyzed by Cox proportional hazard regression models.The cumulative incidences of IBD were compared between the groups.RESULTS The COPD group had higher incidences of IBD compared to non-COPD controls(incidence rate,9.98 vs 7.18 per 100000 person-years,P<0.001).The risk of IBD in the COPD group was increased by 1.38(adjusted hazard ratio(HR);95%CI:1.25-1.52).The incidence rate of IBD was higher in the severe COPD group than in the mild COPD group(12.39 vs 9.77 per 100000 person-year,P<0.001).The severity of COPD was associated with an increased risk of IBD(adjusted HR 1.70 in severe COPD,95%CI:1.27-2.21 and adjusted HR 1.35 in mild COPD,95%CI:1.22-1.49)CONCLUSION The incidences of IBD were significantly increased in COPD patients in South Korea and the risk of developing IBD also increased as the severity of COPD increased. | Jooyoung Lee Jong Pil Im Kyungdo Han Seona Park Hosim Soh Kukhwan Choi Jihye Kim Jaeyoung Chun Joo Sung Kim | 2019 | World Journal of Gastroenterology2019,25,42: | 7 |
| 10 | Identifying Pb-free perovskites for solar cells by machine learning显示文摘Recent advances in computing power have enabled the generation of large datasets for materials,enabling data-driven approaches to problem-solving in materials science,including materials discovery.Machine learning is a primary tool for manipulating such large datasets,predicting unknown material properties and uncovering relationships between structure and property.Among state-of-the-art machine learning algorithms,gradient-boosted regression trees(GBRT)are known to provide highly accurate predictions,as well as interpretable analysis based on the importance of features.Here,in a search for lead-free perovskites for use in solar cells,we applied the GBRT algorithm to a dataset of electronic structures for candidate halide double perovskites to predict heat of formation and bandgap.Statistical analysis of the selected features identifies design guidelines for the discovery of new lead-free perovskites. | Jino Im Seongwon Lee Tae-Wook Ko Hyun Woo Kim YunKyong Hyon Hyunju Chang | 2019 | npj Computational Materials2019,,1: | 6 |
| 11 | Negative impact of bone-marrow-derived mesenchymal stem cells on dextran sulfate sodium-induced colitis显示文摘AIM:To investigate the effects of mesenchymal stem cells(MSCs)on dextran sulfate sodium-induced inflammatory bowel disease(IBD).METHODS:C57BL/6 mice were fed 3.5%(g/L)dextran sulfate sodium.On day seven,the mice received intraperitoneal injections of 1×106 MSCs.The survival rate,disease activity index values,and body weight,were monitored daily.On day ten,colon lengths and histopathologic changes were assessed.In addition,immunoregulatory changes following MSC administration were evaluated by determining the levels of effector T cell responses in the spleen and mesenteric lymph nodes,and the expression levels of inflammatory cytokines in homogenized colons.RESULTS:Intraperitoneal administration of MSCs did not prevent development of colitis and did not reduce the clinicopathologic severity of IBD.No significant difference was evident in either survival rate or disease activity index score between the control and MSCtreated group.Day ten-sacrificed mice exhibited no significant difference in either colon length or histopathologic findings.Indeed,the MSC-treated group exhibited elevated levels of interleukin(IL)-6 and transforming growth factor-β,and a reduced level of IL-10,in spleens,mesenteric lymph nodes,and homogenized colons.The IL-17 level was lower in the mesenteric lymph nodes of the MSC-treated group(P=0.0126).In homogenized colons,the IL-17 and tumor necrosis factor-α(P=0.0092)expression levels were also lower in the treated group.CONCLUSION:MSC infusion provided no significanthistopathologic or clinical improvement,thus representing a limited therapeutic approach for IBD.Functional enhancement of MSCs is needed in further study. | Young-Sun Nam Nayoun Kim Keon-Il Im Jung-Yeon Lim Eun-Sol Lee Seok-Goo Cho | 2015 | World Journal of Gastroenterology2015,21,7: | 6 |
| 12 | Cinnamon extract suppresses experimental colitis through modulation of antigen-presenting cells显示文摘AIM:To investigate the anti-inflammatory effects of cinnamon extract and elucidate its mechanisms for targeting the function of antigen presenting cells.METHODS:Cinnamon extract was used to treat murine macrophage cell line(Raw 264.7),mouse primary antigen-presenting cells(APCs,MHCII+) and CD11c+dendritic cells to analyze the effects of cinnamon extract on APC function.The mechanisms of action of cinnamon extract on APCs were investigated by analyzing cytokine production,and expression of MHC antigens and co-stimulatory molecules by quantitative real-time PCR and flow cytometry.In addition,the effect of cinnamon extract on antigen presentation capacity and APC-dependent T-cell differentiation were analyzed by [H3]-thymidine incorporation and cytokine analysis,respectively.To confirm the anti-inflammatory effects of cinnamon extract in vivo,cinnamon or PBS was orally administered to mice for 20 d followed by induction of experimental colitis with 2,4,6 trinitrobenzenesulfonic acid.The protective effects of cinnamon extract against experimental colitis were measured by checking clinical symptoms,histological analysis and cytokine expression prof iles in inflamed tissue.RESULTS:Treatment with cinnamon extract inhibited maturation of MHCII+ APCs or CD11c+ dendritic cells(DCs) by suppressing expression of co-stimulatory molecules(B7.1,B7.2,ICOS-L),MHCII and cyclooxygenase(COX)-2.Cinnamon extract induced regulatory DCs(rDCs) that produce low levels of pro-inflammatory cytokines [interleukin(IL)-1β,IL-6,IL-12,interferon(IFN)-γ and tumor necrosis factor(TNF)-α] while expressing high levels of immunoregulatory cytokines(IL-10 and transforming growth factor-β).In addition,rDCs generated by cinnamon extract inhibited APC-dependent T-cell proliferation,and converted CD4+ T cells into IL-10high CD4+ T cells.Furthermore,oral administration of cinnamon extract inhibited development and progression of intestinal colitis by inhibiting expression of COX-2 and pro-inflammatory cytokines(IL-1β,IFN-γ and TNF-α),while enhancing IL-10 levels.CONCLUSION:Our study suggests the potential of cinnamon extract as an anti-inflammatory agent by targeting the generation of regulatory APCs and IL-10+ regulatory T cells. | Ho-Keun Kwon Ji-Sun Hwang Choong-Gu Lee Jae-Seon So Anupama Sahoo Chang-Rok Im Won Kyung Jeon Byoung Seob Ko Sung Haeng Lee Zee Yong Park Sin-Hyeog Im | 2011 | World Journal of Gastroenterology2011,17,8: | 6 |

| 16 | Hybridisation of perovskite nanocrystals with organic molecules for highly efficient liquid scintillators显示文摘Compared with solid scintillators,liquid scintillators have limited capability in dosimetry and radiography due to their relatively low light yields.Here,we report a new generation of highly efficient and low-cost liquid scintillators constructed by surface hybridisation of colloidal metal halide perovskite CsPbA_(3)(A:Cl,Br,I)nanocrystals(NCs)with organic molecules(2,5-diphenyloxazole).The hybrid liquid scintillators,compared to state-of-the-art CsI and Gd_(2)O_(2)S,demonstrate markedly highly competitive radioluminescence quantum yields under X-ray irradiation typically employed in diagnosis and treatment.Experimental and theoretical analyses suggest that the enhanced quantum yield is associated with X-ray photon-induced charge transfer from the organic molecules to the NCs.High-resolution X-ray imaging is demonstrated using a hybrid CsPbBr_(3) NC-based liquid scintillator.The novel X-ray scintillation mechanism in our hybrid scintillators could be extended to enhance the quantum yield of various types of scintillators,enabling low-dose radiation detection in various fields,including fundamental science and imaging. | Sangeun Cho Sungwoo Kim Jongmin Kim Yongcheol Jo Ilhwan Ryu Seongsu Hong Jae-Joon Lee SeungNam Cha Eun BiNam Sang Uck Lee Sam Kyu Noh Hyungsang Kim Jungwon Kwak Hyunsik Im | 2020 | Light(Science & Applications)2020,9,1: | 4 |
| 17 | Periodontitis combined with smoking increases risk of the ulcerative colitis: A national cohort study显示文摘BACKGROUND Periodontitis is a chronic inflammation of periodontal tissues.The effect of periodontitis on the development of inflammatory bowel disease(IBD)remains unclear.AIM To assessed the risk of IBD among patients with periodontitis,and the risk factors for IBD related to periodontitis.METHODS A nationwide population-based cohort study was performed using claims data from the Korean National Healthcare Insurance Service.In total,9950548 individuals aged≥20 years who underwent national health screening in 2009 were included.Newly diagnosed IBD[Crohn’s disease(CD),ulcerative colitis(UC)]using the International Classification of Disease 10th revision and rare intractable disease codes,was compared between the periodontitis and nonperiodontitis groups until 2017.RESULTS A total of 1092825 individuals(11.0%)had periodontitis.Periodontitis was significantly associated with older age,male gender,higher body mass index,quitting smoking,not drinking alcohol,and regular exercise.The mean age was 51.4±12.9 years in the periodontitis group and 46.6±14.2 years in the nonperiodontitis group(P<0.01),respectively.The mean body mass index was 23.9±3.1 and 23.7±3.2 in the periodontitis and non-periodontitis groups,respectively(P<0.01).Men were 604307(55.3%)and 4844383(54.7%)in the periodontitis and non-periodontitis groups,respectively.The mean follow-up duration was 7.26 years.Individuals with periodontitis had a significantly higher risk of UC than those without periodontitis[adjusted hazard ratio:1.091;95%confidence interval(CI):1.008-1.182],but not CD(adjusted hazard ratio:0.879;95%confidence interval:0.731-1.057).The risks for UC were significant in the subgroups of age≥65 years,male gender,alcohol drinker,current smoker,and reduced physical activity.Current smokers aged≥65 years with periodontitis were at a 1.9-fold increased risk of UC than non-smokers aged≥65 years without periodontitis.CONCLUSION Periodontitis was significantly associated with the risk of developing UC,but not CD,particularly in current smokers aged≥65 years. | Eun Ae Kang Jaeyoung Chun Jee Hyun Kim Kyungdo Han Hosim Soh Seona Park Seung Wook Hong Jung Min Moon Jooyoung Lee Hyun Jung Lee Jun-Beom Park Jong Pil Im Joo Sung Kim | 2020 | World Journal of Gastroenterology2020,26,37: | 3 |
