1Prevalence 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 2009World Journal of Gastroenterology2009,15,1:15

3Clinical analysis of risk factors contributing to recurrence of pterygium after excision and graft surgery显示文摘AIM: To find the risk factors related to the reproliferation of the pterygial tissue after excision and graft surgery.METHODS: Charts of 130 eyes of 130 patients who had pterygial excision from March 2006 to April 2011 were reviewed. Preoperative pterygium morphology, surgical methods, and adjunctive treatments were statistically analyzed for their relationship with recurrence.RESULTS: During the follow-up period, recurrence was observed in 20 eyes(15.4%). None of the preoperative morphologic features were affected the rate of the recurrence. However, an age <40y [P =0.085, odds ratio(OR) 3.609, 95% confidence interval(CI) 0.838-15.540]and amniotic membrane graft instead of conjunctival autograft(P =0.002, OR 9.093, 95% CI 2.316-35.698) were statistically significant risk factors for recurrence.Multivariate analysis revealed that intraoperative mitomycin C(MMC)(P =0.072, OR 0.298, 95% CI 0.080-1.115)decreased the rate of recurrence. CONCLUSION: Younger age is a risk factor for reproliferation of pterygial tissue after excision and amniotic membrane transplantation(AMT) are less effective in preventing recurrence of pterygium after excision based on the comparison between conjunctival autograft and AMT. Intraoperative MMC application and conjunctival autograft reduce recurrence.Sang Won Ha Joon Ho Park Im Hee Shin Hong Kyun Kim 2015International Journal of Ophthalmology(English edition)2015,8,3:13
4Efficacy of Saam acupuncture treatment on improvement of immune cell numbers in cancer patients:a pilot study显示文摘OBJECTIVE: To collect preliminary data on the effects of Saam acupuncture with regard to the immunity in cancer patients.METHODS: Ten cancer patients were analyzed for improvements in immunity. Acupuncture was applied at the 5 acupuncture points, Jingqu(LU 8), Zutonggu(BL 66), Yanggu(SI 5), Yangchi(TE 4), and Zhongwan(CV 12) for 2 weeks with 4 sessions. We assessed the effect of Korean Saam acupuncture on the immune system in cancer patients by measuring particular blood cell subsets, including CD3 +,CD4+, CD8+, CD19+, and CD56+ cells, as well as total white blood cell count, absolute neutrophil count, and fatigue score. The measurement was performed before and after acupuncture and at a 2-week follow-up.RESULTS: There was a statistically significant increase in the number of CD3+(P=0.023) and CD8+ cells(P<0.001) and T-cell subsets, as well as a decrease in the fatigue severity scale(FSS) score(P=0.001) after Saam acupuncture using the 5 acupoints.CONCLUSION: Acupuncture may improve the immune system by increasing the counts of a few immune cells and relieve fatigue in cancer patients by decreasing FSS scores. Although this was a non-controlled study, it constitutes preliminary research investigating the potential effects of Saam acupuncture in increasing the counts of several immune cells in cancer patients.Dae-Joon Kim Seong-Hoon Park Jung-Chul Seo Kyung Soon Kim Ki Cheul Sohn Im Hee Shin Hun Mo Ryoo 2014Journal of Traditional Chinese Medicine2014,34,5:11
5Clinicopathologic 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 2014World Journal of Gastroenterology2014,20,20:9
6Increased 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 2018World Journal of Gastroenterology2018,24,42:7
7Risk 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 2019World Journal of Gastroenterology2019,25,42:7
8An inside-out vein graft filled with platelet-rich plasma for repair of a short sciatic nerve defect in rats显示文摘Platelet-rich plasma containing various growth factors can promote nerve regeneration. An inside-out vein graft can substitute nerve autograft to repair short nerve defects. It is hypothesized that an inside-out vein graft filled with platelet-rich plasma shows better effects in the repair of short sciatic nerve defects. In this study, an inside-out vein autograft filled with platelet-rich plasma was used to bridge a 10 mm-long sciatic nerve defect in rats. The sciatic nerve function of rats with an inside-out vein autograft filled with platelet-rich plasma was better improved than that of rats with a simple inside-out vein autograft. At 6 and 8 weeks, the sciatic nerve function of rats with an inside-out vein autograft filled with platelet-rich plasma was better than that of rats undergoing nerve autografting. Compared with the sciatic nerve repaired with a simple inside-out vein autograft, the number of myelinated axons was higher, axon diameter and myelin sheath were greater in the sciatic nerve repaired with an inside-out vein autograft filled with platelet-rich plasma and they were similar to those in the sciatic nerve repaired with nerve autograft. These findings suggest that an inside-out vein graft filled with platelet-rich plasma can substitute nerve autograft to repair short sciatic nerve defects.Ji Yeong Kim Woo Joo Jeon Dong Hwee Kim Im Joo Rhyu Young Hwan Kim Inchan Youn Jong Woong Park 2014Neural Regeneration Research2014,9,14:6
9Heterostructures in two-dimensional colloidal metal chalcogenides:Synthetic fundamentals and applications显示文摘As a new class of two-dimensional materials, two-dimensional (2D) heterostructures constructed from metal chalcogenides (MCs) have been gaining tremendous attention due to their unprecedented physical and chemical phenomena, mainly originated from their distinct structural features such as composition, architecture type, spatial arrangement of each component, crystal structure, exposed facet and interface, dimensionality in their heterostructures. Towards the realization of practical applications, synthetic approaches need a rational design with a variety of architecture types including laterally-combined, vertically-aligned, and conformally-coated 2D MC heterostructures. Among various synthetic routes, solution-based synthesis is thought of as an alternative to fabrication through high-cost setups since it can control those structural features in a cheap fashion. This review presents recent progress on solution-based synthesis to produce various 2D MC heterostructures with a focus on the synthetic fundamentals in terms of thermodynamic and kinetic aspects related to the growth mechanism. Four different synthetic approaches are reviewed: seeded growth, cation exchange reaction, colloidal atomic layer deposition, direct synthesis including one-step process and modified electrochemical method. We also provide some representative applications of 2D MC heterostructures and their hybrid composites in various fields including optoelectronics, thermoelectrics, catalysis, and battery. Finally, we offer an insight into challenges and future directions in a synthetic improvement of 2D MC heterostructures.Yuho Min Eunmi Im Geon-Tae Hwang Jong-Woo Kim Cheol-Woo Ahn Jong-Jin Choi Byung-Dong Hahn Joon-Hwan Choi Woon-Ha Yoon Dong-Soo Park Dong Choon Hyun Geon Dae Moon 2019Nano Research2019,12,8:6
10Stochastic structural optimization using particle swarm optimization, surrogate models and Bayesian statistics显示文摘This paper focuses on a method to solve structural optimization problems using particle swarm optimization (PSO), surrogate models and Bayesian statistics. PSO is a random/stochastic search algorithm designed to find the global optimum. However, PSO needs many evaluations compared to gradient-based optimization. This means PSO increases the analysis costs of structural optimization. One of the methods to reduce computing costs in stochastic optimization is to use approximation techniques. In this work, surrogate models are used, including the response surface method (RSM) and Kriging. When surrogate models are used, there are some errors between exact values and approximated values. These errors decrease the reliability of the optimum values and discard the realistic approximation of using surrogate models. In this paper, Bayesian statistics is used to obtain more reliable results. To verify and confirm the efficiency of the proposed method using surrogate models and Bayesian statistics for stochastic structural optimization, two numerical examples are optimized, and the optimization of a hub sleeve is demonstrated as a practical problem.Jongbin Im Jungsun Park 2013Chinese Journal of Aeronautics2013,26,1:6
11Cinnamon 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 2011World Journal of Gastroenterology2011,17,8:6
12Scalp electroacupuncture at the Baihui acupoint (DU 20) improves functional recovery in rats with cerebral ischemia Association with increased expression of vascular endothelial growth factors显示文摘In this study, we induced cerebral infarction in rats by occluding the right middle cerebral artery, and tested the effects of electroacupuncture at the Baihui acupoint (DU 20). Motor and sensory function was tested using Garcia’s scale and motor weakness grading, and the expression of vascular endothelial growth factor in the brain was quantified using immunoblotting and immunohistochemistry. We found that scalp electroacupuncture at DU 20 significantly improved motor performance and sensory function in rats with stroke, and this was accompanied by an increased expression of vascular endothelial growth factor in the ischemic brain tissue and peri-ischemic area. In addition, Pearson correlation analysis showed that the improvements in functional recovery were correlated with the increased expression of vascular endothelial growth factor.Min-Wook Kim You Chul Chung Hee Chan Jung Moon-Seo Park Young-Min Han Yong-An Chung Lee-So Maeng Sang-In Park Jiyeon Lim Seung Chan Kim Woo-Seok Im Jin Young Chung Minky Kim Manho Kim 2011Neural Regeneration Research2011,6,36:4
13Al-incorporation into Li7La3Zr2O12 solid electrolyte keeping stabilized cubic phase for all-solid-state Li batteries显示文摘We observe the influence of Al occupancies in Li sites on the formation process of the garnet solid electrolyte of Li_7La_3Zr_2O_(12)(LLZO).A direct incorporation of Al is first promoted in a Li-insufficient garnet solid electrolyte during the calcination process of 850°C and then the cubic phase of LLZO is obtained after successive annealing step of 1000°C.Comparing to pristine LLZO,Al incorporated LLZO shows less formation of Li_2CO_3,keeping crystallographic and physicochemical properties.This Al incorporation improves both the ionic conductivity and interfacial resistance to poisoning procedure.Changbin Im Dongwon Park Hosung Kim Jaeyoung Lee 2018Journal of Energy Chemistry2018,27,5:4
14Human mesenchymal stem cells derived from umbilical cord and bone marrow exert immunomodulatory effects in different mechanisms显示文摘BACKGROUND Mesenchymal stem cells(MSCs)are an attractive tool to treat graft-versus-host disease because of their unique immunoregulatory properties.Although human bone marrow-derived MSCs(BM-MSCs)were the most widely used MSCs in cell therapy until recently,MSCs derived from human umbilical cords(UC-MSCs)have gained popularity as cell therapy material for their ethical and noninvasive collection.AIM To investigate the difference in mechanisms of the immunosuppressive effects of UC-MSCs and BM-MSCs.METHODS To analyze soluble factors expressed by MSCs,such as indolamine 2,3-dioxygenase,cyclooxygenase-2,prostaglandin E2 and interleukin(IL)-6,inflammatory environments in vitro were reconstituted with combinations of interferon-gamma(IFN-γ),tumor necrosis factor alpha and IL-1βor with IFN-γalone.Activated T cells were cocultured with MSCs treated with indomethacin and/or anti-IL-10.To assess the ability of MSCs to inhibit T helper 17 cells and induce regulatory T cells,induced T helper 17 cells were cocultured with MSCs treated with indomethacin or anti-IL-10.Xenogeneic graft-versus-host disease was induced in NOG mice(NOD/Shi-scid/IL-2Rγnull)and UC-MSCs or BM-MSCs were treated as cell therapies.RESULTS Our data demonstrated that BM-MSCs and UC-MSCs shared similar phenotypic characteristics and immunomodulation abilities.BM-MSCs expressed more indolamine 2,3-dioxygenase after cytokine stimulation with different combinations of IFN-γ,tumor necrosis factor alpha-αand IL-1βor IFN-γalone.UC-MSCs expressed more prostaglandin E2,IL-6,programmed death-ligand 1 and 2 in the in vitro inflammatory environment.Cyclooxygenase-2 and IL-10 were key factors in the immunomodulatory mechanisms of both MSCs.In addition,UC-MSCs inhibited more T helper 17 cells and induced more regulatory T cells than BM-MSCs.UC-MSCs and BM-MSCs exhibited similar effects on attenuating graft-versus-host disease.CONCLUSION UC-MSCs and BM-MSCs exert similar immunosuppressive effects with different mechanisms involved.These findings suggest that UC-MSCs have distinct immunoregulatory functions and may substitute BM-MBSCs in the field of cell therapy.Yunejin Song Jung-Yeon Lim Taekyu Lim Keon-Il Im Nayoun Kim Young-Sun Nam Young-Woo Jeon Jong Chul Shin Hyun Sun Ko In Yang Park Seok-Goo Cho 2020World Journal of Stem Cells2020,12,9:4
15Periodontitis 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 2020World Journal of Gastroenterology2020,26,37:3
