| 1 | 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 |
| 2 | 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 |
| 3 | 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 |

| 6 | Scalp 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 | 2011 | Neural Regeneration Research2011，6，36： | 4 |

| 12 | Effect of gastric acid suppressants and prokinetics on peritoneal dialysis-related peritonitis显示文摘AIM: To investigate the effect of gastric acid suppressants and prokinetics on peritonitis development in peritoneal dialysis(PD) patients.METHODS: This was a single-center, retrospective study. The medical records of 398 PD patients were collected from January 2000 to September 2012 and analyzed to compare patients with at least one episode of peritonitis(peritonitis group, group A) to patients who never had peritonitis(no peritonitis group, group B). All peritonitis episodes were analyzed to compare peritonitis caused by enteric organisms and peritonitis caused by non-enteric organisms.RESULTS: Among the 120 patients who met the inclusion criteria, 61 patients had at least one episode ofperitonitis and 59 patients never experienced peritonitis. Twenty-four of 61 patients(39.3%) in group A and 15 of 59 patients(25.4%) in group B used gastric acid suppressants. Only the use of H2-blocker(H2B) was associated with an increased risk of PD-related peritonitis; the use of proton pump inhibitors, other antacids, and prokinetics was not found to be a significant risk factor for PD-related peritonitis. A total of 81 episodes of peritonitis were divided into enteric peritonitis(EP) or non-enteric peritonitis, depending on the causative organism, and gastric acid suppressants and prokinetics did not increase the risk of EP in PD patients.CONCLUSION: The use of H2B showed a trend for an increased risk of overall PD-related peritonitis, although further studies are required to clarify the effects of drugs on PD-related peritonitis. | Ji Eun Kwon Seong-Joon Koh Jaeyoung Chun Ji Won Kim Byeong Gwan Kim Kook Lae Lee Jong Pil Im Joo Sung Kim Hyun Chae Jung | 2014 | World Journal of Gastroenterology2014，20，25： | 2 |

| 15 | Trends and risk factors of elderly-onset Crohn’s disease: A nationwide cohort study显示文摘BACKGROUND The incidence of inflammatory bowel disease(IBD)is increasing in Asia.Numerous risk factors associated with IBD development have been investigated.AIM To investigate trends and environmental risk factors of Crohn’s disease(CD)diagnosed in persons aged≥40 years in South Korea.METHODS Using the National Health Insurance Service database,a total of 14060821 persons aged>40 years who underwent national health screening in 2009 were followed up until December 2017.Patients with newly diagnosed CD were enrolled and compared with non-CD cohort.CD was identified according to the International Classification of Diseases 10th revision and the rare/intractable disease registration program codes from the National Health Insurance Service database.The mean follow-up periods was 7.39 years.Age,sex,diabetes,hypertension,smoking,alcohol consumption,regular exercise,body mass index,anemia,chronic kidney disease(CKD)and dyslipidemia were adjusted for in the multivariate analysis model.RESULTS During the follow-up,1337(1.33/100000)patients developed CD.Men in the middle-aged group(40-64 years)had a higher risk than women[adjusted hazard ratio(aHR)1.46,95%confidence interval(CI):1.29-1.66];however,this difference tended to disappear as the age of onset increases.In the middle-aged group,patients with a history of smoking[(aHR 1.46,95%CI:1.19-1.79)and anemia(aHR 1.85,95%CI:1.55-2.20)]had a significantly higher CD risk.In the elderly group(age,≥65 years),ex-smoking and anemia also increased the CD risk(aHR 1.68,95%CI:1.22-2.30)and 1.84(95%CI:1.47-2.30,respectively).Especially in the middle-aged group,those with CKD had a statistically elevated CD risk(aHR 1.37,95%CI:1.05-1.79).Alcohol consumption and higher body mass index showed negative association trend with CD incidence in both of the age groups.[Middle-aged:aHR 0.77(95%CI:0.66-0.89)and aHR 0.73(95% CI:0.63-0.84),respectively][Elderly-group:aHR 0.57(95% CI:0.42-0.78)and aHR 0.84(95%CI 0.67-1.04),respectively].For regular physical activity and dyslipidemia,negative correlation between CD incidences was proved only in the middle-aged group[aHR 0.88(95%CI:0.77-0.89)and aHR 0.81(95%CI:0.68-0.96),respectively].CONCLUSION History of cigarette smoking,anemia,underweight and CKD are possible risk factors for CD in Asians aged>40 years. | Jung Min Moon Eun Ae Kang Kyungdo Han Seung Wook Hong Hosim Soh Seona Park Jooyoung Lee Hyun Jung Lee Jong Pil Im Joo Sung Kim | 2020 | World Journal of Gastroenterology2020，26，4： | 2 |
| 16 | 来自一项艾日布林联合吉西他滨对比紫杉醇联合吉西他滨作为HER2阴性转移性乳腺癌的一线化疗的Ⅱ期、多中心、随机试验的包含神经病变相关量表的生活质量结果:韩国癌症研究组试验(KCSG BR13-11)显示文摘背景与目的一项比较艾日布林联合吉西他滨(eribulin plus gemcitabine,EG)或紫杉醇联合吉西他滨(paclitaxel plus gemcitabine,PG)作为转移性乳腺癌(metastatic breast cancer,MBC)患者一线化疗方案的II期临床试验发现,EG方案的神经毒性较低,但疗效与PG方案相似。在本研究中,我们分析了该临床实验中的癌症患者生命质量测评量表–紫杉烷(functional assessment of cancer therapy-taxane,FACT-Taxane)问卷评分以确定他们的生活质量(quality of life,QoL)。方法使用韩国版的FACT-Taxane问卷评估QoL。在评估基线之后,前12个疗程中每2个疗程评估1次QoL,之后每3个疗程评估1次QoL。使用线性混合模型评估EG组和PG组QoL的差异。结果在118例入组患者中,117例在基线时回复了FACT-Taxane问卷,PG组中有1例患者没有回复。EG组和PG组之间的基线QoL评分没有差异。在治疗期间,除了第11个疗程外,在第2–13个化疗疗程后,PG组紫杉烷亚量表评分显著高于EG组(均P<0.05)。神经病变特异性分析显示PG组患者的神经病症状比EG组患者更早出现且更严重(P<0.001)。结论在我们的QoL分析中,与PG方案相比,EG方案延迟并减少神经病变的发生。因此,艾日布林是MBC一线化疗药物紫杉醇的合理替代品。 | Ji‑Yeon Kim Seri Park Seock‑Ah Im Sung‑Bae Kim Joohyuk Sohn Keun Seok Lee Yee Soo Chae Ki Hyeong Lee Jee Hyun Kim Young‑Hyuck Im Tae‑Yong Kim Kyung‑Hun Lee Jin‑Hee Ahn Gun Min Kim In Hae Park Soo Jung Lee Hye Sook Han Se Hyun Kim Kyung Hae Jung Yeon Hee Park Korean Cancer Study Group | 2019 | 癌症2019，38，8： | 2 |

| 18 | Inhibition of BET selectively eliminates undifferentiated pluripotent stem cells显示文摘Embryonic stem cells(ESCs) maintain their cellular identity through the systematic regulation of master transcription factors and chromatin remodeling complexes. Recent work has shown that the unusually large-scale enhancers—namely super-enhancers(SEs), on which BRD4, a member of the bromodomain and extraterminal domain(BET) family is highly enriched—could regulate pluripotency-related transcription factors. Moreover, inhibition of BRD4 binding on SEs has been shown to induce the differentiation of ESCs. However, the underlying mechanism of BRD4 inhibition-mediated stem cell differentiation remains elusive. Here we show that both mouse and human ESCs lose their capacity for self-renewal upon treatment with JQ1, a selective inhibitor of BET family including BRD4, with rapid suppression of pluripotency-associated genes. Notably, a high concentration of JQ1 could selectively eliminate ESCs via apoptosis, without affecting the functionality of differentiated somatic cells from ESCs, suggesting that inhibition of BET may have a beneficial effect on the development of pluripotent stem cell-based cell therapy. | Jung Hyun Im Seon In Hwang Jong-Wan Kim soon-Jung Park Kyu-ree Kang Jueng Soo You Kee Pyo Kim Sung-Hwan Moon Hyuk-Jin Cha Hyung-Min Chung Hans R.
