| 1 | Somatostatin adjunctive therapy for non-variceal upper gastrointestinal rebleeding after endoscopic therapy显示文摘AIM:To evaluate the effect of pantoprazole with a somatostatin adjunct in patients with acute non-variceal upper gastrointestinal bleeding(NVUGIB).METHODS:We performed a retrospective analysis of a prospective database in a tertiary care university hospital.From October 2006 to October 2008,we enrolled 101 patients with NVUGIB that had a high-risk stigma on endoscopy.Within 24 h of hospital admission,all patients underwent endoscopic therapy.After successful endoscopic hemostasis,all patients received an 80-mg bolus of pantoprazole followed by continuous intravenous infusion(8 mg/h for 72 h).The somatostatin adjunct group(n=49)also received a 250-μg bolus of somatostatin,followed by continuous infusion (250μg/h for 72 h).Early rebleeding rates,disappearance of endoscopic stigma and risk factors associated with early rebleeding were examined.RESULTS:Early rebleeding rates were not significantly different between treatment groups(12.2%vs 14.3%,P=0.766).Disappearance of endoscopic stigma on the second endoscopy was not significantly different between treatment groups(94.2%vs 95.9%,P=0.696).Multivariate analysis showed that the complete Rockall score was a significant risk factor for early rebleeding(P =0.044,OR:9.080,95%CI:1.062-77.595).CONCLUSION:The adjunctive use of somatostatin was not superior to pantoprazole monotherapy after successful endoscopic hemostasis in patients with NVUGIB. | Cheol Woong Choi Dae Hwan Kang Hyung Wook Kim Su Bum Park Kee Tae Park Gwang Ha Kim Geun Am Song Mong Cho | 2011 | World Journal of Gastroenterology2011,17,29: | 15 |
| 2 | Is it possible to differentiate gastric GISTs from gastric leiomyomas by EUS?显示文摘AIM: To evaluate the ultrasonog raphy (EUS) features of gastric gastrointestinal stromal tumors (GISTs) as compared with gastric leiomyomas and then to determine the EUS features that could predict malignant GISTs.METHODS: We evaluated the endoscopic EUS features in 53 patients with gastric mesenchymal tumors conf irmed by histopathologic diagnosis. The GISTs were classif ied into benign and malignant groups according to the histological risk classif ication.RESULTS: Immunohistochemical analyses demon-strated 7 leiomyomas and 46 GISTs. Inhomogenicity, hyperechogenic spots, a marginal halo and higher echogenicity as compared with the surrounding muscle layer appeared more frequently in the GISTs than in the leiomyomas (P < 0.05). The presence of at least two of these four features had a sensitivity of 89.1% and a specifi city of 85.7% for predicting GISTs. Except for tumor size and irregularity of the border, most of the EUS features were not helpful for predicting the malignant potential of GISTs. On multivariate analysis, only the maximal diameter of the GISTs was an independent predictor. The optimal size for predicting malignant GISTs was 35 mm. The sensitivity and specificity using this value were 92.3% and 78.8%, respectively.CONCLUSION: EUS may help to differentiate gastric GISTs from gastric leiomyomas. Once GISTs are suspected, surgery should be considered if the size is greater than 3.5 cm. | Gwang Ha Kim Do Youn Park Suk Kim Dae Hwan Kim Dong Heon Kim Cheol Woong Choi Jeong Heo Geun Am Song | 2009 | World Journal of Gastroenterology2009,15,27: | 12 |
| 3 | Associated factors for a hyperechogenic pancreas on endoscopic ultrasound显示文摘AIM: To identify the associated risk factors for hyperechogenic pancreas (HP) which may be observed on endoscopic ultrasound (EUS) and to assess the relationship between HP and obesity. METHODS: From January 2007 to December 2007, we prospectively enrolled 524 consecutive adults who were scheduled to undergo EUS. Patients with a history of pancreatic disease or with hepatobiliary or advanced gastrointestinal cancer were excluded. Finally,284 patients were included in the analyses. We further analyzed the risk of HP according to the categories of visceral adipose tissue (VAT) and subcutaneous adipose tissue in 132 patients who underwent abdominal computed tomography scans. RESULTS: On univariate analysis, age older than 60 years, obesity (body mass index > 25 kg/m 2 ), fatty liver, diabetes mellitus, hypertension and hypercholesterolemia were identified as risk factors associated with HP (P < 0.05). On multivariate analysis, fatty liver [P = 0.008, odds ratio (OR) = 2.219], male gender (P = 0.013, OR = 2.636), age older than 60 years (P = 0.001, OR = 2.874) and hypertension (P = 0.044, OR = 2.037) were significantly associated with HP. In the subgroup analysis, VAT was a statistically significant risk factor for HP (P = 0.010, OR = 5.665, lowest quartile vs highest quartile). CONCLUSION: HP observed on EUS was associated with fatty liver, male gender, age older than 60 years, hypertension and VAT. | Cheol Woong Choi Gwang Ha Kim Dae Hwan Kang Hyung Wook Kim Dong Uk Kim Jeong Heo Geun Am Song Do Youn Park Suk Kim | 2010 | World Journal of Gastroenterology2010,16,34: | 8 |
| 4 | Is obesity associated with gastropharyngeal reflux disease?显示文摘AIM: To examine the association between obesity and gastropharyngeal reflux disease (GPRD) as well as gastroesophageal reflux disease (GERD) METHODS: We conducted a cross-sectional study of consecutive patients undergoing ambulatory 24-h dual-probe pH monitoring from July 2003 to December 2006. The association between body mass index (BMI) and parameters about gastroesophageal or gastropharyngeal reflux was examined in univariate and multivariate analyses.RESULTS: A total of 769 patients (307 men and 462 women; mean age 50.7 years) were finally enrolled. Most variables showing gastroesophageal reflux was higher in the obese patients than the patients with normal BMI. There was no difference in all the variables showing gastropharyngeal reflux according to the BMI. After adjustment for age, sex, alcohol intake and smoking, obese patients demonstrated an about 2-fold increase in risk of GERD compared with patients with normal BMI (OR, 1.9; 95 CI, 1.3-2.9), but overweight patients did not demonstrate increased risk of GERD (OR, 1.2; 95 CI, 0.8-1.7). Both obese patients and overweight patients did not demonstrated increased risk of GPRD compared with patients with normal BMI (OR, 1.1; 95 CI, 0.8-1.7; and OR, 0.9; 95 CI, 0.6-1.3, respectively).CONCLUSION: Obesity is not associated with GPRD reflux while it is associated with GERD. | Cheol Woong Choi Gwang Ha Kim Chul Soo Song Soo Geun Wang Byung Joo Lee Hoseok I Dae Hwan Kang Geun Am Song | 2008 | World Journal of Gastroenterology2008,14,2: | 5 |
| 5 | Needle-knife fistulotomy vs double-guidewire technique in patients with repetitive unintentional pancreatic cannulations显示文摘AIM: To compare the success rates and adverse events of early needle-knife fistulotomy(NKF) and double-guidewire technique(DGT) in patients with repetitive unintentional pancreatic cannulations.METHODS: From a total of 1650 patients admitted for diagnostic or therapeutic endoscopic retrograde cholangiopancreatography(ERCP) at a single tertiary care hospital(Pusan National University Yangsan Hospital, Yangsan, South Korea) between January2009 and December 2012, 134(8.1%) patients with unsuccessful biliary cannulation after 5 min trial of conventional methods, together with 5 or more repetitive unintentional pancreatic cannulations, were enrolled in the study. Early NKF and DGT groups were assigned 67 patients each. In the DGT group, NKF was performed for an additional 7 min if successful cannulation was not achieved.RESULTS: The success rates with early NKF andthe DGT were 79.1%(53/67) and 44.8%(30/67)(P< 0.001), respectively. The incidence of post-ERCP pancreatitis(PEP) was lower in the early NKF group than in the DGT group [4.5%(3/67) vs 14.9%(10/67),P = 0.041]. The mean cannulation times in the early NKF and DGT groups after assignment were 257 s and312 s(P = 0.013), respectively.CONCLUSION: Our data suggest that early NKF should be considered as the first approach to selective biliary cannulation in patients with repetitive unintentional pancreatic cannulations. | Su Jin Kim Dae Hwan Kang Hyung Wook Kim Cheol Woong Choi Su Bum Park Byeong Jun Song Young Mi Hong | 2015 | World Journal of Gastroenterology2015,21,19: | 4 |
| 6 | Acute idiopathic pancreatitis in pregnancy:A case study显示文摘Acute pancreatitis during pregnancy is a rare event,and can be associated with high maternal mortality and fetal loss.Gallstone disease is thought to be the most common causative factor of acute pancreatitis,but,in many cases,the cause remains unclear.We report a case of a 36-year-old woman at 35 wk of gestation,who presented with severe pain confined to the upper abdomen and radiating to the back.The patient was diagnosed with acute idiopathic pancreatitis,which was managed conservatively;she recovered within several days and then delivered a healthy baby.Therefore it is important to consider acute pancreatitis when a pregnant woman presents with upper abdominal pain,nausea and vomiting in order to improve fetal and maternal outcomes for patients with acute pancreatitis. | Ji Yeon Kim Sung Hoon Jung Hyung Wook Choi Dong Jin Song Cheol Yoon Jeong Dong Hyun Lee Il Soon Whang | 2014 | World Journal of Gastroenterology2014,20,43: | 4 |

| 8 | Effects of lysophosphatidic acid on human periodontal ligament stem cells from teeth extracted from dental patients显示文摘Despite their potential applications in future regenerative medicine, periodontal ligament stem cells(PDLSCs) are difficult to obtain in large amounts from patients. Therefore, maintaining sternness while expanding the cell numbers for medical use is the key to transitioning PDLSCs from the bench to the clinic. Lysophosphatidic acid(LPA), which is present in the human body and saliva, is a signaling molecule derived from phospholipids. In this study, we examined the effects of LPA on sternness maintenance in human PDLSCs. Several spindle-shaped and fibroblast-like periodontal ligament stem-like cell lines were established from PDLSC isolation. Among these cell lines, the most morphologically appropriate cell line was characterized. The expression levels of OCT4, NANOG(a stem cell marker), and CD90(a mesenchymal stem cell marker) were high. However, CD73(a negative marker of mesenchymal stem cells) expression was not observed. Notably, immunofluorescence analysis identified the expression of STRO-1, CD146(a mesenchymal stem cell marker), and sex determining region Y-box 2 at the protein level. In addition, lipid droplets were stained by Oil red O after the induction of adipogenesis for 21 days, and mineralized nodules were stained by Alizarin Red S after the induction of osteogenesis for 14 days. Alkaline phosphate staining also demonstrated the occurrence of osteogenesis. In summary, we established a human PDLSC line, which could be applied as a cell source for tissue regeneration in dental patients. However, further studies are needed to determine the detailed effects of LPA on PDLSCs. | Byung Cheol Kim Jae-In Song Kyoung-Ha So Sang-Hwan Hyun | 2019 | The Journal of Biomedical Research2019,33,2: | 3 |
| 9 | Time-course pattern of neuronal loss and gliosis in gerbil hippocampi following mild, severe, or lethal transient global cerebral ischemia显示文摘Transient ischemia in the whole brain leads to neuronal loss/death in vulnerable brain regions. The striatum, neocortex and hippocampus selectively loose specific neurons after transient ischemia. Just 5 minutes of transient ischemia can cause pyramidal neuronal death in the hippocampal cornu ammonis (CA) 1 field at 4 days after transient ischemia. In this study, we investigated the effects of 5-minute (mild), 15-minute (severe), and 20-minute (lethal) transient ischemia by bilateral common carotid artery occlusion (BCCAO) on behavioral change and neuronal death and gliosis (astrocytosis and microgliosis) in gerbil hippocampal subregions (CA1-3 region and dentate gyrus). We performed spontaneous motor activity test to evaluate gerbil locomotor activity, cresyl violet staining to detect cellular distribution, neuronal nuclei immunohistochemistry to detect neuronal distribution, and Fluoro-Jade B histofluorescence to evaluate neuronal death. We also conducted immunohistochemical staining for glial fibrillary acidic protein and ionized calcium-binding adapter molecule 1 (Ibal) to evaluate astrocytosis and microgliosis, respectively. Animals subjected to 20-minute BCCAO died in at least 2 days. BCCAO for 15 minutes led to pyramidal cell death in hippocampal CA1-3 region 2 days later and granule cell death in hippocampal de匚tate gyrus 5 days later. Similar results were not found in animals subjected to 5-minute BCCAO. Gliosis was much more rapidly and severely progressed in animals subjected to 15-minute BCCAO than in those subjected to 5- minute BCCAO. Our results indicate that neuronal loss in the hippocampal formation following transient ischemia is significantly different according to regions and severity of transient ischemia. The experimental protocol was approved by Institutional Animal Care and Use Committee (AICUC) of Kangwon National University (approval No. KW-180124-1) on May 22, 2018. | Tae-Kyeong Lee Hyunjung Kim Minah Song Jae-Chul Lee Joon Ha Park Ji Hyeon Ahn Go Eun Yang Hyeyoung Kim Taek Geun Ohk Myoung Cheol Shin Jun Hwi Cho Moo-Ho Won | 2019 | Neural Regeneration Research2019,14,8: | 3 |
| 10 | RGD peptide and graphene oxide co-functionalized PLGA nanofiber scaffolds for vascular tissue engineering显示文摘In recent years,much research has been suggested and examined for the development of tissue engineering scaffolds to promote cellular behaviors.In our study,RGD peptide and graphene oxide(GO)co-functionalized poly(lactide-co-glycolide,PLGA)(RGD-GO-PLGA)nanofiber mats were fabricated via electrospinning,and their physicochemical and thermal properties were characterized to explore their potential as biofunctional scaffolds for vascular tissue engineering.Scanning electron microscopy images revealed that the RGD-GO-PLGA nanofiber mats were readily fabricated and composed of randomoriented electrospun nanofibers with average diameter of 558nm.The successful co-functionalization of RGD peptide and GO into the PLGA nanofibers was confirmed by Fourier-transform infrared spectroscopic analysis.Moreover,the surface hydrophilicity of the nanofiber mats was markedly increased by co-functionalizing with RGD peptide and GO.It was found that the mats were thermally stable under the cell culture condition.Furthermore,the initial attachment and proliferation of primarily cultured vascular smoothmuscle cells(VSMCs)on the RGD-GO-PLGA nanofibermats were evaluated.It was revealed that the RGD-GO-PLGA nanofibermats can effectively promote the growth of VSMCs.In conclusion,our findings suggest that the RGD-GO-PLGA nanofiber mats can be promising candidates for tissue engineering scaffolds effective for the regeneration of vascular smooth muscle. | Yong Cheol Shin Jeonghyo Kim Sung Eun Kim Su-Jin Song SuckWon Hong Jin-Woo Oh Jaebeom Lee Jong-Chul Park Suong-Hyu Hyon Dong-Wook Han | 2017 | Regenerative Biomaterials2017,4,3: | 3 |

| 12 | Moxifloxacin-containing triple therapy after non-bismuth quadruple therapy failure for Helicobacter pylori infection显示文摘AIM: To assess the efficacy of moxifloxacin-containing triple therapy after non-bismuth quadruple therapy failure for Helicobacter pylori(H. pylori) eradication.METHODS: Between January 2010 and December 2012,we screened individuals who were prescribed non-bismuth quadruple therapy for H. pylori eradication. Among them,a total of 98 patients who failed non-bismuth quadruple therapy received 1-wk or 2-wk moxifloxacin-containing triple therapy(400 mg moxifloxacin once daily,and 20 mg of rabeprazole and 1 g of amoxicillin twice daily). H. pylori status was evaluated using the 13C-urea breath test 4 wk later,after treatment completion. The eradication rates were determined by intention-to-treat and per-protocol analyses.RESULTS: In total,60 and 38 patients received 1-wk and 2-wk moxifloxacin-containing triple therapy,respectively. The intention-to-treat and per-protocol eradication rates were 56.7%(95%CI: 45.0-70.0) and 59.6%(95%CI: 46.6-71.7) in the 1-wk group and 76.3%(95%CI: 63.2-89.5) and 80.6%(95%CI: 66.7-91.9) in the 2-wk group(P = 0.048 and 0.036,respectively). All groups had good compliance(95% vs 94.9%). Neither group showed serious adverse events,and the proportions of patients experiencing mild side effects were not significantly different(21.1% vs 13.9%). Clinical factors such as age,sex,alcohol and smoking habits,comorbidities,and presence of gastric or duodenal ulcer did not influence the eradication therapy efficacy. The efficacy of second-line eradication therapy did not differ significantly according to the firstline regimen.CONCLUSION: Two-week moxifloxacin-containing triple therapy showed better efficacy than a 1-wk regimen after non-bismuth quadruple therapy failure.Key words: Helicobacter pylori; Moxifloxacin-based triple; Non-bismuth quadruple; Second-line; | Ji Hyun Lim Dong Ho Lee Seong Tae Lee Nayoung Kim Young Soo Park Cheol Min Shin In Sung Song | 2015 | World Journal of Gastroenterology2015,21,46: | 2 |

| 15 | Modeling and implementation of tandem polymer solar cells using wide-bandgap front cells显示文摘Tandem device architectures offer a route to greatly increase the maximum possible power conversion efficiencies(PCEs)of polymer solar cells,however,the complexity of tandem cell device fabrication(such as selecting bandgaps of the front and back cells,current matching,thickness,and recombination layer optimization)often result in lower PCEs than are observed in single-junction devices.In this study,we analyze the influence of front cell and back cell bandgaps and use transfer matrix modeling to rationally design and optimize effective tandem solar cell structures before actual device fabrication.Our approach allows us to estimate tandem device parameters based on known absorption coefficients and open-circuit voltages of different active layer materials and design devices without wasting valuable time and materials.Using this approach,we have investigated a series of wide bandgap,high voltage photovoltaic polymers as front cells in tandem devices with PTB7-Th as a back cell.In this way,we have been able to demonstrate tandem devices with PCE of up to 12.8%with minimal consumption of valuable photoactive materials in tandem device optimization.This value represents one of the highest PCE values to date for fullerene-based tandem solar cells. | Seo-Jin Ko Hyosung Choi Quoc Viet Hoang Chang Eun Song Pierre-Olivier Morin Jungwoo Heo Mario Leclerc Sung Cheol Yoon Han Young Woo Won Suk Shin Bright Walker Jin Young Kim | 2020 | Carbon Energy2020,2,1: | 2 |
