| 1 | Clinicopathologic significance of expression of nuclear factor-kB RelA and its target gene products in gastric cancer patients显示文摘AIM:To assess the prognostic significance of nuclear factor-kB (NF-kB) and its target genes in gastric cancer. METHODS:The tumor tissues of 115 patients with gastric cancer were immunohistochemically evaluated using monoclonal antibodies against NF-kB RelA. Preoperative serum levels of vascular endothelial growth factor (VEGF), interleukin-6 (IL-6) were assessed via enzyme-linked immuno-sorbent assay. C-reactive protein (CRP) and serum amyloid A (SAA) were measured via immunotrubidimetry. RESULTS:Positive rate of NF-kB RelA was 42.6%. NF-kB RelA expression in tumor tissues was also related to serum levels of IL-6 (P = 0.044) and CRP (P = 0.010). IL-6, SAA, CRP were related to depth of invasion, VEGF and SAA were correlated with lymph node metastasis. IL-6, VEGF, SAA and CRP were related to the stage. Univariate analysis demonstrated that immunostaining of NF-kB RelA, levels of IL-6, VEGF, SAA were significantly related with both disease free survival and over-all survival (OS). Multivariate analysis verified that NF-kB RelA [hazard ratio (HR): 3.40, P = 0.024] and SAA (HR: 3.39, P = 0.045) were independently associated with OS. CONCLUSION: Increased expression of NF-kB RelA and high levels of serum SAA were associated with poor OS in gastric cancer patients. | Hyuk-Chan Kwon Sung-Hyun Kim Sung Yong Oh Suee Lee Ji Hyun Lee Jin Seok Jang Min Chan Kim Ki Han Kim Su-Jin Kim Seong-Geun Kim Hyo-Jin Kim | 2012 | World Journal of Gastroenterology2012,18,34: | 9 |
| 2 | Peer-assisted learning to train high-school students to perform basic life-support显示文摘BACKGROUND: The inclusion of cardiopulmonary resuscitation(CPR) in formal education has been a useful approach to providing basic life support(BLS) services. However, because not all students have been able to learn directly from certified instructors, we studied the educational efficacy of the use of peer-assisted learning(PAL) to train high-school students to perform BLS services.METHODS: This study consisted of 187 high-school students: 68 participants served as a control group and received a 1-hour BLS training from a school nurse, and 119 were included in a PAL group and received a 1-hour CPR training from a PAL leader. Participants' BLS training was preceded by the completion of questionnaires regarding their background. Three months after the training, the participants were asked to respond to questionnaires about their willingness to perform CPR on bystander CPR and their retention of knowledge of BLS.RESULTS: We found no statistically significant difference between the control and PAL groups in their willingness to perform CPR on bystanders(control: 55.2%, PAL: 64.7%, P=0.202). The PAL group was not significantly different from the control group(control: 60.78±39.77, PAL: 61.76±17.80, P=0.848) in retention of knowledge about BLS services.CONCLUSION: In educating high school students about BLS, there was no significant difference between PAL and traditional education in increasing the willingness to provide CPR to bystanders or the ability to retain knowledge about BLS. | Hyung Soo Choi Dong Hoon Lee Chan Woong Kim Sung Eun Kim Je Hyeok Oh | 2015 | World Journal of Emergency Medicine2015,6,3: | 6 |
| 3 | Is the AIM65 score useful in predicting outcomes in peptic ulcer bleeding?显示文摘AIM:To evaluate the applicability of AIMS65 scores in predicting outcomes of peptic ulcer bleeding.METHODS:This was a retrospective study in a single center between January 2006 and December 2011.We enrolled 522 patients with upper gastrointestinal haemorrhage who visited the emergency room.Highrisk patients were regarded as those who had rebleeding within 30 d from the first endoscopy as well as those who died within 30 d of visiting the Emergency room.A total of 149 patients with peptic ulcer bleeding were analysed,and the AIMS65 score was used to retrospectively predict the high-risk patients.RESULTS:A total of 149 patients with peptic ulcer bleeding were analysed.The poor outcome group comprised 28 patients[male:23(82.1%)vs female:5(10.7%)]while the good outcome group included 121patients[male:93(76.9%)vs female:28(23.1%)].The mean age in each group was not significantly different.The mean serum albumin levels in the poor outcome group were slightly lower than those in the good outcome group(P=0.072).For the prediction of poor outcome,the AIMS65 score had a sensitivity of35.5%(95%CI:27.0-44.8)and a specificity of 82.1%(95%CI:63.1-93.9)at a score of 0.The AIMS65 score was insufficient for predicting outcomes in peptic ulcer bleeding(area under curve=0.571;95%CI:0.49-0.65).CONCLUSION:The AIMS65 score may therefore not be suitable for predicting clinical outcomes in peptic ulcer bleeding.Low albumin levels may be a risk factor associated with high mortality in peptic ulcer bleeding. | Sung Hoon Jung Jung Hwan Oh Hye Yeon Lee Joon Won Jeong Se Eun Go Chan Ran You Eun Jung Jeon Sang Wook Choi | 2014 | World Journal of Gastroenterology2014,20,7: | 6 |

| 5 | Nutrient supplemented serum-free medium increases cardiomyogenesis efficiency of human pluripotent stem cells显示文摘AIM: To development of an improved p38 MAPK inhibitor-based serum-free medium for embryoid body cardiomyocyte differentiation of human pluripotent stem cells. METHODS: Human embryonic stem cells (hESC) differentiated to cardiomyocytes (CM) using a p38 MAPK inhibitor (SB203580) based serum-free medium (SB media). Nutrient supplements known to increase cell viability were added to SB medium. The ability of these supplements to improve cardiomyogenesis was evaluated by measurements of cell viability, total cell count, and the expression of cardiac markers via flow cytometry. An improved medium containing Soy hydrolysate (HySoy) and bovine serum albumin (BSA) (SupSB media) was developed and tested on 2 additional cell lines (H1 and Siu-hiPSC). Characterization of the cardiomyocytes was done by immunohistochemistry, electrophysiology and quantitative real-time reverse transcriptionpolymerase chain reaction. RESULTS: hESC cell line, HES-3, differentiating in SB medium for 16 d resulted in a cardiomyocyte yield of 0.07 ± 0.03 CM/hESC. A new medium (SupSB media) was developed with the addition of HySoy and BSA to SB medium. This medium resulted in 2.6 fold increase in cardiomyocyte yield (0.21 ± 0.08 CM/hESC). The robustness of SupSB medium was further demonstrated using two additional pluripotent cell lines (H1, hESC and Siu1, hiPSC), showing a 15 and 9 fold increase in cardiomyocyte yield respectively. The age (passage number) of the pluripotent cells did not affect the cardiomyocyte yields. Embryoid body (EB) cardiomyocytes formed in SupSB medium expressed canonical cardiac markers (sarcomeric α-actinin, myosin heavy chain and troponin-T) and demonstrated all three major phenotypes: nodal-, atrial- and ventricular-like. Electrophysiological characteristics (maximum diastolic potentials and action potential durations) of cardiomyocytes derived from SB and SupSB media were similar. CONCLUSION: The nutrient supplementation (HySoy and BSA) leads to increase in cell viability, cell yield and cardiac marker expression during cardiomyocyte differentiation, translating to an overall increase in cardiomyocyte yield. | Sherwin Ting Marti Lecina Yau-Chi Chan Hung Fat Tse Shaul Reuveny Steve KW Oh | 2013 | World Journal of Stem Cells2013,5,3: | 4 |
| 6 | Bevacizumab as a second- or later-line of treatment for metastatic colorectal cancer显示文摘AIM: To determine the efficacy of bevacizumab in patients with metastatic colorectal cancer (MCRC) who have failed prior chemotherapy without bevacizumab. METHODS: Between March 2002 and June 2010, 40 patients in South Korea with MCRC who were treated with bevacizumab plus chemotherapy as a second or later-line treatment were analyzed retrospectively for their overall response rate (ORR), overall survival (OS), and progression-free survival (PFS). The tumor responses were assessed using the RECIST (Response Evaluation Criteria in Solid Tumors) guidelines. RESULTS: All of the patients had progressed under prior chemotherapy without bevacizumab. Three patients (7.5%) exhibited an ORR, twenty one patients (52.5%) exhibited stable disease (SD), and fifteen patients (37.5%) exhibited disease progression. The median duration of the OS and PFS were 14.0 and 6.13 mo respectively. The median OSs were 16.60, 14.07 and 13.00 mo for second-line, third-line and fourth- or later-line treatments, respectively. The median PFSs were 7.23, 7.30 and 3.87 mo for the second-line, third-line and fourth- or later-line treatments, respectively. CONCLUSION: In patients with MCRC, bevacizumab combined chemotherapy may be beneficial during second- or later-line treatment. | Lee Chun Park Ho Sup Lee Seong Hoon Shin Seun Ja Park Moo In Park Sung Yong Oh Hyuk Chan Kwon Jin ho Baek Young Jin Choi Myoung Joo Kang Yang Soo Kim | 2012 | World Journal of Gastroenterology2012,18,10: | 3 |

| 8 | Diabetic factors associated with gastrointestinal symptoms in patients with type 2 diabetes显示文摘AIM: To determine whether gastrointestinal (GI) symptoms are more frequent in type 2 diabetic patients and to examine which diabetic factors are associated with the symptoms. METHODS: Consecutive subjects with diabetes and age-/gender-matched normal controls were recruited for this study. GI symptoms were assessed using a structured questionnaire divided into two GI symptomcategories (upper and lower GI symptoms), and consisting of 11 individual symptoms. In the diabetic patient group, diabetic complications including peripheral neuropathy, nephropathy and retinopathy, glycosylated hemoglobin (HbA1c) level and diabetes duration were evaluated. RESULTS: Among the total 190 diabetic patients and 190 controls enrolled, 137 (72%) of the diabetic patients and 116 (62%) of the controls had GI symptoms. In the diabetic patient group, 83 (43%) had upper GI symptoms and 110 (58%) lower GI symptoms; in the control group, 59 (31%) had upper GI symptoms and 104 (55%) lower GI symptoms. This difference between the two groups was significant for only the upper GI symptoms (P = 0.02). Among the diabetic factors, the HbA1c level was the only independent risk factor for upper GI symptoms in the multiple logistic regression analysis (odds ratio = 2.01, 95% confidence interval: 1.02-3.95). CONCLUSION: Type 2 diabetes was associated with an increased prevalence of upper GI symptoms and these symptoms appeared to be independently linked to poor glycemic control, as measured by the HbA1c levels. | Jeong Hwan Kim Hyung Seok Park Soon Young Ko Sung Noh Hong In-Kyung Sung Chan Sub Shim Kee-Ho Song Dong-Lim Kim Sook Kyung Kim Jeeyoung Oh | 2010 | World Journal of Gastroenterology2010,16,14: | 3 |
| 9 | A MEMS ultrasound stimulation system for modulation of neural circuits with high spatial resolution in vitro显示文摘Neuromodulation by ultrasound has recently received attention due to its noninvasive stimulation capability for treating brain diseases.Although there have been several studies related to ultrasonic neuromodulation,these studies have suffered from poor spatial resolution of the ultrasound and low repeatability with a fixed condition caused by conventional and commercialized ultrasound transducers.In addition,the underlying physics and mechanisms of ultrasonic neuromodulation are still unknown.To determine these mechanisms and accurately modulate neural circuits,researchers must have a precisely controllable ultrasound transducer to conduct experiments at the cellular level.Herein,we introduce a new MEMS ultrasound stimulation system for modulating neurons or brain slices with high spatial resolution.The piezoelectric micromachined ultrasonic transducers(pMUTs)with small membranes(submm membranes)generate enough power to stimulate neurons and enable precise modulation of neural circuits.We designed the ultrasound transducer as an array structure to enable localized modulation in the target region.In addition,we integrated a cell culture chamber with the system to make it compatible with conventional cell-based experiments,such as in vitro cell cultures and brain slices.In this work,we successfully demonstrated the functionality of the system by showing that the number of responding cells is proportional to the acoustic intensity of the applied ultrasound.We also demonstrated localized stimulation capability with high spatial resolution by conducting experiments in which cocultured cells responded only around a working transducer. | Jungpyo Lee Kyungmin Ko Hyogeun Shin Soo-Jin Oh CJustin Lee Namsun Chou Nakwon Choi Min Tack Oh Byung Chul Lee Seong Chan Jun Il-Joo Cho | 2019 | Microsystems & Nanoengineering2019,5,1: | 3 |

| 13 | Bisphosphonate use and gastrointestinal tract cancer risk:Meta-analysis of observational studies显示文摘AIM:To perform a meta-analysis of observational studies to further elucidate the relationship between oral bisphosphonate use and gastrointestinal cancer risk.METHODS:Systematic literature search was conducted in MEDLINE,EMBASE,and the Cochrane Library to identify studies through January 2011.Search terms were 'bisphosphonates' or trade names of the drugs,and 'observational studies' or 'cohort studies' or 'case-control studies'.Two evaluators reviewed and selected articles on the basis of predetermined selection criteria as followed:(1) observational studies(casecontrol or cohort studies) on bisphosphonate use;(2) with at least 2 years of follow-up;and(3) reported data on the incidence of cancer diagnosis.The DerSimonian and Laird random effects model were used to calculate the pooled relative risk(RR) with 95% confidence interval(CI).Two-by-two contingency table was used to calculate the outcomes not suitable for meta-analysis.Subgroup meta-analyses were conducted for the type of cancer(esophageal,gastric and colorectal cancers).Sensitivity analyses were performed to examine the effect sizes when only studies with long-term follow-up(mean 5 years;subgroup 3 years) were included.RESULTS:Of 740 screened articles,3 cohort studies and 3 case-control studies were included in the analyses.At first,4 cohort studies and 3 case-control studies were selected for the analyses but one cohort study was excluded because the cancer outcomes were not categorized by type of gastrointestinal cancer.More than 124 686 subjects participated in the 3 cohort studies.The mean follow-up time in all of the cohort studies combined was approximately 3.88 years.The 3 casecontrol studies reported 3070 esophageal cancer cases and 15 417 controls,2018 gastric cancer cases and 10 007 controls,and 11 574 colorectal cancer cases and 53 955 controls.The percentage of study participants who used bisphosphonate was 2.8% among the cases and 2.9% among the controls.The meta-analysis of all the studies found no significant association between bisphosphonate use and gastrointestinal cancer.Also no statistically significant association was found in a meta-analysis of long-term follow-up studies.There was no negative association between bisphosphonate use and the incidence of esophageal cancer in the overall analysis(RR 0.96,95% CI:0.65-1.42,I 2 = 52.8%,P = 0.076) and no statistically significant association with long-term follow-up(RR 1.74,95% CI:0.97-3.10,I 2 = 58.8%,P = 0.119).No negative association was found in the studies reporting the risk of gastric cancer(RR 0.89,95% CI:0.71-1.13,I 2 = 0.0%,P = 0.472).In case of colorectal cancer,there was no association between colorectal cancer and bisphosphonate use(RR 0.62,95% CI:0.30-1.29,I 2 = 88.0%,P = 0.004) and also in the analysis with long-term follow-up(RR 0.61,95% CI:0.28-1.35,I 2 = 84.6%,P = 0.011).CONCLUSION:Oral bisphosphonate use had no significant effect on gastrointestinal cancer risk.However,this finding should be validated in randomized controlled trials with long-term follow-up. | Yun Hwan Oh Chan Yoon Sang Min Park | 2012 | World Journal of Gastroenterology2012,18,40: | 2 |
