| 1 | Nutritional risk index as a predictor of postoperative wound complications after gastrectomy显示文摘AIM:To investigate the correlation between the nutritional risk index (NRI) and postoperative wound complications.METHODS:From January 2008 through June 2008,669 patients who underwent curative gastrectomy for gastric cancer were included in a retrospective study.Medical records of consecutive patients were collected and analyzed to determine postoperative wound complication rates.The NRI was assessed on the fifth postoperative day and other possible risk factors for the incidence of wound complications were analyzed to identify the factors affecting postoperative wound complications.Patients with other postoperative complications were excluded from the study.RESULTS:On the 5th postoperative day,the NRI showed a malnutrition rate of 84.6% among postoperative patients.However,postoperative wound complications occurred in only 66/669 (9.86%) patients.Of the patients with wound complications,62/66 (94%) belonged to the malnourished group (NRI < 97.5),and 4/66 (6%) patients to the non-malnourished group (NRI ≥ 97.5).The only factor correlated with wound complications was the NRI on the 5th postoperative day (odds ratio of NRI ≥ 97.5 vs NRI < 97.5:0.653;95% confidence interval:0.326-0.974;P=0.014) according to univariate analysis as well as multivariate analysis.CONCLUSION:This study suggests that malnutrition immediately after surgery may play a significant role in the development of wound complications. | Cheong Ah Oh Dae Hoon Kim Seung Jong Oh Min Gew Choi Jae Hyung Noh Tae Sung Sohn Jae Moon Bae Sung Kim | 2012 | World Journal of Gastroenterology2012，18，7： | 25 |
| 2 | Real time shear wave elastography in chronic liver diseases:Accuracy for predicting liver fibrosis,in comparison with serum markers显示文摘AIM:To evaluate the correlation between liver stiffness measurement(LSM)by real-time shear wave elastography(SWE)and liver fibrosis stage and the accuracy of LSM for predicting significant and advanced fibrosis,in comparison with serum markers.METHODS:We consecutively analyzed 70 patients with various chronic liver diseases.Liver fibrosis was staged from F0 to F4 according to the Batts and Ludwig scoring system.Significant and advanced fibrosis was defined as stage F≥2 and F≥3,respectively.The accuracy of prediction for fibrosis was analyzed using receiver operating characteristic curves.RESULTS:Seventy patients,15 were belonged to F0-F1 stage,20 F2,13 F3 and 22 F4.LSM was increased with progression of fibrosis stage(F0-F1:6.77±1.72,F2:9.98±3.99,F3:15.80±7.73,and F4:22.09±10.09,P<0.001).Diagnostic accuracies of LSM for prediction of F≥2 and F≥3 were 0.915(95%CI:0.824-0.968,P<0.001)and 0.913(95%CI:0.821-0.967,P<0.001),respectively.The cut-off values of LSM for prediction of F≥2 and F≥3 were 8.6kPa with 78.2%sensitivity and 93.3%specificity and10.46 kPa with 88.6%sensitivity and 80.0%specificity,respectively.However,there were no significant differences between LSM and serum hyaluronic acid and typeⅣcollagen in diagnostic accuracy.CONCLUSION:SWE showed a significant correlation with the severity of liver fibrosis and was useful and accurate to predict significant and advanced fibrosis,comparable with serum markers. | Jae Yoon Jeong Tae Yeob Kim Joo Hyun Sohn Yongsoo Kim Woo Kyoung Jeong Young-Ha Oh Kyo-Sang Yoo | 2014 | World Journal of Gastroenterology2014，20，38： | 19 |
| 3 | Recurrence after endoscopic piecemeal mucosal resection for large sessile colorectal polyps显示文摘AIM: To evaluate the safety and outcomes of endoscopic piecemeal mucosal resection (EPMR) for large sessile colorectal polyps. METHODS: The patients enrolled in this study were 47 patients with 50 large sessile polyps (diameter, 2 cm or greater) who underwent EPMR using a submucosal saline injection technique between December 2002 and October 2005. All medical records, including characteristics of the patients and polyps, complications, and recurrences, were retrospectively reviewed. The first follow-up endoscopic examination was performed at 3-6 mo after initial endoscopic resection, and the second at 12 mo postEPMR. Subsequent surveillance colonoscopic examinations were individualized, taking risk factors into account. RESULTS: The patients were 23 men and 24 women,with a mean age of 60 years. Mean polyp size was 30.1 mm. Of 50 polyps identified, 34 (68%) were benign and 16 (32%) were malignant. There were 6 (12%) cases with EPMR-related bleeding: 5 intra-procedural and 1 early post-procedural bleeding. All bleeding episodes were managed by endoscopic clipping or argon beam coagulation. There were no perforations. Recurrence was identified in 5 cases (12.2%): 4 local recurrences detected at 3 mo post-EPMR and 1 local recurrence detected at 14 mo post-EPMR. The recurrence rate after EPMR was 3.1% for benign polyps and 33.3% for malignant polyps (P < 0.05). Median follow-up time was 37 mo. CONCLUSION: EPMR is safe, but should be applied carefully in malignant polyps. Close follow-up endoscopic examinations are necessary for early detection of recurrence. | Guh Jung Seo Dae Kyung Sohn Kyung Su Han Chang Won Hong Byung Chang Kim Ji Won Park Hyo Seong Choi Hee Jin Chang Jae Hwan Oh | 2010 | World Journal of Gastroenterology2010，16，22： | 17 |
| 4 | Endoscopic ultrasound-guided biliary drainage with placement of a fully covered metal stent for malignant biliary obstruction显示文摘AIM:To determine the utility of endoscopic ultrasoundguided biliary drainage(EUS-BD)with a fully covered self-expandable metal stent for managing malignant biliary stricture. METHODS:We collected data from 13 patients who presented with malignant biliary obstruction and underwent EUS-BD with a nitinol fully covered selfexpandable metal stent when endoscopic retrograde cholangiopancreatography(ERCP)fails.EUS-guided choledochoduodenostomy(EUS-CD)and EUS-guided hepaticogastrostomy(EUS-HG)was performed in 9 patients and 4 patients,respectively. RESULTS:The technical and functional success rate was 92.3%(12/13)and 91.7%(11/12),respectively. Using an intrahepatic approach(EUS-HG,n=4),there was mild peritonitis(n=1)and migration of the metal stent to the stomach(n=1).With an extrahepatic approach(EUS-CD,n=10),there was pneumoperitoneum(n=2),migration(n=2),and mild peritonitis (n=1).All patients were managed conservatively with antibiotics.During follow-up(range,1-12 mo),there was re-intervention(4/13 cases,30.7%)necessitated by stent migration(n=2)and stent occlusion(n=2). CONCLUSION:EUS-BD with a nitinol fully covered self-expandable metal stent may be a feasible and effective treatment option in patients with malignant biliary obstruction when ERCP fails. | Tae Hyeon Kim Seong Hun Kim Hyo Jeong Oh Young Woo Sohn Seung Ok Lee | 2012 | World Journal of Gastroenterology2012，18，20： | 16 |

| 7 | Anti-inflammatory and Antimicrobial Effects of Anthocyanin Extracted from Black Soybean on Chronic Bacterial Prostatitis Rat Model显示文摘Objective: To investigated the anti-inflammatory and antimicrobial effects of anthocyanins extracted from black soybean on the chronic bacterial prostatitis(CBP) rat model.Methods: The SpragueDawley rats were divided into 4 groups,including control,ciprofloxacin,anthocyanins and anthocyanins with ciprofloxacin groups(n=8 in each group).Then,drip infusion of bacterial suspension(Escherichia coli Z17O_2:K_1:H^-) into Sprague-Dawley rats was conducted to induce CBP.In 4 weeks,results of prostate tissue,urine culture,and histological analysis on the prostate were analyzed for each group.Results: The use of ciprofloxacin,anthocyanins,and anthocyanins with ciprofloxacin showed statistically significant decreases in bacterial growth and improvements in the reduction of prostatic inflammation compared with the control group(P<0.05).The anthocyanins with ciprofloxacin group showed a statistically significant decrease in bacterial growth and improvement in prostatic inflammation compared with the ciprofloxacin group(P<0.05).Conclusions: These results suggest that anthocyanins may have anti-inflammatory and antimicrobial effects,as well as a synergistic effect with ciprofloxacin.Therefore,we suggest that the combination of anthocyanins and ciprofloxacin may be effective in treating CBP to obtain a higher rate of treatment success. | Byung Il Yoon Woong Jin Bae Yong Sun Choi Su Jin Kim U Syn Ha Sung-Hoo Hong Dong Wan Sohn Sae Woong Kim | 2018 | Chinese Journal of Integrative Medicine2018，24，8： | 11 |
| 8 | Efficacy 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 | 2014 | Journal of Traditional Chinese Medicine2014，34，5： | 11 |
| 9 | Understanding the physical metallurgy of the CoCrFeMnNi high-entropy alloy:an atomistic simulation study显示文摘Although high-entropy alloys(HEAs)are attracting interest,the physical metallurgical mechanisms related to their properties have mostly not been clarified,and this limits wider industrial applications,in addition to the high alloy costs.We clarify the physical metallurgical reasons for the materials phenomena(sluggish diffusion and micro-twining at cryogenic temperatures)and investigate the effect of individual elements on solid solution hardening for the equiatomic CoCrFeMnNi HEA based on atomistic simulations(Monte Carlo,molecular dynamics and molecular statics).A significant number of stable vacant lattice sites with high migration energy barriers exists and is thought to cause the sluggish diffusion.We predict that the hexagonal close-packed(hcp)structure is more stable than the face-centered cubic(fcc)structure at 0 K,which we propose as the fundamental reason for the micro-twinning at cryogenic temperatures.The alloying effect on the critical resolved shear stress(CRSS)is well predicted by the atomistic simulation,used for a design of non-equiatomic fcc HEAs with improved strength,and is experimentally verified.This study demonstrates the applicability of the proposed atomistic approach combined with a thermodynamic calculation technique to a computational design of advanced HEAs. | Won-Mi Choi Yong Hee Jo Seok Su Sohn Sunghak Lee Byeong-Joo Lee | 2018 | npj Computational Materials2018，，1： | 11 |

| 11 | Association between Helicobacter pylori status and metachronous gastric cancer after endoscopic resection显示文摘AIM To investigate the effect of Helicobacter pylori(H. pylori) status test and H. pylori eradication on the occurrence of metachronous gastric cancer(MGC) after endoscopic submucosal dissection(ESD) of early gastric cancer(EGC) and risk factors of MGC. METHODS The authors retrospectively reviewed the medical records of 433 patients(441 lesions) who underwent ESD for EGC from January 2005 to January 2015 in Yeungnam University Hospital. Patients were categorized into two groups; the H. pylori tested group(n = 257) and the H. pylori non-tested group(n = 176) based on performance of H. pylori status test after ESD of EGC. The H. pylori tested group was further categorized into three subgroups based on H. pylori status; the H. pylori-eradicated subgroup(n = 120), the H. pylori-persistent subgroup(n = 42), and the H. pylori-negative subgroup(n = 95). Incidences of MGC and risk factors of MGC were identified.RESULTS Median follow-up duration after ESD was 30.00 mo(range, 6-107 mo). Total 15 patients developed MGC during follow-up. MGC developed in 11 patients of the H. pylori tested group(7 in the H. pylori-negative subgroup, 3 in the H. pylori-eradicated subgroup, and 1 in the H. pylori-persistent subgroup) and 4 patients of the H. pylori non-tested group(P > 0.05). The risk factors of MGC were endoscopic mucosal atrophy in the H. pylori tested group and intestinal metaplasia in all patients. CONCLUSION H. pylori eradication and H. pylori status test seems to have no preventive effect on the development of MGC after ESD for EGC. The risk factors of MGC development were endoscopic mucosal atrophy in the H. pylori tested group alone and intestinal metaplasia in all patients. | Sung Bum Kim Si Hyung Lee Seung Il Bae Yo Han Jeong Se Hoon Sohn Kyeong Ok Kim Byung Ik Jang Tae Nyeun Kim | 2016 | World Journal of Gastroenterology2016，22，44： | 8 |
| 12 | Hepatic artery pseudoaneurysm caused by acute idiopathic pancreatitis显示文摘Hepatic artery pseudoaneurysm(HAP) is a very rare disease but in cases of complication,there is a very high mortality.The most common cause of HAP is iatrogenic trauma such as liver biopsy,transhepatic biliary drainage,cholecystectomy and hepatectomy.HAP may also occur with complications such as infections or inflammation associated with septic emboli.HAP has been reported rarely in patients with acute pancreatitis.As far as we are aware,there is no report of a case caused by acute idiopathic pancreatitis,particularly.We report a case of HAP caused by acute idiopathic pancreatitis which developed in a 61-year-old woman.The woman initially presented with acute pancreatitis due to unknown cause.After conservative management,her symptoms seemed to have improved.But eight days after admission,abdominal pain abruptly became worse again.Abdominal computed tomography(CT) was rechecked and it detected a new HAP that was not seen in a previous abdominal CT.Endoscopic retrograde cholangiopancreatography(ERCP) was performed because of a suspicion of hemobilia as a cause of aggravated abdominal pain.ERCP confirmed hemobilia by observing fresh blood clots at the opening of the ampulla and several filling defects in the distal common bile duct on cholangiogram.Without any particular treatment such as embolization or surgical ligation,HAP thrombosed spontaneously.Three months after discharge,abdominal CT demonstrated that HAP in the left lateral segment had disappeared. | Yeon Hwa Yu Joo Hyun Sohn Tae Yeob Kim Jae Yoon Jeong Dong Soo Han Yong Cheol Jeon Min Young Kim | 2012 | World Journal of Gastroenterology2012，18，18： | 8 |
| 13 | Fuzzy entropy design for non convex fuzzy set and application to mutual information显示文摘Fuzzy entropy was designed for non convex fuzzy membership function using well known Hamming distance measure.The proposed fuzzy entropy had the same structure as that of convex fuzzy membership case.Design procedure of fuzzy entropy was proposed by considering fuzzy membership through distance measure,and the obtained results contained more flexibility than the general fuzzy membership function.Furthermore,characteristic analyses for non convex function were also illustrated.Analyses on the mutual information were carried out through the proposed fuzzy entropy and similarity measure,which was also dual structure of fuzzy entropy.By the illustrative example,mutual information was discussed. | LEE Sang-Hyuk LEE Sang-Min SOHN Gyo-Yong KIM Jaeh-Yung | 2011 | Journal of Central South University2011，18，1： | 7 |
| 14 | Pre-operative predictive factors for gallbladder cholesterol polyps using conventional diagnostic imaging显示文摘AIM:To determine the clinical data that might be useful for differentiating benign from malignant gallbladder (GB) polyps by comparing radiological methods,including abdominal ultrasonography (US) and computed tomography (CT) scanning,with postoperative pathology fi ndings. METHODS:Fifty-nine patients underwent laparoscopic cholecystectomy for a GB polyp of around 10 mm. They were divided into two groups,one with cholesterol polyps and the other with non-cholesterol polyps. Clinical features such as gender,age,symptoms,size and number of polyps,the presence of a GB stone,the radiologically measured maximum diameter of the polyp by US and CT scanning,and the measurements of diameter from postoperative pathology were recorded for comparative analysis. RESULTS:Fifteen of the 41 cases with cholesterol polyps (36.6%) were detected with US but not CT scanning,whereas all 18 non-cholesterol polyps were observed using both methods. In the cholesterol polyp group,the maximum measured diameter of the polyp was smaller by CT scan than by US.Consequently,the discrepancy between those two scanning measurements was greater than for the non-cholesterol polyp group. CONCLUSION:The clinical signs indicative of a cholesterol polyp include:(1) a polyp observed by US but not observable by CT scanning,(2) a smaller diameter on the CT scan compared to US,and (3) a discrepancy in its maximum diameter between US and CT measurements. In addition,US and the CT scan had low accuracy in predicting the polyp diameter compared to that determined by postoperative pathology. | Ji-Hoon Choi Jung-Won Yun Yong-Sung Kim Eun-A Lee Sang-Tae Hwang Yong-Kyun Cho Hong-Joo Kim Jung-Ho Park Dong-Il Park Chong-Il Sohn Woo-Kyu Jeon Byung-Ik Kim Hyoung-Ook Kim Jun-Ho Shin | 2008 | World Journal of Gastroenterology2008，14，44： | 7 |

| 19 | A New Infrared Atmospheric Sounding Interferometer Channel Selection and Assessment of Its Impact on Met Office NWP Forecasts显示文摘A new set of Infrared Atmospheric Sounding Interferometer(IASI) channels was re-selected from 314 EUMETSAT channels.In selecting channels,we calculated the impact of the individually added channel on the improvement in the analysis outputs from a one-dimensional variational analysis(1D-Var) for the Unified Model(UM) data assimilation system at the Met Office,using the channel score index(CSI) as a figure of merit.Then,200 channels were selected in order by counting each individual channel's CSI contribution.Compared with the operationally used 183 channels for the UM at the Met Office,the new set shares 149 channels,while the other 51 channels are new.Also examined is the selection from the entropy reduction method with the same 1D-Var approach.Results suggest that channel selection can be made in a more objective fashion using the proposed CSI method.This is because the most important channels can be selected across the whole IASI observation spectrum.In the experimental trial runs using the UM global assimilation system,the new channels had an overall neutral impact in terms of improvement in forecasts,as compared with results from the operational channels.However,upper-tropospheric moist biases shown in the control run with operational channels were significantly reduced in the experimental trial with the newly selected channels.The reduction of moist biases was mainly due to the additional water vapor channels,which are sensitive to the upper-tropospheric water vapor. | Young-Chan Noh Byung-Ju Sohn Yoonjae Kim Sangwon Joo William Bell Roger Saunders | 2017 | Advances in Atmospheric Sciences2017，34，11： | 6 |
| 20 | Role of two-dimensional shear wave elastography in chronic liver diseases: A narrative review显示文摘Liver biopsy is the gold standard for evaluating the degree of liver fibrosis in patients with chronic liver disease. However, due to the many limitations of liver biopsy, there has been much interest in the use of noninvasive techniques for this purpose. Among these techniques real-time two-dimensional shear wave elastography(2D-SWE) has the advantage of measuring tissue elasticity with the guidance of B-mode images. Recently, many studies have been conducted on the application of 2D-SWE in patients with various liver diseases, and their validity has been confirmed. Here, we briefly discuss the role of 2D-SWE in patients with chronic liver diseases, particularly aspects of the examination techniques and clinical applications. | Jae Yoon Jeong Young Seo Cho Joo Hyun Sohn | 2018 | World Journal of Gastroenterology2018，24，34： | 5 |
