| 1 | Role of ascites adenosine deaminase in differentiating between tuberculous peritonitis and peritoneal carcinomatosis显示文摘AIM: To investigate the usefulness of tumor markers and adenosine deaminase in differentiating between tuberculous peritonitis (TBP) and peritoneal carcinoma- tosis (PC). METHODS: A retrospective analysis of data was performed on consecutive patients who underwent perito-neoscopic and abdominal computed tomography (CT) evaluations. Among 75 patients at the Seoul National University Hospital from January 2000 to June 2010 who underwent both tests, 27 patients (36.0%) and 25 patients (33.3%) were diagnosed with TBP and PC, respectively. Diagnosis was confirmed by peritoneoscopic biopsy. RESULTS: Serum c-reactive protein (7.88 ± 6.62 mg/ dL vs 3.12 ± 2.69 mg/dL, P = 0.01), ascites adenosine deaminase (66.76 ± 32.09 IU/L vs 13.89 ± 8.95 IU/L, P < 0.01), ascites lymphocyte proportion (67.77 ± 23.41% vs 48.36 ± 18.78%, P < 0.01), and serumascites albumin gradient (0.72 ± 0.49 g/dL vs 1.05 ± 0.50 g/dL, P = 0.03) were significantly different between the two groups. Among tumor markers, serum and ascites carcinoembryonic antigen, serum carbohydrate antigen 19-9 showed significant difference between two groups. Abdominal CT examinations showed that smooth involvement of the parietal peritoneum was more common in the TBP group (77.8% vs 40.7%) whereas nodular involvement was more common in the PC group (14.8% vs 40.7%, P = 0.04). From receiver operating characteristic (ROC) curves ascites adenosines deaminase (ADA) showed better discriminative capability than tumor markers. An ADA cut-off level of 21 IU/L was found to yield the best results of differential diagnosis; sensitivity, specificity, positive predictive value, and negative predictive value were 92.0%, 85.0%, 88.5% and 89.5%, respectively. CONCLUSION: Besides clinical and radiologic findings, ascitic fluid ADA measurement is helpful in the differential diagnosis of TBP and PC. | Seung Joo Kang Ji Won Kim Jee Hyun Baek Se Hyung Kim Byeong Gwan Kim Kook Lae Lee Ji Bong Jeong Yong Jin Jung Joo Sung Kim Hyun Chae Jung In Sung Song | 2012 | World Journal of Gastroenterology2012，18，22： | 15 |
| 2 | Relationship between diversion colitis and quality of life in rectal cancer显示文摘AIM:To investigated the incidence of diversion colitis(DC) and impact of DC symptoms on quality of life(QoL) after ileostomy reversal in rectal cancer.METHODS:We performed a prospective study with 30 patients who underwent low anterior resection and the creation of a temporary ileostomy for the rectal cancer between January 2008 and July 2009 at the Department of Surgery,Korea University Anam Hospital.The participants totally underwent two rounds of the examinations.At first examination,endoscopies,tissue biopsies,and questionnaire survey about the symptom were performed 3-4 mo after the ileostomy creations.At second examination,endoscopies,tissue biopsies,and questionnaire survey about the symptom and QoL were performed 5-6 mo after the ileostomy reversals.Clinicopathological data were based on the histopathological reports and clinical records of the patients.RESULTS:At the first examination,all of the patients presented with inflammation,which was mild in 15(50%) patients,moderate in 11(36.7%) and severe in 4(13.3%) by endoscopy and mild in 14(46.7%) and moderate in 16(53.3%) by histology.At the second examination,only 11(36.7%) and 17(56.7%) patients had mild inflammation by endoscopy and histology,respectively.There was no significant difference in DC grade between the endoscopic and the histological findings at first or second examination.The symptoms detected on the first and second questionnaires were mucous discharge in 12(40%) and 5(17%) patients,bloody discharge in 5(17%) and 3(10%) patients,abdominal pain in 4(13%) and 2(7%) patients and tenesmus in 9(30%) and 5(17%) patients,respectively.We found no correlation between the endoscopic or histological findings and the symptoms such as mucous discharge,bleeding,abdominal pain and tenesmus in both time points.Diarrhea was detected in 9 patients at the second examination;this number correlated with the severity of DC(0%,0%,66.7%,33.3% vs 0%,71.4%,23.8%,4.8%,P = 0.001) and the symptom-related QoL(r =-0.791,P < 0.001).CONCLUSION:The severity of DC is related to diarrhea after an ileostomy reversal and may adversely affect QoL. | Dong Nyoung Son Dong Jin Choi Si Uk Woo Jin Kim Bo Ra Keom Chul Hwan Kim Se Jin Baek Seon Hahn Kim | 2013 | World Journal of Gastroenterology2013，19，4： | 14 |

| 4 | Removal of primary iron rich phase from aluminum-silicon melt by centrifugal separation显示文摘Recycling is a major consideration in continued aluminum use due to the enormous demand for high quality products. Some impurity elements gradually accumulate through the repetitive reuse of aluminum alloy scrap. Of them, the iron content should be suppressed under the allowed limit. In the present research, a novel separation method was introduced to remove primary iron-rich intermetallic compounds by centrifugation during solidification of Al-Si-Fe alloys. This method does not use the density difference between two phases as in other centrifugal methods, but uses the order of solidification in Al-Si-Fe alloys, because iron promotes the formation of intermetallic compounds with other alloying elements as a primary phase. Two Al-Si-Fe alloys which have different iron contents were chosen as the starting materials. The iron-rich phase could be efficiently removed by centrifuging under a centrifugal force of 40 g. Coarse intermetallic compounds were found in the sample inside the crucible, while rather fine intermetallic compounds were found in the sample outside the crucible. Primary intermetallic compounds were linked to each other via aluminum-rich matrix, and formed like a network. The highest iron removal fraction is 67% and the lowest one is 7% for Al-12Si-1.7Fe alloy. And they are 82% and 18% for Al-12Si-3.4Fe alloy, respectively. | Seong Woo Kim Un Ho Im Hyeong Cheol Cha Se Hyeong Kim Ji Eun Jang Ki Young Kim | 2013 | China Foundry2013，10，2： | 8 |
| 5 | 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 |

| 8 | Effects of Cr interlayer on mechanical and tribological properties of Cr-Al-Si-N nanocomposite coating显示文摘Cr-Al-Si-N coatings were deposited on SUS 304 substrate by a hybrid coating system. A Cr interlayer was introduced between Cr-Al-Si-N coating and SUS 304 substrate to improve the coating adherence. The effects of Cr interlayer on the microhardness, adhesion, and tribological behavior of Cr-Al-Si-N coatings were systematically investigated. The results indicate that the microhardness of the Cr-Al-Si-N coatings gradually deceases with increasing thickness of Cr interlayers. The adhesion between Cr-Al-Si-N and SUS 304 substrate is improved by addition of the Cr interlayers. A peak critical load of ~50 N is observed for the coating containing Cr interlayer of 60 nm as compared ~ 20 N for the coating without Cr interlayer. The thicker Cr interlayers result in reduced critical load values. Moreover, the wear resistance of the Cr-Al-Si-N coatings is greatly enhanced by introducing the Cr interlayer with thickness of 60 nm in spite of the decreased microhardness. The friction coefficient of the coating system is also moderately reduced. | Young Su HONG Se Hun KWON Tiegang WANG Doo-In KIM Jihwan CHOI Kwang Ho KIM | 2011 | Transactions of Nonferrous Metals Society of China2011，21，A01： | 6 |
| 9 | Absolute monocyte and lymphocyte count prognostic score for patients with gastric cancer显示文摘AIM:To measure the prognostic significance of absolute monocyte count/absolute lymphocyte count prognostic score(AMLPS) in patients with gastric cancer.METHODS:We retrospectively examined the combination of absolute monocyte count(AMC) and absolute lymphocyte count(ALC) as prognostic variables in a cohort of 299 gastric cancer patients who underwent surgical resection between 2006 and 2013 and were followed at a single institution.Both AMC and ALC were dichotomized into two groups using cut-off points determined by receiving operator characteristic curve analysis.An AMLPS was generated,which stratified patients into three risk groups:low risk(both low AMC and high ALC),intermediate risk(either high AMC or low ALC),and high risk(both high AMC and low ALC).The primary objective of the study was to validate the impact of AMLPS on both disease-free survival(DFS) and overall survival(OS),and the second objective was to assess the AMLPS as an independent prognostic factor for survival in comparison with known prognostic factors.RESULTS:Using data from the entire cohort,the most discriminative cut-off values of AMC and ALC selected on the receiver operating characteristic curve were 672.4/μL and 1734/μL for DFS and OS.AMLPS risk groups included 158(52.8%) patients in the lowrisk,128(42.8%) in the intermediate-risk,and 13(4.3%) in the high-risk group.With a median followup of 37.2 mo(range:1.7-91.4 mo),five-year DFS rates in the low-,intermediate-,and high-risk groups were 83.4%,78.7%,and 19.8%,respectively.And fiveyear OS rates in the low-,intermediate-,and high-risk groups were 89.3%,81.1%,and 14.4%,respectively.On multivariate analysis performed with patient- and tumor-related factors,we identified AMLPS,age,and pathologic tumor-node-metastasis stage as the most valuable prognostic factors impacting DFS and OS.CONCLUSION:AMLPS identified patients with a poor DFS and OS,and it was independent of age,pathologic stage,and various inflammatory markers. | Wan Kyu Eo Da Wun Jeong Hye Jung Chang Kyu Yeoun Won Sung Il Choi Se Hyun Kim Sung Wook Chun Young Lim Oh Tae Hwa Lee Young Ok Kim Ki Hyung Kim Yong Il Ji Ari Kim Heung Yeol Kim | 2015 | World Journal of Gastroenterology2015，21，9： | 6 |

| 12 | Clinical outcome of Fitz-Hugh-Curtis syndrome mimicking acute biliary disease显示文摘AIM: To analyze the clinical characteristics of patients diagnosed with Fitz-Hugh-Curtis syndrome.METHODS: The clinical courses of patients that visited St. Mary's Hospital with abdominal pain from January 2005 to December 2006 and were diagnosed with Fitz-Hugh-Curtis syndrome were examined.RESULTS: Fitz-Hugh-Curtis syndrome was identified in 22 female patients of childbearing age; their mean age was 31.0 ± 8.1 years. Fourteen of these cases presented with pain in the upper right abdomen alone or together with pain in the lower abdomen, and six patients presented with pain only in the lower abdomen. The first impression at the time of visit was acute cholecystitis or cholangitis in 10 patients and acute appendicitis or pelvic inflammatory disease in eight patients. Twenty-one patients were diagnosed by abdominal computer tomograghy (CT), and the results of abdominal sonography were normal for 10 of these patients. Chlamydia trichomatis was isolated from 18 patients. Two patients underwent laparoscopic adhesiotomy and 20 patients were completely cured by antibiotic treatment.CONCLUSION: For women of childbearing age with acute pain in the upper right abdomen alone or together with pain in the lower abdomen, Fitz-Hugh-Curtis syndrome should be considered during differential diagnosis. Moreover, in cases suspected to be Fitz-Hugh-Curtis syndrome, abdominal CT, rather than abdominal sonography, assists in the diagnosis. | Seong Yong Woo Jin Il Kim Dae Young Cheung Se Hyun Cho Soo-Heon Park Joon-Yeol Han Jae Kwang Kim | 2008 | World Journal of Gastroenterology2008，14，45： | 5 |
| 13 | Early bile duct cancer显示文摘Bile duct cancers are frequently diagnosed as advanced diseases. Over half of patients with advanced bile duct cancer present with unresectable malignancies and their prognosis has been very poor even after curative resections. Although there has been a need to diagnose bile duct cancer at its early stage, it has been a diffi cult goal to achieve due to our lack of knowledge regarding this disease entity. Early bile duct cancer may be defi ned as a carcinoma whose invasion is confined within the fibromuscular layer of the extrahepatic bile duct or intrahepatic large bile duct without distant metastasis irrespective of lymph node involvement. Approximately 3%-10% of resected bile duct cancers have been reported to be early cancers in the literature. The clinicopathological features of patients with early bile duct cancer differ from those of patients with advanced bile duct cancer, with more frequent asymptomatic presentation, characteristic histopathological findings, and excellent prognosis. This manuscript is organized to emphasize the need for convening an international consensus to develop the concept of early bile duct cancer. | Jae Myung Cha Myung-Hwan Kim Se Jin Jang | 2007 | World Journal of Gastroenterology2007，13，25： | 4 |
| 14 | Cryptogenic multifocal ulcerous stenosing enteritis: Radiologic features and clinical behavior显示文摘AIM To investigate the characteristic radiologic findings of cryptogenic multifocal ulcerous stenosing enteritis(CMUSE) which can be differentiated from other similar bowel disease and to assess their clinical behavior.METHODS Twenty pathologically and clinically confirmed CMUSE patients(males:females = 8:12; mean age: 40.4 years) between March 2002 and August 2015 from seven academic centers in South Korea were retrospectively reviewed. We evaluated small bowel series(SBS; n = 25), computed tomography(CT) enterography(n = 21), magnetic resonance(MR) enterography(n = 2), and abdominopelvic CT(n = 18) images, focusing on enteric and perienteric manifestations. Any change in radiologic features during followup period was recorded. We evaluated clinical data including presenting symptoms, laboratory finding and presence of relapse from electronic medical records. Histopathologic findings were also evaluated. RESULTS The main symptoms were abdominal pain(n = 12) and anemia(n = 10). All patients showed small bowel strictures(n = 52, mean: 2.6 per patient) on initial CT/MR, located in the ileum(n = 47) or jejunum(n = 5). Strictures showed short-length(mean: 10.44 mm) and circumferential bowel wall thickening(mean: 5.56 mm) with layered enhancement(n = 48) that were also noted on initial SBS(n = 36) with shallow ulcers(n = 10). Some ulcerative lesions or wall thickening progressed into strictures on follow-up SBS/CT, and some strictures revealed recurrent ulceration on followup SBS. There were no penetrating disease features like fistula or abscess and no gastrointestinal tract involvement except the small bowel. Nine patients experienced disease recurrence(median relapse-free period: 32 mo) even post-operatively. Histopathologic features of surgically resected specimens were characterized as multiple superficial ulcerations confined to mucosa or submucosa and multiple strictures.CONCLUSION Under characteristic radiologic findings with multiple short-segmental strictures and/or shallow ulcers of the small intestine, CMUSE should be considered when assessing patients with recurrent abdominal pain and anemia. | Jiyoung Hwang Jin Sil Kim Ah Young Kim Joon Seok Lim Se Hyung Kim Min Ju Kim Mi Sung Kim Kyoung Doo Song Ji Young Woo | 2017 | World Journal of Gastroenterology2017，23，25： | 4 |

| 17 | Chemotherapy beyond second-line in advanced gastric cancer显示文摘Patients with advanced gastric cancer(AGC) can be treated with multiple lines of chemotherapy. Although several randomized trials have demonstrated the benefit of second-line chemotherapy compared with best supportive care, there is no evidence that further lines of chemotherapy will result in substantial prolongation of survival. Despite this, the practice of offering chemotherapy beyond second-line agents to AGC patients is not uncommon if their performance status is well-preserved and they are willing to receive subsequent active treatments. The choice of chemotherapeutic agents depends on the patient's prior regimens. However, there are important controversial issues in the salvage setting of AGC, including a subset of patients who may benefit from chemotherapy, that still remain unanswered. This report reviews the available evidence regarding the impact of third- and subsequent lines of chemotherapy on survival and quality of life in patients with AGC. | Sung Min Kim Se Hoon Park | 2015 | World Journal of Gastroenterology2015，21，29： | 4 |
| 18 | Ezetimibe improves hepatic steatosis in relation to autophagy in obese and diabetic rats显示文摘AIM: To investigate whether ezetimibe ameliorates hepatic steatosis and induces autophagy in a rat model of obesity and type 2 diabetes. METHODS: Male age-matched lean control LETO and obese and diabetic OLETF rats were administered either PBS or ezetimibe(10 mg/kg per day) via stomach gavage for 20 wk. Changes in weight gain and energy intake were regularly monitored. Blood and liver tissue were harvested after overnight fasting at the end of study. Histological assessment was performed in liver tissue. The concentrations of glucose, insulin, triglycerides(TG), free fatty acids(FFA), and total cholesterol(TC) in blood and TG, FFA, and TG in livertissue were measured. m RNA and protein abundance involved in autophagy was analyzed in the liver. To investigate the effect of ezetimibe on autophagy and reduction in hepatic fat accumulation, human Huh7 hepatocytes were incubated with ezetimibe(10 μmol/L) together with or without palmitic acid(PA, 0.5 mmol/L, 24 h). Transmission electron microscopy(TEM) was employed to demonstrate effect of ezetimibe on autophagy formation. Autophagic flux was measured with bafilomycin A1, an inhibitor of autophagy and following immunoblotting for autophagy-related protein expression.RESULTS: In the OLETF rats that received ezetimibe(10 mg/kg per day), liver weight were significantly decreased by 20% compared to OLETF control rats without changes in food intake and body weight(P < 0.05). Lipid parameters including TG, FFA, and TC in liver tissue of ezetimibe-administrated OLETF rats were dramatically decreased at least by 30% compared to OLETF controls(P < 0.01). The serum glucose, insulin, HOMA-IR, and lipid profiles were also improved by ezetimibe(P < 0.05). In addition, autophagy-related m RNA expression including ATG5, ATG6, and ATG7 and the protein level of microtubule-associated protein light chain 3(LC3) were significantly increased in the liver in rats that received ezetimibe(P < 0.05). Likewise, for hepatocytes cultured in vitro, ezetimibe treatment significantly decreased PA-induced fat accumulation and increased PA-reduced m RNA and protein expression involved in autophagy(P < 0.05). Ezetimibe-increased autophagosomes was observed in TEM analysis. Immunoblotting analysis of autophagy formation with an inhibitor of autophagy demonstrated that ezetimibe-increased autophagy resulted from increased autophagic flux. CONCLUSION: The present study demonstrates that ezetimibe-mediated improvement in hepatic steatosis might involve the induction of autophagy. | Eugene Chang Lisa Kim Se Eun Park Eun-Jung Rhee Won-Young Lee Ki-Won Oh Sung-Woo Park Cheol-Young Park | 2015 | World Journal of Gastroenterology2015，21，25： | 3 |
| 19 | Risk factors for tuberculosis after gastrectomy in gastric cancer显示文摘AIM: To examine incidence of tuberculosis(TB) in gastrectomy patients and investigate the risk factors for developing TB after gastrectomy in patients with gastric cancer.METHODS: A retrospective cohort study of gastrectomy patients with gastric cancer was performed at a university-affiliated hospital in Seoul, South Korea between January 2007 and December 2009. We reviewed patient medical records and collected data associated with the risk of TB, surgery, and gastric cancer. Standardized incidence ratios(SIRs) of TB were calculated to compare the incidence of TB in gastrectomy patients with that in the general Korean population, and risk factors for TB after gastrectomies were analyzed.RESULTS: Among the 1776 gastrectomy patients, 0.9%(16/1776) developed post-gastrectomy TB, with an incidence of 223.7 cases per 100000 patients per year. The overall incidence of TB in gastrectomy patients, adjusted by sex and age, was significantly higher thanthat in the general population(SIR = 2.22, 95%CI: 1.27-3.60). Previous TB infection [odds ratio(OR) = 7.1, P < 0.001], lower body mass index(BMI)(kg/m2; OR = 1.21, P = 0.043) and gastrectomy extent(total gastrectomy vs subtotal gastrectomy)(OR = 3.48, P = 0.017) were significant risk factors for TB after gastrectomy in a multivariate analysis.CONCLUSION: TB incidence after gastrectomy is higher than that in the general population. Previous TB infection, lower BMI, and total gastrectomy are risk factors for TB after gastrectomy in patients with gastric cancer. | Won Jai Jung Young Mok Park Joo Han Song Kyung Soo Chung Song Yee Kim Eun Young Kim Ji Ye Jung Moo Suk Park Young Sam Kim Se Kyu Kim Joon Chang Sung Hoon Noh Ji Yeong An Young Ae Kang | 2016 | World Journal of Gastroenterology2016，22，8： | 3 |
| 20 | Bispectral index monitoring as an adjunct to nurse-administered combined sedation during endoscopic retrograde cholangiopancreatography显示文摘AIM:To determine whether bispectral index (BIS) monitoring is useful for propofol administration for deep sedation during endoscopic retrograde cholangiopancreatography (ERCP). METHODS:Fifty-nine consecutive patients with a variety of reasons for ERCP who underwent the procedure at least twice between 1 July 2010 and 30 November 2010. This was a randomized cross-over study, in which each patient underwent ERCP twice, once with BIS monitoring and once with control monitoring. Whether BIS monitoring was done during the first or second ERCP procedure was random. Patients were intermittently administered a mixed regimen including midazolam, pethidine, and propofol by trained nurses. The nurse used a routine practice to monitor sedation using the Modified Observer's Assessment of Alertness/Sedation (MOAA/S) scale or the BIS monitoring. The total amount of midazolam and propofol used and serious side effects were compared between the BIS and control groups. RESULTS:The mean total propofol dose administered was 53.1 ± 32.2 mg in the BIS group and 54.9 ± 30.8 mg in the control group (P = 0.673). The individual propofol dose received per minute during the ERCP procedure was 2.90 ± 1.83 mg/min in the BIS group and 3.44 ± 2.04 mg in the control group (P = 0.103). The median value of the MOAA/S score during the maintenance phase of sedation was comparable for the two groups. The mean BIS values throughout the procedure (from insertion to removal of the endoscope) were 76.5 ± 8.7 for all 59 patients in using the BIS monitor. No significant differences in the frequency of < 80% oxygen saturation, hypotension (< 80 mmHg), or bradycardia (< 50 beats/min) were observed between the two study groups. Four cases of poor cooperation occurred, in which the procedure should be stopped to add the propofol dose. After adding the propofol, the procedure could be conducted successfully (one case in the BIS group, three cases in the control group). The endoscopist rated patient sedation as excellent for all patients in both groups. All patients in both groups rated their level of satisfaction as high (no discomfort). During the post-procedural follow-up in the recovery area, no cases of clinically significant hypoxic episodes were recorded in either group. No other postoperative side effects related to sedation were observed in either group. CONCLUSION:BIS monitoring trend to slighlty reduce the mean propofol dose. Nurse-administered propofol sedation under the supervision of a gastroenterologist may be considered an alternative under anesthesiologist. | Se Young Jang Hyun Gu Park Min Kyu Jung Chang Min Cho Soo Young Park Seong Woo Jeon Won Young Tak Young Oh Kweon Sung Kook Kim Young Hoon Jeon | 2012 | World Journal of Gastroenterology2012，18，43： | 3 |
