| 1 | 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 |
| 2 | Prevalence of clonorchiasis in patients with gastrointestinal disease: A Korean nationwide multicenter survey显示文摘AIM: To investigate prevalence of Clonorchis sinensis in patients with gastrointestinal symptoms, and the relation of the infection to hepatobiliary diseases in 26 hospitals in Korea.METHODS: Consecutive patients who had been admitted to the Division of Gastroenterology with gastrointestinal symptoms were enrolled from March to April 2005. Of those who had been diagnosed with clonorchiasis, epidemiology and correlation between infection and hepatobiliary diseases were surveyed by questionnaire.RESULTS: Of 3080 patients with gastrointestinal diseases, 396 (12.9%) had clonorchiasis and 1140 patients (37.2%) had a history of eating raw freshwater fish. Of those with a history of raw freshwater fish ingestion, 238 (20.9%) patients had clonorchiasis. Cholangiocarcinoma was more prevalent in C. sinensis-infected patients than non-infected patients [34/396 (8.6%) vs 145/2684 (5.4%), P = 0.015]. Cholangiocarcinoma and clonorchiasis showed statistically significant positive cross-relation (P = 0.008). Choledocholithiasis, cholecystolithiasis, cholangitis, hepatocellular carcinoma, and biliary pancreatitis did not correlate with clonorchiasis.CONCLUSION: Infection rate of clonorchiasis was still high in patients with gastrointestinal diseases in Korea, and has not decreased very much during the last two decades. Cholangiocarcinoma was related to clonorchiasis, which suggested an etiological role for the parasite. | Ho Gak Kim Jimin Han Myung-Hwan Kim Kyu Hyun Cho Im Hee Shin Gwang Ha Kim Jae Seon Kim Jin Bong Kim Tae Nyeun Kim Tae Hyeon Kim Tae Hyo Kim Jae Woo Kim Ji Kon Ryu Young-Soo Moon Jong Ho Moon Sung Jae Park Chan Guk Park Sung-Jo Bang Chang Heon Yang Kyo-Sang Yoo Byung Moo Yoo Kyu Taek Lee Dong Ki Lee Byung Seok Lee Sang Soo Lee Seung Ok Lee Woo Jin Lee Chang Min Cho Young-Eun Joo Gab Jin Cheon Young Woo Choi Jae Bok Chung Yong Bum Yoon | 2009 | World Journal of Gastroenterology2009，15，1： | 15 |
| 3 | Low skeletal muscle mass is associated with non-alcoholic fatty liver disease in Korean adults: the Fifth Korea National Health and Nutrition Examination Survey显示文摘BACKGROUND: Sarcopenia and non-alcoholic fatty liver disease(NAFLD) share similar pathophysiological mechanisms, and the relationship between sarcopenia and NAFLD has been recently investigated. The study investigated whether low skeletal muscle mass is differentially associated with NAFLD by gender in Korean adults.METHODS: We conducted a cross-sectional analysis of the data from the Fifth Korea National Health and Nutrition Examination Survey. The skeletal muscle index(SMI) was obtained by the appendicular skeletal muscle mass divided by the weight. NAFLD was defined as a fatty liver index(FLI) ≥60 in the absence of other chronic liver disease.RESULTS: Among the included subjects, 18.3%(SE: 1.4%) in men and 7.0%(SE: 0.7%) in women were classified as having FLI-defined NAFLD. Most of the risk factors for FLI-defined NAFLD showed a significant negative correlation with the SMI in both genders. Multiple logistic regression analysis showed that low SMI was associated with FLI-defined NAFLD, independent of other metabolic and lifestyle parameters in both genders [males: odds ratio(OR)=1.35; 95% confidence interval(CI): 1.17-1.54; females: OR=1.36; 95% CI: 1.18-1.55]. The magnitude of the association between FLI-defined NAFLD and low SMI was higher in middle aged to elderly males(OR=1.50; 95% CI: 1.22-1.84) than in males less than 45 years of age(OR=1.25; 95% CI: 1.02-1.52) and in premenopausal females(OR=1.50; 95% CI: 1.12-2.03) than in postmenopausal females(OR=1.36; 95% CI: 1.20-1.54).CONCLUSIONS: Low SMI is associated with the risk of FLIdefined NAFLD independent of other well-known metabolic risk factors in both genders. This association may differ according to age group or menopausal status. Further studies are warranted to confirm this relationship. | hee yeon kim chang wook kim chung-hwa park jong young choi kyungdo han anwar t merchant yong-moon park | 2016 | Hepatobiliary & Pancreatic Diseases International2016，15，1： | 7 |
| 4 | Assessment of scoring systems for acute-on-chronic liver failure at predicting short-term mortality in patients with alcoholic hepatitis显示文摘AIM To assess the performance of proposed scores specific for acute-on-chronic liver failure in predicting shortterm mortality among patients with alcoholic hepatitis.METHODS We retrospectively collected data from 264 patients with clinically diagnosed alcoholic hepatitis from January to December 2013 at 21 academic hospitals in Korea. The performance for predicting short-term mortality was calculated for Chronic Liver FailureSequential Organ Failure Assessment(CLIF-SOFA), CLIF Consortium Organ Failure score(CLIF-C OFs), Maddrey'sdiscriminant function(DF), age, bilirubin, international normalized ratio and creatinine score(ABIC), Glasgow Alcoholic Hepatitis Score(GAHS), model for end-stage liver disease(MELD), and MELD-Na.RESULTS Of 264 patients, 32(12%) patients died within 28 d. The area under receiver operating characteristic curve of CLIF-SOFA, CLIF-C OFs, DF, ABIC, GAHS, MELD, and MELD-Na was 0.86(0.81-0.90), 0.89(0.84-0.92), 0.79(0.74-0.84), 0.78(0.72-0.83), 0.81(0.76-0.86), 0.83(0.78-0.88), and 0.83(0.78-0.88), respectively, for 28-d mortality. The performance of CLIF-SOFA had no statistically significant differences for 28-d mortality. The performance of CLIF-C OFs was superior to that of DF, ABIC, and GAHS, while comparable to that of MELD and MELD-Na in predicting 28-d mortality. A CLIF-SOFA score of 8 had 78.1% sensitivity and 79.7% specificity, and CLIF-C OFs of 10 had 68.8% sensitivity and 91.4% specificity for predicting 28-d mortality.CONCLUSION CLIF-SOFA and CLIF-C OF scores performed well, with comparable predictive ability for short-term mortality compared to the commonly used scoring systems in patients with alcoholic hepatitis. | Hee Yeon Kim Chang Wook Kim Tae Yeob Kim Do Seon Song Dong Hyun Sinn Eileen L Yoon Young Kul Jung Ki Tae Suk Sang Soo Lee Chang Hyeong Lee Tae Hun Kim Jeong Han Kim Hyung Joon Yim Sung Eun Kim Soon Koo Baik Byung Seok Lee Jae Young Jang Young Seok Kim Sang Gyune Kim Jin Mo Yang Joo Hyun Sohn Heon Ju Lee Seung Ha Park Eun Hee Choi Dong Joon Kim Korean Acute-on-Chronic Liver Failure Study Group | 2016 | World Journal of Gastroenterology2016，22，41： | 5 |
| 5 | Development of a low-cost GPS/INS integrated system for tractor automatic navigation显示文摘The use of low-cost single GPS receivers and inertial sensors for auto-guidance applications has been limited by their reduced accuracy and signal drift over time compared to real-time kinematic(RTK)differential GPS units and fiber-optic gyroscope(FOG)sensors.In this study,a prototype low-cost GPS/INS integrated system consisting of a triangle-shaped array of three Garmin 19x GPS receivers and an Xsens inertial measurement unit(IMU)to improve the accuracy of position and heading angle measured with a single GPS receiver was developed.A triangular algorithm that uses data collected from the three single GPSs mounted on the angular points of a triangular frame was designed.A sensor fusion algorithm based on the Kalman filter combining the GPS and IMU data was developed by integrating position data and heading angles of a triangular array of GPS receivers.The optimized values of two noise covariance matrixes(Q and R)for the Kalman filtering were determined using the Central Composite Design(CCD)method.As compared to the use of a single Garmin GPS receiver,use of the developed GPS/INS system showed improved accuracy performance in terms of both position and heading angle,with reductions in root mean square errors(RMSEs)from 2.7 m to 0.64 m for position and from 8.9ºto 2.1ºfor heading angle.The accuracy improvements show new potential for agricultural auto-guidance applications. | Xiongzhe Han Hak-Jin Kim Chan Woo Jeon Hee Chang Moon Jung Hun Kim | 2017 | International Journal of Agricultural and Biological Engineering2017，10，2： | 3 |
| 6 | 健康男性的胰岛素抵抗指数、肥胖、血清PSA水平间的关系显示文摘本研究旨在确定血清PSA水平低于4ngmL^-1的健康男性的胰岛素抵抗指数、肥胖和血清前列腺特异性抗原(PSA)水平之间的关系。调查对象为韩国水力原子力株式会社的11827名健康男性职员,在2003年1月到2008年12月间接受了体检,体检项目包括空腹血糖水平、空腹胰岛素水平和血清PSA水平。用稳态模式评估法(HOMA;[空腹血糖水平×空腹胰岛素水平]/22.5)和定量胰岛素敏感性检验指数(QUICKI;1/[10g(空腹胰岛素水平)+log(空腹血糖水平)])测定胰岛素抵抗指数。协方差分析(ANOVA)和Duncan’s多重比较试验显示,随着用HOMA和OuICKI测定的胰岛素抵抗指数四分位的上升,年龄标化体重指数(BMI)也显著增加(P〈0.001)。多变量线性回归分析表明,相对于血清PSA水平,年龄、BMI、以及用HOMA或QUICKI测得的胰岛素抵抗指数都是显著的独立变量(P〈0.001)。本研究说明胰岛素抵抗指数和BMI都是血清PSA水平的独立变量,在健康男性体内,两者都与血清PSA水平呈负相关,两者之间呈正相关。 | June Hyun Han Yong Taec Lee Kyung Won Kwak Seung Hyun Ahn In Ho Chang Soon Chul Myung Seung Young Oh Yong-Seong Lee Wonyong Kim Young-Woo Jin Tae-In Choi Sook Hee Sung | 2010 | Asian Journal of Andrology2010，12，3： | 2 |
| 7 | Diagnosis of gastric epithelial neoplasia:Dilemma for Korean pathologists显示文摘The histopathological diagnosis of gastric mucosal biopsy and endoscopic mucosal resection/endoscopic submucosal dissection specimens is important,but the diagnostic criteria,terminology,and grading system are not the same in the East and West.A structurally invasive focus is necessary to diagnose carcinoma for most Western pathologists,but Japanese pathologists make a diagnosis of cancer based on severe dysplastic cytologic atypia irrespective of the presence of invasion.Although the Vienna classification was introduced to reduce diagnostic discrepancies,it has been difficult to adopt due to different concepts for gastric epithelial neoplastic lesions.Korean pathologists experience much difficulty making a diagnosis because we are influenced by Japanese pathologists as well as Western medicine.Japan is geographically close to Korea,and academic exchanges are active.Additionally,Korean doctors are familiar with Western style medical terminology.As a result,the terminology,definitions,and diagnostic criteria for gastric intraepithelial neoplasia are very heterogeneous in Korea.To solve this problem,the Gastrointestinal Pathology Study Group of the Korean Society of Pathologists has made an effort and has suggested guidelines for differential diagnosis:(1) a diagnosis of carcinoma is based on invasion;(2) the most important characteristic of low grade dysplasia is the architectural pattern such as regular distribution of crypts without severe branching,budding,or marked glandular crowding;(3) if nuclear pseudostratification occupies more than the basal half of the cryptal cells in three or more adjacent crypts,the lesion is considered high grade dysplasia;(4) if severe cytologic atypia is present,careful inspection for invasive foci is necessary,because the risk for invasion is very high;and(5) other structural or nuclear atypia should be evaluated to make a final decision such as cribriform pattern,papillae,ridges,vesicular nuclei,high nuclear/cytoplasmic ratio,loss of nuclear polarity,thick and irregular nuclear membrane,and nucleoli. | Joon Mee Kim Mee-Yon Cho Jin Hee Sohn Dae Young Kang Cheol Keun Park Woo Ho Kim So-Young Jin Kyoung Mee Kim Hee Kyung Chang Eunsil Yu Eun Sun Jung Mee Soo Chang Jong Eun Joo Mee Joo Youn Wha Kim Do Youn Park Yun Kyung Kang Sun Hoo Park Hye Seung Han Young Bae Kim Ho Sung Park Yang Seok Chae Kye Won Kwon Hee Jin Chang The Gastrointestinal Pathology Study Group of Korean Society of Pathologists | 2011 | World Journal of Gastroenterology2011，17，21： | 2 |
