1Treatment strategies using adefovir dipivoxil for individuals with lamivudine-resistant chronic hepatitis B显示文摘AIM:To investigate retrospectively the long-term efficacy of various treatment strategies using adefovir dipivoxil(adefovir) in patients with lamivudine-resistant chronic hepatitis B.METHODS:We included 154 consecutive patients in two treatment groups:the 'add-on' group(n = 79),in which adefovir was added to ongoing lamivudine treatment due to lamivudine resistance,and the 'switch/combination' group(n = 75),in which lamivudine was first switched to adefovir and then re-added later as needed.The 'switch/combination' group was then divided into two subgroups depending on whether participants followed(group A,n = 30) or violated(group B,n = 45) a proposed treatment strategy that determined whether to add lamivudine based on the serum hepatitis B virus(HBV) DNA levels(< 60 IU/mL or not) after 6 mo of treatment(roadmap concept).RESULTS:The cumulative probability of virologic response(HBV DNA < 60 IU/mL) was higher in group A than in the 'add-on' group and in group B(P < 0.001).In contrast,the cumulative probability of virologic breakthrough was lower in the 'add-on' group than in group B(P = 0.002).Furthermore,the risk of virologic breakthrough in the multivariate analysis was significantly lower in the 'add-on' group than in group A(hazard ratio = 0.096;95%CI,0.015-0.629;P = 0.015).CONCLUSION:The selective combination of adefovir with lamivudine based upon early treatment responses increased the odds of virologic breakthrough relative to the use of uniform combination therapy from the beginning of treatment.Tae Jung Yun Jin Yong Jung Chang Ha Kim Soon Ho Um Hyonggin An Yeon Seok Seo Jin Dong Kim Hyung Joon Yim Bora Keum Yong Sik Kim Yoon Tae Jeen Hong Sik Lee Hoon Jai Chun Chang Duck Kim Ho Sang Ryu 2012World Journal of Gastroenterology2012,18,47:19
2Endoscopic ultrasound-guided choledochoduodenostomies with fully covered self-expandable metallic stents显示文摘AIM:To investigate the long-term outcomes of endoscopic ultrasound-guided choledochoduodenostomy(EUS-CDS) with a fully covered self-expandable metallic stent(FCSEMS).METHODS:From April 2009 to August 2010,15 patients with distal malignant biliary obstructions who were candidates for alternative techniques for biliary decompression due to a failed endoscopic retrograde cholangiopancreatography(ERCP) were included.These 15 patients consisted of 8 men and 7 women and had a median age of 61 years(range:30-91 years).The underlying causes of the distal malignant biliary obstruction were pancreatic cancer(n = 9),ampulla of Vater cancer(n = 2),renal cell carcinoma(n = 1),advanced gastric cancer(n = 1),lymphoma(n = 1),and duodenal cancer(n = 1).RESULTS:The technical success rate of EUS-CDS with an FCSEMS was 86.7%(13/15),and functional success was achieved in 100%(13/13) of those cases.In two patients,the EUS-CDS failed because an FCSEMS with a delivery device could not be passed into the common bile duct.The mean duration of stent patency was 264 d.Early adverse events developed in three patients(3/13,23.1%),including self-limited pneumoperitoneum in two patients and cholangitis requiring stent reposition in one patient.During the follow-up period(median:186 d,range:52-388 d),distal stent migration occurred in four patients(4/13,30.8%).In 3 patients,the FCSEMS could be reinserted through the existing choledochoduodenal fistula tract.CONCLUSION:EUS-CDS with an FCSEMS is technically feasible and can lead to effective palliation of distal malignant biliary obstructions after failed ERCP.Tae Jun Song Yil Sik Hyun Sang Soo Lee Do Hyun Park Dong Wan Seo Sung Koo Lee Myung-Hwan Kim 2012World Journal of Gastroenterology2012,18,32:8
3A Computational Study of Thrust Vectoring Control Using Dual Throat Nozzle显示文摘Dual throat nozzle (DTN) is fast becoming a popular technique for thrust vectoring. The DTN is designed with two throats, an upstream minimum and a downstream minimum at the nozzle exit, with a cavity in between the upstream throat and exit. In the present study, a computational work has been carried out to analyze the performance of a dual throat nozzle at various mass flow rates of secondary flow and nozzle pressure ratios (NPR). Two-dimensional, steady, compressible Navier-Stokes equations were solved using a fully implicit finite volume scheme. The present computational results were validated with available experimental data. Based on the present results, the control effectiveness of thrust-vectoring is discussed in terms of the thrust coefficient and the coefficient of discharge.Choon Sik Shin Heuy Dong Kim Toshiaki Setoguchi Shigeru Matsuo 2010Journal of Thermal Science2010,19,6:6
4Significant risk and associated factors of active tuberculosis infection in Korean patients with inflammatory bowel disease using anti-TNF agents显示文摘AIM:To evaluate the incidence and risk factors of Korean tuberculosis(TB) infection in patients with inflammatory bowel disease(IBD) undergoing anti-TNF treatment.METHODS:The data of IBD patients treated with anti-TNFs in 13 tertiary referral hospitals located in the southeastern region of Korea were collected retrospectively.They failed to show response or were intolerant to conventional treatments,including steroids or immunomodulators.Screening measures for latent TB infection(LTBI)and the incidence and risk factors ofactive TB infection after treatment with anti-TNFs were identified.RESULTS:Overall,376 IBD patients treated with antiTNF agents were recruited(male 255,mean age of anti-TNF therapy 32.5±13.0 years);277 had Crohn’s disease,99 had ulcerative colitis,294 used infliximab,and 82 used adalimumab.Before anti-TNF treatment,screening tests for LTBI including an interferon gamma release assay or a tuberculin skin test were performed in 82.2%of patients.Thirty patients(8%)had LTBI.Sixteen cases of active TB infection including one TB-related mortality occurred during 801 personyears(PY)follow-up(1997.4 cases per 100000 PY)after anti-TNF treatment.LTBI(OR=5.76,95%CI:1.57-21.20,P=0.008)and WBC count<5000 mm3(OR=4.5,95%CI:1.51-13.44,P=0.007)during follow-up were identified as independently associated risk factors.CONCLUSION:Anti-TNFs significantly increase the risk of TB infection in Korean patients with IBD.The considerable burden of TB and marked immunosuppression might be attributed to this risk.Eun Soo Kim Geun Am Song Kwang Bum Cho Kyung Sik Park Kyeong Ok Kim Byung Ik Jang Eun Young Kim Seong Woo Jeon Hyun Seok Lee Chang Heon Yang Yong Kook Lee Dong Wook Lee Sung Kook Kim Tae Oh Kim Jonghun Lee Hyung Wook Kim Sam Ryong Jee Seun Ja Park Hyun Jin Kim 2015World Journal of Gastroenterology2015,21,11:5

6Computed tomography findings for predicting severe acute hepatitis with prolonged cholestasis显示文摘AIM: To evaluate the significance of computed tomography (CT) findings in relation to liver chemistry and the clinical course of acute hepatitis. METHODS: Four hundred and twelve patients with acute hepatitis who underwent enhanced CT scanning were enrolled retrospectively. Imaging findings were analyzed for the following variables: gallbladder wall thickness (GWT), arterial heterogeneity, periportal tracking, number and maximum size of lymph nodes, presence of ascites, and size of spleen. The serum levels of alanine aminotransferase, alkaline phosphatase, bilirubin, albumin, and prothrombin time were measured on the day of admission and CT scan, and laboratory data were evaluated every 2-4 d for all subjects during hospitalization. RESULTS: The mean age of patients was 34.4 years, and the most common cause of hepatitis was hepatitis A virus (77.4%). The mean GWT was 5.2 mm. The number of patients who had findings of arterial heterogeneity, periportal tracking, lymph node enlargement > 7 mm, and ascites was 294 (80.1%), 348 (84.7%), 346 (84.5%), and 56 (13.6%), respectively. On multivariate logistic regression, male gender [odds ratio (OR) = 2.569, 95%CI: 1.477-4.469, P = 0.001], toxic hepatitis (OR = 3.531, 95%CI: 1.444-8.635, P = 0.006), level of albumin (OR = 2.154, 95%CI: 1.279-3.629, P = 0.004), and GWT (OR = 1.061, 95%CI: 1.015-1.110, P = 0.009) were independent predictive factors for severe hepatitis. The level of bilirubin (OR = 1.628, 95%CI: 1.331-1.991, P < 0.001) and GWT (OR = 1.172, 95%CI: 1.024-1.342,P = 0.021) were independent factors for prolonged cholestasis in multivariate analysis. CONCLUSION: In patients with acute hepatitis, GWT on CT scan was an independent predictor of severe hepatitis and prolonged cholestasis.Sang Jung Park Jin Dong Kim Yeon Seok Seo Beom Jin Park Min Ju Kim Soon Ho Um Chang Ha Kim Hyung Joon Yim Soon Koo Baik Jin Yong Jung Bora Keum Yoon Tae Jeen Hong Sik Lee Hoon Jai Chun Chang Duck Kim Ho Sang Ryu 2013World Journal of Gastroenterology2013,19,16:4
7Intraductal papillary bile duct adenocarcinoma and gastrointestinal stromal tumor in a case of neurofibromatosis type 1显示文摘We report our experience with a synchronous case of gastrointestinal stromal tumor(GIST) and intraductal papillary neoplasm of the bile duct(IPNB) in anelderly woman with neurofibromatosis type 1(NF-1). A 72-year-old woman presented with a 2-mo history of right upper abdominal pain unrelated to diet and indigestion. Fourteen years earlier, she had been diagnosed with NF-1, which manifested as café au lait spots and multiple nodules on the skin. Computed tomography(CT) revealed a multilocular low-density mass with septation, and mural nodules in the right hepatic lobe, as well as a 1.7-cm-sized well-demarcated enhancing mass in the third portion of the duodenum. The patient subsequently underwent right hepatectomy and duodenal wedge resection. We present here the first report of a case involving a synchronous IPNB and GIST in a patient with NF-1. Our findings demonstrate the possibility of various tumors in NF-1 patients and the importance of diagnosis at an earlyJung Min Lee Jae Min Lee Jong Jin Hyun Hyuk Soon Choi Eun Sun Kim Bora Keum Yoon Tae Jeen Hoon Jai Chun Hong Sik Lee Chang Duck Kim Dong Sik Kim Joo Young Kim 2018World Journal of Gastroenterology2018,24,4:4

9Evaluation of SWAT sub-daily runoff estimation at small agricultural watershed in Korea显示文摘A study was undertaken for the prediction of runoff flow from 0.8 ha field-sized agricultural watershed in South Korea using Soil and Water Assessment Tool (SWAT) sub-daily. The SWAT model with sub-daily configuration predicted flow from the watershed within the range of acceptable accuracy. The SWAT sub-daily simulations were carried out for a total of 18 rainfall events, 9 each for calibration and validation. Overall trend and extent of matching simulated flow for the rainfall events in 2007-2008 with measured data during the calibration process were coefficient of determination (R2) value of 0.88 and Nash and Sutcliffe Efficiency (ENs) value of 0.88. For validation, R2 and ENs values were 0.9 and 0.84, respectively. Whereas R2 and ENs values for simulation results using daily rainfall data were 0.79 and -0.01, respectively, that were observed to be out of acceptable limits for the model simulation. The importance of higher time resolution (hourly) precipitation records for flow simulation were evaluated by comparing Ra and ENs with 15 min, 2 h, 6 h and 12 h precipitation data, which resulted in lower statistics with increases in time resolution of precipitation data. The SWAT sub-daily sensitivity analysis was performed with the consideration of hydraulic parameter and was found as in the rank order of CN2 (curve number), ESCO (soil evaporation compensation factor), GW_DELAY (ground water delay time), ALPHA BF (base flow alpha factor), GWQMN (a threshold-minimum depth of water in the shallow aquifer required for return flow to occur), REVAPMN (minimum depth of water in shallow aquifer for re-evaporation to occur), LAT TIME (lateral flow travel time) respectively. These sensit]-ve parameters were evaluated at 10% higher and lower values of the parameters, corresponding to 70.5% higher and 23.2% lower in simulated flow out from the SWAT model. From the results obtained in this study, hourly precipitation record for SWAT sub-daily with Green-Ampt infiltration method was proven to be efficient for runoff estimation at field sized watershed with higher accuracies that could be efficiently used to develop site- specific Best Management Practices (BMPs) considering rainfall intensity, rather than simply using daily rainfall data.Ganga Ram Maharjan Youn Shik Park Nam Won Kim Dong Seok Shin Jae Wan Choi Geun Woo Hyun Ji-Hong Jeon Yong Sik Ok Kyoung Jae Lim 2013Frontiers of Environmental Science & Engineering2013,7,1:2
