| 1 | Management of entecavir-resistant chronic hepatitis B with adefovir-based combination therapies显示文摘AIM: To evaluate the long-term efficacy adefovir(ADV)-based combination therapies in entecavir(ETV)-resistant chronic hepatitis B(CHB) patients. METHODS: F i fty CHB pat ient s wi t h genotypic resistance to ETV at 13 medical centers in South Korea were included for the analysis. All the patients received rescue therapy with the combination of ADV plus ETV(ADV/ETV,n = 23) or ADV plus lamivudine(LMV)(ADV/LMV,n = 27) for more than 12 mo. Patients were monitored at least every 3-4 mo during ADV-based combination therapy by clinical examination as well as biochemical and virological assessments. Hepatitis B virus(HBV) DNA levels were measured by realtime PCR and logarithmically transformed for analysis. Cumulative rates of virologic response(VR; HBV DNA < 20 IU/m L) were calculated using the Kaplan-Meier method,and the difference was determined by a logrank test. Multivariate logistic regression and Cox proportional hazards models were used to identify independent risk factors significantly associated with short-term and long-term VR,respectively.RESULTS: Baseline median HBV DNA levels were 5.53(2.81-7.63) log10 IU/m L. The most commonly observed ETV genotypic mutation sites were rt184 and rt202. Patients were treated for a median of 27(12-45) mo. Overall,cumulative VR rates at 6,12,24,and 36 mo were 26%,36%,45%,and 68%,respectively. Patients treated with the ADV/ETV combination showed higher cumulative VR rates(35%,43%,65%,and 76%,respectively) than those with the ADV/LAM combination(18%,30%,30%,and 62%,respectively; P = 0.048). In the multivariate analysis,low baseline HBV DNA levels(< 5.2 log10 IU/m L) and initial virologic response at 3 mo(IVR-3; HBV DNA < 3.3 log10 IU/m L after 3 mo) were independent predictive factors for VR. Patients with favorable predictors achieved cumulative VR rates up to 90% at 36 mo. During the same period,the cumulative incidence of virologic breakthrough was as low as 6% in patients with the both favorable predictors.CONCLUSION: If tenofovir is not available,ADV/ETV combination could be considered in ETV-resistant patients with low HBV DNA titers,and may becontinued if IVR-3 is achieved. | Hyoung Su Kim Hyung Joon Yim Myoung Kuk Jang Ji Won Park Sang Jun Suh Yeon Seok Seo Ji Hoon Kim Bo Hyun Kim Sang Jong Park Sae Hwan Lee Sang Gyune Kim Young Seok Kim Jung Il Lee Jin-Woo Lee In Hee Kim Tae Yeob Kim Jin-Wook Kim Sook-Hyang Jeong Young Kul Jung Hana Park Seong Gyu Hwang | 2015 | World Journal of Gastroenterology2015，21，38： | 13 |
| 2 | Iodized oil uptake assessment with cone-beam CT in chemoembolization of small hepatocellular carcinomas显示文摘AIM:To evaluate the utility of assessing iodized oil uptake with cone-beam computed tomography(CT)in transarterial chemoembolization(TACE)for small he-patocellular carcinoma(HCC).METHODS:Cone-beam CT provided by a biplane flat-panel detector angiography suite was performed on eighteen patients(sixteen men and two women;41-76 years;mean age,58.9 years)directly after TACE for small HCC(26 nodules under 30 mm;mean diam-eter,11.9 mm;range,5-28 mm).The pre-procedural locations of the tumors were evaluated using tripha-sic multi-detector row helical computed tomography(MDCT).The tumor locations on MDCT and the iodized oil uptake by the tumors were analyzed on cone-beam CT and on spot image directly after the procedures.RESULTS:All lesions on preprocedural MDCT were de-tected using iodized oil uptake in the lesions on cone-beam CT(sensitivity 100%,26/26).Spot image depictediodized oil uptake in 22 of the lesions(sensitivity 85%).The degree of iodized oil uptake was overestimated(9%,2/22)or underestimated(14%,3/22)on spot image in f ive nodules compared with that of cone-beam CT.CONCLUSION:Cone-beam CT is a useful and conve-nient tool for assessing the iodized oil uptake of small hepatic tumors(< 3 cm)directly after TACE. | Ung Bae Jeon Jun Woo Lee Ki Seok Choo Chang Won Kim Suk Kim Tae Hong Lee Yeon Joo Jeong Dae Hwan Kang | 2009 | World Journal of Gastroenterology2009，15，46： | 8 |
| 3 | 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 |
| 4 | Anxiety and depression propensities in patients with acute toxic liver injury显示文摘AIM:To investigate anxiety and depression propensities in patients with toxic liver injury.METHODS:The subjects were divided into three groups:a healthy control group(Group 1,n=125),an acute non-toxic liver injury group(Group 2,n=124),and a group with acute toxic liver injury group caused by noncommercial herbal preparations(Group 3,n=126).These three groups were compared and evaluated through questionnaire surveys and using the Hospital Anxiety-Depression Scale(HADS),Beck Anxiety Inventory(BAI),Beck Depression Inventory(BDI),and the hypochondriasis scale.RESULTS:The HADS anxiety subscale was 4.9±2.7,5.0±3.0 and 5.6±3.4,in Groups 1,2,and 3,respectively.The HADS depression subscale in Group 3 showed the most significant score(5.2±3.2,6.4±3.4 and 7.2±3.4in Groups 1,2,and 3,respectively)(P<0.01 vs Group 1,P<0.05 vs Group 2).The BAI and BDI in Group 3showed the most significant score(7.0±6.3 and 6.9±6.9,9.5±8.6 and 8.8±7.3,10.7±7.2 and 11.6±8.5in Groups 1,2,and 3,respectively)(BAI:P<0.01 vs Group 1,P<0.05 vs Group 2)(BDI:P<0.01 vs Group1 and 2).Group 3 showed a significantly higher hypochondriasis score(8.2±6.0,11.6±7.5 and 13.1±6.5in Groups 1,2,and 3,respectively)(P<0.01 vs Group 1,P<0.05 vs Group 2).CONCLUSION:Psychological factors that present vulnerability to the temptation to use alternative medicines,such as herbs and plant preparations,are important for understanding toxic liver injury. | Jeong Ill Suh Jeong Kyu Sakong Kwan Lee Yong Kook Lee Jeong Bae Park Dong Joon Kim Yeon Seok SeoDepartment of Internal Medicine Korea University Anam Hospital Korea University College of Medicine Seoul 136-705 South Korea Jae Dong Lee Soon Young Ko Byung Seok Lee Seok Hyun Kim Byung Seok Kim Young Seok Kim Heon Ju Lee In Hee Kim Joo Hyun Sohn Tae Yeob Kim Byung Min Ahn | 2013 | World Journal of Gastroenterology2013，19，47： | 5 |
| 5 | Is there correlation between pancreatic enzyme and radiological severity in acute pancreatitis?显示文摘AIM: To investigate the correlation between the changes of pancreatic enzyme, the biochemical markers and the clinical results according to the Balthazar computer tomography (CT) grade. METHODS: Between July 2004 and July 2005, we reviewed the charts of 119 patients who were admitted to our hospital with acute pancreatitis. RESULTS: Eighty-three patients (69.7%) were male, and the mean age of the patients was 57 ± 15.7 years. The biliary pancreatitis patients had an older mean age. Forty-nine patients (41.1%) had biliary pancreatitis and forty-six (38.6%) had alcoholic pancreatitis. Group 3 patients had a longer duration of pain (2.51 ± 1.16 vs 3.17 ± 1.30 vs 6.56 ± 6.13, P < 0.001), a longer period of fasting (7.49 ± 4.65 vs 10.65 ± 5.54 vs 21.88 ± 13.81, P < 0.001) and a longer hospital stay (9.17 ± 5.34 vs 14.63 ± 8.65 vs 24.47 ± 15.52, P < 0.001) than the other groups. On the univariate analysis, the factors that affected the radiological grade were the leukocyte count at admission (P = 0.048), the hemoglobin (P = 0.016) and total bilirubin concentrations (P = 0.023), serum lipase (P = 0.009), the APACH Ⅱ scores at admission (P = 0.017), the APACH Ⅱ scores after 24 h (P = 0.031), the C-reactive protein (CRP) titer (P = 0.0001) and the follow up CRP titer (P = 0.003). But the CRP level (P = 0.001) and follow up CRP titer (P = 0.004) were only correlated with the radiological grade on multivariate analysis. According to the ROC curve, when we set the CRP cut off value at 83 mg/L, the likelihoodratio for a positive test was 3.84 and the likelihood ratio for a negative test was 0.26 in group 3. CONCLUSION: In conclusion, our study suggests that the CRP with the radiological severity may be used to estimate the severity of acute pancreatitis. | Yeon Soo Kim Byung Seok Lee Seok Hyun Kim Jae Kyu Seong Hyun Yong Jeong Heon Young Lee | 2008 | World Journal of Gastroenterology2008，14，15： | 5 |

| 11 | Multidimensional Hybrid Architecture Encapsulating Cobalt Oxide Nanoparticles into Carbon Nanotube Branched Nitrogen-Doped Reduced Graphene Oxide Networks for Lithium–Sulfur Batteries显示文摘Lithium–sulfur batteries(LSBs)are regarded as promising candidates for the next-generation energy storage devices owing to their high-theoretical capacity(1675 mAh g^(−1))and affordable cost.However,several limitations of LSBs such as the lithium polysulfide shuttle,large volume expansion,and low electrical conductivity of sulfur need to be resolved for practical applications.To address these limitations,herein,a multidimensional architectured hybrid(Co@CNT/nG),where Co_(3)O_(4) nanoparticles are encapsulated into threedimensional(3D)porous N-doped reduced graphene oxide interconnected with carbon nanotube(CNT)branches,is synthesized through a simple pyrolysis method.The synergistic effect achieved through the homogeneously distributed and encapsulated Co_(3)O_(4) nanoparticles,the interconnected CNT branches,and the 3D hierarchical porous structure and N-doping of Co@CNT/nG significantly suppresses the shuttle effect of lithium polysulfides and enhances the conversion redox kinetics for the improved sulfur utilization.We validate this effect through various measurements including symmetric cells,Li_(2)S nucleation,shuttle currents,Tafel slopes,diffusion coefficients,and post-mortem analyses.Importantly,Co@CNT/nG-70S-based LSB cells achieve a high-specific capacity of 1193.1 mAh g^(−1) at 0.1 C and a low capacity decay rate of 0.030%per cycle for 700 cycles at 5 C,delivering a high areal capacity of 5.62 mAh cm^(−2) even with a loading of 6.5 mg cm^(−2). | Jeong Seok Yeon Young Hun Ko Tae Ho Park Hyunyoung Park Jongsoon Kim Ho Seok Park | 2022 | Energy & Environmental Materials2022，5，2： | 1 |

| 14 | Electrochemical and structural evolution of structured V_(2)O_(5) microspheres during Li-ion intercalation显示文摘With the development of stable alkali metal anodes,V_(2)O_(5) is gaining traction as a cathode material due to its high theoretical capacity and the ability to intercalate Li,Na and K ions.Herein,we report a method for synthesizing structured orthorhombic V_(2)O_(5) microspheres and investigate Li intercalation/deintercalation into this material.For industry adoption,the electrochemical behavior of V_(2)O_(5) as well as structural and phase transformation attributing to Li intercalation reaction must be further investigated.Our synthesized V_(2)O_(5) microspheres consisted of small primary particles that were strongly joined together and exhibited good cycle stability and rate capability,triggered by reversible volume change and rapid Li ion diffusion.In addition,the reversibility of phase transformation(a,e,d,c and xLixV_(2)O_(5))and valence state evolution(5+,4+,and 3.5+)during intercalation/de-intercalation were studied via in-situ X-ray powder diffraction and X-ray absorption near edge structure analyses. | Sul Ki Park Puritut Nakhanivej Jeong Seok Yeon Kang Ho Shin Wesley M.Dose Michael De Voider Jin Bae Lee Hae Jin Kim Ho Seok Park | 2021 | Journal of Energy Chemistry2021，30，4： | 0 |
| 15 | 2D spinel ZnCo_(2)O_(4) microsheet-coated functional separator for promoted redox kinetics and inhibited polysulfide dissolution显示文摘Lithium-sulfur(Li-S)batteries are receiving increasing attention as one of the potential next-generation batteries,owing to their high energy densities and low cost.However,practical Li-S batteries with high energy densities are extremely hindered by the sulfur loss,low Coulombic efficiency,and short cycling life originating from the polysulfide(LiPS)shuttle.In this study,two-dimensional(2D)ZnCo_(2)O_(4) microsheets fabricated by a facile hydrothermal process are employed to modify the separator,for improving the electrochemical performances of Li-S cells.The resulting 2D Zn Co_(2)O_(4)-coated separator features a coating thickness of approximately 10 lm,high ionic conductivity of 1.8 m S/cm,and low mass loading of 0.2 mg/cm^(2).This 2D ZnCo_(2)O_(4)-coated separator effectively inhibits Li PS shuttle by a strong chemical interaction with Li PS as well as promotes the redox kinetics by Zn CO2O4-coated layers,as determined by X-ray photoelectron spectroscopy analysis,self-discharge,time-dependent permeation test,Li symmetric cell test,and Li2S nucleation analyses.Consequently,the Li-S batteries based on the 2D Zn Co_(2)O_(4)-coated separator exhibit a high initial discharge capacity of 1292.2 m Ah/g at 0.1 C.Moreover,they exhibit excellent long cycle stability at 1 and 2 C with capacity retention of 84%and 86%even after800 cycles,corresponding to a capacity fading rate of 0.020%and 0.016%per cycle,respectively.Effectively,these Li-S cells with a high sulfur loading at 5.3 mg/cm^(2) and low electrolyte concentration of 9 l L/mg deliver a high discharge capacity of 4.99 m Ah/cm^(2) after 200 cycles at 0.1 C. | Jeong Seok Yeon Tae Ho Park Young Hun Ko Periyasamy Sivakumar Jun Su Kim Youngkywon Kim Ho Seok Park | 2021 | Journal of Energy Chemistry2021，30，4： | 0 |
