| 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 | Characterization of smooth muscle, enteric nerve, interstitial cells of Cajal, and fibroblast-like cells in the gastric musculature of patients with diabetes mellitus显示文摘AIM To investigate histologic abnormalities in the gastric smooth muscle of patients with diabetes mellitus(DM).METHODS Full-thickness gastric specimens were obtained from patients undergoing surgery for gastric cancer. H&E stain and Masson's Trichrome stain were performed to assess the degree of fibrosis. Immunohistochemical staining using various antibodies was also performed [antibodies against protein gene product 9.5(PGP9.5), neuronal nitric oxide synthase(n NOS), vasoactive intestinal peptide(VIP), neurokinin-1(NK1) receptor, c-Kit, and platelet-derived growth factor receptor-alpha,(PDGFRα)]. Immunofluorescent staining and evaluation with confocal microscopy were also conducted.RESULTS Twenty-six controls and 35 diabetic patients(21 shortduration patients and 14 long-duration patients) were included. There were no significant differences in basic demographics between the two groups except in mean body mass index(BMI)(higher in the DM group). Proportions of moderate-to-severe intercellular fibrosis in the muscle layer were significantly higher in the DM group than in the control group(P < 0.01). On immunohistochemical staining, c-Kit- and PDGFRα-positive immunoreactivity were significantly decreased in the DM group compared with the control group(P < 0.05). There were no statistically significant differences in PGP9.5, n NOS, VIP, and neurokinin 1 expression. On immunofluorescent staining, cellularity of interstitial cells of Cajal(ICC) was observed to decrease with increasing duration of DM.CONCLUSION Our study suggests that increased intercellular fibrosis, loss of ICC, and loss of fibroblast-like cells are found in the smooth muscle of DM patients. These abnormalities may contribute to changes in gastric motor activity in patients with DM. | Kyung Sik Park Kwang Bum Cho Il Seon Hwang Jae Hyung Park Byung Ik Jang Kyeong Ok Kim Sung Woo Jeon Eun Soo Kim Chang Sik Park Joong Goo Kwon | 2016 | World Journal of Gastroenterology2016，22，46： | 11 |
| 3 | Diffusion-weighted imaging of biliopancreatic disorders:Correlation with conventional magnetic resonance imaging显示文摘Diffusion-weighted magnetic resonance imaging(DWI)is a well established method for the evaluation of intracranial diseases,such as acute stroke.DWI for extracranial application is more difficult due to physiological motion artifacts and the heterogeneous composition of the organs.However,thanks to the newer technical development of DWI,DWI has become increasingly used over the past few years in extracranial organs including the abdomen and pelvis.Most previous studies of DWI have been limited to the evaluation of diffuse parenchymal abnormalities and focal lesions in abdominal organs,whereas there are few studies about DWI for the evaluation of the biliopancreatic tract.Although further studies are needed to determine its performance in evaluating bile duct,gallbladder and pancreas diseases,DWI has potential in the assessment of the functional information on the biliopancreatic tract concerning the status of tissue cellularity,because increased cellularity is associated with impeded diffusion,as indicated by a reduction in the apparent diffusion coefficient.The detection of malignant lesions and their differentiation from benign tumor-like lesions in the biliopancreatic tract could be improved using DWI in conjunction with findings obtained with conventional magnetic resonance cholagiopancreatography.Additionally,DWI can be useful for the assessment of the biliopancreatic tract in patients with renal impairment because contrast-enhanced computed tomography or magnetic resonance scans should be avoided in these patients. | Nam Kyung Lee Suk Kim Gwang Ha Kim Dong Uk Kim Hyung Il Seo Tae Un Kim Dae Hwan Kang Ho Jin Jang | 2012 | World Journal of Gastroenterology2012，18，31： | 8 |
| 4 | 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 |
| 5 | Correlations between endoscopic and clinical disease activity indices in intestinal Behcet's disease显示文摘AIM:To develop a novel endoscopic severity model of intestinal Behcet's disease(BD) and to evaluate its feasibility by comparing it with the actual disease activity index for intestinal Behcet's disease(DAIBD).METHODS:We reviewed the medical records of 167 intestinal BD patients between March 1986 and April 2011.We also investigated the endoscopic parameters including ulcer locations,distribution,number,depth,shape,size and margin to identify independent factors associated with DAIBD.An endoscopic severity model was developed using significant colonoscopic variables identified by multivariate regression analysis and its correlation with the DAIBD was evaluated.To determine factors related to the discrepancy between endoscopic severity and clinical activity,clinical characteristics and laboratory markers of the patients were analyzed.RESULTS:A multivariate regression analysis revealed that the number of intestinal ulcers(≥ 2,P = 0.031) and volcanoshaped ulcers(P = 0.001) were predictive factors for the DAIBD.An endoscopic severity model(Y) was developed based on selected endoscopic variables as follows:Y = 47.44 + 9.04 × non-Ileocecal area + 11.85 ×≥ 2 of intestinal ulcers + 5.03 × shallow ulcers + 12.76 × deep ulcers + 4.47 × geographicshaped ulcers + 26.93 × volcano-shaped ulcers + 8.65 ×≥ 20 mm of intestinal ulcers.However,endoscopic parameters used in the multivariate analysis explained only 18.9% of the DAIBD variance.Patients with severe DAIBD scores but with moderately predicted disease activity by the endoscopic severity model had more symptoms of irritable bowel syndrome(21.4% vs 4.9%,P = 0.026) and a lower rate of corticosteroid use(50.0% vs 75.6%,P = 0.016) than those with severe DAIBD scores and accurately predicted disease by the model.CONCLUSION:Our study showed that the number of intestinal ulcers and volcano-shaped ulcers were predictive factors for severe DAIBD scores.However,the correlation between endoscopic severity and DAIBD(r = 0.434) was weak. | Hyun Jung Lee Youn Nam Kim Hui Won Jang Han Ho Jeon Eun Suk Jung Soo Jung Park Sung Pil Hong Tae Il Kim Won Ho Kim Chung Mo Nam Jae Hee Cheon | 2012 | World Journal of Gastroenterology2012，18，40： | 5 |
| 6 | Trends in the eradication rates of Helicobacter pylori infection for eleven years显示文摘AIM:To evaluate the trends in the eradication rate of Helicobacter pylori(H.pylori) over the past 11 years in a single center.METHODS:This retrospective study covered the period from January 2000 to December 2010.We evaluated 5746 patients diagnosed with gastric ulcers(GU),duodenal ulcers(DU),GU + DU,or nonpeptic ulcers associated with an H.pylori infection.We treated them annually with the 2 wk standard first-line triple regimen,proton pump inhibitor(PPI) + amoxicilin + clarithromycin(PAC;PPI,clarithromycin 500 mg,and amoxicillin 1 g,all twice a day).The follow-up test was performed at least 4 wk after the completion of the 2 wk standard H.pylori eradication using the PAC regimen.We also assessed the eradication rates of 1 wk second-line therapy with a quadruple standard regimen(PPI b.i.d.,tripotassium dicitrate bismuthate 300 mg q.i.d.,metronidazole 500 mg t.i.d.,and tetracycline 500 mg q.i.d.) after the failure of the first-line therapy.Statistical analysis was performed with 95%CI for the differences in the annual eradication rates.RESULTS:A total of 5746 patients [2333 males(58.8%),1636 females(41.2%);mean age of males vs females 51.31 ± 13.1 years vs 52.76 ± 13.6 years,P < 0.05,total mean age 51.9 ± 13.3 years(mean ± SD)] were investigated.Among these patients,1674 patients were excluded:35 patients refused treatment;18 patients ceased H.pylori eradication due to side effects;1211 patients had inappropriate indications for H.pylori eradication,having undergone stomach cancer operation or chemotherapy;and 410 patients did not undergo the follow-up.We also excluded 103 patients who wanted to stop eradication treatment after only 1 wk due to poor compliance or the side effects mentioned above.Finally,we evaluated the annual eradication success rates in a total of 3969 patients who received 2 wk first-line PAC therapy.The endoscopic and clinical findings in patients who received the 2 wk PAC were as follows:gastric ulcer in 855(21.5%);duodenal ulcer in 878(22.1%);gastric and duodenal ulcer in 124(3.1%),erosive,atrophic gastritis and functional dyspepsia in 2055(51.8%);and other findings(e.g.,MALToma,patients who wanted to receive the therapy even though they had no abnormal endoscopic finding) in 57(0.5%).The overall eradication rate of the 2 wk standard firstline triple regimen was 86.5%.The annual eradication rates from 2000 to 2010 were 86.7%,85.4%,86.5%,83.3%,89.9%,90.5%,88.4%,84.5%,89.1%,85.8%,and 88.3%,sequentially(P = 0.06).No definite evidence of a significant change in the eradication rate was seen during the past eleven years.The eradication rates of second-line therapy were 88.9%,82.4%,85%,83.9%,77.3%,85.7%,84.4%,87.3%,83.3%,88.9%,and 84%(P = 0.77).The overall eradication rate of 1 wk quadruple second-line therapy was 84.7%.There was no significant difference in the eradication rate according to the H.pylori associated diseases.CONCLUSION:This study showed that there was no trend change in the H.pylori eradication rate over the most recent 11 years in our institution. | Jai Hoon Yoon Gwang Ho Baik Kyoung Min Sohn Dae Yong Kim Yeon Soo Kim Ki Tae Suk Jin Bong Kim Dong Joon Kim Jin Bae Kim Woon Geon Shin Hak Yang Kim Il Hyun Baik Hyun Joo Jang | 2012 | World Journal of Gastroenterology2012，18，45： | 3 |
| 7 | Endoscopic submucosal dissection for early gastric cancer:Quo vadis?显示文摘The diagnosis of early gastric cancer(EGC) is of great interest because its endoscopic and surgical treatment presents the best chance for a cure.With technical development,endoscopic submucosal dissection(ESD) has been widely performed for the curative treatment of EGC in Korea.Multinational studies of ESD for EGC will be the next missions that overcome these limitations and global guidelines will be processed for ESD for EGC. | Won Young Cho Joo Young Cho Il Kwun Chung Jin Il Kim Jin Seok Jang Jae Hak Kim | 2011 | World Journal of Gastroenterology2011，17，21： | 3 |
| 8 | Humulus japonicus extract alleviates oxidative stress and apoptosis in 6-hydroxydopamine-induced PC12 cells显示文摘Objective:To explore the possible neuroprotective activities of Humulus japonicus extract against Parkinson's disease(PD)in a cellular model.Methods:PD was modeled in PC12 cells using 6-hydroxydopamine(6-OHDA).The cell activity,intracellular levels of reactive oxygen species(ROS),anti-oxidative and anti-apoptotic effects,and other related indicators and related signaling pathways were evaluated to elucidate the neuroprotective effects of Humulus japonicus extract.Results:Humulus japonicus extract exhibited anti-oxidative and anti-apoptotic effects in 6-OHDA-stimulated PC12 cells.It also reduced oxidative stress-induced ROS accumulation;upregulated antioxidant enzymes,such as glutathione,catalase,heme oxidase-1,and 8-oxguanine glycosylase 1;promoted cell survival by decreasing BAX and increasing Bcl-2 and sirtuin 1 expression via the MAPK and/or Nrf2 signaling pathways.Conclusions:Humulus japonicus extract has antioxidative and anti-apoptotic effects and could be developed as a promising candidate for preventing and treating oxidative stress-related neurodegenerative diseases. | Feng Wang Byoung Ok Cho Jae Young Shin Suping Hao Seon Il Jang | 2022 | Asian Pacific Journal of Tropical Biomedicine2022，12，5： | 2 |
