| 1 | Treatment for gastric ‘indefinite for neoplasm/dysplasia' lesions based on predictive factors显示文摘BACKGROUND Gastric ‘indefinite for neoplasm/dysplasia'(IFND) is a borderline lesion that is difficult to diagnose as either regenerative or neoplastic. There is a need for guidance in the identification of a subset of patients, who have an IFND lesion with a higher risk of malignant potential, to enable risk stratification and optimal management.AIM To determine the clinical and pathologic factors for the accurate diagnosis of gastric IFND lesions.METHODS In total, 461 gastric lesions diagnosed via biopsy as IFND lesions were retrospectively evaluated. Endoscopic resection(n = 134), surgery(n = 22), and follow-up endoscopic biopsy(n = 305) were performed to confirm the diagnosis.The time interval from initial biopsy to cancer diagnosis was measured, and diagnostic delays were categorized as > 2 wk, > 2 mo, > 6 mo, and > 1 year. The IFND lesions presenting as regenerating atypia(60%) or atypical epithelia(40%)at initial biopsy were adenocarcinomas in 22.6%, adenomas in 8.9%, and gastritis in 68.5% of the cases.RESULTS Four clinical factors [age ≥ 60 years(2.445, 95%CI: 1.305-4.580, P = 0.005),endoscopic size ≥ 10 mm(3.519, 95%CI: 1.891-6.548, P < 0.001), single lesion(5.702, 95%CI: 2.212-14.696, P < 0.001), and spontaneous bleeding(4.056, 95%CI:1.792-9.180, P = 0.001)], and two pathologic factors [atypical epithelium(25.575,95%CI: 11.537-56.695, P < 0.001], and repeated IFND diagnosis [6.022, 95%CI:1.822-19.909, P = 0.003)] were independent risk factors for gastric cancer. With two or more clinical factors, the sensitivity and specificity for carcinoma were91.3% and 54.9%, respectively. Ten undifferentiated carcinomas were initially diagnosed as IFND. In the subgroup analysis, fold change(5.594, 95%CI: 1.458-21.462, P = 0.012) predicted undifferentiated or invasive carcinoma in the submucosal layers or deeper. Diagnostic delays shorter than 1 year were not associated with worse prognoses. Extremely well-differentiated adenocarcinomas accounted for half of the repeated IFND cases and resulted in low diagnostic accuracy even on retrospective blinded review.CONCLUSION More than two clinical and pathologic factors each had significant cut-off values for gastric carcinoma diagnosis; in such cases, endoscopic resection should be considered. | Mi Jung Kwon Ho Suk Kang Hyeon Tae Kim Jin Woo Choo Bo Hyun Lee Sung Eun Hong Kun Ha Park Dong Min Jung Hyun Lim Jae Seung Soh Sung Hoon Moon Jong Hyeok Kim Hye-Rim Park Soo Kee Min Jin won Seo Ji-Young Choe | 2019 | World Journal of Gastroenterology2019，25，4： | 4 |
| 2 | Magnifying endoscopy of gastric epithelial dysplasia based on the morphologic characteristics显示文摘AIM:To investigate the difference in magnifying endoscopic findings of gastric epithelial dysplasias(GEDs)according to the morphologic characteristics.METHODS:This study included 46 GED lesions in 45patients who underwent magnifying endoscopy using narrow band imaging(ME-NBI)before endoscopic resection.During ME-NBI,the microvascular and microsurface(MS)patterns and the presence of light blue crest(LBC)and white opaque substance were investigated.GEDs were categorized as adenomatous,foveolar,and hybrid types,and their mucin phenotype was evaluated.RESULTS:Of the 46 lesions,27(59%)were categorized as adenomatous,15(32%)as hybrid,and the remaining 4(9%)as foveolar.All adenomatous GEDs showed the round pit and/or tubular MS patterns,all foveolar GEDs showed the papillary pattern,and hybrid GEDs showed mixed patterns(P<0.001).LBC was more frequently observed in adenomatous GEDs than in hybrid or foveolar GEDs(52%,33%,0%,respectively),although this difference was not significant(P=0.127).The papillary MS pattern was associated with MUC5AC and MUC6 expression,and the round pit and/or tubular MS patterns were associated with CD10expression.CONCLUSION:The MS pattern in ME-NBI findings is useful for predicting the morphologic category and mucin phenotype of GEDs,and ME-NBI findings may guide decisions regarding GED treatment. | Hwa Mi Kang Gwang Ha Kim Do Youn Park Hong Ryeol Cheong Dong Hoon Baek Bong Eun Lee Geun Am Song | 2014 | World Journal of Gastroenterology2014，20，42： | 4 |
| 3 | Improvement of diabetes and hypertension after gastrectomy: A nationwide cohort study显示文摘AIM: To evaluate the effect of gastrectomy on diabetes mellitus(DM) and hypertension(HTN) in non-obese gastric cancer patients. METHODS: A total of 100000 patients, diagnosed with either type 2 DM or HTN, were randomly selected from the 2004 Korean National Health Insurance System claims. Among them, 360 diabetes and 351 hypertensive patients with gastric cancer who had been regularly treated without chemotherapy from January 2005 to December 2010 were selected. They were divided into three groups according to their treatment methods: total gastrectomy(TG), subtotal gastrectomy(STG) and endoscopic resection(ER). RESULTS: The drug discontinuation rate of antidiabetic and anti-hypertensive agents after gastric cancer treatment was 9.7% and 11.1% respectively. DM appeared to be improved more frequently(22.8%) and earlier(mean ± SE 28.6 ± 1.8 mo) in TG group than in the two other groups [improved in 9.5% of ER group(37.4 ± 1.1 mo) and 6.4% of STG group(47.0 ± 0.8 mo)]. The proportion of patients treated with multiple drugs decreased more notably in TG group compared to others(P = 0.001 in DM, and P = 0.035 in HTN). In TG group, adjusted hazard ratio for theimprovement of DM was 2.87(95%CI: 1.15-7.17) in a multi-variate analysis and better control of DM was observed with survival analysis(P < 0.001).CONCLUSION: TG was found to decrease the need for anti-diabetic medications which can be reflective of improved glycemic control, to a greater extent than either ER or STG in non-obese diabetic patients. | Eun Kyung Lee So Young Kim You Jin Lee Mi Hyang Kwak Hak Jin Kim Il Ju Choi Soo-Jeong Cho Young Woo Kim Jong Yeul Lee Chan Gyoo Kim Hong Man Yoon Bang Wool Eom Sun-Young Kong Min Kyong Yoo Jong Hyock Park Keun Won Ryu | 2015 | World Journal of Gastroenterology2015，21，4： | 3 |

| 5 | Pravastatin activates the expression of farnesoid X receptor and liver X receptor alpha in Hep3B cells显示文摘BACKGROUND: Statins are suggested to preserve gallbladder function by suppressing pro-inflammatory cytokines and preventing cholesterol accumulation in gallbladder epithelial cells. They also affect cross-talk among the nuclear hormone receptors that regulate cholesterol-bile acid metabolism in the nuclei of hepatocytes. However, there is controversy over whether or how statins change the expression of peroxisome proliferator-activated receptor(PPAR)α, PPARγ, liver X receptor α(LXRα), farnesoid X receptor(FXR), ABCG5, ABCG8, and 7α-hydroxylase(CYP7A1) which are directly involved in the cholesterol saturation index in bile. METHODS: Human Hep3B cells were cultured on dishes. MTT assays were performed to determine the appropriate concentrations of reagents to be used. The protein expression of PPARα and PPARγ was measured by Western blotting analysis, and the mRNA expression of LXRα, FXR, ABCG5, ABCG8 and CYP7A1 was estimated by RT-PCR. RESULTS: In cultured Hep3B cells, pravastatin activated PPARα and PPARγ protein expression, induced stronger expression of PPARγ than that of PPARα, increased LXRα mRNA expression, activated ABCG5 and ABCG8 mRNA expression mediated by FXR as well as LXRα, enhanced FXR mRNA expression, and increased CYP7A1 mRNA expression mediated by the PPARγ and LXRα pathways, together or independently. CONCLUSION: Our data suggested that pravastatin prevents cholesterol gallstone diseases via the increase of FXR, LXRαand CYP7A1 in human hepatocytes. | Hyun Woo Byun Eun Mi Hong Soo Hee Park Dong Hee Koh Min Ho Choi Hyun Joo Jang Sea Hyub Kae Jin Lee | 2014 | Hepatobiliary & Pancreatic Diseases International2014，13，1： | 2 |

| 12 | Surgical Repair of Ventricular Septal Defect in Neonates: Indications and Outcomes显示文摘Background:The optimal surgical timing and clinical outcomes of ventricular septal defect(VSD)closure in neo-nates remain unclear.We aimed to evaluate the clinical outcomes of VSD closure in neonates(age≤30 days).Methods:We retrospectively reviewed 50 consecutive neonates who underwent VSD closure for isolated VSDs between August 2003 and June 2021.Indications for the procedure included congestive heart failure/failure to thrive and pulmonary hypertension.Major adverse events(MAEs)were defined as the composite of all-cause mortality,reoperation,persistent atrioventricular block,and significant(≥grade 2)valvular dysfunction.Results:The median age and body weight at operation were 26.0 days(interquartile range[IQR],18.8–28.3)and 3.7 kg(IQR,3.3–4.2),respectively.The median follow-up duration was 110.4 months(IQR,56.8–165.0).Seven patients required preoperative respiratory support,andfive had significant(≥grade 2)preoperative valvular dysfunction.One early mortality occurred due to irreversible cardiogenic shock;no late mortality was observed.One reopera-tion was due to hemodynamically significant residual VSD at 103.8 months postoperatively.The overall survival,freedom from reoperation,and freedom from MAE at 15-years were 98.0%,96.3%,and 94.4%,respectively.Pre-operative mechanical ventilation was associated with a longer duration of postoperative mechanical ventilation(p<0.001)and a longer length of intensive care unit stay(p<0.001).Conclusions:VSD closure with favorable outcomes without morbidities is feasible even in neonates.However,neonates requiring preoperative respiratory support may require careful postoperative management considering the long-term postoperative risks.Overall,surgical VSD closure might be indicated earlier in neonates with respiratory compromise. | Jae Hong Lee Sungkyu Cho Jae Gun Kwak Hye Won Kwon Woong-Han Kim Mi Kyoung Song Sang-Yun Lee Gi Beom Kim Eun Jung Bae | 2024 | Congenital Heart Disease2024，19，1： | 0 |
