| 1 | Helicobacter pylori infection is not associated with nonalcoholic fatty liver disease显示文摘AIM: To determine whether Helicobacter pylori(H. pylori) infection confers a higher risk of Nonalcoholic fatty liver disease(NAFLD).METHODS: Healthy people who underwent health screening were analyzed retrospectively. Inclusion criteria were age ≥ 20 years, history of H. pylori infection, and recorded insulin level. Participants were classified as H. pylori positive or negative according to 13 C urea breath tests. NAFLD was defined using the hepatic steatosis index(HSI) and NAFLD liver fat score(NAFLD-LFS). Those with an HSI > 36 or NAFLD-LFS >-0.640 were considered to have NAFLD. Multivariable logistic regression was performed to identify risk factors for NAFLD.RESULTS: Three thousand six hundred and sixtythree people were analyzed and 1636(44.7%) were H. pylori positive. H. pylori infection was associated with older age, male gender, hypertension, higher body mass index, and a dyslipidemic profile. HSI differed significantly between H. pylori positive and negative subjects(median 33.2, interquartile range(IQR) 30.0-36.2 for H. pylori-positive vs median 32.6, IQR 29.8-36.0 for negative participants, P = 0.005), but NAFLD-LSF did not [median-1.7, IQR-2.4--0.7 vs median-1.8, IQR-2.4-(-0.7), respectively, P = 0.122]. The percentage of people with NAFLD did not differbetween infected and uninfected groups: HIS, 26.9% vs 27.1%, P = 0.173; NAFLD-LFS, 23.5% vs 23.1%, P = 0.778. H. pylori infection was not a risk factor, but C-reactive protein concentration and smoking were significant risk factors for NAFLD.CONCLUSION: H. pylori infection is not a risk factor for NAFLD as indicated by HSI or NAFLD-LFS. Prospective, large-scale studies involving liver biopsies should be considered. | Myong Ki Baeg Seung Kew Yoon Sun-Hye Ko Yong-Sun Noh In-Seok Lee Myung-Gyu Choi | 2016 | World Journal of Gastroenterology2016，22，8： | 12 |
| 2 | Increased liver markers are associated with higher risk of type 2 diabetes显示文摘AIM: To investigate the association between liver markers and the risk of type 2 diabetes(T2DM) and impaired fasting glucose(IFG).METHODS: A total of 8863 participants(3408 men and 5455 women) over 30 years of age were analyzed from the fifth Korean National Health and Nutrition Examination Survey(2010-2011). The associations of serum liver markers such as aspartate aminotransferase(AST), alanine aminotransferase(ALT), AST/ALT, and gamma-glutamyltransferase(GGT) with T2 DM and IFG were analyzed using logistic regression models. Participants were divided into sex-specific quartiles on the basis of liver markers.RESULTS: The prevalence of T2 DM and IFG were 11.3% and 18.3%. Increasing quartiles of ALT and GGT were positively and AST/ALT were negatively correlated with T2 DM and IFG. Analysis of the liver marker combinations showed that if any two or more markers were in the highest risk quartile, the risks of both T2 DM and IFG increased significantly. The risk was greatest when the highest ALT and GGT and lowest AST/ALT quartile were combined, with the riskof T2 DM at 3.21(95%CI: 1.829-5.622, P < 0.001) in men and 4.60(95%CI: 3.217-6.582, P < 0.001) in women. Men and women with the highest AST and ALT and lowest AST/ALT quartile had a 1.99 and 2.40 times increased risk of IFG.CONCLUSION: Higher levels of GGT and ALT and lower AST/ALT within the physiological range are independent, additive risk factors of T2 DM and IFG. | Sun-Hye Ko Myong Ki Baeg Kyung-Do Han Seung-Hyun Ko Yu-Bae Ahn | 2015 | World Journal of Gastroenterology2015，21，24： | 8 |
| 3 | Case of inappropriate ADH syndrome:Hyponatremia due to polyethylene glycol bowel preparation显示文摘Colonoscopic screening has been reported to reduce deaths from colorectal cancer.Adequate bowel preparation is essential for this and safety is an important issue in choosing the methods.Polyethylene glycol(PEG)is regarded as a safe method for cleansing,especially compared with oral sodium phosphate.Here,we present a case of hyponatremia caused by the syndrome of inappropriate antidiuretic hormone(ADH)syndrome after PEG precolonoscopic cleansing resulting in generalized tonic-clonic seizures.A 62-year-old women had ingested PEG for precolonoscopic bowel cleansing.While waiting for the colonoscopy,she developed a stuporous mentality and generalized tonic-clonic seizures,which did not correlate with brain magnetic resonance imaging.Her serum sodium level was 113 mEq per liter and laboratory analyses were consistent with inappropriate ADH syndrome.Her thyroid and adrenal functions were normal.There were no malignancies,infections,respiratory disorders or central nervous disorders and she had no history of taking either diuretics or other medications,which might have caused inappropriate ADH syndrome.She was treated with 3%hypertonic saline and showed a complete neurological recovery as her sodium levels recovered.Follow-up visits showed the patient to have a normal sodium level without neurologic deficits.This case shows that inappropriate ADH syndrome can be caused by PEG preparation,which implies that physicians have to be aware of the possible side effects of this colonic cleansing approach and mindful of the possible ensuing symptoms. | Sun-Hye Ko Chul-Hyun Lim Jae-Young Kim Seung Hun Kang Myong Ki Baeg Hyun Jin Oh | 2014 | World Journal of Gastroenterology2014，20，34： | 5 |
| 4 | Antioxidative phytoceuticals to ameliorate pancreatitis in animal models: An answer from nature显示文摘Despite enthusiastic efforts directed at elucidating critical underlying mechanisms towards the identification of novel therapeutic targets for severe acute pancreatitis(SAP), the disease remains without a specific therapy to be executed within the first hours to days after onset of symptoms. Although earlier management for SAP should aim to either treat organ failure or reduce infectious complications, the current standard of care for the general management of AP in the first hours to days after onset of symptoms include intravenous fluid replacement, nutritional changes, and the use of analgesics with a close monitoring of vital signs. Furthermore, repeated evaluation of severity is very important, as the condition is particularly unstable in the early stages. In cases where biliary pancreatitis is accompanied by acute cholangitis or in cases where biliary stasis is suspected,an early endoscopic retrograde cholangiopancreatography is recommended.However,practice guidelines regarding the treatment of pancreatitis are suboptimal.In chronic pancreatitis,conservative management strategies include lifestyle modifications and dietary changes followed by analgesics and pancreatic enzyme supplementation.Recently,attention has been focused on phytoceuticals or antioxidants as agents that could surpass the limitations associated with currently available therapies.Because oxidative stress has been shown to play an important role in the pathogenesis of pancreatitis,antioxidants alone or combined with conventional therapy may improve oxidativestress-induced organ damage.Interest in phytoceuticals stems from their potential use as simple,accurate tools for pancreatitis prognostication that could replace older and more tedious methods.Therefore,the use of antioxidative nutrition or phytoceuticals may represent a new direction for clinical research in pancreatitis.In this review article,recent advances in the understanding of the pathogenesis of pancreatitis are discussed and the paradigm shift underway to develop phytoceuticals and antioxidants to treat it is introduced.Despite the promise of studies evaluating the effects of antioxidants/phytoceuticals in pancreatitis,translation to the clinic has thus far been disappointing.However,it is expected that continued research will provide solid evidence to justify the use of antioxidative phytoceuticals in the treatment of pancreatitis. | Jong-Min Park Sooyeon Lee Mi Kyung Chung Sung-Hun Kwon Eun-Hee Kim Kwang Hyun Ko Chang Il Kwon Ki Baik Hahm | 2014 | World Journal of Gastroenterology2014，20，44： | 5 |

| 6 | A case of a duodenal duplication cyst presenting as melena显示文摘Duodenal duplication cysts are benign rare congenital anomalies reported mainly in the pediatric population,but seldom in adults.Symptoms depend on the type and location and can present as abdominal pain,distension,dysphagia or dyspepsia.They have been reported to be responsible for duodenal obstruction,pancreatitis and,in rare cases,gastrointestinal bleeding.We present a case of a duodenal duplication cyst in a 43-year-old man presenting as melena.Initial gastroduodenoscopy and colonoscopy did not reveal any bleeding focus.However,the patient began passing melena after 3 d,with an acute decrease in hemoglobin levels.Subsequent studies revealed a duplication cyst in the second portion of the duodenum which was surgically resected.Histology revealed a duodenal duplication cyst consisting of intestinal mucosa.There was no further bleeding and the patient recovered completely.In rare cases,duodenal duplication cysts might cause gastrointestinal bleeding and should be included in the differential diagnosis. | Seung Yeon Ko Sun Hye Ko Sungeun Ha Mi Sung Kim Hyang Mi Shin Myong Ki Baeg | 2013 | World Journal of Gastroenterology2013，19，38： | 2 |

| 9 | Density functional theory study on the role of ternary alloying elements in TiFe-based hydrogen storage alloys显示文摘The role of additional ternary alloying elements on the performance of stationary TiFe-based hydrogen storage alloys was investigated based on first-principles density functional theory calculations.As a basic step for examinations,the site preference of each alloying element in the stoichiometric and nonstoichiometric B2TiFe compounds was clarified considering possible antisite defects.Based on the revealed site preference,the effect of various possible ternary elements on the hydrogen storage was examined by focusing on the formation enthalpies of TiFeH and TiFeH_(2) hydrides,which were closely related to the change in the location of plateaus in the pressure-composition-temperature curve.Several physical properties such as the volume expansion due to hydride formation were also examined to provide additional criteria for selecting optimum alloying conditions in future alloying design processes.Candidate alloying elements that maximize the grain boundary embrittlement due to the solute segregation were proposed for the enhanced initial activation of TiFe-based hydrogen storage alloys. | Won-Seok Ko Ki Beom Park Hyung-Ki Park | 2021 | Journal of Materials Science & Technology2021，，33： | 1 |

| 19 | Influence of a UV-ozone treatment on amorphous SnO_(2) electron selective layers for highly efficient planar MAPbI3 perovskite solar cells显示文摘The effect of ultraviolet-ozone(UVO)irradiation on amorphous(am)SnO_(2) and its impact on the photoconversion efficiency of MAPbI3-based perovskite solar cells were investigated in detail.UVO treatment was found to increase the amount of chemisorbed oxygen on the am-SnO_(2) surface,reducing the surface energy and contact angle.Physicochemical changes in the am-SnO_(2) surface lowered the Gibbs free energy for the densification of perovskite films and facilitated the formation of homogeneous perovskite grains.In addition,the Fermi energy of the UVO-treated am-SnO_(2) shifted upwards to achieve an ideal band offset for MAPbI3,which was verified by theoretical calculations based on the density functional theory.We achieved a champion efficiency of 19.01% with a statistical reproducibility of 17.01±1.34% owing to improved perovskite film densification and enhanced charge transport/extraction,which is considerably higher than the 13.78±2.15% of the counterpart.Furthermore,UVO-treated,am-SnO_(2)-based devices showed improved stability and less hysteresis,which is encouraging for the future application of up-scaled perovskite solar cells. | Kyungeun Jung Du Hyeon Kim Jaemin Kim Sunglim Ko Jae Won Choi Ki Chul Kim Sang-Geul Lee Man-Jong Lee | 2020 | Journal of Materials Science & Technology2020，59，24： | 1 |
