1Limited endoscopic sphincterotomy plus large balloon dilation for choledocholithiasis with periampullary diverticula显示文摘AIM: To investigate the effectiveness and safety of limited endoscopic sphincterotomy (EST) plus large balloon dilation (LBD) for removing choledocholithiasis in patients with periampullary diverticula (PAD). METHODS: A total of 139 patients with common bile duct (CBD) stones were treated with LBD (10-20 mm balloon diameter) after limited EST. Of this total, 73 patients had PAD and 66 patients did not have PAD (controls). The results of stone removal and complications were retrospectively evaluated. RESULTS: There were no significant differences between the PAD and the control groups in overall successful stone removal (94.5% vs 93.9%), stone removal in first session (69.9% vs 81.8%), mechanical lithotripsy (12.3% vs 13.6%), and complications (11.0% vs 7.6%). Clinical outcomes were also similar between the types of PAD, but the rate of stone removal in first session and the number of sessions were significantly lower and more frequent, respectively, in type B PAD (papilla located near the diverticulum) than controls [23/38 (60.5%) vs 54/66 (81.8%), P = 0.021; and 1 (1-2) vs 1 (1-3), P = 0.037, respectively] and the frequency of pancreatitis was significantly higher in type A PAD (papilla located inside or in the margin of the diverticulum) than in controls (16.1% vs 3.0%, P = 0.047). CONCLUSION: Limited EST plus LBD was an effective and safe procedure for removing choledocholithiasis in patients with PAD. However, some types of PAD should be managed with caution.Hyung Wook Kim Dae Hwan Kang Cheol Woong Choi Jong Hwan Park Jin Ho Lee Min Dae Kim Il Doo Kim Ki Tae Yoon Mong Cho Ung Bae Jeon Suk Kim Chang Won Kim Jun Woo Lee 2010World Journal of Gastroenterology2010,16,34:26
2Neoadjuvant chemoradiotherapy followed by D2 gastrectomy in locally advanced gastric cancer显示文摘AIM:To investigate the efficacy of neoadjuvant chemoradiotherapy(NACRT) for resectability of locally advanced gastric cancer(LAGC).METHODS:Between November 2007 and January 2014,29 patients with LAGC(clinically T3 with distal esophagus invasion/T4 or bulky regional node metastasis) that were treated with NACRT followed by D2 gastrectomy were included in this study.Resectability was evaluated with radiologic and endoscopic exams before and after NACRT.Using threedimensional conformal radiotherapy,patients received 45 Gy,with a daily dose of 1.8 Gy.The entire tumor extent and the regional metastatic lymph nodes were included in the gross tumor volume.Patients presenting with a resectable tumor after NACRT received a total or subtotal gastrectomy with D2 dissection.The pathologic tumor response was evaluated using Japanese Gastric Cancer Association histologic evaluation criteria.Postoperative morbidity was evaluated using the National Cancer Institute-Common Terminology Criteria for Adverse Events version 4.0.Overall survival(OS) and progression-free survival(PFS) rates were estimated using a Kaplan-Meier analysis and compared using the log-rank test.RESULTS:All patients were assessed as unresectable cases.Twenty-four patients(24/29; 82.8%) showed LAGC on positron emission tomography-computed tomography(CT) and contrast-enhanced CT,whereas four patients(4/29; 13.8%) with vague invasion orabutment to an adjacent organ underwent diagnostic laparoscopy.One patient(1/29; 3.4%),initially assessed as a resectable case,underwent an 'open and closure' after the tumor was found to be unresectable.Abutment to an adjacent organ(34.5%) was the most common reason for NACRT.The clinical response rate one month after NACRT was 44.8%.After NACRT,69%(20/29) of patients had a resectable tumor.Of the 20 patients with a resectable tumor,18 patients(62.1%) underwent a D2 gastrectomy.The R0 resection rate was 94.4% and two patients(2/18; 11.1%) showed a complete response.The median follow-up duration was 13.5 mo.The one-year OS and PFS rates were 72.4 and 48.9%,respectively.The one-year OS,PFS,local failure-free survival,and distant metastasis-free survival were higher in patients with a resectable tumor after NACRT(P < 0.001,P < 0.001,P < 0.001,and P =0.078,respectively).No grade 3-4 late treatment-related toxicities or postoperative mortalities were observed.CONCLUSION:NACRT with D2 gastrectomy showed a high rate of R0 resection and promising local control,which may increase the R0 resection opportunity resulting in survival benefit.Mi Sun Kim Joon Seok Lim Woo Jin Hyung Yong Chan Lee Sun Young Rha Ki Chang Keum Woong Sub Koom 2015World Journal of Gastroenterology2015,21,9:15
3Prevalence of clonorchiasis in patients with gastrointestinal disease: A Korean nationwide multicenter survey显示文摘AIM: To investigate prevalence of Clonorchis sinensis in patients with gastrointestinal symptoms, and the relation of the infection to hepatobiliary diseases in 26 hospitals in Korea.METHODS: Consecutive patients who had been admitted to the Division of Gastroenterology with gastrointestinal symptoms were enrolled from March to April 2005. Of those who had been diagnosed with clonorchiasis, epidemiology and correlation between infection and hepatobiliary diseases were surveyed by questionnaire.RESULTS: Of 3080 patients with gastrointestinal diseases, 396 (12.9%) had clonorchiasis and 1140 patients (37.2%) had a history of eating raw freshwater fish. Of those with a history of raw freshwater fish ingestion, 238 (20.9%) patients had clonorchiasis. Cholangiocarcinoma was more prevalent in C. sinensis-infected patients than non-infected patients [34/396 (8.6%) vs 145/2684 (5.4%), P = 0.015]. Cholangiocarcinoma and clonorchiasis showed statistically significant positive cross-relation (P = 0.008). Choledocholithiasis, cholecystolithiasis, cholangitis, hepatocellular carcinoma, and biliary pancreatitis did not correlate with clonorchiasis.CONCLUSION: Infection rate of clonorchiasis was still high in patients with gastrointestinal diseases in Korea, and has not decreased very much during the last two decades. Cholangiocarcinoma was related to clonorchiasis, which suggested an etiological role for the parasite.Ho Gak Kim Jimin Han Myung-Hwan Kim Kyu Hyun Cho Im Hee Shin Gwang Ha Kim Jae Seon Kim Jin Bong Kim Tae Nyeun Kim Tae Hyeon Kim Tae Hyo Kim Jae Woo Kim Ji Kon Ryu Young-Soo Moon Jong Ho Moon Sung Jae Park Chan Guk Park Sung-Jo Bang Chang Heon Yang Kyo-Sang Yoo Byung Moo Yoo Kyu Taek Lee Dong Ki Lee Byung Seok Lee Sang Soo Lee Seung Ok Lee Woo Jin Lee Chang Min Cho Young-Eun Joo Gab Jin Cheon Young Woo Choi Jae Bok Chung Yong Bum Yoon 2009World Journal of Gastroenterology2009,15,1:15
4Endoscopic submucosal dissection for early gastric cancer with undifferentiated-type histology:A meta-analysis显示文摘AIM: To evaluate the efficacy and safety of endoscopicsubmucosal dissection(ESD) for early gastric cancer(EGC) with undifferentiated-type histology.METHODS: A systematic literature review was conducted using the core databases. Complete resection,curative resection, en bloc resection, recurrence and adverse event rate were extracted and analyzed. A random effect model was applied. The methodological quality of the enrolled studies was assessed using the Newcastle-Ottawa Scale. Publication bias was evaluated using a funnel plot, the trim and fill method, Egger's test,and a rank correlation test.RESULTS: Fourteen retrospective studies between2009 and 2014 were identified(972 EGC lesions with undifferentiated-type histology). The total en bloc and complete resection rates were estimated as92.1%(95%CI: 87.4%-95.2%) and 77.5%(95%CI:69.3%-84%), respectively. The total curative resection rate was 61.4%(95%CI: 44.5%-75.9%). The overall recurrence rate was 7.6%(95%CI: 3.4%-16%).Limited to histologically diagnosed expanded-criteria lesions, the en bloc and complete resection rates were91.2% and 85.6%, respectively. The curative resection rate was 79.8%.CONCLUSION: In this analysis, ESD is a technically feasible treatment modality for EGC with undifferentiatedtype histology. Long-term studies are needed to confirm these therapeutic outcomes.Chang Seok Bang Gwang Ho Baik In Soo Shin Jing Bong Kim Ki Tae Suk Jai Hoon Yoon Yeon Soo Kim Dong Joon Kim Woon Geon Shin Kyung Ho Kim Hak Yang Kim Hyun Lim Ho Seok Kang Jong Hyeok Kim Jin Bae Kim Sung Won Jung Sea Hyub Kae Hyun Joo Jang Min Ho Choi 2015World Journal of Gastroenterology2015,21,19:14
5Effect of Korean red ginseng on blood pressure and nitric oxide production显示文摘AIM: To investigate the effect of crude saponin and non-saponin fraction of Korean red ginseng (KRG) on the blood pressure and nitric oxide (NO) production in the conscious rats and cultured endothelial cell line, ECV 304 cells. METHODS: Systolic blood pressure and heart rate were monitored in the conscious rats. Nitric oxide levels and the expression of nitric oxide synthase were measured by a spectrophotometric assay using Griess reagents and Western blotting, respectively. Nitric-oxide synthase activity was measured based on the conversion rate of [3H]arginine to [3H]citrulline. RESULTS: Systolic blood pressure was decreased by crude saponin (100 mg/kg, iv) of KRG in the conscious control and one-kidney, one-clip Goldblatt hypertensive (IK, 1C-GBH) rats. The hypotensive effect induced by crude saponin of KRG reached maximum at 2 - 4 min and slowly recovered after 20 min to the initial level in both groups. Crude saponin of KRG induced tachycardia in the conscious rats but induced bradycardia in theJEON Byeong Hwa KIM Cuk Seong KIM Hoe-Suk PARK Jin-Bong NAM Ki Yeul CHANG Seok Jong 2000Acta Pharmacologica Sinica2000,21,12:12

7Iodized 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 2009World Journal of Gastroenterology2009,15,46:8
8Clinical significance and risk factors of postembolization fever in patients with hepatocellular carcinoma显示文摘AIM:To investigate tumor response and survival in patients with postembolization fever(PEF) and to determine the risk factors for PEF.METHODS:Four hundred forty-three hepatocellular carcinoma(HCC) patients who underwent the first session of transcatheter arterial chemoembolization(TACE) between January 2005 and December 2009 were analyzed retrospectively.PEF was defined as a body temperature greater than 38.0 ℃ that developed within 3 d of TACE without evidence of infection.The tumor progression-free interval was defined as the interval from the first TACE to the second TACE based on mRECIST criteria.Clinical staging was based on the American Joint Committee on Cancer tumor,node,metastases(TNM) classification of malignant tumors.All patients were admitted before their 1 st TACE treatment,and blood samples were obtained from all patients before and after treatment.Clinicoradiological variables and host-related variables were compared between two groups:patients with PEF vs patients without PEF.Additionally,variables related to 20-mo mortality and tumor progression-free survival were analyzed.RESULTS:The study population comprised 370(85.4%) men and 73(14.6%) women with a mean age of 62.29 ± 10.35 years.A total of 1836 TACE sessions were conducted in 443 patients,and each patient received between 1 and 27(mean:4.14 ± 3.57) TACE sessions.The mean follow-up duration was 22.23 ± 19.6 mo(range:0-81 mo).PEF developed in 117 patients(26.41%) at the time of the first TACE session.PEF was not associated with 20-mo survival(P = 0.524) or computed tomography(CT) response(P = 0.413) in a univariate analysis.A univariate analysis further indicated that diffuse-type HCC(P = 0.021),large tumor size(≥ 5 cm)(P = 0.046),lipiodol dose(≥ 7 mL,P = 0.001),poor blood glucose control(P = 0.034),alanine aminotransferase(ALT) value after TACE(P = 0.004) and C-reactive protein(CRP) value after TACE(P = 0.036) served as possible risk factors correlated with PEF.The ALT value after TACE(P = 0.021) and lipiodol dose over 7 mL(P = 0.011) were independent risk factors for PEF in the multivariate analysis.For the 20-mo survival,poor blood sugar control(P < 0.001),portal vein thrombosis(P = 0.001),favorable CT response after TACE(P < 0.001),initial aspartate aminotransferase(P = 0.02),initial CRP(P = 0.042),tumor size(P < 0.001),TNM stage(P < 0.001) and lipiodol dose(P < 0.001) were possible risk factors in the univariate analysis.Tumor size(P = 0.03),poor blood sugar control(P = 0.043),and portal vein thrombosis(P = 0.031) were significant predictors of survival in the multivariate analysis.Furthermore,the tumor progression-free interval was closely associated with CRP > 1 mg/dL(P = 0.003),tumor size > 5 cm(P < 0.001),tumor type(poorly defined)(P < 0.001),and lipiodol dose(> 7 mL,P < 0.001).CONCLUSION:PEF has no impact on survival at 20 mo or radiologic response.However,the ALT level after TACE and the lipiodol dose represent significant risk factors for PEF.Chung Hwan Jun Ho Seok Ki Hoon Ki Lee Kang Jin Park Seon Young Park Sung Bum Cho Chang Hwan Park Young Eun Joo Hyun Soo Kim Sung Kyu Choi Jong Sun Rew 2013World Journal of Gastroenterology2013,19,2:7
9Absolute monocyte and lymphocyte count prognostic score for patients with gastric cancer显示文摘AIM:To measure the prognostic significance of absolute monocyte count/absolute lymphocyte count prognostic score(AMLPS) in patients with gastric cancer.METHODS:We retrospectively examined the combination of absolute monocyte count(AMC) and absolute lymphocyte count(ALC) as prognostic variables in a cohort of 299 gastric cancer patients who underwent surgical resection between 2006 and 2013 and were followed at a single institution.Both AMC and ALC were dichotomized into two groups using cut-off points determined by receiving operator characteristic curve analysis.An AMLPS was generated,which stratified patients into three risk groups:low risk(both low AMC and high ALC),intermediate risk(either high AMC or low ALC),and high risk(both high AMC and low ALC).The primary objective of the study was to validate the impact of AMLPS on both disease-free survival(DFS) and overall survival(OS),and the second objective was to assess the AMLPS as an independent prognostic factor for survival in comparison with known prognostic factors.RESULTS:Using data from the entire cohort,the most discriminative cut-off values of AMC and ALC selected on the receiver operating characteristic curve were 672.4/μL and 1734/μL for DFS and OS.AMLPS risk groups included 158(52.8%) patients in the lowrisk,128(42.8%) in the intermediate-risk,and 13(4.3%) in the high-risk group.With a median followup of 37.2 mo(range:1.7-91.4 mo),five-year DFS rates in the low-,intermediate-,and high-risk groups were 83.4%,78.7%,and 19.8%,respectively.And fiveyear OS rates in the low-,intermediate-,and high-risk groups were 89.3%,81.1%,and 14.4%,respectively.On multivariate analysis performed with patient- and tumor-related factors,we identified AMLPS,age,and pathologic tumor-node-metastasis stage as the most valuable prognostic factors impacting DFS and OS.CONCLUSION:AMLPS identified patients with a poor DFS and OS,and it was independent of age,pathologic stage,and various inflammatory markers.Wan Kyu Eo Da Wun Jeong Hye Jung Chang Kyu Yeoun Won Sung Il Choi Se Hyun Kim Sung Wook Chun Young Lim Oh Tae Hwa Lee Young Ok Kim Ki Hyung Kim Yong Il Ji Ari Kim Heung Yeol Kim 2015World Journal of Gastroenterology2015,21,9:6
10Amomum villosum induces longitudinal bone growth in adolescent female rats显示文摘OBJECTIVE:This study was conducted to evaluate the effect of Amomum villosum on longitudinal bone growth.METHODS:Adolescent female Sprague-Dawley rats were divided into 3 groups and treated for 4 days:control(distilled water,p.o.),recombinant human growth hormone(rhGH;100 μg/kg,s.c.),and A.villosum(500 mg/kg,p.o.) groups.On day 3,tetracycline(20 g/kg,i.p.) was injected for growth plate identification.On days 2,3 and 4,5-bromo-2'-deoxyuridine(BrdU)(50 mg/kg,i.p.) was injected to label proliferating cells.On day 5,tibias were dissected and fixed in 4% paraformaldehyde,dehydrated,and sectioned for immunohistochemistry and histomorphometry.RESULTS:The rate of bone growth in the A.villosum and rhGH groups increased to(410 ± 44) and(389 ± 46) μm/day(P<0.01),respectively,as compared with the control(330.7 ± 34.7) μm/day.The thickness of the growth plates also increased to(591 ± 37) and(598 ± 32) μm,respectively,as compared with the control(524± 89) μm(P<0.001).The number of BrdU-positive cells in the chondrocytes of the A.villosum and rhGH groups was also significantly higher(126±24) and(143±18) cells/mm 2,respectively) than in the control(109 ± 25) mm 2(P<0.05).Insulin-like growth factor-1 and bone morphogenetic protein-2 in the A.villosum and rhGH groups were highly expressed in the growth plate as compared with the control samples,indicating increased bone formation.CONCLUSIONS:A.villosum could be used to treat growth retardation during adolescence.Sun Haeng Lee Ji Young Kim Hocheol Kim Seul Ki Park Cho Young Kim Sun Yong Chung Gyu Tae Chang 2012Journal of Traditional Chinese Medicine2012,32,3:6

12Assessment 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 2016World Journal of Gastroenterology2016,22,41:5
13Antioxidative 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 2014World Journal of Gastroenterology2014,20,44:5
14Appropriate empirical antibiotic use and 30-d mortality in cirrhotic patients with bacteremia显示文摘AIM: To analyze whether prompt and appropriate empirical antibiotic(AEA) use is associated with mortality in cirrhotic patients with bacteremia. METHODS: A total of 102 episodes of bacteremia in 72 patients with cirrhosis were analyzed. AEA was defined as a using or starting an antibiotic appropriate to the isolated pathogen at the time of bacteremia. The primary endpoint was 30-d mortality. RESULTS: The mortality rate at 30 d was 30.4%(31/102 episodes). Use of AEA was associated with better survival at 30 d(76.5% vs 46.9%, P = 0.05), and inappropriate empirical antibiotic(IEA) use was an independent factor associated with increased mortality(OR = 3.24; 95%CI: 1.50-7.00; P = 0.003, adjusted for age, sex, ChildPugh Class, gastrointestinal bleeding, presence of septic shock). IEA use was more frequent when the isolated pathogen was a multiresistant pathogen, and when infection was healthcare-related or hospital-acquired. CONCLUSION: AEA use was associated with increased survival of cirrhotic patients who developed bacteremia. Strategies for AEA use, tailored according to the local epidemiological patterns, are needed to improve survival of cirrhotic patients with bacteremia.Hyun Park Ki Jun Jang Won Jang Sang Hoon Park Ji Young Park Tae Joo Jeon Tae Hoon Oh Won Chang Shin Won-Choong Choi Dong Hyun Sinn 2015World Journal of Gastroenterology2015,21,12:4

16Clinical characteristics of peptic ulcer perforation in Korea显示文摘AIM To elucidate the epidemiological characteristics and associated risk factors of perforated peptic ulcer(PPU).METHODS We retrospectively reviewed medical records of patients who were diagnosed with benign PPU from 2010 through 2015 at 6 Hallym university-affiliated hospitals.RESULTS A total of 396 patients were identified with postoperative complication rate of 9.1% and mortality rate of 0.8%. Among 174(43.9%) patients who were examined for Helicobacter pylori(H. pylori) infection, 78(44.8%) patients were positive for H. pylori infection, 21(12.1%) were on non-steroidal anti-inflammatory drugs(NSAIDs) therapy, and 80(46%) patients were neither infected of H. pylori nor treated by any kinds of NSAIDs. Multivariate analysis indicated that older age(OR = 1.09, 95%CI: 1.04-1.16) and comorbidity(OR = 4.11, 95%CI: 1.03-16.48) were risk factors for NSAID-associated PPU compared with non-H. pylori, non-NSAID associated PPU and older age(OR = 1.04, 95%CI: 1.02-1.07) and alcohol consumption(OR = 2.08, 95%CI: 1.05-4.13) were risk factors for non-H. pylori, non-NSAID associated PPU compared with solely H. pylori positive PPU.CONCLUSION Elderly patients with comorbidities are associated with NSAIDs-associated PPU. Non-H. pylori, non-NSAID peptic ulcer is important etiology of PPU and alcohol consumption is associated risk factor.Young Joo Yang Chang Seok Bang Suk Pyo Shin Tae Young Park Ki Tae Suk Gwang Ho Baik Dong Joon Kim 2017World Journal of Gastroenterology2017,23,14:4

18Characteristics of nonvariceal upper gastrointestinal hemorrhage in patients with chronic kidney disease显示文摘AIM:To evaluate the clinical characteristics of nonvariceal upper gastrointestinal hemorrhage(NGIH)in patients with chronic kidney disease(CKD).METHODS:From 2003 to 2010,a total of 72 CKD patients(male n=52,72.2%;female n=20,27.8%)who had undergone endoscopic treatments for NGIH were retrospectively identified.Clinical findings,endoscopic features,prognosis,rebleeding risk factors,and mortality-related factors were evaluated.The characteristics of the patients and rebleeding-related data were recorded for the following variables:gender,age,alcohol use and smoking history,past hemorrhage history,endoscopic findings(the cause,location,and size of the hemorrhage and the hemorrhagic state),therapeutic options for endoscopy,endoscopist experience,clinical outcomes,and mortality.RESULTS:The average size of the hemorrhagic site was 13.7±10.2 mm,and the most common hemorrhagic site in the stomach was the antrum(n=21,43.8%).The most frequent method of hemostasis was combination therapy(n=32,44.4%).The incidence of rebleeding was 37.5%(n=27),and 16.7%(n=12)of patients expired due to hemorrhage.In a multivariate analysis of the risk factors for rebleeding,alcoholism(OR=11.19,P=0.02),the experience of endoscopists(OR=0.56,P=0.03),and combination endoscopic therapy(OR=0.06,P=0.01)compared with monotherapy were significantly related to rebleeding after endoscopic therapy.In a risk analysis of mortality after endoscopic therapy,only rebleeding was related to mortality(OR=7.1,P=0.02).CONCLUSION:Intensive combined endoscopic treatments by experienced endoscopists are necessary for the treatment of NGIH in patients with CKD,especially when a patient is an alcoholic.Chang Seok Bang Yong Seop Lee Yun Hyeong Lee Hotaik Sung Hong Jun Park Hyun Soo Kim Jin Bong Kim Gwang Ho Baik Yeon Soo Kim Jai Hoon Yoon Dong Joon Kim Ki Tae Suk 2013World Journal of Gastroenterology2013,19,43:3
19Memristive Devices Based on Two-Dimensional Transition Metal Chalcogenides for Neuromorphic Computing显示文摘Two-dimensional(2D)transition metal chalcogenides(TMC)and their heterostructures are appealing as building blocks in a wide range of electronic and optoelectronic devices,particularly futuristic memristive and synaptic devices for brain-inspired neuromorphic computing systems.The distinct properties such as high durability,electrical and optical tunability,clean surface,flexibility,and LEGO-staking capability enable simple fabrication with high integration density,energy-efficient operation,and high scalability.This review provides a thorough examination of high-performance memristors based on 2D TMCs for neuromorphic computing applications,including the promise of 2D TMC materials and heterostructures,as well as the state-of-the-art demonstration of memristive devices.The challenges and future prospects for the development of these emerging materials and devices are also discussed.The purpose of this review is to provide an outlook on the fabrication and characterization of neuromorphic memristors based on 2D TMCs.Ki Chang Kwon Ji Hyun Baek Kootak Hong Soo Young Kim Ho Won Jang 2022Nano-Micro Letters2022,14,4:3
20High tibial osteotomy with human umbilical cord blood-derived mesenchymal stem cells implantation for knee cartilage regeneration显示文摘BACKGROUND High tibial osteotomy(HTO)is a well-established method for the treatment of medial compartment osteoarthritis of the knee with varus deformity.However,HTO alone cannot adequately repair the arthritic joint,necessitating cartilage regeneration therapy.Cartilage regeneration procedures with concomitant HTO are used to improve the clinical outcome in patients with varus deformity.AIM To evaluate cartilage regeneration after implantation of allogenic human umbilical cord blood-derived mesenchymal stem cells(hUCB-MSCs)with concomitant HTO.METHODS Data for patients who underwent implantation of hUCB-MSCs with concomitant HTO were evaluated.The patients included in this study were over 40 years old,had a varus deformity of more than 5°,and a full-thickness International Cartilage Repair Society(ICRS)grade IV articular cartilage lesion of more than 4 cm2 in the medial compartment of the knee.All patients underwent second-look arthroscopy during hardware removal.Cartilage regeneration was evaluated macroscopically using the ICRS grading system in second-look arthroscopy.We also assessed the effects of patient characteristics,such as trochlear lesions,age,and lesion size,using patient medical records.RESULTS A total of 125 patients were included in the study,with an average age of 58.3±6.8 years(range:43-74 years old);95(76%)were female and 30(24%)were male.The average hip-knee-ankle(HKA)angle for measuring varus deformity was 7.6°±2.4°(range:5.0-14.2°).In second-look arthroscopy,the status of medial femoral condyle(MFC)cartilage was as follows:73(58.4%)patients with ICRS grade I,37(29.6%)with ICRS grade II,and 15(12%)with ICRS grade III.No patients were staged with ICRS grade IV.Additionally,the scores[except International Knee Documentation Committee(IKDC)at 1 year]of the ICRS grade I group improved more significantly than those of the ICRS grade II and III groups.CONCLUSION Implantation of hUCB-MSCs with concomitant HTO is an effective treatment for patients with medial compartment osteoarthritis and varus deformity.Regeneration of cartilage improves the clinical outcomes for the patients.Jun-Seob Song Ki-Taek Hong Chae-Gwan Kong Na-Min Kim Jae-Yub Jung Han-Soo Park Young Ju Kim Ki Bong Chang Seok Jung Kim 2020World Journal of Stem Cells2020,12,6:3
