1Small sphincterotomy combined with endoscopic papillary large balloon dilation versus sphincterotomy显示文摘AIM:To compare small sphincterotomy combined with endoscopic papillary large balloon dilation(SES+ ELBD)and endoscopic sphincterotomy(EST)for large bile duct stones. METHODS:We compared prospectively SES+ELBD (group A,n=27)with conventional EST(group B, n=28)for the treatment of large bile duct stones(≥ 15 mm).When the stone could not be removed with a normal basket,mechanical lithotripsy was performed. We compared the rates of complete stone removal with one session and application of mechanical lithotripsy. RESULTS:No significant differences were observed in the mean largest stone size(A:20.8 mm,B:21.3 mm), bile duct diameter(A:21.4 mm,B:20.5 mm),number of stones(A:2.2,B:2.3),or procedure time(A:18 min, B:19 min)between the two groups.The rates of complete stone removal with one session was 85%in group A and 86%in group B(P=0.473).Mechanical lithotripsy was required for stone removal in nine of 27 patients(33%)in group A and nine of 28 patients (32%,P=0.527)in group B.CONCLUSION:SES+ELBD did not show significant benefits compared to conventional EST,especially for the removal of large(≥15 mm)bile duct stones.Hyun Gun Kim Young Koog Cheon Young Deok Cho Jong Ho Moon Do Hyun Park Tae Hoon Lee Hyun Jong Choi Sang-Heum Park Joon Seong Lee Moon Sung Lee 2009World Journal of Gastroenterology2009,15,34:34

3Histologic characteristics of gastric polyps in Korea: Emphasis on discrepancy between endoscopic forceps biopsy and endoscopic mucosal resection specimen显示文摘瞄准:在朝鲜人口调查胃的息肉的组织学的特征。方法:我们与胃的息肉考察了内视镜的相片和病人的医药记录通过 2003 年 2 月从 1996 年 4 月经历了内视镜的粘膜切除术。结果:从 74 个病人的 85 胃的息肉的一个总数被考察。Male-to-female 比率是 1:1.96。吝啬的年龄是 59.9 +/- 10.8 年。多重息肉在 10.8% 被观察。胃的息肉最经常发生在窦(58.8%) 。resected 标本上的病理学的结果如下:管状腺瘤 45.9% ,增生的息肉 31.8% ,煽动性的息肉 9.4% ,错构瘤 3.5% ,底的腺息肉 2.4% , tubulovillous 腺瘤 2.4% ,腺癌 2.4% ,发育异常 1.1% ,并且粘膜 pseudolipomatosis 1.1% 。在 resected 标本的内视镜的活体检视和病理之间的差异率是 27.1% 。在息肉和词语索引率的尺寸之间没有关系。结论:在在内视镜的钳活体检视和 resected 标本之间的 histologic 调查结果有可观的差异。全部息肉的组织学的评论的途径应该被执行,特别当一个腺瘤被怀疑时。Won Jae Yoon Dong Ho Lee Yong Jin Jung Ji Bong Jeong Ji Won Kim Byeong Gwan Kim Kook Lae Lee Kwang Hyuck Lee Young Soo Park Jin-Hyeok Hwang Jin-Wook Kim Nayoung Kim Jun Kyu Lee Hyun Chae Jung Yong Bum Yoon In Sung Song 2006World Journal of Gastroenterology2006,12,25:19
4Overexpression of the M2 isoform of pyruvate kinase is an adverse prognostic factor for signet ring cell gastric cancer显示文摘AIM:To investigate M2 isoform of pyruvate kinase(PKM2) expression in gastric cancers and evaluate its potential as a prognostic biomarker and an anticancer target.METHODS:All tissue samples were derived from gastric cancer patients underwent curative gastrectomy as a primary treatment.Clinical and pathological information were obtained from the medical records.Gene expression microarray data from 60 cancer and 19 noncancer gastric tissues were analyzed to evaluate the expression level of PKM2 mRNA.Tissue microarrays were constructed from 368 gastric cancer patients.Immunohistochemistry was used to measure PKM2 expression and PKM2 positivity of cancer was determined by proportion of PKM2-positive tumor cells and staining intensity.Association between PKM2 expression and the clinicopathological factors was evaluated and the correlation between PKM2 and cancer prognosis was evaluated.RESULTS:PKM2 mRNA levels were increased more than 2-fold in primary gastric cancers compared to adjacent normal tissues from the same patients(log transformed expression level:7.6 ± 0.65 vs 6.3 ± 0.51,P < 0.001).Moreover,differentiated type cancers had significantly higher PKM2 mRNA compared to undifferentiated type cancers(log transformed expression level:7.8 ± 0.70 vs 6.7 ± 0.71,P < 0.001).PKM2 protein was mainly localized in the cytoplasm of primary cancer cells and detected in 144 of 368(39.1%) human gastric cancer cases.PKM2 expression was not related with stage(P = 0.811),but strongly correlated with gastric cancer differentiation(P < 0.001).Differentiated type cancers expressed more PKM2 protein than did the undifferentiated ones.Well differentiated adenocarcinoma showed 63.6% PKM2-positive cells;in contrast,signet-ring cell cancers showed only 17.7% PKM2-positive cells.Importantly,PKM2 expression was correlated with shorter overall survival(P < 0.05) independent of stage only in signet-ring cell cancers.CONCLUSION:PKM2 expression might be an adverse prognostic factor for signet-ring cell carcinomas.Its function and potential as a prognostic marker should be further verified in gastric cancer.Jae Yun Lim Sun Och Yoon So Young Seol Soon Won Hong Jong Won Kim Seung Ho Choi Jae Yong Cho 2012World Journal of Gastroenterology2012,18,30:19
5The dynamics of the piglet gut microbiome during the weaning transition in association with health and nutrition显示文摘Background: Understanding the composition of the microbial community and its functional capacity during weaning is important for pig production as bacteria play important roles in the pig's health and growth performance. However,limited information is available regarding the composition and function of the gut microbiome of piglets in early-life.Therefore, we performed 16 S rRNA gene and whole metagenome shotgun sequencing of DNA from fecal samples from healthy piglets during weaning to measure microbiome shifts, and to identify the potential contribution of the early-life microbiota in shaping piglet health with a focus on microbial stress responses, carbohydrate and amino acid metabolism.Results: The analysis of 16 S rR NA genes and whole metagenome shotgun sequencing revealed significant compositional and functional differences between the fecal microbiome in nursing and weaned piglets. The fecal microbiome of the nursing piglets showed higher relative abundance of bacteria in the genus Bacteroides with abundant gene families related to the utilization of lactose and galactose. Prevotel a and Lactobacil us were enriched in weaned piglets with an enrichment for the gene families associated with carbohydrate and amino acid metabolism. In addition, an analysis of the functional capacity of the fecal microbiome showed higher abundances of genes associated with heat shock and oxidative stress in the metagenome of weaned piglets compared to nursing piglets.Conclusions: Overal, our data show that microbial shifts and changes in functional capacities of the piglet fecal microbiome resulted in potential reductions in the effects of stress, including dietary changes that occur during weaning.These results provide us with new insights into the piglet gut microbiome that contributes to the growth of the animal.Robin B.Guevarra Sang Hyun Hong Jin Ho Cho Bo-Ra Kim Jiwon Shin Jun Hyung Lee Bit Na Kang Young Hwa Kim Suphot Wattanaphansak Richard E.Isaacson Minho Song Hyeun Bum Kim 2018Journal of Animal Science and Biotechnology2018,9,4:16
6Gender differences in ghrelin, nociception genes, psychological factors and quality of life in functional dyspepsia显示文摘AIM to evaluate gender differences in the aspect of ghrelin,nociception-related genes and psychological aspects and the quality of life(Qo L) in Korean functional dyspepsia(FD) patients.METHODS Total of 191 persons were prospectively enrolled between March 2013 and May 2016 in Seoul National Bundang Hospital,and classified into control and FD group based on ROME Ⅲ criteria. Questionnaire included assessment for dyspepsia symptoms,Qo L and anxiety or depression. Preproghrelin and nociception genes in the gastric mucosa and plasma acyl/des-acyl ghrelin were measured. RESULTS Lower level of plasma acyl ghrelin in FD patients compared to control was significant only in male(15.9 fmol/m L vs 10.4 fmol/m L,P = 0.017). Significantly higher m RNA expressions of nerve growth factor and transient receptor potential vanilloid receptor 1 were observed in male(P = 0.002 and P = 0.014,respectively) than in female. In contrast,female FD patients had a higher anxiety and depression score than male FD(P = 0.029),and anxiety score was correlated with epigastric pain only in female FD patients(female: Spearman rho = 0.420,P = 0.037). The impairment of overall Qo L was more prominent in female FD patients than male patients(5.4 ± 0.3 vs 6.5 ± 0.3,P = 0.020). CONCLUSION Gender differences of ghrelin and nociception-related genes in male and psychological factors in female underlie FD symptoms. More careful assessment of psychological or emotional status is required particularly for the female FD patients.Yoon Jin Choi Young Soo Park Nayoung Kim Yong Sung Kim Sun Min Lee Dong Ho Lee Hyun Chae Jung 2017World Journal of Gastroenterology2017,23,45:16

8Effect of itopride, a new prokinetic, in patients with mild GERD: A pilot study显示文摘AIM: Itopride is a newly developed prokinetic agent, which enhances gastric motility through both antidopaminergic and anti-acetylcholinesterasic actions. The importance of esophageal motor dysfunction in the pathogenesis of gastro-esophageal reflux disease (GERD) makes it interesting to examine the effect of itopride on esophageal acid exposure.METHODS: The effect of itopride on esophageal acid reflux variables for 24 h was studied in 26 patients with GERD symptoms, pre-entry total acid exposure time (pH<4) of more than 5% and mild esophagitis (SavaryMiller grades Ⅰ, Ⅱ) proven by endoscopy. Ambulatory 24-h pH-metry and symptom assessment were performed after treatments with 150 or 300 mg itopride thrice a day (t.i.d.) for 30 d in random order, using an open label method.For evaluating the safety of itopride, blood biochemical laboratory test was performed and the serum prolactin level was also examined before and after treatment.RESULTS: Total symptom score was significantly decreased after treatment in 150- or 300-mg group. Itopride 300mg was significantly effective than 150 mg on decreasing the total per cent time with pH<4, total time with pH<4and DeMeester score. No serious adverse effects were observed with administration of itopride in both groups.CONCLUSION: Itopride 100 mg t.i.d, is effective on decreasing pathologic reflux in patient with GERD and therefore it has the potential to be effective in the treatment of this disease.Yong Sung Kim Tae Hyeon Kim Chang Soo Choi Young Woo Shon Sang Wook Kim Geom Seog Seo Yong Ho Nah Myung Gyu Choi Suck Chei Choi 2005World Journal of Gastroenterology2005,11,27:15
9Prevalence 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

13Endoscopic ultrasonography does not differentiate neoplastic from non-neoplastic small gallbladder polyps显示文摘AIM:To assess the ability of endoscopic ultrasonography(EUS) to differentiate neoplastic from non-neoplastic polypoid lesions of the gallbladder(PLGs) .METHODS:The uses of EUS and transabdominal ultrasonography(US) were retrospectively analyzed in 94 surgical cases of gallbladder polyps less than 20 mm in diameter.RESULTS:The prevalence of neoplastic lesions with a diameter of 5-10 mm was 17.2%(10/58) ;11-15 mm,15.4%(4/26) ,and 16-20 mm,50%(5/10) .The overall diagnostic accuracies of EUS and US for small PLGs were 80.9% and 63.9%(P < 0.05) ,respectively.EUS correctly distinguished 12(63.2%) of 19 neoplastic PLGs but was less accurate for polyps less than 1.0 cm(4/10,40%) than for polyps greater than 1.0 cm(8/9,88.9%) (P = 0.02) .CONCLUSION:Although EUS was more accurate than US,its accuracy for differentiating neoplastic from non-neoplastic PLGs less than 1.0 cm was low.Thus,EUS alone is not suffi cient for determining a treatment strategy for PLGs of less than 1.0 cm.Young Koog Cheon Won Young Cho Tae Hee Lee Young Deok Cho Jong Ho Moon Joon Seong Lee Chan Sup Shim 2009World Journal of Gastroenterology2009,15,19:12
14Intrahepatic biliary cystadenoma:Is there really an almost exclusively female predominance?显示文摘Biliary cystic tumors,such as cystadenomas and cystadenocarcinomas,are rare cystic tumors of the liver,accounting for less than 5% of all intrahepatic cysts of biliary origin.Biliary cystadenomas have been known to occur predominantly in women (> 85%),and 38%-44% of biliary cystadenocarcinomas have occurred in males.We wrote this letter to comment on a brief article (World J Gasteroenterol 2011 January 21;17(3):361-365) regarding a case of intrahepatic biliary cystic neoplasm treated with surgery.The adenoma-carcinoma sequence is the possible mechanism of carcinogenesis.If the carcinogenesis of biliary cystadenocarcinoma occurs in the adenoma-carcinoma sequence,we believe that the male-to-female ratio of cystadenoma should be higher than the incidence rate that has been reported to date.Ho Hyun Kim Young Hoe Hur Yang Seok Koh Chol Kyoon Cho Jin Woong Kim 2011World Journal of Gastroenterology2011,17,25:12

16The modulation of radiation-induced cell death by genistein in K562 cells:Activation of thymidine kinase 1显示文摘Ionizing radiation is one of the most effective tools in cancer therapy. In a previous study, we reported that protein tyrosine kinase (PTK) inhibitors modulate the radiation responses in the human chronic myelogenous leukemia (CML)cell line K562. The receptor tyrosine kinase inhibitor, genistein, delayed radiation-induced cell death, while non-recepter tyrosine kinase inhibitor, herbimycin A (HMA) enhances radiation-induced apoptosis. In this study, we focused on the modulation of radiation-induced cell death by genistein and performed PCR-select suppression subtractive hybridization(SSH) to understand its molecular mechanism. We identified human thymidine kinase 1 (TK1), which is cell cycle regulatory gene and confirmed expression of TK1 mRNA by Northern blot analysis. Expression of TK1 mRNA and TK 1enzymatic activity were parallel in their increase and decrease. TK1 is involved in G1-S phase transition of cell cycle progression. In cell cycle analysis, we showed that radiation induced G2 arrest in K562 cells but it was not able to sustain. However, the addition of genistein to irradiated cells sustained a prolonged G2 arrest up to 120 h. In addition,the expression of cell cycle-related proteins, cyclin A and cyclin B 1, provided the evidences of G1/S progression and G2-arrest, and their relationship with TK1 in cells treated with radiation and genistein. These results suggest that the activation of TK1 may be critical to modulate the radiation-induced cell death and cell cycle progression in irradiated K562 cells.Min Ho JEONG Young Hee JIN Eun Young KANG Wol Soon JO Hwan Tae PARK Jae Dong LEE Yeo Jin YOO Soo Jin JEONG 2004Cell Research2004,14,4:10
17Gastric leptomeningeal carcinomatosis: Multi-center retrospective analysis of 54 cases显示文摘AIM: To identify the clinical features and outcomes of infrequently reported leptomeningeal carcinomatosis (LMC) of gastric cancer.METHODS: We analyzed 54 cases of cytologically confirmed gastric LMC at four institutions from 1994 to 2007.RESULTS: The male-to-female ratio was 32:22, and the patients ranged in age from 28 to 78 years (median,48.5 years). The majority of patients had advanced disease at initial diagnosis of gastric cancer. The clini-cal or pathologic tumor, node and metastasis stage ofthe primary gastric cancer wasin 38 patients (70%).The median interval from diagnosis of the primarymalignancy to the diagnosis of LMC was 6.3 mo, rang-ing between 0 and 73.1 mo. Of the initial endoscopic f indings for the 45 available patients, 23 (51%) of the patients were Bormann typeand 15 (33%) patientswere Bormann type. Pathologically, 94% of cases proved to be poorly differentiated adenocarcinomas. Signet ring cell component was also observed in 40% of patients. Headache (85%) and nausea/vomiting (58%) were the most common presenting symptoms of LMC. A gadolinium-enhanced magnetic resonance imaging was conducted in 51 patients. Leptomeningeal enhancement was noted in 45 cases (82%). Intrathecal (IT) chemotherapy was administered to 36 patients-primarily methotrexate alone (61%), but also in combi-nation with hydrocortisone/± Ara-C (39%). The median number of IT treatments was 7 (range, 1-18). Concomitant radiotherapy was administered to 18 patients, and concomitant chemotherapy to seven patients. Sev-enteen patients (46%) achieved cytological negative conversion. Median overall survival duration from the diagnosis of LMC was 6.7 wk (95% CI: 4.3-9.1 wk). In the univariate analysis of survival duration, hemoglobin, IT chemotherapy, and cytological negative conversion showed superior survival duration (P = 0.038, P = 0.010, and P = 0.002, respectively). However, in our multivariate analysis, only cytological negative conversion was predictive of relatively longer survival duration (3.6, 6.7 and 14.6 wk, P = 0.030, RR: 0.415, 95% CI: 0.188-0.918).CONCLUSION: Although these patients had a fatal clinical course, cytologic negative conversion by IT chemotherapy may improve survival.Sung Yong Oh Su-Jin Lee Jeeyun Lee Suee Lee Sung-Hyun Kim Hyuk-Chan Kwon Gyeong-Won Lee Jung Hun Kang In Gyu Hwang Joung-Soon Jang Ho Yeong Lim Young Suk Park Won Ki Kang Hyo-Jin Kim 2009World Journal of Gastroenterology2009,15,40:10

19Role of bile acids in colon carcinogenesis显示文摘Bile acids(BAs)are cholesterol derivatives synthesized in the liver and then secreted into the intestine for lipid absorption.There are numerous scientific reports describing BAs,especially secondary BAs,as strong carcinogens or promoters of colon cancers.Firstly,BAs act as strong stimulators of colorectal cancer(CRC)initiation by damaging colonic epithelial cells,and inducing reactive oxygen species production,genomic destabilization,apoptosis resistance,and cancer stem cells-like formation.Consequently,BAs promote CRC progression via multiple mechanisms,including inhibiting apoptosis,enhancing cancer cell proliferation,invasion,and angiogenesis.There are diverse signals involved in the carcinogenesis mechanism of BAs,with a major role of epidermal growth factor receptor,and its down-stream signaling,involving mitogen-activated protein kinase,phosphoinositide 3-kinase/Akt,and nuclear factor kappa-light-chain-enhancer of activated B cells.BAs regulate numerous genes including the human leukocyte antigen class I gene,p53,matrix metalloprotease,urokinase plasminogen activator receptor,Cyclin D1,cyclooxygenase-2,interleukin-8,and miRNAs of CRC cells,leading to CRC promotion.These evidence suggests that targeting BAs is an efficacious strategies for CRC prevention and treatment.Thi Thinh Nguyen Trong Thuan Ung Nam Ho Kim Young Do Jung 2018World Journal of Clinical Cases2018,6,13:10
