| 1 | Small 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 | 2009 | World Journal of Gastroenterology2009，15，34： | 34 |

| 4 | The 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 | 2018 | Journal of Animal Science and Biotechnology2018，9，4： | 16 |
| 5 | Gender 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 | 2017 | World Journal of Gastroenterology2017，23，45： | 16 |

| 7 | Prevalence 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 | 2009 | World Journal of Gastroenterology2009，15，1： | 15 |
| 8 | Characteristics of gastric cancer in peptic ulcer patients with Helicobacter pylori infection显示文摘AIM:To evaluate the incidence and clinical characteristics of gastric cancer(GC) in peptic ulcer patients with Helicobacter pylori(H.pylori) infection.METHODS:Between January 2003 and December 2013, the medical records of patients diagnosed with GC were retrospectively reviewed.Those with previous gastric ulcer(GU) and H.pylori infection were assigned to the Hp GU-GC group(n = 86) and those with previous duodenal ulcer(DU) disease and H.pylori infection were assigned to the Hp DUGC group(n = 35).The incidence rates of GC in the Hp GU-GC and Hp DU-GC groups were analyzed.Data on demographics(age, gender, peptic ulcer complications and cancer treatment), GC clinical characteristics [location, pathological diagnosis, differentiation, T stage, Lauren's classification, atrophy of surrounding mucosa and intestinal metaplasia(IM)], outcome of eradication therapy for H.pylori infection, esophagogastroduodenoscopy number and the duration until GC onset were reviewed.Univariate and multivariate analyses were performed to identify factors influencing GC development.The relative risk of GC was evaluated using a Cox proportional hazards model.RESULTS:The incidence rates of GC were 3.60%(86/2387) in the Hp GU-GC group and 1.66%(35/2098) in the Hp DU-GC group.The annual incidence was 0.41% in the Hp GU-GC group and 0.11% in the Hp DUGC group.The rates of moderate-to-severe atrophy of the surrounding mucosa and IM were higher in the Hp GU-GC group than in the Hp DU-GC group(86% vs 34.3%, respectively, and 61.6% vs 14.3%, respectively, P < 0.05).In the univariate analysis, atrophy of surrounding mucosa, IM and eradication therapy for H.pylori infection were significantly associated with the development of GC(P < 0.05).There was no significant difference in the prognosis of GC patients between the Hp GU-GC and Hp DU-GC groups(P = 0.347).The relative risk of GC development in the Hp GUGC group compared to that of the Hp DU-GC group,after correction for age and gender,was 1.71(95%CI:1.09-2.70;P=0.02).CONCLUSION:GU patients with H.pylori infection had higher GC incidence rates and relative risks.Atrophy of surrounding mucosa,IM and eradication therapy were associated with GC. | Jae Jin Hwang Dong Ho Lee Ae-Ra Lee Hyuk Yoon Cheol Min Shin Young Soo Park Nayoung Kim | 2015 | World Journal of Gastroenterology2015，21，16： | 15 |
| 9 | Endoscopic 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 | 2009 | World Journal of Gastroenterology2009，15，19： | 12 |

| 11 | The 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 | 2004 | Cell Research2004，14，4： | 10 |
| 12 | Gastric 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 | 2009 | World Journal of Gastroenterology2009，15，40： | 10 |

| 17 | Collision tumor of hepatocellular carcinoma and neuroendocrine carcinoma involving the liver: Case report and review of the literature显示文摘Primary hepatic neuroendocrine carcinoma(NEC) with concurrent occurrence of hepatocellular carcinoma(HCC) of the liver is very rare. Only 8 cases have been reported in the literature. Concurrent occurrence of HCC and NEC in the liver is classified as combined type or collision type by histological distributional patterns; only 2 cases have been reported. Herein, we report a case of collision type concurrent occurrence of HCC and NEC, in which primary hepatic NEC was in only a small portion of the nodule, which is different from the 2 previously reported cases. A 72-year-old male with chronic hepatitis C was admitted to our hospital for a hepatic mass detected by liver computed tomography(CT) at another clinic. Because the nodule was in hepatic segment 3 and had proper radiologic findings for diagnosis of HCC, including enhancement in the arterial phase and wash-out in the portal and delay phases, the patient was treated with laparoscopic left lateral sectionectomy. The pathology demonstrated that the nodule was 2.5 cm and was moderately differentiated HCC. However, a 3 mm-sized focal neuroendocrine carcinoma was also detected on the capsule of the nodule. The tumor was concluded to be a collision type with HCC and primary hepatic NEC. After the surgery, for follow-up, the patient underwent a liver CT every 3 mo. Five multiple nodules were found in the right hepatic lobe on the follow-up liver CT 6 mo post-operatively. As the features of the nodules in the liver CT and MRI were different from that of HCC, a liver biopsy was performed. Intrahepatic recurrent NEC was proven after the liver biopsy, which showed the same pathologic features with the specimen obtained 6 mo ago. Palliative chemotherapy with a combination of etoposide and cisplatin has been administered for 4 months, showing partial response. | Gyu Ho Choi Sun Young Ann Soon Il Lee Suk BaeKim Il Han Song | 2016 | World Journal of Gastroenterology2016，22，41： | 8 |
