| 1 | Factors related to lymph node metastasis and surgical strategy used to treat early gastric carcinoma显示文摘AIM:The prognosis of early gastric carcinoma (EGC) is generally excellent after surgery. The presence or absence of lymph node metastasis in EGC is an important prognostic factor. The survival and recurrence rates of node-negative EGC are much better than those of node-positive EGC. This study examined the factors related to lymph node metastasis in EGC to determine the appropriate treatment for EGC.METHODS: We investigated 748 patients with EGC who underwent surgery between January 1985 and December 1999 at the Division of Gastroenterologic Surgery, Department of Surgery, Chonnam National University Hospital. Several clinicopathologic factors were investigated to analyze their relationship to lymph node metastasis: age, sex, tumor location, tumor size, gross type, histologic type, depth of invasion, extent of lymph node dissection, type of operation,and DNA ploidy.RESULTS:Lymph node metastases were found in 75 patients (10.0%). Univariate analysis showed that male sex, tumor size larger than 2.0cm, submucosal invasion of tumor, histologic differentiation, and DNA ploidy pattern were risk factors for regional lymph node metastasis in EGC patients. However, a multivariate analysis showed that three risk factors were associated with lymph node metastasis:large tumor size, undifferentiated histologic type and submucosal invasion. No statistical relationship was found for age, sex, tumor location, gross type, or DNA ploidy in multivariate analysis. The 5-year survival rate was 94.2% for those without lymph node metastasis and 87.3% for those with lymph node metastasis, and the difference was significant (P<0.05).CONCLUSION: In patients with EGC, the survival rate of patients with positive lymph nodes is significantly worse than that of patients with no lymph node metastasis. Therefore,a standard D2 lymphadenectomy should be performed in patients at high risk of lymph node metastasis: large tumor size, undifferentiated histologic type and submucosal invasion. | Dong Yi Kim Jae Kyoon Joo Seong Yeob Ryu Young Jin Kim Shin Kon Kim | 2004 | World Journal of Gastroenterology2004，10，5： | 68 |
| 2 | Effects of 60 Hz electromagnetic field exposure on testiculargerm cell apoptosis in mice显示文摘Aim:To evaluate the effects of 60 Hz extremely low frequency (ELF) elelctromagnetic field (EMF) exposure on germ cell apoptosis in the testis of mice.Methods:Adult male BALB/c mice (7 weeks of age) were exposed to a 60 Hz EMF of 0.1 mT or 0.5 mT for 24 h/day.A sham-exposed group served as the control.After 8 weeks of exposure,the mice were sacrificed.Germ cell apoptosis in the testis was assessed by histopathological examination,the terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling assay (TUNEL) and flow cytometric examination of isolated spermatogenic cells stained with 7 aminoactinomycin D (7-AAD).Results:EMF exposure did not significantly affect the body and testis weights,but significantly increased the incidence of germ cell death.The distinguishing morphological feature of EMF exposure was a decrement in the number of well organized seminiferous tubules.Quantitative analysis of TUNEL-positive germ cells showed a significantly higher apoptotic rate in the 0.5 mT exposed mice than that in the sham controls (P<0.05),while the difference between the two exposed groups was insignificant.The TUNEL-positive cells were mainly spermatogonia.In flow cytometryanalysis,the percentage of live cells [forward scatter count (FSC)^hgh7-AAD-] was lower in the exposed groups than that in the controls (Figure 5A),but the decrease in viability was not statistically significant.Conclusion:Continuousexposure to ELF EMF may induce testicular germ cell apoptosis in mice.(Asian J Androl 2004 Mar;6:29-34) | Jin Sang Lee Sang Seok Ahn Kyeong Cheon Jung Yoon-Won Kim Sang Kon Lee | 2004 | Asian Journal of Andrology2004，6，1： | 23 |

| 4 | Biliary drainage for obstructive jaundice caused by unresectable hepatocellular carcinoma: the endoscopic versus percutaneous approach显示文摘BACKGROUND: For palliative treatment of the obstructive jaundice associated with unresectable hepatocellular carcinoma (HCC), percutaneous transhepatic biliary drainage (PTBD) or endoscopic retrograde biliary drainage (ERBD) has been performed. PTBD is preferred as an initial procedure. Little is known about the better option for patients with obstructive jaundice caused by unresectable HCC. METHODS: Sixty patients who had received ERBD or PTBD for the palliative treatment of obstructive jaundice caused by unresectable HCC between January 2006 and May 2010 were included in this retrospective study. Successful drainage, drainage patency, and the overall survival of patients were evaluated. RESULTS: Univariate analysis revealed that the overall frequency of successful drainage was higher in the ERBD group (22/29, 75.9%) than in the PTBD group (15/31, 48.4%) (P=0.029); but multivariate analysis showed marginal significance (P=0.057). The duration of drainage patency was longer in the ERBD group than in the PTBD group (82 vs 37 days, respectively, P=0.020). Regardless of what procedure was performed, the median survival time of patients who had a successful drainage was much longer than that of the patients who did not have a successful drainage (143 vs 38 days, respectively, P<0.001).CONCLUSION: Besides PTBD, ERBD may be used as the initial treatment option to improve obstructive jaundice in patients with unresectable HCC if there is a longer duration of drainage patency after a successful drainage. | Jongkyoung Choi Ji Kon Ryu Sang Hyub Lee Dong-Won Ahn Jin-Hyeok Hwang Yong-Tae Kim Yong Bum Yoon Joon Koo Han | 2012 | Hepatobiliary & Pancreatic Diseases International2012，11，6： | 17 |
| 5 | Optimal biliary drainage for inoperable Klatskin's tumor based on Bismuth type显示文摘AIM: To investigate differences in the effects of biliary drainage procedures in patients with inoperable Klatskin’s tumor based on Bismuth type, considering endoscopic retrograde biliary drainage (ERBD), external percutaneous transhepatic biliary drainage (EPTBD) and internal biliary stenting via the PTBD tract (IPTBD). METHODS: The initial success rate, cumulative patency rate, and complication rate were compared retrospectively, according to the Bismuth type and ERBD, EPTBD, and IPTBD. Patency was defined as the duration for adequate initial bile drainage or to the point of the patient’s death associated with inadequate drainage. RESULTS: One hundred thirty-four patients (93 men, 41 women; 21 Bismuth type Ⅱ, 47 Ⅲ, 66 Ⅳ; 34 ERBD, 66 EPTBD, 34 IPTBD) were recruited. There were no differences in demographics among the groups. Adequate initial relief of jaundice was achieved in 91% of patients without a significant difference in the results among different procedures or Bismuth types. The cumulative patency rates for ERBD and IPTBD were better than those for EPTBD with Bismuth type Ⅲ. IPTBD provided an excellent response for Bismuth type Ⅳ. However, there was no difference in the patency rate among drainage procedures for Bismuth type Ⅱ. Procedure-related cholangitis occurred less frequently with EPTBD than with ERBD and IPTBD. CONCLUSION: ERBD is recommended as the first- line drainage procedure for the palliation of jaundice in patients with inoperable Klatskin’s tumor of Bismuth type Ⅱ or Ⅲ, but IPTBD is the best option for Bismuth type Ⅳ. | Sang Hyub Lee Joo Kyung Park Won Jae Yoon Jun Kyu Lee Ji Kon Ryu Yong Bum Yoon Yong-Tae Kim | 2007 | World Journal of Gastroenterology2007，13，29： | 17 |
| 6 | Clinical and pathological differences between serum immunoglobulin G4-positive and -negative type 1 autoimmune pancreatitis显示文摘AIM: To identify clinical and pathological differences between serum immunoglobulin G4 (IgG4)-positive (SIP) and IgG4-negative (SIN) type 1 autoimmune pancreatitis (AIP) in South Korea. METHODS: AIP was diagnosed by the international consensus diagnostic criteria. The medical records and pathology were retrospectively reviewed and IgG4-positive cells were counted in a high power field (HPF). Type I AIP was defined as a high serum level of IgG4or histological finding. SIN type 1 AIP was defined as a histological evidence of type 1 AIP and a normal serum IgG4 level. The clinical and pathological findings were compared between the two groups. The analysis was performed using Student's t test, Fischer's exact test and Mann-Whitney's U test. A P value of < 0.05 was considered statistically significant. As repeated com- parison was made, P values of less than 5% (P < 0.05) were considered significant. RESULTS: Twenty five patients with definite type 1 AIP (19 histologically and six serologically diagnosed cases) were enrolled. The mean tissue IgG4 concentrations were significantly higher in SIP than SIN group (40 cells per HPF vs 18 cells per HPF, P = 0.02). Among eight SIN patients, the tissue IgG4 concentrations were less than 15 cells per HPF in most of cases, except one. The sensitivity of serum IgG4 was 68% (17 SIP and eight SIN AIP). Other organ involvement was more frequent- ly associated with SIP than SIN AIP (59% vs 26%, P = 0.016). However, the relapse rate and diffuse swelling of the pancreas were not associated with serum IgG4 level. The concentrations of IgG4-positive cells per HPF were higher in SIP than SIN AIP (40 vs 18, P = 0.02). CONCLUSION: The sensitivity of serum IgG4 was 68% in type 1 AIP. High serum IgG4 level was associated with other organ involvement and tissue IgG4 concentration but did not affect the relapse rate in type 1 AIP. | Woo Hyun Paik Ji Kon Ryu Jin Myung Park Byeong Jun Song Joo Kyung Park Yong-Tae Kim Kyoungbun Lee | 2013 | World Journal of Gastroenterology2013，19，25： | 16 |
| 7 | Distinction of white,beige and brown adipocytes derived from mesenchymal stem cells显示文摘Adipose tissue is a major metabolic organ, and it has been traditionally classified as either white adipose tissue(WAT) or brown adipose tissue(BAT). WAT and BAT are characterized by different anatomical locations, morphological structures, functions, and regulations. WAT and BAT are both involved in energy balance. WAT is mainly involved in the storage and mobilization of energy in the form of triglycerides, whereas BAT specializes in dissipating energy as heat during cold- or diet-induced thermogenesis. Recently, brownlike adipocytes were discovered in WAT. These brownlike adipocytes that appear in WAT are called beige or brite adipocytes. Interestingly, these beige/brite cells resemble white fat cells in the basal state, but they respond to thermogenic stimuli with increased levels of thermogenic genes and increased respiration rates. In addition, beige/brite cells have a gene expressionpattern distinct from that of either white or brown fat cells. The current epidemic of obesity has increased the interest in studying adipocyte formation(adipogenesis), especially in beige/brite cells. This review summarizes the developmental process of adipose tissues that originate from the mesenchymal stem cells and the features of these three different types of adipocytes. | Anna Park Won Kon Kim Kwang-Hee Bae | 2014 | World Journal of Stem Cells2014，6，1： | 15 |
| 8 | 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 |
| 9 | Ratio of mean platelet volume to platelet count is a potential surrogate marker predicting liver cirrhosis显示文摘AIM To provide a simple surrogate marker predictive of liver cirrhosis(LC).METHODS Specimens from 302 patients who underwent resection for hepatocellular carcinoma between January 2006 and December 2012 were retrospectively analyzed. Based on pathologic findings, patients were divided into groups based on whether or not they had LC. Parameters associated with hepatic functional reserve were compared in these two groups using MannWhitney U-test for univariate analysis. Factors differing significantly in univariate analyses were entered into multivariate logistic regression analysis.RESULTS There were significant differences between the LC group(n = 100) and non-LC group(n = 202) in prothrombin activity, concentrations of alanine aminotransferase, aspartate aminotransferase, total bilirubin, albumin, cholinesterase, type Ⅳ collagen, hyaluronic acid, indocyanine green retention rate at 15 min, maximal removal rate of technitium-99 m diethylene triamine pentaacetic acid-galactosyl human serum albumin and ratio of mean platelet volume to platelet count(MPV/PLT). Multivariate analysis showed that prothrombin activity, concentrations of alanine aminotransferase, aspartate aminotransferase, total bilirubin and hyaluronic acid, and MPV/PLT ratio were factors independently predictive of LC. The area under the curve value for MPV/PLT was 0.78,with a 0.8 cutoff value having a sensitivity of 65% and a specificity of 78%.CONCLUSION The MPV/PLT ratio, which can be determined simply from the complete blood count, may be a simple surrogate marker predicting LC. | Hiroya Iida Masaki Kaibori Kosuke Matsui Morihiko Ishizaki Masanori Kon | 2018 | World Journal of Hepatology2018，10，1： | 14 |

| 11 | Risk factors of organ failure in cholangitis with bacteriobilia显示文摘AIM: To identify the risk factors for organ failure(OF) in cholangitis with bacteriobilia.METHODS: This study included 182 patients with acute cholangitis who underwent percutaneous transhepatic biliary drainage between January 2005 and April 2013. We conducted a retrospective analysis of comprehensive clinical and laboratory data.RESULTS: There were 24 cases(13.2%) of OF and five deaths(2.7%). Bile culture was positive for microbial growth in 130 out of 138(94.2%) patients. In multivariate analysis of 130 patients with positivebile cultures, significant predictive factors for OF were the presence of extended-spectrum beta-lactamase(ESBL) organisms in blood cultures, pre-existing renal dysfunction, and choledocholithiasis as an etiology, with odds ratios of 15.376, 6.319, and 3.573, respectively. We developed a scoring system with a regression coefficient of each significant variable. The OF score was calculated using the following equation:(2.7 × ESBL organisms in blood cultures) +(1.8 × pre-existing renal dysfunction) +(1.3 × choledocholithiasis). This scoring system for predicting OF was highly specific(99.1%) and had a positive predictive value of 86.2%.CONCLUSION: ESBL organisms in blood cultures, preexisting renal dysfunction, and choledocholithiasis are risk factors for OF in cholangitis with bacteriobilia. The OF scoring system may aid clinicians to identify a poor prognosis group. | Jae Min Lee Sang Hyub Lee Kwang Hyun Chung Jin Myung Park Ban Seok Lee Woo Hyun Paik Joo Kyung Park Ji Kon Ryu Yong-Tae Kim | 2015 | World Journal of Gastroenterology2015，21，24： | 8 |
| 12 | Non-surgical treatment of post-surgical bile duct injury: Clinical implications and outcomes显示文摘AIM:To investigate the prognostic factors determining the success rate of non-surgical treatment in the management of post-operative bile duct injuries(BDIs).METHODS:The study patients were enrolled from the pancreatobiliary units of a tertiary teaching hospital for the treatment of BDIs after hepatobiliary tract surgeries,excluding operations for liver transplantation andmalignancies,from January 1999 to August 2010.A total of 5167 patients underwent operations,and 77patients had BDIs following surgery.The primary end point was the treatment success rate according to different types of BDIs sustained using endoscopic or percutaneous hepatic approaches.The type of BDI was defined using one of the following diagnostic tools:endoscopic retrograde cholangiography,percutaneous transhepatic cholangiography,computed tomography scan,and magnetic resonance cholangiography.Patients with a final diagnosis of BDI underwent endoscopic and/or percutaneous interventions for the treatment of bile leak and/or stricture if clinically indicated.Patient consent was obtained,and study approval was granted by the Institutional Review Board in accordance with the legal regulations of the Human Clinical Research Center at the Seoul National University Hospital in Seoul,South Korea.RESULTS:A total of 77 patients were enrolled in the study.They were divided into three groups according to type of BDI.Among them,55 patients(71%)underwent cholecystectomy.Thirty-six patients(47%)had bile leak only(type 1),31 patients had biliary stricture only(type 2),and 10 patients had both bile leak and biliary stricture(type 3).Their initial treatment modalities were non-surgical.The success rate of non-surgical treatment in each group was as follows:BDI type 1:94%;type 2:71%;and type 3:30%.Clinical parameters such as demographic factors,primary disease,operation method,type of operation,non-surgical treatment modalities,endoscopic procedure steps,type of BDI,time to diagnosis and treatment duration were evaluated to evaluate the prognostic factors affecting the success rate.The type of BDI was a statistically significant prognostic factor in determining the success rate of non-surgical treatment.In addition,a shorter time to diagnosis of BDI after the operation correlated significantly with higher success rates in the treatment of type 1 BDIs.CONCLUSION:Endoscopic or percutaneous hepatic approaches can be used as an initial treatment in type1 and 2 BDIs.However,surgical intervention is a treatment of choice in type 3 BDI. | Young Ook Eum Joo Kyung Park Jaeyoung Chun Sang-Hyub Lee Ji Kon Ryu Yong-Tae Kim Yong-Bum Yoon Chang Jin Yoon Ho-Seong Han Jin-Hyeok Hwang | 2014 | World Journal of Gastroenterology2014，20，22： | 7 |
| 13 | Endoscopic management of occluded metal biliary stents:Metal versus 10F plastic stents显示文摘AIM:To compare the efficacy of self-expandable metal stents(SEMSs) with 10F plastic stents(PSs) in the endoscopic management of occluded SEMSs.METHODS:We retrospectively reviewed the medical records of 56 patients who underwent SEMS insertion for palliation of unresectable malignant biliary obstruction between 2000 and 2007 and subsequent endoscopic retrograde biliary drainage(ERBD) with SEMS or PS for initial SEMS occlusion between 2000 and 2008.RESULTS:Subsequent ERBD with SEMS was performed in 29 patients and with PS in 27.The median time to stent occlusion after subsequent ERBD was 186 d in the SEMS group and 101 d in the PS group(P= 0.118).Overall median stent patency was 79 d for the SEMS group and 66 d for the PS group(P = 0.379).The mean number of additional biliary drainage procedures after subsequent ERBD in patients that died(n = 50) during the study period was 2.54 ± 4.12 for the SEMS group and 1.85 ± 1.95 for the PS group(P = 0.457).The mean total cost of additional biliary drainage procedures after the occlusion of subsequent SEMS or PS was $410.04 ± 692.60 for the SEMS group and $630.16 ± 671.63 for the PS group(P = 0.260).Tumor ingrowth as the cause of initial SEMS occlusion was the only factor associated with a shorter time to subsequent stent occlusion(101 d for patients with tumor ingrowth vs 268 d for patients without tumor ingrowth,P = 0.008).CONCLUSION:Subsequent ERBD with PSs offered similar patency and number of additional biliary drainage procedures compared to SEMSs in the management of occluded SEMS. | Won Jae Yoon Ji Kon Ryu Jung Won Lee Dong-Won Ahn Yong-Tae Kim Yong Bum Yoon Sang Myung Woo Woo Jin Lee | 2010 | World Journal of Gastroenterology2010，16，42： | 7 |
| 14 | Viral hepatitis prevalence in patients with active and latent tuberculosis显示文摘AIM: To assess the prevalence of hepatitis B virus(HBV) and hepatitis C virus(HCV) infection and association with drug induced liver injury(DILI) in patients undergoing anti-tuberculosis(TB) therapy.METHODS: Four hundred and twenty nine patients with newly diagnosed TB- either active disease or latent infection- who were due to commence antiTB therapy between September 2008 and May 2011 were included. These patients were prospectively tested for serological markers of HBV, HCV and human immunodeficiency virus(HIV) infections- hepatitis B core antigen(HBc Ag), hepatitis B surface antigen(HBs Ag), hepatitis B e antigen, Ig G and Ig M antibody to HBc Ag(anti-HBc), HCV Ig G antibody and HIV antibody using a combination of enzyme-linked immunosorbent assay, Western blot assay and polymerase chain reaction techniques. Patients were reviewed at least monthly during the TB treatment initiation phase. Liver function tests were measured prior to commencement of antiTB therapy and 2-4 wk later. Liver function tests were also performed at any time the patient had significant nausea, vomiting, rash, or felt non-specifically unwell. Fisher's exact test was used to measure significance in comparisons of proportions between groups. A P value of less than 0.05 was considered statistically significant.RESULTS: Of the 429 patients, 270(62.9%) had active TB disease and 159(37.1%) had latent TB infection. 61(14.2%) patients had isolated anti-HBc positivity, 11(2.6%) were also HBs Ag positive and 7(1.6%) were HCV-antibody positive. 16/270 patients with active TB disease compared to 2/159 patients with latent TB infection had markers of chronic viral hepatitis(HBs Ag or HCV antibody positive; P = 0.023). Similarly the proportion of HBs Ag positive patients were significantly greater in the active vs latent TB infection group(10/43 vs 1/29, P = 0.04). The prevalence of chronic HBV or HCV was significantly higher than the estimated United Kingdom prevalence of 0.3% for each. We found no association between DILI and presence of serological markers of HBV or HCV. Three(5.3%) patients with serological markers of HBV or HCV infection had DILI compared to 25(9.5%) patients without; P = 0.04.CONCLUSION: Viral hepatitis screening should be considered in TB patients. DILI risk was not increased in patients with HBV/HCV. | Hesam Ahmadi Nooredinvand David W Connell Mahmoud Asgheddi Mohammed Abdullah Marie O'Donoghue Louise Campbell Melissa I Wickremasinghe Ajit Lalvani Onn Min Kon Shahid A Khan | 2015 | World Journal of Gastroenterology2015，21，29： | 7 |
| 15 | Safety of endoscopic ultrasound-guided ethanol ablation for pancreatic cystic lesions: A single-center experience of 214 patients显示文摘Background:Endoscopic ultrasound-guided ethanol ablation(EUS-EA)for pancreatic cystic lesions(PCLs)has been used in recent years as a feasible treatment modality for low malignant probability PCLs or patients considered high-risk for surgery.The present study aimed to confirm the safety of EUS-EA and to find predictive factors for adverse event(AE).Methods:A retrospective review was performed from the prospectively maintained database of patients who underwent EUS-EA for PCLs from June 2006 to April 2018 at Seoul National University Hospital.The primary outcomes of the study were the rates of AEs and severe AEs by EUS-EA.The secondary outcome was the predictive factors of AEs including acute pancreatitis and abdominal pain.Results:A total of 214 patients were evaluated and the diagnoses of PCLs according to cystic fluid analysis and clinical features were as follows:serous cystic neoplasm(32.2%),mucinous cystic neoplasm(26.6%),branch duct type intraductal papillary mucinous neoplasm(BD-IPMN)(29.4%),and pseudocyst(11.7%).Three patients(1.4%)experienced severe AEs.Overall,AEs occurred in 71(33.2%)patients.BD-IPMN(OR:2.87;95%CI:1.05–7.84;P=0.040),multilocular cysts(OR:3.59;95%CI:1.09–11.85;P=0.036),suspected ethanol leakage during procedure(OR:10.68;95%CI:1.98–57.53;P=0.006),and sticky cystic fluid(OR:3.83;95%CI:1.20–12.24;P=0.024)were predictive factors for post-procedural acute pancreatitis.PCLs of uncinate process(OR:2.99;95%CI:1.22–7.35;P=0.017)and PCLs with exophytic portion(OR:3.70;95%CI:1.96–7.01;P<0.001)were predictive factors for post-procedural abdominal pain.Conclusions:EUS-EA is a safe procedure with a very low rate of severe AEs.It seems possible to predict the AEs according to the features of the procedure and PCLs. | Jin Ho Choi Sang Hyub Lee Young Hoon Choi Min Su You Bang-Sup Shin Woo Hyun Paik Ji Kon Ryu Yong-Tae Kim | 2019 | Hepatobiliary & Pancreatic Diseases International2019，18，6： | 6 |
| 16 | Metastasis to the gallbladder:A single-center experience of 20 cases in South Korea显示文摘AIM:To evaluate the clinicopathologic characteristics of patients with metastases to the gallbladder (MGBs).METHODS: We performed a single-center retrospective study of 20 patients with MGBs diagnosed pathologically from 1999 to 2007.RESULTS: Among 417 gallbladder (GB) malignancies, 20 (4.8%) were MGBs. The primary malignancies originated from the stomach (n=8), colorectum (n=3), liver (n=2), kidney (n=2), skin (n=2), extrahepatic bile duct (n=1), uterine cervix (n=1), and appendix (n=1). Twelve patients were diagnosed metachronously, presenting with cholecystitis (n=4), abdominal pain (n=2), jaundice (n=1), weight loss (n=1), and serum CA 19-9 elevation (n=1); five patients were asymptomatic. The median survival after the diagnosis of MGB was 8.7 mo. On Cox regression analysis, R0 resection was the only factor associated with a prolonged survival [hazard ratio (HR):0.01,P =0.002]; presentation with cholecystitis was associated with poor survival (HR:463.27, P=0.006).CONCLUSION: MGBs accounted for 4.8% of all pathologically diagnosed GB malignancies.

| 17 | Effects of insulin and pathway inhibitors on the PI3K-Akt- mTOR phosphorylation profile in acute myeloid leukemia cells显示文摘The phosphatidylinositol 3-kinase(PI3K)-Akt-mechanistic target of rapamycin(mTOR)pathway is constitutively activated in human acute myeloid leukemia(AML)cells and is regarded as a possible therapeutic target.Insulin is an agonist of this pathway and a growth factor for AML cells.We characterized the effect of insulin on the phosphorylation of 10 mediators in the main track of the PI3K-Akt-mTOR pathway in AML cells from 76 consecutive patients.The overall results showed that insulin significantly increased the phosphorylation of all investigated mediators.However,insulin effects on the pathway activation profile varied among patients,and increased phosphorylation in all mediators was observed only in a minority of patients;in other patients,insulin had divergent effects.Global gene expression profiling and proteomic/phosphoproteomic comparisons suggested that AML cells from these two patient subsets differed with regard to AML cell differentiation,transcriptional regulation,RNA metabolism,and cellular metabolism.Strong insulin-induced phosphorylation was associated with weakened antiproliferative effects of metabolic inhibitors.PI3K,Akt,and mTOR inhibitors also caused divergent effects on the overall pathway phosphorylation profile in the presence of insulin,although PI3K and Akt inhibition caused a general reduction in Akt pT308 and 4EBP1 pT36/pT45 phosphorylation.For Akt inhibition,the phosphorylation of upstream mediators was generally increased or unaltered.In contrast,mTOR inhibition reduced mTOR pS2448 and S6 pS244 phosphorylation but increased Akt pT308 phosphorylation.In conclusion,the effects of both insulin and PI3K-Akt-mTOR inhibitors differ between AML patient subsets,and differences in insulin responsiveness are associated with differential susceptibility to metabolic targeting. | Ina Nepstad Kimberley Joanne Hatfield Ida Sofie Grønningsæter Elise Aasebø Maria Hernandez-Valladares Karen Marie Hagen Kristin Paulsen Rye Frode SBerven Frode Selheim Håkon Reikvam Øystein Bruserud | 2019 | Signal Transduction and Targeted Therapy2019，4，1： | 4 |

| 19 | Clobenpropit enhances anti-tumor effect of gemcitabine in pancreatic cancer显示文摘AIM:To evaluate the anti-tumor effect of clobenpropit,which is a specific H3 antagonist and H4 agonist,in combination with gemcitabine in a pancreatic cancer cell line.METHODS:Three kinds of human pancreatic cancer cell lines(Panc-1,MiaPaCa-2,and AsPC-1)were used in this study.Expression of H3 and H4 receptors in pancreatic cancer cells was identified with Western blotting.Effects of clobenpropit on cell proliferation,migration and apoptosis were evaluated.Alteration of epithelial and mesenchymal markers after administration of clobenpropit was analyzed.An in vivo study with a Panc-1xenograft mouse model was also performed.RESULTS:H4 receptors were present as 2 subunits in human pancreatic cancer cells,while there was no expression of H3 receptor.Clobenpropit inhibited cell migration and increased apoptosis of pancreatic cancer cells in combination with gemcitabine.Clobenpropit up-regulated E-cadherin,but down-regulated vimentin and matrix metalloproteinase 9 in real-time polymerase chain reaction.Also,clobenpropit inhibited tumor growth(gemcitabine 294±46 mg vs combination 154±54 mg,P=0.02)and enhanced apoptosis in combination with gemcitabine(control 2.5%,gemcitabine25.8%,clobenpropit 9.7%and combination 40.9%,P=0.001)by up-regulation of E-cadherin and downregulation of Zeb1 in Panc-1 xenograft mouse.CONCLUSION:Clobenpropit enhanced the anti-tumor effect of gemcitabine in pancreatic cancer cells through inhibition of the epithelial-mesenchymal transition process. | Woo Hyun Paik Ji Kon Ryu Kyoung-Sin Jeong Jin Myung Park Byeong Jun Song Sang Hyub Lee Yong-Tae Kim Yong Bum Yoon | 2014 | World Journal of Gastroenterology2014，20，26： | 4 |
| 20 | A left-sided periappendiceal abscess in an adult with intestinal malrotation显示文摘Left-sided periappendiceal abscesses occur in association with two types of congenital anomaly: intestinal malrotation and situs inversus. It is diffi cult to obtain an accurate preoperative diagnosis of these abscesses due to the abnormal position of the appendix. We present an unusual case of a left-sided periappendiceal abscess in an adult with intestinal malrotation, the diagnosis of which was a challenge. | Min Ro Lee Jong Hun Kim Yong Hwang Young Kon Kim | 2006 | World Journal of Gastroenterology2006，12，33： | 4 |
