1Expression of heat shock proteins (HSP27, HSP60, HSP70, HSP90, GRP78, GRP94) in hepatitis B virus-related hepatocellular carcinomas and dysplastic nodules显示文摘AIM: Expression of heat shock proteins (HSPs) is frequently up-regulated in hepatocellular carcinoma (HCC), which evolves from dysplastic nodule (DN) and early HCC to advanced HCC. However, little is known about the differential expression of HSPs in multistep hepatocarcinogenesis. It was the purpose of this study to monitor the expression of HSPs in multistep hepatocarcinogenesis and to evaluate their prognostic significance in hepatitis B virus (HBV)related HCC.METHODS: Thirty-eight HCC and 19 DN samples were obtained from 52 hepatitis B surface antigen-positive Korean patients. Immunohistochemical and dot immunoblot analyses of HSP27, HSP60, HSP70, HSP90, glucoseregulated protein (GRP)78, and GRP94 were performed and their expression at different stages of HCC development was statistically analyzed.RESULTS: Expression of HSP27, HSP70, HSP90, GRP78, and GRP94 increased along with the stepwise progression of hepatocarcinogenesis. Strong correlation was found only in GRP78 (Spearman's r= 0.802). There was a positive correlation between the expressions of GRP78, GRP94, HSP90, or HSP70 and prognostic factors of HCC. Specifically, the expression of GRP78, GRP94, or HSP90 was associated significantly with vascular invasion and intrahepatic metastasis.CONCLUSION: The expressions of HSPs are commonly up-regulated in HBV-related HCCs and GRP78 might play an important role in the stepwise progression of HBVrelated hepatocarcinogenesis. GRP78, GRP94, and HSP90 may be important prognostic markers of HBV-related HCC, strongly suggesting vascular invasion and intrahepatic metastasis.Seung Oe Lim Sung Gyoo Park Jun-Hi Yoo Young Min Park Hie-Joon Kim Kee-Taek Jang Jae Won Cho Byung Chul Yoo Gu-Hung Jung Cheol Keun Park 2005World Journal of Gastroenterology2005,11,14:62
2Diagnostic criteria for autoimmune chronic pancreatitis revisited显示文摘自体免疫的慢性胰炎(AIP ) 逐渐地正在是广泛地认出了世界,,这个实体的知识积聚。首先, AIP 以它对与平常的慢性胰炎相对照的口头的类固醇治疗的戏剧的反应是到临床医生的很吸引人的疾病。尽管 AIP 的许多典型调查结果被描述了,明确的诊断标准充分没被建立。在一年 2002,日本胰社会在全世界出版了 AIP 和许多临床医生的诊断标准为 AIP 的诊断使用这些标准。然而,日本胰社会建议的诊断标准不是完全令人满意的,一些组在报导 AIP 使用他们的自己的标准。这评论为这个逐渐地公认的条件讨论当前的诊断标准的几潜在的限制。手稿被组织强调对召开一致发展的需要改进了诊断标准。Kyu-Pyo Kim Myung-Hwan Kim Jong Cheol Kim Sang Soo Lee Dong Wan Seo Sung Koo Lee 2006World Journal of Gastroenterology2006,12,16:73
3Clinical features and prognosis of patients with extrahepatic metastases from hepatocellular carcinoma显示文摘AIM: To assess the clinical features and prognosis of 151 patients with extrahepatic metastases from primary hepatocellular carcinoma (HCC), and describe the treatment strategy for such patients. METHODS: After the diagnosis of HCC, all 995 consecutive HCC patients were followed up at regular intervals and 151 (15.2%) patients were found to have extrahepatic metastases at the initial diagnosis of primary HCC or developed such tumors during the follow-up period. We assessed their clinical features, prognosis, and treatment strategies. RESULTS: The most frequent site of extrahepatic metastases was the lungs (47%), followed by lymph nodes (45%), bones (37%), and adrenal glands (12%). The cumulative survival rates after the initial diagnosis of extrahepatic metastases at 6, 12, 24, and 36 mo were 44.1%, 21.7%, 14.2%, 7.1%, respectively. The median survival time was 4.9 mo (range, 0-37 mo). Fourteen patients (11%) died of extrahepatic HCC, others died of primary HCC or liver failure. CONCLUSION: The prognosis of HCC patients with extrahepatic metastases is poor. With regard to the cause of death, many patients would die of intrahepatic HCC and few of extrahepatic metastases. Although most of HCC patients with extrahepatic metastases should undergo treatment for the primary HCC mainly, treatment of extrahepatic metastases in selected HCC patients who have good hepatic reserve, intrahepatictumor stage (T0-T2), and are free of portal venous invasion may improve survival.Kiminori Uka Hiroshi Aikata Shintaro Takaki Hiroo Shirakawa Soo Cheol Jeong Keitaro Yamashina Akira Hiramatsu Hideaki Kodama Shoichi Takahashi Kazuaki Chayama 2007World Journal of Gastroenterology2007,13,3:44
4Clinicopathologic factors and molecular markers related to lymph node metastasis in early gastric cancer显示文摘AIM: To analyze predictive factors for lymph node metastasis in early gastric cancer.METHODS: We analyzed 1104 patients with early gastric cancer(EGC) who underwent a gastrectomy with lymph-node dissection from May 2003 through July 2011. The clinicopathologic factors and molecular markers were assessed as predictors for lymph node metastasis. Molecular markers such as microsatellite instability, human mut L homolog 1, p53, epidermal growth factor receptor(EGFR) and human epidermal growth factor receptor 2(HER2) were included. The χ2 test and logistic regression analysis were used to determine clinicopathologic parameters.RESULTS: Lymph node metastasis was observed in 104(9.4%) of 1104 patients. Among 104 cases of lymph node positive patients, 24 patients(3.8%) were mucosal cancers and 80 patients(16.7%) were submucosal. According to histologic evaluation, the number of lymph node metastasis found was 4(1.7%) for well differentiated tubular adenocarcinoma, 45(11.3%) for moderately differentiated tubular adenocarcinoma, 36(14.8%) for poorly differentiated tubular adenocarcinoma, and 19(8.4%) for signet ring cell carcinoma. Of 690 EGC cases, 77 cases(11.2%) showed EGFR overexpression. HER2 overexpression was present in 110 cases(27.1%) of 406 EGC patients. With multivariate analysis, female gender(OR = 2.281, P = 0.009), presence of lymphovascular invasion(OR = 10.950, P < 0.0001), diameter(≥ 20 mm, OR = 3.173, P = 0.01), and EGFR overexpression(OR = 2.185, P = 0.044) were independent risk factors for lymph node involvement.CONCLUSION: Female gender, tumor size, lymphovascular invasion and EGFR overexpression were predictive risk factors for lymph node metastasis in EGC.Eun Hyo Jin Dong Ho Lee Sung-Ae Jung Ki-Nam Shim Ji Yeon Seo Nayoung Kim Cheol Min Shin Hyuk Yoon Hyun Chae Jung 2015World Journal of Gastroenterology2015,21,2:30
5Limited 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
6The CONSTANS-like 4 transcription factor,AtCOL_4,positively regulates abiotic stress tolerance through an abscisic acid-dependent manner in Arabidopsis显示文摘The precise roles of the B-box zinc finger family of transcription factors in plant stress are poorly understood.Functional analysis was performed on AtCOL4,an Arabidopsis thaliana L.CONSTANS-like 4 protein that is a putative novel transcription factor,and which contains a predicted transcriptional activation domain.Analyses of an AtCOL4 promoter-b-glucuronidase(GUS) construct revealed substantial GUS activity in whole seedlings.The expression of AtCOL4 was strongly induced by abscisic acid(ABA),salt,and osmotic stress.Mutation in atcol4 resulted in increased sensitivity to ABA and salt stress during seed germination and the cotyledon greening process.In contrast,AtCOL4-overexpressing plants were less sensitive to ABA and salt stress compared to the wild type.Interestingly,in the presence of ABA or salt stress,the transcript levels of other ABA biosynthesis and stress-related genes were enhanced induction in AtCOL4-overexpressing and WT plants,rather than in the atcol4 mutant.Thus,AtCOL4 is involved in ABA and salt stress response through the ABA-dependent signaling pathway.Taken together,these findings provide compelling evidence that AtCOL4 is an important regulator for plant tolerance to abiotic stress.Ji-Hee Min Jung-Sung Chung Kyeong-Hwan Lee Cheol Soo Kim 2015Journal of Integrative Plant Biology2015,57,3:23

8Effect of an Artificial Caudal Fin on the Performance of a Biomimetic Fish Robot Propelled by Piezoelectric Actuators显示文摘This paper addresses the design of a biomimetic fish robot actuated by piezoceramic actuators and the effect of artificial caudal fins on the fish robot's performance. The limited bending displacement produced by a lightweight piezocomposite actuator was amplified and transformed into a large tail beat motion by means of a linkage system. Caudal fins that mimic the shape of a mackerel fin were fabricated for the purpose of examining the effect of caudal fin characteristics on thrust pro-duction at an operating frequency range. The thickness distribution of a real mackerel's fin was measured and used to design artificial caudal fins. The thrust performance of the biomimetic fish robot propelled by fins of various thicknesses was examined in terms of the Strouhal number,the Froude number,the Reynolds number,and the power consumption. For the same fin area and aspect ratio,an artificial caudal fin with a distributed thickness shows the best forward speed and the least power con-sumption.Seok Heo Tedy Wiguna Hoon Cheol Park Nam Seo Goo 2007Journal of Bionic Engineering2007,4,3:16

10Tenofovir rescue therapy for chronic hepatitis B patients after multiple treatment failures显示文摘AIM:To evaluate the efficacy and safety of tenofovir disoproxil fumarate(TDF) for chronic hepatitis B(CHB) patients after multiple failures.METHODS:A total of 29 CHB patients who had a suboptimal response or developed resistance to two or more previous nucleoside/nucleotide analogue(NA) treatments were included.Study subjects were treated with TDF alone(n = 13) or in combination with lamivudine(LAM,n = 12) or entecavir(ETV,n = 4) for ≥ 6 mo.Complete virologic response(CVR) was defined as an achievement of serum hepatitis B virus(HBV) DNA level ≤ 60 IU/mL by real-time polymerase chain reaction method during treatment.Safety assessment was based on serum creatinine and phosphorus level.Eleven patients had histories of LAM and adefovir dipivoxil(ADV) treatment and 18 patients were exposed to LAM,ADV,and ETV.Twenty-seven patients(93.1%) were hepatitis B e antigen(HBeAg) positive and the mean value of the baseline serum HBV DNA level was 5.5 log IU/mL ± 1.7 log IU/mL.The median treatment duration was 16 mo(range 7 to 29 mo).RESULTS:All the patients had been treated with LAM and developed genotypic and phenotypic resistance to it.Resistance to ADV was present in 7 patients and 10 subjects had a resistance to ETV.One patient had a resistance to both ADV and ETV.The cumulative probabilities of CVR at 12 and 24 mo of TDF containing treatment regimen calculated by the Kaplan Meier method were 86.2% and 96.6%,respectively.Although one patient failed to achieve CVR,serum HBV DNA level decreased by 3.9 log IU/mL from the baseline and the last serum HBV DNA level during treatment was 85 IU/mL,achieving near CVR.No patients in this study showed viral breakthrough or primary non-response during the follow-up period.The cumulative probability of HBeAg clearance in the 27 HBeAg positive patients was 7.4%,12%,and 27% at 6,12,and 18 mo of treatment,respectively.Treatment efficacy of TDF containing regimen was not statistically different according to the presence of specific HBV mutations.History of prior exposure to specific antiviral agents did not make a difference to treatment outcome.Treatment efficacy of TDF was not affected by combination therapy with LAM or ETV.No patient developed renal toxicity and no cases of hypophosphatemia associated with TDF therapy were observed.There were no other adverse events related to TDF therapy observed in the study subjects.CONCLUSION:TDF can be an effective and safe rescue therapy in CHB patients after multiple NA therapy failures.Yu Jin Kim Dong Hyun Sinn Geum-Youn Gwak Moon Seok Choi Kwang Cheol Koh Seung Woon Paik Byung Chul Yoo Joon Hyeok Lee 2012World Journal of Gastroenterology2012,18,47:16
11Somatostatin adjunctive therapy for non-variceal upper gastrointestinal rebleeding after endoscopic therapy显示文摘AIM:To evaluate the effect of pantoprazole with a somatostatin adjunct in patients with acute non-variceal upper gastrointestinal bleeding(NVUGIB).METHODS:We performed a retrospective analysis of a prospective database in a tertiary care university hospital.From October 2006 to October 2008,we enrolled 101 patients with NVUGIB that had a high-risk stigma on endoscopy.Within 24 h of hospital admission,all patients underwent endoscopic therapy.After successful endoscopic hemostasis,all patients received an 80-mg bolus of pantoprazole followed by continuous intravenous infusion(8 mg/h for 72 h).The somatostatin adjunct group(n=49)also received a 250-μg bolus of somatostatin,followed by continuous infusion (250μg/h for 72 h).Early rebleeding rates,disappearance of endoscopic stigma and risk factors associated with early rebleeding were examined.RESULTS:Early rebleeding rates were not significantly different between treatment groups(12.2%vs 14.3%,P=0.766).Disappearance of endoscopic stigma on the second endoscopy was not significantly different between treatment groups(94.2%vs 95.9%,P=0.696).Multivariate analysis showed that the complete Rockall score was a significant risk factor for early rebleeding(P =0.044,OR:9.080,95%CI:1.062-77.595).CONCLUSION:The adjunctive use of somatostatin was not superior to pantoprazole monotherapy after successful endoscopic hemostasis in patients with NVUGIB.Cheol Woong Choi Dae Hwan Kang Hyung Wook Kim Su Bum Park Kee Tae Park Gwang Ha Kim Geun Am Song Mong Cho 2011World Journal of Gastroenterology2011,17,29:15

17Neonatal gastric perforation: A single center experience显示文摘AIM: To determine the etiology and prognostic factors for neonatal gastric perforation(NGP), a rare but life-threatening disease.METHODS: Between 1980 and 2011, nine patients un-derwent surgical intervention for NGP at Seoul National University Children's Hospital. The characteristics and prognosis of the patients were retrospectively analyzed.RESULTS: Among the nine patients, three(33.3%) were preterm babies and five(55.5%) had associated anomalies, which included diaphragmatic eventration(n = 2), congenital diaphragmatic hernia, esophageal atresia with tracheoesophageal fistula, and antral web. Three(33.3%) patients were born before 1990 and three(33.3%) had a birth weight < 2500 g. Pneumo-peritoneum was found on preoperative images in six(66.7%) patients, and incidentally in the other three(33.3%) patients. Surgery was performed within 24 h after the onset of symptoms in seven(77.8%) patients. The overall mortality rate was 22.2%(2/9). The time between symptoms and surgical intervention was the only prognostic factor for survival, whereas premature birth and birth weight were not.CONCLUSION: Early detection and advances in neo-natal intensive care may improve the prognosis of NGP.Jeik Byun Hyun Young Kim Seung Yeon Noh Soo Hong Kim Sung Eun Jung Seong Cheol Lee Kwi Won Park 2014World Journal of Gastrointestinal Surgery2014,6,8:13

19Is it possible to differentiate gastric GISTs from gastric leiomyomas by EUS?显示文摘AIM: To evaluate the ultrasonog raphy (EUS) features of gastric gastrointestinal stromal tumors (GISTs) as compared with gastric leiomyomas and then to determine the EUS features that could predict malignant GISTs.METHODS: We evaluated the endoscopic EUS features in 53 patients with gastric mesenchymal tumors conf irmed by histopathologic diagnosis. The GISTs were classif ied into benign and malignant groups according to the histological risk classif ication.RESULTS: Immunohistochemical analyses demon-strated 7 leiomyomas and 46 GISTs. Inhomogenicity, hyperechogenic spots, a marginal halo and higher echogenicity as compared with the surrounding muscle layer appeared more frequently in the GISTs than in the leiomyomas (P < 0.05). The presence of at least two of these four features had a sensitivity of 89.1% and a specifi city of 85.7% for predicting GISTs. Except for tumor size and irregularity of the border, most of the EUS features were not helpful for predicting the malignant potential of GISTs. On multivariate analysis, only the maximal diameter of the GISTs was an independent predictor. The optimal size for predicting malignant GISTs was 35 mm. The sensitivity and specificity using this value were 92.3% and 78.8%, respectively.CONCLUSION: EUS may help to differentiate gastric GISTs from gastric leiomyomas. Once GISTs are suspected, surgery should be considered if the size is greater than 3.5 cm.Gwang Ha Kim Do Youn Park Suk Kim Dae Hwan Kim Dong Heon Kim Cheol Woong Choi Jeong Heo Geun Am Song 2009World Journal of Gastroenterology2009,15,27:12
