| 1 | Expression 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 | 2005 | World Journal of Gastroenterology2005，11，14： | 62 |
| 2 | Limited 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 | 2010 | World Journal of Gastroenterology2010，16，34： | 26 |

| 4 | Effect 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 | 2007 | Journal of Bionic Engineering2007，4，3： | 16 |

| 10 | Neonatal 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 | 2014 | World Journal of Gastrointestinal Surgery2014，6，8： | 13 |
| 11 | Is 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 | 2009 | World Journal of Gastroenterology2009，15，27： | 12 |

| 13 | Curcumin attenuates the release of pro-inflammatory cytokines in lipopolysaccharide-stimulated BV2 microglia显示文摘Aim:Pro-inflammatory mediators,such as prostaglandin E_2 (PGE_2) and nitric oxide(NO),and pro-inflammatory cytokines such as interleukin (IL)-1β,IL-6,and TNF-α,play pivotal roles in brain injuries.The anti-inflammatory properties are knownto be associated with significant reductions in pro-inflammatory mediators in braininjuries.In the present study we investigate whether the effects of curcumin onthe production of pro-inflammatory mediators in lipopolysaccharide (LPS)-stimu-lated BV2 microglia.Methods:Curcumin were administered and their effects onLPS-induced pro-inflammatory mediators were monitored by Western blottingand RT-PCR.Result:Curcumin significantly inhibited the release of NO,PGE_2,and pro-inflammatory cytokines in a dose-dependent manner.Curcumin alsoattenuated the expressions of inducible NO synthase and cyclooxygenase-2 mRNAand protein levels.Moreover,curcumin suppressed NF-kB activation via thetranslocation of p65 into the nucleus.Our data also indicate that curcumin exertsanti-inflammatory properties by suppressing the transcription of proinflammatorycytokine genes through the NF-kB signaling pathway.Conclusion:Anti-inflam-matory properties of curcumin may be useful for treating the inflammatory anddeleterious effects of microglial activation in response to LPS stimulation. | Cheng-yun JIN Jae-dong LEE Cheol PARK Yung hyun CHOI Gi-young KIM | 2007 | Acta Pharmacologica Sinica2007，28，10： | 10 |
| 14 | Multiplanar reformations and minimum intensity projections using multi-detector row CT for assessing anomalies and disorders of the pancreaticobiliary tree显示文摘CT scan is regarded as the imaging modality of choice in patients with pancreaticobiliary ductal abnormalities. However, the axial orientation of the CT images provides only limited anatomical view of pancreaticobiliary ductal abnormalities. The technological advances of multi-de-tector row CT and three-dimensional image processing in workstations allows rapid image acquisition and a short postprocessing time. In particular, multiplanar reforma-tions (MPR) and minimum intensity projections (MinIP) offer rapid and accurate images of the anatomy and ab-normalities of the pancreaticobiliary tree. Moreover, MPR and MinIP help determine the relationship between the pancreaticobiliary ductal anatomy and the surrounding structures. This pictorial review illustrates the wide spec-trum of images obtained by the MPR and MinIP of the anomalies and disorders of the pancreaticobiliary tree. | Hyun Cheol Kim Dal Mo Yang Wook Jin Chang Woo Ryu Jung Kyu Ryu Sung Il Park Seong Jin Park Hyeong Cheol Shin Il Young Kim | 2007 | World Journal of Gastroenterology2007，13，31： | 10 |
| 15 | Differentiation of hepatocellular carcinoma from its variousmimickers in liver magnetic resonance imaging:What arethe tips when using hepatocyte-specific agents?显示文摘Hepatocellular carcinoma is the most common primary hepatic malignant tumor.With widespread use of liver imaging,various cirrhosis-related nodules are frequently detected in patients with chronic liver disease,while diverse hypervascular hepatic lesions are incidentally detected but undiagnosed on dynamic computed tomography and magnetic resonance imaging(MRI).However,use of hepatocyte-specific MR contrast agents with combined perfusion and hepatocyte-selective properties have improved diagnostic performance in detection and characterization of focal liver lesions.Meanwhile,the enhancement patterns observed during dynamic phases using hepatocyte-specific agents may be different from those observed during MRI using conventional extracellular fluid agents,leading to confusion in diagnosis.Therefore,we discuss useful tips for the differentiation of hepatocellular carcinoma from similar lesions in patients with and without chronic liver disease using liver MRI with hepatocyte-specific agents. | Yang Shin Park Chang Hee Lee Jeong Woo Kim Sora Shin Cheol Min Park | 2016 | World Journal of Gastroenterology2016，22，1： | 10 |

| 18 | Wetting Characteristics of Insect Wing Surfaces显示文摘Biological tiny structures have been observed on many kinds of surfaces such as lotus leaves,which have an effect on thecoloration of Morpho butterflies and enhance the hydrophobicity of natural surfaces.We investigated the micro-scale andnano-scale structures on the wing surfaces of insects and found that the hierarchical multiple roughness structures help in enhancingthe hydrophobicity.After examining 10 orders and 24 species of flying Pterygotan insects,we found that micro-scaleand nano-scale structures typically exist on both the upper and lower wing surfaces of flying insects.The tiny structures such asdenticle or setae on the insect wings enhance the hydrophobicity,thereby enabling the wings to be cleaned more easily.And thehydrophobic insect wings undergo a transition from Cassie to Wenzel states at pitch/size ratio of about 20.In order to examinethe wetting characteristics on a rough surface,a biomimetic surface with micro-scale pillars is fabricated on a silicon wafer,which exhibits the same behavior as the insect wing,with the Cassie-Wenzel transition occurring consistently around apitch/width value of 20. | Doyoung Byun Jongin Hong Saputra Jin Hwan Ko Young Jong Lee Hoon Cheol Park Bong-Kyu Byun Jennifer R.Lukes | 2009 | Journal of Bionic Engineering2009，6，1： | 9 |
| 19 | Prediction of liver cirrhosis, using diagnostic imaging tools显示文摘Early diagnosis of liver cirrhosis is important. Ultrasoundguided liver biopsy is the gold standard for diagnosis of liver cirrhosis. However, its invasiveness and sampling bias limit the applicability of the method. Basic imaging for the diagnosis of liver cirrhosis has developed over the last few decades, enabling early detection of morphological changes of the liver by ultrasonography(US), computed tomography, and magnetic resonance imaging(MRI). They are also accurate diagnostic methods for advanced liver cirrhosis, for which early diagnosis is difficult. There are a number of ways to compensate for this difficulty, including texture analysis to more closely identify the homogeneity of hepatic parenchyma, elastography to measure the stiffness and elasticity of the liver, and perfusion studies to determine the blood flow volume, transit time, and velocity. Amongst these methods, elastography using US and MRI was found to be slightly easier, faster, and able to provide an accurate diagnosis. Early diagnosis of liver cirrhosis using MRI or US elastography is therefore a realistic alternative, but further research is still needed. | Suk Keu Yeom Chang Hee Lee Sang Hoon Cha Cheol Min Park | 2015 | World Journal of Hepatology2015，7，17： | 9 |
