| 1 | Clinicopathological significance of altered Notch signaling in extrahepatic cholangiocarcinoma and gallbladder carcinoma显示文摘AIM:To investigate the role and clinicopathological significance of aberrant expression of Notch receptors and Delta-like ligand-4 (DLL4) in extrahepatic cholangiocarcinoma and gallbladder carcinoma.METHODS:One hundred and ten patients had surgically resected extrahepatic cholangiocarcinoma (CC) and gallbladder carcinoma specimens examined by immunohistochemistry of available paraffin blocks.Immunohistochemistry was performed using anti-Notch receptors 1-4 and anti-DLL4 antibodies.We scored the immunopositivity of Notch receptors and DLL4 expression by percentage of positive tumor cells with cytoplasmic expression and intensity of immunostaining.Coexistent nuclear localization was evaluated.Clinicopatho-logical parameters and survival data were compared with the expression of Notch receptors 1-4 and DLL4.RESULTS:Notch receptor proteins showed in the cytoplasm with or without nuclear expression in cancer cells,as well as showing weak cytoplasmic expression in non-neoplastic cells.By semiquantitative evaluation,positive immunostaining of Notch receptor 1 was detected in 96 cases (87.3%),Notch receptor 2 in 97 (88.2%),Notch receptor 3 in 97 (88.2%),Notch receptor 4 in 103 (93.6),and DLL4 in 84 (76.4%).In addition,coex- istent nuclear localization was noted [Notch receptor 1;18 cases (18.8%),Notch receptor 2;40 (41.2%),Notch receptor 3;32 (33.0%),Notch receptor 4;99 (96.1%),DLL4;48 (57.1%)].Notch receptor 1 expression was correlated with advanced tumor,node,metastasis (TNM) stage (P=0.043),Notch receptor 3 with advanced T stage (P=0.017),tendency to express in cases with nodal metastasis (P=0.065) and advanced TNM stage (P=0.052).DLL4 expression tended to be related to less histological differentiation (P=0.095).Coexistent nuclear localization of Notch receptor 3 was related to no nodal metastasis (P=0.027) and Notch receptor 4 with less histological differentiation (P=0.036),while DLL4 tended to be related inversely with T stage (P=0.053).Coexistent nuclear localization of DLL4 was related to poor survival (P=0.002).CONCLUSION:Aberrant expression of Notch receptors 1 and 3 play a role during cancer progression,and cytoplasmic nuclear coexistence of DLL4 expression correlates with poor survival in extrahepatic CC and gallbladder carcinoma. | Hyun Ah Yoon Myung Hwan Noh Byung Geun Kim Ji Sun Han Jin Seok Jang Seok Ryeol Choi Jin Sook Jeong Jin Ho Chun | 2011 | World Journal of Gastroenterology2011，17，35： | 14 |
| 2 | Asymptomatic lymphangioma involving the spleen and retroperitoneum in adults显示文摘Lymphangioma,a benign neoplasm of the lymphatic system,is common in children but rare in adults.Its clinical manifestations include abdominal pain,nausea, vomiting and a palpable mass.However,abdominal sonography or abdominal computed tomography(CT) scan can also incidentally reveal lymphangioma.A larger or symptomatic lymphangioma is treated with total resection to prevent recurrence,infection,torsion and enlargement.Although lymphangioma rarely becomes malignant,its prognosis is generally good. We report a cystic lymphangioma of the spleen and retroperitoneum,which was incidentally found in a 56-year-old man who was hospitalized due to a colon mass.Physical examination showed no specific findings.Abdominal CT revealed a 5.7 cm,non-enhanced multilobulated cystic mass with multiple septa in the spleen and a 10 cm lobulated cystic mass in the paraaortic area.Splenectomy and retroperitoneal resection of the cystic mass were conducted.The endotheliumof splenic and retroperitoneal cyst was immunohisto- chemically stained with D2-40 antibody.The patient was finally diagnosed with splenic cystic and retroperitoneal cavernous lymphangioma. | Sook Hee Chung Young Sook Park Yun Ju Jo Seong Hwan Kim Dae Won Jun Byoung Kwan Son Jun Young Jung Dae Hyun Baek Dong Hee Kim Yoon Young Jung Won Mi Lee | 2009 | World Journal of Gastroenterology2009，15，44： | 7 |

| 11 | Superior gallstone dissolubility and safety of tert-amyl ethyl ether over methyl-tertiary butyl ether显示文摘BACKGROUND The use of methyl-tertiary butyl ether(MTBE)to dissolve gallstones has been limited due to concerns over its toxicity and the widespread recognition of the safety of laparoscopic cholecystectomy.The adverse effects of MTBE are largely attributed to its low boiling point,resulting in a tendency to evaporate.Therefore,if there is a material with a higher boiling point and similar or higher dissolubility than MTBE,it is expected to be an attractive alternative to MTBE.AIM To determine whether tert-amyl ethyl ether(TAEE),an MTBE analogue with a relatively higher boiling point(102°C),could be used as an alternative to MTBE in terms of gallstone dissolubility and toxicity.METHODS The in vitro dissolubility of MTBE and TAEE was determined by measuring the dry weights of human gallstones at predetermined time intervals after placing them in glass containers with either of the two solvents.The in vivo dissolubility was determined by comparing the weights of solvent-treated gallstones and control(dimethyl sulfoxide)-treated gallstones,after the direct infusion of each solvent into the gallbladder in both hamster models with cholesterol and pigmented gallstones.RESULTS The in vitro results demonstrated a 24 h TAEE-dissolubility of 76.7%,56.5%and 38.75%for cholesterol,mixed,and pigmented gallstones,respectively,which represented a 1.2-,1.4-,and 1.3-fold increase in dissolubility compared to that of MTBE.In the in vitro experiment,the 24 h-dissolubility of TAEE was 71.7%and 63.0%for cholesterol and pigmented gallstones,respectively,which represented a 1.4-and 1.9-fold increase in dissolubility compared to that of MTBE.In addition,the results of the cell viability assay and western blot analysis indicated that TAEE had a lower toxicity towards gallbladder epithelial cells than MTBE.CONCLUSION We demonstrated that TAEE has higher gallstone dissolubility properties and safety than those of MTBE.As such,TAEE could present an attractive alternative to MTBE if our findings regarding its efficacy and safety can be consistently reproduced in further subclinical and clinical studies. | Dong Do You Suk Joon Cho Ok-Hee Kim Jin Sook Song Kyu-Seok Hwang Sang Chul Lee Kee-Hwan Kim Ho Joong Choi Ha-Eun Hong Haeyeon Seo Tae Ho Hong Jung Hyun Park Tae Yoon Lee Joseph Ahn Jae-Kyung Jung Kwan-Young Jung Say-June Kim | 2019 | World Journal of Gastroenterology2019，25，39： | 1 |

| 14 | Microscopic characteristics of the inferior tarsal muscle and its surroundings in Korean显示文摘AIM: To investigate the detailed microscopic anatomic structures of the lower eyelid in Korean cadavers. METHODS: Eight lower eyelids of 4 formalin-fixed Asian cadavers (4 males; age range, 48-69 years; mean age, 60.2 years) were examined. Three perpendicular dissected sections with a 2mm thickness were obtained from each eyelid to investigate anatomic shapes, size and relationship with surrounding structures. One section was obtained from the midline and 2 the other sections were obtained from a 3mm apart from the lateral and medial tarsus margins. RESULTS: The inferior tarsal muscle fibers were not directly attached to the tarsus but were only linked to the tarsus with enclosed fibrous fascia. The inferior tarsal muscles connected loosely with the capsulopalpebral fascia anteriorly and the conjunctiva posteriorly. The inferior tarsal muscle runs horizontally to the tarsus according to the shape of muscle fibers. The capsulopalpebral fascia consisted of an anterior and posterior layer. The anterior layer reached the orbital septum and subcutaneous fat but the posterior layer forwarded into the tarsus. Lockwood's ligament was separated from the inferior tarsal muscle and capsulopalpebral fascia or fused into the capsulopalpebral fascia.CONCLUSION: This study suggests that the inferior tarsal muscle which runs horizontally and doesn't insert directly into the tarsus, plays an important role in the movement and localization of the lower eyelid. | Jung Min Park Mee Sook Roh Moo Hyun Kim Woo Jin Jeung Won Yeol Ryu Yoon Hyung Kwon Hee Bae Ahn | 2013 | International Journal of Ophthalmology(English edition)2013，6，2： | 0 |
| 15 | Congenital retinal macrovessel with intracranial venous malformation in a pediatric patient: a case report显示文摘Dear Editor,Congenital retinal macrovessel (CRM) is defined as an abnormal large retinal vessel that encircles the foveal avascular zone (FAZ).Since the first description of a large aberrant vessel crossing the macula by Mauthnerin 1868,there have been several case reports about CRM.And recently,Pichi et alreported clinical manifestations and multimodal retinal imaging of 49 eyes with CRM.In their study,they had identified an association between macrovessel in the retina and venous anomalies of the brain and they emphasized the importance of systemic workups including brain magnetic resonance imaging (MRI). | Hyeon Jin Park Sook Hyun Yoon Sook Young Kim Donghun Lee | 2022 | International Journal of Ophthalmology(English edition)2022，15，7： | 0 |
