1Clinicopathological 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 2011World Journal of Gastroenterology2011,17,35:14
2Antioxidative and anti-endotoxin effects of propofol on endothelial cells显示文摘Objective To investigate the antioxidant and anti-endotoxin effects of propofol on endothelial cells and the possible mechanisms.Methods Cultured endothelial cells were treated with hydrogen peroxide (H 2O 2), propofol + H 2O 2, lipopolysaccharide (LPS) and propofol + LPS, respectively. Endothelial cell damage was monitored for possible lactic dehydrogenase (LDH) release. The transcription and the protein expression levels of endothelial nitric oxide synthase (eNOS) were measured.Results LDH release was higher in groups treated with H 2O 2 or LPS than in the control group. After pretreatment with propofol, the effects induced by H 2O 2 were attenuated, but propofol did not decrease the LDH release induced by LPS. Both H 2O 2 and LPS significantly increased the eNOS transcript levels and the increases were significantly attenuated after pretreatment with propofol. Both H 2O 2 and LPS significantly increased the eNOS protein expression and the increase was attenuated after pretreatment with propofol. Conclusion Propofol could protect endothelial cells against oxidative stress by inhibiting eNOS transcription and protein expression, but could not antagonise endotoxin induced cell injuries.彭志勇 罗敏 叶仕桥 Critchley Lester AH Joynt Gavin M Ho Anthony MH 姚尚龙 2003Chinese Medical Journal2003,,5:7
3Differential diagnosis of left-sided abdominal pain:Primary epiploic appendagitis vs colonic diverticulitis显示文摘AIM:To investigate the clinical characteristics of left primary epiploic appendagitis and to compare them with those of left colonic diverticulitis.METHODS:We retrospectively reviewed the clinical records and radiologic images of the patients who presented with left-sided acute abdominal pain and had computer tomography(CT) performed at the time of presentation showing radiological signs of left primary epiploic appendagitis(PEA) or left acute colonic diverticulitis(ACD) between January 2001 and December 2011. A total of 53 consecutive patients were enrolled and evaluated. We also compared the clinical characteristics,laboratory findings,treatments,and clinical results of left PEA with those of left ACD.RESULTS:Twenty-eight patients and twenty-five patients were diagnosed with symptomatic left PEA and ACD,respectively. The patients with left PEA had focal abdominal tenderness on the left lower quadrant(82.1%). On CT examination,most(89.3%) of the patients with left PEA were found to have an oval fatty mass with a hyperattenuated ring sign. In cases of left ACD,the patients presented with a more diffuse abdominal tenderness throughout the left side(52.0%vs 14.3%; P = 0.003). The patients with left ACD had fever and rebound tenderness more often than those with left PEA(40.0% vs 7.1%,P = 0.004; 52.0% vs14.3%,P = 0.003,respectively). Laboratory abnormalities such as leukocytosis were also more frequently observed in left ACD(52.0% vs 15.4%,P = 0.006).CONCLUSION:If patients have left-sided localized abdominal pain without associated symptoms or laboratory abnormalities,clinicians should suspect the diagnosis of PEA and consider a CT scan.Jeong Ah Hwang Sun Moon Kim Hyun Jung Song Yu Mi Lee Kyung Min Moon Chang Gi Moon Hoon Sup Koo Kyung Ho Song Yong Seok Kim Tae Hee Lee Kyu Chan Huh Young Woo Choi Young Woo Kang Woo Suk Chung 2013World Journal of Gastroenterology2013,19,40:6
4Perceived risk as a barrier to appropriate diagnosis of irritable bowel syndrome显示文摘AIM:To evaluate perceived risk,diagnostic testing,and acceptance of a diagnosis of irritable bowel syndrome(IBS)among the Korean laypersons.METHODS:We designed a conceptual framework to evaluate the health-seeking behavior of subjects based on a knowledge,attitude,and practice model.We developed a vignette-based questionnaire about IBS based on a literature review and focused group interviews.The vignette described a 40-year-old woman who meets the RomeⅢcriteria for IBS without red-flag signs.It was followed by questions about demographic characteristics,health behaviors,IBS symptoms,risk perception,perceived need for diagnostic tests,and acceptance of a positive diagnosis of IBS.Weplanned a nationwide survey targeting laypersons without IBS and between the ages of 20 and 69 years.Survey participants were selected by quota sampling stratified by gender,age,and nationwide location.A multivariate logistic model was constructed based on literature reviews,univariate analysis,and a stepwise selection method to investigate correlations between the perceived risk,need for diagnostic tests,and acceptance of a positive diagnosis.RESULTS:Of 2354 eligible households,1000 subjects completed the survey and 983 subjects were analyzed,excluding those who met symptom criteria for IBS.After reading the IBS vignette,the majority of subjects(86.8%)responded that the patient was at increased risk of severe disease.The most frequent concern was colon cancer(59.8%),followed by surgical condition(51.5%).Most subjects responded the patient needs diagnostic tests(97.2%).Colonoscopy was the most commonly required test(79.5%).Less than half of the respondents requested a stool examination(45.0%),blood test(40.7%),abdominal ultrasound(36.0%),or computed tomography(20.2%).The subjects who felt increased risk were more likely to see a need for colonoscopy[adjusted odds ratio(a OR)=2.10,95%CI:1.38-3.18].When asked about the positive diagnosis,the most frequent response was that'the patient would not be reassured'(65.7%).The increased risk perception group was less likely to be reassured by a positive diagnosis of IBS,compared to the other respondents(a OR=0.52,95%CI:0.34-0.78).CONCLUSION:For IBS diagnosis,increased risk perception is a possible barrier to the appropriate use of diagnostic tests and to the patient’s acceptance of a positive diagnosis.Eunmi Ahn Ki Young Son Dong Wook Shin Min Kyu Han Hyejin Lee Ah Reum An Eun Ho Kim Be Long Cho 2014World Journal of Gastroenterology2014,20,48:2
5N-terminal pro-B-type natriuretic peptide as prognostic marker for patients of non ST-segment elevation myocardial infarction显示文摘In this work, we analyzed only the patients of the NSTEMI (non ST-segment elevation myocardial infarction) who arrived at the hospital within 12 h after symptoms started. Using NSTEMI follow-up data within, the characteristics of the clinical data, the risk factor, and the blood tested in the hospital visit were analyzed for MACE (major adverse cardiac events) patients. MACE includes cardiac death, MI (myocardial infarction), Re-PCI, and CABG (coronary artery bypass graft). As a result, from the NSTEMI patients which can be followed up for over 12 m, NT-ProBNP (p=0.014) and age (p=0.045) are found to be the independent risk factors related to MACE. Accordingly, they can be useful for the diagnosis and prognosis for NSTEMI patients as a biomarker.SHON Ho Sun HWANG Kyung Kuk BAE Jang Whan KIM Kyung Ah LEE Jong Yun RYU Keun Ho 2013Journal of Central South University2013,20,8:2

7Changes in a cerebellar peduncle lesion in a patient with Dandy-Walker malformation A diffusion tensor imaging study显示文摘We report a patient with severe ataxia due to Dandy-Walker malformation, who showed functional recovery over 10 months corresponding to a change in a cerebellar peduncle lesion. A 20-month-old female patient who was diagnosed with Dandy-Walker syndrome and six age- and sex-matched healthy control subjects were enrolled. The superior cerebellar peduncle, the middle cerebellar peduncle, and the inferior cerebellar peduncle were evaluated using fractional anisotropy and the apparent diffusion coefficient. The patients' functional ambulation category was 0 at the initial visit, but improved to 2 at the follow-up evaluation, and Berg's balance scale score also improved from 0 to 7. Initial diffusion tensor tractography revealed that the inferior cerebellar peduncle was not detected, that the fractional anisotropy of the superior cerebellar peduncle and middle cerebellar peduncle decreased by two standard deviations below, and that the apparent diffusion coefficient increased by two standard deviations over normal control values. However, on follow-up diffusion tensor tractography, both inferior cerebellar peduncles could be detected, and the fractional anisotropy of superior cerebellar peduncle increased to within two standard deviations of normal controls. The functional improvement in this patient appeared to correspond to changes in these cerebellar peduncles. We believe that evaluating cerebellar peduncles using diffusion tensor imaging is useful in cases when a cerebellar peduncle lesion is suspected.Ah Young Lee Sung Ho Jang Sang Seok Yeo Ensil Lee Yun Woo Cho Su Min Son 2013Neural Regeneration Research2013,8,5:2
