1内皮细胞和平滑肌细胞氧化应激时Nrf2/ARE信号通路对抗氧化基因表达的调控:与动脉粥样硬化和先兆子痫的关系显示文摘动脉粥样硬化、糖尿病、慢性肾功能衰竭和先兆子痫等血管疾病时活性氧(reactive oxygen species,ROS)生成增加,容易导致内皮依赖性血管舒张功能的损害和血管损伤,而细胞可以诱导多种编码Ⅱ相解毒酶和抗氧化蛋白的基因表达,从而减轻ROS和亲电子物质介导的细胞损伤。一个被称为抗氧化反应元件(antioxidant response element,ARE)或亲电子反应元件(electrophile response element,EpRE)的顺式转录调控元件,可以介导诸如亚铁血红素加氧酶1、γ-谷氨酰半胱氨酸合成酶、硫氧还蛋白还原酶、谷胱甘肽-S转移酶和NAD(P)H:苯醌氧化还原酶等基因的转录。其他抗氧化酶,如超氧化物歧化酶、过氧化氢酶和非酶清除剂(如谷胱甘肽)等也参与ROS的清除。转录因子NF-E2相关因子2(nuclear factor-erythroid 2-related factor 2, Nrf2)是属于Cap‘n’Collar家族的转录因子,具有碱性亮氨酸拉链(basic region-leucine zipper,bZIP),它在ARE介导的抗氧化基因表达中起重要的作用。在正常情况下,Kelch样环氧氯丙烷相关蛋白-1(Kelch-like ECH-associated protein-1,Keapl)与Nrf2耦联,并与肌动蛋白细胞骨架结合被锚定于胞浆,但是在半胱氨酸残基发生氧化的情况下,Nrf2和Keapl解耦联,进入细胞核并与ARE结合,从而激活多种抗氧化基因和Ⅱ相解毒酶基因的转录。蛋白激酶C、丝裂原活化蛋白激酶和磷脂酰肌醇-3激酶参与Nrf2/ARE信号转导的调控。本文综述了有关Nrf2/ARE信号转导通路在血管稳态和动脉硬化、先兆子痫等疾病情况下内皮及平滑肌细胞对抗持续性氧化应激中起的作用。Giovanni E.

3Intestinal antigen-presenting cells in mucosal immune homeostasis:Crosstalk between dendritic cells,macrophages and B-cells显示文摘The intestinal immune system maintains a delicate balance between immunogenicity against invading pathogens and tolerance of the commensal microbiota.Inflammatory bowel disease(IBD)involves a breakdown in tolerance towards the microbiota.Dendritic cells(DC),macrophages(MΦ)and B-cells are known as professional antigen-presenting cells(APC)due to their specialization in presenting processed antigen to T-cells,and in turn shaping types of T-cell responses generated.Intestinal DC are migratory cells,unique in their ability to generate primary T-cell responses in mesenteric lymph nodes or Peyer’s patches,whilst MΦand B-cells contribute to polarization and differentiation of secondary T-cell responses in the gut lamina propria.The antigen-sampling function of gut DC and MΦenables them to sample bacterial antigens from the gut lumen to determine types of T-cell responses generated.The primary function of intestinal B-cells involves their secretion of large amounts of immunoglobulin A,which in turn contributes to epithelial barrier function and limits immune responses towards to microbiota.Here,we review the role of all three types of APC in intestinal immunity,both in the steady state and in inflammation,and how these cells interact with one another,as well as with the intestinal microenvironment,to shape mucosal immune responses.We describe mechanisms of maintaining intestinal immune tolerance in the steady state but also inappropriate responses of APC to components of the gut microbiota that contribute to pathology in IBD.Elizabeth R Mann Xuhang Li 2014World Journal of Gastroenterology2014,20,29:19
4A Review of the Functional and Anatomical Default Mode Network in Schizophrenia显示文摘Schizophrenia is a severe mental disorder characterized by impaired perception,delusions,thought disorder,abnormal emotion regulation,altered motor function,and impaired drive. The default mode network(DMN),since it was first proposed in 2001,has become a central research theme in neuropsychiatric disorders,including schizophrenia. In this review,first we define the DMN and describe its functional activity,functional and anatomical connectivity,heritability,and inverse correlation with the task positive network. Second,we review empirical studies of the anatomical and functional DMN,and anti-correlation between DMN and the task positive network in schizophrenia. Finally,we review preliminary evidence about the relationship between antipsychotic medications and regulation of the DMN,review the role of DMN as a treatment biomarker for this disease,and consider the DMN effects of individualized therapies for schizophrenia.Mao-Lin Hu Xiao-Fen Zong J.

5Transarterial chemoembolization using degradable starch microspheres and iodized oil in the treatment of advanced hepatocellular carcinoma: evaluation of tumor response, toxicity, and survival显示文摘BACKGROUND: In a multidisciplinary conference patients with advanced non-resectable hepatocellular carcinoma (HCC) were stratified according to their clinical status and tumor extent to different regional modalities or to best supportive care. The present study evaluated all patients who were stratified to repeated transarterial chemoembolization (TACE) from 1999 until 2003 in terms of tumor response, toxicity, and survival. A moderate embolizing approach was chosen using a combination of degradable starch microspheres (DSM) and iodized oil (Lipiodol) in order to combine anti-tumoral efficiency and low toxicity. METHODS: Fourty-seven patients were followed up prospectively. TACE treatment consisted of cisplatin (50 mg/m2), doxorubicin (50 mg/m2), 450-900 mg DSM, and 5-30 ml Lipiodol. DSM and Lipiodol were administered according to tumor vascularization. Patient characteristics,toxicity, and complications were outlined. In multivariate regression analyses of pre-treatment variables from a prospective database, predictors for tumor response and survival after TACE were determined. RESULTS: 112 TACE courses were performed (2.4±1.5 courses per patient). Mean maximum tumor size was 75 (± 43) mm, in 68% there was bilobar disease. Best response to TACE treatment was: progressive disease (PD) 9%, stable disease (SD) 55%, partial remission (PR) 36%, and complete remission (CR) 0%. Multivariate regression analyses identified tumor size ≤75 mm, tumor number ≤5, and tumor hypervascularization as predictors for PR. The overall 1-, 2-, and 3-year-survival rates were 75%, 59%, and 41%, respectively, and the median survival was 26 months. Low α-fetoprotein levels (<400 ng/ml) (Odds ratio=3.3) and PR as best response to TACE (Odds ratio=6.7) were significantly associated with long term survival (>30 months, R2=36%). Grade 3 toxicity occurred in 7.1% (n=8), and grade 4 toxicity in 3.6% (n=4) of all courses in terms of reversible leukopenia and thrombocytopenia. The incidence of major complications was 5.4% (n=6). All complications were managed conservatively. The mortality within 6 weeks after TACE was 2.1% (one patient). CONCLUSIONS: DSM and Lipiodol were combined successfully in the palliative TACE treatment of advanced HCC resulting in high rates of tumor response and survival at limited toxicity. Favourable tumor response was associated with tumor extent and vascularization. TACE using DSM and Lipiodol can be considered a suitable palliative measure in patients who might not tolerate long acting embolizing agents.Timm D Kirchhoff Joerg S Bleck Arne Dettmer Ajay Chavan Herbert Rosenthal Sonja Merkesdal Bernd Frericks Lars Zender Nisar P Malek Tim F Greten Stefan Kubicka Michael P Manns Michael Galanski 2007Hepatobiliary & Pancreatic Diseases International2007,6,3:15

11Role of endoscopy in predicting the disease course in inflammatory bowel disease显示文摘Endoscopy provides a direct evaluation of mucosal lesions in inflammatory bowel disease(IBD),permitting the description of elementary lesions,their surface extent and severity.The severity of mucosal lesions directly reflects disease activity and may help to identify an aggressive behavior of the disease.Several studies have recently pointed out the potential role of endoscopy in the prediction of IBD outcome.Indeed,severe endoscopic lesions in Crohn's disease(CD) patients,defined by deep and extensive ulcerations on at least one part of the colon,are associated with an increased risk of penetrating complication and surgery.Severe endoscopic lesions during severe attacks of ulcerative colitis(UC) are associated with an increased risk of colectomy in the short and long term.Severity of postoperative recurrence in CD may help to predict the risk of clinical relapse and need for further surgery.Achievement of mucosal healing,which can be obtained by administration of several types of drugs,is associated with a better outcome,less surgery and hospitalization.This review focuses on the assessment of endoscopic severity in CD and UC and on the impact of endoscopic severity on disease outcome.More specifically,we discuss how endoscopy can be used at different stages of IBD to predict the disease course and/or to adapt treatment strategies.Matthieu Allez Marc Lémann 2010World Journal of Gastroenterology2010,16,21:10
12Association of chronic viral hepatitis B with insulin resistance显示文摘AIM:To investigate the relationship between chronic viral hepatitis B(CVHB) and insulin resistance(IR) in Korean adults.METHODS:A total of 7880 adults(3851 men,4029 women) who underwent a comprehensive medical examination were enrolled in this study.Subjects diagnosed with either diabetes mellitus,or any other disorder that could influence their insulin sensitivity,were rejected.Anthropometry,metabolic risk factors,hepatitis B surface antigen,hepatitis B surface antibody,hepatitis B core antibody,fasting plasma glucose and insulin were measured for all subjects.Homeostasis model assessment(HOMA),quantitative insulin check index(QUICKI),and Mf fm index were used for determining insulin sensitivity.Each participant was categorized into a negative,recovery,or CVHB group.To compare variables between groups,a t-test and/or one-way analysis of variance were used.Partial correlation coefficients were computed to present the association between insulin resistance and other variables.Multiple logistic regression analysis was used to assess the independent association between CVHB and IR.RESULTS:The mean age of men and women were 48.9 and 48.6 years,respectively.Subjects in the CVHB group had significantly higher waist circumference [(86.0 ± 7.7 cm vs 87.3 ± 7.8 cm,P = 0.004 in men),(78.3 ± 8.6 cm vs 80.5 ± 8.5 cm,P < 0.001 in women)],cystatin C [(0.96 ± 0.15 mg/dL vs 1.02 ± 0.22 mg/dL,P < 0.001 in men),(0.84 ± 0.15 mg/dL vs 0.90 ± 0.16 mg/dL,P < 0.001 in women)],fasting insulin [(5.47 ± 3.38 U/mL vs 6.12 ± 4.62 U/mL,P < 0.001 in men),(4.57 ± 2.82 U/mL vs 5.06 ± 3.10 U/mL,P < 0.001 in women)] and HOMA index [(1.24 ± 0.86 vs 1.43 ± 1.24,P < 0.001 in men),(1.02 ± 0.76 vs 1.13 ± 0.87,P = 0.033 in women)] compared to control group.The HOMA index revealed a positive correlation with body mass index(BMI)(r = 0.378,P < 0.001),waist circumference(r =0.356,P < 0.001),percent body fat(r = 0.296,P < 0.001),systolic blood pressure(r = 0.202,P < 0.001),total cholesterol(r = 0.134,P < 0.001),triglycerides(r = 0.292,P < 0.001),cystatin C(r = 0.069,P < 0.001) and uric acid(r = 0.142,P < 0.001).The QUICKI index revealed a negative correlation with BMI(r =-0.254,P < 0.001),waist circumference(r = 0-0.243,P < 0.001),percent body fat(r =-0.217,P < 0.001),systolic blood pressure(r =-0.132,P < 0.001),total cholesterol(r =-0.106,P < 0.001),triglycerides(r =-0.205,P < 0.001),cystatin C(r =-0.044,P < 0.001) and uric acid(r =-0.096,P < 0.001).For subjects identified with IR,the odds ratio of an accompanying diagnosis of chronic hepatitis B was 1.534(95% CI:1.158-2.031,HOMA index criteria) or 1.566(95% CI:1.124-2.182,QUICKI criteria) after adjustment for age,gender,BMI,and amount of alcohol consumption.CONCLUSION:Our study demonstrates that CVHB is associated with IR.CVHB may need to be monitored for occurrence of IR and diabetes mellitus.Jeong Gyu Lee Sangyeoup Lee Yun Jin Kim Byung Mann Cho Joo Sung Park Hyung Hoi Kim JaeHun Cheong Dong Wook Jeong Yu Hyun Lee Young Hye Cho Mi Jin Bae Eun Jung Choi 2012World Journal of Gastroenterology2012,18,42:10
