2滇西哀牢山构造带:结构与演化显示文摘哀牢山构造带是藏东(东南亚)地区的一条重要线性构造,它分隔了扬子—华南地块与印支地块,并保存了多阶段复杂大地构造演化的记录。哀牢山构造带内由东向西依次发育了晚太古代—新元古代深变质岩系、新生代构造-岩浆活动带(剪切带)、金平—沱江晚二叠—早三叠世裂谷带残余和哀牢山早石炭世—早三叠世混杂岩带。具有不同特点的地质单元间被以新生代为主发育的断裂构造所间隔;而不同时期异地就位或混合岩化成因的花岗质岩石在构造带中普遍存在。哀牢山构造带在不同地质历史阶段具有多重大地构造属性,总体上经历了3个重要大地构造演化阶段:前特提斯演化、特提斯演化和新生代陆内演化阶段。前特提斯演化时期,主体部分(尤其是其东部带)具有亲扬子地块的属性,保留了自晚太古代到新元古代地壳演化的记录。一直到早古生代时期,哀牢山构造带的大地构造属性与扬子—华南地区依然具有密切的亲缘关系。自晚古生代—早中生代时期古特提斯洋打开之后,该带与华南-扬子板块之间分化成2个属性不同的构造域,始于早石炭世打开的哀牢山洋与始于早二叠世打开的金平—沱江洋依次消亡。特提斯洋的闭合,一方面形成了古哀牢山造山带,同时使得扬子—华南地块与印支地块回复到一个统一的陆内环境中;印度—欧亚板块之间的交互作用,对这一地区有着深刻的影响,相继形成了早新生代哀牢山造山带、晚渐新世—早中新世造山后区域性伸展与高钾碱性岩浆活动性和晚渐新世—早中新世印支地块的大规模南东向逃逸、哀牢山大型左行走滑剪切作用及伴生的钙碱性岩浆活动性。刘俊来 唐渊 宋志杰 Tran My Dung 翟云峰 吴文彬 陈文 2011吉林大学学报(地球科学版)2011,41,5:65

4奠边府走滑断裂带的构造特征、遥感解译及其区域构造意义显示文摘位于越南西北部的奠边府(Dien Bien Phu)断裂,向北延伸入中国云南境内,向南进入老挝境内,走向由近N—S向向南逐渐过渡为NE—SW向,倾角陡立。沿断裂带发育3个具有不同运动学机制的第四纪盆地——婵讷(Chan Nua)盆地、莱州(Lai Chau)盆地和奠边府盆地。根据对奠边府断裂带地区ETM遥感数据进行详细解译以及野外实地考察,得到奠边府断裂具有早期的右行走滑和后期的左行走滑特征的证据;并且根据断裂两侧水系受断裂影响发生左错的程度不同,认为奠边府断裂的西盘相对于东盘较为活动,即为主动盘。奠边府断裂北延进入越南境内,与金平地区的三家河断裂相连,并继续向北并入哀牢山剪切带中。奠边府断裂现今的左行走滑与红河断裂现今的右行走滑共同组成了一组共轭断裂系。唐渊 刘俊来 TRAN My Dungh 宋志杰 2009地质学报2009,83,10:17
5Acute and persisting Th2-like immune response after fractionated colorectal γ-irradiation显示文摘AIM:To investigate if an immune imbalance may account for the development and progression of chronic radiation enteritis.We analyzed the Th1/Th2 immune response profile early and 6 mo after fractionated colorectal irradiation. METHODS:A rat model of fractionated colorectal γ-irradiation(4-Gy fractions,3 fractions per week)was designed to investigate the effects of cumulative dose on inflammatory mediators(cytokines and chemo- kines)and immune response(Th1/Th2 profile and im- munosuppressive mediator IL-10)during acute(early) response and 6 mo after the end of fractionated irradia- tion(chronic response).Analyses were performed 1 d after the cumulative doses of 16 Gy and 36 Gy and 1 d, 3 d,and 26 wk after the cumulative dose of 52 Gy. RESULTS:Without causing histological damage,fractionated radiation induced elevated expression of IL-1β, TNFα,MCP-1,and iNOS in distal colonic mucosa during the early post-irradiation phase.At that time,a Th2 profile was confirmed by expression of both the Th2-specific transcription factor GATA-3 and the chemokine receptor CCR4 and by suppression of the Th1 cytokine IFNγ/IP-10 throughout the irradiation protocol.After 6 mo,despite the 2-fold reduction of iNOS and MCP-1 levels,the Th2 profile persisted,as shown by a 50% reduction in the expression of the Th1 transcription factor T-bet,the chemokine receptor CCXCR3,and the IFNγ/ STAT1 pathway.At the same time-point,the immuno-suppressive IL-10/STAT3 pathway,known to regulate the Th1/Th2 balance,was expressed,in irradiated rats, at approximately half its level as compared to controls.This suppression was associated with an overexpression of SOCS3,which inhibits the feedback of the Th1 polarization and regulates IL-10 production. CONCLUSION:Colorectal irradiation induces Th2 polarization,defective IL-10/STAT3 pathway activation and SOCS3 overexpression.These changes,in turn,maintain a immunological imbalance that persists in the long term.Olivier Grémy Marc Benderitter Christine Linard 2008World Journal of Gastroenterology2008,14,46:15

10Measurement of calprotectin in ascitic fluid to identify elevated polymorphonuclear cell count显示文摘AIM: To evaluate the diagnostic capability of calprotectin in ascitic fluid for detecting a polymorphonuclear (PMN) cell count > 250/μL ascites. METHODS: In this prospective observational study, a total of 130 ascites samples were analysed from 71 consecutive patients referred for paracentesis. Total and differential leukocyte cell counts were determined manually with a Neubauer chamber and gentianviolet stain. Calprotectin was measured in 1 mL ascetic fluid by enzyme-linked immunosorbent assay (ELISA) and a point-of-care (POC) lateral flow assay with the Quantum Blue Reader (Bühlmann Laboratories). All measurements were carried out in a central laboratory by senior personnel blinded to patient history. A PMN count > 250/μL was the primary endpoint of the study. The diagnostic value of ascitic calprotectin measurement was assessed by comparing to the final diagnosis of each patient that had been adjudicated by investigators blinded to calprotectin values. RESULTS: The PMN count was > 250/μL in 19 samples (14.6%) from 15 patients (21.1%) and varied widely among the study population (range 10-19 800/mL and 1-17 820/mL, respectively). Spontaneous bacterial peritonitis (SBP) was the final diagnosis in four patients (5.6%). All patients with PMN ≤ 250/μL had negative bacterial culture. PMN count was elevated in five patients with peritoneal carcinomatosis, three with lymphoma, one with neuroendocrine carcinoma, and two with secondary peritonitis due to abdominal perforation. PMN cell counts correlated with ascitic calprotectin values (Spearman's rho; r = 0.457 for ELISA, r = 0.473 for POC). A considerable range of ascitic calprotectin concentrations was detected by ELISA [median 0.43 μg/mL, interquartile range (IQR) 0.23-1.23 (range 0.10-14.93)] and POC [median 0.38 μg/mL, IQR 0.38-0.56 (range 0.38-13.31)]. Ascitic calprotectin levels were higher in samples with PMN > 250/μL, by both ELISA [median (IQR) 2.48 μg/mL (1.61-3.65) vs 0.10 μg/mL (0.10-0.36), P < 0.001] and POC [2.78 μg/mL (2.05-5.37) vs 0.38 μg/mL (0.38-0.41), P < 0.001]. The area under the receiver operating characteristics curve for identifying an elevated PMN count was 0.977 (95%CI: 0.933 to 0.995) for ELISA and 0.982 (95%CI: 0.942 to 0.997) for POC (P = 0.246 vs ELISA). Using the optimal cut-off value for ELISA (0.63 μg/mL), ascitic calprotectin had 94.8% sensitivity, 89.2% specificity, positive and negative likelihood ratios of 8.76 and 0.06 respectively, positive and negative predictive values of 60.0% and 99.0% respectively, and 90.0% overall accuracy. Using the optimal cut-off value for POC (0.51 μg/mL), the respective values were 100.0%, 84.7%, 6.53, 0.00, 52.8%, 100% and 87.7%. Correlation between ELISA and POC was excellent (r = 0.873, P < 0.001). The mean ± SD of the difference was -0.11 ± 0.48 μg/mL with limits of agreement of + 0.8 μg/mL (95%CI: 0.69 to 0.98) and -1.1 μg/mL (95%CI: -1.19 to -0.91). CONCLUSION: Ascitic calprotectin reliably predicts PMN count > 250/μL, which may prove useful in the diagnosis of SBP, especially with a readily available bedside testing device.Emanuel Burri Felix Schulte Jürgen Muser Rémy Meier Christoph Beglinger 2013World Journal of Gastroenterology2013,19,13:10
11Opposite Interplay Between the Canonical WNT/β-Catenin Pathway and PPAR Gamma: A Potential Therapeutic Target in Gliomas显示文摘In gliomas, the canonical Wingless/Int(WNT)/b-catenin pathway is increased while peroxisome proliferator-activated receptor gamma(PPAR-c) is downregulated.The two systems act in an opposite manner. This review focuses on the interplay between WNT/b-catenin signaling and PPAR-c and their metabolic implications as potential therapeutic target in gliomas. Activation of the WNT/bcatenin pathway stimulates the transcription of genes involved in proliferation, invasion, nucleotide synthesis,tumor growth, and angiogenesis. Activation of PPAR-c agonists inhibits various signaling pathways such as the JAK/STAT, WNT/b-catenin, and PI3 K/Akt pathways,which reduces tumor growth, cell proliferation, cell invasiveness, and angiogenesis. Nonsteroidal anti-inflammatory drugs, curcumin, antipsychotic drugs, adiponectin,and sulforaphane downregulate the WNT/b-catenin pathway through the upregulation of PPAR-c and thus appear to provide an interesting therapeutic approach for gliomas.Temozolomide(TMZ) is an antiangiogenic agent. The downstream action of this opposite interplay may explain the TMZ-resistance often reported in gliomas.AlexANDre Vallée Yves Lecarpentier Rémy Guillevin Jean-Noёl Vallée 2018Neuroscience Bulletin2018,34,3:7
12Intraductalpapillarymucinousneoplasmofthebileductwithgastricand duodenalfistulas显示文摘Intraductal papillary mucinous neoplasm (IPMN) of the bile duct is still rare and not yet understood despite of its increased incidence and similar clinicopathologic characteristics compared with IPMN of the pancreas. The fistula formation into other organs can occur in IPMN, especially the pancreatic type. To our knowl-edge, only two cases of IPMN of the bile duct with a choledochoduodenal fistula were reported and we have recently experienced a case of IPMN of the bile duct penetrating into two neighboring organs of the stom-ach and duodenum presenting with abdominal pain and jaundice. Endoscopy showed thick mucin extruding from two openings of the fistulas. Endoscopic suction of thick mucin using direct peroral cholangioscopy with ultra-slim endoscope through choledochoduodenal fis-tula was very difficult and ineffective because of very thick mucin and next endoscopic suction through the stent after prior insertion of biliary metal stent into cho-ledochogastric fistula also failed. Pathologic specimen obtained from the proximal portion of the choledocho-gastric fistula near left intrahepatic bile duct through the metal stent showed a low grade adenoma. The pa-tient declined the surgical treatment due to her old age and her abdominal pain with jaundice was improved af-ter percutaneous transhepatic biliary drainage with the irrigation of N-acetylcysteine three times daily for 10 d.Hong MY Yu DW Hong SG 2014World Journal of Gastrointestinal Endoscopy2014,6,7:7

14Rise and fall of anti-obesity drugs显示文摘Although it is not generally a life-threatening disease,obesity is becoming a major health problem worldwide.It can be controlled by means of drugs,and,consequently,these are required to be safe as well as effective.In this paper,we summarize the fate of various drugs that have been introduced for clinical use in the treatment of obesity.Fenfluramine and dexfenfluramine were withdrawn because of heart valve damage.Sibutramine suppresses appetite and increases heart rate and blood pressure.In the Sibutramine Cardiovascular OUTcomes trial,an increase in major adverse cardiovascular events prompted its withdrawal in Europe and the United States.Rimonabant is an endocannabinoid receptor antagonist that reduces body weight and ameliorates some cardiovascular risk factors.However,adverse psychiatric side effects led to its withdrawal as well.Orlistat is approved in Europe and the United States for the treatment of obesity,but its use is limited by gastrointestinal side-effects.Ephedrine and caffeine are natural ingredients in foods and supplements that may help the person to lose weight.In the light of several failed attempts,there is a clear need to develop drugs that are effective and safe in the long term in order to successfully combat the phenomenon of obesity.Bernard MY Cheung 2011World Journal of Diabetes2011,2,2:7

17Factors associated with irritable bowel syndrome symptoms in hemodialysis patients显示文摘AIM: To investigate clinical characteristics associated with the presence of irritable bowel syndrome (IBS) symptoms in hemodialysis (HD) patients.METHODS: This was a cross-sectional study. A questionnaire based on the Bowel Disease Questionnaire that records gastrointestinal symptoms was given to 294 patients in 4 dialysis centers. A total of 196 (67%) subjects returned the survey. A multivariable logistic regression model was used to identify factors significantly associated with IBS symptoms. RESULTS: Symptoms compatible with IBS were present in 27 (13.8%) subjects and independently associated with low post-dialysis serum potassium [OR = 0.258, 95% CI (0.075-0.891), P = 0.032], paracetamol use [OR = 3.159, 95% CI (1.214-8.220), P = 0.018], and Kidney Disease Quality of Life (KDQOL) cognitive function score [OR = 0.977, 95% CI (0.956-0.999), P = 0.042]. Univariate regressions were also performed and the reported significance is for multivariate analysis. No association was detected for age, gender, depressed mood, smoking (present or past), body mass index, albumin level, Kt/V, sodium preor post-dialysis level, change in potassium level during HD, proton pump inhibitor or H2 blocker use, aspirin use, residual diuresis, hepatitis B or C infection, diabetes mellitus, marital status and education level. CONCLUSION: This study examined potential risk factors for symptoms compatible with IBS in HD patients and identified an association with paracetamol use, post-dialysis potassium level and KDQOL-cognitive function score.Bartosz Fiderkiewicz Alicja Rydzewska-Rosoowska Micha Myliwiec Magdalena Birecka Bozenna Kaczanowska Grazyna Rydzewska Andrzej Rydzewski 2011World Journal of Gastroenterology2011,17,15:5
