2Long-term outcome and prognostic factors of patients with hilar cholangiocarcinoma显示文摘AIM: To evaluate the long-term outcome and prognostic factors of patients with hilar cholangiocarinoma. METHODS: Ninety-six consecutive patients underwent treatment for malignant hilar bile duct tumors during 1995–2005. Of the 96 patients, 20 were initially treated with surgery (n = 2 R0 / n = 18 R1). In non-operated patients, data analysis was performed retrospectively. RESULTS: Among the 96 patients, 76 were treated with endoscopic transpapillary (ERC, n = 45) and/or percutaneous transhepatic biliary drainage (PTBD, n = 31). The mean survival time of these 76 patients undergoing palliative endoscopic and/or percutaneous drainage was 359 ± 296 d. The mean survival time of patients with initial bilirubin levels > 10 mg/dL was significantly lower (P < 0.001) than patients with bilirubin levels < 10 mg/dL. The mean survival time of patients with Bismuth stage Ⅱ (n = 8), Ⅲ (n = 28) and Ⅳ (n = 40) was 496 ± 300 d, 441 ± 385 d and 274 ± 218 d, respectively. Thus, patients with advanced Bismuth stage showed a reduced mean survival time, but the difference was not significant. The type of biliary drainage had no significant beneficial effect on the mean survival time (ERC vs PTBD, P = 0.806). CONCLUSION: Initial bilirubin level is a significant prognostic factor for survival of patients. In contrast, age, tumor stage according to the Bismuth-Corlette classification, and types of intervention are not significant prognostic parameters for survival. Palliative treatment with endoscopic or percutaneous biliary drainage is still suboptimal, new diagnostic and therapeutic tools need to be evaluated.Andreas Weber Sonja Landrock Jochen Schneider Manfred Stangl Bruno Neu Peter Born Meinhard Classen Thomas Rsch Roland M Schmid Christian Prinz 2007World Journal of Gastroenterology2007,13,9:23

4Genetics of hepatocellular carcinoma显示文摘The completely assembled human genome has made it possible for modern medicine to step into an era rich in genetic information and high-throughput genomic analysis. These novel and readily available genetic resources and analytical tools may be the key to unravel the molecular basis of hepatocellular carcinoma (HCC). Moreover, since an efficient treatment for this disease is lacking, further understanding of the genetic background of HCC will be crucial in order to develop new therapies aimed at selected targets. We report on the current status and recent developments in HCC genetics. Special emphasis is given to the genetics and regulation of major signalling pathways involved in HCC such as p53, Wnt- signalling, TGFβ, Ras, and Rb pathways. Furthermore, we describe the influence of chromosomal aberrations as well as of DNA methylation. Finally, we report on the rapidly developing field of genomic expression profiling in HCC, mainly by microarray analysis.Andreas Teufel Frank Staib Stephan Kanzler Arndt Weinmann Henning Schulze-Bergkamen Peter R Galle 2007World Journal of Gastroenterology2007,13,16:21
5Update on autoimmune hepatitis显示文摘Autoimmune hepatitis (AIH) is a necroinflammatory liver disease of unknown etiology that occurs in children and adults of all ages. Characteristics are its autoimmune features,hyperglobulinemia (IgG),and the presence of circulating autoantibodies,as well as a response to immunosuppressant drugs. Current treatment consists of prednisone and azathioprine and in most patients this disease has become very treatable. Over the past 2 years,a couple of new insights into the genetic aspects,clinical course and treatment of AIH have been reported,which will be the focus of this review. In particular,we concentrate on genome-wide microsatellite analysis,a novel mouse model of AIH,the evaluation of a large AIH cohort for overlap syndromes,suggested novel criteria for the diagnosis of AIH,and the latest studies on treatment of AIH with budenoside and mycophenolate mofetil.Andreas Teufel Peter R Galle Stephan Kanzler 2009World Journal of Gastroenterology2009,15,9:17
6卒中相关性肺炎的诊断卒中肺炎共识小组的推荐意见显示文摘背景和目的下呼吸道感染常并发于卒中并对转归造成不利影响。对于并发于卒中的下呼吸道感染性疾病,目前尚无公认的专业术语或诊断金标准,这导致临床诊疗和研究受到影响。本共识旨在提出急性卒中并发下呼吸道感染的标准化术语和可操作性诊断标准。方法对多个文献数据库进行系统检索,经过证据回顾和2轮讨论,最后于2014年9月在英国曼彻斯特召开共识会议,经75%以上共识小组成员达成一致意见后形成共识。结果达成的共识如下:(1)推荐使用卒中相关性肺炎(stroke-associated pneumonia, SAP )作为卒中发病后7 d内发生的下呼吸道感染性疾病的专业术语。(2)提议对 SAP 使用经过改良的美国疾病控制预防中心(Centers for Disease Control and Prevention, CDC)诊断标准:①很可能的 SAP:符合 CDC 诊断标准,但复查或动态监测胸部 X 片仍缺乏典型改变;②确诊的 SAP:符合 CDC 诊断标准,且胸部 X 片有典型改变。(3)关于白细胞计数或 C反应蛋白在 SAP 诊断中的作用证据有限。(4)其他生物学标记物(如降钙素原)的证据不足。结论提议根据 CDC 诊断标准对 SAP 的术语和诊断制定可操作性的共识标准,需要在卒中患者中进行前瞻性研究来确定其信度、效度以及对医生行为(包括抗生素选择)和临床转归的影响。Craig J.

7Proposal of an ultrasonographic classification for hepatic alveolar echinococcosis: Echinococcosis multilocularis Ulm classification-ultrasound显示文摘AIM: To establish an ultrasonographic classification based on a large sample of patients with confirmed hepatic alveolar echinococcosis(AE).METHODS: Clinical data and ultrasonography(US) findings of 185 patients(100 males; 85 females; mean age at diagnosis: 51.4 ± 17.6 years; mean age at time of US examination: 58.7 ± 18.2 years) were retrospectively reviewed with respect to the US morphology of hepatic AE lesions. The sonomorphological findings were grouped according to a five-part classification scheme.RESULTS: Application of the new classification resulted in the following distribution of sonomorphological patterns among the patients examined: hailstorm(54.1%); pseudocystic(13.5%); ossification(13.0%); hemangioma-like(8.1%); and metastasis-like(6.5%). Only 4.9% of lesions could not be assigned to a sonomorphological pattern.CONCLUSION: The sonomorphological classification proposed in the present study facilitates the diagnosis,interpretation and comparison of hepatic alveolar echinococcosis in routine practice and in the context of scientific studies.Wolfgang Kratzer Beate Gruener Tanja EM Kaltenbach Sarina Ansari-Bitzenberger Peter Kern Michael Fuchs Richard A Mason Thomas FE Barth Mark M Haenle Andreas Hillenbrand Suemeyra Oeztuerk Tilmann Graeter 2015World Journal of Gastroenterology2015,21,43:16

9Pro12Ala polymorphism of the peroxisome proliferator-activated receptor γ2 in patients with fatty liver diseases显示文摘AIM:To test the occurrence of the Pro12Ala mutation of the peroxisome proliferator-activated receptor-γ (PPARγ)2-gene in patients with non-alcoholic fatty liver disease (NAFLD) or alcoholic fatty liver disease (AFLD).METHODS:DNA from a total of 622 specimens including 259 blood samples of healthy blood donors and 363 histologically categorized liver biopsies of patients with NAFLD (n=263) and AFLD (n=100) were analyzed by Real-time polymerase chain reaction using allele-specific probes.RESULTS:In the NAFLD and the AFLD collective,3% of the patients showed homozygous occurrence of the Ala12 PPARγ2-allele,differing from only 1.5% cases in the healthy population.In NAFLD patients,a high incidence of the Ala12 mutant was not associated with the progression of fatty liver disease.However,we observed a significantly higher risk (odds ratio=2.50,CI:1.05-5.90,P=0.028) in AFLD patients carrying the mutated Ala12 allele to develop inflammatory alterations.The linkage of the malfunctioning Ala12-positive PPARγ2 isoform to an increased risk in patients with AFLD to develop severe steatohepatitis and fibrosis indicates a more prominent anti-inflammatory impact of PPARγ2 in progression of AFLD than of NAFLD.CONCLUSION:In AFLD patients,the Pro12Ala single nuclear polymorphism should be studied more extensively in order to serve as a novel candidate in biomarker screening for improved prognosis.Johannes W Rey Andrea Noetel Aline Hardt Ali Canbay Hakan Alakus Axel zur Hausen Hans Peter Dienes Uta Drebber Margarete Odenthal 2010World Journal of Gastroenterology2010,16,46:11
10Capecitabine and irinotecan with and without bevacizumab for advanced colorectal cancer patients显示文摘AIM:To investigate the efficacy and safety of capecitabine plus irinotecan±bevacizumab in advanced or metastatic colorectal cancer patients. METHODS:Forty six patients with previously untreated,locally-advanced or metastatic colorectal cancer(mCRC) were recruited between 2001-2006 in a prospective open-label phaseⅡtrial,in German community-based outpatient clinics.Patients received a standard capecitabine plus irinotecan(CAPIRI) or CAPIRI plus bevacizumab(CAPIRI-BEV) regimen every 3 wk. Dose reductions were mandatory from the first cycle in cases of>grade 2 toxicity.The treatment choice of bevacizumab was at the discretion of the physician.Theprimary endpoints were response and toxicity and secondary endpoints included progression-free survival and overall survival. RESULTS:In the CAPIRI group vs the CAPRI-Bev group there were more female than male patients(47% vs 24%) ,and more patients had colon as the primary tumor site(58.8%vs 48.2%) with fewer patients having sigmoid colon as primary tumor site(5.9%vs 20.7%) .Grade 3/4 toxicity was higher with CAPIRI than CAPIRI-Bev:82%vs 58.6%.Partial response rates were 29.4%and 34.5%,and tumor control rates were 70.6%and 75.9%,respectively.No complete responses were observed.The median progression-free survival was 11.4 mo and 12.8 mo for CAPIRI and CAPIRI-Bev,respectively.The median overall survival for CAPIRI was 15 mo(458 d) and for CAPIRI-Bev 24 mo(733 d) .These differences were not statistically different.In the CAPIRI-Bev,group,two patients underwent a full secondary tumor resection after treatment,whereas in the CAPIRI group no cases underwent this procedure. CONCLUSION:Both regimens were well tolerated and offered effective tumor growth control in this outpatient setting.Severe gastrointestinal toxicities and thromboembolic events were rare and if observed were never fatal.Markus Moehler Martin F Sprinzl Murad Abdelfattah Carl C Schimanski Bernd Adami Werner Godderz Klaus Majer Dimitri Flieger Andreas Teufel Juergen Siebler Thomas Hoehler Peter R Galle Stephan Kanzler 2009World Journal of Gastroenterology2009,15,4:10
11Breath and string test: A diagnostic package for the identification of treatment failure and antibiotic resistance of Helicobacter pylori without the necessity of upper gastrointestinal endoscopy显示文摘AIM: Helicobacter pylori ( H pylofi) resistance after failed eradication has a major impact on the outcome of a further treatment regimen. The aim of this study was to assess the validity of a non-invasive strategy using the 13C-urea breath test (UBT) and the gastric string test in identifying post-treatment resistance of Hpylori.METHODS: The UBT was routinely performed 4 to 6 wk after H pylorieradication therapy. Forty-two patients (24 females, 18 males, mean age 48 years) with a positive UBT were included in the study. A gastric string test using a capsule containing a 90 cm-long nylon fiber was performed.Before the capsule was swallowed, the free end of the string was taped to the cheek. After one hour in the stomach, the string was withdrawn. The distal 20 cm of the string was inoculated onto an agar plate and processed under microaerophilic conditions. Following the string test, upper gastrointestinal endoscopy was performed to obtain gastric biopsies for conventional culture.RESULTS: H pyloriwas successfully cultured from the gastric string in 34 patients (81%), but not in 5 patients due to contamination with oropharyngeal flora. Hpyloriwas cultured from the gastric biopsies obtained at endoscopy in 39 patients (93%).CONCLUSION: The UBT followed by the gastric string test in the case of treatment failure is a valid diagnostic strategy with the aim of determining the post-therapeutic antibiotic resistance of Hpyloriwith little inconvenience to the patient.Upper GI-endoscopy can be avoided in several cases by applying consequently this diagnostic package.Andreas Leodolter Kathlen Wolle Ulrike von Arnim Stefan Kahl Gerhard Treiber Matthias P.Ebert Ulrich Peitz Peter Malfertheiner 2005World Journal of Gastroenterology2005,11,4:10
12Proposal of a computed tomography classification for hepatic alveolar echinococcosis显示文摘AIM: To establish a computed tomography(CT)-morphological classification for hepatic alveolar echinococcosis was the aim of the study. METHODS: The CT morphology of hepatic lesions in 228 patients with confirmed alveolar echinococcosis(AE) drawn from the Echinococcus Databank of the University Hospital of Ulm was reviewed retrospectively. For this reason, CT datasets of combined positron emission tomography(PET)-CT examinations were evaluated. The diagnosis of AE was made in patientswith unequivocal seropositivity; positive histological findings following diagnostic puncture or partial resection of the liver; and/or findings typical for AE at either ultrasonography, CT, magnetic resonance imaging or PET-CT. The CT-morphological findings were grouped into the new classification scheme.RESULTS: Within the classification a lesion was dedicated to one out of five 'primary morphologies' as well as to one out of six 'patterns of calcification'. 'primary morphology' and 'pattern of calcification' are primarily focussed on separately from each other and combined, whereas the 'primary morphology' V is not further characterized by a 'pattern of calcification'. Based on the five primary morphologies, further descriptive sub-criteria were appended to types Ⅰ-Ⅲ. An analysis of the calcification pattern in relation to the primary morphology revealed the exclusive association of the central calcification with type Ⅳ primary morphology. Similarly, certain calcification patterns exhibited a clear predominance for other primary morphologies, which underscores the delimitation of the individual primary morphological types from each other. These relationships in terms of calcification patterns extend into the primary morphological sub-criteria, demonstrating the clear subordination of those criteria.CONCLUSION: The proposed CT-morphological classification(EMUC-CT) is intended to facilitate the recognition and interpretation of lesions in hepatic alveolar echinococcosis. This could help to interpret different clinical courses better and shall assist in the context of scientific studies to improve the comparability of CT findings.Tilmann Graeter Wolfgang Kratzer Suemeyra Oeztuerk Mark Martin Haenle Richard Andrew Mason Andreas Hillenbrand Thomas Kull Thomas F Barth Peter Kern Beate Gruener 2016World Journal of Gastroenterology2016,22,13:10
13Presepsin teardown- pitfalls of biomarkers in the diagnosis and prognosis of bacterial infection in cirrhosis显示文摘AIM To evaluate the diagnostic and prognostic value of presepsin in cirrhosis-associated bacterial infections. METHODS Two hundred and sixteen patients with cirrhosis were enrolled. At admission, the presence of bacterial infections and level of plasma presepsin, serum C-reactive protein(CRP) and procalcitonin(PCT) were evaluated. Patients were followed for three months to assess the possible association between presepsin level and short-term mortality.RESULTS Present 34.7 of patients had bacterial infection. Presepsin levels were significantly higher in patients with infection than without(median, 1002 pg/m L vs 477 pg/m L, P < 0.001), increasing with the severity of infection [organ failure(OF): Yes vs No, 2358 pg/m L vs 710 pg/m L, P < 0.001]. Diagnostic accuracy of presepsin for severe infections was similar to PCT and superior to CRP(AUC-ROC: 0.85, 0.85 and 0.66, respectively, P = NS for presepsin vs PCT and P < 0.01 for presepsin vs CRP). At the optimal cut-off value of presepsin > 1206 pg/m L sensitivity, specificity, positive predictive values and negative predictive values were as follows: 87.5%, 74.5%, 61.8% and 92.7%. The accuracy of presepsin, however, decreased in advanced stage of the disease or in the presence of renal failure, most probably because of the significantly elevated presepsin levels in non-infected patients. 28-d mortality rate was higher among patients with > 1277 pg/m L compared to those with ≤ 1277 pg/m L(46.9% vs 11.6%, P < 0.001). In a binary logistic regression analysis, however, only PCT(OR = 1.81, 95%CI: 1.09-3.01, P = 0.022) but neither presepsin nor CRP were independent risk factor for 28-d mortality after adjusting with MELD score and leukocyte count.CONCLUSION Presepsin is a valuable new biomarker for defining severe infections in cirrhosis, proving same efficacy as PCT. However, it is not a useful marker of short-term mortality.Maria Papp Tamas Tornai Zsuzsanna Vitalis Istvan Tornai David Tornai Tamas Dinya Andrea Sumegi Peter Antal-Szalmas 2016World Journal of Gastroenterology2016,22,41:9

15Matched-pair analysis of postoperative morbidity and mortality for pancreaticogastrostomy and pancreaticojejunostomy using mattress sutures in soft pancreatic tissue remnants显示文摘BACKGROUND:After pancreaticoduodenectomy,the incidence of postoperative pancreatic fistula remains high,especially in patients with 'soft' pancreatic tissue remnants.No 'gold standard' surgical technique for pancreaticoenteric anastomosis has been established.This study aimed to compare the postoperative morbidity and mortality of pancreaticogastrostomy and pancreaticojejunostomy for 'soft' pancreatic tissue remnants using modified mattress sutures.METHODS:Seventy-five patients who had undergone pancreaticogastrostomy and 75 who had undergone pancreaticojejunostomy after pancreaticoduodenectomy between 2002 and 2008 were retrospectively compared using matched-pair analysis.A modified mattress suture technique was used for the pancreaticoenteric anastomosis.Patients with an underlying 'hard' pancreatic tissue remnant,as in chronic pancreatitis,were excluded.Both groups were homogeneous for age,gender,and underlying disease.Postoperative morbidity,mortality,and preoperative and operative data were analyzed.RESULTS:There were no significant differences between the groups for the incidence of postoperative pancreatic fistula (10.7% in both).Postoperative morbidity and mortality,median operation time,median length of hospital stay,intraoperative blood loss,and the amount of intraoperatively transfused erythrocyte concentrates also did not significantly differ between the groups.Patient age >65 years (P=0.017),operation time >350minutes (P=0.001),and intraoperative transfusion of erythrocyte concentrates (P=0.038) were identified as risk factors for postoperative morbidity.CONCLUSIONS:Our results showed no significant differences between the groups in the pancreaticogastrostomy and pancreaticojejunostomy anastomosis techniques using mattress sutures for 'soft' pancreatic tissue remnants.In our experience,the mattress sutures are safe and simple to use,and pancreaticogastrostomy in particular is feasible and easy to learn,with good endoscopic accessibility to the anastomosis region.However,the location of the anastomosis and the surgical technique need to be individually evaluated to further reduce the incidence of postoperative pancreatic fistula.Fritz Klein Marcus Bahra Matthias Glanemann Wladimir Faber Peter Warnick Andreas Andreou Safak Gül Dietmar Jacob 2012Hepatobiliary & Pancreatic Diseases International2012,11,1:9
16Identification of CD13,CD107a,and CD164 as novel basophil-activation markers and dissection of two response patterns in time kinetics of IgE-de-pendent upregulation显示文摘Using two-colour flow cytometry >200 antibodies submitted to the 8th International Workshop of Human Leukocyte Differentiation Antigens (HLDA8) have been analyzed for their reactivity with resting and activated CD203c+ basophils. Four antibodies either non-reactive or weakly reactive with resting basophils exhibited an increased reactivity with basophils activated by anti-IgE-mediated cross-linking of the high affinity IgE receptor (FcεRI). These include antibod- ies against CD164 (WS-80160, clone N6B6 and WS-80162, clone 67D2), as well as two reagents with previously unknown specificities that were identified as CD13 (WS-80274, clone A8) and CD107a (WS-80280, clone E63-880). The activation patterns followed either the “CD203c-like” or “CD63-like” activation profile. The CD203c profile is characterized by a rapid and significant upregulation (of CD13, CD164, and CD203c), reaching maximum levels after 5- 15 min of stimulation. The phosphoinositide-3-kinase (PI3K)-specific inhibitor wortmannin inhibited the upregulation of these markers whereas 12-O-tetradecanoyl-phorbol-13-acetate (TPA) induced a rapid and FcεRI-independent upregulation within 1-2 min. In the CD63 profile, maximum upregulation (of CD63 and CD107a) was detected only after 20-40 min, and upregulation by TPA reached maximum levels after 60 min. In summary, our data identify CD13, CD107a, and CD164 as novel basophil-activation antigens. Based on time kinetics of upregulation, we hypothesize that molecules of the “CD203c group” and the “CD63 group” are linked to two different mechanisms of basophil activation.Florian HENNERSDORF Stefan FLORIAN Andreas JAKOB Katharina BAUMGRTNER Karoline SONNECK Alfred NORDHEIM Tilo BIEDERMANN Peter VALENT Hans-Jrg BüHRING 2005Cell Research2005,15,5:9
17Silicon and silicon nitride photonic circuits for spectroscopic sensing on-a-chip [Invited]显示文摘There is a rapidly growing demand to use silicon and silicon nitride(Si3N4) integrated photonics for sensing applications, ranging from refractive index to spectroscopic sensing. By making use of advanced CMOS technology,complex miniaturized circuits can be easily realized on a large scale and at a low cost covering visible to mid-IR wavelengths. In this paper we present our recent work on the development of silicon and Si3N4-based photonic integrated circuits for various spectroscopic sensing applications. We report our findings on waveguide-based absorption, and Raman and surface enhanced Raman spectroscopy. Finally we report on-chip spectrometers and on-chip broadband light sources covering very near-IR to mid-IR wavelengths to realize fully integrated spectroscopic systems on a chip.Ananth Z.Subramanian Eva Ryckeboer Ashim Dhakal Frédéric Peyskens Aditya Malik Bart Kuyken Haolan Zhao Shibnath Pathak Alfonso Ruocco Andreas De Groote Pieter Wuytens Daan Martens Francois Leo Weiqiang Xie Utsav Deepak Dave Muhammad Muneeb Pol Van Dorpe Joris Van Campenhout Wim Bogaerts Peter Bienstman Nicolas Le Thomas Dries Van Thourhout Zeger Hens Gunther Roelkens Roel Baets 2015Photonics Research2015,3,5:7
