| 1 | Long-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 Rsch Roland M Schmid Christian Prinz | 2007 | World Journal of Gastroenterology2007，13，9： | 23 |
| 2 | Endoscopic transpapillary brush cytology and forceps biopsy in patients with hilar cholangiocarcinoma显示文摘AIM: To evaluate the sensitivity of brush cytology and forceps biopsy in a homogeneous patient group with hilar cholangiocarcinoma.METHODS: Brush cytology and forceps biopsy were routinely performed in patients with suspected malignant biliary strictures. Fifty-eight consecutive patients undergoing endoscopic retrograde cholangio-pancreatography (ERCP) including forceps biopsy and brush cytology in patients with hilar cholangiocarcinoma between 1995-2005.RESULTS: Positive results for malignancy were obtained in 24/58 patients (41.4%) by brush cytology and in 31/58 patients (53.4%) by forceps biopsy. The combination of both techniques brush cytology and forceps biopsy resulted only in a minor increase in diagnostic sensitivity to 60.3% (35/58 patients). In 20/58 patients (34.5%), diagnosis were obtained by both positive cytology and positive histology, in 11/58 (19%) by positive histology (negative cytology) and only 4/58 patients (6.9%) were confirmed by positive cytology (negative histology).CONCLUSION: Brush cytology and forceps biopsy have only limited sensitivity for the diagnosis of malignant hilar tumors. In our eyes, additional diagnostic techniques should be evaluated and should become routine in patients with negative cytological and histological findings. | Andreas Weber Claus von Weyhern Falko Fend Jochen Schneider Bruno Neu Alexander Meining Hans Weidenbach Roland M Schmid Christian Prinz | 2008 | World Journal of Gastroenterology2008，14，7： | 17 |
| 3 | Short lessons in basic life support improve self-assurance in performing cardiopulmonary resuscitation显示文摘BACKGROUND:There are several reasons why resuscitation measures may lead to inferior results:difficulties in team building,delayed realization of the emergency and interruption of chest compression.This study investigated the outcome of a new form of in-hospital cardiopulmonary resuscitation(CPR) training with special focus on changes in self-assurance of potential helpers when faced with emergency situations.METHODS:Following a 12-month period of CPR training,questionnaires were distributed to participants and non-participants.Those non-participants who intended to undergo the training at a later date served as control group.RESULTS:The study showed that participants experienced a significant improvement in selfassurance,compared with their remembered self-assurance before the training.Their self-assurance also was significantly greater than that of the control group of non-participants.CONCLUSION:Short lessons in CPR have an impact on the self-assurance of medical and non-medical personnel. | Mario Kobras Sascha Langewand Christina Murr Christiane Neu Jeannette Schmid | 2016 | World Journal of Emergency Medicine2016，7，4： | 7 |

| 5 | Depicting the battle between nectarine and Monilinia laxa:the fruit developmental stage dictates the effectiveness of the host defenses and the pathogen’s infection strategies显示文摘Infections by the fungus Monilinia laxa,the main cause of brown rot in Europe,result in considerable losses of stone fruit.Herein,we present a comprehensive transcriptomic approach to unravel strategies deployed by nectarine fruit and M.laxa during their interaction.We used M.laxa-inoculated immature and mature fruit,which was resistant and susceptible to brown rot,respectively,to perform a dual RNA-Seq analysis.In immature fruit,host responses,pathogen biomass,and pathogen transcriptional activity peaked at 14–24 h post inoculation(hpi),at which point M.laxa appeared to switch its transcriptional response to either quiescence or death.Mature fruit experienced an exponential increase in host and pathogen activity beginning at 6 hpi.Functional analyses in both host and pathogen highlighted differences in stage-dependent strategies.For example,in immature fruit,M.laxa unsuccessfully employed carbohydrate-active enzymes(CAZymes)for penetration,which the fruit was able to combat with tightly regulated hormone responses and an oxidative burst that challenged the pathogen’s survival at later time points.In contrast,in mature fruit,M.laxa was more dependent on proteolytic effectors than CAZymes,and was able to invest in filamentous growth early during the interaction.Hormone analyses of mature fruit infected with M.laxa indicated that,while jasmonic acid activity was likely useful for defense,high ethylene activity may have promoted susceptibility through the induction of ripening processes.Lastly,we identified M.laxa genes that were highly induced in both quiescent and active infections and may serve as targets for control of brown rot. | Marta Balsells-Llauradó Christian J.Silva Josep Usall Núria Vall-llaura Sandra Serrano-Prieto Neus Teixidó Saskia D.Mesquida-Pesci Antonieta de Cal Barbara Blanco-Ulate Rosario Torres | 2020 | Horticulture Research2020，7，1： | 1 |

| 9 | Endoscopic stent therapy in patients with chronic pancreatitis:A 5-year follow-up study显示文摘AIM:This study analyzed clinical long-term outcomes after endoscopic therapy,including the incidence and treatment of relapse. METHODS:This study included 19 consecutive patients(12 male,7 female,median age 54 years)with obstructive chronic pancreatitis who were admitted to the 2nd Medical Department of the Technical University of Munich.All patients presented severe chronic pancreatitis(stageⅢ°)according to the Cambridge classification.The majority of the patients suffered intermittent pain attacks.6 of 19 patients had strictures of the pancreatic duct;13 of 19 patients had strictures and stones.The first endoscopic retrograde pancreatography(ERP)included an endoscopic sphincterotomy, dilatation of the pancreatic duct,and stent placement.The first control ERP was performed 4 wk after the initial intervention,and the subsequent control ERP was performed after 3 mo to re-evaluate the clinical and morphological conditions.Clinical follow-up was performed annually to document the course of pain and the management of relapse.The course of pain was assessed by a pain scale from 0 to 10.The date and choice of the therapeutic procedure were documented in case of relapse. RESULTS:Initial endoscopic intervention was successfully completed in 17 of 19 patients.All 17 patients reported partial or complete pain relief after endoscopic intervention.Endoscopic therapy failed in 2 patients. Both patients were excluded from further analysis.One failed patient underwent surgery,and the other patient was treated conservatively with pain medication.Seventeen of 19 patients were followed after the successful completion of endoscopic stent therapy.Three of 17 patients were lost to follow-up.One patient was not avail-able for interviews after the 1st year of follow-up.Two patients died during the 3rd year of follow-up.In both patients chronic pancreatitis was excluded as the cause of death.One patient died of myocardial infarction, and one patient succumbed to pneumonia.All three patients were excluded from follow-up analysis.Followup was successfully completed in 14 of 17 patients.4 patients at time point 3,2 patients at time point 4,3 patients at time point 5 and 2 patients at time point 6 and time point 7 used continuous pain medication after endoscopic therapy.No relapse occurred in 57%(8/14) of patients.All 8 patients exhibited significantly reduced or no pain complaints during the 5-year follow-up.Seven of 8 patients were completely pain free 5 years after endoscopic therapy.Only 1 patient reported continuous moderate pain.In contrast,7 relapses occurred in 6 of the 14 patients.Two relapses were observed during the 1st year,2 relapses occurred during the 2nd year,one relapse was observed during the 3rd year,one relapse occurred during the 4th year,and one relapse occurred during the 5th follow-up year.Four of these six patients received conservative treatment with endoscopic therapy or analgesics.Relapse was conservatively treated using repeated stent therapy in 2 patients.Analgesic treatment was successful in the other 2 patients. CONCLUSION:57%of patients exhibited long-term benefits after endoscopic therapy.Therefore,endoscopic therapy should be the treatment of choice in patients being inoperable or refusing surgical treatment. | Andreas Weber Jochen Schneider Bruno Neu Alexander Meining Peter Born Stefan von Delius Monther Bajbouj Roland M Schmid Hana Algül Christian Prinz | 2013 | World Journal of Gastroenterology2013，19，5： | 1 |

| 11 | Self-assembly as a tool to study microscale curvature and strain-dependent magnetic properties显示文摘The extension of 2D ferromagnetic structures into 3D curved geometry enables to tune its magnetic properties such as uniaxial magnetic anisotropy.Tuning the anisotropy with strain and curvature has become a promising ingredient in modern electronics,such as flexible and stretchable magnetoelectronic devices,impedance-based field sensors,and strain gauges,however,has been limited to extended thin films and to only moderate bending.By applying a self-assembly rolling technique using a polymeric platform,we provide a template that allows homogeneous and controlled bending of a functional layer adhered to it,irrespective of its shape and size.This is an intriguing possibility to tailor the sign and magnitude of the surface strain of integrated,micronsized devices.In this article,the impact of strain and curvature on the magnetic ground state and anisotropy is quantified for thinfilm Permalloy micro-scale structures,fabricated on the surface of the tubular architectures,using solely electrical measurements. | Balram Singh Jorge A.Otálora Tong H.Kang Ivan Soldatov Dmitriy D.Karnaushenko Christian Becker Rudolf Schäfer Daniil Karnaushenko Volker Neu Oliver G.Schmidt | 2022 | npj Flexible Electronics2022，6，1： | 0 |
| 12 | A new peroral mother-baby endoscope system for biliary tract disorders显示文摘AIM: To investigate a new mother-baby system, consisting of a peroral cholangioscope and a duodenoscope in patients regarding its feasibility. METHODS: In the study period from January 2007 to February 2010, 76 consecutive patients(33 men, 43 women; mean age 63 years old) were included in this pilot series. Endoluminal images and biopsies were obtained from 55 patients with indeterminate strictures, while 21 patients had fixed filling defects. The diagnostic accuracy of peroral cholangioscopy(POCS) in the visualization of strictures and tissue sampling was evaluated, and therapeutic success was monitored. Followup was performed over at least 9 mo. RESULTS: A total of 55 patients had indeterminate strictures. Using the criteria 'circular stenosis' and 'irregular surface or margins', POCS correctly described 27 out of 28 malignant biliary strictures and 25 out of 27 benign lesions(sensitivity, 96.4%; specificity, 92.6%, diagnostic accuracy 94.5%). Visually targeted forceps biopsies were performed in 55 patients. Tissue sampling during POCS revealed malignancy in 18 of 28 cases(sensitivity: 64.3%). In 21 patients with fixed filling defects, 10 patients with bile duct stones were successfully treated with conventional stone removal. Nine patients with difficult stones(5 giant stones and 4 intrahepatic stones) were treated with visually guided laser lithotripsy. Two patients in the group with unclear fixed filling defects had bile duct adenoma or papillary tumors and were surgically treated. CONCLUSION: The new 95 cm POCS allows for accurate discrimination of strictures and fixed filling defects in the biliary tree, provides improved sensitivity of endoscopically guided biopsies and permits therapeutic approaches for difficult intrahepatic stones. | Christian Prinz Andreas Weber Stefanie Goecke Bruno Neu Alexander Meining Eckart Frimberger | 2014 | World Journal of Gastrointestinal Endoscopy2014，6，1： | 0 |
