| 1 | MicroRNAs as possible biomarkers for diagnosis and prognosis of hepatitis b- and c-related-hepatocellularcarcinoma显示文摘Aim of the present review is to summarize the current knowledge about the potential relationship between mi RNAs and hepatitis B virus(HBV)-hepatitis C virus(HCV) related liver diseases. A systematic computerbased search of published articles, according to the Preferred Reporting Items for Systematic reviews and Meta-Analysis Statement, was performed to identify relevant studies on usefulness of serum/plasma/urine mi RNAs, as noninvasive biomarkers for early detection of HBV and HCV-induced hepatocellular carcinoma(HCC) development, as well as for its prognostic evaluation. The used Medical Subject Headings terms and keywords were: 'HBV', 'HCV', 'hepatocellular carcinoma', 'micro RNAs', 'mi RNAs', 'diagnosis', 'prognosis', 'therapy', 'treatment'. Some serum/plasma mi RNAs, including mi R-21, mi R-122, mi-125a/b, mi R-199a/b, mi R-221, mi R-222, mi R-223, mi R-224 might serve as biomarkers for early diagnosis/prognosis of HCC, but, to date, not definitive results or well-defined panels of mi RNAs have been obtained. More well-designed studies, focusing on populations of different geographical areas and involving larger series of patients, should be carried out to improve our knowledge on the potential role of mi RNAs for HCC early detection and prognosis. | Sirio Fiorino Maria Letizia Bacchi-Reggiani Michela Visani Giorgia Acquaviva Adele Fornelli Michele Masetti Andrea Tura Fabio Grizzi Matteo Zanello Laura Mastrangelo Raffaele Lombardi Luca Di Tommaso Arrigo Bondi Sergio Sabbatani Andrea Domanico Carlo Fabbri Paolo Leandri Annalisa Pession Elio Jovine Dario de Biase | 2016 | World Journal of Gastroenterology2016，22，15： | 25 |
| 2 | Endoscopic ultrasound-guided treatments: Are we getting evidence based- a systematic review显示文摘The continued need to develop less invasive alternatives to surgical and radiologic interventions has driven the development of endoscopic ultrasound(EUS)-guided treatments.These include EUS-guided drainage of pancreatic fluid collections,EUS-guided necrosectomy,EUS-guided cholangiography and biliary drainage,EUSguided pancreatography and pancreatic duct drainage,EUS-guided gallbladder drainage,EUS-guided drainage of abdominal and pelvic fluid collections,EUS-guided celiac plexus block and celiac plexus neurolysis,EUSguided pancreatic cyst ablation,EUS-guided vascular interventions,EUS-guided delivery of antitumoral agents and EUS-guided fiducial placement and brachytherapy.However these procedures are technically challenging and require expertise in both EUS and interventional endoscopy,such as endoscopic retrograde cholangiopancreatography and gastrointestinal stenting.We undertook a systematic review to record the entire body of literature accumulated over the past 2decades on EUS-guided interventions with the objective of performing a critical appraisal of published articles,based on the classification of studies according to levels of evidence,in order to assess the scientific progress made in this field. | Carlo Fabbri Carmelo Luigiano Andrea Lisotti Vincenzo Cennamo Clara Virgilio Giancarlo Caletti Pietro Fusaroli | 2014 | World Journal of Gastroenterology2014，20，26： | 18 |
| 3 | 中国明代木质古建西安鼓楼彩绘的分析研究显示文摘鉴于有关中国木质古建彩绘材料及技术的研究报道较少,本工作通过光学显微镜、扫描电镜能谱(SEMEDX)、X射线衍射及气相色谱质谱(GC/MS)分析方法,对建于公元1380年的中国西安明代鼓楼木建表面彩绘样品进行了科学检测研究,分析了其中的无机材料组成及彩绘所用粘合剂,并收集了所涉及到的相关历史资料。分析结果表明,木建表面彩绘的材料组成和制作技术与历史调查获得的信息完全吻合。地仗层主要由粘土、石灰、干性油(桐油)及纤维织物组成,且地仗层保持最初的原材料。颜料分析结果显示,尽管修复时所使用的粘合剂与最初建造时的粘合剂完全相同,但目前彩绘的颜料即有原来使用的材料,也有十八世纪修复时所使用的材料。 | Mazzeo R Cam D Chiavari G Fabbri D 和玲 Prati S | 2005 | 文物保护与考古科学2005，17，2： | 14 |
| 4 | 胰腺的液体集合的内视镜的指导超声的排水显示文摘 Pancreatic fluid collections (PFCs) develop secondary to either fluid leakage or liquefaction of pancreatic necrosis following acute pancreatitis, chronic pancreatitis, surgery or abdominal trauma. Pancreatic fluid collections include acute fluid collections, acute and chronic pancreatic pseudocysts, pancreatic abscesses and pancreatic necrosis. Before the introduction of linear endoscopic ultrasound (EUS) in the 1990s and the subsequent development of endoscopic ultrasound-guided drainage (EUS-GD) procedures, the available options for drainage in symptomatic PFCs included surgical drainage, percutaneous drainage using radiological guidance and conventional endoscopic transmural drainage. In recent years, it has gradually been recog-nized that, due to its lower morbidity rate compared to the surgical and percutaneous approaches, endoscopic treatment may be the preferred first-line approach for managing symptomatic PFCs. Endoscopic ultrasound-guided drainage has the following advantages, when compared to other alternatives such as surgical, per-cutaneous and non-EUS-guided endoscopic drainage.EUS-GD is less invasive than surgery and therefore does not require general anesthesia. The morbidity rate is lower, recovery is faster and the costs are lower. EUS-GD can avoid local complications related to per-cutaneous drainage. Because the endoscope is placed adjacent to the fluid collection, it can have direct ac-cess to the fluid cavity, unlike percutaneous drainage which traverses the abdominal wall. Complications such as bleeding, inadvertent puncture of adjacent viscera, secondary infection and prolonged periods of drainage with resultant pancreatico-cutaneous fistulae may be avoided. The only difference between EUS and non-EUS drainage is the initial step, namely, gaining access to the pancreatic fluid collection. All the sub-sequent steps are similar, i.e., insertion of guide-wires with fluoroscopic guidance, balloon dilatation of the cystogastrostomy and insertion of transmural stents or nasocystic catheters. With the introduction of the EUS-scope equipped with a large operative channel which permits drainage of the PFCs in 'one step', EUS-GD has been increasingly carried out in many tertiary care centers and has expanded the safety and efficacy of this modality, allowing access to and drainage of overly challenging fluid collections. However, the nature of the PFCs determines the outcome of this procedure. The technique and review of current literature regarding EUS-GD of PFCs will be discussed. | Carlo Fabbri Carmelo Luigiano Antonella Maimone Anna Maria Polifemo Ⅰlaria Tarantino Vincenzo Cennamo | 2012 | World Journal of Gastrointestinal Endoscopy2012，4，11： | 13 |
| 5 | Is the pancreas affected in patients with septic shock?——a prospective study显示文摘BACKGROUND:Hyperamylasemia can be observed anecdotally during the course of severe sepsis or septic shock.This study aimed to investigate the possibility of pancreatic involvement in patients with septic shock using serum pancreatic enzyme determinations and imaging techniques in 21 consecutive patients with septic shock and 21 healthy subjects as controls. METHODS:The serum activity of pancreatic amylase and lipase was assayed initially in all subjects and 24 and 48 hours after the initial observation in the 21 patients with septic shock All patients also underwent radiological examination to detect pancreatic abnormalities. RESULTS:The serum activity of pancreatic amylase was significantly higher in the 21 patients with septic shock than in the 21 control subjects during the study period while the serum activity of lipase was similar to that of the control subjects.Amylase and lipase serum activity did not significantly changed throughout the study period in the 21 patients with septic shock.None of the patients with pancreatic hyperenzymemia had clinical signs or morphological alterations compatible with acute pancreatitis CONCLUSION:The presence of pancreatic hyperenzymemia in septic shock patients is not a biochemical manifestation of acute pancreatic damage,and the management of these patients should be dependent on the clinical situation and not merely the biochemical results. | Raffaele Pezzilli Alessandra Barassi Andrea Imbrogno Dario Fabbri Antonina Pigna Antonio M.Morselli-Labate Roberto Corinaldesi Gianvico Melzi d'Eril | 2011 | Hepatobiliary & Pancreatic Diseases International2011，10，2： | 11 |
| 6 | Asthma and gastroesophageal reflux disease: Effect of long-term pantoprazole therapy显示文摘AIM: To define the prevalence of gastroesophageal reflux disease (GERD) in mild persistent asthma and to value the effect of pantoprazole therapy on asthmatic symptoms.METHODS: Seven of thirty-four asthmatic patients without GERD served as the non-GERD control group.Twenty-seven of thirty-four asthmatic patients had GERD (7/27 also had erosive esophagitis, sixteen of them presented GERD symptoms. An upper gastrointestinal endoscopy was performed in all the subjects to obtain five biopsy specimens from the lower 5 cm of the esophagus. Patients were considered to have GERD when they had a dilation of intercellular space (DIS)>0.74 μm at transmission electron microscopy.Patients with GERD were treated with pantoprazole,80 mg/day. Forced expiratory volume in one second (FEV1) was performed at entry and after 6 mo of treatment. Asthmatic symptoms were recorded. The required frequency of inhaling rapid acting 32-agonists was self-recorded in the patients' diaries.RESULTS: Seven symptomatic patients presented erosive esophagitis. Among the 18 asymptomatic patients, 11 presented DIS, while all symptomatic patients showed ultrastructural esophageal damage.Seven asymptomatic patients did not present DIS. At entry the mean of FEV1 was 1.91 L in symptomatic GERD patients and 1.88 L in asymptomatic GERD patients.After the treatment, 25 patients had a complete recovery of DIS and reflux symptoms. Twenty-three patients presented a regression of asthmatic symptoms with normalization of FEV1. Four patients reported a significant improvement of symptoms and their FEV1 was over 80%.CONCLUSION: GERD is a highly prevalent condition in asthma patients. Treatment with pantoprazole (80 mg/day)determines their improvement and complete regression. | Calabrese Carlo Fabbri Anna Areni Alessandra Scialpi Carlo Zahlane Desiree Di Febo Giulio | 2005 | World Journal of Gastroenterology2005，11，48： | 10 |
| 7 | Long-term alpha interferon and lamivudine combination therapy in non-responder patients with anti-HBe-positive chronic hepatitis B:Results of an open,controlled trial显示文摘AIM: To investigate the safety and efficacy of long-term combination therapy with alpha interferon and lamivudine in non-responsive patients with anti-HBe-positive chronic hepatitis B.METHODS: 34 patients received combination treatment (1 month lamivudine, 12 month lamivudine+interferon, 6month lamivudine), 24 received lamivudine (12 months),24 received interferon (12 months). Interferon was administered at 6 MU tiw and lamivudine at 100 mg orally once daily. Patients were followed up for 6 months after treatment.RESULTS: At the end of treatment, HBV DNA negativity rates were 88 % with lamivudine+interferon, 99 % with lamivudine and 55 % with interferon, (P=0.004, combination therapy vs. interferon, and P=0.001 lamivudine vs.interferon), and serum transaminase normalization rates were 84 %, 91% and 53 % (P=0.01 combination therapy vs. interferon, and P=0.012 lamivudine vs. interferon). Six months later, HBV DNA negativity rates were 44 % with lamivudine+interferon, 33 % with lamivudine and 25 % with interferon, and serum transaminase normalization rates were 61%, 42 % and 45 %, respectively, without statistical significance. No YMDD variants were observed with lamivudine+interferon (vs. 12 % with lamivudine). The combination therapy appeared to be safe. CONCLUSION: Although viral clearance and transaminase normalization are slower with long-term lamivudine+interferon than that with lamivudine alone, the combination regimen seems to provide more lasting benefits and to protect against the appearance of YMDD variants. Studies with other regimens regarding sequence and duration are needed. | M.

| 8 | Pancreatic ductal adenocarcinoma screening:New perspectives显示文摘Pancreatic ductal adenocarcinoma accounts for more than 90% of all pancreatic cancers and its incidence has increased significantly worldwide.Patients with pancreatic ductal adenocarcinoma have a poor outcome and more than 95% of the people affected die from the disease within 12 mo after diagnosis.Surgery is the first-line treatment in the case of resectable neoplasm,but only 20% of patients are candidates for this approach.One of the reasons there are few candidates for surgery is that,during the early phases of the disease,the symptoms are poor or non-specific.Early diagnosis is of crucial importance to improve patient outcome;therefore,we are looking for a good screening test.The screening test must identify the disease in an early stage in order to be effective;having said this,a need exists to introduce the concept of 'early' ductal adenocarcinoma.It has been reported that at least five additional years after the occurrence of the initiating mutation are required for the acquisition of metastatic ability of pancreatic adenocarcinoma and patients die an average of two years thereafter.We have reviewed the most recent literature in order to evaluate the present and future perspectives of screening programs of this deadly disease. | Raffaele Pezzilli Dario Fabbri Andrea Imbrogno | 2012 | World Journal of Gastroenterology2012，18，36： | 7 |
| 9 | Microbiota-gut-brain axis and its affect inflammatory bowel disease:Pathophysiological concepts and insights for clinicians显示文摘Despite the bi-directional interaction between gut microbiota and the brain not being fully understood,there is increasing evidence arising from animal and human studies that show how this intricate relationship may facilitate inflammatory bowel disease(IBD)pathogenesis,with consequent important implications on the possibility to improve the clinical outcomes of the diseases themselves,by acting on the different components of this system,mainly by modifying the microbiota.With the emergence of precision medicine,strategies in which patients with IBD might be categorized other than for standard gut symptom complexes could offer the opportunity to tailor therapies to individual patients.The aim of this narrative review is to elaborate on the concept of the gutbrain-microbiota axis and its clinical significance regarding IBD on the basis of recent scientific literature,and finally to focus on pharmacological therapies that could allow us to favorably modify the function of this complex system. | Emanuele Sinagra Erika Utzeri Gaetano Cristian Morreale Carlo Fabbri Fabio Pace Andrea Anderloni | 2020 | World Journal of Clinical Cases2020，8，6： | 7 |
| 10 | Using lysosomal membrane stability of haemocytes in Ruditapes philippinarum as a biomarker of cellular stress to assess contamination by caffeine, ibuprofen, carbamazepine and novobiocin显示文摘Although pharmaceuticals have beendetected in the environment only in the range from ng/L to μg/L, it has beendemonstrated that they can adversely affect the health status of aquatic organisms. Lysosomal membrane stability (LMS) has previously been applied as an indicator of cellularwell-being todetermine health status in bivalve mussels. The objective of this study is to evaluate LMS in Ruditapes philippinarum haemolymph using the neutral red retention assay (NRRA). Clamswere exposed in laboratory conditions to caffeine (0.1, 5, 15, 50 μg/L), ibuprofen (0.1, 5, 10, 50 μg/L), carbamazepine and novobiocin (both at 0.1, 1, 10, 50 μg/L) for35days. Results show adose-dependent effect of the pharmaceuticals. The neutral red retention time measured at the end of the bioassaywas significantly reduced by 50% after exposure to environmental concentrations (p < 0.05) (caffeine = 15 μg/L; ibuprofen = 10 μg/L; carbamazepine = 1 μg/L and novobiocin = 1 μg/L), compared to controls. Clams exposed to these pharmaceuticalswere considered to present adiminished health status (retention time <45 min), significantlyworse than controls (96 min) (p < 0.05). The predicted no environmental effect concentration (PNEC) results showed that these pharmaceuticals are very toxic at the environmental concentrations tested. Measurement of the alteration of LMS has been found to be a sensitive technique that enables evaluation of the health status of clams after exposure to pharmaceuticals under laboratory conditions, thus representing a robust Tier-1 screening biomarker. | Gabriela V.

| 11 | 日本南海海槽俯冲增生楔前缘的构造变形特征显示文摘对增生楔不同压力—温度条件下的构造变形、流体活动、沉积特征、岩石物性和化学组成等多方面的直接观测,可以帮助分析俯冲带地震的蕴育和发生的环境与机理。通过参加IODP的日本南海海槽发震带研究项目(NanTroSEIZE)第一阶段316航次所收集到的大量第一手数据和资料,分别在4个站位上(C0004,C0006,C0007,C0008)对日本南海海槽增生楔前缘岩芯尺度上的构造变形进行了详细分析,并且讨论了岩芯尺度上的构造变形与增生楔中大尺度的非序列分支逆冲断层和前缘逆冲断层的构造变形之间的关系。发现逆冲变形不是只在大尺度的逆冲断层面上进行,而是弥散分布在主逆冲断层面、次级逆冲断层面以及断层面之间的更小的尺度上。小尺度构造的倾向与大尺度断层的倾向有较好的一致性,表明它们是在相同的应力场下所形成的。在增生楔浅部高角度的正断层比较发育,显示张性应力场特征,同时所获得的岩芯尺度上的地层倾角较大并倾向与反射地震以及区域地质分析结果非常吻合,而在深部,特别是在大尺度逆冲断层发育带附近,各种类型的断层、滑移变形带、节理等非常普遍,同时层理与劈理的产状的复杂变化更多地受控于复杂的逆冲断层带的作用。 | 李春峰 苏新 姜涛 Ujiie K Fabbri O Yamaguchi A Chester F M Kimura G | 2010 | 地球科学进展2010，25，2： | 6 |
| 12 | Long-term metformin therapy and vitamin B12 deficiency: An association to bear in mind显示文摘To date,metformin remains the first-line oral glucose-lowering drug used for the treatment of type 2 diabetes thanks to its well-established long-term safety and efficacy profile.Indeed,metformin is the most widely used oral insulinsensitizing agent,being prescribed to more than 100 million people worldwide,including patients with prediabetes,insulin resistance,and polycystic ovary syndrome.However,over the last decades several observational studies and meta-analyses have reported a significant association between long-term metformin therapy and an increased prevalence of vitamin B12 deficiency.Of note,evidence suggests that long-term and high-dose metformin therapy impairs vitamin B12 status.Vitamin B12(also referred to as cobalamin)is a water-soluble vitamin that is mainly obtained from animal-sourced foods.At the cellular level,vitamin B12 acts as a cofactor for enzymes that play a critical role in DNA synthesis and neuroprotection.Thus,vitamin B12 deficiency can lead to a number of clinical consequences that include hematologic abnormalities(e.g.,megaloblastic anemia and formation of hypersegmented neutrophils),progressive axonal demyelination and peripheral neuropathy.Nevertheless,no definite guidelines are currently available for vitamin B12 deficiency screening in patients on metformin therapy,and vitamin B12 deficiency remains frequently unrecognized in such individuals.Therefore,in this“field of vision”article we propose a list of criteria for a cost-effective vitamin B12 deficiency screening in metformin-treated patients,which could serve as a practical guide for identifying individuals at high risk for this condition.Moreover,we discuss additional relevant topics related to this field,including:(1)The lack of consensus about the exact definition of vitamin B12 deficiency;(2)The definition of reliable biomarkers of vitamin B12 status;(3)Causes of vitamin B12 deficiency other than metformin therapy that should be identified promptly in metformin-treated patients for a proper differential diagnosis;and(4)Potential pathophysiological mechanisms underlying metformin-induced vitamin B12 deficiency.Finally,we briefly review basic concepts related to vitamin B12 supplementation for the treatment of vitamin B12 deficiency,particularly when this condition is induced by metformin. | Marco Infante Martina Leoni Massimiliano Caprio Andrea Fabbri | 2021 | World Journal of Diabetes2021，12，7： | 6 |

| 14 | New oral agents for erectile dysfunction: what is changing in our practice?显示文摘Erectile dysfunction (ED) is a highly prevalent disorder affecting an estimated 152 million men worldwide and is associated with a variety of behavioral risk factors, such as cigarette smoking and excessive alcohol consumption, as well as numerous age-related medical conditions, notably type-2 diabetes mellitus and cardiovascular disease. A rational step-wise approach which includes comprehensive medical and sexual history, a focused physical examination and essential laboratory tests such as fasting glucose, lipid profile and testosterone assay is to be preferred. Current diagnostic work-up does not recommend any of the specialized tests which were previously considered mandatory-i. e. penile pharmacotesting, Duplex ultrasound and nocturnal penile tumescence. Hormonal replacement therapy is appropriate only in the hypogonadal male with ED. Prior to direct intervention, the physician should consider altering modifiable risk factors or causes, although frequently insufficient to reverse ED completely. When indicated, oral therapy with new molecules (phosphodiesterase inhibitors or apomorphine) is the first-line treatment for the majority of patients because of potential benefits and lack of invasiveness. | Antonio Aversa Andrea Fabbri | 2001 | Asian Journal of Andrology2001，3，3： | 4 |

| 16 | Endoscopic ultrasound guided biliary drainage显示文摘Endoscopic retrograde cholangio-pancreatography is the most appropriate technique for treating common bile duct and pancreatic duct stenosis secondary to benign and malignant diseases. Even if the procedure is performed by skillful endoscopist, there are patients in whom endoscopic stent placement is not possible. Common causes of failure include complex peripapillary diverticula, prior surgery procedures, tumor involvement of the papilla, biliary sphincter stenosis, and impacted stones. Percutaneous trans-hepatic biliary drainage (PTBD) and surgical intervention carry morbidity and mortality. Recently endoscopic ultrasonography-guided biliary drainage has been reported as an alternative technique. Endoscopic ultrasonography- guided biliary drainage using either direct access or a rendezvous technique has attracted attention as an alternative procedure to PTBD, with a technical success between 75%-100% and with low complication rate. We have reviewed published data on EUS guided biliary drainage procedures with the aim of summarizing the efficacy and safety of this promising method. | Ilaria Tarantino Luca Barresi Carlo Fabbri Mario Traina | 2012 | World Journal of Gastrointestinal Endoscopy2012，4，7： | 3 |
| 17 | 内镜超声治疗及其系统回顾显示文摘当代减少外科手术治疗和介入辐射的理念有力地促进了目前内镜超声治疗手段的发展水平。内镜超声已经应用于胰腺积液引流,坏死灶切除,胆管造影及引流,胰管造影及引流,胆囊引流,腹腔及盆腔引流,腹腔丛阻滞及消融,囊肿切除,血管介入,抗肿瘤药物导入,校准放置放疗及抵近放射治疗等领域。然而该技术对操作要求较高,操作人员必须同时精通内镜及内镜介入操作,如内镜下逆行胰胆管造影术(ERCP)及胃肠道支架放置等技术。本文着眼于近20年内发表的所有相关文献进行系统回顾,在循证医学的基础上对现行发表文章进行相对客观的评价,力求推动该领域内的进一步发展。 | 龚雪屹 汪谦 Fabbri C Luigiano C Lisotti A | 2014 | 中华普通外科学文献(电子版)2014，8，6： | 3 |
| 18 | Effect of omeprazole on symptoms and ultrastructural esophageal damage in acid bile reflux显示文摘AIM: To value whether omeprazole could induce the healing of DIS and regression of symptoms in patients with DGER.METHODS: We enrolled 15 symptomatic patients with a pathological esophageal 24-h pH-metry and bilimetry.Patients underwent endoscopy and biopsies were taken from the distal esophagus. Specimens were analyzed at histology and transmission electron microscopy (TEM).Patients were treated with omeprazole 40 mg/d for 3 mo and then endoscopy with biopsies was repeated. Patients with persistent heartburn and/or with an incomplete recovery of DIS were treated for 3 more months and endoscopy with biopsies was performed.RESULTS: Nine patients had a non-erosive reflux disease at endoscopy (NERD) while 6 had erosive esophagitis (ERD). At histology, of the 6 patients with erosive esophagus,5 had mild esophagitis and 1 moderate esophagitis. No patients with NERD showed histological signs of esophagitis.After 3 mo of therapy, 13/15 patients (86.7%, P<0.01)showed a complete recovery of DIS and disappearance of heartburn. Of the 2 patients treated for 3 more months,complete recovery of DIS and heartburn were achieved in one.CONCLUSION: Three or 6 mo of omeprazole therapy led to a complete regression of the ultrastructural esophageal damage in 86.7% and in 93% of patients with DGER, NERD and ERD respectively. The ultrastructural recovery of the epithelium was accompanied by regression of heartburn in all cases. | Carlo Calabrese Anna Fabbri Mauro Bortolotti Giovanna Cenacchi Scialpi Carlo Desiree Zahlane Mario Miglioli Giulio Di Febo | 2005 | World Journal of Gastroenterology2005，11，12： | 3 |
| 19 | Current status of peroral cholangioscopy in biliary tract diseases显示文摘Peroral cholangioscopy(POC) is an important tool for the management of a selected group of biliary diseases. Because of its direct visualization, POC allows targeted diagnostic and therapeutic procedures. POC can be performed using a dedicated cholangioscope that is advanced through the accessory channel of a duodenoscope or via the insertion of a small-diameter endoscope directly into the bile duct. POC was first described in the 1970 s, but the use of earlier generation devices was substantially limited by the cumbersome equipment setup and high repair costs. For nearly ten years, several technical improvements, including the single-operator system, high-quality images, the development of dedicated accessories and the increased size of the working channel, have led to increased diagnostic accuracy, thus assisting in the differentiation of benign and malignant intraductal lesions, targeting biopsies and the precise delineation of intraductal tumor spread before surgery. Furthermore, lithotripsy of difficult bile duct stones, ablative therapies for biliary malignancies and direct biliary drainage can be performed under POC control. Recent developments of new types of conventional POCs allow feasible, safe and effective procedures at reasonable costs. In the current review, we provide an updated overview of POC, focusing our attention on the main current clinical applications and on areas for future research. | Stefania Ghersi Lorenzo Fuccio Marco Bassi Carlo Fabbri Vincenzo Cennamo | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，5： | 3 |
| 20 | Gastric autoimmune disorders in patients with chronic hepatitis C before,during and after interferon-alpha therapy显示文摘AIM: To explore the prevalence of autoimmune gastritis in chronic hepatitis C virus (HCV) patients and the influence of α-intefferon (IFN) treatment on autoimmune gastritis.METHODS: We performed a prospective study on 189patients with positive anti-HCV and viral RNA enrolled in a 12-month IFN protocol. We evaluated: a) the baseline prevalence of autoimmune gastritis, b) the impact of IFN treatment on development of biochemical signs of autoimmune gastritis (at 3, 6 and 12 months), c) the evolution after IFN withdrawal (12 months) in terms of anti-gastric-parietal-cell antibodies (APCA), gastrin, anti-thyroid, and anti-non-organ-specific antibodies.RESULTS: APCA positivity and 3-fold gastrin levels were detected in 3 (1.6 %) and 9 (5 %) patients, respectively, at baseline, in 25 (13 %) and 31 (16 %) patients at the end of treatment (both P<0.001, vs baseline), and in 7 (4 %) and 14 (7 %) patients 12 months after withdrawal (P=0.002and ,P=0.01 respectively, vs baseline; P=not significant vs end of treatment). The development of autoimmune gastritis was strictly associated with the presence of autoimmune thyroiditis (P =0.0001), no relationship was found with other markers of autoimmunity.CONCLUSION: In HCV patients, IFN frequently precipitates latent autoimmune gastritis, particularly in females. Following our 12-month protocol, the phenomenon generally regressed. Since APCA positivity and high gastrin levels are associated with the presence of antithyroid antibodies,development of autoimmune thyroiditis during IFN treatment may provide a surrogate preliminary indicator of possible autoimmune gastritis to limit the need for invasive examinations. | Carlo Fabbri M.Francesca Jaboli Silvia Giovanelli Francesco Azzaroli Alessandro Pezzoli Esterita Accogli Stefania Liva Giovanni Nigro Anna Miracolo Davide Festi Antonio Colecchia Marco Montagnani Enrico Roda Giuseppe Mazzella | 2003 | World Journal of Gastroenterology2003，9，7： | 3 |
