| 1 | Hepatic echinococcosis:Clinical and therapeutic aspects显示文摘Echinococcosis or hydatid disease(HD)is a zoonosis caused by the larval stages of taeniid cestodes belonging to the genus Echinococcus.Hepatic echinococcosis is a life-threatening disease,mainly differentiated into alveolar and cystic forms,associated with Echinoccus multilocularis(E.multilocularis)and Echinococcus granulosus(E.granulosus)infection,respectively.Cystic echinococcosis(CE)has a worldwide distribution,while hepatic alveolar echinococcosis(AE)is endemic in the Northern hemisphere,including North America and several Asian and European countries,like France,Germany and Austria.E.granulosus young cysts are spherical,unilocular vesicles,consisting of an internal germinal layer and an outer acellular layer.Cyst expan-sion is associated with a host immune reaction and the subsequent development of a fibrous layer,called the pericyst;old cysts typically present internal septations and daughter cysts.E.multilocularis has a tumorlike,infiltrative behavior,which is responsible for tissue destruction and finally for liver failure.The liver is the main site of HD involvement,for both alveolar and cystic hydatidosis.HD is usually asymptomatic for a long period of time,because cyst growth is commonly slow;the most frequent symptoms are fatigue and abdominal pain.Patients may also present jaundice,hepatomegaly or anaphylaxis,due to cyst leakage or rupture.HD diagnosis is usually accomplished with the combined use of ultrasonography and immunodiagnosis;furthermore,the improvement of surgical techniques,the introduction of minimally invasive treatments[such as puncture,aspiration,injection,re-aspiration(PAIR)]and more effective drugs(such as benzoimidazoles)have deeply changed life expectancy and quality of life of patients with HD.The aim of this article is to provide an up-todate review of biological,diagnostic,clinical and therapeutic aspects of hepatic echinococcosis. | Giuseppe Nunnari Marilia R Pinzone Salvatore Gruttadauria Benedetto M Celesia Giordano Madeddu Giulia Malaguarnera Piero Pavone Alessandro Cappellani Bruno Cacopardo | 2012 | World Journal of Gastroenterology2012，18，13： | 72 |
| 2 | Liver stiffness in the hepatitis B virus carrier:A non-invasive marker of liver disease influenced by the pattern of transaminases显示文摘AIM: To investigate the usefulness of transient elastography by Fibroscan (FS),a rapid non-invasive technique to evaluate liver fibrosis,in the management of chronic hepatitis B virus (HBV) carriers.METHODS: In 297 consecutive HBV carriers,we studied the correlation between liver stiffness (LS),stage of liver disease and other factors potentially influencing FS measurements.In 87 chronic hepatitis B (CHB) patients,we monitored the FS variations according to the spontaneous or treatment-induced variations of biochemical activity during follow-up.RESULTS: FS values were 12.3 ± 3.3 kPa in acute hepatitis,10.3 ± 8.8 kPa in chronic hepatitis,4.3 ± 1.0 kPa in inactive carriers and 4.6 ± 1.2 kPa in blood donors.We identified the cut-offs of 7.5 and 11.8 kPa for the diagnosis of fibrosis ≥ S3 and cirrhosis respectively,showing 93.9% and 86.5% sensitivity,88.5% and 96.3% specificity,76.7% and 86.7% positive predictive value (PPV),97.3% and 96.3% negative predictive value (NPV) and 90.1% and 94.2% diagnostic accuracy.At multivariate analysis in 171 untreated carriers,fibrosis stage (t = 13.187,P < 0.001),active vs inactive HBV infection (t = 6.437,P < 0.001),alanine aminotransferase (ALT) (t = 4.740,P < 0.001) and HBV-DNA levels (t = -2.046,P = 0.042) were independently associated with FS.Necroinflammation score (t = 2.158,> 10/18 vs ≤ 10/18,P = 0.035) and ALT levels (t = 3.566,P = 0.001) were independently associated with LS in 83 untreated patients without cirrhosis and long-term biochemical remission (t = 4.662,P < 0.001) in 80 treated patients.During FS monitoring (mean follow-up 19.9 ± 7.1 mo) FS values paralleled those of ALT in patients with hepatitis exacerbation (with 1.2 to 4.4-fold increases in CHB patients) and showed a progressive decrease during antiviral therapy.CONCLUSION: FS is a non-invasive tool to monitor liver disease in chronic HBV carriers,provided that the pattern of biochemical activity is taken into account.In the inactive carrier,it identifies non-HBV-related causes of liver damage and transient reactivations.In CHB patients,it may warrant a more appropriate timing of control liver biopsies. | Filippo Oliveri Barbara Coco Pietro Ciccorossi Piero Colombatto Veronica Romagnoli Beatrice Cherubini Ferruccio Bonino Maurizia Rossana Brunetto | 2008 | World Journal of Gastroenterology2008，14，40： | 43 |
| 3 | Biochemical mechanisms in drug-induced liver injury:Certainties and doubts显示文摘Drug-induced liver injury is a significant and still unresolved clinical problem.Limitations to knowledge about the mechanisms of toxicity render incomplete the detection of hepatotoxic potential during preclinical development.Several xenobiotics are lipophilic substances and their transformation into hydrophilic compounds by the cytochrome P-450 system results in production of toxic metabolites.Aging,preexisting liver disease,enzyme induction or inhibition,genetic variances,local O2 supply and,above all,the intrinsic molecular properties of the drug may affect this process.Necrotic death follows antioxidant consumption and oxidation of intracellular proteins,which determine increased permeability of mitochondrial membranes,loss of potential,decreased ATP synthesis,inhibition of Ca2+-dependent ATPase,reduced capability to sequester Ca2+ within mitochondria,and membrane bleb formation.Conversely,activation of nucleases and energetic participation of mitochondria are the main intracellular mechanisms that lead to apoptosis.Non-parenchymal hepatic cells are inducers of hepatocellular injury and targets for damage.Activation of the immune system promotes idiosyncratic reactions that result in hepatic necrosis or cholestasis,in which different HLA genotypes might play a major role.This review focuses on current knowledge of the mechanisms of drug-induced liver injury and recent advances on newly discovered mechanisms of liver damage.Future perspectives including new frontiers for research are discussed. | Ignazio Grattagliano Leonilde Bonfrate Catia V Diogo Helen H Wang David QH Wang Piero Portincasa | 2009 | World Journal of Gastroenterology2009，15，39： | 30 |

| 5 | Pan-enteric dysmotility,impaired quality of life and alexithymia in a large group of patients meeting ROMEⅡ criteria for irritable bowel syndrome显示文摘AIM:Psychological factors, altered motility and sensation disorders of the intestine can be variably associated with irritable bowel syndrome (IBS). Such aspects have not been investigated simultaneously. The aim of this paper was to evaluate gastrointestinal motility and symptoms, psychological spectrum and quality of life in a large group of IBS patients in southern Italy.METHODS: One hundred IBS patients (F:M=73:27, age 48±2 years, mean±SE) fulfilling ROME Ⅱ criteria matched with 100 healthy subjects (F:M=70:30, 45±2 years). Dyspepsia,bowel habit, alexithymia, psycho-affective profile and quality of life were assessed using specific questionnaires. Basally and postprandially, changes in gallbladder volumes and antral areas after liquid meal and orocaecal transit time (OCTT)were measured respectively by ultrasonography and H2-breath test. Appetite, satiety, fullness, nausea, and epigastric pain/discomfort were monitored using visual-analogue scales.RESULTS: Compared with controls, IBS patients had increased dyspepsia (score 12.6±0.7 VS 5.1±0.2, P<0.0001),weekly bowel movements (12.3±0.4 VS 5.5±0.2, P<0.00001, comparable stool shape), alexithymia (score 59.11.1 VS40.5±1.0, P=0.001), poor quality of life and psychoaffective profile. IBS patients had normal gallbladderemptying, but delayed gastric emptying (T50:35.5±1.0 VS 26.1±0.6 min, P=0.00001) and OCTT (163.0±5.4 VS96.6±1.8min, P=0.00001). Fullness, nausea, and epigastric pain/discomfort were greater in IBS than in controls.CONCLUSION: ROME Ⅱ IBS patients have a pan-enteric dysmotility with frequent dyspepsia, associated with psychological morbidity and greatly impaired quality of life.The presence of alexithymia, a stable trait, is a novel finding of potential interest to detect subgroups of IBS patients with different patterns recoveed after therapy. | Piero Portincasa Antonio Moschetta Giuseppe Baldassarre Donato F.

| 6 | Therapy of gallstone disease:What it was,what it is,what it will be显示文摘Cholesterol gallstone disease is a common clinical condition influenced by genetic factors,increasing age,female gender,and metabolic factors.Although laparoscopic cholecystectomy is currently considered the gold standard in treating patients with symptomatic gallstones,new perspectives regarding medical therapy of cholelithiasis are currently under discussion,also taking into account the pathogenesis of gallstones,the natural history of the disease and the analysis of the overall costs of therapy.A careful selection of patients may lead to successful nonsurgical therapy in symptomatic subjects with a functioning gallbladder harboring small radiolucent stones.The classical oral litholysis by ursodeoxycholic acid has been recently paralleled by new experimental observations,suggesting that cholesterol-lowering agents which inhibit cholesterol synthesis (statins) or intestinal cholesterol absorption (ezetimibe),or drugs acting on specific nuclear receptors involved in cholesterol and bile acid homeostasis,might be proposed as additional approaches for treating cholesterol gallstones.In this review we discuss old,recent and future perspectives on medical treatment of cholesterol cholelithiasis. | Piero Portincasa Agostino Di Ciaula Leonilde Bonfrate David QH Wang | 2012 | World Journal of Gastrointestinal Pharmacology and Therapeutics2012，3，2： | 21 |
| 7 | Small intestine bacterial overgrowth and irritable bowel syndrome-related symptoms:Experience with Rifaximin显示文摘AIM:To estimate the prevalence of small intestinal bacterial overgrowth(SIBO) in our geographical area(Western Sicily,Italy) by means of an observational study,and to gather information on the use of locally active,non-absorbable antibiotics for treatment of SIBO.METHODS:Our survey included 115 patients fulfilling the Rome □ criteria for diagnosis of irritable bowel syndrome(IBS);a total of 97 patients accepted to perform a breath test with lactulose(BTLact),and those who had a positive test,received Rifaximin(Normix,Alfa Wassermann) 1200 mg/d for 7 d;3 wk after the end of treatment,the BTLact was repeated.RESULTS:Based on the BTLact results,SIBO was present in about 56% of IBS patients,and it was responsible for some IBS-related symptoms,such as abdominal bloating and discomfort,and diarrhoea.1-wk treatment with Rifaximin turned the BTLact to negative in about 50% of patients and significantly reduced the symptoms,especially in those patients with an alternated constipation/diarrhoea-variant IBS.CONCLUSION:SIBO should be always suspected in patients with IBS,and a differential diagnosis is done by means of a 'breath test'.Rifaximin may represent a valid approach to the treatment of SIBO. | Sergio Peralta Claudia Cottone Tiziana Doveri Piero Luigi Almasio Antonio Craxi | 2009 | World Journal of Gastroenterology2009，15，21： | 19 |

| 9 | Silybin counteracts lipid excess and oxidative stress in cultured steatotic hepatic cells显示文摘AIM: To investigate in vitro the therapeutic effect and mechanisms of silybin in a cellular model of hepatic steatosis.METHODS: Rat hepatoma Fa O cells were loaded with lipids by exposure to 0.75 mmol/L oleate/palmitate for 3 h to mimic liver steatosis. Then, the steatotic cells were incubated for 24 h with different concentrations(25 to 100 μmol/L) of silybin as phytosome complex with vitamin E. The effects of silybin on lipid accumulation and metabolism, and on indices of oxidative stress were evaluated by absorption and fluorescence microscopy, quantitative real-time PCR, Western blot, spectrophotometric and fluorimetric assays.RESULTS: Lipid-loading resulted in intracellular triglyceride(TG) accumulation inside lipid droplets, whose number and size increased. TG accumulation was mediated by increased levels of peroxisome proliferator-activated receptors(PPARs) and sterol regulatory element-binding protein-1c(SREBP-1c). The lipid imbalance was associated with higher production of reactive oxygen species(ROS) resulting in increased lipid peroxidation, stimulation of catalase activity and activation of nuclear factor kappa-B(NF-κB). Incubation of steatotic cells with silybin 50 μmol/L significantly reduced TG accumulation likely by promoting lipid catabolism and by inhibiting lipogenic pathways, as suggested by the changes in carnitine palmitoyltransferase 1(CPT-1), PPAR and SREBP-1c levels. The reduction in fat accumulation exerted by silybin in the steatotic cells was associated with the improvement of the oxidative imbalance caused by lipid excess as demonstrated by the reduction in ROS content, lipid peroxidation, catalase activity and NF-κB activation.CONCLUSION: We demonstrated the direct antisteatotic and anti-oxidant effects of silybin in steatotic cells, thus elucidating at a cellular level the encouraging results demonstrated in clinical and animal studies. | Giulia Vecchione Elena Grasselli Adriana Voci Francesca Baldini Ignazio Grattagliano David QH Wang Piero Portincasa Laura Vergani | 2016 | World Journal of Gastroenterology2016，22，26： | 13 |

| 11 | The enhanced X-ray Timing and Polarimetry mission—eXTP显示文摘In this paper we present the enhanced X-ray Timing and Polarimetry mission—eXTP. eXTP is a space science mission designed to study fundamental physics under extreme conditions of density, gravity and magnetism. The mission aims at determining the equation of state of matter at supra-nuclear density, measuring effects of QED, and understanding the dynamics of matter in strong-field gravity. In addition to investigating fundamental physics, eXTP will be a very powerful observatory for astrophysics that will provide observations of unprecedented quality on a variety of galactic and extragalactic objects. In particular, its wide field monitoring capabilities will be highly instrumental to detect the electro-magnetic counterparts of gravitational wave sources.The paper provides a detailed description of:(1) the technological and technical aspects, and the expected performance of the instruments of the scientific payload;(2) the elements and functions of the mission, from the spacecraft to the ground segment. | ShuangNan Zhang Andrea Santangelo Marco Feroci YuPeng Xu FangJun Lu Yong Chen Hua Feng Shu Zhang Sφren Brandt Margarita Hernanz Luca Baldini Enrico Bozzo Riccardo Campana Alessandra De Rosa YongWei Dong Yuri Evangelista Vladimir Karas Norbert Meidinger Aline Meuris Kirpal Nandra Teng Pan Giovanni Pareschi Piotr Orleanski QiuShi Huang Stephane Schanne Giorgia Sironi Daniele Spiga Jiri Svoboda Gianpiero Tagliaferri Christoph Tenzer Andrea Vacchi Silvia Zane Dave Walton ZhanShan Wang Berend Winter Xin Wu Jean J.M.in't Zand Mahdi Ahangarianabhari Giovanni Ambrosi Filippo Ambrosino Marco Barbera Stefano Basso Jörg Bayer Ronaldo Bellazzini Pierluigi Bellutti Bruna Bertucci Giuseppe Bertuccio Giacomo Borghi XueLei Cao Franck Cadoux Francesco Ceraudo TianXiang Chen Yu Peng Chen Jerome Chevenez Marta Civitani Wei Cui WeiWei Cui Thomas Dauser Ettore Del Monte Sergio Di Cosimo Sebastian Diebold Victor Doroshenko Michal Dovciak YuanYuan Du Lorenzo Ducci QingMei Fan Yannick Favre Fabio Fuschino JoséLuis Ga'lvez Min Gao MingYu Ge Olivier Gevin Marco Grassi QuanYing Gu YuDong Gu DaWei Han Bin Hong Wei Hu Long Ji ShuMei Jia WeiChun Jiang Thomas Kennedy Ingo Kreykenbohm Irfan Kuvvetli Claudio Labanti Luca Latronico Gang Li MaoShun Li Xian Li Wei Li ZhengWei Li Olivier Limousin HongWei Liu XiaoJing Liu Bo Lu Tao Luo Daniele Macera Piero Malcovati Adrian Martindale Malgorzata Michalska Bin Meng Massimo Minuti Alfredo Morbidini Fabio Muleri Stephane Paltani Emanuele Perinati Antonino Picciotto Claudio Piemonte JinLu Qu Alexandre Rachevski Irina Rashevskaya Jerome Rodriguez Thomas Schanz ZhengXiang Shen LiZhi Sheng JiangBo Song LiMing Song Carmelo Sgro Liang Sun Ying Tan Phil Uttley Bo Wang DianLong Wang GuoFeng Wang Juan Wang LangPing Wang YuSa Wang Anna L.Watts XiangYang Wen Jörn Wilms ShaoLin Xiong JiaWei Yang Sheng Yang YanJi Yang Nian Yu WenDa Zhang Gianluigi Zampa Nicola Zampa Andrzej A.Zdziarski AiMei Zhang ChengMo Zhang Fan Zhang Long Zhang Tong Zhang Yi Zhang XiaoLi Zhang ZiLiang Zhang BaoSheng Zhao ShiJie Zheng Yu Peng Zhou Nicola Zorzi J.Frans Zwart | 2019 | Science China(Physics,Mechanics & Astronomy)2019，62，2： | 11 |
| 12 | Prevention of vertical transmission of hepatitis B virus infection显示文摘Hepatitis B virus(HBV)is the leading cause of chronic viral hepatitis.Annually,almost two million children younger than 5 years acquire the infection,mostly through vertical or horizontal transmission in early life.Vertical transmission of HBV is a high efficacy phenomenon ranging,in the absence of any preventive interventions,from 70%to 90%for hepatitis e antigen positive mothers and from 10%to 40%for hepatitis e antigen-negative mothers.Maternal viraemia is a preeminent risk factor for vertical transmission of HBV.Maternal screening is the first step to prevent vertical transmission of HBV.Hepatitis B passive and active immunoprophylaxis at birth together with antiviral treatment of highly viraemic mothers are the key strategies for global elimination of HBV infection.Strategies are needed to promote implementation of birth-dose vaccination and hepatitis B immunoglobulins in low-and middle-income countries where the prevalence of the infection is at the highest. | Piero Veronese Icilio Dodi Susanna Esposito Giuseppe Indolfi | 2021 | World Journal of Gastroenterology2021，27，26： | 10 |
| 13 | Extraintestinal manifestations in a large series of Italian inflammatory bowel disease patients显示文摘AIM:To investigate prevalence,type and time of onset of extraintestinal manifestations(EIMs)in a series of Italian inflammatory bowel disease(IBD)patients.METHODS:Data of 811 IBD consecutive patients,first referred to our Centre from 2000 to 2011,were retrospectively evaluated.RESULTS:Eight hundred and eleven IBD patients(437M,374 F)were studied:595 ulcerative colitis(UC)(73.4%)and 216 Crohn’s disease(CD)(26.6%).Among these,329(40.6%)showed EIMs:210 UC(35.3%)and119 CD(55.1%)(P<0.0001).Considering the time of the diagnosis of IBD,37 EIMs(11.2%)were developed before,229(69.6%)after and 63(19.2%)were simultaneous.The type of EIM were as follows:240 musculoskeletal(29.6%),in 72 CD patients and in 168 UC(P<0.0001);47 mucocutaneous(5.8%),in 26 CD and in21 UC(P=0.0049);26 ocular(3.2%),in 16 CD and in10 UC(CD 7.4%vs UC 1.7%,P=0.0093);6 hepatobiliary(0.8%);10 endocrinological(1.2%).In particular,with regards to the involvement of the musculoskeletal system,arthritis Type 1 was found in 41 CD(19%)and in 61 UC(10.2%)(P=0.0012)and Type 2 in 25 CD(11.6%)and in 100 UC(16.8%)(P=0.0012).CONCLUSION:Mucocutaneous manifestations,arthritis Type 1 and uveitis were significantly more frequent in CD than UC.The complications of the musculoskeletal system were the mostly observed ones,often with symptoms more severe than intestinal ones,confirming the need for close cooperation with rheumatologists. | Maddalena Zippi Claudia Corrado Roberta Pica Eleonora Veronica Avallone Claudio Cassieri Daniela De Nitto Paolo Paoluzi Piero Vernia | 2014 | World Journal of Gastroenterology2014，20，46： | 10 |
| 14 | High-speed image reconstruction for optically sectioned,super-resolution structured illumination microscopy显示文摘Super-resolution structured illumination microscopy(SR-SIM)is an outstanding method for visualizing the subcellular dynamics in living cells.To date,by using elaborately designed systems and algorithms,SR-SIM can achieve rapid,optically sectioned,SR observation with hundreds to thousands of time points.However,real-time observation is still out of reach for most SIM setups as conventional algorithms for image reconstruction involve a heavy computing burden.To address this limitation,an accelerated reconstruction algorithm was developed by implementing a simplified workflow for SR-SIM,termed joint space and frequency reconstruction.This algorithm results in an 80-fold improvement in reconstruction speed relative to the widely used Wiener-SIM.Critically,the increased processing speed does not come at the expense of spatial resolution or sectioning capability,as demonstrated by live imaging of microtubule dynamics and mitochondrial tubulation. | Zhaojun Wang Tianyu Zhao Huiwen Hao Yanan Cai Kun Feng Xue Yun Yansheng Liang Shaowei Wang Yujie Sun Piero RBianco Kwangsung Oh Ming Lei | 2022 | Advanced Photonics2022，4，2： | 9 |
| 15 | Postoperative biliary adverse events following orthotopic liver transplantation: Assessment with magnetic resonance cholangiography显示文摘Biliary adverse events following orthotopic liver transplantation(OLT) are relatively common and continue to be serious causes of morbidity, mortality, and transplant dysfunction or failure. The development of these adverse events is heavily influenced by the type of anastomosis during surgery. The low specificity of clinical and biologic findings makes the diagnosis challenging. Moreover, direct cholangiographic procedures such as endoscopic retrograde cholangiopancreatography and percutaneous transhepatic cholangiography present an inadmissible rate of adverse events to be utilized in clinically low suspected patients. Magnetic resonance(MR) maging with MR cholangiopancreatography is crucial in assessing abnormalities in the biliary system after liver surgery, including liver transplant. MR cholangiopancreatography is a safe, rapid, noninvasive, and effective diagnostic procedure for the evaluation of biliary adverse events after liver transplantation, since it plays an increasingly important role in the diagnosis and management of these events. Onthe basis of a recent systematic review of the literature the summary estimates of sensitivity and specificity of MR cholangiopancreatography for diagnosis of biliary adverse events following OLT were 0.95 and 0.92, respectively. It can provide a non-invasive method of imaging surgical reconstruction of the biliary anastomoses as well as adverse events including anastomotic and non-anastomotic strictures, biliary lithiasis and sphincter of Oddi dysfunction in liver transplant recipients. Nevertheless, conventional T2-weighted MR cholangiography can be implemented with T1-weighted contrast-enhanced MR cholangiography using hepatobiliary contrast agents(in particular using Gd-EOBDTPA) in order to improve the diagnostic accuracy in the adverse events' detection such as bile leakage and strictures, especially in selected patients with biliaryenteric anastomosis. | Piero Boraschi Francescamaria Donati | 2014 | World Journal of Gastroenterology2014，20，32： | 9 |
| 16 | Chronic functional constipation is strongly linked to vitamin D deficiency显示文摘BACKGROUND Few studies have examined intestinal motility disorders, which are disabling conditions associated with chronic functional constipation, whose pathogenesis is actually not well-defined.AIM To investigate the relationship between serum 25-hydroxyvitamin D levels and functional chronic constipation associated to intestinal motility disorders.METHODS We performed a prospective case-control study, from May-June to November2017. Glucose/lactulose breath tests, radiopaque markers(multiple capsule techniques) and wireless motility capsule analysis were used to assess colonicand oro-cecal transit time, after excluding small-intestinal bacterial overgrowth condition. Then, we measured 25-hydroxyvitamin D levels in patients with intestinal motility disorders and we further evaluated the influence of intestinal motility disorders on psychological symptoms/quality of life using validated questionnaires, the Irritable Bowel Syndrome Quality of life(IBS-QOL), the Short Form Health Survey 12, and the Hospital Anxiety and Depression Scale 14(HADS-14 A and HADS-14 D).RESULTS We enrolled 86 patients with chronic functional constipation associated to intestinal motility disorders and 86 matched healthy subjects. Patients with intestinal motility disorders had lower 25-hydroxyvitamin D levels(P < 0.001), and they showed a significant impairment of all health-related quality of life and psychological tests(IBS-QOL, Short Form Health Survey 12-Physical Component Summary, Short Form Health Survey 12-Mental Component Summary, HADS-14 A and HADS-14 D), as compared to the control group(P < 0.001), which significantly correlated with low vitamin D levels(r =-0.57, P < 0.001; r = 0.21, P = 0.01; r =-0.48, P < 0.001; r =-0.57, P < 0.001; r =-0.29, P < 0.001, respectively). At multivariate analysis vitamin D low levels remained a significant independent risk factor for the occurrence of intestinal motility disorder(odds ratio = 1.19; 95% confidence interval: 1.14-1.26, P < 0.001).CONCLUSION Vitamin D deficiency, anxiety and depression symptoms are commonly associated with chronic functional constipation induced by intestinal motility disorders. Vitamin D serum levels should be routinely measured in these patients. | Alba Panarese Francesco Pesce Piero Porcelli Giuseppe Riezzo Palma Aurelia Iacovazzi Carla Maria Leone Massimo De Carne Caterina Mammone Rinaldi Endrit Shahini | 2019 | World Journal of Gastroenterology2019，25，14： | 8 |
| 17 | Does antecolic reconstruction decrease delayed gastric emptying after pancreatoduodenectomy?显示文摘Delayed gastric emptying(DGE) is a frequent complication after pylorus-preserving pancreatoduodenectomy(PpPD).Kawai and colleagues proposed pylorus-resecting pancreatoduodenectomy(PrPD) with antecolic gastrojejunal anastomosis to obviate DGE occurring after PpPD.Here we debate the reported differences in the prevalence of DGE in antecolic and retrocolic gastro/duodeno-jejunostomies after PrPD and PpPD,respectively.We concluded that the route of the gastro/duodeno-jejunal anastomosis with respect to the transverse colon;i.e.,antecolic route or retrocolic route,is not responsible for the differences in prevalence of DGE after pancreatoduodenectomy(PD) and that the impact of the reconstructive method on DGE is related mostly to the angulation or torsion of the gastro/duodeno-jejunostomy.We report a prevalence of 8.9% grade A DGE and 1.1% grade C DGE in a series of 89 subtotal stomach-preserving PDs with Roux-en Y retrocolic reconstruction with anastomosis of the isolated Roux limb to the stomach and single Roux limb to both the pancreatic stump and hepatic duct.Retrocolic anastomosis of the isolated first jejunal loop to the gastric remnant allows outflow of the gastric contents by gravity through a 'straight route'. | Nadia Peparini Piero Chirletti | 2012 | World Journal of Gastroenterology2012，18，45： | 8 |
| 18 | Primary sclerosing cholangitis: Updates in diagnosis and therapy显示文摘Primary sclerosing cholangitis (PSC) is a chronic cholestatic syndrome of unknown origin mostly found in males, and characterized by diffuse inflammation and fibrosis of both intra- and extra-hepatic bile ducts. So far, PSC is considered as an autoimmune hepatobiliary disease. In most cases the progression of PSC towards liver cirrhosis and liver failure is slow but irreversible, and liver transplantation is currently the only definitive treatment. In recent years,PSC has been an area of active research worldwide with great interest in etiology, pathogenesis, diagnosis, and therapeutic options such as hydrophilic ursodeoxycholic acid and immunosuppressive agent tacrolimus. Recent updates on clinical and therapeutic aspects of PSC are discussed in the present review. | Piero Portincasa Michele Vacca Antonio Moschetta Michele Petruzzelli Giuseppe Palasciano Karel J.van Erpecum Gerard P.van Berge-Henegouwen | 2005 | World Journal of Gastroenterology2005，11，1： | 7 |
| 19 | A silybin-phospholipids complex counteracts rat fatty liver degeneration and mitochondrial oxidative changes显示文摘AIM:To investigate the effectiveness of antioxidant compounds in modulating mitochondrial oxidative alterations and lipids accumulation in fatty hepatocytes.METHODS:Silybin-phospholipid complex containing vitamin E(Realsil) was daily administered by gavage(one pouch diluted in 3 mL of water and containing 15 mg vitamin E and 47 mg silybin complexed with phospholipids) to rats fed a choline-deprived(CD) or a high fat diet [20% fat,containing 71% total calories as fat,11% as carbohydrate,and 18% as protein,high fat diet(HFD)] for 30 d and 60 d,respectively.The control group was fed a normal semi-purified diet containing adequate levels of choline(35% total calories as fat,47% as carbohydrate,and 18% as protein).Circulating and hepatic redox active and nitrogen regulating molecules(thioredoxin,glutathione,glutathione peroxidase),NO metabolites(nitrosothiols,nitrotyrosine),lipid peroxides [malondialdehyde-thiobarbituric(MDA-TBA)],and pro-inflammatory keratins(K-18) were measured on days 0,7,14,30,and 60.Mitochondrial respiratory chain proteins and the extent of hepatic fatty infiltration were evaluated.RESULTS:Both diet regimens produced liver steatosis(50% and 25% of liver slices with CD and HFD,respectively) with no signs of necro-inflammation:fat infiltration ranged from large droplets at day 14 to disseminated and confluent vacuoles resulting in microvesicular steatosis at day 30(CD) and day 60(HFD).In plasma,thioredoxin and nitrosothiols were not significantly changed,while MDA-TBA,nitrotyrosine(from 6 ± 1 nmol/L to 14 ± 3 nmol/L day 30 CD,P < 0.001,and 12 ± 2 nmol/L day 60 HFD,P < 0.001),and K-18(from 198 ± 20 to 289 ± 21 U/L day 30 CD,P < 0.001,and 242 ± 23 U/L day 60 HFD,P < 0.001) levels increased significantly with ongoing steatosis.In the liver,glutathione was decreased(from 34.0 ± 1.3 to 25.3 ± 1.2 nmol/mg prot day 30 CD,P < 0.001,and 22.4 ± 2.4 nmol/mg prot day 60 HFD,P < 0.001),while thioredoxin and glutathione peroxidase were initially increased and then decreased.Nitrosothiols were constantly increased.MDA-TBA levels were five-fold increased from 9.1 ± 1.2 nmol/g to 75.6 ± 5.4 nmol/g on day 30,P < 0.001(CD) and doubled with HFD on day 60.Realsil administration significantly lowered the extent of fat infiltration,maintained liver glutathione levels during the first half period,and halved its decrease during the second half.Also,Realsil modulated thioredoxin changes and the production of NO derivatives and significantly lowered MDA-TBA levels both in liver(from 73.6 ± 5.4 to 57.2 ± 6.3 nmol/g day 30 CD,P < 0.01 and from 27.3 ± 2.1 nmol/g to 20.5 ± 2.2 nmol/g day 60 HFD,P < 0.01) and in plasma.Changes in mitochondrial respiratory complexes were also attenuated by Realsil in HFD rats with a major protective effect on Complex Ⅱ subunit CII-30.CONCLUSION:Realsil administration effectively contrasts hepatocyte fat deposition,NO derivatives formation,and mitochondrial alterations,allowing the liver to maintain a better glutathione and thioredoxin antioxidant activity. | Ignazio Grattagliano Catia V Diogo Maria Mastrodonato Ornella de Bari Michele Persichella David QH Wang Adriana Liquori Domenico Ferri Maria Rosaria Carratù Paulo J Oliveira Piero Portincasa | 2013 | World Journal of Gastroenterology2013，19，20： | 6 |
| 20 | 欧美饲料禁抗实践与启示显示文摘广东是畜牧生产和消费大省,多年来生猪、家禽、水产饲养量均位居全国前列,工业饲料产量连续13年位居全国之首,饲料产品质量也一直稳定在较高水平。但是,养殖业规模化、集约化快速发展中的一些负面问题不可忽视。抗生素在饲料中的不合法、不规范的使用,导致畜禽产品药物残留和产生细菌耐药性,不但影响动物的健康,而且影响到人类的食品安全和环境保护,这对我们畜牧饲料行业提出了严峻挑战。 | Piero Agostini Aidan Connolly 徐倩 周风珍 罗宙纶 | 2016 | 广东饲料2016，0，6： | 6 |
