| 2 | Management of ruptured hepatocellular carcinoma:Implications for therapy显示文摘AIM:To assess the treatment and tumor-related variables associated with outcome after treatment of spontaneously ruptured hepatocellular carcinoma (HCC).METHODS: Patients with ruptured HCC were identif ied. The complications, mortality and survival were assessed. The relationship between tumor size and the severity of hemoperitoneum and between tumor size and grade were examined.RESULTS: From January 1993 to January 2008, 556 patients with HCC with or without cirrhosis were evaluated; of which, 16 (2.87%) presented with spontaneous rupture. All but 1 patient had cirrhosis. Twelve patients underwent surgical resection while 4 underwent trans-cutaneous arterial catheter embolization (TAE) (trans-cutaneous arterial embolization). Early mortality (<30 d) was 25% (4 of 16) and was inversely relatedto Child-Pugh score; 3 of the 4 early deaths occurred in patients treated with TAE with 1 of 12 occurring in the resected group. There was no correlation between tumor size and grade or between size and severity of hemoperitoneum.CONCLUSION: Tumor size did not correlate with severity of the hemoperitoneum. There was an inverse relationship between G1-G3 (grade of cellular differentiation) HCC and dimensions. | Nicolò Bassi Ezio Caratozzolo Luca Bonariol Cesare Ruffolo Alessio Bridda Luigi Padoan Michele Antoniutti Marco Massani | 2010 | World Journal of Gastroenterology2010，16，10： | 26 |
| 3 | Blue carbon on the rise:challenges and opportunities显示文摘BLUE CARBON ON THE RISE Climate change is a global concem that requires urgent solutions.As a signatory to the Paris Agreement,China has committed to have its greenhouse gas emission reach a peak by the year 2030,which means that severe countermeasures for reducing emissions have to be put into practice.This is a hard mission given that development is still the top priority in the years to come for China.Under such circumstances,enhancing carbon sequestration becomes an effective approach to achieving the goal.While terrestrial green carbon sink is already in practice,the ocean carbon reservoir,containing 93%of global CO2,as 50 and 20 times the carbon inventories of atmosphere and land,respectively,has great potential to expand.Each year,at least 25% of the anthropogenic CO2 has been captured by marine ecosystems as blue carbon [1]. | Nianzhi Jiao Hong Wang Guanhua Xu Salvatore Aricò | 2018 | National Science Review2018，5，4： | 25 |
| 4 | Management of duodenal stump fistula after gastrectomy for gastric cancer: Systematic review显示文摘AIM: To identify the most effective treatment of duodenalstump fistula(DSF) after gastrectomy for gastric cancer.METHODS: A systematic review of the literature was performed. Pub Med, EMBASE, Cochrane Library, CILEA Archive, BMJ Clinical Evidence and Up To Date databases were analyzed. Three hundred eighty-eight manuscripts were retrieved and analyzed and thirteen studies published between 1988 and 2014 were finally selected according to the inclusion criteria, for a total of 145 cases of DSF, which represented our group of study. Only patients with DSF after gastrectomy for malignancy were selected. Data about patients' characteristics, type of treatment, short and long-term outcomes were extracted and analyzed. RESULTS: In the 13 studies different types of treatment were proposed: conservative approach, surgical approach, percutaneous approach and endoscopic approach(3 cases). The overall mortality rate was 11.7% for the entire cohort. The more frequent complications were sepsis, abscesses, peritonitis, bleeding, pneumonia and multi-organ failure. Conservative approach was performed in 6 studies for a total of 79 patients, in patients with stable general condition, often associated with percutaneous approach. A complete resolution of the leakage was achieved in 92.3% of these patients, with a healing time ranging from 17 to 71 d. Surgical approach included duodenostomy, duodenojejunostomy, pancreatoduodenectomy and the use of rectus muscle flap. In-hospital stay of patients who underwent relaparotomy ranged from 1 to 1035 d. The percutaneous approach included drainage of abscesses or duodenostomy(32 cases) and percutaneous biliary diversion(13 cases). The median healing time in this group was 43 d. CONCLUSION: Conservative approach is the treatment of choice, eventually associated with percutaneus drainage. Surgical approach should be reserved for severe cases or when conservative approaches fail. | Paolo Aurello Dario Sirimarco Paolo Magistri NiccolòPetrucciani Giammauro Berardi Silvia Amato Marcello Gasparrini Francesco D’Angelo Giuseppe Nigri Giovanni Ramacciato | 2015 | World Journal of Gastroenterology2015，21，24： | 19 |
| 5 | Acute appendicitis: Epidemiology, treatment and outcomesanalysis of 16544 consecutive cases显示文摘AIM To investigate the epidemiology,treatment and outcomes of acute appendicitis(AA) in a large population study.METHODS This is a retrospective cohort study derived from the administrative dataset of the Bergamo district healthcare system(more than 1 million inhabitants) from 1997 to 2013.Data about treatment,surgery,length of stay were collected.Moreover for each patients were registered data about relapse of appendicitis and hospital admission due to intestinal obstruction.RESULTS From 1997 to 2013 in the Bergamo district we collected 16544 cases of AA,with a crude incidence rate of 89/100000 inhabitants per year; mean age was 24.51 ± 16.17,54.7% were male and the mean Charlson's comorbidity index was 0.32 ± 0.92.Mortality was < 0.0001%.Appendectomy was performed in 94.7% of the patients and the mean length of stay was 5.08 ± 2.88 d; the cumulative hospital stay was 5.19 ± 3.36 d and 1.2% of patients had at least one further hospitalization due intestinal occlusion.Laparoscopic appendectomy was performed in 48% of cases.Percent of 5.34 the patients were treated conservatively with a mean length of stay of 3.98 ± 3.96 d; the relapse rate was 23.1% and the cumulative hospital stay during the study period was 5.46 ± 6.05 d.CONCLUSION The treatment of acute appendicitis in Northern Italy is slowly changing,with the large diffusion of laparoscopic approach; conservative treatment of non-complicated appendicitis is still a neglected option,but rich of promising results. | Marco Ceresoli Alberto Zucchi Niccolò Allievi Asaf Harbi Michele Pisano Giulia Montori Arianna Heyer Gabriela E Nita Luca Ansaloni Federico Coccolini | 2016 | World Journal of Gastrointestinal Surgery2016，8，10： | 14 |
| 6 | Prognostic value of increased carbohydrate antigen in patients with heart failure显示文摘AIM:To study the prognostic value of carbohydrateantigen 125(CA125) and whether it adds prognostic information to N-terminal pro-brain natriuretic peptide(NT-proBNP) in stable heart failure(HF) patients.METHODS:The predictive value of CA125 was retrospectively assessed in 156 patients with stable HF remitted to the outpatient HF unit for monitoring from 2009 to 2011.Patients were included in the study if they had a previous documented episode of HF and received HF treatment.CA125 and NT-proBNP concentrations were measured.The independent association between NT-proBNP or CA125 and mortality was assessed with Cox regression analysis,and their combined predictive ability was tested by the integrated discrimination improvement(IDI) index.RESULTS:The mean age of the 156 patients was 72 ± 12 years.During follow-up(17 ± 8 mo),27 patients died,1 received an urgent heart transplantation and 106 required hospitalization for HF.Higher CA125 values were correlated with outcomes:58 ± 85 KU/L if hospitalized vs 34 ± 61 KU/L if not(P < 0.05),and 94 ± 121 KU/L in those who died or needed urgent heart transplantation vs 45 ± 78 KU/L in survivors(P < 0.01).After adjusting for propensity scores,the highest risk was observed when both biomarkers were elevated vs not elevated(HR = 8.95,95%CI:3.11-25.73; P < 0.001) and intermediate when only NT-proBNP was elevated vs not elevated(HR = 4.15,95%CI:1.41-12.24; P < 0.01).Moreover,when CA125 was added to the clinical model with NT-proBNP,a 4%(P < 0.05) improvement in the IDI was found.CONCLUSION:CA125 > 60 KU/L identified patients in stable HF with poor survival.Circulating CA125 level adds prognostic value to NT-proBNP level in predicting HF outcomes. | Ana B Méndez Jordi Ordonez-Llanos Andreu Ferrero Mariana Noguero Teresa Mir Josefina Mora Antoni Bayes-Genis Sònia Mirabet Juan Cinca Eulàlia Roig | 2014 | World Journal of Cardiology2014，6，4： | 13 |
| 7 | Transcranial Doppler ultrasonography: From methodology to major clinical applications显示文摘Non-invasive Doppler ultrasonographic study of cerebral arteries [transcranial Doppler(TCD)] has been extensively applied on both outpatient and inpatient settings. It is performed placing a low-frequency(≤ 2 MHz) transducer on the scalp of the patient over specific acoustic windows, in order to visualize the intracranial arterial vessels and to evaluate the cerebral blood flow velocity and its alteration in many different conditions. Nowadays the most widespread indication for TCD in outpatient setting is the research of right to left shunting, responsable of so called 'paradoxical embolism', most often due to patency of foramen ovale which is responsable of the majority of cryptogenic strokes occuring in patients younger than 55 years old. TCD also allows to classify the grade of severity of such shunts using the so called 'microembolic signal grading score'. In addition TCD has found many useful applications in neurocritical care practice. It is useful on both adults and children for day-to-day bedside assessment of critical conditions including vasospasm in subarachnoidal haemorrhage(caused by aneurysm rupture or traumatic injury), traumatic brain injury, brain stem death. It is used also to evaluate cerebral hemodynamic changes after stroke. It also allows to investigate cerebral pressure autoregulation and for the clinical evaluation of cerebral autoregulatory reserve. | Antonello D'Andrea Marianna Conte Massimo Cavallaro Raffaella Scarafile Lucia Riegler Rosangela Cocchia Enrica Pezzullo Andreina Carbone Francesco Natale Giuseppe Santoro Pio Caso Maria Giovanna Russo Eduardo Bossone Raffaele Calabrò | 2016 | World Journal of Cardiology2016，8，7： | 10 |
| 8 | Roasting and chlorine leaching of gold-bearing refractory concentrate:Experimental and process analysis显示文摘This paper deals with gold extraction from a refractory concentrate by chlorine leaching.The process considers a pre-treatment of refractory materials by low temperature oxidation carried out with low oxygen concentration.The oxidized material is treated by leaching with brine.After gold adsorption/reduction onto activated carbon,iron and base metals can be precipitated by NaOH.Roasting tests show the necessity to carry out a thermal pre-treatment at least at 550°C to obtain a reduction of sulfur and mercury in the material(50%and 90%,respectively).Highest gold extraction yield(around 93%)is obtained in the leaching test performed with material sample treated at 650°C.This result confrms the necessity to optimize the thermal pre-treatment to improve Au recovery and to reduce chlorine consumption.A comparison with conventional cyanidation confrms that chlorination could be an useful alternative:in fact,gold extraction yield is quite low:57%in non-pre-treated material and 25%in pre-treatment material. | Ida De Michelis Agostino Olivieri Stefano Ubaldini Francesco Ferella Francesca Beolchini Francesco Vegliò | 2013 | International Journal of Mining Science and Technology2013，23，5： | 10 |
| 9 | Treatment strategy for colorectal cancer with resectable synchronous liver metastases:Is any evidence-based strategy possible?显示文摘Fifteen percent to twenty-five percent of patients affected by colorectal cancer presents with liver metastases at diagnosis. In resectable cases, surgery is the only potentially curative treatment and achieves survival rates up to 50% at 5 years. Management is complex, as colorectal resection, liver resection, chemotherapy, and, in locally advanced mid/low rectal tumors, radiotherapy have to be integrated. Modern medical practice usually relies on evidence-based protocols. Levels of evidence for synchronous metastases are poor:published studies include few recent prospective series and several retrospective analyses collecting a limited number of patients across long periods of time. Data are difficult to be generalized and are mainly representative of single centre's experience, biased by local recruitment, indications and surgical technique. In this context, surgeons have to renounce to 'evidence-based medicine' and to adopt a sort of 'experience-based medicine'. Anyway, some suggestions are possible. Simultaneous colorectal and liver resection can be safely performed whenever minor hepatectomies are planned, while a case-by-case evaluation is mandatory in case of more complex procedures. Neoadjuvant chemotherapy is preferentially scheduled for patients with advanced metastatic tumors to assess disease biology and to control lesions. It can be safely performed with primarytumor in situ , even planning simultaneous resection at its end. Locally advanced mid/low rectal tumor represents a further indication to neoadjuvant therapies, even if treatment's schedule is not yet standardized. In summary, several issues have to be solved, but every single HPB centre should define its proper strategy to optimize patient's selection, disease control and safety and completeness of surgery. | Luca Viganò | 2012 | World Journal of Hepatology2012，4，8： | 8 |
| 10 | Cholangiocarcinoma and malignant bile duct obstruction: A review of last decades advances in therapeutic endoscopy显示文摘In the last decades many advances have been achieved in endoscopy, in the diagnosis and therapy of cholangiocarcinoma, however blood test, magnetic resonance imaging, computed tomography scan may fail to detect neoplastic disease at early stage, thus the diagnosis of cholangiocarcinoma is achieved usually at unresectable stage. In the last decades the role of endoscopy has moved from a diagnostic role to an invaluable therapeutic tool for patients affected by malignant bile duct obstruction. One of the major issues for cholangiocarcinoma is bile ducts occlusion, leading to jaundice, cholangitis and hepatic failure. Currently, endoscopy has a key role in the work up of cholangiocarcinoma, both in patients amenable to surgical intervention as well as in those unfit for surgery or not amenable to immediate surgical curative resection owing to locally advanced or advanced disease, with palliative intention. Endoscopy allows successful biliary drainage and stenting in more than 90% of patients with malignant bile duct obstruction, and allows rapid reduction of jaundice decreasing the risk of biliary sepsis. When biliary drainage and stenting cannot be achieved with endoscopy alone, endoscopic ultrasound-guided biliary drainage represents an effective alternative method affording successful biliary drainage in more than 80% of cases. The purpose of this review is to focus on the currently available endoscopic management options in patients with cholangiocarcinoma. | Helga Bertani Marzio Frazzoni Santi Mangiafico Angelo Caruso Mauro Manno Vincenzo Giorgio Mirante Flavia Pigò Carmelo Barbera Raffaele Manta Rita Conigliaro | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，6： | 8 |
| 11 | Clinical significance of NOD2/CARD15 and Toll-like receptor 4 gene single nucleotide polymorphisms in inflammatory bowel disease显示文摘AIM: To evaluate the role of genetic factors in the pathogenesis of Crohn's disease (CD) and ulcerative colitis (UC), we investigated the single nucleotide poly- morphisms (SNPs) of NOD2/CARD15 (R702W, G908R and L1007fi nsC), and Toll-like receptor 4 (TLR4) genes (D299G and T399I) in a selected inflammatory bowel disease (IBD) population coming from Southern Italy. METHODS: Allele and genotype frequencies of NOD2/ CARD15 (R702W, G908R and L1007finsC) and TLR4 (D299G and T399I) SNPs were examined in 133 CD pa-tients, in 45 UC patients, and in 103 healthy controls. A genotype-phenotype correlation was performed. RESULTS: NOD2/CARD15 R702W mutation was sig-nificantly more frequent in CD (9.8%) than in controls (2.4%, P = 0.001) and in UC (2.3%, P = 0.03). No sig-nificant difference was found between UC patients and control group (P > 0.05). In CD and UC patients, no signifi cant association with G908R variant was found. L1007f insC SNP showed an association with CD (9.8%) compared with controls (2.9%, P = 0.002) and UC patients (2.3%, P = 0.01). Moreover, in CD patients, G908R and L1007finsC mutations were significantly associated with different phenotypes compared to CD wild-type patients. No association of IBD with the TLR4 SNPs was found in either cohort (allele frequencies: D299G-controls 3.9%, CD 3.7%, UC 3.4%, P > 0.05; T399I-controls 2.9%, CD 3.0%, UC 3.4%, P > 0.05). CONCLUSION: These findings confirm that, in our IBD patients selected from Southern Italy, the NOD2/ CARD15, but not TLR4 SNPs, are associated with in-creased risk of CD. | Luciana Rigoli Claudio Romano Rosario Alberto Caruso Maria A Lo Presti Chiara Di Bella Vincenzo Procopio Giuseppina Lo Giudice Maria Amorini Giuseppe Costantino Maria D Sergi Caterina Cuppari Giovanna Elisa Calabrò Romina Gallizzi Carmelo Damiano Salpietro Walter Fries | 2008 | World Journal of Gastroenterology2008，14，28： | 8 |
| 12 | Adipose tissue and vascular inflammation in coronary artery disease显示文摘Obesity has become an important public health issue in Western and developing countries,with well known metabolic and cardiovascular complications.In the last decades,evidence have been growing about the active role of adipose tissue as an endocrine organ in determining these pathological consequences.As a consequence of the expansion of fat depots,in obese subjects,adipose tissue cells develope a phenotypic modification,which turns into a change of the secretory output.Adipocytokines produced by both adipocytes and adipose stromal cells are involved in the modulation of glucose and lipid handling,vascular biology and,moreover,participate to the systemic inflammatory response,which characterizes obesity and metabolic syndrome.This might represent an important pathophysiological link with atherosclerotic complications and cardiovascular events.A great number of adipocytokines have been described recently,linking inflammatory mileu and vascular pathology.The understanding of these pathways is crucial not only from a pathophysiological point of view,but also to a better cardiovascular disease risk stratification and to the identification of possible therapeutic targets.The aim of this paper is to review the role of Adipocytokines as a possible link between obesity and vascular disease. | Enrica Golia Giuseppe Limongelli Francesco Natale Fabio Fimiani Valeria Maddaloni Pina Elvira Russo Lucia Riegler Renatomaria Bianchi Mario Crisci Gaetano Di Palma Paolo Golino Maria Giovanna Russo Raffaele Calabrò Paolo Calabrò | 2014 | World Journal of Cardiology2014，6，7： | 8 |
| 13 | Acute appendicitis: What is the gold standard of treatment?显示文摘McBurney’s procedure represented the gold-standard for acute appendicitis until 1981,but nowadays the number of laparoscopic appendectomies has progressively increased since it has been demonstrated to be a safe procedure,with excellent cosmetic results and it also allows a shorter hospitalization,a quicker and less painful postoperative recovery.The aim of this editorial was to perform a review of the literature in order to address controversial issues in the treatment of acute appendicitis. | Cesare Ruffolo Alain Fiorot Giulia Pagura Michele Antoniutti Marco Massani Ezio Caratozzolo Luca Bonariol Francesco Calia di Pinto Nicolò Bassi | 2013 | World Journal of Gastroenterology2013，19，47： | 8 |
| 14 | Long-term outcomes after laparoscopic colectomy显示文摘AIM:To evaluate long-term outcomes in a large series of patients who randomly received laparoscopic or open colorectal resection.METHODS:From February 2000 to December 2004,six hundred sixty-two patients with colorectal disease were randomly assigned to laparoscopic(LPS,n = 330) or open(n = 332) colorectal resection.All patients were analyzed on an intention-to-treat basis.Long-term follow-up was carried out every 6 mo by office visits.In 526 cancer patients five-year overall and disease-free survival were evaluated.Median oncologic follow-up was 96 mo.RESULTS:Eight(4.2%) LPS group patients needed conversion to open surgery.Overall long-term morbidity rate was 7.6%(25/330) in the LPS vs 11.1%(37/332) in the open group(P = 0.17).In cancer patients,fiveyear overall survival was 68.6% in the LPS group and 64.0% in the Open group(P = 0.27).Excluding stage Ⅳ patients,five-year local and distant recurrence rates were 32.5% in the LPS group and 36.8% in the Open group(P = 0.36).Further,no difference in recurrence rate was found when patients were stratified according to cancer stage.CONCLUSION:LPS colorectal resection was associated with a slightly lower incidence of long-term complications than open surgery.No difference between groups was found in overall and disease-free survival rates. | Marco Braga Nicolò Pecorelli Matteo Frasson Andrea Vignali Walter Zuliani Valerio Di Carlo | 2011 | World Journal of Gastrointestinal Oncology2011，3，3： | 8 |
| 15 | Fertility preservation in female cancer patients:a single center experience显示文摘Advances in cancer treatment allow women to be cured and live longer. However, the necessary chemotherapy and radiotherapy regimens have a negative impact on future fertility. Oncofertility has emerged as a new interdisciplinary field to address the issue of gonadotoxicity associated with cancer treatment and to facilitate fertility preservation, including oocyte and ovarian tissue cryopreservation. These fertility issues are often inadequately addressed, and referral rates to oncofertility centers are low. The aim of this study was to report the 3-year experience of the San Raffaele Oncofertility Unit. A total of 96 patients were referred to the Oncofertility Unit for evaluation after the diagnosis of cancer and before gonadotoxic treatment between April 2011 and June 2014. Of the 96 patients, 30(31.2%) were affected by breast cancers, 20(20.8%) by sarcomas, 28(29.2%) by hematologic malignancies, 13(13.5%) by central nervous system cancers, 3(3.1%) by bowel tumors, 1(1.0%) by Wilms' tumor, and 1(1.0%) by a thyroid tumor; 47(49.0%) were referred for oocyte cryopreservation before starting chemotherapy, 20(20.8%) were referred for ovarian tissue cryopreservation, and 29(30.2%) were not recruited. The mean time between the patients' counseling and oocyte retrieval was 15 days(range, 2–37 days). The mean time between the laparoscopic surgery and the beginning of treatment was 4 days(range, 2–10 days). The number of patients who were referred increased over time, whereas the rate of patients who were not recruited decreased, showing an improvement in referrals to the Oncofertility Unit and in the patients' counseling and understanding. Our results indicate that an effective multidisciplinary oncofertility team is necessary for prompt referrals and treatment. | Cristina Sigismondi Enrico Papaleo Paola Viganò Simona Vailati Massimo Candiani Jessica Ottolina Valentina E.

| 16 | Transmission of vector vortex beams in dispersive media显示文摘Scattering phenomena affect light propagation through any kind of medium from free space to biological tissues.Finding appropriate strategies to increase the robustness to scattering is the common requirement in developing both communication protocols and imaging systems.Recently,structured light has attracted attention due to its seeming scattering resistance in terms of transmissivity and spatial behavior.Moreover,correlation between optical polarization and orbital angular momentum(OAM),which characterizes the so-called vector vortex beams(VVBs)states,seems to allow for the preservation of the polarization pattern.We extend the analysis by investigating both the spatial features and the polarization structure of vectorial optical vortexes propagating in scattering media with different concentrations.Among the observed features,we find a sudden swift decrease in contrast ratio for Gaussian,OAM,and VVB modes for concentrations of the adopted scattering media exceeding 0.09%.Our analysis provides a more general and complete study on the propagation of structured light in dispersive and scattering media. | Ilaria Gianani Alessia Suprano Taira Giordani NicolòSpagnolo Fabio Sciarrino Dimitris Gorpas Vasilis Ntziachristos Katja Pinker Netanel Biton Judy Kupferman Shlomi Arnong | 2020 | Advanced Photonics2020，2，3： | 7 |
| 17 | Percutaneous ablation of pancreatic cancer显示文摘Pancreatic ductal adenocarcinoma is a highly aggressive tumor with an overall 5-year survival rate of less than 5%. Prognosis and treatment depend on whether the tumor is resectable or not, which mostly depends on how quickly the diagnosis is made. Chemotherapy and radiotherapy can be both used in cases of nonresectable pancreatic cancer. In cases of pancreatic neoplasm that is locally advanced, non-resectable, but non-metastatic, it is possible to apply percutaneous treatments that are able to induce tumor cytoreduction. The aim of this article will be to describe the multiple currently available treatment techniques(radiofrequency ablation, microwave ablation, cryoablation, and irreversible electroporation), their results, and their possible complications, with the aid of a literature review. | Mirko D'Onofrio Valentina Ciaravino Riccardo De Robertis Emilio Barbi Roberto Salvia Roberto Girelli Salvatore Paiella Camilla Gasparini Nicolò Cardobi Claudio Bassi | 2016 | World Journal of Gastroenterology2016，22，44： | 7 |
| 18 | Reactivation of hepatitis B virus infection in patients with hemolymphoproliferative diseases, and its prevention显示文摘Reactivation of hepatitis B virus(HBV)replication is characterized by increased HBV-DNA serum values of about 1 log or by HBV DNA turning positive if previously undetectable in serum,possibly associated with liver damage and seldom life-threatening.Due to HBV reactivation,hepatitis B surface antigen(HBsAg)-negative/anti-HBc-positive subjects may revert to HBsAg-positive.In patients with hemo-lymphoproliferative disease,the frequency of HBV reactivation depends on the type of lymphoproliferative disorder,the individual's HBV serological status and the potency and duration of immunosuppression.In particular,it occurs in 10%-50%of the HBsAg-positive and in 2%-25%of the HBsAg-negative/anti-HBc-positive,the highest incidences being registered in patients receiving rituximab-based therapy.HBV reactivation can be prevented by accurate screening of patients at risk and by a pharmacological prophylaxis with anti-HBV nucleo(t)sides starting 2-3 wk before the beginning of immunosuppressive treatment and covering the entire period of administration of immunosuppressive drugs and a long subsequent period,the duration of which depends substantially on the degree of immunodepression achieved.Patients with significant HBV replication before immunosuppressive therapy should receive anti-HBV nucleo(t)sides as a long-term(may be life-long)treatment.This review article is mainly directed to doctors engaged every day in the treatment of patients with onco-lymphoproliferative diseases,so that they can broaden their knowledge on HBV infection and on its reactivation induced by the drugs with high immunosuppressive potential that they use in the care of their patients. | Caterina Sagnelli Mariantonietta Pisaturo Federica Calò Salvatore Martini Evangelista Sagnelli Nicola Coppola | 2019 | World Journal of Gastroenterology2019，25，26： | 6 |
| 19 | Rifaximin,but not growth factor 1,reduces brain edema in cirrhotic rats显示文摘AIM:To compare rifaximin and insulin-like growth factor(IGF)-1 treatment of hyperammonemia and brain edema in cirrhotic rats with portal occlusion.METHODS:Rats with CCl4-induced cirrhosis with ascites plus portal vein occlusion and controls were randomized into six groups:Cirrhosis;Cirrhosis + IGF-1;Cirrhosis + rifaximin;Controls;Controls + IGF-1;and Controls + rifaximin.An oral glutamine-challenge test was performed,and plasma and cerebral ammonia,glucose,bilirubin,transaminases,endotoxemia,brain water content and ileocecal cultures were measured and liver histology was assessed.RESULTS:Rifaximin treatment significantly reduced bacterial overgrowth and endotoxemia compared with cirrhosis groups,and improved some liver function parameters(bilirubin,alanine aminotransferase and aspartate aminotransferase).These effects were associated with a significant reduction in cerebral water content.Blood and cerebral ammonia levels,and area-underthe-curve values for oral glutamine-challenge tests were similar in rifaximin-treated cirrhotic rats and control group animals.By contrast,IGF-1 administration failed to improve most alterations observed in cirrhosis.CONCLUSION:By reducing gut bacterial overgrowth,only rifaximin was capable of normalizing plasma and brain ammonia and thereby abolishing low-grade brain edema,alterations associated with hepatic encephalopathy. | Gemmaòdena Mireia Miquel Anna Serafín Amparo Galan Rosa Morillas Ramon Planas Ramon Bartolí | 2012 | World Journal of Gastroenterology2012，18，17： | 6 |
| 20 | Acute alcoholic hepatitis, end stage alcoholic liver disease and liver transplantation: An Italian position statement显示文摘Alcoholic liver disease encompasses a broad spectrum of diseases ranging from steatosis steatohepatitis,fibrosis,and cirrhosis to hepatocellular carcinoma.Forty-four per cent of all deaths from cirrhosis are attributed to alcohol.Alcoholic liver disease is the second most common diagnosis among patients undergoing liver transplantation(LT).The vast majority of transplant programmes(85%)require 6 mo of abstinence prior to transplantation;commonly referred to as the'6-mo rule'.Both in the case of progressive end-stage liver disease(ESLD)and in the case of severe acute alcoholic hepatitis(AAH),not responding to medical therapy,there is a lack of evidence to support a 6-mo sobriety period.It is necessary to identify other risk factors that could be associated with the resumption of alcohol drinking.The'Group of Italian Regions'suggests that:in a case of ESLD with model for end-stage liver disease<19 a 6-mo abstinence period is required;in a case of ESLD,a 3-mo sober period before LT may be more ideal than a 6-mo period,in selected patients;and in a case of severe AAH,not respond-ing to medical therapies(up to 70%of patients die within 6 mo),LT is mandatory,even without achieving abstinence.The multidisciplinary transplant team must include an addiction specialist/hepato-alcohologist.Patients have to participate in self-help groups. | Gianni Testino Patrizia Burra Ferruccio Bonino Francesco Piani Alessandro Sumberaz Roberto Peressutti Andrea Giannelli Castiglione Valentino Patussi Tiziana Fanucchi Ornella Ancarani Giovanna De Cerce Anna Teresa Iannini Giovanni Greco Antonio Mosti Marilena Durante Paola Babocci Mariano Quartini Davide Mioni Sarino Aricò Aniello Baselice Silvia Leone Fabiola Lozer Emanuele Scafato Paolo Borro | 2014 | World Journal of Gastroenterology2014，20，40： | 5 |
