1Adjusting CA19-9 values to predict malignancy in obstructive jaundice:Influence of bilirubin and C-reactive protein显示文摘AIM:To find a possible relationship between inflammation and CA19-9 tumor marker by analyzing data from patients with benign jaundice(BJ) and malignant jaundice(MJ).METHODS:All patients admitted for obstructive jaundice,in the period 2005-2009,were prospectively enrolled in the study,obtaining a total of 102 patients.On admission,all patients underwent complete standard blood test examinations including C-reactive protein(CRP),bilirubin,CA19-9.Patients were considered eligible for the study when they presented obstructive jaundice confirmed by instrumental examinations and increased serum bilirubin levels(total bilirubin > 2.0 mg/dL).The standard cut-off level for CA19-9 was 32 U/mL,whereas for CRP this was 1.5 mg/L.The CA19-9 level was adjusted by dividing it by the value of serum bilirubin or by the CRP value.The patients were divided into 2 groups,MJ and BJ,and after the adjustment a comparison between the 2 groups of patients was performed.Sensitivity,specificity and positive predictive values were calculated before and after the adjustment.RESULTS:Of the 102 patients,51 were affected by BJ and 51 by MJ.Pathologic CA19-9 levels were found in 71.7% of the patients.In the group of 51 BJ patients there were 29(56.9%) males and 22(43.1%) females with a median age of 66 years(range 24-96 years),whereas in the MJ group there were 24(47%) males and 27(53%) females,with a mean age of 70 years(range 30-92 years).Pathologic CA19-9 serum level was found in 82.3% of MJ.CRP levels were pathologic in 66.6% of the patients with BJ and in 49% with MJ.Bilirubin and CA19-9 average levels were significantly higher in MJ compared with BJ(P = 0.000 and P = 0.02),while the CRP level was significantly higher in BJ(P = 0.000).Considering a CA19-9 cut-off level of 32 U/mL,82.3% in the MJ group and 54.9% in the BJ group were positive for CA19-9(P = 0.002).A CA19-9 cut-off of 100 U/mL increases the difference between the two groups:35.3% in BJ and 68.6% in MJ(P = 0.0007).Adjusting the CA19-9 value by dividing it by serum bilirubin level meant that 21.5% in the BJ and 49% in the MJ group remained with a positive CA19-9 value(P = 0.003),while adjusting the CA19-9 value by dividing it by serum CRP value meant that 31.4% in the BJ group and 76.5% in the MJ group still had a positive CA19-9 value(P = 0.000004).Sensitivity,specificity,positive predictive values of CA19-9 > 32 U/mL were 82.3%,45% and 59.1%;when the cutoff was CA19-9 > 100 U/mL they were,respectively,68.6%,64.7% and 66%.When the CA19-9 value was adjusted by dividing it by the bilirubin or CRP values,these became 49%,78.4%,69.4% and 76.5%,68.6%,70.9%,respectively.CONCLUSION:The present study proposes CRP as a new and useful correction factor to improve the diag-nostic value of the CA19-9 tumor marker in patients with cholestatic jaundice.Gaetano La Greca Maria Sofia Rosario Lombardo Saverio Latteri Agostino Ricotta Stefano Puleo Domenico Russello 2012World Journal of Gastroenterology2012,18,31:20

3S100B protein in the gut:The evidence for enteroglial-sustained intestinal inflammation显示文摘Glial cells in the gut represent the morphological and functional equivalent of astrocytes and microglia in the central nervous system (CNS). In recent years, the role of enteric glial cells (EGCs) has extended from that of simple nutritive support for enteric neurons to that of being pivotal participants in the regulation of inflammatory events in the gut. Similar to the CNS astrocytes, the EGCs physiologically express the S100B protein that exerts either trophic or toxic effects depending on its concentration in the extracellular milieu. In the CNS, S100B overexpression is responsible for the initiation of a gliotic reaction by the release of pro-inflammatory mediators, which may have a deleterious effect on neighboring cells. S100B-mediated pro-inflammatory effects are not limited to the brain: S100B overexpression is associated with the onset and maintenance of inflammation in the human gut too. In this review we describe the major features of EGCs and S100B protein occurring in intestinal inflammation deriving from such.Carla Cirillo Giovanni Sarnelli Giuseppe Esposito Fabio Turco Luca Steardo Rosario Cuomo 2011World Journal of Gastroenterology2011,17,10:16
4Laparo-endoscopic “Rendezvous” to treat cholecysto-choledocolithiasis: Effective,safe and simplifies the endoscopist’s work显示文摘AIM: To investigate our clinical experience with combined laparo-endoscopic Rendezvous (RV) for the treatment of patients affected by gallstones and common bile duct (CBD) stones and especially to study the never evaluated opinion of the endoscopist concerning the difficulty of the intraoperative endoscopic procedure during the RV in comparison with standard endoscopic retrograde cholangio-pancreatography (ERCP). METHODS: Eighty consecutive patients affected by cholecystolithiasis and diagnosed or suspected CBD stones were treated with a standardized 'tailored' RV. The relevant technical features, the feasibility, the effectiveness in stone clearance, the safety but also the simple evaluation of difficulty and agreement of the endoscopist were analyzed with a questionnaire. RESULTS: The feasibility was 97.5% and the effectiveness 100% concerning CBD clearance and solution of coexisting problems at the papilla. Minor morbidity was 3.3%, the operating time was prolonged by a mean of 14 min, the mean hospital stay was 3.8 d and only one stone’s recurrence occurred. The endoscopist evaluated the procedure to be simpler than standard ERCP-ES in 81.2% of the cases.CONCLUSION: Simultaneous RV carries higheffectiveness and safety at least comparable to those reported for other options. The endoscopist is very often satisfied with this approach because of the minimization of some steps of the endoscopic procedure and avoidance of relevant iatrogenic risk factors. If the mandatory collaboration between surgeons and endoscopists is guaranteed, this approach can often be preferable for the patient, the surgeon, the endoscopist and the hospital.Gaetano La Greca Francesco Barbagallo Michele Di Blasi Andrea Chisari Rosario Lombardo Rosario Bonaccorso Saverio Latteri Andrea Di Stefano Domenico Russello 2008World Journal of Gastroenterology2008,14,18:15
5S100B protein in tissue development,repair and regeneration显示文摘The Ca 2+-binding protein of the EF-hand type,S100B,exerts both intracellular and extracellular regulatory activities.As an intracellular regulator,S100B is involved in the regulation of energy metabolism,transcription,protein phosphorylation,cell proliferation,survival,differentiation and motility,and Ca 2+ homeostasis,by interacting with a wide array of proteins(i.e.,enzymes,enzyme substrates,cytoskeletal subunits,scaffold/adaptor proteins,transcription factors,ubiquitin E3 ligases,ion channels) in a restricted number of cell types.As an extracellular signal,S100B engages the pattern recognition receptor,receptor for advanced glycation end-products(RAGE),on immune cells as well as on neuronal,astrocytic and microglial cells,vascular smooth muscle cells,skeletal myoblasts and cardiomyocytes.However,RAGE may not be the sole receptor activated by S100B,the protein being able to enhance bFGF-FGFR1 signaling by interacting with FGFR1-bound bFGF in particular cell types.Moreover,extracellular effects of S100B vary depending on its local concentration.Increasing evidence suggests that at the concentration found in extracellular fluids in normal physiological conditions and locally upon acute tissue injury,which is up to a few nM levels,S100B exerts trophic effects in the central and peripheral nervous system and in skeletal muscle tissue thus participating in tissue homeostasis.The present commentary summarizes results implicating intracellular and extracellular S100B in tissue development,repair and regeneration.Guglielmo Sorci Francesca Riuzzi Cataldo Arcuri Claudia Tubaro Roberta Bianchi Ileana Giambanco Rosario Donato 2013World Journal of Biological Chemistry2013,4,1:14
6Spectrum of anemia associated with chronic liver disease显示文摘Anemia of diverse etiology is a common complication of chronic liver diseases. The causes of anemia include acute or chronic gastrointestinal hemorrhage, and hypersplenism secondary to portal hypertension. Severe hepatocellular disease predisposes to hemorrhage because of impaired blood coagulation caused by deficiency of blood coagulation factors synthesized by hepatocytes, and/or thrombocytopenia. Aplastic anemia, which is characterized by pancytopenia and hypocellular bone marrow, may follow the development of hepatitis. Its presentation includes progressive anemia and hemorrhagic manifestations. Hematological complications of combination therapy for chronic viral hepatitis include clinically signif icant anemia, secondary to treatment with ribavirin and/or interferon. Ribavirininduced hemolysis can be reversed by reducing the dose of the drug or discontinuing it altogether. Interferons may contribute to anemia by inducing bone marrow suppression. Alcohol ingestion is implicated in the pathogenesis of chronic liver disease and may contribute to associated anemia. In patients with chronic liver disease, anemia may be exacerbated by defi ciency of folic acid and/or vitamin B12 that can occur secondary to inadequate dietary intake or malabsorption.Rosario Gonzalez-Casas E Anthony Jones Ricardo Moreno-Otero 2009World Journal of Gastroenterology2009,15,37:13
7Vascular endothelial growth factor and tryptase changes after chemoembolization in hepatocarcinoma patients显示文摘AIM: To evaluate vascular endothelial growth factor(VEGF) and tryptase in hepatocellular cancer(HCC)before and after trans-arterial chemoembolization(TACE).METHODS: VEGF and tryptase serum concentrations were assessed from 71 unresectable HCC patients before and after hepatic TACE performed by binding DC-Beads?to doxorubicin. VEGF levels were examined for each serum sample using the Quantikine Human VEGF-enzyme-linked immuno-absorbent assay(ELISA),whereas tryptase serum concentrations were assessed for each serum sample by means of fluoro-enzyme immunoassay(FEIA) using the Uni-CAP100 tool.Differences between serum VEGF and tryptase values before and after TACE were evaluated using Student t test. Person's correlation was used to assess the degree of association between the two variables.RESULTS: VEGF levels and serum tryptase in HCCpatients before TACE had a mean value and standard deviation(SD) of 114.31 ± 79.58 pg/mL and 8.13± 3.61 μg/L, respectively. The mean levels and SD of VEGF levels and serum tryptase in HCC patients after TACE were 238.14 ± 109.41 pg/mL and 4.02 ±3.03 μg/L. The changes between the mean values of concentration of VEGF and tryptase before treatment and after treatment was statistically significant(P <0.000231 and P < 0.00124, by Wilcoxon-Mann-Whitney respectively). A significant correlation between VEGF levels before and after TACE and between tryptase levels before and after TACE was demonstrated(r =0.68, P = 0.003; r = 0.84, P = 0.000 respectively).CONCLUSION: Our pilot results suggest that the higher serum VEGF levels and the lower tryptase levels following TACE may be potential biomarkers changing in response to therapy.Girolamo Ranieri Michele Ammendola Ilaria Marech Annamaria Laterza Ines Abbate Caroline Oakley Angelo Vacca Rosario Sacco Cosmo Damiano Gadaleta 2015World Journal of Gastroenterology2015,21,19:13
8基于2002-2018年MODIS数据的黄海叶绿素a时空变化研究显示文摘浮游植物作为食物链的基础,对海洋生态系统具有重要影响。黄海作为我国重要的渔场,渔业资源面临枯竭的危险,因此对该区浮游植物进行研究具有重要意义。叶绿素a浓度是反映浮游植物生物量的重要指标。利用谷歌地球引擎平台对2002-2018年的MODIS Aqua叶绿素a浓度数据进行处理,并研究其时空分布与变化特征,然后结合区域气候、水文与地理特征以及海洋表面温度、风速、盐度、光合有效辐射和混合层厚度数据分析了其分布与变化的原因。研究发现:受陆源营养物质输入、近岸上升流以及黄海中央冷水团影响,叶绿素a浓度分布呈现由近岸向黄海中部递减特征;在季风、气候、水文的控制下,受风速、海洋表面温度、光合有效辐射、中央冷水团的影响,叶绿素a浓度的最大值出现在4月份,而最小值出现在6、7月份;受苏北沿岸海域海水污染和水体富营养化影响,沿岸海域盐度明显增加,海州湾叶绿素a浓度增速较大;影响黄海叶绿素a浓度变化的环境因子较复杂,除了部分月份存在显著的相关影响因子外,在全年和各季中不存在主导影响因子。田洪阵 刘沁萍 Joaquim I.Goes Helga do Rosario Gomes 杨萌萌 2020海洋通报2020,39,1:11
9Multimodality imaging in apical hypertrophic cardiomyopathy显示文摘Apical hypertrophic cardiomyopathy(AHCM) is a relatively rare morphologic variant of HCM in which the hypertrophy of myocardium is localized to the left ventricular apex. Symptoms of AHCM might vary from none to others mimic coronary artery disease including acute coronary syndrome, thus resulting in inappropriate hospitalization. Transthoracic echocardiography is the firstline imaging technique for the diagnosis of hypertrophic cardiomyopathies. However, when the hypertrophy of the myocardium is localized in the ventricular apex might results in missed diagnosis. Aim of this paper is to review the different imaging techniques used for the diagnosis of AHCM and their role in the detection and comprehension of this uncommon disease.Rosario Parisi Francesca Mirabella Gioel Gabrio Secco Rossella Fattori 2014World Journal of Cardiology2014,6,9:11
10Irritable bowel syndrome and food interaction显示文摘Irritable bowel syndrome(IBS) is one of the most common gastrointestinal disorders in Western countries. Despite the high prevalence of this disorders, the therapeutic management of these patients is often unsatisfactory. A number of factors have been suggested to be involved in the pathogenesis of IBS, including impaired motility and sensitivity, increased permeability, changes in the gut microbiome and alterations in the brain-gut axis. Also food seems to play a critical role: the most of IBS patients report the onset or the exacerbation of their symptoms after the meals. Recently, an increasing attention has been paid to the role of food in IBS. In this review we summarize the most recent evidences about the role of diet on IBS symptoms. A diet restricted in fermentable, poorly absorbed carbohydrates and sugar alcohols has beneficial effects on IBS symptoms. More studies are needed to improve our knowledge about the relationship between food and IBS. However, in the foreseeable future, dietary strategies will represent one of the key tools in the therapeutic management of patients with IBS.Rosario Cuomo Paolo reozzi Francesco Paolo Zito Valentina Passananti Giovanni De Carlo Giovanni Sarnelli 2014World Journal of Gastroenterology2014,20,27:11

12Liver resection versus radiofrequency ablation in the treatment of cirrhotic patients with hepatocellular carcinoma显示文摘BACKGROUND: Hepatocellular carcinoma is the most common type of primary liver tumor and its incidence is increasing worldwide. The study aimed to compare patients subjected to liver resection or radiofrequency ablation. METHODS: One hundred and forty cirrhotic patients in stage A or B of Child-Pugh with single nodular or multinodular hepatocellular carcinoma were included in this retrospective study. Among them, 87 underwent surgical resection, and 53 underwent percutaneous radiofrequency ablation. Patient charac-teristics, survival, and recurrence-free survival were analyzed. RESULTS: Recurrence-free survival was longer in the resection group in comparison to the radiofrequency group with a median recurrence-free time of 36 versus 26 months, respectively (P=0.01, HR=1.52, 95% CI: 1.05-2.25). In the resection group, median survival was 46 months, with the 1-, 3- and 5-year survival rates of 89.7%, 72.4% and 40.2%. In the radiofrequency group, median survival was 32 months, with the 1-, 3- and 5-year survival rates of 83.0%, 43.4% and 22.6% (P<0.01). CONCLUSIONS: Surgical resection improves the overall survival and recurrence-free survival in comparison with radiofrequency ablation. New evidences are needed to define the real role of the percutaneous technique as an alternative to surgery.Amilcare Parisi Jacopo Desiderio Stefano Trastulli Elisa Castellani Rosario Pasquale Roberto Cirocchi Carlo Boselli Giuseppe Noya 2013Hepatobiliary & Pancreatic Diseases International2013,12,3:8
13Clinical 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 2008World Journal of Gastroenterology2008,14,28:8
14Outcome of nonerosive gastro-esophageal reflux disease patients with pathological acid exposure显示文摘AIM: To assess the management and outcome of nonerosive gastro-esophageal reflux disease (NERD) patients who were identified retrospectively, after a 5-year follow-up.METHODS: We included patients with gastro-esophageal reflux disease (GERD) symptoms who had a negative endoscopy result and pathological 24-h esophageal pH-monitoring while off therapy. We interviewed them after an average period of 5 years (range 3.5-7 years) by means of a structured questionnaire to assess presence of GERD symptoms, related therapy, updated en-doscopic data and other features. We assessed predictors of esophagitis development by means of univariate and multivariate statistical analysis.RESULTS: 260 patients (137 women) were included. Predominant GERD symptoms were heartburn andregurgitation in 103/260 (40%). 70% received a maintenance treatment, which was proton pump inhibitor (PPI) in 55% of cases. An average number of 1.5 symptomatic relapses per patient/year of follow-up were observed. A progression to erosive gastro-esophageal reflux disease (ERD) was found in 58/193 (30.0%) of patients undergoing repeat endoscopy; 72% of these were Los Angeles grade A-B. CONCLUSION: This study shows that progression to ERD occurs in about 5% of NERD cases per year, despite therapy. Only two factors consistently and independently influence progression: smoking and absence of PPI therapy.Fabio Pace Stefano Pallotta Gianpiero Manes Annalisa de Leone Patrizia Zentilin Luigi Russo Vincenzo Savarino Matteo Neri Enzo Grossi Rosario Cuomo 2009World Journal of Gastroenterology2009,15,45:8

16近20年渤海叶绿素a浓度时空变化显示文摘浮游植物作为食物链的基础,对海洋生态系统具有重要作用。渤海作为我国最大的内海和重要渔业生物的产卵场、育幼场和索饵场,该区浮游植物研究具有重要意义。叶绿素a浓度是反映浮游植物生物量的重要指标。利用Google Earth Engine平台,对1997–2010年的宽视场海洋观测传感器(SeaWiFS)叶绿素a浓度数据和2002–2018年的水色卫星中分辨率成像光谱仪传感器(MODISAqua)叶绿素a浓度数据进行合并,并研究其时空变化特征。研究表明,近20年来,渤海全年叶绿素a浓度增加了14.1%,且增加显著。叶绿素a浓度在所有季节都呈现增加趋势;除11月外,其他各月都呈现稳定或增加趋势。从滦河入河口沿岸至渤海海峡的渤海中部,叶绿素a浓度增加较明显。同时也分析了海洋表面温度、风速和降水量数据。夏季渤海周边区域降水量和风速增加以及秋季海表温度的降低都有助于同季叶绿素a浓度的升高。渤海浮游植物可能受陆源营养物质输入影响较大。田洪阵 刘沁萍 Joaquim I.Goes Helga do Rosario Gomes 杨萌萌 2019海洋学报2019,41,8:8
17Effect of phacoemulsification on intraocular pressure in patients with primary open angle glaucoma and pseudoexfoliation glaucoma显示文摘AIM: To compare the effect of phacoemulsification on intraocular pressure(IOP) in patients with primary open angle glaucoma(POAG) and pseudoexfoliation glaucoma(PXG). METHODS: A retrospective comparative case series conducted at the Glaucoma Department at the Association to Prevent Blindness in Mexico. The study enrolled consecutive patients having phacoemulsification with intraocular lens(IOL) implantation and a diagnosis of POAG or PXG. Data about IOP values and number of glaucoma medications used was collected at baseline, 1, 3, 6 and 12 mo postoperatively. RESULTS: The study enrolled 88 patients(88 eyes). After phacoemulsification, there was a statistically significant reduction in IOP values and glaucoma medications use compared to baseline in both POAG and PXG patients(P<0.001). In the POAG group, a 20% decrease in IOP values was evidenced, and a 56.5% reduction in the number of medications used at the one-year follow-up. The PXG group showed a 20.39%, and a 34.46% decrease in IOP and number of medications used, respectively. A significant difference in the mean ΔIOP(postoperative changes in IOP) was evidenced between groups(P=0.005). The reduction of the postsurgical IOP mean values in both groups, the POAG group showed a greater reduction in IOP values compared to the PXG group.CONCLUSION: In both types of glaucoma, phacoemulsification cataract surgery can result in a significant IOP reduction(20%) over a 12 mo follow-up period. The number of medications used is also significantly reduced up to 12 mo after surgery, especially in the PXG group.Jesus Jimenez-Roman Gabriel Lazcano-Gomez Karina Martínez-Baez Mauricio Turati Rosario Gulías-Canizo Luis F.Hernández-Zimbrón Lenin Ochoa-De la Paz Rubén Zamora Roberto Gonzalez-Salinas 2017International Journal of Ophthalmology(English edition)2017,10,9:7
18Nano albumin bound-paclitaxel in pancreatic cancer: Current evidences and future directions显示文摘Pancreatic cancer(PDAC) is an aggressive and chemoresistant disease, representing the fourth cause of cancer related deaths in western countries. Majority of patients have unresectable, locally advanced or metastatic disease at time of diagnosis and the 5-year survival rate in these conditions is extremely low. For more than a decade gemcitabine has been the cornerstone of metastatic PDAC treatment, although survival benefit was very poor. PDAC cells are surrounded by an intense desmoplastic reaction that may create a barrier to the drugs penetration within the tumor. Recently PDAC stroma has been addressed as a potential therapeutic target. Nano albumin bound(Nab)-paclitaxel is an innovative molecule depleting tumor stroma, through interaction between albumin and secreted protein acidic and rich in cysteine. Addition of nab-paclitaxel to gemcitabine has showed activity and efficacy in metastatic PDAC first-line treatment improving survival and overall response rate vs gemcitabine alone in the MPACT phase Ⅲ study. This combination represents one of the standards of care in advanced PDAC therapy and is suitable to a broader spectrum of patients compared to other schedules. Nab-paclitaxel is under investigation as a backbone of chemotherapy in novel combinations with target agents or immunotherapy in locally advanced or metastatic PDAC. In this article, we provide an updated and critical overview about the role of nab-paclitaxel in PDAC treatment based on the latest advances in preclinical and clinical research. Furthermore, we focus on the use of nab-paclitaxel within the context of metastatic PDAC treatment landscape and we discuss about future implications in the light of current clinical ongoing trials.Guido Giordano Massimo Pancione Nunzio Olivieri Pietro Parcesepe Marianna Velocci Tania Di Raimo Luigi Coppola Giuseppe Toffoli Mario Rosario D’Andrea 2017World Journal of Gastroenterology2017,23,32:7
19Characterization of hepatitis B virus X gene quasispecies complexity in mono-infection and hepatitis delta virus superinfection显示文摘Hepatitis delta virus(HDV) seems to strongly suppress hepatitis B virus(HBV)replication, although little is known about the mechanism of this interaction. Both these viruses show a dynamic distribution of mutants, resulting in viral quasispecies. Next-generation sequencing is a viable approach for analyzing the composition of these mutant spectra. As the regulatory hepatitis B X protein(HBx) is essential for HBV replication, determination of HBV X gene(HBX)quasispecies complexity in HBV/HDV infection compared to HBV monoinfection may provide information on the interactions between these two viruses.AIM To compare HBV quasispecies complexity in the HBX 5' region between chronic hepatitis delta(CHD) and chronic HBV mono-infected patients.METHODS Twenty-four untreated patients were included: 7/24(29.2%) with HBeAgnegative chronic HBV infection(CI, previously termed inactive carriers), 8/24(33.3%) with HBeAg-negative chronic hepatitis B(CHB) and 9/24(37.5%) with CHD. A serum sample from each patient was first tested for HBV DNA levels.The HBX 5' region [nucleotides(nt) 1255-1611] was then PCR-amplified for subsequent next-generation sequencing(MiSeq, Illumina, United States). HBV quasispecies complexity in the region analyzed was evaluated using incidencebased indices(number of haplotypes and number of mutations), abundancebased indices(Hill numbers of order 1 and 2), and functional indices(mutation frequency and nucleotide diversity). We also evaluated the pattern of nucleotide changes to investigate which of them could be the cause of the quasispecies complexity.RESULTS CHB patients showed higher median HBV-DNA levels [5.4 logIU/mL,interquartile range(IQR) 3.5-7.9] than CHD(3.4 logIU/mL, IQR 3-7.6)(P = n.s.)or CI(3.2 logIU/mL, IQR 2.3-3.5)(P < 0.01) patients. The incidence and abundance indices indicated that HBV quasispecies complexity was significantly greater in CI than CHB. A similar trend was observed in CHD patients, although only Hill numbers of order 2 showed statistically significant differences(CHB2.81, IQR 1.11-4.57 vs CHD 8.87, 6.56-11.18, P = 0.038). There were no significant differences in the functional indices, but CI and CHD patients also showed a trend towards greater complexity than CHB. No differences were found for any HBV quasispecies complexity indices between CHD and CI patients. G-to-A and C-to-T nucleotide changes, characteristic of APOBEC3 G, were higher in CHD and CI than in CHB in genotype A haplotypes, but not in genotype D. The proportion of nt G-to-A vs A-to-G changes and C-to-T vs T-to-C changes in genotype A and D haplotypes in CHD patients showed no significant differences. In CHB and CI the results of these comparisons were dependent on HBV genotype.CONCLUSION The lower-replication CHD and CI groups show a trend to higher quasispecies complexity than the higher-replication CHB group. The mechanisms associated with this greater complexity require elucidation.Cristina Godoy David Tabernero Sara Sopena Josep Gregori Maria Francesca Cortese Carolina González Rosario Casillas Mar?al Yll Ariadna Rando Rosa López-Martínez Josep Quer Gloria González-Aseguinolaza Rafael Esteban Mar Riveiro-Barciela Maria Buti Francisco Rodríguez-Frías 2019World Journal of Gastroenterology2019,25,13:6
20Cell-block procedure in endoscopic ultrasound-guided-fine-needle-aspiration of gastrointestinal solid neoplastic lesions显示文摘In the present review we have analyzed the clinical applications of endoscopic ultrasound-guided-fineneedle-aspiration(EUS-FNA) and the methodological aspects obtained by cell-block procedure(CBP) in the diagnostic approach to the gastrointestinal neoplastic pathology. CBP showed numerous advantages in comparison to the cytologic routine smears; in particular, better preservation of cell architecture, achievement of routine haematoxylin-eosin staining equivalent to histological slides and possibility to perform immunohistochemistry or molecular analyses represented the most evident reasons to choose this method. Moreover, by this approach, the differential diagnosis of solid gastrointestinal neoplasias may be more easily achieved and the background of contaminant nonneoplastic gastrointestinal avoided. Finally, biological samples collected by EUS-FNA CBP-assisted should be investigated in order to identify and quantify further potential molecular markers.Antonio Ieni Valeria Barresi Paolo Todaro Rosario Alberto Caruso Giovanni Tuccari 2015World Journal of Gastrointestinal Endoscopy2015,7,11:6
