| 1 | Efficacy, risk factors and complications of endoscopic polypectomy: Ten year experience at a single center显示文摘AIM: To examine the efficacy and complications of colonoscopic resection of colorectal polypoid lesions. METHODS: We retrospectively reviewed 1354 polypectomies performed on 1038 patients over a ten- year period. One hundred and sixty of these were performed for large polyps, those measuring ≥ 20 mm. Size, shape, location, histology, the technique of polypectomy used, complications, drugs assumption and associated intestinal or extra intestinal diseases were analyzed. For statistical analysis, the Pearson χ2 test, NPC test and a Binary Logistic Regression were used. RESULTS: The mean patient age was 65.9 ± 12.4 years, with 671 men and 367 women. The mean size of polyps removed was 9.45 ± 9.56 mm while the size of large polyps was 31.5 ± 10.8 mm. There were 388 pedunculated and 966 sessile polyps and the most common location was the sigmoid colon (41.3%). The most frequent histology was tubular adenoma (55.9%) while for the large polyps was villous (92/160 -57.5%). Coexistent malignancy was observed in 28 polyps (2.1%) and of these, 20 were large polyps. There were 17 procedural bleeding (1.3%) and one perforation. The statistical analysis showed that cancer is correlated to polyp size (P < 0.0001); sessile shape (P < 0.0001) and bleeding are correlated to cardiac disease (P = 0.034), tubular adenoma (P = 0.016) and polyp size.CONCLUSION: The endoscopic resection is a simple and safe procedure for removing colon rectal neoplastic lesions and should be considered the treatment of choice for large colorectal polyps. The polyp size is an important risk factor for malignancy and for bleeding. | Pierluigi Consolo Carmelo Luigiano Giuseppe Strangio Maria Grazia Scaffidi Giuseppa Giacobbe Giovanna Di Giuseppe Agata Zirilli Luigi Familiari | 2008 | World Journal of Gastroenterology2008，14，15： | 33 |
| 2 | Pediatric non-alcoholic fatty liver disease: Recent solutions, unresolved issues, and future research directions显示文摘Non-alcoholic fatty liver disease(NAFLD) in children is becoming a major health concern. A 'multiple-hit' pathogenetic model has been suggested to explain the progressive liver damage that occurs among children with NAFLD. In addition to the accumulation of fat in the liver, insulin resistance(IR) and oxidative stress due to genetic/epigenetic background, unfavorable lifestyles, gut microbiota and gut-liver axis dysfunction, and perturbations of trace element homeostasis have been shown to be critical for disease progression and the development of more severe inflammatory and fibrotic stages [non-alcoholic steatohepatitis(NASH)]. Simple clinical and laboratory parameters, such as age, history, anthropometrical data(BMI and waist circumference percentiles), blood pressure, surrogate clinical markers of IR(acanthosis nigricans), abdominal ultrasounds, and serum transaminases, lipids and glucose/insulin profiles, allow a clinician to identify children with obesity and obesity-related conditions, including NAFLD and cardiovascular and metabolic risks. A liver biopsy(the 'imperfect' gold standard) is required for a definitive NAFLD/NASH diagnosis, particularly to exclude other treatable conditions or when advanced liver disease is expected on clinical and laboratory grounds and preferably prior to any controlled trial of pharmacological/surgical treatments. However, a biopsy clearly cannot represent a screening procedure. Advancements in diagnostic serum and imaging tools, especially for the non-invasive differentiation between NAFLD and NASH, have shown promising results, e.g., magnetic resonance elastography. Weight loss and physical activity should be the first option of intervention.Effective pharmacological treatments are still under development; however, drugs targeting IR, oxidative stress, proinflammatory pathways, dyslipidemia, gut microbiota and gut liver axis dysfunction are an option for patients who are unable to comply with the recommended lifestyle changes. When morbid obesity prevails, bariatric surgery should be considered. | Maria Grazia Clemente Claudia Mandato Marco Poeta Pietro Vajro | 2016 | World Journal of Gastroenterology2016，22，36： | 32 |

| 4 | 小角弹性光散射粒径测量技术与准确性验证显示文摘改变了用中心有孔的环形光电元件接收前向散射光的传统做法,选择采用高灵敏度、低噪声、高分辨率带冷却的CCD采集散射光。采用光导纤维使透射光导出光轴,从CCD采集到的图像得到光强随散射角变化的分布曲线,用米氏散射程序反算出粒径分布;采用CCD为接收设备提高了测量系统的灵敏度和角度分辨率,使测量稀薄液雾或悬浊液的粒径分布成为可能。尽管激光散射粒径测量方法从测量原理上看更加准确,但此测量技术不是利用颗粒的放大成像确定粒径,不直观,通常需要验证激光粒径测量结果的准确性,常采用经其他光学方法测量过的标准粒子验证。提出了一种非光学的准确性验证方法,即利用单分散液滴串发生器产生的大小可控的等直径、等间距液滴串来验证小角弹性光散射粒径测量系统的准确性。 | 孙晗 Grazia Lamanna Bernhard Weigand | 2013 | 中国激光2013，40，3： | 7 |
| 5 | Role of nitric oxide in the impairment of circular muscle contractility of distended, uninflamed mid-colon in TNBS-induced acute distal colitis in rats显示文摘AIM: To evaluate the role of nitric oxide (NO) in the motor disorders of the dilated uninflamed mid-colon (DUMC)from trinitrobenzene sulfonic acid (TNBS)-induced acute distal colitis in rats.METHODS: Colitis was induced in male Sprague-Dawley rats by a single intracolonic administration of TNBS.Control rats received an enema of 0.9% saline. The rats were killed 48 h after TNBS or saline administration.Macroscopic and histologic lesions of the colon were evaluated. Myeloperoxidase (MPO) and nitric oxide synthase (NOS) activity were measured on the colonic tissue. In TNBS rats, we evaluated spontaneous and evoked contractile activity in circular muscle strips derived from DUMC in comparison to the same colonic segment of control rats, both in the presence and in the absence of a non-selective NOS isoforms inhibitor N-nitro-Larginine (L-NNA). Pharmacological characterization of electric field stimulation (EFS)-evoked contractile responses was also performed.RESULTS: In TNBS rats, the distal colon showed severe histological lesions and a high MPO activity, while the DUMC exhibited normal histology and MPO activity.Constitutive NOS activity was similar in TNBS and control rats, whereas inducible NOS activity was significantly increased only in the injured distal colon of TNBS rats.Isometrically recorded mechanical activity of circular muscle strips from DUMC of TNBS rats showed a marked reduction of the force and frequency of spontaneous contractions compared to controls, as well as of the contractile responses to a contracting stimulus. In the presence of L-NNA, the contractile activity and responses displayed a significantly greater enhancement compared to controls. The pharmacological characterization of EFS contractile responses showed that a cooperative-like interaction between cholinergic muscarinic and tachykinergic neurokinin 1 and 2 receptors mediated transmission in DUMC of TNBS rats vs a simple additive interaction in controls.CONCLUSION: The results of this study show that, during TNBS-induced acute distal colitis, circular muscle intrinsic contractile mechanisms and possible enteric neural excitatory activity are inhibited in the distended uninflamed mid-colon. Suppression of NO synthesis markedly improves spontaneous and evokes muscle contractions, in spite of any evident change in local NO activity. | Luciano Onori Annalisa Aggio Simona D'Alo' Paola Muzi Maria Grazia Cifone Gabriella Mellillo Rachele Ciccocioppo Gennaro Taddei Giuseppe Frieri Giovanni Latella | 2005 | World Journal of Gastroenterology2005，11，36： | 7 |
| 6 | Neoadjuvant therapy in the treatment of hilar cholangiocarcinoma:Review of the literature显示文摘Cholangiocarcinoma(CCA)is a malignant tumor of the biliary system and includes,according to the anatomical classification,intra hepatic CCA(iCCA),hilar CCA(hCCA)and distal CCA(dCCA).Hilar CCA is the most challenging type in terms of diagnosis,treatment and prognosis.Surgery is the only treatment possibly providing long-term survival,but only few patients are considered resectable at the time of diagnosis.In fact,tumor’s extension to segmentary or subsegmentary biliary ducts,along with large lymph node involvement or intrahepatic metastases,precludes the surgical approach.To achieve R0 margins is mandatory for the disease-free survival and overall survival.In case of unresectable locally advanced hCCA,radiochemotherapy(RCT)as neoadjuvant treatment demonstrated to be a therapeutic option before either hepatic resection or liver transplantation.Before liver surgery,RCT is believed to enhance the R0 margins rate.For patients meeting the Mayo Clinic criteria,RCT prior to orthotopic liver transplant(OLT)has proved to produce acceptable 5-years survivals.In this review,we analyze the current role of neoadjuvant RCT before resection as well as before OLT. | Fabio Frosio Federico Mocchegiani Grazia Conte Enrico Dalla Bona ANDrea Vecchi Daniele Nicolini Marco Vivarelli | 2019 | World Journal of Gastrointestinal Surgery2019，11，6： | 7 |

| 8 | Efficient RT-QuIC seeding activity for α-synuclein in olfactory mucosa samples of patients with Parkinson’s disease and multiple system atrophy显示文摘Background:Parkinson’s disease(PD)is a neurodegenerative disorder whose diagnosis is often challenging because symptoms may overlap with neurodegenerative parkinsonisms.PD is characterized by intraneuronal accumulation of abnormalα-synuclein in brainstem while neurodegenerative parkinsonisms might be associated with accumulation of eitherα-synuclein,as in the case of Multiple System Atrophy(MSA)or tau,as in the case of Corticobasal Degeneration(CBD)and Progressive Supranuclear Palsy(PSP),in other disease-specific brain regions.Definite diagnosis of all these diseases can be formulated only neuropathologically by detection and localization ofα-synuclein or tau aggregates in the brain.Compelling evidence suggests that trace-amount of these proteins can appear in peripheral tissues,including receptor neurons of the olfactory mucosa(OM).Methods:We have set and standardized the experimental conditions to extend the ultrasensitive Real Time Quaking Induced Conversion(RT-QuIC)assay for OM analysis.In particular,by using human recombinantα-synuclein as substrate of reaction,we have assessed the ability of OM collected from patients with clinical diagnoses of PD and MSA to induceα-synuclein aggregation,and compared their seeding ability to that of OM samples collected from patients with clinical diagnoses of CBD and PSP.Results:Our results showed that a significant percentage of MSA and PD samples inducedα-synuclein aggregation with high efficiency,but also few samples of patients with the clinical diagnosis of CBD and PSP caused the same effect.Notably,the final RT-QuIC aggregates obtained from MSA and PD samples owned peculiar biochemical and morphological features potentially enabling their discrimination.Conclusions:Our study provide the proof-of-concept that olfactory mucosa samples collected from patients with PD and MSA possess important seeding activities forα-synuclein.Additional studies are required for(i)estimating sensitivity and specificity of the technique and for(ii)evaluating its application for the diagnosis of PD and neurodegenerative parkinsonisms.RT-QuIC analyses of OM and cerebrospinal fluid(CSF)can be combined with the aim of increasing the overall diagnostic accuracy of these diseases,especially in the early stages. | Chiara Maria Giulia De Luca Antonio Emanuele Elia Sara Maria Portaleone Federico Angelo Cazzaniga Martina Rossi Edoardo Bistaffa Elena De Cecco Joanna Narkiewicz Giulia Salzano Olga Carletta Luigi Romito Grazia Devigili Paola Soliveri Pietro Tiraboschi Giuseppe Legname Fabrizio Tagliavini Roberto Eleopra Giorgio Giaccone Fabio Moda | 2019 | Translational Neurodegeneration2019，8，1： | 5 |
| 9 | Vertical hepatitis C virus transmission:Main questions and answers显示文摘Hepatitis C virus(HCV) affects about 3% of the world's population and peaks in subjects aged over 40 years. Its prevalence in pregnant women is low(1%-2%) in most western countries but drastically increases in women in developing countries or with high risk behav-iors for blood-transmitted infections. Here we review clinical, prognostic and therapeutic aspects of HCV in-fection in pregnant women and their offspring infected through vertical transmission. Pregnancy-related im-mune weakness does not seem to affect the course of acute hepatitis C but can affect the progression of chronic hepatitis C. In fact, postpartum immune res-toration can exacerbate hepatic inflammation, thereby worsening the liver disease, particularly in patients with liver cirrhosis. HCV infection increases the risk of gestational diabetes in patients with excessive weight gain, premature rupture of membrane and caesarean delivery. Only 3%-5% of infants born to HCV-positive mothers have been infected by intrauterine or perinatal transmission. Maternal viral load, human immunode-ficiency virus coinfection, prolonged rupture of mem-branes, fetal exposure to maternal infected blood con-sequent to vaginal or perineal lacerations and invasive monitoring of fetus increase the risk of viral transmis-sion. Cesarean delivery and breastfeeding increases the transmission risk in HCV/human immunodeficiency virus coinfected women. The consensus is not to offer antivi-ral therapy to HCV-infected pregnant women because it is based on ribavirin(pregnancy category X) because of its embryocidal and teratogenic effects in animal spe-cies. In vertically infected children, chronic C hepatitis is often associated with minimal or mild liver disease and progression to liver cirrhosis and hepatocarcinoma is lower than in adults. Infected children may be treated after the second year of life, given the adverse effects of current antiviral agents. | Grazia Tosone Alberto Enrico Maraolo Silvia Mascolo Giulia Palmiero Orsola Tambaro Raffaele Orlando | 2014 | World Journal of Hepatology2014，6，8： | 5 |
| 10 | Giant splenic artery aneurysm presenting with massive upper gastrointestinal bleeding:A case report and review of literature显示文摘BACKGROUND Splenic artery aneurysm(SAA)and pseudoaneurysm are rare vessel’s lesions.Pseudoaneurysm is often symptomatic and secondary to pancreatitis or trauma.True SAA is the most common aneurysm of visceral vessels.In contrast to pseudoaneurysm,SAA is usually asymptomatic until the rupture,with high mortality rate.The clinical onset of SSA’s rupture is a massive life-threatening bleeding with hemodynamic instability,usually into the free peritoneal space and more rarely into the gastrointestinal tract.CASE SUMMARY We describe the case of a 35-year-old male patient,with negative past medical history,who presented to the emergency department for massive upper gastrointestinal bleeding,severe anemia and hypotension.An esophagogastroduodenoscopy performed in emergency showed a gastric bulging in the greater curvature/posterior wall with a small erosion on its surface,with a visible vessel,but no active bleeding.Endoscopic injection therapy with cyanoacrylate glue was performed.Urgent contrast-enhanced computed tomography was carried out due to the clinical scenario and the unclear endoscopic aspect:The radiological examination showed a giant SAA which was adherent to posterior stomach wall,and some smaller aneurysms of the left gastric and ileocolic artery.Because of the high risk of a two-stage rupture of the giant SAA with dramatic outcome,the patient underwent immediate open surgery with aneurysmectomy,splenectomy and distal pancreatectomy with a good postoperative outcome.CONCLUSION The management of a ruptured giant SAA into the stomach can be successful with surgical approach. | Francesco Panzera Riccardo Inchingolo Marina Rizzi Assunta Biscaglia Maria Grazia Schievenin Emilia Tallarico Giancarlo Pacifico Beatrice Di Venere | 2020 | World Journal of Gastroenterology2020，26，22： | 4 |
| 11 | Antiviral therapy for hepatitis C: Has anything changed for pregnant/lactating women?显示文摘Hepatitis C virus(HCV) affects about 3% of the world'spopulation, with the highest prevalence in individuals under 40. The prevalence in pregnant women varies with geographical distribution(highest in developing countries). Prevalence also increases in sub-populations of women at high risk for blood-transmitted infections. HCV infection in pregnancy represents a non-negligible problem. However, most of the past antiviral regimens cannot be routinely offered to pregnant or breastfeeding women because of their side effects. We briefly reviewed the issue of treatment of HCV infection in pregnant/breastfeeding women focusing on the effects of the new direct-acting antivirals on fertility, pregnancy and lactation in animal studies and on the potential risk for humans based on the pharmacokinetic properties of each drug. Currently, all new therapy regimens are contraindicated in this setting because of lack of sufficient safety information and adequate measures of contraception are still routinely recommended for female patients of childbearing potential. | Anna Maria Spera Tarek Kamal Eldin Grazia Tosone Raffaele Orlando | 2016 | World Journal of Hepatology2016，8，12： | 4 |
| 12 | Deep endometriosis with pericolic lymph node involvement: A case report and literature review显示文摘Deep infiltrating endometriosis is an often-painful disorder affecting women during their reproductive years that usually involves the structures of the pelvis and frequently the gastrointestinal tract.We present the case of a 37-year-old female patient with an endometrial growth on the sigmoid colon wall causing pain,diarrhea and the presence of blood in the feces.The histology of the removed specimen also revealed the involvement of the utero-vesical fold,the recto-vaginal septum and a pericolic lymph node,which are all quite uncommon findings.To identify the endometrial cells,we performed immunohistochemical staining for CD10and the estrogen and progesterone receptors. | Andrea Cacciato Insilla Monnalisa Granai Grazia Gallippi Patrizia Giusti Sabina Giusti Simone Guadagni Luca Morelli Daniela Campani | 2014 | World Journal of Gastroenterology2014，20，21： | 4 |
| 13 | Coexpression of CD163 and CD141 identifies human circulating IL-10-producing dendritic cells (DC-10)显示文摘Tolerogenic dendritic cells(DCs)are key players in maintaining immunological homeostasis,dampening immune responses,and promoting tolerance.DC-10,a tolerogenic population of human IL-10-producing DCs characterized by the expression of HLA-G and ILT4,play a pivotal role in promoting tolerance via T regulatory type 1(Tr1)cells.Thus far,the absence of markers that uniquely identify DC-10 has limited in vivo studies.By in vitro gene expression profiling of differentiated human DCs,we identified CD141 and CD163 as surface markers for DC-10.The coexpression of CD141 and CD163 in combination with CD14 and CD16 enables the ex vivo isolation of DC-10 from the peripheral blood.CD14+CD16+CD141+CD163+cells isolated from the peripheral blood of healthy subjects(ex vivo DC-10)produced spontaneously and upon activation of IL-10 and limited levels of IL-12.Moreover,in vitro stimulation of allogeneic naive CD4+T cells with ex vivo DC-10 induced the differentiation of alloantigen-specific CD49b+LAG-3+Tr1 cells.Finally,ex vivo DC-10 and in vitro generated DC-10 exhibited a similar transcriptional profile,which are characterized by an anti-inflammatory and pro-tolerogenic signature.These results provide new insights into the phenotype and molecular signature of DC-10 and highlight the tolerogenic properties of circulating DC-10.These findings open the opportunity to track DC-10 in vivo and to define their role in physiological and pathological settings. | Michela Comi Daniele Avancini Francesca Santoni de Sio Matteo Villa Molly Javier Uyeda Matteo Floris Daniela Tomasoni Alessandro Bulfone Maria Grazia Roncarolo Silvia Gregori | 2020 | Cellular & Molecular Immunology2020，17，1： | 4 |
| 14 | TM6SF2 E167K variant predicts severe liver fibrosis for human immunodeficiency/hepatitis C virus co-infected patients, and severe steatosis only for a non-3 hepatitis C virus genotype显示文摘AIM To evaluate the impact of the Glu167Lys(E167K) transmembrane 6 superfamily member 2(TM6SF2) variant on the biochemical and morphologic expression of liver lesions in human immunodeficiency virus(HIV)/hepatitis C virus(HCV) co-infected patients.METHODS The study comprised 167 consecutive patients with HIV/HCV coinfection and biopsy-proven chronic hepatitis. A pathologist graded liver fibrosis and necroinflammation using the Ishak scoring system, and steatosis using Kleiner's scoring system. Patients were genotyped for TM6SF2 E167K(rs58542926) by real-time Polymerase chain reaction. The 167 patients, 35 therapy-naive and 132 receiving ART, were prevalently males(73.6%), the median age was 40.7 years and the immunological condition good(median CD4+ cells/mm3 = 505.5).RESULTS The 17 patients with the TM6SF2 E167 K variant, compared with the 150 with TM6SF2-E/E, showed higher AST(P = 0.02) and alanine aminotransferase(P = 0.02) and higher fibrosis score(3.1 ± 2.0 vs 2.3 ± 1.5, P = 0.05). In a multivariate analysis, TM6SF2 E167 K was independently associated with severe fibrosis. The same analysis showed that HCV-genotype 3, present in 42.2% of patients was an independent predictor of severe steatosis. The association of TM6SF2 E167 K with severe steatosis, absent for the whole group of 167 patients, was re-evaluated separately for HCVgenotype 3 and non-3 patients: No factor was independently associated with severe steatosis in the HCV-genotype-3 subgroup, whereas an independent association was observed between severe steatosis and TM6SF2 E167 K in non-3 HCV genotypes. No association between the TM6SF2 E167 K variant and severe liver necroinflammation was observed.CONCLUSION In HIV/HCV coinfection the TM6SF2 E167 K variant is an independent predictor of severe fibrosis, but appears to be independently associated with severe steatosis only for patients with a non-3 HCV genotype. | Caterina Sagnelli Marco Merli Caterina Uberti-Foppa Hamid Hasson Anna Grandone Grazia Cirillo Stefania Salpietro Carmine Minichini Mario Starace Emanuela Messina Patrizia Morelli Emanuele Miraglia Del Giudice Adriano Lazzarin Nicola Coppola Evangelista Sagnelli | 2016 | World Journal of Gastroenterology2016，22，38： | 4 |

| 17 | Neutrophil gelatinase-associated lipocalin does not predict acute kidney injury in heart failure显示文摘BACKGROUND Acute cardiorenal syndrome type 1(CRS-1)is defined by a rapid cardiac dysfunction leading to acute kidney injury(AKI).Neutrophil gelatinaseassociated lipocalin(NGAL)is expressed on the surface of human neutrophils and epithelial cells,such as renal tubule cells,and its serum(sNGAL)and urinary have been used to predict AKI in different clinical settings.AIM To characterize CRS-1 in a cohort of patients with acute heart diseases,evaluating the potentiality of sNGAL as an early marker of CRS-1.METHODS We performed a retrospective cohort,multi-centre study.From January 2010 to December 2011,we recruited 202 adult patients admitted to the coronary intensive care unit(CICU)with a diagnosis of acute heart failure or acute coronary syndrome.We monitored the renal function to evaluate CRS-1 development and measured sNGAL levels within 24 h and after 72 h of CICU admission.RESULTS Overall,enrolled patients were hemodynamically stable with a mean arterial pressure of 92(82-107)mmHg,55/202(27.2%)of the patients developed CRS-1,but none of them required dialysis.Neither the NGAL delta value(AUC 0.40,95%CI:0.25-0.55)nor the NGAL peak(AUC 0.45,95%CI:0.36-0.54)or NGAL cutoff(≥140 ng/mL)values were statistically significant between the two groups(CRS-1 vs no-CRS1 patients).The area under the ROC curve for the prediction of CRS-1 was 0.40(95%CI:0.25-0.55)for the delta NGAL value and 0.45(95%CI:0.36-0.54)for the NGAL peak value.Finally,in multivariate analysis,the risk of developing CRS-1 was correlated with age>60 years,urea nitrogen at admission and 24 h-urine output(AUC 0.83,SE=60.5%SP=93%),while sNGAL was not significantly correlated.CONCLUSION In our population,sNGAL does not predict CRS-1,probably as a consequence of the mild renal injury and the low severity of heart disease.So,these data might suggest that patient selection should be taken into account when considering the utility of NGAL measurement as a biomarker of kidney damage. | Fiorenza Ferrari Elisa Scalzotto Pasquale Esposito Sara Samoni Flavio Mistrorigo Lilia Maria Rizo Topete Massimo De Cal Grazia Maria Virzì Valentina Corradi Rossella Torregrossa Roberto Valle Stefania Bianzina Nadia Aspromonte Matteo Floris Alessandro Fontanelli Alessandra Brendolan Claudio Ronco | 2020 | World Journal of Clinical Cases2020，8，9： | 3 |

| 19 | Hepatitis delta virus: From infection to new therapeutic strategies显示文摘The hepatitis delta virus(HDV)is a small RNA virus that encodes a single protein and which requires the hepatitis B virus(HBV)-encoded hepatitis B surface antigen(HBsAg)for its assembly and transmission.HBV/HDV co-infections exist worldwide and show a higher prevalence among selected groups of HBV-infected populations,specifically intravenous drug users,practitioners of high-risk sexual behaviours,and patients with cirrhosis and hepatocellular carcinoma.The chronic form of HDV-related hepatitis is usually severe and rapidly progressive.Patterns of the viral infection itself,including the status of co-infection or super-infection,virus genotypes(both for HBV and HDV),and persistence of the virus’replication,influence the outcome of the accompanying and manifested liver disease.Unfortunately,disease severity is burdened by the lack of an effective cure for either virus type.For decades,the main treatment option has been interferon,administered as mono-therapy or in combination with nucleos(t)ide analogues.While its efficacy has been reported for different doses,durations and courses,only a minority of patients achieve a sustained response,which is the foundation of eventual improvement in related liver fibrosis.The need for an efficient therapeutic alternative remains.Research efforts towards this end have led to new treatment options that target specific steps in the HDV life cycle;the most promising among these are myrcludex B,which inhibits virus entry into hepatocytes,lonafarnib,which inhibits farnesylation of the viral-encoded LHDAg large hepatitis D antigen,and REP-2139,which interferes with HBsAg release and assembly. | Grazia A Niro Arianna Ferro Francesca Cicerchia Isabella Brascugli Marilena Durazzo | 2021 | World Journal of Gastroenterology2021，27，24： | 2 |
| 20 | Emerging actionable targets to treat therapyresistant colorectal cancers显示文摘In the last two decades major improvements have been reached in the early diagnosis of colorectal cancer(CRC)and,besides chemotherapy,an ampler choice of therapeutic approaches is now available,including targeted and immunotherapy.Despite that,CRC remains a“big killer”mainly due to the development of resistance to therapies,especially when the disease is diagnosed after it is already metastatic.At the same time,our knowledge of the mechanisms underlying resistance has been rapidly expanding which allows the development of novel therapeutic options in order to overcome it.As far as resistance to chemotherapy is concerned,several contributors have been identified such as:intake/efflux systems upregulation;alterations in the DNA damage response,due to defect in the DNA checkpoint and repair systems;dysregulation of the expression of apoptotic/anti-apoptotic members of the BCL2 family;overexpression of oncogenic kinases;the presence of cancer stem cells;and the composition of the tumoral microenvironment and that of the gut microbiota.Interestingly,several mechanisms are also involved in the resistance to targeted and/or immunotherapy.For example,overexpression and/or hyperactivation and/or amplification of oncogenic kinases can sustain resistance to targeted therapy whereas the composition of the gut microbiota,as well as that of the tumoral niche,and defects in DNA repair systems are crucial for determining the response to immunotherapy.In this review we will make an overview of the main resistance mechanisms identified so far and of the new therapeutic approaches to overcome it. | Emanuela Grassilli Maria Grazia Cerrito | 2022 | Cancer Drug Resistance2022，5，1： | 2 |
