| 1 | Contribution of the IL-17/IL-23 axis to the pathogenesis of inflammatory bowel disease显示文摘Inflammatory bowel diseases(IBDs) are chronic disorders of modern society, requiring management strategies aimed at prolonging an active life and establishing the exact etiology and pathogenesis.These idiopathic diseases have environmental, genetic,immunologic, inflammatory, and oxidative stress components. On the one hand, recent advances have shown that abnormal immune reactions against the microorganisms of the intestinal flora are responsible for the inflammation in genetically susceptible individuals. On the other hand, in addition to T helper cell-type(Th) 1 and Th2 immune responses,other subsets of T cells, namely regulatory T cells and Th17 maintained by IL-23 are likely to develop IBD. IL-23 acts on innate immune system members and also facilitates the expansion and maintenance of Th17 cells. The IL-17/IL-23 axis is relevant in IBD pathogenesis both in human and experimental studies. Novel biomarkers of IBD could be calprotectin,microRNAs, and serum proinflammatory cytokines.An efficient strategy for IBD therapy is represented by the combination of IL-17 A and IL-17 F in acute IL-17 A knockout TNBS-induced colitis, and also definite decrease of the inflammatory process in IL-17 F knockout, DSS-induced colitis have been observed.Studying the correlation between innate and adaptive immune systems, we hope to obtain a focused reviewin order to facilitate future approaches aimed at elucidating the immunological mechanisms that control gut inflammation. | Cristina-Sorina Cǎanǎ Ioana Berindan Neagoe Vasile Cozma Cristian Magdas Flaviu Tǎbǎan Dan Lucian Dumitrasu | 2015 | World Journal of Gastroenterology2015，21，19： | 37 |
| 2 | 为弥漫的甲状腺腺病理的评估的 ARFI elastography : 初步的结果显示文摘 AIM:To assess whether acoustic radiation force impulse(ARFI)elastography can differentiate normal from pathological thyroid parenchyma.METHODS:We evaluated 136 subjects(mean age 45.8±15.6 years,106 women and 30 men):44(32.3%) without thyroid pathology,48(35.3%)with BasedowGraves’disease(GD),37(27.2%)with chronic autoimmune thyroiditis(CAT;diagnosed by specific tests),4(2.9%)with diffuse thyroid goiter and 3(2.2%)cases with thyroid pathology induced by amiodarone.In all patients,10 elastographic measurements were made in the right thyroid lobe and 10 in the left thyroid lobe,using a 1-4.5 MHZ convex probe and a 4-9 MHz linear probe,respectively.Median values were calculated for thyroid stiffness and expressed in meters/second(m/s).RESULTS:Thyroid stiffness(TS)assessed by means of ARFI in healthy subjects(2±0.40 m/s)was significantly lower than in GD(2.67±0.53 m/s)(P<0.0001) and CAT patients(2.43±0.58 m/s)(P=0.0002),but the differences were not significant between GDvs CAT patients(P=0.053).The optimal cut-off value for the prediction of diffuse thyroid pathology was 2.36 m/s.For this cut-off value,TS had 62.5%sensitivity,79.5% specificity,87.6%predictive positive value,55.5% negative predictive value and 72.7%accuracy for the presence of diffuse thyroid gland pathology(AUROC=0.804).There were no significant differences between the TS values obtained with linear vs convex probes and when 5 vs 10 measurements were taken in each lobe(median values).CONCLUSION:ARFI seems to be a useful method for the assessment of diffuse thyroid gland pathology. | Ioan Sporea Roxana Sirli Simona Bota Mihaela Vlad Alina Popescu Ioana Zosin | 2012 | World Journal of Radiology2012，4，4： | 25 |
| 3 | Autophagy in colorectal cancer:An important switch from physiology to pathology显示文摘Colorectal cancer(CRC) remains a leading cause of cancer death in both men and women worldwide.Among the factors and mechanisms that are involved in the multifactorial etiology of CRC,autophagy is an important transformational switch that occurs when a cell shifts from normal to malignant.In recent years,multiple hypotheses have been considered regarding the autophagy mechanisms that are involved in cancer.The currently accepted hypothesis is that autophagy has dual and contradictory roles in carcinogenesis,but the precise mechanisms leading to autophagy in cancer are not yet fully defined and seem to be context dependent.Autophagy is a surveillance mechanism used by normal cells that protects them from the transformation to malignancy by removing damaged organelles and aggregated proteins and by reducing reactive oxygen species,mitochondrial abnormalities and DNA damage.However,autophagy also supports tumor formation by promoting access to nutrients that are critical to the metabolism and growth of tumor cells and by inhibiting cellular death and increasing drug resistance.Autophagy studies in CRC have focused on several molecules,mainly microtubule-associated protein 1 light chain 3,beclin 1,and autophagy related 5,with conflicting results.Beneficial effects were observed for some agents that modulate autophagy in CRC either alone or,more often,in combination with other agents.More extensive studies are needed in the future to clarify the roles of autophagy-related genes and modulators in colorectal carcinogenesis,and to develop potential beneficial agents for the prognosis and treatment of CRC. | Florin Burada Elena Raluca Nicoli Marius Eugen Ciurea Daniel Constantin Uscatu Mihai Ioana Dan Ionut Gheonea | 2015 | World Journal of Gastrointestinal Oncology2015，7，11： | 15 |
| 4 | Safety of endoscopic retrograde cholangiopancreatography in pregnancy: Fluoroscopy time and fetal exposure, does it matter?显示文摘AIM: To estimate the fetal radiation exposure using thermoluminescent dosimeters (TLD's) in pregnant patients undergoing endoscopic retrograde cholangiopancreatography (ERCP) and assess its relevance. METHODS: Data on thirty-five therapeutic ERCPs conducted in pregnant patients from 2001 to 2009 were retrieved from a prospective database. Techniques to minimize fluoroscopy time were implemented and the fluoroscopy times captured. TLD's were placed on the mother to estimate the fetal radiation exposure and the results were compared to the maximum allowed dose of radiation to the fetus [0.005 gray (Gy)]. Obstetrics consultations were obtained and the fetus was monitored before and after the ERCP. Fluoroscopy wasperformed at 75 kVp. ERCP was performed with the patients supine by dedicated biliary endoscopists performing more than 500 cases a year. RESULTS: A total of 35 pregnant patients underwent ERCP and biliary sphincterotomy (14 in first trimester, 11 in second trimester, and 10 in third trimester). Mean maternal age was 25 years (range 16-37 years) and mean gestational age was 18.9 wk (range 4-35 wk). Mean fluoroscopy time was 0.15 min (range 0-1 min). For 23 women, the estimated fetal radiation exposure was almost negligible (< 0.0001 Gy) while for 8 women, it was within the 0.0001-0.0002 Gy range. Three women had an estimated fetal radiation exposure between 0.0002 and 0.0005 Gy and 1 woman had an estimated fetal radiation exposure greater than 0.0005 Gy. Complications included 2 post-sphincterotomy bleeds, 2 post-ERCP pancreatitis, and 1 fatal acute respiratory distress syndrome. One patient developed cholecystitis 2 d after ERCP. CONCLUSION: ERCP with modified techniques is safe during pregnancy, and estimating the fetal radiation exposure from the fluoroscopy time or measuring it via TLD's is unnecessary. | Ioana Smith Monica Gaidhane Allen Goode Michel Kahaleh | 2013 | World Journal of Gastrointestinal Endoscopy2013，5，4： | 12 |
| 5 | Staging of portal hypertension and portosystemic shunts using dynamic nuclear medicine investigations显示文摘AIM: To explore portal hypertension and portosys-temic shunts and to stage chronic liver disease (CLD) based on the pathophysiology of portal hemodynam-ics. METHODS: Per-rectal portal scintigraphy (PRPS) was performed on 312 patients with CLD and liver angio-scintigraphy (LAS) on 231 of them. The control group included 25 healthy subjects. We developed a new model of PRPS interpretation by introducing two new parameters,the liver transit time (LTT) and the circu-lation time between right heart and liver (RHLT). LTT for each lobe was used to evaluate the early portal hypertension. RHLT is useful in cirrhosis to detect liver areas missing portal in? ow. We calculated the classical per-rectal portal shunt index (PRSI) at PRPS and the hepatic perfusion index (HPI) at LAS. RESULTS: The normal LTT value was 24 ± 1 s. Abnor-mal LTT had PPV = 100% for CLD. Twenty-seven non-cirrhotic patients had LTT increased up to 35 s (median 27 s). RHLT (42 ± 1 s) was not related to liver disease. Cirrhosis could be excluded in all patients with PRSI < 5% (P < 0.01). PRSI > 30% had PPV = 100% for cirrhosis. Based on PRPS and LAS we propose the clas-sifi cation of CLD in 5 hemodynamic stages. Stage 0 is normal (LTT = 24 s,PRSI < 5%). In stage 1,LTT is increased,while PRSI remains normal. In stage 2,LTT is decreased between 16 s and 23 s,whereas PRSI is increased between 5% and 10%. In stage 3,PRSI is increased to 10%-30%,and LTT becomes undetect-able by PRPS due to the portosystemic shunts. Stage 4 includes the patients with PRSI > 30%. RHLT and HPI were used to subtype stage 4. In our study stage 0 had NPV = 100% for CLD,stage 1 had PPV = 100% for non-cirrhotic CLD,stages 2 and 3 represented the transition from chronic hepatitis to cirrhosis,stage 4 had PPV = 100% for cirrhosis. CONCLUSION: LTT allows the detection of early por-tal hypertension and of opening of transhepatic shunts. PRSI is useful in CLD with extrahepatic portosystemic shunts. Our hemodynamic model stages the evolution of portal hypertension and portosystemic shunts. It may be of use in the selection of patients for interferon therapy. | Mircea Dragoteanu Ioan A Balea Liliana A Dina Cecilia D Piglesan Ioana Grigorescu Stefan Tamas Sabin O Cotul | 2008 | World Journal of Gastroenterology2008，14，24： | 7 |
| 6 | Arrhythmia risk in liver cirrhosis显示文摘Interactions between the functioning of the heart and the liver have been described, with heart diseases affecting the liver, liver diseases affecting the heart, and conditions that simultaneously affect both. The heart is one of the most adversely affected organs in patients with liver cirrhosis. For example, arrhythmias and electrocardiographic changes are observed in patients with liver cirrhosis. The risk for arrhythmia is influenced by factors such as cirrhotic cardiomyopathy, cardiac ion channel remodeling, electrolyte imbalances,impaired autonomic function, hepatorenal syndrome, metabolic abnormalities, advanced age, inflammatory syndrome, stressful events, impaired drug metabolism and comorbidities. Close monitoring of cirrhotic patients is needed for arrhythmias, particularly when QT intervalprolonging drugs are given, or if electrolyte imbalances or hepatorenal syndrome appear. Arrhythmia risk may persist after liver transplantation due to possible QT interval prolongation, persistence of the parasympathetic impairment, post-transplant reperfusion and chronic immunosuppression, as well as consideration of the fact that the transplant itself is a stressful event for the cardiovascular system. The aims of the present article were to provide a review of the most important data regarding the epidemiology, pathophysiology, and biomarkers of arrhythmia risk in patients with liver cirrhosis, to elucidate the association with long-term outcome, and to propose future research directions. | Ioana Mozos | 2015 | World Journal of Hepatology2015，7，4： | 6 |
| 7 | High levels of homocysteine downregulate apolipoprotein E expression via nuclear factor kappa B显示文摘AIM: To investigate the effect of high homocysteine(Hcy) levels on apolipoprotein E(apoE) expression and the signaling pathways involved in this gene regulation.METHODS: Reverse transcriptase polymerase chain reaction(RT-PCR) and Western blot were used to assess apo E expression in cells treated with various concentrations(50-500 μmol/L) of Hcy. Calcium phosphatetransient transfections were performed in HEK-293 and RAW 264.7 cells to evaluate the effect of Hcy on apoE regulatory elements [promoter and distal multienhancer 2(ME2)]. To this aim, plasmids containing the proximal apoE promoter [(-500/+73)apoE construct] alone or in the presence of ME2 [ME2/(-500/+73)apoE construct] to drive the expression of the reporter luciferase gene were used. Co-transfection experiments were carried out to investigate the downstream effectors of Hcymediated regulation of apoE promoter by using specific inhibitors or a dominant negative form of IKβ. In other co-transfections, the luciferase reporter was under the control of synthetic promoters containing multiple specific binding sites for nuclear factor kappa B(NF-κB), activator protein-1(AP-1) or nuclear factor of activated T cells(NFAT). Chromatin immunoprecipitation(ChI P)assay was accomplished to detect the binding of NF-κB p65 subunit to the apoE promoter in HEK-293 treated with 500 μmol/L Hcy. As control, cells were incubated with similar concentration of cysteine. NF-κB p65 proteins bound to DNA were immunoprecipitated with anti-p65 antibodies and DNA was identified by PCR using primers amplifying the region-100/+4 of the apoE gene. RESULTS: RT-PCR revealed that high levels of Hcy(250-750 μmol/L) induced a 2-3 fold decrease in apoE m RNA levels in HEK-293 cells, while apo E gene expression was not significantly affected by treatment with lower concentrations of Hcy(100 μmol/L). Immunoblotting data provided additional evidence for the negative role of Hcy in apoE expression. Hcy decreased apoE promoter activity, in the presence or absence of ME2, in a dose dependent manner, in both RAW 264.7 and HEK-293 cells, as revealed by transient transfection experiments. The downstream effectors of the signaling pathways of Hcy were also investigated. The inhibitory effect of Hcy on the apo E promoter activity was counteracted by MAPK/ERK kinase 1/2(MEK1/2) inhibitor U0126, suggesting that MEK1/2 is involved in the downregulation of apoE promoter activity by Hcy. Our data demonstrated that Hcy-induced inhibition of apoE took place through activation of NF-κB. Moreover, we demonstrated that Hcy activated a synthetic promoter containing three NF-κB binding sites, but did not affect promoters containing AP-1 or NFAT binding sites. ChI P experiments revealed that NF-κB p65 subunit is recruited to the apoE promoter following Hcy treatment of cells.CONCLUSION: Hcy-induced stress negatively modulates apoE expression via MEK1/2 and NF-κB activation. The decreased apo E expression in peripheral tissues may aggravate atherosclerosis, neurodegenerative diseases and renal dysfunctions. | Violeta G Trusca Adina D Mihai Elena V Fuior Ioana M Fenyo Anca V Gafencu | 2016 | World Journal of Biological Chemistry2016，7，1： | 6 |
| 8 | COX-2 as a potential biomarker and therapeutic target in melanoma显示文摘With a constantly increasing incidence,cutaneous melanoma has raised the need for a better understanding of its complex microenvironment that may further guide therapeutic options.Melanoma is a model tumor in immuno-oncology.Inflammation represents an important hallmark of cancer capable of inducing and sustaining tumor development.The inflammatory process also orchestrates the adaptative immunosuppression of tumor cells that helps them to evade immune destruction.Besides its role in proliferation,angiogenesis,and apoptosis,cyclooxygenase-2(COX-2)is a well-known promoter of immune suppression in melanoma.COX-2 inhibitors are closely involved in this condition.This review attempts to answer two controversial questions:is COX-2 a valuable prognostic factor?Among all COX-2 inhibitors,is celecoxib a suitable adjuvant in melanoma therapy? | Diana Valentina Tudor Ioana Baldea Mihai Lupu Teodor Kacso Eniko Kutasi Andreea Hopartean Roland Stretea Adriana Gabriela Filip | 2020 | Cancer Biology & Medicine2020，17，1： | 6 |
| 9 | Diagnostic challenges in non-cirrhotic portal hypertension-porto sinusoidal vascular disease显示文摘Non-cirrhotic portal hypertension consists of a group of diseases characterized by signs and complications of portal hypertension,which differ from cirrhosis through histological alterations,hemodynamic characterization and,clinical outcome.Because of the similarities in clinical presentation and imaging signs,frequently these patients,and particularly those with porto-sinusoidal vascular disease(PSVD),are misdiagnosed as having liver cirrhosis and thus raising difficulties in their diagnosis.The most challenging differentiation to be considered is between PSVD and cirrhosis and,although not pathognomonic,liver biopsy is still the standard of diagnosis.Although they still require extended validation before being broadly used,new non-invasive methods for the diagnosis of porto-sinusoidal vascular disease,like transient elastography,contrast-enhanced ultrasound or metabolomic profiling,have shown promising results.Another issue is the differentiation between PSVD and chronic extrahepatic portal vein obstruction,especially now when it is known that 40%of patients suffering from PSVD develop portal vein thrombosis.In this particular case,once the portal vein thrombosis occurred,the diagnosis of PSVD is impossible according to the current guidelines.Moreover,so far,the differentiation between PSVD and sinusoidal obstruction syndrome has not been clear so far in particular circumstances.In this review we highlighted the diagnostic challenges regarding the PSVD,as well as the current techniques used in the evaluation of these patients. | Oana Nicoara-Farcau Ioana Rusu Horia Stefanescu Marcel Tanțau Radu Ion Badea Bogdan Procopet | 2020 | World Journal of Gastroenterology2020，26，22： | 4 |
| 10 | Neurological complications of hematopoietic cell transplantation in children and adults显示文摘Hematopoietic cell transplantation(HCT) is widely performed for neoplastic and non-neoplastic diseases. HCT involves intravenous infusion of hematopoietic progenitor cells from human leukocyte antigen(HLA)-matched donor(allogeneic) or from the patient(autologous). Before HCT, the patient is prepared with high dose chemotherapy and/or radiotherapy to destroy residual malignant cells and to reduce immunologic resistance. After HCT, chemotherapy is used to prevent graft rejection and graft versus host disease(Gv HD). Neurological complications are related to the type of HCT, underlying disease, toxicity of the conditioning regimens, immunosuppression caused by conditioning regimens, vascular complications generated by thrombocytopenia and/or coagulopathy, Gv HD and inappropriate immune response. In this review, neurological complications are presented according to time of onset after HCT:(1) early complications(in the first month)-related to harvesting of stem cells, during conditioning(drug toxicity, posterior reversible encephalopathy syndrome), related to pancytopenia,(2) intermediate phase complications(second to sixth month)-central nervous system infections caused by prolonged neutropenia and progressive multifocal leukoencephalopathy due to JC virus,(3) late phase complications(after sixth month)-neurological complications of Gv HD, second neoplasms and relapses of the original disease. | Adriana Octaviana Dulamea Ioana Gabriela Lupescu | 2018 | Neural Regeneration Research2018，13，6： | 3 |

| 12 | Extrahepatic cholangiocarcinoma:Current status of endoscopic approach and additional therapies显示文摘The prognosis of patients with advanced or unresectable extrahepatic cholangiocarcinoma is poor.More than 50%of patients with jaundice are inoperable at the time of first diagnosis.Endoscopic treatment in patients with obstructive jaundice ensures bile duct drainage in preoperative or palliative settings.Relief of symptoms(pain,pruritus,jaundice)and improvement in quality of life are the aims of palliative therapy.Stent implantation by endoscopic retrograde cholangiopancreatography is generally preferred for long-term palliation.There is a vast variety of plastic and metal stents,covered or uncovered.The stent choice depends on the expected length of survival,quality of life,costs and physician expertise.This review will provide the framework for the endoscopic minimally invasive therapy in extrahepatic cholangiocarcinoma.Moreover,additional therapies,such as brachytherapy,photodynamic therapy,radiofrequency ablation,chemotherapy,molecular-targeted therapy and/or immunotherapy by the endoscopic approach,are the nonsurgical methods associated with survival improvement rate and/or local symptom palliation. | Alina Ioana Tantau Alina Mandrutiu Anamaria Pop Roxana Delia Zaharie Dana Crisan Carmen Monica Preda Marcel Tantau Voicu Mercea | 2021 | World Journal of Hepatology2021，13，2： | 3 |
| 13 | Spontaneous and antiviral-induced cutaneous lesions in chronic hepatitis B virus infection显示文摘AIM:To describe spontaneous,or interferon(IFN)-or immunization-induced skin lesions in hepatitis B virus(HBV)infection.METHODS:A comprehensive literature search of all the papers presenting case reports of dermatological lesions in patients with chronic HBV infection was carried out.We included only patients with histologically proven skin lesions that appeared in the normal course of hepatitis B infection,or after immunization for hepatitis B or antiviral treatment.RESULTS:We found 44 papers on this topic,reporting 151 cases.About 2%of patients with hepatitis B infection,mainly men,presented with skin lesions.Among patients with chronic hepatitis B,vasculitis and essential mixed cryoglobulinemia seemed to be the most frequent skin lesion(53.3%),followed by papular changes,rashes and Gianotti-Crosti syndrome,skin carcinoma and Henoch-Sch?nlein purpura were rare.IFN treatment seemed to be effective against HBV-associated and immunoglobulin-complex-mediated disease(vasculitis).Two cutaneous lesions(lichen planus andgranuloma annulare)were described after hepatitis B vaccination.Systemic lupus and lupus-like lesions were the most frequently encountered lesions after antiviral treatment.Immunosuppressive and steroid therapy ameliorates lichen planus lesions in 50%of cases.CONCLUSION:Vasculitis was the most frequent spontaneous skin lesion found in chronic hepatitis B.Lichen planus was most frequent after immunization and lupus/lupus-like lesions after IFN. | Ioana Grigorescu Dan Lucian Dumitrascu | 2014 | World Journal of Gastroenterology2014，20，42： | 3 |
| 14 | Fluoropyrimidine-induced cardiotoxicity显示文摘Cardio-oncology is a discipline based on early screening,monitoring,and treating chemotherapy-induced cardiotoxicity.There are many chemotherapeutics known for their cardiac toxic effects,including fluoropyrimidines.Fluoropyrimidine represents the cornerstone of many types of cancer and each year almost two million cancer patients undergo this treatment.Fluoropyrimidine-induced cardiotoxicity can be manifested in several forms,from angina pectoris to sudden death.This paper is a review of how the cardiotoxicity of fluoropyrimidines is presented,the mechanisms of its occurrence,its diagnosis,and management. | Andrada Larisa Deac Claudia Cristina Burz Ioana Corina Bocsan Anca Dana Buzoianu | 2020 | World Journal of Clinical Oncology2020，11，12： | 2 |
