| 1 | Is ARFI elastography reliable for predicting fibrosis severity in chronic HCV hepatitis?显示文摘AIM:To determine whether acoustic radiation force impulse(ARFI) elastography is a reliable method for predicting fibrosis severity in patients with chronic hepatitis C virus(HCV) hepatitis.METHODS:We performed a multicenter study including 274 subjects with HCV chronic hepatitis in which we compared ARFI with liver biopsy(LB).In each patient we performed LB(evaluated according to the Metavir score) and ARFI measurements(using a Siemens Acuson S2000TM ultrasound system:10 valid measurements were performed and median values were calculated and expressed in meters/second(m/s).RESULTS:A direct,strong,correlation(Spearman r = 0.707) was found between ARFI measurements and fibrosis(P < 0.0001).For predicting the presence of fibrosis(F ≥ 1 Metavir),significant fibrosis(F ≥ 2),severe fibrosis(F ≥ 3) and cirrhosis(F = 4),the cutoff values of 1.19,1.21,1.58 and 1.82 m/s were determined,respectively,liver stiffness measurements had 73%,84%,84% and 91% Se respectively;93%,91%,94%,90% Sp,respectively;with AUROCs of 0.880,0.893,0.908 and 0.937,respectively.CONCLUSION:ARFI measurement is a reliable method for predicting the severity of fibrosis in HCV | Ioan Sporea Roxana Sirli Simona Bota Carmen Fierbinteanu-Braticevici Alina Popescu Radu Badea Monica Lupsor Ana Petrisor Mirela Dnil | 2011 | World Journal of Radiology2011，3，7： | 24 |
| 2 | Is it better to use two elastographic methods for liver fibrosis assessment?显示文摘AIM:To find out if by combining 2 ultrasound based elastographic methods:acoustic radiation force impulse(ARFI)elastography and transient elastography(TE),we can improve the prediction of fibrosis in patients with chronic hepatitis C.METHODS:Our study included 197 patients with chronic hepatitis C.In each patient,we performed,in the same session,liver stiffness(LS)measurements by means of TE and ARFI,respectively,and liver biopsy(LB),assessed according to the Metavir score.10 LS measurements were performed both by TE and ARFI;median values were calculated and expressed in kilopascals(kPa)and meters/second(m/s),respectively.Only TE and ARFI measurements with IQR<30%andSR≥60%were considered reliable.RESULTS:On LB 13(6.6%)patients had F0,32(16.2%) had F1,52(26.4%)had F2,47(23.9%)had F3,and 53(26.9%)had F4.A direct,strong correlation was found between TE measurements and fibrosis(r=0.741),between ARFI and fibrosis(r=0.730)and also between TE and ARFI(r=0.675).For predicting significant fibrosis(F≥2),for a cutoff of 6.7 kPa,TE had 77.5% sensitivity(Se)and 86.5%specificity(Sp)[area under the receiver operating characteristic curve(AUROC)0.87] and for a cutoff of 1.2 m/s,ARFI had 76.9%Se and 86.7%Sp(AUROC 0.84).For predicting cirrhosis(F=4),for a cutoff of 12.2 kPa,TE had 96.2%Se and 89.6% Sp(AUROC 0.97)and for a cutoff of 1.8 m/s,ARFI had 90.4%Se and 85.6%Sp(AUROC 0.91).When both elastographic methods were taken into consideration,for predicting significant fibrosis(F≥2),(TE≥6.7 kPa and ARFI≥1.2 m/s)we obtained 60.5%Se,93.3% Sp,96.8%positive predictive value(PPV),41.4%negative predictive value(NPV)and 68%accuracy,while for predicting cirrhosis(TE≥12.2 kPa and ARFI≥1.8 m/s) we obtained 84.9%Se,94.4%Sp,84.9%PPV,94.4% NPV and 91.8%accuracy.CONCLUSION:TE used in combination with ARFI is highly specific for predicting significant fibrosis;therefore when the two methods are concordant,liver biopsy can be avoided. | Ioan Sporea Roxana Sirli Alina Popescu Simona Bota Radu Badea Monica Lupsor Mircea Focsa Mirela Danila | 2011 | World Journal of Gastroenterology2011，17，33： | 11 |
| 3 | Ultrasound-based elastography for the diagnosis of portal hypertension in cirrhotics显示文摘Progressive fibrosis is encountered in almost all chronicliver diseases. Its clinical signs are diagnostic in advanced cirrhosis, but compensated liver cirrhosis is harder to diagnose. Liver biopsy is still considered the reference method for staging the severity of fibrosis, but due to its drawbacks(inter and intra-observer variability, sampling errors, unequal distribution of fibrosis in the liver, and risk of complications and even death), non-invasive methods were developed to assess fibrosis(serologic and elastographic). Elastographic methods can be ultrasound-based or magnetic resonance imaging-based. All ultrasoundbased elastographic methods are valuable for the early diagnosis of cirrhosis, especially transient elastography(TE) and acoustic radiation force impulse(ARFI) elastography, which have similar sensitivities and specificities, although ARFI has better feasibility. TE is a promising method for predicting portal hypertension in cirrhotic patients, but it cannot replace upper digestive endoscopy. The diagnostic accuracy of using ARFI in the liver to predict portal hypertension in cirrhotic patients is debatable, with controversial results in published studies. The accuracy of ARFI elastography may be significantly increased if spleen stiffness is assessed, either alone or in combination with liver stiffness and other parameters. Two-dimensional shearwave elastography, the Elast PQ technique and strain elastography all need to be evaluated as predictors of portal hypertension. | Roxana Sirli Ioan Sporea Alina Popescu Mirela Danila | 2015 | World Journal of Gastroenterology2015，21，41： | 6 |
| 4 | Severe adverse events during antiviral therapy in hepatitis C virus cirrhotic patients: A systematic review显示文摘AIM: To identify severe adverse events (SAEs) leading to treatment discontinuation that occur during antiviral therapy in hepatitis C virus (HCV)-infected cirrhotic patients. METHODS: We identified all the articles published prior to December 2011 in the PubMed, Medline, Lilacs, Scopus, Ovid, EMBASE, Cochrane and Medscape databases that presented these data in cirrhotic patients. These studies evaluated the rate of SAEs leading to discontinuation of standard care treatment: Pegylated interferon (PegIFN) alpha 2a (135-180 μg/wk) or PegIFN alpha 2b (1 or 1.5 μg/kg per week) and ribavirin (800-1200 mg/d). Patients with genotype 1 + 4 underwent treatment for 48 wk, whereas those with genotypes 2 + 3 were treated for 24 wk.RESULTS: We included 17 papers in this review, comprising of 1133 patients. Treatment was discontinued due to SAEs in 14.5% of the patients. The most common SAEs were: severe thrombocytopenia and/or neutropenia (23.2%), psychiatric disorders (15.5%), decompensation of liver cirrhosis (12.1%) and severe anemia (11.2%). The proportion of patients who needed to discontinue their therapy due to SAEs was significantly higher in patients with Child-Pugh class B and Cvs those with Child-Pugh class A: 22%vs 11.4% (P = 0.003). A similar discontinuation rate was found in cirrhotic patients treated with PegIFN alpha 2a and those treated with PegIFN alpha 2b, in combination with ribavirin: 14.2%vs 13.7% (P = 0.96). The overall sustained virological response rate in cirrhotic patients was 37% (95%CI: 33.5-43.1) but was significantly lower in patients with genotype 1 + 4 than in those with genotype 2 + 3: 20.5% (95%CI: 17.9-24.8) vs 56.5% (95%CI: 51.5-63.2), (P < 0.0001). CONCLUSION: Fourteen point five percent of HCV cirrhotic patients treated with PegIFN and ribavirin needed early discontinuation of therapy due to SAEs, the most common cause being hematological disorders. | Simona Bota Ioan Sporea Roxana Sirli Alina Popescu Adriana Maria Neghinǎ Mirela Dǎnilǎ Mihnea Strǎin | 2013 | World Journal of Hepatology2013，5，3： | 6 |
| 5 | Pancreatic tuberculosis in a human immunodeficiency virus positive patient:A case report显示文摘Despite the increased incidence of tuberculosis related to human immunodeficiency virus (HIV) in recent decades, pancreatic tuberculosis has rarely been described. We report a case of pancreatic tuberculosis in a 39-year- old African man who presented with progressive dysphagia, vomiting, weight loss and productive cough, accompanied by localized epigastric pain and one episode of melena. HIV-1 testing was positive and lymphocyte subset profile showed CD4 count of 9/mm3. Abdominal computed tomography (CT) scan with contrast revealed a cystic mass in the body of the pancreas, significant portal and retroperitoneal cystic adenopathy, and multiple cystic lesions in the spleen and liver. CT guided cyst aspiration and node biopsy detected Mycobacterium tuberculosis. The patient responded well on antituberculosis and antiretroviral therapy. Tuberculosis rarely involves the pancreas, probably due to the presence of pancreatic enzymes which interfere with the seeding of Mycobacterium tuberculosis. Pancreatic tuberculosis is considered to be the result of dissemination of the infection from nearby lymphatic nodes. Endoscopic ultrasound or CT guided fine needle aspiration for cytology is the recommended diagnostic technique. Although the prognosis is good with anti-tuberculosis treatment, it could be fatal without correct diagnosis and treatment. The clinician’s high index of suspicion of pancreatic tuberculosis and application of FNAB to obtain pathological evidence are extremely important to a correct diagnosis, especially in young HIV positive patients. | Kiranmayi Tadi Michelle Halpern Mirela Feurdean Joseph McNelis Jeffrey Brensilver | 2008 | World Journal of Gastroenterology2008，14，6： | 4 |
| 6 | Subchronic Oral Cadmium Exposure Exerts both Stimulatory and Suppressive Effects on Pulmonary Inflammation/Immune Reactivity in Rats显示文摘Objective The aim of this study is to investigate the effects of oral cadmium(Cd) ingestion on the pulmonary immune response. Methods Determination of Cd content in lungs and histopathological evaluation of the tissue was performed in rats following 30-day oral Cd administration(5 and 50 mg/L). Antioxidant enzyme defense(superoxide dismutase and catalase), cell infiltration, and production of tumor necrosis factor(TNF) and interferon(IFN)-γ, as well as the activity of myeloperoxidase(MPO), nitric oxide(NO), and various cytokines [interleukin(IL)-1β, IL-6, IL-10, and IL-17] were investigated. Results Cd caused tissue damage and cell infiltration in the lungs, and this damage was more pronounced at higher doses. Cd deposition resulted in lung inflammation characterized by a dose-dependent IL-1β increase in lung homogenates, increased TNF levels at both doses, and IL-6 stimulation at low doses with inhibition observed at higher doses. Cd exerted differential effects on lung leukocytes isolated by enzyme digestion, and these effects were characterized by a lack of change in the production of reactive oxygen and nitrogen species, an inhibition of IL-1β and TNF, and stimulation of MPO and IFN-γ. The higher capacity of Cd-exposed lung cells to respond to the opportunistic pathogen Staphylococcus epidermidis was demonstrated in vitro. Conclusion The potential of ingested Cd to exert both proinflammatory and immunosuppressive effects on pulmonary tissue inflammation and immune reactivity highlights the complex immunomodulatory actions of this metal. | KULAS Jelena NINKOV Marina TUCOVIC Dina POPOV Aleksandrov Aleksandra UKROPINA Mirela CAKIC MILOSEVIC Maja MUTIC Jelena KATARANOVSKI Milena MIKROV Ivana | 2019 | Biomedical and Environmental Sciences2019，32，7： | 4 |

| 13 | Homeomorphic extension of strongly spirallike mappings in C^n显示文摘In this paper we consider a proper subclass nA of the full class of spirallike mappings on the Euclidean unit ball Bn in Cn with respect to a given linear operator A. We use the method of subordination chains to obtain an upper growth result for nA , and we obtain various examples of mappings in the same class of normalized biholomorphic mappings on the unit ball Bn in Cn . We also prove that the class nA is compact, while the full class of spirallike mappings with respect to a linear operator need not be compact in dimension n≥2, even when the operator is diagonal. This is one of the motivations for considering the class nA . Finally we prove that if f is a quasiregular strongly spirallike mapping on Bn such that ||[Df(z)]-1 Af(z)|| is uniformly bounded on Bn , then f extends to a homeomorphism of R2n onto itself. In addition, if A + A* = 2aI n for some a >0, this extension is also quasiconformal on R2n . | CURT Paula KOHR Gabriela KOHR Mirela | 2010 | Science China Mathematics2010，53，1： | 2 |
| 14 | Value of acoustic radiation force impulse elastography for the assessment of ascites syndrome显示文摘AIM:To assess the feasibility of performing acoustic radiation force impulse(ARFI) elastography in patients with ascites and its predictive value for the cirrhotic or non-cirrhotic etiology of ascites.METHODS:Our study included 153 patients with ascites,mean age 58.8 ± 13.1 years.One hundred and fifteen(75.2%) patients had ascites in the context of cirrhosis,29(18.9%) had non-cirrhotic ascites(diagnosed by clinical,ultrasound,endoscopic and/or laparoscopic criteria) and in 9(5.9%) cases we could not establish the etiology of ascites.We performed 10 ARFI measurements and the median value was calculated and expressed in meters/second(m/s).Among the 29 patients with non-cirrhotic ascites were included:20 laparoscopically demonstrated peritoneal carcinomatosis with histological confirmation,7 acute pancreatitis with ascites which later resolved,and one case each of lymphatic ascites and ascites in the context of a liver abscess.In 11 of the 20 patients with peritoneal carcinomatosis,the liver structure was homogenous in the ultrasound examination and in 9 patients the ultrasound exam revealed liver metastases.RESULTS:We could not obtain valid ARFI measurements in 5 patients(3.2%).The mean liver stiffness measurements by means of ARFI were statistically significantly higher in patients with cirrhotic ascites than in those with non-cirrhotic ascites:3.04 ± 0.70 vs 1.45 ± 0.59 m/s(P < 0.001).For a cut-off value of 1.8 m/s for predicting cirrhosis(and ascites in the context of cirrhosis),as obtained in a previous study,ARFI had 98.1% sensitivity,86.2% specificity,96.4% positive predictive value,92.5% negative predictive value and 95.6% accuracy for predicting cirrhotic ascites.For a cut-off value of 1.9 m/s the accuracy was 94.9% and for a 2 m/s cut-off value it was 92.8%.CONCLUSION:ARFI elastography is feasible in most patients with ascites and has a very good predictive value for the cirrhotic or non-cirrhotic etiology of ascites. | Simona Bota Ioan Sporea Roxana Sirli Alina Popescu Mirela Dǎnilǎ Mǎdǎlina Sendroiu | 2011 | World Journal of Radiology2011，3，8： | 2 |

| 20 | Comparative tree-ring anatomy of Fraxinus excelsior with Chalara dieback显示文摘We tested the hypothesis that the biometrical characters of wood elements in ash trees(Fraxinus excelsior L.) become modified in response to the progression of disease caused by Chalara fraxinea. Anatomical analyses were performed on wood samples collected at breast height from the trunks of groups of ash trees which contained healthy, weakened and dead trees. We measured(1) treering width,(2) earlywood vessel diameter,(3) earlywood vessel element length,(4) fibre length,(5) fibre diameter,(6) fibre lumen diameter, and(7) fibre wall thickness. We showed that tree-ring width diminished in all analysed groups during disease progression. However, the greatest suppression of growth was observed in dead trees. In both weakened and dead ash trees, the reduction in tree-ring width was accompanied by diminished vessel diameter in the earlywood of the outermost annual rings. The annual rings of dead trees had shorter fibres having greater lumen diameter and thinner cell walls. Consequently, water conduction in the sapwood of dead ash trees was less efficient owing to reduced vessel diameter, and this seems to be one of the greatest disease-induced morphological modifications. All the anatomical modifications might be due to leaf loss and crown dieback triggered by Chalara fraxinea. | Mirela Tulik Barbaros Yaman Nesibe Kose | 2018 | Journal of Forestry Research2018，29，6： | 1 |
