| 1 | Epidemiology, demographic characteristics and prognostic predictors of ulcerative colitis显示文摘Ulcerative colitis(UC)is a chronic disease characterized by diffuse inflammation of the mucosa of the colon and rectum.The hallmark clinical symptom of UC is bloody diarrhea.The clinical course is marked by exacerbations and remissions,which may occur spontaneously or in response to treatment changes or intercurrent illnesses.UC is most commonly diagnosed in late adolescence or early adulthood,but it can occur at any age.The incidence of UC has increased worldwide over recent decades,especially in developing nations.In contrast,during this period,therapeutic advances have improved the life expectancy of patients,and there has been a decrease in the mortality rate over time.It is important to emphasize that there is considerable variability in the phenotypic presentation of UC.Within this context,certain clinical and demographic characteristics are useful in identifying patients who tend to have more severe evolution of the disease and a poor prognosis.In this group of patients,better clinical surveillance and more intensive therapy may change the natural course of the disease.The aim of this article was to review the epidemiology and demographic characteristics of UC and the factors that may be associated with its clinical prognosis. | Bruno César da Silva Andre Castro Lyra Raquel Rocha Genoile Oliveira Santana | 2014 | World Journal of Gastroenterology2014，20，28： | 48 |
| 2 | Neuroinflammation and oxidative stress act in concert to promote neurodegeneration in the diabetic retina and optic nerve:galectin-3 participation显示文摘Diabetes is a lifelong disease characterized by glucose metabolic imbalance,in which low insulin levels or impaired insulin signaling lead to hyperglycemic state.Within 20 years of diabetes progression,95%of patients will have diabetic retinopathy,the leading cause of visual defects in working-age people worldwide.Although diabetes is considered a microvascular disease,recent studies have shown that neurodegeneration precedes vascular changes within the diabetic visual system,albeit its mechanisms are still under investigation.Neuroinflammation and oxidative stress are intrinsically related phenomena,since macrophage/microglia and astrocytes are the main sources of reactive oxygen species during central nervous system chronic degenerative diseases,and both pathological processes are increased in the visual system during diabetes.The present review will focus on recent findings of the contribution of oxidative stress derived from neuroinflammation in the early neurodegenerative aspects of the diabetic visual system and their relationship with galectin-3. | Henrique Rocha Mendonca Raul Carpi-Santos Karin da Costa Calaza Ana Maria Blanco Martinez | 2020 | Neural Regeneration Research2020，15，4： | 16 |

| 4 | No evidence of HPV DNA in esophageal squamous cell carcinoma in a population of Southern Brazil显示文摘AIM:To investigate the association between human papillomavirus(HPV)and esophageal squamous cell carcinoma(ESCC)in southern Brazil.METHODS:We studied 189 esophageal samples from125 patients from three different groups:(1)102 biopsies from 51 patients with ESCC,with one sample from the tumor and another from normal esophageal mucosa distant from the tumor;(2)50 esophageal biopsies from 37 patients with a previous diagnosis of head and neck squamous cell carcinoma(HNSCC);and(3)37 biopsies from esophageal mucosa with normal appearance from 37 dyspeptic patients,not exposed to smoking or alcohol consumption.Nested-polymerase chain reaction(PCR)with the MY09/11 and GP5/6 L1primers was used to detect HPV L1 in samples fixed in formalin and stored in paraffin blocks.All PCR reactions were performed with a positive control(cervicovaginal samples),with a negative control(Human Genomic DNA)and with a blank reaction containing all reagents except DNA.We took extreme care to prevent DNA contamination in sample collection,processing,and testing.RESULTS:The histological biopsies confirmed the diagnosis of ESCC in 52 samples(51 from ESCC group and 1 from the HNSCC group)and classified as well differentiated(12/52,23.1%),moderately differentiated(27/52,51.9%)or poorly differentiated(7/52,13.5%).One hundred twenty-eight esophageal biopsies were considered normal(51 from the ESCC group,42 from the HNSCC group and 35 from dyspeptic patients).Nine had esophagitis(7 from the HNSCC and 2 from dyspeptic patients).Of a total of 189 samples,only 6 samples had insufficient material for PCR analysis:1 from mucosa distant from the tumor in a patient with ESCC,3from patients with HNSCC and 2 from patients without cancer.In 183 samples(96.8%)GAPDH,G3PDH and/orβ-globin were amplified,thus indicating the adequacy of the DNA in those samples.HPV DNA was negative in all the 183 samples tested:52 with ESCC,9 with esophagitis and 122 with normal esophageal mucosa.CONCLUSION:There was no evidence of HPV infection in different ESCC from southern Brazil. | Luís Carlos Moreira Antunes Joo Carlos Prolla Antonio de Barros Lopes Marta Pires da Rocha Renato Borges Fagundes | 2013 | World Journal of Gastroenterology2013，19，39： | 4 |
| 5 | Oral pharmacological treatment for patent ductus arteriosus in premature neonates with hemodynamic repercussions显示文摘Objective: To evaluate the efficacy of oral indomethacin, ibuprofen, and paracetamol in oral dosage form on patent ductus arteriosus(PDA) in premature neonates with significant clinical and hemodynamic repercussions(CHRs) and to determine the effect of these respective treatments on renal function.Methods: A retrospective study of cases of PDA in premature neonates in the Neonatal Intensive Care Unit was conducted. The treatments consisted of indomethacin[0.2 mg/(kg$d), 3-day cycle], ibuprofen [10 mg/(kg$d) followed by 5 mg/(kg$d), 3-day cycle], and paracetamol(15 mg/kg every 6 h, 5-day cycle). The drugs were administered as an oral solution. The following variables were considered: gestational age,newborn weight at birth, Apgar score, diuresis, serum creatinine and urea levels, and serum electrolyte levels(sodium and potassium).Results: Treatment with indomethacin presented efficacy of 87.5% in closure of the ductus with a mean outcome period of 3.5 d. In premature neonates with CHRs and contraindications for indomethacin, the initial treatment with either ibuprofen or paracetamol failed to close the ductus. However, when this treatment was followed by indomethacin, closure occurred in 66.7% of the neonates, with an outcome period of9.66 d. The initial treatment with one cycle of ibuprofen followed by one or two cycles of paracetamol failed to close the ductus.Conclusions: Oral indomethacin was effective for closure of the PDA in premature neonates with severe CHRs. Oral paracetamol or ibuprofen for PDA closure in premature neonates with severe CHRs and contraindications for indomethacin was ineffective.However, results in clinical improvements of neonates allowed the subsequent use of indomethacin and successful closure of the ductus. A significant reduction of diuresis occurred in neonates who were treated with indomethacin, either as a first-line treatment or after the failure of ibuprofen or paracetamol. | Clarissa de Albuquerque Botura Bruno Ambrósio da Rocha Thiely Balensiefer Franciele Queiroz Ames Ciomar Aparecida Bersani-Amado Roberto Kenji Nakamura Cuman | 2017 | Asian Pacific Journal of Tropical Medicine2017，10，11： | 4 |
| 6 | Chronic myeloid leukemia-from the Philadelphia chromosome to specific target drugs:A literature review显示文摘Chronic myeloid leukemia(CML)is a myeloproliferative neoplasm and was the first neoplastic disease associated with a well-defined genotypic anomaly―the presence of the Philadelphia chromosome.The advances in cytogenetic and molecular assays are of great importance to the diagnosis,prognosis,treatment,and monitoring of CML.The discovery of the breakpoint cluster region(BCR)-Abelson murine leukemia(ABL)1 fusion oncogene has revolutionized the treatment of CML patients by allowing the development of targeted drugs that inhibit the tyrosine kinase activity of the BCR-ABL oncoprotein.Tyrosine kinase inhibitors(known as TKIs)are the standard therapy for CML and greatly increase the survival rates,despite adverse effects and the odds of residual disease after discontinuation of treatment.As therapeutic alternatives,the subsequent TKIs lead to faster and deeper molecular remissions;however,with the emergence of resistance to these drugs,immunotherapy appears as an alternative,which may have a cure potential in these patients.Against this background,this article aims at providing an overview on CML clinical management and a summary on the main targeted drugs available in that context. | Mariana Miranda Sampaio Maria Luísa Cordeiro Santos Hanna Santos Marques Vinícius Lima de Souza Gonçalves Glauber Rocha Lima Araújo Luana Weber Lopes Jonathan Santos Apolonio Camilo Santana Silva Luana Kauany de SáSantos Beatriz Rocha Cuzzuol Quézia Estéfani Silva Guimarães Mariana Novaes Santos Breno Bittencourt de Brito Filipe Antônio França da Silva Márcio Vasconcelos Oliveira Cláudio Lima Souza Fabrício Freire de Melo | 2021 | World Journal of Clinical Oncology2021，12，2： | 3 |
| 7 | Impacts of land use and land cover changes on hydrological processes and sediment yield determined using the SWAT model显示文摘Land use and land cover(LULC)changes strongly affect local hydrology and sediment yields.The current study focused on a basin in the Brazilian Amazon and had the following three objectives:(1)to perform an effective diagnosis of flow and sediment yield,(2)to evaluate the impacts of LULC changes over the last 40 years on the hydro-sedimentological variables,and(3)to investigate the impacts of the possible trends or breaking points in the flow,surface runoff,and sediment yield series.The Soil and Water Assessment Tool(SWAT)model validation showed that the simulated results were consistent with the data measured in the dynamic reproduction of flow seasonality.Furthermore,changes in LULC altered surface runoff,sediment yield,and flow according to the Mann-Kendall and Pettitt non-parametric tests.It was also observed that the sub-basins in which pastureland is predominant are more susceptible to increased surface runoff and sediment yield.According to trend and homogeneity tests,these sub-basins had break points in the time series of these variables.On the other hand,in the sub-basins whose land cover is predominantly forest,the time series is homogeneous and trendless.The current study highlighted the impacts that 40 years of LULC changes in an Amazonian basin had on hydro-sedimentological variables,which,in turn,can play an important role in changing the hydrological cycle,consequently these changes can also impact diverse human activities in the region,such as agribusiness,livestock,energy production,food security,and public water supply.Thus,it is concluded that the SWAT model is a good estimator of hydro-sedimentological processes in Amazonian basins and can be used by decision makers in the management of water and environmental resources. | Edivaldo Afonso de Oliveira Serrao Madson Tavares Silva Thomas Rocha Ferreira Lorena Conceiçao Paiva de Ataide Cleber Assis dos Santos Aline Maria Meiguins de Lima Vicente de Paulo Rodrigues da Silva Francisco de Assis Salviano de Sousa Denis Jose Cardoso Gomes | 2022 | International Journal of Sediment Research2022，37，1： | 3 |
| 8 | Physiological Effect of Kinetin on the Photosynthetic Apparatus and Antioxidant Enzymes Activities During Production of Anthurium显示文摘The results observed in the literature raise the hypothesis according to which cytokinin plays important roles in photosynthetic metabolisms and antioxidant enzymes. Thus, the study aimed to evaluate the effect of foliar application of the isolated cytokinin kinetin at the production cycle, seeking to analyze its effects on enzyme activity and photosynthetic parameters. The plants treated with CK presented reduction of leaf CO_2 assimilation rate(Pn) and stomatal conductance(Gs), while that transpiration rate(Tr) was unaffected. The internal CO_2 concentrations decreased with the increase in cytokinin levels, but were maintained under CK 50 mg·L^(-1). The plants treated with CK 75 mg·L^(-1) was verified higher carboxylation efficiency(Pn/Ci), which was associated to values of CO_2 assimilation and transpiration unaltered. Apparent electron transport rate showed variations in the concentration of 25 mg·L^(-1). Considering the study of enzyme activity, on the other hand, it cannot be stated that kinetin has an effective action in delaying oxidative damage. It presents mixed results, since an efficiency in the application of cytokinin was not observed, presenting induction levels of ascorbate peroxidase activity. Thus, further research is needed to determine more precisely the effects of kinetin on gas exchange and antioxidant enzymes in anthurium plants. | de MOURA Fabiana B. VIEIRA Marcos R. da S.

| 9 | Preservation of platelet function in patients with cirrhosis and thrombocytopenia undergoing esophageal variceal ligation显示文摘Background:Thrombocytopenia is a possible risk factor for bleeding after band ligation of esophageal varices.However,elevated von Willebrand factor(VWF)in cirrhosis improves platelet function and could decrease this risk.Our objective was to assess platelet function in patients with cirrhosis undergoing esophageal variceal ligation(EVL).Methods:The assessment consisted of platelet count,antigen and activity of VWF and VWF-cleaving protease ADAMTS-13 activity,and a platelet adhesion and aggregation test simulating vascular flow in vivo(Impact-RR)prior to EVL.Results:Totally 111 patients were divided into three groups according to platelet count:(1)<50×109/L(n=38,34.2%);(2)50×109/L to 100×109/L(n=47,42.3%);and(3)>100×109/L(n=26,23.4%).No statistically significant difference was found in the aggregate size of platelets[group 1:41.0(31.8–67.3)μm 2;group 2:47.0(33.8–71.3)μm 2;and group 3:47.0(34.0–66.0)μm 2;P=0.60]and no significant correlation was found between aggregate size and platelet count(Spearman r=0.07;P=0.47).Surface coverage was 4.1%(2.8%–6.7%),8.5%(4.0%–10.0%),and 9.0%(7.1%–12.0%)(P<0.001)in groups 1,2 and 3,respectively and correlated with platelet count(Spearman r=0.39;P<0.0001).There was no significant difference between groups in VWF or ADAMTS-13.Post-EVL bleeding occurred in six(5.4%)patients(n=2 in group 1,n=1 in group 2,and n=3 in group 3;P=0.32).Patients with bleeding had higher MELD scores[15.0(11.3–20.3)versus 12.0(10.0–15.0);P=0.025],but no difference was demonstrated for platelet function parameters.Conclusion:Platelet function is preserved even in the presence of thrombocytopenia,including in the patients with post-EVL bleeding. | Evandro de Oliveira Souza Elbio Antonio D’Amico Tania Rubia Flores da Rocha Caroline Marcondes Ferreira Juliana Medeiros Batista Luiz Augusto CarneiroD’Albuquerque Flair Jose Carrilho Alberto Queiroz Farias | 2020 | Hepatobiliary & Pancreatic Diseases International2020，19，6： | 3 |
| 10 | Sex-specific effects of Eugenia punicifolia extract on gastric ulcer healing in rats显示文摘AIM To evaluate the sex-specific effects of a hydroalcoholic extract from Eugenia punicifolia(HEEP) leaves on gastric ulcer healing.METHODS In this rat study involving males, intact(cycling) females, and ovariectomized females, gastric ulcers were induced using acetic acid. A vehicle, lansoprazole, or HEEP was administered for 14 d after ulcer induction. Body weight was monitored throughout the treatment period. At the end of treatment, the rats were euthanized and the following in vivo and in vitro investigations were performed: macroscopic examination of the lesion area and organ weights, biochemical analysis, zymography, and evaluation of protein expression levels. Additionally, the concentration-dependent effect of HEEP was evaluated in terms of subacute toxicity and cytotoxicity.RESULTS Compared to the vehicle, HEEP demonstrated a great healing capacity by substantially reducing the ulcerative lesion area in males(52.44%), intact females(85.22%), and ovariectomized females(65.47%), confirming that HEEP accelerates the healing of acetic acidinduced gastric lesions and suggesting that this effect is modulated by female sex hormones. The antiulcer effect of HEEP was mediated by prostaglandin E2 only in male rats. Overall, the beneficial effect of HEEP was the highest in intact females. Notably, HEEP promoted the expression of vascular endothelial growth factor(intact vs ovariectomized females) and decreased the expression of Caspase-8 and Bcl-2(intact female vs male or ovariectomized female). Additionally, HEEP enhanced fibroblast proliferation and migration into a wounded area in vitro, confirming its healing effect. Finally, no sign of subacute toxicity or cytotoxicity of HEEP was observed.CONCLUSION In gastric ulcers, HEEP-induced healing(modulated by female sex hormones; in males, mediated by prostaglandin) involves extracellular matrix remodeling, with gastric mucosa cell proliferation and migration. | Larissa Lucena Périco Vinícius Peixoto Rodrigues Rie Ohara Gabriela Bueno Vania Vasti Alfieri Nunes Raquel Cássia dos Santos Ana Carolina Lima Camargo Luis Antuio Justulin Joior Sérgio Faloni de Andrade Viviane Miranda Bispo Steimbach Luísa Mota da Silva Lúcia Regina Machado da Rocha Wagner Vilegas Catarina dos Santos Clélia Akiko Hiruma-Lima | 2018 | World Journal of Gastroenterology2018，24，38： | 3 |
| 11 | Acaricidal activity of Derris floribunda essential oil and its main constituent显示文摘Objective: To evaluate the acaricidal activity of the essential oil obtained from roots of Derris floribunda(D. floribunda)(Miq.) Benth, and its main constituent nerolidol against the Mexican mite Tetranychus mexicanus(T. mexicanus)(Mc Gregor).Methods: The essential oil from the roots of D. floribunda collected in the Amazon region(Brazil) was obtained by hydrodistillation. Its chemical composition was determined by GC–MS analysis. The acaricidal activities of this essential oil and nerolidol,were evaluated by recording the number of dead females(mortality) and eggs(fertility).Results: The essential oil showed sesquiterpenes as major volatile components. Nerolidol, the main component, represented 68.5% of the total composition of the essential oil. D. floribunda essential oil and nerolidol showed acaricidal activity, with LC_(50) of9.61 mg/m L air and 9.2 mg/m L air, respectively, over a 72 h period. In addition, both the essential oil and nerolidol significantly reduced the fecundity of T. mexicanus.Conclusions: Due to the economic importance of T. mexicanus and the lack of new pesticides, our data are very promising in the search for efficient and safer acaricidal products. Furthermore, this is the first report about the chemical composition and bioactivity of the essential oil of the Amazon plant species D. floribunda. | Ana Claudia Fernandes Amaral Aline de SRamos Marcia Reis Pena Jose Luiz Pinto Ferreira Jean Michel SMenezes Geraldo JNVasconcelos Neliton Marques da Silva Jefferson Rocha de Andrade Silva | 2017 | Asian Pacific Journal of Tropical Biomedicine2017，7，9： | 2 |
| 12 | Helicobacter pylori infection:How does age influence the inflammatory pattern?显示文摘The inflammatory pattern during Helicobacter pylori(H.pylori)infection is changeable and complex.During childhood,it is possible to observe a predominantly regulatory response,evidenced by high concentrations of key cytokines for the maintenance of Treg responses such as TGF-β1 and IL-10,in addition to high expression of the transcription factor FOXP3.On the other hand,there is a predominance of cytokines associated with the Th1 and Th17 responses among H.pylori-positive adults.In the last few years,the participation of the Th17 response in the gastric inflammation against H.pylori infection has been highlighted due to the high levels of TGF-β1 and IL-17 found in this infectious scenario,and growing evidence has supported a close relationship between this immune response profile and unfavorable outcomes related to the infection.Moreover,this cytokine profile might play a pivotal role in the effectiveness of anti-H.pylori vaccines.It is evident that age is one of the main factors influencing the gastric inflammatory pattern during the infection with H.pylori,and understanding the immune response against the bacterium can assist in the development of alternative prophylactic and therapeutic strategies against the infection as well as in the comprehension of the pathogenesis of the outcomes related to that microorganism. | Glauber Rocha Lima Araújo Hanna Santos Marques Maria Luísa Cordeiro Santos Filipe Antônio França daSilva Breno Bittencourt da Brito Gabriel Lima Correa Santos Fabrício Freire de Melo | 2022 | World Journal of Gastroenterology2022，28，4： | 2 |
| 13 | Interleukin-6-174G/C polymorphism is associated with a decreased risk of type 2 diabetes in patients with chronic hepatitis C virus显示文摘BACKGROUND Chronic hepatitis C(CHC)is associated with type 2 diabetes mellitus.Although the pathogenesis remains to be elucidated,a growing evidence has suggested a role of pro-inflammatory immune response.Increased serum concentrations of Interleukin 6(IL-6)have been associated with insulin resistance,type 2 diabetes mellitus as well as advanced forms of liver disease in chronic hepatitis C infection.AIM To investigate the frequency of IL-6-174G/C(rs1800795)single nucleotide polymorphism(SNP)in CHC patients and in healthy subjects of the same ethnicity.Associations between type 2 diabetes mellitus(dependent variable)and demographic,clinical,nutritional,virological and,IL-6 genotyping data were also investigated in CHC patients.METHODS Two hundred and forty-five patients with CHC and 179 healthy control subjects(blood donors)were prospectively included.Type 2 diabetes mellitus was diagnosed according to the criteria of the American Diabetes Association.Clinical,biochemical,histological and radiological methods were used for the diagnosis of the liver disease.IL-6 polymorphism was evaluated by Taqman SNP genotyping assay.The data were analysed by logistic regression models.RESULTS Type 2 diabetes mellitus,blood hypertension and liver cirrhosis were observed in 20.8%(51/245),40.0%(98/245)and 38.4%(94/245)of the patients,respectively.The frequency of the studied IL-6 SNP did not differ between the CHC patients and controls(P=0.81)and all alleles were in Hardy-Weinberg equilibrium(P=0.38).In the multivariate analysis,type 2 diabetes mellitus was inversely associated with GC and CC genotypes of IL-6-174(OR=0.42;95%CI=0.22-0.78;P=0.006)and positively associated with blood hypertension(OR=5.56;95%CI=2.79-11.09;P<0.001).CONCLUSION This study was the first to show that GC and CC genotypes of IL-6-174 SNP are associated with a decreased risk of type 2 diabetes mellitus in patients chronically infected with hepatitis C virus.The identification of potential inflammatory mediators involved in the crosstalk between hepatitis C virus and the axis pancreas-liver remains important issues that deserve further investigations. | Cliviany Borges da Silva Diego Alves Vieira Luisa Freitas de Melo Anna Luiza Soares Chagas Adriana Dias Gomes César Lúcio Lopes de Faria Jr Rosangela Teixeira Dulciene Maria de Magalh?es Queiroz Gifone Aguiar Rocha Maria Marta Sarquis Soares Juliana Maria Trindade Bezerra Luciana Diniz Silva | 2020 | World Journal of Hepatology2020，12，4： | 2 |
