| 2 | Microbiota modification by probiotic supplementation reduces colitis associated colon cancer in mice显示文摘AIM To investigate the effect of probiotic supplementation during the development of an experimental model of colitis associated colon cancer(CAC). METHODS C57 BL/6 mice received an intraperitoneal injection of azoxymethane(10 mg/kg), followed by three cycles of sodium dextran sulphate diluted in water(5% w/v). Probiotic group received daily a mixture of Lactobacillus acidophilus, Lactobacil us rhamnosus and Bifidobacterium bifidum. Microbiota composition was assessed by 16 Sr RNA Illumina Hi Seq sequencing. Colon samples were collected for histological analysis. Tumor cytokines was assessed by Real Time-PCR(Polymerase Chain Reaction); and serum cytokines by Multiplex assay. All tests were two-sided. The level of significance was set at P < 0.05. Graphs were generated and statistical analysis performed using the software Graph Pad Prism 5.0. The project was approved by the institutional review board committee. RESULTS At day 60 after azoxymethane injection, the mean number of tumours in the probiotic group was 40% lower than that in the control group, and the probiotic group exhibited tumours of smaller size(< 2 mm)(P < 0.05). There was no difference in richness and diversity between groups. However, there was a significant difference in beta diversity in the multidimensional scaling analysis. The abundance of the genera Lactobacillus, Bifidobacterium, Allobaculum, Clostridium XI and Clostridium XVⅢ increased in the probiotic group(P < 0.05). The microbial change was accompanied by reduced colitis, demonstrated by a 46% reduction in the colon inflammatory index; reduced expression of the serum chemokines RANTES and Eotaxin; decreased p-IKK and TNF-α and increased IL-10 expression in the colon. CONCLUSION Our results suggest a potential chemopreventive effect of probiotic on CAC. Probiotic supplementation changes microbiota structure and regulates the inflammatory response, reducing colitis and preventing CAC. | Maria Carolina S Mendes Daiane SM Paulino Sandra R Brambilla Juliana A Camargo Gabriela F Persinoti José Barreto C Carvalheira | 2018 | World Journal of Gastroenterology2018，24，18： | 17 |
| 3 | Human bocavirus in children hospitalized for acute respiratory tract infection in Rome显示文摘Background The role of human bocavirus (HBoV) as a respiratory pathogen has not been fulfilled yet.We aimed to describe clinical and serological characteristics of children with HBoV hospitalized for acute respiratory tract infection and to evaluate whether differences occur between HBoV alone and in co-infection.Methods We retrospectively reviewed data from 60 children (median age of 6.2 months,range 0.6-70.9) hospitalized for acute respiratory symptoms,with HBoV detected from a respiratory sample,using a reverse transcriptase-PCR for 14 respiratory viruses (including respiratory syncytial virus (RSV),influenza virus A and B,human coronavirus OC43,229E,NL-63 and HUK1,adenovirus,rhinovirus,parainfluenza virus 1-3,and human metapneumovirus).Results HBoV was detected alone in 29 (48.3%) patients,while in co-infection with other viruses in 31 patients (51.7%),with a peak between December and January.Among the 60 patients,34 were bronchiolitis,19 wheezing,3 pneumonia,2 upper respiratory tract infection,and 2 whooping cough.Seven children (11.6%) required admission to the paediatric intensive care unit (PICU) for respiratory failure.No differences was observed in age,family history for atopy and/or asthma,clinical presentations,chest X-ray,or laboratory findings in children with HBoV alone vs.multiple viral detection.RSV was the most frequently co-detected virus (61.3%).When compared with HBoV detection alone,the co-detection of RSV and HBoV was associated with male sex (P=0.013),younger age (P=0.01),and lower blood neutrophil count (P=0.032).Conclusions HBoV can be detected alone and in co-infection respiratory samples of children with an acute respiratory tract infection.A cause-effect relationship between HBoV and respiratory infection is not clear,so further studies are needed to clarify this point. | Laura Petrarca Raffaella Nenna Antonella Frassanito Alessandra Pierangeli Greta Di Mattia Carolina Scagnolari Fabio Midulla | 2020 | World Journal of Pediatrics2020，16，3： | 17 |

| 5 | Intraoperative cell salvage with autologous transfusion in liver transplantation显示文摘Liver transplant(LT) is the primary treatment for patients with end-stage liver disease. About 25000 LTs are performed annually in the world. The potential for intraoperative bleeding is quite variable. However, massive bleeding is common and requires blood transfusion. Allogeneic blood transfusion has an immunosuppressive effect and an impact on recipient survival, in addition to the risk of transmission of viral infections and transfusion errors, among others.Techniques to prevent excessive bleeding or to use autologous blood have been proposed to minimize the negative effects of allogeneic blood transfusion.Intraoperative reinfusion of autologous blood is possible through previous selfdonation or blood collected during the operation. However, LT does not normally allow autologous transfusion by prior self-donation. Hence, using autologous blood collected intraoperatively is the most feasible option. The use of intraoperative blood salvage autotransfusion(IBSA) minimizes the perioperative use of allogeneic blood, preventing negative transfusion effects without negatively impacting other clinical outcomes. The use of IBSA in patients with cancer is still a matter of debate due to the theoretical risk of reinfusion of tumor cells. However, studies have demonstrated the safety of IBSA in several surgical procedures, including LT for hepatocellular carcinoma. Considering the literature available to date, we can state that IBSA should be routinely used in LT, both in patients with cancer and in patients with benign diseases. | Marcelo A Pinto Marcio F Chedid Leo Sekine Andre P Schmidt Rodrigo P Capra Carolina Prediger Jo?o E Prediger Tomaz JM Grezzana-Filho Cleber RP Kruel | 2019 | World Journal of Gastrointestinal Surgery2019，11，1： | 16 |
| 6 | Role of diet and gut microbiota on colorectal cancer immunomodulation显示文摘Colorectal cancer(CRC) is one of the most commonly diagnosed cancers, and it is characterized by genetic and epigenetic alterations, as well as by inflammatory cell infiltration among malignant and stromal cells. However, this dynamic infiltration can be influenced by the microenvironment to promote tumor proliferation, survival and metastasis or cancer inhibition. In particular, the cancer microenvironment metabolites can regulate the inflammatory cells to induce a chronic inflammatory response that can be a predisposing condition for CRC retention. In addition, some nutritional components might contribute to a chronic inflammatory condition by regulating various immune and inflammatory pathways. Besides that, diet strongly modulates the gut microbiota composition,which has a key role in maintaining gut homeostasis and is associated with the modulation of host inflammatory and immune responses. Therefore, diet has a fundamental role in CRC initiation, progression and prevention. In particular,functional foods such as probiotics, prebiotics and symbiotics can have a potentially positive effect on health beyond basic nutrition and have antiinflammatory effects. In this review, we discuss the influence of diet on gut microbiota composition, focusing on its role on gut inflammation and immunity.Finally, we describe the potential benefits of using probiotics and prebiotics to modulate the host inflammatory response, as well as its application in CRC prevention and treatment. | Carolina Vieira De Almeida Marcela Rodrigues de Camargo Edda Russo Amedeo Amedei | 2019 | World Journal of Gastroenterology2019，25，2： | 16 |
| 7 | DNA and histone methylation in gastric carcinogenesis显示文摘Epigenetic alterations contribute significantly to the development and progression of gastric cancer,one of the leading causes of cancer death worldwide.Epigenetics refers to the number of modifications of the chromatin structure that affect gene expression without altering the primary sequence of DNA,and these changes lead to transcriptional activation or silencing of the gene.Over the years,the study of epigenetic processes has increased,and novel therapeutic approaches that target DNA methylation and histone modifications have emerged.A greater understanding of epigenetics and the therapeutic potential of manipulating these processes is necessary for gastric cancer treatment.Here,we review recent research on the effects of aberrant DNA and histone methylation on the onset and progression of gastric tumors and the development of compounds that target enzymes that regulate the epigenome. | Danielle Queiroz Calcagno Carolina Oliveira Gigek Elizabeth Suchi Chen Rommel Rodriguez Burbano Marília de Arruda Cardoso Smith | 2013 | World Journal of Gastroenterology2013，19，8： | 14 |
| 8 | Non-invasive diagnosis of gastric mucosal atrophy in an asymptomatic population with high prevalence of gastric cancer显示文摘AIM: To validate a non-invasive method to detect gastric mucosal atrophy in a Chilean population with high prevalence of gastric cancer and a poor survival rate. METHODS: We first determined the optimal cut-off level of serum pepsinogen (PG)-1, PG-1/PG-2 ratio and 17-gastrin in 31 voluntary symptomatic patients (mean age: 66.1 years), of them 61% had histologically confirmed gastric atrophy. Then, in a population-based sample of 536 healthy individuals (209 residents in counties with higher relative risk and 327 residents in counties with lower relative risk for gastric cancer), we measured serum anti-H pylori antibodies, PG and 17-gastrin and estimated their risk of gastric cancer. RESULTS: We found that serum PG-1 < 61.5 μg/L, PG-1/PG-2 ratio < 2.2 and 17-gastrin > 13.3 pmol/L had a high specificity (91%-100%) and a fair sensitivity (56%-78%) to detect corpus-predominant atrophy. Based on low serum PG-1 and PG-1/PG-2 ratio together as diagnostic criteria, 12.5% of the asymptomatic subjects had corpus-predominant atrophy (0% of those under 25 years and 20.2% over 65 years old). The frequency of gastric atrophy was similar (12% vs 13%) but H pylori infection rate was slightly higher (77% vs 71%) in the high-risk compared to the low-risk counties. Based on their estimated gastric cancer risk, individuals were classified as: low-risk group (no H pylori infection and no atrophy; n = 115; 21.4%); moderate-risk group(H pylori infection but no atrophy; n = 354, 66.0%); and high-risk group (gastric atrophy, with or without H pylori infection; n = 67, 12.5%). The high-risk group was significantly older (mean age: 61.9 ± 13.3 years), more frequently men and less educated as compared with the low-risk group. CONCLUSION: We propose to concentrate on an upper gastrointestinal endoscopy for detection of early gastric cancer in the high-risk group. This intervention model could improve the poor prognosis of gastric cancer in Chile. | Antonio Rollan Catterina Ferreccio Alessandra Gederlini Carolina Serrano Javiera Torres Paul Harris | 2006 | World Journal of Gastroenterology2006，12，44： | 14 |
| 9 | Differential mercury volatilization by tobacco organs expressing a modi-fied bacterial merA gene显示文摘Mercury pollution is a major environmental problem accompanying industrial activities. Most of the mercury released ends up and retained in the soil as complexes of the toxic ionic mercury (Hg2+), which then can be converted by microbes into the even more toxic methylmercury which tends to bioaccumulate. Mercury detoxification of the soil can also occur by microbes converting the ionic mercury into the least toxic metallic mercury (Hg0) form, which then evaporates. The remediation potentia1 of transgenic plants carrying the MerA gene from E. coLi encoding mercuric ion reductase could be evaluated. A modified version of the gene, optimized for plant codon preferences (merApe9, Rugh et al. 1996), was introduced into tobacco by Agrobacterium-mediated leaf disk transformation. Transgenic seeds were resistant to HgCl2 at 50 μM and some of them (10-20% ) could germinate on media containing as much as 350 μM HgCl2, while the control plants were fully inhibited or died on 50 μM HgCl2. The rate of elemental mercury evolution from Hg2+ (added as HgCl2) was 5-8 times higher for transgenic plants than the control. Mercury volatilization by isolated organs standardized for fresh weight was higher (up to 5 times) in the roots than in shoots or the leaves. The data suggest that it is the root system of the transgenic plants that volatilizes most of the reduced mercury (Hg0). It also suggests that much of the mercury need not enter the vascular system to be transported to the leaves for volatilization. Thansgenic plants with the merApe9 gene may be used to mercury detoxification for environmental improvement in mercury-- contaminated regions more efficiently than it had been predicted based on data on volatilization of whole plants via the upper parts only (Rugh et al. 1996). | HE YU KE, JIAN GE SUN, XIAN ZHONG FENG, MIHALY CZAKU, LASZLO MARTON Depariment of Biological Sciences, University of South Carolina, 700 Sumter Street, Columbia, SC29208, USA National Laboratory of Plant Molecular Genetics, Shanghai Institute of Plant Phy | 2001 | Cell Research2001，11，3： | 14 |

| 11 | Modulation of immunity and inflammatory gene expression in the gut, in inflammatory diseases of the gut and in the liver by probiotics显示文摘The potential for the positive manipulation of the gut microbiome through the introduction of beneficial microbes, as also known as probiotics, is currently an active area of investigation. The FAO/WHO define probiotics as live microorganisms that confer a health benefit to the host when administered in adequate amounts. However, dead bacteria and bacterial molecular components may also exhibit probiotic properties. The results of clinical studies have demonstrated the clinical potential of probiotics in many pathologies, such as allergic diseases, diarrhea, inflammatory bowel disease and viral infection. Several mechanisms have been proposed to explain the beneficial effects of probiotics, most of which involve gene expression regulation in specific tissues, particularly the intestine and liver. Therefore, the modulation of gene expression mediated by probiotics is an important issue that warrants further investigation. In the present paper, we performed a systematic review of the probiotic-mediated modulation of gene expression that is associated with the immune system and inflammation. Between January 1990 to February 2014, Pub Med was searched for articles that were published in English using the Me SH terms 'probiotics ' and ' gene expression ' combined with 'intestines', 'liver', 'enterocytes', 'antigen-presenting cells', 'dendritic cells', 'immune system', and 'inflammation'. Two hundred and five original articles matching these criteria were initially selected, although only those articles that included specific gene expression results(77) were later considered for this review and separated into three major topics: the regulation of immunity and inflammatory gene expression in the gut, in inflammatory diseases of the gut and in the liver. Particular strains of Bifidobacteria, Lactobacilli, Escherichia coli, Propionibacterium, Bacillus and Saccharomyces influence the gene expression of mucins, Toll-like receptors, caspases, nuclear factor-κB, and interleukins and lead mainly to an anti-inflammatory response in cultured enterocytes. In addition, the interaction of commensal bacteria and probiotics with the surface of antigenpresenting cells in vitro results in the downregulation of pro-inflammatory genes that are linked to inflammatory signaling pathways, whereas other anti-inflammatory genes are upregulated. The effects of probiotics have been extensively investigated in animal models ranging from fish to mice, rats and piglets. These bacteria induce a tolerogenic and hyporesponsive immune response in which many genes that are related to the immune system, in particular those genes expressing anti-inflammatory cytokines, are upregulated. By contrast, information related to gene expression in human intestinal cells mediated by the action of probiotics is scarce. There is a need for further clinical studies that evaluate the mechanism of action of probiotics both in healthy humans and in patients with chronic diseases. These types of clinical studies are necessary for addressing the influence of these microorganisms in gene expression for different pathways, particularly thosethat are associated with the immune response,and to better understand the role that probiotics might have in the prevention and treatment of disease. | Julio Plaza-Diaz Carolina Gomez-Llorente Luis Fontana Angel Gil | 2014 | World Journal of Gastroenterology2014，20，42： | 12 |
| 12 | 在有分散的胃的息肉的病人的 colorectal 息肉的风险: 盒子控制研究显示文摘 AIM:To assess the risk of colonic polyps,adenomas and advanced neoplastic lesions(ANL) in patients with sporadic gastric polyps,especially those with fundic gland polyps(FGP).METHODS:Clinical records of patients who had performed an upper and a lower digestive endoscopy between September 2007 and August 2008 were retrospectively analyzed.A case-control study was carried out,calling patients with gastric polyps as 'cases' and patients without gastric polyps as 'controls'.The risk of colonic polyps,adenomas and ANL(villous component ≥ 25%,size ≥ 10 mm,or high grade dysplasia) was assessed [odds ratio(OR) and its corresponding 95%CI].RESULTS:Two hundred and forty seven patients were analyzed:78 with gastric polyps(cases) and 169 without gastric polyps(controls).Among the cases,the majority of gastric polyps were FGP(80%,CI:69-88) and hyperplastic(20%,CI:12-31);25% had colonic polyps(25% hyperplastic and 68% adenomas,from which 45% were ANL).Among the controls,20% had colonic polyps(31% hyperplastic and 63% adenomas,from which 41% were ANL).The patients with sporadic FGP had an OR of 1.56(CI:0.80-3.04) for colonic polyps,an OR of 1.78(CI:0.82-3.84) for colonic adenomas,and an OR of 0.80(CI:0.21-2.98) for ANL.Similar results were found in patients with gastric polyps in general.CONCLUSION:The results of this study did not show more risk of colorectal adenomas or ANL neither in patients with sporadic gastric polyps nor in those with FGP. | Daniel Gustavo Cimmino José Manuel Mella Pablo Luna Raquel González Lisandro Pereyra Carolina Fischer Adriana Mohaidle Beatriz Vizcaino Mario Andres Medrano Adrián Hadad Silvia Pedreira Luis Boerr | 2013 | World Journal of Gastrointestinal Endoscopy2013，5，5： | 12 |
| 13 | Posterior approach (Kraske procedure) for surgical treatment of presacral tumors显示文摘Presacral tumors are rare,but can comprise a great variety of histological types.Congenital tumors are the most common.Once the diagnosis is established,surgical resection is essential because of the potential for malignancy or infection.Previous biopsy is not necessary or may be even harmful.To decide the best surgical approach(abdominal,sacral or combined) an individual and multidisciplinary analysis must be carried out.We report three cases of cystic presacral masses in which a posterior approach(Kraske procedure) enabled complete resection,the only way to decrease local recurrence.All patients had a satisfactory recovery.A brief overview of retrorectal tumors is presented,focusing on classification,clinical presentation,diagnosis and surgical management. | José Manuel Aranda-Narváez Antonio Jesús GonzálezSánchez Custodia Montiel-Casado Belinda Sánchez-Pérez Carolina Jiménez-Mazure Marta Valle-Carbajo Julio Santoyo-Santoyo | 2012 | World Journal of Gastrointestinal Surgery2012，4，5： | 12 |
| 14 | Role of mi RNAs and their potential to be useful as diagnostic and prognostic biomarkers in gastric cancer显示文摘Alterations in epigenetic control of gene expression play an important role in many diseases, including gastric cancer. Many studies have identified a large number of upregulated oncogenic mi RNAs and downregulated tumour-suppressor mi RNAs in this type of cancer. In this review, we provide an overview of the role of mi RNAs, pointing to their potential to be useful as diagnostic and/or prognostic biomarkers in gastric cancer. Moreover, we discuss the influence of polymorphisms and epigenetic modifications on mi RNA activity. | Kelly Cristina da Silva Oliveira Taíssa Maíra Thomaz Araújo Camila Inagaki Albuquerque Gabriela Alcantara Barata Carolina Oliveira Gigek Mariana Ferreira Leal Fernanda Wisnieski Fernando Augusto Rodrigues Mello Junior André Salim Khayat Paulo Pimentel de Assumpcao Rommel Mário Rodriguez Burbano Marília Cardoso Smith Danielle Queiroz Calcagno | 2016 | World Journal of Gastroenterology2016，22，35： | 11 |
| 15 | Management of nonalcoholic fatty liver disease:An evidence-based clinical practice review显示文摘AIM:To build a consensus among Chilean specialists on the appropriate management of patients with nonalcoholic fatty liver disease(NAFLD)in clinical practice.METHODS:NAFLD has now reached epidemic proportions worldwide.The optimal treatment for NAFLD has not been established due to a lack of evidence-based recommendations.An expert panel of members of the Chilean Gastroenterological Society and the Chilean Hepatology Association conducted a structured analysis of the current literature on NAFLD therapy.The quality of the evidence and the level of recommendations supporting each statement were assessed according to the recommendations of the United States Preventive Services Task Force.A modified three-round Delphi technique was used to reach a consensus among the experts.RESULTS:A group of thirteen experts was established.The survey included 17 open-ended questions that were distributed among the experts,who assessed the articles associated with each question.The levels of agreement achieved by the panel were 93.8%in the first round and 100%in the second and third rounds.The final recommendations support the indication of lifestyle changes,including diet and exercise,for all patients with NAFLD.Proven pharmacological therapies include only vitamin E and pioglitazone,which can be used in nondiabetic patients with biopsy-proven nonalcoholic steatohepatitis(the progressive form of NAFLD),although the long-term safety and efficacy of these therapies have not yet been established.CONCLUSION:Current NAFLD management is rapidly evolving,and new pathophysiology-based therapies are expected to be introduced in the near future.All NAFLD patients should be evaluated using a three-focused approach that considers the risks of liver disease,diabetes and cardiovascular events. | Juan P Arab Roberto Candia Rodrigo Zapata Cristián Mu?oz Juan P Arancibia Jaime Poniachik Alejandro Soza Francisco Fuster Javier Brahm Edgar Sanhueza Jorge Contreras M Carolina Cuellar Marco Arrese Arnoldo Riquelme | 2014 | World Journal of Gastroenterology2014，20，34： | 11 |

| 18 | Gut-brain connection: The neuroprotective effects of the anti-diabetic drug liraglutide显示文摘Long-acting glucagon-like peptide-1(GLP-1) analogues marketed for type 2 diabetes(T2D) treatment have been showing positive and protective effects in several different tissues, including pancreas, heart or even brain. This gut secreted hormone plays a potent insulinotropic activity and an important role in maintaining glucose homeostasis. Furthermore, growing evidences suggest the occurrence of several commonalities between T2 D and neurodegenerative diseases, insulin resistance being pointed as a main cause for cognitive decline and increased risk to develop dementia. In this regard, it has also been suggested that stimulation of brain insulin signaling may have a protective role against cognitive deficits. As GLP-1 receptors(GLP-1R) are expressed throughout the central nervous system and GLP-1 may cross the blood-brain-barrier, an emerging hypothesis suggests that they may be promising therapeutic targets against brain dysfunctional insulin signaling-related pathologies. Importantly, GLP-1 actions depend not only on the direct effect mediated by its receptor activation, but also on the gut-brain axis involving an exchange of signals between both tissues via the vagal nerve, thereby regulating numerous physiological functions(e.g., energy homeostasis, glucose-dependent insulin secretion, as well as appetite and weight control). Amongst the incretin/GLP-1 mimetics class of anti-T2 D drugs with an increasingly described neuroprotective potential, the already marketed liraglutide emerged as a GLP-1R agonist highly resistant to dipeptidyl peptidase-4 degradation(thereby having an increased half-life) and whose systemic GLP-1R activity is comparable to that of native GLP-1. Importantly, several preclinical studies showed anti-apoptotic, anti-inflammatory, anti-oxidant and neuroprotective effects of liraglutide against T2 D, stroke and Alzheimer disease(AD), whereas several clinical trials, demonstrated some surprising benefits of liraglutide on weight loss, microglia inhibition, behavior and cognition, and in AD biomarkers. Herein, we discuss the GLP-1 action through the gut-brain axis, the hormone's regulation of some autonomic functions and liraglutide's neuroprotective potential. | Emanuel Monteiro Candeias Inês Carolina Sebastio Susana Maria Cardoso Sónia Catarina Correia Cristina Isabel Carvalho Ana Isabel Plácido Maria Sancha Santos Catarina Resende Oliveira Paula Isabel Moreira Ana Isabel Duarte | 2015 | World Journal of Diabetes2015，6，6： | 9 |
| 19 | New approaches in the treatment of hepatitis C显示文摘About 130-170 million people, is estimated to be infected with the hepatitis C virus(HCV). Chronic HCV infection is one of the leading causes of liverrelated death and in many countries it is the primaryreason for having a liver transplant. The main aim of antiviral treatment is to eradicate the virus. Until a few years ago the only treatment strategy was based on the combination of pegylated interferon and ribavirin(PEG/RBV). However, in genotypes 1 and 4 the rates of viral response did not surpass 50%, reaching up to 80% in the rest. In 2011 approval was given for the first direct acting antiviral agents(DAA), boceprevir and telaprevir, for treatment of genotype 1, in combination with traditional dual therapy. This strategy managed to increase the rates of sustained viral response(SVR) in both naive patients and in retreated patients, but with greater toxicity, interactions and cost, as well as being less safe in patients with advanced disease, in whom this treatment can trigger decompensation or even death. The recent, accelerated incorporation since 2013 of new more effective DAA, with pan-genomic properties and excellent tolerance, besides increasing the rates of SVR(even up to 100%), has also created a new scenario: shorter therapies, less toxicity and regimens free of PEG/RBV. This has enabled their almost generalised applicability in all patients. However, it should be noted that most of the scientific evidence available is based on expert opinion, case-control series, cohort studies and phase 2 and 3 trials, some with a reduced number of patients and select groups. Few data are currently available about the use of these drugs in daily clinical practice, particularly in relation to the appearance of side effects and interactions with other drugs, or their use in special populations or persons with the less common genotypes. This situation suggests the need for the generalised implementation of registries of patients receiving antiviral therapy. The main inconvenience of these new drugs is their high cost. This necessitates selection and prioritization of candidate patients to receive them, via strategies established by the various national organs, in accordance with the recommendations of scientific societies. | rocío gonzález-grande miguel jiménez-pérez carolina gonzález arjona josémostazo torres | 2016 | World Journal of Gastroenterology2016，22，4： | 9 |
| 20 | Impact of antiretroviral therapy on lipid metabolism of human immunodeficiency virus-infected patients: Old and new drugs显示文摘For human immunodeficiency virus(HIV)-infected patients, the 1990s were marked by the introduction of highly active antiretroviral therapy(HAART) representing a new perspective of life for these patients. The use of HAART was shown to effectively suppress the replication of HIV-1 and dramatically reduce mortality and morbidity, which led to a better and longer quality of life for HIV-1-infected patients. Apart from the substantial benefits that result from the use of various HAART regimens, laboratory and clinical experience has shown that HAART can induce severe and considerable adverse effects related to metabolic complications of lipid metabolism, characterized by signs of lipodystrophy, insulin resistance, central adiposity, dyslipidemia, increased risk of cardiovascular disease and even an increased risk of atherosclerosis. New drugs are being studied, new therapeutic strategies are being implemented, and the use of statins, fibrates, and inhibitors of intestinal cholesterol absorption have been effective alternatives. Changes in diet and lifestyle have also shown satisfactory results. | Joel da Cunha Luciana Morganti Ferreira Maselli Ana Carolina Bassi Stern Celso Spada Sérgio Paulo Bydlowski | 2015 | World Journal of Virology2015，4，2： | 9 |
