| 1 | Evaluation of VEGF gene polymorphisms and proliferative diabetic retinopathy in Mexican population显示文摘● AIM: To assess if the included vascular endothelial growth factor(VEGF) polymorphisms rs3025035, rs3025021 and rs2010963 are associated to proliferative retinopathy in a Mexican population with type 2 diabetes mellitus(T2DM).● METHODS: A case-control study was conducted in adult individuals with T2 DM associated to proliferative retinopathy or non-proliferative retinopathy from Oct. 2014 to Jun. 2015 from the Retina Department of the Asociation to Prevent Blindness in Mexico. The selected patients were adults with a diagnosis of T2 DM ≥5y. All subjects had a comprehensive ocular examination and the classification of the retinopathy severity was made considering the Early Treatment Diabetic Retinopathy Study(ETDRS) standardization protocols. Genomic DNA was extracted from whole fresh blood. All samples were genotyped by q PCR for selected VEGF polymorphisms. Hardy-Weinberg equilibrium was calculated by comparing Chi-square values between the expected and the observed values for genotype counts.● RESULTS: In total 142 individuals were enrolled, 71 individuals with T2 DM and associated proliferative retinopathy and 71 individuals with non-proliferative retinopathy. One-sided Fisher's exact test was performed for rs3025021[OR(95% CI)=0.44(0.08-2.2); P=0.25] and rs2010963 [OR(95% CI)=0.63(0.25-1.6); P=0.23]. The minor allelic frequencies obtained were 26% for rs3025021, 10% for rs3025035 and 61% for rs2010963. The pairwise linkage disequilibrium between the three SNP was assessed, and was as follows: rs3025021 vs rs3025035: D'=1.0, r^2=0.1043, P≤0.0001; rs3025021 vs rs2010963: D'=0.442, r^2=0.0446, P=0.149; rs3025035 vs rs2010963: D'=0.505, r^2=0.0214, P=0.142.● CONCLUSION: This is the first analysis involving VEGFA polymorphisms and proliferative diabetic retinopathy in a Mexican population. A major finding of the present study is that none of the polymorphisms studied was significantly associated with proliferative retinopathy. Based on these results, we can infer that different populations have different associations for the same polymorphisms. | Roberto Gonzalez-Salinas Maria C Garcia-Gutierrez Gerardo Garcia-Aguirre Virgilio Morales-Canton Raul Velez-Montoya Vidal R Soberon-Ventura Victoria Gonzalez Rodrigo Lechuga Pablo Garcia-Solis David G Garcia-Gutierrez Marco Vinicio Garcia-Solis Manuel Saenz de Viteri Juan C Solis-S | 2017 | International Journal of Ophthalmology(English edition)2017，10，1： | 12 |
| 2 | Cytokine production in patients with cirrhosis and TLR4 polymorphisms显示文摘AIM:To analyze the cytokine production by peripheral blood cells from cirrhotic patients with and without TLR4 D299G and/or T399I polymorphisms.METHODS:The study included nine patients with cirrhosis and TLR4 D299G and/or T399I polymorphisms,and 10 wild-type patients matched for age,sex and degree of liver failure.TLR4 polymorphisms were determined by sequence-based genotyping.Cytokine production by peripheral blood cells was assessed spontaneously and also after lipopolysaccharide(LPS)and lipoteichoic acid(LTA)stimulation.RESULTS:Patients with TLR4 polymorphisms had a higher incidence of previous hepatic encephalopathy than wild-type patients(78%vs 20%,P=0.02).Spontaneous production of interleukin(IL)-6 and IL-10 was lower in patients with TLR4 polymorphisms than in wild-type patients[IL-6:888.7(172.0-2119.3)pg/m L vs 5540.4(1159.2-26053.9)pg/m L,P<0.001;IL-10:28.7(6.5-177.1)pg/m L vs 117.8(6.5-318.1)pg/m L,P=0.02].However,the production of tumor necrosis factor-α,IL-6 and IL-10 after LPS and LTA stimulation was similar in the two groups.CONCLUSION:TLR4 polymorphisms were associated with a distinctive pattern of cytokine production in cirrhotic patients,suggesting that they play a role in the development of cirrhosis complications. | Juan Camilo Nieto Elisabet Sánchez Eva Román Silvia Vidal Laia Oliva Carlos Guarner-Argente Maria Poca Xavier Torras Cándido Juárez Carlos Guarner German Soriano | 2014 | World Journal of Gastroenterology2014，20，46： | 5 |
| 3 | International NeuroAIDS: prospects of HIV-1 associated neurological com-plications显示文摘Neurological complications associated with HIV-1/AIDS are being recognized with a high frequency that parallels the increased number of AIDS cases. The early infiltration by HIV-1 into the nervous system can cause primary and/or secondary neurological complications. The most common neurocognitive disorder is AIDS Dementia Complex (ADC). In developing countries of Asia the three most opportunistic infections are tuberculosis (TB), cryptococcosis, and Pneumocystis carinii pneumonia. Therefore, it is expected that secondary neurological complications due to TB and cryptococcosis will be the most common cause of morbility and mortality in HIV-1/AIDS cases in China. Research of NeuroAIDS in China is necessary to understand the impact and the biology of HIV-1 in the nervous system. Future studies would include, the molecular epidemiology and the description of opportunistic infections associated to HIV-1; the neuropathological description of primary and secondary HIV-1 complications in different groups; the HIV-1 neurot- ropism and immune response studies for China’s unique HIV-1 strains and recombinant forms derived from the nervous system, including experimental models such as the use of transgenic rats; and the study of potential resistant virus, primarily when the anti-retroviral therapy (ART) has not full access in the brain. | J Roberto TRUJILLO Gilberto JARAMILLO-RANGEL Marta ORTEGA-MARTINEZ Augusto C PENALVA de OLIVEIRA Jose E VIDAL Joseph BRYANT Robert C GALLO | 2005 | Cell Research2005，15，11： | 4 |
| 4 | YKL40 expression in CD14^+ liver cells in acute and chronic injury显示文摘AIM:To demonstrate that CD14 + cells are an important source of the growth factor YKL40 in acute and chronic liver damage.METHODS:Rats were inoculated with one dose of CCl4 to induce acute damage.Liver biopsies were obtained at 0,6,12,24,48 and 72 h.For chronic damage,CCl4 was administered three days per week for 6 or 8 wk.Tissue samples were collected,and cellular populations were isolated by liver digestion and purified by cell sorting.YKL40 mRNA and protein expression were evaluated by realtime polymerase chain reaction and western blot.RESULTS:Acute liver damage induced a rapid increase of YKL40 mRNA beginning at 12 h.Expression peaked at 24 h,with a 26fold increase over basal levels.By 72 h however,YKL40 expression levels had nearly returned to control levels.On the other hand,chronic damage induced a sustained increase in YKL40 expression,with 7and 9fold higher levels at 6 and 8 wk,respectively.The pattern of YKL40 expression in different subpopulations showed that CD14+cells,which include Kupffer cells,are a source of YKL40 after acute damage at 72 h[0.09 relative expression units(REU)]as well as after chronic injury at 6 wk(0.11 REU).Hepatocytes,in turn,accounted for 0.06 and 0.01 REU after 72 h(acute)or 6 wk(chronic),respectively.The rest of the CD14cells(including T lymphocytes,B lymphocytes,natural killer and natural killer T cells) yielded 0.07 and 0.15 REU at 72 h and 6 wk,respectively.YKL40 protein expression in liver was detected at 72 h as well as 6 and 8 wk,with the highest expression relative to controls(11fold;P≤0.05)seen at 6 wk.Macrophages were stimulated by lipopolysaccharide.We demonstrate that under these conditions,these cells showed maximum expression of YKL40 at 12 h,with P<0.05 compared with controls.CONCLUSION:Hepatic CD14 + cells are an YKL40 mRNA and protein source in acute and chronic liver injury,with expression patterns similar to growth factors implicated in inflammationfibrogenesis. | Oscar Pizano-Martínez Irinea Yaez-Sánchez Pilar Alatorre-Carranza Alejandra Miranda-Díaz Pablo C Ortiz-Lazareno Trinidad García-Iglesias Adrian Daneri-Navarro Mónica Vázquez-Del Mercado Mary Fafutis-Morris Vidal Delgado-Rizo | 2011 | World Journal of Gastroenterology2011，17，33： | 3 |
| 5 | Toll-like receptor 4 polymorphisms and bacterial infections in patients with cirrhosis and ascites显示文摘AIM To assess the relationship between the presence of toll-like receptor 4(TLR4) polymorphisms and bacterial infections in cirrhotic patients with ascites. METHODS We prospectively included consecutive patients with cirrhosis and ascites hospitalized during a 6-year period. Patients with human immunodeficiency virus(HIV) infection or any other immunodeficiency, patients with advanced hepatocellular carcinoma(beyond Milan's criteria) or any other condition determining poor short-term prognosis, and patients with a permanent urinary catheter were excluded. The presence of D299 G and/or T399 I TLR4 polymorphisms was determined by sequencing and related to the incidence and probability of bacterial infections, other complications of cirrhosis, hepatocellular carcinoma, and mortality during follow-up. A multivariate analysis to identify predictive variables of mortality in the whole series was performed. RESULTS We included 258 patients: 28(10.8%) were carriers of D299G and/or T399I TLR4 polymorphisms(polymorphism group) and 230 patients were not(wildtype group). The probability of developing any bacterial infection at one-year follow-up was 78% in the polymorphism group and 69% in the wild-type group(P = 0.54). The one-year probability of presenting infections caused by gram-negative bacilli(51% vs 44%, P = 0.68), infections caused by gram-positive cocci(49% vs 40%, P = 0.53), and spontaneous bacterial peritonitis(29% vs 34%, respectively, P = 0.99) did not differ between the two groups. The oneyear probability of transplant-free survival was 55% in the polymorphism group and 66% in the wild-type group(P = 0.15). Multivariate analysis confirmed that age, Child-Pugh score, active alcohol intake, previous hepatic encephalopathy, hepatocellular carcinoma and serum creatinine were associated with a higher risk of death during follow-up. CONCLUSION Genetic polymorphisms D299 G and/or T399 I of TLR4 do not seem to play a relevant role in the predisposition of cirrhotic patients with ascites to bacterial infections. | Edilmar Alvarado-Tapias Carlos Guarner-Argente Elida Oblitas Elisabet Sánchez Silvia Vidal Eva Román Mar Concepción Maria Poca Cristina Gely Oana Pavel Juan Camilo Nieto Cándido Juárez Carlos Guarner Germán Soriano | 2018 | World Journal of Hepatology2018，10，1： | 3 |
