| 1 | Lymphocyte subsets in alcoholic liver disease显示文摘AIM:To compare lymphocyte subsets between healthy controls and alcoholics with liver disease.METHODS:The patient cohort for this study included individuals who were suspected to have alcoholic liver disease(ALD) and who had undergone liver biopsy(for disease grading and staging,doubts about diagnosis,or concurrent liver disease;n = 56).Normal controls included patients who were admitted for elective cholecystectomy due to non-complicated gallstones(n = 27).Formalin-fixed,paraffin-embedded liver biopsy specimens were sectioned and stained with hematoxylin and eosin and Perls' Prussian blue.The non-alcoholic steatohepatitis score was used to assess markers of ALD.Lymphocyte population subsets were determined by flow cytometry.T lymphocytes were identified(CD3+),and then further subdivided into CD4+ or CD8+ populations.B lymphocytes(CD19+) and natural killer(NK) cell numbers were also measured.In addition to assessing lymphocyte subpopulation differences between ALD patients and controls,we also compared subsets of alcoholic patients without cirrhosis or abstinent cirrhotic patients to normal controls.RESULTS:The patient cohort primarily consisted of older men.Active alcoholism was present in 66.1%.Reported average daily alcohol intake was 164.9 g and the average lifetime cumulative intake was 2211.6 kg.Cirrhosis was present in 39.3% of the patients and 66.1% had significant fibrosis(perisinusoidal and portal/periportal fibrosis,bridging fibrosis,or cirrhosis) in their liver samples.The average Mayo end-stage liver disease score was 7.6.No hereditary hemochromatosis genotypes were found.ALD patients(n = 56) presented with significant lymphopenia(1.5 × 109/L ± 0.5 × 109/L vs 2.1 × 109/L ± 0.5 × 109/L,P < 0.0001),due to a decrease in all lymphocyte subpopulations,except for NK lymphocytes:CD3+(1013.0 ± 406.2/mm3 vs 1523.0 ± 364.6/mm3,P < 0.0001),CD4+(713.5 ± 284.7/mm3 vs 992.4 ± 274.7/mm3,P < 0.0001),CD8+(262.3 ± 140.4/mm3 vs 478.9 ± 164.6/mm3,P < 0.0001),and CD19+(120.6 ± 76.1/mm3 vs 264.6 ± 88.0/mm3,P < 0.0001).CD8+ lymphocytes suffered the greatest reduction,as evidenced by an increase in the CD4+/CD8+ ratio(3.1 ± 1.3 vs 2.3 ± 0.9,P = 0.013).This ratio was associated with the stage of fibrosis on liver biopsy(rs = 0.342,P = 0.01) and with Child-Pugh score(rs = 0.482,P = 0.02).The number of CD8+ lymphocytes also had a positive association with serum ferritin levels(rs = 0.345,P = 0.009).Considering only patients with active alcoholism but not cirrhosis(n = 27),we found similar reductions in total lymphocyte counts(1.8 × 109/L ± 0.3 × 109/L vs 2.1 × 109/L ± 0.5 × 109/L,P = 0.018),and in populations of CD3+(1164.7 ± 376.6/mm3 vs 1523.0 ± 364.6/mm3,P = 0.001),CD4+(759.8 ± 265.0/mm3 vs 992.4 ± 274.7/mm3,P = 0.003),CD8+(330.9 ± 156.3/mm3 vs 478.9 ± 164.6/mm3,P = 0.002),and CD19+(108.8 ± 64.2/mm3 vs 264.6 ± 88.0/mm3,P < 0.0001).In these patients,the CD4+/CD8+ ratio and the number of NK lymphocytes was not significantly different,compared to controls.Comparing patients with liver cirrhosis but without active alcohol consumption(n = 11),we also found significant lymphopenia(1.3 × 109/L ± 0.6 × 109/L vs 2.1 × 109/L ± 0.5 × 109/L,P < 0.0001) and decreases in populations of CD3+(945.5 ± 547.4/mm3 vs 1523.0 ± 364.6/mm3,P = 0.003),CD4+(745.2 ± 389.0/mm3 vs 992.4 ± 274.7/mm3,P = 0.032),CD8+(233.9 ± 120.0/mm3 vs 478.9 ± 164.6/mm3,P < 0.0001),and CD19+(150.8 ± 76.1/mm3 vs 264.6 ± 88.0/mm3,P = 0.001).The NK lymphocyte count was not significantly different,but,in this group,there was a significant increase in the CD4+/CD8+ ratio(3.5 ± 1.3 vs 2.3 ± 0.9,P = 0.01).CONCLUSION:All patient subsets presented with decreased lymphocyte counts,but only patients with advanced fibrosis presented with a significant increase in the CD4+/CD8+ ratio. | Luís Costa Matos Paulo Batista Nuno Monteiro Joo Ribeiro Maria A Cipriano Pedro Henriques Fernando Giro Armando Carvalho | 2013 | World Journal of Hepatology2013，5，2： | 4 |

| 5 | Resveratrol attenuates metabolic,sperm,and testicular changes in adult Wistar rats fed a diet rich in lipids and simple carbohydrates显示文摘High-fat diets affect male reproduction and sexual function.Therefore,we evaluated the effects of prolonged resveratrol administration on the metabolic,sperm,and testicular parameters of rats fed a cafeteria diet.Male Wistar rats were divided at weaning into control(Cv n=20)and cafeteria(CAF,n=16)groups.At 3 months,half of them were given daily supplementations of resveratrol(C-R,n=10;CAF-R,n=8)at a dosage of 30 mg kg-1 body mass for 2 months.Animals were killed at 5 months of age,and blood,spermatozoa,and testes were collected for further analysis.Data were analyzed by one-way ANOVA,and P<0.05 was considered statistically significant.The CAF diet promoted hyperglycemia(P<0.0001),and treatment with resveratrol reversed this condition(P<0.0001).The CAF diet reduced sperm viability and motility,while resveratrol improved these parameters(F<0.05).Regarding testicular morphology,the height of the seminiferous epithelium was reduced in the CAF group compared with that of the C group(P=0.0007).Spermatogenic cell proliferation was also reduced in the CAF group compared with that of the C group.However,the CAF-R showed an increase in cell proliferation rate compared with that of the untreated CAF group(P=0.0024).Although it did not modify body mass,the consumption of a CAF diet promoted hyperglycemia,adverse testicular morphology remodeling,and abnormal sperm,which were attenuated by treatment with resveratrol,thus suggesting a protective effect of this antioxidant on spermatogenesis. | Fabiana A de Oliveira Waldemar S Costa Francisco J B Sampaio Bianca M Gregorio | 2019 | Asian Journal of Andrology2019，21，2： | 2 |
| 6 | Development of hepatorenal syndrome in bile duct ligated rats显示文摘AIM: To evaluate in bile duct ligated rats whether there were progressive alterations of renal function without changes in histopathology. METHODS: Male Wistar rats were submitted to sham-surgery or bile duct ligation (BDL) and divided according to the post-procedure time (2, 4 and 6-wk). To determine renal function parameters, rats wereplaced in metabolic cages and, at the end of the experiment, blood and urine samples were obtained. Histology and hydroxyproline content were analyzed in liver and renal tissue. RESULTS: Rats with 2 wk of BDL increased free water clearance (P = 0.02), reduced urinary osmolality (P = 0.03) and serum creatinine (P = 0.01) in comparison to the sham group. In contrast, rats at 6 wk of BDL showed features of HRS, including signif icant increase in serum creatinine and reductions in creatinine clearance, water excretion and urinary sodium concentration. Rats with 4 wk of BDL exhibited an intermediate stage of renal dysfunction. Progressive hepatic f ibrosis according to post-procedure time was confirmed by histology. The increased levels of liver hydroxyproline contrasted with the absence of structural changes in the kidney, as assessed by histology and unchanged hydroxyproline content in renal tissue. CONCLUSION: Our data show that BDL produced progressive renal dysfunction without structural changes in the kidney, characterizing HRS. The present model will be useful to understand the pathophysiology of HRS. | Regina M Pereira Robson AS dos Santos Eduardo A Oliveira Virgínia HR Leite Filipi LC Dias Alysson S Rezende Lincoln P Costa Lucíola S Barcelos Mauro M Teixeira Ana Cristina Sim■es e Silva | 2008 | World Journal of Gastroenterology2008，14，28： | 2 |
| 7 | Neutrophile-to-lymphocyte,lymphocyte-to-monocyte,and platelet-tolymphocyte ratios as prognostic and response biomarkers for resectable locally advanced gastric cancer显示文摘BACKGROUND Perioperative fluorouracil plus leucovorin,oxaliplatin,and docetaxel(FLOT)improves prognosis in locally advanced gastric cancer(LAGC).Neutrophil-to-lymphocyte(NLR),lymphocyte-tomonocyte(LMR),and platelet-to-lymphocyte(PLR)ratios are prognostic biomarkers but not predictive factors.AIM To assess blood ratios’(NLR,LMR and PLR)potential predictive response to FLOT and survival outcomes in resectable LAGC patients.METHODS This was a multicentric retrospective study investigating the clinical potential of NLR,LMR,and PLR in resectable LAGC patients,treated with at least one preoperative FLOT cycle,from 12 Portuguese hospitals.Means were compared through non-parametric Mann-Whitney tests.Receiver operating characteristic curve analysis defined the cut-off values as:High PLR>141 for progression and>144 for mortality;high LMR>3.56 for T stage regression(TSR).Poisson and Cox regression models the calculated relative risks/hazard ratios,using NLR,pathologic complete response,TSR,and tumor regression grade(TRG)as independent variables,and overall survival(OS)as the dependent variable.RESULTS This study included 295 patients(mean age,63.7 years;59.7% males).NLR was correlated with survival time(r=0.143,P=0.014).PLR was associated with systemic progression during FLOT(P=0.022)and mortality(P=0.013),with high PLR patients having a 2.2-times higher risk of progression[95% confidence interval(CI):0.89-5.26]and 1.5-times higher risk of mortality(95%CI:0.92-2.55).LMR was associated with TSR,and high LMR patients had a 1.4-times higher risk of achieving TSR(95%CI:1.01-1.99).OS benefit was found with TSR(P=0.015)and partial/complete TRG(P<0.001).Patients without TSR and with no evidence of pathological response had 2.1-times(95%CI:1.14-3.96)and 2.8-times(95%CI:1.6-5)higher risk of death.CONCLUSION Higher NLR is correlated with longer survival time.High LMR patients have a higher risk of decreasing T stage,whereas high PLR patients have higher odds of progressing under FLOT and dying.Patients with TSR and a pathological response have better OS and lower risk of dying. | Tiago Cruz Tomás Ines Eiriz Marina Vitorino Rodrigo Vicente Joao Gramaca Alicia Guadalupe Oliveira Paulo Luz Mafalda Baleiras Ana Sofia Spencer Luísa Leal Costa Patrícia Liu Joana Mendonca Magno Dinis Teresa Padrao Marisol Correia Goncalo Atalaia Michelle Silva Teresa Fiúza | 2022 | World Journal of Gastrointestinal Oncology2022，14，7： | 2 |
