| 1 | 通过手术导致的重量损失由胃绕过在疾病的肥胖的病人改进非含酒精的脂肪肝疾病显示文摘 AIM:To evaluate the effects of surgical weight loss(Roux-en-Y gastric bypass with a modified Fobi-Capella technique) on non alcoholic fatty liver disease in obese patients.METHODS:A group of 26 morbidly obese patients aged 45 ± 2 years and with a body mass index > 40 kg/m 2 who underwent open surgical weight loss operations had paired liver biopsies,the first at surgery and the second after 16 ± 3 mo of weight loss.Biopsies were evaluated and compared in a blinded fashion.The presence of metabolic syndrome,anthropometric and biochemical variables were also assessed at baseline and at the time of the second biopsy.RESULTS:Percentage of excess weight loss was 72.1% ± 6.6%.There was a reduction in prevalence of metabolic syndrome from 57.7%(15 patients) to 7.7%(2 patients)(P < 0.001).Any significance difference was observed in aspartate aminotransferase or alanine aminotransferase between pre and postsurgery.There were improvements in steatosis(P < 0.001),lobular(P < 0.001) and portal(P < 0.05) inflammation and fibrosis(P < 0.001) at the second biopsy.There were 25(96.1%) patients with non alcoholic steatohepatitis(NASH) in their index biopsy and only four(15.3%) of the repeat biopsies fulfilled the criteria for NASH.The persistence of fibrosis(F > 1) was present in five patients at second biopsy.Steatosis and fibrosis at surgery were predictors of significant fibrosis postsurgery.CONCLUSION:Restrictive mildly malabsorptive surgery provides significant weight loss,resolution of metabolic syndrome and associated abnormal liver histological features in most obese patients. | Víctor Vargas Helena Allende Albert Lecube Maria Teresa Salcedo Juan A Baena-Fustegueras José M Fort Joaquín Rivero Roser Ferrer Roberto Catalán Eva Pardina Santiago Ramón y Cajal Jaime Guardia Julia Peinado-Onsurbe | 2012 | World Journal of Hepatology2012，4，12： | 6 |
| 2 | Association of the level of heteroplasmy of the 15059G>A mutation in the MT-CYB mitochondrial gene with essential hypertension显示文摘AIM: To examine whether the heteroplasmy level for 15059G>A mutation in the mitochondrial genome might be associated with essential hypertension. METHODS: This cross-sectional study involved 196 unrelated participants randomly selected from general population (90 males and 106 females) who underwent a regular medical check-up at the Institute for Ath-erosclerosis Research (Moscow, Russia). One hundred and twenty of them (61%) had essential hypertension, and 76 (39%) were apparently healthy normotensive persons. The level of heteroplasmy for 15059G>A mutation occurring in the coding region of cytochrome b gene (MT-CYB) of mtDNA isolated from the blood leukocytes, was quantified using DNA pyrosequencing method. RESULTS: The 15059G>A heteroplasmy level ranged between 4% and 83%, with a median level of 31%. Between the upper and lower quartiles of 15059G>A heteroplasmy distribution, significant differences were observed for patients' age, systolic blood pressure, and triglyceride levels. 15059G>A heteroplasmy correlated both with age (r = 0.331, P < 0.001) and the presence of hypertension (r = 0.228, P = 0.002). Regression analysis revealed that the age explains 12% variability of 15059G>A heteroplasmy, and hypertension independently explains more 5% variability. The 15059G>A heteroplasmy exceeding 31% was found to be significantly associated with a higher risk of essential hypertension (odds ratio 2.76; P (Fisher) 0.019]. The study participants with high 15059G>A heteroplasmy level were found to have significantly higher age (P < 0.001) and the prevalence of essential hypertension (P = 0.033), as compared to those with low 15059G>A heteroplasmy level. These observations suggested a positive correlation between the level of 15059G>A heteroplasmy and essential hypertension. CONCLUSION: This study provides the evidence of association of mtDNA 15059G>A mutation heteroplasmy with essential hypertension. | Igor A Sobenin Dimitry A Chistiakov Margarita A Sazonova Maria M Ivanova Yuri V Bobryshev Alexander N Orekhov Anton Y Postnov | 2013 | World Journal of Cardiology2013，5，5： | 3 |
