- Abstract
The expression levels of micro ribonucleic acid-183 (miR-183) and miR-141 in the lesion tissues of infected abdominal aortic aneurysm (IAAA) and their relationship with prognosis were investigated. Thirty-six patients with IAAA admitted and who underwent vascular surgery in People's Hospital of Shenzhen from June 2003 to June 2013 were selected. Reverse transcription polymerase chain reaction (RT-PCR) was utilized to detect the expression levels of miR-183 and miR-141 in lesion tissues and adjacent tissues 1 cm away from the aneurysm in 36 patients with IAAA. The relationship between the expression levels of miR-183 and miR-141 as well as the clinicopathological features of patients with IAAA were analyzed, and the factors influencing the prognosis of IAAA were analyzed by univariate and multiva-riate analysis. The expression levels of miR-183 and miR-141 were significantly downregulated in the lesions of patients with IAAA, and miR-183 and miR-141 levels in the lesion tissues of the IAAA patients were significantly lower than those in the adjacent tissues (P<0.05). The expression levels of miR-183 and miR-141 were not related to sex, age, history of hypertension, and alcoholism (P>0.05), but they were related to smoking history or aneurysm size (P<0.05). The overall survival rate of patients with IAAA was 41.6% (15/36). The multivariate analysis found that aneurysm size, low expression of miR-183, and low expression of miR-141 were independent factors affecting the prognosis of patients with IAAA. In conclusion, the expression levels of miR-183 and miR-141 in the lesion tissues of IAAA are low, and the lower the expression level is, the worse the prognosis gets. miR-183 and miR-141 can be used as predictors of prognosis in patients with IAAA.
