Abstract:Objective To investigate the changes and clinical significance of FGF-21 and MIP-2 in idiopathic pulmonary fibrosis. Methods Eighty patients with idiopathic pulmonary fibrosis in our hospital from December 2013 to December 2018 were selected as the research objects. The pulmonary fibrosis tissue of the patients was taken as the research object, and the adjacent normal tissue was taken as the control. The levels of FGF-21 and MIP-2 were determined by Western blotting, while the levels of FGF-21 and MIP-2 mRNA were determined by RT-PCR. The relationship between pathologic feature and FGF-21 mRNA, MIP-2 mRNA between the two groups was compared. The related factors of idiopathic pulmonary fibrosis were analyzed by Logistic Regression analysis. The related factors of clinical prognosis of patients with idiopathic pulmonary fibrosis were analyzed by COX regression analysis. Results The levels of FGF-21 mRNA, MIP-2 mRNA of pulmonary fibrosis tissue were higher than those of normal tissue (P?0.05). There was no relationship between FGF-21 mRNA, MIP-2 mRNA and age, gender, smoking, BMI as well as disease courses (P?>?0.05). There was positive relationship between idiopathic pulmonary fibrosis and FGF-21 mRNA, MIP-2 mRNA (P?0.05) analyzed by Logistic Regression analysis. The high expression levels of FGF-21 mRNA and MIP-2 mRNA were independent factors affecting the clinical prognosis of patients with idiopathic pulmonary fibrosis analyzed by COX regression analysis. Conclusions The high expression levels of FGF-21 mRNA and MIP-2 mRNA are related factors in the occurrence of idiopathic pulmonary fibrosis, and are associated with clinical prognosis.
