miR-328 expression is upregulated in PF. a HE staining of lung tissue 3 d, 14 d and 28 d after modeling (400 × ). b Masson staining of lung tissue 3 d, 14 d and 28 d after modeling (400 × ). c, miR-328 levels 3 d, 14 d and 28 d after modeling examined by RT-qPCR. * p < 0.05 vs. the sham group; miR-328, microRNA-328; HE, hematoxylin-eosin; RT-qPCR, reverse transcription quantitative polymerase chain reaction; and PF, pulmonary fibrosis. All results were measurement data and were analyzed using one-way analysis of variance. The results are expressed as the mean ± standard deviation; the sham group, n = 18; and the PF group, n = 18
