Serum miR-146a and miR-150 as Potential New Biomarkers for Hip Fracture-Induced Acute Lung Injury

Figure 2

Representative H&E sections of pulmonary tissues (magnification: 200×). At 24 h after treatment, the elderly sham group (a) and the younger sham group (b) had no obvious inflammation; however, the elderly fracture group (c) and the younger fracture group (d) show typical manifestations of acute lung injury. At 72 h after hip fracture, the lung inflammatory manifestations of younger fracture group (f) had subsided, but it was still obvious in the elderly fracture group (e).
