Occupational exposure to silica dust particles was the major cause of pulmonary fibrosis, and many miRNAs have been demonstrated to regulate target mRNAs in silicosis. In the present study, we found that a decreasing level of miR-411-3p in silicosis rats and lung fibroblasts induced by TGF-β1. Enlargement of miR-411-3p could inhibit the cell proliferation and migration in lung fibroblasts with TGF-β1 treatment and attenuate lung fibrosis in silicotic mice. In addition, a mechanistic study showed that miR-411-3p exert its inhibitory effect on Smad ubiquitination regulatory factor 2 (Smurf2) expression and decrease ubiquitination degradation of Smad7 regulated by smurf2, result in blocking of TGF-β/Smad signaling. We proposed that increased expression of miR-411-3p abrogates silicosis by blocking activation of TGF-β/Smad signaling through decreasing ubiquitination degradation effect of smurf2 on Smad7. BACKGROUND Deaths from prescription opioid overdose are dramatically increasing. This study evaluates the incidence, risk factors, and cost of new persistent opioid use after aortic valve replacement (AVR), mitral valve replacement (MVR), and mitral valve repair (MVr). METHODS Insurance claims from commercially insured patients who underwent AVR, MVR, MVr, or AVR and MVR/r from 2014 to 2016 were evaluated. New persistent opioid use was defined as opioid-naïve patients who filled an opioid prescription in the perioperative period and filled opioid prescriptions between 90 and 180 days postoperatively. Multivariable logistic regression identified risk factors for new persistent opioid use. Quantile regression evaluated the impact of new persistent opioid use on total health care payments in the 6 months after discharge. RESULTS Among 3,404 opioid-naïve patients undergoing AVR, MVR or MVr, 188 (5.5%) had new persistent opioid use. Livi
