a Representative Nile red staining of macrophages. b Quantification of lipid changes. Data were presented as the mean？+？SD. n？=？8 per group. **P？<？0.01, independent samples t-test. c Changes in metabolic profiles of macrophages treated with oleate and RSV. n？=？5, 5, 5, and 3 in the control, oleate, oleate？+？RSV and QC (quality control) groups, respectively. d Relative standard deviation (RSD) distribution of ion peaks in 3 QC sample
