Effects of Feikang granules on inflammatory cytokine mRNA levels in alveolar macrophages of COPD model rats. The mRNAs of TNFα, IL-6, TLR4 and TLR2 were measured. The data are shown as the mean ± the standard deviation (SD). ^∗p < 0.05 and ^∗∗p < 0.01 indicate statistically significant differences compared to the model group; ^##p < 0.01 indicate a statistically significant difference in model group compared with normal control group. All results were from 3 batches of culture mediums
