Effects of Feikang granules on inflammatory cytokine mRNA levels in lung tissue. 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. These results were from the rats in each group of control (n = 4), COPD (n = 6), low dose (n = 5), middle dose (n = 5), high does (n = 5) of Feikang granules and dexamethasone (n = 5)
