Relative mRNA levels of different group analysed by real-time PCR. a, b, c, d are respectively melt curve of TGF-β1, TGFβ-R1, α-SMA, E-cadherin. Data presented are means ± SD (n = 6 ~ 8). CG = the control group, MG = the model group, and TG = the astragalus treatment group. Compared with CG, *P < 0.05, **P < 0.01. Compared with MG, ΔP < 0.05, ΔΔP < 0.01
