The protein levels of the signaling molecules in the rats femoral heads of all groups. Compared with the group N, there were remarkable increases in the protein levels of TLR4, MyD88, NF-κB p65 and MCP-1 in the group B, and slight increases in the group A. The MCP-1 levels in groups B showed most significantly, there was no marked difference between group A and group N. Between group A and group B, the protein levels of MyD88 and NF-κB p65 had significant differences at each time point, and TLR4 expression at 8 and 10 weeks, MCP-1 expression at 10 and 12 weeks, all had significant differences. (P < 0.05: # vs. group N; ★ vs. group A; P < 0.01: * vs. group N; Δ vs. group A).
