Zhenzhu Tongluo pills can significantly improve the increased expression of inflammatory factors at the mRNA level in DRG of diabetic peripheral neuropathy rats. A Zhenzhu Tongluo pills can significantly improve the expression of TNF-α on mRNA level in DRG of diabetic peripheral neuropathy rats (n = 4, ^***p < 0.001 vs Control group; ^#p < 0.05, ^###p < 0.001 vs STZ group); B Zhenzhu Tongluo pills could significantly improve the expression of IL-1β on mRNA level in DRG of diabetic peripheral neuropathy rats (n = 4, ^***p < 0.001 vs Control group; ^#p < 0.05, ^##p < 0.01, ^###p < 0.001 vs STZ group); C Zhenzhu Tongluo pills could significantly improve the expression of IL-6 on mRNA level in DRG of diabetic peripheral neuropathy rats (n = 4, ^**p < 0.01 vs Control group; ^#p < 0.05 vs STZ group)
