The diabetic peripheral neuropathy pain model was constructed after 95 Sprague Dawley rats had been randomly divided among blank reference and model groups. Aescin low-dose group (0.5 mg/kg), aescin medium-dose group (1.0 mg/kg), aescin high-dose group (1.5 mg/kg), and positive control group (0.25 mg/ kg mecobalamin) were then randomly assigned to the simulation group following successful modeling. At the conclusion of the study, the mean sciatic nerve conduction velocity was determined, blood glucose in addition to the amount of inflammatory factors tumor necrosis factor-alpha, interleukin-6, and interleukin-1 were determined, and sciatic nerve cells from mice in all groups were collected for Western blot to identify the protein levels of high mobility group box 1 and receptor for advanced glycation end products. The mean sciatic nerve conduction velocity of the medium and high-dose groups of aescin was higher than those of the model control (p<0.05); rat blood glucose content, the contents of inflammatory factors interleukin-1 beta, interleukin-6 and tumor necrosis factor-alpha as well as the protein expression of high mobility group box 1 and receptor for advanced glycation end products in sciatic nerve tissue were lower and the body mass was higher than that of the model control group (p<0.05). Comparing the high-dose aescin group as well as the positive control group, there had been no discernible change in the aforementioned indices (p>0.05). Aescin is able to effectively improve the inflammatory response in the body by regulating high mobility group box 1-receptor for advanced glycation end products levels and slow down diabetic peripheral neuropathy caused by the inflammatory response.
