Abstract：Objective: To investigate the effect of tibial transverse bone relocation on trauma repair in diabetic foot rats, and to detect the expression of factors related to the NGF/Akt/GSK3β pathway to elucidate its possible mechanism of action. Methods: Forty SPF grade rats were selected, of which 10 were in the control group and the remaining 30 were modeled as diabetic foot rats. 28 rats finally completed the modeling and were divided into model group (10 rats), tibial transverse bone transfer group (9 rats), and tibial transverse bone transfer + MK-2206 group (9 rats). Wound healing rate, serum biochemical indexes, fasting blood glucose, oxidative stress indexes, capillary number, proportion of EPCs, VEGF, inflammatory factors and NGF/Akt/GSK3β pathway-related protein expression were compared between the groups. Results: Compared with the control group, TNF-α, fasting glucose, CRP, LDL-C, MDA, TG, IL-6, TC, and GSK3β protein expression were elevated, and the levels of Akt protein expression, capillary count, NGF protein expression, SOD, EPCs ratio, HDL-C, VEGF, and trauma healing rate in the model and tibia transverse bone relocation+MK-2206 group decreased, (P<0.05); Compared with the model group, the ratio of EPCs, SOD, NGF protein expression, capillary number, HDL-C, Akt protein expression, VEGF, and wound healing rate levels were increased, and the levels of TNF-α, MDA, LDL-C, fasting glucose, GSK3β protein expression, TC, CRP, TG, and IL-6 were decreased in the tibia transverse bone relocation group (P<0.05); Compared with the tibial transverse bone transfer group, the TNF-α, fasting glucose, IL-6, TC, MDA, CRP, TG, GSK3β protein expression, and LDL-C levels were increased in the tibial transverse bone transfer + MK-2206 group, and the levels of VEGF, SOD, Akt protein expression, HDL-C, NGF protein expression, the proportion of EPCs, the traumatic wound healing rate, and the level of the capillary number were decreased (P<0.05). Conclusion: Transverse tibial bone relocation promotes trauma repair and improves the expression of serum biochemical indexes, oxidative stress, capillary count, and inflammatory factors in diabetic foot rats, and its mechanism may be related to the NGF/Akt/GSK3β pathway.
