RESUMEN
Objective To investigate the changes of serum stromal cell‐derived factor‐1α (SDF‐1α) in patients with diabetic peripheral neuropathy (DPN) and the influence of mouse never growth factor (MNGF) on the levels of serum SDF‐1α. Methods 180 patients with type 2 diabetes (T2DM ) were divided into T2DM with DPN (DPN group ,n=92) and T2DM without DPN (T2DM group ,n=88). 90 healthy people were select as normal control (NC group). DPN group was divided into 47 cases of MNGF treatment (A) subgroup and 45 cases of basic treatment (B) subgroup. The levels of serum SDF‐1αwere measured using ELISA method. The relationships between the levels of serum SDF‐1αand SOD ,TGF‐β1 , hsC‐RP ,and GAP‐43 were analyzed. After treatment ,the levels of serum SDF‐1α in A and B subgroups were compared. Results Compared with NC group [(0.91 ± 0.37)μg/L] ,the levels of serum SDF‐1αin T2DM and DPN group were higher [(2.58 ± 0.58) μg/L and(1.71 ± 0.43)μg/L ,respectively ,P0.05] .Multiple stepwise regression analysis showed that HbA1c ,hsC‐RP and PSCV were the independent factors related with the levels of SDF‐1αin DPN patients. Conclusion The levels of serum SDF‐1αin DPN patients are lower than in T2DM patients without DPN. MNGF may increase the level of serum SDF‐1α.
