Methods A total of 124 patients with diabetic peripheral neuropathy were randomly divided into mecobalamin group (n = 41), observation group (n = 41) and observation group (n = 42). Mecobalamin group oral mecobalamin capsules; observed a group of oral mecobalamin capsule + calcium carbonate D_3 tablets + calcitriol soft capsule; observed two groups in the observation group 1 treatment based on intramuscular injection of rat nerve growth factor 30μg + Saline 2 mL, 1 time / d. The scores of Toronto clinical scoring system (TCSS) were evaluated before treatment and after 4 weeks of treatment. The electromyography was performed to record the median nerve and motor nerve conduction velocity MNCV) and median nerve, sensory nerve conduction velocity (SNCV). The clinical efficacy of the three groups were compared. Results After 4 weeks of treatment, the TCSS scores in the two groups were significantly higher than those before treatment [(9.92 ± 1.33), (9.35 ± 5.71), (5.86 ± 0.83), (3.56 ± 0.72) ± 1.26), (9.57 ± 1.24) points (P <0.05). The TCSS score of the two groups was lower than that of the mecobalamin group and the observation group 1 after treatment (P0.05) ; After 4 weeks of treatment, the patients in the mecobalamin group were observed for 1 group. MNCV [(42.34 ± 6.88), (43.62 ± 5.75), (48.19 ± 4.73) m / s] (39.66 ± 5.89) and (43.95 ± 5.95) m / s, respectively. The median SNCV [(39.52 ± 8.62), (40.25 ± 9.18) and (46.17 ± 6.97) m / 36.46 ± 6.35), (37.71 ± 6.12) and (42.47 ± 6.75) m / s, respectively, compared with that before treatment [median nerve MNCV: (40.82 ± 5.64), (41.27 ± 5.12) and (42.13 ± 4.36) m / The MNCV of the common peroneal nerve was (37.11 ± 4.35), (38.03 ± 4.88) and (37.21 ± 4.31) m / s respectively. The SNCV of median nerve was (37.57 ± 6.16), (38.15 ± 6.49) and (38.02 ± 4.05) m / ; The peroneal nerve SNCV: (35.06 ± 5.16), (36.05 ± 4.65), (37.08 ± 5.18) m / s] increased significantly (P <0.05) P <0.05), mecobalamin group and observation group 1 comparison There was no significant different (P> 0.05); The total effective rate was observed 2 (95.24%) was significantly higher than that observed 1 group (75.61%) and methyl cobalamin group (53.66%) (P <0.05). Conclusion The application of NGF in combination with vitamin D and mecobalamin in diabetic peripheral neuropathy patients can effectively reduce the TCSS score and improve the nerve transmission rate and therapeutic effect.
