Abstract Objective To detect the levels of serum hypoxia inducible factor-1α (HIF-1α), myelin basic protein (MBP), high sensitive C reactive protein (hs-CRP) and oxidative stress response in patients with diabetic peripheral neuropathy, and analyze the correlation among them. Methods 90 cases of patients with diabetic peripheral neuropathy treated in the Fifth Atfiliated Hospital of Xinjiang Medical University ("our hospital" for short) from July 2015 to July 2016 were selected as the study group. 80 healthy cases matched by age and gender in our hospital at the same time were selected as the control group. General biochemical indexes, levls of serum HIF-1α, MBP, hs-CRP, oxidative stress levels of super oxide dismutase (SOD), reduced glutathione (GSH), and malonaldehyde (MDA) were detected and compared between the two gorups. The multivariate Logistic regression analysis was used to analyze the influence factors of diabetic peripheral neuropathy. Spearman correlation test was used to analyze the correlation among serum HIF-1α, MBP, hs-CRP and SOD, GSH, MDA in the study group. Results The levels of total cholesterol (TC), triglyceride (TG), fasting blood glucose (FPG), glycosylated hemoglobin (HbA1c), fasting insulin (FINS) in the study group were significantly higher than those in the control group (P < 0.05). The levers of serum HIF-1α, MBP and hs-CRP in the study group were significantly higher than those in the control group, the differences were statistically significant (P < 0.05). The levels of serum SOD and GSH in the study group were significantly lower than those in the control group (P < 0.05), and the serum MDA level in the study group was significantly higher than that in the control group (P < 0.05). The multivariate Logistic regression analysis showed that age, duration of diabetes, TC, TG, FPG, HbA1c, FINS, MBP, hs-CRP, HIF-1α, MDA were independent risk factors of diabetic peripheral neuropathy (P < 0.05), SOD and GSH were protective factors of diabetic peripheral neuropathy (P < 0.05). Spearman correlation analysis showed that serum HIF-1α, MBP and hs-CRP in study group were positively correlated with MDA level (r=0.547, 0.624, 0.685, P < 0.05), and which were negatively correlated with SOD and GSH levels (r=-0.565, -0.583, -0.592, r=-0.492, -0.551, -0.572, P < 0.05). Conclusion The higher levels of serum HIF-1α, MBP and hs-CRP levels and oxidative stress are involved in the occurrence and development of diabetic peripheral neuropathy, which can be taken as clinical diagnostic bio-markers in patients with diabetic peripheral neuropathy, and provide theoretical basises for clinical intervention.
