Correlation of serum homocysteine metabolism and oxidative stress level with peripheral nerve damage in patients with Parkinson's disease
Objective:To analyze the correlation of serum homocysteine metabolism and oxidative stress level with peripheral nerve damage in patients with Parkinson's disease.Methods:A total of 58 patients with Parkinson's disease and 67 normal human beings were included in the study, levels of plasma homocysteine (Hcy) as well as superoxide dismutase (SOD), GSH, malondialdehyde (MDA) and other oxidative stress indexes were detected, and common peroneal nerve motor conduction velocity (MCV), latent period (LP) and amplitude (Amp) were determined.Results: Serum Hcy level of observation group was higher than that of control group while folic acid and vitamin B6 levels were lower than those of control group; serum oxidative indexes LHP, H2O2, AOPP and MDA levels were higher than those of control group while antioxidant indexes SOD T, SOD Mn, SOD Cu-Zn, GSH-PX, T-AOC and CAT levels were lower than those of control group; common peroneal nerve MCV and Amp values were lower than those of control group while LP value was higher than that of control group. Peripheral nerve damage parameter values in patients with Parkinson's disease were directly correlated with serum levels of Hcy metabolism indexes and oxidative stress indexes. Conclusions: Peripheral nerve damage in patients with Parkinson's disease is associated with hyperhomocysteinemia and oxidative stress disorder, and intervention in serum levels of Hcy and oxidative stress indexes is expected to become a new way for treatment of Parkinson's disease.
