The results showed that the levels of Cys C, SAA, HCY, and Lp-PLA2 in the PD group were significantly increased, while the levels of ALT, AST, BUN, TC, and LDL in this group were significantly lower than those in the control group (all P < 0.05),which remained significant after Bonferroni correction. Here, PLA2G7 is linked to Parkinson disease.
