Plasma visfatin, associated with a genetic polymorphism −1535C > T, is correlated with C-reactive protein in Chinese Han patients with traumatic brain injury

► Visfatin genetic polymorphism is associated with plasma visfatin level. ► Visfatin genetic polymorphism is associated with plasma C-reactive protein level. ► Plasma visfatin level is highly correlated with plasma C-reactive protein level. ► Visfatin genetic polymorphism may be involved in the inflammatory process of TBI.
