Role of Neuron-Specific Enolase, D-Dimer and C-Reactive Protein in the Cranial Nerve Injury After Surgery of Posterior Fossa Tumor

Abstract

Cranial nerve injury after posterior cranial fossa tumor surgery (PCFTS) is a common symptom in clinic. Intracranial pressure (ICP) monitoring has been widely used in patients with severe posterior cranial fossa injuries. By establishing a rat model of PCFT, we explore the correlation between neuron-specific enolase (NSE), D-Dimer (D-D) and C-reactive protein (CRP) and provide the better clinical reference to cranial fossa injury treatment. 30 SD female rats aged 20–22 months; randomly divided them into control groups and experimental groups and experimental rats were further divided into 12 for moderately increased group (21–40 mmHg) and 8 for severely increased group (>40 mmHg) to measure NSE, D-D, and CRP and analyze their relationship. NSE, DD, and CRP in severely increased group and moderately increased group were significantly higher than those in control group. NSE (103.69±7.84) μg/L, DD (1.52±0.25) mg/L, CRP (47.63)±8.59) mg/L in severely increased group was significantly higher than moderately increased group (NSE (61.77±30.11) μg/L, DD (0.97± 0.37) mg/L, CRP (30.65± 9.56) mg/L) (P < 0.05). ICP is positively correlated with NSE, DD and CRP (r = 0.775, P = 0.000, intracranial pressure=18.589+0.254NSE; r =0.872, P =0.000, IC=10.564+0.254 DD; r =0.825, P =0.000, ICP = 9.73+0.774CRP). There is a positive correlation between cranial nerve injury and NSE, D-dimer and CRP after PCFTS. It can be evaluated by detecting the above values to assess the degree of cranial nerve injury so as to predict the patient’s condition.
