Abstract:
Objective:To investigate the relationship between serum ubiquitin C-terminal hydrolase-L1 (UCH-L1) and neuroglobin levels and the prognosis of neurological function in coma patients after cardiopulmonary resuscitation, and to analyze their value in predicting the prognosis of patients.Methods:From February 2018 to June 2020, 45 comatose patients admitted to the Chengdu Third People′s Hospital of Sichuan Province after successful cardiopulmonary resuscitation were prospectively selected as the coma group, and 62 patients admitted to the emergency intensive care unit during the same period after successful cardiopulmonary resuscitation with consciousness recovered within 24 hours were selected as the control group.Serum UCH-L1 and neuroglobin levels were detected within 24 hours after admission.Glasgow coma Scale (GCS)and cerebral performance category(CPC)were used to evaluate coma severity and neurological prognosis.Spearman rank correlation analyzed the correlation between UCH-L1 and neuroglobin levels and GCS and CPC scores.Logistic regression analyzed the factors affecting the prognosis of neurological function in coma patients after cardiopulmonary resuscitation.Receiver operating characteristic curve (ROC) was used to analyze the value of UCH-L1 and neuroglobin in predicting the prognosis of neurological function in coma patients after successful cardiopulmonary resuscitation.Results:In coma group, serum UCH-L1((0.63±0.21) μg/L) and the concentration of neuroglobin ((89.34±21.35) mg/L) was higher than that in the control group ((0.27±0.08) μg/L, (32.13±9.21) mg/L), the difference was statistically significant( t=12.338, 18.846; all P<0.001). The levels of UCH-L1 and neuroglobin in mild, medium and severe coma groups were increased in turn, and the differences between the groups were statistically significant( F=86.430, 26.958; all P<0.001). The serum levels of UCH-L1((0.72±0.06) μg/L)and neuroglobin ((100.35±5.79) mg/L)in the group with poor neurological prognosis were higher than those in the group with good neurological prognosis((0.52±0.08) μg/L, (75.58±6.91) mg/L), and the differences between the groups were statistically significant( t=9.585, 13.086; all P<0.001). UCH-L1 and neuroglobin were negatively correlated with GCS score(rs=-0.685, -0.669; all P<0.001), and positively correlated with CPC score (rs=0.688, 0.670; all P<0.001). Multivariate Logistic regression analysis showed that low GCS score( OR=0.552, 95% CI: 0.392-0.776, P<0.001), high UCH-L1 ( OR=1.881, 95% CI: 1.276-2.773, P<0.001)and neuroglobin( OR=1.677, 95% CI: 1.206-2.331, P=0.001)were independently associated with poor neurological outcomes in coma patients after cardiopulmonary resuscitation .The AUC of combining UCH-L1 and neuroglobin in predicting poor neurological outcomes in coma patients after cardiopulmonary resuscitation was 0.954, which was higher than that of UCH-L1 and neuroglobin alone (0.821, 0.790) ( Z=2.351, 2.649; all P<0.05). Conclusion:After successful cardiopulmonary resuscitation, the levels of UCH-L1 and neuroglobin in coma patients are increased.High levels of UCH-L1 and neuroglobin are associated with coma severity and neurological dysfunction, which can be used as a potential biological indicator for prognosis evaluation of neurological function.
