Changes of ubiquitin C-terminal hydrolase-L1 and glial fibrillary acidic protein levels in acute phase of cerebral infarction
摘要
Abstract
Objective To investigate the changes of ubiquitin C-terminal hydrolase-L1 (UCH-L1) and glial fibrillary acidic protein (GFAP)in acute phase of cerebral infarction. Methods From March 2011 to June 2012,95 patients with early cerebral infarction from the Neurology Clinic,the Emergency Department and the Cerebral Apoplexy Screening Project Base,and the Neurology Ward of Renhe Hospital were used as an infarction group;61 non-stroke subjects received physical examination in the Physical Examination Center of our hospital in the same period were used as a control group. The cerebral infarction group and the patients with cerebral infarction in different onset of time groups (an onset < 12 h group and an onset 12-24 h group),the different National Institutes of Health Stroke Scale (NIHSS)score groups (NIHSS 0 -4 group and NIHSS 5 -19 group),and the levels of UCH-L1 and GFAP in the control group were measured and compared among the groups. The receiver operating characteristic (ROC)curve was established. The cut-off values of the relevant parameters in the diagnosis of cerebral infarction,and the sensitivity and specificity of diagnosis were obtained. Results The UCH-L1 and GFAP values of the cerebral infarction group were all higher than those of the normal control group (0. 13[0. 09,0. 21]μg/ L vs. 0. 05[0. 02,0. 13]μg/ L,0. 030[0. 008,0. 130]μg/ L vs. 0. 004[0. 004,0. 020]μg/ L,Z values were 3. 62 and 4. 95 respectively;all P < 0. 01). The UCH-L1 and GFAP values of the NIHSS score 5 -19 group were higher than those of the NIHSS score 0 -4 group (0. 12[0. 08,0. 21]vs. 0. 09[0. 08,0. 18],0. 07 [0. 01,0. 11]vs. 0. 04[0. 01,0. 10];all P < 0. 05). There was no significant difference in the UCH-L1 and GFAP values between the onset 12 -24 h group and the onset < 12 h group (0. 12[0. 08,0. 21]μg/ L vs. 0. 09[0. 08,0. 18]μg/ L,0. 030[0. 010,0. 110]μg/ L vs. 0. 040[0. 008,0. 100]μg/ L;all P > 0. 05). The analysis results of ROC curve of UCH-L1 and GFAP for diagnosis of acute cerebral infarction showed that when the plasma UCH-L1 was ≥0. 18 μg/ L,the sensitivity and specificity of UCH-L1 were 68% and 74%respectively;When the plasma GFAP was ≥0. 11 μg/ L,the sensitivity and specificity of GFAP were 70% and 86% respectively. The area under the ROC curve of UCH-L1 and GFAP diagnosis of cerebral infarction were 0. 64 and 0. 71 respectively. Conclusions UCH-L1 and GFAP have obvious change in acute phase of cerebral infarction. UCH-L1 and GFAP may have certain correlation with the severity of stroke.关键词
