Objective:To determine expression levels of ubiquitin C-terminal hydrolase-L1 (UCH-L1) and serum glial fibrillary acidic protein (GFAP) in patients with acute cerebral infarction and their clinical significance.Methods:A total of 80 patients with acute cerebral infarction in Chongqing Cancer Hospital from January 2014 to February 2016 were enrolled as an observation group.Another 80 healthy people served as a control group.The expression levels of UCH-L1 and GFAP in the 2 groups were detected.Results:Sensibility and specificity for UCH-L1 and GFAP were 75.0％,87.5％ and 81.3％,90.0％,respectively.Receiver operating characteristic curve areas of UCH-L1 and GFAP were 0.670 and 0.757,respectively.There were no significant significance in age,gender,drinking,smoke,diabetes,and hyperlipidemia in the 2 groups (P＞0.05).High blood pressure rate in the observation group was higher than that in the control group (P＜0.05).Spearson/Pearson analysis showed that serum UCH-L1 and GFAP levels were positively correlated with hypertension,but they were negatively correlated with sex,age,diabetes,hyperlipidemia,alcohol consumption,smoking,and other factors.General data at different time in the observation group was not statistically different (P＞0.05).The expression levels of UCH-L1 and GFAP in the observation group was higher than that in the control group (P＜0.05).UCH-L1 and GFAP levels at different time in the 2 groups were not statistically different (P＞0.05).UCH-L1 and GFAP levels in the light,medium,and heavy groups were higher than those in the control group (P＜0.05),while UCH-L1 and GFAP levels in the medium and heavy groups were higher than those in the light group (P＜0.05).There was significant difference between levels of UCH-L1 or GFAP and infarction size at different time in the observation group (P＜0.05).The results of Pearson correlation analysis showed that the levels of serum UCH-L1 and GFAP were positively correlated (r=0.634,P=0.001).Conclusion:The levels of serum UCH-L1 and GFAP are significantly increased at the early stage of acute cerebral infarction,and they have a certain correlation with the severity of cerebral infarction,which can provide a basis for early clinical diagnosis and treatment.
Résumé
Objective To explore the relationship between mRNA and protein expressions of PTTG, bFGF, P53 with tumorigenesis and invasiveness of pituitary adenoma. Methods The protein expressions of PTTG, bFGF, P53 were detected by immunohistochemical analysis, and their mRNA expressions were by reverse transcription polymerase chain reaction (RT-PCR) in 63 specimens of pituitary adenoma that was classified into invasive and non-invasive according to Wilson’s modified staging. Results Thirty-four specimens of pituitary adenoma were invasive and 29 non-invasive. The expressions of PTTG, bFGF, P53 were significantly higher in invasive pituitary adenoma than in non-invasive. The analysis of correlation showed that in invasive pituitary adenoma, the positive correlation exists between PTTG and bFGF mRNA (r=0.81, P
