RESUMO
Objective To evaluate the effect of stent implantation using Multimodal CT in patients with MCA and ICA stenosis. Methods Twenty-six patients with ischemic cerebrovascular disease who received MCA or ICA stent implantation in ChongQing xinqiao Hospital were recruited. Multimodal Stroke Assessment Using CT Score (MOSAIC) was used to evaluate the Neuroimaging data before stent implantation and Alberta Stroke Program Early CT Score (ASPECTS) to evaluate the time to peak (TTP) of CTP before and after stent implantation. Results Patients were divided into 4 groups based on scores: 4 scores, 5 scores, 6 scores, and 7 scores groups. the improvement degree was increase by 31.7%±14.17%、38.6%±15.73%、43.3%±10.3%、358.6%±13.45% in 4 scores, 5 scores, 6 scores, and 7 scores groups, respectively. The paired t test demonstrated that there were a statistically significant difference among four groups(H=10.673, P <0.05). Preoperative MOSAIC score was positively correlated with the improvement of ASPECT score for TTP, with a correlation coefficient of 0.579 ( P <0.002). Conclusions Multimodal CT is a sensitive assessment for the evaluation of ischemic cerebrovascular disease and patients with a higher MOSAIC score may benefit more from stent implantation.
RESUMO
Objective To explore the mechanism of IL-6 in EAE. Methods 25 female Wistar rats were randomly divided into 2 groups, EAE group( n=15 ) and normal control group( n=10). The expression of IL-6, TNF-αtand TGF-β of the two groups rots were ob-served by immunohistochemistry staining, and then correlation analysis of the expression of IL-6, TNF-αtandTGF-β was made. Results There was negative correlation between gray scale of IL-6 and symptom scores( r=-0.953, P＞0.05). IL-6 and TGF-β had no statistical-ly significant correlation ( r=-0.492, P＞0.05). There was negative correlation between gray scale of TNF-α and symptom scores( r=-0.978, P＜0.05), and both of the correlation between TNF-α and TGF-β ( r=-0.502, P＞0.05), TGF-β and scores( r=0.470,P＞0.05 ) were not statistically significant. Conclusions IL-6 may participate in EAE as a inflammatory factor.
