Objective:To investigate the effect of carotid artery stenting (CAS) on cognitive function in patients with severe carotid artery stenosis.Methods:From January 2019 to December 2020, consecutive patients with severe carotid artery stenosis (stenosis degree ≥70%) treated in the Department of Neurology, Bozhou People's Hospital were selected. According to different treatment schemes, all patients were divided into a CAS group and a control group. The CAS group received CAS combined with the best drug treatment, while the control group only received the best drug treatment. The cognitive function was evaluated by Montreal Cognitive Assessment (MoCA) before treatment and at 6 months after treatment.Results:During the study, 52 patients with severe carotid artery stenosis were enrolled, including 37 patients in the CAS group and 15 in the control group. There were no significant differences in demographic and baseline clinical data between the two groups. All patients in the CAS group completed procedure successfully without any complications. MoCA score in the CAS group was significantly higher than that before treatment ( P<0.001), but not in the control group. There was no significant difference in MoCA score between the patients in the CAS group and the control group before treatment; the MoCA score in the CAS group was significantly higher than that in the control group at 6 months after treatment ( P=0.007). Conclusion:CAS may improve the short-term postoperative cognitive function of patients with severe carotid artery stenosis.

Objective:To explore the feasibility of U6 and Cel-miR-39 as reference genes for quantitative detection of microRNA (miRNA) in cerebrospinal fluid (CSF) of tuberculous meningitis (TBM), and validate the difference of miRNAs between tuberculous and viral meningitis (VM).Methods:The remaining CSF specimens after routine examination were collected in Beijing Chest Hospital of Capital Medical University. A total of 36 TBM and 34 VM patients were enrolled based on the information in the medical records. Total RNA were extracted from the CSF samples, and Taqman based real-time quantitative PCR (RT-CR) analysis were performed to determine the concentration of the miRNAs in CSF. GeNorm, NormFinder and Bestkeeper software were used for stability analysis of the two reference genes. 2 -ΔCt method was used to determine the relative gene expression. Accordance of repeated tests was analyzed by Pearson correlation test. Continuous variables were compared by the t-test. Results:Among the 70 samples, the average cycle threshold (Ct) value of U6 was 30.40±3.30, while the average Ct value of Cel-miR-39 was 21.49±0.70. The expression level of Cel-miR-39 was higher than that of U6. Correlation analysis showed good accordance of the repeated tests among the reference genes and target genes analysis in the randomly selected 10 samples ( r>0.931, P<0.001). Based on the analyses results of the three software, including GeNorm, NormFinder and Bestkeeper, Cel-miR-39 presented better stability in RT-PCR analysis and was more suitable as a reference gene for miRNA quantitative determination in CSF sample of TBM patients. The relative expression levels of the three target miRNAs were calculated using Cel-miR-39 as the reference gene, and miR-126-3p (1.13±0.41 vs 3.34±0.82, t=2.452, P=0.016), miR-130a-3p (0.56±0.10 vs 2.59±0.70, t=2.960, P=0.004) and miR-151a-3p (0.64±0.25 vs 2.11±0.33, t=3.536, P<0.001) were showed significant lower expression levels in CSF in TBM group than that in VM group. Conclusions:Cel-miR-39 can be used as a reference gene for quantitative detection of miRNAs in CSF of TBM patients. Significant differences were detected in expression level of miR-126-3p, miR-130a-3p and miR-151a-3p between TBM and VM group.
