Symptomatic carotid stenosis (sCS), a common cause of transient ischemic attack (TIA), is correlated with higher stroke risk. We investigated the frequency and associated factors of sCS in patients with TIA and the association between sCS and stroke risk following TIA. ⋯ SCS appears to be associated with a higher risk of stroke in patients with TIA defined according to the tissue-based definition.

Multiple sclerosis (MS) is one of the main chronic inflammatory diseases of the central nervous system that causes functional disability in young people. The aim of this study was to investigate the neutrophil-to-lymphocyte ratio (NLR) in patients with MS and the relationship between the NLR and the severity of the disease. One hundred and two MS patients (31 patients were in relapse; 71 patients were in remission) and 56 healthy controls were included. ⋯ The NLRs were directly correlated with erythrocyte sedimentation rate levels (r = 0.795, p < 0.001). Logistic regression analysis with dichotomous EDSS score showed that a high NLR was an independent predictor of the progression of disability. The NLR may be a biomarker that has simple, quick, inexpensive and reproducible properties in MS to predict patient's prognosis.

Remote ischemic postconditioning (RIPostC) is a promising therapeutic intervention, which has been discovered to reduce ischemia/reperfusion (I/R) injury in heart, kidney, brain and skeletal muscle experimentally. However, its potential protective mechanisms have not been well elucidated. The aim of this study was to investigate the protective effect of RIPostC in cerebral I/R injury and explore the new putative mechanisms of neuroprotection elicited by it. ⋯ RIPostC was generated by three cycles of 5-min reperfusion/5-min occlusion of the bilateral femoral artery on the bilateral limbs at the onset of middle cerebral artery reperfusion. RIPostC significantly improved neurological outcome, lessened infarct volume and brain edema, upregulated the expression of Nuclear factor erythroid 2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1) and quinone oxidoreductase-1 (NQO-1) and activity of superoxide dismutase (SOD), and downregulaed the formation of malondialdehyde (MDA) (p < 0.05). Taken together, these findings demonstrated that RIPostC protected the brain from I/R injury after focal cerebral ischemia by reducing oxidative stress and activating the Nrf2-ARE (antioxidant response element) pathway.

Clinical Trial
Botulinum toxin A in the treatment of trigeminal neuralgia.
The aims of this study were to investigate the clinical effects and safety of botulinum toxin A (BTX-A) in treating trigeminal neuralgia and its influences on accompanied depression, anxiety, sleep disorders, and quality of life. ⋯ BTX-A treatment can significantly relieve the pain in trigeminal neuralgia patients; improve anxiety, depression, and sleep; and increase the quality of life. BTX-A treatment is a safe and effective method to treat classical trigeminal neuralgia.

Comparative Study
The clinical utility of multimodal MR image-guided needle biopsy in cerebral gliomas.
Our aim was to evaluate the diagnostic value of multimodal Magnetic Resonance (MR) Image in the stereotactic biopsy of cerebral gliomas, and investigate its implications. ⋯ Multimodal MR image-guided glioma biopsy is practical and valuable. This technique can increase the diagnostic accuracy in the stereotactic biopsy of cerebral gliomas. Besides, it is likely to increase the diagnostic yield but requires further validation.
