Rat model of severe contusion spinal cord injury was used to study the effect of single intravenous and intraspinal injection of human umbilical cord blood mononuclear cells on the restoration of motor function of the hind limbs. Recovery of the motor function of the hind limbs was assessed using load tests and open-field test according to BBB scale. Cell injection via both routes significantly improved (p≤0.05) the recovery of the motor function of the hind limbs by 35-40% relative to the level of "self-recovery"; the effects of intravenous andintraspinal administration did not differ significantly.

Parkinson's disease (PD) is a prevalent and challenging neurodegenerative disorder, and may involve impaired autophagy. Nuclear factor erythroid-2-related factor 2 (Nrf2) is crucial for regulating autophagy-related genes, maintaining cellular homeostasis. Electroacupuncture (EA), a complementary and alternative therapy for PD, has gained widespread clinical application.

Objective: Corpus callosum (CC) damage is the most consistent and typical change in early Parkinson's disease (PD), and is associated with various PD symptoms. However, the precise relationship between CC subregions and specific PD symptoms have not been identified comprehensively. In this study, we investigated the association between specific CC subregion alterations and PD symptoms using diffusion-weighted imaging.

In clinics, physical injuries to the spinal cord cause a temporary motor areflexia below lesion, known as spinal shock. This topic is still underexplored due to the lack of preclinical spinal cord injury (SCI) models that do not use anesthesia, which would affect spinal excitability. Our innovative design considered a custom-made micro impactor that provides localized and calibrated strikes to the ventral surface of the thoracic spinal cord of the entire CNS isolated from neonatal rats.

Purpose: To investigate the activity of default mode network (DMN), frontoparietal network (FPN) and cerebellar network (CN) in drug-resistant epilepsy (DRE) patients undergoing vagus nerve stimulation (VNS).
Methods: Fifteen patients were recruited and underwent resting-state fMRI scans. Independent component analysis and paired sample t-tests were used to examine activity changes of DMN, FPN and CN before and after VNS.
