The present study aimed to investigate the effect of traditional Chinese kidney reinforcing and marrow-beneficial medicine (KRMB) on the prevention and treatment of abnormal bone metabolism and osteoporosis (OP) resulting from spinal cord injury (SCI). Rat models of OP following SCI were surgically established. The rats were randomly divided into five groups: Normal; sham operation + KRMB; normal + KRMB; SCI + KRMB; and SCI model group. Bone mineral density (BMD), and the expression of bone gamma-carboxyglutamic-acid containing protein (BGP), hepcidin mRNA and bone sialoprotein (BSP) were recorded at 1, 2, 4, 6, 8 and 10 weeks after the operation. BMD expression in the SCI model group was significantly lower compared with the normal, sham + KRMB and normal + KRMB groups at 4, 6, 8 and 10 weeks (P<0.01), and was significantly lower than that in the SCI + KRMB group at 6 (P<0.05), 8 and 10 weeks (P<0.01). The level of serum BGP in the SCI model group was significantly higher compared with the normal, sham + KRMB and normal + KRMB groups at each time point (P<0.01), and lower than the SCI + KRMB group (P<0.01). The SCI + KRMB group was significantly higher than the normal, sham operation + KRMB and normal + KRMB groups (P<0.01). Hepcidin mRNA expression in the rat livers in the normal, sham + KRMB and normal + KRMB group was significantly higher than that in the SCI + KRMB group and SCI model group at each time point (P<0.01). Hepcidin mRNA expression in the SCI + KRMB group was significantly higher than that in the SCI model group at 1 week (P<0.01), and significantly higher than the SCI model group at 2, 4, 6, 8 and 10 weeks (P<0.01). BSP expression in the SCI model group was significantly higher than that in the normal, sham + KRMB and normal + KRMB groups at each time point (P<0.01). BSP expression in SCI model group was higher than that in the SCI + KRMB group at 1 (P<0.05), 2, 4, 6, 8 and 10 weeks (P<0.01). In conclusion, KRMB traditional Chinese medicine may have a curative effect on secondary OP resulting from SCI.

Background: An accurate knowledge of a patient's risk of cord-level intraoperative neuromonitoring (IONM) data loss is important for an informed decision-making process prior to deformity correction, but no prediction tool currently exists.
Methods: A total of 1,106 patients with spinal deformity and 205 perioperative variables were included. A stepwise machine-learning (ML) approach using random forest (RF) analysis and multivariable logistic regression was performed.
Purpose: We aimed to investigate the role of gallic acid treatment on spinal cord tissues after spinal cord injury (SCI) and its relationship with endoplasmic reticulum (ER) stress by histochemical, immunohistochemical, and in-silico techniques.
Methods: Thirty female Wistar albino rats were divided into three groups: sham, SCI, and SCI+gallic acid. SCI was induced by dropping a 15-g weight onto the exposed T10-T11 spinal cord segment.

Prior knowledge changes how the brain processes sensory input. Whether knowledge influences initial sensory processing upstream of the brain, in the spinal cord, is unknown. Studying electric potentials recorded invasively and noninvasively from the human spinal cord at millisecond resolution, we find that the cord generates electric potentials at 600 hertz that are modulated by prior knowledge about the time of sensory input, as early as 13 to 16 milliseconds after stimulation.

Purpose: Non-fusion surgical options for pediatric scoliosis management such as vertebral body tethering (VBT) offer an alternative to spinal fusion. With this study, we aim to evaluate the postoperative outcomes in boys versus girls who have undergone VBT. Our hypothesis is that girls and boys will have similar outcomes by 2-year follow-up.

Cognitive impairment (CI) in multiple sclerosis (MS) is only partially explained by whole-brain volume measures, but independent component analysis (ICA) can extract regional patterns of damage in grey matter (GM) or white matter (WM) that have proven more closely associated with CI. Pathology in GM and WM occurs in parallel, and so patterns can span both. This study assessed whether joint-ICA of GM and WM features better explained cognitive function compared to single-tissue ICA.
