Diffusion tensor imaging predicting neurological repair of spinal cord injury with transplanting collagen/chitosan scaffold binding bFGF.

Prognosis and treatment evaluation of spinal cord injury (SCI) are still in the long-term research stage. Prognostic factors for SCI treatment need effective biomarker to assess therapeutic effect. Quantitative diffusion tensor imaging (DTI) may become a potential indicators for assessing SCI repair.

Collagen/heparin sulfate scaffolds fabricated by a 3D bioprinter improved mechanical properties and neurological function after spinal cord injury in rats.

Effective treatments promoting axonal regeneration and functional recovery for spinal cord injury (SCI) are still in the early stages of development. Most approaches have been focused on providing supportive substrates for guiding neurons and overcoming the physical and chemical barriers to healing that arise after SCI. Although collagen has become a promising natural substrate with good compatibility, its low mechanical properties restrict its potential applications.

[Effect of Panax NotoginSeng Saponins on motor evoked potentials of spinal cord injured rats with motion function].

Objective: To investigate the effect of Panax NotoginSeng Saponins(PNS) on functional recovery of rats with spinal cord injury (SCI) after exercise.

Methods: SD normal rats were randomly divided into normal control group (Normal) and control group (Sham), spinal cord injury (SCI) and spinal cord injury (SCI) + panax notoginseng saponins group (PNS) (=8). All rats were given basso beattie bresnahan motor function score (BBB) and motor evoked potentials (MEP) examination to observe rat hind limb motor function recovery before operation and 1,3,7,14,21,28 days after operation.
