Objective: To observe the effect of electroacupuncture (EA) stimulation on the levels of a disintegrin and metalloproteinase with thrombospondin motifs-4 (ADAMTS-4) protein in the lumbar intervertebral disc tissue and serum in prolapsed lumbar intervertebral disc degeneration (PLIDD) rats, so as to explore its mechanism underlying improvement of intervertebral disc degeneration (IDD).

Methods: A total of 48 Sprague-Dawley rats were divided into sham operation (=12), model (=18) and EA (=18) groups. The PLIDD model was established by puncturing the lumbar discs (L4-L5, L5-L6) with a gauge-22 syringe needle.

Most studies on spinal cord neuronal injury have focused on spinal cord tissue histology and the expression of nerve cell damage and repair-related genes. The importance of the microcirculation is often ignored in spinal cord injury and repair research. Therefore, in this study, we established a rat model of intervertebral disc extrusion by inserting a silica gel pad into the left ventral surface of T13.

Mn-doped ZnS nanopatricles synthesized by solvothermal method were successfully coated with SiO2 shells of various thicknesses by hydrolysis reaction of tetraethyl orthosilicate (TEOS). The samples were characterized by X-ray diffraction (XRD), transmission electron microscopy images (TEM), X-ray photoelectron spectroscopy (XPS) and the room temperature photoluminescence (PL) spectra. When the ZnS : Mn nanoparticles were coated with SiO2 shells, an obvious increase in particle size and a clear shell of SiO2 can be observed.

In the present paper, ZnS : Ag nanoparticles were prepared with simple chemicals by hydrothermal method. XRD patterns indicated that the products have cubic zinc blende crystal structure. The particle diameters were calculated using the Scherer's formula, and the particle size showed a nonlinear increase with the rise of reaction temperature.
