Abstract: The present invention discloses a method for preparing a nanocomposite material for toe cap production. The nanocomposite material is made of graphene, carbon nanotubes, fiber composition, a silane coupling agent, acetic acid, acrylate rubber, a dispersant, polyethylene resin, nano-silicon carbide, calcium stearate, zinc stearate, talcum powder, modified boron nitride, a curing agent and other materials. The preparation method is convenient and simple and is suitable for large-scale production; the nanocomposite material has high toughness and strength and good water resistance, wear resistance and aging resistance; all materials have a good combination effect with the fiber composition, therefore the nanocomposite material has good mechanical properties and a light weight.

Abstract: The disclosure provides a non-therapeutic method for regulating DAT gene expression in a cell, which includes the step of increasing or decreasing an amount of a miR-132/212 in the cell; further provides a use of the above miRNA, an enhancer thereof or an attenuator thereof in preparing a drug for regulating uptake of dopamine by a cell; and an application of the above miRNA, the enhancer thereof or the attenuator thereof in preparing a drug for treating psychoactive substance addiction.
