The invention discloses the application of sulpiride in medicine for treating or preventing neurotoxicity caused by 3,4 methylenedioxymethamphetamine (MDMA). Giving sulpiride half an hour before giving MDMA to the experimental rats, giving sulpiride while giving MDMA to the experimental rats, giving sulpiride half an hour, 5 hours, and 12 hours after giving MDMA to the experimental rats, all can reduce the frontal lobe cortex. The depletion of 5-HT in the three brain regions of brain, hippocampus and striatum has obvious inhibitory effect on the down-regulation of SERTmRNA expression; the results of neuropathology show that sulpiride can also inhibit the reduction of silver-stained positive area caused by MDMA, and inhibit the expression of SERT mRNA. Down-regulate the expression of glial fibrillary acidic protein (GFAP), which indirectly reflects the reduction of nerve damage. The dose of sulpiride given is 40mg / kg-80mg / kg.

The invention relates to the technical field of fertilizers, and discloses zinc selenite sol as well as a preparation method and application thereof, and the zinc selenite sol is used for reducing the cadmium content in plants and increasing the selenium content. Chitosan is added into the sol, so that the action efficiency is improved, and the action time is prolonged; the zinc element is added, so that the growth of crops is ensured while heavy metals such as cadmium are inhibited. The zinc selenite sol is prepared by the following specific steps: 1) reacting selenium element with zinc salt to obtain a precipitate; 2) adding water into the precipitate, pulping and stirring, and carrying out ultrasonic treatment; 3) stirring, heating and reacting the collected liquid through hydrogen-type weakly acidic cation exchange resin, standing, cooling, and aging to obtain a zinc selenite sol precursor; 4) adding the zinc selenite sol precursor into a mixture of hydrogen peroxide and ethanol, and reacting to obtain a zinc selenite sol precursor, and 5) adding chitosan into the zinc selenite sol precursor, and rapidly stirring until the chitosan is dissolved to obtain the zinc selenite sol.
