Abstract: The present disclosure provides a kit and method for constructing a long-acting depression animal model. The present disclosure adopts Bacille Calmette-Guerin (BCG) (or Mycobacterium bovis (M bovis)) and low-dose pertussis toxin (PTX) for combined induction, which greatly reduces modeling cost. A mouse model constructed by the method of the present disclosure can clearly distinguish a time interval of pathological behaviors from a time interval of depression-like behaviors and has prominent face validity and predictive validity. The method of the present disclosure is simple and convenient and does not require a large number of tedious daily operations as the depression model construction by chronic unpredictable stress, chronic restraint stress, social defeat, mother-child separation, or the like. The mouse model of the present disclosure can provide a valuable long-term intervention window for research on antidepressant therapy.

Abstract: A light projection method with safety protection and a light projection device with safety projection. The light projection method (200) comprises: turning on a light source at a safe power level (S201); using a diffractive optical element to modulate light emitted from the light source so as to project a pattern onto a target surface (S202); acquiring the pattern (S203); determining whether the pattern is normal (S204); and if so, turning on the light source at a rated power level, wherein the rated power level is higher than the safe power level (S205). The invention enables an optical system to have a smaller size while ensuring safety of a user, simplifies a structure, reduces costs, and facilitates efficient utilization of optical energy.

Abstract: The present invention relates to use of gTso thal in manufacturing a medicament for the promotion of MS-275 to cross the blood-brain barrier (BBB), and belongs to the technical field of pharmaceutical preparation. Administration of the medicament manufactured by the use of the present invention in combination with MS-275 significantly increases MS-275 to cross the BBB into the brain tissue, and prominently promotes the accumulation of MS-275 therein.
