[0155] (1) Main method

[0156] 1. Drug configuration

[0157] (1) Propofol: Propofol: 10mg / ml, that is, 0.01mg / ul, take 4ul of propofol and dilute to 200ul to be 0.0002mg / ul (A) (the following is the dose for one well).

[0158] (2) S-Nitrosoacetylpenicillamine (SNAP): Add 1.25ml of dimethyl sulfoxide to 25mg of SNAP to aid dissolution, and then add 1.25ml of water (A0.01mg / ul).

[0159] (3) 2.7-dichlorohydrofluorescein (DCFH-DA): a concentration of 0.1mmol / l is formulated, and the total volume in each well is 101ul. According to the formula mmol / L=mg / M, each The dose of DCFH-DA in the well is 0.0049216 mg, if these doses are obtained in 1 ul, the concentration of DCFH-DA should be 4.9216 mg / ml, so 5 mg of DCFH-DA was weighed and dissolved in methanol.

Abstract

The invention discloses application of a small dose of propofol in preparing products for preventing and curing post-traumatic stress disorder (PTSD). Stress disorder and its related diseases include acute stress disorder (ASD) and PTSD. According to the test of injecting a small dose of propofol in the abdominal cavity of a PTSD pattern animal, the small dose of propofol has function of relieving fear, anxiety and learning and memory impairment of the PTSD pattern animal, and can decrease expressions of inducible nitric oxide synthase (iNOS) and neurons nitric oxide synthase (nNOS) which are caused by strong stress, increase expression of brain derived neurotrophic factor (BDNF) which plays an important role in neuroplasticity regulation and reduce release of nitric oxide (NO) of glioma cell of the pattern animal greatly. Accordingly, propofol with the advantages of quick action, quick metabolic clearance and no residues has good application prospect.

Description

technical field [0001] The present invention relates to the application of propofol in stress disorder and related diseases thereof, in particular to the application of low-dose propofol in the preparation of prevention, alleviation and / or treatment of post-traumatic stress disorder syndrome (Post-traumatic stress disorder, PTSD ) use in medicine. Background technique [0002] PTSD refers to a mental disorder that appears delayed and persists for a long time after an individual experiences or witnesses a major traumatic event. Associative stimulus. [0003] PTSD was first discovered in war veterans, but serious natural disasters, terrorist attacks, major traffic accidents, violent personal attacks, and major epidemics can all lead to the occurrence of PTSD. The epidemiological survey in 2010 showed that the incidence rate of PTSD in the United States was 7-8%, and the incidence rate in active servicemen of the US military was 14-16%. The incidence rate of PTSD in 260 orph...
