Technical Field
The invention relates to application of bacillus coagulans in preparation of preparations for preventing or treating autism, in particular to application of bacillus coagulans in preventing or treating autism and reducing autism symptoms.
Background
Autism, also known as autism, is a developmental disorder disease that is characterized by three major types of core symptoms, namely: social interaction disorder, communication disorder, narrow interests and stereotypical repetitive behavior patterns, about 3/4 with mental retardation in infants. The disease course can last for a lifetime, is difficult to reverse, and the prevalence rate is increased year by year, thus causing huge economic and social burden to families and society. According to the statistics of the world health organization, the number of autistic children in continental China is about 60-180 ten thousand, and students consider that the actual number can reach 260-800 ten thousand. Autism has become an important disease causing mental disability in children, and with the rise of morbidity, enormous social and economic burden is being brought to families and society continuously.
The current treatment measures of the autism mainly comprise behavior intervention and drug intervention, training behavior intervention and psychological cognition treatment are mostly adopted clinically, and drugs are used for symptomatic treatment of accompanying mental symptoms. However, drug (e.g., risperidone, aripiprazole, etc.) intervention often causes various adverse reactions that affect patient treatment compliance and long-term maintenance of treatment. Autistic patients have weak self-control ability and are sensitive to adverse reactions, so the curative effect and safety of the medicine are particularly important for the treatment compliance and long-term maintenance of the treatment of the patients. Therefore, the search for a safe and effective drug for preventing or treating autism and reducing the symptoms of autism is a critical clinical need.

Application effects example 1: application of bacillus coagulans in treating autism
1, preparation of a model group:
1.1 the experimental animals were adult Wistar rats (purchased from the experimental animal center of vindolizhiwa): 30 adult SPF-grade Wistar female rats (with the body mass of 200-250g) and 30 male rats (with the body mass of 300-350 g). 50 male offspring rats (35 d after birth and 80-100g of body mass) are produced after the female rats and the male rats are combined.
1.2 mode of preparation referring to Schneider et al, female and male mice were housed overnight, vaginal smear was performed on the female mice the next morning, and a female patient who found a vaginal embolus was scored as day 1 of pregnancy, and pregnant female mice were individually bred. Pregnant female mice are randomly grouped according to the number of model groups and control groups which are 4:1, and on the 12.5 th day, the pregnant female mice of the model groups are injected with sodium Valproate (VPA) in one time in the abdominal cavity at the dose of 600mg/kg, and the pregnant female mice of the control groups are injected with physiological saline in the same amount in the abdominal cavity. The mice born by the pregnant mice of the model group are the autism model group, and the mice born by the pregnant mice of the control group are the control group. The day 1 after birth of the young mouse was designated as P1. Establishing a rat autism model.
1.3 the preparation result of the model group is successful in molding.
2 drug treatment experiment:
2.1 Experimental method 40 mice with autism of 35 days old (P35) and 10 mice in control group were randomly selected. Wherein the control group newborn mice are normal control group (n ═ 10), and the newborn mice of autism group are randomly divided into Bacillus coagulans group CGMCC1207, Bacillus coagulans group CGMCC1.2407, Bacillus bifidus group, and model control groupAnd 4 groups (n is 10). The treatment groups and the control group are fed with the same basic feed under the same feeding conditions, and the Bacillus coagulans group and the Bifidobacterium group have the bacteria content of 1 × 1060.5mL of CFU/mL (0.9% physiological saline is used for preparing bacterial powder) bacterial liquid is filled, and 0.5mL of 0.9% physiological saline is filled into the model control group and the control group every day for 2 weeks continuously. The effect of bacillus coagulans on the behaviourology of autistic rats was observed and compared with bifidobacteria.
2.2 behavioural assessment behavioural assessments were performed on the laboratory mice, including social interaction behavioural tests (social behavioural latency, duration, number), repetitive behavioural tests (cumulative time to reason hair) and learning memory tests (Moirrs water maze test). Selecting male mice which have the same birth time as the detection mice and the difference of the body mass less than 15g and are bred in cages as strange mice to assist in detecting social interaction behaviors. Data were statistically analyzed using SPSS 21.0.
