Abstract:Objective To explore the effect of acupoint application of Jingyi Anshen Powder on neurotransmitters in rats with insomnia. Methods According to the random number table method, 64 male rats were divided into four groups: control group (n = 16), model group (n = 16), blank group (n = 16) and experimental group (n = 16). Control group was intraperitoneally injected with 0.9% Sodium Chloride Solution (1 mL/100 g) once a day for 2 days, and fed continuously for 7 days without any intervention. Model group, blank group and experimental group were all injected intraperitoneally with P-phenylalanine (PCPA) once a day for two consecutive days to create a sleep deprivation model. After molding, model group was fed for 7 days without any intervention. After molding, in blank group, blank film was applied to shenque and neiguan acupoints once a day, 30 minutes a time for 7 days. After molding, in experimental group, Jingyi Anshen Powder was applied to shénquē and nèigu?觀n acupoints once a day for 30 minutes for 7 days. On the 8th day of the experiment, the rats were decapitated, the brain tissues were taken out after craniotomy, the hypothalamus was separated, washed and chopped, and the supernatant was taken from the homogenate. Contents of 5-hydroxytryptamine (5-HT), 5-hydroxyindoleacetic acid (5-HIAA), dopamine (DA) and noradrenaline (NANE) were measured by enzyme-linked immunosorbent assay. Results The exhaustion time of model group, blank group and experimental group was shorter than that of control group, and the despair time of model group, blank group and experimental group was longer than that of control group, the differences were statistically significant (P < 0.01). The exhaustion time of blank group and experimental group was longer than that of model group, and the desperation time of blank group and experimental group was shorter than that of model group, the differences were highly statistically significant (P < 0.01). The contents of 5-HT in model group and blank group were lower than that in control group, the contents of 5-HT in experimental group was higher than that in model group and blank group, the differences were statistically significant (P < 0.05 or P < 0.01). The contents of 5-HIAA in model group and blank group were lower than that in control group, while the content of 5-HIAA in experimental group was higher than that in model group, the differences were highly statistically significant (P < 0.01). DA contents of hypothalamus in model group and blank group were higher than that in control group, DA content of hypothalamus in experimental group was lower than that in model group, the differences were highly statistically significant (P < 0.01). The contents of hypothalamic NANE in model group and blank group were higher than that in control group, the contents of hypothalamic NANE in experimental group were lower than that in model group and blank group, the differences were statistically significant (P < 0.05 or P < 0.01). Conclusion Jingyi Anshen Powder is applied to the acupoints of insomnia rats to improve sleep by affecting the changes of the level of neurotransmitters in the hypothalamus.
