[Abstract]:Objective: To observe the effects of "Shen men" and "Sanyinjiao" on sleep - Awakening, emotional state and HPAA function of CRH rats injected with insomnia model, and to reveal the central mechanism and key neurotransmitters of electroacupuncture in the treatment of insomnia. Methods: the healthy and clean SD rats were screened out of the qualified experimental rats according to the test of body weight and open field test. The qualified experimental rats were randomly divided into blank group, false injection group, CRH model group and CRH electroacupuncture group. In the CRH model group, the rats in the CRH electroacupuncture group were injected with the lateral ventricle with CRH to establish the insomnia model. The false injection group only inserted the injection needle in the lateral ventricle, but did not give the drug. The lateral ventricle was injected after 24 hours of spontaneous activity and open field test. After the test was completed, the CRH electroacupuncture group was treated by Electroacupuncture of "Shen gate" and "Three Yin cross" treatment. The treatment was started at 20:00 every night, 1 times a day and 4 days. After the treatment, the spontaneous activities of 24 hours and the open field test were carried out for the rats in each group. After the test of behavior, the blood of the femoral artery and the thalamus, brain stem were taken and the enzyme linked immunosorbent assay was used to detect each group. Rat peripheral plasma ACTH, CORT, 5-HT and central CRH, 5-HT content.

Compared with the false injection group, the difference was statistically significant (P0.05) in the:CRH electroacupuncture group, the activity of electroacupuncture at night was significantly higher than that of the CRH model group. The difference was statistically significant (P0.05).2. open field experiment: (1) baseline: the score of the outer circumference, the score of the central lattice and the vertical score were all single factor. Difference analysis, the difference was not statistically significant, indicating that the results of the baseline field test were balanced and comparable. After the injection of the lateral ventricle, the score of peripheral blood in the CRH model group, the peripheral peripheral score of the CRH electroacupuncture group was significantly lower than that in the blank group, and all had statistical meaning (P0.05); the CRH model group, the peripheral peripheral score of CRH electroacupuncture group were scored and Compared with the false injection group, the score of the central lattice was statistically significant (P0.05). The score of central grid in the CRH model group was more than that in the blank group. The score of the central grid in the CRH electroacupuncture group was significantly higher than that in the blank group. All the scores were statistically significant (P0.05). The score of the central grid in the CRH electroacupuncture group was slightly more than that of the false injection group. Study significance (P0.05); vertical score: CRH model group, the vertical score of CRH electroacupuncture group was significantly increased compared with the blank group, all had statistical significance (P0.05):CRH model group, the vertical score of CRH electroacupuncture group was significantly increased compared with the false injection group (P0.05): after treatment: the peripheral score: CRH model group rats open. Compared with the blank group, the score of the OTC week in the CRH electroacupuncture group was significantly lower than that in the blank group (P0.05). The score of the open field week in the CRH model group was significantly lower than that in the false injection group. The score of the open field week after the electroacupuncture group of the CRH electroacupuncture group was compared with that of the false injection group. Compared with the CRH model group, the score of the rats in the CRH electroacupuncture group was significantly higher than that of the CRH model group (P0.05), and the central grid score of the CRH model group was significantly higher than that in the blank group, and the central grid in the CRH model group was significantly higher than that in the blank group, and the center of the CRH electroacupuncture group was in the center of the electroacupuncture group after the treatment. The score of the grid was a slight increase compared with that in the blank group (P0.05); the score of the central grid in the CRH model group was significantly higher than that in the false injection group. The score of the central grid in the electroacupuncture group of the CRH electroacupuncture group was slightly higher than that in the false injection group, and all had statistical meaning (P0.05), and the central lattice of the electroacupuncture group of the CRH electroacupuncture group after the electroacupuncture treatment. The score was significantly lower than that of the CRH model group (P0.05), and the vertical score of the rats in the CRH model group was significantly higher than that in the blank group. The vertical score of the open field after the electroacupuncture group of the CRH electroacupuncture group was slightly increased compared with the blank group (P0.05), and the open field of the CRH model group was perpendicular to the open field. The scores of the rats in the CRH electroacupuncture group increased slightly compared with those in the false injection group, and there was a statistical significance (P0.05). The vertical score of the electroacupuncture group in the CRH electroacupuncture group was significantly lower than that in the CRH model group, with a statistically significant (P0.05):3. plasma neurotransmitter content: (1) the amount of 5-HT, ACTH, CORT in the peripheral plasma of the CRH model group was significantly increased with the blank group, and the difference was statistically significant (P0.05). (2) the plasma 5-HT, ACTH, CORT in the peripheral plasma of the CRH electroacupuncture group were significantly decreased compared with the CRH model group, and the difference was statistically significant (P0.05) 4. central nerve delivery. Content: (1) CRH model group rats thalamus, brain stem neurotransmitter CRH content and blank group, compared with the false injection group was significantly increased, the difference was statistically significant (P0.05); CRH electroacupuncture group rats after electroacupuncture treatment of thalamus, brainstem neurotransmitter CRH content compared with the CRH model group significantly decreased, the difference was statistically significant (P0.05); (2) CRH model The content of 5-HT in the thalamus and brainstem neurotransmitter in the rat model group was significantly lower than that in the blank group, and the difference was statistically significant (P0.05). The content of 5-HT in the thalamus and brainstem neurotransmitter in the CRH electroacupuncture group was significantly higher than that in the CRH model group, and the difference was statistically significant (P0.05). Conclusion: the lateral ventricle injection of CRH can be made. As a model of insomnia, the hypothalamus pituitary adrenal axis excitability of the rat model of insomnia is increased; Electroacupuncture "Shen gate" and "Three Yin" are used to treat insomnia by adjusting the hyperexcitation of the hypothalamus pituitary adrenal axis. The paraventricular nucleus CRH of the inferior colliculus is the key substance of electroacupuncture in the treatment of insomnia.
