阿魏酸鈉的鎮(zhèn)靜催眠作用機制研究
[Abstract]:Insomnia is a common type of sleep disorder, which is a common clinical manifestation of various body, mental and behavioral diseases. According to the epidemiological survey, about 35.2% of Western countries have different levels of insomnia, and the rate of insomnia in China is also as high as 10% ~ 20%. The sleep disorder may cause serious harm to human health, long-term insomnia, not only cause depression, but also cause body fatigue, cause cognitive dysfunction, even destroy the function of the immune system, cause damage to the heart, interfere with blood glucose regulation, hormone secretion, etc., And even developed into mental depression. The causes of insomnia are related to the genetic factors, the living habits, the environment, the disease and the mental and psychological factors. The study of its pathogenesis indicated that 5-HT, NE, GABA and other central neurotransmitters, such as 5-HT, NE, GABA and other central neurotransmitters, were abnormal in the edge-cortex system. Sodium ferulate is a common drug for cardiovascular and cerebrovascular diseases. It is found that sodium ferulate has a sedative and hypnotic effect in foreign research and clinical observation. However, the effect of sodium ferulate on the 5-HT, NE, GABA and hippocampal neurons of the central neurotransmitters is not clear. Objective To study the effect and mechanism of sodium ferulate on the sleep improvement of insomnia rats by establishing a model of insomnia rats. Materials and Methods 1. The effect of sodium ferulate on the sleep time of rats induced by sodium pentobarbital was observed by intraperitoneal injection of p-chlorophenylalanine (PCPA), and the content of GABA,5-HT, NE, IL-1 and the expression of GABAAR1 m were measured. The pathological changes of the brain tissue of the rats were also observed. Experimental study of the relationship between the effect of sodium ferulate on the sleep and the nervous system of 5-hydroxytryptamine. The effects of sodium ferulate on the levels of 5-HT in the prefrontal cortex, the hypothalamus and the hippocampus of the rats were observed, and the effects of sodium ferulate on the sleep latency and sleep duration of the rats were observed with 5-HT-synthesized precursor materials 5-HTP and 5-HT synthetase inhibitor PCPA, respectively. The effects of sodium ferulate on the content of 5-HT (5-HT) and 5-HT1A receptor-encoding gene (5-HT1A) in the hypothalamus of rats were determined by Elisa method. The effect of sodium ferulate on the expression of 5-HT1A receptor-encoding gene, Sc6a4 and 5-HT1A, was investigated by RT-PCR. The mechanism of the effect of sodium ferulate on the level of GABA in the model rats. The rat brain stem, the hypothalamus, the frontal cortex and the hippocampus of the rat brain stem, the hypothalamus, the frontal cortex and the hippocampus were isolated by intraperitoneal injection of p-chlorophenylalanine (PCPA). The levels of GABA in the brain stem, the hypothalamus, the frontal cortex and the hippocampus of the rats were determined by the Elisa method. GS level;4. The effect of sodium ferulate on the rat hippocampal neurons and its mechanism of action. The effects of sodium ferulate on the protective effects of sodium ferulate on the nerve cells of the hippocampus were studied by means of MTT method. The effect of sodium ferulate on the apoptosis of the rat's hippocampal neurons was studied by means of intraperitoneal injection of p-phenylalanine (PCPA), and the effect of sodium ferulate on the structure of the mitochondria was observed by a transmission electron microscope. The effect of sodium ferulate on the activity of the mitochondrial ATP enzyme was determined. The mRNA and protein expression levels of Bcl-2 and Bax in the hippocampus of each group were detected by RT-PCR, and the mechanism of the action of sodium ferulate on the nerve cells in the hippocampus was discussed. Results 1. Sodium ferulate has a good effect on the general status, sleep quality and sleep-related neurotransmitters in the model of PCPA insomnia. Sodium ferulate can effectively improve the normal state of the model rat, shorten the sleep period, prolong the sleep time, improve the relative expression of the GABA,5-HT, IL-1, and the GABA m RNA, and can effectively reduce the NE level; Experimental study of the relationship between the effect of sodium ferulate on the sleep and the nervous system of 5-hydroxytryptamine. Sodium ferulate significantly increased the concentration of 5-HT and TPH in the prefrontal cortex, the hypothalamus and the hippocampus of the rats (P0.05). During the combined application of sodium ferulate and 5-HTP, the sleep latency of the sodium ferulate group and the 5-HTP group had a tendency to be shortened, but there was no significant difference in the duration of the sleep (P0.05). When the sodium ferulate and the 5-HTP were used in combination, The sleep latency and sleep duration of the rats were significantly different from those in the blank group (P0.05). In the combined application of sodium ferulate and PACA, the sleep latency of the sodium ferulate group was significantly shorter than that of the sodium ferulate group (P0.05). The latency of the PCPA group was significantly longer than that of the sodium ferulate group and the blank control group (P0.05). The experimental results of the sleep duration showed that compared with the blank group, The group of sodium ferulate could significantly prolong the sleep time of the rats (P0.05). The sleep duration of the PCPA group was significantly shortened (P0.05), and the difference between the combined group and the blank group was not statistically significant (P0.05). The concentration of 5-HIAA in the hippocampus, the hypothalamus and the prefrontal cortex of the sodium ferulate group was significantly higher than that in the blank group (P0.05). The ratio of the 5-HIAA/5-HT in the hippocampus and the hypothalamus was statistically significant (P0.05). The 5-HIAA/5-HT ratio in the prefrontal cortex was not statistically significant (P0.05). The expression of Sc6a4 in the hypothalamus of the sodium ferulate group was significantly decreased, and the expression of 5-HTR1A was significantly increased. Compared with the control group, the levels of GABA and GAD in different brain regions of the model group were significantly decreased, and the levels of Glu and GS increased significantly, and the levels of GABA and GAD in different brain regions of the model rats can be improved by the dosage groups of sodium ferulate, and the levels of Glu and GAD in different brain regions can be reduced, and the hypothalamus can be reduced. The results of the study of the protective effect of sodium ferulate on the nerve cells in the hippocampus of the rats with mitochondrial injury showed that the survival rate of the neurons in the hippocampus of the rats with the mitochondrial injury was significantly lower than that in the normal control group (P0.05). The results of the TUNEL staining showed that the sodium ferulate could decrease the apoptosis rate of the hippocampal neurons in the sleep deprivation model. The results of RT-PCR showed that the sodium ferulate could promote the expression of Bcl-2 mRNA and protein, and inhibit the expression of Bax mRNA and protein. And the apoptosis of the hippocampal neurons is inhibited. Conclusion 1. The effect of sodium ferulate on the general status and the quality of sleep in the model of PCPA insomnia may be achieved by increasing the level of GABA, inhibiting the excitation of neurons, increasing the 5-HT, reducing the NE level, and decreasing the NE level to inhibit the maintenance of NE. Sodium ferulate can play an important role in improving sleep by combining 5-HT precursor substance 5-HTP, antagonizing the 5-HT synthetase inhibitor PCPA in the brain, increasing the excitability of the 5-HT energy nervous system, inhibiting the expression of 5-HT transporter, and enhancing the expression of 5-HT receptor. The effect of sodium ferulate on the level of GABA in rats may be by influencing the expression level of GAD and GS in various parts of the brain tissue, inhibiting or promoting the mutual transformation between GABA and Glu, and changing the balance of Glu/ GABA ratio; Sodium ferulate can inhibit the apoptosis of the hippocampal neurons caused by sleep deprivation, so as to improve the sleep, and the mechanism of action is related to the promotion of the expression of Bcl-2 mRNA and protein and the inhibition of the expression of Bax mRNA and protein.
