[Abstract]:Objective To observe the effect of "Shugan Tiao Shen Shen" Acupuncture on abnormal sleep EEG in rats with post traumatic stress disorder (PTSD) sleep disorder model and the influence of the spatio-temporal pattern of abnormal nerve information coding in hippocampus CA1 and CA3 area and the ultrastructure of damaged neurons in the hippocampus of the rat model of posttraumatic stress disorder. The effect of acupuncture intervention on PTSD sleep disorder, and from the repair of the structure of hippocampal neurons and the function of reconstructing the neural network action potential, reveal the neurobiological mechanism of "Shugan Tiao Shen" acupuncture method affecting the PTSD sleep disorder, and provide scientific experimental basis for the efficacy of "Shugan Tiao Shen" needle therapy for the treatment of PTSD sleep disorder. 120 SD rats were randomly divided into two groups, the first group and 70 rats were randomly divided into the blank group, the operation group, the model group, the grab group, the acupuncture group and the western medicine group, which were used in the experiment one, the three and the second groups, and were randomly divided into the empty white group, the model group, the grabbing group, the acupuncture group and the western medicine group, which were used in the experiment two. The PTSD sleep disorder rat model was replicated by the compound stress method, and the rats in the western medicine group were treated with paroxetine hydrochloride in the western medicine group at the beginning of the model. The acupuncture group was treated with the acupuncture treatment of Baihui, Neiguan, Shenen, Tai Chung four acupoints with "Shugan Tiao Shen" needle method, and the grasping group was fixed with the same grasping method in the treatment group. In the first group, the brain electroencephalogram (EEG) electrode was required to be buried and recovered after the model. After the intervention, the rats were collected and analyzed according to the following methods. A pair of rats was sold at 8:00 to 20:00 EEG, and the diurnal 12h sleep latency, the awakening sleep cycle and the sleep phase were obtained through the EEG differentiation. In experiment two, the action potential was recorded in the hippocampal CA1 and CA3 region by body multichannel technique. The action potential distribution, discharge frequency, wave amplitude, peak to peak interval (ISI) and power spectral density (PSD) were calculated by software, and the corresponding atlas was plotted. Experimental three rats were perfused in the heart to prepare the tissue section of the hippocampus CA1, CA3 region, and observe the God with the transmission electron microscope. The results of the above data were compared, and the results of the 1. sleep EEG model group were compared with the operation group. Compared with the operation group, the latency of non rapid eye sleep (NREMs) and rapid eye sleep (REMs), the prolongation of the awakening period, the total sleep period, the shortened NREMs and REMs, at 8:00. 9:00,15:00 ~ 18:00 awakening period (total sleep period) prolonged (shortened), NREMs was significantly different (P0.05, P0.01) at 8:00 ~ 9:00,15:00 ~ 9:00,15:00 ~ (P0.05, P0.01), and no significant difference was found in the rest (P0.05). There was no significant difference (P0.05) between the grabbing group and the model group (P0.05). The NREMs incubation period, the total sleep period, the total sleep period, the prolongation of the NREMs and REM8, the awakening period, the period of the awakening from 8:00 to 16:00 to 16:00 (the total sleep period) shortened (the extension), and the NREMs was significantly different (P0.05, P0.01) at 1 0:00,11:00 to 13:00,14:00 to 13:00,14:00. There was no significant difference in the rest (P0.05). Compared with the gripping group, the NREMs latency, total sleep period, NREMs and REMs prolonged, the awakening period shortened, and the awakening period from 8:00 to 13:00,15:00 to 18:00 (the total sleep period) shortened (the total sleep period), and NREMs in 9:00,12:00 to 13:00,15:00 to REMs and REMs was 13. There were significant differences between 00,15:00 and 17:.00 (P0.05, P0.01), and the rest were not significantly different (P0.05). Compared with the western medicine group, the waking period (total sleep period) was longer (shorter) from 9:00 to 10:00 and shorter (longer) in the acupuncture group than in the western medicine group. There were significant differences (P0.05), and the rest were not significantly different (P0.05). Compared with the blank group, the spatial and temporal model group of.2. hippocampal neural coding was less than that in the blank group, CA1, the discharge of action potential was reduced, the frequency of discharge was shortened, the frequency band of the concentration distribution was reduced, and the frequency of the concentration distribution was reduced, and the radio waves were sparse, messy, and the waveform was narrowed, and the amplitude of the waveform decreased. The discharge interval sequence (ISI) was prolonged, PSD decreased and the concentration distribution of spectral power decreased significantly (P0.05, P0.01). There was no significant difference between the grabbing group and the model group (P0.05). Compared with the model group, the western medicine group and the grabbing group were compared with the grabbing group, CA1, CA3 area action potential distribution increased, the discharge frequency extended, the concentration distribution band increased, from paroxysmal to broken. Continuity; radio wave rules, neatly, wave amplitude increase, discharge interval sequence (ISI) shortening; PSD rise, the spectrum power concentrated distribution area moves up, there are significant differences (P0.05, P0.01).CA1 region width, but the CA3 area waveform width has no change. Compared with the grasping group, the acupuncture group increases the action potential in CAl, CA3 area, and the discharge frequency is prolonged. The concentration distribution band increased from paroxysmal state to intermittent; the radio wave rules, neatly, wave width, the amplitude of the waveform increased, the discharge interval sequence (ISI) shortened; the PSD increased, the spectral power concentrated distribution area moved up, there were significant differences (P0.05, P0.01). Compared with the western medicine group, the acupuncture group and the CA1, CA3 area action potential distribution and discharge frequency were compared. The distribution frequency and state of the discharge frequency, the shape of the discharge wave, the width of the amplitude of the CA1 region, the sequence of the discharge interval (ISI), the distribution of PSD and the spectral power are close, and there is no significant difference (P0.05), but the amplitude of the CA3 region in the CA3 region of the rats of the acupuncture group is wide, the amplitude of the average waveform is higher, and there is a significant difference (P0.05).3. hippocampal neurons. Compared with the blank group, the number of neurons in the microstructural operation group decreased, the nucleus was slightly irregular and the synaptic gap was not obvious. The cells were swollen, the electron density was low, the nucleus was irregular and the chromatin structure in the nucleus was loose, and the internal structure of the cytoplasm was empty or loose and the mitochondria swollen in the model group compared with the operation group. Swelling, partial mitochondrial membrane and ridge structure disappeared, rough endoplasmic reticulum dilated, synapses were not clear, structure open, and synaptic vesicles decreased. Compared with the model group, the grab group had no significant difference. Compared with the grabbing group, the number of neurons increased, the nucleus was round, and the chromatome was abundant; the CA1 area rough endoplasmic reticulum, ribosome increased; Synapses; Synapses The synaptic structure tended to be normal and the synaptic vesicles increased. Compared with the grabbing group, the number of neurons in the acupuncture group was increased, the structure was clear, the chromatin in the nucleus was uniform and the chromatin was abundant. In addition to the CA3 region, some mitochondria were slightly swelling, the organelle increased, the mitochondria structure was clear, the rough surface of the net stripe like distribution, the ribosome rich and the high levels were high. The synapses were common, the synapses were clear, the synapse structure tended to be normal, the synaptic vesicles increased and abundant. Compared with the western medicine group, the number of neurons in the CA1 area was more, the volume was larger, the mitochondria were round or rod-shaped, the structure was clear, the rough endoplasmic reticulum like distribution, the Golgi complex were common, the structure of the CA3 area was clear, the electron density was high, and the density was fine. The chromatin distribution in the nucleus is not regular, the chromatin distribution in the nucleus is basically uniform, the organelle is rich, the rough surface of the endoplasmic reticulum, the ribosome is rich, the Golgi complex is common, the synaptic vesicles are more abundant. The rest no obvious difference is found. Conclusion first, the compound stress method can cause abnormal changes of sleep electroencephalogram in rats, cause PTSD sleep disorder, and PTSD sleep. The abnormal changes in the spatio-temporal pattern of neural information coding in the hippocampal CA1 and CA3 region of the rat hippocampus may be an important central mechanism for the occurrence of PTSD sleep disorders. This change may be related to the morphological structure damage of the neurons in the brain. Second, the "Shugan Tiao Shen" needle method can obviously change the abnormal sleep brain electricity of the PTSD sleep disorder rats and promote sleep. The "Shugan Tiao Shen" needle method can restore the characteristics of the action potential distribution and regulate the spatio-temporal pattern of neural information coding in the CA1 and CA3 regions of the hippocampus, which may be an important central mechanism for the treatment of PTSD sleep disorders, and the corresponding neuron repair in the corresponding brain region may be the main cause of the reconstruction of the hippocampal power. Third, and Pa Rossi Dean hydrochloric acid. Compared with the treatment, the effect of "Shugan Tiao Shen" acupuncture therapy on abnormal sleep EEG, the influence of the spatio-temporal pattern of hippocampal neural coding and the regulation of neuron repair is better, and it will not cause somnolence and other side effects. It further illustrates that the intervention of "Shugan Tiao Shen Shen" needling can play a better therapeutic effect on PTSD sleep and sleep disorders. It is believed that "Shugan Tiao Shen" acupuncture method may promote the functional reconstruction of neural network by repairing hippocampal neuron structure, thereby playing a therapeutic effect on PTSD sleep disorders.
