Description

Traditional Chinese medicine composition for preventing and treating anxiety disorder and preparation method and application thereof
Technical Field
The invention belongs to the technical field of traditional Chinese medicines, and in particular relates to a traditional Chinese medicine composition for preventing and treating anxiety disorder, and a preparation method and application thereof.
Background
Anxiety disorder (anxiety), also known as anxiety neurosis, is one of the most common of the major classes of disorders, neurosis, and is characterized by an anxiety emotional experience. Chronic anxiety, i.e. generalized anxiety (generalized anxiety) and acute anxiety, also known as panic attacks (PANIC ATTACK), can be divided into two forms. The main manifestations are: there is no stress concern of clear and objective subjects, and restlessness is often accompanied by sleep disorder and autonomic nerve dysfunction symptoms such as dizziness, palpitation, dyspnea, dry mouth, hand tremble, sweating, frequent urination, urgent urination, tremor, and restlessness. The anxiety is not caused by a real threat or the tension is very disproportionate to reality.
The main etiology of anxiety is in several ways, firstly, the risk of anxiety is higher in people with family history than in general people. Secondly, it was found that gamma-aminobutyric acid is one of the bases of the pathogenesis, and it is also possibly involved in the hyperfunction of the norepinephrine system, abnormality of the 5-tryptamine system, and the like. Furthermore, the intra-cerebral emotional control loop is composed of forehead leaves, amygdala, hippocampus, hypothalamus, etc., and abnormal structure, function or association of these regions may cause emotional control disorders, which form the pathological structural basis of anxiety disorders. Psychological factors also play an important role in the development of anxiety disorders, such as generalized anxiety disorder due to unresolved conscious conflicts, information processing duration, etc.; social anxiety disorders are due to excessive patient attention and evaluation by others who are in mind, and may also be associated with some negative experience before adulthood; specific phobia may be associated with fear objects and traumatic experiences.
Traditional Chinese medicine has unique advantages in improving symptoms of anxiety patients, and is a current research hotspot. Traditional Chinese medicine considers that liver depression and qi stagnation and spleen deficiency malnutrition are main reasons for anxiety disorder. Liver depression, anxiety, emotional depression and anxiety lead to liver failure and diarrhea, qi stagnation, unfavorable channels and collaterals, fullness and distention and pain in chest and hypochondrium or lower abdomen, emotional depression and frequent sighing. Long-term anxiety, poor mood, stasis and impairment of spleen, insufficient qi and blood circulation and transformation of spleen deficiency, no nourishment of liver blood, and insufficient liver blood is not easy to be smooth. Therefore, the principle of soothing liver, relieving depression, strengthening spleen and promoting qi circulation is developed in clinic. However, in clinical practice, it is found that the therapeutic effect of the traditional Chinese medicine composition designed by purely using the therapeutic method of soothing liver-qi stagnation and strengthening spleen to promote qi circulation is not very ideal. For example, the traditional Chinese medicine classical prescription cassia twig decoction can strengthen yang and promote qi circulation and harmonize ying and wei, but has no liver soothing and qi regulating effects in the process of treating anxiety; the four adverse qi dispersing, liver soothing, qi regulating and mind smoothing effects can not be achieved, but yin and yang can not be harmonized, so that the best effect of treating anxiety disorder can not be achieved.
In view of the above, the classical ancient prescription needs to be deeply excavated by combining the pathogenesis of anxiety disorder, and a safer and more effective novel traditional Chinese medicine composition for preventing and treating anxiety disorder is further developed.

Anxiety disorder belongs to the category of traditional Chinese medical mental diseases, and is similar to depression, mania, lily disease and other diseases. The pathogenesis of the disease is mainly emotional internal injury, liver and gall are lost and dredged, qi stagnation and unsmooth blood circulation are caused; the spleen stores the mind and is one of the emotional activities of the five zang organs, namely the spleen. Anxiety and anxiety can damage the spleen, cause deficiency of qi and blood, imbalance of yin and yang, yin failing to astringe yang, yang failing to enter yin, yang qi failing to warm the mind, and anxiety can also result. As described in the background art, the traditional Chinese medicine classic formula cassia twig decoction can strengthen yang and promote qi circulation and harmonize ying and wei, but has no liver soothing and qi regulating effects; the four-function dispersing stagnated liver qi and smoothing the mind, but can not harmonize yin and yang, and the two formulas can not achieve the best effect of treating anxiety disorder by singly using the four-function dispersing stagnated liver qi and smoothing the flow of qi, and the two formulas can achieve the effects of soothing liver, regulating spleen, nourishing blood, promoting blood circulation and harmonizing yin and yang by modifying and cutting the two formulas through clinical experience.
Therefore, the method takes soothing liver and relieving depression, regulating qi and blood as an legislation, wherein cassia twig has the effects of tonifying yang and qi, red paeony root has the effects of nourishing blood and activating blood, and costustoot has the effects of strengthening spleen and activating qi and activating blood, and harmonizing yin and yang; radix Platycodi, with pungent and dispersed nature, has effects of dispersing lung qi, increasing Tilly water, and ascending medicine; bitter orange can reduce bitter taste, reduce qi and relieve distention, and relieve chest stuffiness and promote qi circulation, and the two medicines are compatible, one ascending and one descending and one diffusing and one dispersing, so as to achieve the effects of promoting qi circulation and dispersing stagnation; licorice root, radix Glycyrrhizae Praeparata regulates the drugs.

110 SPF-class SD male rats of 6-8 weeks old, body weight (160+ -10 g), purchased from Peking Violet laboratory animal technologies Co., ltd., animal production license number: SCXK (Beijing) 2016-0011. The animals were bred in Beijing, the animal experiment center of the company of the Uygur medicine science and technology, license number: SYXK (Beijing) 2022-0007, temperature (22+ -2deg.C), humidity (50+ -10)%, and 12h light/dark period. The animals are free to ingest and drink water.
2. Modeling, grouping and administration of animals
Adaptive feeding was performed for 3 days, and a rat anxiety model was established using 3 week empty bottle stress. The specific operation is as follows: training with regular feeding for 7 days, 9:00-9:10 and 21:00-21:10, animals are drunk for 10 minutes, and the water bottle is removed for water inhibition in the rest time. On day 21 of 8: 00-21:10 start the stress experiment, and the uncertain empty bottle stimulation was given according to the experimental procedure for the above 2 time periods, the administration of the stimulation was irregular, and maintained 1 or 2 times per day for 21 days.
SD rats were randomly divided into 10 groups after molding: example 1 group, example 2 group, comparative example 1 group, comparative example 2 group, comparative example 3 group, comparative example 4 group, comparative example 5 group, comparative example 6 group, model control group, positive control group; 10 untreated SD rats were also used as normal control groups. Example 1, example 2, comparative example 1, comparative example 2, comparative example 3, comparative example 4, comparative example 5, and comparative example 6 were administered with the concentrates prepared in the "preparation example" section described above, and the amount of the lavage was 1.6 mL/day to ensure consistency between the groups.
The control group and the model group were given 1.6 mL/day of physiological saline for gastric lavage. The stomach was irrigated 1 time a day for 21 consecutive days. The administration dosage is converted into the gastric lavage administration dosage of the rat according to the clinical recommended dosage of the daily oral administration of the adult of 70 kg and the body surface area conversion coefficient of the adult and the rat. The method of dosing can be found, for example, in Xu Shuyun, pharmaceutical Experimental methodologies, anhui province, anhui university of medical science, 2002-01-01; zhao Wei, sun Guozhi. Conversion of dosage between different experimental animals [ J ]. Animal husbandry and veterinary science and technology information, 2010 (05): 52-53.
3. Tissue specimen collection
After the last administration, the patients are fasted and not forbidden for 12 hours. 10% chloral hydrate was anesthetized by intraperitoneal injection at 4 mL/kg. The supine position is fixed on an operating table. The abdomen skin is clamped by a left hand-held pick-up, a small opening is cut under the xiphoid process by a right hand-held scissors, the xiphoid process is clamped by a hemostatic forceps to lift up, ribs are cut up to the lower collar at the positions of 2cm on two sides of the xiphoid process, the chest is turned up, and the heart is exposed. A perfusion needle was inserted from the apex of the heart into the ascending aorta and clamped with a hemostat. The right auricle was cut. The hemostatic forceps close the abdominal aorta. Normal saline was withdrawn through the needle tube and injected into the heart through the perfusion needle until the two forelimbs and the two lungs of the rat became white (about 100 mL). The perfusion needle is connected with a paraformaldehyde infusion bottle arranged at the high position, and the perfusion is continued under the action of gravity. When the anterior limb and the neck of the rat are stiff, the fixing effect is good, and the perfused brain tissue is white and hard. Cutting off the head between the rear and cervical vertebrae, cutting off the scalp along the middle of the frequency top to remove soft tissues, gradually removing the parietal bone from the occipital bone macropore by using hemostatic forceps, fully exposing the brain, cutting off the brain nerve, and taking out the whole brain. General observations were made to dissect structures such as hippocampus, striatum, etc. Or placing the extracted brain in 30% sucrose buffer solution, and preserving in a refrigerator at 4deg.C to make frozen slices.
4. Effect index inspection
(1) Evaluation of anxiety behavior in rats by elevated plus maze experiment
The elevated plus maze experiment is developed on the basis of an elevated Y-shaped maze. The overhead cross maze consists of two open arms and two closed arms, wherein the two open arms and the two closed arms are crossed, the joint part is a central area, and the height of the joint part is a certain height from the ground. The principle is that the open-arm rats facing new things can generate curiosity to explore, and have darkish nature (closed arms), and conflict behaviors of exploration and avoidance occur between the two, so that anxiety psychology is generated. The height of the whole maze from the ground is equivalent to the psychological that the human beings stand on the cliff side, and fear and anxiety of animals are easily caused. Anxiety behavior of rats can be evaluated by comparing the residence time and number of rats in the open and closed arms.
(2) Evaluation of anxiety behavior in rats in open field experiments
The open FIELD TEST analysis system is used for observing and researching various behaviors of experimental animals after neuropsychiatric changes and the experimental animals enter the open environment, such as fear of the animals to the new open environment and activities mainly in peripheral areas and less activities in central areas, but the exploratory characteristics of the animals promote the animals to generate the motivation of the animals to move in the central areas, and the anxiety psychology generated by the activities can be observed. The experimental animals were placed rapidly in the central region of the experimental box and immediately left. Animal behavioural analysis software was turned on to automatically record the animal's activity in the box, usually 15 minutes. Total distance, speed and movement time were recorded to evaluate anxiety behavior in rats.
