[0060] Table 1

[0061] The changes in the TCM syndrome scores of patients before and after treatment are as follows

[0062] After 8 weeks of treatment, the TCM syndrome scores of patients such as depression, insomnia, loss of appetite and palpitations were significantly reduced compared with those before treatment. The difference in scores before and after treatment is shown in Table 2.

[0063] Evaluation was performed before and after treatment to determine the changes in TCM syndrome scores in the two groups.

[0064]

[0065] Table 2

[0066] Observation indicators: TCM syndrome score: According to the TCM syndrome scoring standard in the "Principles of Clinical Research Guidelines for New Chinese Medicines" [8], the main symptoms are scored 0, 2, 4, and 6 points in order from none, mild, moderate, and severe. The scores before treatment and after two courses of treatment are calculated according to the "Standards for Diagnosis and Efficacy of TCM Diseases and Syndromes". The calculation formula is (pre-treatment score - post-treatment score) / pre-treatment score × 100%; the main symptoms include depression, insomnia, loss of appetite, and palpitations. (2) Depression status index: According to the HAMD scale, a 5-point scoring method of 0-4 is used, 0-4 points are: none, mild, moderate, severe, serious, etc. The scale items include 24 items such as depression, difficulty falling asleep, mental anxiety, systemic symptoms and sense of reduced ability. A score of less than 8 points is normal, 8-20 points are mild depression, 20-35 points are moderate depression, and more than 35 points are severe depression.

[0067] Comparison of HAMD scores of patients before and after treatment:

[0068] After 8 weeks of treatment, the patient's depression, difficulty falling asleep, mental anxiety, systemic symptoms and sense of reduced ability; HAMD scale scores were significantly lower than before treatment, see Table 3.

[0069]

[0070] Table 3

[0071] In summary: Clinical research results show that after taking it for 8 weeks, the main depressive symptoms of patients, including low mood, difficulty falling asleep, mental anxiety, and systemic symptoms and sense of reduced ability, have been significantly improved. These data fully demonstrate that this treatment plan has a significant alleviating effect on liver depression and qi stagnation syndrome. The core of this treatment plan is to soothe the liver and relieve depression, nourish blood and calm the mind, and harmonize the liver and kidney. It specifically targets various symptoms caused by liver qi stagnation, liver and kidney deficiency, and restlessness. It is particularly suitable for diseases that show the characteristics of bad mood and liver and kidney deficiency, and has a significant improvement effect.

[0072] Animal research data

[0073] A total of 24 Sprague-Dawley (SD) male rats (250g±20g) were divided into four groups, with 6 rats in each group: normal group (Control group), model group (CUMS group), Jinsi Ningshen Tea group (CUMS+JSNSC1.2g / kg), and control drug group (fluoxetine CUMS+Ful8.58mg / kg). All rats were adaptively fed for 7 days, and then the rats in the CUMS group, Jinsi Ningshen Tea group, and fluoxetine group were subjected to CUMS modeling for 28 days. During the modeling period, the rats were given different stimuli every day, and the same stimulation appeared discontinuously and irregularly, including sucrose preference test, open field test, and forced swimming for 5 minutes.

[0074] a. Sucrose Preference Test (SPT)

[0075] The sucrose preference test is an experiment used to measure the degree of rats' preference for sucrose. Rodents have a strong desire for sweets, and rats that are depressed due to chronic stress have a reduced preference for sucrose. Therefore, testing the preference of rats for sucrose solutions has become an important means of assessing the degree of depression in rats. Figure 1 As shown in the figure, the experiment includes two stages: adaptation and test. During the adaptation period, two bottles of 1% (W / V) sucrose solution were placed in each cage for 24 hours. After the adaptation, one of the bottles of sucrose solution was replaced with a pure water solution for 24 hours. During this period, the positions of the two bottles should be swapped regularly to eliminate the position preference that the rats may have during the experiment. After that, a baseline measurement was performed. The rats were fasted and deprived of water for 12 hours before the test. During the formal experiment, a bottle of 1% sucrose aqueous solution and a bottle of pure water solution were placed in each cage respectively. The consumption of sucrose solution and water solution of each rat within 1 hour was observed and recorded. The sucrose preference index was calculated as sugar water consumption / (sugar water consumption + pure water consumption))×100%. The experiment was conducted once before the modeling, after the modeling, and after the drug administration.

[0076] SFT experimental results: The sucrose preference index of rats was tested at three time points: the beginning of modeling, the end of modeling, and the end of drug administration. Figure 1 As shown in the results, it can be clearly seen that at the beginning of the experiment, there was no significant difference in the degree of sucrose preference among the four groups of rats. After 28 days of modeling, the sucrose preference index of the rats in the model group decreased significantly, and both showed significant differences from the normal group of rats. After 12 days of administration, the sucrose preference index of the rats in the Jinsi Ningshen Tea group and the fluoxetine group returned to normal, and there was no significant difference from the Control, while the sucrose preference index of the rats in the model group was still low.

[0077] b. Open field test (OFT)

[0078] The open field test is a common animal behavior experiment that can be used to detect the spontaneous activity and exploratory behavior of rats. It is often used to measure the autonomous behavior of experimental animals in a new environment. Normal rats will explore the surrounding environment due to fear in a new environment, while rats in a depressed or anxious state will have less exploratory behavior and will mostly stay in a corner. Therefore, the degree of depression can be evaluated by observing the movement state of the rats. Figure 2 As shown in the figure, the rat open field experiment should be carried out in an experimental box with a specification of (length * width * height) 100cm * 100cm * 40cm. Before each experiment, the experimental box should be cleaned and disinfected to eliminate the effects of residual feces, urine and odor from the previous experimental animals. During the experiment, the operator should gently take the rat out of the breeding cage, turn the rat's back to the operator, and quickly place the rat in a fixed position in the experimental box. The observer should leave immediately, turn on the camera and analysis software, count for 5 minutes, count the total horizontal movement distance of the rat during this time period, observe the number of times it stands upright, and count the number of feces. It should be noted that the experimental rats have a circadian rhythm. In order to avoid the influence of the circadian rhythm, the experiment should be carried out in the same time period as much as possible. This experiment conducted open field experiments after the modeling and after the drug administration to detect the rat's movement behavior and evaluate its depressive state.

[0079] OFT experimental results: After the modeling and drug administration, the four groups of rats were subjected to open field tests to observe and record the total distance of the rats' open field movement. Figure 1 As shown in the data, after the modeling, there were significant differences in the total movement distance between the rats in the Control group and the other two groups (P < 0.05). The Control group was active in the open field and had a long movement distance, while the behavioral mobility of the rats after CUMS modeling was significantly reduced, and the total movement distance in the open field was significantly decreased. The total movement distance of the rats in the Jinsi Ningshen Tea group and the fluoxetine group in the open field increased.

[0080] c. Forced Swimming Test (FST)

[0081] The forced swim test is a method used to screen and evaluate antidepressants. Figure 3 As shown, in this experiment, rats were placed in a cylindrical transparent bucket with a diameter of 20 cm, a height of 40 cm, and a water depth of about 30 cm. The water temperature was controlled at 23-25°C. The time was 5 minutes. The swimming behavior of the rats in the water, such as climbing behavior and immobility, was observed, and the total immobility time of the rats in the water was recorded. This experiment was carried out after the modeling and after the drug administration to evaluate the depressive state of the experimental rats.

[0082] FST experimental results: After the modeling and drug administration, the four groups of rats were subjected to forced swimming tests, and their immobility time in water was recorded. Figure 3 As shown in the data, after the modeling was completed, the rats in the Control group moved for a longer time in the water, while the rats in the drug-treated group and the model group basically did not move in the water, and there were significant differences between them and the rats in the Control group (P < 0.05). After completing the 12-day drug administration, the immobility time of the rats in the Golden Silk Ningshen Tea group and the Fluoxetine group was significantly lower than that in the Model group, and there was no significant difference between them and the rats in the Control group, while the immobility time of the rats in the Model group was still significantly higher than that in the other two groups.

[0083] In summary: Hypericum perforatum is used as the main drug in the prescription because it has the effects of soothing the liver and relieving depression, clearing away heat and removing dampness, and reducing swelling and promoting lactation. Hypericum perforatum extract has a significant antidepressant effect, can regulate neurotransmitters, and improve depressive symptoms; Ziziphus jujuba seeds are used as the assistant drugs to assist the main drugs in strengthening the treatment of the main disease or main syndrome; Ziziphus jujuba seeds have the effects of nourishing the heart and calming the mind, replenishing liver qi, and strengthening tendons and bones, and have a good effect on improving symptoms such as insomnia and anxiety caused by liver depression; Longan pulp is used as the adjuvant drug in the prescription, which has the effects of nourishing the heart and spleen, nourishing blood and calming the mind, and it can assist Hypericum perforatum Peach and Chinese jujube kernel enhance the effect of nourishing the heart and calming the mind, and at the same time have a certain improvement effect on loss of appetite and fatigue caused by liver depression and spleen deficiency; as an adjuvant, Cornus officinalis has the effect of nourishing the liver and kidney, astringing and consolidating, and in the prescription, it assists Hypericum perforatum in soothing the liver and relieving depression, and at the same time has a certain auxiliary therapeutic effect on liver and kidney deficiency; as an adjuvant, jujube has the effect of nourishing the middle and replenishing qi, nourishing blood and calming the mind, and plays a role in harmonizing the various drugs in the prescription, making the medicinal properties more mild, and at the same time enhancing the overall efficacy of the prescription, and has a certain regulating effect on spleen and stomach disharmony caused by liver depression;

[0084] The results of clinical experiments and animal experiments can show that the drink of the present invention has the effects of soothing the liver and relieving depression, calming the nerves, and effectively relieving the patient's depression. The effect is equivalent to that of fluoxetine. Clinical experience has confirmed that the use of fluoxetine can cause common adverse reactions such as insomnia, nausea, irritability, headache, motor anxiety, mental tension, tremor, etc., which often occur in the early stage of medication. The present invention was used for eight weeks without any adverse reactions being observed. The efficacy is similar to that of fluoxetine, and the safety is better.
