Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of traditional Chinese medicine, in particular to a traditional Chinese medicine compound preparation and application thereof. Background Art
[0002] Acute bronchitis (AB) is an inflammation of the bronchial mucosa caused by infection with pathogens such as viruses or bacteria. It is a common respiratory disease in pediatrics, often secondary to upper respiratory tract infections and often an early manifestation of pneumonia. Because it often affects both the trachea and bronchi, it is also known as acute tracheobronchitis. Clinically, it is characterized by cough or increased bronchial secretions. Basic pathological changes include congestion and edema of the tracheobronchial mucosa, mucus plug formation, increased secretions, epithelial cell damage and desquamation, and inflammatory cell infiltration. In recent years, the global incidence of AB has increased significantly, becoming a serious global public health issue. Recurrent AB can develop into chronic bronchitis and even further into emphysema or cor pulmonale, placing a heavy psychological and economic burden on patients. According to the World Health Organization, acute respiratory infections, particularly AB, are the leading cause of death in children under five years of age (excluding newborns).
[0003] Research both domestically and internationally indicates that the underlying pathological mechanism of acute bronchitis is airway inflammation, with multiple cytokines and inflammatory mediators involved in the process. An imbalance in the Th1 / Th2 cell ratio is central to its pathogenesis, ultimately triggering an inflammatory response in the airways. Currently, Western medicine treatment for acute bronchitis in children focuses on infection control, primarily using antibiotics for inflammation, supplemented by antipyretic and cough suppressant medications. Reportedly, in 2012, the most common indication for antibiotics in children was bronchitis (AB), accounting for approximately 25.6%. Indiscriminate use of antibiotics can lead to the development of drug-resistant bacteria and serious consequences such as superinfection. In recent years, the role of traditional Chinese medicine in treating acute bronchitis in children has gained increasing attention. Traditional Chinese medicine possesses multiple antiviral, antipyretic, and anti-inflammatory properties, and can fundamentally enhance the body's immune system, demonstrating unique advantages in addressing the underlying cause of the disease, strengthening the body's resistance and expelling pathogenic factors, and treating both the symptoms and the root causes. Traditional Chinese medicine (TCM) compound prescriptions are a primary form of TCM medication. Based on the concept of syndrome differentiation and the principle of formulating according to the principles of monarch, minister, assistant, and envoy, they select appropriate TCM decoction pieces and combine them according to specific proportions. They embody the TCM theory of syndrome differentiation and treatment. TCM compound preparations have complex chemical compositions. The safety, efficacy, and stable, controllable quality of TCM materials and their products depend on quality control of authentic, sourced herbs to ensure the content of active ingredients within a specified range. This allows for the development of safe and effective TCM patent preparations for the treatment of acute bronchitis in children. Patent application number: 02129192.6, discloses a traditional Chinese medicine composition for treating colds and acute and chronic bronchitis and its preparation method. The traditional Chinese medicine composition of the present invention is made of 8-12 weight parts of antelope horn, 30-60 weight parts of flat fritillaria, 20-40 weight parts of rhubarb, 10-20 weight parts of scutellaria, 10-20 weight parts of greenstone, 15-30 weight parts of gypsum, 5-15 weight parts of artificial bezoar, and 20-40 weight parts of liquorice as raw materials. It has a good therapeutic effect on colds and acute and chronic bronchitis.
[0004] However, for traditional Chinese medicine (TCM) compound prescriptions, most raw materials are derived from natural products. The quality of these materials is highly variable due to factors such as origin, growth period, harvest season, and planting and processing techniques. Even when the raw materials comply with pharmacopoeia regulations, differences in active ingredients from different origins and batches can still lead to unstable ingredients and poor quality consistency in different batches of preparations. Therefore, prescriptions based solely on the weight of the medicinal materials cannot meet the production requirements of modern Chinese patent medicines, severely restricting the stability and controllability of TCM clinical efficacy and the reproducibility and acceptance of modern research results. Furthermore, the active ingredients in complex TCM compound prescriptions are unclear. Which major ingredients significantly influence the efficacy? What is the optimal range for their content? Reasonable control of the range of different active ingredients is necessary to ensure both the stability of TCM preparation quality and the reliability of its efficacy. This is a key issue restricting the development of modern TCM. Summary of the Invention

[0054] 2. Methods
[0055] 2.1 Effects of different batches of Chinese herbal medicine compositions on fever induced by dry yeast in rats
[0056] (1) Experimental methods
[0057] Male Sprague-Dawley rats, weighing 180-220 g, were acclimated for 7 days. The ambient temperature was maintained at 20-25°C during the experiment. Rectal temperature was measured daily at 10:00 AM for two consecutive days to allow the rats to acclimate to this procedure. The average of these two temperatures was used as the basal body temperature. Rats with a body temperature within the range of 37.0-38.6°C and a fluctuation of <0.5°C were selected for the experiment. Each rat was subcutaneously injected with 10 ml / kg of a 20% dry yeast suspension (preparation: 120 g of dry yeast was weighed, placed in a mortar, and gradually ground into a uniform suspension with distilled water. The final volume was adjusted to 600 mL, prepared immediately before use). Six hours after yeast suspension injection, the rats' body temperatures were measured. 170 rats with a body temperature rise between 1.0 and 2.2°C were selected and randomly divided into 17 groups based on body temperature. That is, (1) model group: distilled water, (2) TCM composition A-O group: 3.34g crude drug / kg; (3) control drug group: aspirin suspension, 0.20g / kg. Each group was gavaged with the corresponding solvent or drug, and rectal temperature was measured 1h, 2h, 3h, 4h, and 5h after administration, and the difference between body temperature at each time period after administration and basal body temperature was calculated.
[0058] (2) Experimental results
[0059] Compared with the model group, all treatment groups reduced the dry yeast-induced increase in rat body temperature at 2, 3, 4, and 5 hours after administration. The differences were more pronounced in the TCM composition groups B, C, D, H, I, J, and N compared with the model group. The results are shown in Table 3.

[0065] (1) Experimental methods
[0066] Male KM mice, weighing 18-22 g, were acclimated for 4 days. The ambient temperature was maintained at 20-25°C during the experiment. They were randomly divided into 17 groups, each with 10 mice: (1) model group: administered with distilled water; (2) Chinese medicine composition A-O groups: administered with 4.83 g crude drug / kg; and (3) positive group: administered with aspirin suspension at a dose of 0.20 g / kg. Mice in each group were gavaged once daily for 5 consecutive days. One hour after the last administration, 0.03 ml of xylene was applied to both sides of the right ear of the mouse, with the left ear serving as a control. One hour later, the mouse was sacrificed by cervical dislocation. An 8 mm punch was used to punch out round ear pieces from the same part of both ears of the mouse. The pieces were accurately weighed, and the difference between the weight of the right ear piece and the weight of the left ear piece was calculated as the degree of swelling.

[0073] (1) Experimental methods
[0074] ICR mice weighing 18-22 g, half male and half female, were pre-selected and the qualified mice were reared for 3 days (animals with a latent period of less than 1 min and more than 3 typical coughs within 1 min were classified as "coughing" sensitive animals; otherwise, they were eliminated as non-coughing animals). They were randomly divided into 17 groups, namely (1) model group: distilled water; (2) Chinese medicine composition A-O groups: 4.83 g crude drug / kg; (3) positive group: dioxetine hydrochloride suspension, 1.79 mg / kg. Each group of mice was gavage-administered once a day for 5 consecutive days. One hour after the last administration, the mice were placed in a glass bell jar of a multifunctional cough-inducing and wheezing instrument. 25-28% ammonia water was sprayed into the bell jar for 3 seconds. The cough latency and the number of coughs within 3 minutes of the mice were then observed and recorded. The cough standard was: abdominal muscle contraction, wide mouth opening, and sometimes coughing sound.
[0075] (2) Experimental results
[0076] Compared with the model group, each drug-treated group could significantly prolong the latent period of cough in mice and / or significantly reduce the number of coughs in mice. Among them, the Chinese medicine compositions B, C, D, F, I, K, and N showed significant differences compared with the model group. The results are shown in Table 5.

[0108] 1. Method
[0109] 1.1 Effects of different batches of Chinese herbal medicine compositions on fever induced by dry yeast in rats
[0110] (1) Experimental methods
[0111] Male SD rats, weighing 180-220g, were acclimated for 7 days. The ambient temperature was maintained at 20-25°C during the experiment. Rectal temperature was measured once daily at 10:00 AM for two consecutive days to allow the rats to acclimate to this procedure. The average of these two temperatures was used as the basal body temperature. Rats with a body temperature within the range of 37.0-38.6°C and a fluctuation of <0.5°C were selected for the experiment. Each rat was subcutaneously injected with 10ml / kg of a 20% dry yeast suspension (preparation method: 90g of dry yeast was weighed, placed in a mortar, and gradually ground into a uniform suspension with distilled water. The final volume was adjusted to 450ml and prepared immediately before use). Six hours after yeast suspension injection, the rats' body temperatures were measured. Ninety rats whose body temperatures rose between 1.0 and 2.2°C were selected and randomly divided into nine groups based on body temperature. The following were used: (1) model group: distilled water; (2) Chinese herbal medicine combination P-V group: 3.34 g crude drug / kg; (3) control group: 0.20 g / kg aspirin suspension. Each group was gavaged with the corresponding solvent or drug, and rectal temperature was measured 1, 2, 3, 4, and 5 hours after administration. The difference between body temperature at each time period and basal body temperature was calculated.
[0112] (2) Experimental results
[0113] Compared with the model group, all drug-administered groups were able to reduce the dry yeast-induced increase in rat body temperature after administration. The TCM composition R, S, and U groups showed significant differences compared with the model group at 2, 3, 4, and 5 hours. The results are shown in Table 8.

Mice in each group were gavaged once daily for 5 consecutive days. One hour after the last administration, 0.03 ml of xylene was applied to both sides of the right ear of the mouse, with the left ear serving as a control. One hour later, the mouse was killed by cervical dislocation. An 8 mm punch was used to punch out round ear pieces from the same part of both ears of the mouse. The two ears were accurately weighed, and the difference between the weight of the right ear piece and the weight of the left ear piece was calculated as the degree of swelling.
