Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of traditional Chinese medicine, and particularly relates to a traditional Chinese medicine composition for nourishing the lung and benefiting qi as well as a preparation method and application thereof. BACKGROUND

[0002] In the modern environment, the population with lung qi deficiency gradually increases due to air pollution, second-hand smoke, high incidence of respiratory diseases and other factors. Common symptoms caused by lung qi deficiency and dry heat damaging fluid include cough, blood in sputum, dry mouth and dry tongue, etc. Among them, due to the influence of dry heat on the lung, the airway is stimulated, causing cough, which mainly manifests as shortness of breath, dry throat, and dry cough or little sputum, which may be accompanied by sore throat or burning sensation. Due to the invasion of dry heat on the lung, the airway is not smooth and sputum is difficult to discharge. When dry heat damages the lung collaterals, it may also cause blood vessels to rupture and bleed, at which time the blood and respiratory secretions mix to form sputum, resulting in the symptom of blood in sputum.

[0003] At present, the curative effect of traditional Chinese medicine for treating lung qi deficiency and dry heat damaging fluid still needs to be improved, and most of the existing lung-nourishing prescriptions focus on single tonification or heat-clearing, lacking a synergistic formula that takes both clearing and tonifying into account. In addition, although Dendrobium huoshuiense flowers, loquat leaves and other medicinal materials are recorded in ancient books, there is a lack of optimized compatibility and standardized extraction process according to modern physical characteristics.

[0042] To verify the efficacy of a lung-yangqi traditional Chinese medicine composition in the application, zebra fish anti-viral pneumonia detection experiments are carried out, as follows: (1), detection principle The swim bladder of zebra fish is similar to the alveoli of mammals in organ evolution, tissue structure and biology.

[0043] Viral pneumonia: A zebrafish viral pneumonia model was established by injecting poly(i:c) protein. The double-stranded RNA structure of poly(i:c) is very similar to that of viruses or double-stranded RNA formed during viral replication. Therefore, poly(i:c), similar to some viruses, has a strong interferon-inducing effect. Using transgenic neutrophil-positive green fluorescent zebrafish and transgenic macrophage-positive green fluorescent zebrafish, neutrophils and macrophages in zebrafish can be directly observed under a fluorescence microscope, and the leakage of macrophages and neutrophils into blood vessels is recorded at different time points. A zebrafish viral pneumonia model was established based on the significant increase of neutrophils in the swim bladder.

[0044] (2) Experimental instruments and reagents Stereoscopic microscope (SZX7, Olympus, Japan), poly(i:c) (CAS: 24939-03-5).

[0045] (3) Testing process Zebrafish were divided into four groups: a blank control group, a model control group, an anti-inflammatory drug group, and groups from Examples 1, 2, 3, 4, and 5. The model control group, the anti-inflammatory drug group, and groups from Examples 1-5 were all injected with the same amount of LPS to establish a bacterial pneumonia model. The anti-inflammatory drug group received an anti-pneumonia anti-inflammatory drug such as indomethacin concurrently with the LPS injection. Groups from Examples 1-5 received the oral formulations prepared in the respective examples concurrently with the LPS injection. After a period of administration, the number of neutrophils and macrophages in the zebrafish was measured under a fluorescence microscope.

[0046] (4) Detection system and sample size Experimental system: Wild AB strain zebrafish Zebrafish age: 5 days after fertilization Sample size per group: 30 samples per well, 1 well per group (5) Data processing methods SPSS 26 software was used for analysis, and GraphPad Prism 8 was used for plotting. Data statistics are expressed as mean ± standard deviation. Experimental results were tested for normality using SPSS software. If the data conformed to a normal distribution, the significance was determined using a t-parametric test or analysis of variance (ANOVA). If the data did not conform to a normal distribution, a non-parametric test was used (a p-value < 0.05 indicates statistical significance). (6) Judgment basis Based on the fact that the experiment met the validity requirements, the number of neutrophils in the model control group was significantly increased compared with the blank control group (P<0.05), which means that the modeling was successful.

[0047] Compared with the model control group, the number of neutrophils in the example 1-5 groups was significantly reduced (P<0.05), indicating that the oral preparation corresponding to the example 1-5 group has the efficacy of anti-viral pneumonia.

[0048] (7), result analysis The efficacy of anti-viral pneumonia and the number of neutrophils are shown in Table 1, Figure 1 and Table 2.

[0049] Table 1 Anti-viral pneumonia efficacy table Detection concentration (mg / L) P value Detection result Example 1 group 1000 P＜0.05 Effective Example 2 group 1000 P＜0.05 Effective Example 3 group 1000 P＜0.05 Effective Example 4 group 1000 P＜0.05 Effective Example 5 group 1000 P＜0.05 Effective Table 2 Neutrophil number result table Blank control group Model control group Positive control group Example 1 group Example 2 group Example 3 group Example 4 group Example 5 group 24.40±3.38 44.10±4.74 31.5±3.69 31.2±3.24 29.1±3.59 29.8±3.46 30.7±3.34 30.1±3.75 Through the anti-viral pneumonia detection experiment, it can be seen that, under the experimental conditions, compared with the model control group, the number of neutrophils in the example 1-5 groups was significantly reduced (P<0.05), indicating that the oral preparation corresponding to the example 1-5 group has the efficacy of anti-viral pneumonia.
