Description

Technical Field

[0001] The present invention belongs to the technical field of traditional Chinese medicines, and in particular, relates to a traditional Chinese medicine composition for treating acute lung injury and a preparation and application thereof. Background Art

[0002] Acute Lung Injury (ALI) is a severe lung disease characterized by acute respiratory distress, hypoxemia, and damage to the alveolar-capillary barrier. Studies have shown that the incidence of ALI is about 10% to 15% in intensive care units, and the mortality rate is close to 40%. The main causes of ALI include infection, trauma, inhalation of toxic gases, etc. The disease progresses rapidly and is difficult to treat. Currently, the commonly used treatments in clinical practice are mainly supportive therapies, such as mechanical ventilation, fluid management, and antibiotic use. However, these methods can only temporarily relieve symptoms and fail to effectively inhibit inflammation or repair lung tissue damage. At the same time, drugs such as glucocorticoids may cause serious side effects such as immunosuppression, which limits their long-term use.

[0003] Qianjin Weijing Decoction comes from Qianjin Essential Prescriptions for Emergencies, and is a classic prescription for treating lung abscess. The lung abscess treated by this prescription is a type of lung disease caused by the combination of phlegm and blood stasis, and the accumulation of heat and toxicity, with cough, chest pain, fever, coughing up smelly turbid phlegm, and even pus and blood as the main symptoms. This prescription uses reed stem as the main medicine, which is sweet, cold and light in nature, and has the effects of clearing the lungs and resolving phlegm, expelling pus and relieving cough. It is an important medicine for treating lung abscess; coix seed is sweet, light and slightly cold, clears lung heat and discharges pus, and benefits the intestines and stomach and drains dampness; winter melon seeds clear heat and resolve phlegm, eliminate carbuncle and discharge pus, and are the ministerial medicines; peach kernels promote blood circulation and remove blood stasis to eliminate carbuncle, and are the adjuvants. The drugs in this prescription are exquisitely matched, and they have the effects of clearing heat and resolving phlegm, expelling blood stasis and discharging pus. Summary of the invention

[0019] The Chinese medicinal materials used by the inventors in the process of preparing the pharmaceutical composition of the present invention have the following sources: Phragmites rhizome, fresh or dried rhizome of Phragmites communis Trin. of the Gramineae family. Winter melon seeds, seeds of Benincasa hispida of the Cucurbitaceae family. Peach kernels, dried mature seeds of Prunus persica (L.) Batsch or Prunus davidiana (Carr.) Franch. of the Rosaceae family. Coix lachryma-jobi, dried mature seed kernel of Coixlacryma-jobi L.var.ma-yuen (Roman.) Stapf of the Gramineae family. Portulaca, dried aerial parts of Portulaca oleracea L of the Portulacaceae family. Patchouli, dried aerial parts of Pogostemoncablin (Blanco) Benth. of the Lamiaceae family.

[0020] Based on many years of clinical practice experience, the inventor believes that the six exogenous pathogens and the seven internal emotions can all become the pathogenic factors of this disease, but the deficiency of positive energy and the damage of qi, blood, yin and yang are all throughout this disease. In traditional Chinese medicine, ALI belongs to the categories of "asthma and collapse", "chest knot", "violent asthma", etc. Its pathogenesis is that the lung controls the qi mechanism, the exogenous pathogens invade the lungs, the qi mechanism is stagnant, the pathogenic heat is transmitted to the Yangming meridian, and the accumulation in the intestines is combined to cause heat and colon dryness; if it goes up, it will be asthma, if it is blocked in the middle, it will be full, the heat forces the blood to flow, the blood overflows the veins and causes blood stasis, the blood stasis and heat are combined, and the lungs are blocked, causing the lungs to lose their function of regulating water channels and water retention. Therefore, traditional Chinese medicine believes that the key to the pathogenesis of ALI lies in four aspects: heat, blood stasis, water (wetness), and deficiency. The Chinese medicine composition of the present invention contains six Chinese medicines in total. In the prescription, the root of reed is sweet, cold and light, good at clearing lung heat and opening the lung orifices, and is the main medicine. Winter melon seeds can clear away heat and resolve phlegm, promote dampness and promote urination, and cooperate with the main medicine to clear the lungs and relieve congestion; coix seed is sweet, mild and slightly cold, clears lung heat from above, promotes the intestines and stomach and removes dampness, so that the evil of damp heat is eliminated through urination, and is a ministerial medicine. Peach kernel can promote blood circulation and remove blood stasis, moisten dryness and lubricate the intestines, and is combined with winter melon seeds to eliminate the evil of phlegm and heat through defecation; purslane can clear away heat and detoxify, cool blood and stop bleeding, so peach kernel can promote blood circulation and stop bleeding; Patchouli can relieve the exterior and resolve dampness, and is a supporting medicine. The six medicines are used together to have the functions of clearing heat, removing blood stasis and promoting diuresis.

[0107] Experimental methods:

[0108] Mice were randomly divided into a normal group, a model group, a Chinese medicine combination group, and a disassembled prescription group (disassembled prescription 1, disassembled prescription 2, disassembled prescription 3, disassembled prescription 4, disassembled prescription 5, and disassembled prescription 6). There were 10 mice in each group. After one week of adaptive feeding, the Chinese medicine combination group and the literature prescription group were given Chinese medicine combination and disassembled prescription by gavage once a day, respectively; the normal group and the model group were gavaged with equal volumes of normal saline once a day. On the 7th day of gavage, 20 mg / kg of LPS was injected intraperitoneally to establish the model. Mice in the model group, the Chinese medicine combination group, and the disassembled prescription group were all given LPS intraperitoneal injection to establish the model. The normal group was given an intraperitoneal injection of normal saline. During the experiment, all mice were observed for symptoms of dyspnea, and the onset time was recorded. Mice were disposed of 24 hours after modeling, and blood was collected to separate serum for serological detection. IL-1β, TNF-α, and Hif-1α levels were detected according to the instructions of the ELISA kit.

[0109] Statistical methods:

[0110] All data were analyzed using SPSS 29.0 statistical software. After the variance homogeneity test, one-way analysis of variance was used for data from more than two groups. P < 0.05 indicated statistical significance.

[0111] Experimental results:

[0112] Table 5 shows that the inhibitory effect of the Chinese medicine combination on the symptoms of dyspnea, inflammatory factors, and hypoxia-inducible factors in mice is better than that of each decomposed prescription group; all mice in the model group had dyspnea. As can be seen from Table 5, compared with the model group, the dyspnea time of the Chinese medicine combination and each decomposed prescription group was significantly reduced (P<0.01), but the therapeutic effect of any decomposed prescription with one less medicine was not as good as that of the Chinese medicine combination, and there was a statistical difference (P<0.01). Compared with the normal group, the serum inflammatory factor IL-1β and hypoxia-inducible factor Hif-1α of mice in the model group were significantly increased (P<0.01). Compared with the model group, the inflammatory factors IL-1β and hypoxia-inducible factor Hif-1α in the serum of the Chinese medicine combination and each decomposed prescription group were significantly reduced (P<0.01), but the therapeutic effect of any decomposed prescription with one less medicine was not as good as that of the Chinese medicine combination, and there was a statistical difference (P<0.01).

[0116] Example 10 Comparative study of treatment with Chinese medicine combination and conventional western medicine alone

[0117] Study subjects

[0118] The patient went to the TCM Internal Medicine Clinic of Shuguang Hospital and was diagnosed with acute lung injury. He was in the recovery period and was also diagnosed with Qi and Yin deficiency by TCM diagnosis.

[0119] Western medicine diagnostic criteria:

[0120] The diagnostic criteria for acute lung injury (ALI) refer to the 2012 Berlin Definition (Acute respiratory distress syndrome: the Berlin Definition): lung imaging changes, PaO2 / FiO2≤300mmHg, and excluding pulmonary edema caused by heart failure and fluid overload. The onset time is within the past month.

[0121] TCM diagnostic criteria:

[0122] Refer to the chapter "Asthma" in the "Tenth Edition of the National TCM Colleges and Universities Planning Textbook for Internal Medicine". The main clinical manifestations are shortness of breath when moving, dyspnea, general fatigue, opening the mouth and raising the shoulders, twitching of the nostrils, inability to lie flat, tired expression, spontaneous sweating or night sweats, low fever, hot hands and feet, poor appetite, dry mouth and tongue, and red tongue with little coating. Inclusion criteria: (1) 18 years old ≤ age ≥ 80 years old; (2) meet the above-mentioned Western medicine and TCM diagnostic criteria; (3) the patient and his family agree and are willing to sign the informed consent form.

[0123] Exclusion criteria:

[0124] (1) Patients who are not in recovery or are in critical condition. (2) Patients with other serious systemic diseases, heart failure, severe liver and kidney dysfunction, etc. (3) Patients with abnormal consciousness or mental illness. (4) Patients with allergic constitution.

[0125] Research Methodology:

[0126] Patients in the recovery period of acute lung injury, and at the same time, TCM syndrome differentiation is Qi and Yin deficiency. A total of 60 cases were randomly divided into a Chinese medicine group and a control group, with 30 cases in each group. Conventional Western medicine treatment of acute lung injury refers to the "Guidelines for the Diagnosis and Treatment of Acute Lung Injury / Acute Respiratory Distress Syndrome (2006)". The control group was given conventional Western medicine treatment (including oxygen therapy, antibiotics, glucocorticoids, fluid management, etc.). The Chinese medicine group was treated with a Chinese medicine composition (30g of wax gourd seeds, 30g of reed root, 10g of peach kernel, 20g of coix seed, 30g of purslane, 9g of Patchouli) on the basis of conventional Western medicine treatment. The preparation method is the same as Example 3, 1 dose per day, orally after meals, 7 days as a course of treatment. The efficacy was observed after 7 treatments.

[0127] Efficacy criteria:

[0128] According to the TCM syndrome scoring scale of the "Clinical Disease Diagnosis Based on Cure and Improvement Standards" and the "Guidelines for Clinical Research of New Chinese Medicines", the scores of patients before and after medication were recorded. Calculation formula: efficacy rate = (total score before treatment - total score after treatment) / total score before treatment × 100. Cured: The patient has no obvious shortness of breath and fatigue when moving, and the oxygenation index is >300mHg; the TCM syndrome score is reduced by ≥90%; markedly effective: The patient has only slight shortness of breath and no obvious fatigue; 60%≤ TCM syndrome score reduction <90%; progress: The patient's shortness of breath when moving is relieved compared with before, but some symptoms still exist, 30%≤ TCM syndrome score reduction <60%; ineffective: The patient's shortness of breath and panting are roughly the same as before, but the relief is not obvious, there are often interruptions or obvious panting when speaking, and there are still symptoms such as mental fatigue, general fatigue, dry mouth, spontaneous sweating and night sweats; TCM syndrome score reduction <30%. Total effective rate = cure rate + markedly effective rate + improvement rate.

[0129] Observation of inflammation indicators:

[0130] The neutrophil ratio (NEUT%) and C-reactive protein (CRP) in the blood of the two groups of patients were detected at 7 days of treatment. Safety monitoring:

[0131] Observe the patient for any adverse reactions such as allergic reactions, diarrhea, vomiting, dizziness, etc.

[0132] Statistical analysis:

[0133] All data were processed using SPSS 29.0 statistical software. After the variance homogeneity test, the independent sample t test was used for the comparison between the groups before and after treatment, and the one-way analysis of variance was used for the comparison within the same group. The count data were expressed as the number of cases (%), and the categorical count data were expressed using Pearson χ 2 P<0.05 was considered statistically significant.

[0134] Research findings:

[0135] The general information of the patients was collected, and there was no significant difference in age, gender, and smoking history, and the two groups of patients were comparable. Table 6 shows the efficacy of the Chinese medicine composition on acute lung injury. The total effective rate of the Chinese medicine group can reach 96.7%, and the efficacy of the Chinese medicine group is better than that of the control group, and the difference is statistically significant (P<0.01). It shows that the Chinese medicine composition significantly relieves the symptoms of patients, and the total effective rate of combined treatment with the Chinese medicine composition is better than that of conventional Western medicine alone. Table 7 shows the effect of the Chinese medicine composition on inflammatory indicators in patients with acute lung injury. Compared with the control group, the neutrophil ratio and C-reactive protein of the Chinese medicine group were significantly reduced (P<0.01). It shows that the Chinese medicine composition can reduce inflammation in patients. Through safety monitoring, no adverse reactions occurred in the Chinese medicine group. It shows that the Chinese medicine composition has good safety, definite clinical efficacy, and important clinical value for acute lung injury.
