Description

Technical Field

[0001] The present invention belongs to the technical field of traditional Chinese medicine, and particularly relates to a traditional Chinese medicine composition and application for preventing or treating hyperuricemia. Background Art

[0002] Hyperuricemia (HUA) is a chronic metabolic disease caused by impaired purine metabolism. In recent years, with improved living standards, the prevalence of HUA has steadily increased, becoming the fourth most common disease after hypertension, hyperlipidemia, and hyperglycemia, posing a serious threat to human health. HUA harms multiple body systems, most commonly affecting joints, leading to acute and chronic gouty arthritis, tophi, and joint deformities. Uric acid crystals can form urinary stones, disrupting renal tubular function and causing uric acid nephropathy, and in severe cases, renal failure. HUA can affect endothelial metabolism, exacerbating atherosclerosis and inducing coronary heart disease. HUA is an independent risk factor for vascular dementia and cognitive decline. It can also exacerbate diabetes and its chronic complications. Therefore, the timely and appropriate use of urate-lowering medications is essential to reduce uric acid deposition, mitigate gout attacks, alleviate cardiac damage, and minimize the risk of other complications.

[0003] Current treatment options primarily include drugs that inhibit uric acid synthesis, primarily allopurinol and febuxostat. These drugs can rapidly reduce the source of uric acid, but they are associated with adverse reactions such as gastrointestinal symptoms, rashes, liver damage, bone marrow suppression, skeletal muscle and connective tissue symptoms, and potentially fatal hypersensitivity reactions. Drugs that increase uric acid excretion, primarily benzbromarone and probenecid, should be used with caution in patients with urinary tract stones, hepatic and renal insufficiency, gastrointestinal ulcers, the elderly, and children. These drugs present significant clinical inconsistencies. Medication compliance in HUA, particularly in patients with asymptomatic HUA, is extremely low, which reduces the effectiveness of drug treatment. Urate oxidase analogs, primarily including purikaxib and rasburicase, are biologics that catalyze the conversion of slightly water-soluble uric acid to the highly water-soluble allantoin. Among them, Prekysib is a pegylated urate oxidase that can effectively lower serum uric acid, reduce uric acid crystal deposition, and promote the dissolution of tophi. However, its high price, short half-life, immunogenicity, and susceptibility to hypersensitivity reactions have resulted in suboptimal treatment outcomes in 40% of subjects. While these drugs have demonstrated some effectiveness in the treatment of HUA, real-world studies have found that HUA patients face numerous clinical limitations, including poor medication compliance (only 36.8% of patients have good compliance) and rebound serum uric acid levels after discontinuation, due to the combined effects of drug side effects and the insidious nature of HUA symptoms. Therefore, finding safe and effective drugs for the prevention and treatment of hyperuricemia is an urgent issue.

[0004] While Traditional Chinese Medicine (TCM) doesn't have names for conditions like "hyperuricemia" or "gout," gout can be categorized as "gout," "heat arthralgia," or "white tiger and calamity" based on its etiology, pathogenesis, and clinical manifestations. Treatment primarily focuses on clearing heat and dampness, and tonifying the kidneys and spleen. Hyperuricemia has a complex pathogenesis, and TCM offers significant advantages in treating this condition. Herbs and their compound formulas, which combine medicinal properties with food and are highly safe, offer multiple ingredients and procedures, making them particularly suitable for the prevention and treatment of this complex, lifestyle-related condition. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a new option for treating patients with hyperuricemia.

[0006] The technical solution of the present invention is a traditional Chinese medicine composition for preventing or treating hyperuricemia and kidney damage, comprising the following ingredients: extracts of thistle, gardenia, bamboo leaves, Chinese angelica, lily, corn silk, broccoli seed, and eucommia leaf. Hyperuricemia is caused by inadequate endowment, an irregular diet, invasion of external pathogens such as dampness and heat, or the mutual obstruction of phlegm and blood stasis, which blocks the meridians and joints, leading to poor circulation of qi and blood. Treatment should be based on clearing heat and dampness, cooling blood, activating blood circulation, and tonifying the kidneys. In the formula, thistle is sweet and cool, entering the blood, and is good at clearing heat and cooling blood, as well as promoting diuresis and relieving stranguria. Gardenia, bamboo leaves, and corn silk clear heat and purge fire, promoting diuresis and relieving stranguria. Lily nourishes the heart and moistens the lungs, replenishes yin and clears heat, and prevents other herbs from clearing heat and damaging yin. Broccoli seed extract lowers qi and resolves phlegm. Eucommia leaf tonifies the liver and kidneys, strengthening the tendons and bones. Chinese angelica nourishes and harmonizes blood, guiding blood back to the meridians, and preventing other herbs from causing cold and stagnant blood. Taken together, these herbs form a formula that clears heat and dampness, reduces acid and protects the kidneys, and cools blood and activates blood circulation. The Chinese medicinal ingredients in the prescription contain chemical components such as cyclopentane ether terpenes, flavonoids, and triterpenes, which have anti-inflammatory, antioxidant, kidney and liver protection effects, and can simultaneously inhibit uric acid synthesis, lower blood uric acid levels, promote uric acid excretion, inhibit inflammation, and improve liver and kidney damage. It is effective in preventing or treating hyperuricemia and kidney damage.

[0007] The weight ratio of each component is: 3 to 30 parts of chicory, 1 to 20 parts of gardenia, 1 to 20 parts of bamboo leaves, 3 to 20 parts of angelica, 3 to 30 parts of lily, 1 to 20 parts of corn silk, 0.1 to 20 parts of broccoli seed extract and 1 to 30 parts of eucommia leaves.

[0009] The present invention also provides a preparation method of the traditional Chinese medicine composition, comprising the following steps: adding water to thistle, gardenia, bamboo leaves, angelica, lily, corn silk, and eucommia leaves, heating and refluxing extraction twice, filtering, combining the extracts, drying and crushing, and mixing with broccoli seed extract for standby use.

[0010] Furthermore, during the extraction process, the mass-to-volume ratio of the material to the liquid (g / mL) is 1:3 to 1:20.

[0011] Preferably, the mass-to-volume ratio of the feed to the liquid (g / mL) is 1:10.

[0012] Specifically, each extraction time is 1 to 3 hours.

[0013] Preferably, each extraction time is 1 hour.

[0014] The present invention also provides a traditional Chinese medicine composition obtained by the above preparation method.

[0015] The present invention also provides use of the above-mentioned traditional Chinese medicine composition in preparing a medicine for treating or preventing hyperuricemia.

[0016] The present invention also provides the use of the above-mentioned traditional Chinese medicine composition in preparing a medicine for treating or preventing hyperuricemia kidney damage.

Filter, combine the extracts, dry and grind, add the broccoli seed extract, mix thoroughly, and set aside.

[0036] Example 2 Application of the Chinese medicine composition of the present invention

[0037] The mice were divided into blank control group (Control), model group (Model), allopurinol group (AP, 10 mg / kg / d), low-dose compound group (FL, 5.3 g / kg / d), and high-dose compound group (FH, 10.6 g / kg / d) according to their body weight using a random number table method, with 6 mice in each group.

[0038] 7-8 week old male KM mice were fed with a normal diet and given normal drinking water. After one week of adaptive feeding, mice in the control group were gavaged with 0.5% CMC-Na (0.1 mL / 10 g) and intraperitoneally injected with PBS (0.1 mL / 10 g) daily. The remaining groups were given intraperitoneally injected with potassium oxonate (200 mg / kg / d) and gavaged with hypoxanthine (500 mg / kg / d). At the same time, the allopurinol group was gavaged with allopurinol (10 mg / kg / d). The FL and FH groups were given 5.3 g / kg / d and 10.6 g / kg / d of the compound extract (the Chinese medicine composition prepared in Example 1) at a dosage of 0.1 mL / 10 g for 21 days. After 21 days, the mice were placed in metabolic cages to collect urine for 24 hours. All groups were fasted for 24 hours but not water, anesthetized with isoflurane, and blood was collected by enucleation. After blood was collected, the mouse heart was perfused with 30 mL of normal saline. After perfusion, the kidneys and liver were removed in sequence.

[0039] Indicator Assays: Serum uric acid and liver XOD enzyme levels were measured according to the instructions of the uric acid and XOD enzyme assay kits. Creatinine, urea nitrogen, and urine protein were measured according to the instructions of the creatinine, urea nitrogen, and urine protein assay kits to assess renal function. The levels of inflammatory factors IL-1β, IL-6, and TNF-α were measured according to the instructions of the IL-1β, IL-6, and TNF-α assay kits to assess the level of renal inflammation in the mice. ALT and AST were measured according to the instructions of the ALT and AST assay kits to assess liver function. Histopathology: Kidney and liver tissues were collected and fixed in 4% paraformaldehyde for 24 hours. After dehydration, they were embedded in paraffin blocks and cut into 4-μm sections. The sections were oven-dried at 65°C for 1 hour. After gradient dewaxing with organic reagents, they were stained with hematoxylin and eosin, Masson staining, and immunohistochemistry to observe histopathological changes, inflammatory infiltration, and the degree of fibrosis.

[0040] GraphPad Prism 9.4.1 software was used for data analysis and plotting. Two-group comparisons were performed using a two-tailed unpaired t-test, and multiple group comparisons were performed using one-way ANOVA with Tukey's multiple comparison test. Data are presented as mean ± standard error. P < 0.05 indicates that the difference is statistically significant.

[0041] Experimental results:

[0042] 1. Improve hyperuricemia

[0043] The uric acid levels of mice in each group are shown in Table 1. Compared with the blank control group, the serum uric acid and XOD enzyme levels in the model group were significantly increased, and the urine uric acid level was significantly decreased. After drug intervention, the serum uric acid level was significantly decreased, while the urine uric acid level was significantly increased, and the liver xanthine oxidase level was significantly decreased, indicating that this prescription can significantly improve hyperuricemia.
