Description

Traditional Chinese medicine composition for treating urinary calculus and application and preparation thereof
Technical Field
The invention belongs to the field of medical treatment and health, and particularly relates to a traditional Chinese medicine composition for treating urinary calculus, application thereof and a preparation method of traditional Chinese medicine composition granules.
Background
Urinary calculus, abbreviated as urolithiasis, refers to the concentration and precipitation of urine in the urinary system to form particles or lump-like aggregates, which can be classified into the following types according to the location of the calculus: kidney stone, ureteral stone, vesical stone, urethral stone, etc., are common diseases and frequently encountered diseases worldwide. The reported incidence rate of urinary calculus is up to 5-15%, the recurrence rate is almost 50%, and the incidence rate is also rising. Renal colic and hematuria are commonly caused clinically, and the calculi can be embedded, blocked and cause hydronephrosis and secondary urinary infection; renal insufficiency may also occur in the later stage. The research at home and abroad shows that the causes of the urinary calculus are complex, and the formed mechanism is mainly the product formed by abnormal accumulation of crystal substances such as calcium oxalate and the like of the urinary system and organic matters. Clinically, calculus consisting of calcium oxalate, calcium phosphate or a mixture of the calcium oxalate and the calcium phosphate accounts for 95 percent, and the calculus is the most common type of calculus containing calcium. Aiming at the treatment of urinary calculus, a specific method is not available in pure drug treatment, and a treatment means combining a surgical operation and an external shock wave lithotripsy technology is mainly adopted at present. Although the external shock wave lithotripsy technology is widely applied clinically, urinary system calculus is greatly improved in treatment, but the defects of residual calculus, high recurrence rate, physiological pain brought to patients and the like still exist in operative treatment and external shock wave lithotripsy. Therefore, how to remove the residual calculus to the maximum extent and prevent and treat calculus recurrence still remains two major problems for clinical treatment of urinary calculus.
In traditional Chinese medicine, urinary calculus belongs to the categories of lumbago, sandlin, urolithiasis and hematuria. The traditional Chinese medicine theory considers that the main pathogenesis of stranguria is that damp-heat accumulates in lower-jiao urine, and the urine accumulates day by day and month, and impurities in the urine are accumulated into sand. Especially, modern people who have no good diet and overeat spicy, fat and sweet substances have failure of transportation and transformation of the spleen and stomach, accumulation of dampness and heat, downward flow of the liver-qi to the bladder, or stagnation of liver qi and obstruction of collaterals by blood stasis due to large living pressure, so that damp-heat in the lower-jiao, unfavorable gasification, deposition of sand stranguria and disfavor of water channels cause repeated and delayed disease conditions. Therefore, the basic principle that 'clearing damp-heat in lower jiao and inducing diuresis for treating stranguria and dissolving stones' are used as Chinese herbal medicines for treating urinary calculus is determined, and the formula is prepared according to the main pathogenesis characteristics of the urinary calculus such as 'damp-heat', 'sand stranguria' and 'stasis' through years of clinical exploration, so that the formula is prepared by combining syndrome differentiation and disease differentiation, emphasizing the efficacy characteristics and pharmacological action of the traditional Chinese medicines and avoiding the toxic and side effects and incompatibility of the traditional Chinese medicines. The Chinese herbal medicine which is widely accepted in clinic by pharmacological action in the treatment of urinary calculus is selected to form a proved formula, namely eight-ingredient desmodium styracifolium urinary calculus removing decoction, the formula is a proved formula which is unique in traditional Chinese medicine and is attached to the first hospital of the medical college of Zhejiang university, the desmodium styracifolium in the formula is a monarch medicine and has the effects of clearing heat, promoting urination and removing urinary calculus, and polysaccharide substances can obviously inhibit the crystal growth of calcium oxalate; the fringed pink has the effects of clearing away heart heat, benefiting damp heat of small intestine and bladder, increasing ureteral peristalsis and dilating ureter; che Qian Zi can induce diuresis and treat stranguria, and tonify kidney, so as to induce diuresis without damaging kidney yin; herba Desmodii Styracifolii, herba Dianthi, and semen plantaginis can also acidify urine, dissolve calculus, inhibit calcium absorption, and prevent calculus from forming; talcum can remove dampness and heat, induce resuscitation and relieve stranguria; the liquorice can directly reach the anterior vagina urethra to play the effects of relieving spasm and pain; rhizoma Ligustici Chuanxiong has effects of promoting blood circulation, activating qi-flowing, dispelling pathogenic wind and relieving pain; achyranthes root, radix Achyranthis bidentatae has the effects of nourishing liver and kidney, and strengthening tendons and bones. The whole formula has the effects of clearing damp-heat in lower-jiao, promoting urination, treating stranguria, removing calculus and preventing calculus recurrence. Based on the theory of traditional Chinese medicine, the Chinese herbal medicine formula of the invention shows special advantages for removing residual urinary calculus and preventing and treating calculus recurrence in clinical use, and clinical summary shows that the formula has remarkable curative effect on treating urinary calculus, low calculus recurrence rate, safety and economy. However, the traditional decoction is inconvenient for patients to take, often fails to take, and is not suitable for the fast-paced life style of modern people. Therefore, the eight-ingredient desmodium styracifolium urinary calculus removing decoction is prepared into a solid preparation, namely eight Chinese herbal medicines such as desmodium styracifolium, dianthus superbus, semen plantaginis, pyrrosia lingua and the like are extracted and processed into granules which are convenient for patients to use, and the granules are respectively prepared into common granules and sugar-free granules for the patients with diabetes and non-diabetes.
