Description

Application of traditional Chinese medicine composition in preparation of medicine for treating organ fibrosis
Technical Field
The invention relates to the technical field of traditional Chinese medicines, in particular to an application of a traditional Chinese medicine composition in preparing a medicine for treating organ fibrosis.
Background
Fibrosis (fibrosis) is an important pathological change of various diseases, the cause of which is complex, and which can lead to impairment or even loss of normal tissue function. The major pathological changes of fibrosis are increased fibrous connective tissue in organ tissue, reduced parenchymal cells, and continued progression can lead to destruction and hypofunction of organ structures, and even failure. Fibrosis can be caused by chronic inflammatory reactions caused by factors such as infection, autoimmune reactions, allergic reactions, and chemo-radiation stimulation, the common route of which is fibroblast activation proliferation. Fibrosis can occur in various organs, such as the lung, liver, kidneys, heart, etc., resulting in fibrosis of the viscera.
Organ fibrosis is a pathological change of fibrous connective tissue increase and parenchymal cytopenia in organ tissues caused by various acute and chronic lesions, and excessive remodeling, hardening and scarring of various organ tissues, and a common pathological basis is abnormal increase and excessive deposition of extracellular matrix (extracellular matrix, ECM). Among them, kidney fibrosis is a common pathway for various chronic kidney diseases to progress to end-stage renal failure, the essence of which is "scarring" repair following injury to kidney tissue; pulmonary fibrosis is the final outcome of the development, evolution, and scarring of pulmonary diseases; liver fibrosis is a repair response of the liver to chronic injury, a pathological change common to chronic liver disease; myocardial fibrosis is an important marker for decompensated myocardial hypertrophy and heart failure, and is involved in myocardial remodeling caused by hypertension, hypertrophic cardiomyopathy, heart failure and myocardial infarction.
At present, fibrosis of parenchymal organs such as heart, liver, lung and kidney is a main cause of organ failure and disability and death of patients, and when important organs such as heart, lung and liver are fibrosed, the important organs are not treated timely and effectively, so that the organs are hardened or the organs are failure, physiological and psychological health of human beings is endangered, and even life is endangered. However, due to the lack of in-depth knowledge of the pathogenesis of organ fibrosis, there is a clinical lack of biomarkers for early diagnosis and early warning, and few therapeutic drugs specifically directed to fibrosis are available.
Although organ transplantation is the most remarkable clinical solution for the final stage of organ fibrosis, most patients cannot benefit due to the problems of scarcity, low survival rate, high cost, rejection after transplantation, high infection risk and the like of the donor, so that the finding of other treatment solutions with more remarkable curative effects, safer application and simpler operation is still a clinical urgent problem to be solved.
Disclosure of Invention
Aiming at the technical problems existing in the prior art of organ fibrosis of the aged, the invention provides application of a traditional Chinese medicine composition in preparing a medicine for treating organ fibrosis.
In order to achieve the aim of the invention, the invention adopts the following technical scheme:

Test example:
to elucidate the effect of the drug of the present invention on improving the degree of visceral fibrosis weakness, the following experiment was conducted using example 1 (hereinafter referred to as the drug of the present invention or BZBS):
1. animal experiment for pulmonary fibrosis
A single tracheal injection of bleomycin was used to model pulmonary fibrosis in mice. Male ICR mice (SPF grade) were divided into a blank group, a model group, and a pirfenidone group (manufacturing company: beijing Kanti pharmaceutical Co., ltd.) and BZBS group at random according to body weight of 22-25 g. The animals were subjected to tracheal injection surgery, the blank group was injected with physiological saline, and the remaining groups were injected with bleomycin (manufacturer: japanese chemical Co., ltd.). BZBS group administration dose is folded crude drug dose of 2g crude drug/kg/d, pirfenidone group administration dose is 300mg/kg/d, corresponding volume solvent (CMC) is given to blank group animals and model group animals, stomach irrigation administration is carried out, administration is started on the molding day, and continuous administration is carried out for 21 days.
After the administration, the weight change of the animals is observed by weighing, the liquid nitrogen is placed after the whole lung is weighed, the lung coefficient is calculated, the result is shown in table 1, and the result is shown in table 2. Part of the animals were stained for Masson's lung perfusion fixation and the lung tissue fibrosis was examined and the results are shown in table 3 and fig. 1 (lung tissue Masson staining pattern (20×), including blank, model, pirfenidone and BZBS groups).
Figure DEST_PATH_IMAGE001
Figure 63473DEST_PATH_IMAGE002
Figure DEST_PATH_IMAGE003
From the above data, the model group showed significantly increased lung coefficient (P < 0.01) compared with the blank group, and significantly decreased lung coefficient (P < 0.05) compared with the BZBS group and pirfenidone group; meanwhile, compared with a blank group, the hydroxyproline content of the model group is obviously increased (P is less than 0.05); compared with the model group, the BZBS group and the pirfenidone group have obviously reduced hydroxyproline content (P < 0.05); furthermore, the BZBS and pirfenidone groups have relatively low lung fibrosis scores compared to the model group. The BZBS has the effects of inhibiting the pulmonary fibrosis degree of mice caused by bleomycin and preventing and treating the pulmonary fibrosis.
2. Animal experiment for myocardial fibrosis
50 male SD rats (SPF grade) were 2 months old, and had a weight of 200+ -10 g, and purchased from Beijing Vetong Lihua laboratory animal technology Co., ltd. The animal raising conditions are 12 hours/day of illumination, the temperature is 20-26 ℃, the relative humidity is 40-70%, the animals are fed with maintenance feed (supplied by Australian feed Co., beijing family), clean water prepared by a ROA50 experimental animal drinking system is drunk, animals are quarantined for 3 days, the animals are adaptively raised for 2 days, and drinking water, ingestion and health conditions of the animals and whether disease and death symptoms exist or not are observed in the period.
The 50 SD rat random number table method was divided into 5 groups: the drug intervention was performed in the normal group (normal diet + isovolumetric solvent gavage), in the model group (normal diet + isovolumetric solvent gavage), in the BZBS low dose group (normal diet + BZBS 1g/kg/d gavage), in the BZBS high dose group (normal diet + BZBS 4g/kg/d gavage), and in the Sha Kuba troxatan control group (normal diet + 20mg/kg/2d gavage), as shown in table 4. The administration modes of the test substances are BZBS high-dose group, BZBS low-dose group and control group, wherein the daily gastric lavage drug solution is 10mL/kg, and the normal group and the model group are the daily gastric lavage of the same volume solvent CMC.
Figure 918296DEST_PATH_IMAGE004
The model making method comprises the following steps: SD rats were fed adaptively for 1 week, weighed, injected intraperitoneally with 10% chloral hydrate (0.35 g/kg), fixed on the rat plates in right lateral recumbent position after anesthesia, shaved in right quaternary rib area, and left kidney area exposed; sterilizing the kidney region with 75% alcohol, making a longitudinal incision along the free edge of the left twelve ribs of the spine, taking a length of about 1-2cm, performing blunt stripping to remove the muscle layer, finding out the kidney, performing extrusion exposure, stripping fat around the kidney, and exposing the artery and vein of the kidney and ureter; the hemostatic forceps fix the kidney, ligate the whole arteriovenous and ureter with the 4-0 operation suture line, and cut off the kidney; sequentially suturing the visceral layer and the muscular layer, performing abdominal cavity injection with 10000u row of penicillin, wiping off excessive blood, placing the rats on an electric blanket for heat preservation, and placing the rats back into a squirrel cage for feeding after observing the stable vital signs, wherein 1% saline water is used for drinking and free diet. After 4 weeks, the heart function of the rat is detected by using a small animal ultrasonic instrument, and EF is more than 50%, and the E/A ratio is reduced, so that the establishment of the chronic heart failure model is successful.
After 2 months of administration, the rat is anesthetized with isoflurane, the rat is waited for losing consciousness, the abdominal aorta is taken for blood after the rat is anesthetized, after standing for 2 hours at normal temperature, the serum is taken after centrifugation for 15 minutes at 3000r, and the rat is preserved at-80 ℃ for standby. The heart tissue is taken and fixed in 4% paraformaldehyde solution, and one part of the heart tissue is placed in a freezing tube and stored at-80 ℃ for standby. Part of the heart was subjected to Masson and HE staining to observe the morphological changes of heart tissue. The results are shown in fig. 2 (same group in each column, different groups in each column), and Masson staining patterns at different magnifications (10×, 20×, and 40×) for the normal group, model group, control group, BZBS low dose group, and BZBS high dose group. Masson staining showed that the cardiomyocytes of the normal group of rats were ordered, the cells were not necrotic, and no significant collagen fibroplasia was observed. The model group can be used for treating a large number of myofiber cracks, atrophy and degeneration, the blue dyeing degree of collagen fiber is heavy, the fibrosis degree of myocardial cells is obviously increased, and the myocardial cells are stiff. The administration groups (control group, BZBS low dose group and BZBS high dose group) lighten the myocardial fibrosis degree in different degrees.
Simultaneously, the cross-sectional area of myocardial cells is measured by immunofluorescence, myocardial tissue sections are taken, dewaxing, antigen repair and endogenous peroxidase blocking are performed, 3% BSA is blocked for 30 min at room temperature, primary antibody is incubated overnight at 4 ℃, secondary antibody is incubated for 1 h in dark, DAPI (4', 6-diamidino-2-phenylindole) is used for dying cell nuclei, and neutral resin is used for sealing. 3 discrete fields were randomly selected under a microscope, and staining results were observed, as shown in fig. 3 (each column is the same group, and different columns correspond to different groups respectively), wheat Germ Agglutinin (WGA) appears green, alpha smooth muscle actin (alpha-SMA) appears red, DAPI appears blue, and amber particles are positive cells in an immunofluorescent staining chart (20×). WGA staining showed an increase in cardiomyocyte cross-sectional area in the model group over the normal group, morphologically confirming the presence of myocardial hypertrophy. The cardiomyocyte size (P < 0.05) was significantly restored in each of the dosing groups (control, BZBS low dose, BZBS high dose). There was no significant difference in the perivascular α -SMA expression levels for each of the dosing groups.
From the data, BZBS can obviously reduce the collagen content of myocardial tissues of rats with chronic heart failure, reduce the cross-sectional area of myocardial cells, reduce the degree of myocardial fibrosis, inhibit the reconstruction of the left ventricle, and further improve the heart function of the rats.
3. Animal experiment of kidney fibrosis
15 male BKS-DB (WT) mice (weighing about 19-30 g) were used as a blank group, 45 male BKS-DB mice (weighing about 40-69 g) were used as an experimental group, and the animal source was Jiangsu Jiuzhikang Biotech Co. Animals in the experimental group begin to be fed with high-fat high-protein diet at the age of 8 weeks, and blood sugar and urine biochemical (mAlb/CREA) indexes of the animals are detected after continuous feeding for 8 weeks, so that diabetic nephropathy symptoms are achieved. Animals in the experimental group were divided into a model group, a BZBS group and a dapagliflozin group according to blood sugar, 15 animals in each group were administered on the day of grouping, 1 time/day, and 6 weeks continuously. BZBS group administration dose is 1.44g crude drug/kg/d, dapagliflozin group administration dose is 1mg/kg/d, and the blank group and model group animals are given equal volume of water. After the completion of the administration, each group was examined for renal fibrosis and urine biochemistry, and the results are shown in fig. 4 (renal tissue staining chart (10×)) and tables 5 and 6. Compared with the model group, the urine biochemical index of the BZBS group is obviously reduced (P < 0.05).
Figure DEST_PATH_IMAGE005
Figure 698034DEST_PATH_IMAGE006
From the above data, it can be seen that the urine biochemical (mAlb/CREA) index of the test animals is significantly improved and the degree of renal fibrosis is significantly reduced after BZBS administration for 6 weeks.
