Description

Technical Field

[0001] The present invention belongs to the technical field of biological medicines, and specifically relates to a Chinese medicinal probiotic composition for treating fatty liver and optimizing intestinal flora and an application thereof. Background Art

[0002] With the change of lifestyle and the adjustment of dietary structure, the prevalence of fatty liver has increased year by year. It is reported that the prevalence of fatty liver in the global population is about 25%. Some studies have also pointed out that the increase in liver mortality is related to the increase in the prevalence of non-alcoholic fatty liver disease (NAFLD). Non-alcoholic fatty liver disease (NAFLD) is an acquired metabolic stress liver injury with hepatocyte fatty degeneration and fat accumulation as the main clinical features. Excessive fat deposition in the liver not only affects the normal function of the liver, but may also lead to a series of serious complications, such as cirrhosis and liver cancer. At present, the treatment of fatty liver mainly includes improving diet, increasing exercise, and drug therapy. Although improving diet and increasing exercise have certain effects on patients with mild fatty liver, it is often difficult to achieve ideal therapeutic effects for moderate and severe patients. Drug treatment mainly includes lipid-lowering drugs, antioxidant drugs, anti-inflammatory drugs, etc. These drugs can improve liver function to a certain extent, but long-term use may lead to side effects and drug dependence. Therefore, finding a safer and more effective treatment for fatty liver has become a hot topic in current research.

[0003] In recent years, with the in-depth study of the pathogenesis of fatty liver, more and more treatment methods have been proposed and applied in clinical practice, including gene therapy, stem cell therapy, immunotherapy, etc. Traditional Chinese medicine and probiotics, as two treatment methods with broad application prospects, have received widespread attention in the treatment of fatty liver in recent years. With its multi-component and multi-target characteristics, Chinese medicine has unique advantages in regulating human metabolism and improving liver function, and has also shown significant advantages in the treatment of obesity and fatty liver. Probiotics also show good effects on the treatment of fatty liver by regulating the balance of intestinal flora and affecting the host's metabolism and immune function.

[0004] Traditional Chinese medicine treatment emphasizes the overall concept and syndrome differentiation and treatment. Traditional Chinese medicine theory believes that the pathogenesis of gallstones and fatty liver is the following two points: one is liver qi stagnation and emotional depression; the other is unclean diet, intake of high-calorie, high-cholesterol foods, and both are mainly for treating "dampness". Therefore, the formula used to treat gallstones should also have a good effect in treating fatty liver in theory, that is, the principle of "different diseases treated with the same method" in traditional Chinese medicine theory. In recent years, with the deepening of modern research on traditional Chinese medicine, more and more traditional Chinese medicine ingredients and compound preparations have been found to have anti-obesity and anti-fatty liver effects, providing a scientific basis for the treatment of obesity and fatty liver with traditional Chinese medicine. For example, Lysimachia chinensis has the effect of relaxing gallbladder smooth muscle, promoting cellular cholesterol outflow, and improving intracellular lipid accumulation; Scutellaria baicalensis and others can resist oxidation and scavenge free radicals, chronically treat hepatitis, and resist liver fibrosis. Studies have shown that Chinese medicine can regulate the imbalance of intestinal flora, maintain the homeostasis of intestinal flora, and protect the intestinal mucosa. It can directly or indirectly regulate the imbalance of intestinal flora by supporting the number of intestinal probiotics and causing the intestinal translocation of probiotics, thereby inhibiting the reproduction of pathogenic bacteria. However, whether Chinese medicine regulates the flora to exert its therapeutic effect or the flora absorbs Chinese medicine to make it work still needs further research to prove.

[0005] Studies have shown that intestinal flora plays a key role in obesity and lipid metabolism. For example, both in vitro and in vivo experiments have confirmed that lactobacillus can reduce serum lipids, low-density lipoproteins and triglyceride levels. Studies have found that the intake of lactic acid bacteria can significantly reduce liver fat content and reduce liver inflammation and fibrosis, but its relief mechanism has not yet been elucidated and is strain specific. Bifidobacterium is a common probiotic that has the functions of regulating intestinal flora and enhancing immunity. It can also reduce the production of harmful substances in the intestine and reduce liver fat deposition, thereby improving fatty liver. The intestinal flora can regulate liver metabolism through the gut-liver axis, and there are a large number of studies that have explored the gut-liver axis mechanism in depth from the aspects of enzyme function and transcriptional regulation.

[20] However, due to the complex structure of the compounds in the metabolic process and the long metabolic pathways, there are still many gaps in this field, and the relationship between intestinal flora and liver metabolism still needs further experiments to explore. Summary of the invention

[0006] In view of this, the purpose of the present invention is to provide a Chinese herbal probiotic composition for treating fatty liver and optimizing intestinal flora.

[0025] The present invention provides the use of the Chinese medicinal probiotic composition, the Chinese medicinal composition or Lactobacillus plantarum in the above scheme in preparing a medicine for preventing and / or treating intestinal damage in patients with fatty liver and / or regulating the balance of intestinal flora.

[0026] The present invention provides a Chinese medicine probiotic composition, comprising a Chinese medicine composition and probiotics; the Chinese medicine composition comprises the following components in parts by weight: 28-32 parts of Lysimachia chinensis, 8-10 parts of Scutellaria baicalensis, 8-10 parts of Toosendan fruit, 8-10 parts of Aucklandia lappa and 5-7 parts of Rhubarb; the probiotics include Lactobacillus plantarum. The Chinese medicine composition of the present invention is a stone-removing prescription for treating gallstones, and Lactobacillus plantarum is combined with the Chinese medicine composition, which is beneficial to drug absorption and enhances the efficacy of the Chinese medicine. The present invention uses a fatty liver mouse model as an experimental subject. Compared with the model group, the combined lactobacillus expelling stone prescription treatment group can improve the problem of enlarged liver of the model mouse, yellowish color and greasy texture, and significantly reduce liver weight; HE staining and oil red O staining results show that compared with the model group, the combined lactobacillus expelling stone prescription treatment group can improve the problems of different sizes of liver cells, disordered arrangement, smaller liver sinusoids, a large number of fat vacuoles in liver cell health care, and obvious inflammatory infiltration in the model mouse, and the NAS score is significantly reduced. It can be seen that the combined lactobacillus expelling stone prescription treatment group can improve the liver tissue morphology of the model mouse. At the same time, the combined lactobacillus expelling stone prescription treatment group can significantly reduce the concentration of TG and LDL-C in the liver, significantly reduce the concentration of serum TNF-α, and regulate the expression of genes related to fatty acid metabolism. It can be seen that the lactobacillus combined expelling stone prescription affects the synthesis of fatty acids, the metabolism of cholesterol, and the uptake of lipoproteins by inhibiting the expression levels of these three indicators, thereby improving the liver metabolism abnormalities caused by fatty liver, and then serving the purpose of treating fatty liver. In addition, the combined treatment group of Lactobacillus and Paishi Fang can improve the intestinal tissue morphology of fatty liver model mice to normal morphology, improve the intestinal mucosal damage of fatty liver mice, and significantly change the intestinal flora compared with the fatty liver model group, increasing the total number and abundance of species. It can be seen that Lactobacillus combined with Paishi Fang can also regulate the intestinal flora of patients with fatty liver, improve the intestinal barrier, and have the potential to alleviate fatty liver.

[0048] The present invention provides a Chinese medicine probiotic composition, comprising a Chinese medicine composition and probiotics;

[0049] The Chinese medicine composition comprises the following components in parts by weight: 28-32 parts of Lysimachia chinensis, 8-10 parts of Scutellaria baicalensis, 8-10 parts of Toosendan fruit, 8-10 parts of Aucklandia lappa and 5-7 parts of Rhubarb;

[0050] The probiotics include Lactobacillus plantarum.

[0051] In the present invention, the Chinese medicine composition preferably includes the following components in parts by mass: 30 parts of Lysimachia chinensis, 9 parts of Scutellaria baicalensis, 9 parts of Toosendan fruit, 9 parts of Aucklandia lappa and 6 parts of Rhubarb.

[0052] In the present invention, the Chinese medicine composition preferably comprises a decoction. The preparation method of the decoction comprises the following steps: soaking Lysimachia chinensis, Scutellaria baicalensis, Toosendan fruit, Aucklandia lappa and Rhubarb in water, then decocting, and separating the decoction.

[0053] In the present invention, the soaking time is preferably 50 to 70 minutes, and more preferably 60 minutes. During the soaking, the mass ratio of the total mass of the Herba Lysimachiae, Baical Scutellariae, Fructus Toosendan, Aucklandiae Radix and Rhubarb to water is preferably 1: (7 to 9), and more preferably 1: 8. The soaking is conducive to the rapid release of the active ingredients in the Chinese medicinal materials. During the decoction, when the mixture of Chinese medicine and water is boiled to boiling, water is added to continue the decoction, and the liquid phase is separated to obtain a Chinese medicine decoction. The added mass of the water is preferably 5 to 7 times the total mass of the Herba Lysimachiae, Baical Scutellariae, Fructus Toosendan, Aucklandiae Radix and Rhubarb, and more preferably 8 times. The continued decoction time is preferably 5 to 10 minutes, and more preferably 8 minutes. The Chinese medicine probiotic composition preferably includes a Chinese medicine decoction containing Lactobacillus plantarum. The live bacteria concentration of Lactobacillus plantarum is 1×10 5 ~1×10 10 CFU / mL, more preferably 1×10 8 CFU / mL. The plant lactobacillus preferably includes the plant lactobacillus strain DM9125. The plant lactobacillus strain DM9125 has been disclosed in the prior art, specifically the prior art (Effects of single, double and triple probiotics on the recovery and immunity of intestinal flora imbalance mice, Gu Jie, Dalian Medical University, 2023, 6, Master's thesis) records plant lactobacillus (DM9125).

[0054] In the present invention, the preparation method of the Chinese medicine probiotic composition preferably comprises the following steps:

[0055] Prepare a Lactobacillus plantarum bacterial liquid, separate the bacterial bodies, and resuspend the bacterial bodies in the Chinese medicine decoction. The method for preparing the Lactobacillus plantarum bacterial liquid preferably inoculates the activated Lactobacillus plantarum in a selective liquid culture medium and cultures it for 14 hours. The selective liquid culture medium is preferably 200 ml / L tomato juice, 15 g / L peptone, 20 g / L glucose, 6 g / L yeast extract powder, 5 g / L sodium chloride, 1 ml / L Tween, and 0.5 g / L soluble starch. The culture temperature is preferably 36 to 38 ° C, more preferably 37 ° C. The culture time is preferably 12 to 15 hours, and most preferably 14 hours.

[0056] In the present invention, Lactobacillus plantarum can improve the intestinal flora and keep it in a steady state. The lipid-lowering effect of lactic acid bacteria alone is not obvious. The Chinese medicine composition is combined with Lactobacillus plantarum strain DM9125 to improve fatty liver while keeping the intestinal flora in a steady state, thereby further enhancing the efficacy of the Chinese medicine composition in preventing and treating fatty liver.

[0057] The present invention provides the use of the Chinese medicinal probiotic composition, the Chinese medicinal composition or Lactobacillus plantarum in the above scheme in preparing a medicine for preventing and / or treating fatty liver.

[0058] In the present invention, the treatment of fatty liver is preferably manifested in at least one of the following aspects: relieving liver inflammation, improving liver status and regulating liver metabolism. The relieving of liver inflammation preferably includes inhibiting the expression of endotoxin LPS and inflammatory cytokines IL-1β, IL-6, and TNF-α. The regulating liver metabolism includes regulating the expression levels of lipid synthesis-related molecules SREBP-1c, FAS, LXR, CD36, and PPARγ.

[0059] In an embodiment of the present invention, the effect on liver morphology, compared with the model group, the Chinese medicine probiotic composition and the Chinese medicine composition can significantly reduce liver weight, the Chinese medicine composition can significantly reduce liver index, plant lactobacillus, Chinese medicine probiotic composition and the Chinese medicine composition can significantly reduce NAS score and ORO value. For the influence of liver biochemical indexes, plant lactobacillus and Chinese medicine probiotic composition can significantly reduce TG concentration in liver, plant lactobacillus, Chinese medicine probiotic composition and the Chinese medicine composition can significantly reduce LDL-C concentration. For the influence of immune indexes, plant lactobacillus and Chinese medicine probiotic composition can significantly reduce the concentration of proinflammatory factor TNF-α. The treatment of fatty liver mice by Paishi Fang and Lactobacillus may be achieved by reducing oxidative stress or inhibiting the expression of inflammatory factors.

[0060] In the present invention, SREBP-1c (sterol regulatory elementbinding protein-1c) is an important target in the treatment of fatty liver. It is a transcription factor that plays a key regulatory role in lipid metabolism. In fatty liver, the expression level of SREBP-1c usually increases, and it mainly exacerbates the development of fatty liver by promoting the synthesis of fatty acids and triglycerides. SREBP-1c can also activate the transcription of enzymes such as acetyl-CoA carboxylase and fatty acid synthase (fatty acid synthase, FAS), thereby increasing the synthesis rate of fatty acids. FAS (fatty acid synthase) is a key enzyme in the fatty acid synthesis process, which catalyzes the continuous condensation reaction from acetyl-CoA to palmitate. Therefore, in the case of fatty liver, due to the activation of transcription factors such as SREBP-1c, the expression and activity of FAS usually increase, resulting in increased synthesis of fatty acids, further exacerbating the condition of fatty liver. LXR (liver X receptor) is a nuclear receptor that can regulate cholesterol and fatty acid metabolism by regulating SREBP-1c. After binding to the ligand, LXR can activate the transcription of a series of target genes, including cholesterol transport proteins ABCA1 and ABCG1, and fatty acid synthase FAS, etc. The present invention uses fluorescent quantitative PCR detection to show that compared with the fatty liver group, the relative expression of SREBP-1c, FAS, and LXR in the three-way treatment group all showed a downward trend, and the effect of the Paishifang treatment group was the most significant. This shows that Paishifang and Lactobacillus may affect the synthesis of fatty acids, the metabolism of cholesterol, and the uptake of lipoproteins by inhibiting the expression levels of these three indicators, thereby improving the liver metabolic abnormalities caused by fatty liver, and then achieving the purpose of treating fatty liver.

[0061] In the present invention, CD36, also known as fatty acid translocase, plays a key role in lipid metabolism and signal transduction. Abnormal increase of CD36 can increase the uptake of fatty acids and lipid accumulation in hepatocytes, thereby promoting the occurrence and development of fatty liver. Studies have shown that rhubarb can reduce insulin resistance and improve diabetes by regulating the PPARγ pathway. PPARγ, i.e. peroxisome proliferator-activated receptor γ, mainly regulates gene expression and glucose metabolism and the storage of fatty acids. Studies have shown that PPARγ-LXR is the core of regulating SREBP gene transcription and SREBP mRNA stability. In fatty liver, the activation of PPARγ may stimulate the differentiation and fat storage of adipocytes, thereby aggravating the condition of fatty liver. Therefore, a lower level of PPARγ expression in the liver may have certain benefits. The results of fluorescence quantitative PCR showed that compared with the fatty liver group, the expression of CD36 and PPARγ in the three-way treatment group showed a downward trend, and the Paishifang treatment group and the lactobacillus treatment group had better effects. This once again proves that Paishifang and lactobacillus can achieve the purpose of improving the metabolism of fatty liver in mice by reducing the uptake and storage of fatty acids.

[0062] The present invention provides the use of the Chinese medicinal probiotic composition, the Chinese medicinal composition or Lactobacillus plantarum in the above scheme in preparing a medicine for preventing and / or treating intestinal damage in patients with fatty liver and / or regulating the balance of intestinal flora.

[0063] In the present embodiment, after HE staining of the intestinal tissue of mice, it was found that the villi structure of the fatty liver group was of different lengths, the internal gaps became larger, and the muscle layer became thinner. This may be due to intestinal flora imbalance and abnormal lipid metabolism, which led to increased levels of inflammatory factors in the body and caused intestinal tissue damage. The intestinal tissue morphology of the three treatment groups was improved to a certain extent. In addition, changes in the intestinal flora structure will promote LPS entry into the blood by changing intestinal permeability, thereby increasing the level of inflammation.

[0064] In the present invention, the fecal flora of each group of mice was first analyzed by PCR-DGGE method, and then two groups with better intervention effects were selected based on the above experiments. The Paishifang group and the lactobacillus group were subjected to 16S rRNA high-throughput sequencing analysis of the fecal specimens of mice. We found that the intestinal flora of the Paishifang group and the lactobacillus group changed significantly compared with the fatty liver group, such as the increase in the total number and richness of species, the bacterial abundance of Firmicutes and Allobaculum decreased, and the bacterial abundance of Bacteroidota, Actinobacteriota, norank_f__Muribaculaceae, Faecalibaculum and Ileibacterium increased. It is pointed out in the literature that some bacteria in Firmicutes are related to energy harvesting and fat storage, and their increase in number may promote excessive absorption of energy and accumulation of fat, thereby aggravating the development of fatty liver. The increase in Allobaculum may be related to the destruction of intestinal barrier function and the release of inflammatory mediators, which may be involved in the pathological process of fatty liver. The metabolism of some bacteria in Bacteroidota is related to fat absorption, and their reduction may affect the host's energy intake and utilization, thereby affecting the synthesis and accumulation of fat. Some bacteria in Bacteroidota have anti-inflammatory effects, and their reduction may lead to a decrease in the anti-inflammatory ability of the intestine and the whole body. Some bacteria in Actinobacteriota also have the ability to regulate immune responses, and some bacteria may be involved in cholesterol metabolism. The reduction in their abundance may affect the balance of cholesterol, which is also an important factor in the development of fatty liver. Similar to the increase in Firmicutes and Allobaculum, the reduction in Bacteroidota and Actinobacteriota may be a sign of the development of fatty liver, and may also be directly involved in the occurrence and development of the disease. The research results of this example show that the Paishi prescription and Lactobacillus intervention treatment can regulate the intestinal flora of mice with fatty liver, thereby improving the intestinal barrier and having the potential effect of alleviating fatty liver.

[0065] The following is a detailed description of a Chinese medicinal probiotic composition for treating fatty liver and optimizing intestinal flora and its application provided by the present invention in conjunction with the embodiments, but they should not be construed as limiting the scope of protection of the present invention.

[0212] 5.1 Changes of intestinal flora of mice by PCR-DGGE under the three-way intervention

[0213] Fig.13The PCR-DGGE changes of intestinal flora of normal control group (N) mice before and after modeling. Fig.13 A1 and A2 in the middle are PCR-DGGE band diagrams of intestinal flora DNA of normal control group mice before and after modeling. It can be seen from the figure that the fecal DNA bands of control group mice increased after modeling; Fig.13 B1 and B2 show the results of UPGMA similarity cluster analysis. 1-4 are the control groups before modeling, and 5-8 are the control groups after modeling. The results show that the mice before and after modeling are in one cluster each, indicating that the intestinal flora of the control group mice changed before and after modeling. Fig.13 C1 and C2 show the results of principal component analysis. 1-4 are the control groups before modeling, and 5-8 are the control groups after modeling. It can be seen that the distance between the groups is relatively close. Therefore, the Shannon index and richness of mice were calculated based on the bands for further analysis. Fig.13 D and E in the middle are the Shannon index and richness of the control group mice before and after modeling, respectively. It can be seen that there are significant differences in the Shannon index and richness (P < 0.05).

[0214] Fig.14 The PCR-DGGE changes of intestinal flora in the normal control group (N) and the fatty liver group (M) after successful modeling. Fig.14 A1 and A2 in the middle are PCR-DGGE band diagrams of intestinal flora DNA of mice in the normal control group (N) and fatty liver group (M) after successful modeling. It can be seen from the figure that the fecal DNA bands of mice in the fatty liver group (M) were reduced after successful modeling; Fig.14 B1 and B2 show the results of UPGMA similarity cluster analysis. Fig.14 In B1, 1-4 are the normal control group (N), 5-8 are the fatty liver group (M), Fig.14 In B2, 1-4 are the normal control group (N), and 5-9 are the fatty liver group (M). The results show that the mice in the normal control group (N) and the fatty liver group (M) are in a cluster, indicating that the intestinal flora of mice changed after the model was successfully established; Fig.14 C1 and C2 show the results of principal component analysis. Fig.14 In C1, 1-4 are the normal control group (N), 5-8 are the fatty liver group (M), Fig.14 In C2, 1-4 is the normal control group (N), and 5-9 is the fatty liver group (M). It can be seen that the distance between the groups is relatively close. Therefore, the Shannon index and richness of the mice were calculated based on the bands for further analysis. Fig.14 D and E in the middle are the Shannon index and richness of the normal control group (N) and fatty liver group (M) mice after successful modeling. It can be seen that both the Shannon index and richness of the normal control group (N) are greater than those of the fatty liver group (M), but there is no statistical difference.

It can be seen from the figure that the fecal DNA bands of the experimental group mice were slightly reduced; Fig.15 B shows the results of UPGMA similarity cluster analysis. 1-3 is the normal control group (N), 4-6 is the Paishifang treatment group (C), 7-9 is the lactobacillus treatment group (P), 10-12 is the combined lactobacillus Paishifang treatment group (CP), and 13-15 is the fatty liver group (M). The results show that the normal control group (N) is clustered alone at 0.59, the Paishifang treatment group (C) is clustered alone at 0.81, and the lactobacillus treatment group (P) is clustered alone at 0.74. Although the combined lactobacillus Paishifang treatment group (CP) and the fatty liver group (M) are not clustered alone, they are all around 0.71. Fig.15 Figure C shows the results of principal component analysis. 1-3 are the normal group (N), 4-6 are the group treated with the Stone-Removing Formula (C), 7-9 are the group treated with Lactobacillus (P), 10-12 are the group treated with the combined Lactobacillus Stone-Removing Formula (CP), and 13-15 are the fatty liver group (M). It can be seen that the distances within each group are relatively close, but the distances between the three groups of samples, the Stone-Removing Formula (C), the Lactobacillus (P) and the fatty liver group (M), are also relatively close. Therefore, the Shannon index and richness of mice were calculated according to the bands for further analysis. It can be seen from Table 8 that after 6 weeks of intervention, compared with the normal control group (N), the Shannon index and richness of the fatty liver group (M) showed significant changes (P < 0.01), and the Shannon index and richness of the Lactobacillus treatment group (P) and the combined Lactobacillus stone-removing prescription treatment group (CP) were also significantly changed compared with the normal control group (N) (P < 0.01), but there was no statistical difference between the stone-removing prescription treatment group (C) and the normal group (N).

[0230] like Fig.19 As shown in Figure A, from the phylum level results, compared with the fatty liver group (M), the abundance of Firmicutes bacteria in the Paishifang treatment group (C) and the Lactobacillus treatment group (P) was reduced, and Fig.19 As shown in B, the abundance of Firmicutes bacteria in the Paishifang treatment group (C) was significantly reduced (P < 0.05), and Firmicutes was the dominant bacteria in this period; compared with the fatty liver group (M), the abundance of Bacteroidota and Actinobacteriota bacteria in the Paishifang treatment group (C) and the Lactobacillus treatment group (P) increased.

[0231] like Fig. 20As shown in A, the sequencing results at the subordinate level show that compared with the fatty liver group (M), the bacterial abundance of norank_f__Muribaculaceae, Faecalibaculum and Ileibacterium in the Paishifang treatment group (C) and the Lactobacillus treatment group (P) increased; Fig. 20 As can be seen from Figure C, compared with the fatty liver group (M), the abundance of Allobaculum bacteria in the Paishifang treatment group (C) and the Lactobacillus treatment group (P) was significantly reduced (P < 0.001).

[0232] 5.2.3 Lefse analysis of intestinal flora

[0233] The intestinal flora of mice was analyzed by Lefse to find the differential bacteria with LDA score ≥ 4 in each stage. The results are as follows Fig.21As shown: the characteristic differential bacteria in the fatty liver group (M) were p_Firmicutes, c_Bacilli, o_Erysipelotrichales, f_Erysipelotrichaceae, g_Allobaculum, g_Lachnoclostridium, o_Lactobacillales, f_Lactobacillaeae, g_Lactobacillus, g_Dubosiella, and o_Petostreptococcales-Tissierellales; the characteristic differential bacteria in the Paishifang treatment group (C) were g_lleibacterium, c_Coriobacteriia, o_Coriobacteriales, g_norank_f__Desulfovibrionaceae, p__Actinobacteriota, f_Desulfovibrionaceae, p_Desulfobacterota, and p_Proteo bacteria, c_Gammaproteobacteria, o_Desulfovibrionales, c_Desulfovibrionia, g_Coriobacteriaceae_UCG-002, f_Atopobiacea, o_Burkholderiales, g_Parasutterella, f_Sutterellaceae; the characteristic differential bacteria in the Lactobacillus treatment group (P) were g_Faecalibaculum, g_unclassified_f_Lachnospiracea, g_Bacteroides, f_Bacteroidaceae, g_norank_f__Eubacterium_coprostanoligenes_group, f_Eubacterium_coprostanoligenes_group, g_Blautia, g_norank_f__Erysipelotrichaceae. The specific differential bacteria in the normal control group (N) were f_Muribaculaceae, g_norank_f__Muribaculaceae, o_Bacteroidales, c_Bacteroidia, p_Bacteroidota, g_Lachnospiraceae_NK4A136_group, and g_Lachnospiraceae_UCG-010.

[0234] In this example, male C57BL / 6J mice with fatty liver were treated with the stone-removing prescription, lactobacillus intervention, and combined lactobacillus stone-removing prescription for 6 consecutive weeks, and the basic indicators of each group of mice were monitored; tissue sections were used to observe the histomorphological changes of the liver and intestines; enzyme method and ELISA method were used to detect the biochemical and immune indicators of each group of mice; fluorescent quantitative PCR method was used to detect the changes in RNA expression of liver metabolism-related indicators of each group of mice; PCR-DGGE method was used to preliminarily explore the changes in intestinal flora, and 16S rRNA high-throughput sequencing analysis was used to study the specific changes in intestinal flora of each group of mice. Finally, the effects of various intervention methods on liver metabolism and intestinal flora of mice with fatty liver were comprehensively analyzed.

[0235] The weight of mice was monitored weekly, and it was found that during the whole experiment, the weight of mice in each treatment group decreased compared with the fatty liver group. This shows that the three-way intervention treatment of Paishi Fang, Lactobacillus Fang and combined Lactobacillus Paishi Fang can improve the weight of mice, but there is no statistical difference between the Paishi Fang treatment group and the Lactobacillus treatment group and the fatty liver group, probably because the intervention time is slightly short. After Oil Red O staining and HE staining of the liver tissue of mice, it was found that the liver cords in the fatty liver group were disordered, there were a large number of fat vacuoles, and the inflammatory infiltration was obvious. This may be due to the excessive accumulation of fat in the liver cells, which damaged the liver cells and then triggered an inflammatory response, leading to changes in liver tissue morphology. After HE staining of the intestinal tissue of mice, it was found that the length of the villi structure in the fatty liver group was different, the internal gap became larger, and the muscle layer became thinner. This may be due to the imbalance of intestinal flora and abnormal lipid metabolism, which led to the increase of the level of inflammatory factors in the body and caused intestinal tissue damage. The liver and intestinal tissue morphology of the three-way treatment group was improved to a certain extent.

[0236] In this example, the fecal flora of each group of mice was first analyzed by PCR-DGGE method, and then two groups with better intervention effects were selected based on the above experiments, and 16S rRNA high-throughput sequencing analysis was performed on the fecal specimens of mice in the Paishifang group and the Lactobacillus group. We found that the intestinal flora of the Paishifang group and the Lactobacillus group changed significantly compared with the fatty liver group, such as the increase in the total number and richness of species, the bacterial abundance of Firmicutes and Allobaculum decreased, and the bacterial abundance of Bacteroidota, Actinobacteriota, norank_f__Muribaculaceae, Faecalibaculum, and Ileibacterium increased.

[0237] The research results of this example show that the Paishi prescription and Lactobacillus intervention treatment can regulate the intestinal flora of mice with fatty liver, thereby improving the intestinal barrier and having the potential effect of alleviating fatty liver.

[0238] In summary, the present embodiment is through Paishifang, lactobacillus, joint lactobacillus Paishifang to fatty liver mice intervention treatment after 6 weeks, combined with each group of mice basic index, histomorphological changes, immune index, liver tissue RNA relative expression and intestinal flora, the conclusion drawn is: Paishifang, lactobacillus, joint lactobacillus Paishifang treatment can effectively improve fatty liver mice liver, intestinal tissue state, can also be by suppressing the expression of inflammatory cytokines, down-regulate the expression of lipid synthesis related molecules, thereby alleviate fatty liver metabolic abnormalities, and comprehensively Paishifang treatment group effect is better. Paishifang, lactobacillus, joint lactobacillus Paishifang treatment can also regulate mouse intestinal flora, improve intestinal barrier, have the potential effect of alleviating fatty liver. Chinese medicine and probiotics are complex mechanisms in the treatment of fatty liver, and the present embodiment provides part of the theoretical basis and data support, and further experimental verification and clinical research are necessary.

[0239] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
