Description
Technical Field
The invention relates to the field of microorganisms, in particular to a probiotic composition with a function of relieving hyperuricemia and application thereof.
Background
With the improvement of living standard of people, the incidence of a plurality of chronic diseases is higher, such as hyperuricemia and the like. Hyperuricemia is a disease in which blood uric acid exceeds normal values, and uric acid is easily precipitated in joints, soft tissues, cartilage and kidneys in the form of sodium salt, causing organ and tissue lesions of the human body, resulting in gout and serious complications. According to statistics, the number of hyperuricemia patients is about 1.2 hundred million in China at present, and the traditional treatment methods comprise the problems of drug dependence, great side effect, difficult diet control and the like in the aspects of drugs, diet restriction and the like, so that the development of a new method for preventing and relieving the symptoms of hyperuricemia is not slow.
Hundreds of millions of bacteria inhabit the human intestinal tract, most of which live in symbiosis with the human body and form a unique micro-ecosystem. Researches find that intestinal micro-ecological imbalance is one of the key factors causing diseases, and the regulation of intestinal microbial flora and the improvement of the internal environment of the intestinal tract by using probiotics become research hotspots for preventing and treating related diseases, and a plurality of researches show that the probiotics have remarkable effects on relieving diarrhea, constipation, hypertension, hyperglycemia and the like. In the aspect of intervention of hyperuricemia by probiotics, dalian medical university breeds and obtains a Lactobacillus brevis DM9218 and recombinant protein (CN 106834162A) thereof, and the decomposition rates of inosine and guanosine are 99.31 percent and 99.64 percent respectively. Gold (screening of probiotic strains for reducing blood uric acid and exploration of mechanism of reducing blood uric acid, page 1757-1769 of 8 th stage in 2018 of microbiological report) and the like, further widens the range of degraded substrates, and breeds a lactobacillus casei ZM15 which can efficiently degrade nucleosides (adenosine and guanosine) and nucleotides (adenylic acid and guanylic acid), and can alleviate symptoms of hyperuricemia to a certain extent. The applicant also applies for lactobacillus gasseri LG08 with the effect of degrading uric acid and application thereof (Chinese application number CN201911191600. X), has excellent nucleoside and nucleotide degradation capability, can decompose most precursors synthesized by uric acid, reduce absorption of the precursors synthesized by uric acid by organisms, can directly and efficiently decompose uric acid in intestinal tracts, and further inhibit the generation of uric acid and relieve inflammation and the like by reducing the serum endotoxin level and inhibiting the xanthine oxidase activity.
However, it should be noted that, the above mentioned methods all use a single probiotic to intervene in hyperuricemia, and the species of the used probiotic is small, compared with the large number of flora in human intestinal tract, the effect of regulating intestinal flora by using a single probiotic is limited and the synergistic effect between multiple probiotics cannot be exerted. Furthermore, hyperuricemia is accompanied by various side effects such as dysbacteriosis and increased intestinal wall permeability, etc., and the above single strain protocol focuses on the effect of reducing uric acid concentration without intensive studies on the mitigating effects of other side effects. Finally, in the preparation process, the problems of stability and the like of probiotics in the storage process are not fully considered in the scheme, so that the problems of too fast loss of viable count, weakening of effect and the like are easily caused.

Wherein, the serum uric acid is detected by a TBHBA (2, 4, 6-tribromo-3-hydroxybenzoic acid) method.
Fecal flora detection is performed by continuously diluting a sample by 10 times, sampling 0.2mL, coating the sample on LBS, TPY, EMB, enterococcus agar plate and TSC culture medium, performing anaerobic culture at 37 ℃ for 48h, and performing plate counting detection on lactobacillus, bifidobacterium, enterobacter, enterococcus and clostridium perfringens respectively, wherein the results are shown in Table 3.
Lipopolysaccharide (LPS) detection was performed using a Lipopolysaccharide (LPS) detection kit (Shanghai Xinyu Biotechnology, inc.).
The inflammatory factor assay was performed using an enzyme linked immunosorbent assay kit (Abcam antibody coating, UK).
TABLE 3 detection of intestinal flora in rats (lg CFU/g feces)
Regarding the serum uric acid level detection, the results are shown in fig. 1, after 7 days of continuous intraperitoneal injection of potassium oxonate and supplementation of a high-purine diet, the blood uric acid content of rats in the model group, the allopurin drug intervention group and each probiotic intervention group is significantly increased, which indicates that the hyperuricemia model is successfully established. The intervention groups were then started with different formulations of probiotic composition and allopurin drug intervention for 21 days. From the results, examples 1 to 3 are superior to comparative examples 1 and 2. Therefore, when the addition amount of the probiotics is not in the range disclosed by the invention, the effect of the obtained probiotic composition on relieving uric acid is not obvious. In addition, compared with the auxiliary material formula (comparison example 3) consisting of single probiotics and prebiotics, the composite probiotic composition consisting of different probiotics and prebiotics can more effectively reduce the content of uric acid in serum under the same intake amount. Comparative examples 1 to 3 showed the best effect of reducing uric acid and the effect of example 3 was superior to that of the allopurin drug group.
The fecal flora change measurements are shown in Table 3. Bifidobacteria and lactic acid bacteria are generally considered to be beneficial microorganisms for the gut, helping to maintain the gut microbiota balance. On the contrary, enterobacteria, enterococci and clostridium perfringens are harmful bacteria and easily produce toxins, etc. The comparison result shows that the examples 1, 2 and 3 can effectively improve the content of lactic acid bacteria and bifidobacteria in the intestinal tract, and obviously reduce the content of harmful bacteria, namely enterobacteria, enterococcus and clostridium perfringens, and the effect is better than that of the comparative examples 1 and 2. Therefore, when the adding amount of the probiotics is not in the range disclosed by the invention, the obtained probiotic composition has no obvious effect of relieving the flora imbalance caused by hyperuricemia. In addition, the result of comparing the auxiliary material formula consisting of single probiotics and prebiotics (comparative example 3) shows that the adjusting effect of the probiotic composition on the flora is obviously better than that of the formula made of single probiotics. On the other hand, it was found after comparison of examples 1 to 3 that the formulation of example 3 has an optimum effect on the regulation of the intestinal flora.
Lipopolysaccharide and inflammatory factors are important factors influencing inflammation generation and can be used as one of important indexes reflecting in-vivo inflammation degree, hyperuricemia is often accompanied by side reaction of in-vivo inflammation aggravation, lipopolysaccharide can also be used as an important index reflecting intestinal permeability, and the increase of the content of lipopolysaccharide in blood indicates that the barrier effect of intestinal mucosa is reduced and the intestinal permeability is increased. On the other hand, lipopolysaccharide and proinflammatory factor IL-6 are important potential substances for generating inflammation, and the anti-inflammatory factor IL-10 can inhibit antigen presentation and inflammatory cytokine production. As shown in FIGS. 2 and 3, the results of measurement of LPS and inflammatory factors are shown in examples 1, 2 and 3, which are superior to those of comparative examples 1 and 2 in the effects of effectively reducing the contents of LPS and proinflammatory factor IL-6 and increasing the content of anti-inflammatory factor IL-10 in rats. It can be seen that when the addition amount of the probiotics is out of the range disclosed in the invention, the obtained probiotic composition has no obvious effect on relieving the side effect of hyperuricemia (inflammation improvement and intestinal mucosa barrier enhancement). In addition, the result of comparing the auxiliary material formula consisting of single probiotics and prebiotics (comparative example 3) shows that the regulation effect of the probiotic composition on the flora is obviously better than that of the formula made of single probiotics. On the other hand, it was found that the formulation of example 3 is optimal for the improvement of inflammation and enhancement of the intestinal mucosal barrier after comparative examples 1-3.
2. Stability test
The prepared probiotic composition is placed under the storage condition of 25 ℃ and 75% of relative humidity, the tracking monitoring period is set to be 2 years, the total number of lactobacillus of the product is detected in 0, 3, 6, 9, 12, 15, 18, 21 and 24 months respectively, the detection scheme adopts the lactobacillus detection method in the national standard GB 4789.35, and the detection result is shown in figure 4.
As can be seen from the results in fig. 4, the viable count of the lactic acid bacteria in the probiotic composition prepared by the boiling granulation treatment (example 3) is reduced slowly, and the survival rate of the lactic acid bacteria after 24 months can reach 66.7%, compared with the viable count of the lactic acid bacteria in the probiotic composition without the boiling granulation treatment (comparative example 4), which is reduced rapidly, and the survival rate of the lactic acid bacteria after 24 months is only 3.3%, indicating that the screening rate of the probiotic bacteria can be significantly reduced and the stability of the probiotic composition can be effectively improved by performing the boiling drying treatment on the auxiliary materials including polydextrose, resistant dextrin and fructo-oligosaccharide to control the water content and water activity.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, it should be noted that, for those skilled in the art, many modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
