[0053] As shown in Figure 3 , the AOS group, the example 5 group and the comparative example group respectively used the coarse oligosaccharide of sand rush, the composite preparation obtained in example 5 and the composite preparation obtained in comparative example, which all had protective effect on the formation of diabetic osteoporosis.
[0054] As shown in Figure 4 and Figure 5As shown, Tb.BV / TV, Ct.Th and Tb.N of the model group were significantly lower than those of the blank control group (P<0.05), and Tb.BV / TV, Ct.Th and Tb.N of the AOS group, the example 5 group and the comparative example group were significantly higher than those of the model group (P<0.05), wherein Tb.BV / TV, Ct.Th and Tb.N of the example 5 group were the highest (P<0.05); SMI of the model group was significantly higher than that of the blank control group (P<0.05), and SMI of the AOS group, the example 5 group and the comparative example group was significantly lower than that of the model group (P<0.05), and SMI of the example 5 group was significantly lower than that of the AOS group and the comparative example group (P<0.05).
[0055] The reason for the above results is that the sodium carboxymethyl cellulose used in the application has good compatibility with sodium alginate, and after the two are compounded by hydrogen bonds and then solidified, the obtained microspheres have high stability, the hydrolysis product of the sodium carboxymethyl cellulose hydrolyzed by cellulase penetrates from the inside to the outside of the microspheres, the internal void structure of the product is uniform, which is beneficial to the stable loading of the psammochloa crude oligosaccharide, and the hydrogen bond complex of the lactoferrin peptide and the resveratrol makes the psammochloa crude oligosaccharide not easy to overflow, and the loading stability is high. The application realizes the slow release and intestinal targeted delivery of the psammochloa crude oligosaccharide, avoids the degradation of gastric acid, and the hydrogen bond complex of the lactoferrin peptide and the resveratrol further reduces the risk of burst release of the psammochloa crude oligosaccharide and prolongs its half-life. The psammochloa crude oligosaccharide cooperates with the lactoferrin peptide and the resveratrol to improve insulin resistance (IR) and correct the bone resorption-formation imbalance of diabetic osteoporosis (DOP).
[0056] The above is only a preferred specific embodiment of the application, but the protection scope of the application is not limited thereto, and any person skilled in the art can make equivalent replacements or changes to the technical solution and the inventive concept of the application within the technical range disclosed by the application, which should be covered within the protection scope of the application.
