ABSTRACT
This study aimed to explore the effect of Salviae Miltiorrhizae Radix et Rhizoma, its stems and leaves on the diversity of intestinal microflora in rats with diabetic kidney injury. Diabetic rats model was established by feeding high glucose and high fat diet and 5% glucose solution with intraperitoneal injection of 30 mg·kg~(-1) streptozocin(STZ). The rats were randomly divided into normal group, model group, irbesartan control group, Huangkui Capsules control group, as well as low, middle and high dose groups of Sal-viae Miltiorrhizae Radix et Rhizoma, its stems and leaves. After administration for 2 weeks, 16 S rRNA technique was used to analyze the diversity of intestinal microflora in the feces of each group. The results showed rats in the model group developed renal tubular epithelial vacuole degeneration and a large amount of inflammatory cell infiltration in the renal interstitium. A small amount of inflammatory cell infiltration was seen in each administration group. The kidney structure of rats in irbesartan group, Huangkui Capsules group, high-dose group of Salviae Miltiorrhizae Radix et Rhizoma and its stem water extract, as well as high dose group of Salviae Miltiorrhizae Radix et Rhizoma and its stem ethnol extract group was close to the normal group. The diversity and structure of intestinal flora in the model group were significantly different from those in the normal group. Each administration group improved the fecal flora diversity in rats with diabetic kidney injury to a certain extent, especially the high dose of Salviae Miltiorrhizae Radix et Rhizoma and its stems water extract. Different flora were found in feces of diabetic nephropathy model rats on class, order, family and genus levels. On families and genera levels, the relative abundance of Bifidobacterium, Turicibacter, Peptostreptococcaceae, Desulfovibrio, and SMB53 showed an upward trend in model group, but that of Lactobacillus, Clostridium, Rikenella, Rumen fungi showed a downward trend. The administration groups can improve the relative abundance of the above intestinal flora in the model rats to a normal-like level. The results of this study provide a reference for resource utilization and further development of Salviae Miltiorrhizae Radix et Rhizoma.
