Abstract
Diabetes is a significant chronic endocrine/metabolism disorder that can result in a number of life-threatening consequences. According to research, the gut microbiota is strongly linked to the development of diabetes, making it a viable target for diabetes treatment. The intestinal microbiota affects intestinal barrier function, organism immunity, and thus glucose metabolism and lipid metabolism. According to research, a disruption in the intestinal microbiota causes a decrease in short-chain fatty acids (SCFAs), alters the metabolism of bile acids (BAs), branched-chain amino acids (BCAAs), lipopolysaccharide (LPS), and endotoxin secretion, resulting in insulin resistance, chronic inflammation, and the progression to type 2 diabetes mellitus (T2DM). Astragali Radix is a medicinal herb of the same genus as food that has been extensively researched for treating diabetes mellitus with promising results in recent years. Polysaccharides, saponins, flavonoids, and other components are important. Among them, Astragaloside has a role in protecting the cellular integrity of the pancreas and liver, can leading to alleviation of insulin resistance and reducing blood glucose and triglyceride (TC) levels; The primary impact of Astragalus polysaccharides (APS) on diabetes is a decrease in insulin resistance, encouragement of islet cell proliferation, and suppression of islet β cell death; Astragali Radix flavonoids are known to enhance immunity, anti-inflammatory, regulate glucose metabolism and control the progression of diabetes. This study summarizes recent studies on Astragali Radix and its group formulations in the treatment of type 2 diabetes mellitus by modulating the intestinal microbiota.

Abstract
Dysbiosis of the gut microbiota's composition and function is important in developing insulin resistance and diabetes. Diabetes has also been linked to changes in the circulating and fecal metabolites. Evidence suggests the associations between the gut microbiota and the aberrant diabetes-related metabolome. Metabolites play a crucial role in the host-microbiota interactions. Researchers have used a combination of metagenomic and metabolomic approaches to investigate the relationships between gut microbial dysbiosis and metabolic abnormalities in diabetes. We summarized current discoveries on the associations between the gut microbiota and metabolites in type 1 diabetes, type 2 diabetes, and gestational diabetes mellitus in the scoping review. According to research, the gut microbiota changes might involve in the development of diabetes through modulating the host's metabolic pathways such as immunity, energy metabolism, lipid metabolism, and amino acid metabolism. These results add to our understanding of the interplay between the host and gut microbiota metabolism.

Song W, Song C, Li L, Wang T, Hu J, Zhu L, Yue T. Lactobacillus alleviated obesity induced by high-fat diet in mice. J Food Sci 2021; 86:5439-5451. [PMID: 34859434 DOI: 10.1111/1750-3841.15971] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2021] [Revised: 09/28/2021] [Accepted: 10/15/2021] [Indexed: 11/28/2022]
Abstract
Obesity is closely related to dyslipidaemia, diabetes and other metabolic syndromes. Long-term consumption of a high-fat diet (HFD) is an important risk factor that can lead to obesity. In the current research, three Lactobacillus strains, namely, Loigolactobacillus coryniformis subsp. torquens T3 (T3), Lacticasebacillus paracasei subsp. paracasei M5 (M5), and Lacticaseibacillus paracasei subsp. paracasei X12 (X12), were tested to determine their inhibitory effects on HFD-induced obesity. The results showed that M5, T3, and X12 significantly decreased the body weight gain, Lee's index and adipose index. T3 showed significant effects on reducing serum TG levels to 0.92 mmol/ml and increasing HDL-C levels to 2.18 mmol/ml. The M5 treatment significantly reduced the serum TG level and leptin content to 1.11 mmol/ml and 3.7 ng/ml, respectively, and it increased the HDL-C level and adiponectin content to 2.35 mmol/ml and 7 ng/ml, respectively. M5 and T3 dramatically ameliorated hepatic steatosis in HFD-treated mice by reducing the liver index, lipid droplet number in the liver and TC levels in the liver. Gene expression of PPAR-γ and TNF-α was notably downregulated and FAS was upregulated by T3 and M5 treatment. Additionally, administration of M5 and T3 modified the diversity of the gut microbiota with increased OTU number, ACE index, and Chao1, and decreased the Shannon index and the Bacteroidetes /Firmicutes ratio. Overall, our results indicate that Lactobacillus may be used to prevent obesity and gut dysbiosis. PRACTICAL APPLICATION: Lactobacillus from traditional Chinese foods showed strong anti-obesity effects on high-fat diet-fed mice through the regulation of adipocytokines. Additionally, administration of certain Lactobacilli modified the diversity of the gut microbiota. The results indicate that Lactobacillus may be promising functional materials in healthy foods.
