Abstract:
Studies have shown that metabolic diseases, such as obesity, are significantly associated with intestinal flora imbalance. The amplification of opportunistic pathogens induced by the glyoxylic acid cycle contributes to intestinal flora imbalance. Promising, though, is that saturated hydrogen can effectively improve the occurrence and development of metabolic diseases, such as obesity. However, the specific mechanism of how saturated hydrogen operates is still not very clear. In this study, after a high-fat diet, the level of total cholesterol, total glyceride, and low-density lipoprotein in the peripheral blood of mice increased, and that of high-density lipoprotein decreased. Intestinal fatty acid metabolism-related gene Apolipoprotein E (ApoE), fatty acid synthase (FAS), intestinal fatty acid-binding protein (I-FAPB), acetyl-CoA carboxylase 1 (ACC1), peroxisome proliferator-activated receptor γ (PPARγ), and stearoyl-CoA desaturase 1 (SCD1) increased significantly. Bacteroides, Bifidobacteria, and Lactobacillus counts in feces decreased considerably, while Enterobacter cloacae increased. The activity of isocitrate lyase in feces increased markedly. Treatment of mice with saturated hydrogen led to decreased total cholesterol, total glyceride, and low-density lipoprotein and increased high-density lipoprotein in the peripheral blood. FAS and I-FAPB gene expression in the small intestine decreased. Bacteroides, Bifidobacteria, and Lactobacillus in feces increased significantly, whereas Enterobacter cloacae decreased. The activity of isocitrate lyase also diminished remarkably. These results suggest that saturated hydrogen could improve intestinal structural integrity and lipid metabolism disorders by inhibiting the glyoxylic acid cycle of the intestinal flora.
