Abstract
- The paper aimed to explore the mechanism by which high mobility group box-1 and nicotinamide adenine dinucleotide phosphate oxidase-derived reactive oxygen species enhance each other's influence on the amplitude of electroretinogram and the permeability of the vitreous. According to the purpose of the experiment, the experimental rats were separated into a control group, a diabetes group and a Shenling Baizhu powder group. The messenger ribonucleic acid expression of microRNA-23 and microRNA-27a in rat muscle tissue was quantitatively analyzed by real-time quantitative polymerase chain reaction. The contractility of rat soleus skeletal muscle was analyzed by electrical stimulation program. Western blot analysis of rat muscle growth protein synthesis and the expression of myostatin signaling pathway was carried out. The expression of renal fibrosis-related albumin was tested by Western blot. The messenger ribonucleic acid expression of microRNA-23, 27a in the diabetic group was lower than control group (p<0.05), and the expression in the Shenling Baizhu powder group was higher than diabetic group (p<0.05). Compared with the control group, the diabetic group had lower body weight (p<0.05), and raised blood glucose concentration and diabetes volume (p<0.05). The ratio of phosphorylated protein kinase B/protein kinase B and phospho forkhead box protein O1/forkhead box protein O1 protein expression in the Shenling Baizhu powder group was higher than diabetic group (p<0.05), while the phosphatase and tensin homolog protein expression was lower (p<0.05). The protein expression of myostatin, FBXO32 and TRIM63 in the diabetes group was higher than control group (p<0.05), and the expression in the Shenling Baizhu powder group was lower than diabetes group (p<0.05). Compared with the control group, the protein expression of transforming growth factor-beta, suppressor of mothers against decapentaplegic 2/3, alpha-smooth muscle actin, collagen-1a and fibronectin was higher in the diabetes group (p<0.05), and the expression in the Shenling Baizhu powder group was lower than diabetes group (p<0.05). Shenling Baizhu powder can improve diabetes-induced sarcopenia by up-regulating microRNA expression, activating the insulin-like growth factor 1/phosphoinositide 3-kinases/ protein kinase B signaling pathway and inhibiting the myostatin cascade.
