Background: Type 2 diabetes mellitus (T2DM) is a chronic metabolic disease that has turned up as dimensions of the pandemic all over the world. In China, some traditional Chinese herbal formulas have enjoyed a high reputation in T2DM treatment for centuries. Methods: In this study, ShenQi compound (SQC) is proposed, a formula has been performed on T2DM clinical therapeutics in China for many years. The efficacy of SQC in diabetic rat model by measuring food and water intake and examining islet microcirculatory index involves islets microvessel quantity and density, islets size, pancreatic microvascular wall thickness is evaluated. Meanwhile, gene microarray experiments were performed to explore the molecular mechanism of SQC treatment. In addition, a western medicine, metformin was employed as a comparison. Results: The results indicated that SQC could effectively improve polydipsia, polyphagia and weight loss caused by diabetes as well as pancreatic tissue damage and vascular injury for T2DM. Meanwhile, the gene microarray experiments indicated that SQC may improve the T2DM through affecting the biological functions related to detection of chemical stimulus involved in sensory perception of smell, G-protein coupled receptor signaling pathway, cytoplasmic translation. In addition, SQC presented curative effect by regulated function associated with translation, while metformin presented curative effect by regulated function associated coagulation. Conclusion: SQC is an effective therapeutic drug on T2DM, and present curative effect by regulated function associated with translation.

Type 2 diabetes mellitus is one of the most frequent causes of death in Mexico, characterized by chronic hyperglycemia. One alternative strategy for this metabolic abnormality is inhibiting the enzymes responsible for the metabolism of carbohydrates. We evaluated whether the aqueousCitrus limettapeel extract could inhibit the metabolism of carbohydrates. We found that this extract inhibited primarily the enzymeα-amylase by 49.6% at a concentration of 20 mg/mL and to a lesser extent the enzymeα-glucosidase with an inhibition of 28.2% at the same concentration. This inhibition is likely due to the high polyphenol content in theCitrus limettapeel (19.1 mg GAE/g). Antioxidant activity of theCitrus limettapeel demonstrated dose-dependent antioxidant activity, varying from 6.5% at 1.125 mg/mL to 42.5% at 20 mg/mL. The study of these polyphenolic compounds having both antihyperglycemic and antioxidant activities may provide a new approach to the management of type 2 diabetes mellitus.
