Islet β cell dedifferentiation is one of the important reasons leading to insulin secretion defect or insulin resistance in patients with type 2 diabetes mellitus(T2DM).HIF-1α/PFKFB3 signaling pathway is a newly discovered biological pathway related to T2DM,which is involved in the induction of islet β cells dedifferentiation by anaerobic glycolysis under high glucose environment.This article reviews the research progress of the role of HIF-1α/PFKFB3 signaling pathway in glycolysis induced islet β cell dedifferentiation.

The theory of " heart governing the exterior" derives from Prohibition of Pricking in Suwen, which has an important position in the clinical practice of traditional Chinese medicine. This article sorts out the interpretation of " heart governing the exterior" of physicians in the past dynasties, and summarizes the clinical application of " heart governing the exterior" in chest painful impediment, warm disease, dermatosis, allergic rhinitis, tic disorder, and diabetic neuropathy. It is found that the theory of " heart governing the exterior" is widely used in clinical practice and has good effects. This paper further expands and enhances its theoretical connotation, that is, the physiological and pathological connection and clinical application of the three dimensions of heart yang, heart blood, and heart spirit with the life and mental activities dominated by it, as well as the overall external performance. In addition, by exploring the relationship between " heart governing the exterior" and " brain-heart axis" , " brain-skin axis" in Western medicine, it indirectly confirms the rationality of " heart governing the exterior" in Western medicine, and lays the foundation for the further development and application of the theory of " heart governing the exterior" .
