ABSTRACT
In recent decades, the mortality and morbidity of diabetes have increased such that it is becoming a major worldwide public health problem. Intensive blood glucose control could significantly raise the patients life and their survival quality nevertheless it develops hypoglycaemia. Repeated hypoglycemia leads to glucose conterregulate deficiencyand hamper reaching glucose target goals. Astragalus, a traditional Chinese herb used in diabetic therapy for thousands years, has also proven its glucose counterregulationeffect on preventing hypoglycemia. Here, we summarize its glycemic regulation mechanism in different extracts. It is projected that the efficacy and safety of astragalus extracts will be proven in clinical trials and animal experiments in future, and this herb extract might be known as a new class of anti-diabetic drug without hypolycemia danger.
ABSTRACT
The central nervous system (CNS) plays a key regulatory role in glucose homeostasis. In particular, the brain is important in initiating and coordinating protective counterregulatory responses when blood glucose levels fall. This may due to the metabolic dependency of the CNS on glucose, and protection of food supply to the brain. In healthy subjects, blood glucose is normally maintained within a relatively narrow range. Hypoglycemia in diabetic patients can increase the risk of complications, such as heart disease and diabetic peripheral neuropathy. The clinical research finds that the use of traditional Chinese medicine (TCM) has a positive effect on the treatment of hypoglycemia. Here the authors reviewed the current understanding of sensing and counterregulatory responses to hypoglycemia, and discuss combining traditional Chinese and Western medicine and the theory of iatrogenic hypoglycemia in diabetes treatment. Furthermore, the authors clarify the feasibility of treating hypoglycemia on the basis of TCM theory and CNS and have an insight on its clinical practice.
