Analysis on Relationship Between Intestinal Flora and Diabetes Cognitive Impairment Based on "Paired Relationship Between Heart and Small Intestine" / 中国实验方剂学杂志

ABSTRACT

Based on theory of "paired relationship between the heart and the small intestine" in traditional Chinese medicine（TCM）， heart disease can affect the small intestine， and intestinal diseases can also affect the heart. The heart controls mental activities， so if the secretions function of small intestine is impaired， it will hinder the mind of the mind. Modern medicine has found that intestinal flora is closely related to cognitive function， which is consistent with the "paired relationship between heart and small intestine" in TCM. Diabetes cognitive impairment （DCI） is a category of "diabetes dementia" in TCM. According to TCM， the imbalance of spleen and stomach is the starting factor of diabetes dementia， and the phlegm turbidity of spleen deficiency is the pathological product of diabetes dementia. Previous projects have proved that intestinal flora disturbance is the modern pathological basis of spleen and stomach imbalance in TCM， suggesting that restoring spleen and stomach function to adjust intestinal microbial homeostasis is helpful for the prevention and treatment of diabetes dementia. At present， many achievements have been made in the study of the mutual causality between diabetes and intestinal flora disorder. In recent years， the incidence of DCI has increased rapidly， and the pathogenesis is complex and unclear， which increases the difficulty of treatment. Therefore， finding new targets should not be ignored. Given the complex connections among intestinal flora， diabetes and cognitive impairment， it is particularly important to tease out the relationship among the three. Based on previous scientific research， the author analyzed layer by layer and found that intestinal flora can not only affect the synthesis of neurotransmitters in the brain， but also participate in the common pathogenesis of diabetes and cognitive impairment such as chronic inflammation， insulin resistance and blood glucose rise， with a typical target effect. The pathogenic mechanism of intestinal flora in DCI was summarized in order to establish a new target and direction for the treatment， and to explore the scientific connotation of TCM in regulating spleen and stomach for treatment of diabetes dementia.
