Prescription for NAFLD Based on Relationship Between Intestinal Microecology and Spleen-stomach's Ascending and Descending Theory / 中国实验方剂学杂志

ABSTRACT

Non-alcoholic fatty liver disease (NAFLD) is a kind of metabolic stress liver injury, which has become one of most common chronic liver diseases in China and even world. Therefore, the occurrence and development of NAFLD and its prevention and treatment have been attracted more and more attention. The disturbance of intestinal microecology, especially intestinal flora, is one of important factors leading to NAFLD. The syndrome traceability, etiology and pathogenesis of nafld in traditional Chinese medicine (TCM) are related to imbalance of spleen-stomach's ascending and descending. The effect of NAFLD treatment depends on spleen-stomach's ascending and descending. The intestinal tract is main part for realizing spleen-stomach function according to principle of TCM. Intestinal flora is a regulation factor affecting host metabolism, which is consistent with biological connotation of TCM principle of spleen-stomach's ascending and descending. Because spleen-stomach's ascending and descending disorder is consistent with symptoms of intestinal flora imbalance, intestinal flora is closely related to spleen-stomach's ascending and descending in TCM. Based on modern intestinal micro-ecosystem, this paper expounds theoretical basis for treatment of NAFLD based on relationship between spleen-stomach's ascending and descending in TCM, and on that basis, ideas of prescription and medication for NAFLD were put forward, mainly including invigorating spleen and replenishing Qi and ascending clearity, regulating Qi-flowing and regulating stomach and descending turbidity, resolving phlegm, activating blood circulation and dissipating accumulation, and dominant role in coordinating spleen-stomach's ascending and descending and intestinal microecology is highlighted in treatment of NAFLD. Soothing liver and regulating Qi, dispersing and descending lung-Qi, ascending clearity and descending turbidity, and warming and activating kidney-Yang, synergistic factors for onset of NAFLD were taken into account to promote spleen-stomach's ascending and descending functions, and therapeutic effect shall be considered from perspective of intestinal microecology. After retention enema with Chinese herbs, transporting function of large intestine might be activated to help stomach-Qi descending and coordinate spleen-stomach's ascending and descending, and intestinal microecological mechanism of drug delivery channel intervening NAFLD may be studied based on 16s rDNA gene pathway. With deepening of research on intestinal flora, relationship between it and spleen-stomach's ascending and descending and NAFLD will be further revealed, which not only inherits China's long history of applying spleen-stomach's ascending and descending to treat liver diseases, but also expand perspective of regulating intestinal microecolog(intestinal flora) in treatment of NAFLD.
