Narrative review of the mechanisms of action of dachengqi decoction in the treatment of hyperlipidemic pancreatitis on six-hollow-organs to be unblocked theory

: The incidence rate of acute pancreatitis (AP) caused by hyperlipidemia is increasing year by year. The primary treatment goal is to reduce blood lipids rapidly. On the theory of "Six-hollow-organs to be unblocked" we used dachengqi decoction (original prescription of Zhang Zhongjing in Shanghan Lun) to block the peroxisome proliferator-activated receptor γ (PPARG) pathway and rapidly reduce blood lipid to achieve the purpose of treating hyperlipidemic acute pancreatitis (HLAP). In this review, we summarize the etiology and pathogenesis of HLAP and the progress of traditional Chinese medicine in treating HLAP. The mechanisms of action of dachengqi decoction in the treatment of HLAP and the involvement of the PPARG pathway were discussed. In brief, the dachengqi decoction has the effect of resolving phlegm and clearing waste substances and can improve intestinal function; can inhibits the production of interleukin-1, interleukin-6, and tumor necrosis factor-α, and reduces the damage of SIRS to human body; also it improves the microcirculation system by inhibiting the production of inflammatory factors, reducing, or eliminating the damage to vascular endothelial cells and microvessels, and improving vascular permeability. The clarification of the mechanisms of action of the drug is conducive to the extensive clinical application of the classical formula.
