Ameliorative Effect of Dangguibuxue Decoction against Cyclophosphamide-Induced Heart Injury in Mice.

ABSTRACT: Dangguibuxue decoction (DBD), a kind of Chinese herbal medicine, has been widely used to treat blood deficiency disease in China. In this experiment, we studied the effects of the Dangguibuxue decoction (DBD) on the myocardial injury induced by cyclophosphamide in mice. Alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatine kinase (CK), and lactic dehydrogenase (LDH) in serum were detected by commercial kits. Total white blood cell (WBCs), platelets, and cytokines pathological changes of heart tissue were also examined. In addition, the protein levels of the NF-?B pathway were detected to reveal its mechanism. The results showed that DBD significantly decreased the levels of ALT, AST, CK, and LDH and increased WBCs in CTX-induced mice. In addition, DBD significantly alleviated pathological changes of heart tissue. DBD significantly reduced the protein expressions of NF-?B signaling pathway. In summary, DBD can be considered an effective drug to alleviate CTX-induced heart damage in mice.

Project description:Background:Sepsis-induced cardiomyopathy (SIC) is a common severe complication of sepsis that contributes to mortality. SIC is closely associated with excessive inflammatory responses, failed inflammation resolution, and apoptotic damage. Resolvin E1 (RvE1), an omega-3 polyunsaturated fatty acid (PUFA)-derived metabolite, has been reported to exert anti-inflammatory or proresolving activity in multiple animal models of inflammatory disease. However, the therapeutic potential of RvE1 in SIC remains undetermined, which was, therefore, the aim of the present study. Methods:C57BL/6J mice were randomly divided into three groups: control, lipopolysaccharide (LPS), and LPS + RvE1. Echocardiography, Western blotting (WB), quantitative real-time (QRT)-PCR, histological analyses, and flow cytometry were used to evaluate cardiac function, myocardial inflammation, and the underlying mechanisms. Results:The RvE1-injected group showed improved left ventricular (LV) function and reduced serum lactate dehydrogenase (LDH) and creatine kinase myocardial bound (CK-MB) levels. Compared to LPS treatment alone, RvE1 treatment inhibited the infiltration of neutrophils and macrophages into the heart and spleen and suppressed the secretion of pro-inflammatory cytokines, including interleukin (IL)-1?, IL-6, and monocyte chemoattractant protein (MCP)-1, in the heart. We also observed that the activation of the mitogen-activated protein kinase (MAPK) and nuclear factor (NF)-?B signaling pathways was blocked by RvE1 treatment, and this inhibition contributed to the improvement in the inflammatory response induced by LPS. RvE1 inhibited LPS-induced M1 macrophage polarization and promoted macrophage polarization toward the M2-like phenotype in both the heart and spleen. In addition, LPS administration dysregulated cyclooxygenase (COX) and lipoxygenase (LOX) in the heart, which were rectified by RvE1 treatment. RvE1 also reduced myocardial apoptosis rate in response to LPS-induced heart injury. Conclusion:RvE1 protects the heart against SIC possibly through the inhibition of the MAPK and NF-?B inflammatory signaling pathways, modulation of macrophage polarization, and reduction in myocardial apoptosis. RvE1 may be a novel lipid mediator for the treatment of SIC.
