Specialized pro-resolving lipid mediators including maresin 1 mediate resolution but the levels of these are reduced in Alzheimer's disease brain, suggesting that they constitute a novel target for the treatment of Alzheimer's disease to prevent/stop inflammation and combat disease pathology. Therefore, it is important to clarify whether they counteract the expression of genes and proteins induced by amyloid-β. With this objective, we analyzed the relevance of human monocyte–derived microglia for in vitro modeling of neuroinflammation and its resolution in the context of Alzheimer's disease and investigated the pro-resolving bioactivity of maresin 1 on amyloid-β42–induced Alzheimer's disease–like inflammation. Analysis of RNA-sequencing data and secreted proteins in supernatants from the monocyte-derived microglia showed that the monocyte-derived microglia resembled Alzheimer's disease–like neuroinflammation in human brain microglia after incubation with amyloid-β42. Maresin 1 restored homeostasis by down-regulating inflammatory pathway related gene expression induced by amyloid-β42 in monocyte-derived microglia, protection of maresin 1 against the effects of amyloid-β42 is mediated by a re-balancing of inflammatory transcriptional networks in which modulation of gene transcription in the nuclear factor-kappa B pathway plays a major part. We pinpointed molecular targets that are associated with both neuroinflammation in Alzheimer's disease and therapeutic targets by maresin 1. In conclusion, monocyte-derived microglia represent a relevant in vitro microglial model for studies on Alzheimer's disease-like inflammation and drug response for individual patients. Maresin 1 ameliorates amyloid-β42–induced changes in several genes of importance in Alzheimer's disease, highlighting its potential as a therapeutic target for Alzheimer's disease.

Objective: The objective of this study was to investigate the effects of Da-Cheng-Qi decoction (DCQD) on enteroparalysis and levels of the serum inflammatory cytokines C-C motif chemokine ligand 2 (CCL2) and interleukin-8 (IL-8) in patients with severe acute pancreatitis (SAP). Methods: A total of 48 patients diagnosed with SAP who hospitalized in First Affiliated Hospital of Henan Traditional Chinese Medicine University from May 1, 2016 to May 30, 2018 were randomly assigned to the control or treatment groups. Patients in the control group (n = 22) received conventional treatment and those in the treatment group (n = 26) received conventional treatment as well as additional DCQD for 10 days. The duration of abdominal pain and distension, the time when bowel sounds returned to normal, changes in the levels of serum amylase, lipase, C-reactive protein (CRP), CCL2 and IL-8, as well as acute physiology and chronic health evaluation (APACHE)Ⅱ scores of patients on days 1 and 10 were recorded and compared. Results: The duration of abdominal pain and distension, the time when bowel sounds returned to normal, the levels of blood amylase, lipase and CRP, and APACHE Ⅱ scores of patients in the treatment group decreased significantly compared with those of patients in the control group. Though there were no statistical differences in serum CCL2 and IL-8 concentrations on day 1 between patients in these two groups, the levels of serum CCL2 and IL-8 in the treatment group were lower than those in the control group on day 10. Conclusion: DCQD may decrease the levels of CCL2, CRP, and IL-8 in patients with SAP, quickly relieve enteroparalysis, and shorten hospitalization duration.
