Abstract |
Severe acute pancreatitis (SAP) is a common acute clinical abdomen syndrome which is characterized by pancreatic self-digestion. As one of the major complication of SAP, acute lung injury is the main reason of high mortality. The traditional Chinese medicine Qingyi pellet (QYT) has been widely used for SAP in clinic. In our study, we constructed the severe acute pancreatitis-associated lung injury (SAP-ALI) rat model and treated with QYT, then characterized the protein from the lung tissue by using a mass spectrometry-based proteomic strategy. Our results showed that, in the SAP group, 9 proteins exhibited obvious changes according to the proteomic analysis. Among the 9 proteins, 7 proteins (alpha-2-macroglobulin, Cathepsin S, ras-related protein RAP-1A, integrin beta, protein phosphatase 2A, Intercellular adhesion molecule 1 and p38) were up-regulated, and 2 proteins (adapter molecule Crk and stathmin) were down-regulated. Interestingly, the data of the QYT group showed that adapter molecule Crk and stathmin were up-regulated, but the other 7 proteins were down-regulated. The kyoto encyclopedia of genes shows that the proteins act on PI3K-AKT, chemokine signaling pathways, apoptosis, leukocyte transendothelial migration and focal adhesion. Therefore, the therapeutic effects of QYT on SAP-ALI are potentially through the additive and/or synergistic interactions of numerous components.
