Screening of plasma biomarkers in ASA-AKI patients by proteomics. a Venn diagram depicting the number of differentially expressed proteins between the post-AKI group (0 h after surgery) vs. post-non-AKI group (0 h after surgery), as well as the post-AKI (0 h after surgery) group vs. pre-operative group (preoperative timepoint), with 32 crossed proteins identified. b List of the crossed proteins and their corresponding fold changes. c–d Volcano plots illustrating the up-regulation of S100A8, S100A9, PTX3, and CHI3L1 in ASA-AKI patients compared to non-ASA-AKI patients at postoperative 0 h (c), and preoperative measurements (d). ASA-AKI, acute type A aortic dissection surgery-associated acute kidney injury; PTX3, pentraxin 3; CHI3L1, chitinase 3-like 1
