Abstract
Vascular disorders, characterized by vascular endothelial dysfunction combined with inflammation, are correlated with numerous fatal diseases, such as coronavirus disease-19 and atherosclerosis. Achieving vascular normalization is an urgent problem that must be solved when treating inflammatory vascular diseases. Inspired by the vascular regulatory versatility of nitric oxide (NO) produced by endothelial nitric oxide synthase (eNOS) catalyzing l-arginine (l-Arg), the eNOS-activating effects of l-Arg, and the powerful anti-inflammatory and eNOS-replenishing effects of budesonide (BUD), we constructed a bi-prodrug minimalist nanoplatform co-loaded with BUD and l-Arg via polysialic acid (PSA) to form BUD-l-Arg@PSA. This promoted vascular normalization by simultaneously regulating vascular endothelial dysfunction and inflammation. Mediated by the special affinity between PSA and E-selectin, which is highly expressed on the surface of activated endothelial cells (ECs), BUD-l-Arg@PSA selectively accumulated in activated ECs, targeted eNOS expression and activation, and promoted NO production. Consequently, the binary synergistic regulation of the NO/eNOS signaling pathway occurred and improved vascular endothelial function. NO-induced nuclear factor-kappa B alpha inhibitor (IκBα) stabilization and BUD-induced nuclear factor-kappa B (NF-κB) response gene site occupancy achieved dual-site blockade of the NF-κB signaling pathway, thereby reducing the inflammatory response and inhibiting the infiltration of inflammation-related immune cells. In a renal ischemia-reperfusion injury mouse model, BUD-l-Arg@PSA reduced acute injury. In an atherosclerosis mouse model, BUD-l-Arg@PSA decreased atherosclerotic plaque burden and improved vasodilation. This represents a revolutionary therapeutic strategy for inflammatory vascular diseases.

Focal Adhesion Kinase Inhibitor Inhibits the Oxidative Damage Induced by Central Venous Catheter via Abolishing Focal Adhesion Kinase-Protein Kinase B Pathway Activation. BIOMED RESEARCH INTERNATIONAL 2021; 2021:6685493. [PMID: 33748278 PMCID: PMC7943296 DOI: 10.1155/2021/6685493] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/12/2020] [Revised: 02/02/2021] [Accepted: 02/07/2021] [Indexed: 11/24/2022]
Abstract
The vascular injury induced by central venous catheter (CVC) indwelling is the basis for the occurrence and development of CVC-related complications, such as phlebitis, venous thrombosis, and catheter-related infections. Focal adhesion kinase (FAK) and FAK-protein kinase B (AKT) signaling pathway are of great significance in tissue repair after trauma. Here, we investigated the role and mechanism of the FAK inhibitor (1,2,4,5-phenyltetramine tetrahydrochloride (Y15)) in oxidative damage caused by CVC. EA.hy926 cells were divided into the control group (normal control), CVCs+scratches group (the intercepted CVC segments coculturing with scratched EA.hy926 cells), and CVCs+scratches+Y15 group (Y15 was added to the cell culture supernatant with CVCs + scratches at a final concentration of 50 μmol·L−1). New Zealand rabbits were randomly divided into the control group (normal control), CVC group (CVC was inserted through the rabbit's right jugular vein to the junction of the right atrium and superior vena cava), and CVC+Y15 group (CVC was immersed in a 50 μmol·L−1 Y15 solutions before insertion). The levels of markers and proteins related to oxidative damage in cells, cell culture supernatant, serum, and external jugular vein were measured by commercial kits and western blot, respectively. We found that Y15 treatment significantly decreased ROS and MDA levels and increased cell viability, NO, and SOD levels in a time-dependent manner in rabbit serum and cell culture supernatant. In addition, Y15 effectively reduced the CVC-induced pathological changes of damaged vascular tissues. Y15 also downregulated the levels of p-FAK Tyr 397 and p-Akt Ser 473 in damaged external jugular vein and EA.hy926 cells. These findings suggest that Y15 alleviated CVC-induced oxidative damage to blood vessels by suppressing focal FAK-Akt pathway activation.

Abstract
Acute kidney injury (AKI) and chronic kidney disease (CKD) represent different stages of renal failure; thus, CKD can be regarded as a result of AKI deterioration. Previous studies have demonstrated that immune cell infiltration, oxidative stress, and metabolic mentalism can support renal fibrosis progression in AKI cases. However, the most important triggers and cell types involved in this pathological progression remain unclear. This study was conducted to shed light into the underlying cellular and molecular features of renal fibrosis progression through the analysis of three mouse whole kidney and one human single-cell RNA-sequencing datasets publicly available. According to the different causes of AKI (ischemia reperfusion injury [IRI] or cisplatin), the mouse samples were divided into the CIU [control-IRI-unilateral ureteral obstruction (UUO)] and CCU (control-cisplatin-UUO) groups. Comparisons between groups revealed eight different modules of differentially expressed genes (DEGs). A total of 1,214 genes showed the same expression pattern in both CIU and CCU groups; however, 1,816 and 1,308 genes were expressed specifically in the CCU and CIU groups, respectively. Further assessment of the DEGs according to the Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment pathway and Gene Ontology (GO) showed that T-cell activation, fatty acid metabolic process, and arachidonic acid metabolism were involved in the fibrosis progression in CIU and CCU. Single-cell RNA-sequencing data along with the collected DEGs information also revealed that the T-cell activation mainly happened in immune cells, whereas the fatty acid metabolic process and arachidonic acid metabolism occurred in tubule cells. Taken together, these findings suggest that the fibrosis process differed between the CIU and CCU stages, in which immune and tubule cells have different functions. These identified cellular and molecular features of the different stages of fibrosis progression may pave the way for exploring novel potential therapeutic strategies in the clinic.

Abstract
BACKGROUND Renal ischemia-reperfusion (I/R) injury often occurs in various clinical events, and its incidence and mortality have been increasing. OBJECTIVE To investigate the value of contrast enhanced ultrasonography (CEUS) in the monitoring of dexamethasone in the improvement of renal I/R injury in rats. METHODS Eighteen healthy male Sprague-Dawley rats were randomly divided into sham-operated, I/R, and I/R surgery plus dexamethasone treatment (Dexa) groups. In the I/R group 45-minute renal ischemia with 24 h reperfusion period was monitored. Time-intensity curve (TIC)-derived parameters, which included peak value, time to peak (TP), area under the curve (AUC), and mean transit time (MTT) were compared to the blood creatinine, urea, Caspase-1, and NLRP3 levels. RESULTS The I/R group showed an increased peak value, prolonged TP and MTT, and greater AUC (P < 0.05). The Dexa group showed shorter TP and MTT, and smaller AUC (P < 0.05). Results show that the associations between (i) TP, AUC, and MTT and (ii) creatinine, urea, Caspase-1, and NLRP3 levels were significant (P < 0.05). CONCLUSION Dexamethasone can alleviate renal I/R injury in rats, which may be related to the inhibition of NLRP3 and caspase-1. CEUS can quantitatively measure this change, in which the changes in TP, AUC and MMT values have considerable reference values.

Abstract
Background Renal ischemia-reperfusion (I/R) is directly associated with acute renal failure and can occur in conditions such as infarction caused by embolization or thrombosis, septicemia, and kidney transplantation. The process is complex, involving innate and adaptive immune responses, presence of cellular infiltrate, and production and release of cytokines and chemokines. It also triggers cell responses and release of reactive oxygen species, in addition to causing apoptosis and, in some cases, cell necrosis. Against this background, evaluation of renal tissue protection mechanisms is essential. Objectives The objective of this study was to test the M&G solution, developed in prior research, evaluating its capacity to protect the kidneys using morphometric analysis and by assaying the presence and expression of inflammatory cytokines (TNF-alpha, VEGF, HIF, and IL-8). Methods Eighteen Wistar rats were divided into three groups: Sham (S), Control (C), and Experimental (E). The S group underwent the surgical operation, but without arterial clamping. In group C, the aorta was clamped above and below the left renal artery, without infusion of the preservation solution. In group E, in addition to clamping, the aorta was punctured and M&G solution was infused continuously for 20 minutes at 15o C. Morphological analysis and immunohistochemical assessment of markers were then conducted. Results Morphological differences were identified in group S compared with groups C and E. Analysis of markers revealed reduced intensity of expression of TNF and of VEGF in group E. There were no differences in HIF or IL-8 between groups. Conclusions The M&G solution was associated with a reduction in presence and expression of TNF-alpha and a trend to reduced VEGF.

Abstract
We investigated the clinical significance of mechanical ventilation on ischemic-reperfusion injury caused by lung chest trauma as well as vascular endothelial growth factor (VEGF) expression levels in peripheral blood. Sixty-eight patients with severe chest trauma complicated with acute respiratory distress syndrome that were treated at our Tianjin Hospital from September 2013 to July 2016 were recruited. These patients were randomly and evenly divided into two groups, the research group and the control group. Thirty-four age and gender matched healthy people were selected as the normal group. Routine treatment was given to both the research and control groups, but mechanical ventilation was used in the research group. We detected pulmonary vascular resistance (PVR) and alveolar-arterial oxygen difference (AaDO2) for patients in both groups before treatment, and after treatment for 1, 3, 6 and 12 h. We also tested PMN, superoxide dismutase (SOD), malondialdehyde (MDA), NO and Ang II value 30 min before and after treatment. We used the ELISA-test to detect VEGF expression levels in peripheral blood, followed by a statistical analysis. PVR levels of different time points in the research group were significantly lower than control group after treatment. The AaDO2 value of the control group is much smaller than research group (P<0.5) after treatment for 1, 3 or 6 h. PMN count difference and MDA level in the research group is significantly lower than the control group after treatment for 30 min, but SOD and NO levels are much higher. Ang II levels of the research group in left atrial blood is significantly lower than control group (P<0.05). By comparing the hospitalization times, we found that patients in the research group have a shorter duration in hospital than the control group; differences are statistically significant (P<0.05). Additionally, compared to control group, research group VEGF expression levels in peripheral blood are significantly lower (P<0.05). Therefore, mechanical ventilation can reduce the high VEGF expression levels in serum caused by ischemic-reperfusion and can be used for clinical application.
