RESUMO
Accumulating evidence has noted the circRNA-microRNA- (circRNA-miRNA-) mRNA competing endogenous RNA (ceRNA) regulatory network in disease development and progression. The current study explored the ceRNA network in acute traumatic coagulopathy (ATC). Potential ATC-related genes were screened, and upstream miRNAs and circRNAs of VWF (the candidate target) were assayed through database searching and high-throughput sequencing technology. circ_0001274/miR-143-3p/VWF ceRNA regulatory network was constructed and validated. The expression of circ_0001274/miR-143-3p/VWF was determined in the peripheral blood samples from ATC patients and ATC mouse models. Online database and circRNA sequencing analysis results identified VWF as a key gene in ATC as supported by assays and that VWF was lowly expressed in ATC patients and mice. Further experiments demonstrated that miR-143-3p could target and inhibit VWF, and circ_0001274 could competitively sponge miR-143-3p. Functionally, circ_0001274 could competitively sequester miR-143-3p to upregulate VWF expression, potentially improving ATC. Our study highlights the critical role of circ_0001274/miR-143-3p/VWF axis in improving ATC.

PURPOSE: The objective of the present study is to provide a comprehensive review of the literature on associated outcomes of angioembolization in blunt abdominal solid organ traumas. METHODS: The databases of Medline, Embase, and Cochrane Library were explored until 24 September 2021. All studies with data on the efficacy or safety of angioembolization in patients suffering from hemodynamically unstable blunt abdominal solid organ trauma were included. The primary outcomes were clinical success rate and mortality. Pooled event rates were calculated using a double arcsine transformation to stabilize the variance of the original proportion. RESULTS: In total, 13 reports of 12 studies were included in the systematic review. According to the current meta-analysis, the angioembolization for blunt abdominal solid organ trauma in hemodynamically unstable patients had a high clinical success rate [0.97 (95% CI 0.93-0.99)] and low mortality [0.03 (95% CI 0.01-0.07)]. Furthermore, no statistically significant difference was found between the various injured solid organs for either of these parameters. In addition, the technique-associated adverse events were seldom and tolerable. CONCLUSIONS: For blunt abdominal solid organ trauma in hemodynamically unstable patients, this review shows that angioembolization exhibited a high clinical success rate, low mortality, and tolerable technique-related adverse events. Furthermore, the top possible indication for angioembolization in hemodynamically unstable patients is an individual who responds to rapid fluid resuscitation. However, high-quality and large-scale trials are needed to confirm these results and determine the selection criteria for appropriate patients in this setting.

Competitive endogenous RNA (ceRNA) networks play crucial roles in multiple biological processes and development of diseases. They might serve as diagnostic and prognosis markers as well as therapeutic targets. The purpose of this study was to identify a novel ceRNA network involving KCNQ1OT1, hsa-miR-24-3p, and VWF in acute traumatic coagulopathy (ATC) based on databases search. We searched the CTD, GeneCards, and PharmGKB databases for ATC-related target genes using Coagulopathy as a keyword. Upstream miRNAs and lncRNAs of the candidate target VWF were then explored using the miRWalk, microT, TargetScan, RNA22 and Tarbase, and DIANA-LncBase and Starbase databases, respectively. A KCNQ1OT1-hsa-miR-24-3p-VWF ceRNA network was constructed by R "ggalluvial" package. Interaction between KCNQ1OT1, hsa-miR-24-3p, and VWF was examined, and their expression was quantified in the peripheral blood samples from 30 ATC patients and liver tissues of ATC rat models. Forty-one ATC-related target genes were identified following data retrieval from publicly available databases, of which VWF was selected as the target and used for the subsequent analysis. KCNQ1OT1 and hsa-miR-24-3p were confirmed to be the key upstream regulatory factors of VWF. KCNQ1OT1-hsa-miR-24-3p-VWF coexpression regulatory network was constructed where KCNQ1OT1 competitively bound to hsa-miR-24-3p and attenuated its binding to VWF. Both the liver tissues of ATC rats and peripheral blood samples from ATC patients showed increased hsa-miR-24-3p expression and decreased VWF and KCNQ1OT1 expression. Collectively, we described the KCNQ1OT1-hsa-miR-24-3p-VWF ceRNA network in the development of ATC. We propose a new ceRNA that could help in the diagnosis and treatment of ATC.
