Biomed Pharmacother 2024; 179:117345. [PMID: 39208667 DOI: 10.1016/j.biopha.2024.117345] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2024] [Revised: 08/08/2024] [Accepted: 08/22/2024] [Indexed: 09/04/2024] Open
Abstract
This study investigates the protective effects of propofol on the myocardium by inhibiting the expression of SLC16A13 through in vivo animal experiments, while also exploring its mechanism in ferroptosis to provide new strategies for preventing perioperative myocardial ischemia-reperfusion injury. We randomly divided 30 rats into three groups (n=10 each): sham surgery group, ischemia-reperfusion (I/R) group, and propofol pretreatment group. The results showed that compared with the sham surgery group, the I/R group had a significant decrease in cardiac function and an increase in infarct size. Propofol pretreatment effectively alleviated the damage caused by ischemia-reperfusion (I/R). In the next phase of the study, we administered the PPARα agonist GW7647 to artificially increase the expression of SLC16A13. Fifty rats were randomly divided into five groups (n=10 each), with the GW7647 pretreatment group and propofol+GW7647 pretreatment group added based on the previous three groups. Afterwards, we validated the in vivo results using H9C2 and further explored the mechanism by which propofol inhibits ferroptosis. The study found that L-lactic acid in myocardial tissue of the GW7647 group was further increased compared to the I/R group, and the degree of ferroptosis was aggravated. In addition, upregulation of SLC16A13 significantly inhibited the phosphorylation of AMPK, weakened the protective mechanism of AMPK, and exacerbated cardiac damage. However, propofol pretreatment can effectively inhibit the expression of SLC16A13, maintain normal myocardial cell morphology, and protect cardiac function. These results indicate that propofol inhibits the expression of SLC16A13, alleviates myocardial cell ferroptosis via the AMPK/GPX4 pathway, and reverses damage caused by myocardial ischemia-reperfusion.

Construction of preclinical evidence for propofol in the treatment of reperfusion injury after acute myocardial infarction: A systematic review and meta-analysis. Biomed Pharmacother 2024; 174:116629. [PMID: 38640712 DOI: 10.1016/j.biopha.2024.116629] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2024] [Revised: 04/04/2024] [Accepted: 04/17/2024] [Indexed: 04/21/2024] Open
Abstract
Propofol, a commonly used intravenous anesthetic, has demonstrated potential in protecting against myocardial ischemia/reperfusion injury (MIRI) based on preclinical animal studies. However, the clinical benefits of propofol in this context are subject to debate. We conducted a systematic search across eight databases to identify all relevant animal studies investigating the preventive effects of propofol on MIRI until October 30, 2023. We assessed the methodological quality of the included studies using SYRCLE's bias risk tool. Statistical analysis was performed using STATA 15.1. The primary outcome measures analyzed in this study were myocardial infarct size (IS) and myocardial injury biomarkers. This study presents a comprehensive analysis of 48 relevant animal studies investigating propofol's preventive effects on MIRI. Propofol administration demonstrated a reduction in myocardial IS and decreased levels of myocardial injury biomarkers (CK-MB, LDH, cTnI). Moreover, propofol improved myocardial function parameters (+dp/dtmax, -dP/dtmax, LVEF, LVFS), exhibited favorable effects on inflammatory markers (IL-6, TNF-α) and oxidative stress markers (SOD, MDA), and reduced myocardial cell apoptotic index (AI). These findings suggest propofol exerts cardioprotective effects by reducing myocardial injury, decreasing infarct size, and improving heart function. However, the absence of animal models that accurately represent comorbidities such as aging and hypertension, as well as inconsistent administration methods that align with clinical practice, may hinder its clinical translation. Further robust investigations are required to validate these findings, elucidate the underlying mechanisms of propofol, and facilitate its potential translation into clinical practice.

Abstract
Preeclampsia (PE) belongs to hypertensive disorder complicating pregnancy, which is a serious obstetric complication. Propofol is a new type of fast and short-acting general anesthetic, which has also been demonstrated to promote the cell growth recently. Therefore, this study was carried out to explore the effects of propofol on the cell growth, migration and invasion in the HTR-8/SVneo cells. The cell biological behaviors were analyzed using CCK-8, EdU, transwell assays. The relationship between METTL3 and ZEB2 was confirmed by RIP assay. Western blot and RT-qPCR assays were carried out to detect the protein and mRNA levels. The results showed that propofol enhanced the cell viability, proliferation, migration and invasion of the HTR-8/SVneo cells. Besides, METTL3 overexpression neutralized the propofol role. Furthermore, METTL3 overexpression elevated the m6A levels of ZEB2 and decreased the mRNA levels and stability of ZEB2. ZEB2 overexpression neutralized the role of METTL3 in the propofol treated HTR-8/SVneo cells. In conclusion, this study demonstrated the effects of propofol on promoting the cell growth, migration and invasion of HTR-8/SVneo cells. Mechanistically, propofol indirectly regulated ZEB2 expression by targeting METTL3 mediated m6A methylation modification.

[PMID: 37647434 PMCID: PMC10408373 DOI: 10.1002/iid3.952] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2023] [Revised: 07/05/2023] [Accepted: 07/08/2023] [Indexed: 09/01/2023] Open
Abstract
BACKGROUND Myocardial injury is the main manifestation of cardiovascular diseases, and previous studies have shown that propofol (PPF) regulates myocardial injury. However, the mechanism of PPF in regulating myocardial injury remains to be further explored. This work aims to analyze the effects of PPF on human cardiomyocyte injury and the underlying mechanism. METHODS The regulatory and functional role of PPF and circAPBB2 in human cardiomyocyte injury were analyzed using an in vitro hypoxia/reoxygenation (H/R) cell model, which was established by treating human cardiomyocytes (AC16 cells) with H/R. The study evaluated AC16 cell injury by analyzing cytotoxicity, oxidative stress, inflammation and apoptosis of H/R-induced AC16 cells. Quantitative real-time polymerase chain reaction was performed to detect circAPBB2, miR-18a-5p and dual specificity phosphatase 14 (DUSP14) expression. Protein expression was analyzed by Western blot analysis assay. Dual-luciferase reporter assay, RNA pull-down assay and RNA immunoprecipitation assay were performed to identify the associations among circAPBB2, miR-18a-5p and DUSP14. Cytotoxicity was investigated by cell counting kit-8 assay and lactate dehydrogenase activity detection kit. Oxidative stress was evaluated by cellular reactive oxygen species assay kit and superoxide dismutase activity assay kit. The production of tumor necrosis factor-α and interleukin-1β was evaluated by enzyme-linked immunosorbent assays. RESULTS The expression of circAPBB2 and DUSP14 was significantly decreased, while miR-18a-5p was increased in H/R-induced AC16 cells when compared with controls. H/R treatment-induced cytotoxicity, oxidative stress, inflammation and cell apoptosis were attenuated after circAPBB2 overexpression or PPF treatment, whereas these effects were restored by increasing miR-18a-5p expression. PPF treatment improved the inhibitory effect of ectopic circAPBB2 expression on H/R-induced cell injury. MiR-18a-5p silencing ameliorated H/R-induced AC16 damage by interacting with DUSP14. Mechanically, circAPBB2 acted as a miR-18a-5p sponge, and miR-18a-5p targeted DUSP14 in AC16 cells. CONCLUSION PPF synergized with circAPBB2 to protect AC16 cells against H/R-induced oxidative stress, inflammation and apoptosis through the miR-18a-5p/DUSP14 pathway.

Abstract
In this study, we intend to explore the potential function of l-ascorbic acid in hypoxia-reoxygenation (H/R)-induced damage of CMECs and its related molecular mechanism. With different concentrations of l-ascorbic acid treatment, the proliferation, migration, inflammation and autophagy of cardiac microvascular endothelial cells (CMECs) were determined by several biological experiments. Si-HMGB1 transfection was used to reduce HMGB1 expression and to detect the function of HMGB1 in H/R-induced damage of CMECs. Under H/R condition, the proliferation and migration abilities of CMECs were reduced, and the inflammation and autophagy of CMECs were increased. Whereas, after l-ascorbic acid treatment, the reduction in the proliferation and migration of CMECs, as well as the increase in the inflammation and autophagy of CMECs induced by H/R were reversely altered. HMGB1 was confirmed as a specific target of l-ascorbic acid, and si-HMGB1 treatment strengthened the beneficial effect of l-ascorbic acid on H/R-induced damage of CMECs, followed by further reduction in the proliferation and migration abilities of CMECs, as well as the increase in the inflammation and autophagy of CMECs. Few studies have reported the function of l-ascorbic acid in myocardial ischemia on CMECs, but our experimental data showed that l-ascorbic acid treatment could ameliorate the H/R-induced damage of CMECs by regulating HMGB1 expression.

Abstract
Ischemia-reperfusion (I/R) is a common pathological phenomenon that occurs in numerous organs and diseases. It generally results from secondary damage caused by the recovery of blood flow and reoxygenation, followed by ischemia of organ tissues, which is often accompanied by severe cellular damage and death. Currently, effective treatments for I/R injury (IRI) are limited. Ferroptosis, a new type of regulated cell death (RCD), is characterized by iron overload and iron-dependent lipid peroxidation. Mounting evidence has indicated a close relationship between ferroptosis and IRI. Ferroptosis plays a significantly detrimental role in the progression of IRI, and targeting ferroptosis may be a promising approach for treatment of IRI. Considering the substantial progress made in the study of ferroptosis in IRI, in this review, we summarize the pathological mechanisms and therapeutic targets of ferroptosis in IRI.

Front Pharmacol 2022; 13:841410. [PMID: 35370724 PMCID: PMC8966655 DOI: 10.3389/fphar.2022.841410] [Citation(s) in RCA: 25] [Impact Index Per Article: 12.5] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2021] [Accepted: 02/21/2022] [Indexed: 12/19/2022] Open
Abstract
The molecular mechanism underlying the protective role of propofol against myocardial ischemia/reperfusion (I/R) injury remains poorly understood. Previous studies have shown that ferroptosis is an imperative pathological process in myocardial I/R injury. We hypothesized that propofol prevents myocardial I/R injury by inhibiting ferroptosis via the AKT/p53 signaling pathway. The ferroptosis-inducing agent erastin (E) and AKT inhibitor MK2206 (MK) were used to investigate the role of propofol in myocardial I/R injury. H9C2 cells treated without any reagents, erastin for 24 h, propofol for 1 h before adding erastin were assigned as the control (C), E, and E + P group, respectively. Cell viability, reactive oxygen species (ROS), and the expression of antioxidant enzymes, including ferritin heavy chain 1 (FTH1), cysteine/glutamate transporter (XCT), and glutathione peroxidase 4 (GPX4) in H9C2 cells. Rat hearts from the I/R + P or I/R groups were treated with or without propofol for 20 min before stopping perfusion for 30 min and reperfusion for 60 min. Rat hearts from the I/R + P + MK or I/R + MK groups were treated with or without propofol for 20 min, with a 10-min treatment of MK2206 before stopping perfusion. Myocardial histopathology, mitochondrial structure, iron levels, and antioxidant enzymes expression were assessed. Our results demonstrated that erastin increased H9C2 cell mortality and reduced the expression of antioxidant enzymes. I/R, which reduced the expression of antioxidant enzymes and increased iron or p53 (p < 0.05), boosted myocardium pathological and mitochondrion damage. Propofol inhibited these changes; however, the effects of propofol on I/R injury were antagonized by MK (p < 0.05). In addition, AKT siRNA inhibited the propofol-induced expression of antioxidant enzymes (p < 0.05). Our findings confirm that propofol protects myocardium from I/R injury by inhibiting ferroptosis via the AKT/p53 signal pathway.

Abstract
Myocardial ischemia/reperfusion (MI/RI) syndrome is one of the leading causes of mortality and disability. Propofol postconditioning is known to improve myocardial ischemia/reperfusion injury (MI/RI). The present study aimed to explore the mechanism of propofol postconditioning in diabetic MI/RI. Diabetic MI/RI rat models were established and the rats were treated via propofol postconditioning. Staining with 2,3,5-triphenyl-2H-tetrazolium chloride, H&E staining, TUNEL staining and ELISA were applied to detect infarct size, pathological changes, apoptosis and oxidative stress-related factor and apoptotic factor levels, respectively. Subsequently, the effect of propofol on H9C2 cells was also assessed using the Cell Counting Kit-8 assay. High-glucose hypoxia/reperfusion (H/R) models of H9C2 cardiomyocytes were established. miR-200c-3p overexpression or AdipoR2 silencing combined with propofol postconditioning was performed in H/R-induced H9C2 cells and STAT3 protein expression levels were determined. Propofol postconditioning significantly reduced myocardial infarct size, oxidative stress and apoptosis in diabetic MI/RI models. Furthermore, propofol postconditioning significantly reduced the oxidative stress and apoptosis of H9C2 cells in high-glucose H/R models. Propofol postconditioning also significantly downregulated miR-200c-3p expression levels and promoted AdipoR2 expression levels. miR-200c-3p overexpression or AdipoR2 downregulation significantly reversed the effects of propofol postconditioning on its antioxidation and anti-apoptotic effects in H9C2 cells and on decreasing STAT3 phosphorylation levels. Together, the results of the present study demonstrated that propofol postconditioning inhibited miR-200c-3p, upregulated AdipoR2 and activated the STAT3 signaling pathway, thus alleviating diabetic MI/RI and therefore highlighting its potential as a treatment of diabetic MI/RI.

Abstract
Anesthetics have been widely used in surgery and found to suppress inflammatory injury and affect the outcomes of the surgery and diseases. In contrast, anesthetics are also found to induce neuronal injury and inflammation. However, the immune-modulation mechanism of anesthetics is still not clear. Recent studies have shown that the immune-modulation of anesthetics is associated with the regulation of toll-like receptor (TLR)-mediated signaling. Moreover, the regulation of anesthetics in TLR signaling is related to modulations of non-coding RNAs (nc RNAs). Consistently, nc RNAs are mainly divided into micro RNAs (miRs) and long non-coding RNAs (lnc RNAs), which have been found to exert regulatory effects on the immune system. In this review, we summarize the immunomodulatory functions of the widely used anesthetic agents, which are associated with regulation of TLR signaling. In addition, we also focus on the roles of nc RNAs induced by anesthetics in regulations of TLR signaling.

Abstract
Propofol has been revealed to protect cardiomyocytes against myocardial ischemia injury, although the underlying mechanism remains incompletely understood. H9C2 cells were used to generate a hypoxia/reoxygenation (H/R) in vitro model for the present study. Reverse transcription-quantitative PCR and western blotting were performed to measure the expression levels of microRNA (miR)-449a and nuclear receptor subfamily 4 group A member 2 (NR4A2). The CCK-8, BrdU, EdU, and caspase-3 activity assays and western blot analysis were employed to detect cell viability, proliferation, and apoptosis. The target relationship between miR-449a and NR4A2 was verified through dual-luciferase reporter assays. The results confirmed that exposure of the cells to H/R resulted in severe cell injury. However, the presence of propofol improved cell activity by promoting cell viability and proliferation and inhibiting cell apoptosis. The beneficial effect of propofol on H/R-mediated injury could be abrogated by the inhibition of NR4A2 mediated by miR-449a. Thus, the present study demonstrated that propofol counteracted cardiomyocyte H/R injury by inhibiting miR-449a to upregulate NR4A2.

[PMID: 34383354 DOI: 10.1002/jbt.22880] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2020] [Revised: 06/06/2021] [Accepted: 07/29/2021] [Indexed: 01/24/2023]
Abstract
Previous studies have shown that propofol (PPF) plays a protective role in ischemia-reperfusion (I/R) in multiple organs and tissues. This study was aimed to explore the mechanism of PPF in ameliorating myocardial ischemia-reperfusion injury (MIRI). MIRI model was established with Sprague-Dawley rats, and PPF pretreatment was performed before reperfusion. Creatine kinase isoform (CK-MB), lactate dehydrogenase (LDH), and hematoxylin and eosin stain were used to evaluate the severity of MIRI. H9c2 cells were treated with hypoxia/reoxygenation (H/R) to simulate I/R injury in vitro. Real-time quantitative polymerase chain reaction (qPCR) was employed to assess MALAT1 and microRNA (miR)-206 expressions. Autophagy-related 3 (ATG3), LC3BⅡ/LC3BⅠ, and Beclin-1 expression were examined by western blot. Apoptosis was monitored using flow cytometry. Interaction between MALAT1 and miR-206 was determined by bioinformatics analysis, dual-luciferase reporter gene assay, RIP assay, and RNA pull-down assay. PPF pretreatment remarkably reduced CK-MB level, LDH level, myocardial infarct size, and LC3BⅡ/LC3BⅠ ratio and Beclin-1 expression in the rats with MIRI, and repressed the apoptosis of H9c2 cells exposed to H/R. PPF pretreatment markedly suppressed MALAT1 expression and enhanced miR-206 expression in both in vivo and in vitro models. MiR-206 was identified as a target of MALAT1 in cardiomyocytes, and MALAT1 could increase the expression of ATG3. Additionally, the upregulation of MALAT1 partially reversed the protective effect of PPF on cardiomyocytes in vitro. PPF modulated MALAT1/miR-206/ATG3 axis to protect cardiomyocytes against I/R injury.

Overexpression of miR-1298 attenuates myocardial ischemia-reperfusion injury by targeting PP2A. J Thromb Thrombolysis 2021; 53:136-148.

Abstract
Previous studies reported that microRNA-1298 was abnormally expressed in the myocardium of rat hearts after hypoxia/normoxia injury. This study aims to investigate the function and specific mechanism of miR-1298 in myocardial ischemia/reperfusion (IR) injury. Neonatal rat cardiomyocytes (NRCMs) were isolated from neonatal rat hearts and subjected to oxygen/glucose deprivation/reperfusion (OGD/R) to induce I/R injury. The rat model with I/R injury was induced by ligating the proximal left anterior descending artery (LAD). MiR-1298 expression was detected by qRT-PCR. The levels of PP2A, Bcl-2, Bax, and AMPK signaling members (p-AMPK, p-GSK3β) was detected by Western blot. Cell apoptosis was evaluated by TUNEL staining assay and flow cytometry. The infarct size of rat hearts was assessed by TTC staining assay. Premature and mature MiR-1298 were significantly downregulated while PP2A was significantly upregulated during I/R injury both in vitro and in vivo. The prediction of Starbase suggested that PP2A was a potential target of miR-1298. MiR-1298 overexpression significantly reduced cardiomyocyte apoptosis in vitro, and its protective effect was obviously attenuated by PP2A overexpression. Luciferase reporter assay showed that miR-1298 targeted PP2A directly. In addition, miR-1298 overexpression significantly reduced infarct size and cardiomyocyte apoptosis in the hearts of rats received with I/R injury in vivo. Moreover, miR-1298 overexpression significantly elevated the levels of Bcl-2 and AMPK signaling members (p-AMPK, p-GSK3β) while decreased Bax level, and these effects were partially reversed by PP2A overexpression. MiR-1298 participated in myocardial I/R injury by targeting the PP2A/AMPK/GSK3β signaling pathway, suggesting that miR-1298 might be a potential therapeutic target for myocardial I/R injury.

Synapse 2021; 75:e22219. [PMID: 34269482 DOI: 10.1002/syn.22219] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2021] [Revised: 07/08/2021] [Accepted: 07/13/2021] [Indexed: 12/16/2022]
Abstract
Chronic constriction injury (CCI) of the sciatic nerve was used to establish neuropathic pain (NP) models in rats. CCI rats were then treated with propofol (Pro) and their paw withdrawal mechanical threshold (PWMT) and paw withdrawal thermal latency (PWTL) were measured. In addition, the expression patterns of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and IL-10 were detected. CCI rats treated with propofol were further injected with antagomiR-140-3p to verify the role of miR-140-3p in propofol's analgesic actions. In addition to confirming the relationship between miR-140-3p and JAG1, the expression patterns of JAG1 itself were detected. Propofol-treated CCI rats were also injected with Ad-JAG1 (adenovirus-packaged JAG1 overexpression vector and Ad-NC) to test the role of JAG1 in propofol's analgesic mechanism of action. Finally, the levels of JAG1 and Notch pathway-related proteins were detected RESULTS: Propofol was found to alleviate NP, including thermal hyperalgesia and mechanical pain threshold. Propofol could also ameliorate neuroinflammation by up-regulating the expression of IL-10 and inhibiting the release of TNF-α and IL-1β. Mechanically, propofol enhanced the amount of miR-140-3p in CCI rats via the regulation of JAG1. Down-regulation of miR-140-3p, or up-regulation of JAG1, could reduce the protective effect of propofol against NP. Propofol inhibited the activation of Notch signaling via miR-140-3p/JAG1 to realize its analgesic effect CONCLUSION: Our findings indicated that propofol inhibits inflammatory responses and the Notch signaling pathway via miR-140-3p/JAG1 to alleviate NP. These data provide evidence to support a potential clinical therapy for NP.

Abstract
Ischemic stroke still remains a therapeutic challenge due to its complex pathogenesis and implications. By screening biomarkers in the peripheral blood of ischemic stroke patients, miR-451 was identified as a differentially expressed miRNA along the disease course of ischemic stroke. To investigate the role of miR-451, middle cerebral artery occlusion (MCAO) was performed as an ischemic stroke model in mice. Intracerebroventricular administration of miR-451 mimic in the MCAO mice significantly decreased infarct size, while miR-451 inhibitor significantly increased infarct size. To understand the molecular mechanism of the protective effect of miR-451, Phd3 (also Egln3) was validated as a new miR-451 target. Either fewer or more Phd3-positive cells were observed in brain sections from mice receiving miR-451 mimic or inhibitor, respectively. In addition, the levels of p53 (a known Phd3 target) were significantly downregulated when the levels of Phd3 were reduced, suggesting its participation in reducing apoptosis after the miR-451 administration. Indeed, reduced apoptosis upon miR-451 mimic administration was detected by TUNEL staining. In conclusion, this study demonstrated a new protective role of miR-451 in cerebral ischemia and identified Phd3 as a novel miR-451 target, linking the mechanism to the involvement of p53 in the regulation of apoptosis during the pathogenesis of ischemic stroke.

Abstract
Both hydrogen peroxide (H2O2, H) and ischemia/reperfusion (I/R) can damage cardiomyocytes, which was inhibited by propofol (P). The present research was designed to examine whether propofol can reduce myocardial I/R injury by activating protein kinase C (PKC)/nuclear factor erythroid-2-related factor 2 (NRF2) pathway in H9C2 cells and rat Langendorff models. H9C2 cells were disposed of no reagents (C), H2O2 for 24 h (H), propofol for 1 h before H2O2 (H+P), and chelerythrine (CHE, PKC inhibitor) for 1 h before propofol and H2O2 (H+P+CHE). N = 3. The PKC gene of H9C2 was knocked down by siRNA and overexpressed by phorbol 12-myristate 13-acetate (PMA, PKC agonist). The cell viability and the expressions of PKC, NRF2, or heme oxygenase-1(HO-1) were evaluated. Propofol significantly reduced H9C2 cell mortality induced by H2O2, and significantly increased NRF2 nuclear location and HO-1 expression, which were restrained by siRNA knockout of PKC and promoted by PMA. Rat hearts were treated with KrebsHenseleit solution for 120 min (C), with (I/R+P) or without (I/R) propofol for 20 min before stopping perfusion for 30 min and reperfusion for 60 min, and CHE for 10 min before treated with propofol. N = 6. The levels of lactate dehydrogenase (LDH), superoxide dismutase (SOD), and creatine kinase-MB (CK-MB) in perfusion fluid and antioxidant enzymes in the myocardium were assessed. I/R, which increased LDH and CK-MB expression and reduced SOD expression, boosted the pathological damage and infarcts of the myocardium after reperfusion. However, propofol restrained all these effects, an activity that was antagonized by CHE. The results suggest that propofol pretreatment protects against I/R injury by activating of PKC/NRF2 pathway.

Abstract
The morbidity and mortality of myocardial ischemia-reperfusion injury (MIRI) have increased in modern society. Noncoding RNAs (ncRNAs), including lncRNAs, circRNAs, piRNAs and miRNAs, have been reported in a variety of studies to be involved in pathological initiation and developments of MIRI. Hence this review focuses on the current research regarding these ncRNAs in MIRI. We comprehensively introduce the important features of lncRNAs, circRNAs, piRNA and miRNAs and then summarize the published studies of ncRNAs in MIRI. A clarification of lncRNA-miRNA-mRNA, lncRNA-transcription factor-mRNA and circRNA-miRNA-mRNA axes in MIRI follows, to further elucidate the crucial roles of ncRNAs in MIRI. Bioinformatics analysis has revealed the biological correlation of mRNAs with MIRI. We provide a comprehensive perspective for the roles of these ncRNAs and their related networks in MIRI, providing a theoretical basis for preclinical and clinical studies on ncRNA-based gene therapy for MIRI treatment.

Abstract
Background Propofol (PPF) ameliorates ischemia/reperfusion (I/R) injury in multiple organs by reducing apoptosis and release of pro-inflammatory cytokines. This study aims to explore the mechanism of PPF in attenuating myocardial ischemia-reperfusion injury (MIRI). Materials and Methods Rat MIRI model was established, and PPF pre-treatment was performed 10 min before I/R. H9c2 cardiomyocytes treated with hypoxia/reoxygenation (H/R) were used to establish an in vitro model. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to evaluate HOTAIR and miR-17-5p expression levels. Flow cytometry was employed to detect the apoptosis of H9c2 cells. The interaction between HOTAIR and miR-17-5p was determined by bioinformatics analysis, luciferase reporter gene analysis, and RNA immunoprecipitation experiments. STAT3 and p-STAT3 expressions were detected by Western blot. Results PPF pre-treatment significantly reduced creatine kinase isoenzyme (CK-MB) and serum lactate dehydrogenase (LDH) levels in the serum of the rats with MIRI. PPF pre-treatment remarkably up-regulated HOTAIR expression and down-regulated miR-17-5p expression in both in vivo and in vitro models. HOTAIR adsorbed miR-17-5p to repress the expression of miR-17-5p. PPF pre-treatment markedly inhibited cardiomyocyte apoptosis induced by I/R or H/R. HOTAIR knockdown could partially reverse the protective effects of PPF on MIRI. HOTAIR could activate STAT3 signaling via repressing miR-17-5p expression. Conclusion PPF protects the MIRI by modulating the HOTAIR/miR-17-5p/STAT3 axis.

Abstract
The aim of pharmacological conditioning is to protect the heart against myocardial ischemia-reperfusion (I/R) injury and its consequences. There is extensive literature that reports a multitude of different cardioprotective signaling molecules and mechanisms in diverse experimental protocols. Several pharmacological agents have been evaluated in terms of myocardial I/R injury. While results from experimental studies are immensely encouraging, translation into the clinical setting remains unsatisfactory. This narrative review wants to focus on two aspects: (1) give a comprehensive update on new developments of pharmacological conditioning in the experimental setting concentrating on recent literature of the last two years and (2) briefly summarize clinical evidence of these cardioprotective substances in the perioperative setting highlighting their clinical implications. By directly opposing each pharmacological agent regarding its recent experimental knowledge and most important available clinical data, a clear overview is given demonstrating the remaining gap between basic research and clinical practice. Finally, future perspectives are given on how we might overcome the limited translatability in the field of pharmacological conditioning.

Abstract
Hintergrund Ziel der perioperativen Kardioprotektion ist es, die Auswirkungen eines Ischämie- und Reperfusionsschadens zu minimieren. Aus anästhesiologischer Sicht spielt dieser Aspekt insbesondere in der Herzchirurgie bei Patienten mit Einsatz der Herz-Lungen-Maschine, aber auch allgemein bei längerfristigen hypotensiven Phasen oder perioperativen ischämischen Ereignissen im nichtkardiochirurgischen Setting eine wichtige Rolle. Im Laufe der letzten Jahre konnten diverse pharmakologische sowie nichtpharmakologische Strategien der Kardioprotektion identifiziert werden. Die Ergebnisse von Studien an isoliertem Gewebe sowie von tierexperimentellen In-vivo-Studien sind vielversprechend. Eine Translation dieser kardioprotektiven Strategien in die klinische Praxis ist bislang jedoch nicht gelungen. Große klinische Studien konnten keine signifikante Verbesserung des Outcome der Patienten zeigen. Ziel der Arbeit Dieser Übersichtsartikel gibt einen Überblick über die aktuelle experimentelle Evidenz pharmakologischer und nichtpharmakologischer Kardioprotektion. Außerdem sollen mögliche Gründe für die limitierte Translation diskutiert werden. Schließlich werden Möglichkeiten aufgezeigt, wie der Schritt „from bench to bedside“ in Zukunft doch noch gelingen könnte. Material und Methoden Narrative Übersichtsarbeit. Ergebnisse und Diskussion Trotz der vielversprechenden präklinischen experimentellen Ansätze zum Thema Kardioprotektion besteht nach wie vor eine große Diskrepanz zu den Ergebnissen aus großen klinischen Studien in der perioperativen Phase. Mögliche Gründe für die limitierte Translation könnten insbesondere Komorbiditäten und Komedikationen, die Wahl des Anästhesieverfahrens, aber auch die Wahl des Studiendesigns sein. Eine sorgfältige Studienplanung mit Berücksichtigung der genannten Probleme sowie ein simultaner Einsatz mehrerer kardioprotektiver Strategien mit dem Ziel eines additiven bzw. synergistischen Effekts stellen mögliche Ansätze für die Zukunft dar.

Abstract
Myocardial ischemia/reperfusion (I/R) injury could lead to severe cardiovascular ischemic disease, including myocardial infarction and contractile dysfunction. Remifentanil demonstrated protective effect on myocardial I/R injury. The underlying pathophysiological mechanism was then investigated in this study. In the current study, primary cardiomyocytes were isolated from rats, and then preconditioned with remifentanil. Rats, tail vein injected with miR-205 antagomir, were subjected to infusion of remifentanil, and then subjected to regional ischemia followed by reperfusion. The results demonstrated that cell viability of hypoxia/reoxygenation-induced cardiomyocytes was increased post remifentanil, while the apoptosis was decreased accompanied with reduced cleaved caspase-3 expression. Hypoxia/reoxygenation treatment increased miR-205 and decreased PINK1 (PTEN induced putative kinase 1) expression. However, preconditioning with remifentanil reduced miR-205 and enhanced PINK1. Moreover, over-expression of miR-205 decreased PINK1 expression and counteracted the effects of remifentanil-induced increase of cell viability and decrease of cell apoptosis in hypoxia/reoxygenation-induced cardiomyocytes. Injection with miR-205 antagomir improved remifentanil-induced decrease of infarct size and LDH (lactic acid dehydrogenase) activity in rat model with I/R injury. In conclusion, miR-205 might participate in the protective effect of remifentanil in rat myocardial I/R injury via regulation of PINK1, providing a potential target for amelioration of cardiovascular ischemic disease.

Abstract
Cardioprotection encompasses a variety of strategies protecting the heart against myocardial injury that occurs during and after inadequate blood supply to the heart during myocardial infarction. While restoring reperfusion is crucial for salvaging myocardium from further damage, paradoxically, it itself accounts for additional cell death-a phenomenon named ischemia/reperfusion injury. Therefore, therapeutic strategies are necessary to render the heart protected against myocardial infarction. Ischemic pre- and postconditioning, by short periods of sublethal cardiac ischemia and reperfusion, are still the strongest mechanisms to achieve cardioprotection. However, it is highly impractical and far too invasive for clinical use. Fortunately, it can be mimicked pharmacologically, for example, by volatile anesthetics, noble gases, opioids, propofol, dexmedetomidine, and phosphodiesterase inhibitors. These substances are all routinely used in the clinical setting and seem promising candidates for successful translation of cardioprotection from experimental protocols to clinical trials. This review presents the fundamental mechanisms of conditioning strategies and provides an overview of the most recent and relevant findings on different concepts achieving cardioprotection in the experimental setting, specifically emphasizing pharmacological approaches in the perioperative context.

Abstract
The activation of pyroptosis is an important feature of renal ischemia/reperfusion (rI/R)-induced acute lung injury (ALI). Propofol, a general anesthetic, is known to inhibit inflammation in I/R-induced ALI. We investigated whether propofol could suppress pyroptosis during rI/R-induced ALI by upregulating sirtuin 1 (SIRT1). We generated an in vivo model of rI/R-induced ALI by applying microvascular clamps to the renal pedicles of rats for 45 min. Pathological studies revealed that rI/R provoked substantial lung injury and inflammatory cell infiltration. The rI/R stimulus markedly activated pyroptotic proteins such as NLRP3, ASC, caspase 1, interleukin-1β and interleukin-18 in the lungs, but reduced the mRNA and protein levels of SIRT1. Propofol treatment greatly inhibited rI/R-induced lung injury and pyroptosis, whereas it elevated SIRT1 expression. Treatment with the selective SIRT1 inhibitor nicotinamide reversed the protective effects of propofol during rI/R-induced ALI. Analogous defensive properties of propofol were detected in vitro in rat alveolar macrophages incubated with serum from the rI/R rat model. These findings indicate that propofol attenuates rI/R-induced ALI by suppressing pyroptosis, possibly by upregulating SIRT1 in the lungs.

Abstract
BACKGROUND To investigate the value of plasma high mobility group box protein 1 (HMGB1) in evaluating the prognosis of cerebral ischemia-reperfusion injury (CIRI) in ischemic stroke patients. METHODS 132 ischemic stroke patients were recruited. Before and after thrombolytic therapy at 2 h, 6 h, 12 h, 24 h, and 36 h, the Glasgow Coma Scale (GCS) and National Institutes of Health Stroke Scale (NIHSS) were recorded. The Modified Rankin scale (mRS) was used to assess the prognosis at 3 months. RESULTS The NIHSS score, GCS score and plasma HMGB1 level peaked at 6 h after thrombolytic therapy, and plasma HMGB1 level was positively correlated with infarct volume and NIHSS score, and negatively correlated with GCS score. Plasma HMGB1 level at 6 h had the highest value in identifying patients with poor unfavorable functional outcome after 3 months, with a sensitivity of 86.8% and a specificity of 74.0%. Logistic regression results showed that plasma HMGB1 had a strong association with unfavorable functional outcome [odds ratio (OR) =1.621, P<0.001]. After adjusting for infarct volume and NIHSS score did not attenuate the association (OR=1.381, P=0.005). Finally, we found that plasma HMGB1 at 6 h had the highest value in identifying patients with non-survival after 3 months (χ2=28.655, P<0.001). Logistic regression results showed that plasma HMGB1 had a strong association with non-survival (OR=2.315, P<0.001). After adjusting for infarct volume and NIHSS score did not attenuate the association (OR=2.013, P<0.001). CONCLUSION Plasma HMGB1 exerts a good predictive value for CIRI in ischemic stroke patients, and its increased expression is correlated with worse prognosis.

Abstract
Glutaric aciduria type II (GA2) is an autosomal recessive metabolic disorder of amino acid and lipid metabolism, which is serious and rare. The most serious form is seen in early infancy and is associated with very high mortality rates. Here, we present an 8-month-old male patient with GA2 who had electrocardiographic ST ST-segment depression and sudden cardiac arrest at 10th minute of emergency operation (central venous catheter placement). There is a very scarce amount of data in the literature about anaesthetic management of GA2 patients. There is also no previously published report about cardiac arrest during induction of anaesthesia in this condition. The present report highlights this serious complication.

Abstract
Myocardial ischemia-reperfusion injury (MIRI) is the leading cause of the poor prognosis for patients undergoing clinical cardiac surgery. Micro-RNAs are involved in MIRI; however, the effect of miR-760 on MIRI and the molecular mechanisms behind it have not yet been described. For our in-vivo experiments, 20 rats were randomly distributed between 2 groups (n = 10): the sham-treatment group and the ischemia-reperfusion (I/R) group. For our in-vitro experiments, H9C2 cells were subjected to hypoxia for 6 h, and then reoxygenated to establish an hypoxia-reoxygenation (H/R) model. High expression levels of of miR-760 were observed in the rats subjected to MIRI and the H9C2 cells subjected to H/R. Further, the levels of lactate dehydrogenase (LDH) and malonaldehyde (MDA) were increased, and the size of the myocardial infarct was notably greater in the rats subjected to MIRI, suggesting that miR-760 worsens the effects of MIRI. The inhibitory effects from NaHS on apoptosis were enhanced, as were the expression levels of cleaved caspase 3 and cleaved PARP in H9C2 cells exposed to H/R, and with low-expression levels of miR-760. TargetScan and dual luciferase reporter assays further confirmed the targeted relationship between dual-specificity protein phosphatase (DUSP1) and miR-760. Additionally, miR-760 overexpression and H/R treatment of H9C2 cells inhibited the expression of DUSP1, which further promoted apoptosis. Furthermore, DUSP1 enhanced the anti-apoptotic effects of NaHS in rats subjected to MIRI. Taken together, these findings suggest that miR-760 inhibits the protective effect of NaHS against MIRI.

Abstract
Renal Ischemia/Reperfusion (rI/R)-induced acute lung injury (ALI) is a major problem in rI/R. The objective of the current study was to explore the defensive roles of propofol (Pro), an intravenous anesthetic, on rI/R-induced ALI through mitogen-activated protein kinase (MAPK) signaling. Rats were divided into Sham, Pro (10 mg/kg), rI/R, rI/R + Pro (5 mg/kg), and rI/R + Pro (10 mg/kg) groups. Rats were treated with Pro at 1 h after rI/R treatment. Serum and lung tissues at 24 h after rI/R were collected to evaluate morphological changes and the expression of myeloperoxidase (MPO), inflammatory cytokines, and crucial proteins in the MAPK pathway. Pro attenuated the production of mediators, resulting in reduced levels of autophagy and apoptosis by restricting the MAPK pathway in rI/R-induced ALI model. Pro represses rI/R-induced pulmonary autophagy and apoptosis by decreasing the production of inflammatory molecules, and the effects of Pro are involved in the inhibition of the MAPK pathway.

Abstract
Background The aim of this study was to investigate the potential protective effect of whortleberry by examining the effects on heart tissue at the molecular level of ischemia-reperfusion injury caused by surgical repair of a ruptured abdominal aortic aneurysm. Methods Between May 2018 and February 2019, a total of 32 male Sprague-Dawley rats were randomly assigned into control, sham (ischemia-reperfusion+glycerol), ischemia-reperfusion, and ischemia-reperfusion+whortleberry groups. Hypovolemic shock was applied to the rats in the ischemia-reperfusion groups for one hour. The abdominal aorta was explored following midline laparotomy and atraumatic microvascular clamps were applied from the infrarenal level. Following one-hour ischemia, the clamps were removed, and reperfusion was established for two hours. In the sham group, intraperitoneal glycerol once daily was applied five days before surgery. In the whortleberry group, whortleberry treatment was administered via the intraperitoneal route five days before ischemia-reperfusion. Results The ischemia-reperfusion group exhibited a decrease in the glutathione levels and an increase in the malondialdehyde levels (p<0.01 and p<0.01, respectively). We also observed an increase in the caspase-3 positivity in cardiac myofibrils (p<0.01). Whortleberry administration lowered both malondialdehyde levels and numerical density of caspase-3 positive cardiac myofibrils, while increasing the heart tissue glutathione levels, compared to the ischemia-reperfusion alone group (p<0.01, p=0.011, and p=0.011, respectively). Conclusion Whortleberry may be beneficial in preventing cardiac tissue damage caused by ischemia-reperfusion in the surgical repair of ruptured abdominal aortic aneurysms.
