Abstract
Formononetin has been demonstrated to protect against cerebral ischemia-reperfusion injury, however its mechanism has to be further researched. This study examined the effect of formononetin on cerebral ischemia-reperfusion injury in rats using the PARP-1/PARG/Iduna signaling pathway. In male SD rats, a model of cerebral ischemia-reperfusion injury was developed. Animals were randomly assigned to one of eight groups: Sham operation, Sham operation + formononetin, MCAO, MCAO + formononetin, PARP inhibitor (PJ34) + MCAO, formononetin + PJ34 + MCAO, PARG inhibitor (Ethacridine lactate) + MCAO, and ethacridine lactate + formononetin. The neurological deficit test, TTC staining, HE staining, Nissl staining, TUNEL staining, and western blotting were utilized to assess formononetin's protective effects in MCAO rats. The data show that formononetin can effectively alleviate neurological dysfunction and pathological changes in brain tissue in rats with cerebral ischemia-reperfusion injury, reduce the area of cerebral infarction and neuronal apoptosis, decrease the protein levels of PARP-1, PARG, Caspase-3, P53, and AIF in brain tissue, and increase the protein levels of Iduna and p-AKT. As a result, we concluded that formononetin improves brain ischemia-reperfusion injury in rats by modulating the PARP-1/PARG/Iduna signaling pathway.

Abstract
Cerebral ischemia-reperfusion injury (CIRI) leads to malignant brain edema, blood-brain barrier destruction, and neuronal apoptosis. N6-methyladenosine (m6A) RNA modification in CIRI was still limited explored. In this study, MeRIP- and RNA-sequencing were performed of middle cerebral artery occlusion and reperfusion (MCAO/R) rats to find novel potential molecular targets. Transcription factor TFAP2B stood out of which its m6A abundance decreased associated with a marked reduction of its mRNA based on cojoint interactive bioinformatics analysis of the MeRIP- and RNA-sequencing data. It was suggested TFAP2B could have a role in CIRI. Functionally, overexpression of TFAP2B in cultured primary neurons could effectively improve the cell survival and pro-survival autophagy in parallel with reduced cell apoptosis during OGD/R in vitro. Through the RNA-sequencing of TFAP2B overexpressed primary neurons and subsequent validation experiments, it was found that mitophagy receptor BNIP3 was one of the important targets of TFAP2B in OGD/R neurons through which TFAP2B could bind to its promoter region for transcriptional activation of BNIP3, thereby enhancing BNIP3-mediated mitophagy to protect against OGD/R injury of neurons. Lastly, TFAP2B was demonstrated to alleviate the MCAO/R damage to a certain extent in vivo. Although it failed to confirm TFAP2B dysregulation was m6A dependent in current research, this is the first research of TFAP2B in CIRI field with important guiding significance.

Abstract
Disruption of the blood-brain barrier (BBB) following cerebral ischemia-reperfusion injury (CIRI) is a major factor in the pathophysiology of stroke. Endothelial cell-cell communication is essential for maintaining BBB integrity. By analyzing GSE227651 data, we found that a decrease in endothelial cell-cell communication mediated by Sema3/Nrp1 may be due to the downregulation of Nrp1 transcription, which could contribute to BBB breakdown after CIRI. We confirmed this hypothesis by using western blot analysis to show a reduction in Nrp1 protein levels in penumbra endothelial cells after CIRI in mice. We then overexpressed Nrp1 specifically in brain endothelial cells using adeno-associated virus in mice. Furthermore, Nrp1 overexpression had a protective effect on BBB integrity, as evidenced by a decrease in IgG and albumin leakage caused by CIRI in mice. Finally, we found that Nrp1 overexpression also reduced brain cell death and neurological deficits induced by cerebral ischemia-reperfusion in mice. Our findings suggest that Nrp1 downregulation may be a key factor in the breakdown of endothelial cell-cell communication and subsequent BBB disruption following CIRI. Targeting Nrp1-mediated pathways may be a promising approach for mitigating BBB damage and alleviating neurological consequences in stroke patients.

Abstract
BACKGROUND AND PURPOSE Cerebral ischemia‒reperfusion injury causes significant harm to human health and is a major contributor to stroke-related deaths worldwide. Current treatments are limited, and new, more effective prevention and treatment strategies that target multiple cell components are urgently needed. Leucine-rich alpha-2 glycoprotein 1 (Lrg1) appears to be associated with the progression of cerebral ischemia‒reperfusion injury, but the exact mechanism of it is unknown. METHODS Wild-type (WT) and Lrg1 knockout (Lrg1-/-) mice were used to investigate the role of Lrg1 after cerebral ischemia‒reperfusion injury. The effects of Lrg1 knockout on brain infarct volume, blood‒brain barrier permeability, and neurological score (based on 2,3,5-triphenyl tetrazolium chloride, evans blue dye, hematoxylin, and eosin staining) were assessed. Single-cell RNA sequencing (scRNA-seq), immunofluorescence, and microvascular albumin leakage tests were utilized to investigate alterations in various cell components in brain tissue after Lrg1 knockout. RESULTS Lrg1 expression was increased in various cell types of brain tissue after cerebral ischemia‒reperfusion injury. Lrg1 knockout reduced cerebral edema and infarct size and improved neurological function after cerebral ischemia‒reperfusion injury. Single-cell RNA sequencing analysis of WT and Lrg1-/- mouse brain tissues after cerebral ischemia‒reperfusion injury revealed that Lrg1 knockout enhances blood‒brain barrier (BBB) by upregulating claudin 11, integrin β5, protocadherin 9, and annexin A2. Lrg1 knockout also promoted an anti-inflammatory and tissue-repairing phenotype in microglia and macrophages while reducing neuron and oligodendrocyte cell death. CONCLUSIONS Our results has shown that Lrg1 mediates numerous pathological processes involved in cerebral ischemia‒reperfusion injury by altering the functional states of various cell types, thereby rendering it a promising therapeutic target for cerebral ischemia‒reperfusion injury.

Abstract
Neuroinflammation and oxidative stress damage are involved in the pathogenesis of cerebral ischemia-reperfusion injury (CIRI). Ferroptosis emerged as a new player in the regulation of lipid peroxidation processes. This study aimed at exploring the potential involvement of ciprofol on ferroptosis-associated CIRI and subsequent neurological deficits in the mouse model of transient cerebral ischemia and reperfusion. Cerebral ischemia was built in male C57BL/6 J wild-type (WT) and Nrf2-knockout (Nrf2 KO) mice in the manner of middle cerebral artery occlusion (MCAO) followed by reperfusion. Ciprofol improved autonomic behavior, alleviated reactive oxygen species output and ferroptosis-induced neuronal death by nucleus transportation of NFE2 like BZIP transcription factor 2 (Nrf2) and the promotion of heme oxygenase 1 (Ho-1), solute carrier family 7 member 11 (SLC7A11/xCT), and glutathione peroxidase 4 (GPX4). Additionally, ciprofol improved neurological scores and reduced infarct volume, brain water content, and necrotic neurons. Cerebral blood flow in MCAO-treated mice was also improved. Furthermore, absence of Nrf2 abrogated the neuroprotective actions of ciprofol on antioxidant capacity and sensitized neurons to oxidative stress damage. In vitro, the primary-cultured cortical neurons from mice were pre-treated with oxygen-glucose deprivation/reperfusion (OGD/R), followed by ciprofol administration. Ciprofol effectively reversed OGD/R-induced ferroptosis and accelerated transcription of GPX4 and xCT. In conclusion, we investigated the ciprofol-induced inhibition effect of ferroptosis-sheltered neurons from lipid preoxidation in the pathogenesis of CIRI via Nrf2-xCT-GPX4 signaling pathway.

Abstract
Alterations in the M1/M2 polarization phenotype significantly affect disease progression. Antioxidant and anti-inflammatory protective effects of resveratrol (Res) have been demonstrated. This paper tested the hypothesis that Res could protect against cerebral ischemia-reperfusion injury (CI/RI) by modulating microglial polarization via the miR-450b-5p/KEAP1/Nrf2 pathway. Rats were first treated with Res and adenovirus that interfered with miR-450b-5p or KEAP1, and then established a middle cerebral artery occlusion-reperfusion model using modified nylon sutures. Rats were then evaluated for neurological and behavioral functions, and markers of M2 microglia were detected by immunofluorescence staining. Additionally, the signature patterns of miR-450b-5p, KEAP1, and Nrf2 were determined. The collected data demonstrated that Res exerted neuroprotective effects in CI/RI by promoting microglial M2 polarization. Additionally, Res could regulate the Nrf2 pathway by targeting KEAP1 by up-regulating miR-450b-5p. Up-regulating miR-450b-5p or down-regulating KEAP1 could further promote the protective effect of Res, while down-regulating miR-450b-5p or up-regulating KEAP1 worked oppositely. Our study demonstrates that Res exerts neuroprotective effects on microglial M2 polarization through the miR-450b-5p/KEAP1/Nrf2 pathway during CI/RI.

Abstract
Cerebral ischemic stroke (CIS) has become the second leading cause of death worldwide, which is largely related to cerebral ischemia reperfusion injury (CIRI). Surgical intervention is a reliable treatment for CIS, which predictably causes cerebral reperfusion. Therefore, the choice of anesthetic drugs has important clinical significance. Isoflurane (ISO), one of the most used anesthetics, attenuates cognitive impairment and has brain protective effects. However, the role of isoflurane in regulating autophagy and its regulatory mechanism on inflammation in CIRI are still unclear. The middle cerebral artery occlusion (MCAO) method was used to establish a rat model of CIRI. After 24 h of reperfusion, all rats were evaluated by mNSS scoring and dark avoidance experiment. Western blotting and immunofluorescence were used to examine the expression of key proteins. Compared with the sham group, the MCAO group showed increased neurobehavioral scores and decreased cognitive memory function (P < 0.05). As for the ISO-treated MCAO rats, the neurobehavioral score was significantly decreased, the expression of AMPK, ULK1, Beclin1, and LC3B was significantly increased, and the cognitive and memory functions were also significantly improved (P < 0.05). After inhibition of autophagy pathway or key protein AMPK in autophagy, neurobehavioral scores and protein expression of NLRP3, IL-1β, and IL-18 were significantly increased (P < 0.05). Isoflurane post-treatment may enhance autophagy by activating the AMPK/ULK1 signaling pathway and further inhibit the release of inflammatory factors from NLRP3 inflammasomes, thereby ameliorating neurological function and cognitive impairment and exerting a protective effect on the brain in CIRI rats.

Abstract
Buyang Huanwu decoction, a classic traditional Chinese prescription, has been used to prevent and treat stroke for hundreds of years. An increasing number of the laboratory research on Buyang Huanwu decoction used in treating cerebral ischemia-reperfusion injury have been published recently. However, the problem of methodological and reporting quality of some studies is lack of assessment. This study aims to evaluate the methodological and reporting quality of the research on Buyang Huanwu decoction against experimental cerebral ischemia-reperfusion injury. A comprehensive search on six databases was performed. Two researchers independently screened the literature considering the eligibility criteria. Methodological and reporting quality of the included studies were evaluated by the Systematic Review Centre for Laboratory Animal Experimentation (SYRCLE) risk-of-bias tool and Animal Research: Reporting of In Vivo Experiments (ARRIVE) guideline. Forty-five studies met the inclusion criteria. No study achieved a decent overall rating in using the SYRCLE tool (percentage of items with "low risk" ≥ 50%). Of the 22 items on the SYRCLE tool, only 7 items (31.82%) were rated as "low risk" in more than 50% of the included studies. Of the 39 items of ARRIVE guideline, 14 (35.9%) items were rated as "yes" in more than 50% of the included studies. The methodological and reporting quality of Buyang Huanwu decoction for experimental cerebral ischemia-reperfusion injury was substandard, which needed to be further improved. The limitations should be addressed when planning similar studies in the future. Additionally, these findings provided evidence-based guidance for future preclinical studies evaluating the efficacy of Buyang Huanwu decoction in the treatment of cerebral ischemia-reperfusion injury.

Abstract
Cerebral ischemia, one of the leading causes of neurological dysfunction of brain cells, muscle dysfunction, and death, brings great harm and challenges to individual health, families, and society. Blood flow disruption causes decreased glucose and oxygen, insufficient to maintain normal brain tissue metabolism, resulting in intracellular calcium overload, oxidative stress, neurotoxicity of excitatory amino acids, and inflammation, ultimately leading to neuronal cell necrosis, apoptosis, or neurological abnormalities. This paper summarizes the specific mechanism of cell injury that apoptosis triggered by reperfusion after cerebral ischemia, the related proteins involved in apoptosis, and the experimental progress of herbal medicine treatment through searching, analyzing, and summarizing the PubMed and Web Of Science databases, which includes active ingredients of herbal medicine, prescriptions, Chinese patent medicines, and herbal extracts, providing a new target or new strategy for drug treatment, and providing a reference for future experimental directions and using them to develop suitable small molecule drugs for clinical application. With the research of anti-apoptosis as the core, it is important to find highly effective, low toxicity, safe and cheap compounds from natural plants and animals with abundant resources to prevent and treat Cerebral ischemia/reperfusion (I/R) injury (CIR) and solve human suffering. In addition, understanding and summarizing the apoptotic mechanism of cerebral ischemia-reperfusion injury, the microscopic mechanism of CIR treatment, and the cellular pathways involved will help to develop new drugs.

Abstract
Ischemic damage to the central nervous system (CNS) is a catastrophic postoperative complication of aortic occlusion subsequent to cardiovascular surgery that can cause brain impairment and sometimes even paraplegia. Over recent years, numerous studies have investigated techniques for protecting and revascularizing the nervous system during intraoperative ischemia; however, owing to a lack of knowledge of the physiological distinctions between the brain and spinal cord, as well as the limited availability of testing techniques and treatments for ischemia-reperfusion injury, the cause of brain and spinal cord ischemia-reperfusion injury remains poorly understood, and no adequate response steps are currently available in the clinic. Given the limited ability of the CNS to repair itself, it is of great clinical value to make full use of the proliferative and differentiation potential of stem cells to repair nerves in degenerated and necrotic regions by stem cell transplantation or mobilization, thereby introducing a novel concept for the treatment of severe CNS ischemia-reperfusion injury. This review summarizes the most recent advances in stem cell therapy for ischemia-reperfusion injury in the brain and spinal cord, aiming to advance basic research and the clinical use of stem cell therapy as a promising treatment for this condition.

Abstract
Cerebral ischemia-reperfusion injury (CIRI) may lead to severe disability even death, but the strategies for prevention and treatment are still limited. Transcutaneous electrical acupoint stimulation (TEAS) has been reported to have a significant neuroprotection against CIRI, but the underlying mechanisms remain obscure. In this study, we established a focal cerebral ischemia-reperfusion model in male Sprague-Dawley rats. TEAS pretreatment was applied to Baihui (GV20), Sanyinjiao (SP6) and Zusanli (ST36) acupoints for 5 consecutive days before CIRI. After 24 h reperfusion, the brain damage was assessed using Zea-Longa score, brain water content (BWC) and infarct volume. Meanwhile, the number of activated microglia and the TNF-α were detected by immunofluorescence and ELISA respectively. Moreover, Western Blot and RT-qPCR were conducted to detect the proteins and mRNA expressions of Nrf2, HO-1, iNOS and Arg-1. We found that TEAS pretreatment significantly reduced Longa score, BWC, infarct volume and the number of activated microglia. Besides, TEAS pretreatment increased Nrf2 and HO-1 levels, while lowered the expression of TNF-α. Subsequently, we also discovered that the microglia M1 phenotype maker iNOS decreased and the M2 maker Arg-1 increased after TEAS pretreatment. However, these effects of TEAS pretreatment were markedly eliminated by brusatol. These findings clearly suggested that TEAS pretreatment exerted neuroprotection against CIRI, which might be related to modulating microglia polarization and neuroinflammation via Nrf2/HO-1 pathway.

Abstract
Circular RNAs (circRNAs) are abundantly expressed in human central nervous system. Here, we explored the role of circ_Arhgap5 in cerebral ischemia/reperfusion (I/R)-induced nerve injury in PC12 cells and its associated mechanism. Cell proliferation ability was assessed by 5-Ethynyl-2'-deoxyuridine (Edu) assay and 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Flow cytometry (FCM) was applied to assess cell apoptotic rate. Cell death was analyzed by lactate dehydrogenase (LDH) assay. Oxygen-glucose deprivation and reoxygenation (OGD/R) up-regulates the expression of circRNA Rho GTPase activating protein 5 (circ_Arhgap5; mmu_circ_0000377) in PC12 cells. OGD/R exposure inhibited the proliferation and induced the apoptosis of PC12 cells, and the silence of circ_Arhgap5 attenuated OGD/R-induced injury in PC12 cells. miR-29a-3p was identified as a target of circ_Arhgap5 in PC12 cells. Circ_Arhgap5 knockdown-mediated protective effects in OGD/R-induced PC12 cells were reversed by the interference of miR-29a-3p. miR-29a-3p interacted with the 3' untranslated region (3'UTR) of Rho-associated coiled-coil-containing protein kinase 1 (Rock1), and circ_Arhgap5 can positively regulate Rock1 expression by sponging miR-29a-3p in PC12 cells. miR-29a-3p overexpression protected PC12 cells against OGD/R-induced damage by down-regulating Rock1. In conclusion, circ_Arhgap5 silencing protected PC12 cells from OGD/R-induced injury through mediating miR-29a-3p/Rock1 axis.

Abstract
Antioxidants represent a potential therapy for cerebral ischemia-reperfusion injury (CIRI). Compounds which exhibit both direct and indirect antioxidative activity may potentially exert improved effects. Hence, we aimed to assess whether the dual antioxidant DH-217, a derivative of DHAP clinically used to treat coronary heart disease, can reduce oxidative stress damage and elucidate the underlying mechanism. Hydrogen peroxide (H2O2)-induced and Middle Cerebral Artery Occlusion (MCAO)-induced damages were used to imitate oxidative stress. The antioxidation of DH-217 was determined by MTT, ROS, colony and DPPH assay. Besides, immunofluorescence, Real-Time PCR Analyses, western blotting and si-RNA/Plasmid-induced protein expression were used for mechanism validation. DPPH scavenging assay evidenced DH-217 was a well free radical scavenger. Cell survival assay also showed that DH-217 had a significant cytoprotection through direct and indirect clearance mechanisms. Further, it clearly inhibited oxidative stress-induced IkappaB kinase beta (IKKβ) phosphorylation and increased heme oxygenase-1 (HO-1) expression. Significantly, these antioxidant beneficial effects were reversed by HO-1 inhibitor, si-nuclear erythroid 2-related factor 2 (Nrf2) and IKKβ plasmid. Meanwhile, DH-217 had a good neuroprotective effect on CIRI rats. The dual antioxidant DH-217 has potential reference value for drug development of CIRI. Furthermore, inhibition of IKKβ phosphorylation and activation of Nrf2/HO-1 could be a promising antioxidant pathway. Dual antioxidant DH-217 not only has the ability of directly scavenging ROS, but also can clear it by targeting IKKβ/Nrf2/HO-1 signal axis. Inhibition of IKKβ phosphorylation and activation of Nrf2/HO-1 may be a promising antioxidant pathway for CIRI.

Abstract
Cerebral ischemia-reperfusion injury (CI/RI) injury is a common feature of ischemic stroke which occurs when the blood supply is restored after a period of ischemia in the brain. Reduced blood-flow to the brain during CI/RI compromises neuronal cell health as a result of mitochondrial dysfunction, oxidative stress, cytokine production, inflammation and tissue damage. Reperfusion therapy during CI/RI can restore the blood flow to ischemic regions of brain which are not yet infarcted. The long-term goal of CI/RI therapy is to reduce stroke-related neuronal cell death, disability and mortality. A range of drug and interventional therapies have emerged that can alleviate CI/RI mediated oxidative stress, inflammation and apoptosis in the brain. Herein, we review recent studies on CI/RI interventions for which a mechanism of action has been described and the potential of these therapeutic modalities for future use in the clinic.

Abstract
Acute ischemic stroke (AIS) is a serious threat to human health. Following AIS, cerebral ischemia-reperfusion injury (CIRI) must be treated to improve prognosis. By combining 4D label-free quantitative proteomics with lactylation modification-specific proteomics analysis, we assessed lysine lactylation (Kla) in cortical proteins of a CIRI rat model. We identified a total of 1003 lactylation sites on 469 proteins in this study, gathering quantitative information (PXD034232) on 660 of 310 proteins, which were further classified by cell composition, molecular function, and biological processes. In addition, we analyzed the metabolic pathways, domains, and protein-protein interaction networks. Lastly, we evaluated differentially expressed lysine lactylation sites, determining 49 upregulated proteins and 99 downregulated proteins with 54 upregulated sites and 54 downregulated sites in the experimental group in comparison with the healthy control group. Moreover, we identified the Kla of Scl25a4 and Slc25a5 in the Ca2+ signaling pathway, but the Kla of Vdac1 was eliminated, as confirmed in vivo. Overall, these results provide new insights into lactylation involved in the underlying mechanism of CIRI because this post-translational modification affects the mitochondrial apoptosis pathway and mediates neuronal death. Therefore, this study may enable us to develop new molecules with therapeutic properties, which have both theoretical significance and broad clinical application prospects. A new model of cerebral ischemia-reperfusion injury (CIRI) induced by lactylation through the regulation of key proteins of the Ca2+ signaling pathway.

Abstract
Cerebral ischemia–reperfusion (I/R) injury is the leading cause of death in severe hypotension caused by cardiac arrest, drowning, and excessive blood loss. Urine can sensitively reflect pathophysiological changes in the brain even at an early stage. In this study, a rat model of global cerebral I/R injury was established via Pulsinelli’s four-vessel occlusion (4-VO) method. Overall, 164 urinary proteins significantly changed in the 4-VO rat urine samples compared to the control samples by data-independent acquisition (DIA) proteomics technique (1.5-fold change, p < 0.05). Gene Ontology annotation showed that the acute-phase response, the ERK1 and ERK2 cascade, endopeptidase activity, blood coagulation, and angiogenesis were overrepresented. After parallel reaction monitoring (PRM) validation, 15 differential proteins having human orthologs were verified as the potential urinary markers associated with cerebral I/R injury. Of these potential biomarkers, 8 proteins were reported to be closely associated with cerebral I/R injury. Nine differential proteins changed even when there were no clinical manifestations or histopathological cerebral damage, including FGG, COMP, TFF2, HG2A, KNG1, CATZ, PTGDS, PRVA, and HEPC. These 9 proteins are potential biomarkers for early screening of cerebral I/R injury to prevent the development of cerebral injury. KNG1, CATZ, PTGDS, PRVA, and HEPC showed an overall trend of upregulation or downregulation at 12 and 48 h after I/R injury, reflecting the progression of cerebral I/R injury. These 5 proteins may serve as potential biomarkers for prognostic evaluation of cerebral I/R injury. These findings provide important clues to inform the monitoring of cerebral I/R injury and further the current understanding of its molecular biological mechanisms.

Abstract
Inflammatory reaction and neuronal apoptosis are the major pathophysiological mechanisms involved in cerebral ischemia-reperfusion injury (CI/RI). It has been reported that Zhongfeng Capsules (ZFCs), which contain Panax notoginseng, Hirudo, Red ginseng, Eupolyphaga sinensis, Pangolin scales, Rhubarb, and Radix Salvia miltiorrhizae, have a definite therapeutic effect on CI/RI. However, the specific molecular mechanisms of ZFCs are unclear. In this study, the effects of ZFCs on middle cerebral artery occlusion were investigated in rats. Our results showed that neurological impairment and neuronal apoptosis were alleviated in ZFC-treated rats. Additionally, infarct volume and cerebral edema decreased and there was an improvement in histopathological features. Furthermore, the expression levels of IL-1β, IL-6, and TNF-α were downregulated in ZFC-treated rats. TLR 4, NF-κB, Bax, and Caspase-3 expression also tended to decrease, whereas the expression of Bcl-2, p-PI3K, p-Akt, and I-κBα increased. The results indicate that the ZFCs effectively protected the rats against CI/RI possibly via the TLR4/NF-κB signaling pathway. Additionally, the formulation regulated the transcriptional activity of NF-κB, secretion of downstream inflammatory factors, and the expression of Bcl-2-Bax proteins in the PI3K/Akt pathway. Our findings suggest that ZFCs suppress neuronal apoptosis and inflammatory reaction via the PI3K/Akt and TLR4/NF-κB signaling pathways, respectively. Moreover, activation of the PI3K/Akt pathway may result in the inhibition of proinflammatory cytokine secretion, which may be another mechanism by which ZFCs alleviate CI/RI.

Abstract
LncRNA five prime to Xist (FTX) has been identified to exert a protective effect in multiple diseases. However, whether and how FTX attenuates cerebral ischemia-reperfusion injury (CI/RI) is still unclear. To simulate CI/RI, an in vitro oxygen-glucose deprivation/reoxygenation (OGD/R) HT22 cell model and an in vivo middle cerebral artery occlusion/reperfusion (MCAO/R) Sprague-Dawley rat model were respectively constructed. In CI/RI plasma samples, OGD/R-challenged HT22 cells, and brain tissues from MCAO/R rats, FTX and mouse double minute 4 (MDM4) expressions were substantially decreased while miR-186-5p abundance was evidently increased. It was also revealed that FTX obviously improved neuronal damage induced by OGD/R through increasing proliferation, reducing apoptosis, and alleviating oxidative stress in OGD/R-challenged HT22 cells. Additionally, FTX positively regulated MDM4 level in OGD/R-treated HT22 cells as a sponge of miR-186-5p. Moreover, miR-186-5p upregulation or MDM4 suppression restored the inhibitory effects of FTX upregulation on OGD/R-triggered neuronal damage in HT22 cells. Therefore, these results suggest that FTX might ameliorate CI/RI by regulating the miR-186-5p/MDM4 pathway, providing a new target for stroke impairment treatment.

Abstract
Cerebral ischemia is a major health threat to humankind around the world, and the reperfusion methods may provoke irreversible damages to brain tissues, causing impairment of neurological function. The goal of this study is to investigate the potential neurological protective effect of PJ34, a well-characterized poly (ADP-ribose) polymerase 1 (PARP-1) inhibitor, on cerebral ischemia-reperfusion (I/R)-induced injury of the rat model. The cerebral I/R rats were received (3, 6, or 12 mg/kg) injections of PJ34 or saline at 24 h, 6 h before middle cerebral artery occlusion (MCAO) and 1 h, 24 h, and 48 h after MCAO. All rats were subject to the neurological behavior tests by open field test and Morris water maze test. The expression of pro-inflammatory cytokines, Cyclooxygenase 2 (COX-2) and inducible nitric oxide synthase (iNOS) in cerebral tissues was also determined. Our results demonstrated that the administration of PJ34 dose-dependently ameliorated cerebral I/R-induced injury and improved neurological performance of cerebral I/R rats. We also revealed that PJ34 treatment effectively reduced COX2, iNOS, and pro-inflammatory cytokine levels in the I/R-induced injury tissues. Our finding further supports that inhibition of PARP-1 activity is beneficial for reducing post-I/R-induced brain damage via targeting inflammatory response.

Abstract
Piceatannol is a natural plant-derived compound with protective effects against cardiovascular diseases. However, its effect on cerebral ischaemia-reperfusion injury (CIRI) induced by oxidative stress remains unclear. This study aimed to investigate piceatannol's antioxidation in CIRI. An in vitro oxygen-glucose deprivation followed by reoxygenation model was used and cell viability was measured. A middle cerebral artery occlusion followed by reperfusion model was used in vivo. Neurological function, encephalisation quotient, oedema, and volume of the cerebral infarction were then evaluated. The effects of piceatannol on histopathological findings, as well as the ultrastructure of the cortex, were analysed. The activity of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and lactate dehydrogenase (LDH) and the malondialdehyde (MDA) content was measured both in vitro and in vivo. Finally, the expression of nuclear factor erythroid-2-related factor 2 (Nrf2), hemeoxygenase-1 (HO-1), and nicotinamide adenine dinucleotide phosphate quinone oxidoreductase 1 (NQO1) in cerebral tissue was detected using reverse transcription quantitative polymerase chain reaction (RT-qPCR) and western blotting. Our results demonstrated that cell viability in the piceatannol groups was increased. The SOD, GSH-Px activities were increased as LDH activity and MDA content decreased in the piceatannol groups both in vitro and in vivo, reflecting a decrease in oxidative stress. The neurological severity score and infarction volume in the piceatannol groups at doses of 10 and 20 mg/kg were lower than those of the model group. Furthermore, the damage seen on histopathological examination was partially attenuated by piceatannol. RT-qPCR and western blot analysis indicated that the expression of Nrf2, HO-1, and NQO1 were significantly increased by piceatannol. The results of the study demonstrate that piceatannol exerts a protective effect against CIRI.

Abstract
Ischemia-reperfusion frequently occurs in ischemic cerebral vascular disease, during which the inflammatory signaling plays essential roles. The aim of this study was to discover the efficacy of the antibody to a key immune cytokine IL-23 (anti-IL-23) for the therapy of cerebral ischemia-reperfusion injury. We established the cerebral ischemia-reperfusion injury model by middle cerebral artery occlusion (MCAO). Anti-IL-23 injection attenuated lesions indicated by histology study. RT-PCR and Western blot were employed to detect the mRNA and protein expression of JAK2 and STAT3 after anti-IL-23 treatment. ELISA was utilized to measure the levels of MDA (malondialdehyde) and superoxide dismutase (SOD). Moreover, curcumin and IL-6 were implicated in the endogenous intervention of IL-23 signaling in vivo. Our data demonstrated that the treatment of anti-IL-23 might transcriptionally activate the classic immune pathway in the brain. Anti-IL-23 augmented phosphorylation levels of both JAK2 and STAT3, suggesting the amplification signaling of JAK/STAT after exogenous IL-23 intervention. Anti-IL-23 reduced ROS molecules of STAT downstream in the serum and brain. It also alleviated the injury by bringing down levels of MDA and SOD in the serum. JAK2 inhibitor could abolish the effect of anti-IL-23 whereas JAK3 ameliorated the injury. The combination of anti-IL-23 and JAK3i could reduce infarct volume more effectively. In summary, this study indicated that anti-IL-23 had protective effects against cerebral ischemia-reperfusion injury by targeting the immune specific JAK2-STAT3 in JAK/STAT pathway.

Abstract
BACKGROUND Long non-coding RNA (lncRNA) small nucleolar RNA host gene 14 (SNHG14) is associated with cerebral ischemia-reperfusion (CI/R) injury. This work aims to explore the role of SNHG14 in CI/R injury. METHODS HT22 (mouse hippocampal neuronal cells) cell model was established by oxygen-glucose deprivation/reoxygenation (OGD/R) treatment. The interaction among SNHG14, miR-182-5p and BNIP3 was verified by luciferase reporter assay. Flow cytometry, western blot and quantitative real-time PCR were performed to examine apoptosis, the expression of genes and proteins. RESULTS SNHG14 and BNIP3 were highly expressed, and miR-182-5p was down-regulated in the OGD/R-induced HT22 cells. OGD/R-induced HT22 cells exhibited an increase in apoptosis. SNHG14 overexpression promoted apoptosis and the expression of cleaved-caspase-3 and cleaved-caspase-9 in the OGD/R-induced HT22 cells. Moreover, SNHG14 up-regulation enhanced the expression of BNIP3, Beclin-1, and LC3II/LC3I in the OGD/R-induced HT22 cells. Furthermore, SNHG14 regulated BNIP3 expression by sponging miR-182-5p. MiR-182-5p overexpression or BNIP3 knockdown repressed apoptosis in OGD/R-induced HT22 cells, which was abolished by SNHG14 up-regulation. CONCLUSION Our study demonstrates that lncRNA SNHG14 promotes OGD/R-induced neuron injury by inducing excessive mitophagy via miR-182-5p/BINP3 axis in HT22 mouse hippocampal neuronal cells. Thus, SNHG14/miR-182-5p/BINP3 axis may be a valuable target for CI/R injury therapies.

Abstract
OBJECTIVE MicroRNAs (miRNAs) have been reported in cerebral ischemia-reperfusion injury, yet the function of miR-27a in it has seldom been mentioned. This study aims to assess the mechanisms of miR-27a in rats with cerebral ischemia-reperfusion injury. METHODS The cerebral ischemia-reperfusion models of rat pups were established by bilateral carotid artery occlusion. Rats were treated with miR-27a agomir, silenced HSP90 expression plasmids or PI3K/AKT/mTOR pathway agonist. Oxidative stress indices, inflammatory factors, brain tissue water content, cerebral infarct volume, neurological function score and neuronal apoptosis in rats with cerebral ischemia-reperfusion injury were measured. MiR-27a and HSP90 expression and PI3K/AKT/mTOR phosphorylation levels in the brain tissues of rats were also detected. RESULTS MiR-27a expression and PI3K/AKT/mTOR phosphorylation levels were downregulated while HSP90 expression was upregulated in cerebral ischemia-reperfusion injury rats. Elevated miR-27a or reduced HSP90 diminished water content, neuronal apoptosis and infarct volume, suppressed oxidative stress and inflammatory response, as well as improved neurological deficits and pathological damages. Moreover, elevated miR-27a or silenced HSP90 upregulated PI3K/AKT/mTOR phosphorylation levels in cerebral ischemia-reperfusion injury rats. HSP90 silencing or PI3K/AKT/mTOR pathway agonist reversed the unfavorable effects of low miR-27a expression on cerebral ischemia-reperfusion injury rats. CONCLUSION To conclude, our study demonstrates that elevated miR-27a or decreased HSP90 attenuates oxidative stress and inflammatory response, and improves neurological function in cerebral ischemia-reperfusion injury rats by activating PI3K/AKT/mTOR signaling pathway.

Abstract
The study was to investigate the effects of ligustrazine on rats with cerebral ischemia-reperfusion (I/R) injury and to explore the potential mechanism. Transient focal cerebral ischemia Wistar rat model was established through middle cerebral artery occlusion. The cerebral I/R injury rats were treated with intraperitoneal injection of ligustrazine (1, 3, and 10 mg/kg). Human amniotic epithelial cells (HAECs) were treated with ligustrazine (1, 10, 100 μM) and PI3K inhibitor wortmannin (100 μM), following oxygen-glucose deprivation (OGD) treatment. The expression levels of protein kinase B (PKB or AKT), phospho-Akt (p-Akt), endothelial nitric oxide synthase (eNOS), and phosphor-eNOS (p-eNOS) in HAECs and brains of rats were measured by Western blot. The levels of nitric oxide (NO) in HAECs were measured by Griess method using NO2-/NO3- Assay Kit. Infarct volume and neurological deficits were evaluated 24 h after reperfusion. The levels of NO, p-Akt/Akt, and p-eNOS/eNOS in HAECs were significantly reduced after OGD, but ligustrazine treatment increased the levels of those factors in a dose-dependent manner, while those increases were reversed by PI3K inhibitor wortmannin. Similarly, p-Akt/Akt and p-eNOS/eNOS in brain tissue of rats with I/R were significantly reduced compared with control group (p < 0.05), but ligustrazine treatment increased the levels of p-Akt and p-eNOS in a dose-dependent manner (p < 0.05), while those increases were also reversed by using wortmannin. Ligustrazine also improved the damage of rat brain tissue caused by I/R, but wortmannin reversed the improvement. Ligustrazine plays a neuroprotective role in rats with cerebral I/R injury through the activation of PI3K/Akt pathway.

Abstract
This study aimed to investigate whether ischemic postconditioning (IpostC) alleviates cerebral ischemia/reperfusion (I/R) injury involved in autophagy. Adult Sprague–Dawley rats were divided into five groups: sham (sham surgery), I/R (middle cerebral artery occlusion [MCAO] for 100 min, then reperfusion), IpostC (MCAO for 100 min, reperfusion for 10 min, MCAO for 10 min, then reperfusion), IpostC+3MA (3-methyladenine, an autophagy inhibitor, administered 30 min before first reperfusion), and IpostC+Veh (vehicle control for IpostC+3MA group). Infarct volume was measured using cresyl violet staining. Autophagy-related proteins were detected by western blot and immunohistochemistry. Autophagosomes, autophagolysosomes, and mitochondrial damage were identified by transmission electron microscopy. Cortical cell apoptosis was detected by the TUNEL assay. Neurologic function was assessed using the modified Neurologic Severity Score. IpostC improved neurological function and reduced infarct volume after I/R (P < 0.05). These effects of IpostC were inhibited by 3MA (P < 0.05). Autophagosome formation was increased in the I/R and IpostC+Veh groups (P < 0.05), but not in the IpostC+3MA group. The I/R group showed enhanced LC3-II/LC3-I ratio, p62, and Cathepsin B levels and decreased LAMP-2 level (all P < 0.05 vs. sham), indicating dysfunction of autophagic clearance. IpostC reduced p62 and Cathepsin B levels and increased the LC3-II/LC3-I ratio, and nuclear translocation of transcription factor EB (all P < 0.05); these effects of IpostC were reversed by 3MA, suggesting IpostC enhanced autophagic flux. Furthermore, IpostC attenuated I/R-induced mitochondrial translocation of Bax and mitochondrial cytochrome-c release (all P < 0.05); 3MA inhibited these effects of IpostC (P < 0.05). In conclusion, IpostC may alleviate cerebral I/R injury by activating autophagy during early reperfusion.

Abstract
Cerebral ischemia-reperfusion (I/R) injury usually contributes to mortality and disability after ischemic stroke. Ginkgolides injection (GIn), a standard preparation composed of ginkgo diterpene lactones extract, is clinically used for neuroprotective treatment on reconvalescents of cerebral infarction. However, the understanding about its therapeutic mechanism is still lacking. In this study, a gas chromatography-mass spectrometry (GC-MS) based metabolomic approach coupled with multivariate data analysis (MVDA) was applied to explore the neuroprotective effects of GIn in a rodent model of focal ischemic stroke induced by transient middle cerebral artery occlusion (tMCAO). Metabolomic profiling revealed a series of metabolic perturbations that underlie the cerebral I/R pathological events. GIn can reverse the I/R induced brain metabolic deviations by modulating multiple metabolic pathways, such as glycolysis, Krebs cycle, pentose phosphate pathway (PPP), γ-aminobutyrate (GABA) shunt and lipid metabolism. Moreover, the main bioactive components of GIn were distributed to brain tissue much more easily in tMCAO rats than in normal rats after an intravenous administration, suggesting that the increased cerebral exposure to ginkgolides in I/R pathological condition potentially facilitated the neuroprotective effects of GIn by directly targeting at brain. The present study provided valuable information for our understanding about metabolic changes of cerebral I/R injury and clinical application of GIn.

Abstract
Stroke is a leading cause of long-term disability and death in the United States. Currently, tissue plasminogen activator (tPA), is the only Food and Drug Administration-approved treatment for acute ischemic stroke. However, the use of tPA is restricted to a small subset of acute stroke patients due to its limited 3-h therapeutic time window. Given the limited therapeutic options at present and the multi-factorial progression of ischemic stroke, emphasis has been placed on the discovery and use of combination therapies aimed at various molecular targets contributing to ischemic cell death. Protein kinase C (PKC) and Akt (protein kinase B) are serine/threonine kinases that play a critical role in mediating ischemic-reperfusion injury and cellular growth and survival, respectively. The present review will examine the role of PKC and Akt in the cellular response to ischemic-reperfusion injury.

Abstract
Previous studies have shown that levo-dopamine (L-dopa) can improve the consciousness of certain patients with prolonged coma after cerebral ischemia-reperfusion injury, and promote cell growth in vivo. This study aimed to investigate whether L-dopa, which is used clinically to treat Parkinson's disease, might also ameliorate ischemia-reperfusion injury-induced cell death. The oxygen-glucose deprivation and re-oxygenation (OGD/R) model was used to mimic the ischemia-reperfusion pathological process in vitro. HT22 cells were treated with dopamine hydrochloride at different times (i.e., 2 h prior to OGD, during the period of OGD, during the period of R, and throughout the period of OGD/R) and at different concentrations (i.e., 25 μM, 50 μM, 100 μM). Lactate dehydrogenase (LDH) release, flow cytometry-annexin V, and propidium iodide staining with light microscopy showed that dopamine hydrochloride (added during re-oxygenation) promoted cell proliferation and facilitated maintenance of normal cell morphology. However, when present during oxygen-glucose deprivation for 18 h and present throughout OGD/R, dopamine hydrochloride increased cell damage as manifested by shrinkage, rounding up, and reduced viability. In conclusion, dopamine protected HT22 cells from OGD/R injury-induced cell death only at a particular point in time, suggesting that it may be useful for treating severe ischemia-reperfusion brain injury.

Abstract
AIM Cerebral ischemia-reperfusion (I/R) injury is a devastating complication in the perioperative period. Transforming growth factor beta (TGF-β) is a key protein that can participate in the repair and control process responses after I/R injury. Isoflurane is widely used in neurosurgery. Previous studies have shown that isoflurane preconditioning plays an important role in neuroprotection. However, the effects of isoflurane postconditioning on cerebral I/R injury have not yet been elucidated. In the present study, we evaluated the protective effect of isoflurane postconditioning against cerebral I/R injury and investigated the role of the TGF-β signaling pathway and the downstream c-Jun N-terminal kinase (JNK) signaling pathway in neuroprotective mechanism. In particular, the JNK signaling pathway emerges as a possible target for brain repair after stroke. METHODS Cerebral I/R injury was produced in SD rat by using the middle cerebral artery occlusion model for 90 min, followed by 24h reperfusion. Postconditioning by inhalation of isoflurane was performed at different concentrations (1.5%, 3.0%, and 4.5%) for 1h after ischemia at the starting time point of reperfusion. The protective effect was tested by neurological deficit scoring with 2,3,5-triphenyl tetrazolium chloride and propidium iodide (PI) staining. Apoptosis of CA1 cells in the hippocampus was detected by TUNEL method. Expression levels of TGF-β1, Smad 2/3, p-Smad2/3, JNK, and p-JNK were determined by immunostaining and Western blot. RESULTS Postconditioning by isoflurane at 1.5% and 3.0% concentrations significantly decreased the neurobehavioral deficit scores and infarct volume compared with the I/R group, but no significant difference in neurobehavioral deficit score was detected between the I/R and 4.5% isoflurane postconditioning groups. Additionally, 1.5% isoflurane postconditioning decreased the numbers of PI-positive cells at 24h after reperfusion compared with the I/R group. TGF-β1 and p-Smad2/3 protein gradually increased after I/R injury, with the highest values observed in the 1.5% and 3% isoflurane postconditioning groups. For Smad2/3 protein expression, no differences existed among all groups. After inducing the TGF-β/SMAD3 signaling pathway specific blocker (LY2157299), the neurological deficit scores increased, infarct volumes enlarged, apoptosis increased, and PI-positive CA1 cells in the hippocampus also increased. The expression levels of TGF-β1 and p-Smad2/3 proteins were downregulated. During the pre-injection of LY2157299, the expression levels of TGF-β1 and p-Smad2/3 decreased significantly, but compared with the sham group, the expression level of p-JNK significantly increased. When the injection of LY2157299 was abolished, the expression of p-JNK significantly decreased. The expression levels of p-JNK and TGF-β1 significantly decreased when LY2157299 and SP600125 were injected simultaneously. However, the protective effect mediated by SP600125 completely disappeared, and the role of LY2157299 became dominant. Compared with the sham group, the expression of TGF-β1 was almost unchanged by the injection of SP600125 alone, but the expression of p-JNK significantly decreased. CONCLUSIONS Up to 1.5% isoflurane can upregulate the expression of TGF-β1 and downregulate that of p-JNK, which significantly mitigated I/R injury, leading to cerebral injury. However, this protective effect was abrogated when the TGF-β1 signaling pathway was blocked by LY2157299. Overall, the present results provided valid evidence to demonstrate that TGF-β1 contributes to isoflurane postconditioning against cerebral I/R injury by inhibiting the JNK signaling pathway.

Abstract
ETHNOPHARMACOLOGY RELEVANCE Astragali Radix (AR) has been used for thousands years to treat ischemic stroke. Calycosin and its glycoside form calycosin-7-O-β-D-glucoside (CG) are two representative isoflavones in Astragali Radix. However, its neurological effects and related molecular mechanisms are largely unknown. The present study aims to evaluate the neuroprotective effects of CG on blood-brain barrier (BBB) integrity of ischemic brain tissue and explore the relevant signaling mechanisms. MATERIAL AND METHOD Male adult Sprague-Daweley rats were subjected to 2 h of middle cerebral artery occlusion (MCAO) plus 24 h or 14 days of reperfusion. CG (26.8 mg/kg) was intraperitoneally administered into the rats at 15 min before onset of ischemia. The neuroprotective effects of CG were evaluated by measuring infarct volume, histological damage and BBB permeability. Furthermore, the effects of CG on scavenging nitric oxide (NO), and modulating matrix metalloproteinases (MMPs) and caveolin-1 (cav-1) were investigated with in vitro cultured brain microvascular endothelial cells treated with NO donor or oxygen-glucose deprivation (OGD) and/or in vivo rat model of MCAO cerebral ischemia-reperfusion injury. RESULTS CG treatment significantly reduced infarct volume, histological damage and BBB permeability in the in vivo MCAO ischemia-reperfusion rat model. CG treatment remarkably inhibited the expression and activities of MMPs, and secured the expression of cav-1 and tight junction proteins in the microvessels isolated from ischemic rat cortex. Furthermore, CG was revealed to scavenge NO, inhibit the activities of MMP-2 and MMP-9, and attenuate cell death in the in vitro cultured brain microvascular endothelial cells under OGD condition. CONCLUSION CG could protect BBB integrity in experimental cerebral ischemia-reperfusion injury via regulating NO/cav-1/MMPs pathway.
