Abstract
Phosphocreatine (PCr), a naturally occurring creatine phosphorylated molecule, is a high-energy phosphate compound that is one of the most important substances involved in cell energy metabolism, and also has anti-apoptosis and anti-oxidative stress effects. It is precisely because of its role in maintaining energy homeostasis that PCr is widely used in diseases related to energy damage. In the regulation of cell signal, PCr mainly plays a role through MAPK, NF-κB, PI3K/AKT, ERK/Nrf2/HO-1 and JAK2/STAT3. In clinical applications, PCr is commonly used as a cardioprotective drug, such as ischemic heart disease, myocardial fibrosis, myocardial infarction, arrhythmia, and myocarditis. In recent years, further research on PCr has found that PCr also has a positive role in the treatment of other diseases, including diabetes-induced liver injury, kidney injury, cerebral ischemia-reperfusion injury, and neurodegenerative diseases. In this paper, the literature on PCr in three databases, Web of Sciences, SciFinder, and PubMed, was summarized and analyzed, and the research progress of PCr in recent years was reviewed, hoping to provide help for the expansion of its application in clinical therapy.

Abstract
Aim. To study the effect of simultaneous administration of creatine phosphate immediately before ischemia on cardiodynamic parameters and biomarkers of oxidative stress in the coronary venous blood flow during retrograde perfusion in an isolated rat heart.Materials and methods. 20 Wistar albino rats were divided into 2 groups: group 1 (control) and group 2 (experimental), 10 rats per group. Cannulation and retrograde perfusion of aorta of an isolated rat heart with Krebs–Henseleit buffered solution by Landendorff was performed. Both groups underwent ischemia-reperfusion injury, which included global ischemia for 20 minutes followed by reperfusion for 30 minutes. The group 2 (experimental) was preconditioned with creatine phosphate at a dose of 0.2 mmol/l for 5 min before ischemia. We registered cardiodynamic parameters and indicators of oxidative stress at the point of stabilization, at the 1st and 30th minutes of reperfusion.Results. With the impact of creatine phosphate at the 30th minute of reperfusion in the group 2 in comparison with group 1, there was found an increase in the maximum and minimum speed of pressure elevation in the left ventricle (1.7 and 1.9 times, respectively), and of systolic and diastolic pressure in the left ventricle (1.5 and 1.6 times, respectively). Biomarkers of oxidative stress (lipid peroxidation index, nitrites, superoxide anion radical and hydrogen peroxide) were also statistically significantly lower in the group 2 after the 1st minute of reperfusion (by 1.2 times, by 1.4 times, by 2.8 times and 1.9 times, respectively), and after the 30th minute (1.3 times, 2.1 times, 1.9 times and 2.1 times, respectively).Conclusion. The administration of creatine phosphate into the coronary flow 5 minutes before the onset of ischemia has a protective effect on myocardial contractility. Reduction of oxidative stress and damage can be considered as a protective effect of creatine phosphate.

Abstract
Abstract
The present study strives to assess the cardioprotective role of phosphocreatine as an agent for postconditioning and perconditioning of isolated rat heart.
Rat hearts (n=30) were perfused with a Langendorff apparatus and randomly assigned to three groups subjected to 20 minutes of global ischemia and 30 minutes of reperfusion: control group (untreated rat hearts), postconditioning group (hearts treated with 0.2 mmol/l of phosphocreatine during the first 5 minutes of reperfusion), and perconditioning group (hearts treated with 0.2 mmol/l of phosphocreatine during the first 5 minutes of ischemia). During the experimental protocol, cardiodynamic parameters were evaluated, while oxidative stress parameters such as superoxide anion radical, hydrogen peroxide, nitrites and index of lipid peroxidation were determined in coronary venous effluent.
Postconditioning and perconditioning with phosphocreatine improved contractile function, heart rate and coronary flow, while the examined oxidative stress parameters in coronary venous effluent were significantly reduced in groups of treated rat hearts. The results of this study indicate that phosphocreatine has the potential as a therapeutic agent for perconditioning and postconditioning the heart in ischemia reperfusion injury.

Abstract
The aim of this study was to examine and compare the influence of preconditioning, perconditioning and postconditioning with creatine phosphate (PCr) on functional recovery and production of prooxidants of isolated rat heart subjected to ex vivo I-R injury on Langendorff apparatus. Wistar albino rats (male, n=40) were divided into 4 groups: control, and groups in which PCr (0.5mmol/l, 5 minutes) was perfused before (Pre group), after (Post group) or during (Per group) ex vivo induced ischemia. PCr application was associated with the great benefits on preserving cardiac contractility (in Pre group 100.96% for +(dP/dt max), 97.61.% for -(dP/dt max), in Per group 96.72% for +(dP/dt max), 95.60.% for -(dP/dt max) and in Post group 143.84% for +(dP/dt max), 104.36% for -(dP/dt max) in relation to the stabilization). In addition, PCr application prevented the rise of pro-oxidative markers during I-R injury in all therapeutic modalities. The most intensive benefits in the current investigation were observed when PCr was applied during the period of ischemia because the lowest fluctuations in the parameters of cardiac function and oxidative stress were observed. Overall, the results of this study highlight PCr-induced cardioprotection with promising prospects for future clinical use.

Abstract
Ischemic stroke (IS) is a major cause of mortality and disability worldwide. However, the pathogenesis of IS remains unknown, and methods for early prediction and diagnosis of IS are lacking. Metabolomics can be applied to biomarker discovery and mechanism exploration of IS by exploring metabolic alterations. In this review, 62 IS metabolomics studies in the murine model published from January 2006 to December 2020 in the PubMed and Web of Science databases were systematically reviewed. Twenty metabolites (e.g., lysine, phenylalanine, methionine, tryptophan, leucine, lactate, serine, N-acetyl-aspartic acid, and glutathione) were reported consistently in more than two-third murine studies. The disturbance of metabolic pathways, such as arginine biosynthesis; alanine, aspartate and glutamate metabolism; aminoacyl-tRNA biosynthesis; and citrate cycle, may be implicated in the development of IS by influencing the biological processes such as energy failure, oxidative stress, apoptosis, and glutamate toxicity. The transient middle cerebral artery occlusion model and permanent middle cerebral artery occlusion model exhibit both common and distinct metabolic patterns. Furthermore, five metabolites (proline, serine, LysoPC (16:0), uric acid, glutamate) in the blood sample and 7 metabolic pathways (e.g., alanine, aspartate, and glutamate metabolism) are shared in animal and clinical studies. The potential biomarkers and related pathways of IS in the murine model may facilitate the biomarker discovery for early diagnosis of IS and the development of novel therapeutic targets.

Abstract
Crystalline lens and striated muscle exist at opposite ends of the metabolic spectrum. Lens is a metabolically quiescent tissue, whereas striated muscle is a mechanically dynamic tissue with high-energy requirements, yet both tissues contain millimolar levels of ATP (>2.3 mM), far exceeding their underlying metabolic needs. We explored intracellular concentrations of ATP across multiple cells, tissues, species, and domains to provide context for interpreting lens/striated muscle data. Our database revealed that high intracellular ATP concentrations are ubiquitous across diverse life forms including species existing from the Precambrian Era, suggesting an ancient highly conserved role for ATP, independent of its widely accepted view as primarily "metabolic currency". Our findings reinforce suggestions that the primordial function of ATP was non-metabolic in nature, serving instead to prevent protein aggregation.

Abstract
If mitochondrial energy availability or oxidative metabolism is altered, patients will suffer from insufficient energy supply Phosphocreatine (PCr) not only acts as an energy carrier, but also acts as an antioxidant and defensive agent to maintain the integrity and stability of the membrane, to maintain ATP homeostasis through regulating mitochondrial respiration. Meanwhile, PCr can enhance calcium balance and reduce morphological pathological changes, ultimately, PCr helps to reduce apoptosis. On the other aspect, the activities of ATP synthase and MitCK play a crucial role in the maintenance of cellular energy metabolic function. It is interesting to note, PCr not only rises the activities of ATP synthase as well as MitCK, but also promotes these two enzymatic reactions. Additionally, PCr can also inhibit mitochondrial permeability transition in a concentration-dependent manner, prevent ROS and CytC from spilling into the cytoplasm, thereby inhibit the release of proapoptotic factors caspase-3 and caspase-9, and eventually, effectively prevent LPS-induced apoptosis of cells. Understandably, PCr prevents the apoptosis caused by abnormal mitochondrial energy metabolism and has a protective role in a non-energy manner. Moreover, recent studies have shown that PCr protects cell survival through PI3K/Akt/eNOS, MAPK pathway, and inhibition of Ang II-induced NF-κB activation. Furthermore, PCr antagonizes oxidative stress through the activation of PI3K/Akt/GSK3b intracellular pathway, PI3K/AKT-PGC1α signaling pathway, while through the promotion of SIRT3 expression to maintain normal cell metabolism. Interestingly, PCr results in delaying the time to enter pathological metabolism through the delayed activation of AMPK pathway, which is different from previous studies, now we propose the hypothesis that the "miRNA-JAK2/STAT3 -CypD pathway" may take part in protecting cells from apoptosis, PCr may be further be involved in the dynamic relationship between CypD and STAT3. Furthermore, we believe that PCr and CypD would be the central link to maintain cell survival and maintain cell stability and mitochondrial repair under the mitochondrial dysfunction caused by oxidative stress. This review provides the modern progress knowledge and views on the molecular mechanism and molecular targets of PCr in a non-energy way.

Abstract
PURPOSE Cerebral ischemia is the main cause of permanent adult disabilities worldwide. This study investigated the reparative effects and potential mechanisms of methylphenidate (MPH), a medication for the treatment of attention-deficit/hyperactivity disorder. METHODS In vitro oxygen-glucose deprivation/reperfusion (OGD/R) and in vivo cerebral ischemia-reperfusion models were established. Sprague-Dawley (SD) rats were randomly divided into four groups (n = 20): Sham, Model, and MPH (0.5 and 1 mg/kg). Rats in MPH groups were treated with 0.5 or 1 mg/kg MPH via intraperitoneal injection for 7 days. Rats in the Sham and Model groups were treated with PBS during the same period. Cell viability was measured using MTT assay. Apoptosis was detected by Annexin V/PI staining. Protein expression was detected by Western blot. The volume of cerebral infarction was detected by triphenyltetrazolium chloride (TTC) staining. The DNA damage in ischemic brain tissues was detected by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. RESULTS MPH treatment significantly reduced OGD/R-induced cell damage, shown by the increased cell viability and decreased apoptotic rate. p-AMPK and p-ACC protein expression increased in the OGD/R model after MPH treatment. The addition of AMPK inhibitor largely abolished the neuroprotective effects of MPH, evidenced by the reduced cell viability, increased apoptotic rate, and decreased protein expression of p-AMPK as well as p-ACC. Moreover, MPH treatment significantly alleviated the cerebral ischemia-reperfusion injury and decreased apoptosis in brain tissues, which may be associated with the AMPK/ACC pathway. CONCLUSIONS MPH exerted protective activities against oxidative stress in the OGD/R model and ameliorated brain damage of rats in the middle cerebral artery occlusion model, at least in part, through activating the AMPK pathway. These data demonstrated neuroprotective properties of MPH and highlighted it as a potential therapeutic agent against cerebral ischemia-reperfusion injury.

Abstract
Objectives To verify the protective effect of phosphocreatine on myocardium in an ischemic model and the possible mechanism of action. Methods The model of myocardial ischemia/reperfusion (I/R) was established by the ligation balloon method. 30 SD rats were randomly divided into three groups, n = 10 in each group. Sham operation group: the coronary artery was not blocked and observed for 120 minutes. The ischemia/reperfusion (I/R) group was given ischemia for 30 minutes and ischemia reperfusion for 90 minutes. Phosphocreatine (PCr) group: after 30 minutes of ischemia, the rats were intraperitoneally injected with PCr (200 mg/kg) for 90 minutes. The animal groups of myocardial ischemia/reperfusion model in vitro were the same as those in vivo. The heart was removed by thoracotomy and washed immediately in H-K buffer solution. Then, the heart was installed on the Langendorff instrument. The concentration of PCr perfusion fluid in the PCr group was 10 mmol/L. The changes in coronary blood flow in isolated myocardium were recorded. The heart rate and electrocardiogram were recorded by RM6240BT. At the end of the experiment, myocardial pathological sections and Cx43 immunofluorescence staining were made, and the contents of malondialdehyde (MDA) in myocardial tissue were detected. Results Phosphocreatinine treatment improved the myocardial ischemia model, performance in electrocardiogram (ECG) changes (ST segment apparent), and histological changes (decrease in necrotic myocardial cells, inflammatory cell infiltration, and a reduction in myocardial edema). At the same time, MDA decreased, while coronary blood flow and Cx43 expression significantly improved. Conclusions Phosphocreatine can improve the electrocardiogram and restore histologic changes in ischemic myocardium and coronary blood flow. The postulated mechanism is by inhibiting the generation of free oxygen radicals and restoring the expression of Cx43 protein.

Abstract
Cerebral ischemia/reperfusion (I/R) injuries are common and often cause severe complications. Ozone has been applied for protecting I/R injury in animal models of several organs including cerebra, but the detailed mechanism remains unclear. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and lactate dehydrogenase measurement were used to determine the influence of ozone on cell activity and damage of SH-SY5Y cells. Some redox items such as catalase (CAT), malondialdehyde (MDA), glutathione peroxidase (GSH-Px), and superoxide dismutase (SOD) were measured by enzyme-linked immunosorbent assay. The mitochondrial membrane potential (ΔΨm ) was determined by JC-1 assay. Cytochrome-c (cyt-c) level in the cytoplasm and mitochondrion was measured by western blotting. Apoptosis was determined by flow cytometry, and some apoptosis-related molecules were detected by quantitative real-time polymerase chain reaction and western blotting. Ozone alleviated oxidative damage by increasing GSH-Px, SOD, CAT, and decreasing MDA. Ozone decreased mitochondrial damage caused by I/R injury and inhibited the release of cyt-c from mitochondrion to cytoplasm in SH-SY5Y cells. The cell apoptosis caused by I/R was inhibited by ozone, and ozone could decrease apoptosis by increasing the ratio of Bcl-2/Bax and inhibiting caspase signaling pathway in SH-SY5Y cells. Ozone has the ability of maintaining redox homeostasis, decreasing mitochondrion damage, and inhibiting neurocytes apoptosis induced by I/R. Therefore, ozone may be a promising protective strategy against cerebral I/R injury.

Is there an effect of ischemic conditioning on myocardial contractile function following acute myocardial ischemia/reperfusion injury? Biochim Biophys Acta Mol Basis Dis 2019; 1865:822-830. [PMID: 30660684 DOI: 10.1016/j.bbadis.2018.12.020] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2018] [Revised: 12/18/2018] [Accepted: 12/19/2018] [Indexed: 10/27/2022]
Abstract
Ischemic conditioning induces cardioprotection; the final infarct size following a myocardial ischemic event is reduced. However, whether ischemic conditioning has long-term beneficial effects on myocardial contractile function following such an ischemic event needs further elucidation. To date, ex vivo studies have shown that ischemic conditioning improves the contractile recovery of isolated ventricular papillary muscle or atrial trabeculae following simulated ischemia. However, in vivo animal studies and studies in patients undergoing elective cardiac surgery show conflicting results. At the subcellular level, it is known that ischemic conditioning improved energy metabolism, preserved mitochondrial respiration, ATP production, and Ca2+ homeostasis in isolated mitochondria from the myocardium. Ischemic conditioning also presents with post-translational modifications of proteins in the contractile machinery of the myocardium. The beneficial effects on myocardial contractile function need further elucidation.

The creatine kinase system as a therapeutic target for myocardial ischaemia-reperfusion injury. Biochem Soc Trans 2018; 46:1119-1127. [PMID: 30242115 PMCID: PMC6195634 DOI: 10.1042/bst20170504] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2018] [Revised: 08/18/2018] [Accepted: 08/22/2018] [Indexed: 12/13/2022]
Abstract
Restoring blood flow following an acute myocardial infarction saves lives, but results in tissue damage due to ischaemia–reperfusion injury (I/R). Ameliorating this damage is a major research goal to improve recovery and reduce subsequent morbidity due to heart failure. Both the ischaemic and reperfusion phases represent crises of cellular energy provision in which the mitochondria play a central role. This mini-review will explore the rationale and therapeutic potential of augmenting the creatine kinase (CK) energy shuttle, which constitutes the primary short-term energy buffer and transport system in the cardiomyocyte. Proof-of-principle data from several transgenic mouse models have demonstrated robust cardioprotection by either raising myocardial creatine levels or by overexpressing specific CK isoforms. The effect on cardiac function, high-energy phosphates and myocardial injury will be discussed and possible directions for future research highlighted. We conclude that the CK system represents a viable target for therapeutic intervention in I/R injury; however, much needed translational studies will require the development of new pharmacological tools.

Abstract
We performed metabolomic analyses of mouse brain using a transient middle cerebral artery occlusion (tMCAO) model with Matrix Assisted Laser Desorption/Ionization (MALDI)-mass spectrometry imaging (MSI) to reveal metabolite changes after cerebral ischemia. We selected and analyzed three metabolites, namely creatine (Cr), phosphocreatine (P-Cr), and ceramides (Cer), because these metabolites contribute to cell life and death. Eight-week-old male C57BL/6J mice were subjected to tMCAO via the intraluminal blockade of the middle cerebral artery (MCA) and reperfusion 60 min after the induction of ischemia. Each mouse was randomly assigned to one of the three groups; the groups were defined by the survival period after reperfusion: control, 1 h, and 24 h. Corrected samples were analyzed using MALDI-MSI. Results of MSI analysis showed the presence of several ionized substances and revealed spatial changes in some metabolites identified as precise substances, including Cr, P-Cr, Cer d18:1/18:0, phosphatidylcholine, L-glutamine, and L-histidine. Cr, P-Cr, and Cer d18:1/18:0 were changed after tMCAO, and P-Cr and Cer d18:1/18:0 accumulated over time in ischemic cores and surrounding areas following ischemia onset. The upregulation of P-Cr and Cer d18:1/18:0 was detected 1 h after tMCAO when no changes were evident on hematoxylin and eosin staining and immunofluorescence assay. P-Cr and Cer d18:1/18:0 can serve as neuroprotective therapies because they are biomarker candidates for cerebral ischemia.

Abstract
Phosphocreatine (PCr) plays an important role in the energy metabolism of the heart and a decrease in its intracellular concentration results in alteration of myocardium energetics and work. We conducted a meta-analysis of all randomized and matched trials that compared PCr with placebo or standard treatment in patients with coronary artery disease or chronic heart failure or in those undergoing cardiac surgery. We systematically searched PubMed/Medline, Embase, Cochrane Central Register of Controlled Trials and Google Scholar up to 1 November 2015, for pertinent trials. The primary outcome was all-cause mortality. Secondary outcomes included inotrope use, ejection fraction (EF), peak creatinine kinase-myocardial band (CK-MB) release and the incidence of major arrhythmias, as well as spontaneous recovery of the heart performance in the subgroup of patients undergoing cardiac surgery with cardiopulmonary bypass. We pooled odds ratio (OR) and mean difference (MD) using fixed- and random effects models. We identified 41 controlled trials, of them 32 were randomized. Patients receiving PCr had lower all-cause mortality when compared with the control group [61/1731 (3.5%) vs 177/1667 (10.6%); OR: 0.71, 95% CI: 0.51-0.99; P = 0.04; I(2) = 0%; with 3400 patients and 22 trials included]. Phosphocreatine administration was associated with higher LVEF (MD: 3.82, 95% CI: 1.18-6.46; P = 0.005; I(2) = 98%), lower peak CK-MB release (MD: -6.08, 95% CI: -8.01, -4.15; P < 0.001; I(2) = 97%), lower rate of major arrhythmias (OR: 0.42; 95% CI: 0.27-0.66; P < 0.001; I(2) = 0%), lower incidence of inotropic support (OR: 0.39, 95% CI: 0.25-0.61; P < 0.001; I(2) = 56%) and a higher level of spontaneous recovery of the heart performance after cardiopulmonary bypass (OR: 3.49, 95% CI: 2.28-5.35; P < 0.001; I(2) = 49%) when compared with the control group. In a mixed population of patients with coronary artery disease, chronic heart failure or in those undergoing cardiac surgery, PCr may reduce all-cause short-term mortality. In addition, PCr administration was associated with improved cardiac outcomes. Owing to the pharmacological plausibility of this effect and to the concordance of the beneficial effects of PCr on several secondary but important outcomes and survival, there is urgent need for a large multicentre randomized trial to confirm these findings.

Abstract
UNLABELLED Henoch-Schönlein purpura (HSP) is a small-vessel disease in children that is often accompanied by kidney damage. Despite many efforts to improve the early assessment of renal injury in HSP patients, effective markers are still lacking. In recent years, the relationship between kidney injury molecule-1 (KIM-1) and tubulointerstitial injury has drawn much attention, especially regarding the diagnostic potential of serum and urinary KIM-1 levels. However, the diagnostic value of KIM-1 for detecting urinary kidney injury in HSP patients is still elusive. Furthermore, the treatment of Henoch-Schönlein purpura nephritis (HSPN) relies on the clinician's experience without performing renal biopsy, so it is important to find an effective biomarker and therapy. In the present study, we investigated the diagnostic value of urinary KIM-1 for early renal injury in HSP patients enrolled in a prospective, single-center study. Urinary KIM-1 levels were measured in 27 patients with HSP, 32 patients with HSPN (21 HSPN patients had undergone renal biopsy), and 16 healthy donors, as normal controls. The HSPN patients were randomly divided to receive either routine therapy (n = 13) or routine treatment combined with creatine phosphate sodium (CP) (n = 19). Urinary KIM-1 levels were significantly greater in the HSP and HSPN groups than those in the healthy control group (P < 0.01), and were significantly greater in the HSPN group than in the HSP group (P < 0.01). The urinary KIM-1 levels decreased significantly after 10-14 days of treatment with CP compared with conventional therapy (P < 0.05). CONCLUSION Our results demonstrate the diagnostic value of KIM-1 and the therapeutic potential of CP for early renal damage in HSP patients. WHAT IS KNOWN Urine kidney injury molecule-1 (KIM-1) is a sensitive biomarker for tubulointerstitial injury. Henoch-Schonlein purpura (HSP) usually presents with renal damage. WHAT IS NEW Our results suggest that the urinary KIM-1 level is a sensitive and specific biomarker for the detection of early renal damage in HSP and may predict the severity of HSP and HSPN. The administration of creatine phosphate sodium (CP) may reduce urinary KIM-1 levels and thus correct the hypoxic condition of the kidney. Preconditioning with CP may also be a useful adjunct for preventing early renal damage in HSPN patients.

Abstract
Apelin-13 inhibits neuronal apoptosis caused by hydrogen peroxide, yet apoptosis following cerebral ischemia-reperfusion injury has rarely been studied. In this study, Apelin-13 (0.1 μg/g) was injected into the lateral ventricle of middle cerebral artery occlusion model rats. TTC, TUNEL, and immunohistochemical staining showed that compared with the cerebral ischemia/reperfusion group, infarct volume and apoptotic cell number at the ischemic penumbra region were decreased in the Apelin-13 treatment group. Additionally, Apelin-13 treatment increased Bcl-2 immunoreactivity and decreased caspase-3 immunoreactivity. Our findings suggest that Apelin-13 is neuroprotective against cerebral ischemia/reperfusion injury through inhibition of neuronal apoptosis.

Abstract
Abstract Ozone (O3) has been viewed as a novel treatment for different diseases in these years and oxidative stress and apoptosis play a key role in the pathogenesis of kidney diseases including renal ischemia and reperfusion (I/R). In the present study, we investigated the role of ozone oxidative preconditioning (OzoneOP) in attenuating oxidative stress and apoptosis in a hypoxia/reoxygenation (H/R) injury model using rat kidney cells. We induced H/R injury in kidney cells treated with or without OzoneOP. Oxidative stress parameters such as superoxide dismutase (SOD), malondialdehyde (MDA) and lactate dehydrogenase (LDH) were determined, as well as some apoptotic proteins. We observed that oxidative stress and apoptosis were increased in H/R group compared to OzoneOP group; however, these changes were significantly decreased by the treatment with OzoneOP. We concluded that OzoneOP can protect the kidney cells against H/R injury and its mechanism may be through the reduction of oxidative stress and apoptosis.

Abstract
Ischemia-reperfusion is a common injury of clinical ischemic disease and surgical lesions. Ischemic postconditioning (IPO) improves the ability of organs subjected to ischemia to tolerate injury. However, renal IPO studies have been based on animal models. In order to gain insights into IPO-induced alterations at the cellular level, an in vitro model for IPO was designed using the rat proximal tubular cell line NRK-52E. This model was established by placing NRK-52E cells in ischemic conditions for 3 h, then exposing cells to three cycles of reperfusion for 10 min and finally to ischemic conditions for 10 min (postconditioning). The cells were cultured further in reperfusion conditions for 3, 6, 12 and 24 h. Flow cytometry and Hoechst were used to assess apoptosis. The protein expression of B-cell lymphoma 2 (Bcl-2), Bcl-2-associated X protein (Bax), caspase-3, cleaved caspase-3 and caspase-8 were analyzed by western blotting. The results demonstrated that apoptosis occurred in cells subjected to ischemia/reperfusion (I/R) alone or with postconditioning following reperfusion for 24 h. Cells subjected to I/R demonstrated increased expression of Bax, cleaved caspase-3 and caspase-8 at the end of reperfusion. However, the levels of Bax, cleaved caspase-3 and caspase-8 were significantly attenuated in cells, which had undergone IPO. In conclusion, apoptosis was observed in cells subjected to 3 h of ischemia-reperfusion injury and IPO was able to inhibit this apoptosis. IPO inhibited apoptosis by inhibiting the caspase pathway thereby exerting protective effects.

Abstract
Background The aim of the study was to investigate the effects of phosphocreatine (PCr) post-treatment combined with ischemic post-conditioning on myocardial ischemia/reperfusion (I/R) injury in a rat model. Methods Forty Sprague-Dawley rats that had undergone 30 minutes ischemia and 120 minutes reperfusion were randomly divided into four groups (n = 10 in each group): the I/R group, the ischemia post-conditioning (IPost) group, the PCr group, and the IPost + PCr group. The activities of serum creatine kinase (CK), myeloperoxidase (MPO), and lactate dehydrogenase (LDH) were measured after 120 minutes of reperfusion. At the end of the experiment, serum levels of nuclear factor (NF)-κB and tumor necrosis factor (TNF)-α were detected, myocardial infarct size (IS) was measured by triphenyltetrazolium chloride staining, and myocardial expression of Bcl-2 and phosphorylated Akt (p-Akt) was determined by western blot. Results The IPost, PCr, and PCr + IPost groups had significantly lower IS than the I/R group (P < 0.05). The reductions in CK, LDH, and MPO release were consistent with the decrease in the myocardial IS (P < 0.05). Serum concentrations of TNF-α and NF-κB in the IPost, PCr, and PCr + IPost groups were significantly lower than those in the I/R group (P < 0.05). The levels of p-Akt and Bcl-2 in the IPost, PCr, and PCr + IPost groups were greater than those in the I/R group (P < 0.05). CK, LDH, MPO, NF-κB, TNF-α, p-Akt, Bcl-2 and IS were further enhanced in the IPost + PCr group (P < 0.05). Conclusions Post-treatment with PCr enhanced the protective effect of IPost on rat myocardium affected by I/R injury, possibly by inhibiting the inflammatory response and activating the phosphatidylinositol 3-kinase (PI-3K)/Akt/Bcl-2 signaling pathway.

Abstract
Renal ischemia and reperfusion (I/R) injury, which commonly occurs in kidney transplantation, is the leading cause of acute kidney injury. Picroside II possesses a wide range of pharmacological effects, including anti-apoptosis effects. In the present study, the ability of picroside II to attenuate apoptosis in a rat model of renal I/R injury was investigated. Sprague-Dawley rats were subjected to 45 min of ischemia followed by 24 h of reperfusion. Prior to reperfusion, the rats were treated with picroside II or an equal volume of phosphate-buffered saline. It was observed that renal function was significantly improved by the treatment with picroside II. Morphological analysis indicated that picroside II markedly reduced tissue damage and the expression of cleaved caspase-3. Reverse transcription-quantitative polymerase chain reaction and western blotting revealed that the expression levels of Bax and poly(ADP-ribose) polymerase-1 (PARP-1) were upregulated in the I/R group, whereas those of Bcl-2 were downregulated. However, the treatment with picroside II inhibited these changes induced by renal I/R injury. In conclusion, picroside II has potent anti-apoptotic activity against renal I/R injury.

Abstract
This study aimed to investigate the effects of lactuside B (LB) on aquaporin-4 (AQP4) and caspase-3 mRNA expression in the hippocampus and the striatum following cerebral ischaemia-reperfusion (I/R) injury in rats. Cerebral I/R injury was established in Sprague-Dawley rats by occluding the middle cerebral artery for 2 h and then inducing reperfusion. Rats in the I/R + LB groups were treated with various doses of LB following reperfusion. Neurological deficit scores and brain water content were obtained to determine the pharmacodynamics of LB. Reverse transcription polymerase chain reaction was performed to determine the expression levels of AQP4 and caspase-3 mRNA in the hippocampus and the striatum. The results of the present study indicate that LB decreased the neurological deficit scores and the brain water content. In the hippocampus, AQP4 and caspase-3 mRNA expression levels were significantly downregulated in the I/R + LB groups at 24 and 72 h following drug administration, compared with those in the I/R group (P<0.05). In the striatum, LB was also shown to significantly reduce AQP4 and caspase-3 mRNA expression levels at 24 and 72 h following drug administration, compared with those in the I/R group (P<0.05). The effects became stronger as the LB dose was increased. The most significant reductions in AQP4 and caspase-3 mRNA expression were noted in the I/R + LB 25 mg/kg and I/R + LB 50 mg/kg groups at 72 h following drug administration. The results of the present study show that LB is capable of significantly downregulating AQP4 and caspase-3 mRNA expression in the hippocampus and striatum following cerebral I/R injury in rats. The mechanism by which LB improved ischaemic brain injury may be associated with changes in AQP4 and caspase-3 mRNA expression in the hippocampus and the striatum.

Abstract
Recently we described an ischemic preconditioning induced by repetitive coronary stenosis, which is induced by 6 episodes of non-lethal ischemia over 3 days, and which also resembles the hibernating myocardium phenotype. When compared with traditional second window of ischemic preconditioning using cDNA microarrays, many genes which differed in the repetitive coronary stenosis appeared targeted to metabolism. Accordingly, the goal of this study was to provide a more in depth analysis of changes in metabolism in the different models of delayed preconditioning, i.e., second window and repetitive coronary stenosis. This was accomplished using a metabolomic approach based on liquid chromatography-mass spectrometry (LC-MS) and gas chromatography-mass spectrometry (GC-MS) techniques. Myocardial samples from the ischemic section of porcine hearts subjected to both models of late preconditioning were compared against sham controls. Interestingly, although both models involve delayed preconditioning, their metabolic signatures were radically different; of the total number of metabolites that changed in both models (135 metabolites) only 7 changed in both models, and significantly more, p<0.01, were altered in the repetitive coronary stenosis (40%) than in the second window (8.1%). The most significant changes observed were in energy metabolism, e.g., phosphocreatine was increased 4 fold and creatine kinase activity increased by 27.2%, a pattern opposite from heart failure, suggesting that the repetitive coronary stenosis and potentially hibernating myocardium have enhanced stress resistance capabilities. The improved energy metabolism could also be a key mechanism contributing to the cardioprotection observed in the repetitive coronary stenosis and in hibernating myocardium. This article is part of a Special Issue entitled "Focus on Cardiac Metabolism".

Abstract
Phosphocreatine (PCr) is a natural compound, which can donate high-energy phosphate group to ADP to synthesize ATP, even in the absence of oxygen and glucose. At present, it is widely used in cardiac and renal ischemia-reperfusion (IR) disease. In this study, to examine the protective efficacy of PCr against cerebral IR, disodium creatine phosphate was injected intravenously into rats before focal cerebral IR. Intracranial pressure (ICP), neurological score, cerebral infarction volume, and apoptotic neurons were observed. Expression of caspase-3 and aquaporin-4 (AQP4) was analyzed. Compared with IR group, rats pretreated with PCr had better neurologic score, less infarction volume, fewer ultrastructural histopathologic changes, reduced apoptosis, and lower aquaporin-4 level. In conclusion, PCr is neuroprotective after transient focal cerebral IR injury. Such a protection might be associated with apoptosis regulating proteins.

Abstract
Phosphocreatine (PCr) is an endogenous compound containing high-energy phosphate bonds. It has been confirmed that PCr is effective in preventing and treating cardiac and renal ischemia-reperfusion injury. In this study, rat cerebral ischemia-reperfusion injury models were constructed. Apoptotic cells in the cortex region were measured by TUNEL method. Malondialdehyde (MDA) content was detected by chromatometry, and calmodulin (CaM) activity was detected by ELISA. Compared with sham-operated group (sham group), TUNEL-positive cells, MDA, and level of CaM activity increased in ischemia-reperfusion group (I/R group) and PCr preconditioning group (PCr group); compared with I/R group, TUNEL-positive cells, MDA content, and level of CaM activity decreased in PCr group. This study indicated that PCr can decrease the morphological damage and the neuron apoptosis of the ischemia-reperfusion injury brain through attenuating abnormalities of calcium balance and production of oxygen free radicals.

Abstract
OBJECTIVES The purpose of this pilot study was to determine whether there are markers that can be used to study the effects of grounding on delayed-onset muscle soreness (DOMS). DESIGN AND SUBJECTS Eight (8) healthy subjects were exposed to an eccentric exercise that caused DOMS in gastrocnemius muscles of both legs. Four (4) subjects were grounded with electrode patches and patented conductive sheets connected to the earth. Four (4) control subjects were treated identically, except that the grounding systems were not connected to the earth. OUTCOME MEASURES Complete blood counts, blood chemistry, enzyme chemistry, serum and saliva cortisols, magnetic resonance imaging and spectroscopy and pain levels were taken at the same time of day before the eccentric exercise and 24, 48, and 72 hours afterwards. Parameters consistently differing by 10% or more, normalized to baseline, were considered worthy of further study. RESULTS Parameters that differed by these criteria included white blood cell counts, bilirubin, creatine kinase, phosphocreatine/inorganic phosphate ratios, glycerolphosphorylcholine, phosphorylcholine, the visual analogue pain scale, and pressure measurements on the right gastrocnemius. CONCLUSIONS In a pilot study, grounding the body to the earth alters measures of immune system activity and pain. Since this is the first intervention that appears to speed recovery from DOMS, the pilot provides a basis for a larger study.

In vivo neuroprotection by a creatine-derived compound: phosphocreatine-Mg-complex acetate. Brain Res 2009; 1285:158-63. [PMID: 19523930 DOI: 10.1016/j.brainres.2009.06.009] [Citation(s) in RCA: 24] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2009] [Revised: 06/04/2009] [Accepted: 06/05/2009] [Indexed: 11/20/2022]
Abstract
Phosphocreatine-Mg-complex acetate (PCr-Mg-CPLX) is a creatine-derived compound that in previous in vitro research was able to increase neuronal creatine independently of the creatine transporter, thus providing hope to cure the hereditary syndrome of creatine transporter deficiency. In previous research we showed that it reproduces in vitro the known neuroprotective effect of creatine against anoxic damage. In the present paper we investigated if PCr-Mg-CPLX reproduces this neuroprotective effect in vivo, too. We used a mouse model of transient middle cerebral artery occlusion. Mice received PCr-Mg-CPLX or a mixture of the two separate compounds phosphocreatine (PCr) and MgSO(4), or vehicle. The injections were done 60 min and 30 min before ischemia. Forty-eight hours after ischemia neurological damage was evaluated with Clark's behavioural tests, then the infarct volume was measured. PCr-Mg-CPLX reduced the infarct volume by 48%, an effect that was not duplicated by the separate administration of PCr and MgSO(4) and the neurological damage was decreased in a statistically significant way. We conclude that PCr-Mg-CPLX affords in vivo neuroprotection when administered before ischemia. These results are comparable to previous research on creatine administration in experimental stroke. PCr-Mg-CPLX maintains creatine-like neuroprotective effects in vivo as well as in vitro. Our study suggests that PCr-Mg-CPLX might have a therapeutic role in the treatment of hereditary creatine transporter deficiency and of conditions where there is a high risk of impending stroke or cerebral ischemic damage, like high-risk transient ischemic attacks, open heart surgery, and carotid surgery.
