Abstract
With the growth of the food industry, fructose, the intake of which increases with food, causes obesity and metabolic syndrome. Kidney damage may develop from metabolic syndrome. Selenium (Se) participates in the structure of antioxidant enzymes and has a medicinal effect. In this work, the protective impact of Se on kidney damage produced by high-fructose corn syrup (HFCS) via endoplasmic reticulum (ER) stress was examined. The study comprised four groups, each consisting of ten experimental animals: control, HFCS (20%-HFCS), HFCS (20%-HFCS), + Se (0.3 mg/kg/day/po), and Se (0.3 mg/kg/day/po) alone. The duration of the experiment was 6 weeks. Kidney tissues were stained with hematoxylin and eosin for histological examination. Immunohistochemical analysis was conducted to assess TNF-α and caspase-3 levels. The spectrophotometric evaluation was performed to measure TOS (total oxidant status), TAS (total antioxidant status), and OSI (oxidative stress index) levels. The PERK, ATF4, CHOP, BCL-2, and caspase-9 gene expression levels were assessed by the RT-qPCR method. After Se treatment, histopathological abnormalities and TNF-α and caspase-3 levels in the HFCS+Se group decreased (p < 0.001). While TOS and OSI levels increased dramatically in the HFCS group, TAS values decreased significantly but improved after Se application (p < 0.001). The expression levels of the genes PERK, ATF4, CHOP, and caspase-9 were significantly lower in the HFCS group when compared to the HFCS+Se group (p < 0.05). Our findings suggest that Se may protect against ER stress, oxidative stress, apoptosis, and kidney damage caused by high-dose fructose consumption.

Abstract
Using selenium (Se) nanoparticles has received attention in recent years because of their therapeutic benefits due to their anticancer, antioxidant, anti-inflammatory, and anti-diabetic effects. This research was conducted to evaluate the possible protective impact of nano-Se on renal unilateral ischemia/reperfusion injury (uIRI) in adult male Wistar rats. Using clamping of the left renal pedicle within 45 min uIRI was induced. The animals were randomly divided into nine groups of control, nano-Se (0.25, 0.5, and 1 mg/kg bw/day) alone, uIRI control, and uIRI rats administrated with nano-Se. At 30 days after treatment, the animals were sacrificed to be assessed biochemically and histopathologically. Nano-Se in uIRI groups have significantly decreased serum creatinine, urea levels, renal histological damage, and increased antioxidant status. Also, our findings demonstrated that the administration of nano-Se caused a significant decrease in the immunoreactivity level of the epidermal growth factor (EGF) and EGFR expression (EGF receptor) in the renal tissue of the uIRI rats. Therefore, nano-Se possesses renoprotective effects, and this effect might be attributable to its antioxidant and free radical scavenger effects. These renoprotective effects may depend on the decreased EGF immunoreactivity level and EGFR expression in the kidney tissue and improve the structure of the kidney tissue. Thus, our research provided biochemical and histological data supporting the potential clinical use of nano-Se for the treatment of certain kidney disorders.

Abstract
Effects of selenoproteins on many renal diseases have been reported. However, their role in renal ischemia-reperfusion (I/R) injury is unclear. The present study was performed to investigate the impact of ebselen and renal I/R injury on the expression of selenoproteins. Sprague-Dawley rats were pretreated with or without ebselen (10 mg/kg) through a daily single oral administration from 3 days before renal I/R surgery. RT-qPCR (real-time quantitative PCR) was performed to determine the mRNA expression of 25 selenoprotein genes in the renal tissues. The expression levels of two selenoproteins, including GPX3 (glutathione peroxidase 3) and DIO1 (iodothyronine deiodinase 1), were evaluated by Western blot or/and IHF (immunohistofluorescence) assays. Furthermore, renal function, renal damage, oxidative stress, and apoptosis were assessed. The results showed that in renal I/R injury, the mRNA levels of 15 selenoprotein genes (GPX1, GPX3, GPX4, DIO1, DIO2, TXNRD2, TXNRD3, SEPHS2, MSRB1, SELENOF, SELENOK, SELENOO, SELENOP, SELENOS, and SELENOT) were decreased, whereas those of eight selenoprotein genes (GPX2, GPX6, DIO3, TXNRD1, SELENOH, SELENOM, SELENOV, and SELENOW) were increased. I/R also induced a reduction in the expression levels of GPX3 and DIO1 proteins. In addition, our results indicated that ebselen reversed the changes in those selenoprotein genes, excluding SELENOH, SELENOM, SELENOP, and SELENOT, in renal I/R injury and alleviated I/R-induced renal dysfunction, tissue damage, oxidative stress, and apoptosis. To our knowledge, this is the first study to investigate the changes of 25 mammalian selenoprotein genes in renal I/R injury kidneys. The present study also provided more evidence for the roles of ebselen against renal I/R injury.

Abstract
Renal ischemia/reperfusion (RI/R) is a critical clinical outcome with slightly reported improvement in mortality and morbidity. Effective therapies are still crucially required. Accordingly, the therapeutic effects of esculin (ESC, LCESI-MS/MS-isolated compound from Vachellia farnesiana flowers extract, with reported P2X7 receptor inhibitor activity) alone and in combination with erythropoietin (EPO) were investigated against RI/R injury and the possible underlying mechanisms were delineated. ESC and EPO were administered for 7 days and 30 min prior to RI, respectively. Twenty-four hour following reperfusion, blood and kidney samples were collected. Results revealed that pretreatment with either ESC or EPO reduced serum nephrotoxicity indices, renal oxidative stress, inflammatory, and apoptosis markers. They also ameliorated the renal histopathological injury on both endothelial and tubular epithelial levels. Notably, ESC markedly inhibited P2X7 receptors and NLRP3 inflammasome signaling (downregulated NLRP3 and Caspase-1 gene expressions), whereas EPO significantly upregulated PI3K and Akt gene expressions, also p-PI3K and p-Akt levels in renal tissues. ESC, for the first time, demonstrated effective protection against RI/R-injury and its combination with EPO exerted maximal renoprotection when compared to each monotherapy, thereby representing an effective therapeutic approach via inhibiting oxidative stress, inflammation, renal tubular and endothelial injury, apoptosis, and P2X7 receptors expression, and activating PI3K/Akt pathway.

Abstract
Renal ischemia-reperfusion (I/R) injury is one of the most common causes of chronic kidney disease (CKD). It brings unfavorable outcomes to the patients and leads to a considerable socioeconomic burden. The study of renal I/R injury is still one of the hot topics in the medical field. Ebselen is an organic selenide that attenuates I/R injury in various organs. However, its effect and related mechanism underlying renal I/R injury remains unclear. In this study, we established a rat model of renal I/R injury to study the preventive effect of ebselen on renal I/R injury and further explore the potential mechanism of its action. We found that ebselen pretreatment reduced renal dysfunction and tissue damage caused by renal I/R. In addition, ebselen enhanced autophagy and inhibited oxidative stress. Additionally, ebselen pretreatment activated the nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway. The protective effect of ebselen was suppressed by autophagy inhibitor wortmannin. In conclusion, ebselen could ameliorate renal I/R injury, probably by enhancing autophagy, activating the Nrf2 signaling pathway, and reducing oxidative stress.

Abstract
Purpose Selenium nanoparticles (SeNPs) have recently gained much attention in nanomedicine applications owing to their unique biological properties. Biosynthesis of SeNPs using nutraceuticals as lycopene (LYC) maximizes their stability and bioactivities. In this context, this study aimed to elucidate the renoprotective activity of SeNPs coated with LYC (LYC-SeNPs) in the acute kidney injury (AKI) model. Methods Rats were divided into six groups: control, AKI (glycerol-treated), AKI+sodium selenite (Na2SeO3; 0.5 mg/kg), AKI+LYC (10 mg/kg), AKI+LYC-SeNPs (0.5 mg/kg) and treated for 14 days. Results Glycerol treatment evoked significant increases in rhabdomyolysis-related markers (creatine kinase and LDH). Furthermore, relative kidney weight, Kim-1, neutrophil gelatinase-associated lipocalin (NGAL), serum urea, and creatinine in the AKI group were elevated. Glycerol-injected rats displayed declines in reduced glutathione level, and superoxide dismutase, catalase, glutathione peroxidase, and glutathione reductase activities, paralleled with downregulations in Nfe2l2 and Hmox-1 expressions and high renal MDA and NO contents. Glycerol-induced renal inflammation was evident by rises in TNF-α, IL-1β, IL-6, and upregulated Nos2 expression. Also, apoptotic (elevated caspase-3, Bax, and cytochrome-c with lowered Bcl-2) and necroptotic (elevated Pipk3 expression) changes were reported in damaged renal tissue. Co-treatment with Na2SeO3, LYC, or LYC-SeNPs restored the biochemical, molecular, and histological alterations in AKI. In comparison with Na2SeO3 or LYC treatment, LYC-SeNPs had the best nephroprotective profile. Conclusion Our findings authentically revealed that LYC-SeNPs co-administration could be a prospective candidate against AKI-mediated renal damage via antioxidant, anti-inflammatory, anti-apoptotic and anti-necroptotic activities.

Abstract
In this study, we evaluated the combined therapeutic efficacy of erythropoietin (a hematopoietic hormone produced by the fetal liver and kidney in response to inflammation and apoptosis) and sesame oil (from Sesamum indicum L.) on ischemic kidney injury following kidney transplantation in a rat model. Rats were assigned to the following groups: sham, control, 1000 U/kg erythropoietin, 1 mL/kg sesame oil, 1000 U/kg erythropoietin + 1 mL/kg sesame oil, and positive control. We measured the levels of blood urea nitrogen (BUN), creatinine, alanine aminotransferase (ALT), lipid peroxidation, reactive oxygen species (ROS), reduced glutathione (GSH), antioxidant enzymes, and proinflammatory markers and performed renal histopathological evaluation. The combined erythropoietin and sesame oil treatment significantly reduced BUN, ALT, creatinine, lipid peroxidation, ROS, and proinflammatory markers and GSH and antioxidant enzyme levels. Histopathological examination showed that the combined erythropoietin and sesame oil treatment significantly reduced necrosis. Therefore, combined treatment of sesame oil and erythropoietin may represent an effective therapeutic approach against ischemic kidney injury after kidney transplantation.

Abstract
AIM To compare and evaluate the hepatoprotective effect of liver parenchyma injection of ADSCs and portal vein injection of HRS in laparoscopic hepatic ischemia reperfusion combined with hepatectomy injury in miniature pigs. METHODS Eighteen miniature pigs were randomly assigned to IRI group, HRS group and ADSCs group. HRS was injected through the portal vein 10 min before reperfusion, 1 d, 2 d, and 3 d after surgery. ADSCs were injected into liver parenchyma after hepatectomy. The serum and liver tissue samples were collected at different time points (preoperative, and postoperative at 1 d, 3 d and 7 d). RESULTS Compared with the IRI group, both ADSCs and HRS groups can promote liver function recovery, reduce oxidative stress, reduce inflammation, and promote liver regeneration. Compared with HRS, ALT and TBIL in ADSCs group were significantly decreased at 3 d, and AST was significantly reduced at 1 d. The activities of SOD and GSH-Px in ADSCs group were significantly higher than that in HRS group, but the MDA level in HRS group was markedly lower than that in ADSCs group at 1 d. IL-1β was significantly lower in the ADSCs group than in the HRS group at 1 day after operation. The expressions of HGF and PCNA were significantly higher than that in the HRS group at 3 day after surgery. CONCLUSION Our study has demonstrated that HRS and ADSCs have significant hepatoprotective effects in miniature pigs after HIRI and hepatectomy injury. However, liver parenchyma injection of ADSCs is more beneficial to the recovery of liver function than portal vein injection of HRS.

Abstract
Background/aim Since the nature of ischemia/reperfusion (IR)-induced tissue damage is multifactorial and complex, in the current study, the effects of multiple treatment strategies via concomitant administration of erythropoietin (EPO) and N-acetylcysteine (NAC) with an ischemic preconditioning (IPC) regimen on renal IR injury were examined. Materials and methods Thirty male Wistar rats were subjected to bilateral occlusion of the renal pedicles for 50 min followed by reperfusion. EPO (1000 IU/kg) was administered for 3 days, as well as IPC before the IR and NAC (150 mg/kg) administration for 4 days after IR. The animals were randomly allocated into 6 groups (n = 5): sham, IR, EPO+IR, IPC+IR, NAC+IR, and EPO+IPC+NAC+IR. Kidney tissues and blood samples were obtained for oxidative stress, proinflammatory cytokines, and renal functional evaluations. Results IR caused significant inflammatory response, oxidative stress, and reduced renal function. Treatment with EPO, IPC, and NAC or a combination of two of them attenuated renal dysfunction and reduced the oxidative stress and inflammatory markers. Rats treated with the combination of EPO, IPC, and NAC showed a higher degree of protection compared to the other groups. Conclusion These results showed that concomitant administration of EPO and IPC along with posttreatment NAC may have additive beneficial effects on kidney IR injury during IR-induced acute renal failure.

Abstract
BACKGROUND Hydrogen-rich saline (HRS) has antioxidative, anti-inflammatory and anti-apoptotic properties. We investigated the effects of hydrogen on hepatic ischemia-reperfusion (I/R) and laparoscopic hepatectomy in swine. METHODS Twenty-one healthy Bama miniature pigs were randomly divided into the sham group, ischemia-reperfusion injury (IRI) group, HRS-5 (5 mL/kg) group, and HRS-10 (10 mL/kg) group. HRS was injected through the portal vein 10 min before reperfusion and at postoperative day 1, 2 and 3. The roles of HRS on oxidative stress, inflammatory response and liver regeneration were studied. RESULTS Compared with the IRI group, HRS treatment attenuated oxidative stress by increasing catalase activity and reducing myeloperoxidase. White blood cells in the HRS-10 group were reduced compared with the IRI group (P < 0.01). In the HRS-10 group, interleukin-1 beta, interleukin-6 and tumor necrosis factor alpha, C-reactive protein and cortisol were downregulated, whereas interleukin-10 was upregulated. In addition, HRS attenuated endothelial cell injury and promoted the secretion of angiogenic cytokines, including vascular endothelial growth factor, angiopoietin-1 and angiopoietin-2. HRS elevated the levels of hepatocyte growth factor, Cyclin D1, proliferating cell nuclear antigen, Ki-67 and reduced the secretion of transforming growth factor-beta. CONCLUSIONS HRS treatment may exert a protective effect against I/R and hepatectomy-induced hepatic damage by reducing oxidative stress, suppressing the inflammatory response and promoting liver regeneration.

Abstract
Acute kidney injury (AKI) and chronic kidney disease (CKD) are major concerns in worldwide public health, and their pathophysiology involves immune cells activation, being macrophages one of the main players of both processes. It is suggested that metabolic pathways could contribute to macrophage modulation and phosphatidylinositol‑3 kinase (PI3K) pathway was shown to be activated in kidneys subjected to ischemia and reperfusion as well as unilateral ureteral obstruction (UUO). Although PI3K inhibition is mostly associated with anti-inflammatory response, its use in kidney injuries has been shown controversial results, which indicates the need for further studies. Our aim was to unveil the role of PI3Kγ in macrophage polarization and in kidney diseases development. We analyzed bone-marrow macrophages polarization from wild-type (WT) and PI3Kγ knockout (PI3K KO) animals. We observed increased expression of M1 (CD86, CCR7, iNOS, TNF, CXCL9, CXCL10, IL-12 and IL-23) and decreased of M2 (CD206, Arg-1, FIZZ1 and YM1) markers in the lack of PI3Kγ. And this modulation was accompanied by higher levels of inflammatory cytokines in PI3K KO M1 cells. PI3K KO mice had increased M1 in steady state kidneys, and no protection was observed in these mice after acute and chronic kidney insults. On the contrary, they presented higher levels of protein-to-creatinine ratio and Kim-1 expression and increased tubular injury. In conclusion, our findings demonstrated that the lack of PI3Kγ favors M1 macrophages polarization providing an inflammatory-prone environment, which does not prevent kidney diseases progression.

Renoprotective effect of erythropoietin via modulation of the STAT6/MAPK/NF-κB pathway in ischemia/reperfusion injury after renal transplantation. Int J Mol Med 2017; 41:25-32.

Abstract
Ischemia/reperfusion injury (IRI) commonly occurs in renal transplantation. Erythropoietin (EPO) exerts a protective effect in IRI. To investigate the underlying molecular mechanism, rat models of renal IRI were established and treated with EPO and/or lentivirus-mediated EPO-siRNA, the signal transducer and activator of transcription 6 (STAT6) inhibitor AS1517499, the JNK inhibitor SP600125, the p38 mitogen-activated protein kinase (MAPK) inhibitor SB203580, and the nuclear factor (NF)-κB inhibitor lactacystin. Histological examination revealed that EPO protected the kidney from IRI, through decreasing the extent of tissue congestion and inflammatory cell infiltration; however, EPO siRNA did not exert the same protective effect. In addition, the EPO level was inversely associated with renal IRI. EPO downregulated the expression of interferon-γ, interleukin (IL)-4, creatinine and caspase-3, and upregulated the expression of IL-10, thymic stromal lymphopoietin, STAT6, p-JNK and p-p38, while the opposite effects were observed with the administration of EPO-siRNA and the specific respective inhibitors. Further results revealed that MAPK (p-JNK and p-p38) acted upstream of NF-κB, and that NF-κB signaling regulated the expression of caspase-1 and -3, which may be responsible for the cytotoxicity associated with IRI. Taken together, the results of the present study demonstrated that EPO exerted a protective effect in renal IRI via the STAT6/MAPK/NF-κB pathway. This protective effect of EPO may improve reperfusion tolerance in ischemic kidneys and benefit transplant recipients.

Abstract
Acute kidney injury (AKI) is a common disease with a complex pathophysiology. The old paradigm of identifying renal injury based on location-prerenal, intrarenal, and postrenal-is now being supplanted with a new paradigm based on observable kidney injury patterns. The pathophysiology of AKI on a molecular and microanatomical level includes inflammation, immune dysregulation, oxidative injury, and impaired microcirculation. Treatment has traditionally been supportive, including the avoidance of nephrotoxins, judicious volume and blood pressure management, hemodynamic monitoring, and renal replacement therapy. Fluid overload and chloride-rich fluids are now implicated in the development of AKI, and resuscitation with a balanced, buffered solution at a conservative rate will mitigate risk. Novel therapies, which address specific observable kidney injury patterns include direct oxygen-free radical scavengers such as α-lipoic acid, curcumin, sodium-2-mercaptoethane sulphonate, propofol, and selenium. In addition, angiotensin II and adenosine receptor antagonists hope to ameliorate kidney injury via manipulation of renal hemodynamics and tubulo-glomerular feedback. Alkaline phosphatase, sphingosine 1 phosphate analogues, and dipeptidylpeptidase-4 inhibitors counteract kidney injury via manipulation of inflammatory pathways. Finally, genetic modifiers such as 5INP may mitigate AKI via transcriptive processes.

Abstract
PURPOSE The aim of this study was to explore the cardioprotective effect of vitexin on chronic myocardial ischemia/reperfusion injury in rats and potential mechanisms. METHODS A chronic myocardial ischemia/reperfusion injury model was established by ligating left anterior descending coronary for 60 minutes, and followed by reperfusion for 14 days. After 2 weeks ischemia/reperfusion, cardiac function was measured to assess myocardial injury. The level of ST segment was recorded in different periods by electrocardiograph. The change of left ventricular function and myocardial reaction degree of fibrosis of heart was investigated by hematoxylin and eosin (HE) staining and Sirius red staining. Endothelium-dependent relaxations due to acetylcholine were observed in isolated rat thoracic aortic ring preparation. The blood samples were collected to measure the levels of MDA, the activities of SOD and NADPH in serum. Epac1, Rap1, Bax and Bcl-2 were examined by using Western Blotting. RESULTS Vitexin exerted significant protective effect on chronic myocardial ischemia/reperfusion injury, improved obviously left ventricular diastolic function and reduced myocardial reactive fibrosis degree in rats of myocardial ischemia. Medium and high-dose vitexin groups presented a significant decrease in Bax, Epac1 and Rap1 production and increase in Bcl-2 compared to the I/R group. It may be related to preventing myocardial cells from apoptosis, improving myocardial diastolic function and inhibiting lipid peroxidation. CONCLUSIONS Vitexin is a cardioprotective herb, which may be a promising useful complementary and alternative medicine for patients with coronary heart disease.
