Abstract
Sepsis is the most common cause of death from infection in the world. Unfortunately, there is no specific treatment for patients with sepsis, and management relies on infection control and support of organ function. A better understanding of the underlying pathophysiology of this syndrome will help to develop innovative therapies. In this regard, it has been widely reported that endothelial cell activation and dysfunction are major contributors to the development of sepsis. This review aims to provide a comprehensive overview of emerging findings highlighting the prominent role of mitochondria in the endothelial response in in vitro experimental models of sepsis. Additionally, we discuss potential mitochondrial targets that have demonstrated protective effects in preclinical investigations against sepsis. These promising findings hold the potential to pave the way for future clinical trials in the field.

Abstract
OBJECTIVE To explore the modulating effect of endogenous sulfur dioxide (SO2) on the ba-lance of oxidation/reduction in the cecal-ligation-and-puncture-induced septic rat myocardium. METHODS Forty male Sprague Dawley rats were randomized into control group, SO2group, sepsis group and sepsis + SO2group. The levels of procalcitonin (PCT), creatine kinase isoenzyme (CK-MB), cardiac troponin Ⅰ (cTn Ⅰ) and fatty acid binding protein (FABP) in plasma in each group of the rats were measured; The level of hydrogen peroxide (H2O2), level of nitric oxide (NO), activity of myeloperoxidase (MPO), activity of hydroxyl free radical (·OH) and level of malondialdehyde (MDA) in myocardial tissue were measured; Total antioxidant capacity (T-AOC), activity of catalase (CAT), level of cytochrome oxidase (CO), level of glutathione (GSH), level of glutathione oxidase (GSH-px) and activity of superoxide dismutase (SOD) in myocardial tissue were measured. RESULTS The level of PCT in plasma in the rats with sepsis increased from (0.93±0.26) μg/L to (2.45±0.52) μg/L (P < 0.01), and decreased to (1.58±0.36) μg/L after the intervention of sulfur dioxide donor (P < 0.01). In sepsis, the plasma CK-MB, cTn Ⅰ and FABP levels in the rats increased respectively from (14.46±6.48) μg/L, (151.25±30.14) ng/L and (2.72±0.65) μg/L to (23.72±7.72) μg/L, (272.78±52.70) ng/L and (5.22±1.01) μg/L (P all < 0.01), and decreased to (16.74±3.63) μg/L, (184.86±37.72) μg/L and (3.31±0.84) μg/L (all P < 0.05) after the intervention of sulfur dioxide donor. The level of H2O2, level of NO, activity of MPO, activity of ·OH and level of MDA in myocardial tissue in the rats with sepsis increased respectively from (67.26±8.77) mmol/g, (38.39±6.93) μmol/g, (358.25±68.12) U/g, (648.42±93.69) U/ mg and (4.55±0.96) μmol/g to (111.45±17.35) mmol/g, (51.04±5.91) μmol/g, (465.88±76.76) U/g, (873.75±123.47) U/mg and (7.25±0.86) μmol/g (all P < 0.01), and decreased respectively to (75.99±10.52) mmol/g, (39.39±7.80) μmol/g, (393.17±51.5) U/g, (710.54±106.33) U/mg and (5.16±0.65) μmol/g after the intervention of the sulfur dioxide donor (all P < 0.05). The activity of T-AOC, activity of CAT, level of CO, level of GSH, level of GSH-px and activity of SOD in myocardial tissue in the rats with sepsis increased respectively from (2.07±0.37) U/mg, (169.25±36.86) U/g, (1.35±0.32) μmol/g, (103.51±16.62) μmol/g, (38.40±7.97) μmol/g and (38.50±8.30) U/mg to (1.42±0.39) U/mg, (98.44±26.56) U/g, (0.96±0.21) μmol/g, (68.05±7.35) μmol/ g, (23.83±5.04) μmol/g and (23.11±4.63) U/mg (P all < 0.01), and increased respectively to (1.83±0.37) U/mg, (146.14±31.63) U/g, (1.28±0.20) μmol/g, (92.10±11.84) μmol/g, (37.16±3.01) μmol/g and (37.29±2.62) U/mg (P all < 0.05) after the intervention of the sulfur dioxide donor. CONCLUSION Endogenous SO2 can protect rat myocardium in sepsis by modulating the ba-lance of oxidation and reduction.

Protective role of crocin against sepsis-induced injury in the liver, kidney and lungs via inhibition of p38 MAPK/NF-κB and Bax/Bcl-2 signalling pathways. PHARMACEUTICAL BIOLOGY 2022; 60:543-552. [PMID: 35225146 PMCID: PMC8890572 DOI: 10.1080/13880209.2022.2042328] [Citation(s) in RCA: 15] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/29/2021] [Revised: 12/28/2021] [Accepted: 02/09/2022] [Indexed: 06/01/2023]
Abstract
CONTEXT Crocin has been reported to have multiple bioactivities. However, the effect of crocin administration on caecal ligation and puncture (CLP)-induced sepsis remains unknown. OBJECTIVE We investigated the effects of crocin on CLP-induced sepsis in mice and the underlying mechanism of action. MATERIALS AND METHODS Five experimental groups (n = 10) of BALB/c mice were used: control, CLP (normal saline) and CLP + crocin (50, 100 and 250 mg/kg, 30 min prior to CLP). Mice were sacrificed 24 h after CLP. Liver, kidney and lung histopathology, indicator levels, apoptotic status, pro-inflammatory cytokines and relative protein levels were evaluated. RESULTS Compared to the CLP group, crocin treatment significantly increased the survival rate (70%, 80%, 90% vs. 30%). Crocin groups exhibited protection against liver, kidney and lung damage with mild-to-moderate morphological changes and lower indicator levels: liver (2.80 ± 0.45, 2.60 ± 0.55, 1.60 ± 0.55 vs. 5.60 ± 0.55), kidney (3.00 ± 0.71, 2.60 ± 0.55, 1.40 ± 0.55 vs. 6.20 ± 0.84) and lungs (8.00 ± 1.59, 6.80 ± 1.64, 2.80 ± 0.84 vs. 14.80 ± 1.79). The proinflammatory cytokines (IL-1β, TNF-α, IL-6 and IL-10 levels in the crocin groups) were distinctly lower and the apoptotic index showed a significant decrease. Crocin administration significantly suppressed p38 MAPK phosphorylation and inhibited NF-κB/IκBα and Bcl-2/Bax activation. DISCUSSION AND CONCLUSIONS Pre-treatment with crocin confers protective effects against CLP-induced liver, kidney and lung injury, implying it to be a potential therapeutic agent.

Abstract
Sepsis is a systemic inflammatory response syndrome caused by infection, following with acute injury to multiple organs. Sepsis-induced acute kidney injury (AKI) is currently recognized as one of the most severe complications related to sepsis. The pathophysiology of sepsis-AKI involves multiple cell types, including macrophages, vascular endothelial cells (ECs) and renal tubular epithelial cells (TECs), etc. More significantly, programmed cell death including apoptosis, necroptosis and pyroptosis could be triggered by sepsis in these types of cells, which enhances AKI progress. Moreover, the cross-talk and connections between these cells and cell death are critical for better understanding the pathophysiological basis of sepsis-AKI. Mitochondria dysfunction and oxidative stress are traditionally considered as the leading triggers of programmed cell death. Recent findings also highlight that autophagy, mitochondria quality control and epigenetic modification, which interact with programmed cell death, participate in the damage process in sepsis-AKI. The insightful understanding of the programmed cell death in sepsis-AKI could facilitate the development of effective treatment, as well as preventive methods.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2021; 81:153411. [PMID: 33310307 DOI: 10.1016/j.phymed.2020.153411] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/01/2020] [Revised: 11/06/2020] [Accepted: 11/14/2020] [Indexed: 06/12/2023]
Abstract
BACKGROUND Nodakenin, a coumarin glucoside isolated from the roots of Angelica biserrata, has been reported to have anti-inflammatory, antibacterial, anticancer effects. However, despite these studies, the potential liver protective effects of nodakenin in inflammatory liver injury models have not been reported. METHODS A mouse model of inflammatory liver injury was induced by injection of lipopolysaccharide (LPS) (15 mg/kg, intraperitoneally (i.p)). Liver tissue AST, ALT, ROS, T-GSH and T-SOD were analyzed by ELISA. The concentrations of TNF-α, IL-6, and IL-1β in serum of LPS-induced inflammatory liver injury mice were analyzed. The mRNA expression levels of GPx1, catalase, SOD1, SOD2, TNF-α, IL-6, IL-1β, iNOS and COX-2 were analyzed using real-time PCR. The expressions of MAPK, IRF3, NF-κB, Nrf2, HO-1, caspase-3 and caspase-7 were analyzed using western blotting. Liver tissue was stained with IHC to confirm NF-κB, Nrf-2, HO-1, caspase-3, Bax, and Bcl2. Tunnel analysis was performed to confirm the fragmented nuclear DNA characteristics of apoptosis. RESULTS The administration of nodakenin (10 and 30 mg/kg) reduced serum aminotransferase levels compared to LPS-induced liver damage and significantly improved the oxidative state of liver tissue and pathological damage. Moreover, inhibited the phosphorylation of transforming growth factor beta (TGF-β)-activated kinase (TAK)-1 in LPS-induced inflammatory liver injury model, and significantly inhibited the transcriptional of nuclear factor-kappa B (NF-kB) and the secretion of pro-inflammatory mediators. In addition nodakenin pre-treatment also attenuated hepatocyte death by regulating apoptosis-related mitochondrial proteins, such as cysteinyl aspartate specific proteinase 3 (caspase 3), poly (ADP-ribose) polymerase (PARP), B-cell lymphoma 2 (Bcl-2) and Bcl-2-associated X (Bax). CONCLUSION Our findings suggest that nodakenin has anti-inflammatory, anti-oxidant and anti-apoptotic activity and may be an adjunctive prevention agent for liver injury.

Abstract
Oxidative stress of endothelial cells is thought to be a principal cause that induces many cardiovascular diseases. Hydroxysafflor yellow A (HSYA) is a major active component in traditional Chinese medicine safflower and has been used to cure ischemic cardiovascular diseases in China for many years. This study aims to investigate whether HSYA has a repairing effect on oxidative damage of human umbilical vein endothelial cells (HUVECs) induced by H2O2 and to provide a theoretical basis for the clinical treatment of cardiovascular diseases related to traditional Chinese medicine. Based on the establishment of an H2O2-induced HUVEC oxidative injury model, the cell viability and proliferation rate were measured by the MTT assay and EdU staining. The intracellular GSH/GSSG ratio and SOD activity were determined by kits. The ROS level was detected by flow cytometry. And the BAX, Bcl-2, PTEN, and AKT expressions were evaluated with western blotting methods. The results showed that HSYA treatment significantly attenuated the H2O2-induced HUVEC cell damage, increased the intracellular GSH/GSSG ratio and unit SOD activity also, and decreased the intracellular ROS levels. Furthermore, HSYA increased the expressions of AKT and Bcl-2 proteins and inhibited the expressions of BAX and PTEN proteins. These suggest that HSYA exerts repair effects on H2O2-induced oxidative damage in HUVECs, and the mechanisms may be related to the influence of BAX/Bcl-2 expression and AKT/PTEN signal pathway expression.

Abstract
Sepsis is an acute systemic inflammatory response of the body to microbial infection and a life-threatening condition associated with multiple organ failure. Recent data suggest that sepsis survivors present with long-term myopathy due to the dysfunction of skeletal muscle stem cells and satellite cells. Accumulating studies have implicated chitinase-3-like-1 protein (CHI3L1) in a variety of infectious diseases, specifically sepsis. Therefore, the aim of the present study is to elucidate the potential mechanism by which CHI3L1 is involved in the injury of skeletal muscle stem cells in mouse models of sepsis. An in vitro cell model was developed by lipopolysaccharide (LPS) and in vivo mouse model of sepsis was induced by CRP-like protein (CLP). To elucidate the biological significance behind the silencing of CHI3L1, modeled skeletal muscle stem cells and mice were treated with siRNA against CHI3L1 or overexpressed CHI3L1. Highly expressed CHI3L1 was found in skeletal muscle tissues of mice with sepsis. Besides, siRNA-mediated silencing of CHI3L1 was revealed to increase Bcl-2 expression along with cell proliferation, while diminishing Bax expression, cell apopstosis as well as serum levels of TNF-α, IL-1β, INF-γ, IL-10, and IL-6. Taken conjointly, this present study provided evidence suggesting that downregulation of CHI3L1 has the potential to prevent the injury of skeletal muscle stem cells in mice with sepsis. Collectively, CHI3L1 may serve as a valuable therapeutic strategy in alleviating sepsis.

Abstract
Gastric ulcer is a common problem affecting the gastrointestinal tract. Spirulina and wheatgrass are natural substances that have anti-inflammatory and antioxidant effects. The aim of the Work was to elucidate the possible protective role of spirulina and wheatgrass versus standard treatment esomeprazole on indomethacin-induced gastric ulcer in adult male albino rats. Eighty adult male albino rats were divided into eight groups: group I (the control group), group II that received indomethacin (100 mg/kg orally), group III that received esomeprazole (20 mg/kg orally), group IV that received spirulina (1000 mg/kg orally), group V that received wheatgrass (1000 mg/kg orally), group VI that received indomethacin (100 mg/kg) + esomeprazole (20 mg/kg), group VII that received indomethacin (100 mg/kg) + spirulina (1000 mg/kg) and group VIII that received indomethacin (100 mg/kg) + wheatgrass (1000 mg/kg). Six hours after indomethacin treatment, all rats were anesthetized and their stomachs obtained for measures of gastric acidity, pepsin activity, mucin content, gastrin, ulcer index, total antioxidant capacity (TAC), tumor necrosis factor -α (TNF-α), interleukin-8 (IL8), proapoptotic protein (Bax). Histological (using H&E stain, PAS reaction) and immunohistochemical (using anti Ki67 immunostain) techniques were performed. Western immunoblot analysis for heat shock protein 70 (HSP70) was also done. Moreover, a morphometric study was done for area% of positive immunoreactive cells for Ki67 and optical density and area% of PAS reaction. All performed measurements were followed by statistical analysis. Indomethacin induced loss of normal architecture of gastric mucosa with sloughing of surface epithelium and inflammatory cellular infiltration. It also led to a significant increase in gastric acidity, inflammatory mediators (TNF-α, IL-8), pro-apoptotic protein Bax and a significant decrease in TAC levels and HSP-70 expression. There was also a significant decrease in area% of Ki67 immunoreactivity and area% and optical density of PAS reaction as compared with the control group and other pre-treated rats. These disturbed parameters were associated with increased ulcer index. In pre-treatment groups, the structure of the mucosa was similar to control with marked improvement in the biochemical assay. In conclusion, Spirulina and wheatgrass can partly protect the gastric mucosa against indomethacin-induced damage to a degree similar to that of the classical treatment esomeprazole.

J Cell Physiol 2019; 234:17839-17853. [PMID: 30972748 DOI: 10.1002/jcp.28410] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2018] [Revised: 01/22/2019] [Accepted: 01/24/2019] [Indexed: 12/15/2022]
Abstract
Sepsis is a systemic inflammatory response that may be induced by trauma, infection, surgery, and burns. With the aim of discovering novel treatment targets for sepsis, this current study was conducted to investigate the effect and potential mechanism by which microRNA-30a (miR-30a) controls sepsis-induced liver cell proliferation and apoptosis. Rat models of sepsis were established by applying the cecal ligation and puncture (CLP) method to simulate sepsis models. The binding site between miR-30a and suppressor of cytokine signaling protein 1 (SOCS-1) was determined by dual luciferase reporter gene assay. The gain-of-and-loss-of-function experiments were applied to analyze the effects of miR-30a and SOCS-1 on liver cell proliferation and apoptosis of the established sepsis rat models. The expression of miR-30a, SOCS-1, Janus kinase 2 (JAK2), signal transducer and activator of transcription 3 (STAT3), Bcl-2 associated X protein (Bax), B cell lymphoma-2 (Bcl-2), toll-like receptor 4 (TLR4), and high-mobility group box 1 (HMGB1), and the extent of JAK2 and STAT3 phosphorylation were all determined. Sepsis led to an elevation of miR-30a and also a decline of SOCS-1 in the liver cells. SOCS-1 was negatively regulated by miR-30a. Upregulated miR-30a and downregulated SOCS-1 increased the expression of JAK2, STAT3, Bax, TLR4, and HMGB1 as well as the extent of JAK2 and STAT3 phosphorylation whereas impeding the expression of SOCS-1 and Bcl-2. More important, either miR-30a elevation or SOCS-1 silencing suppressed liver cell proliferation and also promoted apoptosis. On the contrary, the inhibition of miR-30a exhibited the opposite effects. Altogether, we come to the conclusion that miR-30a inhibited the liver cell proliferation and promoted cell apoptosis by targeting and negatively regulating SOCS-1 via the JAK/STAT signaling pathway in rats with sepsis.

Abstract
The aim of this study, was to determine the effect of sulfasalazine for different periods
of time reduces disseminated intravascular coagulation, inflammation and organ damages by
inhibiting the nuclear factor kappa beta pathway. The study was performed with 30 Wistar
albino rats and the groups were established as Control group, LPS group; endotoxemia was
induced with LPS, SL5 group: sulfasalazine (300 mg/kg, single dose daily) was administered
for 5 days before the LPS-induced endotoxemia, and LS group: sulfasalazine (300 mg/kg,
single dose) was administered similtenously with LPS. Hemogram, biochemical, cytokine
(IL-1β, IL-6, IL-10, TNF-α) and acute phase proteins (HPT, SAA, PGE2) analyzes and
oxidative status values were measured from blood samples at 3 and 6 h after the last
applications in the all groups. The rats were euthanized at 6 h and mRNA
levels of BCL2 and BAX genes were examined from liver
and brain tissues. Sulfasalazine reduced the increased IL-1β, IL-6, TNF-α and
PGE2 levels and significantly increased anti-inflammatory cytokine IL-10
levels. In addition, decreasing of ATIII level was prevented in the SL5 group, and
decreasing of fibrinogen levels were prevented in the LS and SL5 groups within first 3 h.
In LPS group, leukocyte and thrombocyte levels were decreased, however sulfasalazine
application inhibited decreases of leukocyte levels in LS and SL5 groups. In addition,
sulfasalazine inhibited the decrease of total antioxidant capacity and unchanged apoptosis
in brain and liver. In conclusion, the use of sulfasalazine in different durations reduce
the excessive inflammation of endotoxemia cases.

Abstract
This study is aimed to investigate whether simvastatin induces cardiomyocytes survival signaling in endotoxin (lipopolysaccharide, LSP)-induced myocardial injury, and if so, further to determine a role of survivin in simvastatin-anti-apoptotic effect. Wistar rats were pretreated with simvastatin (10–40 mg/kg po) before a single non-lethal dose of LPS. In myocardial tissue, LPS induced structural disorganization of myofibrils with significant inflammatory infiltrate (cardiac damage score, CDS = 3.87 ± 0.51, p < 0.05), whereas simvastatin dose-dependently abolished structural changes induced by LPS (p < 0.01). Simvastatin in 20 mg/kg and 40 mg/kg pretreatment, dose dependently, attenuated myocardial apoptosis determined as apoptotic index (28.8 ± 4.5% and 18.9 ± 3.5, p < 0.05), decreased cleaved caspase-3 expression (32.1 ± 5.8%, p < 0.01), along with significant Bcl-xL expression in the simvastatin groups (p < 0.01). Interestingly, in the simvastatin groups were determined significantly increased expression of survivin (p < 0.01), but in negative correlation with cleaved caspase-3 and apoptotic indices (p < 0.01). Simvastatin has a cardioprotective effects against LPS induced apoptosis. The effect may be mediated by up-regulation of survivin via activation of NF-κB, which leads to reduced activation of caspase-3 and consequent apoptosis of cardiomyocytes in experimental sepsis.

Abstract
Background: Oxidized low-density lipoprotein (ox-LDL)-induced oxidative stress and endothelial apoptosis are essential for atherosclerosis. Our previous study has shown that ox-LDL-induced apoptosis is mediated by the protein kinase RNA-like endoplasmic reticulum kinase (PERK)/eukaryotic translation initiation factor 2α-subunit (eIF2α)/CCAAT/enhancer-binding protein homologous protein (CHOP) endoplasmic reticulum (ER) stress pathway in endothelial cells. Statins are cholesterol-lowering drugs that exert pleiotropic effects including suppression of oxidative stress. This study aimed to explore the roles of simvastatin on ox-LDL-induced ER stress and apoptosis in endothelial cells. Methods: Human umbilical vein endothelial cells (HUVECs) were treated with simvastatin (0.1, 0.5, or 2.5 μmol/L) or DEVD-CHO (selective inhibitor of caspase-3, 100 μmol/L) for 1 h before the addition of ox-LDL (100 μg/ml) and then incubated for 24 h, and untreated cells were used as a control group. Apoptosis, expression of PERK, phosphorylation of eIF2α, CHOP mRNA level, and caspase-3 activity were measured. Comparisons among multiple groups were performed with one-way analysis of variance (ANOVA) followed by post hoc pairwise comparisons using Tukey's tests. A value of P < 0.05 was considered statistically significant. Results: Exposure of HUVECs to ox-LDL resulted in a significant increase in apoptosis (31.9% vs. 4.9%, P < 0.05). Simvastatin (0.1, 0.5, and 2.5 μmol/L) led to a suppression of ox-LDL-induced apoptosis (28.0%, 24.7%, and 13.8%, F = 15.039, all P < 0.05, compared with control group). Ox-LDL significantly increased the expression of PERK (499.5%, P < 0.05) and phosphorylation of eIF2α (451.6%, P < 0.05), if both of which in the control groups were considered as 100%. Simvastatin treatment (0.1, 0.5, and 2.5 μmol/L) blunted ox-LDL-induced expression of PERK (407.8%, 339.1%, and 187.5%, F = 10.121, all P < 0.05, compared with control group) and phosphorylation of eIF2α (407.8%, 339.1%, 187.5%, F = 11.430, all P < 0.05, compared with control group). In contrast, DEVD-CHO treatment had no significant effect on ox-LDL-induced expression of PERK (486.4%) and phosphorylation of eIF2α (418.8%). Exposure of HUVECs to ox-LDL also markedly induced caspase-3 activity together with increased CHOP mRNA level; these effects were inhibited by simvastatin treatment. Conclusions: This study suggested that simvastatin could inhibit ox-LDL-induced ER stress and apoptosis in vascular endothelial cells.

Effect of Xuefu Zhuyu Decoction Pretreatment on Myocardium in Sepsis Rats. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2018; 2018:2939307.

Abstract
Xuefu Zhuyu Decoction (XFZYD), the classical recipe for promoting blood circulation by removing blood stasis, has been used in China for a long history clinically. XFZYD has been found to improve cardiac function through reducing inflammation. However, the effect of XFZYD on myocardial apoptosis remains unclear. Herein, we investigated the mechanism of XFZYD preconditioning on myocardial injury in sepsis rats. The rats were treated with XFZYD one week, followed with intraperitoneal injection of lipopolysaccharide (LPS: 10 mg/kg) to induce sepsis. Pretreatment with XFZYD could reverse the effects of LPS-induced decreased mean arterial pressure (MAP) and increased heart rate (HR). XFZYD decreased the levels of malondialdehyde (MDA), superoxide dismutase (SOD), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) in serum or in heart. TUNEL staining revealed that the apoptotic index of XFZYD was significantly lower compared with the LPS group (P<0.05). Western blot results showed that the high doses of pretreatment XFZYD group can reduce the Bax expression of myocardial tissue in rats (P<0.05, P<0.01). The expression of Bcl-2 in XFZYD group was significantly higher than that in the LPS group (P<0.01), while the expression of caspase-3 in treatment group was significantly lower than that in the LPS group only after 12 h modeling (P<0.01). In addition, caspase-3 activity in rat cardiomyocytes of XFZYD-treated animals was significantly decreased. These findings suggest that pretreatment with XFZYD exerts a protective effect in the myocardium of septic rats by inhibiting myocardial cell apoptosis and antioxidation.

Abstract
The aim of the present study was to examine the combined efficacy of simvastatin and kallistatin treatment for pediatric burn sepsis. A total of 72 pediatric patients with burn sepsis were recruited and randomly divided into 3 groups, receiving simvastatin (40 mg/day), kallistatin (20 mg/day) or combined treatment. ELISA, reverse transcription-quantitative polymerase chain reaction, western blotting and flow cytometry were used to analyze the therapeutic effects of simvastatin and kallistatin. The results revealed that combined treatment in pediatric burn sepsis patients decreased the inflammatory cytokine tumor necrosis factor α and interleukin (IL)-1β serum levels, whereas it increased IL-10 and human leukocyte antigen-D related levels. In addition, administration of combined simvastatin and kallistatin decreased the blood urea nitrogen and serum creatinine levels in the patients. It was also demonstrated that Toll-like receptor 4 expression on the surface of monocytes was markedly decreased, while suppressor of cytokine signaling-3 expression was increased in the combined treatment group as compared with the kallistatin or simvastatin treatment alone. Combined treatment also promoted human endothelial cell (HEC) growth compared with the single treatment groups and inhibited the high mobility group box-1 (HMGB1) levels, HMGB1-induced nuclear factor-κB activation and inflammatory gene expression levels in these cells. The study further demonstrated that combined treatment significantly decreased HEC apoptosis through the upregulation of B-cell lymphoma 2 (Bcl-2) and P53 expression levels, as well as downregulation of Bcl-2-associated X protein and caspase-3 levels. In conclusion, these observations indicated that combined treatment with simvastatin and kallistatin inhibited HEC apoptosis, which may be a potential therapeutic strategy for the treatment of pediatric burn sepsis patients.

Abstract
Polysaccharide extracted from the Maitake mushroom (MP) is considered as a potential anticancer agent. The present study was performed to investigate the cytotoxic effects of MP and vitamin C (VC) alone and in combination on the viability of human neuroglioma M059 K cells in vitro. A combination of MP (1.0 mg/mL) and VC (0.4 mmol/L) led to a 53.10% reduction in cell viability and this treatment induced cell cycle arrest at the G2/M phase, and apoptosis occurred in 38.54% of the cells. Results of Hoechst 33258 staining and Western blot showed apoptotic cells appeared and changes in the expression of apoptosis-related proteins (upregulation of Bax and caspase-3, downregulation of Bcl-2, and activation of poly-(ADP-ribose)-polymerase). Moreover, the activities of caspase-3, caspase-8, and caspase-9 were enhanced in M059 K cells. The inhibiting effect of combined treatment with MP and VC on M059 K cells indicates the mechanism of anticancer activity involved induction of cell apoptosis.

Abstract
BACKGROUND Esmolol is a highly selective beta 1 receptor blocker with various effects such as slowing heart rate, lowering blood pressure and reducing myocardial oxygen consumption. However, few studies have reported the use of beta blockers in sepsis with multiple organ dysfunctions. This study aimed to investigate the effects of esmolol on reducing apoptosis and inflammation in early sepsis rats with abdominal infection. METHODS Rats were randomly divided into sham operation group, sepsis group, antibiotic group, Esmolol + antibiotic group with low, median and high dose Esmolol (L group, M group and H group). Values between two or more groups were compared by independent t-tests. RESULTS In the liver and kidney, we found inflammatory infiltration in sepsis group while pathological aspects reduced in L, M and H groups. Bcl-2 mRNA and protein levels increased while Bax mRNA and protein levels decreased in the liver and kidney of L, M and H groups. Serum IL-6, HMGB-1 and TNF-α levels decreased but IL-10 level increased in L, M and H groups, compared to sepsis group. Compared to sepsis and antibiotic groups, the levels of myocardial enzymes were lower in L, M and H groups. CONCLUSION The administration of esmolol in early sepsis may reduce inflammation, inhibit apoptosis and protect key organs.

Abstract
Severe sepsis remains a worldwide threat, not only in industrialized countries, due to their aging population, but also in developing countries where there still are numerous cases of neonatal and puerperal sepsis. Tools for early diagnosis, a prerequisite for rapid and appropriate antibiotic therapy, are still required. In this review, we highlight some recent developments in our understanding of the associated systemic inflammatory response that help deciphering pathophysiology (e.g., epigenetic, miRNA, regulatory loops, compartmentalization, apoptosis and synergy) and discuss some of the consequences of sepsis (e.g., immune status, neurological and muscular alterations). We also emphasize the challenge to better define animal models and discuss past failures in clinical investigations in order to define new efficient therapies.

Zheng YJ, Xu WP, Ding G, Gao YH, Wang HR, Pan SM. Expression of HMGB1 in septic serum induces vascular endothelial hyperpermeability. Mol Med Rep 2015; 13:513-21. [PMID: 26572550 DOI: 10.3892/mmr.2015.4536] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2014] [Accepted: 09/09/2015] [Indexed: 11/06/2022] Open
Abstract
The aim of the present study was to investigate the effects of high mobility group protein B1 (HMGB1), which is expressed in the serum of patients with sepsis, on vascular endothelial permeability. Sera from patients with sepsis were used to treat endothelial cells (ECs), and the effect on endothelial permeability was evaluated using immunofluorescence. The morphologies of endothelial cytoskeletal actin and vascular endothelial (VE)‑cadherin were assessed using laser scanning confocal microscopy. The protein expression levels of HMGB1, B‑cell lymphoma 2 (BCL‑2) and BCL‑2‑associated X protein (BAX) were detected using western blotting. EC apoptosis was measured using flow cytometry. The results demonstrated that HMGB1 was significantly expressed in the serum 24 h following the onset of sepsis, and the expression levels peaked at 48 h, which were sustained until 96 h post‑onset. Compared with the control group, treatment of the ECs with 20% septic serum in vitro significantly increased endothelial monolayer permeability (P<0.01), markedly induced transcellular filamentous (F)‑actin rearrangement with stress fiber formation, and resulted in the localization of VE‑cadherin fragmentations at the cell borders with increased gaps between ECs. Furthermore, flow cytometry showed that the apoptotic rate of ECs was significantly increased following treatment with septic serum. In addition, the expression levels of BAX were significantly increased, whereas the expression levels of BCL‑2 were significantly decreased. Pretreatment with an HMGBI inhibitor (ethyl pyruvate; 5 µM) 24 h prior to treatment with the septic serum attenuated the effects of septic serum treatment. Together, these findings suggested that treatment of ECs with sera from patients with sepsis may induce the loss of vascular endothelial monolayer integrity, elicit the formation of endothelial F‑actin stress fibers and initiate VE‑cadherin redistribution, which may be attributed to high levels of HMGB1 in the serum. This mechanism also appears to involve changes in the activation of BAX and BCL‑2, resulting in EC apoptosis.

Abstract
AIM: To evaluate human pancreatic carcinoma cell line (PANC-1) cells apoptosis and Bcl-2 and Bax expression induced by Yin Chen Hao Decoction (YCHD).
METHODS: The cell growth inhibitory rate was determined by MTT assay. Apoptosis of PANC-1 cells before and after treatment with YCHD was determined by TUNEL staining. Expression of the apoptosis-associated genes, Bcl-2 and Bax, was detected by immunohistochemical staining and reverse transcription -PCR.
RESULTS: YCHD inhibited the growth of PANC-1 cells. Following treatment with YCHD for 24-96 h, the apoptotic rate of PANC-1 cells increased with time. In addition, the positive rate of Bcl-2 protein expression decreased in a time-dependent manner, whereas the positive rate of Bax protein expression increased in a time-dependent manner. Following treatment of with YCHD for 24-96h, expression of BAX mRNA increased gradually and BCL-2 mRNA reduced gradually with time.
CONCLUSION: YCHD induces apoptosis of PANC-1 cells mediated in part via up-regulation of BAX and down-regulation of BCL-2.
