Radical Scavenging Ability

A hepatoprotective medicine, Yang-Gan-Wan (YGW), was used to treat hepatic damage in cell and mouse models. We performed a 1,1-diphenyl-2- picrylhydrazyl (DPPH) assay and found that YGW exhibited a significantly high free radical scavenging ability. Furthermore, the results of the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay revealed that YGW treatment could alleviate lipopolysaccharide (LPS)-induced damage in Kupffer cells (liver macrophages). Enzyme-linked immunosorbent assay results demonstrated that YGW treatment could alleviate LPS-induced inflammation in Kupffer cells by inhibiting the expression of tumor necrosis factor (TNF)-α and interleukin (IL)-1β. By quantifying the serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), we found that YGW treatment could alleviate hepatic damage and improve immunity in acetaminophen- (APAP-) treated mice by inhibiting the expression of ALT and AST. The findings of hematoxylin and eosin and Masson’s trichrome staining indicated that YGW treatment could alleviate hepatic damage and reduce collagen fiber formation in the liver tissue of APAP-treated mice. Furthermore, immunohistochemistry staining and Western blot results showed that YGW treatment could alleviate oxidative stress, inflammation, and apoptosis in the liver tissue of APAP-treated mice by enhancing superoxide dismutase 2 (SOD2) expression but inhibiting TNF-α and caspase 3 expression. Our results suggest that YGW treatment exerted hepatoprotective effects on LPS-treated Kupffer cells and APAP-treated mice by inhibiting oxidation, inflammation, and apoptosis.

Abstract Coronary Artery Disease (CAD) is a chronic inflammatory disease caused by atherosclerosis and arteries become clogged due to plaque formation, fat accumulation, and various sorts of immune cells. IL-32 is a new proinflammatory cytokine, which enhances inflammation through inducing different inflammatory cytokines. The purpose of current research was to assess IL-32 serum levels in coronary artery disease subjects and its relationship with serum levels of IL-6 and TNF-α. Forty-two subjects diagnosed with CAD and thirty-nine control subjects were enrolled in the research. Serum levels of IL-6, TNF-α, and IL-32 were measured using the enzyme-linked immunosorbent assay (ELISA). IL-32, TNF-α, and IL-6 serum levels were significantly higher by 2.7, 3.48, and 3.2-fold in the CAD subjects than in control subjects, respectively. Moreover, no significant difference was found in TNF-α, IL-6 and IL-32 serum levels with the clogged arteries number in the CAD group. TNF-α and IL-32 serum levels in the CAD subjects with cardiac arterial stenosis in one major vessel were significantly increased than CAD subjects with cardiac arterial stenosis in more than one major vessels. ROC curve analysis revealed that serum levels of IL-32, TNF-α, and IL-6 showed good abilities in predicting CAD. Also, Multiple logistic regression analyses suggested that TNF-α, IL-6, and IL-32, serum levels of LDL and ox-LDL were independently related to the presence of CAD, while HDL serum levels were not. TNF-α, IL-32, and IL-6 showed an increase in CAD group and serum levels of these cytokines showed good abilities in predicting CAD. Our data suggested the involvement of TNF-α and IL-32 in the early stage of CAD.

Background: In traditional Chinese medicine, the Shugan-Jianpi recipe is often used in the treatment of nonalcoholic fatty liver disease (NAFLD). This study aimed to explore the mechanism of the Shugan-Jianpi recipe in relation to rats with NAFLD induced by a high-fat diet. Methods: Rats were randomly divided into eight groups: normal group (NG), model group (MG), low-dose Chaihu–Shugan–San group (L-CG), high-dose Chaihu–Shugan–San group (H-CG), low-dose Shenling–Baizhu–San group (L-SG), high-dose Shenling–Baizhu–San group (H-SG), low dose of integrated-recipes group (L-IG), and high dose of integrated-recipes group (H-IG). After 26 weeks, a lipid profile, aspartate, and alanine aminotransferases in serum were detected. The serum levels of inflammatory factors including interleukin (IL)-1β, IL-6, and tumor necrosis factor-alpha (TNF-α) were analyzed using the enzyme linked immunosorbent assay (ELISA) method. Hepatic pathological changes were observed with hematoxylin-eosin (HE) and oil red O staining. The expression of the p38 mitogen-activated protein kinases (MAPK)/nuclear factor-κB (NF-κB) pathway was detected by quantitative real-time PCR and Western blotting. Results: A pathological section revealed that NAFLD rats have been successfully reproduced. Compared with the model group, each treatment group had different degrees of improvement. The Shugan-Jianpi recipe can inhibit the serum levels of IL-1β, IL-6, and TNF-α in NAFLD rats. The expression of mRNA and a protein related to the p38 MAPK/NF-κB signaling pathway were markedly decreased as a result of the Shugan-Jianpi recipe. Conclusions: The Shugan-Jianpi recipe could attenuate NAFLD progression, and its mechanism may be related to the suppression of the p38 MAPK/NF-κB signaling pathway in hepatocytes.

Abstract Background Angiography is a safe cardiovascular technique for the diagnosis and treatment of the cardiovascular disorders. The potential effects of angiography on the cytokines are yet to be clarified completely. Interleukin-8 (IL-8) and tumor necrosis factor-alpha (TNF-α) are the important pro-inflammatory cytokines that participate in the pathogenesis of artery stenosis. The aim of his project was to study the angiography effects on the serum levels of IL-8 and TNF-α. Methods Fifty-five participants in three groups, without, with one and with more than one artery stenosis, were explored in this project. Serum levels of IL-8 and TNF-α were measured in the participants before and after angiography using enzyme linked immunosorbent assay (ELISA) technique. Results Serum levels of IL-8, but not TNF-α, were significantly decreased following angiography. X-ray doses had moderate positive correlation with serum levels of TNF-α in the patients with more than one artery stenosis. Serum levels of IL-8 and TNF-α were not different among male and female participants in all groups. Discussion Angiography may be a protective factor for inflammation in IL-8 dependent manner. Using angiography in the patients with more than one artery stenosis needs to be executed cautiously.

Objective: The purpose of this study was to explore the application of dexmedetomidine (Dex) in cardiopulmonary bypass. Methods: A total of 60 patients undergoing elective cardiopulmonary bypass were divided into control (C) group and Dex group. In the Dex group, appropriate amount of Dex was added into the membrane lung prefilling solution before anesthesia induction, while those in control group were given normal saline. The levels of mean arterial pressure (MAP) and heart rate (HR) at different times were measured. The levels of cardiac troponin I (CTNI), malondialdehyde (MDA), interleukin 6 (IL-6), and tumor necrosis factor α (TNF-α) at different points (T0/T1/T2/T3/T4) in both groups were measured by enzyme-linked immunosorbent assay kits. Results: The intraoperative and postoperative levels of MAP and HR in the 2 groups were significantly lower than those preoperatively ( P < .05). The levels of MAP and HR in the Dex group were significantly lower than those of the C group ( P < .05). The levels of CTNI/MDA/IL-6/TNF-α at different points in both groups were significantly higher than those at T0 ( P < .05). The serum levels of CTNI, MDA, IL-6, and TNF-α in the Dex group at T1/T2/T3/T4 were significantly lower than those in the C group ( P < .05). The rate of arrhythmia in the Dex group was significantly lower than that in the C group ( P < .05). Conclusion: Dexmedetomidine has a stable effect in cardiopulmonary priming solution.

Abstract Abstract 4484 Introduction Several studies have demonstrated, that TNF α and its receptors (sTNFR) can be used as prognostic markers for major transplant related complications (TRC) after allogeneic haematopoietic stem cell transplantation (alloHSCT). Measurement of that inflammatory cytokine and sTNFR during pretransplant conditioning and early after transplantation may also reflect the conditioning-induced tissue damage. Patients and methods Our study included a group of 36 adult patients with acute myeloid leukemia (AML) in complete remission, who underwent alloHSCT following standard myeloablative conditioning according to Bu/Cy protocol (17 patients) or reduced-toxicity myeloablative conditioning with treosulfan-based regimens (19 patients). 21 patients received alloHSCT from a sibling and 15 from an unrelated donor. The expression of TNF-α, TNFRI and TNFRII were analyzed using reverse transcription-polymerase chain reaction (RT-PCR) in peripheral blood mononuclear cells (PBMC) before the start of conditioning, on the day of transplantation and on day 30 after alloHSCT. We examined β-actin as well, which constitutes an endogenous amplification control and is a housekeeping gene. sTNFRI and sTNFRII serum levels were measured using an enzyme-linked immunosorbent assay (ELISA) at the same defined time points before and after alloHSCT. The Mann-Whitney U test was used to evaluate the significance of differences between the analyzed groups and the Shapiro-Wilk and Lilliefords tests to estimate data distribution. Results TNFRII mRNA was not detected in PBMC, but TNF-α and TNFRI mRNA as well as β-actin were discovered. The real time PCR showed significant decrease (p<0.004) in TNFRI expression on day 30 after transplantation in comparison to day 0. On day 30 expression of TNFRI was higher in patients treated with Treosulfan-based regimens than in patients treated with Bu/Cy (p=0.027). Plasma levels of sTNFRI and sTNFRII observed on day 0 and 30 were significantly elevated (p<0.05) compared with the levels prior to conditioning. Conclusion Our data indicate that sTNFRI and sTNFRII can be investigated as the markers reflecting the toxicity of the conditioning regimens in AML patients undergoing alloHSCT. The associations between TNF-α, TNFRI expression, serum levels of sTNFR and the clinical outcome after alloHSCT should be evaluated. Disclosures: No relevant conflicts of interest to declare.

Diosmetin (DGVL) extracted from the traditional Chinese herb Galium verum L. has been found to have anticancer activity. In this study, the effects of DGVL on the thymus of U14-bearing mice were investigated. Using flow cytometry, peripheral blood lymphocytes were characterized based on the expression of surface markers for T helper cells (CD4+) and T suppressor cells (CD8+). Serum levels of tumor necrosis factor α (TNF-α), interleukin-2 (IL-2), IL-10, and transforming growth factor β1 (TGF-β1) and a cell proliferation assay were determined with an enzyme-linked immunosorbent assay. The expression of Fas and Fas ligand (FasL) on the thymus was determined by Western blotting. Our results showed that DGVL inhibited tumor growth and significantly increased the thymus weight compared with the control. Also, DGVL elevated serum levels of IL-2 and significantly reduced levels of TNF-α, TGF-β1, and IL-10 in a dose-dependent manner. Histological study and terminal dUTP nick end labeling staining results showed that DGVL protected thymus tissue against the onslaught of tumor growth by inhibiting thymus lymphocyte apoptosis. The cell proliferation assay revealed that DGVL might promote more thymus lymphocytes towards proliferation. Furthermore, the ratio of CD4+/CD8+ T lymphocytes was significantly increased from 0.69 to 2.29 by treatment with DGVL. Immunoblotting analyses revealed that the expression of Fas and FasL on the thymus was lower in mice in the DGVL treatment group than in the control mice. In conclusion, DGVL can inhibit tumor growth and protect tumor-induced apoptosis of the thymus, and the mechanism is closely associated with reduced cell death in the thymus and a Fas–FasL-dependent pathway.

Type 1 diabetes is a chronic autoimmune disease of beta cells in the islets of Langerhans, which are responsible for making insulin. Even with insulin therapy, inflammatory complications will develop in the long term. The present study examines changes in serum levels of interleukin (IL)-6, IL-17, IL-10, tumor necrosis factor (TNF)-α, interferon (IFN)-γ, C-peptide, Insulin as well as fasting blood sugar (FBS) in control, diabetic and diabetic treated with curcumin groups. Thirty inbred C57BL /6 mice were randomly divided into three groups of 10 mice: group A consisted of healthy mice receiving citrate buffer, group B included a group of diabetic mice, and group C was a group of diabetic mice treated with curcumin. The cytokine levels were measured in the supernatant of stimulated splenocytes using enzyme -linked immunosorbent assay (ELISA). Radioimmunoassay was used to measure insulin and c-peptide levels. The FBS was measured by an automatic glucometer device. The levels of IL-6, IL-17, and IFN-γ, as well as FBS, was significantly decreased in the treated group with curcumin compared to the diabetic group mice (p<0.05). TNF-α levels were also low, but the difference was not significant. IL-10, plasma C-peptide, and insulin significantly increased in the supernatant of stimulated splenocytes of treated diabetic group than in the diabetic group (p<0/05). According to the results, this study supports the anti-diabetic and anti-inflammatory effects of curcumin; however, more studies are needed to investigate theeffects of curcumin and the dose-response relationship in this disease.

The present study was undertaken to evaluate serum levels of pro-inflammatory cytokines in Tunisian older adults and to examine the relationships between inflammatory marker levels, geriatric, and biochemical parameters. A cross-sectional study was conducted in a population of Tunisian older adults (N = 141, aged 65 and over). Patients were recruited from the Department of Internal Medicine, Fattouma Bourguiba University Hospital (Monastir, Tunisia) and from a nursing home (Sousse, Tunisia). Comprehensive geriatric assessment, history taking and examination including functional and nutritional assessment were done for each participant. Enzyme-linked immunosorbent assay (ELISA) test was used to measure serum cytokine (TNF-α, IL-8, IL-6) levels. The modified Short Emergency Geriatric Assessment score (SEGAm) were used to classify patients as 51 very-frail, 40 frail, and 50 non-frail. The age of the participants (80 men, 61 women) ranged from 65 to 97 years. Serum levels of TNF-α, IL-8 and C-reactive protein (CRP) were significantly higher in very-frail participants compared to frail and non-frail ones. However, no significant differences in IL-6 levels were detected among frailty groups. After adjustment for age, CRP and IL-8 levels remained significantly associated with frailty. Analysis of the receiver operating characteristic (ROC) curve corresponding to IL-8 showed an area under the curve of 0.7 (p = 0.003; 95% CI [0.58–0.81]) and a predictive threshold of 5.27 pg/ml. Positive correlations were found between frailty score, IL-6, and IL-8 levels. In addition, a significant positive correlation was observed between IL-8 levels and Timed Up and Go test results. However, a negative correlation was observed between Mini Nutritional Assessment Short-Form score, IL-6 and CRP levels, as well as between Activities of Daily Living score and serum levels of TNF-α, IL-6, and CRP. In conclusion, the key findings of this study collectively support a role of pro-inflammatory cytokines, TNF-α, CRP, and especially IL-8 in the development of frailty in older adults.

PURPOSE: To investigate the effects of pentoxifylline (PTX) in experimental acute pancreatitis (AP) starting drug administration after the induction of the disease. METHODS: One hundred male Wistar rats were submitted to taurocholate-induced AP and divided into three groups: Group Sham: sham-operated rats, Group Saline: AP plus saline solution, and Group PTX: AP plus PTX. Saline solution and PTX were administered 1 hour after induction of AP. At 3 hours after AP induction, peritoneal levels of tumor necrosis factor (TNF)-α, and serum levels of interleukin (IL)-6 and IL-10 levels were assayed by Enzyme-Linked Immunosorbent Assay (ELISA). Determinations of lung myeloperoxidase activity (MPO), histological analysis of lung and pancreas, and mortality study were performed. RESULTS: PTX administration 1 hour after induction of AP caused a significant decrease in peritoneal levels of TNF-α and in serum levels of IL-6 and IL-10 when compared to the saline group. There were no differences in lung MPO activity between the two groups with AP. A decrease in mortality was observed in the PTX treatment compared to the saline group. CONCLUSIONS: Administration of PTX after the onset of AP decreased the systemic levels of proinflammatory cytokines, raising the possibility that there is an early therapeutic window for PTX after the initiation of AP.

Purpose: To investigate the antioxidant and anti-neuroinflammatory potential of Saussurea lappa Clarke (SLC-EA) extract in LPS-stimulated BV-2 microglial cells.Methods: Cell viability was measured by using the 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay while antioxidant activity was evaluated by using the DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity. Lipopolysaccharide (LPS) was used to stimulate BV-2 microglia. Griess assay was employed to assess nitric oxide (NO) production. iNOS (inducible NO synthase) expression and TNF-α (tumor necrosis factor-alpha) cytokine production were measured by ELISA (enzyme-linked immunosorbent assay) and immuno blot analysis, respectively.Results: Pretreatment of 100 mg/ml of SLC-EA (p < 0.001) was inhibited Nitric Oxide (NO) by 1 ug/ml of LPS-treated murine BV-2 cells. The expression of iNOS and TNF-α were reduced by SLC-EA concentration dependent manner (p < 0.001 at 100 mg/ml). SLC-EA were scavenged 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radicals in a dose-dependent manner with an IC50 value of approximately 51.4 μg/ml.Conclusion: The results indicate that SLC-EA extract exhibits strong antioxidant properties and inhibits excessive pro-inflammatory cytokine due probably to the antioxidant phenolic compounds present in SLC-EA extract. Further work in exploring the in-depth mechanisms of SLC-EA extract in regulating inflammatory signaling pathways in treating neuroinflammatory diseases is necessary.
