Mechanism of inflammatory response and therapeutic effects of stem cells in ischemic stroke:current evidence and future perspectives

Ischemic stroke is a leading cause of death and disability worldwide,with an increasing trend and tendency for onset at a younger age.China,in particular,bears a high burden of stroke cases.In recent years,the inflammatory response after stroke has become a research hotspot:understanding the role of inflammatory response in tissue damage and repair following ischemic stroke is an important direction for its treatment.This review summarizes several major cells involved in the inflammatory response following ischemic stroke,including microglia,neutrophils,monocytes,lymphocytes,and astrocytes.Additionally,we have also highlighted the recent progress in various treatments for ischemic stroke,particularly in the field of stem cell therapy.Overall,understanding the complex interactions between inflammation and ischemic stroke can provide valuable insights for developing treatment strategies and improving patient outcomes.Stem cell therapy may potentially become an important component of ischemic stroke treatment.

Pro and anti-inflammatory diets as strong epigenetic factors in inflammatory bowel disease

Inflammatory bowel disease(IBD)is the consequence of a complex interplay between environmental factors,like dietary habits,that alter intestinal microbiota in response to luminal antigens in genetically susceptible individuals.Epigenetics represents an auspicious area for the discovery of how environmental factors influence the pathogenesis of inflammation,prognosis,and response to therapy.Consequently,it relates to gene expression control in response to environmental influences.The increasing number of patients with IBD globally is indicative of the negative effects of a food supply rich in trans and saturated fats,refined su-gars,starches and additives,as well as other environmental factors like seden-tarism and excess bodyweight,influencing the promotion of gene expression and increasing DNA hypomethylation in IBD.As many genetic variants are now associated with Crohn's disease(CD),new therapeutic strategies targeting modi-fiable environmental triggers,such as the implementation of an anti-inflammatory diet that involves the removal of potential food antigens,are of growing interest in the current literature.Diet,as a strong epigenetic factor in the pathogenesis of inflammatory disorders like IBD,provides novel insights into the pathophysio-logy of intestinal and extraintestinal inflammatory disorders.

Crocus sativus L.produces anti-inflammatory effects and regulates the NLRP3–NF-κB pathway

Objective:This study aimed to evaluate the anti-inflammatory effects of petal and stamen extracts of saffron crocus(Crocus sativus)and explore the underlying mechanism.Methods:Local and systemic inflammation models were used to investigate the anti-inflammatory effects of C.sativus.A xyleneinduced inflammation model or lipopolysaccharide(LPS)-induced inflammation model was used in this study.C.sativus petal and stamen extracts were each administered to the mice in the xylene and LPS models by gavage for 14 d at 0.1 and 0.4 g/kg doses,respectively.Enzyme-linked immunosorbent assay(ELISA)was used to measure the concentrations of tumor necrosis factor(TNF)-αand interleukin(IL)-1βin mouse serum.Hematoxylin and eosin(H&E)staining was used to observe the pathological changes in the ear in the xylene-induced inflammation model and in the spleen in the LPS-induced inflammation model.NOD-like receptor thermal protein domain associated protein 3(NLRP3)protein levels within the nuclear factor-kappa B(NF-κB)pathway were assessed using western blotting.RAW264.7 cells were treated with LPS(5μg/mL)and LPS+C.sativus(0.05,0.1,and 0.2 mg/mL)for 24 h,and a Cell Counting Kit-8 was used to measure cell proliferation.Changes in NLRP3 and NF-κB levels were evaluated by western blotting.Results:Petal and stamen extracts of C.sativus attenuated the anti-inflammatory effects in local or systemic inflammatory models and repaired pathological changes in the ear in the xylene-induced inflammation model and spleen in the LPS-induced inflammation model.These extracts also decreased the concentrations of TNF-αand IL-1βin the mouse serum in the LPS-induced inflammation model.C.sativus downregulated NLRP3 protein level through the NF-κB pathway and downregulated LC-3 and BECLIN1 in vivo and in vitro.Carbonyl Cyanide3-ChloroPhenylhydrazone(CCCP)weakened the effects of C.sativus on the NLRP3–NF-κB pathway.Conclusion:C.sativus has anti-inflammatory effects and regulates the NLRP3-NF-κB pathway.

Prognostic impact of inflammatory and nutritional biomarkers in pancreatic cancer

Pancreatic cancer is usually associated with a poor prognosis.Surgery is the main curative treatment but pancreatic operations are aggressive and new tools that help clinicians to predict surgical and prognostic outcomes are necessary.Lu et al recently published a retrospective,single centre cohort study evaluating the impact of seven nutritional and inflammatory markers in pancreatic cancer surgical patients:The albumin-to-globulin ratio,prognostic nutritional index(PNI),systemic immune-inflammation index(SII),neutrophil-to-lymphocyte ratio(NLR),platelet-to-lymphocyte ratio(PLR),nutritional risk index,and the geriatric nutritional risk index.A significant correlation was found between the PNI,SII,NLR,and PLR and a hospital discharge of less than 15 days.In a univariable analysis,PNI,SII,NLR and PLR were significantly related to recurrence-free survival and,in a multivariable analysis PNI was associated with overall survival.Various meta-analyses corroborate the results in terms of prognosis but individual studies are discordant on their usefulness.Besides,the cut-off values for these markers vary significantly between studies and there are no clinical trials comparing them to identify the most relevant ones.These are limitations when implementing nutritional and inflammatory biomarkers into clinical practice and further studies are needed in order to answer these questions.

Gut virome:New key players in the pathogenesis of inflammatory bowel disease

Inflammatory bowel disease(IBD)is a chronic inflammatory illness of the intes-tine.While the mechanism underlying the pathogenesis of IBD is not fully under-stood,it is believed that a complex combination of host immunological response,environmental exposure,particularly the gut microbiota,and genetic suscept-ibility represents the major determinants.The gut virome is a group of viruses found in great frequency in the gastrointestinal tract of humans.The gut virome varies greatly among individuals and is influenced by factors including lifestyle,diet,health and disease conditions,geography,and urbanization.The majority of research has focused on the significance of gut bacteria in the progression of IBD,although viral populations represent an important component of the microbiome.We conducted this review to highlight the viral communities in the gut and their expected roles in the etiopathogenesis of IBD regarding published research to date.

Biologics in the management of pediatric inflammatory bowel disease:When and what to choose

Pediatric inflammatory bowel disease(PIBD)is a chronic inflammatory disorder of the gastrointestinal tract,with rising global incidence and prevalence.Over the past two decades,biologics have added to the therapeutic armamentarium and revolutionized the approach to treatment of inflammatory bowel disease.The available biologics include monoclonal antibodies which target inflammatory cytokines(anti-tumor necrosis factor alpha,anti-interleukin 12/23)or recruitment of leucocytes to the gastrointestinal tract(anti-alpha4beta7 integrin)and small molecules(Janus kinase inhibitors,sphingosine 1-phosphate-inhibitors)which modify the proinflammatory signaling.Considering their potential disease-modifying ability,recent pediatric guidelines from the West have advocated upfront use of biologics in appropriate clinical scenarios as a top-down approach rather than the conventional step-up approach.Although real-world studies are available regarding the clinical efficacy of biologics in PIBD,there is paucity of long-term outcome and safety data in children.Also,little information is available about the best approach in the newly industrialized-developing countries where PIBD is rising but at the same time,infections are prevalent and resources are limited.In this review,we summarize the efficacy and safety profile of biologics and small molecule drugs and discuss the challenges in the management of PIBD,especially in the developing world,and future directions.

Antibacterial, Anti-Inflammatory and Antioxidant Activities of an ACAZY Herbal Formula Used in Traditional Medicine to Treat Respiratory Infections

ACAZY is a plant formula used in traditional medicine in Burkina Faso to treat respiratory infections. After phytochemical analysis, this study evaluated extracts’ anti-inflammatory, antioxidant and antibacterial properties from the ACAZY recipe. Three extractions, an aqueous macerate (AM), an aqueous decoction (AD) and an hydroethanolic macerate (HEM) of the ACAZY recipe powder were carried out. Phytochemical screening of the extracts was carried out using high-performance thin-layer chromatography (HPTLC) and the determination of phenolic compounds. The anti-inflammatory potential was assessed in vitro using pro-inflammatory enzyme inhibition tests. 2,2-Diphenyl-1-picrylhydrazyl (DPPH) and Ferric-reducing antioxidant power (FRAP) antioxidant properties were also determined. The antibacterial activity was evaluated on Staphylococcus aureus and Streptococcus pneumoniae strains. Phytochemical analysis revealed the presence of flavonoids, saponins, tannins, anthracenosids, sterols and triterpenes in the extracts. The extracts inhibited pro-inflammatory enzymes by more than 40% at only 100 µg/mL. The extracts also showed potent antibacterial activity with a minimum inhibitory concentration 1 mg/mL on Staphylococcus aureus and 2 mg/mL on Streptococcus pneumoniae. The extracts in the ACAZY formula have shown anti-inflammatory and antioxidant properties in vitro. The AD also showed an antibacterial activity. This justifies its use in traditional medicine to treat acute respiratory infections.

Safety and in Vivo Anti-Inflammatory Activity of Ethanolic Extract of Ficus umbellata (Vahl.) Leaves

Toxicity is the totality of adverse effects, which can be functional and morphological lesions in a living organism, caused by a substance introduced in relatively high single doses or in small, repeated doses. The aim of this study was to assess the OECD-recommended acute oral toxicity and anti-inflammatory activity of ethanolic extract of Ficus umbellata leaves. Animals were given a single oral dose of 1000, 3000 and 5000 mg/Kg body weight (BW) of the extract. For the anti-inflammatory activity test, rats were given the ethanolic extract of F. umbellata leaves at doses of 100, 300 and 500 mg/Kg or aspirin® at a concentration of 100 mg/Kg PC orally, one hour before injection of 0.05 ml of 1% formalin under the plantar fascia of the rat’s right hind paw. Paw volume measurements were taken one, two and three hours after formalin injection, using an electronic caliper. After 14 days of observation, no deaths were observed in treated rats. The LD50 of ethanolic extract of Ficus umbellata leaf powder is greater than 5000 mg/Kg body weight. This extract has no significant effects on hematological parameters and on the main markers of nephrotoxicity and hepatotoxicity for a single dose of less than 5000 mg/Kg PC. It reduces formalin-induced edema. Evaluation of the percentage inhibition showed that the extract had greater anti-inflammatory activity at 3 hours after the start of the experiment. However, better inhibition of inflammatory oedema of the paw of rats treated with 500 mg/Kg was observed at 5 hours after the start of the experiment, with a percentage inhibition of 69.23 ± 1.02, compared with the reference group treated with aspirin® 100 mg/Kg, which showed an inhibition of 63.50 ± 0.98. These results show that F. umbellata leaves possess anti-inflammatory activity, which would justify their use in traditional African medicine to prevent or treat inflammation.

Cardiovascular involvement in multisystem inflammatory syndrome in children and midterm follow-up from a pediatric tertiary center in India

BACKGROUND In multisystem inflammatory syndrome in children(MIS-C)with coronavirus disease 2019,there was paucity of data from low-income and middle-income countries on cardiovascular involvement and its longitudinal outcomes.We planned to estimate the pattern of cardiovascular involvement among children with MIS-C and its mid-term outcomes.AIM To determine association between cardiovascular abnormalities and clinical and laboratory parameters.To study the time-line for resolution of various abnormalities.METHODS In this prospective study done in a tertiary care hospital,270 were recruited from June 2020 to January 2022.Baseline demographic data and clinical presentation were recorded.Laboratory parameters and echocardiography were done at admission.Follow-up was done at 2 weeks,3 months,6 months and 1 year after diagnosis.Descriptive statistics were used for parametric and non-parametric data.Risk factors were identified by multivariate regression analysis.RESULTS The 211(78.2%)had cardiac involvement and 102 needed intensive care unit(ICU)admission.Cardiovascular abnormalities observed were shock 123(45.6%),coronary dilatation 28(10.4%),coronary aneurysm 77(28.5%),left ventricular(LV)dysfunction 78(29.3%),mitral regurgitation(MR)77(28.5%)and pericardial effusion 98(36.3%).Coronary artery aneurysm/dilatation during follow-up at 2 weeks and 1 year were 25.7%and 0.9%respectively.Multivariate regression analysis revealed breathlessness[odds ratio(OR)=3.91,95%CI:1.25-12.21,P=0.019]and hi-flow nasal cannula(HFNC)support(OR=8.5,95%CI:1.06-68.38,P=0.044)as predictors of cardiovascular involvement.Higher mean age(OR=1.16,95%CI:1.02-1.32,P=0.026),breathlessness(OR=4.99,95%CI:2.05-12.20,P<0.001),gallop(OR=4.45,95%CI:0.41-2.52,P=0.016),MR(OR=3.61,95%CI:1.53-8.53,P=0.004)and invasive ventilation(OR=4.01,95%CI:1.28-12.58,P=0.017)were predictive of LV dysfunction.Altered sensorium(OR=4.96,95%CI:2.23-11.02,P<0.001),headache(OR=6.61,95%CI:1.46-29.92,P=0.014),HFNC(OR=7.03,95%CI:2.04-24.29,P=0.002),non-rebreathing mask usage(OR=21.13,95%CI:9.00-49.61,P<0.001)and invasive ventilation(OR=5.64,95%CI:1.42-22.45,P=0.014)were risk factors for shock.Anemia was a risk factor for coronary involvement(OR=3.09,95%CI:1.79-5.34,P<0.001).CONCLUSION Significant number of children with MIS-C had cardiovascular involvement contributing to higher ICU management.Although shock resolved quickly,resolution of ventricular function and coronary abnormalities were slower,and hence warrants a structured long-term follow-up protocol.

Roles of Community Pharmacists in Screening and Disseminating of Information about Non-Steroidal Anti-Inflammatory Drugs Risks: Implications for Drug Safety Assessment

Background: The increasing use of non-steroidal anti-inflammatory drugs (NSAIDs) both on prescription and over the counter raises a major global health concern because of the risks associated with their use if no proper guidance is given by the health care provider. This study assessed the roles of community pharmacists in screening and disseminating information about the risks associated with NSAID use in Zambia. Methodology: This was a national cross-sectional study in which a structured self-administered questionnaire was administered to 245 registered community pharmacists in Zambia. Stata/BE, version 15.1 (Stata Corporation, College Station, Texas, USA) and multivariate logistic regression model was used to determine factors associated with information dissemination about ADRs of NS-NSAIDs. Results: 231 of the 245 distributed questionnaires were returned giving a response rate of 94.3%. All (100%) participating community pharmacists claimed to have practiced dispensing NSAIDs. However, only 26 (11.0%) and 71 (30.8%) regularly screened for risk factor of selective COX-2 NSAIDS (SC2-NSAIDS) and non-selective NSAIDS (NS-NSAIDs) respectively. Information dissemination on adverse drug reactions (ADRs) of SC2-NSAIDS was regularly provided by only 22 (9.5%) of pharmacists while that of NS-NSAIDs was regularly provided by 49 (21.2%). In the multivariate logistic regression model, being the owner of a pharmacy (AOR: 5.4, CI: 1.84 - 16.4) was significantly associated with information dissemination about ADRs of NS-NSAIDs while an hour increase in the working hours per day (AOR: 0.9, CI: 0.64 - 0.95) was associated with less likelihood of information dissemination. Conclusion: Pharmacists working in community pharmacies in Zambia did not regularly screen and disseminate information about the risks associated with NSAID use. Therefore, pharmacists should be able to screen and monitor patients at risk and be aware of the majority of risk factors while dispensing NSAIDs to minimize the associated complications.

Preprocessing and Efficacy Analysis of Comprehensive Anti-Inflammatory Treatment for Lymphedema in Patients with Irritating Contact Dermatitis

Objective: To explore the pre-treatment and efficacy analysis of comprehensive anti-inflammatory treatment for lymphedema in patients with irritating contact dermatitis. Method: Convenience sampling method was used to observe the skin of 160 patients with upper limb lymphedema admitted to the lymphedema outpatient department of our hospital. They were divided into an observation group (80 cases) and a control group (80 cases), and both groups received a course of comprehensive anti-inflammatory treatment (20 treatments). The control group received routine skin care;On the basis of the control group, the observation group received pre-treatment of the affected limb skin: Laofuzi herbal ointment was applied externally to the prone areas of irritating contact dermatitis (such as the upper arm, inner forearm, and cubital fossa). Result: The incidence of irritating contact dermatitis in the observation group was significantly lower than that in the control group (P 0.05). Patients in the observation group felt significantly better in terms of comfort, skin moisture, and itching relief after being wrapped with low elasticity bandages than those in the control group (P Conclusion: Preventive treatment can effectively reduce the incidence of irritating contact dermatitis, prolong the time of stress treatment, thereby increasing efficacy and improving patient compliance.

Tamanu Oil in Acne Management: Potential Anti-Inflammatory and Wound-Healing Properties for Scar Reduction

Tamanu oil, derived from the nuts of Calophyllum inophyllum, has gained increasing attention for its potential in acne management due to its purported anti-inflammatory and wound-healing properties. This analysis evaluates the efficacy of tamanu oil in acne treatment with a specific focus on its impact on inflammation and scar reduction. The novelty of this research lies in its comprehensive analysis of tamanu oil’s dual mechanism of action: reducing acne-related inflammation and promoting the healing of acne scars. Clinical trials and laboratory analyses were conducted to assess the oil’s effectiveness in diminishing erythema, swelling, and post-acne scarring compared to conventional treatments. Preliminary findings demonstrate that tamanu oil significantly reduces inflammation and accelerates wound healing, potentially offering a promising adjunct or alternative to standard acne therapies. Future research should aim to optimize formulation and application protocols, long-term effects, and comparative therapeutic efficacy with other anti-inflammatory agents. Tamanu oil offers a novel and effective approach to acne management, with potential advantages that go beyond inflammation reduction to include enhanced scar reduction, making it a subject that warrants further investigation.

Synthesis and Anti-inflammatory Activity of 2-(E)-(4-Hy-droxy-3-methoxybenzylidene)-5-(N-Substituted aminomethyl)Cyclopentanones

A series of 2 (E) (4 hydroxy 3 methoxybenzylidene) 5 (N substituted ami nomethyl) cyclopentanones was synthesized and evaluated for the anti inflammatory activity. All of the target compounds were confirmed by spectral analysis and elemental analysis. Preliminary pharmacological tests showed that several compounds exerted appreciable inhibitory effect on xylene induced ear edema in mice and that alteration of the substituents of anilines had significant influence in anti inflammatory potency.

Does aspirin or non-aspirin non-steroidal anti-inflammatory drug use prevent colorectal cancer in inflammatory bowel disease?

AIM: To determine whether aspirin or non-aspirin nonsteroidal anti-inflammatory drugs(NA-NSAIDs) prevent colorectal cancer(CRC) in patients with inflammatory bowel disease(IBD).METHODS: We performed a systematic review and meta-analysis. We searched for articles reporting the risk of CRC in patients with IBD related to aspirin or NANSAID use. Pooled odds ratios(OR) and 95%CIs were determined using a random-effects model. Publication bias was assessed using Funnel plots and Egger's test. Heterogeneity was assessed using Cochran's Q and the I2 statistic.RESULTS: Eight studies involving 14917 patients and 3 studies involving 1282 patients provided data on the risk of CRC in patients with IBD taking NA-NSAIDs and aspirin respectively. The pooled OR of developing CRC after exposure to NA-NSAIDs in patients with IBD was 0.80(95%CI: 0.39-1.21) and after exposure to aspirin it was 0.66(95%CI: 0.06-1.39). There was significant heterogeneity(I2 > 50%) between the studies. There was no change in the effect estimates on subgroup a na ly s e s o f t he po pulat io n s t udie d o r w he t he r adjustment or matching was performed.CONCLUSION: There is a lack of high quality evidence on this important clinical topic. From the available evidence NA-NSAID or aspirin use does not appear to be chemopreventative for CRC in patients with IBD.

Anti-anaphylactic and anti-inflammatory activities of a bioactive alkaloid from the root bark of Plumeria acutifolia Poir

Objective:To investigate the anti-anaphylactic,anti-inflammatory and membrane stabilizing properties of plumerianine(compound 1)isolated from the root bark of Plumeria acuifolia Poir.Methods:The anti-anaphylactic activity of compound 1(10,25 and 50 mg/kg)was studied by using models such as passive cutaneous anaphylaxis,passive paw anaphylaxis and its antiinflammatory activity against carrageenin induced paw edema and cotton pellet granuloma in albino rats was also investigated using ketotifen and indomethacin as reference drugs.Results:A dose-dependent beneficial effect was observed on leakage of evans blue dye in skin challenged with antigen and on paw anaphylaxis induced by antiserum.The compound 1 also exhibited significant(P<0.01)inhibition of rat paw edema and granuloma tissue formation,including significant protection of RBC against the haemolytic effect of hypotonic solution,an indication of membrane-stabilizing activity.Conclusions:Anti-anaphylactic activity of compound 1 may be possibly due to inhibition of the release of various inflammatory mediators.Anti-inflammatory activity of compound may be related to the inhibition of the early phase and late phase of inflammatory events.

Evaluation of the anti-inflammatory activity of extract of Vernonia Amygdalina

Objective:To investigate the anti-inflammatory activity of the extract of Vernonia amygdalina (V.A).Methods:Inflammatory response was induced by topical application of croton oil dissolved in suitable vehicle on the rat ear.After 6 hrs,cutting out the ear quantitated the response.The cut ear was weighed and the increase in weight relative to control group was evaluated.Results:When co-applied with croton oil to the rat ear extract of V.A.produced a reduction in the inflammatory response when croton oil alone was applied to the rat ear.The extract produced(69.1 +2.0)%reduction of the inflammatory response produced by croton oil alone,lower than the reduction of the inflammatory response produced by acetyl salicylic acid[(71.1±2.0)%].Conclusions:This finding suggests that extract of V.A.exhibits antiinflammatory activity and may explain the usefulness of the leaves of this plant in the treatment of inflammatory disease conditions by traditional healers.

Significant risk and associated factors of active tuberculosis infection in Korean patients with inflammatory bowel disease using anti-TNF agents

AIM:To evaluate the incidence and risk factors of Korean tuberculosis(TB) infection in patients with inflammatory bowel disease(IBD) undergoing anti-TNF treatment.METHODS:The data of IBD patients treated with anti-TNFs in 13 tertiary referral hospitals located in the southeastern region of Korea were collected retrospectively.They failed to show response or were intolerant to conventional treatments,including steroids or immunomodulators.Screening measures for latent TB infection(LTBI)and the incidence and risk factors ofactive TB infection after treatment with anti-TNFs were identified.RESULTS:Overall,376 IBD patients treated with antiTNF agents were recruited(male 255,mean age of anti-TNF therapy 32.5±13.0 years);277 had Crohn’s disease,99 had ulcerative colitis,294 used infliximab,and 82 used adalimumab.Before anti-TNF treatment,screening tests for LTBI including an interferon gamma release assay or a tuberculin skin test were performed in 82.2%of patients.Thirty patients(8%)had LTBI.Sixteen cases of active TB infection including one TB-related mortality occurred during 801 personyears(PY)follow-up(1997.4 cases per 100000 PY)after anti-TNF treatment.LTBI(OR=5.76,95%CI:1.57-21.20,P=0.008)and WBC count<5000 mm3(OR=4.5,95%CI:1.51-13.44,P=0.007)during follow-up were identified as independently associated risk factors.CONCLUSION:Anti-TNFs significantly increase the risk of TB infection in Korean patients with IBD.The considerable burden of TB and marked immunosuppression might be attributed to this risk.

The anti-inflammatory effects of asiatic acid in lipopolysaccharide-stimulated human corneal epithelial cells

AIM： To investigate the anti-inflammatory effects of asiatic acid（AA） on lipopolysaccharide（LPS）-induced inflammatory response in human corneal epithelial cells（HCECs）.METHODS： Cell viability was measured using a cell counting kit-8（CCK-8） assay.Quantitative real-time polymerase chain reaction（qR T-PCR） was used to determine the mR NA expression of interleukin-8（IL-8）,interleukin-6（IL-6）,interleukin-1β（IL-1β）,tumor necrosis factor-alpha（TNF-α）,and transforming growth factor-β（TGF-β） in HCECs.Intracellular reactive oxygen species（ROS） was measured using the ROS assay kit.Glutathione（GSH） concentration was measured using the total GSH assay kit.Akt1 and Akt phosphorylation（p-Akt1） levels were measured by Western blotting and immunofluorescence.RESULTS： AA induced toxicity at high concentrations and significantly stimulated the proliferation of HCECs at concentrations of 20 μmol/L for 1h.LPS at concentrations of 300 ng/mL for 1h significantly stimulated the mR NA expression of IL-8,IL-6,IL-1β,TNF-α,and TGF-β in HCECs,while the stimulation effects were significantly inhibited by AA（20 μmol/L）.In addition,AA was found to decrease the content of ROS,increase GSH generation,and also inhibit LPS-induced p-Akt in HCECs.CONCLUSION： AA decreases the generation of inflammatory factors IL-8,IL-6,IL-1β,TNF-α,and TGF-β in LPSstimulated HCECs.AA significantly inhibites the intracellular concentrations of ROS and increases GSH generation.AA also inhibites LPS-induced p-Akt in HCECs.These findings reveal that AA has anti-inflammation effects in LPS-stimulated HCECs.

Ischemic preconditioning produces more powerful anti- inflammatory and cardioprotective effects than limb remote ischemic postconditioning in rats with myocardial ischemia-reperfusion injury

Background Both ischemic preconditioning （IPC） and limb remote ischemic postconditioning （LRIPOC） have been shown to possess significantly different cardioprotective effects against the myocardial ischemia reperfusion injury （IRI）, but no study has compared the anti-inflammatory effects of IPC and LRIPOC during myocardial IRI process. We hypothesized that IPC and LRIPOC would produce different anti-inflammatory effects in an in vivo rat model with myocardial IRI.

Anti-integrin therapy for inflammatory bowel disease

In inflammatory bowel disease(IBD), tumor necro-sis factor plays an important role in mediating infla-mmation, but several other pathways are also involved in eliciting an inflammatory response. One such pathway is the invasion of the intestinal mucosa by leukocytes. Leukocytes within the systemic circulation move to sites of inflammation, and blocking this pathway could be an important treatment strategy for IBD. Anti-integrin therapy blocks the action of integrin on the surface of circulating immune cells and endothelial cell adhesion molecules, thereby inhibiting the interactions between leukocytes and intestinal blood vessels. Natalizumab, which acts on α4-integrin, was the first such drug to be approved for Crohn's disease, but its use is limited due to the risk of progressive multifocal leukoencephalopathy. Vedolizumab produces few systemic adverse effects because it acts on gut-trophic α4β7 integrin, and has been approved and is being used to treat IBD. Currently, several anti-integrin drugs, including etrolizumab, which acts on β7-integrin, and PF-00547569, which targets mucosal addressin cell adhesion molecule-1, are undergoing clinical trials and the results are being closely watched.
