Biomaterials-based anti-inflammatory treatment strategies for Alzheimer's disease

The current therapeutic drugs for Alzheimer's disease only improve symptoms,they do not delay disease progression.Therefo re,there is an urgent need for new effective drugs.The underlying pathogenic factors of Alzheimer's disease are not clear,but neuroinflammation can link various hypotheses of Alzheimer's disease;hence,targeting neuroinflammation may be a new hope for Alzheimer's disease treatment.Inhibiting inflammation can restore neuronal function,promote neuro regeneration,reduce the pathological burden of Alzheimer's disease,and improve or even reverse symptoms of Alzheimer's disease.This review focuses on the relationship between inflammation and various pathological hypotheses of Alzheimer's disease;reports the mechanisms and characteristics of small-molecule drugs(e.g.,nonsteroidal anti-inflammatory drugs,neurosteroids,and plant extracts);macromolecule drugs(e.g.,peptides,proteins,and gene therapeutics);and nanocarriers(e.g.,lipid-based nanoparticles,polymeric nanoparticles,nanoemulsions,and inorganic nanoparticles)in the treatment of Alzheimer's disease.The review also makes recommendations for the prospective development of anti-inflammatory strategies based on nanocarriers for the treatment of Alzheimer's disease.

Isolation and bioactivity screening of soy isoflavones from soybean glycolipids identifies daidzin as a promising anti-inflammatory agent

Background:Soybean has long been utilized in the realm of traditional Chinese medicine.One of its extracts,soybean glycolipids,serves as a vital by-product of soybean oil refining,but its chemical composition and pharmacological potential have yet to be fully elucidated.Methods:In this study,the chemical components were isolated,and the inhibitory effects of these isolates were explored in different zebrafish inflammatory models by survival rate,Histological examination assay and quantitative Real-time PCR assay.The cytotoxicity of daidzin in RAW264.7 cells was evaluated by cell viability assay,and the effect of daidzin on the release of inflammatory cytokines in RAW264.7 cells was detected by enzyme linked immunosorbent assay(ELISA).Western blotting,immunofluorescence assay and alpha7 nicotinic acetylcholine receptors siRNA transfection assay were used to further explore the anti-inflammatory mechanism of daidzin.Results:Four compounds(verticilloside,soya-cerebroside I,soya-cerebroside II and daidzin)were firstly isolated from the soybean glycolipids,among which verticilloside and daidzin inhibited the lipopolysaccharide,CuSO4-and tail cut-stimulated zebrafish inflammation.Noticeably,daidzin exhibited anti-inflammatory activities by increasing the survival rate,alleviating the inflammatory cells infiltration,and down-regulating the expression of pro-inflammatory cytokines and nuclear factor kappa-B,NF-kappa-B inhibitor alpha,and signal transducer and activator of transcription3 in zebrafish.Moreover,daidzin decreased the secretion of IL-6 and TNF-α,inhibited the nuclear translocations of nuclear factor kappa-B p65 and p-signal transducer and activator of transcription3 as well as the NF-kappa-B inhibitor alpha phosphorylation at Ser32 in RAW 264.7 cells.More importantly,it elevated the expression level of alpha7 nicotinic acetylcholine receptors in both zebrafish and RAW 264.7 cells,and the inhibitory effect of daidzin was attenuated after the addition of alpha7 nicotinic acetylcholine receptors siRNA.Conclusion:Our study revealed that daidzin inhibited inflammation by activating the cholinergic anti-inflammatory pathway and further inhibiting the nuclear factor kappa-B and signal transducer and activator of transcription3 signaling.At the same time,it also promotes the recycling of crude soybean glycolipids and supports the potential use of daidzin as a functional food or natural dietary anti-inflammatory agent.

Anti-inflammatory Mechanism of Yao Medicine Laggerae Alatae Herba

[Objectives]To study the anti-inflammatory effect of Laggerae Alatae Herba extract and its mechanism.[Methods]Inflammation models of xylene-induced ear edema in mice,acetic acid-induced increased permeability of abdominal capillaries in mice,and carrageenan-induced paw edema in mice were established;xylene-induced ear swelling model in bilateral adrenalectomized mice was established.The levels of MDA,NO and SOD in inflammatory tissues of paw were measured.[Results]Compared with the model group,the high and medium dose groups of Laggerae Alatae Herba extract had significant inhibitory effect on xylene-induced ear edema in mice,except for the low dose group(P>0.05);Laggerae Alatae Herba extract inhibited the increase of celiac capillary permeability induced by acetic acid and paw edema induced by carrageenan in mice.Compared with the model group,in the mice model with bilateral adrenal glands removed,the high and medium dose groups of Laggerae Alatae Herba extract could significantly inhibit the xylene induced ear swelling of the mice.The high and medium dose groups of Laggerae Alatae Herba extract could significantly decrease the levels of MDA and NO,and significantly increase the level of SOD in the paw tissue.[Conclusions]The Laggerae Alatae Herba extracts have anti-inflammatory activity,and the anti-inflammatory effect of the extracts does not depend on the hypothalamic-pituitary-adrenal axis(HPAA)system.In addition,the anti-inflammatory mechanism of Laggerae Alatae Herba extract is related to the decrease of MDA and NO and the increase of SOD.

Diabetic retinopathy:Role of inflammation and potential therapies for anti-inflammation

Diabetic retinopathy is a leading cause of blindness among working-age adults.Despite many years of research,treatment options for diabetic retinopathy remain limited and with adverse effects.Discovery of new molecular entities with adequate clinical activity for diabetic retinopathy remains one of the key research priorities in ophthalmology.This review is focused on the therapeutic effects of cannabidiol(CBD),a nonpsychoactive native cannabinoid,as an emerging and novel therapeutic modality in ophthalmology based on systematic studies in animal models of inflammatory retinal diseases including diabetic retinopathy-a retinal disease associated with vascular-neuroinflammation.Special emphasis is placed on novel mechanisms which may shed light on the pharmacological activity asso c iated with CBD preclinically.These include a selfdefence system against inflammation and neurodegeneration mediated by inhibition of equilibrat ive nucleoside transporter and activation of adenosine receptor by treatment with CBD.

Neuroprotective mechanisms of rutin for spinal cord injury through anti-oxidation and anti-inflammation and inhibition of p38 mitogen activated protein kinase pathway

Rutin has anti-inflammatory, antioxidant, anti-viral, anti-tumor and immune regulatory effects. However, the neuroprotective effects of rutin in spinal cord injury are unknown. The p38 mitogen activated protein kinase （p38 MAPK） pathway is the most important member of the MAPK family that controls inflammation. We assumed that the mechanism of rutin in the repair of spinal cord injury is associated with the inhibition of p38 MAPK pathway. Allen’s method was used to establish a rat model of spinal cord injury. The rat model was intraperitoneally injected with rutin （30 mg/kg） for 3 days. After treatment with rutin, Basso, Beattie and Bresnahan locomotor function scores increased. Water content, tumor necrosis factor alpha, interleukin 1 beta, and interleukin 6 levels, p38 MAPK protein expression and caspase-3 and -9 activities in T8–9 spinal cord decreased. Oxidative stress related markers superoxide dismutase and glutathione peroxidase levels increased in peripheral blood. Rutin exerts neuroprotective effect through anti-oxidation, anti-inflammation, anti-apoptosis and inhibition of p38 MAPK pathway.

Anti-inflammatory effects of Solanum procumbens on a low dose complete Freund's adjuvant-induced arthritis rat model

Objective:To investigate the anti-inflammatory and analgesic effects of Solanum procumbens on complete Freund’s adjuvantinduced arthritis rat models.Methods:We isolated and identified five compounds in the ethanolsoluble Solanum procumbens extract(SP)with anti-inflammatory effects,including ursolic acid,β-sitosterol,hexadecanoic acid,cisvaccenic acid,and vanillic acid.Additionally,we investigated the anti-inflammatory effects of SP on rheumatoid arthritis symptoms,including paw volumes,local temperatures,withdrawal latency,and mechanical withdrawal threshold at the hind paw and white blood cell(WBC)number from complete Freund’s adjuvant-induced arthritis rat models.Results:We have successfully established a complete Freund’s adjuvant-induced arthritis rat model at a low dose(1 mg/mL).SP extract significantly reduced paw volumes(P<0.05),prolonged withdrawal latencies(P<0.05),decreased local temperature,and increased the mechanical withdrawal threshold(P<0.05),but only SP extract at the dose of 300 mg/kg significantly decreased WBC numbers.Conclusions:SP extract could be a potential medication candidate with anti-inflammatory effects for arthritis,but it requires further investigation into the mechanism of the SP and its effectiveness on other models as well as clinical trials.

Anti-inflammation and anti-fibrosis actions of resveratrol on experimental pneumoconiosis

OBJECTIVE To investigate the therapeutic effects and related signaling pathways involved in the actions of resveratrol on experimental pneumoconiosis in vivo and in vitro.METHODS The pneumoconiosis animal model was induced by exposing male SD rats to 15mg·m-3 silica aerosol in an inhalation chamber system for 6h·d-1,5d·week-1 for up to 8 weeks.The vehicle or resveratrol(10or 20mg·kg-1)was preventively or remedially administered to the rats during or after the 4-or 8-week silica exposure(SE)period,respectively.After 4-,8-,and up to 14-week treatment,in vivo near-infrared fluorescence imaging analysis and histological analysis were performed to evaluate the pathological changes in rat lung.Inflammatory cytokines level in bronchoalveolar lavage fluid(BALF)was measured by ELISA testing,and the deposition of fibrotic collagen proteins in lung parenchyma was determined by western blotting and immunohistochemistry analysis.Microarray analysis was performed to screen the signaling pathways involved in the actions of resveratrol on pneumoconiosis in vitro models.Anti-inflammation action and signaling of resveratrol was evaluated on silica-stimulated rat alveolar macrophage,which is one of the crucial effector cells for silica-induced inflammatory response;anti-fibrosis action and signaling of resveratrol was evaluated on TGF-β-induced human lung fibroblast,which acts as a promoter in the later fibrotic process of pneumoconiosis.RESULTS Silica aerosol exposure significantly increased macrophage infiltration and matrix metalloproteinases activity in lung tissue concomitant with the increased levels of inflammatory mediators in BALF.Preventive treatment with resveratrol(20mg·kg-1·d-1)reversed all these biochemical indices as well as histopathological alterations induced by silica exposure.Post-SE resveratrol treatment mildly reduced silica-induced inflammatory response in rat lung with no statistical significance.In vitro study revealed that resveratrol could inhibit alveolar macrophage cell death and decrease the levels of IL-1β and TNF-αinduced by silica particle exposure to cultured alveolar macrophages.Resveratrol was further shown to inhibit the nuclear transition of NF-κB and formation of cleaved caspase-1.Encouragingly,resveratrol preventively attenuated the lung fibrosis,evidenced by less fibrotic nodules formation and collagen proteins expression.No significant improvement on lung fibrosis was observed with post-SE resveratrol treatment.Invitrostudy further demonstrated that resveratrol suppressed TGF-β-induced lung fibroblast proliferation and collagen deposition,concomitant with the depressed activity of TGF-β/Smad signaling in lung fibroblast.CONCLUSION Resveratrol shows the anti-inflammation and anti-fibrosis actions on experimental pneumoconiosis in vivo and in vitro models.The depression of NF-κB,NALP3-inflammasome,and TGF-β/Smad signaling pathways may be involved in the anti-inflammation and anti-fibrosis actions of resveratrol,respectively.Resveratrol could be a potential therapeutic agent for the intervention of pneumoconiosis.

Liaoqiao aqueous extract inhibits B16 melanoma growth involving MAPKs/Nrf2/HO-1 mediated anti-oxidation and anti-inflammation

Aim Forsythia suspensa （Thunb.） Vahl, Lianqiao in Chinese, is one of the most fundamental herbs in traditional Chinese medicine （TCM） with heat-clearing and detoxicating properties. In this study, we aimed to study the antitumor activity of Lianqiao aqueous extract against melanoma using cancer cell line-based in vitro and mouse allografl tumor in vivo models. Furthermore, we also investigated the underlying molecular mechanisms, par- ticularly the involvement of anti-inflammation and anti-oxidation properties in its antitumor activity. Methods The proliferation of cancer cells was measured by MTT assay. The transplanted B16-F10 melanoma in C57BL/6 mice were established and used for the evaluation of in vivo antitumor effect of LQ. Tumor growth was monitored twice a week. Ki67 and CD31 were used to detect cancer cell proliferation and angiogenesis in tumor, respectively. The anti-oxidative property of LQ was determined by measuring the levels of ROS, MDA and GSH. The anti-inflamma- tory effect of LQ was evaluated by measuring TNF-α and IL-6 using ELISA kits. Other protein expression was deter- mined by Western Blot. Results LQ strongly inhibited the growth of B16-F10 cells in vitro and the tumor growth in vivo. The survival time of tumor-bearing mice was significantly prolonged by LQ. LQ inhibited cancer cell prolif- eration and angiogenesis in tumor as evidenced by decreased expressions of Ki67 and CD31. Levels of ROS, MDA TNF-α and IL-6 decreased, while GSH increased in LQ treatment group, indicating a strong anti-oxidative and an- ti-inflammatory activity of LQ. The expression of antioxidant proteins Nff-2 and HO-1, tumor suppressors P53 and p-PTEN, and the MAPK pathways in tumor tissues were upregulated by LQ treatment. Conclusions LQ exhibited strong antitumor activity against B16-F10 murine melanoma both in vitro and in vivo. The antitumor effect of LQ in- volved the decreased oxidative stress and inflammation in tumor, which is closely related to the heat-clearing and detoxicating properties of LQ.

Marine natural products with anti-inflammation effects

The ocean possesses a complex setting with high pressure,high salinity,oligotrophy,low temperature and weak illumination conditions.To survive and evolve in such harsh surroundings,marine organisms metabolize a series of chemicals known as secondary metabolites which indicate structural and functional diversity to adapt interspecific survival competition.During recent decades,the anti-inflammatory property of marine natural products has come under scrutiny as inflammation involves in the vast majority of diseases.Correspondingly,a myriad of marine bioactive molecules including terpenes,polypeptides,polysaccharides,sterols and many others may bring a new insight into inflammation therapies with multifarious sources and minimal side effects.And a better understanding of their mechanisms of anti-inflammation may lead to better treatments for numerous diseases.Herein,the research progress of marine-derived anti-inflammation compounds and the relevant mechanisms were reviewed,to provide a basis for the research and development of anti-inflammatory marine drugs.

Prevalence and Predictors of Anxiety and Depression among Gynaecological Cancer Patients at a Tertiary Health Facility in Southern Nigeria

Background: Cancer patients frequently suffer from mental health problems because of their reactions to their cancer diagnosis, cancer type, treatment effects, recurrence, fear of the end-of-life, survival, and financial burden. Some hospitals have integrated mental health assessments into cancer care, but our centre has little experience with this practice. Aim and Objectives: To ascertain the prevalence and predictors of anxiety and depression in patients with gynaecological cancer at a tertiary health facility in southern Nigeria. Materials and Methods: This was a facility-based cross-sectional descriptive study of 75 women with histologically confirmed gynaecological cancer managed at the University of Port Harcourt Teaching Hospital, Port Harcourt, from January 1, 2022, to December 31, 2022. Individuals having a history of drug addiction, severe cognitive impairment, non-consenting patients, and those with communication difficulties were excluded from the study. A data collection form was used to obtain socio-demographic, reproductive, and clinical characteristics, while the Hospital Anxiety and Depression Scale (HADS) was used to assess for anxiety and depression. Data was analyzed using descriptive statistics to determine the association of variables with anxiety and depression. Results: Most 27 (36.0%) of the respondents were in 40 - 49 age group with a mean age of 50.4 ± 12.3 years. The study showed that 39 (52.0%) of the respondents exhibited symptoms of anxiety, of which 14 (35.9%) were mild, 20 (51.3%) had moderate anxiety and 5 (12.8%) experienced severe anxiety. In addition, 46 (61.3%) of them showed symptoms of depression, of which 17 (37.0%) were mild, 15 (32.6%) were moderate and 14 (30.4%) experienced severe depression. The ratio of respondents who showed anxiety to those that showed symptoms of depression was 5: 6. The factors associated with anxiety were partner’s educational level (X2 = 4.745, p = 0.029), parity (X2 = 6.651, p = 0.036) and duration of diagnosis (X2 = 8.321, p = 0.004), while partner’s educational level (X2 = 6.810, p = 0.009), parity (X2 = 7.129, p = 0.028), age of coitarche (X2 = 6.512, p = 0.039) and duration of diagnosis (X2 = 4.955, p = 0.026) were significantly associated with depression. Conclusion: More than half of the respondents experienced anxiety, while about two-thirds experienced depression. There is a need to incorporate psychological evaluation into the care of gynaecological cancer patients.

Experience of Patients Who Underwent Scheduled Gynaecological Surgery at the Bogodogo University Hospital, Burkina Faso

Introduction: Surgery can cause anxiety and worry, such as waking up in pain, being physically harmed or dying. This study aimed to assess the experience of patients undergoing planned gynaecological surgery in the Obstetrics Gynaecology and Reproductive Medicine department of the University Hospital Centre of Bogodogo. Patients and methods: This was a cross-sectional study with prospective data collection during the period from June 1 to August 31, 2018. The study population consisted of patients who received scheduled gynaecological surgery during the period. Results: Seventy-six (76) patients underwent scheduled surgery and 62 were included. During discussion with the gynaecologist, 58 patients (93.55%) were satisfied. When the surgery was announced, 41 patients (66.13%) were anxious. At the consultation with the anaesthetist 59 patients (95.16%) were satisfied with the discussions. Fifty-five patients (88.7%) were anxious on admission to the operating theatre. The quality of care was satisfactory for 61 patients (98.39%) and all patients were satisfied with the care team. Conclusion: Periodic evaluation of patients’ experiences should therefore be incorporated into care evaluation policies in health facilities in order to contribute to continuous improvement in the quality of medical and surgical care.
