Abstract Background Periodontitis is a complicated inflammatory disease that damages the tooth-supporting tissues, with limited pharmacotherapy available. Macrophage-targeting therapy is promising for inflammatory diseases. Resveratrol (RSV), a nonflavonoid polyphenol, is known for its anti-inflammatory and immunomodulatory effects. However, its medical application is limited by its poor stability and water-solubility, as well as its low bioavailability. Result A therapeutic resveratrol-loaded liposomal system (Lipo-RSV) was developed to treat periodontitis. The physical properties of Lipo-RSV and its ability to regulate macrophages were investigated. The results showed that Lipo-RSV had good biocompatibility and could re-educate the inflammatory macrophages from M1- to M2-like phenotype through activating p-STAT3 and downregulating p-STAT1. Besides, the Lipo-RSV could scavenge ROS and inhibit the NF-κB signal and inflammasomes, thereby reducing the pro-inflammatory cytokines IL-1β, IL-6, and TNF-α. Conclusion These results revealed that Lipo-RSV could be a potential therapeutic system for the antibiotic-free treatment for periodontal diseases. Graphical Abstract

PCOS as the most common endocrine disorder of women in their reproductive age affects between 5–15% of the female population. Apart from its cardinal symptoms, like irregular and anovulatory cycles, hyperandrogenemia and a typical ultrasound feature of the ovary, obesity, and insulin resistance are often associated with the disease. Furthermore, PCOS represents a status of chronic inflammation with permanently elevated levels of inflammatory markers including IL-6 and IL-18, TNF-α, and CRP. Inflammation, as discovered only recently, consists of two processes occurring concomitantly: active initiation, involving “classical” mediators including prostaglandins and leukotrienes, and active resolution processes based on the action of so-called specialized pro-resolving mediators (SPMs). These novel lipid mediator molecules derive from the essential ω3-poly-unsaturated fatty acids (PUFAs) DHA and EPA and are synthesized via specific intermediates. The role and benefits of SPMs in chronic inflammatory diseases like obesity, atherosclerosis, and Diabetes mellitus has become a subject of intense research during the last years and since PCOS features several of these pathologies, this review aims at summarizing potential roles of SPMs in this disease and their putative use as novel therapeutics.

Skullcapflavone II (SFII), a flavonoid derived from Scutellaria baicalensis, has been reported to have anti-inflammatory properties. However, its therapeutic potential for skin inflammatory diseases and its mechanism are unknown. Therefore, this study aimed to investigate the effect of SFII on TNF-α/IFN-γ-induced atopic dermatitis (AD)-associated cytokines, such as thymus- and activation-regulated chemokine (TARC) and macrophage-derived chemokine (MDC). Co-stimulation with TNF-α/IFN-γ in HaCaT cells is a well-established model for induction of pro-inflammatory cytokines. We treated cells with SFII prior to TNF-α/IFN-γ-stimulation and confirmed that it significantly inhibited TARC and MDC expression at the mRNA and protein levels. Additionally, SFII also inhibited the expression of cathepsin S (CTSS), which is associated with itching in patients with AD. Using specific inhibitors, we demonstrated that STAT1, NF-κB, and p38 MAPK mediate TNF-α/IFN-γ-induced TARC and MDC, as well as CTSS expression. Finally, we confirmed that SFII significantly suppressed TNF-α/IFN-γ-induced phosphorylation of STAT1, NF-κB, and p38 MAPK. Taken together, our study indicates that SFII inhibits TNF-α/IFN-γ-induced TARC, MDC, and CTSS expression by regulating STAT1, NF-κB, and p38 MAPK signaling pathways.

Abstract Background Non-Hodgkin’s lymphoma (NHL) is a malignant disease of lymphoid tissue. At present, chemotherapy is still the main method for the treatment of NHL. R-CHOP can significantly improve the survival rate of patients. Unfortunately, DOX is the main cytotoxic drug in R-CHOP and it can lead to adverse reactions. Therefore, it is particularly important to uncover new treatment options for NHL. Results In this study, a novel anti-tumor nanoparticle complex Nm@MSNs-DOX/SM was designed and constructed in this study. Mesoporous silica nanoparticles (MSNs) loaded with Doxorubicin (DOX) and anti-inflammatory drugs Shanzhiside methylester (SM) were used as the core of nanoparticles. Neutrophil membrane (Nm) can be coated with multiple nanonuclei as a shell. DOX combined with SM can enhance the anti-tumor effect, and induce apoptosis of lymphoma cells and inhibit the expression of inflammatory factors related to tumorigenesis depending on the regulation of Bcl-2 family-mediated mitochondrial pathways, such as TNF-α and IL-1β. Consequently, the tumor microenvironment (TME) was reshaped, and the anti-tumor effect of DOX was amplified. Besides, Nm has good biocompatibility and can enhance the EPR effect of Nm@MSNs-DOX/SM and increase the effect of active targeting tumors. Conclusions This suggests that the Nm-modified drug delivery system Nm@MSNs-DOX/SM is a promising targeted chemotherapy and anti-inflammatory therapy nanocomplex, and may be employed as a specific and efficient anti-Lymphoma therapy.

SummaryMonocytes play a central role in the inflammatory disease atherosclerosis. CD14+CD16+ monocytes are considered proinflammatory monocytes, as they have an increased capacity to produce proinflammatory cytokines, such as TNF-α, and are elevated in various inflammatory diseases. We hypothesized that patients with coronary artery disease (CAD) have increased levels of CD14+CD16+ monocytes, and that CD14+CD16+ monocytes are associated with inflammation markers. We investigated CD14+CD16+ monocytes in 247 patients with CAD and 61 control subjects using flow cytometry. In addition serum concentrations of TNF-α, IL-6, and Hs-CRP were assessed. Patients with CAD had higher levels of CD14+CD16+ monocytes than controls (13.6% versus 11.4%; p<0.001). Logistic regression analysis including quartiles of CD14+CD16+ monocytes showed that CD14+CD16+ monocytes were associated with prevalence of CAD (OR 4.9, 95% CI 2.5–19.1, for subjects in the fourth quartile in comparison to subjects in the first quartile). The association between CD14+CD16+ monocytes and CAD remained independently significant after adjustment for most potential confounders (OR 5.0, 95% CI 1.2-20.0). Serum concentrations of TNF-α were elevated in subjects within the highest quartiles of CD14+CD16+ monocytes (p=0.018). Our study showed that increased numbers of CD14+CD16+ monocytes are associated with coronary atherosclerosis and TNF-α. In accordance, recent animal studies suggest a possibly important role of these monocytes in the development of atherosclerosis.

Bad or very bad oral hygiene. It identifies the role of social factors in the manifestation of the disease. The hygiene index correlates with the periodontal index r=0.312, p=0.009. Conclusion: In Georgian population the inflammatory periodontal diseases have a incredibly high unsatisfactory hygenic status. The incidence of individuals is high, who undergo professional cleaning once or more rarely a year, and who use a circular movement, when brushing their teeth. Also who intake carbohydrates and fast and spicy foods, sweets, using of synthetic liquids and who smoke. A relation among inflammatory periodontal diseases, socio- economic status, and correlation of parents’ social status to oral care habits have been identified. Awareness of the need for dental services, the development of oral care habits, healthy diet, the prevention of manageable risk factors, hygiene, and professional cleaning of teeth is recommended for the prevention of periodontal inflammatory diseases.

Background. Periodontal tissues inflammatory diseases are widespread among young people. Objective. This study was aimed at elaborating the method to assess risks of periodontal inflammatory diseases and determining its efficacy depending on the state of dental tissues, gum tissues and sex.          Methods. The study included 182 students (93 men, 89 women) aged 19-29: 22 individuals had no lesions of hard dental tissues and no signs of periodontal disease; 51 individuals were found to have DMF index <6; 52 individuals – DMF index ≥6; 57 individuals were diagnosed with chronic catarrhal gingivitis. Primary groups were formed in autumn; re-examination was carried in spring. The research participants were assessed for detection of risks of periodontal inflammatory disease by the method developes by the authors (Patent UA 54041). Results. The study revealed that the risk of development of preiodontitis increases in individuals with high caries and gingivitis intensity. In spring, more individuals suffer from microbial imbalance in in the composition of gingival sulcus fluid and decrease in the mean stability coefficient value that indicates an increased risk of inflammatory periodontal disease development. Women were less likely to experience seasonal dysbiotic changes in the gingival sulcus fluid composition compared with men. Conclusions. The method suggested for assessment of the risk of periodontal inflammatory diseases is of high informativeness. It allows clinicians detecting early pre-nosological signs of oral microbiocenosis imbalance that enhances the effectiveness of early diagnosis of inflammatory periodontal diseases.

AbstractBackgroundThunb A.DC (Myrsinaceae), commonly known as “hen’s eyes”, has been traditionally used in treating various inflammatory diseases. The present study evaluated anti-arthritic, gastroprotective and antioxidant activities ofMethodsAnti-arthritic activity was evaluated in complete Freund adjuvant (CFA)-induced adjuvant arthritis and gastroprotective effect was studied in the ethanol-induced ulcer model in rats. ACRH was further isolated to yield quinone-rich fraction (QRF) and both were analyzed for their total phenolic content, total flavonoid content and antioxidant activities in various antioxidant assays. Both ACRH and QRF were also analyzed for the quinone composition via gas chromatography analysis.ResultsACRH exerted significant reduction of IL-1β and TNF-α at a lower dose range in CFA-induced arthritis, as well as exhibited its cytoprotective effect against ethanol-induced ulcer lesion via involvement of mucosal nonprotein sulfhydryl (NP-SH) groups. ACRH also showed higher phenolic and flavonoid contents, as well as better antioxidant activities than QRF.ConclusionsThese findings demonstrated the plant as a potential anti-inflammatory agent, with ACRH succeeded in inhibiting both arthritic and ulcerogenic effect, possibly mediated via its antioxidant effect.

The tumor necrosis factor-α (TNF-α) antagonists infliximab, adalimumab, and etanercept have been approved for the treatment of chronic inflammatory diseases such as rheumatoid arthritis, ankylosing spondylitis, psoriasis, and psoriatic arthritis. Manifestations of demyelinating disease have been reported for patients receiving TNF-α antagonists. We describe a rare manifestation of a chronic inflammatory process affecting both the central and peripheral nervous system in a patient who received infliximab for the treatment of psoriasis and psoriatic arthritis. Infliximab therapy was discontinued and symptoms improved under high-dose intravenous glucocorticoid pulse therapy.
