The main alterations of osteoarthritis are degenerative lesions of articular cartilage and secondary hyperostosis. Despite the unclear pathogenic mechanism, experimental studies have confirmed that the incidence of osteoarthritis is closely associated with inflammation-related substances. In this study, we explored the significance of serum GPX2 levels in patients with osteoarthritis and the mechanism of GPX2 in the anti-inflammation effects in osteoarthritis. As a result, serum GPX2 level was down-regulated and there was a negative correlation between GPX2 levels and IL-1β levels in patients with osteoarthritis. Over-expression of GPX2 decreased the inflammatory levels and down-regulation of GPX2 increased inflammatory levels in vitro. In contrast, GPX2 combined and regulated STAT3 protein expression. Over-expression of GPX2 promoted ubiquitination-STAT3 protein expression to decrease p-STAT3 protein expression in vitro. The inhibition of STAT3 attenuated the anti-inflammation effects of GPX2 in osteoarthritis. Thus, we proposed that GPX2 was down-regulated in patients with osteoarthritis and GPX2 played vital roles in osteoarthritis for clinical diagnosis or therapy.

Objectives The lung cancer is most frequently diagnosed cancer incidence worldwide. A large number of populations are heavily affected to this every year with poor prognosis. Methods Our study investigated the anticancer effect of alternariol, a secondary metabolite, on A549 lung cancer cell line and benzo-α-pyrene induced lung carcinoma model on balb/c mice. The cytotoxicity assay, DAPI staining and the flow cytometry was performed to assess the anticancer efficacy of alternariol in A549 lung cancer cell. For in vivo study the toxicity study was performed. The lung cancer was developed in the animals via intraperitoneal administration of benzo-α-pyrene and subsequently 2 weeks later alternariol treatment was carried out for 24 weeks. The chemotherapeutic effect of alternariol was assessed through histopathological analysis, followed by immunohistochemistry and in vivo antioxidant study. Results The in vitro data suggested a significant percentage of early and late apoptotic events in A549 cells with G0/G1 phase arrest which ultimately caused apoptosis followed by alternariol therapy. The in vivo study showed that alternariol therapy decreased the pulmonary fibrosis and formation of granuloma in lung tissue and restored the normal histopathological characteristics of lung. Furthermore, alternariol treatment downregulated the expression of PI3K, Akt and inflammatory mediators such as IL-6, TNF-α and increased the expression of apoptotic markers, p53. Conclusion In conclusion, the treatment with alternariol effectively decreased the progression of lung cancer through the inhibition of carcinogenic markers by reprogramming the p53/PI3K/Akt pathway and IL-6/TNF-α mediated cytokine signaling in mice.

Pancreatic cancer is one of the most lethal diseases around the world, for hardly detection and poor prognosis. Recent years, functions of the tumor microenvironment and immune cells attract people’s view and there is emerging evidence implicating some immune cells hold the key points in the metabolism, invasion, and metastasis in pancreatic cancer. In this review, we highlight some main immune cells, such as Tumor-associated neutrophils (TANs) and macrophages (TAMs), Pancreatic stellate cells (PSCs), Myeloid-derived suppressor cells (MDSCs), and Regulatory T cells (Tregs). Furthermore, we review current clinical applications and discuss potential values in future.

Objectives: Association of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and kidney injury has been noted in previous studies. However, the mechanisms remain unknown. The present study aimed to explore the potential mechanisms of kidney injury in COVID-19. Methods: Demographic characteristics, underlying diseases, signs, symptoms, and laboratory data of 100 COVID-19 patients were collected and analyzed in this retrospective study. Patients were divided into three groups: mild, moderate, and severe to critical group. Kidney injury was evaluated by markers including estimated glomerular filtration rate (eGFR), serum creatinine, blood urea nitrogen, and cystatin C. Results: A total of 100 patients with 12 mild, 63 moderate, and 25 severe to critical COVID-19 were included in this study. The kidney injury markers including eGFR, serum creatinine, blood urea nitrogen, and cystatin C all worsened significantly with an increase in disease severity. The correlation test showed that cytokines IL-2R, IL-6, IL-8, and tumor necrosis factor (TNF)-α were statistically correlated with eGFR and cystatin C. In multivariate analysis, log IL-6 (β = −0.331, p = .001 for eGFR and β = 0.405, p < .001 for cystatin C) and log TNF-α (β = −0.316, p = .001 for eGFR and β = 0.534, p < .001 for cystatin C) were found to be the major independent predictors of kidney injury. Conclusion: Serum IL-6 and TNF-α levels were the major independent predictors of kidney injury in COVID-19.

Morphea is a rare fibrosing disorder of the skin and underlying tissues. To date, the size of morphea has not been adequately discussed. Here, we report two cases of small-sized superficial circumscribed morphea. Both cases clinically revealed single circumscribed, round to oval area of shiny sclerotic plaque at distal extremities. There are several options for the treatment of superficial circumscribed morphea, such as topical corticosteroid and phototherapy. The early recognition of small-sized morphea enables appropriate diagnosis and follow-up, leading to improve disease prognosis.

Introduction Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by immune activation and multi-immunologic phenotypes. Interleukin-33 (IL-33) has been shown to be a critical and pleiotropic immunoregulatory mediator in the pathogenesis of many autoimmune diseases. At present, there are conflicting findings in the research of IL-33 in SLE. The purpose of this study was to investigate whether and how IL-33 is involved in the occurrence and development of SLE. Methods 43 SLE patients and 43 healthy volunteers were recruited for this study. Serum levels of IL-33, IL-4, IL-6, IL-10 and IL-21 were measured by ELISA. The expression of IL-33 was investigated in kidney sections by immunohistochemistry in lupus nephritis patients (n = 5) and controls (n = 3). The mRNA expressions of Toll like receptor 4 (TLR4), TLR2, and tumorigenicity 2 (ST2)L were quantified in peripheral blood mononuclear cells (PBMCs) by real-time PCR. The surface expression of TLR4 on T cells, B cells, monocytes, and neutrophils was assessed by flow cytometry (n = 22). Mann–Whitney U-test and Spearman’s test were used for statistical analysis. Results Serum concentrations of IL-33 were significantly higher in SLE patients than in healthy controls (p < 0.0001). IL-33 expressions were positively correlated with IL-4 and IL-6 levels in SLE patients, which play pivotal roles in the autoantibody production. In addition, TLR4 and TLR2 mRNA were markedly increased in PBMCs from SLE patients (p < 0.05). TLR4 was positively associated with IL-33, while TLR2 was not. Conclusions These results imply that upregulated expression of serum IL-33 together with increased TLR4 in PBMCs may contribute to the pathogenesis of SLE via promotion of inflammatory cytokines production.

To explore the relationship between IL-17 mediated immune response and HPV-negative cervical cancer, we established the co-culture system of cervical cancer C-33A cells and PBMC, and treated with different concentrations of rhIL-17. PBMC were extracted from 10ml anticoagulant blood provided by healthy female volunteers and colleagues in our hospital, which were co-cultured with cervical cancer C-33A cells. After treatment with different concentrations of rhIL-17, the proliferation, apoptosis, invasion behavior and VEGF expression level of cancer cells in each group, were determined by CCK-8, flow cytometry, transwell invasion assay and ELISA, respectively. The proliferation rate of C-33A cells slightly increased with the ascending of IL-17 concentration, but no statistical significance was found among each group (P > 0.05). When at low concentration of IL-17, the cell apoptosis rate seems to slightly decline. With the increase of concentration, the decrease of apoptosis rate became more obvious (P < 0.05). However, differing from those shown above, we found that IL-17 slightly inhibited the cancer cell invasion at high concentration, while it was more obvious at low concentration (P < 0.05). Furthermore, we found that there was no significant correlation between IL-17 and VEGF (P > 0.05). In summary, there is a close correlation between IL-17 mediated immune response and HPV-negative cervical cancer. Also, we think that IL-17 may play a dual role in tumor progression and could be a possible significant influence on tumor proliferation, apoptosis, and metastasis, which provides a basic theoretical basis for the further study of immunotherapy measures for cervical cancer.

Synovial tuberculosis in the wrist is a rare disease that is usually misdiagnosed at the early stage. In this case, we presented a 67-year-old male with wrist joint tuberculosis who presented repeated left wrist joint edema for more than 2 years. The patient received surgery twice. During the second surgery, the combination of metagenomic next-generation sequencing (mNGS) and pathological analysis contributed to the detection of Mycobacterium tuberculosis in lesion tissues. Conventional anti-tubercular therapy confirmed the diagnosis of synovial tuberculosis in the wrist joint. In conclusion, mNGS contributed to the rapid and accurate detection of tubercle bacillus.

Introduction: The effectiveness of programmed cell death protein 1 (PD-1) and programmed cell death ligand 1 (PD-L1) on tumor has been reported. However, the immune-related adverse events (irAEs) and its clinical management of the immune checkpoint inhibitors (ICIs) have not been fully understood. We aimed to analyze the irAEs and its ICIs targeting the PD-1/PD-L1. Methods: The retrospective analysis was performed on the irAEs of cancer patients treated with anti-PD1/PD-L1 monoclonal antibodies from January 2020 to August 2021 including 240 patients/547 cycles. The following aspects including the categories and the grades of the adverse events (AEs), the time of onset and duration, management plan, and prognosis were evaluated. Results: Among 240 patients, 93 patients (38.75%) experienced irAEs, and 10 patients (4.16%) had AEs that involved multiple organ systems at the same time. There were 83 cases (34.58%) of grade 1–2 AEs and 10 cases (4.17%) of grade three and above AEs. AEs above grade three included five cases of grade three AEs (3 cases of hepatic toxicity, one case of colitis, and one case of skin toxicity), three cases of grade four AEs (pneumonia); and 2 cases of grade five AEs (two deaths due to pneumonia). The complete remission of AEs was achieved in 10 patients by corticosteroid impulse therapy, maintenance therapy, and symptomatic therapy. Among them, six cases continued to use anti-PD1/PD-L1 monoclonal antibodies, two cases stopped, and two patients died from systemic multi-organ failure due to the delayed observation of autoimmune pneumonia. IrAEs occurred at different times and durations in different systems or organs. Conclusion: The safety of PD-1/PD-L1 inhibitors was approved in clinical applications. The prevalence of grade three and above AEs is relatively low. Timely diagnosis and early glucocorticoid therapies are adequate and effective approaches for the management of irAEs.

Timely diagnosis and early glucocorticoid therapies are adequate and effective approaches for the management of irAEs.","PeriodicalId":55162,"journal":{"name":"European Journal of Inflammation","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48647137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Diclofenac (DIC) is administrated to treat pain, inflammatory disorders, and dysmenorrhea but kidney problems are the main worries of the agent. The literature has revealed that quercetin (QR) has anti-inflammatory and antioxidant attributes. This study aims to highlight the possible nephroprotective effects of QR on DIC-exposed rats. In this study, the animals after exposure to DIC (50 mg/kg, i.p) were administrated to QR (100 mg/kg, p.o). Then, the levels, as well as the activity of several oxidant and anti-oxidant mediators, were evaluated. Our results showed that DIC treatment was coupled with the elevation in the levels of malondialdehyde (MDA), nitric oxide (NO), and some pro-inflammatory factors such as TNF-α, NF-κB, and IL-1β, suggesting that probably this agent exert its toxicity in the kidney tissue through inducing both oxidative stress and inflammation. Interestingly, QR was successful in restoring the activity of antioxidant compounds such as GSH, GPx, SOD, and CAT in the kidney tissue of DIC-treated rats. Moreover, in the presence of QR, DIC was unable to increase the expression of pro-inflammatory cytokines, suggesting that perhaps QR might have anti-inflammatory properties. In agreement with this, the results of the histopathological evaluation also showed that while DIC increased the lymphocyte infiltration into the kidney tissue, QR reduced the number of lymphocytes in DIC-treated rats. The results revealed that QR exerted a supportive effect against diclofenac-induced renal injury in male rats through modulation of oxidative stress and mitigation of inflammatory response.
