  • Activation of the NLRP3 inflammasome is critical for host defense as well as the progression of inflammatory diseases through the production of the proinflammatory cytokine IL-1β, which is cleaved by active caspase-1. It has been reported that overactivation of the NLRP3 inflammasome contributes to the development and pathology of acne vulgaris. Therefore, inhibiting activation of the NLRP3 inflammasome may provide a new therapeutic strategy for acne vulgaris. In this study, we investigated whether auranofin, an anti-rheumatoid arthritis agent, inhibited NLRP3 inflammasome activation, thereby effectively treating acne vulgaris. Auranofin suppressed NLRP3 inflammasome activation induced by Propionibacterium acnes, reducing the production of IL-1β in primary mouse macrophages and human sebocytes. In a P. acnes-induced acne mouse model, injection of P. acnes into the ears of mice induced acne symptoms such as redness, swelling, and neutrophil infiltration. Topical application of auranofin (0.5 or 1%) to mouse ears significantly reduced the inflammatory symptoms of acne vulgaris induced by P. acnes injection. Topical application of auranofin led to the downregulation of the NLRP3 inflammasome activated by P. acnes in mouse ear skin. These results show that auranofin inhibits the NLRP3 inflammasome, the activation of which is associated with acne symptoms. The results further suggest that topical application of auranofin could be a new therapeutic strategy for treating acne vulgaris by targeting the NLRP3 inflammasome.

  • Objective: Tumor necrosis factor-alpha (TNF-alpha) inhibitors are used as a treatment in various immune-mediated inflammatory diseases (IMIDs). Tuberculosis (TB) risk is reported in several meta-analyses in patients treated with TNF-alpha inhibitors. The purpose of this study is to collect, review, and evaluate the TB risk in TNF-alpha inhibitors according to IMIDs indications and between soluble-receptor TNF-alpha inhibitor and monoclonal-antibody TNF-alpha inhibitors. Methods: A systematic literature search on systematic reviews and meta-analyses was performed in PubMed, MEDLINE, Cochrane library, and EMBASE. We identified meta-analyses that evaluated TB infection risk of TNF-alpha inhibitors in IMIDs patients. Results: Thirteen meta-analyses including 41 study results were included in this umbrella review. IMIDs patients treated with TNF-alpha inhibitors had an increased risk of TB than control group (placebo with or without standard therapy patients) (relative risk ratio (RR) 2.057, 95% confidence interval (CI) 1.697 to 2.495). Among them, RA patients with TNF-alpha inhibitors had a higher risk of TB than control group (RR 1.847, 95% CI 1.385 to 2.464), and non-RA patients with TNF-alpha inhibitors had an increased risk of TB (RR 2.236, 95% CI 1.284 to 3.894). In subgroup analysis on TB risk between soluble-receptor TNF-alpha inhibitor and monoclonal-antibody TNF-alpha inhibitors in RA patients, the analysis indicated that monoclonal-antibody TNF-alpha inhibitors had higher risk of TB than soluble-receptor TNF-alpha inhibitor (RR 2.880, 95% CI 1.730 to 4.792). Conclusion: This umbrella review confirms that the risk of TB is significantly increased in TNF-alpha inhibitor treated patients compared to control group.

  • Objectives : This study was conducted to investigate the effect of HT008, a multi-herbal mixture consisting of 3 herbs, Eleutherococcus senticosus, Angelica sinensis, and Scutellaria baicaleinsis on arthritic model in rats. Methods : The anti-inflammatory and analgesic activities were observed by utilizing the following models: carrageenan-induced edema of the hind paw of rats, acetic acid-induced writhing response in mice. The perimeter of the paw was measured before injection and then at 1, 2, 4, 6 h after injection of 1% $\lambda$-carrageenan. The HT008 at five dose levels (10, 30, 100, and 300 mg/kg) and distilled water given 30 min to treatment groups and control group, before $\lambda$-carrageenan injection. In the writhing test, the mice received 0.7% acetic acid solution in normal saline injected intraperitoneally at a dose of 10 ml/kg. The number of writhes was counted staring 10 min after injection. Results : HT008 at four dose levels (30, 100, and 300 mg/kg) significantly decreased the carrageenan-induced rat paw edema perimeter. E. senticosus and S. baicaleinsis extracts reduced acetic acid-induced writhing response in mice. Also A. sinensis extracts significantly decreased the carrageenan-induced rat paw edema perimeter. Conclusions : These results show that HT008, a multi-herbal mixture has both anti-inflammatory activity and analgesic effects in vivo arthritic model, and suggest that HT008 could be a good therapy to treat human osteoarthritis.

  • Background: Ellipticine (Ellip.) was recently reported to have beneficial effects on the differentiation of adipose-derived stem cells into mature chondrocyte-like cells. On the other hand, no practical results have been derived from the transplantation of bone marrow stem cells (BMSCs) in a rabbit osteoarthritis (OA) model. Objectives: This study examined whether autologous BMSCs incubated with ellipticine (Ellip.+BMSCs) could regenerate articular cartilage in rabbit OA, a model similar to degenerative arthritis in human beings. Methods: A portion of rabbit articular cartilage was surgically removed, and Ellip.+BMSCs were transplanted into the lesion area. After two and four weeks of treatment, the serum levels of proinflammatory cytokines, i.e., tumor necrosis factor α (TNF-α) and prostaglandin E2 (PGE2), were analyzed, while macroscopic and micro-computed tomography (CT) evaluations were conducted to determine the intensity of cartilage degeneration. Furthermore, immuno-blotting was performed to evaluate the mitogen-activated protein kinases, PI3K/Akt, and nuclear factor-κB (NF-κB) signaling in rabbit OA models. Histological staining was used to confirm the change in the pattern of collagen and proteoglycan in the articular cartilage matrix. Results: The transplantation of Ellip.+BMSCs elicited a chondroprotective effect by reducing the inflammatory factors (TNF-α, PGE2) in a time-dependent manner. Macroscopic observations, micro-CT, and histological staining revealed articular cartilage regeneration with the downregulation of matrix-metallo proteinases (MMPs), preventing articular cartilage degradation. Furthermore, histological observations confirmed a significant boost in the production of chondrocytes, collagen, and proteoglycan compared to the control group. Western blotting data revealed the downregulation of the p38, PI3K-Akt, and NF-κB inflammatory pathways to attenuate inflammation. Conclusions: The transplantation of Ellip.+BMSCs normalized the OA condition by boosting the recovery of degenerated articular cartilage and inhibiting the catabolic signaling pathway.

  • Peroxisome proliferator-activated receptor gamma ($PPAR{\gamma}$) was identified as a cell-intrinsic regulator of Th17 cell differentiation. Th17 cells have been associated with several autoimmune diseases, including experimental autoimmune encephalomyelitis (EAE), inflammatory bowel disease (IBD), and collagen-induced arthritis. In this study, we confirmed $PPAR{\gamma}$-mediated inhibition of Th17 cell differentiation and cytokine production at an early stage. Treatment with ciglitazone, a $PPAR{\gamma}$ ligand, reduced both IL-$1{\beta}$-mediated enhancement of Th17 differentiation and activation of Th17 cells after polarization. For Th17 cell differentiation, we found that ciglitazone-treated cells had a relatively low proliferative activity and produced a lower amount of cytokines, regardless of the presence of IL-$1{\beta}$. The inhibitory activity of ciglitazone might be due to decrease of CCNB1 expression, which regulates the cell cycle in T cells. Hence, we postulate that a pharmaceutical $PPAR{\gamma}$ activator might be a potent candidate for treatment of Th17-mediated autoimmune disease patients.

  • Background: Monocyte chemoattractant protein-1 (MCP-1) is a major chemokine thought to be responsible for monocyte and T-lymphocyte recruitment in acute inflammatory conditions and recruitment of macrophages in tumors. It is also implicated in cardiovascular disease, rheumatoid arthritis and chronic obstructive pulmonary disease. The aim of the present study was to investigate the correlation between MCP-1 -2518 A/G polymorphism and breast cancer risk in patients from Amritsar city of Punjab state in North-West India. Materials and Methods: We screened DNA samples of 200 sporadic breast cancer patients and 200 age and gender matched unrelated healthy individuals for MCP-1 -2518 A/G polymorphism using the PCR-RFLP method. Results: A significantly increased frequency of the GG genotype was observed in patients as compared to controls. Individuals carrying the MCP1 -2518GG genotype had a two fold risk for breast cancer (OR=2.06, 95%CI, 1.06-3.98; p=0.03). Genetic models analysis revealed a significant association between MCP-1 -2518 A/G polymorphism and cancer risk in homozygous co-dominant (OR=2.06, 95%CI, 1.06-3.98; p=0.03) and recessive (OR=1.97, 95%CI, 1.05-3.70; p=0.03) models. Conclusions: We conclude that the GG genotype of the MCP-1-2518 A/G polymorphism is associated with increased risk to breast cancer in Punjab, North-West India.

  • Objectives: The purpose of this study was to investigate the current trends in research on pharmacopuncture in Korea since 2007. Methods: A literature review was performed by using the search engines 'Science and Technology Society Village', 'Korean Studies Information Service System', 'National Discovery for Science Leaders', and 'Oriental Medicine Advanced Searching Integrated System' in Korea from January 2007 to December 2013. Searched key words were 'pharmacopuncture', 'herbal acupuncture', 'aqua-acupuncture', and 'bee venom'. Finally, we selected 457 papers, including Korean experimental studies and clinical studies. Selected papers were classified according to year of publication, type of pharmacopuncture, disease & topic, research type and the publishing journal. Results: One hundred fifty pharmacopunctures were studied in 457 papers. Single compound pharmacopuncture was the most studied pharmacopuncture in experimental studies while animal-based pharmacopuncture was the most studied pharmacopuncture in clinical studies. Bee venom placed first among the various pharmacopunctures, followed by placenta, sweet bee venom, mountain-ginseng, and anti-inflammatory pharmacopunctures. Experimental research on pharmacopuncture has fallen since 2007 when 55 papers were published. However, clinical research has been increasing steadily. In clinical studies, case reports were numerous than randomized clinical trials (RCTs). Musculoskeletal diseases were the most frequently-treated diseases in studies on pharmacopuncture; among the musculoskeletal diseases, rheumatoid arthritis was the most frequently-treated disease in experimental studies and low back pain was the most frequently-treated condition in clinical studies. Since 2007, 45 different journals have published studies on pharmacopuncture, with the Journal of the Korean Acupuncture and Moxibustion Medicine Society having the largest number of papers on pharmacopuncture and the Journal of Pharmacopuncture the second largest number. Conclusion: The trends in research on pharmacopuncture published in studies from 2007 to 2013 were similar to those in studies published before 2006. Many studies on pharmacopuncture focused on bee venom and musculoskeletal diseases. Additional studies on diverse types of and indications for pharmacopuncture are needed.

  • Osteoblasts are affected by TNF-${\alpha}$ overproduction by immune cells during inflammation. It has been suggested that functional $NF-{\kappa}B$ sites are involved in TNF-${\alpha}$-induced bone resorption. Thus, we explored the effect of pyrrolidine dithiocarbamate (PDTC), which potently blocks the activation of nuclear factor $(NF-{\kappa}B)$, on the induction of TNF-${\alpha}$-induced activation of JNK/SAPK, AP-1, cytochrome c, caspase and apoptosis in MC3T3E1 osteoblasts. Pretreatment of the cells with PDTC blocked TNF-${\alpha}$-induced $NF-{\kappa}B$ activation. TNF-${\alpha}$-induced activation of AP-1, another nuclear transcription factor, was suppressed by PDTC. The activation of c-Jun N-terminal kinase, implicated in the regulation of AP-1, was also down regulated by PDTC. TNF-${\alpha}$-induced apoptosis, release of cytochrome c and subsequent activation of caspase-3 were abolished by PDTC. TNF-${\alpha}$-induced apoptosis was partially blocked by Ac-DEVD-CHO, a caspase-3 inhibitor, suggesting that caspase-3 is involved in TNF-${\alpha}$-mediated signaling through $NF-{\kappa}B$ in MC3T3E1 osteoblasts. Thus, these results demonstrate that PDTC, has an inhibitory effect on TNF-${\alpha}$-mediated activation of JNK/SAPK, AP-1, cytochrome c release and subsequent caspase-3, leading to the inhibition of apoptosis. Our study may contribute to the treatment of TNF-${\alpha}$-associated immune and inflammatory diseases such as rheumatoid arthritis and periodontal diseases.

  • Chronic otitis media (COM) is a chronic inflammatory disease which affects the middle ear, mastoid cavity. It presents hearing loss, ear pain, dizziness, headache, temporomandibular joint (TMJ) inflammation and intracranial complication. Intracranial complications such as skull base osteomyelitis (SBO) may occur secondary to COM due to transmission of infection by a number of possible routes. SBO is an uncommon condition with a significant morbidity and mortality if not treated in the early stages. We report a-67-year-old male patient with diabetes and untreated COM who presented atypical severe TMJ, periorbital and postmandibular pain. By computerized tomography (CT), magnetic resonance imaging (MRI) and whole body bone scan (WBBS), he was diagnosed with SBO spreading from untreated COM via infective arthritis of TMJ. Through this case, we suggest proper utilization of diagnostic imaging, especially CT or MRI for the early detection of SBO in the case of COM accompanying with the greater risk of infection developments such as diabetes.
