The purpose of this study was to investigate the effects of salvianolic acid A (SAA) in systemic lupus erythematosus (SLE) induced by pristane in BALB/c mice. Lupus mice were established by confirming elevated levels of autoantibodies and IL-6 after intraperitoneal injection of pristane. Mice were then treated with daily oral doses of SAA for 5 months in parallel with mice treated with prednisone and aspirin as positive controls. The levels of autoantibodies were monitored at monthly intervals and nephritic symptoms observed by hematoxylin and eosin (H&E) and periodic acid-Schiff (PAS) staining...

The aim of the present study was to determine whether thoracic spinal manipulation (SM) decreases temporal summation of back pain. The study comprised 2 controlled experiments including 16 and 15 healthy participants, respectively. Each study included 6 sessions during which painful or non-painful electrical stimulations were delivered in three conditions: 1) control 2) light mechanical stimulus (MS) or 3) SM. Electrical stimulation was applied on the thoracic spine (T4), in the area where SM and MS were performed...

Genetic deficiency in TLR9 accelerates pathogenesis in the spontaneous polygenic MRL.Faslpr murine model of systemic lupus erythematosus, despite the absence of anti-nucleosome autoantibodies. However, it could be argued that this result was dependent on Fas-deficiency rather than lupus-promoting genes in the MRL genetic background. Here we report the effects of TLR9 deficiency on autoimmune disease independent of the lpr mutation in Fas by characterizing Tlr9-/- and Tlr9+/+ mice on the Fas-intact MRL/+ genetic background...

Five previously undescribed hemiterpene glycosides, cibotiumbarosides E-I, and two known hemiterpene glucosides, were isolated from the rhizome of Cibotium barometz (L.) J. Sm. The structures of cibotiumbarosides E-I were established by 1D and 2D NMR spectroscopic analyses and HRMS. The absolute configuration of the aglycone of cibotiumbaroside E was assigned by calculated ECD with the TDDFT method. Cibotiumbarosides F and I both exhibited remarkable hepatoprotective activity against APAP-induced acute liver damage in vitro, which were more effective than the positive control, bicyclol...

OBJECTIVES: It is well-known that lymphocytes play an important role in systemic lupus erythematosus (SLE). T cell immunoreceptor with Ig and immunoreceptor tyrosine-based inhibitory domains (TIGIT) is one of immunosuppressive costimulatory molecules that mediates an inhibitory effect. However, its roles in SLE are poorly understood. This study was designed to investigate the correlation between the frequencies of TIGIT-expressing CD3(+)CD4(+) T lymphocytes and SLE. METHODS: Patients with SLE were recruited from the First Affiliated Hospital of Nanchang University...

OBJECTIVES: Mixed connective tissue disease (MCTD) is characterized by the presence of anti-U1-snRNP autoantibodies and a variable set of associated clinical features. Some MCTD patients test positive over time to autoantibodies against Sm, proteins spatially related with U1-snRNP. This situation has been attributed to expanding of the autoimmune response by a phenomenon known as epitope spreading. Our aim was to study the frequency of this phenomenon in MCTD patients and the specific clinical features of those with epitope spreading...

BACKGROUND/OBJECTIVES: Delayed treatment failure occurs in a significant proportion of inflammatory bowel disease (IBD) patients treated with tumor necrosis factor-alpha (TNF) antagonists. Identification of predictors of loss of response (LOR) may help to optimize therapy. We sought to determine whether body composition parameters at the commencement of anti-TNF therapy were associated with earlier treatment failure. SUBJECTS/METHODS: A retrospective cohort study was performed on 68 patients who had undergone cross-sectional abdominal imaging coincident with the commencement of anti-TNF drugs...

Silymarin (SM), and its flavonolignan components, alter cellular metabolism and inhibit inflammatory status in human liver and T cell lines. In this study, we hypothesized that SM suppresses both acute and chronic immune activation (CIA), including in the context of HIV infection. SM treatment suppressed the expression of T cell activation and exhaustion markers on CD4+ and CD8+ T cells from chronically-infected, HIV-positive subjects. SM also showed a trend towards modifying CD4+ T cell memory subsets from HIV+ subjects...

Silymarin (SM) is a well-known antioxidant, anti-inflammatory and anti-cancer compound extracted from the milk thistle. Here, we investigated the protective effect of SM against acrylamide (AA)-induced neurotoxicity, mainly caused by oxidative stress, via activation of the nuclear transcription factor E2-related factor 2 (Nrf2) signalling pathway in PC12 cells. The MTT reduction assay was used to measure cell viability in various drug-treated groups and demonstrated that SM could increase cell viability in AA-treated PC12 cells...

Nearly all genetic crosses generated from Apoe(-/-) or Lldlr(-/-) mice for genetic analysis of atherosclerosis have used C57BL/6 J (B6) mice as one parental strain, thus limiting their mapping power and coverage of allelic diversity. SM/J-Apoe (-/-) and BALB/cJ-Apoe (-/-) mice differ significantly in atherosclerosis susceptibility. 224 male F2 mice were generated from the two Apoe (-/-) strains to perform quantitative trait locus (QTL) analysis of atherosclerosis. F2 mice were fed 5 weeks of Western diet and analyzed for atherosclerotic lesions in the aortic root...

Synergies between sulfonamides and other antimicrobial agents have long been reported, but the reason still remains unclear. Previously, Vilchèze et al. found that, sulfamethoxazole (SMX) could potentiate the bacterialcidal activity of isoniazid (INH) and rifampin (RIF) in Mycobacterium tuberculosis. To test if this was also the case in other bacteria, the ability to potentiate bactericidal effect of RIF by SMX was evaluated in Escherichia coli, Staphylococcus aureus, Salmonella typhimurium and Mycobacterium smegmatis...

A lack of knowledge about mental health and stigma of the mentally ill are barriers to the treatment of mental disorders. To reduce these barriers, anti-stigma campaigns using a knowledge contact approach were launched to raise public mental health knowledge by education and to reduce stigma by encouraging contact with individuals with mental disorders. The current study attempted to investigate the outcome of a knowledge contact-based programme in adolescents and adults in the Hong Kong Chinese population...
