The Activation of Muscarinic Acetylcholine Receptors Protects against Neuroinflammation in a Mouse Model through Attenuating Microglial Inflammation.

Neuroinflammation is a critical factor that contributes to neurological impairment and is closely associated with the onset and progression of neurodegenerative diseases. In the central nervous system (CNS), microglia play a pivotal role in the regulation of inflammation through various signaling pathways. Therefore, mitigating microglial inflammation is considered a promising strategy for restraining neuroinflammation.

Association of inflammatory trajectory with subarachnoid hemorrhage mortality.

Objective: White blood cells (WBC) play an important role in the inflammatory response of the body. Elevated WBC counts on admission in patients with subarachnoid hemorrhage (SAH) correlate with a poor prognosis. However, the role of longitudinal WBC trajectories based on repeated WBC measurements during hospitalization remains unclear.

Increased risk of malignancy in HLA-B27-positive patients with ankylosing spondylitis requiring biologics for sustained inflammation: A long-term, single-center retrospective study.

Objectives: To assess the link between the administration of biologic disease-modifying antirheumatic drugs (bDMARDs) and the risk of malignancy in human leukocyte antigen B27 (HLA-B27)-positive patients with ankylosing spondylitis (AS) experiencing sustained inflammation.

Methods: Between 2006 and 2021, 1445 HLA-B27-positive patients with AS were retrospectively evaluated. Among them, 112 patients required bDMARD therapy.

Hydroxychloroquine exacerbates imiquimod-induced psoriasis-like dermatitis through stimulating overexpression of IL-6 in keratinocytes.

Objective: Hydroxychloroquine (HCQ) is a US Food and Drug Administration (FDA)-approved treatment for systemic lupus erythematosus (SLE) through inhibition of antigen presentation and subsequent reduction in T cell activation. Psoriasis relapse after antimalarial therapy have been reported in up to 18% of patients with psoriasis. Here, we explored the role of HCQ on exacerbating dermatitis utilizing an imiquimod (IMQ)-induced psoriasis-like dermatitis mouse model.

Inhibition of NLRP3 Inflammasome Activation by 3H-1,2-Dithiole-3-Thione: A Potential Therapeutic Approach for Psoriasis Treatment.

Psoriasis is a chronic autoimmune skin disease with a significant impact on quality of life and potential for severe comorbidities. Inflammation in the skin is induced by immune cells that overexpress pro-inflammatory cytokines, with the Th17 cell playing a crucial role. NLRP3 inflammasome activation is associated with inflammatory diseases and abnormal T cell differentiation.

Brevilin A Ameliorates Imiquimod-Induced Psoriasis-like Dermatitis and Reduces Th17 Differentiation in Psoriasis Patients.

Psoriasis is a predominantly Th17 cell-driven chronic autoinflammatory skin disorder. Brevilin A, a natural sesquiterpene lactone extracted from , has been used as a traditional oriental medicine for allergic diseases for centuries. However, the effects of brevilin A on psoriasis have yet to be established.

Plasma anion gap and risk of in-hospital mortality in patients with spontaneous subarachnoid hemorrhage.

Background: The association between the serum anion gap (AG) and prognosis of patients with spontaneous subarachnoid hemorrhage (SAH) remains unknown. Thus, this study aimed to explore the association between AG levels and mortality in patients with SAH in the intensive care unit (ICU).

Methods: This was a retrospective analysis of data stored in the Medical Information Mart for Intensive Care-IV and eICU Collaborative Research databases.

Multifunctional Anti-Alzheimer's Disease Effects of Natural Xanthone Derivatives: A Primary Structure-Activity Evaluation.

A series of α-Mangostin (α-M) derivatives were designed and synthesized. α-M and four analogues were evaluated for their multifunctional anti-Alzheimer's disease (anti-AD) effects on fibrillogenesis, microglial uptake, microglial degradation, and anti-neurotoxicity of Aβ, as well as LPS-induced neuroinflammation. The differences in bioactivities were analyzed to understand the structure-activity relationship for further modifications.

Tenacissoside G synergistically potentiates inhibitory effects of 5-fluorouracil to human colorectal cancer.

Background: Colorectal cancer (CRC) is one of the most malignant tumors worldwide with poor prognosis and low survival rate. Since the clinical efficacy of the commonly used 5-fluorouracil (5-FU) based chemotherapy in CRC patients is limited because of its intolerable adverse effects, there is an urgent need to explore agents that can enhance the anti-cancer activity of 5-FU, reduce adverse effects and prevent resistance.

Purpose: This study aims to investigate Tenacissoside G (TG)'s synergistic potentiation with 5-FU in inhibitory activity to colorectal cancer cells.

Using percutaneous parapedicle screw vertebroplasty to treat transpedicle screw loosening.

Background: Pedicle screw loosening (PSL) is a postsurgical complication of spinal fusion surgery that can result in morbidity. The aim of this study was to evaluate the efficacy and safety of percutaneous parapedicle screw vertebroplasty (PPSV) for pain reduction and motility improvement in patients with PSL.

Methods: The postsurgical solid inter-body fusion with inter-body bone mass formation of 32 patients who underwent lumbar-sacrum spinal fusion surgery was confirmed with plain films and CT scans.

Real-world effectiveness and safety of rituximab in the treatment of rheumatoid arthritis: A single-center experience in Taiwan.

Aim: To assess the real-world effectiveness and safety of rituximab (RTX) at 24 months in patients with established rheumatoid arthritis (RA) and to identify predictors of low disease activity/remission and a good European League Against Rheumatism (EULAR) response.

Methods: Seventy RTX-treated RA patients were enrolled. Predictors for low disease activity/remission and a good EULAR response at 24 months were identified by multivariate analyses.

IgG4-related disease coexisting with autoimmune haemolytic anaemia.

An 85-year-old man presented with a pale appearance and generalised pruritic papules. Laboratory investigations disclosed eosinophilia, autoimmune haemolytic anaemia, mixed hyperbilirubinaemia, cholestasis and elevated serum IgG4 levels. Abdominal sonography and CT showed progressive dilatation of biliary trees, with diffuse pancreatic enlargement and a subtle capsule-like low-density rim around the pancreatic head and body.
