One hundred and fifty patients with rheumatoid arthritis (RA) were treated with immunosuppressive drugs for 12 months. Fifty nine patients were treated with methotrexate (MTX), 15 with cyclophosphamide (CTX), 30 with prednisone (PRE) and 46 with non steroidal antiinflammatory drugs (NSAID). The cell surface phenotype of lymphocyte was analyzed using immunofluorescence methods ans a variety of monoclonal antibodies. The studies were performed using fluorescence activated cell scanner (FACScan) and epifluorescence microscope. No changes in the percentage of CD3, CD4, CD8 were observed. However, in the MTX treated group the percentage of CD19+ (15.1% before treatment vs 10.2% after 12 months MTX treatment (p < 0.05) and CD5+CD19+ B-cells was decreased. In CTX treated group the percentage of both B cells (17.4% vs 11.0% (p < 0.5)) and activated T cells was decreased (CD25+: 2.8% vs 1.1%, p < 0.05 and HLA-DR+: 22.1% vs 12.7%, p < 0.01). Patients treated with prednisone expressed several changes in lymphocyte phenotype i.e. decreasing of activated T cells (CD3+CD25+: 6.9% vs 3.6%, p < 0.01), B cells (CD5+CD19+: 3.4% vs 0.8%, p < 0.001), and NK cells (CD16+: 14.8% vs 8.5, p < 0.01 and CD56+: 16.3% vs 10.7%, p < 0.01). Analyzing immunosuppressive drugs appeared to be very sufficient in the RA treatment. Moreover, the correlation between percentage of both B lymphocytes and activated T cells, and activity of disease were shown.

Aim: The continuous update of international guidelines and enhanced availability of biological disease-modifying antirheumatic drugs (bDMARDs) and targeted synthetic DMARDs (tsDMARDs) have made a significant impact on the diagnosis and treatment of early rheumatoid arthritis (ERA). This study aims to systematically evaluate the current treatment strategies and outcomes within a large-scale cohort of patients with ERA.
Methods: Data from the Chinese Registry of Rheumatoid Arthritis (CREDIT), a large multicenter Chinese registry of RA, were collected to analyze temporal trends in clinical profiles, therapeutic strategies, and treatment outcomes among patients with ERA.
Formulation Factors Affecting the Formation of Visible-Bubbles During the Reconstitution Process of Freeze-Dried Etanercept Formulations: Protein Concentration, Stabilizers, and Surfactants.

Freeze drying is one of the common methods to extend the long-term stability of biologicals. Biological products in solid form have the advantages of convenient transportation and stable long-term storage. However, long reconstitution time and extensive visible bubbles are frequently generated during the reconstitution process for many freeze-dried protein formulations, which can potentially affect the management efficiency of staff, patient compliance, and product quality.

This study aims to synthesize a new localized drug delivery system of bioglass, polyvinyl alcohol (PVA), cellulose (CNC), and sodium alginate (SA) beads as a carrier for methotrexate (MTX) drugs for the treatment of osteosarcoma. Methotrexate /Bioglass-loaded Polyvinyl/Cellulose/Sodium alginate biocomposite beads were prepared via the dropwise method with different concentrations of (65%SiO-30%CaO- 5%PO) bioglass. Samples were named B0, S0, S1, S2, and S3, respectively.

Background: Systemic lupus erythematosus (SLE) is a complex and incurable autoimmune disease, so several drug remission for SLE symptoms have been developed and used at present. However, treatment varies by patient and disease activity, and existing medications for SLE were far from satisfactory. Novel drug targets to be found for SLE therapy are still needed.
