A Novel Chinese Medicine, Xinfeng Capsule, Modulates Proinflammatory Cytokines via Regulating the Toll-Like Receptor 4 (TLR4)/Mitogen-Activated Protein Kinase (MAPK)/Nuclear Kappa B (NF-κB) Signaling Pathway in an Adjuvant Arthritis Rat Model.

BACKGROUND Rheumatoid arthritis (RA) is a chronic autoimmune disease targeting joints. This research aimed to explore the effects of Xinfeng capsules (XFC) on cardiac injury in adjuvant arthritis (AA) model rats and assessed the associated mechanism. MATERIAL AND METHODS An adjuvant arthritis (AA) rat model was established by intracutaneously injection with Freund's complete adjuvant (FCA).

[Effect of Xinfeng Capsule on AS Patients and Their Serum Immunoglobulin Subtypes and Peripheral Lymphocyte Autophagy].

Objective: To observe the effect of Xinfeng Capsule (XFC) on ankylosing spondylitis (AS) patients' symptoms and signs, serum immunoglobulin levels, peripheral blood lymphocyte autophagy protein, autophagy gene, and to explore its mechanism.

Methods: Totally 59 AS patients were assigned to the treatment group (39 cases) and the control group (20 cases) according to random digit table. Patients in the treatment group received XFC, 0.

Xinfeng capsule for the treatment of rheumatoid arthritis patients with decreased pulmonary function--a randomized controlled clinical trial.

Objective: To determine the effectiveness and safety of Xinfeng Capsules (XFC) for the treatment of rheumatoid arthritis (RA) patients with decreased pulmonary function.

Methods: This was a randomized controlled clinical trial of 80 RA patients. Participants were assigned to the trial group (40 cases) and the control group (40 cases) by block randomization.

[Exploration of the mechanism of xinfeng capsule in the treatment of ankylosing spondylitis based on B and T lymphocyte attenuator and oxidative stress].

Objective: To explore changes of B and T lymphocyte attenuator (BTLA), superoxide dismutase (SOD), catalase (CAT), total antioxidant capacity (TAOC), reactive oxygen species (ROS), reactive nitrogen species (RNS), malondialdehyde (MDA) in ankylosing spondylitis (AS) patients, and the effect of Xinfeng Capsule (XFC) on them.

Methods: Totally 120 AS patients were assigned to two groups according to random digit table method, the XFC group (3 XFC pills each time, 3 times a day) and the SASP group (4 SASP tablets each time, twice a day), 60 in each group. All patients were treated for 3 months.

Effect of xinfeng capsule on the cardiac function in patients with rheumatoid arthritis.

Objective: To study the changes in cardiac function of rheumatoid arthritis (RA) patients and: to observe the effect of xinfeng capsule ( XFC) on them.

Methods: Sixty-eight RA patients were: randomly assigned to two groups by a lottery: 38 patients in the treatment group treated orally with XFC, 3 capsules, thrice a day, and 30 in the control group treated with fengshi gutong capsule (FSGTC), 4 capsules, twice a day, 30 days as one course of treatment, and two courses were given for both groups. A normal control (NC) group including 20 healthy subjects was set up.
