[Wangbi Tablets reduce inflammation in rat model of collagen-induced arthritis with syndrome of kidney deficiency by regulating cGAS-STING signaling pathway].

This study aims to investigate the therapeutic effect of Wangbi Tablets(WBT) on the inflammation in the rat model of collagen-induced arthritis(CIA) with the syndrome of kidney deficiency based on the cyclic guanosine monophosphate-adenosine monophosphate synthase(cGAS)-stimulator of interferon genes(STING) signaling pathway. Eighteen rats were randomly chosen from 24 SPF-grade rats for the modeling of CIA with the syndrome of kidney deficiency. The 24 SPF-grade rats were randomized into 4 groups: control(normal rats), model(CIA with syndrome of kidney deficiency), model+WBT(M+WBT), and model+methotrexate(M+MTX).

Hierarchically spherical assembly of carbon nanorods derived from metal-organic framework as solid-phase microextraction coating for nitrated polycyclic aromatic hydrocarbon analysis.

Nitrated polycyclic aromatic hydrocarbons (nitro-PAHs) are pervasive contaminants in aquatic environments. They are characterized by persistence, toxicity, bioaccumulation, and long-range transport, significantly threatening human health. The development of sensitive methods for nitro-PAH analysis in environmental samples is in great need.

Methylation of T and B Lymphocytes in Autoimmune Rheumatic Diseases.

The role of abnormal epigenetic modifications, particularly DNA methylation, in the pathogenesis of autoimmune rheumatic diseases (ARDs) has garnered increasing attention. Lymphocyte dysfunction is a significant contributor to the pathogenesis of ARDs. Methylation is crucial for maintaining normal immune system function, and aberrant methylation can hinder lymphocyte differentiation, resulting in functional abnormalities that disrupt immune tolerance, leading to the excessive expression of inflammatory cytokines, thereby exacerbating the onset and progression of ARDs.

Chemokines and lymphocyte homing in Sjögren's syndrome.

Sjögren's syndrome (SS) is a chronic systemic autoimmune disease that typically presents with lymphocyte, dendritic cell, and macrophage infiltration of exocrine gland ducts and the formation of ectopic germinal centers. The interactions of lymphocyte homing receptors and addressins and chemokines and their receptors, such as α4β7/MAdCAM-1, LFA-1/ICAM-1, CXCL13/CXCR5, CCL25/CCR9, CX3CL1/CX3CR1, play important roles in the migration of inflammatory cells to the focal glands and the promotion of ectopic germinal center formation in SS. A variety of molecules have been shown to be involved in lymphocyte homing, including tumor necrosis factor-α, interferon (IFN)-α, IFN-β, and B cell activating factor.

Efficacy and safety of the modified Zhiwang decoction combined with methotrexate in early rheumatoid arthritis: study protocol for a randomised controlled trial.

Introduction: Rheumatoid arthritis (RA) is a progressive inflammatory autoimmune disease characterised by chronic systemic inflammation, which can cause swelling, stiffening and destruction of articular cartilage and bone. Early diagnosis and treatment of RA can improve outcomes and slow the progression of joint damage. Preliminary exploratory research had hinted an expected effect of modified Zhiwang decoction (MZWD) in treating early RA.

Jolkinolide B ameliorates rheumatoid arthritis by regulating the JAK2/STAT3 signaling pathway.

Background: Jolkinolide B (JB), an ent‑abietane-type diterpenoid in Euphorbia plants, has various pharmacological activities, including anticancer, anti-inflammatory, and anti-tuberculosis activities. However, no previous studies have proven whether JB can be regarded as a targeted drug for the treatment of rheumatoid arthritis (RA).

Purpose: This study aimed to evaluate the anti-RA effects of JB and explore the potential mechanisms.

Interaction effects of significant risk factors on low bone mineral density in ankylosing spondylitis.

Background: To analyze individually and interactively critical risk factors, which are closely related to low bone mineral density (BMD) in patient with ankylosing spondylitis (AS).

Methods: A total of 249 AS patients who visited China-Japan Friendship Hospital were included in this training set. Patients with questionnaire data, blood samples, X-rays, and BMD were collected.

A bibliometric analysis of primary Sjögren's syndrome-associated lymphoma from 1991 to 2022.

Background: Patients with primary Sjögren's syndrome (pSS) take a higher risk of developing lymphoma, which is the most frequent cause of death in pSS. Based on this situation, the number of publications focusing on pSS-associated lymphoma has been growing. Nevertheless, the extent, range, and nature of available research in this field have not been systematically summarized.

Eosinophilic fasciitis difficult to differentiate from scleroderma: A case report.

Background: Eosinophilic fasciitis (EF) is a rare connective tissue disease that can cause swelling and sclerosis of the extremities, and special attention is needed to differentiate EF from systemic sclerosis. Misdiagnosis or omission markedly delays treatment of EF, and severe skin sclerosis in advanced stages can cause joint contracture and tendon retraction, worsening the patient's prognosis and quality of life.

Case Summary: We report a case of EF in a young woman diagnosed by tissue biopsy, confirming the difficulty of differential diagnosis with scleroderma.

Clinical characteristics, including disease manifestations and serological parameters of the disease, were compared between men and women with pSS using the Mann-Whitney U test and χ 2 test.

Role and mechanism of fibroblast-activated protein-α expression on the surface of fibroblast-like synoviocytes in rheumatoid arthritis.

Fibroblast-activated protein-α (FAP) is a type II integrated serine protease expressed by activated fibroblasts during fibrosis or inflammation. Fibroblast-like synoviocytes (FLSs) in rheumatoid arthritis (RA) synovial sites abundantly and stably overexpress FAP and play important roles in regulating the cellular immune, inflammatory, invasion, migration, proliferation, and angiogenesis responses in the synovial region. Overexpression of FAP is regulated by the initial inflammatory microenvironment of the disease and epigenetic signaling, which promotes RA development by regulating FLSs or affecting the signaling cross-linking FLSs with other cells at the local synovium and inflammatory stimulation.

Knowledge mapping of autophagy in osteoarthritis from 2004 to 2022: A bibliometric analysis.

Background: Autophagy in osteoarthritis (OA) has become an active area of research with substantial value and potential.

The main goal of this study was to map the available literature on the role of autophagy in OA and identify global research hotspots and trends.

Wangbi granule as a combination therapy to achieve clinical deep remission in rheumatoid arthritis: protocol for a multicenter, triple-blind, randomised, placebo-controlled trial.

Introduction: Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease that may lead to bone erosion and disability. Although there are many biological therapies in RA treatment nowadays, such as etanercept and tofacitinib, there are still a considerable number of patients who cannot achieve clinical deep remission, which makes patients feel pain and stiffness of joints. As a traditional Chinese medicine preparation, Wangbi granule showed a synergistic role with methotrexate in the treatment of RA patients with "kidney deficiency and dampness" or "stasis blocking channels".
