Sinomenine inhibits the inflammatory responses of human fibroblast-like synoviocytes the TLR4/MyD88/NF-κB signaling pathway in rheumatoid arthritis.

Rheumatoid arthritis (RA) is a systemic autoimmune disorder mainly characterized by inflammation of the synovial tissue that can lead to destruction of bone and cartilage. Sinomenine is an alkaloid extracted from the stem of the Chinese medicinal plant Sinomenium acutum. It has been reported that sinomenine has immunosuppressive and anti-inflammatory properties.

Curcumin inhibits osteoclastogenic potential in PBMCs from rheumatoid arthritis patients via the suppression of MAPK/RANK/c-Fos/NFATc1 signaling pathways.

The aim of the present study was to determine the effects of curcumin on the osteoclastogenic potential of peripheral blood mononuclear cells (PBMCs) obtained from patients with rheumatoid arthritis (RA), and to investigate the underlying molecular mechanisms. PBMCs from patients with RA (n=12) and healthy controls (n=10) were cultured to assess osteoclastogenic potential. The number of tartrate‑resistant acid phosphatase‑positive osteoclasts differentiated from PBMCs isolated from patients with RA was significantly increased compared with that of the healthy controls.

Synthesis and anti-BVDV activity of novel δ-sultones in vitro: implications for HCV therapies.

In this study we report the synthesis and activity against bovine viral diarrhea virus (BVDV) of a novel series of bicycle δ-sultones containing γ-lactones. BVDV is responsible for major losses in cattle. Some of the synthesized δ-sultones showed pronounced anti-BVDV activity with EC50 values of 0.

Sinomenine decreases MyD88 expression and improves inflammation-induced joint damage progression and symptoms in rat adjuvant-induced arthritis.

Sinomenine (SIN) is the active principle of the Chinese medical plant Sinomenium acutum which is widely used for the treatment of rheumatoid arthritis (RA) in China. Recently, several groups indicated that myeloid differentiation primary response protein 88 (MyD88) might be associated with disease progression of RA. Here, we observed the effect of SIN on MyD88 expression and showed its therapeutic role in RA.

A facile synthesis, antibacterial activity of pulvinone and its derivatives.

Pulvinone and several 3-fluoro-4-morpholino substituted pulvinone derivatives were synthesized in five steps from a common precursor, phenyl acetic acid. Most of synthetic morpholine substituted pulvinones showed inhibitory activity against Esherichia coli. For the first time, the inhibition of pulvinone and its derivatives against Gram-negative bacteria was reported.

[Effect of acupuncture on serum leptin level in patients with type II diabetes mellitus].

Objective: To study the relationship between serum leptin and insulin resistance, and to analyze the effect of acupuncture on serum leptin level in patients with type-II diabetes mellitus (DM).

Methods: A total of 80 type-II DM patients were randomized into acupuncture and medication groups. Acupuncture was applied to Yishu (EX), Feishu (BL13), Pishu (BL 20), etc.

[Relationship between lupus headache and headache due to internal injury in traditional Chinese medicine].

In 1999, the nomenclature and case definitions for neuropsychiatric lupus syndromes were published by American College of Rheumatology (ACR), and the cognition of neuropsychiatric damage of systemic lupus erythematosus (SLE) was gradually unified and standardized. Lupus headache is an intractable problem in SLE, especially in SLE patients complicated with multiple organ injury. In general, vascular headache is common in most SLE patients, and a small number of SLE patients complicated with nervous headache are found in clinic.
