Abstract	Qingkailing (QKL) and Shuanghuanglian (SHHL) are two commonly used Chinese herbal preparations with reported antiinflammatory activity. The effects of these two preparations on the capacity of staphylococcal toxic shock syndrome toxin 1 (TSST-1) to stimulate the production of cytokines (IL-1beta, IL-6, TNF-alpha, IFN-gamma) and chemokines (MIP-1alpha, MIP-1beta and MCP-1) by peripheral blood mononuclear cell (PBMC) was tested. We also evaluated their effect on LPS-stimulated NF-kappaB transcriptional activity in a THP-1 cell line, and on human monocyte chemotactic response to chemoattractants. Non-cytotoxic concentrations of QKL (0.1similar to2%) and SHHL (6similar to120 mug) significantly inhibited production of cytokines and chemokines in a dose-dependent manner (P < 0.05). Both, QKL at 1:100 and SHHL at 60 mug/ml, markedly inhibited RANTES, MIP-1alpha, SDF-1alpha and fmLP induced human monocyte migration (P < 0.05 or 0.01). QKL (1%) did not inhibit monocyte chemotaxis induced by super-or sub-optimal concentrations of fMLP (10(-5), 10(-6) and 10(-10) M), but only inhibited chemotaxis induced by optimal concentrations of fMLP at 10(-7), 10(-8) and 10(-9) M. QKL (0.1% or 1%) and SHHL(6 or 60 mug/ml) markedly inhibited LPS-induced NF-kappaB activity in THP-1 cells. The results suggested that the pharmacological basis for the antiinflammatory effects of QKL and SHHL is the result of suppression of NF-kappaB regulated gene transcription, leading to suppressed production of proinflammatory cytokine and chemokine. Interference with leukocyte chemotaxis also contributes to the anti inflammatory and immunomodulating effects of these medicinals. Identification of the responsible components in these two herbal preparations may yield compounds suitable for structural modification into potent novel drugs.
