Effects of warming-needle therapy on gene expression pathways in the patient with knee osteoarthritis of deficiency-cold syndrome / 中国针灸

ABSTRACT

<p><b>OBJECTIVE</b>To explore the mechanism of warming-needle therapy in treatment of knee osteoarthritis of deficiency-cold syndrome.</p><p><b>METHODS</b>Eight cases of knee osteoarthritis of deficiency-cold syndrome were selected and treated with warming-needle therapy at Guanyuan (CV 4), Qihai (CV 6) , Zosanli (ST 36), etc.. The gene expression profiles before and after treatment in 4 cases who showed better therapeutic effect were compared. Taking ratio < 0.5 or ratio > 2.0 as differentially expression gene and obtaining differentially expression pathway (P < 0.5, n>3) by http//www. DAVID 2006.</p><p><b>RESULTS</b>Two cases were clinically cured, 4 cases were markedly effective, 1 case was effective and 1 case was ineffective. With help of the microarray, 449 differentially expression genes, and 10 differentially expression pathways were obtained including 2 energy metabolism pathways (oxidative phosphorylation, ATP synthetase), 4 cell signal transduction pathways (insulin signal pathway, Toll-like receptor signal pathway, JAK-STAT signal pathway, and MAPK signal pathway) and cell apoptosis pathway.</p><p><b>CONCLUSION</b>Warming-needle therapy is an effective therapy for knee osteoarthritis with deficiency-cold syndrome , which is possibly involved in the control and regulation of many gene expression by various signal transduction pathways.</p>
