To investigate whether extracts of Danshen and Chuanxinlian (SL) could promote the function recovery in pre-monocytic cell line THP-1 induced by TNF-alpha. SL extracts (0.125-2 g x L(-1)) were used to incubate THP-1 for 24 h before stimulation with TNF-alpha (20 microg x L(-1)), the adhesion, migration, lipid uptake and secretion of THP-1 were observed. SL (0.5-2 g x L(-1)) had obvious effect on decreasing the THP-1 adhesion. The number of passed membrane was much fewer than that of control cells in SL (0.125-2 g x L(-1)). SL (0.125-2 g x L(-1)) reduced the total cholesterol content significantly. The levels of IL-6 in SL (2 g x L(-1)) were significantly decreased,and IL-10 was increased than that before the treatment. SL extracts could promote the function recovery such as adhesion, migration, lipid uptake and secretion of THP-1 induced by TNF-alpha, which probably is one of the mechanisms of inhibit the inflammatory reaction in initiation and development of AS.
