AIM: To invesitigate the effect of invigorating blood and dissipating masses traditional Chinese medicine compound drug-containing plasma on the proliferation of rabbit retinal pigment epithelium(RPE)cells treated with platelet derived growth factor(PDGF).

METHODS: Primary cells of RPE cells were obtained by enzymatic digestion, and the primitive culture and subculture of RPE cells were proceeded; prepared blood plasma-contained traditional Chinese medicine compound drug-containing plasma; the fourth genertation rabbit RPE cells were selected as the experimental cells by PDGF of low, medium and high doses(5μg/L, 10μg/L, 20μg/L)for 48h. Suitable concentration was detected and selected in cells experiment by using CCK-8 method. Establishing rabbit model of RPE cell proliferation treated with PDGF. The experimental groups were blank control group(DMEM), normal plasma group, PDGF(10 μg/L)group, PDGF(10 μg/L)+ AG1296(10 μmol/L)group, PDGF(10 μg/L)+ 10% drug-containing plasma, PDGF(10 μg/L)+ 20% drug-containing plasma. Respectively, transwell method was used to determine the migration of rabbit RPE cells after 24h intervention in each group; CCK-8 was used to determine the cell viability OD value of rabbit RPE cells after 48h of intervention in each group.

RESULTS: The plasma containing 10% and 20% concentration of invigorating blood and dissipating masses traditional Chinese medicine compound drug can effectively inhibit cell viability and cell migration of RPE cells treated with PDGF.

CONCLUSION: We found the certain concentration of invigorating blood and dissipating masses traditional Chinese medicine compound drug can effectively inhibit cell viability and cell migration of RPE cells treated with PDGF, which may be an effective treatment for proliferative vitreoretinopathy and provide a new way to study the mechanism of proliferative vitreoretinopathy.
