RESUMO
We examined the levels of vitreous chemokines and Sho (Zheng in Chinese) of Chinese-Korean-Japanese medicine in diabetic patients. Patients undergoing vitrectomy were classified into Group 1 (no diabetic retinopathy), Group 2 (diabetic retinopathy with no or a few new vessels), and Group 3 (diabetic retinopathy with many new vessels). The levels of IL-8, MCP-1, MIP-1alpha, MIP-1beta, and RANTES in the vitreous fluid were measured using cytometric bead array method. Sho was determined by the standard diagnostic method of Chinese-Korean-Japanese medicine. Vitreous levels of IL-8 and MCP-1 in Groups 2 and 3 were higher than those in Group 1. MIP-1alpha, MIP-1beta, and RANTES levels in Groups 2 and 3 were almost the same as those in Group 1. The percentage of patients with Keishibukuryo-gan (Guizhifuling-wan in Chinese) sho in Group 3 was higher than that in Group 1. In conclusion, vitreous levels of IL-8 and MCP-1 were high in patients with diabetic vitreoretinopathy. Keishibukuryo-gan sho may be associated with diabetic vitreoretinopathy.
