摘要
Purpose: To study the relationships between matrix metalloproteinases (MMP)-2, MMP-3, and tissue inhibitors of matrix metalloproteinases (TIMP)-1, TIMP-2, and TIMP-3 aqueous humor levels in patients with high myopia or cataract.Materials and Methods: MMPs and TIMPs protein levels in 65 aqueous humor samples collected from patients with high myopia or cataract during cataract or clear lens extraction surgery were measured with the Luminex xMAP Technology. The relationship between MMPs and TIMPs levels was analyzed with Spearman’s correlation test.Results: MMP-2 levels, but not MMP-3 levels, were increased in the aqueous humor from high-myopia patients. Levels of TIMP-1, -2, and -3 were positively and very significantly correlated with the MMP-2 levels (TIMP-1: r=0.626, p < 0.001; TIMP-2: r = 0.545, p < 0.001; TIMP-3: r = 0.439, p < 0.001). TIMP-2 and-3 levels did not significantly correlate with MMP-3 levels (TIMP-2: r = 0.175, p > 0.05; TIMP-3: r = 0.127, p > 0.05) and TIMP-1 levels only marginally correlated with MMP-3 levels (r = 0.278, 0.01< P < 0.05).Conclusions: Compared to the present findings with the relationship of MMPs and TIMPs in other fields of medicine, our results are consistent with the homeostasis hypothesis that the increase of TIMPs serves as a compensation reaction to inhibit the excessive degradation caused by the increase of MMPs and limits the development of myopia.
