To investigate the relationship between levels of transforming growth factor beta (TGF-beta), matrix metalloproteinase (MMP) and tissue inhibitors of MMP (TIMP) in the aqueous humor (AH) and plasma (PL) of myopic patients.
Aqueous humor and plasma were collected intraoperatively from 37 myopic patients with various axial lengths (AL) during ICL surgery. The concentrations of TGF-β1, TGF-β2, TGF-β3, MMP-1, MMP-2, MMP-7, MMP-9, MMP-10, TIMP-1, TIMP-2, TIMP-3 and TIMP-4 were measured using Luminex xMAP Technology kits (Milliplex xMAP kits). The association between TGFβ and MMP/TIMP levels were analyzed based on the Spearman's correlation test or Pearson's correlation test.
There was a negative correlation between TGF-β1 and MMP-1, TIMP-2, TIMP-3 and TIMP-4 in the AH, and a positive correlation between TGF-β1 and MMP-1 in the PL. In the AH, levels of TGF-β2 were positively correlated with levels of TIMP-3 (r=0.441; P < 0.001). In the PL, levels of TGF-β2 also correlated positively with levels of TIMP-3 (r=0.427; P < 0.001)).
The level of TGF-β2 was the highest among TGF-βs in the AH. A consistent positive correlation between TGF-β2 and TIMP-3 was found both in the AH and PL, indicating that systemic levels of TGF-β2 and MMPs/TIMPs may also play a role in myopic progression.
研究转化生长因子-β（TGF-β）、基质金属蛋白酶（MMP）及其组织抑制剂（TIMP）在近视患者房水（AH）和血浆（PL）中的水平关系。
在 ICL 手术中，从 37 名具有不同眼轴（AL）的近视患者中收集房水和血浆。使用 Luminex xMAP 技术试剂盒（Milliplex xMAP 试剂盒）测量 TGF-β1、TGF-β2、TGF-β3、MMP-1、MMP-2、MMP-7、MMP-9、MMP-10、TIMP-1、TIMP-2、TIMP-3 和 TIMP-4 的浓度。根据 Spearman 相关检验或 Pearson 相关检验分析 TGFβ 与 MMP/TIMP 水平之间的关系。
在 AH 中，TGF-β1 与 MMP-1、TIMP-2、TIMP-3 和 TIMP-4 呈负相关，与 MMP-1 在 PL 中呈正相关。在 AH 中，TGF-β2 水平与 TIMP-3 水平呈正相关（r=0.441；P<0.001）。在 PL 中，TGF-β2 水平也与 TIMP-3 水平呈正相关（r=0.427；P<0.001）。
TGF-β2 在 AH 中的 TGF-β 中含量最高。在 AH 和 PL 中均发现 TGF-β2 与 TIMP-3 之间存在一致的正相关，表明全身 TGF-β2 水平和 MMPs/TIMPs 也可能在近视进展中发挥作用。
