Aqueous humor provides the necessary nutrition for the lens and transports the metabolites in the eye.It was a liquid that can directly reflect the microenvironment in the eye'and it can be easily obtained during the operation.This review intended to analyze the components of aqueous humor in patients with different types of cataracts'so as to reflect the pathogenesis and development of the disease'evaluate the incidence of postoperative complications and provide reference value for the surgical design of sequential cataract surgery.The aqueous humor components of different types of cataracts showed different degrees of inflammation'oxidative stress and extracellular matrix remodeling.The biomarker of early neuropathy in diabetic cataract was neural cell adhesion molecule-1(NCAM1).Transforming growth factor-β(TGF-β)was the evaluation factor of disease development in patients with pseudoexfoliation syndrome.The relationships between postoperative complications of different types of cataracts and aqueous humor components were as follows:Macular edema after diabetic cataract surgery was associated with tumor necrosis factor-alpha;capsular contraction after high myopic cataract surgery was related to monocyte chemoattractant protein-1(MCP-1)and TGF-β2;Klotho and glutathione S-transferase P 1(GSTP1)were associated with high intraocular pressure after primary open-angle glaucoma complicated by cataract surgery;capsular contraction after retinitis pigmentosa complicated by cataract surgery was associated with matrix metalloproteinases;pro-inflammatory cytokines and fibroblast growth factor 4 in the aqueous humor of congenital cataracts were associated with posterior capsular opacification after surgery.Granulocyte colony stimulating factor 3 and MCP-1 were the main cytokines mediating the pain of the second eye in the binocular sequential cataract surgery short interval(1 wk)'while MCP-1 mediated pain in the long interval(6 wk).The second eye after binocular sequential cataract surgery had a higher level of proinflammatory factors.The components of aqueous humor in patients with different types of cataracts were related to the pathogenesis and postoperative complications of the disease.Monitoring the components of the aqueous humor could help better understand the intraocular microenvironment of different types of cataracts and provide a reference for predicting the development of the disease and implementing relevant targeted therapy. 展开更多

目的检测内皮素(endothelin-1,ET-1)刺激人视网膜色素上皮(retinal pigment epithelial,RPE)细胞后ET-1的自分泌。方法用体外培养的RPE细胞,经10-11mol.L-1、10-9mol.L-1、10-7mol.L-1ET-1作用后,用免疫组织化学和原位杂交检测RPE细胞E... 目的检测内皮素(endothelin-1,ET-1)刺激人视网膜色素上皮(retinal pigment epithelial,RPE)细胞后ET-1的自分泌。方法用体外培养的RPE细胞,经10-11mol.L-1、10-9mol.L-1、10-7mol.L-1ET-1作用后,用免疫组织化学和原位杂交检测RPE细胞ET-1的表达和一氧化氮合酶1(nitric oxide synthase1,NOS1)的表达,并用LeicaQ750图像分析仪定量分析表达量;用放射免疫测定检测细胞调理液中ET-1和6-酮-前列腺素F1α(6-Keto-PGF1α)含量。结果在未经ET-1作用的RPE中ET-1、ET-1 mRNA和NOS1仅见少量细胞微弱表达,3个浓度ET-1作用24h后,图像分析在不同浓度ET-1刺激后均检测出ET-1的表达增强,并有浓度依赖性(F=9.511,P<0.01),NOS1的表达也增强(F=16.113,P<0.01),两者有直线相关性(r=0.685,P<0.05)。在调理液的检测中,ET-1和6-Keto-PGF1α的含量均随着ET-1作用浓度的增加而增加,各作用浓度两者含量均有统计学差异(前者F=23.67,P<0.01;后者F=44.431,P<0.01);并且两者有直线相关性(r=0.85,P<0.01)。结论ET-1刺激RPE细胞表达并分泌ET-1,同时伴随的NOS1表达增加和6-Keto-PGF1α分泌增加可能是针对ET-1的负向调节作用。 展开更多
