International Journal of Ophthalmology(English edition) 2016年第8期9卷 1121-1126页

作者： Xia Qi sheng-wei ren Feng Zhang Yi-Qiang Wang State Key Laboratory Cultivation Base Shandong Provincial Key Laboratory of Ophthalmology Shandong Eye InstituteShandong Academy of Medical Sciences Linyi People's Hospital Henan Eye Institute & Henan Eye Hospital Eye Department of Henan People's Hospital People's Hospital of Zhengzhou University MOH Key Lab of Thrombosis and Hemostasis Collaborative Innovation Center of Hematology Jiangsu Institute of Hematology the First Affiliated Hospital of Soochow University

AIM: To research the two homologous predicted proline -rich protein genes, Mus musculus predicted gene 4736 (MP4) and proline-rich protein BstNI subfamily 1 (Prb1) which were significantly upregulated in cultured corneal organs when encountering fungal pathogen preparations. This study was to confirm the expression and potential functions of these two genes in ocular surface. METHODS: A Pseudomonas aeruginosa keratitis model was established in Balb/c mice. One day post infection, mRNA level of MP4 was measured using real-time polymerase chain reaction (PCR), and MP4 protein detected by immunohistochemistry (IHC) or Western blot using a customized polyclonal anti -MP4 antibody preparation. Lacrimal glands from normal mice were also subjected to IHC staining for MP4. An online bioinformatics program, BioGPS, was utilized to screen public data to determine other potential locations of MP4. RESULTS: One day after keratitis induction, MP4 was upregulated in the corneas at both mRNA level as measured using real -time PCR and protein levels as measured using Western blot and IHC. BioGPS analysis of public data suggested that the MP4 gene was most abundantly expressed in the lacrimal glands, and IHC revealed that normal murine lacrimal glands were positive for MP4 staining. CONCLUSION: MP4 and Prb1 are closely related with the physiology and pathological processes of the ocular surface. Considering the significance of ocular surface abnormalities like dry eye, we propose that MP4 and Prb1 contribute to homeostasis of ocular surface, and deserve more extensive functional and disease correlation studies.

目的:观察角膜硬度参数(SP-A1)在不同年龄以及不同严重程度分级圆锥角膜患者中的特征。方法:横断面研究。连续纳入2018-09/2020-12在河南省立眼科医院诊断为圆锥角膜的患者247例345眼,平均年龄24.51±6.38岁。根据年龄将患者分为≤20岁组、21~30岁组和≥31岁组。采用Amsler-Krumeich(AK)分级将圆锥角膜严重程度分为AK1、AK2、AK3和AK4。测量患者视力、角膜平坦曲率(K1)、角膜陡峭曲率(K2)、角膜平均曲率(Km)、最薄点角膜厚度(TCT)。应用角膜生物力学分析仪(Corvis ST)测量患者的角膜SP-A1以及眼压、最大形变振幅(DA Max)、第1次压平时间(A1T)、第1次压平速度(A1V)、第2次压平时间(A2T)、第2次压平速度(A2V)、凹面半径(Radius)、生物力学校正眼压(bIOP)。采用Spearman秩相关分析SP-A1与其他参数的相关性。采用单因素方差分析比较不同年龄组以及不同疾病严重程度间SP-A1差异。结果:不同年龄组间性别构成比、最佳矫正视力(LogMAR)、眼压、K1、K2、Km、TCT和严重程度分级比较差异无统计学差异(P>0.05)。圆锥角膜患者SP-A1与年龄呈弱的正相关(r_(s)=0.137,P=0.011)。≥31岁组患者角膜SP-A1显著高于≤20岁组和21~30岁组(P<0.05)。≤20岁和21~30岁组中SP-A1与K1、K2和Km呈负相关,≥31岁组中SP-A1仅与K2呈负相关(P<0.05)。此外,总人群及各年龄组中SP-A1与DA Max、A1V和A2T呈负相关(P<0.05),与TCT、眼压、bIOP、A1T、A2V和Radius呈正相关(P<0.05)。随着疾病严重程度的增加年龄≤20岁组和21~30岁组圆锥角膜患者的SP-A1逐渐降低(P<0.05)。年龄≥31岁的圆锥角膜患者,AK1组与AK4组、AK2组与AK3组、AK2组与AK4组SP-A1的比较差异有统计学意义(P=0.008、0.035、0.001)。结论:圆锥角膜患者SP-A1与年龄正相关,且在年龄≤30岁的患者中,SP-A1会随着疾病严重程度增加而逐渐降低。
