摘　　要：目的比较社区2型糖尿病患者与正常人群泪液检测指标的差异,为研究糖尿病患者干眼患病率及其发病机制提供理论依据.方法采用病例对照研究设计,2016年4月20日至6月6日在社区干眼流行病学调查过程中随机抽取受试对象.糖尿病组79例158眼,年龄性别相匹配、未患有糖尿病的社区人群作为正常对照组,74人148眼,完成泪膜破裂时间(BUT)、基础泪液分泌试验(SⅠt)、角膜荧光素染色检测及泪液采集.采用ELISA法测定泪液黏蛋白-5AC(MUC-5AC)、基质金属蛋白酶-9(MMP-9)、糖基化终产物受体(RAGEs)、胰岛素含量.参照2013年《干眼临床诊疗专家共识》将糖尿病组患者亚分为干眼组和非干眼组.结果糖尿病组BUT、SⅠt值低于对照组,角膜荧光素染色值高于对照组;糖尿病组的MMP-9、RAGE高于对照组,胰岛素值、MUC-5AC低于对照组,差异均有统计学意义(均P<0.05).糖尿病人群中干眼组女性患者数量多于男性,差异有统计学意义(t=4.35,P=0.04);干眼组糖尿病病程长于非干眼组,差异有统计学意义(t=2.56,P=0.01);干眼组MMP-9含量为(1052.37±157.68)pg/ml,明显高于非干眼组的(459.11±258.67)pg/ml,差异有统计学意义(t=11.92,P<0.01);干眼组MUC-5AC含量为(867.83±121.82)pg/ml,明显低于非干眼组的(972.93±153.53)pg/ml,差异有统计学意义(t=-3.30,P<0.01).Pearson相关分析显示,MMP-9与BUT呈负相关(r=-0.349,P<0.01),与角膜荧光素染色呈正相关(r=0.181,P=0.026),MUC-5AC与SⅠt呈正相关(r=0.367,P<0.01).结论社区糖尿病患者罹患干眼与泪液中MUC-5AC减少、MMP-9增加显著相关.Objective To compare the tear related indexes of patients with type-2 diabetes and the healthy subjects, analyze the functions of tear film of these two groups and provide significant theoretical evidences for the causes of the increased prevalence of dry eye in patients with type-2 diabetes and their pathogenesis. Methods A case-control study was designed.During the epidemiological investigation of dry eye in communities, 79 patients with diabetes and 74 normal healthy subjects were randomly selected as participants in this case-contol study.Dry eye tests including tear film break-up time (BUT), SchirmerⅠtest (SⅠt) and corneal fluorescein staining were performed.The tears were collected to detect mucoprotein-5AC (MUC-5AC), matrix metalloproteinase 9 (MMP-9), receptor of advanced glycation endproducts (RAGEs) and the content of insulin.The diagnosis standard referred to Experts Consensus on Clinical Diagnosis and Treatment of Dry Eye published in 2013.The study was followed the Declaration of Helsinki.This study protocol was approved by Medical Ethics Committee of the Shanghai General Hospital, Shanghai Jiaotong University(No.2016KY005), and written informed consent was obtained from all subjects. Results There were significant differences between 79 diabetes patients and 74 normal healthy subjects in the value of BUT, SⅠt and corneal fluorescein staining (all at P<0.05). The value of BUT and SⅠt in patients with diabetes were lower than those in the control group, while the corneal fluorescein staining scores of patients were higher than those of normal healthy subjects, with significant differences (P<0.05). In addition, compared with normal healthy subjects, the diabetic patients were higher in the value of MMP-9 and RAGEs, but lower in the content of insulin and MUC-5AC, with significant differences (P<0.05). There were significant differences in gender, diabetes duration, MMP-9, and MUC-5AC between the dry and non-dry eyes in the diabetic group (P<0.05). Women were more likely to develop dry eyes wit
