:200-204
 
目的:分析不同程度2型糖尿病视网膜病变的血清生化全套指标,探讨各生化指标与糖尿病性视网膜病变(diabetic retinopathy,DR)程度的相关性。方法:回顾性收集2018年5月至2020年10月在福建医科大学附属第二医院就诊的2型糖尿病患者。根据眼底情况分为3组:糖尿病不伴视网膜病变(non-diabetic retinopathy,NDR)组(17例)、糖尿病伴非增殖性视网膜病变(non-proliferative diabetic retinopathy,NPDR)组(29例)、糖尿病伴增殖期视网膜病变(proliferative diabetic retinopathy,PDR)组(34例)。采用SPSS 24.0分析比较3组血清生化全套各指标水平,对差异指标与DR相关性采用Pearson相关分析与多重线性回归分析。结果:3组年龄差异无统计学意义(P>0.05);3组的总蛋白、白蛋白、白球比、钙浓度差异均有统计学意义(均P<0.05)。组间比较发现NPDR和PDR组总蛋白、白蛋白、白球比、钙浓度低于NDR组,差异有统计学意义(P<0.05)。Pearson相关分析显示总蛋白(r=?0.290)、白蛋白(r=?0.304),钙浓度(r=?0.252)与DR呈负相关(均P<0.05),多重线性回归提示总蛋白、白蛋白及血钙浓度是DR保护因素(P<0.05)。结论:血清指标总蛋白、白蛋白及血钙浓度与DR成负相关,在生理范围内将这些指标维持相对较高的水平,或许可以为糖尿病视网膜病变的防治提供新思路。
Objective: To analyze the serum biochemical indexes of different degrees of type 2 diabetic retinopathy, and the correlation between biochemical indexes and the degree of diabetic retinopathy (DR). Methods: Patients with type 2 diabetes admitted to the Fujian Medical University 2nd Affiliate Hospital from May 2018 to October 2020 were retrospectively collected. The patients were divided into 3 groups according to fundus conditions: non-diabetic retinopathy (NDR) group (n=17), diabetes with non-proliferative diabetic retinopathy (NPDR) group (n=29),diabetes with proliferative diabetic retinopathy (PDR) group (n=34). SPSS 24.0 was used to compare the levels of a complete set of serum biochemical indexes in the three groups. Pearson correlation analysis and multiple linear regression analysis were used for the correlation between the different indexes and DR. Results: There was no statistically significant difference in age between the three groups. The differences in total protein, albumin, white sphere ratio, and calcium concentration of the three groups were statistically significant (P<0.05). The comparison between the groups showed that the total protein, albumin, white sphere ratio, and calcium concentration in the NPDR and PDR groups were lower than those in the NDR group. The difference was statistically significant (P<0.05). Pearson correlation analysis showed that total protein (r=?0.290), albumin (r=?0.304), and
calcium concentration (r=?0.252) were negatively correlated with DR (all P<0.05). Multiple linear regression indicated total protein, albumin and blood calcium concentration were the protective factors of DR (P<0.05).Conclusion: This study found that serum levels of total protein, albumin, and blood calcium levels are negatively correlated with DR. Maintaining a relatively high level of these indexes within the physiological range may provide new ideas for the prevention and treatment of diabetic retinopathy.

EDN1和CFH的基因多态性与2型糖尿病增生性视网膜病变的相关性

Association of EDN1 and CFH gene polymorphisms with proliferative diabetic retinopathy in type 2 diabetes mellitus

:374-382
 
目的:探讨基因多态性与2型糖尿病(type 2 diabetes mellitus,T2DM)患者发生增生性糖尿病性视网膜病变(proliferative diabetic retinopathy,PDR)的相关性。方法:2019年1月至2020年9月桂林医学院附属医院收治的700名T2DM患者,分为无糖尿病性视网膜病变(non-diabetic retinopathy,NDR)组(n=386)与PDR组(n=314)。收集临床基本资料,抽取患者外周血,使用竞争性等位基因特异性聚合酶链反应(kompetitive allele specific polymerase chain reaction,KASP)基因分型检测法检测两组患者血清中的内皮素-1(endothelin 1,EDN1)基因的rs5370位点和补体因子H(complement factor H,CFH)基因的rs800292位点基因型。用logistic回归分析这2个基因位点的多态性与广西汉族T2DM患PDR的关系。结果:收缩压、使用胰岛素治疗以及肾小球滤过率(glomerular filtration rate,GFR)的分析结果显示两组间差异有统计学意义(P收缩压=0.025,P胰岛素=0.001,PGFR=0.013)。排除以上混杂因素后,EDN1基因的rs5370位点上TT基因型与PDR易感性呈正相关(P=0.03,OR=2.973;adj.P=0.011,OR=2.718);CFH基因的rs800292位点上AA基因型与PDR易感性呈正相关(P=0.037,OR=1.949;adj.P=0.044,OR=2.058)。结论:收缩压增高、GFR降低可能与T2DM患者发生PDR相关。EDN1基因的rs5370位点与CFH基因的rs800292位点的多态性与广西汉族人群的PDR易感性显著相关。
Objective: To investigate the relationship between gene-polymorphisms and proliferative diabetic retinopathy in patients who have type 2 diabetes mellitus (T2DM). Method: A total of 700 hospitalized T2DM patients were included in this study from January 2019 to September 2020. They were divided into two groups: the no-diabetic retinopathy (NDR) group (n=386) and the proliferative diabetic retinopathy (PDR) group (n=314). Basic clinical data were collected, and clinical indexes affecting diabetic retinopathy were analyzed. Two tag SNPs rs5370 in endothelin 1 (EDN1) and rs800292 in complement factor H (CFH) were examined using kompetitive allele-specific polymerase chain reaction (KASP) genotyping assays. Logistic regression was used to analyse the relationship between the polymorphisms of these two SNPs and PDR in a Guangxi Han population with T2DM. Results: Significant differences were found through the analysis of the systolic blood pressure—whether using insulin or not—and the glomerular filtration rate (GFR) between the two groups (Psystolic blood pressure=0.025, Pinsulin=0.001, PGFR=0.013) The TT genotype of rs5370 was determined to be associated with an increased risk of PDR (P=0.03, OR=2.973; adj.P=0.011, OR=2.718). The AA genotype of rs800292 was also determined to be associated with an increased risk of PDR (P=0.037, OR=1.949; adj.P=0.044, OR=2.058). Conclusion: Increased systolic blood pressure and decreased GFR may be associated with PDR in patients with T2DM. The rs5370 polymorphism of the EDN1 gene and the rs800292 polymorphism of the CFH gene are significantly associated with the risk of PDR in Guangxi’s Han population.

:298-306
 
目的:探讨2型糖尿病(type 2 diabetes mellitus,T2DM)患者二甲双胍治疗与糖尿病性视网膜病变(diabetic retinopathy,DR)的相关性。方法:回顾2015年9月至2020年8月在中日友好医院眼科就诊的1 891例T2DM患者的临床资料,对病程≥10年的324例T2DM患者的一般资料、内科疾病史、糖尿病治疗史、眼科检查和实验室血生化指标进行回顾性病例研究。根据是否接受二甲双胍治疗分为二甲双胍治疗组与非二甲双胍治疗组,根据眼底检查结果同时结合DR临床诊断标准,将DR分为无明显DR、非增生性DR及增生性DR。采用logistic多因素回归分析判断年龄、性别、糖尿病发病年龄、糖尿病病程、高血压病程、高血脂病程、吸烟年数、体重指数、胰岛素治疗及空腹血糖、糖化血红蛋白、总胆固醇、三酰甘油、尿酸和血肌酐水平对结局变量的影响。结果:在DR的发病风险方面,二甲双胍治疗组与非二甲双胍治疗组的差异无统计学意义(P>0.05)。对T2DM患者DR发生及不同分期的相关变量行单因素及多因素分析,结果显示吸烟年数、空腹血糖及肌酐均与DR发病呈正相关(均P<0.05),而年龄与DR发病呈负相关(P<0.01),糖尿病发病年龄与DR发生呈显著负相关(OR=0.95,95%CI:0.92~0.98,P=0.0003)。在二甲双胍治疗的T2DM患者中,二甲双胍的疗程(OR=1.02,95%CI:0.96~1.08,P>0.05)及平均剂量(OR=1.50,95%CI:0.79~2.84,P>0.05)与DR的发生与进展均无显著相关性;女性DR发生与进展的风险较男性低(P<0.05);合并胰岛素治疗与DR发生呈明显正相关(OR=3.11,95%CI:1.59~6.07,P<0.01);吸烟年数长、糖化血红蛋白及尿酸水平高于正常范围均与DR的发生与进展呈正相关(P<0.05)。在口服二甲双胍患者中,未使用胰岛素治疗组和联合使用胰岛素组的DR发病风险有显著差异(P<0.01);而未口服二甲双胍患者中,胰岛素治疗与DR发生呈正相关(OR=12.43,95%CI:3.75~41.19,P<0.0001)。结论:病程10年以上T2DM患者中,二甲双胍治疗与DR发生与进展均无显著相关性。
Objective: To investigate the correlation between metformin therapy and diabetic retinopathy (DR) in patients with type 2 diabetes mellitus (T2DM). Methods: The clinical data of 1 891 patients with type 2 diabetes mellitus attending the ophthalmology department of China-Japan Friendship Hospital from September 2015 to August 2020 were reviewed. A retrospective study was performed on 324 cases of these T2DM patients with disease duration ≥10 years. Medical records of all patients including general information, history of medical disease, diabetes treatment, ophthalmologic examination and blood biochemical indices were collected. According to whether metformin treatment was received or not, the patients were divided into a metformin-treated and a non-metformin-treated groups. DR is classified into non-obvious DR, non-proliferative DR and proliferative DR according to the fundus examination and the clinical diagnostic criteria of DR. Logistic multiple regression analysis was used to determine the effects of age, sex, age of DM onset, duration of DM, duration of hypertension,
duration of hyperlipidemia, years of smoking, body mass index, insulin treatment and fasting glucose, glycated hemoglobin, total cholesterol, triglycerides, uric acid and blood creatinine levels on DR. Results: There was no statistically significant difference in the risk of developing DR between the metformin-treated and non-metformin-treated groups (P>0.05). Univariate and multifactorial analyses of variables related to the occurrence and different stages of DR in patients with T2DM showed that years of smoking, fasting glucose and creatinine were positively associated with DR (P<0.05), while age was negatively associated with DR (P<0.01), and age of DM onset was significantly negatively associated with DR (OR=0.95, 95%CI: 0.92 to 0.98, P=0.0003). In T2DM patients treated with metformin, neither the duration of metformin (OR=1.02, 95%CI: 0.96 to 1.08, P>0.05) nor the mean dose(OR=1.50, 95%CI: 0.79 to 2.84, P>0.05) was significantly associated with developing DR. The risk of developing DR was lower in women than in men (P<0.05); combined insulin therapy was significantly positively correlated with the risk of DR (OR=3.11, 95%CI: 1.59 to 6.07, P<0.01); long-term smoking, glycosylated hemoglobin and uric acid levels higher than normal were positively associated with DR (P<0.05). In metformin users, there was a significant difference in the risk of developing DR between the no-insulin treatment group and the combined insulin group (P<0.01); and among patients not using metformin, insulin therapy was positively associated with the occurrence of DR (OR=12.43, 95%CI: 3.75 to 41.19, P<0.0001). Conclusion: There was no significant association between metformin treatment and DR among patients with T2DM for >10 years.
