糖尿病视网膜病变(diabetic retinopathy,DR)是世界范围内劳动年龄人口视力损伤的主要原因。糖尿病前期和DR临床前期患者作为罹患DR的高危人群，在该阶段可发现视网膜神经元形态功能及视网膜微小血管的改变。视网膜及神经纤维层厚度的变化可部分反映视网膜神经元结构改变；色觉、对比敏感度、视野及视觉电生理等变化可反映视网膜神经元功能改变。随着光学相关断层扫描血管成像技术的发展，临床可以检测出DR之前视网膜微血管的改变。此外，许多生物标志物也可以预测和评估DR。由于目前还没有方法可以阻止DR的发生与进展，临床可以通过观察以上视网膜的改变更为及时地发现DR，以降低其患病率，最大限度地减少DR带来的视力损伤。

Diabetes retinopathy (DR) is the main cause of visual impairment in the working population worldwide. Patients with pre-diabetes and pre-clinic diabetic retinopathy are regarded as in high risk group of DR. The changes in morphology and function of renal neurons and retinal micro-vessels can be found in these patients at this stage. The changes of retinal nerve structure can be partly reflected by changes in the thickness of retina and nerve fiber layer. The changes in function of retinal neurons can be reflected by changes in color vision, contrast sensitivity, visual field and visual electrophysiology.With the development of optical coherence tomography angiography, changes in retinal micro-vessels can be observed prior to clinical detection of DR. In addition, many biomarker can also predict and evaluate DR. Since there is no way to prevent the occurrence and progress of DR at present, more attention should be paid in DR by observing the changes inthe retina mentioned above timely, to reduce its incidence and minimize the visual damage caused by DR.

糖尿病视网膜病变(diabetes retinopathy, DR)是糖尿病常见的眼部并发症，其病理过程复杂，涉及多种细胞及炎症因子。Müller细胞作为视网膜主要支持细胞，在DR中不仅产生白介素-17(interleukin-17, IL-17)，还作为其主要靶点发挥作用，通过谷氨酸代谢异常、血管内皮生长因子(vascular endothelial growth factor, VEGF)分泌增加及调控参与DR的病理过程，加重炎症反应。IL-17主要由辅助性T细胞17(T helper cell 17, Th17)分泌，通过促进多种炎症介质(如细胞因子、趋化因子和金属蛋白酶)的分泌，增强炎症反应，导致视网膜微血管损害和神经元凋亡，促进DR的发展。高糖环境下，Müller细胞功能受损，IL-17进一步加剧其功能障碍形成恶性循环。研究表明，阻断IL-17及核因子-κB激活剂1(Nuclear factor-kappa B activator 1, Act1)/肿瘤坏死因子受体关联因子6(tumor necrosis factor receptor associated factor 6, TRAF6)/核因子-κB(Nuclear factor-kappa B, NF-κB)信号通路可减轻DR的病理改变，为DR的治疗提供了新的思路。因此，深入研究IL-17与Müller细胞在DR中的相互作用机制，对于研究该疾病的发病机制及开发精准有效的治疗策略具有重要意义。

Diabetes retinopathy (DR) is a common ocular complication of diabetes, characterized by a complex pathological process involving multiple cells and inflammatory factors. Müller cells, as the primary supporting cells of the retina, not only produce interleukin-17 (IL-17) but also serve as a primary target in DR. They participate in the pathological process of DR by contributing to abnormal glutamate metabolism, increased secretion of vascular endothelial growth factor (VEGF), and regulatory functions, thereby exacerbating the inflammatory response. IL-17 is primarily secreted by T helper cell 17 (Th17) cells and enhances the inflammatory response by promoting the secretion of various inflammatory mediators (such as cytokines, chemokines, and metalloproteinases), leading to retinal microvascular damage and neuronal apoptosis, which accelerates the progression of DR. In a high-glucose environment, Müller cell function is impaired, and IL-17 further exacerbates this dysfunction, creating a vicious cycle. Studies have shown that blocking the IL-17 and Act1/TRAF6/NF-κB signaling pathways can mitigate the pathological changes associated with DR, providing new insights for the treatment of this disease. Therefore, conducting in-depth research on the interaction mechanism between IL-17 and Müller cells in DR is of great significance for exploring the pathogenesis of this disease and developing precise and effective treatment strategies.

糖尿病性黄斑水肿(diabetic macular edema, DME)是糖尿病最常见和最严重的并发症之一，也是中青年劳动人群常见的致盲原因。DME病理生理机制复杂，是多种因素相互作用的结果，控制这些危险因素是降低发病率的关键。DME是全身病相关性眼病，其发生与发展受众多危险因素的影响，但此前文献对其总结不足，本文从全身因素及眼部因素两个方面就DME的危险因素进行综述。全身危险因素主要包括血糖控制欠佳、糖尿病病程长、高血压、血脂代谢紊乱、肥胖、肾功能异常、妊娠状态、降糖药物使用、贫血、阻塞性睡眠呼吸暂停低通气综合征、遗传因素、吸烟、饮酒、高血钙、低血镁等；而其眼部危险因素主要包括白内障、青光眼及玻璃体切割术、全视网膜激光光凝术、合并视网膜静脉阻塞和相关细胞因子等。深入认识和理解这些危险因素，有助于更好地预防和早期治疗DME，同时为治疗糖尿病视网膜病变过程中控制DME进展提供指引和参考。但是，其中一部分因素还存在一定争议，更多的DME危险因素仍有待进一步探索，期望在不久的将来，更多基础和前瞻性临床研究为DME危险因素及治疗提供高质量的证据。

Diabetic macular edema (DME) is one of the most common and severe complications of diabetes, and it is a leading cause of blindness in the working-age population. The pathophysiology of DME is complex, resulting from the interplay of various factors. Controlling these risk factors is crucial in reducing the incidence of DME. As a systemic diseaserelated ocular condition, the onset and progression of DME are influenced by numerous risk factors. However, previous literature has provided insufficient summaries of these factors. This review aims to summarize the risk factors for DME from both systemic and ocular perspectives. The systemic risk factors primarily include poor glycemic control, prolonged duration of diabetes, hypertension, dyslipidemia, obesity, renal dysfunction, pregnancy, the use of hypoglycemic medications, anemia, obstructive sleep apnea-hypopnea syndrome, genetic factors, smoking, alcohol consumption, hypercalcemia, and hypomagnesemia. On the other hand, ocular risk factors include cataracts, glaucoma and vitrectomy, panretinal photocoagulation, coexisting retinal vein occlusion, and related cytokines. A deeper understanding of these risk factors will aid in the better prevention and early treatment of DME, while also providing guidance and reference for controlling the progression of DME during the treatment of diabetic retinopathy. However, some of these factors remain controversial, and additional DME risk factors still need to be explored. It is hoped that, in the near future, more 

foundational and prospective clinical studies will provide high-quality evidence on DME risk factors and treatments.

糖尿病视网膜病变是最为常见的糖尿病微血管并发症，主要由糖尿病引起的机体代谢紊乱导致。而然在临床工作中发现，部分患者通过单纯控制血糖以延缓糖尿病视网膜病变进展，所取得效果不甚理想，一些其他因素对于糖尿病视网膜病变的发生、发展，也起到不可忽视的作用。研究表明，在并发高脂血症的糖尿病视网膜病变患者中，胆固醇代谢异常是诱发视网膜病变的主要原因之一。胆固醇代谢异常通过减弱肝脏X受体，导致胆固醇在视网膜上不断积累，降低视网膜血管内皮功能，从而造成视网膜缺血、缺氧环境的形成，又可通过增加炎症因子和细胞黏附分子-1的表达，使原本病态的糖尿病视网膜血管变得更加脆弱，该文总结了糖尿病视网膜病变的病理因素，对比分析当前糖尿病视网膜病变的主要治疗手段，通过分析胆固醇逆向转运(cholesterol reverse transport,RCT)途径转运对糖尿病视网膜病变发生、发展的影响，发现降低高血脂可提高糖尿病视网膜病变的治愈率，这将为糖尿病视网膜病变的临床防治工作提供新思路。

Diabetic retinopathy is the most common diabetic microvascular complication, which is mainly caused by metabolic disorders caused by diabetes. However, in clinical work, it is found that some patients do not achieve satisfactory results in delaying the progress of diabetic retinopathy by simply controlling blood sugar, and some other factors contribute to the occurrence and development of diabetic retinopathy. Also played a role that can not be ignored. Studies have shown that abnormal cholesterol metabolism is one of the main causes of retinopathy in diabetic retinopathy patients with hyperlipidemia. Abnormal cholesterol metabolism leads to the accumulation of cholesterol in the retina and the decrease of retinal vascular endothelial function by weakening the X receptor in the liver, resulting in the formation of retinal ischemia and hypoxia environment. it can also increase the expression of inflammatory cytokines and cell adhesion molecule-1 to make the originally morbid retinal vessels more fragile. This paper summarizes the pathological factors of diabetic retinopathy. By comparing and analyzing the main treatment methods of diabetic retinopathy at present, and by analyzing the influence of cholesterol reverse transport (cholesterolreversetransport,RCT) pathway on the occurrence and development of diabetic retinopathy, it is found that reducing hyperlipidemia can improve the cure rate of diabetic retinopathy, which will provide new ideas for the clinical prevention and treatment of diabetic retinopathy.

糖尿病视网膜病变是糖尿病引起的微血管病变之一，是不可逆性致盲的眼病。根据其病程可分为根据其病程可分为非增殖期和增殖期，其中还包括糖尿病性黄斑水肿。全科医师需要检测量裸眼视力、矫正视力和眼压，通过裂隙灯显微镜评估眼前节以及眼底检查来评估眼部整体情况。控制血糖、血压、血脂对改善预后很重要。需要重视餐前、餐后血糖，糖化血红蛋白和代谢记忆，一线降血压药物包括血管紧张素转化酶抑制剂和血管紧张素Ⅱ受体阻断剂，调脂药物首选他汀类，而非诺贝特有额外的视网膜保护作用。干预生活方式，宣教，早期发现也同样重要。全科医师需要进行眼底筛查和评分，及时转诊至眼科治疗。眼科治疗包括全视网膜激光光凝术、经平坦部玻璃体切除术、玻璃体抗血管内皮生长因子药物注射术。

Diabetic retinopathy is one of the microvascular diseases caused by diabetes, it is an irreversible blindness eye disease. According to its course, it can be divided into non-proliferative diabetic retinopathy and proliferative diabetic retinopathy, including diabetic macular edema. Te general practitioner needs to measure the uncorrected visual acuity, corrected visual acuity intraocular pressure, use the slit lamp microscope to exam the anterior segment and fundus to evaluate the overall condition of the eye. Controlling blood glucose, blood pressure and blood lipid is very important to improve the prognosis. Attach importance to pre- and postprandial blood glucose, glycosylated hemoglobin and metabolic memory should be carried out. The first-line antihypertensive drugs are angiotensin converting enzyme inhibitors and angiotensin II receptor blockers. Statins are the first choice for lipid-lowering drugs, fenofibrate has additional protective efect of retinal. Intervention in lifestyle, education and early detection are is important. Te general practitioner needs to perform fundus screening and scoring, timely refer to ophthalmology department for treatment. Ophthalmic treatment includes panretinal laser photocoagulation, pars plana vitrectomy, and intravitreal injection of anti-vascular endothelial growth factor drugs.

Objective: To analyze the clinical characteristics of endogenous endophthalmitis caused by Klebsiella pneumoniae in diabetic patients, and summarize the treatment experience and evaluate its prognosis. Methods: A retrospective case analysis was performed on 7 patients (8 eyes) with endogenous endophthalmitis caused by Klebsiella pneumoniae, who were admitted to the Affiliated Eye Hospital of Shandong University of Traditional Chinese Medicine from January 2019 to August 2022. The age, gender, origin of infection, time of treatment, visual acuity before and after treatment, intraocular pressure, slit lamp examination, fundus examination, ophthalmic B-mode ultrasound, treatment methods, infection control and recurrence were analyzed. Results: The mean age of the seven patients was (63±17.6). There were five males (71.4%) and 2 females (28.6%). Postoperative visual acuity was NLP in seven eyes (87.5%) and LogMAR visual acuity was 0.2 in one eye (12.5%). Visual acuity was related to the patient’s visit time and the visual acuity at visit. Six cases (85.7%) had fever before treatment. Fever was a risk factor for Klebsiella pneumoniae endophthalmitis infection. Eight eyes (100%) had mixed conjunctival congestion, and one eye (12.5%) had abscess in the anterior chamber. Seven eyes (87.5%) underwent vitrectomy combined with intravitreal drug injection, and one eye (12.5%) underwent intravitreal drug injection alone. Infections were controlled in all eight eyes without enucleation. Intraocular pressure was normal during the follow-up period, and there was no infection recurrence. Conclusions: Klebsiella pneumoniae is the main pathogen of endogenous endophthalmitis and is prone to occur in people with diabetes. The onset of the disease progresses rapidly. The early clinical manifestations are not typical, and the prognosis is closely related to the duration of the disease and the timing of treatment. Early treatment can restore some vision.

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.

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 (P_{systolic blood pressure}=0.025, P_insulin=0.001, P_GFR=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.

目的：测量医联体糖尿病患者眼科随访依从性及相关的健康信念，分析其影响因素。方法：采用便利抽样的方法，使用中文版糖尿病眼科随访依从性问卷对在广州医科大学附属第二医院所辖医联体内的334例糖尿病患者进行调查。结果：仅24.3%的受访者在过去的1年中接受过眼科散瞳检查，受访者眼科随访健康信念的总体评分为3.09±0.64，其中感知的益处和威胁维度评分最高，行为线索维度评分最低。糖尿病类型、就医倾向、合并其他糖尿病并发症、医联体相关知识和家庭类型是糖尿病患者眼科随访健康信念的主要影响因素。结论：医联体糖尿病患者眼科随访健康信念处于一般水平，缺乏行为线索支持，提示在糖尿病眼部并发症筛查和防治过程中，医联体应发挥下筛上转的功能，通过对障碍因素的干预，提高辖区糖尿病患者接受眼科随访的依从性。

Objective: To measure the adherence to ophthalmology follow-up and the related health belief of patients with diabetes in medical alliance, and analyze the influencing factors. Methods: Totally 334 community-dwelling patients with diabetes mellitus were recruited in a medical alliance in Guangzhou by convenient sampling method. They were investigated by the Chinese version of the Compliance with Annual Diabetic Eye Exams Survey (CADEES-C). Results: Dilated fundus examination within the last year were only reported by 24.3% of respondents. The mean score of the CADEES-C was 3.09±0.64, with the highest score in perceived benefit and threat dimensions and the lowest score in behavioral cue dimension. The factors that mainly influence the adherence to ophthalmology follow-up and their related health beliefs of patients with diabetes are types of diabetes, propensity to seek treatment, other complications of diabetes, knowledge of medical alliance and family pattern. Conclusion: The adherence to ophthalmology follow-up and the related health belief of patients with diabetes are at low level with the deficiency of behavioral cues. It is suggested that medical alliance should play a critical role to improve the status quo by developing more screening and referrals.
