ObjectiveTo observe the clinical efficacy and safety of Tangning Tongluo tablets in the treatment of nonproliferative diabetic retinopathy （DR）. MethodsFourteen research centers participated in this study， which spanned a time interval from September 2021 to May 2023. A total of 240 patients with nonproliferative DR were included and randomly assigned into an observation group （120 cases） and a control group （120 cases）. The observation group was treated with Tangning Tongluo tablets， and the control group with calcium dobesilate capsules. Both groups were treated for 24 consecutive weeks. The vision， DR progression rate， retinal microhemangioma， hemorrhage area， exudation area， glycosylated hemoglobin （HbA1c） level， and TCM syndrome score were assessed before and after treatment， and the safety was observed. ResultsThe vision changed in both groups after treatment （P<0.05）， and the observation group showed higher best corrected visual acuity （BCVA） than the control group （P<0.05）. The DR progression was slow with similar rates in the two groups. The fundus hemorrhage area and exudation area did not change significantly after treatment in both groups， while the observation group outperformed the control group in reducing the fundus hemorrhage area and exudation area. There was no significant difference in the number of microhemangiomas between the two groups before treatment. After treatment， the number of microhemangiomas decreased in both the observation group （Z=-1.437， P<0.05） and the control group （Z=-2.238， P<0.05）， and it showed no significant difference between the two groups. As the treatment time prolonged， the number of microhemangiomas gradually decreased in both groups. There was no significant difference in the HbA1c level between the two groups before treatment. After treatment， the decline in the HbA1c level showed no significant difference between the two groups. The TCM syndrome score did not have a statistically significant difference between the two groups before treatment. After treatment， neither the TCM syndrome score nor the response rate had significant difference between the two groups. With the extension of the treatment time， both groups showed amelioration of TCM syndrome compared with the baseline. ConclusionTangning Tongluo tablets are safe and effective in the treatment of nonproliferative DR， being capable of improving vision and reducing hemorrhage and exudation in the fundus.

OBJECTIVE To evaluate the quality of evidence in the systematic evaluation/meta-analysis of traditional Chinese medicine （TCM） for diabetes retinopathy （DR） based on the GRADE system. METHODS Chinese and English databases were searched to obtain the relevant studies of systematic evaluation/meta-analysis of traditional Chinese medicine in the treatment of DR. The search time was from the establishment of each database to January 13th， 2024. According to the inclusion and exclusion criteria， literature screening was conducted. After extracting relevant information from the included literature， the GRADE system was used to evaluate the quality level of the evidence body in the included studies， and the evidence of the outcome indicators was integrated and summarized. RESULTS A total of 51 studies were ultimately included， encompassing 135 outcome indexes. Among these， 19 indicators （14.1%） were of high quality， 87 （64.4%） were of medium quality， 26 （19.3%） were of low quality， and 3 （2.2%） were of very low quality. Overall， the evidence quality of the outcome indicators in the included studies was medium to low quality. The integrated results of evidence on the efficacy of outcome indexes showed that compared with conventional Western medicine， calcium dobesilate or placebo， TCM had significant advantages in improving overall efficacy， reducing bleeding spot area， reducing macular foveal thickness， and increasing visual improvement rate. In addition，the combination of TCM and conventional Western medicine or calcium dobesilate was significantly more effective than using conventional Western medicine or calcium dobesilate alone. CONCLUSIONS The overall quality of the evidence in the systematic evaluation/meta-analysis study on the treatment of DR with TCM is medium to low quality. Based on existing research findings， TCM demonstrates good clinical efficacy in the treatment of DR.

AIM: To conduct a CiteSpace-based visualization analysis of the literature on traditional Chinese medicine(TCM)treatment of diabetic retinopathy(DR)from January 2014 to January 2024.METHODS: The literatures were retrieved from the China National Knowledge Infrastructure(CNKI)database. Co-occurrence, clustering, and emergence analyses of annual publications, authors, research institutions, and keywords were performed using Note Express and CiteSpace software to generate knowledge graph.RESULTS: A total of 643 Chinese-language articles were included. The annual publication trend was characterized by fluctuations. The primary research institutions were Liaoning University of Traditional Chinese Medical and Eye Hospital China Academy of Chinese Medical Sciences. Twenty high-frequency keywords were identified, including diabetes, TCM, and review, along with emergent terms such as Qiming granules and data mining. The research focus in 2014 was on exploring therapeutic methods and the efficacy of proprietary Chinese medicines. From 2016 to 2018, the research perspective expanded to include symptoms and multi-factorial analysis. Between 2018 and 2020, there was an in-depth investigation into evidence types and disease stages. After 2019, the emphasis shifted towards TCM-specific therapies and patient-centered concepts. From 2022 to 2024, innovation in research methods and the theory of TCM collaterals theory emerged as new hotspots.CONCLUSION: The research on TCM treatment for DR is still in an ascending phase. The primary research hotspot currently centers on Qiming granules. Future trends are likely to focus on the efficacy and mechanisms of action. The combined application of different therapies and long-term follow-up experimental research could provide a more robust basis for evidence-based medicine, unearth the potential of TCM, and promote its development in the prevention and treatment of DR.

Objective This study aims to systematically evaluate the evidence-based medicine of traditional Chinese medicine(TCM)in the treatment of dry eye,analyze its efficacy and differences compared with modern Western medicine treatments,and provide a scientific basis for clinical application.Methods By searching Chinese and English databases(including CNKI,Wanfang Data,PubMed,Cochrane Library,etc.),we included meta-analyses and systematic reviews of TCM treatments for dry eye.Literature was screened according to strict inclusion and exclusion criteria,and relevant data were extracted and integrated for analysis.The Mantel-Haenszel fixed-effects model was used to calculate the relative risk(RR)and mean difference(WMD),with the effect size expressed as a 95％confidence interval,to analyze the efficacy in-dicators of TCM treatment for dry eye.Results A total of 21 articles were finally included,involving various TCM inter-ventions for dry eye(such as Chinese herbal medicine,acupuncture,and TCM external therapies).The results showed that TCM treatment was superior to Western medicine alone in improving the overall clinical efficacy[RR=1.63,95％CI(1.46,1.81),P＜0.05],prolonging tear film break-up time[MD=2.23,95％CI(1.85,2.60),P＜0.05],and increasing tear secretion[MD=1.49,95％CI(1.04,1.94),P＜0.05].In addition,acupuncture,the combination of Chinese herbal medicine and Western medicine,and TCM external therapies all demonstrated unique advantages in improving dry eye symptoms and tear function.Conclusion TCM treatment for dry eye shows significant efficacy in key indicators such as overall clinical efficacy,tear film break-up time,and tear secretion,with a high level of safety.

Focal choroidal excavation(FCE)is an elusive clinical sign characterized by a localized structural depression in the choroid. It has been increasingly recognized with the widespread use of optical coherence tomography(OCT), though its pathogenesis remains incompletely understood and may involve congenital developmental anomalies or acquired factors(such as inflammation or tumor compression). Studies indicate that FCE can occur independently or secondary to various chorioretinal diseases(e.g., central serous chorioretinopathy, choroidal osteoma, age-related macular degeneration, etc.). Clinically, it has also been observed that FCE may be associated with the development of choroidal neovascularization(CNV). Potential mechanisms linking FCE and CNV include: 1)mechanical traction-hypoxia-signaling pathway activation; 2)disruption of the retinal pigment epithelium(RPE)-Bruch's membrane-choroid complex barrier; 3)structural collapse induced by inflammatory scar contraction. Anti-vascular endothelial growth factor(VEGF)therapy is currently the mainstay of treatment for CNV secondary to FCE. By reviewing relevant domestic and international literature, this paper seeks to elucidate the possible pathological relationship between FCE and CNV, with the goal of facilitating early identification of high-risk patients and optimizing anti-VEGF treatment strategies. It also highlights the limitations of current research(such as sample heterogeneity and lack of histological validation of typing criteria), and suggests future directions, such as multicenter studies and molecular mechanism investigations, to support the development of personalized diagnostic and therapeutic approaches.

Diabetic retinopathy(DR)is one of the common serious microvascular complications in diabetic patients,with the main pathological features of retinal vascular injury,oxidative stress and chronic inflammatory re-sponse.In recent years,more and more studies have shown that mitophagy plays an important role in maintaining the func-tional homeostasis of retinal cells and preventing oxidative damage,and nucleotide-binding oligomerization domain-like re-ceptor protein 3(NLRP3)is a key regulator of pro-inflammatory response in DR.Mitophagy can reduce the excessive pro-duction of reactive oxygen species(ROS)by removing damaged mitochondria,thereby inhibiting the activation of NLRP3 inflammasome.In contrast,mitochondrial dysfunction can lead to excessive activation of NLRP3 inflammasome,which further aggravates the inflammatory response and apoptosis of the retina.Therefore,this article reviews the independent role of mitophagy and NLRP3 inflammasome in DR and their mutual regulatory mechanisms,so as to provide reference for the study of mitophagy and NLRP3 inflammasome as targets.
