ObjectiveAge-related macular degeneration (AMD) is one of the leading causes of low vision and blindness in people over 50 years old, and dry AMD (dAMD) is one type for which there is currently no clear treatment. On the basis of the diagnosis and clinical characteristics of dAMD in traditional Chinese and Western medicine, this paper evaluated the fitting degrees of existing animal models of dAMD with clinical characteristics according to the evaluation methods of animal models, and put forward suggestions and prospects. MethodsLiterature on animal models of dAMD was searched against database, and the characteristics of the models were assigned according to the diagnosis criteria of diseases and syndromes of traditional Chinese and Western medicine, and the fitting degrees of the models with clinical characteristics were analyzed and evaluated. ResultsAt present, the animal models of dAMD are mainly established targeting complement factors, chemokines, oxidative damage, lipid/glucose metabolism, and natural strains. Most of the models can simulate the major pathological changes of dAMD, showing the fitting degree of 25%-50% with clinical characteristics in Western medicine. However, the evaluation of traditional Chinese medicine (TCM) syndromes, especially the evaluation of secondary syndromes, is missing, and the models present low fitting degrees with the clinical characteristics in TCM. ConclusionExisting animal models of dAMD are mostly established under the guidance of Western diagnostic standards, which reproduce the main disease characteristics of Western medicine and lack observation of TCM syndromes. Future studies can pay attention to the intervention factors and evaluation systems of spleen deficiency Qi deficiency and liver-kidney Yin deficiency syndrome and build the animal model of dAMD with integration of disease and syndrome based on clinical characteristics of traditional Chinese and Western medicine.

ObjectiveRetinal vein occlusion (RVO) is the second most common vascular disease leading to vision loss. Since its pathogenesis remains unclear, current Western medical treatments primarily target complications such as macular edema and neovascularization. The main therapeutic approaches include intravitreal injections of anti-vascular endothelial growth factor (VEGF) agents or corticosteroids, laser photocoagulation, and pars plana vitrectomy. However, these treatments cannot fully reverse disease progression or structural damage. Traditional Chinese medicine (TCM) has unique advantages in the clinical diagnosis and treatment of RVO, and integrated Chinese and Western medicine approaches may offer better clinical outcomes. This study, based on the clinical manifestations of RVO, systematically reviews the existing literature and evaluates the alignment of current RVO animal models with clinical manifestations. The aim is to identify the characteristics and limitations of existing models and provide recommendations and prospects for developing RVO animal models featuring the combination of disease and syndrome. MethodsDatabases including CNKI, Wanfang Data, PubMed, and Web of Science were searched with the keywords of "retinal vein occlusion" and "animal model". Model characteristics were assessed based on the diagnostic criteria for diseases and syndromes in both TCM and Western medicine. The alignment of each model with clinical manifestations was analyzed and evaluated. ResultsThe available RVO models were primarily established via methods such as laser photocoagulation, photodynamic therapy, diathermy, intravitreal drug injection, and mechanical modeling. These models demonstrated moderate overall alignment with clinical manifestations, mainly reflecting disease characteristics. However, they generally lack representation of TCM syndrome features. ConclusionExisting RVO models are predominantly based on Western medicine and lack TCM syndrome features. Western medical treatments for RVO have certain limitations, while syndrome differentiation and treatment in TCM offer potential advantages. Future research should focus on developing disease-syndrome integrated animal models that incorporate both pathological features and TCM syndrome characteristics. This approach will enhance the design of RVO models and facilitate both basic and clinical research, which make it a scientifically valuable and necessary endeavor.

5.Advances in polymorphisms of genes associated with oxaliplatin-induced peripheral neurotoxicity
China Pharmacy 2026;37(1):130-136
Peripheral neurotoxicity represents one of the most severe dose-limiting adverse reactions associated with oxaliplatin, with genetic polymorphisms playing a significant role in oxaliplatin-induced peripheral neuropathy (OIPN). OIPN can be categorized as acute or chronic based on onset timing. The former presents clinically as sensory abnormalities or even motor disorders, while the latter presents clinically as limb sensory disorders that persist, numbness or pain in the hands and feet. The transporter genes OCT2, OCTN2, and NHE1 may be implicated in OIPN; drug-metabolizing enzyme gene GSTP1 Ile105Val, DPYD rs1801265, voltage-gated sodium channel (NaV) gene SCN4A rs2302237, SCN9A rs6746030, SCN10A rs12632942, and other associated genes such as HLA-G rs1610696, rs371194629 and CCNH rs2230641, rs3093816 are associated with severe OIPN. Conversely, DNA repair-related gene XRCC1 rs23885, NaV gene SCN9A rs3750904, rs12478318 and rs6754031 are associated with reduced OIPN risk. In the future, the genetic research findings on OIPN can be translated into clinical applications, ultimately achieving individualized precision medicine for patients.

Purpose To compare the similarity between the short-axis left ventricular cavity fractional area change measured by cardiac magnetic resonance and myocardial circumferential strain.Materials and Methods Forty cases of cardiomyopathy with different phenotypes and high-quality cardiac magnetic resonance images in PACS data center of the Sixth Medical Center of Chinese PLA General Hospital were retrospectively selected.All patients underwent cine imaging on a 3.0T MRI scanner.The endocardial and epicardial areas of each short-axis left ventricular slice were measured using Medviso Segment software to calculate slice-level fractional area change and global fractional area change.Slice circumferential strain and global circumferential strain were measured using Circle CVI42 software.Linear regression analysis was performed to assess correlations between global circumferential strain and global fractional area change,as well as slice circumferential strain and slice-level fractional area change.Results Both global circumferential strain and global fractional area change,as well as slice circumferential strain and slice-level fractional area change,exhibited positive correlations(all r>0.95).Linear regression demonstrated significant relationships(regression coefficients:2.40-3.16,P<0.05),with coefficient magnitudes related to left ventricular cavity radius.After normalization,circumferential strain and fractional area change curves showed identical standard deviations.Conclusion Short-axis left ventricular cavity fractional area change and myocardial circumferential strain display significant positive correlations at both slice and global levels,with similar curve morphology.These findings suggest that circumferential strain and fractional area change possess comparable statistical value in assessing cardiac function.

8.Progress of impaired memory suppression in patients with depressive disorders
Journal of Shanghai Jiaotong University(Medical Science) 2025;45(10):1378-1382
The intentional suppression of memory retrieval to achieve directed forgetting is a crucial adaptive function for individuals.In psychotherapy theory,such active forgetting is often associated with trauma,where in individuals actively exclude trauma-related negative memories from awareness to reduce unpleasant emotional experiences.Based on the"go/no-go"task paradigm,researchers developed the"think/no-think"(TNT)paradigm,and through this paradigm,they have revealed that individuals can achieve active forgetting by suppressing the retrieval of previously encoded memories.Patients with depressive disorders often exhibit cognitive processing biases toward negative information.Compared to healthy populations,they demonstrate impaired memory retrieval suppression in TNT tasks,especially for negative memories.This deficit in retrieval suppression makes negative memories more susceptible to reactivation,triggering negative emotions and perpetuating a vicious cycle.Relevant neuroimaging results show that during memory retrieval suppression,the lateral prefrontal lobe exerts top-down control through relevant regions to modulate memory processing of hippocampus,thereby blocking intentional recall.Abnormalities in the prefrontal-hippocampal inhibitory pathway and hyperactivation of the amygdala in depressed individuals may be the underlying neural mechanisms for their impaired suppression of negative memory retrieval.This article provides a review focusing on the negative memory bias exhibited in depressed individuals in the TNT task and the exploration of its underlying mechanisms.It summarizes relevant research findings with the aim of offering references for the development of precise psychotherapies and novel approaches targeting the improvement of specific symptom clusters.

Objective To evaluate the effect of optical body surface monitoring system(OSMS)in setup of intensity modulated radiotherapy(IMRT)for thoracic tumorsand to analyze its relationship with BMI.Methods Thesetup errors of CBCT and location CT with body membrane and the registration errors of OSMS and first body surface reference image without body membrane were obtained in 49 patients with thoracic tumor who received routine intensity modulated radiotherapy.The paired t-test was used to analyze the difference of registration errors between the two image guidance methods.Pearson′s correlation analysis was used to analyze the correlation between CBCT errors and OSMS errors,and Bland-Altman analysis was employed to evaluatethe agreement of the two errors.The correlation and consistency of the two registration errors in patients with different BMI index were analyzed.PTV external marginsby the two registration methods were calculated using Van Herk formula.Results The OSMS and CBCT groups demonstrated significant differences in setup errors in the ventrodorsal direction(P<0.05),while no significant differences were found in the left-right,head-foot translation directions,or RTN rota-tion directions(P>0.05).Although the two methods showed a significant correlation in setup errors(P<0.05),this correlation was only moderate in the head-foot and left-right directions(r=0.500,0.408),weak in the RTN rotation direction(r=0.339),and very weak in the ventrodorsal direction(r=0.152).The limits of agreement(LOA,95%CI)between the two methods were[-0.45,0.45]cm in the left-right direction,[-0.59,0.57]cm in the head-foot direction,and[-0.48,0.40]cm in the ventrodorsal direction,with(-2.08°~2.19°)in the RTN rotation direction.Different BMI levels influenced the results of the two registration methods,particularly in patients with a BMI of 18.5~23.9 kg/m2.In this group,OSMS and CBCT exhibited a strong correlation in the head-foot direction(r=0.731),a moderate correlation in the left-right direction(r=0.512),and weak correlations in the ventrodorsal and RTN rotation directions(r=0.345,0.267).The absolute difference in setup errors between the two imaging systems was 0.4~0.5 cm/2°.Using CBCT and OSMS image guidance,the margins in the left-right,head-foot,and ventrodorsal directions were[0.5 cm,0.7 cm,0.3 cm]for CBCT,and[0.5 cm,0.7 cm,0.5 cm]for OSMS.Conclusion In chest tumor patients with a BMI of 18.5~23.9 kg/m2,OSMS and CBCT image guidance methods show good correlation in the head-foot and left-right directions,but their limits of agreement exceed the clinically acceptable range.OSMS cannot yet replace CBCT for image guidance in chest tumor intensity-modulated radiotherapy.Further improvements to tumor motion surrogates are necessary to enhance the accuracy of OSMS image guidance.
