Diabetic kidney disease（DKD） is a chronic kidney structural and functional disorder caused by diabetes. With the global prevalence of diabetes continuing to rise， DKD has gradually become a major cause of chronic kidney disease and end-stage renal disease（ESRD）， posing a serious threat to patients' quality of life and long-term health outcomes. Studies have shown that apoptosis plays a pivotal role in the development and progression of DKD， with its mechanisms involving abnormal activation of multiple signaling pathways such as Toll-like receptor 4（TLR4）/nuclear transcription factor-κB（NF-κB）/B-cell lymphoma-2（Bcl-2）/cysteinyl aspartate-specific proteinase（Caspase）-3， protein kinase R-like endoplasmic reticulum kinase（PERK）/eukaryotic initiation factor 2α（eIF2α）/activating transcript factor 4（ATF4）/CCAAT enhancer-binding protein homologous protein（CHOP）， phosphatidylinositol 3-kinase（PI3K）/protein kinase B（Akt）/glycogen synthase kinase-3β（GSK-3β）， Janus kinase 2（JAK2）/signal transducer and activator of transcription 3（STAT3）， adenosine monophosphate-activated protein kinase（AMPK）/mammalian target of rapamycin（mTOR） and silent information regulator 1（SIRT1）/tumor suppressor protein 53（p53）， thereby accelerating renal pathological damage in DKD. Extensive evidence-based medical studies have confirmed that traditional Chinese medicine（TCM）， leveraging its unique therapeutic advantages of multi-target， multi-component and multi-pathway approaches， has demonstrated remarkable efficacy and favorable safety profiles in treating DKD. Recent studies have demonstrated that active components of TCM can specifically target and modulate key effectors in apoptotic signaling pathways. Meanwhile， traditional compound formulations exert synergistic effects through multiple approaches such as replenishing deficiency and activating blood circulation， detoxifying and dredging collaterals， tonifying kidney essence， and removing stasis and purging turbidity， thereby comprehensively regulating critical pathological processes including endoplasmic reticulum stress and mitochondrial apoptosis pathways. This combined therapeutic approach of molecular targeting and holistic regulation provides novel strategies for delaying the progression of DKD. Based on this， this paper provides an in-depth analysis of key apoptotic signaling pathways and their regulatory mechanisms， while systematically summarizing recent research advances regarding the therapeutic effects of TCM active components， compound formulations， and proprietary Chinese medicines on DKD through modulation of these pathways， with particular emphasis on their underlying molecular mechanisms. These findings not only elucidate the modern scientific connotation and theoretical basis of TCM in treating DKD but also establish a solid theoretical and practical foundation for promoting the wider clinical application and further research of TCM in the field of DKD treatment.

ObjectiveThis paper aims to systematically summarize the construction methods and characteristics of Alzheimer's disease （AD） animal models， providing a reference for improving AD animal models. MethodsLiterature related to AD animal models published between January 2022 and April 2025 was retrieved from China National Knowledge Infrastructure （CNKI）， China Biomedical Literature Database （CBM）， Wanfang Data， and VIP Database. Information such as experimental animal species， month of age， sex， modeling methods， and period， as well as evaluation indicators， was collated， extracted， and imported into Microsoft Excel 2024 to establish the database. In addition， various modeling methods and detection means were summarized and compared. ResultsA total of 400 articles were included. Among the AD animal models， amyloid precursor protein/presenilin-1 （APP/PS1） mice were used most frequently， with a predominance of male animals. Typically， 3-4-month-old rats or 5-6-month-old mice were selected. The main modeling methods included natural aging， accelerated aging， surgical intervention， drug induction， and transgenic technology. The modeling period was mainly concentrated in a single day or 6-8 weeks. Detection indicators of the models focused on physiological， behavioral， pathological-morphological， and biochemical phenotypes. ConclusionThe construction methods of AD animal models are relatively mature， with multifactorial interventions effectively simulating human pathology， though certain limitations remain. By systematically reviewing and analyzing recent experimental literature of AD animal models， this study aims to provide theoretical support and a reference for further improving the construction of the AD animal model.

Objective: To examine the association between parent-child communication frequency about school related matters and depressive symptom risk among children and adolescents and to characterize its dose response pattern, so as to provide a reference for family intervention and school mental health promotion. Methods: Data were obtained from the 2022 China Family Panel Studies(CFPS), conducted from May to December 2022. A total of 1 896 children and adolescents aged 10-15 years were included. The 8 item Center for Epidemiologic Studies Depression Scale (CES-D8) was adopted to assess depressive symptoms among children and adolescents. Data on the parent-child communication frequency about school related matters was obtained from CFPS Child Proxy Questionnaire. Multivariable Logistic regression, sensitivity analyses, and exploratory segmented regression were performed. Results: A total of 375 participants were screened positive for depressive symptoms, with a prevalence of 19.8%. The prevalence decreased from 23.3% in the "never" group to 10.6% in the "very often" group ( χ 2=19.30, P <0.05). In the fully adjusted model, the point estimate for the "very often" group suggested lower odds of a positive screen ( OR =0.52), and the test for trend was statistically significant ( P =0.03). The association was more pronounced among children aged 10-12 years ( OR=0.31, 95%CI=0.11-0.86, P <0.05). Sensitivity analyses yielded directionally consistent results, but the statistical evidence was weakened ( OR=0.83, P trend =0.08). Dose response analysis showed a statistically significant overall association between parent-child communication frequency about school related matters and depressive symptom risk ( P =0.04), with no significant departure from linearity ( P = 0.14 ). Among the prespecified cut points, exploratory segmented regression showed relatively better model fit at an ordinal frequency score of 4.5, between "often" and "very often" (likelihood ratio test P =0.03). However, the overall test for nonlinearity was not statistically significant ( P =0.14), and the finding should therefore be interpreted as exploratory. Conclusion More frequent parent-child communication about school related matters is associated with lower depressive symptom risk, suggesting that routine communication about such matters may help reduce the risk of depressive symptoms in children and adolescents.

Starting from the intrinsic relationship between the glymphatic system and the core pathogenesis of vascular cognitive impairment （VCI）， including internal dampness， phlegm turbidity， and blood stasis， this paper explores clinical approaches to the diagnosis and treatment of VCI. Dysfunction of the kidney's role in governing water leads to the accumulation of dampness， phlegm turbidity， and blood stasis， which are key pathological mechanisms underlying the onset and progression of VCI. The glymphatic system participates in the circulation of cerebrospinal fluid within the central nervous system， and its impairment can result in reduced clearance of soluble metabolic waste products in the brain， a crucial factor contributing to VCI. It is proposed that the "kidney governing water" function is related to the glymphatic system， and that the cerebral collaterals correspond structurally to the glymphatic pathways. Clinically， therapies aimed at tonifying the kidney， resolving phlegm， activating blood circulation， and unblocking collaterals， such as modified Kaixin Powder （开心散）， which eliminates dampness and turbidity， transforms phlegm， restores consciousness， enhances cognition， and strengthens the brain， are commonly employed. These treatments may improve VCI prognosis by regulating glymphatic system function， providing a theoretical basis for the prevention and treatment of VCI with traditional Chinese medicine.

Objective:To reveal the coupling mechanism of beam temporal profile and tissue oxygen content on radical kinetics, further explain the potential biological basis of the FLASH effect, and provide a reference for beam optimization and treatment planning design of FLASH radiotherapy (FLASH-RT).Methods:TOPAS-nBio v3.0 was used to simulate the physical and chemical processes of electron beams in water, and a full-scale kinetic model was established covering the generation, diffusion, reaction, and quenching of free radicals such as hydroxyl radical (·OH) and hydrated electrons (e aq-). Under different beam temporal profiles (single pulse, multi-pulses, continuous wave irradiation) and different oxygen concentration conditions, the evolution dynamics of free radicals were systematically simulated. At the same time, the data on e aq- content were obtained by experimental measurement of laser absorption spectroscopy to verify the accuracy of the model prediction. Results:The changing trend of e aq- concentration measured in the experiment was highly consistent with the simulation result, verifying the reliability of the constructed model. The beam time structure had a significant impact on the peak value and duration of free radical concentration. The single-pulse structure can cause the free radicals to rapidly increase and then quickly quench in a short time, while the continuous or long-pulse structure can cause the radical concentration to remain at a high level for a long time. The evolution of ·OH was not sensitive to the oxygen environment, while e aq- are greatly affected by the oxygen environment. The scavenging efficiency of free radicals in a hypoxic environment was significantly decreased, leading to an enhanced accumulation of oxidative damage to biological macromolecules. The lifespan of e aq- in an oxygen-rich environment decreased rapidly. Conclusions:Radical kinetics are regulated by both the beam temporal profile and oxygen content. FLASH-RT can utilize single-pulse or multi-pulses intervals to form periodic windows, reducing normal tissue damage by efficiently scavenging free radicals through antioxidants, while free radicals in tumor tissues continuously accumulate and amplify damage, thus generating a selective protective effect.
