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.

ObjectiveTo investigate the mechanism by which Luoshi Neiyi prescription treats endometriosis （EMs） through the Toll-like receptor 4 （TLR4）/nuclear factor-κB （NF-κB） signaling pathway. MethodsAnimal experiments were conducted with 50 female SD rats， which were randomized into a sham operation group （10 rats） and a modeling group （40 rats）. An autologous endometrial transplantation method was used for the modeling of EMs. The 36 successfully modeled rats were randomly allocated into four groups （n=9 each）： The model group， the low-dose （7.87 g·kg^-1） Luoshi Neiyi prescription group， the high-dose （15.74 g·kg^-1） Luoshi Neiyi prescription group， and the dienogest （0.20 mg·kg^-1） group. The physiological status and ectopic lesion volumes of rats in each group were observed. Hematoxylin-eosin （HE） staining was used to observe the morphology of the eutopic endometrial tissue. Enzyme-linked immunosorbent assay （ELISA） was employed to measure the levels of inflammatory factors including interleukin-1β （IL-1β） and prostaglandin E₂ （PGE₂） in the serum of EMs rats. Immunohistochemistry was used to detect the expression of matrix metalloproteinase-9 （MMP-9） and vascular endothelial growth factor A （VEGFA） in the eutopic endometrial tissue. Western blot was adopted to determine the protein levels of TLR4， myeloid differentiation factor 88 （MyD88）， phosphorylated nuclear factor-κB （p-NF-κB）/NF-κB， MMP-9， and VEGFA in the eutopic endometrial tissue. In the cell experiments， the cell-counting kit-8 （CCK-8） assay was employed to screen the optimal concentration of Luoshi Neiyi prescription-containing serum， and a scratch assay was performed to assess the migration ability of iheESCs cells. Interventions with Luoshi Neiyi prescription-containing serum， resatorvid （TAK-242， a TLR4 inhibitor）， and lipopolysaccharides （LPS， a TLR4 agonist） were conducted， and Western blot was used to detect the expression of proteins related to the TLR4/NF-κB signaling pathway. ResultsThis experiment successfully replicated 36 EMs rat models. Compared with the sham operation group， the model group exhibited visible ectopic lesions on the abdominal wall and an increase in the writhing response score （P<0.01）. Furthermore， HE staining revealed the model group exhibited a thickened eutopic epithelium， stromal cell disarrangement， and evident infiltration of inflammatory cells. In addition， the model group showed elevated serum levels of IL-1β and PGE₂ （P<0.05， P<0.01）， increased positive expression of MMP-9 and VEGFA in the ectopic endometrial tissue （P<0.01）， and up-regulated protein levels of TLR4， MyD88， p-NF-κB/NF-κB， MMP-9， and VEGFA in the ectopic endometrial tissue （P<0.05， P<0.01）. Compared with the model group， all treatment groups exhibited a reduction in the ectopic lesion volume （P<0.01）. Furthermore， the writhing response scores were decreased in the high-dose Luoshi Neiyi prescription group and the dienogest group （P<0.05， P<0.01）. The pathological state of the ectopic endometrial tissue was alleviated to varying degrees in the treatment groups. Low-dose Luoshi Neiyi prescription reduced serum PGE₂ levels， and high-dose Luoshi Neiyi prescription and dienogest decreased serum IL-1β and PGE₂ levels in EMs rats （P<0.05， P<0.01）. The treatment groups showed decreased positive expression of MMP-9 and VEGFA in the ectopic endometrial tissue （P<0.05， P<0.01） and down-regulated protein levels of TLR4， MyD88， p-NF-κB/NF-κB， MMP-9， and VEGFA in the ectopic endometrial tissue （P<0.05， P<0.01）. The cell experiments showed that 5%， 10%， and 20% Luoshi Neiyi prescription-containing sera significantly reduced the viability and inhibited the migration of iheESCs. Compared with the control group， 5%， 10%， and 20% Luoshi Neiyi prescription-containing serum groups and the TAK-242 group showed reduced protein levels of TLR4， MyD88， p-NF-κB/NF-κB， MMP-9， and VEGFA （P<0.01）. Compared with the control group， the LPS group showed increased expression of the above proteins （P<0.01）. Compared with the LPS group， the LPS+5%， 10%， and 20% Luoshi Neiyi prescription-containing serum groups showed reduced expression of the above proteins （P<0.05， P<0.01）. ConclusionLuoshi Neiyi prescription may modulate the TLR4/NF-κB signaling pathway to reduce the inflammatory response and histopathological damage in the eutopic endometrium and suppress the adhesive， invasive， and angiogenic biological processes in the ectopic endometrial tissue， thereby exerting its therapeutic effect on EMs.

Objective We reviewed and analyzed the epidemiological data of 83 imported dengue fever cases reported in Fengtai District, Beijing, from 2007 to 2025, to delineate their epidemiological characteristics and guide the dengue fever prevention and control strategy in the future. Methods Data on dengue fever cases in Fengtai District from 2007 to 2025 were collected to identify the epidemic factors and characteristics using descriptive epidemiological method. Results All 83 dengue fever cases reported in this region over the past two decades have been imported from abroad or other domestic areas, with Southeast Asian countries being identified as the primary source of imported infections, accounting for 42 cases (50.60%), followed by 15 cases (18.07%) from Chinese provinces other than Beijing. The remaining import sources included 13 cases from South Asia,8 from African countries, and each from Oceania, South America, and Europe. Disease onset was found concentrated between May and November. The sex ratio (male-to-female) is 1.59:1. The age of onset ranged from 14 to 61 years old, with a median age of 36. The largest proportion of cases was observed among cadres and office workers (31 cases, 37.35%), followed by businessmen (13 cases, 15.67%), and householders or the unemployed (10 cases,12.05%). Travel visit was identified as the primary reason for their exposure history. Conclusions All dengue fever cases reported in Fengtai from 2007 to 2025 were imported, with an increasing trend of imported cases in Beijing originating from other Chinese provinces. It is essential to strengthen health education for foreign travelers and returning residents, enhance clinical diagnosis and treatment training for medical personnel, eliminate mosquito breeding sites, and reduce mosquito density through active patriotic health campaigns.

Objective:To collect registered clinical research plans on TCM characteristic therapies for treating cervical spondylosis; To explore their research registration status; To provide references for future clinical trial registration and implementation.Methods:Clinical research on TCM characteristic therapies for treating cervical spondylosis was retrieved from ChiCTR, ITMCTR and Clinical Trials. gov from the establishment of the databases to July 1, 2024. Excel 2019 was used to conduct descriptive statistics on registration time, registration area and institution, funding source, research type and design scheme, research participation center and sample size, cervical spondylosis type, intervention measures, outcome indicators, reporting quality, research openness and methodological application.Results:A total of 138 clinical trials for the TCM treatment of cervical spondylosis were included, of which 136 were registered by domestic researchers in 22 provincial-level administrative regions. The top three in terms of registration numbers were Shanghai, Guangdong Province, and Beijing. Additionally, 2 were registered by foreign researchers in Egypt and Malaysia. The main sources of funding were 50 local finances, followed by 26 hospital subsidies and 18 national finances. The intervention research accounted for the largest proportion of research types, with 123 items (89.13%). The research center mainly focused on single center studies (98 projects). Most randomized controlled trials (115 trials) described randomization methods, while a small number of randomized controlled trials (50 trials) indicated blinding. The intervention measures were mostly combined with TCM therapy, and the outcome indicators were mainly efficacy indicators, with fewer safety indicators.Conclusions:At present, clinical trial registrations for TCM treatment of cervical spondylosis are increasing, but issues remain, such as poor study design, uneven distribution, and incomplete information. It is recommended to refine registration details, optimize study protocols, and promote high-quality clinical research.

Objective To summarize the clinicopathological characteristics,diagnostic and therapeutic process and aeromedical evaluation of 17 cases of thyroid cancer in Chinese military pilots in order to provide a reference for the diagnosis and treatment of disease and aeromedical evaluation of patients with thyroid cancer in military pilots in the future.Methods A retrospective analysis was conducted on the clinicopathological characteristics,treatment methods and aerospace medical evaluation conclusions of 17 military pilots with thyroid cancer who were hospitalized and underwent diagnosis,treatment and aeromedical evaluation at the Department of Aviation Medicine of Xijing Hospital from March 2021 to March 2025.Results All 17 pilots with thyroid cancer were male,and the age of onset ranged from 22 to 51 years old(with a median age of 40 years old).All patients underwent fine-needle aspiration biopsy of thyroid nodules or enlarged cervical lymph nodes before the operation.The postoperative pathological types were all papillary thyroid carcinoma.Among them,16 cases were papillary thyroid microcarcinoma,9 cases were combined with regional lymph node metastasis,and 1 case with postoperative complications of Horner's syndrome recovered after treatmentwas.14 patients underwent unilateral glandular lobe and isthectomy of the thyroid,3 patients underwent total/near-total thyroidectomy,2 patients received radioactive 131I treatment after the operation,and 17 patients received thyroid stimulating hormone(TSH)suppression therapy after the operation.After aerospace medical evaluation,15 cases were qualified for flight duties,the observation time was 3 to 6 months(with an average observation time of 4.2 months),1 case reached the age limit,and 1 case was temporarily unqualified for failure to achieve TSH suppression.After 0.5 to 4.0 years of follow-up,no patient showed signs of recurrence or metastasis.Conclusion For thyroid cancer in military pilots,universal screeningprotocols and earlydetection,as well as standardized therapeutic regimensshould be carried out.Evidence-based aeromedical evaluations and long-term monitoring should be conducted based on the aircraft type,jobs,and flight experience to preserve military combat effectiveness to the greatest extent.

Objective:To investigate the value of nomogram model based on CT features in differentiating ectopic pancreas (EP) from gastrointestinal stromal tumors (GIST) with a long diameter less than 3 cm.Methods:This study was a case-control study. The clinical and imaging data of 43 patients with EP and 90 patients with GIST confirmed by pathology in the Affiliated Hospital of Guizhou Medical University from August 2013 to March 2024 were retrospectively analyzed. Preoperative CT images were analyzed to obtain qualitative features (number of lesions, location, morphology, growth pattern, borders, cystic degeneration, calcification, ulceration, catheter sign, central umbilication) and quantitative features (lesion long diameter, short diameter, long/short diameter, lesion and normal pancreas arterial-phase and venous-phase CT values, and enhancement ratio). Statistical analyses, including independent sample t-tests, Mann-Whitney U tests, χ2 tests, and Fisher exact tests, were performed to compare CT characteristics between the two groups. Binary logistic regression analysis was used to obtain independent predictors to identify the two groups, to establish a joint model, and to draw a nomogram. The discriminative performance of the independent predictors and the combined model was assessed using receiver operating characteristic (ROC) curves, while calibration curves were used to evaluate model fit. Results:The differences in age, location, morphology, border, catheter sign, central umbilication, short diameter, long/short diameter, arteriovenous phase enhancement CT value and arteriovenous phase enhancement ratio were statistically significant between the EP group and the GIST group (all P<0.05). The logistic analysis showed that the differences in age ( OR=0.920, 95% CI 0.885-0.956, P<0.001), border ( OR=5.994, 95% CI 2.111-17.022, P=0.001), long/short diameter ( OR=7.820, 95% CI 1.841-33.224, P=0.005), and venous phase enhancement ratio ( OR=8.847, 95% CI 1.103-70.972, P=0.040) were the independent predictors for distinguishing EP from GIST, and the area under the ROC curve (AUC) were 0.782 (95% CI 0.698-0.866), 0.684 (95% CI 0.600-0.767), 0.705 (95% CI 0.607-0.803), and 0.693 (95% CI 0.605-0.781), respectively. Combined age, border, long diameter/short diameter and venous phase enhancement ratio were plotted in a nomogram with an AUC of 0.881 (95% CI 0.817-0.945), sensitivity and specificity of 74.4% and 93.3%, respectively. The calibration curve demonstrated a strong agreement between predicted and actual probabilities (Hosmer-Lemeschow test, P=0.267). Conclusions:CT imaging reveals significant differences between EP and small GISTs (<3 cm). EP is more likely when patients are younger and lesions exhibit indistinct borders, a higher long-to-short diameter ratio, and greater venous-phase enhancement. The nomogram derived from CT features provides a valuable tool for differentiating EP from GIST.

AIM:Regulatory T cells(Tregs)are a specialized subset of CD4+T cells primarily involved in im-munosuppressive functions.AMP-activated protein kinase(AMPK)serves as a metabolic sensor that governs the differen-tiation,maturation,and immune functions of Tregs through metabolic reprogramming.However,the impact of AMPKα1(the catalytic subunit of AMPK)knockout specifically in Tregs on the host's immune microenvironment remains largely un-explored.METHODS:Histological changes in immune organs were assessed using HE staining.The types of immune cells and their relative population percentages in immune organs and blood were quantified through flow cytometry in both AMPKα1flox/flox(AMPKα1fl/fl)mice and Treg-specific AMPKα1 knockout mice(AMPKα1fl/flFoxp3cre mice).RESULTS:Compared to AMPKα1fl/fl mice,the percentage of eosinophils in the bone marrow of AMPKα1fl/flFoxp3cre mice was significant-ly reduced.Additionally,while the thymus of AMPKα1fl/flFoxp3cre mice exhibited normal structure,both its size and the ra-tio of thymus weight to body weight were significantly decreased.The knockout of AMPKα1 in Tregs led to a notable reduc-tion in the total percentage of immature double-negative(DN)cells.Consequently,the percentage of CD4+T cells derived from these DN cells also decreased,even though the percentages of DN1 and DN4 cells were higher in the thymus of AMPKα1fl/flFoxp3cre mice compared to AMPKα1fl/fl mice.Importantly,the proportion of Siglec-F+CD11b+eosinophils in the thymus was significantly lower in AMPKα1fl/flFoxp3cre mice.Knockout of AMPKα1 in Tregs resulted in a marked increase in the percentage of CD4+T cells in peripheral blood,alongside a decrease in the proportion of mature CD8+T cells.Similar-ly,the proportion of CD4+T cells in the spleen of AMPKα1fl/flFoxp3cre mice was elevated compared to AMPKα1fl/fl mice.In contrast,the proportion of neutrophils significantly decreased,while mononuclear cell proportions increased in the spleen of AMPKα1fl/flFoxp3cre mice.In lymph nodes,the medullary boundaries in AMPKα1fl/flFoxp3cre mice were blurred,and the lymphoid follicles were missing,a feature not observed in AMPKα1fl/fl mice.Furthermore,the knockout of AMPKα1 in Tregs reduced the CD3+T cell population,particularly the CD8+T cell population,in lymph nodes.Although the mature Treg cell population was significantly lower in AMPKα1fl/flFoxp3cre mice,the percentage of CD4+T cells was markedly in-creased.In contrast,there was no statistically significant difference in granulocyte populations between AMPKα1fl/flFoxp3cre and AMPKα1fl/fl mice.CONCLUSION:The populations of mature Tregs,CD8+T cells and eosinophils in various im-mune organs were significantly altered in mice with Treg-specific AMPKα1 knockout,suggesting a potential remodeling of the host immune microenvironment in response to inflammatory stimuli.
