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.

The hypothalamic-pituitary-gonadal (HPG) axis is the central neuroendocrine regulator of vertebrate reproduction, governing sexual maturation, reproductive function, and endocrine homeostasis through multilevel hormonal cascades. It is also a sensitive target for environmental endocrine disruptors. Hypothalamic gonadotropin-releasing hormone (GnRH) neurons and pituitary gonadotropes are located upstream of the HPG axis, and are indispensable for reproductive and endocrine functions. Agrochemicals represent a major class of endocrine-disrupting chemicals capable of interfering with GnRH pulsatility as well as the synthesis and release of gonadotropins through multiple pathways. This review summarized recent epidemiological and toxicological evidence concerning the effects of insecticides, herbicides, fungicides and plant growth regulators on hypothalamic GnRH neuron-pituitary gonadotropes. It surveyed the evidence linking agrochemicals exposure to abnormalities in hypothalamic GnRH pulsatility and disturbances in gonadotropin synthesis and secretion, and further examined the roles of key pathways such as the Kisspeptin/G protein-coupled receptor 54 system, neurotransmitters and signaling molecules, ion channels, as well as oxidative stress and inflammatory responses. Current research remains largely confined to insecticides, with significant limitations in simulating real-world exposure complexity and systematically elucidating underlying toxic mechanisms. Future studies should expand to other agrochemicals classes and integrate emerging approaches such as multi-omics and computational toxicology to systematically identify the integrated mechanisms disrupting upstream HPG axis functions. Such efforts will provide more comprehensive scientific evidence for assessing the reproductive toxicity of agrochemicals.

Objective To introduce the calculation of the DISO index in multi-dimensional data ranking for disease surveillance, and evaluate its applicability. Methods Using the data from the quality supervision and inspection of infectious disease reporting in Jingzhou City in a certain year as an example, the DISO index was used to rank 16 investigated medical institutions and compared with the TOPSIS method. The consistency between the two evaluation results was analyzed using Spearman correlation. Then, The DISO index from different medical institutions was used to evaluate the ranking of 8 counties (cities, districts). The evaluation indicators for the supervision and inspection included six items: report rate, timely report rate, completeness of report card filling, accuracy of report card filling, consistency rate with network information report, and completeness of valid ID number filling. Results Among the 16 medical institutions, 8 institutions had all six evaluation indicators at 100%. Using the two methods to rank the 16 medical institutions, the two methods showed that the 8 medical institutions with all six evaluation indicators at 100% were ranked first. There was a strong correlation between the rankings of the 16 medical institutions using the two methods (r_s=0.992, P=0.000). The three counties (cities, districts) with all six evaluation indicators at 100% were all ranked first, while country G was ranked seventh and country E was ranked eighth. Conclusion The results of the DISO index and the TOPSIS method were similar in one-dimensional ranking. DISO can be used for multi-dimensional ranking of disease surveillance data and deserves to be promoted and applied.

MethodsA single-center， randomized， parallel-controlled clinical trial was conducted. A total of 78 patients diagnosed with stage G3A3 DKD and traditional Chinese medicine （TCM） pattern of Qi-Yin deficiency combined with dampness-heat and blood stasis and treated in the Department of Nephrology and the Department of Endocrinology of the People's Hospital Affiliated to Fujian University of Traditional Chinese Medicine from March 2025 to February 2026 were enrolled. They were randomly assigned at a 1∶1 ratio into a control group （conventional Western medicine treatment） and an experimental group （Yishen Jiangtang decoction combined with conventional Western medicine treatment）， with 39 patients in each group. The treatment lasted for 12 weeks. Basic demographic data and medical history were collected before and after treatment. The two groups before and after treatment were compared in terms of the following parameters： Blood urea nitrogen （BUN）， serum creatinine （SCr）， estimated glomerular filtration rate （eGFR）， urinary albumin-to-creatinine ratio （UACR）， fasting blood glucose （FBG）， triglycerides （TG）， total cholesterol （TC）， and low-density lipoprotein cholesterol （LDL-C）. Enzyme-linked immunosorbent assay （ELISA） kits were used to measure serum glucose-regulated protein 78 （GRP78）， serum cysteinyl aspartate-specific protease-3 （Caspase-3）， and serum and urinary transforming growth factor-β₁ （TGF-β₁） levels before and after treatment. TCM symptom scores， TCM syndrome efficacy， and overall clinical efficacy were evaluated before and after treatment. Spearman correlation analysis was performed to explore the correlations of serum levels of GRP78 and Caspase-3， as well as serum and urinary levels of TGF-β1， with renal function， proteinuria， and glucose and lipid metabolism indicators in patients with DKD. In addition， safety indicators were also monitored. ResultsA total of 75 patients completed the study （38 in the control group and 37 in the experimental group）. ① Baseline data： The two groups were comparable in terms of sex and age， with no statistically significant difference. ② Efficacy outcomes： Compared with baseline levels， both groups showed reductions in BUN， SCr， UACR， FBG， TG， TC， LDL-C， and TCM symptom scores （P<0.01） and increases in eGFR level （P<0.01）. Moreover， the experimental group outperformed the control group in altering the indicators above （P<0.05）. Regarding TCM syndrome efficacy， the total response rate in the experimental group was 83.78%， which was higher than that （57.89%） in the control group （P<0.05）. Regarding overall clinical efficacy， the total response rate in the experimental group was 78.38%， which was higher than that （50.00%） in the control group （P<0.05）. ③ Mechanism outcomes： Compared with baseline levels， both groups showed declined serum levels of GRP78， Caspase-3， and TGF-β₁ and urinary level of TGF-β₁ after treatment （P<0.01）. Moreover， the experimental group showed greater declines than the control group （P<0.05）. The serum levels of GRP78， Caspase-3，and TGF-β₁ and the urinary level of TGF-β₁ in DKD patients showed positive correlations with BUN， SCr， UACR， and FBG and negative correlations with eGFR （P<0.05）. ④ Safety outcomes： Neither group showed drug-related adverse reactions， and laboratory safety parameters remained within normal ranges. ConclusionYishen Jiangtang decoction combined with conventional Western medicine treatment may safely and effectively alleviate clinical symptoms， correct glucose and lipid metabolism disorders， and protect the renal function in patients with stage G3A3 DKD and the pattern of Qi-Yin deficiency combined with dampness-heat and blood stasis. The mechanism may be associated with inhibition of the ERS-apoptosis axis and delay of the RF process.

BACKGROUND:With the increase of age,the function of bone marrow-derived mesenchymal stem cells is gradually reduced,and delaying the aging of bone marrow-derived mesenchymal stem cells itself has become an important topic.OBJECTIVE:To explore ways to delay the aging of bone marrow-derived mesenchymal stem cells by changing the expression of telomerase Cajal body protein 1(TCAB1)gene.METHODS:Mouse bone marrow-derived mesenchymal stem cells were cultured by cell adhesion method.TCAB1 gene in bone marrow-derived mesenchymal stem cells was overexpressed and interfered by recombinant lentivirus technique.The expression of aging related genes P16,P21,P53,and P27 was detected by qPCR.The relative length of telomeres was detected by qPCR.The expression of aging proteins P16,P21,P53,and P27 was detected by western blot assay.Cell proliferation was detected by CCK-8 assay.Annexin V-PE/7-AAD apoptosis kit was used to detect the degree of cell apoptosis.RESULTS AND CONCLUSION:Bone marrow-derived mesenchymal stem cell lines overexpressing TCAB1 gene had decreased expression of senescence related genes and proteins,increased Telomere relative length,stronger cell proliferation,less apoptosis,and a youthful state.The expression of age-related genes and proteins in bone marrow mesenchymal stem cells interfering with TCAB1 gene increased,and the relative telomere length decreased;cell proliferation ability was weak;cell apoptosis was more,and cells showed senescence.These results indicate that increasing the expression of TCAB1 in an appropriate range can delay the rate of cell senescence.

Objective:To establish a practical patient-based internal quality control method for valproic acid drug concentration monitoring.Methods:Observational Study. A PBRTQC model based on the exponentially weighted moving average (EWMA) method was established using Python. All results of a total of 28, 757 valproic acid concentration data from February 1, 2023 to January 31, 2024 were collected and split into training set and validation set at a ratio of 80% and 20% respectively. The truncation limit (TL) was optimized by using the winsorized mean method and the trimmed mean method. Different weighting coefficients λ were set. Different TL and different λ were combined with the EWMA algorithm into different patient-based real-time quality control (PBRTQC) models. The optimized models were verified by introducing simulated constant errors (CE) and proportional errors (PE) respectively. The false positive alarm rate (FAR) was used to evaluate specificity, and the average number of patients before error detection (ANPed) was used to evaluate sensitivity. According to the daily test volume and quality target requirements, we comprehensively judged whether the performance evaluation indicators of FAR and ANPed meet the laboratory requirements. Bias detection curve was used for determination of the best model.Results:The parameters of the best PBRTQC model for valproic acid drug concentration monitoring are: trimmed mean method with 1.5 standard deviations (i.e., truncating data outside 1.5 standard deviations of the data mean), λ=0.01. The performance verification result shows that ANPed of CE and PE of this model are both less than 100. The comparison between the EQA results and the EWMA results show that the EWMA method results are comparable to the EQA results.Conclusion:A PBRTQC model for the valproic acid drug concentration monitoring project based on the EWMA method has been successfully established. It is comparable with both IQC and EQA results, which means PBRTQC may be used as a supplement to the quality control of daily quality control products.

Objective To analyze risk factors of acute cardio-cerebrovascular accidents in elderly patients with lower extremity fracture,and to construct a risk prediction diagram model.Methods A retrospective analysis was conducted on the clinical data of 510 elderly patients with lower extremity fractures,and the patients were divided into the occurrence group and the non-occurrence group based on the occurrence of acute cardiovascular and cerebrovascular accidents during the postoperative hospitalization.Univariate and multivariate Logistic regression analysis was used to analyze risk factors affecting acute cardiovascular and cerebrovascular accidents in elderly patients with lower extremity fracture,and the risk prediction model was constructed and verified.Results A total of 52 cases of acute cardio-cerebrovascular accidents occurred during hospitalization in 510 patients(10.20%).Age,ASA grade Ⅲ ratio,preoperative concurrent cerebrovascular disease,postoperative pneumonia ratio and postoperative bed time≥5 days ratio were higher in the occurrence group than those in the non-occurrence group(P＜0.05).Multivariate Logistic regression analysis showed that age,ASA grade Ⅲ,preoperative concurrent cardiovascular and cerebrovascular disease,and postoperative pneumonia were risk factors for acute cardio-cerebrovascular accidents in elderly patients with lower limb fracture(P＜0.05).Multivariate Logistic regression analysis was used to screen risk factors as predictive variables to build a risk early warning histogram model for acute cardio-cerebrovascular accidents.The total score ranged from 103 to 168 points,corresponding to a risk range of 0.1 to 0.9 points.Receiver operating characteristic curve(ROC)curve results showed that the area under the curve(AUC)of this model for predicting acute cardiovascular and cerebrovascular accidents was 0.980(95%CI:0.964-1.000),and discrete choice approach(DCA)showed that when the risk threshold was 0.2-0.6,the prediction model of this column graph had a good clinical advantage.Conclusion The risk diagram model constructed based on risk factors has good predictive value for the occurrence of acute cardio-cerebrovascular accidents after lower extremity fracture in elderly patients.

BACKGROUND:Adipose-derived stem cells have anti-aging effects,but whether adipose-derived stem cells from donors of different ages are different needs further study. OBJECTIVE:To compare the biological properties of adipose-derived stem cells in old and young mice. METHODS:Adipose-derived stem cells were extracted from adipose tissue of C57BL mice aged 8 and 14 weeks,respectively.The differences of cell cycle,apoptosis,and proliferation of adipose-derived stem cells in old and young mice were compared.The expression levels of aging-related P21 and P27 genes and proteins of adipose-derived stem cells in old and young mice were detected by quantitative PCR and western blot assay. RESULTS AND CONCLUSION:Compared with old mouse adipose-derived stem cells,young mouse adipose-derived stem cells were more active,more regular in morphology,less apoptosis,faster proliferation,and lower in expression of age-related P21 and P27 genes and proteins.It has been proven that adipose-derived stem cells from young mice have better anti-aging effects.
