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 observe the clinical efficacy and safety of Yishen Jiangtang decoction combined with conventional Western medicine treatment in managing stage G3A3 diabetic kidney disease （DKD） in the patients with the pattern of Qi-Yin deficiency combined with dampness-heat and blood stasis， and to explore its mechanism of inhibiting the endoplasmic reticulum stress （ERS）-apoptosis axis and delaying renal fibrosis （RF）. 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.

Objective: To investigate the health literacy level and its influencing factors among the elderly in Shunyi District, Beijing Municipality, so as to provide the evidence for developing health literacy intervention measures and improving the elderly's health literacy level. Methods: From September to November 2024, permanent residents aged ≥60 years in Shunyi District were selected by a multi-stage random sampling method combined with probability proportionate to size sampling method. The Chinese Elderly Health Literacy Questionnaire was used to conduct face-to-face surveys on basic information, health status, and health literacy. The health literacy level of the elderly was analyzed. Multivariable logistic regression model and decision tree model were used to analyze the influencing factors for health literacy level of the elderly. Results: There were 285 males (47.50%) and 315 females (52.50%). The mean age was (68.91±7.38) years. The health literacy level of the elderly was 14.33%. The literacy levels of basic concepts, basic knowledge, and basic skills were 43.33%, 5.33%, and 50.83%, respectively. The literacy levels of scientific aging concept, intrinsic capacity and geriatric syndromes, healthy lifestyle, information acquisition and self-care, health service utilization and chronic disease management, and safety and first aid were 52.33%, 7.17%, 51.83%, 58.83%, 72.00%, and 4.33%, respectively. Multivariable logistic regression analysis showed that educational level (high school/technical secondary school/technical school and above, OR=2.376, 95%CI: 1.020-5.532), monthly household income per capita (1 000-<3 500 yuan, OR=2.973, 95%CI: 1.349-6.555), residence (urban, OR=3.836, 95%CI: 2.071-7.105), and health attention (relatively concerned, OR=4.164, 95%CI: 1.779-9.742) were influencing factors for health literacy level of the elderly. Decision tree model results showed that educational level, monthly household income per capita, residence, and health attention were influencing factors for health literacy level of the elderly, with residence being the main influencing factor. Elderly people living in urban areas, relatively concerned about health, and with high school/technical secondary school/technical school and above educational level had higher health literacy level (40.00%). Conclusions The health literacy level of the elderly in Shunyi District is mainly affected by educational level, monthly household income per capita, residence, and health attention. It is recommended to focus on rural elderly with lower educational level, monthly household income per capita, and health attention.

A 67-year-old male had undergone bilateral lung transplantation for chronic obstructive pulmonary disease 11 months before the current presentation. He was admitted with a 5-day history of cough with sputum, and a 2-day history of fever. Computed tomography (CT) of the chest revealed rapidly progressive bilateral diffuse "ground glass" opacities. Despite anti-infective therapy and methylprednisolone pulse therapy, his condition deteriorated, necessitating endotracheal intubation with mechanical ventilation and veno-venous extracorporeal membrane oxygenation (V-V ECMO) for life support. A bedside cryobiopsy was undertaken, with pathology confirming the organizing pneumonia diagnosis. Comprehensive treatment was continued: methylprednisolone, tacrolimus for immunosuppression, and prophylactic anti-infectives. His partial pressure of oxygen in the blood by the fraction of inspired oxygen ratio and imaging findings improved gradually. ECMO support was discontinued after 2 weeks, and he was discharged 1-month later, resuming normal daily activities. At 2-month follow-up, he exhibited improved exercise tolerance. Chest CT showed bilateral upper-lobe emphysema (predominantly upper-lobe reticular shadows) and significant bilateral upper-lobe pleural thickening. After 12 months of fllow-up, a diagnosis of chronic lung allograft dysfunction was made based on imaging findings and the trajectory of pulmonary function.

BACKGROUND:Adipose tissue-derived mesenchymal stem cells release a large amount of exosomes to participate in various pathophysiological processes,but the impact and precise mechanism of exosomes derived from adipose tissue-derived mesenchymal stem cells on autophagy of hepatic stellate cells have not been fully elucidated.OBJECTIVE:To explore the targeted regulatory effect and molecular mechanism of adipose tissue-derived mesenchymal stem cell-derived exosomes on autophagy of hepatic stellate cells through miR-15a-5p.METHODS:Adipose tissue was collected from inguinal region of 8-week male C57BL/6 mice.Adipose tissue-derived mesenchymal stem cells were extracted by collagenase digestion.Adipose tissue-derived mesenchymal stem cell-derived exosomes were extracted by ultracentrifugation.Mouse liver tissue was obtained,and hepatic stellate cells were isolated and extracted using collagenase perfusion digestion and density gradient centrifugation.The experiment was divided into two groups.In control group,hepatic stellate cells were cultured alone for 48 hours.In the exosome group,hepatic stellate cells were co-cultured with adipose tissue-derived mesenchymal stem cell-derived exosomes for 48 hours.The effects of exosomes on hepatic stellate cell proliferation,activation,autophagy,and expression of fibrosis markers were detected by western blot assay,RT-qPCR,and immunofluorescence staining.RT-qPCR and western blot assay were used to detect the effect of exosomes on the mRNA and protein expression of miR-15a-5p and the downstream signaling pathway Bcl-2,Beclin-1,and Rubicon in hepatic stellate cells.RESULTS AND CONCLUSION:(1)Compared with the control group,the ratio of autophagy markers LC3-Ⅱ expression decreased,the number of autophagosome was also significantly decreased,and the intracellular lipid droplets were regenerated,simultaneously,cell volume diminished with the weakening of proliferation in hepatic stellate cells of the exosome group,indicated that the hepatic stellate cell activation was significantly inhibited.(2)Compared with the control group,the expressions of α-smooth actin and type Ⅰ collagen were significantly decreased(P＜0.01),and the expression of miR-15a-5p was significantly increased in hepatic stellate cells of the exosome group(P＜0.01).At the same time,the expression of its downstream target gene Bcl-2 was significantly decreased(P＜0.01),while the expressions of autophagy genes Beclin-1 and Rubicon were significantly increased in hepatic stellate cells of the exosome group(P＜0.01).The results indicate that adipose tissue-derived mesenchymal stem cell-derived exosomes inhibits the expression of Bcl-2 in hepatic stellate cells by targeting miR-15a-5p and increases the expression of downstream autophagy genes Beclin-1 and Rubicon,thereby inhibiting the autophagy of hepatic stellate cells.

Urothelial carcinoma (UC), including bladder urothelial carcinoma and upper tract urothelial carcinoma (UTUC), is the most common malignant tumor in the urinary system. Traditional cell line models fall short in simulating its tumor microenvironment and in vivo behavior. Patient-derived organoid (PDO) models offer a new way to overcome these shortcomings. This paper reviews the construction techniques of PDO models in UC, their biological simulation capabilities, and their applications in preclinical research. It also analyzes the technical limitations of these models. PDO models can retain the histological, genomic, and transcriptomic features of the parent tumor and accurately simulate the tumor microenvironment and biological behavior. They have been widely used in bladder cancer research, providing a precise platform for drug screening, personalized treatment, and immunotherapy evaluation. However, their use in UTUC research is still in its infancy. In the future, through technological optimization, PDO models are expected to enhance their value in UC research, advancing precision medicine research and clinical translation.

Objective:To investigate the clinical outcomes of nephron-sparing surgery (NSS) for tuberous sclerosis complex(TSC) -associated renal angiomyolipoma (RAML). Methods:This retrospective case-series study analyzed the clinical data of 15 TSC-RAML patients who underwent NSS at the Department of Urology, Peking Union Medical College Hospital between April 2013 and July 2024. The cohort included 4 males and 11 females. The age at TSC diagnosis was (28.5±14.5) years (range: 5 to 62 years), and the age at first surgery was (33.3±10.8) years (range: 18 to 62 years). The maximum tumor diameter( M(IQR)) was 6.4(7.9)cm (range: 3.5 to 31.5 cm). Patient baseline characteristics, surgical approach, TSC-RAML staging, imaging findings, and laboratory data were collected. Relationships between variables were analyzed using Generalized Estimating Equations with post-hoc tests. Results:A total of 18 surgical procedures were performed on the 15 patients. These included 7 open surgeries, 9 laparoscopic surgeries, and 2 laparoscopic procedures converted to open surgery. The mean preoperative serum creatinine level was (70.2±14.2) μmol/L (range: 50 to 101 μmol/L), which increased to (99.2±29.8) μmol/L (range: 47 to 171 μmol/L) on postoperative day 1. However, at one year postoperatively, serum creatinine was (76.8±13.5)μmol/L (range: 55 to 106 μmol/L),showed no significant difference from preoperative levels ( P>0.05). At the 6-month postoperative follow-up, the Utrecht Interventional Classification stage for all treated tumors had decreased to grade 1 or 2. At the 12-month follow-up (available for 13 patients), 11 patients showed no disease progression. Conclusions:NSS is a viable treatment option for rigorously selected patients with high-stage TSC-RAML. Although NSS causes transient renal function impairment, it provides effective tumor burden control. In stringently selected patients with high-stage disease and under long-term follow-up, NSS is associated with limited long-term renal impairment.

Objective:To evaluate the efficacy and feasibility of a domestically developed robotic surgical system based on fiber-optic dedicated line communication in cross-regional urological telesurgery.Methods:This was multicenter，single-arm，retrospective case series study. The data of patients who underwent urological telesurgeries using the telesurgical system between January 2023 and December 2024 were analyzed. The cohort included 59 patients from seven hospitals across China. Among the patients，47 were male（79.7%）and 12 were female（20.3%），with a median age of 63.0（56.0，68.0）years and a body mass index of（24.7 ± 3.0）kg/m 2. Surgical procedures included 32 radical prostatectomies，24 partial nephrectomies，one radical nephrectomy，one adrenalectomy，and one ureteral reconstruction. The perioperative indicators，pathological results and postoperative complications were analyzed. The network monitoring data were collected，and the perioperative data of patients，remote system monitoring data and costs were compared between the two communication modes of optical transport network（OTN）and cloud-connect network（CCN）. Results:All 59 remote surgeries were successfully completed，with a mean operative time of（138.0 ± 54.0）minutes，median intraoperative blood loss of 50.0（30.0，100.0）ml and a postoperative hospital stay of 5.0（4.0，6.0）days. No cases required reoperation，Clavien-Dindo grade ≥3 complications，or readmission. The geographical distance between the primary and remote surgical sites ranged from 450 to 2 800 km. Network monitoring revealed increased bidirectional latency with distance increasing：the shortest latency time（Hefei-Hangzhou，450 km）was（16.59 ± 0.80）ms，while the longest（Harbin-Hangzhou，2 200 km）latency time was（53.31 ± 0.31）ms. Average frame loss per procedure was 0?1.27 frames. The results of subgroup analysis comparing OTN and CCN communication modes showed no significant differences in operative time［（130.7 ± 70.5）minutes vs.（142.1 ± 42.9）minutes， P = 0.442］，postoperative hospitalization［6.0（4.0，8.0）d vs. 5.0（4.0，6.0）d， P = 0.581］，or readmission rates（0 vs. 0）. However，CCN demonstrated significant cost advantages with 500 RMB per operation vs. 3 000 RMB per operation for OTN. Conclusions:Urological telesurgery using fiber-optic communication is feasible. The CCN mode，with its cost-effectiveness，excellent usability，and multi-point interconnection flexibility，is currently the preferred communication model for telesurgical applications.
