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.

Objective To investigate the exposure-response relationships and lag effects between air pollutants (PM2.5, PM10, O3, and NO2) and mortality in Jiading District, Shanghai, and to provide a scientific basis for the formulation of environmental health policies. Methods Using an individual-level time-stratified case-crossover design, conditional logistic regression models in conjunction with a distributed lag nonlinear model (DLNM) were employed to analyze the exposure-response relationship and temporal lag patterns of ambient air pollution on resident mortality in Jiading District (1994–2024). Results A total of 59 048 death cases were collected, including 18,701 deaths from cardiovascular diseases and 11 731 deaths from respiratory diseases. PM2.5 and NO2 had a significant impact on all-cause mortality, cardiovascular disease mortality, and respiratory disease mortality, with the most significant effects observed within a lag of 0–3 days. PM10 also had some impact on these three types of mortality, but its effect was generally weaker than that of PM2.5 and NO2. The exposure-response curves showed that the risk of death increased rapidly with increasing concentrations of PM2.5 and PM10, while the effect of NO2 plateaued at higher levels. No significant differences were found across age or gender subgroups. Conclusion Short-term exposure to PM2.5, PM10, and NO2 significantly increases all-cause mortality risk in Jiading District, with effects persisting up to 7 days, highlighting the need for enhanced air pollution control measures, particularly targeting fine particulate matter.

Objective:To investigate the impact of different ventilation modalities during initial resuscitation on short-term outcomes in adult patients with in-hospital cardiac arrest (IHCA).Methods:This retrospective study included adult patients (age ≥18 years) admitted to the emergency resuscitation or observation units of our hospital from September 2019 to December 2021. Demographic data, comorbidities, and short-term outcomes of IHCA patients who underwent airway management during resuscitation were recorded. Participants were stratified into non-advanced airway and advanced airway groups based on ventilation modality. The primary outcome was defined as sustained return of spontaneous circulation (ROSC) ≥20 min, and secondary outcomes included survival to discharge and favorable neurological status at discharge. Logistic regression analyses were performed to assess the impact of different ventilation modalities on short-term outcomes among adult IHCA patients. and developed a prediction model of ROSC for adult IHCA patients, and its predictive performance was evaluated by the area under the curve (AUC) of the receiver operating characteristic.Results:Among 285 IHCA patients (non-advanced airway: n=75; advanced airway: n=210), 127 achieved ROSC ≥20 min, 51 survived to discharge, and 35 had favorable neurological outcomes. Logistic regression identified ventilation modality, epinephrine dose, and arrest location as independent predictors of ROSC in adult IHCA patients. Advanced airway management demonstrated significantly higher ROSC rates compared to non-advanced interventions ( OR=3.698, 95% CI:1.844-7.419, P<0.001). However, no significant associations were observed between ventilation modalities and survival to discharge ( OR=1.097, 95% CI:0.506-2.376, P=0.815) or favorable neurological outcomes at discharge ( OR=0.548, 95% CI:0.224-1.339, P=0.187). Ventilation modality, epinephrine dose, and arrest location were incorporated as predictors in a multivariable logistic regression model to develop a ROSC prediction model for adult IHCA patients. The discriminative ability of model was evaluated through receiver operating characteristic (ROC) curve analysis, yielding an AUC of 0.735 (95% CI:0.678-0.793). Subgroup analyses demonstrated that early advanced airway management significantly enhanced ROSC rates in noncardiac etiology cases, whereas no such benefit was observed in cardiac etiology cases, while this intervention correlated with decreased survival to discharge rates and deteriorated neurological outcomes among survivors. Conclusions:Advanced airway management demonstrated improved ROSC rates in adult IHCA cases, while showing no significant improvement in survival rates or favorable neurological outcomes at discharge. Ventilation modality, epinephrine dose, and arrest location are independent predictors of ROSC. A model integrating these factors exhibits moderate predictive utility for IHCA outcomes.

This study explored the effect of the Mycobacterium tuberculosis(Mtb)PE/PPE family protein PE_PGRS37 on the growth of Mycobacterium smegmatis(Ms)and macrophage autophagy during Mtb infection.The pe_pgrs37 gene was amplified from Mtb genome through PCR,and the recombinant vector pAIN-PE_PGRS37 was successfully constructed through homologous recombi-nation.pAIN-PE_PGRS37 and pAIN were integrated into Ms through electroshock to construct pAIN-PGRS37/Ms and pAIN/Ms re-combinant bacteria.Western blotting indicated that the PE_PGRS37 protein was correctly expressed in pAIN-PE_PGRS37/Ms.The re-combinant bacteria were inoculated in 7H9/7H10 medium,and their colony morphology and growth curves were observed.No signifi-cant difference in colony morphology was observed between pAIN-PE_PGRS37/Ms and pAIN/Ms.The growth rate significantly in-creased between 10 and 16 h,and a plateau was reached at 26 h.After infection of U937 cells with pAIN-PE_PGRS37/Ms and pAIN/Ms,macrophage autophagy flow was detected with western blotting and immunofluorescence.In the pAIN-PE_PGRS37/Ms-infected group,compared with the pAIN/Ms-infected group,macrophage LC3-II and p62 protein expression was significantly up-regulated(P<0.001)and inhibited autophagosome and lysosome fusion.The intracellular survival of the recombinant bacteria was detected through colony counting,and pAIN-PE_PGRS37/Ms showed significantly greater survival in macrophages at 12 h,24 h,and 48 h than pAIN/Ms(P<0.05).Our results suggested that PE_PGRS37 protein promotes Mycobacterium survival in macrophages by blocking macro-phage autophagy flow,thus inhibiting macrophage autophagy.

Background::While type 2 diabetes mellitus (T2DM) is considered a putative causal risk factor for coronary artery disease (CAD), the intrinsic link underlying T2DM and CAD is not fully understood. We aimed to highlight the importance of integrated care targeting both diseases by investigating the phenotypic and genetic relationships between T2DM and CAD.Methods::We evaluated phenotypic associations using data from the United Kingdom Biobank ( N = 472,050). We investigated genetic relationships by leveraging genomic data conducted in European ancestry for T2DM, with and without adjustment for body mass index (BMI) (T2DM: Ncase/ Ncontrol = 74,124/824,006; T2DM adjusted for BMI [T2DM adjBMI]: Ncase/ Ncontrol = 50,409/523,897) and for CAD ( Ncase/ Ncontrol = 181,522/984,168). We performed additional analyses using genomic data conducted in multiancestry individuals for T2DM ( Ncase/ Ncontrol = 180,834/1,159,055). Results::Observational analysis suggested a bidirectional relationship between T2DM and CAD (T2DM→CAD: hazard ratio [HR] = 2.12, 95% confidence interval [CI]: 2.01–2.24; CAD→T2DM: HR = 1.72, 95% CI: 1.63–1.81). A positive overall genetic correlation between T2DM and CAD was observed ( rg = 0.39, P = 1.43 × 10 -75), which was largely independent of BMI (T2DM adjBMI–CAD: rg = 0.31, P = 1.20 × 10 –36). This was corroborated by six local signals, among which 9p21.3 showed the strongest genetic correlation. Cross-trait meta-analysis replicated 101 previously reported loci and discovered six novel pleiotropic loci. Mendelian randomization analysis supported a bidirectional causal relationship (T2DM→CAD: odds ratio [OR] = 1.13, 95% CI: 1.11-1.16; CAD→T2DM: OR = 1.12, 95% CI: 1.07-1.18), which was confirmed in multiancestry individuals (T2DM→CAD: OR = 1.13, 95% CI: 1.10-1.16; CAD→T2DM: OR = 1.08, 95% CI: 1.04-1.13). This bidirectional relationship was significantly mediated by systolic blood pressure and intake of 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors, with mediation proportions of 54.1% (95% CI: 24.9-83.4%) and 90.4% (95% CI: 29.3-151.5%), respectively. Conclusion::Our observational and genetic analyses demonstrated an intrinsic bidirectional relationship between T2DM and CAD and clarified the biological mechanisms underlying this relationship.
