To address the constrains imposed by insufficient hydrogen peroxide (H2O2) and high glutathione (GSH) expression in tumor cells on the efficacy of chemodynamic therapy (CDT), zeolitic imidazolate framework-8 (ZIF-8) loaded with disulfiram (DSF) and 3-amino-1,2,4-triazole (3-AT) was synthesized via a one-pot approach. Subsequently, hyaluronic acid (HA)-modified cupric peroxide (CuO2) was in-situ grown on its surface through biomineralization to construct a multifunctional copper-based nanozyme ADZCH (3-AT/DSF@ZIF-8@CuO2-HA). This nanoplatform disrupts the intratumoral H2O2 homeostasis, depletes GSH, and synchronously delivers DSF and Cu2+ via cascade catalysis, thereby enhancing CDT and sensitizing tumors to DSF-based chemotherapy. The results of physicochemical characterization indicated that ADZCH presented a uniform core-shell structure with favorable dispersibility. Its particle size and Zeta potential were 196.5 nm and −19.5 mV, respectively. It possessed a microporous structure with a specific surface area of 81.8600 m2/g, and demonstrated efficient loading capacity for DSF and 3-AT, achieving drug loading efficiencies of 5.91% and 45.07%, respectively. Moreover, ADZCH can continuously and slowly release drugs in an acidic environment and maintain good stability under diverse physiological conditions. In vitro functional assays verified that ADZCH catalytically generated H2O2 and hydroxyl radicals while concurrently depleting GSH in a concentration- and incubation time-dependent manner. Cellular uptake experiments showed that HA modification significantly improved the uptake of nanoparticles by 4T1 cells. Cytotoxicity tests showed that 80 μg/mL ADZCH had a significant cytotoxic effect on 4T1 cells but no significant toxicity on L929 cells. DCFH-DA probe detection indicated that ADZCH could significantly induce intracellular reactive oxygen species (ROS) generation, thereby enhancing CDT efficacy. Live/dead staining experiments showed that ADZCH efficiently induced apoptosis, with the proportion of dead cells reaching 94.74%, demonstrating its promising potential for anti-tumor applications.This study provides new research ideas and experimental basis for overcoming the tumor microenvironment barrier and enhancing the anti-tumor effect of CDT combined with chemotherapy.

Cardiac aging is a key factor in the onset and progression of cardiovascular diseases. Investigating the traditional Chinese medicine （TCM） pathogenesis and therapeutic principles of cardiac aging is of great importance for curbing the common phenomenon of the heart aging faster than the body and implementing the national strategy in response to population aging. Essence （Jing）， Qi， and spirit （Shen） are the origin， driving force， and manifestation of life， respectively. The Essence-Qi-spirit theory within the Qi-collateral doctrine delineates the core pathogenesis and therapeutic principles of aging. This framework identifies kidney essence deficiency as the fundamental cause of aging， with primordial Qi depletion as a key factor and the consumption of body and spirit as its manifestations. Corresponding treatment principles involve tonifying the kidney to replenish essence， warming and supporting primordial Qi， and nourishing the body and spirit. During the process of tonifying the kidney， regulating Yin and Yang remains essential. Relevant studies indicate that this theoretical system provides significant guidance for anti-aging research in TCM. Guided by the Essence-Qi-spirit theory within the Qi-collateral doctrine， this paper posits that kidney essence constitutes the material foundation for cardiac development， and primordial Qi acts as the fundamental driver of cardiac function. Physical form and spirit together provide the structural carrier and functional manifestation of the heart. We further propose the core pathogenesis and therapeutic principles for cardiac aging. The fundamental pathogenesis lies in the deficiency and decline of kidney essence， leading to malnourishment of the heart. The key pathogenesis is the deficiency of primordial Qi， resulting in obstruction of the heart collateral. The manifestation involves the accumulation in the collateral and the dysfunction of the heart spirit. The corresponding treatment principles are tonifying the kidney and replenishing essence to nourish the heart， warming and reinforcing primordial Qi to unblock the heart collateral， and fortifying the physical form to invigorate the spirit mechanism. Existing studies demonstrate that Bazi Bushen Capsules， with the effects of tonifying the kidney， replenishing essence， warming primordial Qi， and fortifying the physical form and spirit， can delay cardiac aging. Guided by the Essence-Qi-spirit theory within the Qi-collateral doctrine， these findings support the development of effective herbal formulas to intervene in cardiac aging.

Objective:To establish tumor specific protein (SP70) targeted tumor cell enrichment technology and to assess applicational value of next-generation sequencing (NGS) analysis for enriched circulating tumor cell (CTC) in precision medicines of non-small cell lung cancer (NSCLC).Methods:The monoclonal antibody NJ001 was covalently coupled to the surface of magnetic beads to build targeted magnetic bead enrichment technology based on SP70. The limit of detection, coincidence rate, interference experiment, recovery test and clinical performance were evaluated. From March 2016 to August 2017, NGS analysis with or without pre-treatment of targeted enrichment for serous fluids of 43 NSCLC in the First Affiliated Hospital with Nanjing Medical University were compared (Kappa or Fisher exact test).Results:The CTC enrichment technology based on SP70 targeted immunomagnetic beads can specifically enrich tumor cells. The limit of detection was 10 4 SPC-A1 cells/L, and the coincidence rate, sensitivity and specificity were 100% (3/3). The endogenous interfering substances such as red blood cells, hemoglobin, white blood cells, epithelial cells and triglycerides had no interfering effects, as well as the exogenous interfering substances such as EDTA-K2, cefoxitin, carboplatin and paclitaxel. The recovery rate was 56.0% (56 000/100 000). A total of 30 gene mutations including 65 loci were found in 43 NSCLC under SP70 targeted enrichment, with a higher detection rate compared with unenrichment method [95.0% (19/20) vs 65.0% (13/20), χ 2=5.625, P=0.044]. Conclusion:In this study, SP70-targeted enriched CTC liquid biopsy method was established, with higher sensitivity and specificity of NGS detection than unenrichment method.

Objective To explore the characteristics of military training injuries in high-altitude troops and determine the possible impact of daily diet on these training injuries in order to provide theoretical reference for scientific training and medical service support for high-altitude troops.Methods A cross-sectional scheme was adopted in this study.A self-designed Military Training Injury Questionnaire for Plateau Troops was used to survey the officers and soldiers from resident high-altitude troops in July 2024 for their training injuries,daily diet,and other situations.The obtained data were statistically analyzed.Results Among the 3 655 participants,the incidence of military training injuries was 17.87%.The subject with highest incidence was physical training(45.94%),the most common season was winter(31.39%).The most common sites of injury were waist(28.48%),knees(22.21%),and ankles(18.07%),and the most common types were sprains(28.48%),chronic fatigue injuries(18.38%)and strains(12.25%).The intake amounts of coarse grains and potatoes,bean products,aquatic products and nuts were relatively low in the daily diet of high-altitude troops.Multivariate logistic regression analysis found intake of fruit(OR=0.625,95%CI:0.508～0.768,P<0.001)and of nut(OR=0.759,95%CI:0.654～0.879,P<0.001)were correlated with the occurrence of training injury.Conclusion The occurrence pattern of military training injuries in high-altitude troops in this survey is basically consistent with that of previous reports,but the incidence rate is slightly decreased.Regular consumption of fruit and nut may be protective factors for the occurrence of training injuries.

Acute kidney injury (AKI) is a critical clinical condition characterized by rapid renal function decline, with high morbidity, mortality, and healthcare costs. Traditional Chinese medicine (TCM) has shown potential effects on mitigating oxidative stress and programmed cell death in AKI models. Scutellaria barbata D. Don (SB) and Scleromitrion diffusum (Willd.) R. J. Wang (SD), a classic TCM herbal pair exhibited anti-inflammatory and antioxidant activities. Using advanced chromatographic separation technology, we enriched the effective fractions of water extracts from SB-SD, obtaining self-assembled herbal nanoparticles (SB and SD nanoparticles, SSNPs) rich in flavonoids and terpenoids. These SSNPs demonstrated robust antioxidant properties in vitro and mitigated AKI progression in vivo by activating the nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway. Oral administration of SSNPs in mice resulted in absorption into the bloodstream, formation of a protein corona, reduced macrophage phagocytosis, and enhanced bioavailability and renal targeting. Furthermore, we investigated the self-assembly principle of SSNPs using representative flavonoids and terpenoids. Kinetic studies and in situ transmission electron microscopy (in situ TEM) revealed that these compounds self-assemble via supramolecular forces like hydrogen bonding and π-π interactions, forming stable nanostructures. This study elucidates the renoprotective effects and mechanisms of SB and SD, and provides a novel approach for the development of TCM-based nanomedicines, highlighting the potential of nano-TCM in AKI treatment.
