The endoplasmic reticulum (ER) and mitochondria are critical organelles in maintaining cellular homeostasis and regulating cell fate. However, current biological and chemical approaches for modulating ER and mitochondrial functions often lack specificity and spatiotemporal controllability, potentially leading to off-target or systemic effects that limit their clinical applications. Here, by synthesizing a physical stimulus-based acoustoelectric nanoregulator, barium zirconate titanate (BZT) nanoparticles (NPs) with enhanced piezoelectric properties, we aimed to modulate ER and mitochondrial functions by regulating intracellular concentrations of calcium ions (Ca2+) and hydrogen ions (H+), thereby enabling spatiotemporally controllable modulation of cell fate. BZT NPs significantly modulated calcium ion dynamics and pH in tumor cells under ultrasound stimulation, accompanied by perturbations in ER and mitochondrial homeostasis, induction of ER stress and mitophagy, and ultimately alterations in cell fate. In the tumor-bearing mouse model, the acoustoelectric nanoregulator spatiotemporally modulates the intracellular environment through electrical signaling and ionic dynamic modulation under ultrasound stimulation, expanding the application prospects of physical stimulation-based strategies for abnormal cell function regulation. Our findings provide fresh perspectives for understanding cellular stress responses and cell fate determination processes, and lay the foundation for developing novel interventions in precision therapy and cell engineering applications.
The liver is the primary target organ for hematogenous metastasis of colorectal cancer, and colorectal cancer liver metastasis is one of the key and challenging aspects in its treatment. In order to improve the diagnosis and comprehensive treatment of colorectal cancer liver metastasis, the guideline development group has summarized advanced experiences and the latest achievements from both domestic and international sources, and has once again revised and updated the Guideline for the diagnosis and comprehensive treatment of colorectal cancer liver metastases (2025 edition) to continuously provide guidance and reference for clinical practice in this field.
The emergence of targeted therapies against the epidermal growth factor receptor (EGFR) has transformed the treatment landscape for metastatic colorectal cancer (mCRC). However, the absence of methodologies capable of dynamically monitoring drug-target engagement and subsequent molecular responses at high sensitivity represents a critical translational gap, impeding personalized treatment adaptation. Here, we report an integrated nanoscale sensing platform that synergizes a high-quality-factor (high-Q) Terahertz (THz) metasensor with modularly engineered exosome-targeting theranostic probe (Exo-TTprobe) for ultrasensitive, longitudinal evaluation of targeted therapy efficacy. By exploiting exosomes as natural nanocarriers of membrane-bound drug-target complexes, our system achieves specific detection through a dual amplification strategy combining rolling circle amplification (RCA) and gold nanoparticle-enhanced THz transmission shifts. The platform exhibits exceptional sensitivity with a detection limit of 103 particles/ml across a dynamic range spanning 103 to 108 particles/ml, enabling discrimination of heterogeneous EGFR expression and drug response in cetuximab-sensitive and non-sensitive CRC cell lines within hours of cetuximab exposure. Most notably, in a clinical cohort of 15 mCRC patients, we successfully captured therapy-specific molecular signatures directly from plasma-derived exosomes, identifying statistically significant differential signals within 12 h of targeted therapy, which further intensified by 24 h. Compared to traditional imaging evaluation, our method has the potential for early assessment of targeted therapy and adaptation to precision medicine. This work establishes a transformative paradigm for real-time, molecular-level monitoring of targeted therapeutics, with broad potential applicability across diverse oncogenic drivers and cancer types.
Patients with unresectable large HCC may be downstaged through TACE followed by MWA to achieve curative treatment. Controversially, for some patients, single MWA treatment may be sufficient. This study aimed to evaluate the clinical outcomes of unresectable large HCC treated with transarterial chemoembolization (TACE) followed by microwave ablation (MWA) and compare them based on the tumor burden score (TBS), to provide a scientific basis for guiding treatment strategies. This retrospective study included 294 patients with unresectable large HCC (449 tumors) treated with MWA between January 2010 and June 2023 at the General Hospital of the People’s Liberation Army. Propensity score matching (PSM) was used to compare the TACE sequential MWA group (n = 103) with the single MWA group (n = 103). The primary endpoint was progression-free survival (PFS), with secondary endpoints including overall survival (OS) and occurrence of adverse events. Subgroup analyses were conducted by identifying TBS split points using the interaction cubic spline plot method. Among the 294 patients, 76.5
Abstract Background This study compared the learning curves and clinical outcomes of osteotomy guide robot and guide plate-based robot-assisted total knee arthroplasty (TKA). Patients and methods From January to May 2023, 100 patients were prospectively enrolled to receive either a guide plate-based robot or an osteotomy guide robot-assisted total knee arthroplasty. The thickness of the osteotomy planned by the robot and the actual thickness were recorded in real time during the operation, as was the time taken for each step in the operation, including bone registration and osteotomy. The SF-12, HSS score, and FJS of the patients before surgery and 6 weeks and 24 months after surgery were also collected. Results For surgeon 1, the average operating time with the guide plate-based robot and osteotomy guide robot was 98.16 ± 9.68 and 118.52 ± 15.95 min, respectively; the difference was significant. The average time of the last 10 cases was shorter than that of the first 10 cases. The inflection points of the osteotomy learning curve of surgeon 1 with two robotic systems were at case 5 and case 9. The average operative times for Surgeon 2’s two robotic surgery groups were 104.52 ± 12.65 min and 105.76 ± 33.03 min, respectively. The inflection points of the osteotomy learning curves using the two robotic systems occurred at case 13, respectively. Patients who underwent guide plate-based robot or osteotomy guide robot-assisted TKA had similarly improved knee recovery, reflected in the SF-12, HSS score, and FJS. Conclusions There was no significant difference in the osteotomy learning curve between the two robotic systems. The improvement in knee functional recovery was similar after the guide plate-based robot and the osteotomy guide robot-assisted TKA. Level of evidence Level II.
