In the study by Wu , patients with unresectable hepatocellular carcinoma were subjected to transarterial chemoembolization (TACE) as a conversion therapy in order to render their tumors suitable for resection. A nomogram was devised and shown to be effective in predicting the survival of these patients. Generalization of the results, however, is questionable since the study subjects consisted of patients who had resection after TACE while excluding patients with the same disease but not suitable for TACE. Immunotherapy can be considered to be an option for conversion therapy. However, markers for determining responses to a conversion therapy and for guiding the decision between TACE and sequential immunotherapy have been lacking. The question of whether effective conversion therapy can truly enhance overall survival remains unanswered.

Chemodynamic therapy (CDT) has garnered significant attention in the field of tumor therapy due to its ability to convert overexpressed hydrogen peroxide (HO) in tumors into highly toxic hydroxyl radicals (•OH) through metal ion-mediated catalysis. However, the effectiveness of CDT is hindered by low catalyst efficiency, insufficient intra-tumor HO level, and excessive glutathione (GSH). In this study, a pH/GSH dual responsive bimetallic nanocatalytic system (CuFeMOF@GOx@Mem) is developed by modifying red blood cell membranes onto glucose oxidase (GOx)-loaded Fe-Cu bimetallic MOFs, enhancing the efficacy of CDT through a triple-enhanced way by HO self-supply, catalysts self-cycling, and GSH self-elimination.

X-ray induced photodynamic therapy (X-PDT) leverages penetrating X-ray to generate singlet oxygen (O) for treating deep-seated tumors. However, conventional X-PDT typically relies on heavy metal inorganic scintillators and organic photosensitizers to produce O, which presents challenges related to toxicity and energy conversion efficiency. In this study, highly biocompatible organic phosphorescent nanoscintillators based on hydrogen-bonded organic frameworks (HOF) are designed and engineered, termed BPT-HOF@PEG, to enhance X-PDT in hepatocellular carcinoma (HCC) treatment.

Skin and soft tissue infections (SSTI) include bacterial infections of the skin, muscles, and connective tissue such as ligaments and tendons. SSTI in patients with immunocompromising diseases may lead to chronic, hard-to-heal infected wounds, resulting in disability, amputation, or even death. To treat SSTI and rebuild the defensive barrier of the skin, here we utilize recombinant type XVII collagen protein (rCol XVII) to construct biodegradable, regenerative collagen microneedles (rCol-MN) for transdermal delivery of antibacterial agents.

The integration of multiple functionalities into single theranostic platforms offers new opportunities for personalized and minimally invasive clinical interventions, positioning these materials as highly promising tools in modern medicine. Thereby, magneto-luminescent Janus-like nanoparticles (JNPs) were developed herein, and encapsulated into near-infrared (NIR) light- and pH- responsive micelle-like aggregates (Mic) for simultaneous magnetic targeting, biomedical imaging, photothermal therapy, and pH- NIR-light activated drug delivery. The JNPs consisted of NaYF:Yb,Tm upconverting nanoparticles (UCNPs) on which a well-differentiated magnetite structure (MNPs) grew epitaxially.
