Abstract
Ulcerative colitis (UC) is a chronic inflammatory bowel disease (IBD) of unknown etiology affecting the colon and rectum. Previous studies have found that reactive oxygen species (ROS) overproduction and transmembrane glycoprotein CD98 (encoded by SLC3A2) upregulation played important roles in the initiation and progression of UC. On the basis of this, a biomimetic pH-responsive metal organic framework (MOF) carrier was constructed to deliver carbon nanodot-SOD nanozyme and clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (Cas9) (CRISPR/Cas9) system for site-specific treatment of UC. In this system, carbon nanodots (C-dots) and CD98 CRISPR/Cas9 plasmid were successfully encapsulated into MOF carrier (ZIF-8 nanoparticles) by a one-pot approach (formed as CCZ), and then camouflaged with macrophage membrane (formed as CCZM). It was worth noting that the C-dot nanozyme showed excellent superoxide dismutase (SOD) enzymatic activity, which could scavenge ROS effectively. As expected, this biomimetic system exhibited pH-responsive, immune escape, and inflammation targeting capability simultaneously. In vitro experiments showed that ROS was significantly eliminated, and CD98 was downregulated by CCZM. In the dextran sulfate sodium salt (DSS)-induced UC model, administration of CCZM significantly ameliorated the inflammation symptoms of mice, including the colon length and pathological parameters such as epithelium integrity and inflammation infiltration. In addition, both in vitro and in vivo results demonstrated that biomimetic nanoparticles effectively reduced the expression of pro-inflammatory cytokines. Overall, this study would provide a promising approach for the precise treatment of UC.

Abstract
Microwave (MW) hyperthermia has been widely studied in tumor therapy, while the lack of specificity, and the potential toxicity induced by instability or difficulty in degradation of existed MW thermal sensitizers still limits the application. Herein, a new biocompatible Poly(lactic-co-glycolic acid) (PLGA)-based nanosensitizer of Dtxl-Gd@PLGA-PEG-TPP (DGPPT) with capacities of magnetic resonance (MR) imaging and mitochondrial targeting for MW hyperthermia combined with chemotherapy was constructed via a double emulsion solvent evaporation method. The modified TPP significantly enhanced the specificity of sensitizer for targeting mitochondria, a heat-sensitive energy supply plant in cells. Thus the MW thermal damage induced by the loaded Gd in PLGA nanospheres was also strengthened. Together, the system could also achieve MR imaging due to the existence of Gd. In addition, the encapsulated Dtxl performed the chemotherapy of inhibiting mitochondrial function for assisting with MW hyperthermia. In vivo experiments demonstrated that PLGA had high biocompatibility that no obvious damage occurred even the dose was up to 200 mg/kg. Meanwhile, DGPPT+MW representing the combination of mitochondrial targeting and MW hyperthermia-chemotherapy has also been proved to shrink tumor size effectively. This study provides a new direction for building biosafe and multifunctional MW sensitizer with active targeting ability to impede tumor growth.

Abstract
Recent advances in nanotechnology have opened up new avenues for the controlled synthesis of nanoparticles for biomedical and pharmaceutical applications. Chinese herbal medicine is a natural gift to humanity, and it has long been used as an antibacterial and anticancer agent. This study will highlight recent developments in the phytonanotechnological synthesis of Chinese herbal medicines to utilize their bioactive components in biomedical and therapeutic applications. Biologically synthesized silver nanoparticles (AgNPs) have emerged as a promising alternative to chemical and physical approaches for various biomedical applications. The comprehensive rationale of combinational or synergistic effects of Chinese herb-based AgNPs synthesis was investigated with superior physicochemical and biological properties, and their biomedical applications, including antimicrobial and anticancer activity and wound healing properties. AgNPs can damage the cell ultrastructure by triggering apoptosis, which includes the formation of reactive oxygen species (ROS), DNA disintegration, protein inactivation, and the regulation of various signaling pathways. However, the anticancer mechanism of Chinese herbal medicine-based AgNPs is more complicated due to the potential toxicity of AgNPs. Further in-depth studies are required to address Chinese herbs' various bioactive components and AgNPs as a synergistic approach to combat antimicrobial resistance, therapeutic efficiency of drug delivery, and control and prevention of newly emerged diseases.

Abstract
We design multifunctional CDDP-VPA@ZrMOF-Cys-PEG nanoparticles (CVZP NPs) based on the properties of valproic acid (VPA) that can downregulate the expression of vascular endothelial growth factor (VEGF) to reduce the drug resistance of tumor cells. In vivo experiments confirm that chemotherapy combined with microwave thermal therapy (MWTT) can significantly improve the therapeutic effect of cisplatin-resistant lung cancer.
