Synergizing Digital and Physical Approaches: Experience Summary of the HIV PrEP Promotion Project.

China's human immunodeficiency virus / acquired immune deficiency syndrome (HIV/AIDS) prevention and control efforts have entered a new stage, necessitating the exploration of more effective intervention strategies. HIV pre-exposure prophylaxis (PrEP) is a proven method to prevent HIV infection, but its promotion in China faces challenges such as low public acceptance and inadequate service capacity. To further promote PrEP, the "HIV PrEP Model Exploration Project" was launched, exploring three PrEP service models: PrEP clinics, Digital services and physical testing, and PrEP self-service vending machines.

Research on the Performance of a Liquid-Solid Triboelectric Nanogenerator Prototype Based on Multiphase Liquid.

In recent years, liquid-solid triboelectric nanogenerators (L-S TENGs) have been rapidly developed in the field of liquid energy harvesting and self-powered sensing. This is due to a number of advantages inherent in the technology, including the low cost of fabricated materials, structural diversity, high charge-energy conversion efficiency, environmental friendliness, and a wide range of applications. As liquid phase dielectric materials typically used in L-S TENG, a variety of organic and inorganic single-phase liquids, including distilled water, acidic solutions, sodium chloride solutions, acetone, dimethyl sulfoxide, and acetonitrile, as well as paraffinic oils, have been used in experiments.

Tumor microenvironment-responsive engineered hybrid nanomedicine for photodynamic-immunotherapy via multi-pronged amplification of reactive oxygen species.

Reactive oxygen species (ROS) is promising in cancer therapy by accelerating tumor cell death, whose therapeutic efficacy, however, is greatly limited by the hypoxia in the tumor microenvironment (TME) and the antioxidant defense. Amplification of oxidative stress has been successfully employed for tumor therapy, but the interactions between cancer cells and the other factors of TME usually lead to inadequate tumor treatments. To tackle this issue, we develop a pH/redox dual-responsive nanomedicine based on the remodeling of cancer-associated fibroblasts (CAFs) for multi-pronged amplification of ROS (ZnPP@FQOS).

Trojan Horse Strategy for Wireless Electrical Stimulation-Induced Zn Release to Regulate Neural Stem Cell Differentiation for Spinal Cord Injury Repair.

Due to the uncertain differentiation of neural stem cells (NSCs), replenishing lost neurons by endogenous neural differentiation to repair spinal cord injury (SCI) remains challenging.
