Stroke ranks as the fourth leading cause of death in Hong Kong. Between 2001 and 2021 there was a distinct trend towards younger onset ages of stroke, which has exerted a profound impact on the public health system and the families of patients. To address the challenges of disability and slow rehabilitation progress associated with hemiparesis, a common sequela of stroke, a research team at The Hong Kong Polytechnic University (PolyU) has applied intelligent closed-loop mobile technology to develop a new-generation wearable rehabilitation device, the “Remind-to-Move” (RTM) sensory wristband. Complemented by a mobile application, the device delivers instant feedback to users and automatically adjusts treatment regimens, thereby enabling more personalised home-based rehabilitation training.

Recently, the team led by Professor Jinzhong Ma and Tao Wang at Shanghai General Hospital, in collaboration with Professor Guoqing Pan at Jiangsu University, conducted a systematic review on this topic, comprehensively summarizing the latest advances and advancing the development and application of photodynamic antibacterial strategies for titanium implants.

Researchers found that toxic metal particles in rural North China air are smaller and potentially more harmful than those in urban areas. The study showed that village pollution was strongly linked to biomass and coal burning, while urban pollution was mainly associated with dust-related mineral particles. The findings highlight the overlooked health risks faced by rural populations exposed to PM_2.5-bound heavy metals.

Xuebijing injection (XBJ), a clinically widely used traditional Chinese medicine formulation, ameliorates LPS-induced acute lung injury (ALI) through multi-target synergy. It inhibits inflammation and ferroptosis by directly binding to five key proteins (PKM2, ENO1, PBK, EIF3I, Keap1), suppressing the MAPK/NF-κB/NLRP3 signaling axis, restoring alveolar barrier integrity and immune homeostasis, providing new mechanistic evidence and therapeutic prospects for ALI treatment.

A research team has mapped how artificial intelligence is beginning to reshape cardiac arrest care, from early warning and emergency response to cardiopulmonary resuscitation and recovery after survival. By reviewing 114 studies involving more than 9.57 million patients, the study shows that artificial intelligence is most often used to predict cardiac arrest, guide resuscitation decisions, and estimate post-arrest outcomes. The findings suggest that artificial intelligence could become a practical tool for identifying high-risk patients earlier, supporting time-critical decisions during resuscitation, and improving post-arrest care, while also highlighting the need for stronger real-world validation before these tools can be widely adopted in emergency medicine.

New study suggests using human urine as a fertiliser could significantly boost sustainable agriculture – but key health risks and knowledge gaps must be addressed before it could be widely adopted.

Researchers publishing in Computational Biomedicine have introduced a novel multi-modal artificial intelligence framework, “MediHerb,” designed to improve disease inference through Traditional Chinese Medicine (TCM) knowledge integration. The study highlights how combining biomedical data, molecular information, and herbal prescription knowledge may advance interpretable AI-driven healthcare models.

This review highlights spider silk as a next-generation eco-smart biomaterial with broad potential across dermatology, cosmetics, aerospace, textiles, and electronics. Owing to its exceptional strength, elasticity, biodegradability, biocompatibility, and low immunogenicity, spider silk is increasingly explored for wound healing, tissue regeneration, drug delivery, scar repair, and smart dermatologic theranostics. In cosmetics, its amino acid-rich structure supports skin hydration, elasticity, and barrier repair. Beyond healthcare, its lightweight strength, thermal stability, optical clarity, and flexibility enable applications in advanced composites, biodegradable sensors, and wearable devices, making spider silk a promising sustainable material for future industries.
