Article Abstract
Gouty arthritis is one of the most common forms of inflammatory arthritis and has brought a significant burden on patients and society. Current strategies for managing gout primarily focus on long-term urate-lowering therapy. With the rapid advancement of point-of-care testing (POCT) technology, continuous monitoring of gout-related biomarkers like uric acid (UA) or inflammatory cytokines can provide rapid and personalized diagnosis for gout management. In this study, a plug-in design of a microneedle electrode array (PIMNA) was developed and integrated into a multi-parameter sensing portable system in combination with embedded circuits and a mobile application. The system enabled real-time, in situ, and dynamic monitoring of biomarkers, including UA, reactive oxygen species (ROS), and pH at gouty joints. The multi-parameter monitoring system demonstrated a wide linear response range, excellent selectivity, stability, reproducibility, and reliable signal transmission performance. In vivo experiments demonstrated the real-time monitoring capability of PIMNA for UA, ROS, and pH, showing the potential to facilitate urate-lowering management and inflammation assessment. Prospectively, the system enables quantitative analysis of the complexity and diversity of gout, presenting promising applications in clinical practice. This work provides a unique strategy with potential for broader applications in gout management and arthritic disease treatment.

Microneedle-based electrochemical sensors (MES) are developed as interface systems between the sensor and interstitial fluid (ISF), allowing the transdermal monitoring of analytes with clinical value. However, the widespread adoption of MES platforms to enable advances in devices for health monitoring is still a challenge. Herein, we propose an affordable and versatile wearable patch based on 3D-printed microneedle arrays to facilitate the development of electrochemical sensors.

This paper proposes an innovative double power-enhanced testing procedure for inference on high-dimensional linear hypotheses in high-dimensional regression models. Through a projection approach that aims to separate useful inferential information from the nuisance one, our proposed test accurately accounts for the impact of high-dimensional nuisance parameters. We discover that with a carefully-designed projection matrix, the projection procedure enables us to transform the problem of interest into a test on moment conditions, from which we construct a -statistic-based test that is applicable in simultaneous inference on a diverging number of linear hypotheses.

Under the background of increasing social competition pressure and health awareness, health anxiety among college students is becoming more and more prominent, which seriously affects their physical and mental health and quality of life. This study aimed to explore the relationship between physical activity, emotion regulation, stress perception, and health anxiety among college students, and to examine the mediating roles of emotion regulation and stress perception in the process of physical activity affecting health anxiety, to provide a theoretical basis for interventions targeting college students' physical activity behaviors. In this study, a cross-sectional design was used to administer questionnaires to 518 academics from Ningxia University using four questionnaires, namely, Physical Activity Rating Scale, Emotional Regulation Scale, Stress Perception Scale, and Health Anxiety Scale.

Deep learning has advanced rapidly, but relies heavily on large-labeled datasets for effective training. This is particularly challenging in fields like medicine, where expert labeling is costly, labor-intensive, and prone to bias and error. Semi-supervised learning (SSL) addresses this challenge by reducing reliance on labeled data.
