Research progress on wearable physiological parameter monitoring and its clinical applications / 生物医学工程学杂志

Wearable physiological parameter monitoring devices play an increasingly important role in daily health monitoring and disease diagnosis/treatment due to their continuous dynamic and low physiological/psychological load characteristics. After decades of development, wearable technologies have gradually matured, and research has expanded to clinical applications. This paper reviews the research progress of wearable physiological parameter monitoring technology and its clinical applications. Firstly, it introduces wearable physiological monitoring technology's research progress in terms of sensing technology and data processing and analysis. Then, it analyzes the monitoring physiological parameters and principles of current medical-grade wearable devices and proposes three specific directions of clinical application research: 1) real-time monitoring and predictive warning, 2) disease assessment and differential diagnosis, and 3) rehabilitation training and precision medicine. Finally, the challenges and response strategies of wearable physiological monitoring technology in the biomedical field are discussed, highlighting its clinical application value and clinical application mode to provide helpful reference information for the research of wearable technology-related fields.

Effects of entecavir on serum HBV DNA load and transformer growth factor-β(1) in patients with chronic hepatitis B / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate the changes in serum hepatitis B viral load (HBV DNA) and transformer growth factor-β(1)(TGF-β1) in patients with chronic hepatitis B after entecavir treatment and evaluates the therapeutic effect of entecavir.</p><p><b>METHODS</b>Sixty-three patients with chronic hepatitis B were randomly assigned into entecavir group (n=33) and control group (n=30). The entecavir group consisted of 9 mild, 17 moderate, and 7 severe cases, all treated with oral entecavir (0.5 mg daily) and general hepatoprotective drugs; the control group, consisting of 13 mild, 12 moderate and 5 severe cases, was treated with the hepatoprotective drugs only. Serum HBV DNA and TGF-β(1)were determined before and at 3 and 6 months during the treatment.</p><p><b>RESULTS</b>Entecavir treatment reduced serum HBV DNA load in all the cases in entecavir group, and the difference was statistically significant between the levels measured at 3 and 6 months (P<0.05). The treatment also resulted in decreased serum TGF-β(1)levels in moderate and severe cases, and the severe cases showed a significant TGF-β(1)reduction after a 6-month treatment (P<0.05).</p><p><b>CONCLUSION</b>Entecavir can lower serum HBV DNA load levels in patients with chronic hepatitis B. Entecavir is also effective to reduce serum TGF-β(1)levels in moderate and severe cases, especially in the latter.</p>
