Surface modification of multifunctional ferrite magnetic nanoparticles and progress in biomedicine / 生物医学工程学杂志

Magnetic ferrite nanoparticles (MFNPs) have great application potential in biomedical fields such as magnetic resonance imaging, targeted drugs, magnetothermal therapy and gene delivery. MFNPs can migrate under the action of a magnetic field and target specific cells or tissues. However, to apply MFNPs to organisms, further modifications on the surface of MFNPs are required. In this paper, the common modification methods of MFNPs are reviewed, their applications in medical fields such as bioimaging, medical detection, and biotherapy are summarized, and the future application directions of MFNPs are further prospected.

Evidence summary of exercise rehabilitation for heart transplantion patients / 中国实用护理杂志

Objective:To search and analyze the relevant evidence of exercise rehabilitation in heart transplant patients and summarize the best evidence.Methods:The best practice information book, evidence summary, guidelines, expert consensus and systematic review of exercise rehabilitation for heart transplant patients in CNKI, Wanfang, CBM, PubMed, Embase, Cochrane Library, UpToDate, BMJ Best Practjce, National Institute for Health and Clinical Excellence (NICE), International Guidelines Network (GIN), Scottish Intercollegiate Guidelines Network (SIGN), New England Medicine (NEJM), Joanna Briggs Institute (JBI) Evidence-based Health Care Center in Australia, American Health Care Policy Research Institute (AHRQ), American Heart Association (AHA), American College of Cardiology (ACC), American Association for Cardiopulmonary Rehabilitation (AACVPR), European Society of Cardiology (ESC), International Society for Heart and Lung Transplantation (ISHLT) were searched by computer.Results:A total of 10 articles were included, including 1 clinical decision, 2 guidelines, 1 expert consensus and 6 systematic reviews; after evaluation, a total of 21 best evidences in 7 aspects: exercise effectiveness, exercise timing, exercise assessment, exercise modality, exercise duration, pre-habilitation, exercise compliance were summarized.Conclusions:This study summarizes the best evidence of exercise rehabilitation in patients undergoing heart transplantation and provides a reference for medical staff to develop exercise rehabilitation programs for patients after heart transplantation.

Application of organic fluorescent probe-assisted near infrared fluorescence imaging in cervical cancer diagnosis / 生物工程学报

Fluorescence imaging has been widely used in the fields of biomedicine and clinical diagnosis. Compared with traditional fluorescence imaging in the visible spectral region (400-760 nm), near-infrared (NIR, 700-1 700 nm) fluorescence imaging is more helpful to improve the signal-to-noise ratio and the sensitivity of imaging. Highly-sensitive fluorescent probes are required for high-quality fluorescence imaging, and the rapid development of nanotechnology has led to the emergence of organic dyes with excellent fluorescent properties. Among them, organic fluorescent probes with the advantages of high safety, good biocompatibility, and high optical stability, are more favorable than inorganic fluorescent probes. Therefore, NIR fluorescence imaging assisted with organic fluorescent probes can provide more structural and dynamic information of biological samples to the researchers, which becomes a hot spot in the interdisciplinary research field of optics, chemistry and biomedicine. This review summarizes the application of NIR organic fluorescent probes in cervical cancer imaging. Several typical organic fluorescent probes (such as indocyanine green, heptamethine cyanine dye, rhodamine and polymer fluorescent nanoparticles) assisted NIR fluorescence imaging and their applications in cervical cancer diagnosis were introduced, and the future development and application of these techniques were discussed.
