Missed diagnosis can often be noted in mild traumatic brain injury (mTBI), resulting from atypical symptoms, diverse performances and subjectively dependent report. Blood biomarkers can not only reflect the pathophysiological process of mTBI to a certain extent, but also have important clinical value in assessing brain injury severity and predicting adverse outcomes. This article systematically describes the research progress of blood biomarkers that can assist mTBI diagnosis, distinguish CT manifestations and predict prognoses in recent years, aiming to provide references for clinical application of blood biomarkers in mTBI.

Energy metabolism is fundamental for life.It encompasses the utilization of carbohydrates,lipids,and proteins for internal processes,while aberrant energy metabolism is implicated in many diseases.In the present study,using three-dimensional(3D)printing from polycarbonate via fused deposition modeling,we propose a multi-nuclear radiofrequency(RF)coil design with integrated 1H birdcage and interchangeable X-nuclei(2H,13C,23Na,and 31P)single-loop coils for magnetic resonance imaging(MRI)/magnetic resonance spectroscopy(MRS).The single-loop coil for each nucleus attaches to an arc bracket that slides unrestrictedly along the birdcage coil inner surface,enabling convenient switching among various nuclei and animal handling.Compared to a commercial 1H birdcage coil,the proposed 1H birdcage coil exhibited superior signal-excitation homogeneity and imaging signal-to-noise ratio(SNR).For X-nuclei study,prominent peaks in spectroscopy for phantom solutions showed excellent SNR,and the static and dynamic peaks of in vivo spectroscopy validated the efficacy of the coil design in structural imaging and energy metabolism detection simultaneously.
