his study provides the first clinical evaluation of the combined use of microneedling and PRX PLUS for multidimensional skin quality improvement. By integrating objective imaging-based assessments (VISIA® and Visioscope) with patient-reported outcomes, the study demonstrates potential benefits of this minimally invasive approach in improving skin texture, pigmentation, redness, pore visibility, and overall facial appearance. These findings provide preliminary clinical evidence supporting regenerative, low-downtime strategies for skin rejuvenation and highlight the need for further controlled studies to validate the efficacy and underlying mechanisms of this combined protocol.

With the advancement of long-term crewed deep-space exploration missions, the effects of the microgravity environment on astronauts' brain function have become an important topic in aerospace medicine. The disappearance of the hydrostatic pressure gradient during spaceflight induces cephalad fluid shifts, which can alter cerebral blood flow (CBF) and are closely associated with visual impairment, spatial disorientation, and cognitive decline. However, existing studies have predominantly focused on the steady-state phase during the middle and late stages of microgravity exposure, with insufficient understanding of the characteristics of CBF fluctuations during the early phase of postural transitions. Moreover, as an indicator of terminal perfusion in the cerebral microcirculation, the coupling relationship between CBF and the upstream hemodynamics of the internal carotid and vertebral arteries has not been systematically investigated. In addition, magnetic resonance imaging (MRI) cannot be applied in real time during spaceflight due to its bulky equipment, whereas ultrasound offers the advantages of portability, real-time capability, and radiation-free operation. Therefore, elucidating the association between early macrovascular hemodynamic changes under simulated microgravity and regional CBF alterations, and evaluating the feasibility of using ultrasound parameters as portable predictors of CBF, holds significant scientific importance and application value.
