Magnetic stimulation has made significant strides in the treatment of psychiatric disorders. Nonetheless, current magnetic stimulation techniques lack the precision to accurately modulate specific nuclei and cannot realize deep brain magnetic stimulation. To address this, we utilized superparamagnetic iron oxide nanoparticles as mediators to achieve precise targeting and penetration. We investigated the effects of magnetic fields with varying frequencies on neuronal activity and compared the activation effects on neurons using a 10-Hz precise magneto-stimulation system (pMSS) with repetitive transcranial magnetic stimulation in mice. Oxytocin levels, dendritic morphology and density, and mouse behavior were measured before and after pMSS intervention. Our findings suggest that pMSS can activate oxytocinergic neurons, leading to upregulation of oxytocin secretion and neurite outgrowth. As a result, sociability was rapidly improved after a one-week pMSS treatment regimen. These results demonstrate a promising magneto-stimulation method for regulating neuronal activity in deep brain nuclei and provide a promising therapeutic approach for autism spectrum disorder.

Traumatic injuries represent the fifth leading cause of death in China and the primary cause of death among young adults. While facial fractures can lead to significant aesthetic and psychological consequences, fractures in the limbs and joints impair functional mobility. In traumatic incidents requiring forensic evaluation, such as traffic accidents or violent conflicts, the type and severity of fractures directly determine injury grading and disability assessment. Consequently, the accurate diagnosis of traumatic fractures is not only a critical medical issue impacting patient management and rehabilitation but also a significant social issue influencing judicial fairness. This article systematically reviews advancements in multi-modal imaging techniques. While conventional X-ray radiography remains a fundamental screening tool, it faces challenges in detecting occult fractures. Multi-slice spiral computed tomography (MSCT), utilizing 3D reconstruction, enables spatial analysis of complex fractures. Magnetic resonance imaging (MRI), with its multi-sequence capabilities, plays an indispensable role in detecting bone marrow edema and assessing concomitant soft tissue injuries. Regarding innovative technologies, dual-energy computed tomography (DECT) employs virtual non-calcium (VNC) techniques for quantitative bone marrow edema analysis; ultra-high-resolution computed tomography (U-HRCT) breaks through imaging limitations of trabecular microarchitecture with a resolution of approximately 10 μm; and 7.0 T ultra-high-field MRI, alongside MRI-based CT-like imaging techniques, advances radiation-free bone structure evaluation. Artificial intelligence (AI) models significantly enhance diagnostic efficiency in fracture detection. Future developments will focus on multi-modal image fusion, the construction of intelligent decision-support systems, and the quantitative functional assessment of bone microstructure, facilitating a paradigm shift from anatomical description to prognostic prediction and realizing the principles of personalized medicine.

Objective:To investigate effects of the ROCK1 gene on proliferation and migration of and related molecular expression in keloid fibroblasts.Methods:Immunohistochemical technique was used to detect ROCK1 protein expression in human keloids and normal skin tissues, and Western blot analysis was performed to detect the expression of ROCK1, transforming growth factor β1 (TGF-β1) and E-cadherin in keloid tissues. In vitro cultured human keloid fibroblasts (HKFs) were divided into 4 groups: ROCK1 gene overexpression control group (ROCK1 NC group) transfected with ROCK1 gene overexpression control vectors, ROCK1 gene overexpression group (ROCK1 OE group) transfected with ROCK1 gene overexpression vectors, ROCK1 gene knockdown control group (sh NC group) transfected with ROCK1 gene knockdown control vectors, and ROCK1 gene knockdown group (shROCK1 group) transfected with ROCK1 gene knockdown vectors. Cell counting kit-8 (CCK8) assay was performed to evaluate the effect of ROCK1 gene on the survival rate of HKFs, Transwell assay to evaluate the effect on the migration of HKFs, and real-time fluorescence-based quantitative PCR (qRT-PCR) and Western blot analysis were conducted to determine the mRNA and protein expression of ROCK1, TGF-β1 and E-cadherin, respectively. Results:Immunohistochemical study showed that ROCK1 protein expression decreased significantly in the human keloid tissues compared with the normal tissues ( t = 6.47, P = 0.003) ; Western blot analysis showed that the expression levels of ROCK1 and E-cadherin significantly decreased ( t = 14.02, 162.20, respectively, both P < 0.001), while TGF-β1 expression significantly increased ( t = 76.01, P < 0.001) in the keloid tissues compared with the expression levels of corresponding proteins in the normal tissues. CCK8 assay showed that the cell activity was significantly lower in the ROCK1 OE group than in the ROCK1 NC group after 24-hour transfection ( t = 3.25, 3.78, P = 0.031, 0.019, respectively), and significantly higher in the shROCK1 group than in the sh NC group ( t = 3.12, 2.79, P = 0.036, 0.049, respectively). Transwell assay showed that the number of migratory cells was significantly lower in the ROCK1 OE group than in the ROCK1 NC group ( t = 5.17, P = 0.004), and significantly higher in the shROCK1 group than in the sh NC group ( t = 9.28, P < 0.001). Compared with the ROCK1 NC group, the ROCK1 OE group showed significantly increased mRNA and protein expression levels of ROCK1 and E-cadherin ( P < 0.05 or < 0.001), but decreased mRNA and protein expression levels of TGF-β1 (both P < 0.001) ; compared with the sh NC group, the shROCK1 group showed significantly decreased mRNA and protein expression levels of ROCK1 and E-cadherin ( P < 0.05 or < 0.001), but significantly increased mRNA and protein expression levels of TGF-β1 ( P = 0.005 or < 0.001) . Conclusions:The ROCK1 gene can inhibit the proliferation and migration of HKFs. Overexpression of the ROCK1 gene can down-regulate the TGF-β1 gene expression and up-regulate the E-cadherin gene expression in HKFs.

There was no significant difference between the two methods at different time points after operation, and the incidence of complications in the study group was less than that in the control group at 1 week after operation.Conclusions:Combined with fascial sheath suspension and levator palpebrae muscle complex tension-free shortening in the treatment of severe blepharoptosis has less complications and reliable curative effect in the early postoperative period, but it still needs to be improved to obtain more lasting curative effect.

OBJECTIVE: To build a physiological aging scale for healthy people.
 METHODS: We collected age-related physiologic items through literature screening and expert interview. Two rounds of Delphi were implemented. The importance, feasibility and the degree of authority for the physiological index system were graded. Using analytic hierarchy process, we determined the weight of dimensions and items.
 RESULTS: Using Delphy mothod, 17 physiological and other professional experts offered the results as follow: coefficient of expert authorities Cr was 0.86±0.03, coordination coefficients for the first and second round were 0.264(χ2=229.691, P<0.001) and 0.293(χ2=228.474，P<0.001), respectively. The consistency was good. The aging scale for healthy people included 3 dimensions, namely physical form, feeling movement and functional status. Each dimension had 8 items. The weight coefficients for the 3 dimensions were 0.54, 0.16, and 0.30, respectively. The Cronbach's α coefficient of the scale was 0.893, the reliability was 0.796, and the variance of the common factor was 58.17%.
 CONCLUSION The improved Delphi method or physiological aging scale is satisfied, which can provide reference for the evaluation of aging.
