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.

Objective:To explore the effects of information-motivation-behavior (IMB) model combined with solution focused approach (SFA) in primary large liver cancer (PLLC) .Methods:From January 2017 to January 2018, this study selected 123 PLLC patients of the Affiliated Cancer Hospital of Zhengzhou University as subjects by convenience sampling. All of patients were divided into group A ( n=61) and group B ( n=62) with the random number table. Group A carried out the routine nursing model, while group B implemented the IMB model combined with the SFA. The intervention effects were evaluated with the Quality of Life-Liver Cancer (QOL-LC) , the Chinese Strategies Used by People to Promote Health (C-SUPPH) and the Herth Hope Index (HHI) . Results:Among those PLLC patients between two groups, there were no statistical differences in the scores of QOL-LC, C-SUPPH and HHI on admission ( P>0.05) . The scores of QOL-LC, C-SUPPH and HHI of PLLC patients in group B at discharge, 15 days after discharge were higher than those in group A with statistical differences ( P<0.05) . Conclusions:In the process of clinical intervention for PLLC patients, scientific and reasonable IMB model combined with SFA based on patients' condition can improve the scores of QOL-LC, C-SUPPH and HHI which is one of the subsidiary intervention for improving the whole therapeutic effects and has good application as well as promotion values.
