Reducing the secondary.inflammatory.response, which is partly.mediated by.microglia, is a key.focus in the treatment of spinal cord injury. Src homology.2-containing protein ty.osine phosphatase 2(SHP2), encoded by.PTPN11, is widely.expressed in the human body.and play. a role in inflammation through various mechanisms. Therefore, SHP2 is considered a potential target for the treatment of inflammation-related diseases. However, its role in secondary.inflammation after spinal cord injury.remains unclear. In this study. SHP2 was found to be abundantly.expressed in microglia at the site of spinal cord injury. Inhibition of SHP2 expression using siRNA and SHP2 inhibitors attenuated the microglial inflammatory.response in an in vitro lipopoly.accharide-induced model of inflammation. Notably. after treatment with SHP2 inhibitors, mice with spinal cord injury.exhibited significantly.improved hind limb locomotor function and reduced residual urine volume in the bladder. Subsequent in vitro experiments showed that, in microglia stimulated with lipopoly.accharide, inhibiting SHP2 expression promoted M2 polarization and inhibited M1 polarization. Finally. a co-culture experiment was conducted to assess the effect of microglia treated with SHP2 inhibitors on neuronal cells. The results demonstrated that inflammatory.factors produced by.microglia promoted neuronal apoptosis, while inhibiting SHP2 expression mitigated these effects. Collectively. our findings suggest that SHP2 enhances secondary.inflammation and neuronal damage subsequent to spinal cord injury.by.modulating microglial phenoty.e. Therefore, inhibiting SHP2 alleviates the inflammatory.response in mice with spinal cord injury.and promotes functional recovery.postinjury.

This study.aims to develop a chloride diffusion simulation method that considers the hy.ration microstructure and pore solution properties during the hy.ration of tricalcium silicate(C3S).The method combines the hy.ration simulation,thermody.amic calculation,and finite element analy.is to examine the effects of pore solution,including effect of electrochemical potential,effect of chemical activity.and effect of mechanical interactions between ions,on the chloride effective diffusion coefficient of hy.rated C3S *** results indicate that the effect of electrochemical potential on chloride diffusion becomes stronger with increasing hy.ration age due to the increase in the content of hy.rated calcium silicate;as the hy.ration age increases,the effect of chemical activity.on chloride diffusion weakens when the number of diffusible elements decreases;the effect of mechanical interactions between ions on chloride diffusion decreases with the increase of hy.ration age.
