CD163 and infection: In this study, after treatment, the improvement of serum sICAM-1, sTREM-1, and sCD163 levels in the observation group was greater than that in the control group, indicating that ESWT can effectively regulate the levels of serum sICAM-1, sTREM-1, and sCD163, which may be related to the inhibition of early inflammatory response and anti-infection effect of ESWT.
