摘要Recent evidence suggests that low-intensity extracorporeal shock wave therapy(Li-ESWT)is a promising treatment for chronic prostatitis/chronic pelvic pain syndrome(CP/CPPS);however,its safety in pelvic organs,particularly prostate tissues and cells,remains unclear.The current study evaluates the risks of prostate cell damage or oncogenesis following the administration of Li-ESWT for prostatitis.To this end,a robust in vitro model(Cell Counting Kit-8[CCK-8]assay,clone formation assay,cell scratch assay,lactate dehydrogenase[LDH]release assay,flow cytometry,and immunoblotting assay)was designed to examine the effects of Li-ESWT on cell proliferation,clonogenicity,migration,membrane integrity,and DNA damage.Exome sequencing of Li-ESWT-treated cells was performed to determine the risk of carcinogenesis.Furthermore,an in vivo rat model(n=20)was employed to assess the effects of Li-ESWT on cancer biomarkers(carcinoembryonic antigen[CEA],Ki67,proliferating cell nuclear antigen[PCNA],and gamma-H2A histone family member X,phosphorylation of the H2AX Ser-139[y-H2AX])in prostate tissue.Based on our findings,Li-ESWT promotes cellular growth and motility without inducing significant cell membrane or DNA damage or alterations.Genetic analyses did not demonstrate an increase in mutations,and no damage to prostate tissue or upregulation of cancer biomarkers was detected in vivo.This comprehensive in vitro and in vivo assessment confirms the safety of Li-ESWT in managing prostate disorders.
