Clinical outcomes included wound healing time, wound coverage rates at 2 and 3\u2009weeks, bacterial culture positivity, and Vancouver Scar Scale scores at 3\u2009months. Wound tissue and exudate samples were collected at predefined time points for immunohistochemical analysis of macrophage phenotypes (M1\/M2) and quantification of growth factors (VEGF, PDGF, TGF\u2010\u03b2).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Compared with the control group, PRP treatment was associated with a shorter wound healing time, increased early wound coverage, reduced bacterial culture positivity, and improved scar outcomes. Early PRP intervention and the use of leukocyte\u2010poor PRP appeared to further enhance healing efficiency, which may be related to accelerated polarization of macrophages from the pro\u2010inflammatory M1 phenotype toward the anti\u2010inflammatory M2 phenotype. In contrast, high\u2010frequency PRP administration resulted in higher local growth factor levels but did not translate into additional clinical benefit; this lack of efficacy may be attributable to excessive expression of transforming growth factor\u2010\u03b2 (TGF\u2010\u03b2), which could potentially counteract optimal tissue repair.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>PRP is an effective adjunctive therapy for small\u2010area deep second\u2010degree burns. Early application and leukocyte\u2010poor PRP appear optimal, whereas indiscriminately increasing treatment frequency is not recommended.
