A RPF model was established on the dorsum of 92 male C57BL/6J mice aged 6-8 weeks. The flap was divided into three equal zones (zones Ⅰ, Ⅱ, and Ⅲ) from the caudal to the cephalic end. The relative temperatures (RTs, the difference between the target zones and the normal control zone) of the three zones were measured using an infrared thermal imager at postoperative day (POD) 0 (immediately), 3, and 7. At POD 3 and 7, receiver operating characteristic (ROC) curves were used to evaluate the predictive efficacy of the RT of flap zone Ⅱ for flap necrosis and to determine the optimal cutoff values. Based on the RT of flap zone Ⅱ at POD 3, mice were divided into >-0.1 ℃ group and ≤-0.1 ℃ group; based on the RT of flap zone Ⅱ at POD 7, mice were divided into >0.1 ℃ group and ≤0.1 ℃ group. The survival rate of flaps was calculated for the first two groups of mice at POD 3 and for the latter two groups of mice at POD 7. Laser Doppler perfusion imaging was used to measure blood perfusion volume of flaps in the above groups at the corresponding time points. At POD 3, the tissue of flap zone Ⅱ from >-0.1 ℃ and ≤-0.1 ℃ groups of mice was collected for transcriptomic sequencing to screen for differentially expressed genes (DEGs) with significantly differential expression, for immunofluorescence staining to calculate the ratios of inducible nitric oxide synthase (iNOS)/CD68 and arginase 1 (ARG1)/CD68, for immunohistochemical staining to detect the expression of C-C motif chemokine ligand 2 (CCL2), for dihydroethidium (DHE) staining to detect the expression of DHE, for real-time fluorescence quantitative reverse transcription polymerase chain reaction to measure the mRNA expressions of tumor necrosis factor α (TNF-α), interleukin-1β (IL-1β), and IL-10, and for Western blotting to detect the protein expressions of CD68, iNOS, ARG1, heme oxygenase-1 (HO-1), and superoxide dismutase 1 (SOD1).

While normal wound healing consists of four phases: hemostasis, inflammation, proliferation, and remodeling, diabetic wounds tend to become chronic and refractory primarily due to a prolonged inflammatory phase. In diabetic wounds, insufficient synthesis and release of endogenous calcitonin gene-related peptide (CGRP) is a critical upstream mechanism underlying the disrupted neuro-immune communication, the persistent inflammation, and the arrested wound healing process. In contrast to pure skin defect wounds, where CGRP is rapidly upregulated after injury, CGRP remains persistently low in diabetic wound tissue, consequently failing to drive macrophage polarization towards the M2 phenotype or promote vascular maturation and collagen fiber deposition in the later phase of inflammation. In the early inflammatory phase, CGRP exerts pro-inflammatory effects by enhancing angiogenesis and modulating macrophage polarization. In the late inflammatory phase, CGRP upregulates thrombospondin-1, promotes neutrophil apoptosis and phagocytic clearance, thereby inhibiting excessive inflammatory response and shifting the wound microenvironment from a pro-inflammatory state to a pro-reparative state. Restoring CGRP signaling reconstructs the neuroimmunomodulation axis and improves wound repair while relieving diabetic neuropathic pain. Engineered CGRP combined with intelligent delivery systems offers promising prospects for diabetic wound therapy. However, large-scale clinical trials are still required to validate its clinical efficacy and safety. This paper systematically analyzes the mechanisms and application strategies of CGRP in facilitating diabetic wound repair, which can provide a theoretical basis and innovative strategies for clinical management.</p>","PeriodicalId":516861,"journal":{"name":"Zhonghua shao shang yu chuang mian xiu fu za zhi","volume":"42 7","pages":"687-693"},"PeriodicalIF":0.0,"publicationDate":"2026-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13416970/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148671898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Databases including PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, and VIP Chinese Journal Service Platform were retrieved to obtain the publicly published retrospective and prospective studies on the effects of PDL combined with fractional carbon dioxide laser for pediatric HS from the establishment of each database to October 31, 2024. The outcome indexes included the total score of the patient and observer scar assessment scale (POSAS) and laser treatment-related adverse reactions. Stata version 16.0 software was used to conduct a meta-analysis. <b>Results:</b> A total of 7 studies were included, involving 348 children with HSs. Meta-analysis results showed that the total POSAS scores in HS children who received PDL combined with fractional carbon dioxide laser treatment were significantly lower than those before treatment (with a standardized mean difference of -7.76, a 95% <i>CI</i> of -10.91 to-4.61, <i>P</i><0.05). Subgroup analysis results suggested that geographic distribution, scar duration (divided into ≤3 months group and >3 months group), intervention measures, and fractional carbon dioxide laser energy parameters might be sources of heterogeneity for the total POSAS score. The incidence of adverse reactions of PDL combined with fractional carbon dioxide laser for pediatric HS was 3.50% (with a 95% <i>CI</i> of 1.60% to 6.00%, <i>P</i><0.05). There was no publication bias in the total POSAS score, its subgroup analyses (including geographic distribution, scar duration, intervention measures, fractional carbon dioxide laser energy parameters, and assessor), or adverse reactions related to laser treatment (<i>P</i>>0.05). <b>Conclusions:</b> PDL combined with fractional carbon dioxide laser is beneficial for the recovery of pediatric HS, with a low rate of adverse reactions and a favorable safety profile. For pediatric HS, the early intervention window within 3 months after scar formation should be prioritized, and a regimen combining low-energy fractional carbon dioxide laser flexibly with PDL should be adopted to achieve better therapeutic outcomes.</p>","PeriodicalId":516861,"journal":{"name":"Zhonghua shao shang yu chuang mian xiu fu za zhi","volume":"42 7","pages":"679-686"},"PeriodicalIF":0.0,"publicationDate":"2026-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13416978/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148671945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
