2.6. Observation Criteria

General Information. The general information extract form was established by the patients themselves, covering the inpatient number, name, gender, age, body mass, causes of burn, burn area, burn type, burn site, place of residence, and educational level.

Wound Healing. ① Wound healing time: the time from being injured to complete epithelization of wound; ② wound healing rate: mean wound healing rate = (wound area immediately after injury − wound area at each time phase)/wound area immediately after injury × 100%; ③ wound healing quality: the Vancouver scar scale (VSS) [13] was used as the basis for evaluating the color, thickness, vascularity, softness of the scar area after the wound was healed, and on a scale of 0–15 points, higher scores indicated more serious scars.

ARR. The adverse reactions occurred in patients of the two groups during treatment were recorded.

Levels of Inflammatory Factors. The patients' fasting venous blood in the morning was drawn before treatment (T₁), 3 days after treatment (T₂) and 7 days after treatment (T₃) to measure their C-reactive protein (CRP) levels with immunoturbidimetry (kits manufactured by Nanjing Getein Biotech Inc., Jiangsu Changzhou MPA certification no. 20122400146) and TNF-α, IL-1, and IL-8 levels with chemiluminescence immunoassay (Cobase 411 analyzer with original supporting agents; NMPA (I) 20113402843).

Incidence Rate of Infections. The infections included marginal cellulitis, empyema under scab, newborn tissue necrosis, and others, and the numbers of patients with infections were counted.
