This study is a randomized, blank-controlled, open-label, single-dose, dose-escalation clinical study of rhKGF-2 in patients with ARDS. The trial is designed with three dose groups (5 mg, 10 mg, and 15 mg), which will be escalated sequentially from the lowest dose group to the highest dose group. Each dose group will enroll 8 subjects, randomized in a 6:2 ratio according to the order of enrollment, to receive either the corresponding dose of rhKGF-2 (6 subjects) or serve as a blank control (2 subjects). Each subject will receive a single dose, administered once via a disposable bronchoscopic catheter. All subjects will receive the trial intervention on top of standard ARDS treatment (see Concomitant Medications for details). Following the completion of drug administration, subjects will enter a 28-day follow-up period. Outcome measures include adverse events (AE), vital signs, laboratory parameters, oxygenation index (PFR), chest imaging changes, etc., to evaluate the safety, tolerability, and efficacy of the treatment.
