研究目的:

感染后机化性肺炎(PIOP)是临床常见的肺部疾病,目前治疗方法有限。前期研究发现,雾化吸入人脐带间充质干细胞外泌体(HUCMSCs-Exo)对PIOP患者有良好疗效,但作用机制尚不清楚。本项目将探索HUCMSCs-Exo作为新型治疗手段,在PIOP修复中的作用机制。并进一步评估HUCMSCs-Exo治疗PIOP的安全性和有效性。同时优化HUCMSCs-Exo纯化方法,建立更贴合人类疾病的动物模型。 临床研究部分 主要研究目的:评价HUCMSCs-Exo雾化吸入治疗PIOP患者的安全性。 次要研究目的:评价HUCMSCs-Exo雾化吸入治疗PIOP患者的有效性。  

Objectives of Study:

Post-infectious organizing pneumonia (PIOP) is a clinically common pulmonary disorder with limited treatment options. Preliminary studies have demonstrated the therapeutic potential of nebulized human umbilical cord mesenchymal stem cell-derived exosomes (HUCMSC-Exos) in PIOP patients, though the underlying mechanisms remain unclear. This project aims to: 1. Investigate the mechanistic role of HUCMSC-Exos in PIOP tissue repair; 2. Systematically evaluate the safety and efficacy of HUCMSC-Exo therapy for PIOP; 3. Optimize HUCMSC-Exo purification protocols and establish more clinically relevant animal models. Primary Objective To assess the safety profile of nebulized HUCMSC-Exos in PIOP patients. Secondary Objective To evaluate the treatment efficacy of nebulized HUCMSC-Exos in PIOP patients.

随机方法(请说明由何人用什么方法产生随机序列):

由与本研究数据管理和统计分析无关的统计学家,在计算机上用SAS统计软件包产生随机数字,按试验组与对照组1:1的比例产生随机编码,采用随机区组,每组(block)包括1个外泌体治疗和1个安慰剂;根据此随机数由与本试验无关的统计人员对药物进行编码;随机系统保持24小时开放;研究期间根据病例入组次序选择相应编号的药物依次使用。

Randomization Procedure (please state who generates the random number sequence and by what method):

Randomization Procedure ? An independent statistician (uninvolved in data management or analysis) generated random numbers using SAS software, with 1:1 allocation to the experimental (exosome treatment) and control (placebo) groups. ? Block randomization was employed, with each block containing 1 exosome and 1 placebo assignment. ? Drug coding was performed by separate statistical personnel not participating in the trial. ? The randomization system remained accessible 24/7. ? Investigators sequentially administered medications according to the pre-assigned codes based on enrollment order.
