摘要(中文译文)

本研究系统梳理了2014年至2024年间发表的小分子辐射医学防护剂(RMCs)小鼠体内研究,并聚焦于与造血型急性辐射综合征(H-ARS)相关的全身照射或全淋巴照射(WBI/TBI)模型开展定量生存分析。小鼠模型在辐射生物学中具有核心地位,因其可提供受控、可重复的系统,用于研究辐射损伤、测试候选治疗药物并生成与临床转化相关的临床前证据。通过结构化PubMed检索共识别出5558条记录,其中258项研究符合纳入标准。提取了研究特征与结局,并对生存研究按全身照射或全淋巴照射、适宜剂量范围、Kaplan-Meier报告及数据完整性进行筛选。为减少异质性,荟萃分析仅限于暴露于7.5-9.5 Gy全身照射的C57BL/6小鼠。在118项生存研究中,48个队列符合条件,但仅8.0-8.5 Gy和8.5-9.0 Gy剂量范围支持定量合成。采用限制性平均生存时间(RMST;τ=30天)进行合并分析显示,与对照队列相比,治疗队列的生存获益分别为12天和13天。多种化学结构不同的辐射医学防护剂均改善了生存,其中δ-生育三烯酚衍生物的效应最大。这些发现既凸显了小鼠模型的转化价值,也表明需要在实验设计和报告方面实现更高程度的标准化。

Abstract

This study systematically maps murine in vivo research on small-molecule radiation medical countermeasures (RMCs) published between 2014 and 2024, with quantitative survival analysis focused on whole or total-body irradiation (WBI/TBI) models relevant to hematopoietic acute radiation syndrome (H-ARS). Murine models are central to radiation biology because they provide controlled, reproducible systems for studying radiation injury, testing candidate therapeutics, and generating preclinical evidence relevant to clinical translation. A structured PubMed search identified 5,558 records, of which 258 studies met inclusion criteria. Study characteristics and outcomes were extracted, and survival studies were filtered for (WBI/TBI), appropriate dose range, Kaplan-Meier reporting, and data integrity. To reduce heterogeneity, meta-analysis was restricted to C57BL/6 mice exposed to 7.5-9.5 Gy WBI. Of 118 survival studies, 48 cohorts were eligible, but only the 8.0-8.5 Gy and 8.5-9.0 Gy dose ranges supported quantitative synthesis. Using restricted mean survival time (RMST; τ = 30 days), pooled analysis showed survival gains of 12 and 13 days, respectively, in treated versus control cohorts. Multiple chemically distinct RMCs improved survival, with the largest effects observed for delta-tocotrienol derivatives. These findings highlight both the translational value of murine models and the need for greater standardization in experimental design and reporting.
