摘　　要：目的探讨成人骨髓增生异常综合征(myelodysplastic syndrome,MDS)单倍型造血干细胞移植后急性移植物抗宿主病(acute graft-versus-host disease,aGVHD)的预警模型构建。方法纳入2021年1月至2023年1月空军军医大学第二附属医院50例接受单倍型造血干细胞移植成人MDS患者资料,将治疗后发生aGVHD的患者纳入发生组,未发生aGVHD的患者纳入未发生组。收集、分析患者临床资料,通过Logistic回归分析法确定单倍型造血干细胞移植后发生aGVHD的影响因素,利用确定的独立影响因素构建列线图预警模型并评判单倍型造血干细胞移植后发生aGVHD的列线图预测模型效能。结果共50例成人MDS患者在本院接受单倍型造血干细胞移植治疗,发生aGVHD的患者比例为30%(15/50),未发生aGVHD的患者比例为70.00%(35/50)。Logistic回归分析结果显示,供者性别、种族、C-反应蛋白是成人MDS患者单倍型造血干细胞移植后发生aGVHD的危险因素(OR>1,P<0.05),尿酸是成人MDS患者单倍型造血干细胞移植治疗后发生aGVHD的保护因素(OR<1,P<0.05)。采用确定的独立影响因素绘制ROC曲线,曲线结果显示供者性别、种族、尿酸、C-反应蛋白的AUC值均>0.60,说明以上指标为预警单倍型造血干细胞移植后发生aGVHD提供价值。利用以上独立影响因素构建列线图预警模型,危险因素分值相加所得数值即为单倍型造血干细胞移植后发生aGVHD的概率,验证结果显示,校准曲线的C-index值为0.846,表明该列线图预测模型预测能效良好。结论采用单倍型造血干细胞移植后aGVHD的影响因素构建的列线图可预测该病的发生概率,应针对性别、种族、C-反应蛋白等进行针对性治疗及护理,以降低aGVHD发生风险。Objective To explore the early warning model of acute graft-versus-host disease(aGVHD)after haplotype hematopoietic stem cell transplantation in adult myelodysplastic syndrome(MDS).Methods The clinical data of 50 adult MDS patients who received haplotype hematopoietic stem cell transplantation at the Second Affiliated Hospital of Air Force Medical University from January 2021 to January 2023 were included.Patients with acute graft-versus-host disease after treatment were included in the occurrence group,and patients without acute graft-versus-host disease were included in the non-occurrence group.The clinical data of patients were collected and analyzed,the influencing factors of acute graft-versus-host disease after haplotype hematopoietic stem cell transplantation were determined by Logistic regression analysis,and the nomogram early warning model was constructed by using the determined independent influencing factors,and the effectiveness of the nomogram prediction model for acute graft-versus-host disease after haplotype hematopoietic stem cell transplantation was evaluated.Results Fifty adult MDS patients received haplotype hematopoietic stem cell transplantation in our hospital.The incidence of patients with acute graft-versus-host disease was 30%,while the proportion of patients without acute graft-versus-host disease was 70%.Logistic regression analysis showed that donor sex,race and C-reactive protein were the risk factors for acute graft-versus-host disease(OR>1,P<0.05),while uric acid was the protective factor for acute graft-versus-host disease(OR<1,P<0.05)in adult MDS patients after haplotype hematopoietic stem cell transplantation.ROC curve was drawn with certain independent influencing factors,and the results showed that the AUC values of donor's sex,race,uric acid and C-reactive protein were all above 0.60,which indicated that the above indexes provided value for early warning of acute graft-versus-host disease after haplotype hematopoietic stem cell transplantation.Using the above independent inf
