Objective: To report on three patients with paraquat (PQ) intoxication surviving after combined therapy with hemoperfusion (HP), cyclophosphamide (CTX), and glucocorticoid. Methods: Three patients suffered acute renal failure in a few days after ingesting a lethal amount of PQ. Chest computed tomography (CT) scans revealed obvious pulmonary inflammation, pleural effusion, and fibrous lesions several days after ingestion. HP was performed immediately, followed by large doses of glucocorticoid (methylprednisolone, 500 g/d) and CTX (approximately 4 g). Results: After 50 d of treatments, all three patients were discharged in healthy condition, with chest CT showing small fibrous lesions, exuda- tion, and both lungs clear of auscultation. Conclusions: The protective effect of the lungs may have been due to timely treatment at adequate doses.

目的:研究正常人与脓毒症患者血清差异表达蛋白中C-型凝集素域家族3成员B(CLEC3B)蛋白,探讨目标CLEC3B蛋白作为脓毒症分子标志物的可能性。方法:收集10名健康志愿者(健康组)和18例脓毒症患者(脓毒症组)外周血,利用数据独立采集法对外周血清蛋白数据进行采集,数据上传至i dep在线平台分析脓毒症患者外周血中差异表达蛋白。并对这些差异蛋白进行生物信息学分析,筛选出脓毒症关键蛋白。酶联免疫吸附法(ELiSA)验证并绘制关键蛋白受试者工作特征(ROC)曲线。结果:蛋白质组学分析筛选出138个差异表达蛋白(deps),其中34个蛋白显著下调,104个蛋白显著上调。deps主要富集在细胞过程、生物调节、生物过程调节、参与绑定、催化活化、分子功能监管、免疫系统、信号转导等。deps构建蛋白-蛋白相互作用网络(PPi)筛选出感兴趣的关键蛋白CLEC3B。ELiSA实验表明脓毒症组患者CLEC3B蛋白浓度(297.73±22.00)ng/ml显著低于健康组(452.42±191.72)ng/ml,差异具有统计学意义(t=13.13,P=0.000)。CLEC3B蛋白的ROC曲线下面积为0.998,灵敏度为97.73%,特异度为100.0%。结论:CLEC3B蛋白在脓毒症组中显著降低,其灵敏度高,特异度高,可以作为脓毒症潜在的生物学诊断标志物。临床试验注册号中国临床试验注册中心,ChiCTR1900021261。
