目的 探讨特发性间质性肺炎（IIPs）[非特发性肺间质性纤维化（IPF）型]合并弥漫性肺部出血综合征患者治疗方案以及应用价值。方法 报道1例IIPs（非IPF型）合并弥漫性肺部出血综合征患者的治疗经过以及结果,结合文献分析治疗IIPs（非IPF型）合并弥漫性肺部出血综合症临床应用价值。结果 该文报道 l 例特发性肺间质肺炎（非IPF型）伴弥漫性肺泡出血综合征的老年男性患者,合并呼吸、循环衰竭,启用静脉-静脉体外膜肺氧合（VV-ECMO）抢救并成功撤机,病情好转出院。结论 IIPs作为病因以及发病机制未明、临床表现多样的一类肺间质性疾病,需临床多学科协作,及早诊断、治疗,才能成功挽救患者。

Objective To explore the treatment plan and application value of idiopathic interstitial pneumonia（non IPF）complicated with diffuse alveolar hemorrhage syndrome．Methods A case of idiopathic interstitial pneumonia（non IPF）complicated with diffuse alveolar hemorrhage syndrome was reported．The clinical application value of treatment of idiopathic interstitial pneumonia（non IPF）complicated with diffuse alveolar hemorrhage syndrome was analyzed combined with the literature．Results A case of idiopathic interstitial pneumonia（non IPF type）with diffuse alveolar hemorrhage syndrome was reported in this paper． Combined with respiratory and circulatory failure,veno-venous extracorporeal membrane oxygenation was used to rescue and successfully wean,and the condition improved and discharged．Conclusions Through the curative effect evaluation of this patient,it is believed that idiopathic interstitial pneumonia,as a kind of pulmonary interstitial disease with unknown etiology and pathogenesis and diverse clinical manifestations,need clinical multidisciplinary cooperation,early diagnosis and treatment,in order to successfully save the patient．

目的 研究未成熟血小板分数(IPF)、高荧光未成熟血小板比例(H-IPF)指标在血流感染中的早期诊断价值。方法 选取2020年7月—2021年1月广州市第一人民医院的血培养阳性患者100例作为主要的研究对象,重症病人对照50例,健康对照50例。收集各组患者IPF、H-IPF、大型血小板比率(P-LCR)、血小板体积分布宽度(PDW)、粒/淋、粒/单指标的数值,采用单因素方差分析、构建ROC曲线的方法分析比较各组的IPF、H-IPF、P-LCR、PDW、粒/淋、粒/单比值的差异及其与血流感染效能的关系。结果 IPF、H-IPF、粒/淋、粒/单比值在血流感染组高于其他2组,差异有统计学意义(χ²分别是15.190,10.250,39.490,12.850;P<0.05),而 P-LCR、PDW在3组之间无统计学意义。其中,IPF与H-IPF对血流感染诊断效能较高,其中IPF的AUC为0.855(95% CI为0.737～0.973),H-IPF的AUC为0.845(95% CI为0.722～0.968)。结论 IPF、H-IPF与血流感染密切相关,这2个指标对血流感染患者具有一定的诊断价值。

Objective To explore the early diagnosis value of immature platelet fraction (IPF) and high fluorescent immature platelet fraction (H-IPF) in bloodstream infection.Methods A total of 100 patients with positive blood culture result from July 2020 to January 2021 in Guangzhou First People's Hospital were selected as the research objects,in the mean while,50 critically ill patients and 50 healthy patients were enrolled as two control groups.The values of IPF,H-IPF,platelet-large cell rate (P-LCR),platelet distribution width (PDW),neutrophils/lymphocytes,neutrophils/monocyte ratio of patients in each group were collected,and one-way analysis of variance and ROC curve were used to compare the data,to further analyze their relationship with the bloodstream infection.Results The IPF,H-IPF,neutrophils/lymphocytes,neutrophils/monocyte ratio in the bloodstream infection group were significantly higher than control groups,with statistical significance (χ²=15.190,10.250,39.490,12.850; P<0.05),while P-LCR and PDW had no statistical significance.Among them,IPF and H-IPF were highly effective in diagnosing bloodstream infection,the AUC of IPF was 0.855 (95% CI: 0.737-0.973) and the AUC of H-IPF was 0.845 (95% CI: 0.722-0.968).Conclusions IPF and H-IPF were closely related to bloodstream infection,and these two indicators had a certain value in diagnosing patients with bloodstream infection.
