摘　　要：目的分析血细胞检查结果中红细胞直方图为双峰患者的血细胞特征及常见病因。方法回顾性分析2015年1月—2020年6月本院收治的红细胞直方图明显双峰且RDW无结果患者328例临床资料,根据红细胞直方图及仪器报警信息,对患者进行血细胞检测结果及病因分析。结果328例患者中有贫血患者207例(63.1%),以轻度(122/37.2%)、中度(68/20.7%)贫血为主,多为小细胞性贫血(117/35.7%)、正细胞性(60/18.3%)、大细胞性贫血(30/9.1%);红细胞直方图全部异常,均为双峰且RDW无结果。恶性肿瘤、慢性感染、缺铁性贫血、消化道出血、巨幼细胞贫血、子宫异常出血等是最常见的原发病因,输血和贫血治疗有效是红细胞直方图双峰最常见的治疗相关的原因。结论血常规检查红细胞双峰,RDW无结果患者常见的病因是营养性贫血、慢性病贫血等。外周血出现双相红细胞是红细胞检查的明显特征,见于急性失血和贫血药物治疗后,反映骨髓红系增生旺盛,贫血治疗有效和贫血、失血患者的临床输血治疗后。Objective To analyze the characteristics of blood cells in patients whose red blood cell histograms presents bimodal and its common etiology.Methods Retrospective analysis was carried out on 328 cases of patients admitted to our hospital from January 2015 to June 2020,whose red blood cell histograms presented obvious double peaks and no RDW results.According to the red blood cell histogram and the alarm information of the instrument,blood cell test results and etiology analysis were performed on the 328 patients.Results Among the 328 patients,207(63.1%)had anemia,mainly were mild(122/37.2%)and moderate anemia(68/20.7%).The type of anemia were mostly small cell anemia(117/35.7%),normal cell anemia(60/18.3%),and large cell anemia(30/9.1%).The histograms of red blood cells were all abnormal,presented bimodal peaks and without RDW results.The common causes were malignant tumor,chronic infection,iron deficiency anemia,gastrointestinal bleeding,macrocytic anemia,and abnormal uterine bleeding.The most common treatment-related causes are blood transfusion and anemia treatment.Conclusions The common etiologies of the patients without RDW results were chronic anemia and nutritional anemia,et al.The bipolar red blood cells in peripheral blood is the obvious characteristics of red blood cell examination,which can be seen after acute blood loss and anemia treatment,reflecting the exuberant proliferation of bone marrow,effective anemia treatment and clinical transfusion therapy in patients with anemia blood loss.
