目的 分析银川地区单采献血者流失原因,制定回召策略。方法 对银川地区末次献血时间在2019年1月1日—2020年12月31日的1 498名单采献血者逐个致电回访,使用SPSS 26.0软件进行统计学分析,不同组间变量比较用χ²检验,P<0.05为差异有统计学意义。结果 成功召回355人(23.7%),和未召回组比较,性别无统计学差异(P>0.05),各年龄段、民族、职业、文化程度、血型之间均有统计学差异(P<0.05)。18～24岁、汉族、国家企事业单位、研究生及以上学历人群回召率最高;随着年龄增长、文化程度降低,回召成功率下降。未召回原因中工作繁忙占比最大,其次为在外地、身体原因、亲友献血者、失联、学生毕业、对献血误解、停车不便。结论 不断优化、细化单采献血服务,让工作更加人性化,加大献血正面形象的宣传,不断创新,从而保留固定献血者。

Objective To analyze the causes of apheresis blood donors loss in Yinchuan area, and to work out the call-back strategy. Methods A total of 1 498 blood donors whose last blood donation time was between January 1, 2019 and December 31, 2020 in Yinchuan area were called one by one. SPSS 26.0 software was used for statistical analysis. Variables between different groups were compared usingχ² test, and P<0.05 was considered statistically significant. Results Three hundred and fifty-five people (23.7%) were successfully called back. Compared with the failed call-back group, there was no significant difference in gender (P>0.05), but there were significant differences in age, nationality, occupation, education level and blood type (P<0.05). People aged 18-24, with Han Nationality, working in national enterprises or institutions, or with graduate degree or above had the highest call-back rate; with the increase of age and the decrease of education level, the success rate of call-back decreased. Among the reasons for call-back failure, no free time accounted for the largest proportion, followed by being in other places, physical reasons, donors of relatives and friends, losing contact, graduated from school, misunderstanding of blood donation, and inconvenient parking. Conclusion We will continue to optimize and refine the apheresis blood donation service, make the work more humanized, expand the publicity of the positive image of blood donation, and innovate constantly, so as to retain the blood donors.

目的 了解广州市区全血乳糜血报废的趋势变化和献血人群特征,并分析其背后的原因,为进一步减少全血乳糜血报废提供参考依据。方法 通过广州血液中心信息系统检索,统计2017—2019年期间中心全血乳糜血报废量、报废率等相关数据,并分层统计性别、年龄、献血方式与报废的关系,提出有效减少乳糜血报废的对策。结果 2017—2019年期间广州血液中心共采集制备3 003 998单位血液,因乳糜血原因报废的血液达69 311单位,报废率2.31%,占总报废的44.02%。其中,男性献血者乳糜血报废率显著高于女性献血者,报废血液主要为18～40岁年龄段的无偿献血,约一半报废血来自团体献血者。结论 加大献血知识的宣传,特别是团体献血者;做细献血前征询工作和献血后跟踪随访;关注男性和年轻献血者,进一步减少全血乳糜血报废几率。

Objective To evaluate the trend of scrapped chylemia blood in whole blood collection and the characteristics of blood donors in urban area of Guangzhou, analyze the reasons behind so as to provide reference for further reducing chylemia blood scrapped. Methods Search the whole blood collection and scrapped chylemia blood data from 2017 to 2019 through the information system of Guangzhou Blood Center, stratifiy gender,age,donation way, and look for solutions. Results 3 003 998 U blood component were collected and prepared from 2017 to 2019. Totally 69 311 U chylemia blood were scrapped due to chylemia blood, accounting for 44.02% of the total discarded blood. Scrapped chylemia blood rate were significantly higher among male blood donors than among female donors,and mainly aged from 18-40 donors. About half of the discarded blood came from group donors. Conclusion Greater efforts to publicize especially for group donors,careful consultation before blood donation and follow-up after blood donation should be taken. We should pay close attention to male and young blood donors, so as to further reduce the possibility of scrapped chylemia blood.

目的 分析献血者乙型肝炎病毒(HBV)核酸检测非重复反应性确认及追踪结果。方法 对1 200例于我站无偿献血者的血液样本进行非重复反应性确认,补充乙肝“两对半”检测,并对其部分单项核酸检测反应的患者予以回访结果追踪。结果 1 200份无偿献血血液样本单项核酸检测有反应性者150份(12.50%)。150份单项核酸检测有反应性样本经重新病毒核酸检测后,仍有58例样本有反应性(38.67%)、92例样本为非反应性(61.33%)。其中有18例献血者实际召回抽血,完成两次追踪,第一次追踪60~125天,第二次追踪间隔天数在160~356天,第一次追踪HBV DNA有反应(+)8例,第二次追踪仍存在反应(+);7例HBV DNA有反应者存在抗-HBc阳性(+)。核酸反应检测HBV-DNA阳性值10~17有37.25%,高于核酸反应检测值<10的4.17%(P<0.05)。结论 部分单项核酸检测反应无偿献血者存在一定的输血传播HBV风险,多为HBV隐匿性感染,此时需要重视其输血情况,屏蔽单项核酸反应性献血者。

Objective To analyze the results of nonrepetitive reactivity of HBV nucleic acid detection in blood donors. Methods 1 200 blood samples from our station were confirmed by nonrepetitive reaction, supplemented with the “two to half” test of hepatitis B, and some patients with single nucleic acid detection were followed up. Results One hundred and fifty samples (12.50%) were reactive in single nucleic acid detection in 1 200 blood samples. After the virus nucleic acid detection, 58 samples were reactive (38.67%), 92 were nonreactive (61.33%). 18 donors were actually recalled and drew blood, completed two tracking. The first tracking time was 60-125 days, the second time interval was 160-356 days. In the first tracking 8 cases had HBV DNA reaction (+) , which still had reaction in the second tracking; 7 HBV DNA positive donors had HBC antibody (+).The proportion of HBV-DNA positive with 10-17 value in mucleic acid reaction test(37.25%) was higher than that with value below 10(4.17%,P＜0.05). Conclusion Some donors with single nucleic acid detection reaction have a certain risk of transmission of HBV, most of them had hidden infection of HBV. At this time, we should pay attention to the blood transfusion and avoid the single nucleic acid reactive donors.

目的 了解河源市无偿献血人群中丙型肝炎病毒(HCV)感染情况及HCV感染合并乙型肝炎病毒(HBV)、人类免疫缺陷病毒(HIV)以及梅毒螺旋体(TP)感染的情况,为当地预防和控制输血传播性疾病提供实验室依据。方法 选择2010年1月1日—2015年12月31日河源市中心血站无偿献血者71 618例,采用酶联免疫吸附试验(ELISA)方法检测其血浆抗-HCV、乙型肝炎表面抗原(HBsAg)、抗-TP及HIV(Ag/Ab),统计分析抗HCV阳性无偿献血者合并感染HBV、HIV和TP的情况。结果 71 618例无偿献血者标本中抗-HCV、HBsAg 、抗-TP及HIV(Ag/Ab) 阳性率分别为0.56％(402例)、1.48％(1 062例)、1.14％(821例)、0.09％(61例);初次献血者抗-HCV、HBsAg 、抗-TP及HIV(Ag/Ab)阳性率均高于多次献血者(P＜0.05);402例抗-HCV阳性无偿献血者中合并HBsAg、抗-TP、HIV(Ag/Ab) 阳性率分别为1.74%(7例)、4.98%(20例)、0.25%(1例)。结论 抗-HCV阳性献血者合并TP感染率显著高于抗-HCV阴性无偿献血者, HCV合并HBV、HIV感染率低。

目的 了解惠州地区无偿献血者中抗-Mur及Mur抗原的频率,为指导临床输血及建立稀有血型红细胞库提供依据。方法 用微板盐水法和凝聚胺法筛查8686名自愿无偿献血者血浆中的抗-Mur,再用微柱凝胶卡方法进一步确认;采用人源抗-Mur血清检测1119名献血者Mur抗原的红细胞表型。结果 无偿献血者血清中抗-Mur频率为0.35%(31/8686),男女间的差异有统计意义(P<0.05),女性高于男性;Mur抗原阳性频率为5.61％(63／1119)。结论 惠州地区无偿献血者中抗-Mur频率较高,而Mur抗原阳性则相对较常见,在输血前检查项目中增加Mur血型抗原抗体检测是非常必要的。

Objective To investigate the frequency of anti-Mur and Mur antigen among blood donors in Huizhou city and provide data for guiding clinical transfusion and establishing red blood cells library of rare blood type. Method Micro-plate brine method and polybrene method are used to screen anti-Mur from 8686 blood donors. DG Gel Coombs cards are used to confirm the result. Human anti-Mur serum is used to screen the phenotypes from other 1119 blood donors. Results The frequency of anti-Mur was 0.35%(31/8686). The differences between men and women had statistical significance (P<0.05), of which women were higher than men. The frequency of Mur antigen positive was 5.61％(63／1119). Conclusion The blood donors in Huizhou showed a high frequency of anti-Mur and a relatively high frequency of Mur antigen, so it is very necessary to add test method of Mur blood group antigen and antibody before the donors carry out the blood transfusion process.
