目的 探讨河源地区机采血小板固定献血者血小板抗原系统的基因多态性特征,为建立本地区机采血小板供血者库奠定基础。方法 采用PCR-SSP方法对100例机采血小板固定献血者进行血小板抗原HPA1～17系统基因分型。结果 HPA1～17基因中成多态性分布的等位基因是HPA2a、HPA3a、HPA5a、HPA15a,其频率分别为0.96、0.49、0.99、0.515。HPA-2、HPA-3、HPA-5、HPA-15系统存在aa、ab、bb 三种表型。HPA1a、HPA4a、HPA6a-14a、HPA16a-17a基因频率为1,呈单线性分布,未发现b基因。结论 河源地区血小板HPA-3系统不配合率最高(0.420),HPA-15系统次之。建立本地区机采血小板供血者库,为患者提供HPA相合的血小板,对减少临床血小板输注无效的发生具有重要意义。

Methods PCR-SSP method was used to analyze HPA 1～17 genotype in 100 fixed platelet donors. Results The highest numbers of heterozygotes were HPA2a,HPA3a,HPA5a and HPA15a,with frequencies of 0.96,0.49,0.99 and 0.515,respectively. The frequencies of HPA1a,HPA4a,HPA6a-14a and HPA16a-17a genes were 1,which showed a single linear distribution. Conclusion HPA-3 system were the highest mismatch rate (0.420),followed by HPA-15 system. It is great significance to establish a local platelet donor bank and provide HPA compatible platelets for patients.

目的 探索连续捐献机采血小板献血者血小板、白细胞和红细胞计数变化情况。方法 以2016年1月1日—2018年9月30日年期间首次献血且连续血小板捐献量在10 U及以上的849人为研究对象进行回顾性研究,采用同一群体的配对t检验来评估第一次与最后一次血小板、红细胞及白细胞计数的变化情况。将采用有序多分类Logistic回归分析调查期间的血小板捐献量对献血者外周血细胞计数的影响。结果 配对t检验表明,外周血PLt有增加趋势(t=-8.58,P<0.001);白细胞总体来说有减少趋势(t=5.348,P<0.001);红细胞无改变趋势(t=0.515,P=0.607);有序多分类Logistic回归分析结果显示:PLt的变化值与献血者年龄、性别以及第一次与最后一次献血的间隔期无关系,P＞0.05;但是与血小板捐献量41 U及以上比起来,血小板捐献量在≤30 U的献血者,血小板计数增加的可能性相对较少(血小板捐献量为10～20 U,χ²=13.737,P<0.001;血小板捐献量为21～30 U,χ²=7.491,P=0.006);WBC的变化值与献血者年龄、性别及献血间隔期无关,P＞0.05,但是与血小板捐献量41 U及以上比起来,血小板捐献量在10～20 U的献血者,白细胞计数增加的可能性相对较大,(OR=1.720,95%CI=1.136~2.605,P=0.010) RBC的变化值与献血者年龄、性别无关(P＞0.05);第一次与最后一次献血间隔期越长,红细胞计数增加的可能性就越大,(OR=1.005,95%CI=1.000~1.009,P=0.030);但是与血小板捐献量并无关系。结论 血小板捐献间隔期不少于2周间隔期的连续血小板献血者,其外周血PLt和RBC在一定时间内变化情况会受到血小板捐献量的影响而发生增加和减少的变化,但均在正常范围内波动。

Objective To explore the changes of platelet, white blood cell and red blood cell counts of long-term platelet blood donors. Methods A retrospective study was conducted on 849 platelet blood donors who donated for the first time and continuously donated amounts to 10U plateletor or more from January 1, 2016 to September 30, 2018.The paired t test of the same group was used to evaluate the changes of platelet, red blood cell and white blood cell counts between the first time and the last time donation during the study period. Ordinal multinomial logistic regression was conducted to analyze the effects of platelet donation on the peripheral blood cell count of the donor during the survey. Results Paired t-test result showed that there was a increase in PLt (t=-8.58, P<0.000 1);a decrease in WBC(t=5.348, P<0.000 1); and no significant change in RBC (t=0.515, P=0.607).The results of ordinal multinomial logistic regression analysis showed that the change in PLt had no relationship with age, sex, and interval between the first and last blood donation, P>0.05. Compared with donors who donated 41U or above,the possibility of an increase in platelet count was relatively small for those who donated 30U or below(platelet donation amount 10~20U,χ²=13.737,P<0.000 1;platelet donation amount 21～30U,χ²=7.491,P=0.006). There was no relationship between age, gender, and blood donation interval and WBC changes, P>0.05. Compared with donors who donated 41U or above, WBC was more likely to increase for those who donated 10～20 U (OR=1.720, 95%CI=1.136~2.605, P=0.010).RBC changes had nothing to do with age, gender and platelet donation amount of the blood donor, P> 0.05; the longer the interval between the first and last blood donation took, the more likely the red blood cell count increased, (OR=1.005, 95%CI=1.000~1.009, P=0.030). Conclusion For continuous platelet donors with platelet donation intervals of no less than 2 weeks, platelet donation amount will affect the peripheral blood counts,and all the blood conuts are within the normal range.

目的 探讨利用微信群保留机采血小板无偿献血者的应用效果。方法 从本血站穿越安全输血标准化管理系统中调取2015年1月1日—2018年12月31日捐献机采血小板无偿献血者信息,根据初次捐献机采血小板后是否自愿加入机采微信群的机采血小板无偿献血者分为实验组和对照组,统计分析各组机采血小板无偿献血者重复献血 2～3 次和≥4 次以上机采血小板无偿献血者人数及平均献血次数。结果 2015—2018年间机采血小板采集量、献血人数及平均献血次数逐年上升;重复献血 2～3 次和≥4 次以上人数,实验组均高于对照组,机采血小板平均献血次数实验组均高于对照组,其中2016年和2018年实验组机采血小板平均献血次数高于对照组(P<0.05)。结论 通过机采微信群预约与管理机采血小板无偿献血者可提高机采血小板招募的工作效率,有效扩大和稳定机采血小板无偿献血者固定队伍。

目的 探讨影响初次机采血小板献血者再次捐献的相关因素,为制定机采献血者保留策略提供依据。方法 选择2016年1月1日—2016年12月31日在广州血液中心首次成功捐献机采血小板的13 899例献血者为研究对象,分析每个献血者献血时性别、年龄、文化程度、是否发生献血不良反应与下一年度是否再次捐献机采血小板的相关性。结果 男性献血者再次捐献率(10.68%)高于女性献血者再次捐献率(8.94%),差异有统计学意义(P＜0.01);献血者年龄18～25岁组再次捐献率最高为12.86%,46～60岁组再次捐献率最低为6.46%,差异有统计学意义(P＜0.001);献血者文化程度高中或职中组再次捐献率最高为11.23%,本科或以上组再次捐献率最低为8.94%,差异有统计学意义(P＜0.001);未发生不良反应献血者再次捐献率(10.37%)高于发生不良反应献血者再次捐献率(5.56%),差异有统计学意义(P＜0.01)。结论 男性、年龄较小、文化程度较低和未发生献血不良反应的献血者更愿意返回再次捐献机采血小板,对这部分献血者采取针对性保留措施,有利于建立起一支固定捐献机采血小板的献血者队伍。

Objective To explore the related factors affecting the re-donation of the first apheresis platelet donors, and to provide a basis for the retention strategy. Methods A total of 13 899 blood donors who successfully donated apheresis platelets for the first time in Guangzhou Blood Center from January 1, 2016 to December 31, 2016 were selected as subjects. The correlation among gender, age, education level, adverse reactions of blood donation and whether platelet collection was re-donated in the next year was analyzed. Results Re-donation rate of male blood donors (10.68%) was higher than that of female blood donors (8.94%). The difference was statistically significant (P<0.01). Re-donation rate of blood donors aged 18～25 was the highest 12.86%, and that of 46～60 was the lowest 6.46%. The difference was significant (P<0.001). Re-donation rate of high school or vocational college blood donors was the highest 11.23%. The lowest re-donation rate was 8.94% in the undergraduate group or above, and the difference was statistically significant (P< 0.001). The re-donation rate of donors without adverse reactions (10.37%) was higher than that of donors with adverse reactions (5.56%). The difference was statistically significant (P<0.01). Conclusion Male, younger, less educated and no adverse reactions to blood donation are more willing to return to donate platelet again. Targeting these donors for reserve measure will conducive to the establishment of a fixed platelet donor team.

目的 探讨机采血小板献血者流失原因,为建立一支稳固的机采血小板献血者队伍提供参考。方法 选择2009年1月1日—2012年12月31日河源市中心血站首次机采血小板献血者共382例为研究对象,根据其首次机采血小板献血后3年内是否再次参加机采血小板献血分为实验组和对照组,分别对研究对象进行电话回访调查。结果 3年内未再次参加血小板献血流失者118例,总流失率为30.89%;不同献血动机组流失率差异有统计学意义 (χ²= 18.552,P=0.000),其中动机不明确组流失率(52.49%)最高,寻求社会荣誉组流失率(15.79%)最低。发生过献血反应组(63.64%)流失率显著高于未发生献血反应组流失率(26.63%),两组间差异有统计学意义(χ²=8.501,P=0.004);对献血过程不满意组流失率(39.77%)显著高于满意组流失率(28.23%),两组间差异有统计学意义(χ²=16.413,P=0.000);认为机采时间过长组机采血小板献血者流失率(49.40%)显著高于不认为机采时间过长组流失率为(25.75%),两组间差异有统计学意义(χ²=17.014,P=0.000)。健康状况(体检结果)不合格组流失率(43.84%)显著高于合格组流失率(27.83%),两组间差异有统计学意义(χ²=9.022,P=0.030)。媒体(或网络)负面的宣传与献血者是否方便对机采血小板献血者流失率的影响不显著(χ²=1.579,P=0.209;χ²=2.130,P=0.144)。结论 机采血小板献血者流失主要与献血动机、献血过程感受以及自身健康等因素有关。

       目的   探讨口服铁剂方法用于改善铁缺乏的男性机采血小板固定献血者铁营养状况效果，为采供血机构完善无偿献血者关爱策略提供数据支持。方法   选择2022年9月—2023年8月珠海市中心血站男性血小板固定献血者进行铁蛋白（FER）检测。以FER＜30 ng/mL为铁缺乏的判定标准。将49名铁缺乏的男性机采血小板固定献血者随机分成干预组、对照组，分别进行口服铁剂干预，比较两组干预前后血红蛋白（Hb）、血清铁（SI）、FER的浓度变化情况。结果   共检测205名男性机采固定献血者，其中49名FER＜30 ng/mL（铁缺乏组），占23.90%，其Hb、SI、FER均值低于FER≥30 ng/mL男性机采固定献血者（正常组）。49名铁缺乏的机采固定献血者口服铁剂干预后：干预组SI、FER浓度分别为（15.97±5.14）μmol/L、（30.55±14.42）ng/mL，高于对照组［（11.49±4.02）μmol/L、（12.77±5.86）ng/mL）］，其差异有统计学意义（t=3.466，P＜0.001；t=5.493，P＜0.001）。干预组Hb为（143.42±10.85）g/L，高于对照组的（140.88±12.97）g/L，但差异无统计学意义（t=-0.726，P=0.471）。结论   针对铁蛋白低值的机采男性固定献血者，采取口服铁剂方法可以有效改善其铁缺乏状况。
