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.

肝细胞肝癌(HCC)是世界上最常见的肿瘤之一,其病因及确切的分子机制尚不完全清楚,目前认为其发病是多因素、多步骤的复杂过程,且预后较差。miRNAs在调控细胞的周期变化中起到重要的作用,它具有较高的组织特异性,在肿瘤发生中起到关键作用,从而有潜力作为肝癌的诊断和分类的新生物标志物,以及预测患者预后的工具。本文就近年来miRNAs在肝细胞肝癌方面的研究进展做一综述。
