Gauging Incentive Values and Expectations (G.I.V.E.) among Blood Donors for Nonmonetary Incentives: Developing a Preference Elicitation Instrument through Qualitative Approaches in Shandong, China.

Introduction: Blood donation rates remain suboptimal in China necessitating the reform of the current nonmonetary incentive system to motivate donors. This study aims to identify relevant attributes and levels for nonmonetary incentives in repeated blood donation and provide insights for the development of preference elicitation instruments.

Methods: A qualitative research process was employed, including a literature review, in-depth interviews, attribute ranking, focus group discussions, and cognitive interviews, to identify potential nonmonetary incentives for blood donation.

Blood Donors' Preferences Toward Incentives for Donation in China.

Importance: Blood donation is critical for health care systems, but donor retention remains challenging. Understanding donors' preferences can inform incentive design and improve retention rates.

Objective: To identify donor preferences for incentive attributes and their relative importance in promoting blood donation among Chinese donors in Shandong.

[Analysis on Polymorphism of Platelet Antigen Gene in Shandong Han Population].

Objective: To study the Polymorphism of the human platelet antigen(HPA) gene 1-17 and human leukocyte antigen(HLA) gene-A and B locus in Shandong Han population.

Methods: A total of 962 samples from routine voluntary platelet donors were genotyped for HPA1-17 system and HLA-A site, B by PCR-SSP and PCR-SSOP respectively．Gene frequencies were calculated by counting. HPA1-17 and HLA genotype combinations were analyzed by Arelequin 3.

[Identification of a novel HLA allele A*29:49 using sequence based typing].

Objective: To report on a novel HLA-A allele, A*29:49, identified in a Chinese Han population by sequence based typing (SBT).

Methods: A donor from China Marrow Donor Programme (CMDP) was typed with a bi-allelic PCR-SBT kit, and no full matched result was obtained for the HLA-A locus. The novel HLA allele was verified with an allele-specific amplification SBT kit.

[Identification of a novel HLA allele, HLA-B*35:03:07, by sequencing-based typing].

This study was purposed to analyze and identify a novel HLA allele in Chinese population. A new HLA-B allele which is closely related to HLA-B*35:03:01 was initially detected by PCR-SSOP, then DNA sequencing was performed to identify the difference between the novel allele and HLA-B*35:03:01 allele. The result showed that the sequence of the new allele was different from all other known sequence.
