研究目的:

本研究通过观察恶性肿瘤小儿术中异体输血后相关蛋白及Tregs数量和功能的变化,初步分析异体输血影响恶性肿瘤患者免疫功能的具体机制,从而为减少输血相关免疫不良反应,提高肿瘤病人输血安全性提供新的思路与策略。  

Objectives of Study:

In this study, the number and function of related proteins and Tregs after allogeneic blood transfusion in children with intracranial tumor were observed, and the mechanism of allogeneic blood transfusion affecting the immune function of patients with malignant tumor was preliminarily analyzed, so as to provide new ideas and strategies for reducing the adverse reactions of transfusion related immune and improving the safety of blood transfusion of tumor patients.
