研究设计:

Study design:

Sequential 

研究目的:

1.比较不同疗效(维奈克拉反应良好组 vs. 反应欠佳组)AML患者治疗前骨髓MDSC百分率、亚群比例及PD-L1表达率的差异。 2.动态观察AML患者治疗前后MDSC及其PD-L1表达水平的变化。 3.评估MDSC及其PD-L1表达率对维奈克拉化疗敏感性的预测效能(通过ROC曲线)。 4.分析MDSC及其PD-L1表达率在不同危险分层(低、中、高危)及是否中枢受累的AML患者中的差异。 5.探讨治疗前MDSC及其PD-L1表达率与临床指标(LDH、髓外浸润、原始细胞比例、染色体异常、血常规、性别、年龄等)的相关性。  

Objectives of Study:

1. Compare the differences in the percentage of bone marrow MDSCs, subpopulation proportions, and PD-L1 expression levels between AML patients with good response to Venetoclax and those with poor response before treatment. 2. Dynamically observe the changes in MDSCs and their PD-L1 expression levels in AML patients before and after treatment. 3. Evaluate the predictive performance of MDSCs and their PD-L1 expression levels for Venetoclax chemotherapy sensitivity (using ROC curves). 4. Analyze the differences in MDSC and its PD-L1 expression levels in AML patients with different risk stratifications (low, medium, high) and whether there is central involvement. 5. Explore the correlation between pre-treatment MDSC and its PD-L1 expression levels and clinical indicators (LDH, extramedullary infiltration, proportion of blast cells, chromosomal abnormalities, blood routine, gender, age, etc.).
