研究目的:

1. 有效白蛋白的临床应用评价 (1). 结合24周白蛋白水平、24周差异白蛋白水平和其他临床指标,使用单因素COX回归分析72周时失代偿期肝硬化再代偿的影响因素,明确有效白蛋白; (2). 将有效白蛋白水平与再代偿显著相关的因素纳入多因素COX回归分析,形成优化的乙肝失代偿期肝硬化患者再代偿预测模型;利用Youden指数,找到有效白蛋白水平预测肝硬化再代偿的最佳cut-off值;绘制Nomogram图展示模型列线图,通过RMS曲线、时间依赖性ROC分析、校准曲线和决策曲线分析(DCA)综合评价列线图预测性能;利用外部验证队列,评价预测模型的预测效果。 (3). 探索使用随机森林、支持向量机、神经网络等机器学习方法构建预测模型,通过AUROC曲线下面积评估该预测模型的预测效果。 2. 有效白蛋白诊断试剂盒和治疗产品的研发 (1). 利用单克隆或多克隆抗体技术,制备有效白蛋白的特异性抗体。之后基于有效白蛋白结构分析和临床检测试剂盒开发技术,开发针对有效白蛋白定量分析的ELISA试剂盒,初步评价试剂盒检测效能,包括灵敏度、特异度指标; (2). 基于蛋白真核细胞表达系统和亲和层析等蛋白纯化技术,探索有效白蛋白工业化表达、生产条件,并验证其蛋白结构,为后续进行合成白蛋白药物研发奠定基础。  

Objectives of Study:

1. Clinical Application Evaluation of Effective Albumin (1). Evaluate the influencing factors of recompensation in decompensated cirrhosis at 72 weeks by using univariate COX regression analysis, considering 24-week albumin levels, 24-week differential albumin levels, and other clinical indicators, to identify effective albumin. (2). Incorporate factors significantly related to recompensation, including effective albumin levels, into a multivariate COX regression analysis to develop an optimized prediction model for recompensation in patients with hepatitis B decompensated cirrhosis. The Youden index will be used to determine the optimal cut-off value of effective albumin levels for predicting recompensation. A nomogram will be created to display the model’s scoring system, and the prediction performance will be comprehensively evaluated using RMS curves, time-dependent ROC analysis, calibration curves, and decision curve analysis (DCA). The predictive performance of the model will be validated using an external validation cohort. (3). Explore the use of machine learning methods such as random forests, support vector machines, and neural networks to construct a prediction model, and assess its predictive performance through the area under the AUROC curve. 2. Development of Diagnostic Kits and Therapeutic Products for Effective Albumin (1). Utilize monoclonal or polyclonal antibody techniques to prepare specific antibodies against effective albumin. Based on structural analysis of effective albumin and clinical diagnostic kit development technologies, an ELISA kit for the quantitative analysis of effective albumin will be developed. The detection performance of the kit, including sensitivity and specificity indicators, will be preliminarily evaluated. (2). Explore the industrial-scale expression and production conditions of effective albumin using protein eukaryotic expression systems and affinity chromatography, and verify its protein structure to lay the foundation for subsequent development of synthetic albumin-based drugs.
