目的 探讨自发性脑出血（SICH）患者静脉血栓栓塞症（VTE）的独立危险因素,并评估针对性分层预防措施的有效性及安全性, 为临床优化防治策略提供依据。方法 回顾性纳入2022年1月—2025年1月收治的86例SICH患者, 根据下肢深静脉超声结果分为深静脉血栓（DVT）组（n=16）与非DVT组（n=70）。采集患者基线资料、临床特征及实验室指标, 采用单因素及多因素Logistic回归分析VTE危险因素, 并基于独立危险因素制定分层预防方案。结果 多因素分析显示, 体质指数（BMI）升高（OR=1.22, 95%CI：1.06~1.41）、中心静脉置管（OR=5.23, 95%CI：1.37~19.95）、止血药物使用（OR=4.80, 95%CI：1.21~19.01）及NIHSS评分升高（OR=1.20, 95%CI：1.02~1.42）是VTE的独立危险因素（均P<0.05）。因此需针对SICH患者进行针对性干预, 包括基于BMI的个体化干预、中心静脉置管的精细化管控、止血药物的动态调控及神经功能保护与早期康复。结论 SICH患者VTE发生与代谢、医源性及神经功能损伤多因素交互作用密切相关, 应针对患者构建基于BMI、中心静脉管理及凝血监测的分层预防策略。

       Objective To explore the independent risk factors for venous thromboembolism（VTE）in patients with spontaneous intracerebral hemorrhage（SICH）and to assess the effectiveness and safety of targeted stratified prophylaxis to provide a basis for optimizing prevention and treatment strategies in the clinic．Methods A retrospective analysis was conducted on 86 SICH patients admitted between January 2022 and January 2025．Based on lower-extremity venous ultrasound findings, patients were divided into a deep venous thrombosis（DVT）group（n=16）and a non-DVT group（n=70）．Baseline characteristics, clinical features, and laboratory indicators were collected．Univariate and multivariate Logistic regression analyses were performed to identify VTE risk factors, and a stratified prevention protocol was developed based on independent risk factors．Results Multivariate analysis revealed that elevated body mass index（BMI）（OR=1.22, 95%CI：1.06-1.41）, central venous catheterization（OR=5.23, 95%CI：1.37-19.95）, hemostatic drug use（OR=4.80, 95%CI：1.21-19.01）, and higher NIHSS scores（OR=1.20, 95%CI：1.02-1.42）were independent risk factors for VTE（all P<0.05）．Consequently, targeted nursing interventions should be implemented for SICH patients, including BMI-based personalized care, refined management of central venous catheters, dynamic regulation of hemostatic drugs, and neuroprotective early rehabilitation．Conclusions VTE in SICH patients is closely associated with the interplay of metabolic, iatrogenic,and neurological injury factors．A stratified prevention strategy incorporating BMI monitoring, central venous catheter management, and coagulation surveillance is critical for reducing thrombotic risk while ensuring safety．

自发性脑出血（SICH）是脑卒中的一种常见形式,其预后通常较差,因此早期评估和调节患者出血后的免疫状态至关重要。免疫检查点是评估T淋巴细胞活跃性和增殖状态的关键指标,监测这些检查点有助于预测脑出血患者的预后。程序性死亡蛋白1（PD-1）和细胞分化抗原28（CD28）作为两个典型的免疫检查点,它们在脑出血预后评估中的应用正逐渐成为研究的热点。该文综述了脑出血后机体免疫状态的变化,以及PD-1和CD28在脑出血后评估和治疗中的研究进展。

Spontaneous intracerebral hemorrhage（SICH）is a common cause of stroke,with specific outcomes often being poor．Therefore,early assessment and modulation of the immune status after hemorrhage are of critical importance．Immune checkpoints serve as key indicators for assessing the activation and proliferation of T cells,and monitoring these checkpoints can help to predict the outcomes of patients with intracerebral hemorrhage．PD-1（programmed death 1）and CD28（Cluster of Differentiation 28）are two representative immune checkpoints,and their use in prognostic assessment after intracerebral hemorrhage is becoming a focus of research．This article reviews the changes in the immune state of the body after intracerebral hemorrhage,as well as the research progress on the use of PD-1 and CD28 in the evaluation and treatment following intracerebral hemorrhage．
