Patients with malignant tumors face an elevated risk of cerebrovascular complications, such as intratumoral hemorrhage, tumor invasion into arterial and venous sinuses, leptomeningeal infiltration, and tumor embolism. This review examines the significant role and implications of cisplatin and radiation therapy in the development of these cerebrovascular complications, which can occur at various stages: before, during, or long after the completion of cancer treatment. Detailed clinical case studies of CNS involvement during oncological therapy are presented to illustrate these complications. The mechanisms by which cisplatin and radiation therapy contribute to cerebrovascular disorders are multifaceted. Cisplatin, a widely used chemotherapeutic agent, is associated with endothelial damage and thromboembolic events, while radiation therapy can cause vascular injury, leading to long-term changes in cerebral vasculature. These treatments, though effective in managing malignancies, pose significant risks to cerebrovascular health. The review underscores the diverse types and mechanisms of stroke encountered in cancer patients, influenced by tumor stage and pathological characteristics. These include ischemic stroke, hemorrhagic stroke, and transient ischemic attacks, each requiring specific diagnostic and therapeutic strategies. The interaction between cancer pathology and cerebrovascular health necessitates a multidisciplinary approach, integrating oncology, neurology, radiology, and vascular surgery. Such an approach is crucial for effective management and prognosis evaluation in this patient population. Early recognition and intervention are paramount to mitigating risks and improving outcomes. By understanding these complex interactions, healthcare providers can better anticipate and manage cerebrovascular risks in patients undergoing cancer treatment. This comprehensive understanding helps in formulating personalized treatment plans, optimizing both oncological and neurological care, and ultimately enhancing patient quality of life and survival rates.

The integration of bioinformatics analysis into intracerebral hemorrhage (ICH)research represents a paradigm shift in our approach to understanding, diagnosing, and treating this complex neurological disorder. By leveraging the power of bioinformatics, the scientific community is poised to make significant strides in combating this devastating condition, ultimately improving patient outcomes and quality of life. This study provides a comprehensive overview of the application of bioinformatics tools and techniques in elucidating the genetic, molecular, and environmental underpinnings of ICH. Through a detailed examination of genomic sequencing, transcriptomics, proteomics, and machine learning, we explore how these bioinformatics approaches have contributed to identifying genetic variants, understanding molecular pathways, and discovering biomarkers related to ICH. Challenges such as data complexity, integration of multi-omics data, and the translation of bioinformatics findings into clinical practice are discussed, alongside ethical considerations surrounding data privacy and patient consent. This study underscores the critical role of bioinformatics in advancing our understanding of ICH, offering insights into its pathophysiology, and paving the way for personalized medicine and targeted therapeutic interventions.

Stroke, characterized by sudden onset and significant mortality rates, represents a critical challenge in effectively treating neuroinflammation to improve treatment efficacy. In this context, mesenchymal stem cell (MSC)-derived exosomes have attracted significant attention in scientific research due to their diverse cellular origin, tiny size, and huge number of bioactive molecules. Recent studies have shed light on the remarkable potential of MSC-derived exosomes to not only suppress the inflammatory responses of microglia and astrocytes, but also enhance their neuroprotective functions. Moreover, these exosomes have demonstrated a remarkable ability to modulate various immune cells and inflammatory mediators, thereby exerting profound mitigating effects on neuroinflammation. Through a thorough examination of the role and underlying mechanisms of MSC-derived exosomes in mitigating neuroinflammation after stroke, this review aims to provide comprehensive information and recommendations for the development of innovative therapeutic strategies aimed at significantly improving the treatment of stroke.
