疼痛作为肿瘤患者最常见的症状群,会给患者身心造成极大的痛苦,因此,疼痛治疗是综合治疗的重要组成部分。疼痛是指与组织损伤或潜在组织损伤相关联的、不愉快的感觉和情绪体验,其被认为是继心率、血压、脉搏、呼吸之外的第5大生命体征。疼痛不仅是困扰患者的症状,也是一种疾病。长期的疼痛刺激可导致中枢神经系统的病理性重构,引起疼痛的进展,从而形成难治性疼痛。早期识别、评估、规范化治疗疼痛,可以避免或延缓这一过程的发展。因此,重视肿瘤患者疼痛的全程管理,有助于改善患者的预后,提高生活质量。本文就肿瘤患者疼痛护理研究现状、疼痛门诊规范化诊疗体系建立、疼痛示范病房的建立、疼痛患者延续性护理、疼痛专科护士培训等进行简要综述。

Spinal cord injuries lead to significant loss of motor, sensory, and autonomic functions, presenting major challenges in neural regeneration. Achieving effective therapeutic concentrations at injury sites has been a slow process, partly due to the difficulty of delivering drugs effectively. Nanoparticles, with their targeted delivery capabilities, biocompatibility, and enhanced bioavailability over conventional drugs, are garnering attention for spinal cord injury treatment. This review explores the current mechanisms and shortcomings of existing treatments, highlighting the benefits and progress of nanoparticle-based approaches. We detail nanoparticle delivery methods for spinal cord injury, including local and intravenous injections, oral delivery, and biomaterial-assisted implantation, alongside strategies such as drug loading and surface modification. The discussion extends to how nanoparticles aid in reducing oxidative stress, dampening inflammation, fostering neural regeneration, and promoting angiogenesis. We summarize the use of various types of nanoparticles for treating spinal cord injuries, including metallic, polymeric, protein-based, inorganic non-metallic, and lipid nanoparticles. We also discuss the challenges faced, such as biosafety, effectiveness in humans, precise dosage control, standardization of production and characterization, immune responses, and targeted delivery in vivo. Additionally, we explore future directions, such as improving biosafety, standardizing manufacturing and characterization processes, and advancing human trials. Nanoparticles have shown considerable progress in targeted delivery and enhancing treatment efficacy for spinal cord injuries, presenting significant potential for clinical use and drug development.
