很多人知道帕金森病会导致手抖、走路慢、身体僵硬。但一些患者家属会发现，病人夜里睡着后并不安宁：说梦话、大声喊叫、挥舞手臂、踢腿，有时甚至把同床的家人打醒，或者自己从床上摔下来。 这种现象在医学上叫做快速眼动睡眠行为障碍，简称RBD。它并不是单纯的睡相差，而是一种明确的睡眠疾病。大约40%到50%的帕金森病患者会伴有这种情况。更值得关注的是，伴有睡眠行为障碍的帕金森病患者，病情往往更重：运动问题更突

房室结（atrioventricular node，AVN）在心房和心室之间起着关键的电传导作用，确保心脏收缩的同步性。与周围的心肌相比，房室结传导电信号的速度较慢，从而形成了一段延迟时间，使心室能够在收缩前充分充盈。 此外，房室结还会阻断过快的心房节律（例如在心房颤动期间）的传导，防止可能导致危及生命的室性心律失常。在心脏的主要起搏器——窦房结（sinoatrial node，SAN）出现故障的

自然杀伤（NK）细胞在宿主对癌症的免疫监视过程中，是固有免疫系统发挥保护作用的关键因素。与适应性免疫系统中的细胞毒性淋巴细胞不同，NK 细胞具有独立于人类白细胞抗原（HLA）分子所呈现的特异性肿瘤抗原而识别并杀死转化细胞的内在能力，其激活机制由诸如白细胞介素（IL）-15 或 IL-12 等细胞因子以及一系列基因编码的激活受体所驱动。 NK 细胞还通过激活和招募常规型 1 树突状细胞（cDC1）来
