研究目的:

1. 主要目的:通过观察接受拟行下肢骨折手术患者术后认知功能发生情况与患者围术期IL-6 Trans-signaling活性的关键分子 IL-6/sIL-6R的表达情况和围术期血脑屏障通透性指标的NSE和S100β在外周血液的表达情况,评价围术期IL-6 Trans-signaling与PND之间是否存在相关性,寻找对老年患者术后认知功能有预测价值的生化标志物,提高高危患者PND风险的识别能力。 2. 次要目的:通过对临床病例寻找与PND发病相关的关键生化标志物,为后期的动物实验深入研究PND发病机制提供临床线索  

Objectives of Study:

To evaluate whether there is a correlation between IL-6 Trans-signalling and postoperative neurocognitive disorders, to carry out valuable biochemical markers for PND in elderly patients, and to improve the ability to identify PND risks in high-risk patients by observing of patients undergoing elective major lower limb fracture surgery, the expression of sIL-6R , NSE and S100β in blood.
