队列研究 

Study design:

Cohort study 

研究目的:

1.探讨口腔菌群失调与围手术期神经认知障碍之间的相关性。 2.验证口腔菌群是否直接通过血脑屏障诱导神经炎症导致围手术期神经认知障碍发生。  

Objectives of Study:

1.To explore the correlation between oral flora imbalance and perioperative neurocognitive impairment; 2. Verify whether the oral microbiota directly induces neuroinflammation through the blood-brain barrier, leading to the occurrence of perioperative neurocognitive impairment.

指标类型:

主要指标

Outcome:

Salivary microbiome (16S rRNA sequencing) analysis

Type:

Primary indicator

测量时间点:

术前1天、术后第3天

测量方法:

本实验采集的唾液样本均为非刺激性唾液,分别在术前1天及术后第3天采集患者唾液,采集前让患者漱口,之后将5ml无菌EP管置于患者下唇黏膜,指导受试者让唾液自然流入,采集量为1ml,不能咳痰,在2小时内将采集的唾液样本转运至-80℃冰箱中保存备用。 将采集的唾液进行16SrRNA测序后进行以下分析: α多样性:采用 Shannon 和 Chao1 指数评估; β多样性:采用主坐标分析(PCoA)评估;

Measure time point of outcome:

One day before the operation and the third day after the operation

Measure method:

Saliva was collected from the patients one day before the operation and on the third day after the operation. Before collection, the patients were asked to rinse their mouths. Then, a 5ml sterile EP tube was placed on the mucosa of the lower lip of the patients, and the subjects were guided to let the saliva flow naturally. The collected volume was 1ml, and they were not allowed to cough up phlegm. The collected saliva samples should be transferred to a -80℃ refrigerator for storage and future u

次要指标

Outcome:

Serum inflammatory factor profile

Type:

Secondary indicator

测量时间点:

术前1天、术后第3天

测量方法:

分别于术前1天、术后第3天收集正常诊疗剩余的外周静脉血 3 mL 后迅速装入 EDTAK2抗凝管,30 min 内在 4℃离心机以 3000 转/分离心 10 min,吸取血浆转移至两个 1mL EP 管,保存于-80℃冰箱中。通过ELISA法检测IL-1β、IL-6和TNF-а。

Measure time point of outcome:

One day before the operation and the third day after the operation

Measure method:

Three mL of peripheral venous blood remaining from normal diagnosis and treatment was collected one day before the operation and on the third day after the operation respectively, and then quickly placed into EDTAK2 anticoagulant tubes. Within 30 minutes, the plasma was separated at 3000 RPM in a 4 ° C centrifuge for 10 minutes, and then transferred to two 1mL EP tubes and stored in a -80 ° C refrigerator. IL-1β, IL-6 and TNF- α were detected by ELISA.
