Study design:

Cohort study 

研究目的:

通过宏基因组分析及代谢组学分析获得普外患者术后不同衰弱状态变化中的肠道和口腔菌群及相关代谢产物变化特征,明确差异靶点,揭示其与术后衰弱发生的相关性。  

Objectives of Study:

Through metagenomic analysis and metabolomics analysis, the changes in intestinal and oral microbiota and related metabolites during different states of postoperative frailty in patients with general surgery were obtained, the differences in target points were identified, and the correlation between these changes and the occurrence of postoperative frailty was revealed.

Description for medicine or protocol of treatment in detail:

 

纳入标准:

年龄≥60岁;普通外科住院期间进行择期4级腹部外科手术的患者;同意提供唾液及粪便样本。

Inclusion criteria

Age >= 60 years; Patients undergoing elective grade 4 abdominal surgery during general surgery hospitalization; Agree to provide saliva and fecal samples.

排除标准:

术前存在严重肠道菌群失调;发生严重感染需长期抗感染治疗的患者;3个月内接受益生菌制剂;存在严重口腔疾病及口腔炎症史(评价标准:1)临床诊断标准:活动性牙周炎(牙周袋深度≥5mm,探诊出血);口腔溃疡面积≥1cm2或持续>2周;急性化脓性腮腺炎或颌面部蜂窝织炎;重度龋齿,即累及牙髓或需根管治疗。2)辅助检查:口腔科医生通过临床检查及影像学(如全景X光片)评估确认);存在严重心、肺、肝、肾功能不全(评价标准均严格遵循国际权威指南定义严重器官功能不全:心功能采用NYHA III-IV级或ACC/AHA Stage C-D期;肺功能依据GOLD 3-4级;肝功能参考Child-Pugh C级或肝功化验指标超正常两倍以上;肾功能基于KDIGO G4-G5期,以确保研究人群安全性及数据可靠性)。

Exclusion criteria:

There was severe intestinal flora imbalance before the surgery; patients with severe infections requiring long-term anti-infection treatment; those who received probiotic preparations within 3 months; patients with severe oral diseases and a history of oral inflammation (evaluation criteria: 1) Clinical diagnostic criteria: active periodontitis (periodontal pocket depth ≥ 5mm, bleeding on probing); oral ulcer area ≥ 1cm2 or lasting > 2 weeks; acute suppurative parotitis or maxillofacial cellulitis; severe caries, involving the dental pulp or requiring root canal treatment. 2) Auxiliary examinations: The oral doctor confirmed through clinical examination and imaging (such as panoramic X-ray) assessment; there were severe heart, lung, liver, and kidney function impairments (evaluation criteria strictly follow the definitions of severe organ dysfunction in international authoritative guidelines: cardiac function using NYHA III-IV grade or ACC/AHA Stage C-D period; pulmonary function based on GOLD 3-4 grade; liver function referring to Child-Pugh C grade or liver function test indicators more than twice the normal value; kidney function based on KDIGO G4-G5 stage to ensure the safety of the study population and the reliability of the data).
