With the support of partial dual temperature monitoring (comparing the specific difference between standardized axillary temperature monitoring and esophageal temperature), this trial is divided into the following three parts:
1. Multi center observational study: Establish and validate a dynamic incremental training intraoperative hypothermia prediction model - Intelligent Care for the Elderly (ICE) - Intraoperative hypothermia warning system, and provide ICE Offline for use by healthcare professionals and ICE Online for further model updates when needed for clinical or research purposes.
2. Multi center non randomized controlled clinical trial: Conduct a multi center stratified temperature management clinical trial based on ICE Offline after dynamic incremental training to verify the clinical and economic benefits of the model and active warming.
3. Pre and post comparative study: Collect data before ICE application and compare it with data after ICE promotion.

Efficacy and Safety of Transbronchial BTVA in Heterogeneous Emphysema: A Prospective, Single-Arm, Multicenter Clinical Study

Colorectal cancer is one of the malignant tumours with high morbidity and mortality worldwide, posing a serious threat to human health. In recent years, the incidence of colorectal cancer has been on the rise with changes in lifestyle and dietary habits. Although some progress has been made in treatments such as surgery, chemotherapy and radiotherapy, however, the early diagnosis, prognosis assessment and personalised treatment of colorectal cancer still face great challenges. Therefore, it is of great academic value and practical significance to deeply explore the influencing factors of colorectal cancer occurrence, development and its prognosis, especially the research on environmental factors and metabolomics.
