- The observation group (Type: EXPERIMENTAL): During the 15-day treatment, both groups of patients are hospitalized, while conventional care and enteral nutrition support are provided to the two groups. Specifically, conventional care includes health education, dietary adjustments, nasopharyngeal hygiene, management of risk factors (blood pressure and lipid control, etc.), exercise rehabilitation, and psychological support. The frequency and content of these interventions are arranged based on the patients\&#39; health condition. The observation group receives IOE for enteral nutrition support
- The control group (Type: ACTIVE_COMPARATOR): During the 15-day treatment, both groups of patients are hospitalized, while conventional care and enteral nutrition support are provided to the two groups. Specifically, conventional care includes health education, dietary adjustments, nasopharyngeal hygiene, management of risk factors (blood pressure and lipid control, etc.), exercise rehabilitation, and psychological support. The frequency and content of these interventions are arranged based on the patients\&#39; health condition.The control group receives NGT for enteral nutrition support
