Objective:To investigate the association between dietary diversity and the risk of major adverse cardiovascular events (MACE) after percutaneous coronary intervention (PCI) in patients with coronary heart disease (CHD) .Methods:A total of 553 patients diagnosed with CHD and undergoing PCI in the Department of Cardiology at the Second Affiliated Hospital of Harbin Medical University between May and November 2023 were enrolled using a convenience sampling method. A Semi-Quantitative Food Frequency Questionnaire was used to assess patients' dietary intake after PCI, and the Dietary Diversity Score (DDS) was calculated. Patients were followed up for one year to determine the incidence of MACE.Results:History of hypertension, history of hyperlipidemia, body mass index, use of antiplatelet agents, use of diuretics, triglycerides, smoking index and DDS were identified as factors influencing the occurrence of MACE after PCI ( P<0.05) . Among these, higher dietary diversity had a protective effect against MACE. Conclusions:After PCI, patients with lower DDS experienced MACE more frequently than those with higher scores. Increased dietary diversity can effectively help prevent MACE in patients after PCI.

Clinical practice guidelines represent the best recommendations for patient care. They are developed through systematically reviewing currently available clinical evidence and weighing the relative benefits and risks of various interventions. However, clinical practice guidelines have to go through a long translation cycle from development and revision to clinical promotion and application, facing problems such as scattered distribution, high duplication rate, and low actual utilization. At present, the clinical practice guideline information platform can directly or indirectly solve the problems related to the lengthy revision cycles, decentralized dissemination and limited application of clinical practice guidelines. Therefore, this paper systematically examines different types of clinical practice guideline information platforms and investigates their corresponding challenges and emerging trends in platform design, data integration, and practical implementation, with the aim of clarifying the current status of this field and providing valuable reference for future research on clinical practice guideline information platforms.

Prone position ventilation (PPV) is an important protective strategy for lung ventilation, widely used in clinical practice, especially since the novel coronavirus infection pandemic. Since PPV is a non-physiological position, improper implementation and management can lead to serious adverse events such as pressure injury, facial edema, unplanned extubation and (or) reintubation, and even asphyxia. At present, preventive and protective strategies are mainly used to manage PPV-related complications in clinical practice. These strategies not only increase the workload of medical staff and the use of consumables, but also increase the medical cost of patients, further burdening patients and their families economically. To overcome the above problems, the medical staff of the department of critical care medicine of Tianjin Third Central Hospital designed a prone position head auxiliary support device and obtained a national utility model patent (patent number: ZL 2022 2 1751906.3). The device consists of annular plate, folding plate, support frame, reflector and wheel bodies. It serves to reduce pressure on the head and facial skin, while also exposing the mouth, nose, eyes, and ears to the hollow position of the annular plate according to the patient's position. At the same time, the patient's face or side skin can be observed through the lower reflector. The height of the annular plate was adjusted by adjusting the support frame, and the head was raised to reduce facial edema. The setting of strip groove, through hole and hook can sort out the facial pipeline, keep the drainage unobstructed, prevent catheter displacement and unplanned extubation, and has certain clinical promotion and practical value.
