Wnt signals widely exist in live creatures,involved in many physical or pathological processes,including the cell prolif-eration, differentiation and apoptosis. Recent studies show that Wnt/β-catenin signaling pathway may play an important regula-tory role in the protective effects of neurovascular unit in ische-mic stroke. Some chemicals,such as sulindac and estradiol,and some compound traditional Chinese medicine which contains gly-coside( e. g. rhodiola rosea ) , volatile oil ( e. g. turmeric ) and compound prescription ( e. g. Dan Long Xing Nao Fang ) can protect the neurovascular unit by regulating the pathway. This aims to review the research progress of the protective effects of Wnt/β-catenin signaling pathway on the neurovascular unit in is-chemic stroke,with combination of chemicals and traditional Chi-nese medicine which can protect the neurovascular unit via Wnt/β-catenin signaling pathway. It aims to provide the methodology basis for elucidating the mechanism of drugs,and also provide a new idea for researching the new drug which can reduce the dis-ability rate caused by sequela of stroke.

This review explains the concept of cardiac rehabilitation (CR), clarifies the benefits of CR, and analyses the role of nurses in CR, the obstacles and countermeasures in promoting CR, and the specific problems in implementing cardiac rehabilitation in China. It also points out the research direction in the future, and provides the basis for the development of CR nursing model for the elderly in the future.

In 2022, the World Falls Guidelines Working Group released the World Guidelines for Falls Prevention and Management for Older Adults. This article interprets the important recommended content of the guidelines, aiming to provide clinical medical and nursing staff with the latest evidence-based evidence, promote the clinical conversion of evidence, and provide the best guidance for medical and nursing work in China.

This article provides an interpretation of the newly added sections in the 2023 guidelines titled Cardiovascular Disease: Risk Assessment and Reduction, Including Lipid Modification published by the National Institute for Health and Care Excellence (NICE). The new sections cover various aspects such as risk assessment tools for the primary prevention of cardiovascular disease (CVD), cardiovascular protective diets, and the use of aspirin and statins for both primary and secondary prevention of CVD. This interpretation aims to provide scientific guidance for CVD risk assessment and reduction in China.

The interaction of gut microbiota and its metabolites with the host not only plays an important role in maintaining gut homeostasis and host health, but also is a key link in responding to pathogen infections. A thorough understanding of the changes in gut microbiota and its metabolites during infection, as well as their role and mechanism in host defense against infection, is helpful to guide anti-infection treatment. This review focuses on the role of gut microbiota and their metabolites in host defense against bacterial, fungal, and viral infections, and reveals that they can exert anti-infection effects through resistance mechanisms (inducing antimicrobial substances, training immunity, inhibiting pathogen respiration, directly neutralizing pathogens, immune regulation) and tolerance mechanisms (altering energy metabolism patterns of microbiota, cell proliferation and tissue damage repair, maintaining physiological signal transduction in extraintestinal organs, inflammation regulation, maintaining the integrity of the intestinal barrier), and also summarizes measures to regulate gut microbiota against pathogen infections, in order to provide more ideas for novel anti-infection prevention and treatment strategies targeting gut microbiota and its metabolites.

Objective:To get a deep understanding of true feelings of nurses using intelligent nursing technology in intelligent hospital and to provide basis for optimizing the use, management and promotion of intelligent nursing technology.Methods:By using the phenomenological approach of qualitative research, 15 clinical nurses in a Class Ⅲ Grade A hospital (Intelligent Hospital) in Chongqing from April to June 2019 were selected for face-to-face in-depth interviews. Colaizzi analysis was used to analyze the data.Results:The true experience of nurses in the intelligent hospital on intelligent nursing technology was summarized into four main themes, including the experience of intelligent nursing, lack of adequate equipment and technical support, some time needed for learning and mastering new technologies and full of earnest expectations for intelligent nursing technology.Conclusions:The managers of intelligent hospitals should pay attention to the real feeling of nurses using intelligent nursing technology, solve the problems encountered in use in time, do a good job in communication, feedback and training and optimize the evaluation index of nursing quality in time.
