Objective:To explore the latent classes of fear of childbirth in late pregnancy women and its relationship with sense of coherence, providing reference for precise support interventions in clinical practice.Methods:From January to September 2023, convenience sampling was used to select 304 pregnant women who underwent antenatal examination at the Obstetrics Clinic of Affiliated Hospital of Hangzhou Normal University as participants. The General Information Questionnaire, Childbirth Attitudes Questionnaire, and the Sense of Coherence Scale-13 (SOC-13) were used for questionnaire survey. Latent profile analysis was used to explore the categories of fear of childbirth in late pregnancy women, and analyzed differences of SOC-13 scores among women with different categories of fear of childbirth.Results:Fear of childbirth in 304 late pregnant women was divided into three latent classes, including low-level fear group of (50.0%, 152/304), moderate-level fear group of (35.2%, 107/304), and high-level fear group of (14.8%, 45/304). ANOVA analysis showed that there were statistically significant differences in total score and dimension scores of SOC-13 among late pregnancy women with three different classes of fear of childbirth ( P<0.05) . Conclusions:There are three latent classes of fear of childbirth in late pregnancy women. The sense of coherence among pregnant women affects their fear of childbirth. Nursing staff should address the heterogeneity of fear of childbirth in late pregnancy women, starting from sense of coherence, and take targeted intervention measures to reduce the fear of childbirth in late pregnancy women.

Objective:To investigate the application value of virtual simulation experiment in the teaching of Laboratory Sciences for Virus Infection Testing.Methods:Undergraduate students(n=58)majoring in Health Inspection and Quarantine of grade 2020 were selected as the research objects.The"Virtual simulation experiment of influenza virus isolation and identification in BSL-2 laboratory"was included in the teaching of Laboratory Sciences for Virus Infection Testing.The application effect of the virtual simulation experiment was evaluated by a self-designed questionnaire.Results:A total of 50 students completed the questionnaire effectively.After completing the virtual simulation experiment,96.0%of the students thought that the simulation degree of the experiment was high.Students could understand the instrument composition,internal structure,operation process,and matters needing attention.And 52.0%of the students thought that the experiment had an impact on autonomous learning.Students believed that the experiment could improve their interest in the course(88.0%),increase their mastery of theoretical knowledge(60.0%),and improve their ability to analyze and solve problems(46.0%).And 72.0%of the students thought that the running speed of the virtual simulation experiment was slow.The top three advantages of the experiment evaluated by students were easy operation,no damage to the instrument and no worry about the dangers in the experiment,and helpful to understand the knowledge.The top three disadvantages of this experiment were no improvement in practical ability,no familiarity with the use of instruments,different feelings from the real experiment and too idealized experimental process.And 66.0%of the students thought that virtual simulation experiments should complement traditional experimental teaching.Conclusions:Virtual simulation experiment can carry out dangerous experiments that are difficult to perform in traditional laboratories.It can improve students'mastery of theoretical knowledge,enhance their interest in learning,and improve their ability to analyze and solve problems.However,there are still some problems in its application,which should be combined with traditional experimental teaching to improve the teaching effect.

Colorectal cancer is one of the common malignant tumors of the digestive tract.With the popularization of screening methods and advancement of endoscopic technology,an increasing number of T1 stage colorectal cancers can be discovered.Accurately predicting lymph node metastasis risk is significantly important for guiding clinical treatment decisions,reducing complications and mortality.Current research on risk factors for lymph node metastasis in T1 stage colorectal cancer covers multiple aspects including clinical pathological features,molecular phenotypes and genetic characteristics.Some studies have built prediction models by integrating these factors,which show higher sensitivity,specificity and accuracy compared to current clinical guidelines.These models provide valuable experience for clinical practice.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.

Objective Summarizes the current research status of defensive medicine in China and provides references for future research.Methods The search period spans from the inception of the database to March 2024.CNKI,Wan-fang Data,Web of Science,PubMed databases were queried,followed by literature screening based on predeter-mined inclusion and exclusion criteria.The current landscape of defensive medicine research in China was synthe-sized and categorized based on fundamental research characteristics,measurement methodologies,influencing fac-tors,and other relevant aspects.Results A total of 24 Chinese literature sources and 4 foreign literature sources were incorporated,indicating a prevalent occurrence of defensive medicine in China.Measurement tools for defen-sive medicine exhibit variability across different studies.Key influencing factors encompass doctor's demographic vari-ables such as gender,age,and professional status,institutional factors like legal frameworks and medical in-surance,and sociol-cultural factors such as doctor-patient relationships and adverse public perceptions.Conclusion Defensive medicine is relatively widespread and influenced by various factors in China.It's urgent to explore the for-mation mechanism of defensive medicine from multiple perspectives and provide evidence for passive defen-sive medicine governance.
