Objective  To retrospectively analyze the intervention effect of humanized nursing based on Watsons caring theory in elderly patients with non-small cell lung cancer (NSCLC) after operation. Methods  A total of 107 elderly patients who had undergone NSCLC surgery in our hospital from May 2023 to September 2024 were selected. Among them, patients from May 2023 to January 2024 were assigned to a control group (54 cases), and patients from February to September 2024 were assigned to an observation group (53 cases). The control group received routine nursing, while the observation group received humanized nursing guided by Watson's caring theory in addition to routine nursing. The postoperative complication rate, as well as self-care ability ［assessed by the exercise of self-care agency scale (ESCA)］, self-management efficacy ［assessed by the strategies used by people to promote health (SUPPH)］ and psychological state ［assessed by the Hamilton anxiety scale (HAMA) and the Hamilton depression scale (HAMD)］ scores before and after intervention were compared between the two groups. ResultsCompared with the control group (20.37%), the observation group showed a significantly lower postoperative complication rate (5.66%), with a statistically significant difference (P＜0.05). Compared with the control group after intervention, the observation group exhibited significantly increased ESCA and SUPPH scores, as well as significantly decreased HAMA and HAMD scores after intervention (all P＜0.001). Conclusion  The application of humanized nursing based on Watson's caring theory in elderly patients after NSCLC surgery could regulate their psychological state, improve the level of self-management efficacy and self-care ability, and reduce the incidence of postoperative complications.

Objective  To understand the perception of stroke risk and its influencing factors in patients with atrial fibrillation (AF), and to provide reference for formulating targeted preventive measures. Methods  Using purposive sampling method, 15 inpatients with AF were selected as research subjects for face-to-face semi-structured interviews. The interview data were collated and analyzed using the Colaizzi's 7-step method for phenomenological data analysis. Results  Three themes were extracted, comprising 10 subthemes: cognition of stroke risk (weak fundamental knowledge of AF and inconsistent perception of stroke risk); promoting factors for risk perception (fundamental support of health literacy, empowering value of authoritative information, awakening effect of personal experience and synergistic reinforcement effect of social support); hindering factors for risk perception (predicament and biases in information acquisition, cognitive interference of disease characteristics, negative influence of social psychology and limiting factors of the external environment). Conclusion  The perception of stroke risk in patients with AF presents multi-dimensional and complex characteristics, with their cognitive level being jointly influenced by multiple factors. Clinical medical staff should formulate individualized intervention measures based on the key influencing factors to improve patients correct cognition and perception ability of stroke risk.

Interstitial lung disease (ILD) is one of the most severe pulmonary complications of rheumatoid arthritis (RA), significantly increasing the risk of mortality and disability in affected patients. Early and accurate assessment of disease risk, progression, and prognosis is crucial for improving patients' outcomes. Although currently the clinical diagnosis of rheumatoid arthritis-associated interstitial lung disease (RA-ILD) relies mainly on high-resolution CT scans and pulmonary function tests, these methods still have significant shortcomings in early screening and disease course monitoring. Therefore, the exploration of reliable and non-invasive biomarkers has emerged as a critical direction in current research. This article reviews the latest research progress on biomarkers related to RA-ILD, and discusses the current application status of omics technologies in this field.

Patients with ischemic stroke frequently experience concurrent arrhythmias, the most common of which is atrial fibrillation. Atrial fibrillation detected after stroke (AFDAS) may represent a clinical entity distinct from known AF identified prior to the stroke. AFDAS is associated with an increased risk of stroke recurrence, but its pathogenesis is complex and encompasses multiple pathophysiological processes. It is currently believed to likely involve complex changes in the central autonomic network and humoral regulation, such as autonomic nervous system dysfunction, immune and inflammatory responses, and atrial remodeling. An in-depth exploration of these mechanisms contributes to the development of more precise and effective strategies for the prevention and treatment of AFDAS.

Cardiovascular diseases have become a major burden on the social healthcare system due to their high incidence and mortality. Noninvasive cardiac output measurement technology, with its core advantages of being real-time, noninvasive, and enabling continuous monitoring, can accurately capture dynamic changes in cardiac function. This opens new pathways for the prevention, diagnosis, treatment, and rehabilitation of cardiovascular diseases. This article primarily reviews the application and progress of noninvasive cardiac output measurement technology in the cardiac function evaluation and cardiac rehabilitation of patients with coronary artery disease, hypertension, and heart failure. It analyzes the technology's advantages in precise subtyping, personalized treatment, risk warning, and rehabilitation guidance, aiming to provide reference for promoting its application and development in cardiac assessment and rehabilitation.

目前临床应用的15导联心电图组合方式较多，但由于缺乏统一的操作与诊断规范，因此影响了临床心电图诊断结果的一致性。基于临床心电图检查所遵循的“操作简便、费用相对低廉，能较全面反映心脏电活动”的原则，该共识推荐的同步15导联心电图描记方法是将标准12导联以外的3个电极分别放置于右胸的V3R、V4R导联及后壁V7导联的位置，患者保持平卧位即可完成操作。15导联心电图通过V3R、V4R导联探查右心室外侧壁的心电活动，并经V7导联了解左心室后壁的心电现象，实现了对标准12导联探查盲区的有效补充。为规范同步15导联心电图的操作方法，河南省生物医学工程学会心电诊断与技术专委会联合中国医药生物技术协会心电学分会动态心电专业组、中国药文化研究会医药科教分会等学会，组织相关专家经过反复充分讨论，共同编写了本共识。本共识建议在临床上，特别是心电图室或心电网络终端配备15或18导联心电图机的单元进行规范化常规应用。
