Objective To explore the impact of wearable devices in assisting disease monitoring on heart-focused anxiety in patients with tachyarrhythmias. Methods A cross-sectional study design was conducted. 305 patients with tachyarrhythmias who attended the department of cardiology of Zhongshan Hospital, Fudan University in Shanghai from July 2025 to December 2025 were enrolled as the research subjects, and clinical data of patients were collected. Univariate analysis and multiple stepwise regression analysis were used to analyze the impact of wearable devices in assisting disease monitoring on patients’ heart-focused anxiety. Results The mean score of heart-focused anxiety in the 305 patients with tachyarrhythmias was 33.16±9.70. Among them, 104(34.10%) patients used wearable devices in assisting disease monitoring. The results of univariate analysis and multiple stepwise regression showed that the use of wearable devices in assisting disease monitoring was an influencing factor for heart-focused anxiety (P＜0.05), and the patients who used wearable devices in assisting disease monitoring had a significantly lower level of heart-focused anxiety (P＜0.05). Conclusions The use of wearable devices in assisting disease monitoring is associated with a lower level of heart-focused anxiety in patients with tachyarrhythmias. Medical staff can guide patients to rationally use wearable devices in assisting disease monitoring on the basis of evaluating their needs and device operation capabilities.

AIM:To clarify the expression characteristics and regulatory role of the long non-coding RNA(lncRNA)metastasis-associated lung adenocarcinoma transcript 1(MALAT1)in oxidative stress and apoptosis of H2O2-induced human lens epithelial cell line HLE-B3.METHODS: HLE-B3 cells were divided into Control group and H2O2 group(cultured with 200 μmol/L H2O2 for 24 h). Levels of reactive oxygen species(ROS)and cell apoptosis rates were detected by flow cytometry. Activities of superoxide dismutase(SOD)and catalase(CAT)were measured using kits, MALAT1 expression was quantified by real-time quantitative PCR, and its cellular localization was determined by fluorescence in situ hybridization. After selecting the Si-MALAT1 sequence with the highest silencing efficiency, the groups were established as Control, H2O2, H2O2+Si-NC, and H2O2+Si-MALAT1. Immunofluorescence staining was employed to detect the apoptosis marker TUNEL and Nrf2 nuclear translocation. RESULTS:Compared with the Control group, the H2O2group exhibited significantly elevated ROS levels, markedly decreased SOD and CAT activities(both P<0.001), and a significantly increased apoptosis rate(P<0.01). MALAT1 expression was upregulated(P<0.01)and localized in the nucleus. After silencing MALAT1, H2O2-induced cell apoptosis was significantly inhibited(P<0.01).CONCLUSION: H2O2-induced oxidative stress can increase the expression of MALAT1, and silencing MALAT1 reduces oxidative stress damage and apoptosis, providing a potential target for preventing and treating cataracts.

Video-assisted thoracoscopic surgery (VATS) is the standard procedure for the treatment of lung cancer in the early and middle stages in recent years. The diaphragm is the main respiratory muscle that maintains effective pulmonary ventilation. Diaphragmatic dysfunction is a short-term or permanent dysfunction of one or both diaphragms caused by various factors, mainly manifested as diaphragm distension, diaphragm weakness and diaphragm paralysis, which can lead to respiratory dysfunction, even respiratory failure. This article reviews the etiology, clinical symptoms and signs, diagnosis, treatment and prognosis of diaphragmatic dysfunction after VATS lobectomy, aiming to provide clinicians with assessment methods and management framework for timely diagnosis and treatment of diaphragmatic dysfunction after VATS lobectomy, so as to optimize postoperative respiratory rehabilitation and improve long-term prognosis and quality of life of patients.

The theory of " heart governing the exterior" derives from Prohibition of Pricking in Suwen, which has an important position in the clinical practice of traditional Chinese medicine. This article sorts out the interpretation of " heart governing the exterior" of physicians in the past dynasties, and summarizes the clinical application of " heart governing the exterior" in chest painful impediment, warm disease, dermatosis, allergic rhinitis, tic disorder, and diabetic neuropathy. It is found that the theory of " heart governing the exterior" is widely used in clinical practice and has good effects. This paper further expands and enhances its theoretical connotation, that is, the physiological and pathological connection and clinical application of the three dimensions of heart yang, heart blood, and heart spirit with the life and mental activities dominated by it, as well as the overall external performance. In addition, by exploring the relationship between " heart governing the exterior" and " brain-heart axis" , " brain-skin axis" in Western medicine, it indirectly confirms the rationality of " heart governing the exterior" in Western medicine, and lays the foundation for the further development and application of the theory of " heart governing the exterior" .

AIM: To design and construct recombinant epitope nucleotides vaccine of glycoprotein B(gB)and glycoprotein D(gD)of herpes simplex virus type 1(HSV-1), and to investigate its immunoprotective effects and tissue expression in animal models.METHODS: The HSV-1 gB and gD epitope genes were selected and tandem assembled to construct the recombinant protein-coding gene X, which was transducted into the prokaryotic expression vector pET28(a). The recombinant protein was synthesized and utilized to generate monoclonal antibodies, which were subsequently used to immunize New Zealand white rabbits. The immunogenicity of the purified protein and the presence of polyclonal antibodies in the serum were tested through separating serum from cardiac blood, and the serum antibody titers were determined. The pcDNA3.1-X was successfully constructed as a eukaryotic expression vector and immunized the female BALB/c mice aged 4 to 6 wk via intramuscular injection. Serum antibodies and immune-related cytokines were quantified using enzyme-linked immunosorbent assay(ELISA). The expression of the X protein in the ocular, trigeminal ganglion, and brain tissues of the mice was assessed.RESULTS: The target polyclonal antibody was identified with a serum antibody titer of 1:3200 in the rabbit serum after immunized by recombinant protein X. Upon immunizing mice with the eukaryotic recombinant plasmid pcDNA3.1-X, the concentration of HSV-1 serum IgM antibodies of the experimental group was 12.13±0.85 ng/L, which was significantly higher than that of the vector control group(0.49±0.44 ng/L; t=21.07, P<0.001). The concentrations of cytokines interleukin IL-2, IL-4, IL-10, and IFN-γ in the experimental group were 11.63±0.60, 22.65±1.47, 85.75±14.12, and 114.90±6.39 ng/L, respectively, all of which were significantly higher than those in the vector control group and the blank control group(all P<0.05). Immunohistochemical staining revealed the presence of target protein X in the eyeball, trigeminal ganglion, and brain tissue.CONCLUSION: The HSV-1 gB and gD tandem epitope nucleotides vaccine pcDNA3.1-X was successfully constructed, which activates a remarkable immune response and is stably expressed in the eyeball, trigeminal ganglion, and brain tissue. This study provides a foundation for further research of an HSV-1 recombinant antigen epitope tandem vaccine.

Objective:To investigate the prognostic value of aldosterone synthase (CYP11B2) immunohistochemical expression in adrenal specimens for surgical outcomes of primary aldosteronism (PA).Methods:The clinical data of 99 patients who underwent total unilateral adrenalectomy from June 2022 to January 2023 at Beijing Anzhen Hospital was retrospectively analysed. The clinical data of 99 patients who underwent unilateral total adrenalectomy at Beijing Anzhen Hospital from June 2022 to January 2023 were retrospectively analyzed.There were 59 patients in the PA group, age (53.02±10.56) years, body mass index (BMI) (26.28±4.33) kg/m 2, preoperative aldosterone 29.0(15.9, 61.5)ng/dl, plasma renin 1.3(0.6, 2.8)μIU/ml, aldosterone renin ratio (ARR) 19.3(9.1, 59.2) μg/μIU, preoperative potassium (3.60±0.69) mmol/L, and systolic blood pressure (156.54±21.39) mmHg (1 mmHg=0.133 kPa).There were 40 cases in the nonfunctioning adenoma (NFA) group, age (57.23±9.39) years, BMI (27.07±3.46) kg/m 2, preoperative aldosterone 9.0(7.2, 14.1) ng/dl, plasma renin 18.0(5.2, 47.6)μIU/ml, ARR 0.6(0.2, 1.4) μg/μIU, preoperative potassium (4.17±0.41) mmol/L, and systolic blood pressure (157.97±26.87) mmHg. The differences between the two groups were statistically significant for potassium ( P<0.01), aldosterone ( P=0.012), renin ( P<0.01), and ARR ( P<0.01).Surgical outcomes were assessed using the Consensus on the Outcome of Surgery for Primary Aldosteronism (PASO) (complete/partial/no success for clinical and biochemical outcomes). CYP11B2 expression was evaluated by immunohistochemistry using the 2022 World Health Organization's histopathology of primary aldosteronism (HISTALDO) criteria. The correlation between the expression of CYP11B2 and surgical outcomes was assessed. Results:The mean follow-up of 99 patients was (11.73±4.92) months. Of these, 36 out of 59 PA patients had positive CYP11B2 expression in their adrenal specimens, while 23 were negative; all 40 NFA patients were negative for CYP11B2. Among the 36 CYP11B2-positive PA patients, there were 19 cases of aldosterone-producing adenomas, 3 aldosterone-producing nodules, 4 aldosterone-producing micronodules, 8 multiple aldosterone-producing micronodules, and 2 aldosterone-producing diffuse hyperplasia. 36 cases of CYP11B2-positive PA patients had complete clinical success in 15 cases, partial success in 20 cases, and no success in 1 case, and complete biochemical success in 24 cases, partial success in 11 cases, and no success in 1 case; 23 CYP11B2-negative PA patients had complete clinical success in 4 cases, partial success in 15 cases, and no success in 4 cases, and complete biochemical success in 6 cases, partial success in 15 cases, and no success in 2 cases. Adrenal specimens from CYP11B2-positive PA patients had significantly better clinical ( P=0.038) and biochemical ( P=0.008) success rates than CYP11B2-negative PA patients. Patients with aldosterone-producing adenomas had complete clinical success in 8 cases, partial success in 11 cases, and no success in 0 cases, and biochemical success was completely achieved in 16 cases, partially achieved in 2 cases, and not successful in 1 case. They also had significantly higher clinical ( P=0.028) and biochemical ( P<0.01) success rates compared to CYP11B2-negative PA patients. Conclusions:Patients with PA who had immunohistochemical staining for CYP11B2 positivity and high expression in adrenal specimens had a better postoperative clinical and biochemical prognosis. Patients with aldosterone-producing adenomas had the greatest postoperative outcome of all pathological subtypes of PA.

Silver nanoparticles(AgNPs)are employed as disinfectants due to their extensive antimi-crobial properties,but their biosafety in the livestock industry has not been comprehensively as-sessed.In this study,16 Black-skin Red-crowned chickens aged 32 weeks were randomly divided in-to four groups and sprayed with AgNP solution at the concentration of 0,0.064,0.128 or 0.256 g/L,respectively,every 72 h in their coops for 30 d.The effects of AgNPs as the disinfectant on lung tissue in chicken were investigated through calculation of organ coefficients,observation of lung tissue sections,analysis of bronchoalveolar lavage fluid,measurement of inflammatory factors,de-tection of silver residue in lung tissue,and exploration of signaling pathways in pulmonary fibrosis.The results indicated that chickens in the 0.128 and 0.256 g/L AgNPs treatment groups showed the blurred pulmonary lobule boundaries,the destroyed alveolar structure,and the significant in-crease in pulmonary fibrosis.These pathological changes were accompanied by the decrease in lung organ coefficient,the reduced SP-C content,the increased total protein concentration in lavage flu-id,and the elevated LDH and silver content in lung tissue.The levels of IL-6 and TNF-α in the 0.128 and 0.256 g/L AgNPs treatment groups were significantly higher than the control group,which suggested that AgNPs exposure could induce the pulmonary inflammatory responses.High concentrations of AgNPs can trigger pulmonary tissue fibrosis,damaging the structure and func-tions of lungs.The relative mRNA expression levels of NF-κB in all AgNPs treatment groups,TGF-β in the 0.128 g/L AgNPs treatment group,and Smad3 in the 0.128 and 0.256 g/L AgNPs treatment groups were significantly higher than these in the control group,respectively.Spraying chickens with 0.128 or 0.256 g/L AgNPs for disinfection led to pulmonary deposition of AgNPs,causing direct structural and functional damages to the lungs.It could also induce the chronic pul-monary inflammation through the NF-κB pathway and promote the TGF-β/Smad3 pathway to in-crease collagen synthesis,leading to pulmonary fibrosis.Therefore,the application of high concen-trations of AgNPs in livestock farming requires careful consideration of their potential biological safety issues.

With the widespread application of nuclear technology,the prevention and treatment of radiation damage have become significant issues in the fields of public health and medicine.This article reviews the adverse drug reactions and their monitoring for radioprotective drugs,and discusses their post-marketing re-evaluation in terms of safety,efficacy,economics,and quality standards.Research indicates that while there is a wide variety of radioprotective drugs,safety concerns are prevalent.Future efforts should focus on strengthening the monitoring and management of adverse drug reactions,optimizing drug safety,and exploring the potential of combined drug applications through multidisciplinary collaboration to enhance anti-radiation efficacy.
