Identifying symptom clusters and temporal interconnections in patients with lung tumors after CT-guided microwave ablation: A network analysis.

PURPOSE: To explore symptom clusters and interrelationships using a network analysis approach among symptoms in patients with lung tumors who underwent computed tomography (CT)-guided microwave ablation (MWA). METHODS: A longitudinal study was conducted, and 196 lung tumor patients undergoing MWA were recruited and were measured at 24 h, 48 h, and 72 h after MWA. The Chinese version of the MD Anderson Symptom Inventory and the Revised Lung Cancer Module were used to evaluate symptoms. Network analyses were performed to explore the symptom clusters and interrelationships among symptoms. RESULTS: Four stable symptom communities were identified within the networks. Distress, weight loss, and chest tightness were the central symptoms. Distress, and weight loss were also the most key bridge symptoms, followed by cough. Three symptom networks were temporally stable in terms of symptom centrality, global connectivity, and network structure. CONCLUSION: Our findings identified the central symptoms, bridge symptoms, and the stability of symptom networks of patients with lung tumors after MWA. These network results will have important implications for future targeted symptom management intervention development. Future research should focus on developing precise interventions for targeting central symptoms and bridge symptoms to promote patients' health.

Nurses' perspectives on professional self-concept and its influencing factors: A qualitative study.

BACKGROUND: Nurses with a strong professional self-concept tend to exhibit a positive mindset and strong work engagement, delivering high-quality patient care. Although numerous quantitative studies have examined the factors impacting professional self-concept, there remains a limited exploration of these factors from the perspective of nurses themselves. METHODS: This qualitative descriptive study uses the PERMA theory and Social Cognitive Theory as the theoretical framework. Semi-structured interviews were conducted with 15 nurses from six public hospitals in China. The data were analyzed thematically using a combination of inductive and deductive approaches. RESULTS: Nurses' understanding of professional self-concept could be divided into four categories: professional identity, competence, care, and knowledge. Factors influencing nurses' professional self-concept were categorized into eight subthemes in three domains: (1) personal factors, including psychological qualities and attitude towards the nursing profession; (2) occupational-related behavioral factors, including role-oriented behavior and knowledge-oriented behavior; and (3) work environment and external factors, including external evaluation and perceptions of nurses, time allocation, nursing work tasks, work atmosphere, school education, and perceived supports. CONCLUSIONS: This study found that, although nurses had different personal experiences, their perceptions of professional self-concept were similar. Nurses' professional self-concept is a multidimensional concept and involves various factors, such as personality, work-related characteristics, environment, and family. To thrive in a nursing career, nurses must discern the factors that can enhance or hinder their professional self-concept. By identifying and adjusting these factors, personalized support and positive interventions can be tailored to meet nurses' specific needs, which ultimately nurtures their professional development. TRIAL REGISTRATION: This study was registered on December 14, 2022, in the Chinese Clinical Trial Registry (ChiCTR2200066699) as part of our ongoing study.

Effect of multidisciplinary collaborative empowerment education on psychological distress and quality of life in patients with colorectal cancer undergoing chemotherapy.

PURPOSE: To evaluate the effects of multidisciplinary collaborative empowerment education on psychological distress and quality of life (QoL) in patients with colorectal cancer undergoing chemotherapy. METHODS: A quasi-experimental study was conducted using repeated measures at pre- and post-intervention in the fourth chemotherapy cycle. Sixty patients with colorectal cancer aged 36-84 years were allocated to the intervention and control groups. The intervention group received multidisciplinary empowerment education, while the control group received routine health education. Psychological distress involving depression and anxiety symptoms was assessed using The Kessler Psychological Distress Scale (K10) and QoL was measured using The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTCQLQ-C30). Repeated-measures analysis of variance was used to examine intervention effects. Statistical analyses were performed using the SPSS software (version 26.0). RESULTS: Psychological distress was considerably lower and QoL was considerably better in patients following multidisciplinary empowerment education in the intervention group than those in the control group. In addition, psychological distress significantly decreased and QoL improved in the intervention group compared to baseline. CONCLUSION: Multidisciplinary collaborative empowerment education was effective in improving the psychological distress and QoL among patients with colorectal cancer undergoing chemotherapy. These findings suggest that the establishment of multidisciplinary collaborative empowerment education might be considered as an innovative means of clinical patient education during combination chemotherapy to improve health outcomes in patients with colorectal cancer. However, our results should be interpreted with caution because of the small sample size. Further validation in a larger sample or randomized controlled design is necessary in the future.

Prior nasal delivery of antagomiR-122 prevents radiation-induced brain injury.

Radiation-induced brain injury is a major adverse event in head and neck tumor treatment, influencing the quality of life for the more than 50% of patients who undergo radiation therapy and experience long-term survival. However, no effective treatments are available for these patients, and preventative drugs and effective drug-delivery methods must be developed. Based on our results, miR-122-5p was upregulated in the mouse radiation-induced brain injury (RBI) model and patients with nasopharyngeal carcinoma (NPC) who received radiation therapy. Intranasal administration of a single antagomiR-122-5p dose before irradiation effectively alleviated radiation-induced cognitive impairment, neuronal injury, and neuroinflammation in the mouse RBI model. Results further indicated that miR-122-5p inhibition in microglia reduced the levels of proinflammatory cytokines and enhanced the phagocytic function to protect against radiation-induced neuronal injury in cell models. Further, we profiled transcriptome data and verified that Tensin 1 (TNS1) may be the target of miR-122-5p in RBI. In summary, our results reveal a distinct role for miR-122-5p in regulating neuroinflammation in RBI, indicating that a non-invasive strategy for intranasal miR-122-5p administration may be an attractive therapeutic target in RBI, providing new insights for clinical trials. Further systematic safety assessment, optimization of drug administration, and clarity of mechanism will accelerate the process into clinical practice.

[Correlation between Indian hedgehog and damage degree of knee osteoarthritis cartilage].

OBJECTIVE: To explore the correlation between the Indian hedgehog and severity of knee osteoarthritis cartilage damage. METHODS: A total of 215 patients with osteoarthritis [97 males and 118 females with an average age of 65.2 ± 7.8 (49-78) years and 34 healthy persons [28 males and 6 females with an average age of 58.4 ± 8.7 (45-62) years were selected randomly and their cartilages in knee joints collected. The damage degree of osteoarthritis was evaluated by revised Markin scale. The Ihh mRNA was assessed by real-time polymerase chain reaction (PCR) and the Ihh protein expression examined by Western blot. RESULTS: According to the revised Mankin scale, the osteoarthritis samples were divided into 3 stages of severe, moderate and mild. Comparing with normal control group, the Ihh mRNA and protein expressions increased obviously in cartilage. With worsening cartilage damage, Ihh mRNA and protein expression increased accordingly. Statistical differences existed among the groups (normal: 1.00 ± 0.01; mild: 1.37 ± 0.02; moderate: 1.90 ± 0.02; severe: 2.13 ± 0.03; P < 0.01). And the damage degree of osteoarthritis was determined by injury extent of soft tissue in knee joint (Mankin scale). And the damage degree of cartilage was positively correlated with Ihh expression (r = 0.581, P < 0.01). CONCLUSION: Ihh expression is correlated with the damage degree of knee joint osteoarthritis.

Latent profiles of academic resilience in undergraduate nursing students and their association with resilience and self-efficacy.

AIM: This study aimed to investigate the heterogeneity of academic resilience among nursing students using latent profile analysis and its associated influencing factors. BACKGROUND: Nursing students experience higher levels of stress compared to their peers in other professions, and the cultivation of academic resilience plays a pivotal role in their ability to effectively cope with this stress. Academic resilience not only facilitates success in the face of academic adversity but also contributes to the promotion of mental well-being among nursing students. However, the current research on the academic resilience of nursing students has predominantly focused on a scale-centered total score approach, disregarding individual variability, and hindering the development to inform personalized interventions for enhancing academic resilience. DESIGN: A cross-sectional study. METHODS: A convenience sampling method was used to collect a total of 644 nursing students from two medical schools in Guangzhou City. The participants were recruited through an online survey conducted from January to March 2023. The questionnaires consisted of a general information form, the Chinese version of the Academic Resilience Scale-30 (C-ARS-30), the 10-item Connor Davidson Resilience Scale (CD-RISC-10), and the General Self-Efficacy Scale (GSES). Latent profile analysis was used to identify distinct categories of academic resilience among nursing students, and influencing factors were examined through ordinal logistic regression analysis. RESULTS: The academic resilience levels of nursing students can be divided into three potential categories: 'low academic resilience' (13.0%), 'moderate academic resilience' (70.0%), and 'high academic resilience' (17.0%). Level of grade, GPA, self-reported physical health level, resilience and self-efficacy were significantly influenced the different categories of academic resilience of nursing students (P<0.05). CONCLUSIONS: The majority of undergraduate nursing students were placed in the moderate academic resilience group, however, educational institutions should pay special attention to nursing students demonstrating low levels. Regular assessments of academic resilience are recommended, and personalized interventions should be tailored to address specific academic resilience characteristics across different grades of nursing students. Strategies aimed at enhancing academic resilience among nursing students may include improvements in GPA performance, attention to physical health, and the reinforcement of resilience and self-efficacy.

Organic acid and sugar components accumulation and flavor associated metabolites dynamic changes in yellow- and white-fleshed seedless loquats (Eriobotrya japonica).

Triploid loquats are divided into yellow- and white-fleshed cultivars. To better understand taste variations in triploid loquat fruits, we used a UPLC-ESI-QTRAP-MS/MS-based widely targeted metabolomic analysis to examine the metabolic composition of two different color fleshed triploid loquats with a sample size of 54 and external validation method within a confidence level of P＜0.05. We identified key flavor-related differentially accumulated metabolites using the variable importance in projection (VIP) value (VIP ≥ 1.0) and fold change ≥ 2 or ≤ 0.5. Furthermore, the results of the HPLC analysis showed that white-fleshed loquats had a low malic acid content. We also performed the UPLC-MS/MS system to investigate the carotenoids contents and lipidome in four triploid cultivars. In the fruits of white-fleshed varieties, the carotenoids contents were significantly downregulated, but the contents of most glycerolphospholipids were increased. Our results reveal the metabolomic changes between the yellow- and white-fleshed cultivars.

Quality of life and its association with predictors in lung transplant recipients: a latent profile analysis.

Backgrounds: Improving quality of life (QOL) is one of the main aims of lung transplantation (LTx). There is a need to identify those who have poor quality of life early. However, research addressing inter individual quality of life variability among them is lacking. This study aims to identify group patterns in quality of life among lung transplant recipients and examine the predictors associated with quality of life subgroups. Methods: In total, 173 lung transplant recipients were recruited from one hospital in Guangdong Province between September 2022 and August 2023. They were assessed using the Lung Transplant Quality of Life scale (LT-QOL), Mindful Attention Awareness Scale (MAAS), Life Orientation Test-Revised scale (LOT-R), and Positive and Negative Affect Scale (PANAS). Latent profile analysis was used to identify QOL subtypes, and logistic regression analysis was used to examine the associations between latent profiles and sociodemographic and psychosocial characteristics. Results: Two distinct QOL profiles were identified: "low HRQOL" profile [N = 53 (30.94%)] and "high HRQOL" profile [N = 120 (69.06%)]. Single lung transplant recipients, and patients who reported post-transplant infection, high levels of negative emotion or low levels of mindfulness and optimism were significantly correlated with the low QOL subgroup. Conclusion: Using the domains of the LT-QOL scale, two profiles were identified among the lung transplant recipients. Our findings highlighted that targeted intervention should be developed based on the characteristics of each latent class, and timely attention must be paid to patients who have undergone single lung transplantation, have had a hospital readmission due to infection, exhibit low levels of optimism, low levels of mindfulness or high negative emotions.

Therapeutic evaluation of rosuvastatin on lipids and endothelial cell functionalities in coronary artery lesions coinciding with hyperlipidemia.

OBJECTIVE: To analyze the changes of blood lipids and endothelial cell function in patients with coronary heart disease complicated with hyperlipidemia after treatment with rosuvastatin. METHODS: A total of 120 patients with coronary heart disease and hyperlipidemia diagnosed from December 2020 to December 2021 were retrospectively included. Depending on the differences of their treatment strategies, patients were divided into the study group (60 patients were treated with rosuvastatin using the conventional treatment) and the control group (60 patients were treated with the conventional treatment). Dynamic blood lipid level monitoring was performed on the two groups of patients. The changes of cardiac function and hemorheology indexes were evaluated before and after the treatment. Analyze the difference of vascular endothelial function index between the two groups before and after the treatment. Count the occurrence of adverse reactions during the intervention period of the two groups. RESULTS: Before the treatment, there was no significant difference between the two groups in total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL-C), left ventricular ejection fraction (LVEF), left ventricular end-systolic diameter (LVDS), left ventricular end-diastolic diameter (LVEDD), fibrinogen content, plasma viscosity, nitric oxide (NO), and endothelin (ET) levels (P>0.05). At 60 days of treatment, there was no significant difference between the two groups in TC, TG, LDL-C, LVDS, and LVEDD. The fibrinogen content, plasma viscosity, and ET level were lower than those in the control group (P<0.05). The HDL-C, LVEF, and NO levels were higher than those in the control group (P<0.05). There was no significant difference in the total incidence of adverse reactions between the two groups (8.33% vs 13.33%) (P>0.05). CONCLUSION: Resuvastatin can reduce the level of blood lipids in patients with coronary heart disease and hyperlipidemia and improve the hemorheology indexes and cardiac function of patients. Its mechanism may be related to the regulation of vascular endothelial cell function in patients with coronary heart disease.

Dose study of rosuvastatin calcium in the treatment of coronary heart disease and hyperlipidemia.

OBJECTIVE: To study the clinical efficacy of different doses of rosuvastatin to treat elderly patients with senile coronary heart disease and hyperlipidemia. METHODS: By means of retrospective analysis, 150 elderly patients with coronary heart disease and hyperlipidemia who were treated in Zhangjiakou First Hospital from January 2020 to December 2020 were selected as the study subjects. They were divided into three groups (50 patients in each group) according to the different treatment methods. All patients were given routine treatment for coronary heart disease and hyperlipidemia. At the same time, group A got 5 mg of rosuvastatin calcium per day, group B got 10 mg and group C got C, 20 mg. After 4 months of continuous treatment, changes of blood lipid level, inflammatory factors, and cardiac function in the three groups were compared before and after treatment. Finally, the incidence of adverse reactions in the three groups was statistically compared. RESULTS: After 4 months of treatment, the levels of TC, LDL, and TG in group B were significantly lower than those of group A, and the levels of HDL were significantly higher than those in group A (P<0.05). There was no significant difference of the above indicators between groups B and C after 4 months of treatment (P>0.05). Using 2 months, 3 months, and 4 months of therapy as time points, the blood lipid levels of the B and C groups was lower than in group A (P<0.05); Serum hs-CRP and TNF of patients in group B and group C after 4 months of treatment were significantly lower than those of group A (P<0.05); The LVEF comparison between groups showed that C was higher than A (P<0.05); The occurrence rate between adverse reactions during the 4 months of medication did not have statistical significance (P>0.05). CONCLUSION: Rosuvastatin calcium canimprove the clinical symptoms of elderly patients with coronary heart disease complicated by hyperlipidemia, and can improve the blood lipid level, cardiac function and the level of inflammatory factors in the body, but the clinical effect is not significantly improved by increasing the application dose. This suggests that the daily application dose should be 10 mg.

Chinese cross-cultural adaptation and validation of the Well-being Numerical Rating Scales.

Introduction: Well-being is a multi-domain concept that involves measuring physical, psychological, social, and spiritual domains. However, there are currently few multi-domain and comprehensive well-being instruments available. In addition, measures that do exist customarily contain a vast number of items that may lead to boredom or fatigue in participants. The Well-being Numerical Rating Scales (WB-NRSs) offer a concise, multi-domain well-being scale. This study aimed to perform the translation, adaptation, and validation of the Chinese version of WB-NRSs (WBNRSs-CV). Methods: A total of 639 clinical participants and 542 community participants completed the WB-NRSs-CV, the Single-item Self-report Subjective Well-being Scale (SISRSWBS), the World Health Organization Five-item Well-Being Index (WHO-5), the 10-item Perceived Stress Scale (PSS-10), and the Kessler Psychological Distress Scale (K10). Results: High internal consistency and test-retest reliability were obtained for both samples. Additionally, WB-NRSs-CV was positively associated with SISRSWBS and WHO-5 and negatively associated with PSS-10 and K10. In the item response theory analysis, the model fit was adequate with the discrimination parameters ranging from 2.73 to 3.56. The diffculty parameters ranged from -3.40 to 1.71 and were evenly spaced along the trait, attesting to the appropriateness of the response categories. The invariance tests demonstrated that there was no difference in WB-NRSs-CV across groups by gender or age. Discussion: The WB-NRSs-CV was translated appropriately and cross-culturally adapted in China. It can be used as a rapid and relevant instrument to assess well-being in both clinical and non-clinical settings, with its utility for well-being measurement and management among the Chinese people.

Circular RNA intraflagellar transport 80 facilitates endometrial cancer progression through modulating miR-545-3p/FAM98A signaling.

OBJECTIVE: Endometrial cancer (ECa) is a common gynecological malignancy. Circular RNAs (circRNAs) have been identified as key regulators of human tumorigenesis and development. Herein, we explored the role and mechanism of circular RNA intraflagellar transport 80 (circ-IFT80, also called circ_0067835) in ECa. METHODS: Circ-IFT80, microRNA-545-3p (miR-545-3p), and family with sequence similarity 98 member A (FAM98A) were quantified by quantitative real-time polymerase chain reaction or Western blot. The biological characteristics of ECa cells were evaluated via Cell Counting Kit-8, 5-ethynyl-2'-deoxyuridine, transwell, tube formation and flow cytometry assays. Dual-luciferase reporter assay or RNA pull-down assay was employed to verify the binding relationship between miR-545-3p and circ-IFT80 or FAM98A. Xenograft assays were conducted to analyze the effect of circ-IFT80 in vivo. RESULTS: Circ-IFT80 and FAM98A were up-regulated, and miR-545-3p was down-regulated in ECa tissues and cells. Knockdown of circ-IFT80 blocked proliferation, migration, invasion and angiogenesis and promoted apoptosis in ECa cells. Moreover, circ-IFT80 harbored a binding site for miR-545-3p, and the effects of circ-IFT80 were mediated by miR-545-3p. FAM98A was a direct target of miR-545-3p, and miR-545-3p hindered ECa cell progression via targeting FAM98A. Circ-IFT80 induced FAM98A expression through miR-545-3p. Furthermore, silence of circ-IFT80 suppressed tumor growth in vivo. CONCLUSION: Circ-IFT80 may promote the malignant progression of ECa cells at least in part by modulating miR-545-3p/FAM98A axis, providing a potential therapeutic target for ECa.

Identification and Analysis of Long Non-Coding RNAs Related to UV-B-Induced Anthocyanin Biosynthesis During Blood-Fleshed Peach (Prunus persica) Ripening.

Blood flesh is a key fruit trait in peaches (Prunus persica) and can be attributed to the accumulation of anthocyanins. The roles of long non-coding RNAs (lncRNAs) have been highlighted by multiple studies in regulating fruit ripening, anthocyanin accumulation, and abiotic stress responses in many flowering plants. Such regulatory functions of lncRNAs in Prunus persica, nonetheless, have not been reported. In this research, we sequenced and analyzed the complete transcriptome of C3-20 (a blood-fleshed peach) fruit at four developmental stages. Analyses of the correlated genes and differentially expressed lncRNA target genes helped to forecast lncRNAs' possible functions. The RNA-seq data were generated using high-throughput sequencing. In total, 17,456 putative lncRNAs, including 4,800 intergenic lncRNAs, 2,199 antisense lncRNAs, and 10,439 intronic lncRNAs were discovered, of which 4,871 differentially expressed lncRNAs (DE-lncRNAs) were annotated in the fruit developmental processes. The target genes of these DE-lncRNAs and their regulatory relationship identifying 21,795 cis-regulated and 18,271 trans-regulated targets of the DE-lncRNAs were in a similar way predicted by us. The enriched GO terms for the target genes included anthocyanin biosynthesis. Flavonoid biosynthesis and plant hormone signal transduction were also included in the enriched KEGG pathways. Co-expression network construction demonstrated that the highly expressed genes might co-regulate multiple other genes associated with auxin signal transduction and take effect in equal pathways. We discovered that lncRNAs, including LNC_000987, LNC_000693, LNC_001323, LNC_003610, LNC_001263, and LNC_003380, correlated with fruit that ripened and could take part in ethylene biosynthesis and metabolism and the ABA signaling pathway. Several essential transcription factors, such as ERFs, WRKY70, NAC56, and NAC72, may in a similar way regulate fruit ripening. Three DE-lncRNAs, XLOC_011933, XLOC_001865, and XLOC_042291, are involved in UV-B-induced anthocyanin biosynthesis and positively regulating UVR8 and COP10, were identified and characterized. Our discovery and characterization of XLOC_011933, XLOC_001865, and XLOC_042291 provide a more precise understanding and preliminarily establishes a theoretical framework for UV-B-induced flesh anthocyanin biosynthesis. This phenomenon might encourage more in-depth investigations to study the molecular mechanisms underlying peach flesh coloring.
