Objective:To understand the current status and analyze the factors of demoralization of patients with chronic heart failure (CHF), providing references for targeted psychological interventions of nursing staff.Methods:Using the cross-sectional survey method, from August 2022 to January 2023, 282 CHF patients who were followed up in the Cardiovascular Department of the First Affiliated Hospital of Zhengzhou University were selected as the study subjects. They were investigated using the General Information Questionnaire, Demoralization Scale Revised Mandarin Version, Brief Illness Perception Questionnaire (BIPQ), Fear of Progression Questionnaire-Short Form (FoP-Q-SF), and the factors influencing the demoralization of CHF patients were analyzed using univariate analysis and multiple linear regression.Results:Among 282 cases, male 172 cases, female 110 cases, aged (62.29±10.05) years old. The Demoralization Scale Revised Mandarin Version′s score of CHF patients was (30.30 ± 10.37) points; the score of BIPQ was (42.18 ± 13.94) points; the score of FoP-Q-SF was (35.41 ± 7.29)points, which were at high level. The results of multiple linear regression analysis showed that patient disease duration, disease stages, New York heart association cardiac function classification, the score of BIPQ, and the score of FoP-Q-SF were factors influencing the demoralization of CHF patients ( t values were 3.08 to 12.50, all P<0.05). Conclusions:There is an urgent need to focus on the current status of the demoralization of CHF patients. It is necessary to develop a systematic and effective intervention strategy for demoralization, to take into account patient disease duration, disease stages, illness perception, and fear of progression in a comprehensive manner.

Objective:To explore the mediating role of disease progression′s fear and positive affect in the relationship between disease perception and demoralization in patients with chronic heart failure. It provided a theoretical basis for targeted interventions for healthcare workers.Methods:From October 2022 to March 2023, 320 patients with chronic heart failure in the First Affiliated Hospital of Zhengzhou University were selected as the research objects by convenience sampling. The General Information Questionnaire, Demoralization Scale Redacted Mandarin Version, Brief Illness Perception Questionnaire, Fear of Progression Questionnaire-Short Form, Positive and Negative Affect Schedule (Positive Affect Schedule) were used to conduct the questionnaire survey exploring the mediating effects of fear of disease progression and positive emotions between disease perception and disorientation by construction structural equation model.Results:There were 268 valid questionnaires. Of the 268 patients, 168 were male and 100 were female, 3.36% (9/268) were ≤40 years old, 55.22% (148/268) were 41-65 years old, and 41.42% (111/268) were >65 years old. Correlation analysis showed that disease perception was positively correlated with disease progression ′s fear, and every dimension of demoralization ( r values were 0.300-0.586, all P<0.01), and negatively correlated with positive affect ( r=-0.374, P<0.01); disease progression′s fear was negatively correlated with positive affect ( r=-0.318, P<0.01), and positively correlated with every dimension of demoralization ( r values were 0.339-0.464, all P<0.01); positive affect was negatively correlated with every dimension of demoralization ( r values were -0.430--0.334, all P<0.01). Structural equation model analysis showed that the direct effect of disease perception on demoralization was significant ( β=0.407, P<0.01), and both mediating effects of disease progression ′s fear and positive affect between disease perception and demoralization in patients with chronic heart failure were significant ( β=0.074, 0.079, both P<0.01). The chain mediating effect of disease progression ′s fear and positive effect was also significant ( β=0.019, P<0.01). Conclusions:Disease perception could directly predict the demoralization of patients with chronic heart failure and indirectly predict the demoralization of patients with chronic heart failure through the mediating effect of disease progression ′s fear, positive affect, and the chain mediating effect of disease progression ′s fear and positive affect.

Objective:To analyze the research hotspots and trends of swallowing disorders in patients with head and neck tumors both domestically and internationally, to provide reference for future research directions.Methods:Using the China National Knowledge Infrastructure and Web of Science core collection databases as data sources, research literature related to swallowing disorders in head and neck tumor patients published from January 1, 2013, to December 31, 2022, was retrieved. A knowledge graph was drawn using Cite Space 6.2 R3 software, and the graph was interpreted and analyzed from the aspects of publication volume, publication country, and institution, high-frequency keyword co-occurrence and clustering, and emergent words.Results:A total of 427 English literature were included. The overall number of publications is on the rise. The countries with a high volume of collaborative publications were the United States, Australia, the Netherlands, and the United Kingdom. The top three institutions in terms of publication volume were the University of Queensland in Australia, the University of Newcastle in the UK, and the Amsterdam Institute in the Netherlands. A total of 10 cluster clusters and 25 prominent keywords were obtained. The hot topics of research and analysis were "swallowing dysfunction" "associated complications" and "long-term effects", with the forefront being "radiation-induced dry mouth syndrome".Conclusions:Compared to foreign countries, China currently has a relatively small number of publications, loose cooperation between research authors and institutions, and a need for more diverse disciplines and research methods. Focusing on hot topics and cutting-edge content, exploring the mechanism of swallowing disorders in head and neck tumors, implementing targeted interventions, strengthening health education, predicting postoperative dangerous complications, constructing feasible nursing plans, and improving the quality of life of patients will become the development trend of future research.

Objective:To explore the therapeutic effect of low-intensity extracorporeal shock wave (Li-ESW) in model rats with chronic prostatitis and its optimal parameters.Methods:From April to August 2019, 90 healthy male SD rats aged 8 weeks were randomly divided into control group (group C, n=15), model group (group M, n=15) and shock wave treatment group (group T, n=60), which were treated with Li-ESW after being modeled successfully. The rats in group T were supine and treated with focused Li-ESW, and the probe was placed above the anatomical position of the prostate. Treatment scheme was 3 Hz of frequency, 500 pulses, and once a week for 4 weeks. Group T was divided into group T1(0.09 mJ/mm 2), T2(0.20 mJ/mm 2), T3(0.30 mJ/mm 2) and T4(0.40 mJ/mm 2) according to energy flux density, with 15 rats in each group. Before the establishment of the model, the rats in each group were tested with von Frey fiber of 2 g, 4 g and 6 g at the scrotum respectively, and the positive reaction was recorded. There was no significant difference between the three groups ( P>0.05). After one week, the rat model with CP was established by injecting 3% carrageenan into the bilateral lobes of the prostate under anesthesia. And one week after the modeling was completed, the rats in each group underwent von Frey test again to measure pain and evaluate the modeling effects. Group T was then treated once a week for a 4-week period. During the treatment, von Frey test was performed before each treatment to evaluate the treatment effect of the previous week. After the von Frey test for one, two and four weeks of treatment, 5 rats were sacrificed in each group, and the bilateral lobes of the prostate were dissected under aseptic conditions for paraffin inclusion and HE staining. Result:The positive reaction in group M and each group T was significantly more than those in group C ( P<0.001) one week after the modeling was completed, and there was no significant difference between group M and group T. The number of positive reactions in group T2 was lower than that in group M at each time point after treatment ( P<0.05), and it is also less in group T1, T3 and T4 were than that in group M after 3 weeks, 3 and 4 weeks and 2 weeks respectively( P<0.05). In group T2, the number of positive reactions began to decrease after 1 week of treatment, and reached the lowest after 4 weeks, with significant difference in pain measurement results at different time points ( P<0.05). The results of pathological examination showed that there were more inflammatory cells in prostatic stroma and disordered arrangement of epithelial cells in group M than that in group C. The pathological scores of group M, T1, T2, T3 and T4 were 8, 7, 4, 6, 9 after 1 week treatment, 8, 5, 3, 4, 7 points after 2 weeks treatment, and 7, 3, 2, 4, 7 points after 4 weeks treatment, respectively. Conclusions:Low-intensity extracorporeal shock wave treatment had a significant effect on the improvement of symptoms in model rats with chronic prostatitis. Under the scheme of frequency 3 Hz, 500 pulses, once a week for 4 weeks, the optimal parameters is 0.20 mJ/mm 2.

Objective:To investigate the factors related to child care environment and the association between child care environment and children′s early development.Methods:Using stratified cluster random sampling, a total of 22 509 children newly enrolled to kindergarten from 187 kindergartens of 16 districts in Shanghai in 2017 were enrolled. A survey was conducted by parent-reported questionnaire. The index of child care environment (ICCE) and the early human capacity index were used to evaluate family child care environment and children′s early development respectively. The sample was divided into four groups based on the ICCE score: the lowest family childcare environment (ICCE≤10 scores), lower middle (ICCE=11 scores), upper middle (ICCE=12 scores), and the highest (ICCE=13 scores). The linear regression model and Logistic regression model were used to analyze the factors related to child care environment and the association between child care environment and children′s early development respectively.Results:A total of 22 067 children aged (44±7) months, including 11 425 boys (51.8%) and 10 642 girls (48.2%), participated in this study. The multnomial linear regression revealed girls, higher maternal education, higher household annual income, single-child, non-divorced parents, and early breastfeeding experience were protective factors of child care environment for children newly enrolled to kindergarten ( β=0.064, 0.238, 0.119, 0.096, 0.113, and 0.032; 95% confidence interval ( CI): 0.020-0.108, 0.175-0.302, 0.058-0.180, 0.046-0.146, -0.012-0.242, and -0.051-0.116; all P<0.01). The multinomial Logistic regression revealed compared with the highest child care environment group, the odds ratio of children′s early development risks in upper midclle, lower middle, and the lowest child care environment groups were 1.543 (95% CI: 1.373-1.735, P<0.01), 2.537 (95% CI: 2.254-2.856, P<0.01), and 4.198 (95% CI: 3.757-4.690, P<0.01), respectively. Conclusions:The child care environment is not only significantly related to family structure and socioeconomic status, but also to early breastfeeding experience. The child care environment plays an important role in promoting childhood early development.

BACKGROUNDEpstein-Barr virus (EBV) infection is one of the most important factors of nasopharyngeal carcinoma (NPC) endemic areas. Transcription of EBV-encoded non-polyadenylated RNAs (EBERs) are presented in most of NPC tumors. Exploring EBERs as a prognostic marker for NPC might further be informative about the biology and the progression of the disease. The aim of this study was to analyze the role of EBV latency in the clinical management of nasopharyngeal carcinoma (NPC), by detecting EBERs.

METHODSRNA in situ hybridization (ISH) for detecting EBERs was carried out on 908 NPC tumor tissues. Overall survival (OS) curves were analyzed with the Kaplan-Meier method and the Cox proportional-hazards regression models.

RESULTSThe median follow-up time was 70 months (1-120 months). Eight hundred and sixteen (89.9%) from a total of 908 consecutive NPC cases were found to be EBV-EBER positive. EBER-ISH staining revealed nuclear localization in NPC cells. In the Kaplan-Meier analysis for OS, high EBER expression levels in NPC patients were statistically significant positive prognostic factors for survival (log-rank, P = 0.022), especially in adults aged 17-40 years (P = 0.023) and in those with advanced stage disease (log-rank, P = 0.002). Cox proportional-hazards regression model analysis showed that the EBER expression level was an independent risk factor for OS (hazard ratio 0.724, P = 0.005).

CONCLUSIONSEBERs were frequently detected in NPC tumor tissues, and high-level EBER expression correlated with good prognosis in NPC patients, especially in adult patients and in those with advanced stage disease. EBER may serve as a potential prognostic predictor in NPC.
