Objective:To explore the application effect of the attention and interpretation therapy based on Swanson′s caring theory in adolescents with epilepsy, aiming to reduce negative emotions and improve self-management levels in children.Methods:This study was a quasi-experimental research. A convenience sampling method was used to select 78 adolescents with epilepsy who were admitted to the Department of Neurology, the Affiliated Children′s Hospital of Xiangya School of Medicine, Central South University (Hunan Children′s Hospital) from March 1 to August 31, 2023. The participants were assigned into two groups, the control group ( n=39) and the intervention group ( n=39), using a random number table. The control group received standard anti-epileptic treatment and routine nursing care, while the intervention group received the same treatment and care with the addition of a caring team providing attention and interpretation therapy based on Swanson′s caring theory. Assessments were made at three time points: before the intervention, 4 weeks after the intervention, and 12 weeks after the intervention. The Depression-Anxiety-Stress Scale (DASS-21), Epilepsy Self-Management Scale (ESMS), and Pediaric Quality of Life Inventory Measurement Methods (PedsQL TM4.0) were used to assess the participants′ scores. Results:In the control group, 23 were male and 16 were female, with aged of (13.49 ± 1.43) years. In the intervention group, 24 were male and 15 were female, with aged of (13.51 ± 1.45) years. After 4 weeks of intervention, the scores of depression, anxiety, and stress on the DASS-21 for the intervention group were (9.32 ± 2.04), (6.79 ± 2.44), and (13.63 ± 2.67), respectively, which were lower than those of the control group: (10.43 ± 2.27), (8.43 ± 2.75) and (16.05 ± 3.32); the scores of ESMS and PedsQL TM4.0 in the intervention group were (66.66 ± 10.87) and (73.63 ± 9.85), respectively, which were higher than those of the control group: (60.70 ± 10.24) and (67.27 ± 12.33), the differences were statistically significant ( t values were -2.47 to 3.49, all P<0.05). After 12 weeks of intervention, the scores on the DASS-21 for the intervention group were (5.47 ± 1.66), (3.37 ± 1.68) and (8.42 ± 2.24) for depression, anxiety and stress, respectively, which were lower than those of the control group: (8.03 ± 1.98), (6.06 ± 2.64) and (11.28 ± 3.21) ;the scores for ESMS and PedsQL TM4.0 in the intervention group were (74.66 ± 9.15) and (85.24 ± 7.00), respectively, which were higher than those of the control group: (65.36 ± 10.86) and (75.67 ± 11.39), the differences were statistically significant ( t values were -4.33 to 6.03, all P<0.05). Additionally, there were statistically significant differences in the DASS-21 depression, anxiety, and stress scores, ESMS, and PedsQL TM4.0 scores across the different time points ( F values ranged from 4.65 to 1 134.03, all P<0.05). Conclusions:Attention and interpretation therapy based on Swanson′s caring theory can effectively reduce negative emotions in adolescents with epilepsy, improve their self-management skills, and further enhance their quality of life.

Objective:To evaluate the effects of cognitive behavior therapy(CBT)combined with attention training technique(ATT)on auditory hallucinations of schizophrenia.Methods:Sixty schizophrenia patients with au-ditory hallucinations were recruited according to the criteria of International Classification of Diseases,tenth Edition(ICD-10).They were randomly divided into the CBT group(30 cases,26 cases completed)and the CBT+ATT group(30 cases,25 cases completed).The CBT group received only 4 weeks of cognitive behavioral intervention for auditory hallucinations,and the CBT+ATT group received 6 weeks of attention training technology intervention based on cognitive behavioral intervention.At baseline and after 12 weeks,the Psychotic Symptom Rating Scales-Auditory Hallucinations(PSYRATS-AH)and Scale of Social function in Psychosis Inpatients(SSPI)were used to evaluate the auditory hallucinations symptoms and social functioning of the two groups,and the Attentional Control Scale(ACS)was used to evaluate patients'attentional control ability of the CBT+ATT group.Results:After 12 weeks,the differences(post intervention score-baseline score)of PSYRATS-AH total scores[(-6.8±2.2)vs.(-4.2±1.5)],auditory hallucinations'frequency,duration,number of distresses,control of voices were lower in the CBT+ATT group than in the CBT group(Ps＜0.05),and the differences of the SSPI total scores[(13.9± 2.9)vs.(11.6±4.2)]and scores of Factor I and Factor Ⅲ were higher in the CBT+ATT group than in the CBT group(Ps＜0.05).Conclusion:This study shows cognitive behavioral therapy combined with attention training technique could improve auditory hallucinations and social function more effectively in patients with schizophrenia.

Objective To study the effect of changes in estradiol(E2)levels on the reproductive outcomes of pa-tients with polycystic ovary syndrome(PCOS)undergoing controlled ovarian stimulation(COS)with gonadotropin-releasing hormone antagonist(GnRH-ant)protocol.Methods A retrospective study was conducted involving 338 patients with polycystic ovary syndrome(PCOS)infertility who underwent GnRH-ant protocol for controlled ovarian hyperstimulation followed by in vitro fertilization(IVF)or intracytoplasmic sperm injection(ICSI),and subse-quently underwent their first frozen-thawed embryo transfer(FET).The clinical data of these patients were ana-lyzed.Patients were grouped based on the changes in serum E2 levels on the first and fourth day of GnRH-ant ad-ministration(blood samples collected before GnRH-ant injection):the E2 elevation group(Group A,E2 value in-creased more than 30％,165 cases),the E2 stable group(Group B,E2 rate of change was within-30％～30％,162 cases),and the E2 decline group(E2 value declined more than 30％,11 cases,not included in statistical a-nalysis due to small sample size).The differences in demographic characteristics,ovulation induction outcomes,embryo outcomes and clinical pregnancy-related indicators were analyzed between Groups A and B.Results There were no statistically significant differences in basic information such as age,duration of infertility,body mass index(BMI),basal endocrine levels,and anti-Müllerian hormone(AMH)levels between groups A and B.Regarding embryo characteristics,there were no statistically significant differences in fertilization method and number of trans-ferred embryos between groups A and B.However,group A had a higher total number of retrieved oocytes,normal fertilization rate,number of high-quality embryos,and rate of high-quality embryos compared to group B,with sta-tistically significant differences(P＜0.05).In terms of clinical pregnancy outcomes,there were no statistically significant differences in the incidence of severe ovarian hyperstimulation syndrome(OHSS)between groups A and B.However,group A had higher rates of clinical pregnancy,implantation,and live birth compared to group B,with statistically significant differences.Group A also had a lower rate of early miscarriage compared to group B,with statistically significant differences.Conclusion Choosing the GnRH-ant protocol for IVF/ICSI-FET in PCOS patients,if the blood E2 level increases by more than 30％after 4 days of adding the antagonist(blood sample col-lected before administering GnRH-ant),the clinical pregnancy outcome will be better.

Objective To research the effectiveness of deep learning techniques in intelligently diagnosing dental caries and periapical periodontitis and to explore the preliminary application value of deep learning in the diagnosis of oral diseases.Methods A dataset containing 2 298 periapical films,including healthy teeth,dental caries,and peri-apical periodontitis,was used for the study.The dataset was randomly divided into 1 573 training images,233 valida-tion images,and 492 test images.By comparing various neural network models,the MobileNetV3 network model with better performance was selected for dental disease diagnosis,and the model was optimized by tuning the network hyper-parameters.The accuracy,precision,recall,and F1 score were used to evaluate the model's ability to recognize dental caries and periapical periodontitis.Class activation map was used to visualization analyze the performance of the net-work model.Results The algorithm achieved a relatively ideal intelligent diagnostic effect with precision,recall,and accuracy of 99.42%,99.73%,and 99.60%,respectively,and the F1 score was 99.57%for classifying healthy teeth,den-tal caries,and periapical periodontitis.The visualization of the class activation maps also showed that the network model can accurately extract features of dental diseases.Conclusion The tooth lesion detection algorithm based on the Mo-bileNetV3 network model can eliminate interference from image quality and human factors and has high diagnostic accu-racy,which can meet the needs of dental medicine teaching and clinical applications.

Objective: To explore the changes in ribosomal DNA copy number in peripheral blood among patients with pneumoconiosis and its influencing factors, so as to provide insights into prevention and treatment of pneumoconiosis. Methods: Eighty-eight patients with pneumoconiosis who visited a designated hospital and 71 community residents with no history of pneumoconiosis or dust exposure were selected as the pneumoconiosis group and control group, and age, smoking history, drinking history and cumulative years of exposure to dust were collected through questionnaire surveys. The copy number of 45S rDNA and 5S rDNA was detected using real-time fluorescence quantitative PCR, and the differences between the two groups were compared. Factors affecting the copy number of 45S rDNA and 5S rDNA were identified by a multiple linear regression model. Results: The pneumoconiosis group had a median age of 56.00 (interquartile range, 15.25) and a mean cumulative dust exposure duration of (12.40±8.08) years, with 56.82% smoking and 62.50% drinking. The control group had a median age of 64.00 (interquartile range, 37.00) years, with 32.39% smoking and 26.76% drinking. The median copy number of 45S rDNA in the pneumoconiosis group was 1.29 (interquartile range, 0.59), which was lower than 2.10 (interquartile range, 1.88) in the control group; the median copy number of 5S rDNA in the pneumoconiosis group was 5.33 (interquartile range, 0.85), which was higher than 4.66 (1.34) in the control group (both P<0.05). Multiple linear regression analysis identified age (β=-0.034) and pneumoconiosis (β=-1.595) as factors affecting 45S rDNA copy number, age (β=-0.013) as a factor affecting 5S rDNA copy number, and age (β=0.018) as a factor affecting 5S rDNA copy number in the pneumoconiosis group (all P<0.05). Conclusions Compared with community residents with no history of pneumoconiosis or dust exposure, the copy number of 45S rDNA in peripheral blood among patients with pneumoconiosis is reduced and the copy number of 5S rDNA is increased.

Objective:To construct an index system for including ideological and political education elements and cases in the Health Assessment course, and to provide a reference for the evaluation of ideological and political teaching of the Health Assessment course.Methods:By using literature analysis, the nominal group method, and the Delphi expert consultation method, we determined indicators for ideological and political elements and case inclusion criteria for the undergraduate nursing course Health Assessment. The analytic hierarchy method was applied to quantify the items and determine the final weights of the indicators at each level.Results:The response rates of two rounds of expert consultation were both 100%. The authority coefficient of the experts was 0.880. For the second-round consultation on the system of ideological and political elements, the coefficient of variation was 0.078, and the Kendall's coefficient of concordance was 0.334. For the second-round consultation on the inclusion criteria for ideological and political cases, the coefficient of variation was 0.075, and the Kendall's coefficient of concordance was 0.312. Finally, we determined 6 first-level indicators and 30 second-level indicators for the ideological and political elements of the Health Assessment course, and 9 indicators for the inclusion of ideological and political cases for the Health Assessment course.Conclusions:The established index system for the ideological and political elements and cases of the Health Assessment course for nursing undergraduates is reasonable, scientific, and reliable, which can provide a reference for subsequent construction of the ideological and political teaching system for the Health Assessment course.

Purpose To investigate the conventional ultrasound and contrast-enhanced ultrasound features of epiploic appendagitis (EA). Materials and Methods A retrospective study was performed on 23 patients who were diagnosed with EA in the 907th Hospital of Chinese People's Liberation Army Joint Logistic Support Force from May 2016 to May 2023. The conventional and contrast-enhanced ultrasound findings were analyzed,and the subsequent evolution of ultrasound findings were followed up. Results All 23 patients presented with a solitary mass adjacent to the colon or cecum,with eleven masses being oval,eight being elliptical and four irregular in shape. The margin of the mass was clear in 15 cases,with 12 cases showing a linear hypoechoic rim around the mass. All 23 masses appeared as solid hyperechoic lesions,with two cases showing internal inhomogeneous echoes and linear hypoechoic areas,three cases showing mild thickening of the adjacent intestinal wall and 19 cases showing adhesion to the anterior abdominal wall and fixed in position. No obvious blood flow signals were detected inside the masses in all 23 cases,while only five cases showing slight blood flow signals around the mass periphery. Contrast-enhanced ultrasound demonstrated that the central part of the mass did not enhance,while the edge of the mass showed a ring-shaped hyperenhancement with a thickness of approximately 0.20-1.50 cm in ten patients. Follow-up ultrasound examinations were performed in 12 patients,and the results showed that seven patients had complete disappearance of the initial mass,with one patient found to have a loose body in the rectouterine pouch,and the volume of the mass in the remaining five patients showed varying degrees of reduction during the follow-up period. Conclusion The characteristics of contrast-enhanced ultrasound in EA include a central necrotic area without enhancement,showing a ring-shaped enhancement at the edge. Contrast-enhanced ultrasound is a highly effective imaging modality that can provide strong evidence for the clinical diagnosis of EA by visualizing the size and extent of the infarcted epiploic appendage.
