AIM: To provide references for the non-clinical evaluation of therapeutic targets or drugs for retinoblastoma, fluorescently labeled Y79 cells are injected into the vitreous body of BALB/c-nu mice to establish a retinoblastoma model, and the Melphalan treatment group is used as a positive control, which is verified by fluorescence imaging technology.METHODS: BALB/c-nu mice were intravitreous injected with GFP transfected Y79 cells(1.0×107 cell/mL, 3 μL)to establish the model. On the 27th day, the mice were randomly divided into model control group and different doses of Melphalan groups(1, 3, 10 μg/eye groups)according to the fluorescence value of in vivo imaging, with vitreous body single administrated and ocular symptoms observed daily. Slit-lamp examination was performed at 12, 20, 29, 35, 42, 48, 55, 76, and 83 d after modeling. In vivo imaging was performed on 12, 20, 27, 41, 48, 55, 62, 69, 76, and 83 d. At the last treatment, the eyeball, brain and cerebellum tissues were removed for histopathological examination.RESULTS: From the sixth day of modeling, cloud-like substances could be seen in the eyes of the animals, and the cloud-like substances occupied the whole eyeball of the mice in the model control group at the later stage, accompanied by irregular growth of blood vessels. After 27 days of modeling, the fluorescence value was detected in all the animals, and the fluorescence value continued to increase with the extension of modeling time. The fluorescence value of the tumor reached the peak after 69-83 days of modeling. Histological examination showed severe proliferation of intraocular tumor cells in the model control group, and tumor cells were observed in the brain of 1 model animal. In the 10 μg/eye Melphalan group, the fluorescence value was significantly decreased at 17 d after administration. The fluorescence value of the 3 μg/eye Melphalan group was significantly inhibited at 59 d after administration. No tumor cells were found in the brain tissue of animals in all Melphalan groups.CONCLUSION: After vitreous injection of Y79/pCDH-LUC-copGFP cells in BALB/c-nu mice, significant ocular lesions and proliferation of tumor cells were observed in the eyes. Meanwhile, Melphalan intervention significantly inhibited tumor cells in a dose-dependent manner, indicating that the mouse model of retinoblastoma was successfully constructed.

Objective:To explore the status quo of supportive care needs of elderly patients with diabetes retinopathy after vitrectomy, and analyze its influencing factors, so as to provide reference for the formulation of nursing interventions.Methods:From May 2021 to May 2023, 274 diabetes retinopathy patients aged 65 years or older who underwent vitrectomy in the First Affiliated Hospital of Zhengzhou University were selected as the study subject by convenience sampling. The survey was conducted using the General Information Questionnaire, Supportive Care Needs Survey, Family partnership, Adaption, Growth, Affection, Resolve Index, and Hospital Anxiety and Depression Scale. Multiple linear regression was used to analyze the influencing factors of supportive care needs of elderly patients with diabetes retinopathy after vitrectomy.Results:The score of supportive care needs of elderly patients with diabetes retinopathy after vitrectomy was (95.95±6.96). Multiple linear regression analysis showed that educational level, self-care ability, family care, and anxiety and depression were the influencing factors of supportive care needs in patients, and the differences were statistically significant ( P<0.05) . Conclusions:The elderly patients with diabetes retinopathy after vitrectomy have high needs for supportive care, and most of the needs have not been met. Medical and nursing staff should fully evaluate the clinical characteristics of patients and develop personalized nursing strategies to meet their needs and improve their quality of life.

Objective:To explore the mediating effect of kinesiophobia on illness perception and exercise self-efficacy in patients with chronic heart failure (CHF) .Methods:From January to August 2023, convenience sampling was used to select CHF patients in the Department of Cardiovascular of Affiliated Hospital of Jining Medical University as the research subject. The patients were surveyed using the General Information Questionnaire, Tampa Scale for Kinesiophobia Heart (TSK-SV Heart) , Exercise Self Efficacy Scale, and the Brief Illness Perception Questionnaire (BIPQ) . Bootstrap method was used to examine the mediating effect of kinesiophobia on illness perception and exercise self-efficacy in CHF patients.Results:A total of 220 questionnaires were distributed, and 207 valid questionnaires were collected, with a valid response rate of 94.09% (207/220) . Among 207 CHF patients, the total TSK-SV Heart score, total Exercise Self Efficacy Scale score, and total BIPQ score were (43.36±10.50) , (37.00±15.84) , and (52.77±15.76) , respectively. Kinesiophobia partially mediated the relationship between illness perception and exercise self-efficacy in CHF patients, and the effect value was -0.251 ( P<0.01) , accounting for 42.76% of the total effect. Conclusions:Illness perception can directly affect the exercise self-efficacy of CHF patients, as well as indirectly affect their exercise self-efficacy through kinesiophobia. Medical and nursing staff should fully understand the patient's views on the disease, help patients have a correct understanding of the disease, and take certain intervention measures to help patients overcome their kinesiophobia, thereby improving their exercise self-efficacy.

Objective:To explore the latent profile types of capability-opportunity-motivation-behavior in stroke patients and analyze the influencing factors of different latent profiles.Methods:From January to October 2023, totally 596 stroke patients from the Neurology Department of five ClassⅢ Grade A hospitals in Henan Province were selected by stratified random sampling. The patients were surveyed using a general information questionnaire, the Stroke Prevention Knowledge Questionnaire (SPKQ), the Social Support Rating Scale (SSRS), the WHO's Quality of Life Questionnaire- Brief Version (WHOQOL-BREF), the Short Form Health Belief Model Scale (SF-HBMS), and the Health Promoting Lifestyle ProfileⅡ (HPLPⅡ). Latent profile analysis was used to classify the capability-opportunity-motivation-behavior characteristics of stroke patients, and multiple logistic regression was conducted to explore the influencing factors of different latent profiles.Results:Three latent profiles of capability-opportunity-motivation-behavior in stroke patients were identified, including low capability-opportunity-motivation-behavior with high health beliefs (32.4%, 193/596), moderate capability-opportunity-motivation-behavior with insufficient health beliefs (47.5%, 283/596), and high capability-opportunity-motivation-behavior with lack of social support (20.1%, 120/596). Multiple logistic regression analysis showed that educational level, smoking history, family history, body mass index, and Charlson Comorbidity Index score were influencing factors of different latent profiles ( P<0.05) . Conclusions:Stroke patients exhibit distinct classifications of capability-opportunity-motivation-behavior. Targeted interventions should be conducted based on the characteristics of each category to improve health behavior management outcomes in patients.

Objective:To explore the mediating effect of rumination between self-perceived burden (SPB) and stigma in stroke patients, so as to provide theoretical basis for the development of targeted nursing interventions in clinical practice.Methods:In September 2022, cluster sampling was used to select 1 126 stroke patients admitted to Department of Neurology of five ClassⅢ Grade A hospitals in Henan Province as subjects. General Information Questionnaire, Self-Perceived Burden Scale (SPBS), Stroke Stigma Scale (SSS), and Chinese Version of Event Related Rumination Inventory (C-ERRI) were used to investigate stroke patients. Pearson correlation analysis was used to explore the correlation between SPB, rumination, and stigma. AMOS 28.0 software was used to establish the structural equation model, and Bootstrap method was used to test the mediating effect.Results:A total of 1 126 questionnaires were distributed, and 1 026 valid questionnaires were collected, with a valid response rate of 91.12% (1 026/1 126). SPBS score of 1 026 stroke patients was (28.68±8.32), the SSS score was (40.53±9.48) and the C-ERRI score was (25.43±12.62). Pearson correlation analysis showed that SPB in stroke patients was positively correlated with stigma and rumination ( P<0.01), and rumination was positively correlated with stigma ( P<0.01). Bootstrap mediating effect test showed that rumination partially mediated the relationship between SPB and stigma in stroke patients, accounting for 55.15% of the total effect. Conclusions:SPB of stroke patients both directly affect stigma and indirectly affect stigma through rumination. Clinical nursing workers should promptly evaluate patients' SPB, pay attention to the mediating role of rumination, develop effective psychological intervention programs, implement personalized and targeted nursing measures, relieve patients' stigma, and improve treatment and rehabilitation compliance.

Objective:To explore the impacts of thermotherapy combined with gemcitabine on the biological behavior of tongue squamous cell carcinoma cells.Methods:Human tongue squamous cell carcinoma Tca8113 cells were divided into the control group (blank control), gemcitabine group, thermotherapy group (heated in an incubator at 43℃ for 1 h and then incubated at 37℃ for 24 h) and thermotherapy + gemcitabine group. The proliferation ability of Tca8113 cells was assessed by EdU staining and CCK-8 assay. Cell apoptosis and cell cycle of Tca8113 cells were detected by flow cytometry. The invasion of Tca8113 cells was determined by Transwell chamber assay. The expression levels of cyclin D1 (CyclinD1), Bcl-2-associated X protein (Bax), matrix metalloproteinase (MMP)-9, phosphorylated histone H2AX (γH2AX) and Nijmegen breakage syndrome 1 (NBS1) proteins in Tca8113 cells were measured by Western blot. The changes of tumor mass and volume were detected by xenograft tumor in vivo test in nude mice. Multi-group comparison was performed by one-way ANOVA. Two group comparison was conducted by SNK- q test. Results:Compared with the control group, EdU positive cell percentage, OD 450 value, invasive cell number, CyclinD1, MMP-9 and NBS1 protein expression of Tca8113 cells were decreased, whereas the apoptosis rate, the expression of Bax and γH2AX proteins were increased in the gemcitabine, thermotherapy and thermotherapy + gemcitabine groups ( q=4.45-72.06, all P<0.001). Compared with the control group, the proportion of G 0/G 1 phase cells was decreased, whereas the proportion of S and G 2/M phase cells was increased in the gemcitabine and thermotherapy + gemcitabine groups, the proportion of G 0/G 1 phase cells was decreased and the proportion of G 2/M phase cells was increased in the hyperthermia group ( q=10.36-61.09, all P<0.001). Compared with the gemcitabine and thermotherapy groups, EdU positive cell percentage, OD 450 value, G 0/G 1 phase cell proportion, invasive cell number, CyclinD1, MMP-9 and NBS1 protein expression of Tca8113 cells were decreased, whereas apoptosis rate, S, G 2/M phase cell proportion, Bax and γH2AX protein expression were increased in the thermotherapy + gemcitabine group ( q=4.45-28.73, all P<0.001). Xenograft tumor in vivo test in nude mice showed that the tumor volume and mass of nude mice in the gemcitabine, thermotherapy, and thermotherapy + gemcitabine groups were decreased compared with those in the control group ( q=5.58-73.02, all P<0.001). Compared with the gemcitabine and thermotherapy groups, the tumor volume and mass in the thermotherapy + gemcitabine group were decreased ( q=5.58-21.45, all P<0.001). Conclusion:The combination of thermotherapy and gemcitabine can inhibit the proliferation and invasion, block the cell cycle, and induce cell apoptosis of Tca8113 cells.
