Objective:To explore the potential profile characteristics of family health in patients with chronic diseases, analyze the influencing factors of different family health categories, and further investigate the relationship between family health categories and the quality of life in patients with chronic diseases, providing a scientific basis for targeted intervention strategies.Methods:This study was a cross-sectional survey. The data for the study were obtained from the Chinese Residents' Psychology and Behavior Survey Research Database. A multistage sampling method was employed to select 1 808 patients with chronic diseases as survey respondents from July to September 2021. Data were collected using the General Information Questionnaire, the Family Health Scale, and the European 5-Dimensional 5-Level Health Scale(EQ-5D-5L). Potential profiles of family health in patients with chronic diseases were identified using latent profile analysis. Univariate analysis and multiple Logistic regression were used to examine influencing factors, and generalized linear regression was performed to analyze the impact of different family health categories on quality of life.Results:A total of 1 808 chronic disease patients were enrolled, comprising 986 males and 822 females, with a age of (55.23 ± 7.02) years. The scores of family health, EQ-5D-5L, EuroQol Visual Analogue Scale were 38(34, 43), 0.94(0.84, 1.00), and 78(63, 87) points. The family health of patients with chronic diseases were categorized into three potential profiles: the low family health group (418 cases accounting for 23.1%), the medium family health group (747 cases accounting for 41.3%), and the high family health group (643 cases accounting for 35.6%). Multivariate Logistic regression analysis showed that family type, marital status, nature of household, education level, number of siblings and type of health insurance were significant factors influencing family health categories ( OR values were 0.464-2.503, all P<0.05). The family health was an important factor influencing quality of life ( χ2 values were 4.05-100.68, all P<0.05). Conclusions:There is significant heterogeneity in the family health of patients with chronic diseases, which can be divided into three distinct categories. Patients with higher family health levels have better quality of life. Medical professionals should develop precise intervention programs tailored to the characteristics of each category to improve family health levels and enhance the quality of life of patients with chronic diseases.

Objective:To understand nurses' experiences providing discharge preparation services for elderly patients with multiple chronic diseases and offer references for developing intervention strategies for discharge preparation services for these patients.Methods:A purposive sampling method was used to select 24 nurses from the cardiovascular departments, geriatrics wards, and other internal medicine departments of three Grade A tertiary hospitals, four Grade B hospitals, and one community health service center in Guilin City between March and April 2024. An interview outline was developed based on the social-ecological system theory, and semi-structured interviews were conducted to collect data. A directed content analysis method was used to analyze the data.Results:A total of three themes were identified: micro-level (nurses have a positive attitude but face shortcomings in age-appropriate discharge preparation services), meso-level (team collaboration mechanisms are weak), and macro-level (there is a desire to link social resources) .Conclusions:Nurses' discharge preparation services for elderly patients with multiple chronic diseases are inadequate. It is recommended to enhance nurses' discharge preparation skills through core competency-based training, improve the development of innovative healthcare platforms, and promote establishing of a multi-dimensional social care support system to improve the quality of discharge preparation services for elderly patients with multiple chronic diseases.

Objective To construct a scientific and practical core literacy training system for nurses working in bleeding centers so as to provide reference for the training and curriculum design of nurses working in bleeding centers.Methods A computerized retrieval of academic papers concerning the core literacy training system for nurses working in bleeding centers from the databases of PubMed,Web of Science,China Biomedical Literature Service(CBM),China Knowledge Network(CNKI),Wanfang and other databases was conducted.Combined with the results of interviews with patients,family members and medical staff,and through organizing the group discussion,a training system for nurses working in bleeding centers was preliminary formulated.Finally,the Delphi method was used to make two rounds of inquiries to 21 experts from 12 provinces,and a three-level index system was determined.Results The first round of expert inquiry questionnaires effectively collected 21/21 consultation letters,and the second round of expert inquiry questionnaires effectively collected 19/21 consultation letters.The expert consultation and judgment coefficient of the core literacy training system for nurses working in bleeding centers was 0.99,the authority coefficient was 0.89;the Miller pyramid theory expert consultation and judgment coefficient was 0.72,the authority coefficient is 0.85,and the familiarity level was 0.80.Finally,the training system for bleeding center nurses covered four levels,including theory,application,skills and practical performance ability,and consisted of three parts,including training content,training management,and exam assessment.The training content included 22 first-level indicators,96 second-level indicators and 78 third-level indicators;the training management included 4 first-level indicators,8 second-level indicators and 12 third-level indicators;and the exam assessment included 5 first-level indicators and 16 second-level indicators.Conclusion The Miller pyramid theory-based core literacy training system for nurses working in hemorrhage centers fully adopts the expert opinions and suggestions,and it carries a high degree of credibility,therefore,it can provide reference for the training of the nurses working in bleeding centers.(J Intervent Radiol,2024,33:664-673)

Objective To investigate the clinical effect of respiratory trainer in the patients with acute exacerbation of chronic obstructive pulmonary disease (COPD) undergoing non-invasive positive pressure ven-tilation.Methods A total of 85 patients with COPD undergoing non-invasive positive pressure ventilation ad-mitted and treated in the Affiliated Minda Hospital of Hubei Nationalities University during 2019-2023 were selected as the study subjects and divided into the experiment group and the control group through random number table method.The control group adopted the symptomatic and supportive treatment such as routine non-invasive positive pressure ventilation,anti-infection,preparation aspiration for spasmolysis and eliminating phlegm,while on the base of the control group,the experiment group adopted respiratory trainer (K5) for re-spiratory training each once in the morning and at night.The differences in the related indexes were compared between the two groups.Results The percentage of forced expiratory volume in the first second (FEV1％),forced expiratory volume in 1 second/forced lung capacity (FEV1/FVC),COPD assessment test (CAT) score,modified Medical Research Council Dyspnea Scale (mMRC) score,6-min walking distance (6MWD),SGRQ score,maximum inspiratory pressure (MIP),maximum expiratory pressure (MEP),partial pressure of carbon dioxide (PaCO2) and PaO2 on 3,7 d after treatment in both groups had statistically significant differ-ence compared with before treatment (P<0.05),and the improvement of the above indicators in the experi-ment group was more significant compared with the control group (P<0.05).Conclusion Respiratory train-er could improve the clinical effect and pulmonary ventilation function in the patients with acute exacerbation of COPD undergoing non-invasive positive pressure ventilation.

Objective To investigate the outcome and affecting factors of patients with osteosarcoma after recurrence.Methods Retrospective analysis was used to analyze the achieved data and prognosis-related factors of 72 patients with extremity osteosarcoma after recurrence from June 2000 to September 2012 through multicenter joint treatment.37 males and 35 females were included.The overall age was 7 to 61 years old (average age22.2 years old).Classification based on the tumor recurrent parts:42 cases (58.3％) on femur,18 cases (25％) on tibia,7 cases (9.7％) on humerus and 5 cases (6.9％) on fibula.Classification based on metastases:14 cases of simple recurrence (19.4％),58 cases (80.6％) of recurrence with metastasis:29 cases (40.3％) of recurrence occurred first,9 cases (12.5％) of metastasis occurred firstly,20 cases (27.8％) of simultaneous recurrence with metastasis;12/14 patients (16.7％) of simple recurrence had long-term survival,but 2 died (2.8％).Six of 58 patients (8.3％) of recurrence with metastasis had long-term survival but 52 died (72.2％).Results The overall 10-year postrelapse survival rate of the 72 patients was 25％.Kaplan-Meier univariate analysis revealed that postrelapse survival was significantly influenced by the continued treatment after recurrence and the number of postoperative chemotherapy,but it was not significantlyinfluenced by age,gender and the number of preoperative chemotherapy.Multivariate analysis revealed that the continued treatment after recurrence and the number of postoperative chemotherapy were independent prognostic factors (P=0.002,P=0.007).At the same time,according to the survival curve grouped by different indicators,the number of chemotherapy after recurrence has no significant effect on TFS.However,the continued treatment after recurrence has obvious statistical significance on improving TFS and OS of patients (P=0.026,P=0.002).Conclusion Resection and standard postoperative chemotherapy had significant effects on the postrelapse survival in patients with osteosarcoma.There are good prospects for further multimodal therapy and multicenter cooperation for osteosarcoma after recurrence.

Objective To explore the reliability and validity of poly ether ether ketone (PEEK) rods and pedicle screw system for lumbar degenerative diseases.Methods Sixty-three patients,including 23 men and 40 women with the mean age of 56.2±5.1 years (range,35-75 years),treated by PEEK rods pedicle screw system from September 2012 to March 2013 were retrospectively recruited.Fusion procedure were performed in 10 patients,with 2 cases at L3,4,5 cases at L4,5,3 cases at L5S1; nonfusion procedure were performed in 17 patients,with 4 cases at L3,4,10 cases at L4,5,3 cases at L5S1; hybrid procedure were performed in 36 patients,with 22 case fusion at L4,5 and nonfusion at L3,4,with 2 cases fusion at L3,4 and nonfusion at L4,5,with 12 cases fusion at L5S1 and nonfusion at L4,5.Clinical effects were evaluated via Japanese Orthopedics Association (JOA) score and Oswestry disfunction index (ODI) at 3 months,6 months and 24 months postoperatively.Disc heights were measured by disc height index on lateral lumbar radiograph.Range of motion (ROM) was measured by extension-flexion lumbar X-ray.Three-dimensional CT reconstruction was achieved to observe the integrity of PEEK rods at the final follow-up.Results The mean follow-up were 23.4±3.3 months.The mean operation time were 110±17 min in the fusion group,98±22 min in the non-fusion group and 121±25 min in the hybrid group.The mean blood loss were 270±85 ml in the fusion group,255±72 ml in the non-fusion group and 316±80 ml in the hybrid group.The JOA score improved from 10.5±2.6 preoperatively to 24.0±3.1 at the final follow-up in the fusion group,from 10.3±2.2 to 24.3±3.4 in the non-fusion group and from 11.1±2.3 to 23.9±3.3 in the hybrid group (P＜0.05).The ODI decreased from 51.8％±10.3％ preoperatively to 14.1％±3.7％ at the final follow-up in the fusion group,from 52.2％±11.1％ to 13.2％±3.2％ in the non-fusion group and from 53.4％±9.2％ to 13.8％±2.5％ in the hybrid group.There was no significantly statistical difference in the disc height index at 3 months,6 months and 24 months postoperatively compared with that at preoperative.The ROM decreased from 8.8°±1.8° preoperatively to 2.2°±0.3° at the final follow-up (P＜0.05).One case demonstrated cage migration at one month follow-up,bony fusion in situ at 3 months follow-up,and the patient had no related symptoms during the follow-up.No screw loosening or breakage and rods breakage was observed during the follow-up.Conclusion PEEK rods and pedicle screw system for lumbar degenerative diseases by fusion,non-fusion and hybrid procedure can achieve considerable clinical outcome with low complication rate.

Objective To evaluate effect and safety of first-line chemotherapy regimen combined with rh-endostatin for osteosarcoma of the extremities.Methods Sixty three patients with osteosarcoma were randomly divided into experiment group and control group.There were 32 patients in experiment group,and 31 patients in control group.Nine patients 9 were rejected because they did not meet the standard.Finally,54 patients were enrolled in this study,including 29 patients in experiment group,and 25 patients in control group.In the experiment group,the patients were treated with rh-endostatin combined with MTX,IFO,DDP,and ADM,while patients in control group were treated with MTX,IFO,DDP,and ADM.Several indexes including median progression-free survival time,clinical benefit rate,progression-free survival rate,limb salvage rate,and survival rate were used to assess clinical effect.The safety of rh-endostatin was evaluated by comparing incidence of adverse events in the two groups.Results The median progression-free survival time of experiment group and control group was 18.9 months and 13.1 months,respectively; there was no significant difference.In the experiment group,the clinical benefit rate,progression-free survival rate,survival rate and limb salvage rate were 89.7％,37.9％,65.5％,and 89.7％,respectively; while in the control group,the clinical benefit rate,progression-free survival rate,survival rate,and limb salvage rate were 88.0％,36.0％,68.0％,and 96.0％,respectively.There was no significant difference in 4 indexes mentioned above between two groups.Conclusion After being combined with first-line chemotherapy regimen,rh-endostatin doesn't show significant advantage in controlling tumour progression and improving survival rate.No more toxicity and new side effects are found after using rh-endostatin.

Objective:To improve the sensitivity and the linear range of electrochemical immunosensor to detect Schistosoma japonicum (S.japonicum) antibody.Methods:Carbon inks and silver/silver chloride inks were printed on a polyethylene terephthalate (PET) board to make a two-electrode test strip,where carbon was the working electrode and S.japonicum soluble egg antigen (SEA) was fixed at one end of working electrode by different methods; silver/silver chloride electrode was used as control.We tested the valency of the antibody by cyclic voltammetry (CV) and differential pulse voltammetry (DPV) in an electrochemistry workstation,and conducted comparison with the results of ELISA.Two new immunosensing electrodes have been developed,based on glutaraldehyde cross-linked (GA) or chitosan-glutaraldehyde cross-linked (Chit-GA) transducer fixing S.japonicum antigen.We tested the titer of the antibody by means of CV and DPV.Results:Our experimental S.japonicum antigen (50 μg/L) is the optimal test concentration for the GA sensor,and 10 μg/L for Chit-GA sensors.The immune reaction time of both electrodes is all essentially complete in 1 minute.The linear range for S.japonicura antibody in human positive serum sample detection by the glutaraldehyde cross-linked immunosensor is 1∶1000 to 1∶400,and by the chitosan-glutaraldehyde cross-linked immunosensor is 1∶1000 to 1∶500.As the concentration of dilution ratio of S.japonicum antibody in human positive serum sample increased,the test value of DPV increased proportionally.Conclusion:GA sensor and Chit-GA cross-linked S.japonicum sensors have high sensitivity and broad linear range response,and both exhibited a good linear relationship between the DPV signal and the test antibody titer.
