Purpose: This research observed the efficacy and safety of soft tissue expansion combined with recombinant human epidermal growth factor (rhEGF) in repairing second-degree scald scars. Methods: This study conducted a prospective, single-blind, randomized controlled trial. Eighty-four patients with deep second-degree scald scars were evenly divided into the control and observation groups. The control group was treated with soft tissue expansion, and the observation group was additionally treated with rhEGF. The skin expansion and wound healing times were compared. The changes in wound exudate and inflammation around the wound were observed after first-stage surgery. The hydroxyproline (OHP) and collagen I/III ratios were compared during the second stage of surgery.The complications and repair effects during treatment were evaluated. Results: The observation group exhibited lower expansion time, immediate retraction rate, and wound healing time, higher skin expansion rate, higher wound exudate score and inflammation score, higher OHP, lower collagen I/III, lower complication rate, and higher total effective rate than the control group (all P < 0.05). Conclusion Skin soft tissue expansion combined with rhEGF is more effective in repairing second-degree scald scars, which can effectively increase skin expansion area and reduce wound infection and complications.

Objective:To explore the effects of body mass index (BMI) on the incidence of nocturnal hypertension in patients with hypertension.Methods:Totally 341 hospitalized hypertensive patients treated at the Affiliated Hospital of Jining Medical University from February to May 2023 were selected by convenience sampling. Patients' general information, clinical data, and 24-hour ambulatory blood pressure results were collected. A binomial Logistic regression analysis was conducted to investigate the factors affecting the occurrence of nocturnal hypertension in these patients. The relationship between BMI and the incidence of nocturnal hypertension was examined using threshold effect tests and smooth curve fitting.Results:The binomial Logistic regression analysis indicated that blood phosphate level was a factor influencing the occurrence of nocturnal hypertension in hypertensive patients ( P<0.05). Smooth curve fitting and threshold effect test results showed that the relationship between BMI and the incidence of nocturnal hypertension was curve-correlated, with a turning point at 24.61 kg/m 2. To the left of the turning point, there was no correlation ( P=0.130) ; to the right, there was a correlation ( P=0.016) . Conclusions:When the BMI of hypertensive patients exceeds 24.61 kg/m 2, the likelihood of nocturnal hypertension increases with rising BMI, providing a precise intervention target for weight management-based patient care in hypertension.

Objective:To explore the chain mediation role of career development planning and career success in the relationship between nurses' professional values and occupational embeddedness.Methods:From February to March 2024, a convenience sampling method was used to select 763 nurses from ClassⅢ Grade A hospitals in Wenzhou as research subjects. Data were collected using a General Information Questionnaire, the Occupational Embeddedness Scale for Nurses (OESN), the Nursing Professional Values Scale-Revised (NPVS-R), the Nurses' Career Planning Questionnaire (NCPQ), and the Career Success Scale for Nurses (CSSN). Pearson correlation analysis was performed to examine the correlations among the scores of OESN, NPVS-R, NCPQ, and CSSN. The AMOS 21.0 software was used to construct a structural equation model to explore the chain mediation role of career development planning and career success in the relationship between nurses' professional values and occupational embeddedness.Results:A total of 763 questionnaires were collected, with 749 valid responses, resulting in an effective recovery rate of 98.17%. The average scores for the 749 nurses were as follows: OESN (60.29±7.65), NPVS-R (108.99±11.82), NCPQ (42.98±4.44), CSSN (73.57±8.34). All four scale scores were positively correlated with each other ( P<0.05). The chain mediation effect of career development planning and career success in the relationship between nurses' professional values and occupational embeddedness was established, with the total indirect effect accounting for 46.04% (0.302/0.656) of the total effect and the chain mediation effect of career development planning and career success accounting for 10.21% (0.067/0.656) . Conclusions:The level of occupational embeddedness among nurses needs further improvement. Nurses' professional values not only directly influence their level of occupational embeddedness but also affect their career development planning, which in turn impacts their career success, ultimately exerting an indirect effect on occupational embeddedness. Nursing managers should strengthen nurses' professional values, assist them in formulating clear career development plans, and provide timely feedback and recognition of career success.

Objective To develop a whole course management information system for breast cancer and verify its effect in disease management of breast cancer patients.Methods An integrated service plan and system construction of"screening-diagnosis-treatment-rehabilitation"was developed,and then an information system was developed.The method of historical control was used to conveniently sample 260 cases of breast cancer patients diagnosed in a tertiary A hospital.130 cases diagnosed from May 1 to December 31,2022 were taken as a test group,and 130 cases diagnosed from May 1 to December 31,2021 were taken as a control group.The test group was managed by the whole course management information system,and the control group was managed by conventional disease management.The relevant indicators of the screening and diagnosis period of patients,the completion rate of treatment,the incidence of treatment related side effects and the cancer care satisfaction of the 2 groups were compared.Results There was a statistically significant difference in puncture waiting time,admission waiting time,and screening admission time between the 2 groups(P＜0.05),while there was no statistically significant difference in pathological waiting time(P＞0.05).The treatment completion rate of the test group was higher(P＜0.05).The incidence of lymphedema,chest obstruction and abnormal sensation of upper limbs,subcutaneous hydrops within 6 months after operation and bone marrow suppression,liver function damage,radiation dermatitis and radiation pneumonia in the test group were lower than those in the control group(P＜0.05).The cancer care satisfaction of the test group after surgery and 6 months after surgery were higher than those of the control group(P＜0.05).Conclusion The whole course management information system for breast cancer can optimize the diagnosis and treatment process,raise the diagnosis and treatment efficiency,ensure the treatment completion rate,reduce the treatment complications and improve the cancer care satisfaction.

Objective To investigate the status of application of the central venous access in the departments of hematology to develop targeted administrative strategies and provide evidence for management.Methods A self-de-signed questionnaire was applied and convenience sampling was adopted in 93 hematology departments from 48 hospitals in 19 provinces(autonomous regions,municipalities).Results A total of 91 valid questionnaires were col-lected,with a valid questionnaire response rate of 97.85％.Among the 91 hematology departments,91(100％),73(80.22％),and 68(74.73％)carried out PICC,central venous catheter,and totally implantable access port catheteriza-tion,respectively.In the evaluation of blood test indicators before central venous access,the items with a higher e-valuation proportion were platelet count(100％)and D-dimer concentration(87.91％),while the evaluation proportion of other items was＜85％.When PICC catheterization,97.80％of hematology departments prefer basilic vein;83.52％of hematology departments used zone insertion method;95.60％of hematology departments had a skin disinfection range of ≥20 cm;98.90％of hematology departments had catheterization under ultrasound guidance;67.03％and 96.70％of hematology departments used the intracardiac electrocardiogram method or ultrasound assisted localiza-tion,postoperative X-ray localization;12.09％and 53.85％of hematology departments carried out tunnel catheteriza-tion and blunt separation expansion techniques,respectively.In terms of maintenance of central venous access de-vices,82.42％of hematology departments used disposable specialized maintenance kits;61.54％of hematology de-partments used transparent patches to fix PICC;45.21％of hematology departments used suture to fix central venous catheters;24.18％of hematology departments used cotton swabs to disinfect infusion joints;60.44％of hematology departments did not use disposable infusion joint disinfection cap;74.73％of hematology departments used gauze compression to prevent puncture site bleeding;only 6.59％hematology departments used antibacterial dressings con-taining chlorhexidine to prevent puncture site infections.In terms of quality management of central venous access devices,94.51％and 86.81％of hematology departments regularly conducted quality inspections of central venous access,and collected,calculated and analyzed relevant data.50.55％of hematology departments conducted complica-tion risk assessments,and 10.99％of hematology departments had established information management systems for venous therapy.Conclusion The implementation rate of PICC catheterization in the hematology department was relatively high,and the insertion operation basically meets the standard requirements.The evaluation before central venous access catheterization was relatively completed,and the maintenance and management are relatively stan-dardized.However,the evaluation of blood test indicators before the placement of central venous access urgently needs to be standardized and unified.When PICC catheterization,attention should be paid to the application of new technologies,and the information management of venous therapy needs to be improved.
