Objective:To investigate the current status and influencing factors of decision anxiety in guardians of children with acute appendicitis under Endoscopic retrograde appendicitis therapy (ERAT) background, and to provide reference for the development of targeted intervention programs for decision anxiety.Methods:Convenient sampling method was used to select 254 guardians of children with acute appendicitis treated in the Department of Pediatrics, Second Affiliated Hospital of PLA Air Force Medical University from February 2023 to April 2024. A cross-sectional survey was conducted using the General Data Questionnaire, the State-Trait Anxiety Inventory Form Y-State anxiety subscale and the Preparation for Decision Making Scale. Multiple linear regression was used to analyze the influencing factors in guardians of children with acute appendicitis.Results:Among the guardians of 254 children with acute appendicitis, 156 were males and 98 were females, aged (37.44 ± 3.63) years old. The decision anxiety score of guardians of children with acute appendicitis was (52.49 ± 6.54). The results of multiple linear regression showed that age of children, gender of guardian, education level of guardian, per capita monthly income of family, decision making tendency and decision preparation were the main influencing factors of decision anxiety in guardians of children with acute appendicitis ( t values were -7.07-3.58, all P<0.05), which could explain 64.4% of the total variation. Conclusions:The decision anxiety in guardians of children with acute appendicitis is at a high level. Medical staff should provide targeted decision guidance, improve decision assistance programs and provide more effective decision support for guardians of children with acute appendicitis.

Objective:This study used data-independent acquisition (DIA) proteomics to analyze plasma protein expression in sepsis-induced coagulopathy (SIC), identify key biomarkers, and develop a diagnostic model.Methods:This prospective study included 46 adult sepsis patients from the intensive care unit. Patients were categorized into a general sepsis group ( n=26) and an SIC group ( n=20) based on established SIC criteria. Plasma samples underwent proteomic and bioinformatics analyses to identify differentially expressed protein (DEP) using LASSO regression and Random Forest. A diagnostic model was constructed and assessed via receiver operating characteristic (ROC) curve analysis. Results:The baseline data revealed that SIC patients exhibited longer prothrombin times, lower platelet counts, and higher D-dimer, fibrin degradation products, blood lactate, SOFA scores, and APACHE Ⅱ scores compared with general sepsis patients ( P<0.05). DIA proteomics identified 2 637 proteins, with 240 DEP meeting the criteria (fold change >1.5, P<0.05), including 81 upregulated and 159 downregulated DEP. Subcellular localization analysis revealed that DEPs were predominantly extracellular and nuclear. Gene ontology (GO) annotation showed that DEP were mainly involved in cellular physiology, biological regulation, and stress response processes in biological processes. Domain annotation revealed a predominance of immunoglobulin V regions in DEP, which are crucial for antigen recognition and binding. KEGG enrichment analysis showed significant enrichment of DEP in pathways related to natural killer cell-mediated cytotoxicity, glycosylphosphatidylinositol anchor biosynthesis, tumor necrosis factor signaling, and NF-κB signaling. LASSO regression identified angiogenin and C-type lectin domain family 10 member A as key DEP. The SIC diagnostic nomogram showed an area under the curve of 0.896, with 0.731 specificity and 0.900 sensitivity. Conclusion:The nomogram incorporating angiogenin and C-type lectin domain family 10 member A provides an accurate tool for SIC diagnosis.

Objective To explore and analyze the application effect of the digital information management mode of nurs-ing"teaching-training-clinical"work in operating room teaching.Methods 100 nursing students who interned in the operating room of Gaozhou Hospital of Traditional Chinese Medicine from April 2023 to February 2024 were selected as the research sub-jects.They were divided into an observation group(digital information management mode of"teaching-training-clinical"work)and a control group(traditional teaching mode)by random number table method,with 50 students in each group.The teaching effects of the two groups were compared.Results The theoretical and practical scores and core competency scores of the obser-vation group after teaching were significantly higher than those of the control group.The observation group had higher satisfaction with the teaching plan,teaching content,teaching methods,teaching achievements,and teaching ability,and the comparison was statistically significant(P＜0.05).The long-term teaching results of the observation group,including theoretical and practical assessment results and core competency assessment results,were higher than those of the control group(P＜0.05).Conclusion The digital information management mode of"teaching-training-clinical"work can improve the teaching quality of operating room teaching and enhance the working ability of nursing students.

Objective To investigate the protective effect and mechanism of RhoE overexpression in angiotensin Ⅱ-induced myo-cardial fibrosis.Methods Primary cardiomyocytes were cultured in vitro using angiotensin Ⅱ-induced myocardial fibrosis model,and transfected with M-RhoE-carrying overexpressing adenovirus and overexpressing RhoE according to subgroup.α-SMA and Smad3 ex-pression distribution in primary cardiomyocytes were detected by immunofluorescence.The protein expression levels of RhoE,GAPDH,α-SMA,Smad3 and p-Smad3 in primary cells were detected by Western blotting.Results Ang Ⅱ interferes with primary cardiomyo-cytes.Western-blot analysis showed that compared with the control group,the expression levels of p-Smad3 and α-SMA in Ang Ⅱgroup were increased,while the expression levels of RhoE were decreased(P＜0.05).After transfection of RhoE overexpressing adenovi-rus,Western blot results showed that the α-SMA expression level in Ang Ⅱ group was increased compared with that in the control group(P＜0.05).Compared with Ang Ⅱ group α-SMA expression level in Ang Ⅱ+Ad-RhoE group was significantly decreased(P＜0.05).Immunofluorescence detection showed that the α-SMA fluorescence intensity in Ang Ⅱ group was increased compared with that in control group(P＜0.05).Compared with Ang Ⅱ group α-SMA fluorescence intensity in Ang Ⅱ+Ad-RhoE group was significantly decreased(P＜0.05).Effects of overexpression of RhoE gene on TGF-β1/Smad3 pathway.Western blot results showed that compared with the control group,the p-Smad3/Smad3 ratio in Ang Ⅱ group was increased(P＜0.05).Compared with Ang Ⅱ group,the p-Smad3/Smad3 ratio in Ang Ⅱ+Ad-RhoE group was significantly decreased(P＜0.05).Immunofluorescence nuclear translocation showed that compared with the control group,the red fluorescence in myocardial nucleus of Ang Ⅱ group was significantly increased(P＜0.05).Compared with Ang Ⅱ group,the red fluorescence in myocardial nucleus of Ang Ⅱ+Ad-RhoE group was significantly decreased(P＜0.05).Conclusion The process of Ang Ⅱ-induced myocardial fibrosis is accompanied by the activation of TGF-β1/Smad3 sig-naling pathway,and RhoE can inhibit Ang Ⅱ-induced myocardial fibrosis by inhibiting TGF-β1/Smad3 signaling pathway.

Objective:To analyze and explore the selection of secondary intervention strategies for residual issues following congenital aortic valve disease surgery in children, as well as to evaluate their prognostic efficacy.Methods:A retrospective analysis was conducted on the clinical data of 41 children with residual issues after congenital aortic valve disease surgery, who were treated at the Department of Cardiovascular and Thoracic Surgery, Shanghai Children's Medical Center, between January 2013 and August 2024. Among them, 25 were male and 16 were female, with a mean age of(116.8±45.1)months and a mean weight of(40.0±20.2)kg. The mean interval for secondary intervention was(60.0±36.4)months. The residual issues included aortic valve insufficiency(20 cases), aortic valve stenosis(11 cases), and combined aortic valve insufficiency and stenosis(10 cases).Results:Secondary interventions included aortic valve repair(7 cases), mechanical valve replacement(20 cases), Ross procedure(13 cases), and Ozaki procedure(1 case). Additionally, 5 cases with left ventricular outflow tract stenosis underwent concomitant Konno surgery.One case of early postoperative in-hospital death occurred, with a mortality rate of 2.4%, primarily due to acute left heart failure and multiple organ dysfunction. The average follow-up period for surviving children was( 64.6±34.5) months(5-147 months), with no mid- to long-term mortality. Follow-up results showed that In surviving children, the left heart showed significant reduction in size postoperatively, with the LVEDD Z-score decreasing from 1.24±2.23 before surgery to -0.97±1.48( P=0.001). Postoperative LVEF 0.66±0.06 showed no significant difference compared to pre-reintervention 0.68±0.10( P=0.140). In aortic stenosis(AS) patients, the peak transvalvular pressure gradient decreased from(69.5±19.8) mmHg(1 mmHg=0.133 kPa) preoperatively to(25.1±10.9) mmHg postoperatively( P=0.003). In aortic insufficiency(AI) patients, the width of the aortic regurgitation jet decreased from(5.8±1.1) mm preoperatively to(2.7±1.1) mm postoperatively( P=0.012). 97.5% of children maintained mild-to-moderate aortic regurgitation(jet width <4 mm), with only 1 case of moderate regurgitation(jet width 4.4 mm)remaining under close observation.Two children underwent reoperation on the aortic valve, with a tertiary intervention rate of 5.0%. One case underwent redo commissurotomy 21 months after aortic valve repair due to recurrent stenosis, and the other underwent mechanical valve replacement 34 months after the Ozaki procedure due to leaflet calcification and infective endocarditis. Mid-term follow-up revealed good cardiac function recovery in surviving children, with 87.5% achieving NYHA functional class Ⅰ/Ⅱ. Conclusion:Due to the demands of growth and development and the degenerative nature of valve tissue, residual issues are inevitable in the mid- to long-term following congenital aortic valve disease surgery in children, often necessitating secondary intervention. Given the lack of suitable autologous valve tissue, the use of aortic valve replacement has significantly increased in secondary interventions. The Ross procedure, as an ideal secondary intervention, demonstrates satisfactory mid-term follow-up outcomes. For children with high-risk factors for the Ross procedure, mechanical valve replacement also yields favorable prognoses.
