Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease. As a critical component of surgical repair, reconstruction of the right ventricular outflow tract (RVOT) serves as a primary determinant of postoperative hemodynamics and long-term prognosis. With advancements in surgical techniques, early postoperative survival rates for TOF have significantly improved, shifting clinical focus toward addressing long-term complications such as right ventricular dysfunction and reduced exercise tolerance. However, challenges persist regarding optimal timing of surgery in relation to adverse long-term outcomes, balancing RVOT reconstruction strategies, and selecting appropriate repair materials for RVOT reconstruction, with a lack of unified high-level evidence-based guidelines. To address these issues and standardize the application of radical corrective surgery for TOF to better serve patients, the National Society for Congenital Heart Diseases has systematically reviewed existing high-level evidence. Consequently, we have registered and formulated the "Protocol for Chinese expert consensus on right ventricular outflow tract reconstruction in tetralogy of Fallot (2026 edition)", which details the methodology and development process of this upcoming consensus.

Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease. Right ventricular outflow tract (RVOT) reconstruction, as the core technical step of radical surgery, plays a decisive role in postoperative hemodynamics and long-term quality of life. With the substantial improvement in early survival after TOF repair, clinical focus has progressively shifted toward the prevention and management of late complications, including right ventricular dysfunction, impaired exercise capacity, and the need for reintervention. However, RVOT reconstruction strategies and the selection of repair materials remain controversial. To standardize the clinical practice of definitive TOF repair, the National Society for Congenital Heart Diseases developed this expert consensus, focusing on three domains: postoperative outcomes after TOF repair, RVOT reconstruction strategies, and the reconstructive materials.

Objective To investigate the correlation between skeletal muscle mass index(ASMI)and islet β cell reserve function in patients with newly diagnosed type 2 diabetes mellitus(T2DM).Methods A total of 100 patients with newly diagnosed T2DM were included in this study.All the patients were admitted to the Department of Endocrinology in the First People's Hospital of Yinchuan between June 2022 and November 2023.They were divided into two groups according to their skeletal muscle mass index(ASMI):patients with T2DM accompanied by sarcopenia(Sar,n=50)group,and patients with simple T2DM(T2DM,n=50)group.Additionally,a control(NC)group consisting of 50 healthy participants was selected.Fasting C-peptide levels,liver and kidney function,blood lipid profiles,and other indicators were assessed in all the individuals.The correlation between ASMI and other indicators was analyzed,and the influencing factors for ASMI and T2DM combined with sarcopenia were analyzed respectively.Results The levels of HbA1c,FPG,and TG were higher,while FC-P and Scr levels were lower in the T2DM group and Sar group compared with the NC group(P<0.05).FPG was higher,while ASMI,FC-P,BMI were lower in the Sar group than in the T2DM group(P<0.05).Spearman correlation analysis revealed a negative correlation between ASMI and FPG and HbA1c(P<0.05),whereas a positive correlation was observed with BMI,ALT,Scr,SUA and FC-P(P<0.05).Multiple linear regression analysis indicated that BMI,HbA1c and FC-P were influencing factors for ASMI(P<0.05).Furthermore,logistic regression analysis demonstrated that BMI,HbA1c,FC-P were influencing factors for T2DM with sarcopenia(P<0.05).Conclusions The level of ASMI may be related to the reserve function of islet β cells.

Objective To develop an innovative minimally invasive rotary-cutting surgical system for axillary osmidrosis,and conduct clinical validation.Methods The design concept,technical principles and system composition of the innovative minimally invasive rotary-cutting surgical system for axillary osmidrosis were introduced.A total of 73 patients(146 axillae)with axillary osmidrosis were enrolled as subjects,and underwent surgery using the newly developed surgical system.Clinical validation of the system was performed by evaluating postoperative scarring,odor elimination rate,postoperative complication incidence,and patient satisfaction.Results The study demonstrated favorable clinical outcomes in the following aspects:postoperative scarring,odor elimination rate,postoperative complication incidence,and patient satisfaction.Conclusion The minimally invasive rotary-cutting surgical system for axillary osmidrosis is rationally designed.The rotary-cutting puncture device is safe,effective,minimally invasive,and convenient for axillary osmidrosis surgery,warranting further clinical validation and widespread application.

Objective To investigate the expression of ferritinophagy-related gene ELAV-like RNA binding protein 1(ELAVL1)in multiple myeloma(MM)and elucidate its diagnostic and prognostic value for MM.Methods First,we analyzed ELAVL1 expression level in healthy controls and MM patients using data from the GEO and TCGA databases.Subsequently,bone marrow specimens were collected from 28 newly diagnosed MM patients and 20 healthy controls,and qRT-PCR was employed to validate ELAVL1 expression.The diagnostic and prognostic potential of ELAVL1 was assessed using ROC curve analysis and Kaplan-Meier survival curves.Additionally,univariate and multivariate COX regression analyses were performed to identify independent risk factors for MM prognosis.Finally,KEGG and GO enrichment analyses were performed using the DAVID online platform.Results The level of ELAVL1 expression was significantly higher in newly diagnosed MM patients and refractory/relapsed MM patients than in the healthy controls(P＜0.001).Moreover,ELAVL1 expression was positively correlated with the International Staging System(ISS)stage of MM(P＜0.01).Furthermore,qRT-PCR validation confirmed that ELAVL1 expression was elevated in the 28 newly diagnosed MM patients compared to the 20 healthy controls(P＜0.001).ROC curve analysis demonstrated that ELAVL1 could effectively differentiate between newly diagnosed MM patients,healthy controls,and MGUS patients(P＜0.001 and P=0.000 2,respectively).Survival analysis revealed that high ELAVL1 expression was associated with shorter progression-free survival(P=0.0141)and overall survival(P=0.008 0).Univariate and multivariate COX regression analyses identified high ELAVL1 expression as an independent risk factor for poor MM prognosis(P=0.005 0).KEGG analysis suggested that ELAVL1 might be involved in the Hippo and MAPK signaling pathways.Conclusion High ELAVL1 expression in MM may serve as a biomarker for diagnosis and poor prognosis.ELAVL1 may promote MM initiation and progression via the Hippo and MAPK signaling pathways.

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 explore the related factors between Helicobacter pylori(Hp)infection and upper gastrointestinal bleeding in the patients with acute myocardial infarction.Methods A total of 180 pa-tients with acute myocardial infarction hospitalized in the department of cardiovascular medicine of Shaanxi Provincial People's Hospital from May 2021 to May 2023 were selected as the study subjects.The general condition of the patients was recorded,the relevant blood biochemical indexes of the patient were recorded,the 3C urea breath test was used to detect Hp,and the expression levels of VEGF,VCAM-1 and CTRP9 were de-termined by ELISA.All study subjects were followed up in 3 months after discharge,and the major adverse cardiac events(MACE)and upper gastrointestinal bleeding events during the follow-up period were recorded.Results Among the 180 study subjects,78 cases(43.33％)were Hp-negative and 102 cases(56.67％)were Hp-positive.The Hb level in Hp-positive patients was lower than that in Hp-negative patients,the levels of IL-6,IL-8,TNF-α,and C-reactive protein were higher than those in Hp-negative patients,and the differences were statistically significant(P＜0.05).The levels of VEGF and VCAM-1 in Hp-positive patients were high-er than those in Hp-negative patients,the level of CTRP9 was lower than that in Hp-negative patients,and the differences were statistically significant(P＜0.05).The results of logistic regression analysis showed that Hb,IL-6,IL-8,TNF-α and C-reactive proteins were the independent influencing factors in predicting Hp infec-tion(P＜0.05).The incidence rate of upper gastrointestinal bleeding events in Hp-positive patients was high-er than that in Hp-negative patients,and the difference was statistically significant(P＜0.05).Hp positivity,Hb and C-reactive protein were the independent influencing factors in predicting the occurrence of upper gas-trointestinal bleeding(P＜0.05).Conclusion The incidence rate of Hp infection in the patients with acute myocardial infarction is high,and the Hp positivity could promote the changes in the levels of various cyto-kines and further aggravate coronary artery injury.Hp infection may increase the incidence rate of upper gas-trointestinal bleeding in the patients with acute myocardial infarction.

Background and Objectives: The Fractional Flow Reserve and Intravascular UltrasoundGuided Intervention Strategy for Clinical Outcomes in Patients with Intermediate Stenosis (FLAVOUR) trial demonstrated non-inferiority of fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) compared with intravascular ultrasound (IVUS)-guided PCI. We sought to investigate the cost-effectiveness of FFR-guided PCI compared to IVUS-guided PCI in Korea. Methods: A 2-part cost-effectiveness model, composed of a short-term decision tree model and a long-term Markov model, was developed for patients who underwent PCI to treat intermediate stenosis (40% to 70% stenosis by visual estimation on coronary angiography).The lifetime healthcare costs and quality-adjusted life-years (QALYs) were estimated from the healthcare system perspective. Transition probabilities were mainly referred from the FLAVOUR trial, and healthcare costs were mainly obtained through analysis of Korean National Health Insurance claims data. Health utilities were mainly obtained from the Seattle Angina Questionnaire responses of FLAVOUR trial participants mapped to EQ-5D. Results: From the Korean healthcare system perspective, the base-case analysis showed that FFR-guided PCI was 2,451 U.S. dollar lower in lifetime healthcare costs and 0.178 higher in QALYs compared to IVUS-guided PCI. FFR-guided PCI remained more likely to be cost-effective over a wide range of willingness-to-pay thresholds in the probabilistic sensitivity analysis. Conclusions Based on the results from the FLAVOUR trial, FFR-guided PCI is projected to decrease lifetime healthcare costs and increase QALYs compared with IVUS-guided PCI in intermediate coronary lesion, and it is a dominant strategy in Korea.
