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.

BACKGROUND:
Lung adenocarcinoma (LUAD) is the predominant subtype of non-small cell lung cancer (NSCLC). Damage-specific DNA binding protein 1 (DDB1), as a core protein of the CUL4-DDB1 ubiquitin ligase complex, is involved in the regulation of DNA damage repair, epigenetic modification, and cell cycle checkpoint activation. While the involvement of DDB1 in tumour progression through DNA repair and RNA transcriptional regulation has been reported, its expression and role in LUAD remain to be elucidated. This study aims to investigate the expression and role of DDB1 in LUAD.
METHODS:
The expression, clinicopathological features and prognosis of DDB1 in LUAD were analysed using databases such as UALCAN, Kaplan-Meier Plotter and GEPIA; The interaction network and enriched functional pathways were constructed by GeneMANIA and Metascape; the correlation between DDB1 and immune cells by combining with TISIDB infiltration was evaluated, and the clustering results of cell subtypes and the expression of DDB1 in different immune cell subpopulations were analysed by single-cell sequencing; finally, tissue microarrays were used to further verify the expression and prognostic value of DDB1 in LUAD.
RESULTS:
The mRNA and protein expression of DDB1 in LUAD tissues were significantly higher than those in normal tissues (P<0.01), and the high expression correlated with later clinical stage (P<0.001), lymph node metastasis (P<0.001) and poor prognosis (P<0.001). Functional enrichment showed that DDB1 was involved in DNA repair and RNA transcriptional regulation, and TISIDB evaluation revealed that DDB1 was negatively correlated with the expression level of immune cells, suggesting the potential regulation of the immune microenvironment. Single cell analysis showed that DDB1 was mainly expressed in T cells, alveolar macrophages and dendritic cells. Tissue microarrays confirmed that overall survival was shorter in the DDB1 high expression group (P<0.001), and Cox multifactorial analysis showed that DDB1 was an independent predictor of LUAD prognosis.
CONCLUSIONS
DDB1 is highly expressed in LUAD, which is associated with poor prognosis, and is closely related to tumor immune cell infiltration, and is involved in tumourigenesis and development through DNA repair and RNA transcriptional regulation. DDB1 can be used as a potential prognostic marker and therapeutic target for LUAD.

Mitochondrial dysfunction is a critical factor in the pathogenesis of Alzheimer's disease (AD). The mitochondrial contact site and cristae organizing system (MICOS) plays a pivotal role in shaping the inner mitochondrial membrane, forming cristae junctions and establishing interaction sites between the inner and outer mitochondrial membranes and thereby serving as a cornerstone of mitochondrial structure and function. In the past decade, MICOS abnormalities have been extensively linked to AD pathogenesis. In particular, dysregulated expression of MICOS subunits and mutations in MICOS-related genes have been identified in AD, often in association with hallmark pathological features such as amyloid-β plaque accumulation, neurofibrillary tangle formation, and neuronal apoptosis. Furthermore, MICOS subunits interact with several etiologically relevant proteins, significantly influencing AD progression. The intricate crosstalk between these proteins and MICOS subunits underscores the relevance of MICOS dysfunction in AD. Therapeutic strategies targeting MICOS subunits or their interacting proteins may offer novel approaches for AD treatment. In the present review, we introduce current understanding of MICOS structures and functions, highlight MICOS pathogenesis in AD, and summarize the available MICOS-targeting drugs potentially useful for AD.

Objective To summarize and explore the individualized surgical treatment strategy and prognosis of anomalous aortic origin of coronary artery (AAOCA). Methods The clinical data of children with AAOCA admitted to Shanghai Children's Medical Center from March 2018 to August 2021 were retrospectively analyzed. Results A total of 17 children were enrolled, including 13 males and 4 females, with a median age of 88 (44, 138) months and a median weight of 25 (18, 29) kg. All patients received operations. The methods of coronary artery management included coronary artery decapitation in 9 patients, coronary artery transplantation in 5 patients and coronary artery perforation in 3 patients. One patient with severe cardiac insufficiency (left ventricular ejection fraction 15%) received mechanical circulatory assistance after the operation for 12 days. No death occurred in the early postoperative period, the average ICU stay time was 4.3±3.0 d, and the total hospital stay was 14.4±6.1 d. All the children received regular anticoagulation therapy for 3 months after discharge. The median follow-up time was 15 (13, 24) months. All patients received regular anticoagulation therapy for 3 months after discharge. No clinical symptoms such as chest pain and syncope occurred again. The cardiac function grade was significantly improved compared with that before operation. Imaging examination showed that the coronary artery blood flow on the operation side was unobstructed, and no restenosis occurred. Conclusion AAOCA is easy to induce myocardial ischemia and even sudden cardiac death. Once diagnosed, operation should be carried out as soon as possible. According to the anatomic characteristics of coronary artery, the early effect of individualized surgery is satisfactory, and the symptoms of the children are significantly improved and the cardiac function recovers well in the mid-term follow-up.

ObjectiveTo explore the characteristics and major factors influencing mental health literacy (MHL) among non-graduating middle school and high school students in Taizhou, Zhejiang Province, and to provide a reference for the promotion of mental health literacy among adolescents. MethodsFrom September to October 2023, a stratified random cluster sampling method was used to conduct a questionnaire survey among students from three classes each in non-graduating grades in four middle schools and four high schools in Taizhou, Zhejiang Province. The survey included basic demographic information, a Structured Mental Health Literacy Questionnaire (MHLQ), and other psychological scales [Educational Stress Scale for Adolescents (ESSA), Perceived Choice Single Scale (PC), Child Depression Inventory (CDI), Generalized Anxiety Disorder (GAD), The University of California at Los Angeles 3-item Loneliness Scale (UCLA-3) and Multidimensional Scale of Perceived Social Support (MSPSS)]. t-tests, chi-square tests, analysis of variance (ANOVA), and multiple linear regressions were applied for the statistical analysis of the data. ResultsThe mental health literacy average score of 2 094 students was (82.3±15.8) points, with a mean of (4.1±0.8) points. The dimension of belief in mental health rights had the highest score. There were significant differences in the mental health literacy score across different dimensions for students with different household registration, economic levels, academic performance, and father’s education level (P<0.001). Multiple linear regression analysis indicated that rural household registration, lower paternal education level, greater academic pressure, a weaker sense of control over one’s behavior, less social support, and symptoms of loneliness, depression, or anxiety were associated with poorer mental health literacy among the students. ConclusionThe mental health literacy of middle school and high school students in Taizhou is generally good, but there are differences among students with different characteristics. Targeted interventions should be carried out for students from rural areas, with poorer mental health, and less low social support to improve the overall mental health literacy of adolescents.
