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 and Objectives: Heart failure is a potentially fatal event caused by diverse cardiovascular diseases, leading to high morbidity and mortality. Histone deacetylase (HDAC) inhibitors positively influence cardiac hypertrophy, fibrosis, hypertension, myocardial infarction, and heart failure, causing some side effects. We aimed to investigate the effect of the novel HDAC inhibitor YAK577 on the heart failure mouse model and its underlying mechanism. Methods: New hydroxamic acid YAK577 was prepared via methyl-2,3-diphenylpropanoate synthesis using carboxylic acids. We used a micro-osmotic pump, including isoproterenol (ISO; 80 mg/kg/day), to induce a heart failure with reduced ejection fraction. Cardiac hypertrophy was assessed by heart weight to body weight ratio and cross-sectional area.The left ventricular (LV) function was assessed by echocardiography. Fibrosis was evaluated using picrosirius red staining. Overexpression and knockdown experiments were performed to investigate the association between HDAC8 and matrix metalloproteinase 12 (MMP12). Results: YAK577 treatment restored ISO-induced reduction in LV fractional shortening and ejection fraction (n=9–11). YAK577 significantly downregulated cardiac hypertrophy marker genes (natriuretic peptide B, NPPB, and myosin heavy chain 7, MYH7) and cardiomyocyte size in vitro but not in vivo. YAK577 ameliorated cardiac fibrosis and fibrosis-related genes in vivo and in vitro. Additionally, YAK577 reduced elevated HDAC8 and MMP12 mRNA and protein expressions in ISO-infused mice, H9c2 cells, and rat neonatal cardiomyocytes.HDAC8 overexpression stimulated MMP12 and NPPB mRNA levels, while HDAC8 knockdown downregulated these genes. Conclusions YAK577 acts as a novel heart failure drug through the HDAC8/MMP12 pathway.

Objective: This study aimed to explore the correlation between balance function and core muscle activation in patients with adolescent idiopathic scoliosis (AIS), compared to healthy individuals. Methods: A total of 24 AIS patients and 25 healthy controls were recruited. The limits of stability (LOS) test were conducted to assess balance function, while surface electromyography was used to measure the activity of core muscles, including the internal oblique, external oblique, and multifidus. Diaphragm thickness was measured using ultrasound during different postural tasks. Center of pressure (COP) displacement and trunk inclination distance were also recorded during the LOS test. Results: AIS patients showed significantly greater activation of superficial core muscles, such as the internal and external oblique muscles, compared to the control group (p < 0.05). Diaphragm activation was lower in AIS patients during balance tasks (p < 0.01). Although no significant difference was observed in COP displacement between the groups, trunk inclination was significantly greater in the AIS group during certain tasks (p < 0.05). Conclusion These findings suggest distinct postural control patterns in AIS patients, highlighting the importance of targeted interventions to improve balance and core muscle function in this population.

Background Injury poses a serious threat to human health. As global warming continues to intensify, there is an urgent need to explore the impact of temperature changes on injury deaths. However limited research has focused on this issue. Objective To investigate the relationship between daily mean temperature change (Tm) and injury death, as well as to estimate the associated future death burden in Hunan Province. Methods We employed an individual-level, time-stratified case-crossing design to establish a conditional logistic regression model to analyze the exposure-response relationship between daily mean temperature change and injury death in Hunan Province from 2013 to 2018. Consequently, we conducted subgroup analysis of gender, age group, and injury type. Finally, we estimated the excess burden of injury death attributable to temperature changes under a sustainable development path [low emission scenario (SSP1-2.6)], regional competition path [high emission scenario (SSP3-7.0)], or fossil fuel development path [very high emission scenario (SSP5-8.5)]. Results The study collected 155577 injury deaths in Hunan Province. The results indicated that for each 1 ℃ increment in daily mean temperature, the cumulative excess risk (CER) of injury mortality among Hunan residents increased by 0.71% (95%CI: 0.53%, 0.90%). Notably, the CER for intentional injuries (1.06%, 95%CI: 0.51%, 1.61%) was higher than that for unintentional injuries (0.66%, 95%CI: 0.46%, 0.87%). Warmer temperatures were positively associated with CER of mortality due to drowning, falls, transport injuries, assaults, and suicides, while they were negatively associated with mortality due to poisoning. Compared with 2010–2019, for 2090–2099, the excess mortality rate (EMR) due to ambient temperature increase in Hunan Province under the SSP5-8.5 scenario (14.62/100000, 95%CI: 10.81/100000, 18.40/100000) would be higher than that of the SSP3-7.0 scenario (10.28/100000, 95%CI: 7.58/100000, 12.97/100000) and the SSP1-2.6 scenario (3.35/100000, 95%CI: 2.46/100000, 4.23/100000); the EMR would be around 2.5 times among men (20.64/100000, 95%CI: 14.44/100000, 26.8/100000) than that among women (8.33/100000, 95%CI: 3.98/100000, 12.6/100000). Among unintentional injuries, the leading contributors to EMR would be drowning (4.46/100000), falls (3.96/100000), and transport injuries (2.96/100000). And among intentional injuries, the EMR for suicide (2.08/100000) would be higher than that for assault (0.47/100000). Conclusion Climate warming will increase the total burden of injury-related deaths among residents in Hunan Province, especially in the absence of effective mitigation strategies and measures. It is necessary to strengthen the prevention and control of severe injuries closely related to temperature changes, such as drowning, falls, traffic, and suicides injuries, in order to reduce injury deaths associated with climate change.

AIM: To analyze the clinical features and multimodal imaging features of peripapillary hyper-reflective ovoid mass-like structure(PHOMS).METHODS: Retrospective observation study. Totally 35 patients(56 eyes)with PHOMS that diagnosed in the Affiliated Eye Hospital of Nanjing Medical University from January 2020 to March 2024 were included in the study. All patients underwent fundus photography, fundus fluorescein angiography, fundus autofluorescence, optical coherence tomography, and B-ultrasound.RESULTS:PHOMS occurred across diverse age groups, with an insidious onset often detected incidentally during routine ophthalmic examinations. More patients came to hospital for refractive errors due to blurred vision The boundary of the optic disc is blurred on fundus photography, and the nasal eminence is more significant, showing a “C” shaped halo. No obvious abnormal fluorescence was observed on fundus autofluorescence and fundus fluorescein angiography during different periods. An elevated appearance in vary degrees with more prominent in the nasal parts was showed on different OCT scans. Vertical scanning on the nasal side of the optic disc showed the best PHOMS structure, which could be seen under the retinal nerve fiber layer and on the Bruch membrane, with sharply marginated hyper-reflective ovoid mass-like structures, and no shielding effect on the choroid. The higher the elevation, the larger the volume. Ocular B-mode ultrasound showed a pre-optic disc bulge on the posterior wall of the eyeball, and there was no strong signal echo in it.CONCLUSION:PHOMS can be found frequently in myopic patients and often asymptomatic. Transient vision loss and floaters may occur in symptomatic cases. The most typical OCT feature is a nasally located hyper-reflective ovoid structure with distinct margins.

The major histocompatibility complex plays a crucial role in the immune response process, which is closely related to the occurrence and development of tumors and organ transplantation. Cellular immunity occupies an important position in tumor immunity and organ transplantation immunity, while humoral immunity also plays a significant role in organ transplantation immunity. Organ transplantation requires the induction and maintenance of immune tolerance, while tumors develop immune escape phenomena during their progression. In-depth exploration and comparison of the mechanisms of tumor immune escape and organ transplantation immune tolerance are of great significance for formulating reasonable immune tolerance induction strategies, improving the quality of life and prolonging the survival time of organ transplant patients.

The etiology of tumors is complex and influenced by multiple factors, including the host and environmental conditions. Allergy is primarily driven by the immune response of helper T cell 2 (Th2). Research has shown that the Th2 immune response is closely related to tumors, which is specifically manifested through Th2 antibodies, allergy-related effector cells and mediators within the tumors, as well as tumor immune-related functions. This internal interaction mechanism will increase the complexity and challenges associated with the clinical diagnosis and treatment of tumors and allergy. The formation of allergic constitution is shaped by both congenital and acquired factors, and its physical state is closely linked to the occurrence and progression of allergic diseases. Therefore, this paper aims to explore the relationship between tumors and allergic reactions from the perspective of traditional Chinese medicine (TCM) constitution theory. Based on the four basic principles of the TCM constitution, including endowment inheritance theory, environment constraint theory, body-spirit composition theory, and life process theory, this exploration will focus on four aspects: genetic factors and internal disease causes, inflammatory environments and functional regulation, psychological disorders and emotional pathogenesis, as well as age structure and disease risk. Furthermore, from the perspective of constitution-disease relation of chronic disease prevention, this paper will discuss the significant importance of adjusting allergic constitution to improve both subjective symptoms and objective indicators of allergic reactions in tumor patients.

Objective To assess and understand the service capabilities and existing problems of radiation health technical service institutions in Jiangsu Province, China, and provide a basis for improving in-process and post-process supervision as well as enhancing radiation health technical service capabilities. Methods Thirty radiation health technical service institutions in Jiangsu Province were selected as quality monitoring objects from the National Occupational Health Technical Service Institution Management Information System. Evaluations were conducted using a standardized national assessment checklist, and a comprehensive risk assessment was performed by combining the results of laboratory test capability comparisons. Results The 30 institutions all passed the quality monitoring, with an average score of （76.62 ± 5.07）. Comprehensive risk assessment identified 8 (26.67%) high-risk institutions, 22 (73.33%) medium-risk institutions, and 0 (0%) low-risk institutions. Conclusion The overall service quality of radiation health technical service institutions in Jiangsu Province is acceptable. However, further training and supervision are needed to improve technical service capacity and reduce service risks.

Objective To examine the current status and trends of colorectal cancer (CRC) burden among Chinese residents from 1990 to 2021. Methods Data on CRC burden in China, Asia, and the global population from 1990 to 2021 were retrieved from the Global Burden of Disease database for descriptive analysis. An age-period-cohort model was employed to estimate the effects of age, period, and cohort on CRC mortality and to forecast changes in disease burden. Results In 2021, China’s age-standardized mortality rate, prevalence rate, and DALY rate for CRC were higher than global and Asian averages. The estimated annual percentage changes (EAPC) from 1990 to 2021 were −0.49% (95%CI: −0.55% to −0.43%) for mortality, 3.17% (95%CI: 3.03%−3.31%) for prevalence, and −0.62% (95%CI: −0.71% to −0.54%) for DALYs. Areas with high and medium-high sociodemographic indexes (SDIs) showed significant decreases in standardized mortality and DALY rates, but these rates remained higher compared with other regions. CRC mortality increased with age in the Chinese population, more prominently in males than in females. Using the 2002–2006 period as a reference (RR=1), the period effect on CRC mortality risk for women was higher than that for men until 2004, after which it declined considerably. With the 1957 birth cohort as a reference (RR=1), CRC mortality risk generally decreased across subsequent birth cohorts. Predictions indicate that by 2035, the standardized prevalence rate will be 267.21 per 100 000, and the standardized mortality rate will be 12.29 per 100 000. Conclusion From 1990 to 2021, China’s age-standardized CRC mortality and DALY rates have decreased, while the standardized prevalence rate has increased. These findings suggest the government to establish a comprehensive multi-level CRC prevention network.
