This review described the potential health threats to the cardiovascular system from micro-nano plastics (MNPs) and their multifaceted toxicity mechanisms. The article reviewed the environmental distribution of MNPs, exposure pathways, and their toxic effects on the cardiovascular system, and summarized the specific mechanisms of MNPs involving oxidative stress, inflammatory response, mitochondrial damage, apoptosis, pyroptosis, and autophagy dysregulation. Meanwhile, the combined toxic effects of MNPs with other environmental pollutants (e.g., heavy metals and polycyclic aromatic hydrocarbons), including synergistic, antagonistic, and dual effects, were analyzed, and the potential risks of MNPs as carriers of microorganisms and toxic chemicals were pointed out. The widespread presence of MNPs and their complex toxicity mechanisms may make them important triggers for cardiovascular diseases, but current research still suffers from unbalanced studies across environmental systems, incomplete understanding of plastic properties, and limited knowledge of long-term biological effects. Future research should focus on the long-term effects of MNPs, the joint toxicity mechanisms with other pollutants, and the differential effects across population subgroups. It is suggested to accelerate plastic recycling technology innovation, promote biodegradable materials, and optimize waste treatment process to mitigate the potential threat of MNPs pollution to human health. Through multidisciplinary collaboration and in-depth research, combining innovative concepts from toxicology, public health policy, and environmental science, it is expected to provide new methods and approaches for the prevention and treatment of cardiovascular diseases associated with MNPs.

OBJECTIVE: To analyze the acupoint selection patterns and core prescriptions of acupuncture for polycystic ovary syndrome (PCOS) using data mining, and to explore the molecular mechanisms of core acupoints through network acupuncture medicine. METHODS: The randomized controlled trials (RCTs) on acupuncture for PCOS published from January 1, 2004 to July 21, 2024 were retrieved from CNKI, VIP, Wanfang, PubMed, and Web of Science databases. R software (version 4.4.0) was used for acupoint frequency and association rule analysis to identify core acupoint prescriptions. Potential targets were predicted via the STITCH and Swiss Target Prediction databases, and a "core prescription-active compounds-targets- PCOS" network was constructed. Cytoscape 3.7.1 was applied to build protein-protein interaction (PPI) networks of potential targets of core acupoint prescriptions. Key therapeutic targets were subjected to gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) enrichment analyses using the DAVID and Microbioinformatics platforms. RESULTS: A total of 176 RCTs were included, covering 208 prescriptions and 89 acupoints. The five most frequently used acupoints were Guanyuan (CV4), Sanyinjiao (SP6), Zigong (EX-CA1), Zusanli (ST36) and Zhongji (CV3). Association rule analysis yielded 13 core acupoint combinations, with Guanyuan (CV4), Sanyinjiao (SP6), Zigong (EX-CA1) and Zusanli (ST36) as the core prescription. Twenty-seven active compounds were involved, with 852 potential therapeutic targets, among which 208 targets overlapped with PCOS-related targets. Network acupuncture medicine analysis suggested that the core prescription may act through targets such as estrogen receptor 1 (ESR1), proto-oncogene tyrosine-protein kinase Src (SRC), signal transducer and activator of transcription 3 (STAT3), peroxisome proliferator-activated receptor gamma (PPARG), and RAC-alpha serine/threonine-protein kinase (AKT1). GO and KEGG analyses indicated that the main pathways included the hypoxia-inducible factor 1 (HIF-1) signaling pathway, phosphatidylinositol 3-kinase-protein kinase B (PI3K-AKT) signaling pathway, and advanced glycation end products-receptor for advanced glycation end products (AGE-RAGE) signaling pathway, involving processes such as signal transduction, receptor complex formation, and cytokine activity. CONCLUSION The core acupoint prescription for PCOS might exert therapeutic effects through multiple targets and pathways, providing a theoretical basis for mechanistic research on acupoint prescriptions.

The incidence of cardiovascular diseases (CVD) together with their associated risk factors increasingly impact public health. According to the data provided in the 2024 Annual Report on Cardiovascular Health and Diseases in China, the crude incidence of cardiovascular and cerebrovascular diseases among Chinese residents aged ≥18 years, including acute myocardial infarction (AMI), angina pectoris treated by percutaneous transluminal coronary angioplasty/stent implantation and/or coronary artery bypass grafting, stroke, and sudden cardiac death was 620.33 per 100,000 population, with 87.6 for AMI. Stroke had an incidence of 491.0 per 100,000 population. The prevalence of adult coronary heart disease (CHD, aged ≥18 years) was 758 per 100,000 population. The CVD mortality in 2021 remained the highest, exceeding that of cancer and other causes. The crude mortality rate of CVD in 2021 was 364.16 per 100,000 population in rural areas and 305.39 per 100,000 population in urban areas. The crude mortality rates of cerebrovascular diseases and CHD among urban and rural residents in 2021 were 140.02 and 175.58, 135.08 and 148.19 per 100,000 population, respectively. In addition to interpreting the key findings of CVD incidence and mortality in China, we also update the data of associated risk factors, including tobacco use, physical activity, diet and nutrition, overweight and obesity, hypertension, dyslipidemia, diabetes, chronic kidney disease, sleep and psychological factors, environmental factors, and the diagnostic conditions of CVD diseases, aiming to provide a scientific foundation for advancing CVD prevention and control, and to inform relevant public health policy development.

OBJECTIVES: To analyze sex and age distribution of global disease burden of calcific aortic valve disease (CAVD) from 1990 to 2021. METHODS: CAVD data during 1990-2021 were obtained from the IHME website for Global Burden of Disease (GBD). The prevalence, mortality, years lived with disability (YLDs), and disability-adjusted life years (DALYs) were analyzed by gender and age groups. Joinpoint regression was used to calculate annual percentage change (APC) and average annual percentage change (AAPC). RESULTS: In 2021, there were 13.32 million CAVD patients and 142 000 deaths caused by CAVD globally. Age-standardized prevalence was higher in males (193.2/10⁵) than that in females (128.9/10⁵). Patients in 65-<85 age group accounted for 64.0% of total cases, while those ≥85 years old accounted for 16.1%. From 1990 to 2021, prevalence increased in both sexes with an AAPC of 0.72% for males and 0.57% for females, respectively. Prevalence grew fastest from 2000 to 2010, slowed thereafter, and declined from 2015 to 2021. In <65 years old, the mortality of males was 2.4 times higher than that of females, while in ≥85 years old, mortality of females (117.3/10⁵) exceeded that of males (99.1/10⁵). YLD rates increased with age, and were higher in males for all age groups. DALY rates decreased overall but increased in ≥85 years old, with a greater increase in females. CONCLUSIONS There are significant gender and age disparities in global disease burden of CAVD, with the elderly, especially super-elderly females deserving particular attention. It is recommended to develop personalized intervention strategies for these populations.

Amoenucles A-F (1-6), six previously undescribed nucleoside derivatives, and two known analogs (7 and 8) were isolated from the culture of Aspergillus amoenus TJ507. Their structures were elucidated through spectroscopic analysis, single-crystal X-ray crystallography, and chemical reactions. Notably, 3 and 4 represent the first reported instances of nucleosides with an attached pyrrole moiety. Of particular significance, the absolute configuration of the sugar moiety of 1-4 was determined using nuclear magnetic resonance (NMR), electric circular dichroism (ECD) calculations, and a hydrolysis reaction, presenting a potentially valuable method for confirming nucleoside structures. Furthermore, 1, 2, and 5-8 exhibited potential tumor necrosis factor α (TNF-α) inhibitory activities, which may provide a novel chemical template for the development of agents targeting autoimmune and inflammatory diseases.

Objective:To quantitatively detect plasma ceramide (Cer) levels using high-performance liquid chromatography tandem mass spectrometry (LC-MS/MS) and analyze plasma ceramide levels in homozygous familial hypercholesterolemia (HoFH) patients.Methods:A case-control study was conducted. Plasma samples were collected from 70 healthy individuals who underwent physical examinations at the Health Check-Up Center of Suzhou Municipal Hospital between October 2023 and December 2023, as well as from 34 HoFH patients (including 11 patients with concomitant coronary artery disease) who were treated in the Cardiology Department of the same hospital during the same period. Deuterated isotopes were used as internal standards, and a Phenomenex Kinetex C18 column (2.1×100 mm, 2.6 μm) was employed for separation. An LC-MS/MS method was developed using an AB Sciex 6500+triple quadrupole mass spectrometer for the detection of ceramides, followed by method validation. Additionally, the differences in ceramide levels among healthy individuals, HoFH patients, and HoFH patients with concomitant coronary artery disease were compared. Receiver operating characteristic (ROC) curves were used to evaluate the diagnostic value of various ceramides for HoFH.Results:A method for the quantification of 9 plasma ceramides was established, showing excellent linearity ( r>0.99), precision (1.8%-11.0%), and recovery rates (89.9%-114.7%), meeting the requirements for detection. Compared to the control group, the HoFH group exhibited significantly higher levels of Cer(d18∶1/14∶0), Cer(d18∶1/16∶0), Cer (d18∶1/18∶0), Cer (d18∶1/18∶1), Cer (d18∶1/20∶0), Cer(d18∶1/22∶0), Cer(d18∶1/24∶0), and Cer(d18∶1/24∶1) ( P<0.05). ROC curve analysis revealed that Cer(d18∶1/18∶0) had the highest diagnostic value for HoFH, with an area under the curve (AUC) of 0.83, a cutoff value of 64.6 ng/ml, and sensitivity and specificity of 82.4% and 87.1%, respectively. In HoFH patients complicated with coronary artery disease, the plasma ceramide levels of Cer(d18∶1/18∶0) [(155.7±25.1) ng/ml vs (103.0±11.1) ng/ml, P=0.03] and the ratio of Cer (d18∶1/18∶0) to Cer(d18∶1/24∶0) (0.077±0.012 vs 0.048±0.006, P=0.03) were significantly higher than in HoFH patients without coronary artery disease. Conclusion:A quantitative LC-MS/MS method was developed for detecting ceramides in human plasma, which shows potential diagnostic value for patients with HoFH.

With the increasing prevalence of unhealthy lifestyles among Chinese residents,the growing burden of cardiovascular risk factors,and the accelerating aging of the population,cardiovascular diseases(CVD)remain a major public health challenge that seriously threatens the health of Chinese residents.In 2023,the crude incidence rate of CVD among Chinese residents aged 18 and above was 620.33 per 100 000,with rates of 717.36 per 100 000 for men and 519.64 per 100 000 for women.The incidence rate of CVD increases significantly with age.Despite notable advancements in CVD diagnostic and therapeutic technologies in recent years,both the inci-dence and mortality rates continue to rise,indicating that the turning point for a reduction in the disease burden has not yet been reached.Drawing upon the latest data from the《China Cardiovascular Health and Disease Report 2024》,this article provides a systematic review of recent findings on the prevalence trends,risk factors,current status of diagnosis and treatment,research developments,and economic burden associated with CVD in China,with the aim of offering a scientific foundation for the development of effective prevention and control strategies.

Objective To compare the 12-month efficacy and safety of N-butyl cyanoacrylate (NBCA) versus radiofrequency ablation (RFA) in treating great saphenous vein (GSV) insufficiency. Methods A total of 155 patients with GSV insufficiency from five centers were randomly allocated to the NBCA group or RFA group. Postoperative efficacy and safety outcomes were evaluated. Results Immediate postoperative closure rates of the GSV trunk were 100% in both groups. The closure rates of NBCA and RFA group were 98.6% and 98.5% at 3 months, 97.1% and 98.5% at 6 months, 98.1% and 95.9% at 12 months, with no statistically significant differences (P>0.05). After treatment, CEAP classification improved significantly from baseline in both groups. In terms of safety, 1 case of phlebitis, 1 case of ablation-related thrombus extension (ARTE) and 2 cases of calf muscle venous thrombosis(CMVT) occurred in the NBCA group, while 2 cases of limb numbness, 1 case of persistent thigh pain and 2 cases of CMVT in the RFA group. All reported serious adverse events in both groups were assessed as unrelated to the medical device or the trial procedure. Conclusions NBCA demonstrates non-inferior efficacy and safety compared to RFA for treating GSV insufficiency over 12 months.

Objective:To study the relationship between the levels of multiple elements in urine and the risk of arsenic poisoning in populations exposed to drinking water arsenic in Inner Mongolia Autonomous Region (Inner Mongolia).Methods:From April 2023 to January 2024, a case-control study method was used to select 128 individuals with a residence time of ≥10 years in drinking water arsenic exposed areas in Inner Mongolia as study subjects. Eighty-one individuals diagnosed with arsenic poisoning were selected as the case group, and 47 healthy individuals were selected as the control group for urine sample collection and questionnaire survey. Inductively coupled plasma mass spectrometry was employed to determine the levels of 10 elements (chromium, manganese, cobalt, nickel, copper, zinc, arsenic, molybdenum, cadmium and lead) in urine. The levels of each element in urine were divided into four groups ( Q1, Q2, Q3, and Q4 groups) based on quartiles. The associations between the levels of various elements in urine and the risk of arsenic poisoning were studied using binary logistic regression model and restricted cubic spline (RCS). Results:The age of the control group and the case group [ M ( Q1, Q3)] were 61 (53, 69) and 61 (56, 67) years old, respectively. There were 19 and 43 males, and 28 and 38 females, respectively. There was no statistically significant differences in age and and gender composition between the two groups ( Z = - 0.39, P = 0.700; χ 2 = 1.91, P = 0.167). The levels of urinary copper and cadmium of the case group were higher than those of the control group, and the differences were statistically significant ( Z = - 2.66, - 2.16, P < 0.05). The results of univariate logistic regression analysis showed that urinary copper was an influencing factor for arsenic poisoning ( P = 0.017). The results of multivariate logistic regression analysis revealed that after adjusting for covariates, urinary copper and arsenic were independent influencing factors of arsenic poisoning ( P < 0.05). Taking Q1 group as a reference, urinary copper in Q3 group [ OR (95% CI) = 8.23 (1.81, 37.39), P = 0.006] increased the risk of arsenic poisoning, while urinary arsenic in Q2, Q3, and Q4 groups [ OR (95% CI) = 0.24 (0.06, 0.92), 0.12 (0.03, 0.53), 0.15 (0.04, 0.63), P < 0.05] decreased the risk of arsenic poisoning. After adjusting for covariates, RCS did not show a dose-response relationship between urinary copper, urinary arsenic, and arsenic poisoning ( P > 0.05). Conclusion:Urinary arsenic and copper are associated with the risk of arsenic poisoning in the drinking water arsenic exposed areas of Inner Mongolia, copper exposure may contribute significantly to arsenic poisoning.
