Objective To understand the epidemiological characteristics and current status of pertussis in Jingzhou City from 2013 to 2024. Methods Data on reported pertussis cases in Jingzhou City (2013–2024) and hospitalized pertussis cases from two medical institutions (January–May 2024) were collected for descriptive epidemiological analysis. Results A total of 1 553 pertussis cases were reported in Jingzhou City from 2013 to 2024. The average annual incidence rate from 2013 to 2023 was 0.12/100 000, and that in 2024 was 28.86/100 000. The incidence peaked in spring and summer. High-incidence areas included Jingzhou District, Shashi District, and Jiangling County. There was no difference between men and women. The highest incidence occurred in the 0-year-old group, primarily among students, scattered children, and childcare attendees. Hospitalized cases exhibited milder and atypical symptoms. Age>2 months, and admission for treatment at the first visit were the protective factors for severe pertussis, while having a history of patent foramen ovale was the risk factor for severe pertussis. Conclusion Jingzhou City experienced a rapid and significant rise in pertussis incidence in 2024. Prevention and control measures in childcare facilities and schools should be prioritized during spring and summer. Enhancing laboratory testing in medical institutions can facilitate early diagnosis and treatment. Adjusting vaccination strategies for young infants and older children is critical to reducing both incidence and severe case rates.

Platelets play a crucial role in hemostasis and thrombosis. They have a complex and active metabolic system, particularly regarding lipid metabolism. The active and intricate lipid metabolism within platelets plays a central role in platelet activation, signal transduction, and functional regulation, making it crucial for studying the pathophysiological mechanisms of diseases. The platelet membrane structure is highly complex and it contains various lipids, including phospholipids, sphingolipids, cholesteryl esters, and triglycerides, etc. Current research has elucidated multiple metabolic pathways in platelets, such as phospholipid and sphingolipid metabolism, which profoundly influence platelet aggregation, release, and inflammatory responses. Upon activation, platelets release various lipids that interact with inflammatory cells in a paracrine manner. This review systematically describes the key lipid metabolism in platelets and its dynamic functional regulation. Lipid metabolism regulates processes such as platelet production, aging, and activation. This review emphasizes the interaction between lipid droplets and mitochondria, which is closely related to platelet activation. For instance, platelet-derived extracellular vesicles can transfer dysfunctional mitochondria from platelets to hepatocytes, leading to the dysfunction of lipid droplet-bound mitochondria and abnormal lipid droplet metabolism, thereby affecting hepatic lipid metabolism. The review summarizes interactions between platelet lipid metabolism and other cells, including leukocytes, erythrocytes, and lymphocytes. However, there are few studies on the interactions between platelets and cells through lipid metabolism, and the direct evidence is scarce. Further research is recommended in the future. It further explores the relationships between platelet lipid metabolism and the reproductive system, musculoskeletal system, the central nervous system, and the gut microbiota. Additionally, it reviews the close associations between platelet lipid metabolism and diseases such as diabetes, metabolic dysfunction-associated steatotic liver disease, immune thrombocytopenia, metabolic syndrome, and thrombotic disorders (thromboembolic diseases). For example, antiphospholipid syndrome (APS), typically characterized by reproductive impairment, may be associated with enhanced platelet activation and elevated phospholipase A2 activity in patients with APS. Moreover, lipid metabolism in the bone marrow microenvironment can promote platelet production. Under cellular stress, platelets transfer mitochondria to macrophages; in the spinal cord injury model, this process can regulate energy and lipid metabolism, leading to nerve and myelin regeneration and ultimately promoting the recovery of motor function. These findings indicate that modulating energy and lipid metabolism can influence platelet function, suggesting that targeting platelet lipid metabolism may provide a direction for disease treatment. Furthermore, the review covers the research on platelet lipid metabolism and related drugs, including traditional Chinese medicines and natural products. As the first selective 12-lipoxygenase (12-LOX) inhibitor to enter clinical trials, ML355 will facilitate future research on the biology of 12-LOX and its effects on regulation of platelet activity, hemostasis, and thrombosis, and promote the discovery of structure-based drugs. However, research on platelets and lipid metabolism still faces numerous challenges. For example, lipid droplet-mitochondria interaction in the liver regulates lipid metabolism. Meanwhile, there is controversy over whether autophagy serves a protective function or promotes the occurrence of liver disease. It is speculated that the interaction between mitochondrial autophagy and lipid droplets may be a future research direction. The precise regulatory mechanism of lipid metabolism and how to develop novel antithrombotic and anti-inflammatory drugs with high specificity and low side effects by targeting lipid metabolism remain current challenges. In summary, this review provides a comprehensive overview of platelet lipid metabolism, its interactions with other cells, and its roles in organ function and diseases. This contributes to the discovery of new disease-specific lipid biomarkers and drug targets. Future research could focus on structural modifications of drugs targeting lipid metabolism to enhance selectivity, offering directions for improving safety and efficacy, and developing the most effective individualized treatment plans for patients.

Objective:
To examine the association of sleep duration, physical activity, and their joint effects on depressive and anxiety symptoms among college students, and to provide evidence for the prevention and intervention of emotional symptoms in the population.
Methods:
From October to December 2023, a total of 7 684 college students aged 18-22 years, who were selected from nine universities in Hubei, Jiangxi, and Anhui provinces by using convenience sampling, underwent questionnaire surveys and physical examinations. Chi-square test and Logistic regression model were used to analyze the associations of meeting sleep duration and moderate to vigorous physical activity (MVPA) recommendations, as well as their joint effects, with depressive and anxiety symptoms.
Results:
The prevalence rates of depressive and anxiety symptoms were 25.78% and 35.59%, respectively. The prevalence rates of both depressive and anxiety symptoms differed significantly across sleep duration and physical activity groups ( χ 2= 9.32 -127.01, all P <0.01). Logistic regression analyses showed that insufficient sleep duration and failure to meet the physical activity recommendation were associated with higher odds of depressive symptoms ( OR =1.67, 1.20) and anxiety symptoms ( OR = 1.74 , 1.21 ) (all P <0.01). Further joint effects analyses showed that the combination of insufficient sleep and insufficient MVPA and that of insufficient sleep and sufficient MVPA were associated with higher odds of depressive symptoms ( OR =1.94, 1.38 ) and anxiety symptoms ( OR =2.09, 1.59) (all P <0.05). The combination of sufficient sleep and insufficient MVPA was also associated with higher odds of anxiety symptoms ( OR =1.16, P <0.05).
Conclusions
Sleep duration, physical activity, and their joint effects are associated with depressive and anxiety symptoms among college students. Joint interventions targeting both sleep and physical activity should be emphasized to reduce the risk of emotional symptoms.

Alzheimer’s disease (AD) is a neurodegenerative disorder characterized by progressive cognitive decline, functional impairment, and neuropsychiatric symptoms. It represents the most prevalent form of dementia among the elderly population. Accumulating evidence indicates that oxidative stress plays a pivotal role in the pathogenesis of AD. Notably, elevated levels of oxidative stress have been observed in the brains of AD patients, where excessive reactive oxygen species (ROS) can cause extensive damage to lipids, proteins, and DNA, ultimately compromising neuronal structure and function. Amyloid β‑protein (Aβ) has been shown to induce mitochondrial dysfunction and calcium overload, thereby promoting the generation of ROS. This, in turn, exacerbates Aβ aggregation and enhances tau phosphorylation, leading to the formation of two pathological features of AD: extracellular Aβ plaque deposition and intracellular neurofibrillary tangles (NFTs). These events ultimately culminate in neuronal death, forming a vicious cycle. The interplay between oxidative stress and these pathological processes constitutes a core link in the pathogenesis of AD. The signaling pathways mediating oxidative stress in AD include Nrf2, RCAN1, PP2A, CREB, Notch1, NF‑κB, ApoE, and ferroptosis. Nrf2 signaling pathway serves as a key regulator of cellular redox homeostasis, exerts important antioxidant capacity and protective effects in AD. RCAN1 signaling pathway, as a calcineurin inhibitor, and modulates AD progression through multiple mechanisms. PP2A signaling pathway is involved in regulating tau phosphorylation and neuroinflammation processes. CREB signaling pathway contributes to neuroplasticity and memory formation; activation of CREB improves cognitive function and reduce oxidative stress. Notch1 signaling pathway regulates neuronal development and memory, participates in modulation of Aβ production, and interacts with Nrf2 toco-regulate antioxidant activity. NF‑κB signaling pathway governs immune and inflammatory responses; sustained activation of this pathway forms “inflammatory memory”, thereby exacerbating AD pathology. ApoE signaling pathway is associated with lipid metabolism; among its isoforms, ApoE-ε4 significantly increases the risk of AD, leading to elevated oxidative stress, abnormal lipid metabolism, and neuroinflammation. The ferroptosis signaling pathway is driven by iron-dependent lipid peroxidation, and the subsequent release of lipid peroxidation products and ROS exacerbate oxidative stress and neuronal damage. These interconnected pathways form a complex regulatory network that regulates the progression of AD through oxidative stress and related pathological cascades. In terms of therapeutic strategies targeting oxidative stress, among the drugs currently used in clinical practice for AD treatment, memantine and donepezil demonstrate significant therapeutic efficacy and can improve the level of oxidative stress in AD patients. Some compounds with antioxidant effects (such asα-lipoic acid and melatonin) have shown certain potential in AD treatment research and can be used as dietary supplements to ameliorate AD symptoms. In addition, non-drug interventions such as calorie restriction and exercise have been proven to exerted neuroprotective effects and have a positive effect on the treatment of AD. By comprehensively utilizing the therapeutic characteristics of different signaling pathways, it is expected that more comprehensive multi-target combination therapy regimens and combined nanomolecular delivery systems will be developed in the future to bypass the blood-brain barrier, providing more effective therapeutic strategies for AD.

International Eye Science 2025;25(12):1958-1964
Primary open angle glaucoma(POAG)is a chronic, progressive optic neuropathy characterized by pathologically elevated intraocular pressure(IOP), which is the main high-risk factor, although the etiology is still unclear. Due to the insidious onset, many patients are already in the intermediate or advanced stages at the first presentation. At these stages, optic nerve damage is often severe, the target IOP requirement is stringent(below 12 mmHg), with poor tolerance to treatment, which necessitates comprehensive treatment approaches to control disease progression. This review systematically summarizes recent advances in the clinical management of advanced POAG, including medications, laser therapy, trabeculectomy, glaucoma drainage device implantation, minimally invasive glaucoma surgery and other emerging therapies. It elaborates on the mechanisms of action, efficacy, safety, suitable populations, and indications for switching treatments. Incorporating the latest clinical research data up to 2025, the analysis evaluates the impact of different treatment approaches on clinical practice and explores the future development trends, aiming to provide comprehensive references for individualized treatment strategies to maximize preservation of visual function in patients with advanced POAG.

This study investigated the role of the nuclear factor of activated T cells c3 (NFATc3) in vascular smooth muscle cells (VSMCs) during aortic aneurysm and dissection (AAD) progression and the underlying molecular mechanisms. Cytoplasmic and nuclear NFATc3 levels were elevated in human and mouse AAD. VSMC-NFATc3 deletion reduced thoracic AAD (TAAD) and abdominal aortic aneurysm (AAA) progression in mice, contrary to VSMC-NFATc3 overexpression. VSMC-NFATc3 deletion reduced extracellular matrix (ECM) degradation and maintained the VSMC contractile phenotype. Nuclear NFATc3 targeted and transcriptionally upregulated matrix metalloproteinase 9 (MMP9) and MMP2, promoting ECM degradation and AAD development. NFATc3 promoted VSMC phenotypic switching by binding to eukaryotic elongation factor 2 (eEF2) and inhibiting its phosphorylation in the VSMC cytoplasm. Restoring eEF2 reversed the beneficial effects in VSMC-specific NFATc3-knockout mice. Cabamiquine-targets eEF2 and inhibits protein synthesis-inhibited AAD development and progression in VSMC-NFATc3-overexpressing mice. VSMC-NFATc3 promoted VSMC switch and ECM degradation while exacerbating AAD development, making it a novel potential therapeutic target for preventing and treating AAD.

Objective To evaluate the molluscicidal effect of spraying different formulations of niclosamide ethanolamine salt with drones against Oncomelania hupensis in ditches. Methods A semi-dry and semi-wet ditch with O. hupensis snails was selected in the second branch field of Jiangbei Farm, Jiangling County, Hubei Province in May 2023, and divided into 4 experimental areas, named groups A1, A2, B1 and B2. Environmental cleaning was performed in groups A1 and B2, and was not conducted in groups A2 or B2. Then, 50% wettable powder of niclosamide ethanolamine salt was sprayed with drones at an effective dose of 2 g/m2 in groups A1 and A2, and 5% niclosamide ethanolamine salt granule was sprayed with drones at an effective dose of 2 g/m2 in groups B1 and B2. O. hupensis snails were surveyed using the systematic sampling method 1, 3, 5, 7, 14 days after spraying, and the natural mortality and corrected mortality of O. hupensis snails were calculated. Results The occurrence of frames with living snails, mean density of living snails and natural mortality of snails were 97.50% (117/120), 6.30 snails/0.1 m2 and 1.18% (9/765) in the test ditch before spraying, respectively. There were significant differences in the mortality of snails among four groups 1, 3, 5, 7 and 14 days after spraying niclosamide formulations with drones (χ2 = 17.230, 51.707, 65.184, 204.050 and 34.435, all P values < 0.01). The overall mortality rates of snails were 94.51% (1 051/1 112), 79.44% (908/1 143), 96.54% (977/1 012) and 88.55% (1 021/1 153) in groups A1, A2, B1 and B2 (χ2 = 207.773, P < 0.05), respectively. In addition, there was no significant difference in the overall snail mortality between groups A1 and B1 (P > 0.05), and the snail mortality in groups A1 and B1 were both statistically different from that in groups A2 and B2 (all P values < 0.05). Conclusion Both 50% wettlable powder of niclosamide ethanolamine salt and 5% niclosamide ethanolamine salt granule sprayed with drones are active against O. hupensis snails in ditches, and environmental cleaning may improve the molluscicidal effect.

Objective:
To explore the association of milk tea consumption with comorbid of overweight/obesity and depressive symptoms among college students, so as to provide a reference for promoting the physical and mental health of college students.
Methods:
A questionnaire survey was conducted from August to October 2023 using convenience sampling among 13 920 students from nine universities in Shanghai, Jiangxi, and Hubei provinces (municipality directly under the central government). Information on college students demographic characteristics, milk tea consumption, overweight/obesity status, and depressive symptoms was collected. Chi square tests were used to compare the association between different demographic characteristics and milk tea consumption with comorbid overweight/obesity and depressive symptoms. Multivariate Logistic regression analysis was performed to infer the strength of the association.
Results:
The detection rate of comorbidity of overweight/obesity and depressive symptoms was 5.8% among college students. The univariate analysis revealed statistically significant differences in the detection rate of comorbidity of overweight/obesity and depressive symptoms among various groups, including gender, grade, parents education level, only child status, family economic status, meeting moderate to high levels of physical activity standards, sleep quality, and frequent fast food consumption ( χ 2= 82.10, 23.07, 8.91, 10.87 , 4.56, 47.60, 17.60, 386.74, 96.61, P <0.05). There were also statistically significant differences between groups based on milk tea consumption frequency and quantity ( χ 2=42.12, 38.76, P <0.01). Compared with the group of without consuming milk tea, Logistic regression analysis showed that college students who consumed milk tea 4-5 times and ≥6 times had higher risk of comorbid overweight/obesity and depressive symptoms ( OR =1.98, 2.46), and college students who consumed 1-1 500 mL and ≥3 000 mL of milk tea also had higher comorbidity risk ( OR =1.52, 1.22) ( P <0.05).
Conclusions
Frequent and excessive milk tea consumption among college students may increase the risk of comorbid of overweight/obesity and depressive symptoms. It is recommended to reduce the frequency and quantity of milk tea consumption to improve college students physical and mental health.
