Methods Duing July 2024, a survey on the mosquito diversity was conducted at the Manzhouli Port. Captured mosquitoes and their ectoparasites were identified to species level. Results A total of 1840 adult mosquitoes were collected, representing species from three genera: Culex(Cx. modestus, Cx. pipiens pallens), Aedes(Ae. dorsalis, Ae. flavidorsalis, Ae. flavescens), and Anopheles (An. messeae). Among all the mosqutioes specimens,3 out of 150 captured An. messeae were found to carry ectoparasitic mites, with number of 2,4,27 mites separately. Morphological and molecular identification reached the same result as water mites(Hydrachnidiae, Hydracrina). COI gene sequence showed 94% similarity with the closest species Arrenurus truncatellus. Conlusions Literature review suggests water mites are host-specific parasitism of mosquito species and herein with the first record of Arrenurus sp. parasiting on An. Messeae in the most high-latitude region globally.

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 explore the method for establishing a pig left lung orthotopic transplantation model. Methods A total of 4 male Yorkshire pigs weighing (40.0±2.5) kg underwent surgical procedures, including anesthesia, tracheal intubation, donor lung procurement, and recipient lung transplantation. Histological morphology and blood gas analysis of the transplanted lungs were assessed 2 hours after reperfusion to evaluate the histological changes and function of the transplanted lungs. Results The pigs underwent left lung in situ transplantation, effectively simulating conditions relevant to human lung transplantation. Two hours after the transplantation, arterial blood gas analysis showed that arterial partial pressure of oxygen was 155.4-178.6 mm Hg, arterial partial pressure of carbon dioxide was 53.1-62.4 mm Hg, and the oxygenation index was 310.8-357.2 mm Hg. Hematoxylin and eosin staining indicated a low degree of pulmonary edema and minimal cellular infiltration. Conclusion The pig left lung orthotopic transplantation model possesses strong operability and stability. Researchers can replicate this model according to the described methods and further conduct basic research and explore clinical translational applications.

Abstract To clarify the service targets, service contents, and safeguard mechanisms of the basic public service program for student vision health management, the study grounded in the current status of child and adolescent myopia prevention and control in China and integrated with the practical experience and innovative practices of Wuhan National Demonstration Area for Student Vision Health Management, takes education as the main thread and schools as the base, consolidating resources from multiple stakeholders including education administrative departments, schools, families, and professional technical service institutions. Centering on four core components—vision health education, monitoring and record keeping, risk prevention and control, and dynamic management, the study constructs a multi tiered basic public service system for vision health management of primary and secondary school students. It further proposes the use of an intelligent management platform and a "three tier color coded early warning" mechanism (red, yellow, blue) to prevent and control student myopia at the source, providing schools with replicable and operable implementation pathways to enhance the level of student vision health management.

Lung cancer constitutes the most prevalent and lethal malignant tumor in China. Approximately 85% of lung cancer diagnoses correspond to the non-small cell histological subtype [non-small cell lung cancer (NSCLC)]. Despite surgery being the mainstay for early-stage disease, postoperative recurrence remains high and adjuvant chemotherapy offers limited benefit. In recent years, targeted therapy has demonstrated substantial advantages in driver mutation-positive NSCLC. To this end, the Lung Cancer Medical Education Committee of the Chinese Medical Education Association developed guidelines based on a systematic review of evidence through November 2025, using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach and a modified Delphi method. Focusing on epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK), and addressing ROS proto-oncogene 1 (ROS1), B-Raf proto-oncogene serine/threonine kinase (BRAF) V600E mutation, and mesenchymal-epithelial transition factor (MET) exon 14 (METex14) skipping, the guideline covers molecular testing, neoadjuvant/adjuvant therapy, perioperative strategies, minimal residual disease monitoring, and postoperative surveillance. It defines testing requirements, specifies stage-directed and subtype-specific treatments, and standardizes minimal residual disease monitoring. These recommendations emphasize precision and feasibility to improve survival and quality of life.

ObjectiveAutism spectrum disorder (ASD) is a neurodevelopmental condition characterized by difficulties with communication and social interaction, restricted and repetitive behaviors. Previous studies have indicated that individuals with ASD exhibit early and lifelong attention deficits, which are closely related to the core symptoms of ASD. Basic visual attention processes may provide a critical foundation for their social communication and interaction abilities. Therefore, this study explores the behavior of children with ASD in capturing attention to changes in topological properties. MethodsOur study recruited twenty-seven ASD children diagnosed by professional clinicians according to DSM-5 and twenty-eight typically developing (TD) age-matched controls. In an attention capture task, we recorded the saccadic behaviors of children with ASD and TD in response to topological change (TC) and non-topological change (nTC) stimuli. Saccadic reaction time (SRT), visual search time (VS), and first fixation dwell time (FFDT) were used as indicators of attentional bias. Pearson correlation tests between the clinical assessment scales and attentional bias were conducted. ResultsThis study found that TD children had significantly faster SRT (P<0.05) and VS (P<0.05) for the TC stimuli compared to the nTC stimuli, while the children with ASD did not exhibit significant differences in either measure (P>0.05). Additionally, ASD children demonstrated significantly less attention towards the TC targets (measured by FFDT), in comparison to TD children (P<0.05). Furthermore, ASD children exhibited a significant negative linear correlation between their attentional bias (measured by VS) and their scores on the compulsive subscale (P<0.05). ConclusionThe results suggest that children with ASD have difficulty shifting their attention to objects with topological changes during change detection. This atypical attention may affect the child’s cognitive and behavioral development, thereby impacting their social communication and interaction. In sum, our findings indicate that difficulties in attentional capture by TC may be a key feature of ASD.

To provide scientific, systematic, and standardized weight management guidance for overweight and obese children and adolescents, the study focuses on the core concept of healthy lifestyle intervention, integrates multidisciplinary expert opinions and research findings,and proposes a comprehensive multidisciplinary intervention framework covering scientific exercise intervention, precise nutrition and diet, optimized sleep management, and standardized psychological support. It calls for the establishment of a multi agent collaborative management mechanism led by the government, implemented by families, fostered by schools, initiated by individuals, optimized by communities, reinforced by healthcare, and coordinated by multiple stakeholders. Emphasizing a child and adolescent centered approach, the consensus advocates for comprehensive, multi level, and personalized guidance strategies to promote the internalization and maintenance of a healthy lifestyle. It serves as a reference and provides recommendations for the effective prevention and control of overweight and obesity, and enhancing the health level of children and adolescents.

Objective:To investigate the mid-term efficacy of Pulsar-18 stent in the treatment of spontaneous isolated superior mesen-teric artery dissection(SIDSMA)through a retrospective analysis.Methods:A retrospective analysis was performed for the data of pa-tients with SIDSMA who received treatment with Pulsar-18 stent from April 2019 to March 2021.Basic information was collected,such as sex,age,underlying disease,and radiological features,and the patients were observed in terms of the improvement in clinical symp-toms,stent patency rate,and vascular remodeling during follow-up.Results:A total of 45 patients were included in this study,with 41 male patients and 4 female patients.The patients had an age of 45-72 years,and the patients with hypertension accounted for 48.89%(22/45).The surgical success rate was 100%.A total of 63 stents were placed for the 45 patients,with a stent diameter ranging from 5 mm to 7 mm.There were no perioperative complications such as acute thrombosis of the stent,and the probability of hematoma at the puncture point was 0%.The stent patency rate was 100%at 3 months,6 months,1 year,and 2 years after stent placement,and the com-plete vascular remodeling rate was 64.4%,82.2%,82.2%,and 86.7%,respectively.One patient developed bloody stool at 5 months af-ter surgery and was diagnosed with duodenal ulcer,and the patient fully recovered after endoscopic hemostasis.The other patients had no recurrent abdominal pain,new-onset aneurysms,or enlargement of the false lumen within 2 years.Conclusion:Pulsar-18 stent placement is an effective treatment method for SIDSMA and can provide a high rate of complete vascular remodeling,with a high pa-tency rate during mid-term follow-up.

Objective To investigate the effect and mechanism of dexmedetomidine(Dex)pretreated pericytes(Dex-PCs)on acute lung injury(ALI)in septic mice.Methods Mouse model of sepsis-ALI was established with intraperitoneal injection of lipopolysaccharide(LPS)at a dose of 10 mg/kg.A total of 96 C57BL/6J mice were randomly divided into sham operation(Sham)group,ALI group,PC treatment group and Dex-PCs treatment group.The mice of the PCs and Dex-PCs groups received a tail venous injection of 5×105 PC cells,respectively,whereas those of the Sham and ALI groups received equal volume of normal saline.Flow cytometry,immunofluorescence assay,whole-body volume tracing system and ELISA were used to observe the changes in the colonization of PCs,pulmonary vascular permeability,lung function,serum TNF-α and IL-6 levels,as well as the survival rate and survival time of mice at 72 h after LPS stimulation.After PCs and Dex-PCs were exposed to 10 μg/mL LPS,the level of intracellular reactive oxygen species(ROS)was measured.Results Compared with the Sham group,the ALI group had increased permeability of pulmonary vascular endothelial cells,extensive extravasation of Evans blue,severely destructed of lung tissue structure and massive inflammatory cell infiltration,higher lung wet/dry weight ratio,elevated serum TNF-α and IL-6 levels,and declined lung function,and no mice survived for 72 h after modeling(P＜0.05).Both PC cell treatment effectively alleviated the pulmonary vascular endothelial leakage,reduced Evans blue content per unit tissue,improved lung pathological structure,lung function and inflammatory responses,and significantly improved the survival rates in the PC group and the Dex-PC group(P＜0.05).What's more,the therapeutic effect of Dex-PC cells was significantly better than that of the PC cells(P＜0.05).LPS stimulation induced ROS accumulation greatly in PCs,but no such effect was observed in the PCs after Dex pretreatment(P＜0.05).Conclusion Dex pretreatment significantly enhances PCs'protective effect on pulmonary vascular endothelial barrier functions in septic mice,which may be due to its enhancing anti-oxidative capacity of PCs.

Widespread utilization of glyphosate has led to environmental residues,posing potential threats to ecological systems and human health.Traditional methods for detection of glyphosate are limited by specialized equipment and operational techniques,resulting in inefficient responses.Therefore,it is urgent to develop a convenient,sensitive and accurate detection method for detection of glyphosate.Herein,a new naphthalenesulfonamide-based"Turn-on"fluorescent probe was synthesized using 2-chloroaniline and dansyl chloride as raw materials through a one-step process,which showed a good linear relationship between the glyphosate concentration in concentration range of 0.003-70 μmol/L and the fluorescence intensity(R2=0.995),with a detection limit of 2.73 nmol/L(S/N=3).Analytical techniques such as nuclear magnetic resonance(NMR)spectroscopy and high-resolution mass spectrometry(HRMS)were used to investigate the interaction mechanism between the fluorescent probe and glyphosate.The results indicated that a nucleophilic substitution reaction occurred between the probe and the secondary amine(—NH—)of glyphosate,inducing a photoinduced electron transfer(PET)effect which enhanced the fluorescence intensity by 11.2 times.The probe showed good anti-interference ability towards coexisting metal ions,anions and pesticides in water.When applied to determination of glyphosate in the samples such as tap water,river water(Xiangxi River Reservoir),soil,soybeans,and corn,the spiking recoveries ranged from 94.7％to 109.9％,demonstrating the high accuracy and broad applicability of this detection method.A portable test strip based on this fluorescent probe was developed for rapid semi-quantitative analysis of glyphosate.The developed method was rapid,sensitive,and portable,providing theoretical and technical support for on-site measurement of environmental contaminants.
