Lung transplantation is a definitive treatment for end-stage lung disease and can significantly improve patient prognosis. However, postoperative complications such as infection, rejection, ischemia-reperfusion injury and chronic lung allograft dysfunction intertwine to form a complex pathological network, posing persistent challenges to long-term patient survival. In 2025, research teams worldwide have made systematic progress in the field of basic lung transplantation research. By integrating cutting-edge technologies including single-cell multi-omics, spatial transcriptomics and novel animal models, significant breakthroughs have been achieved in the evolutionary dynamics of drug-resistant infections, molecular mechanisms of immune regulation, programmed cell death, optimization of donor lung protection strategies and early warning of chronic lung allograft dysfunction. This article systematically reviews the representative advances in basic lung transplantation research worldwide in 2025, and deeply analyzes the implications of mechanistic breakthroughs for optimizing diagnosis and treatment strategies, aiming to anchor the direction for innovative breakthroughs and clinical translation in basic lung transplantation research.

ObjectiveTo investigate the contamination status and drug resistance of diarrheagenic Escherichia coli (DEC) in commercially available frozen poultry and livestock meat and their products in Zhangzhou City, and to provide a reference basis for the prevention and control of foodborne diseases caused by DEC. MethodsIn 2024, a total of 240 samples of frozen poultry and livestock meat and their products were collected from supermarkets, farmers’ markets, and online stores. Isolation, identification, and drug resistance analyses of DEC were conducted. ResultsAmong the 240 samples, 42 samples tested positive for DEC, with a detection rate of 17.50%. Specifically, the DEC detection rate in frozen poultry meat and its products （21.15%） was significantly higher than that in frozen livestock meat and its products （10.71%） (χ²=4.122, P=0.042); the detection rate in the first and fourth quarters （26.67%） was higher than that in the second and third quarters （8.33%） (χ²=13.968, P=0.003). A total of 44 DEC strains were isolated, among which enteroaggregative Escherichia coli (EAEC) was the dominant pathotype, accounting for 90.91%, and mainly carried the astA gene, followed by the pic gene. At a distance level of 10 000 in matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS) cluster analysis, the 44 DEC strains were divided into 2 major clusters, with 29 strains in Cluster Ⅰ and 15 strains in Cluster Ⅱ； at a distance level of 200, the strains could be classified into 12 types, with type c being the dominant one (27.27%). Among the 44 DEC strains, 37 DEC strains showed different degrees of resistance to 11 categories of antibiotics, 36 strains were resistant to 3 or more classes of antibiotics, with multidrug-resistant strains accounting for 81.82%, and 21 strains were resistant to more than 7 types of antibiotics. ConclusionThe detection rate of DEC in commercially available frozen poultry and livestock meat and their products in Zhangzhou City is relatively high, and the prevalence of multidrug resistance is severe. These findings should warrant the attention of relevant authorities, to strengthen food safety supervision and the management of antibiotic use, and enhance public health education to reduce the risk of foodborne diseases caused by DEC contamination.

Background: The global rise in visual impairment, driven by population aging, the increasing prevalence of lifestyle-related chronic diseases, and environmental factors, has made it a critical public health concern, highlighting the urgent need for effective preventive strategies and eye health maintenance. Cuscutae Semen (CS), a traditional Chinese herbal medicine long regarded for its vision-enhancing properties, has been widely used to support ocular health. However, its underlying molecular mechanisms and bioactive constituents remain poorly understood, limiting its modernization and broader clinical application. Objective: This study aims to investigate the restorative effects of CS on visual impairment, elucidate its underlying mechanisms, and identify potential active components. Methods: A zebrafish model of visual impairment was established using mepanipyrim to simulate retinal structural damage and visual dysfunction. The therapeutic effects of CS were systematically evaluated through behavioral analyses and histomorphological observations. To elucidate the underlying mechanisms, an integrated approach was employed, combining transcriptome sequencing (RNA-seq), reverse transcription quantitative polymerase chain reaction validation, and immunofluorescence staining to identify critical genes and pathways involved. Furthermore, macroporous resin column chromatography was employed for the fractionation and screening of potential active components. Results: CS treatment significantly alleviated mepanipyrim-induced ocular abnormalities in zebrafish, restoring approximately 82% of the observed morphological defects. Behavioral assessments revealed that CS-treated zebrafish exhibited markedly increased swimming speed and distance, indicating enhanced visual light sensitivity. Histopathological analysis demonstrated that CS effectively repaired the structure of retinal cell layers. RNA-seq revealed that CS broadly reversed mepanipyrim-induced gene expression disturbances, suggesting a restorative effect on transcriptomic homeostasis. Gene Ontology enrichment analysis identified the phototransduction pathway as a key mediator of CS’s therapeutic effects. This was further supported by reverse transcription quantitative polymerase chain reaction validation of critical genes and immunofluorescence staining, which confirmed the restored expression of Pde6a and Gnat2, key proteins involved in photic signal transmission. Active component screening indicated that high-polar constituents, including chlorogenic acid, may constitute one of the major bioactive fractions responsible for the observed therapeutic effects. Conclusion: This study provides evidence of the vision-protective effects of CS in a zebrafish model, demonstrating that its therapeutic mechanism involves modulation of the phototransduction pathway. Chlorogenic acid was identified as one of the key bioactive constituents contributing to this effect. These findings not only provide scientific validation for the traditional use of CS in ocular protection but also present promising therapeutic prospects for the prevention and treatment of visual impairment.

Objective To investigate the immediate effect of transcranial direct current stimulation(tDCS)combined with seated Tai-jiquan Yunshou training under different sequences on cerebral cortical activation in stroke patients with hemiple-gia.Methods From September to December,2024,14 stroke inpatients with hemiplegia were enrolled from the Fifth Hospi-tal of Xiamen.Based on the routine medication and rehabilitation,the patients were randomly assigned to a spe-cific intervention sequence,receiving three interventions in a fixed order:tDCS followed by Yunshou(S-Y group),Yunshou followed by tDCS(Y-S group),and simultaneous tDCS and Yunshou(Sim group).Functional near-infrared spectroscopy was used to detect oxyhemoglobin(HbO?)concentration in bilateral sensorimotor cor-tex,premotor and supplementary motor cortex,and prefrontal cortex before and after each intervention.Results Three patients dropped out.In all the regions of interest,inter-group effects were significant in HbO? concentra-tions(F>3.697,P<0.05),and interaction effects were significant in some brain regions(F>3.276,P<0.05).Post-hoc test showed a general trend of Sim Group≥S-Y Group>Y-S Group(P<0.05),although some varia-tions existed across different brain regions.Conclusion Both simultaneous intervention(tDCS and Yunshou)and tDCS followed by Yunshou are more effective on immediate activation of key motor-related cortices in stroke patients with hemiplegia than Yunshou followed by tDCS intervention.

ObjectiveTo investigate the characteristics and distribution of traditional Chinese medicine （TCM） syndromes in the patients with esophageal squamous cell carcinoma （ESCC）. MethodsAn electronic questionnaire was developed to collect the general data and four examination information of ESCC patients treated in 10 areas with high incidence of esophageal cancer in China from June 2020 to March 2021. Multiple analyses including frequency analysis， factor analysis， and hierarchical cluster analysis were performed to analyze the potential syndrome elements， disease location， and common syndromes of ESCC. ResultsA total of 2 027 patients with ESCC were included. Statistical analysis was performed on 113 symptoms， physical signs， 33 tongue manifestation variables， and 23 pulse manifestation variables of the patients’ four examination information. Factor analysis was performed on 55 variables with frequency>10%， extracting 19 common factors. According to clinical experience and expert opinions， the main lesions of patients with ESCC were in the spleen and stomach， and the main syndrome elements were Qi stagnation， blood stasis， phlegm， dampness， and Qi deficiency， with the syndrome element combination of phlegm obstruction + Qi stagnation + blood stasis being the most common. The syndromes can be classified into four categories of liver-stomach disharmony + combined phlegm and Qi obstruction， kidney-spleen dysfunction + combined phlegm and stasis， spleen-kidney Yang deficiency + obstinate phlegm and blood stasis， and liver-kidney Yin deficiency + obstinate phlegm and blood stasis. The main syndrome of ESCC was liver-stomach disharmony + combined phlegm and Qi obstruction in the early stage， liver-spleen dysfunction + combined phlegm and stasis in the middle stage， and spleen-kidney Yang deficiency + obstinate phlegm and blood stasis in the late stage. ConclusionESCC mainly has main pathological features of internal deficiency and external excess and combined deficiency and excess， with the key syndrome elements being phlegm obstruction， Qi stagnation， and blood stasis. The main disease locations are in the spleen and stomach， involving the liver， kidney， chest and diaphragm， heart， and lung. The main syndrome is liver-stomach disharmony + combined phlegm and Qi obstruction.
