Current studies on electroencephalogram (EEG) emotion recognition primarily concentrate on discrete stimulus paradigms under controlled laboratory settings, which cannot adequately represent the dynamic transition characteristics of emotional states during multi-context interactions. To address this issue, this paper proposes a novel method for emotion transition recognition that leverages a cross-modal feature fusion and global perception network (CFGPN). Firstly, an experimental paradigm encompassing six types of emotion transition scenarios was designed, and EEG and eye movement data were simultaneously collected from 20 participants, each annotated with dynamic continuous emotion labels. Subsequently, deep canonical correlation analysis integrated with a cross-modal attention mechanism was employed to fuse features from EEG and eye movement signals, resulting in multimodal feature vectors enriched with highly discriminative emotional information. These vectors are then input into a parallel hybrid architecture that combines convolutional neural networks (CNNs) and Transformers. The CNN is employed to capture local time-series features, whereas the Transformer leverages its robust global perception capabilities to effectively model long-range temporal dependencies, enabling accurate dynamic emotion transition recognition. The results demonstrate that the proposed method achieves the lowest mean square error in both valence and arousal recognition tasks on the dynamic emotion transition dataset and a classic multimodal emotion dataset. It exhibits superior recognition accuracy and stability when compared with five existing unimodal and six multimodal deep learning models. The approach enhances both adaptability and robustness in recognizing emotional state transitions in real-world scenarios, showing promising potential for applications in the field of biomedical engineering.

OBJECTIVE To quantitatively evaluate the effect on decolonization of gram-negative bacteria(GNB)and carbapenem-resistant gram-negative bacteria(CRGNB)in water sinks of neonatal wards and compare the decoloni-zation effects among the 500 mg/L,1000 mg/L of chlorine-containing disinfectants and 3％hydrogen peroxide so-lution.METHODS A total of 15 water sinks were chosen from West China Second University Hospital of Sichuan University as the research subjects,which were randomly divided into the 500 mg/L chlorine-containing disinfect-ant group,the 1000 mg/L chlorine-containing disinfectant group and the 3％hydrogen peroxide solution group.The bacterial colony counts of GNB and CRGNB as well as microbial diversity at the drain outlets were ob-served and compared before the intervention and after the disinfectants were continuously poured for 7 days.RESULTS There were GNB and CRGNB colonized at the drain outlets of water sinks in the neonatal wards under the mode of regular rinsing with 500 mg/L of chlorine-containing disinfectant,with Pseudomonadaceae dominant.There were no significant differences in the bacterial colony counts of GNB/CRGNB,Alpha diversity(Shannon index)and Beta diversity(Bray-Curtis distance)among the three types of disinfectants after the inter-vention for 7 days.CONCLUSIONS There are still large quantity of GNB and CRGNB colonized at the drain outlets of water sinks of neonatal wards after daily conventional treatment with 500 mg/L of chlorine-containing disinfect-ant.Neither the disinfectant with the concentration of chlorine increasing to 1000 mg/L nor 3％hydrogen peroxide solution can remarkably reduce the colonization or alter the microbial diversity.The optimal disinfection strategy should be formulated based on compound disinfectant,physical intervention and project reconstruction.

Objective To analyze the disease burden of hip osteoarthritis(HOA)and its changing trends in China from 1990 to 2021.Methods Utilizing the Global Burden of Disease(GBD)2021 database,age-standardized incidence rate(ASIR),age-standardized prevalence rate(ASPR),and age-standardized disability adjusted life years(DALY)rate(ASDR)of HOA were compared and analyzed in China,globally,and in regions with high sociodemographic index(SDI)from 1990 to 2021.Joinpoint regression model was used to analyze the temporal trend of disease burden,and age and gender were combined to deeply analyze the disease burden of HOA in China.Meanwhile,the age-period-cohort model was used to analyze the influencing factors and the Bayesian age-period-cohort model to predict the trend of China's HOA disease burden in the next 10 years.Results The ASIR,ASPR,and ASDR of HOA in China showed an increasing trend from 1990 to 2021[average annual percentage change(AAPC)were 0.87％,0.82％,and 0.81％,respectively,P＜0.001],and their AAPCs were higher than those of the global and high SDI regions,but in 2021,the ASIR,ASPR,and ASDR of China were lower than those of the global and high SDI regions.Crude incidence,crude prevalence,and crude DALY rate in Chinese HOA increased with age,with the highest number of incidence in the 55-59 age group and the highest number of prevalence,DALY,in the 65-69 age group.In 2021,the ASIR,ASPR and ASDR of HOA in Chinese males were 1.25,1.24 and 1.25 times higher than those in females.Changes in the incidence of HOA in China from 1990 to 2021 were influenced by age,period,and birth cohort.Compared with 2021,new cases of HOA are expected to increase by 37.78％by 2035,and the number of incidence cases in people aged 60 years and above will increase significantly.Conclusion The disease burden of HOA in China continued to rise from 1990 to 2021,and prevention and control need to be strengthened,with a focus on men,high BMI,and middle-aged and older populations.

Objective To understand the distribution characteristics of fungi on object surface in hospital environ-ment,and provide reference for the scientific and precise formulation of environment control strategies based on fun-gal in clinic.Methods From December 7 to 23,2023,a total of 60 environmental specimens of 19 categories in 6 departments of a large tertiary first-class hospital were collected and divided into water-related environmental speci-men group,complete facade environmental specimen group,and sanitary ware environmental specimen group.18S rRNA sequencing was performed on specimens with fungi detected.Results Fungal detection rate of environmental specimens was 20.00％(12/60).Sink in the department of endocrinology had the highest fungal colony count(15 CFU/cm2),followed by the air outlet of air disinfection device in the department of thoracic surgery and the in-ternal part of a faucet in the department of endocrinology(both 10 CFU/cm2).The water-related environmental specimen group detected most diverse fungal genera(14 species),with high relative abundances of Aspergillus(100％),Meyerozyma(99.06％),Ophiocordyceps genus(95.63％),and Kodamaea(87.86％).The air outlet of air disinfection device was detected with a high abundance of Chaetomium(44.08％)and Corollospora(39.71％).There was no statistically significant difference in the α-diversity(Shannon and Simpson indices,P values of 0.661 and 0.568,respectively)and β-diversity(P=0.712)among the three environmental specimens.Conclusion Under the routine implementation of basic environmental cleaning and disinfection in medical institutions,fungi are in a low prevalence in the environment.However,moist surfaces and air disinfection device are prone to fungal colonization,and it is necessary to strengthen daily monitoring and take corresponding intervention measures to reduce the risk of infection.

Purpose Hydrogen proton magnetic resonance imaging was used to study the brain metabolism of menstrual-related migraine(MRM)in different states,and to investigate its correlation with clinical features and estrogen and progesterone.Materials and Methods We recruited 36 patients with MRM diagnosed by neurology outpatient experts of the First Affiliated Hospital of Henan University of Science and Technology from April 2019 to August 2022,and also recruited 29 normal women with age-and education-matched.Proton magnetic resonance spectroscopy was used to assess neurochemical brain changes during interictal period(late follicular phase)and ictal period(perimenstrual phase)in them.The point resolved spectroscopic sequence was used to focus on the bilateral medial prefrontal cortex(mPFC)and bilateral thalamus.Sex hormone levels were collected on the same day of MRI acquisition.The ratios of NAA/Cr,GABA/Cr,Glx/Cr and Cho/Cr were observed.Metabolite changes and hormone levels were investigated among two groups.Furthermore,metabolite changes were investigated in a longitudinal design during the interictal period and ictal period.Results There were no significant differences in the levels of estrogen and progesterone both in the late follicular and perimenstrual periods.There were no significant differences in decline rate of them in perimenstrual periods between patients and normal people(P>0.05).During interictal period,the ratio of Cho/Cr in the region of left mPFC was lower significantly in the MRM group than that of control group(U=-2.957,P=0.003)and showed a significant negative correlation with attack frequency(r=-0.398,P=0.018).During ictal period,the women with MRM had significantly lower the ratio of GABA/Cr in the left mPFC and higher the ratio of Glx/Cr in the left thalamus compared to those of controls(U=-2.015,P=0.044;t=2.213,P=0.033).We found no significant correlations between these results and magraine characteristics(P>0.05).In addition,we found the ratio of GABA/Cr did not change(P>0.05),the ratio of Glx/Cr and Cho/Cr in right thalamus increased from interictal towards the ictal state for MRM patients(t=-2.181,P=0.038;Z=-2.414,P=0.016).Conclusion The present study suggests the existence of distinct cerebral metabolism states between MRM and control,and there are dynamic changes in cerebral metabolism with headache attacks.However,there is no significant difference in estrogen and progesterone from normal women,and its neural mechanism still needs to be further studied.

Background: SM-like (LSM) genes a family of RNA-binding proteins, are involved in mRNA regulation and can function as oncogenes by altering mRNA stability. However, their roles in B-cell progression and tumorigenesis remain poorly understood. Methods: We analyzed gene expression profiles and overall survival data of 123 patients with mantle cell lymphoma (MCL). The LSM index was developed to assess its potential as a prognostic marker of MCL survival. Results: Five of the eight LSM genes were identified as potential prognostic markers for survival in MCL, with particular emphasis on the LSM.index. The expression levels of these LSM genes demonstrated their potential utility as classifiers of MCL. The LSM.index-high group exhibited both poorer survival rates and lower RNA levels than did the overall transcript profile. Notably, LSM1 and LSM8 were overexpressed in the LSM.index-high group, with LSM1 showing 2.5-fold increase (p < 0.001) and LSM8 depicting 1.8-fold increase (p < 0.01) than those in the LSM.index-low group.Furthermore, elevated LSM gene expression was associated with increased cell division and RNA splicing pathway activity. Conclusions The LSM.index demonstrates potential as a prognostic marker for survival in patients with MCL. Elevated expression of LSM genes, particularly LSM1 and LSM8, may be linked to poor survival outcomes through their involvement in cell division and RNA splicing pathways. These findings suggest that LSM genes may contribute to the aggressive behavior of MCL and represent potential targets for therapeutic interventions.
