Objective To investigate the features of resting-state electroencephalography(EEG)in stroke patients with limited upper limb movement,and assess its potential utility in evaluating upper limb motor function.Methods From March to August,2024,a total of 71 stroke patients with limited upper limb movement were enrolled as stroke group at the Rehabilitation Hospital Affiliated to Fujian University of Traditional Chinese Medicine;while 63 healthy participants matched for age and sex were recruited as control group.They were tested with 19-chan-nel resting-state EEG(rsEEG),calculating of the pairwise derived brain symmetry index(pdBSI)and Delta/Al-pha ratio(DAR).The motor function was assessed with Fugl-Meyer Assessment-Upper Extremities(FMA-UE),the upper limb recovery was evaluated with Brunnstrom Stages and the activities of daily living was assessed with modified Barthel index(MBI)in stroke patients,Results Compared with the control group,the pdBSI of Global lead,Frontal region,Central region and Posterior region across Delta,Alpha and Beta1 frequency bands were significantly higher in the stroke group than in the control group(|Z|>2.289,P<0.05);as well as the pdBSI of Global lead,Central region and Posterior region across The-ta bands(|Z|>3.016,P<0.01),the pdBSI of Global lead,Frontal region,Central region and Posterior region across Beta2 bands(|Z|>3.222,P<0.01),DAR of Global lead,Frontal region,Central region and Posterior re-gion(|Z|>6.565,P<0.001).In the stroke group,the pdBSI of Global lead(r=-0.280,P=0.018)and Central region(r=-0.304,P=0.010)across the Delta band were significantly negatively correlated with FMA-UE,as well as the pdBSI of Global leads(r=-0.289,P=0.014),Central region(r=-0.244,P=0.040)and Posterior region(r=-0.356,P=0.002)across the Beta1 band,and the DAR of Global lead(r=-0.431,P<0.001),Fron-tal region(r=-0.429,P<0.001),Central region(r=-0.491,P<0.001)and Posterior region(r=-0.482,P<0.001).Conclusion Asymmetry in spectral power between hemispheres in the Delta(0.5 to 4 Hz)and Beta(13 to 20 Hz)bands is found in stroke patients,especially in the central region,which correlates with upper limb function limitations.pdBSI Delta,pdBSI Beta1 and DAR are potential neuroelectrophysiological markers for assessing upper limb motor function in stroke patients.

Weight management is an important initiative to improve the serious situation of overweight and obesity in China,and clinical dietitians in tertiary hospitals are a key part of it.Currently,clinical dietitians in China are facing problems such as unclear role definitions and responsibilities,marginalization of work content and imbalance of resource allocation.A clear definition of responsibilities and an efficient service model are necessary for the effective implementation of weight management.On the basis of constructing the post responsibility matching model for clinical dietitians in tertiary hospitals,it explored the weight management service model for clinical dietitians,analyzed optimization pathways for their workflow,and proposed suggestions for the optimization of the post responsibilities and incentive measures,so as to provide theoretical support and practical paths for the improvement of the population's weight management system.

Objective To predict the potential geographic distribution of Oncomelania hupensis in Yunnan Province using random forest (RF) and maximum entropy (MaxEnt) models, so as to provide insights into O. hupensis surveillance and control in Yunnan Province. Methods The O. hupensis snail survey data in Yunnan Province from 2015 to 2016 were collected and converted into O. hupensis snail distribution site data. Data of 22 environmental variables in Yunnan Province were collected, including twelve climate variables (annual potential evapotranspiration, annual mean ground surface temperature, annual precipitation, annual mean air pressure, annual mean relative humidity, annual sunshine duration, annual mean air temperature, annual mean wind speed, ≥ 0 ℃ annual accumulated temperature, ≥ 10 ℃ annual accumulated temperature, aridity and index of moisture), eight geographical variables (normalized difference vegetation index, landform type, land use type, altitude, soil type, soil textureclay content, soil texture-sand content and soil texture-silt content) and two population and economic variables (gross domestic product and population). Variables were screened with Pearson correlation test and variance inflation factor (VIF) test. The RF and MaxEnt models and the ensemble model were created using the biomod2 package of the software R 4.2.1, and the potential distribution of O. hupensis snails after 2016 was predicted in Yunnan Province. The predictive effects of models were evaluated through cross-validation and independent tests, and the area under the receiver operating characteristic curve (AUC), true skill statistics (TSS) and Kappa statistics were used for model evaluation. In addition, the importance of environmental variables was analyzed, the contribution of environmental variables output by the models with AUC values of > 0.950 and TSS values of > 0.850 were selected for normalization processing, and the importance percentage of environmental variables was obtained to analyze the importance of environmental variables. Results Data of 148 O. hupensis snail distribution sites and 15 environmental variables were included in training sets of RF and MaxEnt models, and both RF and MaxEnt models had high predictive performance, with both mean AUC values of > 0.900 and all mean TSS values and Kappa values of > 0.800, and significant differences in the AUC (t = 19.862, P < 0.05), TSS (t = 10.140, P < 0.05) and Kappa values (t = 10.237, P < 0.05) between two models. The AUC, TSS and Kappa values of the ensemble model were 0.996, 0.954 and 0.920, respectively. Independent data verification showed that the AUC, TSS and Kappa values of the RF model and the ensemble model were all 1, which still showed high performance in unknown data modeling, and the MaxEnt model showed poor performance, with TSS and Kappa values of 0 for 24%(24/100) of the modeling results. The modeling results of 79 RF models, 38 MaxEnt models and their ensemble models with AUC values of > 0.950 and TSS values of > 0.850 were included in the evaluation of importance of environmental variables. The importance of annual sunshine duration (SSD) was 32.989%, 37.847% and 46.315% in the RF model, the MaxEnt model and their ensemble model, while the importance of annual mean relative humidity (RHU) was 30.947%, 15.921% and 28.121%, respectively. Important environment variables were concentrated in modeling results of the RF model, dispersed in modeling results of the MaxEnt model, and most concentrated in modeling results of the ensemble model. The potential distribution of O. hupensis snails after 2016 was predicted to be relatively concentrated in Yunnan Province by the RF model and relatively large by the MaxEnt model, and the distribution of O. hupensis snails predicted by the ensemble model was mostly the joint distribution of O. hupensis snails predicted by RF and MaxEnt models. Conclusions Both RF and MaxEnt models are effective to predict the potential distribution of O. hupensis snails in Yunnan Province, which facilitates targeted O. hupensis snail control.

NAD(P)H: quinone oxidoreductase 1 (NQO1) is a flavin protease highly expressed in various cancer cells. NQO1 catalyzes a futile redox cycle in substrates, leading to substantial reactive oxygen species (ROS) production. This ROS generation results in extensive DNA damage and elevated poly (ADP-ribose) polymerase 1 (PARP1)-mediated consumption of nicotinamide adenine dinucleotide (NAD⁺), ultimately causing cell death. Nicotinamide phosphoribosyltransferase (NAMPT), the rate-limiting enzyme in the NAD⁺ salvage synthesis pathway, emerges as a critical target in cancer therapy. The concurrent inhibition of NQO1 and NAMPT triggers hyperactivation of PARP1 and intensive NAD⁺ depletion. In this study, we designed, synthesized, and assessed a novel series of proqodine A derivatives targeting both NQO1 and NAMPT. Among these, compound T8 demonstrated potent antitumor properties. Specifically, T8 selectively inhibited the proliferation of MCF-7 cells and induced apoptosis through mechanisms dependent on both NQO1 and NAMPT. This discovery offers a promising new molecular entity for advancing anticancer research.
