Objective To explore the relationship between triglyceride-glucose index(TyG)and acute ischemic stroke with large vessel occlusion(AIS-LVO)of anterior circulation.Methods A retrospective study was conducted on patients with anterior circulation AIS-LVO who underwent emergency endovascular thrombectomy at Neurovascular Center of The First Affiliated Hospital of Naval Medical University from Jan.2018 to Dec.2019.According to modified Rankin scale(mRS)score 90 d after operation,the patients were assigned to favorable outcome group(mRS score 0-2)or unfavorable outcome group(mRS score 3-6),and the TyG was compared.According to the median of TyG,the patients were assigned to low-TyG group(TyG＜8.57)or high-TyG group(TyG ≥8.57),and the clinical data,laboratory indexes,and imaging characteristics were compared.Receiver operating characteristic curve was used to evaluate the predictive value of TyG for poor prognosis.Results A total of 135 patients were enrolled,with 72 in the favorable outcome group and 63 in the unfavorable outcome group.The TyG of the unfavorable outcome group was significantly higher than that of the favorable outcome group(8.82+0.63 vs 8.43+0.60,P＜0.001).There were 67 patients in the low-TyG group and 68 in the high-TyG group.Compared with the low-TyG group,the proportion of patients with hyperlipidemia history(P=0.003),systolic blood pressure at admission(P=0.018),fasting blood glucose level(P＜0.001),and triglyceride level(P＜0.001)were significantly higher in the high-TyG group,the infarct core volume was significantly larger(P=0.025),the high density lipoprotein-cholesterol level was significantly lower(P=0.013),and the mRS score 90 d after operation was significantly higher(3[1,5]vs 1[0,5],P=0.049).The TyG had certain predictive value for poor prognosis in anterior circulation AIS-LVO patients(area under curve value=0.662,95％confidence interval 0.571-0.753).Conclusion TyG is elevated in anterior circulation AIS-LVO patients with poor prognosis,and may be a potential prognostic indicator for anterior circulation AIS-LVO patients.

Objective To investigate the correlation between voice fatigue index(VFI)and the subjective and objective assessment results of voice impairment.Methods Fifty-one patients with voice disorders and 48 normal subjects were selected for VFI assessment and comparison of the differences in scores between the two groups.Sub-jective voice handicap index(VHI)and objective acoustic assessment were performed on the patients with voice dis-orders to analyze the correlation between VFI scores and the results of subjective and objective assessment of voice disorders.Results There was significant difference of the VFI scores between the voice disorder patients and the control group,with the total VFI score,part Ⅰ and part Ⅱ scores higher than those of control group,and the partⅢ score lower than those of the control group(P＜0.05),and there was a strong correlation between the total and part VFI scores and the total and part VHI scores(P＜0.05 or P＜0.01).The VFI part Ⅰ and part Ⅱ scores were regatively correlated with the I-low(P＜0.05),but there was not a significant correlation with the other acoustics parameters and the dysphonia severity index(DSI)(P＞0.05).Conclusion Voice fatigue symptoms were more prominent in the voice-impaired population,and the VFI score was significantly correlated with the subjective voice disorder severity,but the correlation with the objective acoustic parameters was not significant.

Objective To study the syntactic impairment characteristics of wh-question comprehension and expression in Chinese non-fluent aphasic patients.Methods The differences in comprehension and expression be-tween 25 non-fluent aphasic patients and 25 normal subjects were tested in the form of sentence-figure matching and elicitation-repetition to analyze syntactic impairment characteristics related to sentence patterns,question objects,and question words.Results The patients with non-fluent aphasia had impaired comprehension and expression of specific interrogative sentences,and the order of correct comprehension was:(active interrogative sentence,object pseudo-split interrogative sentence)＞(subject pseudo-split interrogative sentence,passive interrogative sentence),and the order of correct expression was:active interrogative sentence＞(pseudo-split interrogative sentence,pas-sive interrogative sentence).Conclusion The pattern of impaired comprehension and expression of wh-question was similar in patients with Chinese non-fluent aphasia.The main influences on syntactic structure included the object of questioning(subject-object)and the type of sentence.Obstacles were more pronounced in sentences with wh-move-ment and non-canonical order.

Objective To explore the association between cardiorespiratory fitness and total atherosclerotic burden of brain-and heart-arteries in patients with ischemic stroke.Methods This study retrospectively enrolled consecutive patients with ischemic stroke of the large-artery atherosclerosis or small-artery occlusion subtypes accompanied by cervicocephalic atherosclerosis,who were admitted to the Department of Neurology,Xuanwu Hospital,Capital Medical University,between May 2023 and December 2024.General and clinical data,including age(＜60years,≥60years),sex,admission blood pressure,body mass index,history of hypertension,diabetes mellitus,hyperlipidemia,ischemic stroke,symptomatic coronary artery disease,smoking,alcohol consumption,and medication use(including antiplatelet drugs,anticoagulants,lipid-lowering drugs,antidiabetic drugs,antihypertensive drugs,and β-blockers),characteristics of ischemic stroke(including the duration of onset,ischemic side[left,right,bilateral],and ischemic location[anterior circulation,posterior circulation,bilateral circulation])were collected from all patients enrolled.On the morning after admission,fasting venous blood samples were collected to measure the levels of triglycerides,total cholesterol,low-density lipoprotein cholesterol,high-density lipoprotein cholesterol,fasting blood glucose,glycated hemoglobin,homocysteine,fibrinogen,D-dimer,C-reactive protein,high-sensitivity C-reactive protein,N-terminal pro-B-type natriuretic peptide,creatine kinase-MB,cardiac troponin T,and myoglobin.Transthoracic echocardiography was performed within 7 days after admission to evaluate cardiac function.Left ventricular ejection fraction and cardiac output were recorded,and cardiac index were calculated.Upon admission,neurological impairment,disability,motor function,and balance ability were assessed using the National Institutes of Health stroke scale(NIHSS),modified Rankin scale(mRS),Fugl-Meyer assessment(FMA),and Berg balance scale,respectively.The Saltin-Grimby physical activity level scale was used to evaluate the intensity of habitual physical activity prior to stroke onset.Cardiopulmonary exercise testing was performed within 7 days after admission to assess cardiopulmonary fitness.During the test,peak oxygen uptake(VO2peak),percentage of predicted VO2peak(VO2peak%pred),and metabolic equivalent of task(MET)were recorded.Based on the minimum oxygen uptake required for independent living(15 ml/[kg·min]),VO2peak was classified into low VO2peak(＜15 ml/[kg·min])and high VO2peak(≥15 ml/[kg·min]).With VO2peak%pred＜0.60 as the cutoff,VO2peak%pred was divided into low VO2peak%pred(＜0.60)and high VO2peak%pred(≥0.60).MET were categorized into low MET(＜mean MET)and high MET(≥mean MET)according to the mean value of MET in this study population.Imaging data of cardio-cerebral arteries were obtained by simultaneous CT arteriography within 7 days after admission.Total atherosclerotic burden of brain-and heart-supplying arteries(TAB-BHAs)was used to quantitatively evaluate the overall degree of cardio-cerebral atherosclerosis.And patients were stratified into high TAB-BHAs(≥4 points)and low TAB-BHAs(＜4 points)groups.The differences in general and clinical characteristics,as well as cardiopulmonary fitness indices,were assessed among different groups of TAB-BHAs.Spearman' s correlation was used in the preliminary analysis of the relationship between cardiorespiratory fitness indicators and TAB-BHAs.Multivariate Logistic regression was conducted with VO2peak,low VO2peak%pred,and low METs as independent variables,and high TAB-BHAs as the dependent variable to assess the association between cardiopulmonary fitness and TAB-BHAs.Covariates were selected through regressions stratified by age≥60 years,male,the least absolute shrinkage and selection operator(LASSO),and the variables exhibit statistically significant differences between the low and high TAB-BHAs groups,respectively.Results A total of 104 patients with ischemic stroke were enrolled.Among all patients enrolled,60patients(with ages ranging from 30 to 72years and a mean age of[54±11]years)met the inclusion and exclusion criteria,and were ultimately included.Amid the 60 patients,52 were male and 8 were female.There were 20 patients(33.3%)with low VO2peak,28 patients(46.7%)with low VO2peak%pred,and 31 patients(51.7%)with low MET(MET＜5.0).45 patients were classified into the low TAB-BHAs group and 15 into the high TAB-BHAs group.(1)Compared with the low TAB-BHAs group,patients in the high TAB-BHAs group were significantly older and had a higher proportion of patients aged≥60 years,they also showed significantly higher fibrinogen levels and a history of antihypertensive drug use(all P＜0.05).No significant differences were observed in other general or clinical characteristics between the two groups(all P＞0.05).Regarding cardiopulmonary fitness parameters,patients in the high TAB-BHAs group had lower VO2peak and MET levels,and higher proportions of patients with low VO2peak,low VO2peak%pred,and low MET compared with those in the low TAB-BHAs group(all P＜0.05).(2)Based on the Spearman's correlation analysis,VO2peak(r=-0.298,P=0.021),VO2peak%pred(r=-0.305,P=0.018),MET(r=-0.303,P=0.018)all exhibited negative correlations between and TAB-BHAs.(3)LASSO regression was used to identify the most pertinent variables for high TAB-BHAs,including low VO2peak,low VO2peak%pred,and fibrinogen.Multivariate Logistic regression analysis was then performed with low VO2peak,low VO2peak%pred,and low MET as independent variables and high TAB-BHAs as the dependent variable.The results showed that after adjusting for age≥60 years,male,and fibrinogen,both low VO2peak(adjusted OR,4.420,95%CI 1.052-18.573,P=0.042)and low VO2peak%pred(adjusted OR,7.423,95%CI 1.411-39.046,P=0.018)were independently associated with high TAB-BHAs in ischemic stroke patients.After further adjusting for variables that differed among high and low TAB-BHAs groups(including age≥60 years,male,fibrinogen,and history of using antihypertensive drugs),multivariate Logistic regression showed that low VO2peak%pred remained independently associated with high TAB-BHAs in ischemic stroke patients(adjusted OR,6.347,95%CI 1.170-34.418,P=0.032).Conclusion Poor cardiopulmonary fitness might be associated with high degree of overall cardio-cerebral atherosclerosis,suggesting cardiorespiratory fitness as a potential correlated indicator that could provide clues for improving early screening of patients with heavy cardio-cerebral atherosclerotic burden and for exploring the underlying mechanisms.

How medical resources can be fairly distributed in a public health emergency such as COVID-19. There have been mature or comparatively mature studies on this issue in both traditional ethics and contemporary ethics: the traditional ethics has the "maximum happiness principle" represented by utilitarianism, while the contemporary ethics has the new principle doctrine and the medical justice theory, which respectively put forward the methods suitable for the distribution of emergency medical resources, and defended their respective theories from different perspectives. However, when COVID-19 broke out, the actual medical resource distribution methods were still the traditional medical resource distribution methods, but did not use the contemporary mainstream ethical medical distribution approach, which was due to the limitations of the emerging medical ethics distribution theory. Therefore, in order to better provide ethical services to the medical and health field, the contemporary emerging theory of distribution of health care needs to introduce global bioethics, with its tolerance and respect, give full play to its advantages, and improve its shortcomings, so as to solve the problem of medical resources distribution.

Objective To analyze the quality of life and its influencing factors among patients with occupational coal workers' pneumoconiosis (hereinafter referred to as "coal workers' pneumoconiosis"). Methods A total of 404 coal workers' pneumoconiosis patients diagnosed in Fengjie County of Chongqing City were selected as the study subjects using the convenient sampling method, and their quality of life was investigated by the SF-36 scale. Results The total score of quality of life of the subjects was (63.1±12.1) points. Their scores in the eight dimensions of physical functioning, role-physical, bodily pain, general health subscales, vitality, social functioning, role-emotional, and mental health subscales were lower than that of norms for Chongqing City and the nation (all P<0.05). The results of multiple linear regression analysis showed that the total score of quality of life of the patients decreased with the increase of age and stage of pneumoconiosis (all P<0.01). The total score of quality of life of patients living in urban areas was higher than that of rural patients(P<0.01). The total score of quality of life of patients who had left their jobs was higher than that of retired patients (P<0.01). The total score of quality of life of smoking patients and those with complications was lower than that of non-smokers and those without complications (all P<0.01). Conclusion Age, place of residence, smoking, stage of pneumoconiosis, work status, and complications of pneumoconiosis were the main influencing factors of quality of life among coal workers' pneumoconiosis patients.
