Background Fatigue driving is an important cause of road traffic accidents in modern society, and the fatigue condition of heavy-duty commercial truck drivers has attracted widespread attention. Research on the fatigue status and influencing factors of heavy-duty commercial truck drivers in China is relatively rare at present. Objective To analyze the main characteristics of fatigue among heavy-duty commercial truck drivers and the impacts of factors such as working hours, insomnia, and occupational burnout on their fatigue status. Methods Using cluster sampling method, a cross-sectional study was conducted from July to August 2023, enrolling heavy-duty commercial truck drivers in long-distance freight logistics markets (stations) located in three administrative regions of W City, Xinjiang Uygur Autonomous Region. A self-designed questionnaire was used to collect demographic and occupational characteristics of heavy-duty commercial truck drivers, and the Chinese versions of Fatigue Scale-14 (FS-14), Athens Insomnia Scale (AIS), and Maslach Burnout Inventory General Survey (MBI-GS) were used to evaluate their fatigue, insomnia, and occupational burnout status, respectively. Mann-Whitney U test and Kruskal-Walls H test were used to compare intergroup differences, and Spearman correlation coefficient was used to analyze the correlation between variables. Hierarchical regression models were used to study the impacts of selected variables on fatigue status. Results This study obtained 311 valid questionnaires, with a valid recovery rate of 88.86% (311/350). The physical fatigue, mental fatigue, and total fatigue scores of the survey subjects in M (P₂₅, P₇₅) were 3.00 (2.00, 4.00), 2.00 (1.00, 3.00), and 5.00 (4.00, 6.00), respectively. The comparison results showed that, except for smoking, there were statistically significant differences in total fatigue scores between different groups of age, marital status, number of children, educational level, service length of freight transportation, average daily working time, and average monthly income (P<0.05). The difference in total fatigue score among the groups without sleep disorders, with suspected insomnia, and with insomnia was statistically significant (P<0.001). The difference in total fatigue score among the groups without occupational burnout, with moderate occupational burnout, and with severe occupational burnout was also statistically significant (P<0.001). Positive correlations were found between insomnia score and scores of physical fatigue (r_s=0.507), mental fatigue (r_s=0.547), and total fatigue (r_s=0.618) (P<0.001). Hierarchical regression models revealed that having more children, extended daily working hours, insomnia, and increased scores of decreased personal accomplishment were negative factors affecting the fatigue status of heavy-duty commercial truck drivers (P<0.05), and the final regression equation was: total fatigue score=7.579+0.581×number of children+0.916×average daily working time+0.434×score of AIS+0.754×score of reduced personal accomplishment. Conclusion The fatigue status of heavy-duty commercial truck drivers is not optimistic. An increase in the number of children, extended daily working hours, severe insomnia symptoms, and increased scores of decreased personal accomplishment associate with their worse fatigue status.

Objective To study the protective effect and possible mechanism of dexmedetomidine on sevoflurane-induced cognitive impairment.Methods 40 rats were randomly divided into a blank group,model group,dexmedetomidine group,and combination group,10 for each group.A rat model of sevoflurane-induced cognitive impairment was established in the model group,dexmedetomidine group,and combination group.The dexmedetomidine group and combination group were intraperitoneally injected with dexmedetomidine of 50 μg/kg 30 min before modeling,so was the combination group injected with sulindac of 5 mg/kg.The blank group and model group were intravenously injected with equal amount of saline.Morris water maze test was used to detect cognitive function.Enzyme-linked immunosorbent assay(ELISA)was used to detect serum levels of homocysteine(Hcy)and monocyte chemoattractant protein-1(MCP-1);high-performance liquid chromatography was used to detect hippocampal glutamate(Glu)and γ-aminobutyric acid(GABA)contents.Immunoblotting was used to detect hippocampal glycogen synthase kinase 3β(GSK-3β)and β-catenin protein expression levels.Results The escape latency in the dexmedetomidine group rats was shorter than that in the model group(P<0.05),the number of crossing the original platform was greater than that in the model group(P<0.05),and duration staying in the original platform quadrant was longer than that in the model group(P<0.05).The escape latency in the combination group was longer than that in the dexmedetomidine group(P<0.05),the number of crossing the original platform was smaller than that in the dexmedetomidine group(P<0.05),and duration staying in the original platform quad-rant was shorter than that in the dexmedetomidine group(P<0.05).Serum levels of Hcy and MCP-1 were higher in the model group than in the blank group(P<0.05),lower in the dexmedetomidine group than in the model group(P<0.05),and higher in the combination group than in the dexmedetomidine group(P<0.05).Hippocam-pal Glu content was higher in the model group than in the blank group(P<0.05),while GABA content was lower(P<0.05).Hippocampal Glu content was lower in the dexmedetomidine group than in the model group(P<0.05),whereas GABA content was higher group(P<0.05).Hippocampal Glu content was higher in the combination group than in the dexmedetomidine group(P<0.05),and GABA content was lower(P<0.05).Hippocampal GSK-3β protein expression level was higher in the model group than in the blank group(P<0.05),but the β-catenin protein expression level was lower(P<0.05).Hippocampal GSK-3β protein expression level was lower in the dexmedetomidine group than in the model group(P<0.05),while β-catenin protein expression level was higher(P<0.05).Hippocampal GSK-3β protein expression level was higher in the combination group than in the dexme-detomidine group(P<0.05),whereas β-catenin protein expression level was lower(P<0.05).Conclusions Dexmedetomidine may improve cognitive function in rats with sevoflurane-induced cognitive impairment by activat-ing the Wnt/β-catenin signaling pathway,reducing inflammation,and enhancing neurotransmitter activity.

Objective To explore the risk factors of prognosis of patients with intracerebral hemorrhage at 6 months after operation,and to study the diagnostic efficacy of event-related potential(ERP)on outcome and prognosis.Methods Forty postoperative patients with intracerebral hemorrhage were prospectively enrolled.The age,sex,preoperative blood loss and GCS were collected.The mismatch negative wave(MMN)was measured by ERP on the 1st,3rd,7th and 14th day after operation,and the modified coma recovery scale(CRS-R)was evaluated simultaneously.The Glasgow outcome scale(GOS)of patients was assessed by telephone follow-up after 6 months GOS 1～2 and 3～5 was defined as poor prognosis and good prognosis.,respectively.Multivariate Logistic regression analysis was used to analyze the risk factors affecting the outcome and prognosis of patients,to explore the correlation between MMN and CRS-R,and ROC curve was used to evaluate the predictive value of MMN on the prognosis of patients.Results There were significant differences in the preoperative blood loss,admission GCS score and MMN amplitude between patients with good prognosis and those with poor prognosis on the 3rd,7th and 14th day after operation.Multivariate Logistic regression analysis showed that MMN amplitude on the 14th day after operation was an independent risk factor for poor prognosis(OR=0.100,95%CI:0.000～0.355,P<0.05).The amplitude of MMN was strongly correlated with CRS-R and the correlation coefficient was 0.643(P<0.01).The amplitude of MMN on the 14th day after operation had a high diagnostic efficiency for the clinical prognosis at 6 months.Conclusion The lower the amplitude of MMN on the 14th day after operation,the worse the prognosis of patients.ERP monitoring of postoperative disturbance of consciousness in patients with intracerebral hemorrhage is expected to become an effective tool to predict the prognosis of patients.

The management of surplus drugs is an important part of drug administration. At present, China′s medical institutions are in the initial exploration stage in managing surplus drugs.This study analyzed the causes, safety hazards, management policies, and management problems of surplus drugs in medical institutions, and proposed targeted countermeasures and suggestions, including establishing unified and standardized management methods, consensus or guidelines, optimizing internal management of medical institutions, improving the management awareness of medical staff, and clarifying the benefits of surplus drugs, so as to provide references for medical institutions to manage surplus drugs reasonably.

To standardize the management of surplus drugs, improve the efficiency of medical resource utilization, promote the rational use of medical insurance funds, and reduce the financial burden on patients, a large tertiary hospital implemented a practice for managing surplus drugs starting in May 2023. This practice encompassed multiple aspects, including the establishment of organizational structure, clarification of responsibilities, formulation of billing for fractional doses and a reasonable surplus drugs list, establishment of standardized management processes, and allocation of special funds for surplus drugs. These efforts had initially achieved effective management of surplus drugs. As of November 2023, the management of surplus drugs had benefited 136 908 patients, with an average savings of 873.61 yuan per patient and a cumulative savings of approximately 34.7 million yuan in medical insurance funds. This practice had effectively reduced the wastage of medical resources, and could provide references for promoting standardized management of surplus drugs in medical institutions of China. In the future, the hospital should further expand the coverage of surplus drugs, ensure patients′ rights to informed consent, and establish a comprehensive performance incentive mechanism to promote the sustainable development of surplus drug management.
