Objective:To investigate the effects of ginkgolide B on neurological function recovery and the Wnt/β-catenin pathway after ischemic stroke in mice.Methods:Fifty-five C57/BL6 mice were selected, of which 10 mice were kept as the sham group and the remaining 45 mice were constructed as the ischemic stroke model. There were 40 mice who finally completed the modeling, and then they were randomly divided into the blank control group (GB0w), short-course administration group (GB1w), long-term administration group (GB2w), and long-term administration+antagonist group (GB2w+PRI-724), with 10 mice in each group. There was no drug intervention after MCAO in GB0w. The mice in GB1w were given ginkgolide B (10 mg/kg) 0.1 ml within 1 week after MCAO; in GB2w were given ginkgolide B (10 mg/kg) 0.1 ml within 2 weeks after MCAO; and in GB2w+PRI-724 were nasally fed ginkgolide B (10 mg/kg) 0.1 ml within 2 weeks after MCAO; and selective antagonist PRI-724 was given 3 h before administration of ginkgolide B on days 8 to 14. Neurological function scores, walking on rotor bar test scores, expression of transforming growth factor-β1 (TGF-β1), fibroblast growth factor 4 (FGF4), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), malondialdehyde (MDA), glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), Wnt, β-catenin, and glycogen synthase kinase-3β (GSK-3β) were compared among the groups.Results:Compared with the sham group, the expressions of MDA, TNF-α, IL-6, FGF4, and GSK-3β in GB0w, GB1w, GB2w, and GB2w+ PRI-724 were increased, and the expressions of GSH-Px, SOD, TGF-β1, β-catenin, and Wnt were decreased (all P < 0.001). Compared with GB0w, the expressions of SOD, GSH-Px, TGF-β1, Wnt, and β-catenin were increased in GB1w, GB2w, and GB2w+PRI-724, and the expressions of MDA, TNF-α, IL-6, FGF4, and GSK-3β were decreased (all P < 0.001). Compared with GB1w, the expressions of GSH-Px, SOD, TGF-β 1, Wnt, and β-catenin were increased in GB2w and GB2w+PRI-724, and the expressions of IL-6, TNF-α, MDA, FGF4, and GSK-3β were decreased (all P < 0.001). Compared with GB2w, the neural function score, walking on the stick test score, and expressions of IL-6, TNF-α, FGF4, MDA, and GSK-3β were increased in GB2w+PRI-724, while the expressions of GSH-Px, TGF-β1, SOD, Wnt, and β-catenin were decreased (all P < 0.001). Conclusions:Ginkgolide B can effectively improve the neurological function of ischemic stroke mice and may be related to the Wnt/β-catenin pathway.

Objective To explore and analyse the factors influencing the acceptability of"Internet medical alliance"among medical staff by UTAUT model,with a view to providing a basis for the sustainable development of"Internet medical alliance".Methods A questionnaire survey was conducted among medical staff participating in the"Internet medical alliance"in municipal hospitals,count-level hospitals,township health centers,village clinics and community health service centers.SPSS 20.0 and Amos 17.0 software were used to statistically describe the acceptance of"Internet medical alliance",and a structural equation model with behavioral intention and satisfaction as dependent variables was constructed.Results In the range of independent variables,the 841 follow-up subjects had the highest individual creativity score at(3.88±0.67),followed by social influence at(3.86±0.66)and the lowest perceived risk score at(3.52±0.78).Of the dependent variables,the behavioural intention score was(3.86±0.68)and the satisfaction score was(7.72±1.88).Conclusion Facilitation,individual creativity,self-efficacy,performance expectations,effort expectations,having heard of"Internet medical alliance"education level and perceived risk were key factors in the behavioral intention and satisfaction of medical staff to participate in"Internet medical alliance".

The National Conference on Medical Emergency Work in 2024 clearly puts forward the need to continu-ously strengthen the construction of emergency medical rescue system and capacity,does a good job in medical treatment of emergencies,and achieves high-quality development of medical emergency work.On the basis of ana-lysing the current situation of medical emergency rescue system construction,taking the construction practice of the first emergency hospital in China in Guangdong Second People's Hospital as an example,it explores the construc-tion of a new model of medical emergency rescue in large public hospitals,including three kinds of capabilities:the ability to transform the combination of level and emergency,the ability to integrate regional medical rescue and coor-dination,and three-dimensional multifunctional emergency rescue capabilities;and two norms:norms for talent training and norms for the management system.Finally,it puts forward suggestions for strengthening the construc-tion of emergency hospitals.

ObjectiveTo investigate the regulatory effects of Ginkgolide B on the biological characteristics of brain T cells and their interactions with glial cells during the recovery phase of ischemic stroke in mice. Methods36 adult C57BL/6 mice were randomly assigned to three groups: sham-operated group (Sham group), control group (PBS group), and Ginkgolide B treatment group (GB group). The Sham group underwent only sham surgeries, whereas the PBS and GB groups were subjected to a middle cerebral artery occlusion (MCAO) model using the filament method, followed by intranasal administration of an equivalent volume of either PBS or Ginkgolide B solution for 14 days post-injury. Neurological function changes were evaluated in all three groups using the rotarod test and a neurological scoring system. On day 15, single-cell sequencing was performed on fresh tissues from the brain injury areas, surrounding cortex, corpus callosum, and striatum of mice in the PBS and GB group to assess the biological characteristics of T cells and their subpopulations, and further explore the interactions and mechanisms among T cells, microglia, and oligodendrocytes. ResultsCompared with the Sham group, both PBS and GB group exhibited significant improvements in neurological scores and reduced pre-fall motor durations (P < 0.001). Compared with the PBS group, the GB group showed a downward trend in neurological scores and an upward trend in pre-fall motor durations on days 5, 10, and 15 post-ischemic brain injury, with a significant increase in pre-fall motor duration on day 15 (P < 0.05). Compared with the PBS group, the GB group exhibited a significant increase in T cell proliferative activity in the brain 15 days post brain injury (P < 0.05). The number of proliferative T cells and the levels of lipid metabolism were significantly elevated (P < 0.05), and there was a significant increase in extracellular matrix remodeling in all T cells (P < 0.05). Additionally, the interactions between T cells and both microglia and oligodendrocytes, as well as among the microglia themselves and between microglia and oligodendrocytes, were significantly enhanced in the GB group. This was primarily evident in the strengthened interactions between CD74 and macrophage migration inhibitory factor (MIF), as well as colony stimulating factor 1 receptor (CSF1R) and colony stimulating factor 1 (CSF1) (P < 0.05). However, the inflammatory levels of T cells showed no significant differences compared with the PBS group. ConclusionA mouse model of ischemic stroke can be successfully established by MCAO operation. Ginkgolide B may promote neurological recovery post-brain injury in mice by modulating the biological characteristics of T cells within the brain and their interactions with glial cells.
