Differentiating ictal/subclinical spikes and waves in childhood absence epilepsy by spectral and network analyses: A pilot study

ObjectiveChildhood absence epilepsy (CAE) is a disease with distinct seizure semiology and electroencephalographic (EEG) features. Differentiating ictal and subclinical generalized spikes and waves discharges (GSWDs) in the EEG is challenging, since they appear to be identical upon visual inspection. Here, spectral and functional connectivity (FC) analyses were applied to routine EEG data of CAE patients, to differentiate ictal and subclinical GSWDs.MethodsTwelve CAE patients with both ictal and subclinical GSWDs were retrospectively selected for this study. The selected EEG epochs were subjected to frequency analysis in the range of 1–30 Hz. Further, FC analysis based on the imaginary part of coherency was used to determine sensor level networks.ResultsDelta, alpha and beta band frequencies during ictal GSWDs showed significantly higher power compared to subclinical GSWDs. FC showed significant network differences for all frequency bands, demonstrating weaker connectivity between channels during ictal GSWDs.ConclusionUsing spectral and FC analyses significant differences between ictal and subclinical GSWDs in CAE patients were detected, suggesting that these features could be used for machine learning classification purposes to improve EEG monitoring.SignificanceIdentifying differences between ictal and subclinical GSWDs using routine EEG, may improve understanding of this syndrome and the management of patients with CAE.     

聚焦解决护理模式结合健康教育对银屑病患者心理状态、应对方式的影响

目的 探讨聚焦解决护理模式结合健康教育对银屑病患者心理状态、应对方式的影响。方法 选取2020年2月至2021年2月我院收治的100例银屑病患者,随机分为观察组(聚焦解决护理模式结合健康教育)与对照组(常规健康教育)。比较两组的心理状态及应对方式。结果 干预后,观察组的焦虑自评量表(SAS)、抑郁自评量表(SDS)评分低于对照组(P<0.05)。干预后,观察组的面对评分高于对照组,屈服、回避评分低于对照组(P<0.05)。干预后,观察组的病耻感评分低于对照组(P<0.05)。结论 聚焦解决护理模式结合健康教育可有效改善银屑病患者的不良情绪,减轻病耻感,转变疾病应对方式。     

Vulnerability of multiple large‐scale brain networks in dementia with Lewy bodies

Aberrations of large‐scale brain networks are found in the majority of neurodegenerative disorders. The brain connectivity alterations underlying dementia with Lewy bodies (DLB) remain, however, still elusive, with contrasting results possibly due to the pathological and clinical heterogeneity characterizing this disorder. Here, we provide a molecular assessment of brain network alterations, based on cerebral metabolic measurements as proxies of synaptic activity and density, in a large cohort of DLB patients (N = 72). We applied a seed‐based interregional correlation analysis approach (p < .01, false discovery rate corrected) to evaluate large‐scale resting‐state networks' integrity and their interactions. We found both local and long‐distance metabolic connectivity alterations, affecting the posterior cortical networks, that is, primary visual and the posterior default mode network, as well as the limbic and attention networks, suggesting a widespread derangement of the brain connectome. Notably, patients with the lowest visual and attention cognitive scores showed the most severe connectivity derangement in regions of the primary visual network. In addition, network‐level alterations were differentially associated with the core clinical manifestations, namely, hallucinations with more severe metabolic dysfunction of the attention and visual networks, and rapid eye movement sleep behavior disorder with alterations of connectivity of attention and subcortical networks. These multiple network‐level vulnerabilities may modulate the core clinical and cognitive features of DLB and suggest that DLB should be considered as a complex multinetwork disorder.     

Sliding mode control of time‐varying delay Markov jump with quantized output

This paper investigates the quantized sliding mode control of Markov jump systems with time‐varying delay. A dynamical adjustment law is explored to quantize the system output. By constructing an observer‐based integral sliding surface, a sliding mode controller is designed to take over the dynamical motion of state estimation and ensure the reachability of sliding surface. A new scaling manner is developed to build the bound between the system output and quantized error. With the help of separation strategies for controller synthesis and general transition probabilities and a lower bound theorem for nonlinear integral terms, a new synthesis method to ensure the required stability and meet the required performance is proposed in the form of linear matrix inequalities. The validity of the proposed control method is illustrated by a numerical example.     

辨体-辨病-辨证诊疗模式在慢性病防治中的应用策略

依据中国防治慢性病中长期规划（2017-2025年），按照国医大师王琦教授倡导的"辨体-辨病-辨证诊疗模式"，提出慢性病"3+4+3"防治路向：面向三类人群（一般、高危、患病人群），朝向四种状态（无病、病前、病中、病后状态），指向三辨模式（辨体-辨病-辨证诊疗模式）。进而探讨其应用策略：对于一般人群无病状态——辨体养生，固本防病；对于高危人群病前状态——辨体干预，治本救萌；针对患病人群病中状态——"三辨"施治，标本兼顾；针对患病人群病后状态——辨体调理，固本防复。文中结合案例加以佐证，具有临床指导价值。     

“混合式教学+医学教育”实现教学评价研究

教学评价是教学过程中不可或缺的,行之有效的教学评价是促进教学方法改革,增强教学效果的指挥棒。与传统的教学方法相比较在混合式医学教学课堂中,教学评价也应进行相应的改革,从教师、自身、同行三个维度研究混合式医学教学中的教学评价方法的改革。同时强调完善教学评价的反馈机制。通过学生反馈、专家反馈、同行反馈、自身反馈,建立完整的混合式教学+医学教育的教学评价体系。
