Neuromyelitis optica spectrum disorders (NMOSDs) are most common in anti-aquaporin 4 (AQP4) antibody positive NMOSDs, which are characterized by recurrent episodes of optic neuritis and myelitis, etc., and severely reduce the quality of life. In recent years, new insights into the diagnostic techniques, diagonstic markers, and immunotherapy of anti - AQP4 antibody positive NMOSDs have continued to emerge, and here we focus on synthesizing new advances in the diagnostic techniques and diagonstic markers of anti-AQP4 antibody positive NMOSDs and the most recent recommendations for its treatment, in hopes of summarizing to promote the understanding and application of new diagnostic and therapeutic techniques for anti-AQP4 antibody positive NMOSDs in China, and to explore more possible clinical diagnostic and therapeutic approaches.

Objective To preliminarily summarize the epidemiological and clinical characteristics of functional movement disorder (FMD) based on movement disorders clinic in China. Methods and Results A total of 593 patients with movement disorders newly diagnosed in movement disorders clinic of 22 clinical medical centers from August to September in 2023 were included, including 37 patients (6.24%) with FMD and 556 patients (93.76%) with organic movement disorder. Comparison of the epidemiological characteristics of the 2 groups, the proportions of corona virus disease (COVID⁃19) infection (χ2 = 4.217, P = 0.040) and psychopsychological symptoms (χ2 = 18.694, P = 0.000) in the FMD group were higher than those in the organic movement disorder group, while age (t = 3.757, P = 0.000), age of onset (t = 3.720, P = 0.000) and proportion of hypertension (χ2 = 4.736, P = 0.030) were lower than those in the organic movement disorder group. Comparison of the clinical characteristics of the 2 groups, the FMD group had higher proportions of tremor (χ2 = 3.955, P = 0.047) and myoclonus (Fisher′s exact probability: P = 0.011) than the organic movement disorder group, and the proportions of parkinsonism (χ2 = 8.491, P = 0.004) and gait disorder (χ2 = 5.028, P = 0.025) were lower than those in the organic movement disorder group. Conclusions The age and age of onset, as well as the proportions of COVID⁃19 infection, hypertension, psychopsychological symptoms, tremor, myoclonus, parkinsonism and gait disorder with FMD were different from those with organic movement disorder in China.

To examine physical activity (PA) of post-percutaneous coronary intervention (PCI) patients and explore the demographic, clinical, and social psychological characteristics associated with PA levels.

Improving the digital citizenship of secondary vocational students is critical for cultivating vocational talents in education. It is an inevitable requirement for modernizing vocational education. Focusing on social media competence, this study explores possible ways to improve the digital citizenship of secondary vocational students. A total of 469 secondary vocational students in Wuhan city, Hubei province, were investigated using questionnaires. The data analysis shows that the four dimensions of social media competence (technical use, content interpretation, content generation, and anticipatory reflection) significantly predict digital citizenship. On this basis, we propose four paths for improving the digital citizenship of secondary vocational students: creating a suitable environment for secondary vocational students to apply their skills in information technology; enhancing the ability of secondary vocational students to discriminate about information on the Internet; improving students' interpersonal communication ability when dealing with technical support; building an early warning system for secondary vocational students' behavioral perception.

Dyslipidemia is the most prevalent independent risk factor for patients with chronic kidney disease (CKD). Lipid-induced NLRP3 inflammasome activation in kidney-resident cells exacerbates renal injury by causing sterile inflammation. Nuclear factor erythroid 2-related factor 2 (Nrf2) is a transcription factor that modulates the cellular redox balance; however, the exact role of Nrf2 signaling and its regulation of the NLRP3 inflammasome in hyperlipidemia-induced kidney injury are poorly understood. In this study, we demonstrated that activation of the mtROS–NLRP3 inflammasome pathway is a critical contributor to renal tubular epithelial cell (RTEC) apoptosis under hyperlipidemia. In addition, the Nrf2/ARE signaling pathway is activated in renal tubular epithelial cells under hyperlipidemia conditions both in vivo and in vitro, and Nrf2 silencing accelerated palmitic acid (PA)-induced mtROS production, mitochondrial injury, and NLRP3 inflammasome activation. However, the activation of Nrf2 with tBHQ ameliorated mtROS production, mitochondrial injury, NLRP3 inflammasome activation, and cell apoptosis in PA-induced HK-2 cells and in the kidneys of HFD-induced obese rats. Furthermore, mechanistic studies showed that the potential mechanism of Nrf2-induced NLRP3 inflammasome inhibition involved reducing mtROS generation. Taken together, our results demonstrate that the Nrf2/ARE signaling pathway attenuates hyperlipidemia-induced renal injury through its antioxidative and anti-inflammatory effects through the downregulation of mtROS-mediated NLRP3 inflammasome activation.

Functional gait disorder (FGD) is a common subtype of functional movement disorder (FMD), mainly characterized by instability, lameness and Parkinson's gait. The clinical manifestations of FGD are the same as those of other types of gait disorder, with the possibility of misdiagnosis. However, there are significant differences in the treatment principles between them, so clear diagnosis and accurate treatment are crucial to improve patients' symptoms and prognosis. This paper aims to systematically review the epidemiological characteristics, clinical manifestations, auxiliary examination, diagnosis and differential diagnosis, treatment and prognosis of FGD, in order to improve the understanding of clinicians.
