RESUMEN
Objective:To analyze the consistency and correlation between the Chinese Version of Swanson Nolan and Pelham, Version Ⅳ Scale (SNAP-Ⅳ) and the Integrated Visual and Auditory Continuous Performance Test (IVA-CPT) in the assessment of attention deficit hyperactivity disorder (ADHD), thus providing a reliable basis for the diagnosis of ADHD, and reducing the misdiagnosis rate and missed diagnosis rate.Methods:Clinical data of children to be diagnosed as ADHD in the Department of Children′s Rehabilitation, Yuying Children′s Hospital of the Second Affiliated Hospital of Wenzhou Medical University from October 2019 to July 2020 were collected.A total of 282 SNAP-Ⅳ and IVA-CPT profiles were collected, and the Kappa test and Pearson test were used to retrospectively analyzed for their consistency and correlation in the diagnosis of ADHD. Results:SNAP-Ⅳ and IVA-CPT were consistent in the diagnosis of ADHD (Kappa value=0.514, total coincidence rate=65.6%, P<0.000 1). Inattention subset scores of SNAP-Ⅳ were consistent with the assessment of ADHD by IVA-CPT (Kappa value=0.485, total coincidence rate=75.5%, P<0.000 1). Inattention subset scores of SNAP-Ⅳ were negatively correlated with the Full Scale Attention Quotient (FAQ) in IVA-CPT ( r=-0.71, P<0.000 1). Hyperactivity-impulsive subscale in the SNAP-Ⅳ and IVA-CPT were consistent in the assessment of hyperactivity-impulsive behavior (Kappa value=0.585, total coincidence rate=81.6%, P<0.000 1). Hyperactivity-impulse subset scores were negatively correlated with the Full Scale Response Control Quotient (FRCQ) in IVA-CPT ( r=-0.74, P<0.000 1). Conclusions:Both SNAP-Ⅳ and IVA-CPT have certain diagnostic potential of ADHD, showing good consistency and correlation.They can be both used to provide a more comprehensive diagnosis basis, thereby reducing the misdiagnosis rate and missed diagnosis rate of ADHD.
RESUMEN
Objective:To explore the differentially expressed genes in glioblastoma development and their functions and roles as to identify the target genes influencing biological behaviors of glioblastoma.Methods:Original gene expression profiles of GSE70231 dataset obtained from Gene Expression Omnibus database were screened for differentially expressed genes by GEO2R software. DAVID database was used to conduct gene ontology (GO) function analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis for these differentially expressed genes. STRING database was used to construct protein-protein interaction (PPI) network of these differentially expressed genes; target genes were selected from PPI network by cytoHubba and MCODE plug-ins; GEPIA online was used to analyze the expressions of target genes in glioblastoma and their influences in overall survival of glioblastoma patients (sample data collecting from The Cancer Genome Atlas database). Finally, the selected target genes were verified using RNA-seq dataset GSE50021 from human tissues.Results:Totally, 520 differentially expressed genes were identified, including 305 up-regulated genes and 215 down-regulated ones. GO analysis showed that the differentially expressed genes were mainly enriched in biological processes (signal transduction, cell adhesion, and positive regulation of cell proliferation), cytological components (extracellular exosomes, cytoplasm, and cytoplasmic membrane), and molecular function (protein binding). KEGG pathway enrichment analysis showed that the differentially expressed genes were mainly enriched in mitogen activated protein kinase signal pathway, proteoglycans in cancer, oxytocin signal pathway and calcium signal pathway. Totally, 17 target genes were selected by MCODE and cytoHubba plug-ins from the PPI network of differentially expressed genes; functional analysis and clinical sample verification showed 8 target genes ( VCAM1, SPP1, ITGB1, CTGF, VIM, ITGAV, COL1A1, and BCL2A1) could affect the biological behaviors of glioblastoma; the correlations of ITGAV, COL1A1, and BCL2A1 with glioma had been rarely reported, and GSE50021 dataset verified that their expressions in glioblastoma tissues were significantly higher than those in normal brain tissues ( P<0.05). Conclusion:These 8 target genes concluded from this research, especially BCL2A1, COL1A1 and ITGAV, may be important targets for exploring the pathogenesis, diagnosis and treatment of glioblastoma in the future.
RESUMEN
BACKGROUND: There is an inflammatory response in the lesion tissue of ischemic cerebral infarction, and the expression of miR-150-5p is significantly decreased. Whether miR-150-5p inhibits the release of inflammatory factors and alleviates the injury of ischemic cerebral infarction tissue through the Toll-like receptor-5/nuclear factor-KB pathway remains unclear. OBJECTIVE: To investigate the role and preliminary mechanism of miR-150-5p in ischemic cerebral infarction in rats. METHODS: (1) The rat models of middle cerebral artery occlusion were constructed and the rat models were divided into five groups: Control, miR-150-5p agomir, agomir control, miR-150-5p antagomir and antagomir control groups. (2) The rats in the control group was given the intracerebroventricular injection of normal saline, and the rats in the latter four groups were given the intracerebroventricular injection of miR-150-5p agomir (miR-150-5p agonist), agomir negative control, miR150-5p antagomir (miR150-5p inhibitor) and antagomir negative control, respectively. (3) After 7 days, the brain was graded by modified neurological severity score, the cerebral infarct volume was measured by MRI, and the histopathological changes were observed by hematoxylin-eosin staining. The expression levels of miR-150-5p, interleukin-6, tumor necrosis factor-a, Toll-like receptor-5 and nuclear factor-KB p65 in brain tissues were detected by qRT-PCR, ELISA and western blot assay, respectively. The target relationship between miR150-5p and Toll-like receptor-5 was verified by luciferase assay by retrieving the bioinformatics website Targetscan to predict the binding sites of miR-150-5p and Toll-like receptor-5. RESULTS AND CONCLUSION: (1) Compared with the control group, the modified neurological severity score, and levels of interleukin-6, tumor necrosis factor-a, Toll-like receptor-5 and nuclear factor-KB p65 proteins were significantly decreased in the miR-150-5p agomir group (P 0.05). (3) TargerScan website prediction results and luciferase reporter gene analysis results showed that miR-150-5p and Toll-like receptor-5 had a targeted binding site. (4) These results imply that miR-150-5p can inhibit the inflammatory signaling pathway of Toll-like receptor-5/nuclear factor-KB p65 in brain injury caused by ischemia and reduce the inflammatory response, thereby alleviating the damage of nerve function and playing a protective role.
RESUMEN
BACKGROUND: The placental tissue structure is complex, including the amniotic membrane, chorion, and decidua from the mother. Mesenchymal stem cells derived from different tissues of the same placenta have been reported to have similar biological characteristics. To date, there is no study regarding quantitative comparison of differentiation potential and immunomodulatory function of mesenchymal stem cells derived from different tissues of human placenta. OBJECTIVE: To investigate the biological characteristics including differentiation potential and immunomodulatory function of mesenchymal stem cells derived from different tissues of human placenta. METHODS: The amnion-, chorion-, and decidua-derived mesenchymal stem cells were isolated from the placental tissue of a baby boy by enzymatic digestion method. The biological characteristics of these three kinds of mesenchymal stem cells were systematically investigated including cell morphology, immunophenotypes, karyotypeanalysis, adipogenic and osteogenic differentiation potential, and Treg cells proliferation capacity. RESULTS AND CONCLUSION: All three kinds of mesenchymal stem cells showed fibroblast-like morphology and expressed the surface markers of mesenchymal stem cells with high expressions of CD73, CD90 and CD105, as well as low expressions of CD14, CD19, CD34, CD45 and HLA-DR. The karyotypes of the amnion-and chorion-derived mesenchymal stem cells were the same as the fetus, and decidua-derived mesenchymal stem cells had the same karyotype as the mother. There were significant differences in adipogenic differentiation capacity between three kinds of mesenchymal stem cells (amnion-derived mesenchymal stem cells> chorion-derived mesenchymal stem cells> decidua-derived mesenchymal stem cells; P < 0.05). In contrast, the osteogenic differentiation capacity of amnion-derived mesenchymal stem cells was remarkably higher than that of decidua-derived mesenchymal stem cells (P < 0.05). The amnion-and chorion-derived mesenchymal stem cells had the higher potential of Treg cell proliferation induction than decidua-derived mesenchymal stem cells. These findings indicate that three sources of human placenta-derived mesenchymal stem cells have different karyotypes, adipogenic and osteogenic differentiation potential, and immunomodulatory capability, providing a variety of ideal seed cell sources for disease treatment.

RESUMEN
PURPOSE: The purpose of this study is to investigate the impact of transitional care by a nurse-led multidisciplinary team (MDT) on clinical outcomes and quality of life of patients with ankylosing spondylitis. METHODS: A randomized control study design was used. Subjects were allocated randomly to an experimental group and a control group. The experimental group received intensive transitional care by a nurse-led MDT, whereas the control group received routine nursing care. Disease activity, spinal mobility, comprehensive function, health service utilization, and quality of life were assessed at the baseline and at six months with the Bath Ankylosing Spondylitis Metrology Index, the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), the Bath Ankylosing Spondylitis Functional Index (BASFI), a health service utilization questionnaire and version 2 of the Short Form-36 health survey. RESULTS: Compared with the baseline, the BASDAI, BASFI, emergency visits, hospitalizations, hospitalization days, and bodily pain, vitality, mental health, total score, and average score of version 2 of the Short Form-36 health survey were improved in the experimental group (p < .05), whereas only bodily pain, vitality, and role-emotional were improved in the control group p < .05). At six months, the experimental group exhibited significantly more improvement on the BASDAI, BASFI, hospitalizations, all domains except Role-physical as well as total score and average score p < .05) compared with the control group. CONCLUSION: A MDT-based nurse-led transitional care improves clinical outcomes and quality of life of patients with ankylosing spondylitis. Future research should be carried out on modes of follow-up and family support.

Objective To explore changes of brain function among patients with partial epilepsy in resting state by using the blood oxygenation level dependent functional magnetic resonance imaging (fMRI) techniques.Methods fMRI scanning was performed in resting state among 60 patients with partial epilepsy and 60 gender,age and educational levels matched normal controls.The functional connectivity analysis was applied to calculate the default mode network ( DMN ) functional connectivity in resting-state fMRI.SPM5 was used to analyze differences in functional connectivity between the two groups( P ＜0.001,cluster ＞50).Results Left precuneus and adjacent posterior cingulate cortex ( Pcu/PCC),angular gyrus,and cingulate gyrus were involved in the DMN of epileptic patients.By contrast,the DMN of controls included left Pcu/PCC,right angular gyrus,bilateral medial frontal lobe and temporal lobe.Compared with normal controls,patients with partial epilepsy showed a significantly decrease in functional connectivity of DMN region such as left inferior parietal lobule,supramarginal gyrus,parahippocampa gyrus and superior temporal gyrus,and bilateral uncus,while no regions were found increased functional connectivity in patients group.Conclusions Patients with partial epilepsy show abnormal changes in functional connectivity of DMN in resting state by fMR],which may associate with the potential pathophysiological mechanisms of epilepsy.The findings demonstrate that the resting-state fMRI might detect the extensive changes of brain function in partial epilepsy with negative results of conventional MRI,suggestive of fMRI as an effective and non-invasive method to explore brain function in epilepsy.
RESUMEN
Background and purpose: Paclitaxel is believed to be efficient in treating malignant ascites in gastric cancer. However, researches are still needed to get more evidence. The aim of this study was to discuss the efficacy and safety of the treatment of malignant ascites in gastric cancer with paclitaxel. Methods: Six cases of late phase gastric cancer patients were enrolled into the study, paclitaxel 60 mg/m~2 and 1 500-2 000 mL natural solution were administered via intraperitoneal injection, qw, for a of total 2-4 weeks. Efficacy and toxicity were determined according to WHO criteria. Results: Five (5/6) had complete response, and one (1/6) with partial response. The malignant ascites recession time was 0.5-10 months, overall survival time 2-10 months, 4 cases suffered grade Ⅰ-Ⅲabdominal pain, 4 cases grade Ⅰ leucopenia, 3 cases grade Ⅰ hair loss, 1 case grade Ⅰ liver injury (with past history of hepatitis). Conclusion: Paclitaxel is effective and relatively safe to treat malignant ascites of gastric cancer.
