Executive function characteristics of preschool children with high functioning autism and children with global developmental delay / 中华行为医学与脑科学杂志

Objective:To investigate the characteristics of executive function of preschool children with high functioning autism spectrum disorder (HFA) and with global developmental delay (GDD), and the differences among HFA, GDD and typically developmental (TD) children.Methods:From January 2020 to January 2021, 20 male HFA, 20 male GDD and 20 male TD children aged 4-6 years who visited the Psychological Behavior Clinic of the Child Health Department of Guiyang Maternal and Child Health Hospital and the Developmental Behavior Clinic of the Children Health Department of the Ninth People's Hospital in Chongqing were selected for comparative study.The executive function of HFA, GDD and TD children was assessed with the behavior rating scale of executive function-preschool version(BRIEF-P) and the executive function task program (EF-TOUCH). SPSS 26.0 software was used for statistical analysis, including variance test, independent sample t-test, χ2 test, Kruskal Wallis test and Mann-Whitney U test. Results:In the EF-TOUCH program task, the accuracy of the three groups of children's performance in the pig task (Pig), the silly sounds game (SSG), the working memory task (pick the picture, PTP) and the task of cognitive flexibility (something's the same, STS) were statistically different(Pig: HFA group: 0.87(0.76, 0.99), GDD group: 0.97(0.85, 0.99), TD group: 1.00(0.98, 1.00), χ2=15.646, P<0.001; SSG: HFA group: 0.76(0.53, 0.91), GDD group: 0.76(0.65, 0.99), TD group: 0.94(0.76, 1.00), χ2=6.448, P=0.040; PTP: HFA group: 0.66±0.18, GDD group: 0.66±0.19, TD group: 0.78±0.11; F=3.221, P=0.048; STS: HFA group: 0.67(0.63, 0.70), GDD group: 0.72(0.46, 0.78), TD group: 0.87(0.83, 0.90), χ2=26.898, P<0.001). The accuracies of Pig, SSG, PTP and STS in HFA group were significantly lower than those in TD group(all P<0.05), and the accuracies of Pig and STS in GDD group were significantly lower than those in TD group(both P<0.05). In inhibition control, there were statistically differences in response time of Pig and SSG among the three groups (Pig: HFA group: (1 694.36±222.83)ms, GDD group: (1 513.46±244.91)ms, TD group: (1 444.84±197.95)ms, F=5.810, P=0.005; SSG: HFA group: (2 202.42±195.58)ms, GDD group: (2 116.52±323.27)ms, TD group: (1 937.17±252.74)ms, Z=4.610, P=0.014). There were no significant differences in the reaction time of Arrows task ( P>0.05). There were significant differences in BRIEF-P inhibition control, organizational planning, inhibition self-regulation, cognitive flexibility and total scores among the three groups ( P<0.05), while there were no significant differences in the scores of other factors and dimensions ( P>0.05). Conclusion:The executive function of pre-school children with high functioning autism spectrum disorder and children with global developmental delay is impaired.The executive function of children with high functioning autism spectrum disorder and children with global developmental delay is significantly different from that of typically developmental children of the same age.Moreover, the executive function of children with HFA is more severely damaged from all components than that of children with GDD.

Comparison of executive function between preschool-aged male children with high functioning autism and typically developing children / 中华行为医学与脑科学杂志

Objective:To discuss the executive function (EF) characteristics of preschool aged male children diagnosed as high-functioning autism (HFA), and to compare the EF differences between HFA and typically developing (TD) children.Methods:Twenty-six preschool male HFA children aged 4-5 years old and chronological age and gender matched TD children were recruited respectively. Parent questionnaire behavior rating scale of executive function-preschool version (BRIEF-P) and executive function battery EF-TOUCH were adopted to explore the EF characteristics and the differences between the two groups. SPSS 22.0 software was used for statistical analysis, including descriptive statistics, χ2 test, t-test and Mann-Whitney U test. Results:EF-TOUCH results demonstrated significant differences with correct proportions of inhibition tasks (Arrow, Pig, silly sounds game (SSG)), working memory task (pick the picture (PTP)) and cognitive flexibility task (something′s the same (STS)) between groups (Arrow: Z=-2.278, P=0.023; Pig: Z=-2.599, P=0.009; SSG: Z=-1.985, P=0.047; PTP: t=2.635, P=0.011; STS: Z=-3.556, P=0.000). The accuracy rate in HFA group were significantly lower than TD group (HFA group: Arrow: 0.76 (0.57, 0.92), Pig: 0.95 (0.90, 1.00), SSG: 0.85 (0.57, 0.94), PTP: 0.74±0.11, STS: 0.77 (0.62, 0.90); TD group: Arrow: 0.92 (0.78, 0.95), Pig: 1.00 (0.98, 1.00), SSG: 0.94 (0.82, 1.00), PTP: 0.81±0.09, STS: 0.93 (0.82, 0.97)). Reaction time(RT) of Pig task was longer in HFA group than TD group (HFA: (1 624.29±234.33)ms; TD: (1 481.39±220.78)ms, t=-2.263, P=0.028). RTs of Arrow and SSG for both groups were not significantly different ( P>0.05). Children of HFA group exhibited worse inhibition and working memory(WM) than TD children in BRIEF-P(inhibition: HFA group (60.73±10.47), TD group (54.73±6.87); WM: HFA group (68.04±11.51), TD group (61.69±8.44))( t=-2.443, P=0.018; t=-2.267, P=0.028 respectively). No significant differences were found in the rest factors and domains for both groups (all P>0.05). Conclusions:Apparent inhibition control, working memory and cognitive flexibility deficiencies were found in preschool aged male HFA children. There are significant EF differences between preschool aged male HFA and typically developing children.

Effects of Transcranial Direct Current Stimulation over Vagus Nerve on Dysphagia after Stroke / 中国康复理论与实践

Objective:To study the effect of transcranial direct current stimulation (tDCS) regulating excitability of the vagus nerve on dysphagia after stroke. Methods:From September, 2020 to February, 2021, 28 patients with dysphagia after stroke were randomly divided into control group (n = 14) and tDCS group (n = 14). Both groups accepted swallowing function training, and tDCS group received anodal tDCS over vagus nerve, while the control group received sham tDCS. They were assessed with modified Mann Assessment of Swallowing Ability (MMASA) and Australian Therapy Outcome Measures (AusTOMs)-swallowing scale before and after treatment. Results:The scores of MMASA (|t| > 5.593, P < 0.001) and AusTOMs swallowing scale (|Z| > 2.121, P < 0.05) increased in both groups after treatment, and were higher in tDCS group than in the control group (|t| = 2.439, |Z| = 2.079, P < 0.05). Conclusion:Anodal tDCS over vagus nerve may further release dysphagia after stroke.

Inflammatory pseudotumor-like follicular dendritic cell tumor of spleen / 中华病理学杂志

<p><b>OBJECTIVE</b>To study the clinicopathologic features of inflammatory pseudotumor-like follicular dendritic cell tumor of spleen.</p><p><b>METHODS</b>One case of inflammatory pseudotumor-like follicular dendritic cell tumor of spleen was examined macroscopically and microscopically. Immunohistochemical study for CD21, CD23, CD35, clusterin, S-100 protein, vimentin, smooth muscle actin, CD1a, CD68, ALK protein, CD30, CD31, CD34, CD3 and CD20 was performed on formalin-fixed, paraffin-embedded sections by standard EnVision method. In-situ hybridization for Epstein-Barr virus (EBV)-encoded RNA was also carried out.</p><p><b>RESULTS</b>Macroscopically, inflammatory pseudotumor-like follicular dendritic cell tumor was large in size, tan-colored, soft to rubbery in consistance and associated with central hemorrhage and necrosis. Histological examination showed scattered follicular dendritic cells admixed with abundant lymphocytes and plasma cells in the background, simulating inflammatory pseudotumor. On high-power magnification, the follicular dendritic cells possessed a moderate amount of pale to lightly eosinophilic cytoplasm, with indistinct cell borders. The nuclei were ovoid or spindly, with vesicular or stippled chromatin and small distinct, often centrally located, nucleoli. Some of the tumor cells showed nuclear pleomorphism and contained irregular foldings of nuclear membrane, coarse chromatin and prominent eosinophilic nucleoli. Mitotic figures were rarely identified. Immunohistochemical study showed that the tumor cells were positive for vimentin, clusterin, smooth muscle actin and CD68. They were weakly and focally positive for CD35 and S-100 protein, but negative for CD21, CD23, CD1a, ALK protein, CD30, CD31 and CD34. Most of the background lymphocytes were of T-lineage (CD3-positive) ,some were CD20 (B-cell marker)-positive. EBV RNA was demonstrated in the tumor cells by in-situ hybridization analysis.</p><p><b>CONCLUSIONS</b>Inflammatory pseudotumor-like follicular dendritic cell tumor is a rarely encountered low-grade malignancy with distinctive morphologic pattern. It is associated with EBV infection.</p>

Synergetic transactivating effect of HCV core and HBV X proteins on SV40 early promoter/enhancer / 中华实验和临床病毒学杂志

<p><b>BACKGROUND</b>To investigate the synergetic transactivating effects of HCV core and HBV X proteins.</p><p><b>METHODS</b>HCV core and HBV X protein-expressing plasmids were constructed with the vector pcDNA3.1(-). The plasmids were transfected into HepG2 cells and cotransfected Hep2 cells with reporter plasmid Psv-lacZ by lipofectamine plus reagents. The virus proteins produced in transient expression system were detected at the transcription and translation levels. The activity of b-galactosidase was detected, which reflected the transactivating function of the proteins.</p><p><b>RESULTS</b>The expression of plasmids were detected in soluble protein cell extracts of transiently transfected HepG2 cells. HCV core protein activated the b-galactosidase expression at a value 4.9 times higher than the control, while HBV X protein activated at a value 3.5 times. It arrived at 9 times transfected with the plasmids simultaneously. The activating effect increased in relation to the amount of plasmids.</p><p><b>CONCLUSIONS</b>The results suggested that the two kinds of virus proteins have transactivating effect on SV40 early promoter/enhancer, and they acted synergistically. These contribute to explain the mechanisms of liver injury or tumorigenesis induced by HCV or/and HBV infection.</p>
