Assessment of Nervous System of High-risk Infants: 236 Cases Report / 中国康复理论与实践

Objective:To investigate evaluation methods to predict the outcome of nervous system development in high-risk infants. Methods:From March, 2015 to March, 2016, 336 high-risk infants were enrolled. They were assessed by General Movements (GMs) Quality Assessment, 0~1 Years Old 20 Items Neuromotor Assessment and Gesell Developmental Schedules. Results:A total of 236 infants finishied the study. GMs Quality Assessment showed that 203 cases were normal and 33 cases were abnormal in the writhing movements stage; 218 cases were normal and 18 cases were abnormal in the fidgety movemonts stage. 0~1 Years Old 20 Items Neuromotor Assessment showed that 202 cases were normal and 34 cases were abnormal. Gesell Developmental Schedules showed that 12 cases were abnormal. Conclusion:The combination of GMs Quality Assessment, 0~1 Years Old 20 Items Neuromotor Assessment and Gesell Developmental Schedules could better predict the nervous system development of high-risk infants.

Endogenous glucocorticoid increases the basal level of Treg-Th17 balance under early phase of stress / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>To explore the changes of Treg-Th17 balance influenced by corticosterone, major effect hormone of hypothalamic-pituitary-adrenal (HPA) axis under running stress.</p><p><b>METHODS</b>A total of 25 corticotropin-releasing hormone (CRH) wildtype (CRH+/+) and knockout (CRH-/-) mice were adopt and divided into 4 groups as follows: CRH+/+ ctrl, CRH+/+ stress, CRH-/- ctrl and CRH-/- stress. All mice in stress groups were under 2 h running. After 1 h, blood plasma in all groups was collected and the expression of corticosterone and IL-17A was detected by ELISA. Meanwhile, unicell suspensions of peripheral lymph node and spleen in each group were prepared too and stained by PE-CD4 and FITC-CD25, then the changes of Treg (CD4+CD25+) in different groups were checked by flow cytometry; all data were statistically analyzed by the software of WinMDI 2.9, SPSS 11.5, Origin 7.5 and Matlab 2-D and 3-D plot function.</p><p><b>RESULTS</b>The levels of corticosterone were significantly higher in stress groups than that in corresponding control groups (P less than 0.05), especially in CRH+/+ stress group (P less than 0.01). However, the changes of Tregs were not obvious between stress groups and control groups with respective genotypes (P less than 0.05). Compared with that in CRH+/+ control group, the ratio of Treg and the expression of IL-17A in CRH-/- stress group were significantly higher than those in control group (P less than 0.05). Combined with the expression levels of corticosterone, Treg and Th17, our study suggests that endogenous glucocorticoid with basal level may cause the changes in Treg-Th17 balance. Moreover, as the corticosterone level increases, the expression of Treg and Th17 appears to manifest antagonistic fluctuant status with a rising tendency in general.</p><p><b>CONCLUSION</b>Endogenous glucocorticoid under early stage of stress may increase the function of T lymphocyte immunity to some extent.</p>
