Objective:To explore the interaction between pediatric sleep-disordered breathing（SDB）, the intestinal microbiota, and pediatric non-alcoholic fatty liver disease（NAFLD）. Methods:A total of 63 non-obese children（47 children with SDB in the experimental group and 16 without SDB in the control group） were enrolled in this study. The liver function and degree of SDB were assessed in both groups. High-throughput 16S rRNA sequencing was conducted to detect the composition and functional variations of the intestinal microbiota in the two groups of children. Results:Compared with children in the experimental group, serum ALT and AST levels were higher in the control group. and the relative proteobacteria abundance of intestinal flora increased, and the relative abundance of Bacteroidetes decreased significantly. Function including membrane transport, carbohydrate metabolism and lipid metabolism, were enriched in the intestinal microbiota of children with SDB. Conclusion:The composition and functional annotation of the pediatric liver functional status and gut microbiota were significantly different between the two groups of children with and without SDB. Changes in SDB-associated intestinal bacterial abundance may be related to the pathogenesis of pediatric NAFLD.

Objective: To discuss the effect of psychological nursing based on relaxation training for the psychological state in patients with impatced third molar removal surgery. Methods: A total of one hundred patients with impacted third molar removal surgery were selected from June 2015 to June 2017 in People's Liberation Army No. 105 hospital. According to the nursing method, all patients were divided into psychological intervention group and the control group, 50 cases in each group, the control group was given routine nursing intervention and the psychological intervention group was given psychological nursing intervention based on relaxation training. Results: The after intervention Corah's modified dental anxiety scale (6.3±1.2), Stouthard dental fear scale (62.9±6.5) scores and heart rate [(76.4±5.2) bpm], systolic blood pressure [(102.5±6.3) mmHg], diastolic blood pressure [(75.3±3.1) mmHg] levels of psychological group were significantly lower than those of the control group. The once removal success rate, intraoperative relaxation sense rate of psychological group were significantly higher than those of the control group, the teeth extraction time of psychological group was significantly lower than that of the control group, the difference was statistically significant (P=0.013, P=0.003). Conclusions Psychological nursing intervention based on relaxation training can effectively improve the mental state and stress state of patients with impacted third molar removal surgery, which is beneficial to the process of the surgery.
