		                        			Objective:To analyze the characteristics of inhibitory control and cognitive flexibility in hearing-impaired children.Methods:From March to April 2023, a convenience sampling method was used to select 33 hearing-impaired children from a special education school in Meizhou City, Guangdong Province, and 35 normal-hearing children from two ordinary schools as participants. Inhibitory control and cognitive flexibility of the participants were assessed by the Flanker task and the dimensional change card sorting (DCCS) task. Statistical analysis was conducted using SPSS 26.0 software, and independent sample t-test was used to compare the differences in reaction time and accuracy rate between two groups of participants. Results:There were no significant differences in the Flanker task reaction time ((558.39±123.65) ms vs (566.11±118.20) ms) and accuracy rate((0.93±0.10) vs (0.96±0.04))between hearing-impaired children and normal-hearing children ( t=-0.295, -1.645, both P>0.05). The hearing-impaired children had significantly longer reaction time ((1 019.60±131.08) ms)than the normal-hearing children ((857.85±129.19) ms) ( t=4.046, P=0.001) in the DCCS task, while there was no statistically significant difference in the accuracy rate between hearing-impaired children (0.62±0.16) and normal-hearing children (0.57±0.15) ( t=-1.602, P>0.05). Conclusion:There is no difference in inhibitory control ability between hearing-impaired children and normal-hearing children, but the hearing-impaired children have a lag in cognitive flexibility.

		                        			Objective:To investigate the effects of adherent-invasive Escherichia coli ( E. coli) LF82 on the structure and function of intestinal barrier in mice with ulcerative colitis (UC). Methods:Twenty-four specific pathogen free (SPF) C57BL/6 mice were divided into UC with E. coli LF82 group, UC group and healthy control group with eight mice in each group. The UC mice model was induced by dextran sulfate sodium (DSS). One week before modeling, the mice of UC with E. coli LF82 group were intragastric administrated with 1×10 9 colony-forming unit (CFU) E. coli LF82 to colonize the bacteria strain. The effects of E. coli LF82 on colitis of mice with UC were evaluated by disease activity index (DAI), gross morphological injury score, colonic mucosal injury index (CMDI), myeoloperoxidase (MPO) activity and pathological features. The ultrastructure and the changes of cytoskeleton F-actin of mice colonic tissues were detected by transmission electron microscope (TEM) and direct immunofluorescence. The ability of colonic mucin production and degree of fibrosis were estimated by periodic acid Schiff reaction (PAS) stain and sirius red stain. T test, least significant difference, repeated measurement analysis of variance and one-way analysis of variance were used for statistical analysis. Results:On the fourth, fifth, sixth and seventh day after the modeling, the DAI scores of UC with E. coli LF82 group were all higher than those of UC group ((2.53±0.38) points vs. (2.01±0.53) points, (3.02±0.62) points vs. (2.67±0.24) points, (3.13±0.61) points vs. (2.20±0.24) points, (3.27±0.28) points vs. (2.20±0.69) points, respectively), and the differences were statistically significant ( t=3.37, 2.25, 9.56 and 10.24, all P<0.05). The gross morphological injury score of mice colon of UC with E. coli LF82 group was higher than that of UC group ((6.17±1.94) points vs. (2.83±0.98) points), and the difference was statistically significant ( t=-3.75, P<0.05). The CMDI and MPO activity of UC with E. coli LF82 group were both higher than those of UC group ((16.80±2.79) points vs. (11.80±3.11) points, (729.3±77.5) U/mg vs. (594.4±31.9) U/mg), and the differences were statistically significant ( t=-2.83; mean difference=134.82, 95% confidence interval ( CI) 72.12 to 197.51; both P<0.05). The results of TEM showed that the E. coli LF82 could invade the submucosa of colon and caused further injury of colonic tissues in mice. The distribution of cytoskeleton F-actin of mice colonic tissues changed. The results of PAS staining showed that the percentages of PAS positive cells of UC with E. coli LF82 group and UC group were both lower than that of healthy control group ((32.40±8.02)% and (41.90±8.99)% vs. (57.70±11.52)%), and the difference was statistically significant ( F=17.63, P<0.01). The percentage of PAS positive cells of UC with E. coli LF82 group was lower than that of UC group, and the difference was statistically significant (mean difference=-9.50, 95% CI -18.33 to -0.67, P<0.05). The results of sirius red staining showed that the villous epithelium of colon mucosa of UC with E. coli LF82 group was partially injured and collagen fibers hyperplasia was serious. The area ratios of collagen fiber of UC with E. coli LF82 group and UC group were both higher than that of healthy control group ((51.83±5.78)% and (37.11±5.59)% vs. (15.41±2.25) %), and the difference was statistically significant ( F=86.72, P<0.01). The area ratio of collagen fiber of UC with E. coli LF82 group was higher than that of UC group, the difference was statistically significant (mean difference=14.83, 95% CI 8.91 to 20.76, P<0.05). Conclusions:E. coli LF82 can aggravate DSS-induced colitis in UC mice, leading to changes in colon ultrastructure and cytoskeleton, it can also reduce the ability of mucus secretion of colon of mice and increase the degree of colonic tissues fibrosis.

		                        			Objective:To examine the relationship between pre-pregnancy BMI, gestational diabetes (GDM) and different indicators of childhood obesity at the age of 4.Methods:Based on Ma’anshan Birth Cohort Study, singleton children who were born in Ma’anshan of Anhui province from October 2013 to April 2015, were followed for 4 years, consecutively. During the first questionnaire survey, data including pre-pregnancy weight, height and socio-demography were collected. During 24-28 week of gestation, 75 g oral glucose tolerance test was conducted for them. Childhood height, weight, waist circumference and body composition were measured at the age of 4. Comparisons between groups were performed using chi-square test, analysis of variance or t-test. The relationship between pre-pregnancy overweight/obesity, GDM and childhood obesity-related characteristics were analyzed by logistic regression model and generalized linear model analysis. Results:The prevalence rates of overweight and obesity in children at the age of 4 were 13.08% and 6.03%, respectively. After adjustment for characteristics related to mothers and their children, significantly increased risk of obesity ( OR=3.27, 95% CI: 2.15-4.98), larger waist circumference ( OR=2.32, 95% CI: 1.72-3.14) and higher waist-to-weight ratio ( OR=2.29, 95% CI: 1.73-3.02) were seen in the offspring of women with pre-pregnancy overweight/obesity. Body composition (skeletal muscle, body fat, body fat percentage) of the offspring were strongly correlated with pre-pregnancy overweight/obesity of the mothers ( P<0.05). Maternal GDM was associated with higher risk of childhood obesity ( OR=1.78, 95% CI: 1.14-2.79), on mothers without GDM during pregnancy. However, neither larger waist circumference, or higher waist-to-weight ratio seemed to increase the risk. Moreover, maternal GDM was not associated with body composition measures (skeletal muscle, body fat, body fat percentage). Conclusion:Pre-pregnancy BMI and maternal GDM were independent risk factors for obesity in 4-year-old children, and pre-pregnancy BMI was correlated with various indicators of body composition in children.

		                        			Objective To discuss the effect of applying internet-based formative evaluation in paediatric nursing teaching. Methods Three nursing classes from grade 2015 were selected as research subjects, and determined randomly as test group, control group 1 and control group 2. Internet-based formative evaluation was used in the test group, while control group 1 used traditional test papers, and control group 2 skipped formative evaluation. Results Analysis of the results and the total scores of the final examination showed no significant difference between the test group and the control group 1 (P>0.05), but the scores of both groups were significantly higher than that of the control group 2 (P<0.05). The scores of the students' evaluation to teachers in test group was better than that in control group 1 and control group 2, and the differences between the three groups were statistically significant (P<0.05). The average time of exams in the test group was shorter than that of control group 1, and the difference between the two groups was statistically significant (P<0.05). The cost of the test group was 0 yuan, while the cost of the control group1 was 638 yuan. Conclusion Although there is no significant difference in the teaching effect between the internet-based formative evaluation and traditional test papers , internet-based tests can significantly improve the students' interest in learning, increase the efficiency of teaching and learning, and improve the teaching quality . The internet-based formative evaluation can be widely used in nursing teaching.
