Objective To investigate the influencing factors of airway mucosal erosion occurrence in child Mycoplasma pneumoniae pneumonia.Methods The medical record data of 162 children patients with Mycoplasma pneumoniae pneumonia hospitalized in the pediatric department of this hospital from February 2023 to February 2024 were analyzed retrospectively.The patients were divided into the mucosal erosion group(n=43)and non-mucosal erosion group(n=119)according to whether or not the mucosal erosion was ob-served by the bronchoscope.The general data,laboratory examination and lung ultrasound images data in the two groups were collected.The pulmonary ultrasound(LUS)was scored.The clinical characteristics,experi-mental indexes and LUS score were compared between the two groups.The stepwise logistic regression was used to analyze the influencing factors of airway mucosal erosion occurrence in Mycoplasma pneumoniae pneu-monia.The receiver operating characteristic(ROC)curve was drawn to analyze the diagnostic efficiency.Results There were statistically significant differences in the fever duration,fever peak,pleural effusion,hos-pitalization duration,neutrophil ratio,levels of C-reactive protein(CRP),lactate dehydrogenase(LDH)and D-dimer,and LUS score had statistical differences between the two groups(P<0.05).The multivariate logistic regression analysis results showed that the fever duration,neutrophil ratio,LDH,D-dimer and LUS score were the influencing factors for airway mucosal erosion occurrence in Mycoplasma pneumoniae pneumonia.The fe-ver duration,neutrophil ratio,LDH,D-dimer and LUS score all had certain predictive value for airway mucosal erosion occurrence in Mycoplasma pneumonae pneumonia,in which the area under the curve(AUC)of LDH,D-dimer and LUS score was larger,and the predictive value was higher(P<0.05).Conclusion The influen-cing factors of airway mucosal erosion in children patients with Mycoplasma pneumoniae pneumonia should be vigilant to improve their prognosis.

Objective To explore the reliability and validity of Meadow-Kendall Social-Emotional Assessment Inventory (SEAI) for Deaf and Hearing-Impaired Students Preschool Version in China. Methods 96 hearing-impaired children were assessed with SEAI, and 30 of them were assessed with Conners Teacher Rating Scale (TRS), 30 by another teacher, 30 by the first teacher 2 weeks later. The data were analyzed with Pearson's or Spearman's correlation analysis. Results For sociable communicative behaviors, impulsive dominating behaviors, developmental lags, anxious compulsive behaviors, items related to deafness, test-retest reliability (correlated coefficient, r) was 0.94,0.55, 0.87, 0.31, 0.74; and Cronbach's α was 0.70, 0.76, 0.76, 0.80, 0.68. The inter-rater reliability was 0.90, 0.58, 0.46, 0.14, 0.55. The subscales of SEAI were correlated (r=-0.36~-0.89, P<0.05) with the subscales of TRS. Confirmatory factor analysis showed that the subscale model of SEAI was reasonable. Conclusion The SEAI for Deaf and Hearing-impaired Students Preschool Version can be used for Chinese hearing-impaired children.

Objective To study the characteristics of language function development and establish the reference standards in children of4~6 years old. Methods 616 hearing normal children at the age of 3~7 from 13 provinces in China were assessed with Language FunctionEvaluation for Hearing-impaired Children. 583 usable data were analyzed via SPSS 17.0. Results The older the children were, the highertheir scores of language function evaluation were (P<0.001). The differences between boys and girls on coordination function and relaxationfunction were significant (P<0.01). The girls were better than the boys. The reference standards of children of 4~6 years old were set downbased on the regression analysis. Conclusion There are some laws on children's language function development. The reference standards ofchildren by 4~6 years old has been developed.
