Efficacy of bronchoalveolar lavage combined with prone positioning in children with Mycoplasma pneumoniae pneumonia and atelectasis: a prospective randomized controlled study / 中国当代儿科杂志

OBJECTIVES@#To study the efficacy of bronchoalveolar lavage (BAL) combined with prone positioning in children with Mycoplasma pneumoniae pneumonia (MPP) and atelectasis and its effect on pulmonary function.@*METHODS@#A prospective study was conducted on 94 children with MPP and atelectasis who were hospitalized in Ordos Central Hospital of Inner Mongolia from November 2020 to May 2023. The children were randomly divided into a treatment group and a control group, with 47 children in each group. The children in the treatment group were given conventional treatment, BAL, and prone positioning, and those in the control group were given conventional treatment and BAL. The two groups were compared in terms of fever, pulmonary signs, length of hospital stay, lung recruitment, and improvement in pulmonary function.@*RESULTS@#Compared with the control group, the treatment group had significantly shorter time to improvement in pulmonary signs and length of hospital stay and a significantly higher rate of lung recruitment on day 7 of hospitalization, on the day of discharge, and at 1 week after discharge (P<0.05). Compared with the control group, the treatment group had significantly higher levels of forced vital capacity (FVC) as a percentage of the predicted value, forced expiratory volume (FEV) in 1 second as a percentage of the predicted value, ratio of FEV in 1 second to FVC, forced expiratory flow at 50% of FVC as a percentage of the predicted value, forced expiratory flow at 75% of FVC as a percentage of the predicted value, and maximal mid-expiratory flow as a percentage of the predicted value on the day of discharge and at 1 week after discharge (P<0.05). There was no significant difference in the time for body temperature to return to normal between the two groups (P>0.05).@*CONCLUSIONS@#In the treatment of children with MPP and atelectasis, BAL combined with prone positioning can help to shorten the time to improvement in pulmonary signs and the length of hospital stay and promote lung recruitment and improvement in pulmonary function.

Reliability and validity of the Chinese version of tolerance for mental pain scale for college students / 中华行为医学与脑科学杂志

Objective:To examine the reliability and validity of tolerance of mental pain scale (TMPS-10) in college students.Methods:A total of 2 171 college students were recruited in this study from November to December 2021.Sample 1( n=1 085) was tested for item analysis and exploratory factor analysis from November to December 2021.Sample 2 ( n=1 086) was tested for confirmatory factor analysis, convergence validity, and criterion validity analysis.Ninety-nine cases were randomly selected from sample 2 for retest intraclass correlation efficient (ICC) 30 days later.The questionnaire of suicide attitude (QSA), Beck depression inventory version 2 (BDI-Ⅱ), self-rating anxiety scale (SAS), and Chinese perceived stress scale (CPSS) were used to examine criterion validity of TMPS-10.The SPSS 25.0 and AMOS 21.0 softwares were used for statistical analysis. Results:The exploratory factor analysis extracted two common factors, which explained 72.33% of the total variance contribution rate.The confirmatory factor analysis showed a good model fit ( χ2/ df=7.85, AGFI=0.92, GFI=0.95, TLI=0.96, CFI=0.97, IFI=0.97, RMSEA=0.08). The combined reliability (CR) of the Chinese version of TMPS-10 and its two factors were 0.96, 0.93 and 0.89, and the average variances extracted (AVE) were 0.72, 0.73 and 0.63.The total score of TMPS-10 was positively correlated with the two dimensions of QSA (knowledge of the nature of suicide behavior and attitude to euthanasia) ( r=0.40, 0.09, both P<0.01), while was negatively correlated with the other two dimensions of QSA (attitude to suicide and attitude to suicide family members), and the total scores of BDI-Ⅱ, SAS, and CPSS ( r=-0.30, -0.34, -0.30, -0.45, -0.46, all P<0.01). The Cronbach α coefficients of the Chinese version of TMPS-10 and its two factors were 0.82, 0.89 and 0.93, and the spilt-half reliabilities were 0.85, 0.89 and 0.89.The ICC of the Chinese version of TMPS-10 and its two factors after 30 days were 0.77, 0.87 and 0.86. Conclusion:The Chinese version of TMPS-10 has good reliability and validity among college students, and it can effectively evaluate students' endurance of psychological pain.
