Objective:To investigate the effect of play therapy-based group counseling on behavior disorders and mental coping of school-age nephrotic syndrome children.Methods:A total of 140 school-age nephrotic syndrome children were randomly divided into experiment group ( n=70) and control group ( n=70). Children in the control group recieved routine care, while experiment group carried out play therapy-based group counseling based on the routine care. With the Conners Parent Symptom Questionnaire (PSQ) and Coping with a Disease (CODI), the overall curative effect was assessed before and after intervention by their scores. Results:After intervention, the incidence rate of behavior disorder of nephrotic syndrome children in the experiment group was 18.0% (11/63), lower than in the control group 33.8% (23/68), the difference was statistically significant ( χ2 value was 4.131, P=0.042). The conduct, psychosomatic disorder and hyperactivity index scores in the experiment group were (1.12±0.23), (0.24±0.08), (1.22±0.32) pionts, lower than (1.25±0.31), (0.29±0.09), (1.39±0.37) pionts in the control group, the difference was statistically significant ( t values were 2.625, 2.950, 2.825, P<0.05); the scores of acception, escape, negative feelings and total CODI scores were (12.87±3.19), (22.51±5.24), (25.83±4.51), (101.23±11.48) pionts, higher than (11.27±3.77), (20.41±4.00), (24.13±4.38), (95.38±8.33) pionts in the control group, the difference was statistically significant ( t values were 2.191-3.361, P<0.05). Conclusion:Play therapy-based group counseling can effectively alleviate behavior disorders and improve mental coping of school-age nephrotic syndrome children.

Objective: To create a model to predict nosocomial infections in emergency intensive care units (EICU), so as to provide insights into early identification and interventions among patients with nosocomial infections. Methods: All nosocomial infections were collected from patients hospitalized in the EICU of a large tertiary hospital from 2017 to 2020. The 2017-2019 data were selected as the training set to create a logistic regression model, and the fitting effectiveness of the predictive model was evaluated using Hosmer-Lemeshow test. The 2020 data were selected as the test set to evaluate the external validation of the predictive model. In addition, the value of the model for prediction of nosocomial infections was examined using the receiver operating characteristic (ROC) curve analysis. Results : Totally 1 546 inpatients in EICU were enrolled, and the prevalence of nosocomial infections was 7.18%. Multivariable logistic regression analysis identified hospital stay duration of >7 days (OR=21.845, 95%CI: 7.901-60.398), use of ventilators (OR=3.405, 95%CI: 1.335-8.682), and surgery (OR=1.854, 95%CI: 1.121-3.064) as risk factors of nosocomial infections. The predictive model was p=ey/(1+ey), y=-6.105+(3.084×duration of hospital stay)+(1.225×use of ventilators)+(0.617×surgery). The area under ROC curve was 0.806 (95%CI: 0.774-0.838) for the training set and 0.723 (95%CI: 0.623-0.823) for the test set, and if the 0.065 cut-off of the predictive model created by the training set was included in the test set, the predictive value yield a 0.739 sensitivity and 0.642 specificity for prediction of nosocomial infections among patients hospitalized in EICU. Conclusion The created predictive model for nosocomial infections among patients hospitalized in EICU presents a high accuracy, which shows a satisfactory predictive value for high-risk nosocomial infections.

Objective:To explore the effect of family-centered nursing model in the nursing of children with primary nephrotic syndrome (PNS) .Methods:From January 2018 to December 2019, convenience sampling was used to select 120 children with PNS admitted to the Children 's Hospital of Nanjing Medical University as the research object. According to the order of hospitalization, children were divided into the observation group and the control group, each with 60 cases. The control group conducted the routine nursing, and the observation group carried out the family-centered nursing model on the basis of the control group. The remission rate, recurrence rate and overall satisfaction of nursing care were compared between the two groups of children, and the Inventory of Subjective Life Quality (ISLQ) was used to evaluate the quality of life. Results:After intervention, the recurrence rate of children in the observation group was 5.00% (3/60) , which was lower than 16.67% (10/60) in the control group, and the difference was statistically significant ( P<0.05) . There was no significant difference in the remission rate of the two groups of children ( P>0.05) . After the intervention, the cognition level, emotional level, and overall level scores of the observation group were higher than those of the control group, and the differences were statistically significant ( P<0.05) . The nursing satisfaction of children in the observation group was 95.00% (57/60) , which was higher than 76.67% (46/60) in the control group, and the difference was statistically significant ( P<0.05) . Conclusions:Family-centered nursing can effectively improve the quality of life of children with PNS, reduce the recurrence rate, and improve nursing satisfaction. It is worthy of clinical application.

Objective To evaluate the performance of modified Hodge test on the detection of carbapenemases among Enterobacteriaceae with decreased susceptibility to carbapenems. Methods Fortynine Enterobacteriaceae isolates with decreased susceptibility to carbapenems ( MIC of imipenem, meropenem or ertapenem was ≥ 2 μg/ml ) were collected from 16 teaching hospitals from 2004 to 2008. MICs of imipenem, meropenem and etapenem were determined by agar dilution method. Carbapenemases were detected by modified Hodge test. Carbepenemase-causing positive results and AmpCs-causing positive results were differentiated by phenyl boronic acid and oxacillin. Beta-lactamases encoding genes including blaNDM-1were detected by PCR and sequencing. Results Thirty-six of 49 isolates were non-susceptible to imipenem (MIC >4 μg/ml), 31 were non-susceptible to meropenem (MIC > 4 μg/ml) and 47 were non-susceptible to ertapenem (MIC > 2 μg/ml). Twenty-three isolates showed positive modified Hodge test result, including 9 weak-positive results and 14 strong-positive results. Through PCR detection and sequencing, 2 out of 9 isolates showing weak-positive results carried blaKPC-2 and other 7 did not carry any carbapenemase genes but AmpCs/ESBLs genes. Among the 14 isolates showing strong-positive results, 4 carried blaKPC-2, 8 carried blaIMP-4 and 2 caried blaIMP-8. All 26 isolates with negative modified Hodge test result didn't carry any carbapenemase genes. No isolate carried blaNDM-1. Carbapenemases genes PCR detection was regarded as a gold standard, and the sensitivity, specificity, positive predictive value and negative predictive value of modified hodge test was 100%, 79%, 70% and 100% on the detection of carbapenemases among Enterobacteriaceae with decreased susceptibility to carbapenems. Conclusions Modified Hodge test revealed great sensitivity but showed a few false positive results. True and false positive results can be effectively differentiated by phynel boronic acid and oxacillin.
