ABSTRACT
OBJECTIVE@#To study the value of amplitude-integrated EEG (aEEG), Full Outline of Unresponsiveness (FOUR), and Glasgow Coma Scale (GCS) in evaluating the prognosis of children with disturbance of consciousness in the pediatric intensive care unit (PICU).@*METHODS@#A total of 164 children with disturbance of consciousness who were admitted to the PICU of Children's Hospital Affiliated to Soochow University were enrolled as subjects. According to prognosis, they were divided into a poor prognosis group with 111 children and a good prognosis group with 53 children. The results of aEEG monitoring, FOUR score, and GCS score on days 1 and 5 of admission were collected. The association between evaluation methods and prognosis was analyzed. The receiver operating characteristic (ROC) curve was used to evaluate the value of aEEG, FOUR, and GCS in predicting prognosis.@*RESULTS@#The children with no improvement or abnormal aggravation of aEEG on day 5 tended to have a poor prognosis. The results of aEEG was positively correlated with prognosis (r=0.689, P0.05), while aEEG combined with FOUR had an AUC of 0.945, which was significantly larger than that of each index alone (P<0.05).@*CONCLUSIONS@#Both aEEG and FOUR can be used as effective tools to predict the prognosis of children with disturbance of consciousness, and a combination of aEEG and FOUR can improve the predictive value.

OBJECTIVE@#To study the predictive value of Pediatric Age-adapted Sequential Organ Failure Assessment Score (pSOFA), Pediatric Risk of Mortality Score III (PRISM III), and Pediatric Critical Illness Score (PCIS) in children with severe sepsis.@*METHODS@#A retrospective analysis was performed for the clinical data of 193 hospitalized children with severe sepsis. According to the final outcome, these children were divided into a survival group with 151 children and a death group with 42 children. The scores of pSOFA, PRISM III, and PCIS were determined according to the worst values of each index within 24 hours after admission. The receiver operating characteristic (ROC) curve was used to analyze the efficiency of each scoring system in predicting the risk of death due to sepsis. Smooth curve fitting was used to analyze the correlation between the three scoring systems and the threshold effect of each scoring system. Decision curve analysis (DCA) was used to evaluate the application value of each scoring system.@*RESULTS@#The ROC analysis showed that PCIS and pSOFA had a similar predictive value (P=0.182) and that PRISM III and pSOFA had a similar predictive value (P=0.210), while PRISM III had a better predictive value than PCIS (P=0.045). PRISM III had the highest degree of fitting with prognosis, followed by pSOFA and PCIS. The DCA analysis showed that when the risk of death was 0.4 and 0.6 in children with severe sepsis and the three scoring systems were used as the basis for emergency intervention decision-making, pSOFA achieved the highest standardized net benefit, followed by PRISM III and PCIS.@*CONCLUSIONS@#All three scoring systems have a certain value in predicting the prognosis of children with severe sepsis, and pSOFA has a better value than PRISM III and PCIS.

Objective To investigate the value of pulmonary ventilation/ perfusion (V/ Q) SPECT in evaluation of anticoagulant therapy for patients with pulmonary embolism (PE) and identify factors which may affect the therapy. Methods From July 2014 to December 2016, sixty-three patients (23 males, 40 females, age (60±14) years), who were clinically diagnosed as PE and underwent V/ Q SPECT before and after anticoagulant therapy, were recruited retrospectively in this study. According to the percentage of lung perfusion defect (PD) out of total lung volume, the patients were divided into mild (<20％) PE, moderate (20％-50％) PE, and severe (>50％) PE groups. The lung PD decreased≥50％ after anticoagulant thera-py and no new PD detected was defined as the standard of effective therapy, otherwise the treatment were defined as ineffective. Data of different groups were compared. Factors that may predict the severity of PD or affect the treatment were analyzed. χ2 test and logistic regression were used for data analysis. Results PE were detected in 476 pulmonary segments and sub segments. The distribution of PE in different lung lobes had no statistically significant difference ( χ2 = 4. 995, P > 0. 05). More pulmonary arterial hypertension (PAH) were detected in patients with severe PE (80％, 12/ 15) and moderate PE (66.7％,16/ 24) in comparison with patients with mild PE (41.7％,10/ 24; χ2 = 7.062, P<0.05). The occurrence of PAH was related to the severity of PD, with odds ratio (OR) value of 2.680 (95％ CI: 1.115-6.446, P<0. 05).PAH was an independent risk factor for treatment effect (OR value: 3.134(95％ CI: 1.341-7. 324), P<0. 05). Conclusions V/ Q SPECT has an important value for evaluating the effect of anticoagulant therapy and guiding individual therapy. The more extent of PE involved, the higher prevalence of PAH. Anticoagu-lant therapy may be ineffective in PE patients with moderate or severe PAH.
ABSTRACT
BACKGROUND: Amniotic membrane has a unique structure that can block the penetration of certain substances, to ensure normal nutrition supply for the surrounded tissues, and is also characterized by anti-adhesion, good tissue compatibility, mild inflammatory reaction, few fibers and biodegradability. OBJECTIVE: To compare the effects of fresh amniotic membrane and acellular amniotic membrane to prevent adhesion and promote tendon healing during the repair of tendon sheath defects. METHODS: Sixty healthy male leghorn chickens were selected, and the model of tendon injury and tendon sheath defects was established at the third toes. The animal models were then randomly divided into three groups and underwent repair with fresh amniotic membrane (group A), acellular amniotic membrane (group B), and no treatment in control group (group C), respectively. Histological observation and biomechanical analysis of the third toes were performed after repair. RESULTS AND CONCLUSION: (1) Histological observation. Congestive edema and inflammatory response were found in all animals at 2 weeks after repair, but mildest in the group A and severest in the group C. These inflammatory responses gradually alleviated over time in the three groups. At 12 weeks after repair, the new tendon sheath formed in all the animals, which was more mature than that at 4 weeks after repair. The synovial cells on the surface of the tendon sheath were arrayed tidily with dense structure in the groups A and B, but in the group C, the synovial cells were distributed disorderly with loose structure and prominent fibrous tissues. (2) Biomechanical analysis. Tendon sliding distance in the groups A and B was significantly larger than that in the group C at 4, 8, 12 weeks after repair (P < 0.05), but there were no significant difference in the distance between the groups A and B (P > 0.05). At 4 and 8 weeks after repair, the maximum tensile strength was largest in the group A, sequentially followed by group B and group C (P < 0.05), but there were no significant difference among the three groups at 12 weeks after repair (P > 0.05). To conclude, both fresh amniotic membrane and acellular amniotic membrane can promote tendon healing and prevent the adhesion of tendon through tendon sheath reconstruction, but the fresh amniotic membrane is preferred to promote early tendon healing compared with acellular amniotic membrane.

The mean (SD) age of the 14 patients with confirmed 2009 influenza A (H1N1) was (4.91 ± 4.14) years, 7 were female (50.0%). The median duration from symptom onset to hospital admission was (3.09 ± 1.30) days and from hospitalization to ICU admission was (0.95 ± 0.96) day. All the patients were severely hypoxemic [mean (SD) ratio of PaO2/FiO2 was (191.27 ± 80.58) mm Hg] at ICU admission. ARDS occurred in 11 cases (78.6%). Mechanical ventilation was applied for 10 patients (71.4%). The median duration of ventilation was (12.51 ± 10.03) days and ICU stay was (12.58 ± 10.65) days. The median length of time during which the real-time RT-PCR test results were positive was (17.27 ± 5.57) days; Comorbidities such as iron deficiency anemia, cerebral palsy and congenital heart disease were found in 8 cases (57.1%). The longer length of mechanical ventilation and ICU stay were found in cases with higher admission PRISM III Score and lower Pediatrics Critical Illness Score.</p><p><b>CONCLUSION</b>Critical illness due to 2009 influenza A (H1N1) in Suzhou occurred rapidly after hospital admission and was associated with severe hypoxemia, ARDS, a condition that required prolonged mechanical ventilation.
