RESUMEN
Objective:To analyze the predictive value of four scoring systems,Pediatric Clinical Illness Score (PCIS),Pediatric Logistic Organ Dysfunction Score 2 (PELOD-2),Pediatric Risk of Mortality Ⅲ (PRISM Ⅲ),and Pediatric Sequential Organ Failure Assessment (pSOFA),in the severity and prognosis in pediatric sepsis.Methods:The medical records of 159 children with sepsis who admitted to PICU at the First Hospital of Jilin University between August 2015 and December 2020 were retrospectively analyzed.The PCIS,PELOD-2,PRISM Ⅲ and pSOFA scores were calculated according to the worst value of each index within 24 h of admission.The children were divided into survival group and death group based on clinical outcomes during hospitalization.The children were stratified according to the severity of sepsis into sepsis (no organ dysfunction) group ( n=18) and severe sepsis group ( n=141).The receiver operator characteristic (ROC) curve was used to evaluate the value of PCIS,PELOD-2,PRISM Ⅲ and pSOFA scores in predicting the severity and prognosis in pediatric sepsis. Results:There were 97 (61.01%) cases in the survival group and 62(38.99%) cases in the death group.There were 141(88.68%) children with severe sepsis.The areas under curve (AUCs) of PCIS,PELOD-2,PRISM Ⅲ and pSOFA scores for predicting severe sepsis in children with sepsis were 0.869,0.875,0.672 and 0.933,respectively (all P <0.05).The AUCs of PCIS,PELOD-2,PRISM Ⅲ and pSOFA scores for predicting the death of children with sepsis in PICU were 0.687,0.697,0.716 and 0.656,respectively (all P<0.05). Conclusion:Among the four scoring systems,the pSOFA scoring system had the highest predictive power for the severity of sepsis.The PRISM Ⅲ score had higher value in assessing the risk of death in all patients with sepsis.
RESUMEN
Objective To examine the influence of systemic rehabilitation exercise on social functioning in chronic schizophrenic patients.Methods 60 qualified cases selected from chronic psychiatric inpatient department were randomly divided into two groups according to admission number (AD).30 cases in treatment group accepted hospitalized systemic rehabilitation exercise and 30 controls accepted ordinary treatment for 6 months.Social functio-ning evaluated with SSPI and PSP.Results The total score of SSPI(t=1.322,P=0.256) and PSP(t=1.563,P=0.362) were not significantly higher(P>0.05),The total score of SSPI [(37.44 ±4.33)points,t=2.719,P=0.001]and PSP[(72.14 ±6.86)points,t=3.985,P=0.000]total score in the treatment group were significantly higher than that in the control group(P0.05).Conclusion Systemic rehabilitation training does influence on social functioning in chronic schizophrenic patients.
RESUMEN
Aim To isolate and purify a novel plasminogen activator(PA)from Gloydius brevicaudus venom(GBV)and study characterization and biological activities of GBV-PA.Methods Affinity chromatography in Benzamidine Sepharose 6B(AC)and Lichrospher C-18 4.6/250 reversed phase chromatography(RPC)were used for isolation and purification;SDS-PAGE was used to detect molecular weight(MW);Disc polyacrylamide gel eletrophoresis was used to measure the point of isoelectric(pI);Chromogenic substrate method was used to observe the biological activities.Results A novel GBV-PA which its purification reached the homogeneity level was isolated and purified from GBV by AC and RPC;The MW of the novel GBV-PA was 3.26?104 and the pI was 5.2;The novel GBV-PA activated human plasminogen specifically and the special activity was 2.87 t-PA IU?mg-1;Moreover,our results indicated that this novel GBV-PA was a serine proteinase which had no affinity to fibrin.Conclusion A novel GBV-PA that can be isolated and purificated from GBV by AC and RPC was proved to be a serine protease and has no affinity to fibrin.
