ABSTRACT

Objective To compare the predictive effect of Charlison's weighted index of comorbidities (WIC), the diagnostic criteria for emergency sepsis (MEDS) and combination of the two scoring systems to predict the emergency pulmonary infection prognosis. Methods A total of 327 patients with pulmonary infection admitted from January 2016 to January 2017 were enrolled in this study whose WIC score,MEDS score and risk stratification were recorded at admission.They were divided into survival group and death group according to the 28 d treatment outcome,the optimal cutoff of WIC score and MEDS score to predict the prognosis were found by ROC curve, and the prediction effect of WIC score, MEDS score, the combined use of both and APACHEⅡto predict the prognosis were compared. Results The mortality of low,middle and high risk of WIC score were 13.7%(29/212),48.7%(38/78)and 78.4%(29/37)with significant difference(χ2=82.097,P=0.000),mortality of low,middle and high risk of MEDS score were 11.3%(23/203),50.6%(40/77)and 73.3%(33/45)with significant difference(χ2=145.526,P=0.000).The WIC scores in survival group and death group were 1.3 ± 0.9 and 2.7 ± 1.1 with significant difference(t=11.030,P=0.000).The MEDS score of live group(6.1 ± 4.0) was significantly lower than death group(12.6 ± 4.9)(t=11.502,P=0.000).the optimal cutoff values of WIC and MEDS to predict prognosis were 1.7 points, 11.6 points, the ROC curve area between WIC, MEDS score and combined application to predict prognosis were 0.632, 0.798, 0.897, and the sensitivity and accuracy of the combined prediction[93.8%(212/226)/89.9%(294/327)] were significantly higher than those of the individual WIC[72.7%(168/231)/75.2%(246/327)] and MEDS[67.5%(156/232)/72.2%(236/327)] (χ2=0.562-42.594, P < 0.05). The sensitivity and accuracy of the combined application and APACHE Ⅱto predict of prognosis had no statistical significant difference(P>0.05).Conclusions The sensitivity and accuracy of WIC score combined with MEDS score to predict the prognosis of patients with acute lung infection is higher than the individual WIC score and MEDS score,and its prediction effect is more better.

ABSTRACT

Objective To explore the changes of cognition and sleep status in the youngsters with internet addiction disorder (IAD), and to clarify the relation between cognition and sleep-related indicators of IAD youngsters.Methods Event related potential (ERP) and Pittsburgh Sleep Quality Index (PSQI)test were used for forty-two IAD (case group)and forty non-IAD (control group) in youngsters, and the indexes of period latency (PL)of N1 ,P2 ,N2 ,P3 and amplitude of P3 (P3 amp)of ERP were analyzed,the factor scores of sleep quality (SQ), sleep latency (SL), sleep time (ST), sleep efficiency (SE), sleep dysfunction (SD), sleeping pills (SP), daytime dysfunction (DD)and total score of PSQI were analyzed. The correlation between the P3 PL, P3 amp of ERP and all the indexes of PSQI in case group was analyzed.Results The PL of N2 ,P3 of ERP in case group was significanly longer and the P3 amp was significantly lower than those in control group (P<0.01);the factor scores of the SQ,SL,ST,SE,SD,DD,and the total score of PSQI test had significant differences between two groups (P<0.01).The correlation analysis results showed that there were remarkable positive correlations between the P3 PL and the factor seores of the SQ,SL,ST,SE,SD,DD and the total score of PSQI test in case group (r=0.46,0.34,0.51,0.40,0.48,and 0.54;P<0.01),and there were remarkable negative correlations betweeb P3 amp and the indexes of PSQI test in case group (r=-0.42,-0.45,-0.49,-0.38,-0.38,and -0.50;P<0.01).Conclusion The IAD youngsters have cognition and sleep dysfunction,and the both factors can affect each other.

ABSTRACT

Objective To explore the relation between personality characteristics and event related potential P300 with internet addiction disorder(IAD) of youngsters.Methods Eysenck Personality Questionnaire and event related potential test were used for forty-two IAD and forty non-IAD in youngsters,and the results were compared between the two groups.Results The latency of N2,P3 ((267.2±24.2) ms,(374.5 ±22.0) ms) of event related potential in IAD group were significantly longer and the amplitude of P3 ((3.9± 2.5) μV) was significantly lower than those in non-IAD group((235.7±21.8) ms,(332.3±23.5) ms,(7.8±2.4) μV) (P<0.01).And the indexes of P,N score (56.2±9.4,49.8±7.4) of Eysenck Personality Questionnaire were significant higher than those in non-IAD group(51.9±9.7,42.4±7.5)(P<0.01),but the indexes of E,L score (45.7±9.0,44.3±7.9)of Eysenck Personality Questionnaire were significant lower than those in non-IAD group(51.2±9.4,50.9±8.3) (P<0.01).Correlation analysis showed that there were remarkable positive correlation with latency of P300 and P,N score of Eysenck Personality Questionnaire respectively in IAD group(r=0.49,0.54,P<0.01),and a significant negative correlation with E,L score(r=-0.43,-0.46,P<0.01),there was a remarkable negative correlation with amplitude of P300 and P,N score of Eysenck Personality Questionnaire respectively in IAD group(r=-0.41,-0.50,P<0.01),and a significant positive correlation with E,L score(r=0.45,0.47,P<0.01).Conclusion IAD in youngsters has personality characteristics and cognitive dysfunction,and it has a relation with personality and event related potential P300.

ABSTRACT

ObjectiveTo analyze the gene expression of neuregulin1 (Nrg1)mRNA and protein in encephalic region and peripheral blood,and to explore the consistency of the expression in central and peripheral in schizophrenia model rat induced by dizocilpine maleate ( MK801 ).Methods30 adult male SD rats were randomly divided into 3 groups ( 10 cases per group):model group injected with MK801 (0.6 mg/kg and 100μl/20 g)on the right rear of ventrolateral compartment,control group 1 ( no treatment) and control group 2 injected with equal volume normal saline.Nrg1 mRNA was measured in peripheral blood and in prefrontal lobe by using semiquantitative RT-PCR in 3 groups,and Nrg1 protein was measured in encephalic region (prefrontal lobe,dentate band and hippocamp) by using immunohistochemistry.ResultsThere was significant difference of the amount of Nrg1 mRNA among 3 groups (for center:F=9.141,P =0.001 ;for peripheral blood F =8.389,P =0.001 ),and it was higher in model group ( center:2.08 ± 0.64; peripheral blood:1.43 ± 0.46) than that in two control groups ( control group1,center:1.17 ± 0.42,peripheral blood:0.78 ± 0.39 ; control group 2,center:1.31 ± 0.44,peripheral blood:0.79 ± 0.37 ),but no statistical significant difference existed between two control groups.There was positive correlation of Nrg1 mRNA between center and periphery.There was significant difference of Nrg1 protein in prefrontal lobe,dentate band and hippocamp among 3 groups ( F value was 7.275,21.50 and 4.619,and P value was 0.003,0.000 and 0.019,respectively),and it was higher in model( 7.71 ± 2.55,11.67 ± 1.83and 10.18 ±2.08,respectively)than that in two control groups( control group 1:4.89 ± 1.06,7.53 ± 1.14 and 7.10 ± 2.52,respectively; control group 2:5.31 ± 1.39,8.10 ± 1.60 and 7.81 ± 2.50),but no statistical significant difference existed between two control groups.ConclusionMK801 can effect on the expression of Nrg1 gene,Nrg1 mRNA and protein increase in MK801 model rat,and the change is synchronous between center and periphery.
