Objective:This research integrated the attribution of responsibility and aggressive retaliation to find their relationship. Methods: 204 subjects attended this experiment, and two structural equation models that reflect the relationship among intentional attribution, affect, responsibility and aggressive retaliation were set up. EQS was used to test the models. Results: The data fitted both Weiner's model and ours well, which suggested that intentional attribution contributed to the judgment of responsibility and the response of affects, and then linked with the retaliation action. And in this process, judgment of responsibility and the response of affects were two media variables that had two-way interrelationship. Conclusion:A general model suggested here was:intentional attribution →judgment of responsibility, affect response →aggressive retaliation.

Objective To study the relationship between TXA 2/PGI2 and pulmonary hypertension in Congenital Heart Disease(CHD).Methods The serum concentration of TXB2/6-K-PGF1? was determined in 63 patients with CHD by radioimmunoassay. Results TXB2 ，TXB2 /6-K-PGF1? increased significantly in P H,while 6-K-PGF1? decreased,the TXB2 /6-K-PGF1? varied in different PH groups(P＜0.05).Conclusion TXA2/PGI2 plays an important role in the pathogenesis of PH se- condary to CHD.

Objective To evaluate the endothelialization of Chinese nitinol atrial septal defect occlud-er device. Methods Atrial septal defect with controllable size was created by the Brockenborough needle and Rashkind balloon atrial septostomy, the occluder devices were implanted in six piglets (mean weight 7. 5 kg). Two pigs were killed each time after 1 month, 3 months and 6 months after the device implantation and then the explanted devices were examined by scanning electron microscope (SEM). Results The devices were found covering with collagen fibrosis together with diffuse endothelial cells spreading over the primer 1 month after implantation. The implants were covered mostly by ncointima 3 months after implantation and completely covered by confluent endothelial cells 6 months after the implantation. Endothelial cells were not found on the smooth marker band at 3 months, however, did exist by 6 months. Conclusions Home-made atriatseptal defect occluder devices were mostly endothelialised 3 months after the implantation and did completely at 6months.

OBJECTIVE To investigate the distribution and antimicrobial resistance among clinical isolates of Acinetobacter baumannii(ABA) from July 1 to Dect 31 2007 in Haidian Hospital of Beijing.METHODS A retrospective study on clinical distribution and antimicrobial resistance of 22 antibiotics to ABA was undertaken.RESULTS ABA frequently detected out in phlegm specimen with the detection rate of 86.4%.The drug-resistance to SCF and AMK was the lowest.CONCLUSIONS ABA had severe drug-resistance,SCF and AMK keep better activity to ABA.Rational selection and use of antibacterials is important to prevent the appearance of drug-resistance of ABA.

Objective To improve the understanding of Amiodarone in the treatment of intractable incessant tachycardia in children. MethodsData of 80 patients with intractable incessant tachycardia treated by Amiodarone were summarized. Among them 52 were male,38 were female,and average age was 2.5 years old. ResultsAmiodarone reduced heart rate effectively, with about 90% effective. Simultaneously, it could convert tachycardia into sinus rhythm and succeeded 67% in atrial tachycardia, 92% in paroxysmal supraventricular tachycardia,89% in junctional ectopic tachycardia, 56% in ventricular tachycardia respectively. Use of small dosage of β-receptor blocker together with Amiodarone showed synergy. Hypotension and bradycardia are the main side effects. ConclusionsToo rapid and sustained tachycardia can lead, to hemodynamic disorders and cause heart failure, it requires urgent and adequate treatment. Amiodarone can be used to treat different kinds of intractable incessant tachycardia, and is safe and effective in patients with relatively stable hemodynamis.

Objective To observe the effect of leukocytapheresis(LCAP)on the coagulation,fibrinolysis system and lung injury in the endotoxemia dog and explore the mechanism in the endotoxin-induced lung injury dog. Methods Endotoxemia-induced model in dogs was established by administration of lipopolysaccharide(LPS,2 mg/kg).Separation of the leucocytes wag performed with the automated continuous flow blood cell separators.A total of 30 male mongrel dogs were randomly divided into LPS group(group L,only injected with LPS,with no LCAP),sham LCAP group(group S,received sham LCAP at 12-14 hours after administration of LPS)and LCAP treatment group(group T,received LCAP at 12-14 hours after administration of LPS),10 dogs per group.The dynamic changes of the activated protein C(APC),soluble thrombomodulin and plagminogen activator inhibitor-1 in the serum were measured at 0 hour before LPS administration,at 2,6,12,14,16,24 and 36 hours after administration of LPS.Results Through LCAP,there found the following four results:(1) the APC level in the serum of the group T wag(50.805±4.422)μg/ml and(40.480±2.993)μg/ml at 14 hours and 16 hours respectively,which were significantly higher than(45.881±4.024)μml and(35.935±4.057)μg/ml in the group L(P<0.05).(2)The expressions of soluble thrombomadulin in the group T was (9.688±O.914)μml and(10.492±O.865)μg/ml at 14 hours and 16 hours respectively,which was statistically lower than(11.005±0.854)μg/ml and(12.04±0.954)ug/ml in the group L(P<0.05).(3)Thelevel of plagminogen activatorinhibitor-1 in the group T was lower than that in the group the group T Wag statistically lower than that in the group L(ALI/ARDS occurred in 2 and 7 dogs of the groups T and L respectively within 36 hours after infusion of LPS.P<0.05). Conclusions At the decrease the incidence of acute lung injury partly due to its role in improving the function of coagulation and fibrinolysis.

ObjectiveTo analyze the association of human urate transporter 1 ( hURAT1 ) gene promoter single-nucleotide polymorphisms(SNPs) with primary hyperuricemia ( HUA ) in Chinese Han people.MethodsA total of 215 patients with HUA and 323 healthy subjects were chosen to be investigated of SNP of hURAT1 promoter by PCR and sequencing.ResultsFive SNPs were identified,including-454A/T,-434T/C,-382C/T,-87C/T,and + 118G/A.Pairwise linkage disequilibrium analysis displayed a high linkage disequilibrium between the five SNPs ( r2 =0.99).In HUA group,the heterozygous genotypos ( AT,CT,CT,CT,AG ) frequencies were significantly lower than those in control group ( P＜0.05 ).Logistic regression analysis showed that the heterozygosis genotypes ( AT,CT,CT,CT,AG) were protective factors of HUA ( OR 0.68-0.75 ).The minor allele ( T,C,T,T,A ) frequencies for both SNPs were significantly different between two groups ( P =0.022,P =0.038 ).ConclusionThese findings indicate that -454A/T,-434T/C,-382C/T,-87C/T,and + 118G/A SNPs of hURAT1 gene promoter area are associated with HUA in Chinese Han population.

Objective To analyze the level of cardiac troponin I (cTnI) in children with left-to-right shunt congenital heart disease (CHD). Methods In this study, 146 children with secundum atrial septal (ASD) defect, 132 children with ventricular septal defect (VSD) and 300 healthy children were recruited. The levels of cTnI and N-terminal pro-brain natriuretic peptide (NT-proBNP) were measured and their correlation with clinical data was analyzed. Results The serum cTnI and NT-proBNP levels in both ASD and VSD patients were signiifcantly higher than those in normal children (H=3.89 and 5.27, P<0.01). The serum cTnI and NT-proBNP levels in VSD patients were signiifcantly higher than those in ASD patients (P<0.05). The ratio of pulmonary to systemic arterial pressure (Pp/Ps), pulmonary vascular resistance index (PVRI) and standardized left ventricular end diastolic volume in VSD patients were signiifcantly higher than those in ASD patients (P<0.05). Multiple regression analysis showed that Pp/Ps was signiifcantly correlated with cTnI in VSD patients. (β=0.81, SE=0.03, P=0.000). Conclusions Signiifcant volume and pressure overload due to a left-to-right shunt induce myocardial injury and could lead to irreversible myocardial remodeling in children with CHD. The serum cTnI level is a sensitive biomarker for myocardial damage in VSD patients.
