Objective To evaluate the protective effect of inhaled nitric oxide(NO) on newborn piglets with asphyxia-induced myocardial impairment. Methods Twenty-nine newborn piglets were divided into three groups: (1)control group(CON,n =8); (2)asphyxia without NO inhaled group(ASP,n =11); (3)asphyxia with NO inhaled group (INO,n =10). In both ASP and INO group,asphyxia was induced by clamping the inhalation tube for 10min. After cardiopulmonary resuscitation (CPR),both groups were mechanically ventilated with 35% of O 2 for 6 hrs,but 10ppm of nitric oxide was applied additionally to INO group. Mean pulmonary artery pressure (mPAP) was monitored continuously. Serum creatine kinase,MB (CK-MB),and cardiac troponin T (cTnT) were measured at 6h after CPR. Cardiac functions were evaluated at 6h after CPR by echocardiography including left ventricular ejection fraction (LVEF),right ventricular ejection fraction (RVEF),ratio of peak E velocity and peak A velocity of mitrial flow and tricuspid flow (ME/A and TE/A),ratio of peak e velocity and velocity of mitral annulus motion and tricuspid annulus motion (Me/a and Te/a). The CON group was examined correspondingly. The myocardial histopathologic damage score (MHDS) was used to evaluate the severity of myocardial impairment. Results During 1 h to 6 h after CPR,INO group displayed a lower level of mPAP (14?6)～(12?4) mm Hg when compared with ASP group(23?5)～(19?3) mm Hg ( P

Objective To investigate correlations between nursing students’discrimination on psychopaths and exposure to them.Method One hundred and twenty-one nursing students were involved in the investigation by a general information questionnaire,a discrimination against mental patients scale(DAMPS)and an exposure to mental patients scale(FLS).Results The total mean score on discrimination,scores on isolation dimension and scores on capability were all significantly lower than the norms(all P<0.01).Negative correlation was observed between nursing students’discrimination against patients and exposure to patients(r=-0.31,P<0.05). Conclusion Measures should be taken to encourage nurses to understand patients so as to alleviate their discrimination.

We explored the status of Bartonella infection in rodents and the sequence characteristics of Bartonella in Fujian Province.Rodents in Fujian Province were captured by the night trapping method during 2014-2016.Information of the captured rodents on capturing dates and geographic locations,species,gender and ages were recorded.Heart blood samples were collected,from which the fragments of ghA gene and16S-23S rRNA gene of Bartonella were amplified by polymerase chain reaction (PCR).The PCR products were sequenced and the phylogenetic tree was constructed for homology analysis by biological analysis software.Data on infection rate were analyzed with Chi-square or Fisher exact test to indicate statistical significance.Results showed that 5 917 cages were laid and 381 rodents were captured,density of rodent was 6.44％.The overall Bartonella infection rate in rodents was 12.34 ％,while infection rate in domesticated rodents was 10.61％,with 11.30 ％ in Rattus norvebicus and 10.00％ in R.flavipectus.And the infection rate in wide rodents was 13.86％,with a rate of 22.86％ in Rattus losea and 18.00％ in R.fulvescens,respectively.The infection rate was higher in wild rodents than in domesticated rodents,however,no significant difference was found.The Western Fujian and Northern Fujian region had the higher infection rates of 20.00％ and 25.33％,and no infection was found in Southern Fujian region.The statistical analysis result revealed that a significant difference in infection rate among different region and habitats,but no significant difference in infection rate between male and female rodents,or among different ages.The BLAST results revealed the species to be B.tribocorum,B.elizabethae and B.grahamii.In conclusion,Bartonella infection is found in the rodents in Fujian Province and more attention should be paid on its impact on public health in the province.

Objective To investigate the effect of Roy Adaptation Model(RAM)in patients with adolescent insanity.Methods One hundred patients with adolescent insanity during October 2011 to March 2012 were randomized in equal number into two groups by random digit table:the study group and the control group.The former were intervened with RAM and the latter received routine care and health education.Seven weeks after intervention,Hamilton Depression Rating Scale(HAMD),Hamilton Anxiety Scale(HAMA) and Observation Scale(NOSIE)were used for the assessment. Results After intervention,the scores on HAMD and HAMA in the study group were significantly lower,compared to the control group(P<0.01).The scores on social function,social interest,subjective support and use of social support were all significantly higher than those of the control group(all P<0.01). Conclusions RAM can improve their ability of the patients with adolescent insanity to adapt to the environment.It may improve their mental state and their quality of life.

Objective To screen for genomic copy number variants(CNVs)in six neonates with Pierre Robin sequence(PRS)by Affymetrix 2.7 M chip to identify possible loci related to PRS.Methods Six neonates with PRS admitted into the Department of Neonatology,Children's Hospital of Fudan University from June 2009 to May 2010 were enrolled in this study.CNVs were detected by Cytogenetic Whole Genome 2.7 M array.Rare CNVs with potential clinical significance that deletion segments' size ＞50 kb and duplication segments' size ＞200 kb were selected based on the analysis of Chromosome Analysis Suite(ChAS)software,false positive CNVs and segments of normal population were excluded.The identified CNVs were compared with those in relative published literatures.Results(1)Among 6 PRS patients,two patients had facial deformation,two had congenital heart defects,one had congenital dysplasia of the laryngeal cartilage and one had choroidal space occupying lesion.(2)Seven rare CNVs whose size from 51-11 956 kb were identified in four neonates,including a 739 kb duplication on lp26.23-p36.22,a 6273 kb deletion on lq43-44,a 51 kb and a 55 kb deletions on 14q32.31,a 1022 kb duplication on 14q11.1-11.2,a 11 956 kb duplication on 20p13 and a 105 kb deletion on 4q23.3.(3)Published literatures showed that deletions of 1q43-44 and 14q32.31 might relate to micro/retrognathia and abnormal palate.Region of chromosome 1q43-q44 contained AKT3 and heterogeneous nuclear ribonucleoprotein U(hnRNPU)genes,and the haploinsufficiency of AKT3 and hnRNPU genes might cause developmental human microcephaly and agenesis of the corpus callosum,speech delay and seizures respectively.Region of chromosome 14q32.31 contained some C/D small nucleolar RNA,and the human imprinted 14q32 domain shared common genomic features with the imprinted 15q11-q13 loci.Conclusions This study established a method to discover whole genome CNVs in identifying novel submicroscopic deletions and duplications.Reviewing of published literatures suggested that deletions of chromosome 1q43-q44 and 14q32.31 might cause Pierre Robin sequence.

Objective To study the dynamic CT features of severe acute respiratory syndrome (SARS) in recovery phase, and to analyze the correlative remaining factors on CT images. Methods Total 50 patients with SARS were followed-up with chest spiral CT and HRCT in 3, 6, 9, 14, 24 months after onset. Results (1)The pulmonary lesions were completely absorbed in 24 cases in 3 months, 30 cases in 6 months and 37 cases in 24 months. Abnormal CT findings were showed in 13 patients later, which appeared ground-glass opacity 8,irregular lines 6, thickening of interlobular septa 4, subpleural lines 2 and bronchiectasis 2. (2)Reviewing the lesions on CT between the remained group in the third month and the absorption group, there was a difference in the extent and the progress of the lesions .(3) There was a difference of the appearance rate of remaining lesion in lungs in two groups (≥40 ages and

0.05).The differences were significant between the incidence of APCAs and the degree of pulmonary stenosis(P

The changes of intracoronary electrocardiogram (IC-ECG) and surface electro-cardiogram (S-ECG) were recorded simultaneously during percutaneous transluminal coronary angioplasty(PTCA) in 33 cases of coronary heart diseases with 41 vessel lesions. The results sug-gested that ST-segment change rate on IC-ECG(90. 2%) was higher than that on S-ECG(56%). ST-segment elevation on IC-ECG was earlier and more significant than that on S-ECG. The IC-ECG appeared to be more sensitive than S-ECG for detecting myocardial ischemia. The technique for recording IC-ECG is simple and it can help to perfome the PTCA successfully.

Objective: To investigate the prevalence of scoliosis among primary and middle school students in Jiaxing City, Zhejiang Province, so as to provide insights into scoliosis control among children and adolescents. Methods: Grade 4 to 6 primary school students and grade 1 to 3 junior high school students were recruited using a stratified cluster sampling method in Jiaxing City in 2019. Participants' demographic characteristics, dietary habits and nutritional status, physical activity, learning environments, reading and writing habits were collected using questionnaires. Scoliosis was screened through general examinations, forward bend test and scoliometer, and scoliosis was diagnosed with whole-spine X-ray scans in an erect position. The prevalence of scoliosis was descriptively analyzed among primary and middle school students. Results: A total of 8 026 primary and middle school students were included, 7 304 valid questionnaires were recovered, with an effective recovery rate of 91.00%. The respondents included 3 667 primary school students (50.21%) and 3 637 junior high school students (49.79%), and included 3 776 boys (51.70%) and 3 528 girls (48.30%). There were 659 participants with initial screening positive for scoliosis (9.02%), and the percentages of positive initial screening of thoracic, thoracolumbar and lumbar scoliosis were 2.93%, 4.56% and 4.56%, respectively. A higher percentage of positive initial screening of scoliosis was diagnosed among participants living in Pinghu City (10.45%), junior high school students (11.74%), girls (11.96%), students with a medical history of anemia (22.44%), students with less than 3 days of moderate-intensity physical activity in the past week (9.46%), students with less than 3 days of walking duration of over 10 minutes in the past week (10.18%), students with daily sitting duration of 5 hours and more in the past week (10.74%), students with their class seats exchanged every semester or month (10.28%), students with daily reading and writing duration of 3 hours and more after school (10.93%) and students with less than 10 cm distance from the chest at reading or writing to the edge of the table (9.67%) (all P<0.05). A total of 218 students received whole-spine X-ray scans in an erect position, 132 participants were definitively diagnosed as scoliosis (60.55%), and the estimated prevalence of scoliosis was 5.46%. Conclusion The percentage of positive initial screening of scoliosis was 9.02% among primary and middle school students in Jiaxing City. Gender, stage of learning, nutritional status, exercise frequency and habits of reading and writing may be factors affecting the development of scoliosis.

Objective To investigate the accuracy of 320-slice row CT system for the detection of coronary artery disease(CAD)in high pre-test probability population without heart rate/rhythm control.Methods Thirty patients with a high pre-test probability of CAD underwent 320-slice row CT without preceding heart rate/rhythm control.Invasive coronary angigraphy(ICA)served as the standard reference.Data sets were evaluated by 2 observers in consensus with respect to stenoses≥50% decreased diameter.The sensitivity,specificity,positive predictive value(PPV),negative predictive value(NPV)and Youden index were analyzed;the impact of heart rate and calcification on image quality as well as diagnostic accuracy were also analyzed by Chi-square test Results Mean heart rate during scanning was 73.7±15.4 beats per min(bpm),and median(QR)of Agatston score of segment was 45.6(181).On a per-segment analysis,overall sensitivity was 96.1%(74/77,95%CI:89.03%-99.19%),specificity was 98.3% (337/343,95%CI:96.23%-99.36%),PPV was 92.5% (74/80,95%CI:84.39%-97.20%),NPV of 99.1% (337/340,95%CI:97.44%-99.82%)and the Youden index was 0.94.In both heart-rate subgroups(242 in heart rate＜70 bpm group,169 in heart ratet≥70 bpm group),diagnostic accuracy for the assessment of coronary artery stenosis was similar(P＜0.05).The accuracy and the quality score of the subgroup Agatston score≥100 were lower than that of the subgroup Agatston score＜100;however,the difiercnce of results between 320-slice row CT and ICA was not significant(P＜0.05).Conclusion 320-detector row CT can reliably detect coronary artery stenoses in a high pre-test probability population without heart rate/rhythm control.
