RESUMO
Objective@#To understand current situation and associated factors of brucellosis infection among students in Mongolian middle school in Abaga Banner, and to provide basis for further development of prevention and treatment strategies.@*Methods@#Serological examinations were performed on pupils and middle school students in a Mongolian middle school in Abaga Banner. Questionnaire surveys were used to investigate students knowledge of eating behaviors related to brucellosis infection.@*Results@#A total of 500 primary and middle school students were investigated, and 6 cases of brucellosis were confirmed, and the infection rate was 1.20%. There were 4 cases of male infection and 2 cases of female infection. The infection rate in boys (1.61%) was higher than that of girls (0.79%). Higher proportion was found in 14-year-old group (n=3), accounting for 17.40%. The residence period of 10-15 years includes 6 cases of all infected persons. The number of infections in Narenbaolige Town was 4, accounting for 23.40%. Univariate logistic regression analysis shows that frequent consumption of unsterilized dairy products, milking, processing lambs or slugs and infected cloth The disease was positively correlated (OR=11.80, 139.14, 8.02, P<0.05). Multivariate Logistic regression analysis showed that milking was positively correlated with brucellosis infection(OR=20.19, 95%CI=2.01-202.74, P=0.01).@*Conclusion@#The brucellosis infection of Mongolian primary and middle school students in Abaga Banner is related to a variety of related dietary factors, and its prevention and treatment should be strengthened.
RESUMO
Objective To explore the relationship between syncope and risk of death in patients with cardiovascular emergencies including acute myocardial infarction(AMI), arrhythmia, acute heart failure(AHF), pulmonary thromboembolism(PTE) and aortic dissection(AD) rupture. Methods Data from 2 789 patients with cardiovascular emergency admitted from June 2010 to June 2016 in the Emergency Department, Air Force General Hospital, PLA was retrospectively analyzed. Difference in gender, age and motality were compared between patients with syncope and those without syncope. Among fi ve kinds of cardiovascular emergency events with syncope, difference in mortality were compared. Difference in mortality were also analyzed by the CHM corrected chi square test when difference of disease, gender and age were taken into consideration. Syncope, the type of cardiovascular emergency, gender and age were analyzed as potential risk/protective factors for death by the multiple logistic regression analysis. Results The mortalities of the fi ve diseases accompanied with syncope were 50%, 30.43%, 26.53%, 20% and 7.04% respectively in arterial dissection, pulmonary embolism, acute myocardial infarction, acute heart failure and arrhythmia.There was a statistically signifi cant difference in mortality among the fi ve kinds of cardiovascular emergencies accompanied with syncope(P<0.05).The mortalities of patients with syncope were significantly higher than those without syncopein AMI patients(26.53% vs.11.20%,P<0.05) and cardiac arrhythmias patients(7.04% vs.0.36%,P<0.05).The results of the CHM corrected chi square test showed that there was signifi cant difference in mortality between the syncope group and non-syncope group, when the differences in disease type, age and gender were adjusted (χ2=35.876, P<0.01). The mortality of syncope group was higher than that of non-syncope group.When age, gender and disease type were considered as covariates, the multiple logistic regression analysis showed that syncope signifi cantly increased the risk of mortality(OR=3.876,95% CI:2.362-6.359,P<0.01).Conclusion Syncope is an independent risk factor of death in patients with cardiovascular emergencies.
RESUMO
Objective To investigate the early diagnosis of sudden cardiac death so as to increase the resuscitating success rate.Methods 24 cases with sudden cardiac death were analyzed.Results In 24 cases,there were 10 cases resuscitated successfully,8 cases with heartbeats recovered died in 1～3 days,5 of which had average blood glucose of 21.6 mmol/L and blood sodium of 156 mmol/L,and 6 cases resuscitated unsuccessfully.Conclusion 70.83% was caused by AMI in 24 cases.The early diagnosis of AMI is mainly based on clinical manifestation.Althogh early ECG did not show it,AMI should not be denied and misdiagnosed.Resuscitation should be performed on the spot as soon as cardiac arrest occurs.Naloxone and NaHCO3 should be used rationally.Meanwhile,be sure to prevent and treat reperfusion-injury.The prognosis would be extremely poor if the patient showed hyperglycemia and hypernatremia during resuscitation.
