RESUMEN
Objective To analyze the correlation between the fractional exhaled nitric oxide (FeNO) levels and blood eosinophil (EOS) count and the frequency of wheeze in infants with recurrent wheezing.Methods From February 2015 to August 2016 in the General Hospital of Northern War Zone,outpatient department of Pediatrics treatment and hospitalization of age less than or equal to 3 year old children with recurrent wheezing,101 cases were induded as the research object.On the basis of asthma predictive index (API) score were divided into API positive group (n =55) and API negative group (n =46),according to the wheeze frequency of the two groups children were divided into 3 ～ 4 times wheezing groups and more than 5 times.Select 37 cases of healthy children as control group.The concentration of FeNO and blood EOS count are detected in all the children.The correlation between the three groups of children with FeNO concentration,the correlation between FeNO and blood EOS count,the correlation between the the frequency of wheeze and FeNO in experimental groups were analyzed.Results (1) API positive group mean FeNO (19.3 ± 6.2) ppb was significantly higher than API negative group (7.7 ± 2.9) ppb,there was no difference (P ＞ 0.05).API negative group mean FeNO (7.7 ± 2.9) ppb is lower than the normal control group (9.5 ± 2.0) ppb,there was no difference (P ＞0.05).(2) API positive group mean EOS count (124.7 ± 1.6) x 106/L is higher than API negative group (86.1 ± 1.9) x 106/L,there was significant difference (P ＜ 0.01);(3) There was a correlation between FeNO level and blood EOS count in API positive group,there was no correlation between FeNO level and blood EOS count in API negative group and con~ol group.(4) No statistical differences were found in ≤4 times wheezing groups and more than 5 times of the mean FeNO.Conclusion There is no significant difference in the mean value of FeNO between different times of wheezing in children with recurrent wheezing.The combination of medical history,EOS,FeNO and API might be used to predict the wheezing episode of infants.
RESUMEN
Objective To study the incidence of acute renal injury ( AKI), related clinical risk factors and recent prognosis in critically ill neonates. Methods The study was a retrospective analysis from January 2016 to December 2016 in the neonatal care department of General Hospital of Shenyang Military Region and the First Hospital Affiliated to China Medical University. We collected the perinatal data,clinical data,biochemical indexes and short-term prognosis. Logistic regression analysis was used to identify the risk factors. Results The incidence of AKI in critically ill neonates was 13. 11%(32/244),and the probability of poor prognosis was 62. 50%(20/32). Gestational age,birth weight,1 min and 5 min Apgar score,con-sciousness,mechanical ventilation,blood pH,blood glucose,blood urea nitrogen,white blood cell and red cell distribution width were the related factors for AKI in critically ill neonates. Logistic regression analysis showed that consciousness(OR=4. 542,95%CI 1. 176-17. 539,P=0. 028),mechanical ventilation(OR=0.267,95%CI 0.101-0.705,P = 0.008),5 min Apgar score(OR = 0.750,95% CI 0.605-0.930,P =0. 009),blood urea nitrogen value(OR=1. 074,95%CI 1. 006-1. 146,P=0. 030)were identified as the inde-pendent risk factors of AKI. ConclusionThe incidence of AKI is high in critically ill neonates. Consciousness,mechanical ventilation,5 min Apgar score,blood urea nitrogen value are identified as independent risk factors for AKI.
