RESUMO
Objective To investigate the clinical significance of detecting cardiac troponin Ⅰ (cTnⅠ) and CK -MB in children with hand-foot-and-mouth disease and myocardial injury.Methods 90 children with hand-foot-and-mouth disease (observation group) were detected the level of serum cTnⅠ and CK-MB.At the same time,40 healthy children were chosen as control group.Results Compared with the control group,the levels of CK-MB and cTnl in observation group were significantly higher than those of the control group (t =8.92,5.46,all P ＜ 0.01),which indicated that children with hand,foot and mouth disease was easier to merge myocardial injury.CK-MB and cTnl levels in high-risk group were significantly higher than those in normal children group (t =9.17,6.13,all P ＜ 0.01),and the levels of CK-MB and cTnl were positively correlated with severe degree (r =0.767,0.683,all P ＜ 0.01).For children with hand,foot and mouth disease merged myocarditis,cTnl diagnostic sensitivity (53.8％) was lower than that of CK-MB diagnostic sensitivity (71.8％),but the specificity was better than that of CK-MB,and the diagnosis of cTnl detection window 2 weeks longer than CK-MB,but after 2 weeks both lose their clinical diagnostic significance.Conclusion Children with hand,foot and mouth disease easily merge myocardial damage,dynamic measuring CK-MB and cTnl levels could help early diagnosis of children with hand,foot and mouth disease whether merged myocardial damage,both applications can also complement each other,more timely and accurate reflection of disease progression and recovery,it is worth promoting.
RESUMO
Objective To investigate the predictive value of umbilical cord blood bilirubin for pathological jaundice in healthy term newborns. Methods Two ml navel string vein blood of baby were collected after giving birth in the normal newborn, and the hemobilirubin was detected by accidentally oxidation method. After birth, the infant's bilirubin level was tested on the forehead by the transcutaneous bilirubinometer at 8:00 -9:00 every morning until discharging from hospital. The ration of pathological jaundice of newborn and its treatment were analyzed in different levels of cord blood hemobilirubin. Results Fifty-nine cases ( 22.96% ) with pathological jaundice were diagnosed in 257 newboms.The concentration of cord blood hemobilirubin in baby with pathological jaundice [(39.68 ±8.10) μmol/L] was significantly higher than that of the normal newborn [(30.05 ±5.51) μmol/L](P＜0.01). As the concentration of cord blood hemobilirubin was increased, the incidence of pathological jaundice was raised (P＜ 0.01), and the cases that needed to intervention treatment was increased(P＜ 0.01). Conclusion The detection of the level of cord blood hemobilirubin is not only very worthy to estimate the occurrence of pathological jaundice of newborn, but also offer reliable evidence for clinical early diagnosis and treatment.
