RESUMEN
Objective To observe the serum calcitonin original (PCT) detection in the diagnosis of children with infectious pneumonia.Methods From March 2014 to April 2015,96 children with infectious pneumonia were selected,including bacterial pneumonia in 43 cases,26 cases of viral pneumonia,27 cases of Mycoplasma pneumonia.50 healthy children were selected as control group.All children received serum calcitonin original test,PCT test was applied in the diagnosis of children with infectious pneumonia.Results The PCT level in children with bacterial pneumonia group was(3.84±3.57)μg/L,which was obviously higher than (0.12±0.03)μg/L of healthy children,(0.74±0.13)μg/L of children with viral pneumonia and (1.07±0.08)μg/L of pure chlamydia pneumonia patients(F=6.120,P=0.013).Before treatment,the level of serum PCT in children with bacterial pneumonia was significantly higher than that in normal children[(3.84±3.57)μg/L vs.(0.12±0.03)μg/L,t=6.987,P=0.000].After treatment,the results of PCT detection in serum of children with bacterial pneumonia was significantly lower[(3.84±3.57)μg/L vs.(0.16±0.03)μg/L,t=6.978,P=0.000)].Conclusion Serum calcitonin original detection can effectively help the differential diagnosis of pediatric infectious pneumonia,has clinical application value.
RESUMEN
Objective To study the change of serum diamine oxidase (DAO) level in patients with severely acute pancreatitis (SAP) in order to explore the role of DAO in assessing the severity of SAP and the magnitude of gastrointestinal dysfunction.Methods From January 2012 through December 2013,56 SAP patients with 33 male and 23 female and average age (45-± 14) years admitted within 3 days after onset were enrolled for this study.At admission,serum diamine oxidase (DAO) was detected,and APACHE Ⅱ score,computed tomography severity index (CTSI) score and Balthazar grading and gastrointestinal dysfunction score were calculated.And at the corresponding time,serum procalcitonin (PCT) was detected.The correlations between serum DAO level and 4 other markers were analyzed.Results The high level of serum DAO was found at admission in SAP patients correlating positively with serum PCT concentrations (r =0.516,P＜ 0.01),APACHE Ⅱ score (r =0.631,P＜ 0.01),CTIS score (r=0.640,P ＜ 0.01),and the degree of gastrointestinal dysfunction (r =0.730,P ＜ 0.01).Conclusions The role of serum DAO in assessing the severity of SAP and magnitude of gastrointestinal dysfunction in SAP patients is really valid.
