Objective To investigate the expression level of hyper sensitivity C-reactive protein (hsCRP) in children infected with different pathogens in order to enhance the application value of hsCRP .Methods One hundred and one children patients with infection from March 2010 to March 2015 were selected as the research subjects and divided into the bacterial infection group (67 ca-ses) and mycoplasma infection group (34 cases) according to the hematology and bacterial culture results .Contemporaneous 50 healthy children were selected as the control group .Venous blood was collected for detecting hsCRP ,white blood cell(WBC) and neutrophil percentage(NEUT% ) .Results The levels and abnormal rates of hsCRP and WBC in the bacterial infection group were significantly higher than the those in the mycoplasma infection group and control group (P<0 .05);NEUT% and abnormal rate in the mycoplasma infection group was higher than that in the other two groups (P<0 .05) .The levels and abnormal rates of hsCRP and WBC after treatment in the bacterial infection group were lower than those before treatment ,the difference was statistically sig-nificant(P<0 .05);the area under the ROC curve of hsCRP for diagnosing bacterial infection wa maximal ,which was 0 .68 ,the sensitivity and specificity were 89 .9% and 88 .3% respectively .Conclusion The hsCRP level detection has early diagnostic value for child bacterial infection and can dynamically reflects the curative effect .

Objective To evaluate the clinical value of bone alkaline phosphatase in early diagnosis and treatment effect of chil-dren′rickets and to understand the incidence rate of rickets in children in the local region by the detection of neonatal bone alkaline phosphatase(NBAP).Methods 2 184 children with physical examination in our hospital from January to December 2013 were se-lected and divided into the infants,young children,preschool and school-age children groups according to age.The finger blood was collected for detecting the bone alkaline phosphatase in the peripheral blood by the bone alkaline phosphatase reagent kit provided by Beijing Jinyu diagnosis technology Co.,Ltd.Results Among detected 2 184 children,the detection rate of clinical rickets(NBAP>250 U/L)was 10.1 %,moreover the smaller the age,the higher the detection rate;the detection rate of subclinical rickets(NBAP 200~250 U/L)was 65.5%,indicating that most children in Baoji region were in sub-health state;the detection rate in spring and winter was higher than that in summer and autumn;the detection rate of NBAP had no gender difference.Conclusion Children are in the rapid growth and development period,easy to suffer from vitamin D deficiency,the activity detection of NBAP has important clinical value in the early diagnosis of rickets caused by vitamin D deficiency.Prevention should begin from perinatal period and NBAP should be timely detected in order to conduct early diagnosis and early treatment.
