Objective To investigate the dynamic change of procalcitonin (PCT ) and hypersensitive C‐reactive protein (hs‐CRP) in neonatal infection and its clinical significance .Methods 176 neonates with infection in our hospital from August 2013 to July 2014 were selected and treated by the routine therapy of anti‐infection ,oxygen inhalation ,etc .,and divided into the improvement group(89 cases) ,non‐change group(48 cases) and deterioration group(39 cases) according to the curative effect after 20 d therapy . Serum PCT and hs‐CRP levels were detected before treatment(T0) ,on 5 d(T1) ,10 d(T2) ,15 d(T3) and 20 d(T4) of treatment by adopting the enzyme linked immunosorbent assay(ELISA) .Results The PCT ,hs‐CRP levels and WBC count before treatment had no significant difference among 3 groups(P>0 .05);the PCT and hs‐CRP levels after treatment in the improvement group showed the significantly declining trend ,which reached the lowest at T4 (P<0 .05) ,while the PCT and hs‐CRP levels in the deterioration group showed the obviously rising trend ,which reached the highest at T4 (P<0 .05) ,but which in the non‐change group had no significant change (P>0 .05) .In terms of WBC count ,the WBC count in all the cases showed a rising first and then decreasing trend ,the WBC count at T4 in the improvement group was lower than before treatment(P<0 .05) ,while which in the deterioration group was higher than before treatment (P<0 .05) ,but which in the non‐change group had no significant change between before and after treatment(P>0 .05);the Spearman analysis results after treatment showed that the serum PCT ,hs‐CRP levels and WBC count were negatively correlated with efficacy (r1 = -0 .764 ,P1 <0 .05;r2 = -0 .724 ,P2 <0 .05 ;r3 = -0 .573 ,P3 <0 .05) .Conclu‐sion PCT and hs‐CRP can effectively reflect the therapeutic effect of neonatal infection ,and is closely correlated with the patient′s own immune status ,which can be taken as one of reference indicators for formulating the treatment scheme and evaluating progno‐sis ,and is worth for further clinical promotion .

Objective:To discuss the clinical significance of procalcitonin(PCT) and hypersensitive c-reactive protein(hs-CRP) test in early newborn infection. Methods:Sixty cases of our hospital treatment confirmed infection early newborn children were selected from June 2007 to July 2007,according to the condition was divided into severe infection group and local infection group, at the same time, 30 cases of our new pediatric infection in early neonatal were chosen as control group, to collect the moderate amount of peripheral blood of three groups before and after the treatment, detected and analyzed the levels of PCT and hs-CRP in the serum, Used Pearson correlation analysis to analysis the correlation of PCT and hs-CRP in the serum. Results: Severe infection group serum PCT, hs CRP levels and positive rate higher than that of local infection group, local infection group of PCT, hs CRP levels and positive rate is higher than the control group, the difference was statistically significant; Infection group before treated with serum PCT and hs-CRP levels and positive rate were higher than after treated(x2=7.248, x2=6.934; P<0.05); Pearson correlation analysis show that, according to the results of PCT and hs-CRP were positively correlated (r=0.533, P<0.533). Conclusion:Procalcitonin and hypersensitive c-reactive protein plays an important role in the infections of early neonatal children, PCT and hs-CRP were positively correlated, it can be used as an important index of early diagnosis of early neonatal infectious diseases.
