Objective To analyze the difference of laboratory test results between early-onset and late-onset severe preeclampsia and to investigate their clinical application values.Methods Totally 108 blood samples were collected from patients with severe preeclampsia who were diagnosed according to the Diagnostic Standard of Obstetrics and Gynecology(7th Edition) published by People′s Medical Publishing House,in Shandong Provincial Hospital affiliated to Shandong University from March to November 2016,which consisted of 64 early-onset severe preeclampsia before 34 weeks gestation(early onset group) and 44 late-onset severe preeclampsia after 34 weeks gestation(late onset group).In addition,42 women with normal pregnancies as the control group were selected.General clinical data were collected,and the blood sample was analyzed through detecting Hb,PLT,fibrinogen (FIB),D-dimer,AST,ALT,urea,creatinine (Cr),uric acid,CRP,urine protein.The tested results were analyzed and compared.Flow cytometry was used to analyze the proportion of T helper 1 cells(Th1) and T helper 2 cells(Th2),and the ratio of Th1/Th2 was also calculated.All data and F test were performed by use of statistical software SPSS19.0.Results The pre-pregnancy body mass index(29.55±4.49,30.66±5.13,26.62±3.17,F=9.829,P<0.05),diastolic blood pressure[(105.17±14.46)mmHg(1 mmHg=0.133 kPa),(99.80±12.56)mmHg,(74.36±8.42)mmHg,F=82.088,P<0.05],Hb[(123.22±14.38)g/L,(117.03±16.48)g/L,(112.62±11.24)g/L,F=7.133,P<0.05],urea[(6.56±2.36)mmol/L,(4.51±1.35)mmol/L,(3.04±0.87)mmol/L,F=51.733,P<0.05],Cr[(68.47±18.05)μmol/L,(61.37±14.37)μmol/L,(48.54±8.73)μmol/L,F=23.737,P<0.05],CRP[(7.68±8.76)mg/L,(5.88±6.03)mg/L,(3.56±2.41)mg/L,F=4.735,P<0.05],urine protein[(3.66±0.76)g/L,(2.20±1.05)g/L,(0.19±0.40)g/L,F=249.714,P<0.05]had a statistically significant difference among the early-onset,late-onset and control groups.The flow cytometry results demonstrated that the proportion of Th1 in early-onset group(19.83±3.04)was higher than that in both late-onset (14.49±2.79)and control groups(11.78±1.17),on the contrary,the result of Th2 was much lower(early-onset:1.02±0.12,late-onset: 1.11±0.12,control: 1.56±0.11),there was statistical significance among these three groups(Th1: F=135.110,P<0.05;Th2: F=293.687,P<0.05).Conclusions It′s necessary to real-time monitor the laboratory indicators,such as liver and kidney function,especially the immunologic function indicators for evaluating the disease of early-onset and late-onset severe preeclampsia and personal treatment,and for ensuring the health of mother and fetus and improving the prognostic of mother and fetus.

Objective To investigate the clinical significance of Epstein-Barr virus EBV DNA in children with Epstein-Barr virus infection realated diseases.Methods A retrospective cohort study was performed.Totally 222 blood samples were collected from children who were diagnosed as EBV infection in Shandong Provincial Hospital from June 2012 to August 2013.Fluorescent quantitative PCR( FQ-PCR) was used to analyze the EBV DNA in peripheral blood lymphocytes.ELISA was used to analyze the four EBV serology antibodies in the serum.Two groups of tested results were compared.Heart, hepatic impairment and renal function were analyzed through detecting AST, ALT, BUN, CREA, CK, CKMB.The results were grouped by EBV DNA copy number, and then non-parametric test together with correlation analysis was performed using SPSS21.0 analytics software.Results The positive rate of EBV-CA IgM and EBV DNA was 51.35%(114/222) and 72.97% (162/222) respectively, χ2 =24.01, P1 ×106 copies/ml,Ⅱ1 ×105 -1 ×106 copies/ml, Ⅲ1 ×104 -1 ×105 copies/ml, Ⅳ5 × 103 -1 ×104 copies/ml, Ⅴ<5 ×103 copies/ml), and ALT(χ2 =10.14,P<0.05), BUN(χ2 =18.17, P<0.05), CK(χ2 =13.09,P<0.05), CKMB(χ2 =17.93,P<0.01) had a statistically significant difference between each group.Well, the log value of EBV DNA copy number had a positive correlation relationship with AST(r=0.357,P=0.001), ALT(r=0.376,P=0.001), BUN(r=0.329,P=0.000), CK(r=0.235,P=0.035).Conclusions Detection of EBV DNA can be used for the early diagnosis and assessment of process of the EBV infection related disease in children.The detection of liver, kidney function and myocardial enzymes can be used for evaluating the severity of EBV infection.
