ABSTRACT

Objective To investigate the relationship between neonatal umbilical cord blood cytokine interferon-γ (IFN-γ),interleukin-4 (IL-4),interleukin-12 (IL-12),interleukin-18 (IL-18) and hepatitis B virus (HBV) intrauterine infection.Methods Seventy-five newborns delivered by HBsAg-positive pregnant women in the First Hospital of Hebei Medical University and the Fifth Hospital of Shijiazhuang from December 2017 to June 2018 were selected as observation group.According to the results of five items of hepatitis B and HBV DNA test in cord blood of newborns,17 of them were positive as intrauterine infection group,and 58 of them were negative as uninfection intrauterine group.Forty-three newborns delivered by healthy pregnant women with negative HBsAg were taken as control group.The levels of cytokines IFN-γ,IL-4,IL-12 and IL-18 in cord blood of neonates were detected by ELISA,Results The levels of IFN-γ,IL-4,IL-12 and IL-18 in the newborns of intrauterine infection group were (409.51 ±51.77),630.51(612.49,647.33),85.60(56.11,133.99),32.41 (23.04,87.53) ng/L.The levels in the uninfected intrauterine Group were (523.87 ± 38.45),573.33 (531.95,598.38),186.53 (77.77,302.66),125.99(63.32,202.73) ng/L.The levels in the control group were (509.39±73.02),565.83 (443.40,620.82),199.89 (128.92,289.30),152.98 (86.76,188.57) ng/L.There were significant differences in IFN-γ,IL-4,IL-12,IL-18 between the intrauterine infection group and the uninfected intrauterine group and the control group (all P<0.01).There was no significant difference between the uninfected group and the control group (all P>0.05).Conclusion The decrease of IFN-γ,IL-12,IL-18 and the increase of IL-4 in cord blood of neonates result in the decrease of viral clearance ability and the failure of HBV clearance,which leads to intrauterine infection of neonates with HBV.

ABSTRACT

Objective Acute bilirubin encephalopathy in neonates is the most serious complication of neonatal hyperbilirubinemia, is one of the main causes of neonatal death and disability. Clinical early diagnosis, early treatment can improve the prognosis in children. Methods Brainstem auditory evoked potential (BAEF) was detected on two patients (40 patients with ABE, 40 cases of normal controls, all full-term) in the state of sleep in children and analysis the difference between the two groups ,all testing was completed by experienced Department of ENT full-time technician in charge,SPSS15.0 statistical analysis software was took for data analysis (using rank sum test method). Results There was significant difference between the two groups of neonatal latency of wave I, latency of waveⅤ, interpeak time , acute bilirubinⅠ-Ⅴencephalopathy group was significantly longer than that of the control group. Conclusions The BAEF detection is the sensitive index of brainstem damage , can objectively and sensitively reflect the function of the central nervous system , can reflect the functional status of cochlear and brainstem structures , often brainstem was slightly damaged but no clinical symptoms and signs , BAEP has changed significantly , so the conventional BAEP examination performed on patients with hyperbilirubinemia help to find bilirubin brain damage as early as possible,and prevent the occurrence of bilirubin encephalopathy.

ABSTRACT

Objective To evaluate the diagnostic utilities of CD64,CDllb,sICAM-1 and sE-selectin in early identification of neonatal sepsis related to bacterial infection. Methods The group of sepsis consisted of 36 newboms and the control group included 26 healthy newboms. The blood samples were collected right after being admitted to hospital and at recovery stage in the group of sepsis,as for the control the blood samples were collected only once in the study. In the sepsis group,blood samples were also taken in bacterial culture before treatment CD64 and CDllb were quantified with direct immunofluorescence staining and the whole blood cell flow cytometry analysis. sICAM-1 and sE-selectin level were determined by ELJSA assay,along with CRP. Results The expression level of CD64 in neonates with sepsis was (60. 37 22. 70) .shown in MFI,which was significantly higher than that in the group of control (23. 14 ±5. 10) MFI(P <0. 01). The expression level of CDllb in neonates with sepsis was (1645. 14 ±463. 68) MFI,which was significantly higher than that in the group of control (1041.48 ±260. 34) MFI (P < 0. 01). The concentration of blood sICAM-1 in neonates with sepsis was (240. 20 ± 83.46) μg/L, which was significantly higher than that in the group of control (100. 24 ±51.03)μg/L(P <0. 01). The concentration of blood sE-selectin in neonates with sepsis was (29. 63 ±9. 88μg/L,which was significantly higher than that in the group of control (14. 12 ±5. 33)μg/L(P <0. 01). In the sepsis group,the level of CD64,CDllb,sICAM-l and sE-selectin in the primary stage was higher than the recovery stage significantly (P <0. 01). The sensitivity of above-mentioned molecular markers were 95. 7% , 82. 6% , 81. 8% and 87. 0% , respectively, and the specificity were 95. 8% , 79. 2% ,86.9% and 79.2% . CD64 was the best one. Conclusions CD64 may serve as one of the reliable biomarkers in the early diagnosis of neonatal sepsis, and it may play important role in the treatment of neonatal sepsis.
