Journal of Clinical Pediatrics 2015;(2):136-140
Objective To investigate the risk factors and predictors of poor outcome in full-term neonates with severe hyperbilirubinemia. Methods Data were retrospectively collected from 326 neonates with severe hyperbilirubinemia hospitalized between January 1, 2012 and December 31, 2012. Results A total of 326 full-term neonates with severe hyperbilirubinemia were included in this study (181 males and 145 females). The average gestational age was 39.12±1.17 weeks. Two hundred and sixty (260) cases were followed up successfully by phone while 66 cases were lost to follow-up. Infection (74.40%) and hemolytic disease (51.19%) were the main causes of severe hyperbilirubinemia. Multiple factors regression analysis found that threshold TSB was an independent risk factor of poor outcome (OR=2.02, 95%CI:1.13~3.62, P=0.018). The outcome of neonates with BIND scored between 0-6 had poor prognosis and some of them were reversible, and the outcome in those scored between 7-9 were of worse prognosis. Threshold TSB, USB and B/A ratio in group of poor outcome were signiifcantly higher than those in other groups and their area under the ROC curve evaluating the prognosis was 0.682, 0.671 and 0.698, respectively. With TSB at 474.5 μmol/L, UCB at 449.15 μmol/L and B/A at 0.923 mg/g, Youden index was the higest. The results of BAEP, OSE, MRI and NBNA were not signiifcantly different between groups with or without poor outcome. Conclusions Threshold TSB is an independent risk factor of poor outcome in full-term newborns with severe hyperbilirubinemia. BIND score is a very good predictor of outcome. TSB threshold, USB and B/A ratio are the predictors of outcome, but their diagnostic values are limited. NBNA, hearing screening and hyperintense globus pallidus on T1W1 in the acute phase of jaundice might not related with neurologic prognosis.
4. Clinical significance of plasma MMP-9, VEGF and vWF in patients with cerebral infarction
Chinese Journal of Cerebrovascular Diseases 2006;3(8):365-368
Objective: To discuss the clinical significance of plasma von Willebrand factor (vWF), vascular endothelial growth factor (VEGF), and matrix metalloproteinase-9 (MMP-9) in patients with cerebral infarction in the process of occurrence and development of cerebral infarction. Methods: Thirty patients with cerebral infarction were divided into 3 groups according to their size of infarction: large infarction, moderate infarction, and small infarction (ten patients in each group). Enzyme-linked immunoadsordent assay (ELISA) was used to detect the concentrations of plasma vWF, VEGF, and MMP-9 in patient with cerebral infarction and in 20 healthy controls on day 1, 3, 7, and 15. Results: The mean levels of vWF (216 ± 62) μg/L, VEGF (584 ± 151) ng/ L, and MMP-9 (287 ± 147) μg/L in the cerebral infarction groups were significantly higher than those in the control group [vWF (96 ± 12) μg/ L, VEGF (111 ± 17) ng /L, and MMP-9 (102 ± 14) μg/L; P < 0.01]. The changes of plasma concentrations of the above 3 factors were correlated positively with the volume of cerebral infarction at the same time point in early cerebral infarction (r = 0.496, r = 0.519, r = 0.472 respectively; all P < 0.01). Conclusion: The concentrations of plasma vWF, VEGF, and MMP-9 were associated with the volume of cerebral infarction.

Objective To study the protective effects of garlic polysaecharide on L02 from oxidative injury.Methods Cultured L02 were injured by ethanol.Various concentrations of GP(10、20、40、80 mg/L) were added into culture medium.Then the cellular MDA,SOD,and GSH-Px were determined in order to observe the protection of curcumin and the time-dose-response effects.Meanwhile,HO-1 mRNA was detected by RT-PCR method after ethanol exposure.The expressions of HO- 1 proteins were detected by Western blotling.Results GP (10、20、40、80 mg/L) could reduce oxidative injury induced by ethanol in L02 cells.Liver cells were 100 mmol/L alcohol after 8h exposure,SOD[(3.65±0.42) NU/mg,(4.11±0.16) NU/mg,(4.61 ±0.23)NU/mg],GSH-Px [ (75.96 ± 8.96) mg/mg,(81.83±5.70) mg/mg,(89.32±6.35) mg/mg respectively],GSH-Px[(75.96±8.96),(81.83±5.70),(89.32±6.35) respectively]activity,MDA[(1.05±0.16) nmol/mg,(0.99± 0.12) nmol/mg; (0.78± 0.11) nmol/mg respectively]levels compared with the control group [ (2.35 ±0.28) NU/mg,(54.41 ±8.17) mg/mg,(1.58±0.23) nmol/mg respectively],there was a significant difference (P< 0.05 ); HO-1 mRNA expression was in a concentration- dependent effect.Conclusion GP had protective effects on L02 from oxidative injury probably by reducing GSH consumption,improving antioxidant enzyme activity and inhibiting lipid peroxidation reaction at dose-dependent manner.GP could promote expression of HO-1 mRNA co-coordinating role in protecting liver cells from oxidative injury.

Objective To screen and identify the serum biomarker of anovulatory dysfunctional uterine bleeding (ADUB) , to determine the expression of biomarker protein in menses of ADUB pa-tients, and to investigate the relation between ADUB and the biomarker proteins. Methods Subjects included 128 ADUB patients and 93 age-matched controls( normal women ). Their serum and super-natant of mense were collected and stored for use at -80℃. The differential proteins in the serum of the 2 groups were detected by CM 10 and analyzed by Biomarker WizardTM3.2 software. Then, the differential proteins were identified by Trieine-SDS-PAGE gel separation, spectrometry identifica-tion, and immunoprecipitation. The expression of the protein identified above in the menses was test-ed by ELISA, RT-PCR, and Western blotting. SPSS 14.1 was applied for statistical analysis and chart drawing. Results Five differential protein peaks were screened and their peak values were 11.80, 13.59, 13.79, 13.85, and 14.20 km/z, respectively. The intensity of protein peak ( 11.80 km/z ) which was identified as serum amyploid protein A ( SAA ) of ADUB was significantly higher than that of the controls (P<0.05). While the intensity of protein peak (13.59 km/z) which was identified as vascular endothelial growth factor (VEGF) of ADUB was obviously lower than that of the controls (P<0.05). The intensity of protein peak 13.08, 13.85, and 14.20 was not different between the cases and controls. SAA expressed highly in the menses of ADUB but low in that of the controls. Conversely, VEGF expressed highly in the menses of the control but low in that of the ADUB. Conclusion Two biomarkers which might be related with ADUB have been correctly screened and identified as SAA and VEGF. It needs further study whether the increased expression of SAA and reduced expression of VEGF are the cause or result of ADUB.
