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.

5. 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.
