ABSTRACT
Objective:To explore the influencing factors of acute bilirubin encephalopathy (ABE) in neonates with severe hyperbilirubinemia.Methods:A total of 123 cases of severe neonatal hyperbilirubinemia (serum total bilirubin > 342 μmol/L) in our hospital from January 2018 to May 2020 were retrospectively analyzed.According to the occurrence of ABE, they were divided into ABE group (28 cases) and non-ABE group (95 cases). The perinatal data and laboratory examination results between two groups were compared.The variables with statistical differences in univariate analysis were included in multivariate Logistic regression analysis.Results:Univariate analysis showed that the hemoglobin level and hematocrit of ABE group were higher than those of non-ABE group.The total bilirubin value, length of hospital stay, natural childbirth, mixed feeding, infection with craniocerebral hemorrhage were all higher than those in the non-ABE group, and the differences were statistically significant( P<0.05). Multivariate Logistic regression analysis showed that high hemoglobin level ( OR=1.032, 95% CI 1.007 to 1.057) and long hospital stay ( OR=1.15, 95% CI 1.007 to 1.312) were independent risk factors for ABE patients.Breastfeeding was a protective factor for ABE patients( OR=0.151, 95% CI 0.028 to 0.821). Conclusion:High hemoglobin value and long hospital stay are independent risk factors for ABE patients, and breast feeding is a protective factor for ABE.
ABSTRACT
AIM:To investigate the RNA oxidative damage in human gastric cancer tissue and para-carcinoma tissue for exploring the role of RNA oxidation in the occurrence of gastric cancer .METHODS:Immunohistochemical ob-servation and LC-MS/MS analysis were performed in 61 cases of gastric carcinoma .The position and concentration of 8-oxoguanosine ( 8-oxoGsn ) were detected , respectively . RESULTS: The results of immunohistochemical observation showed that 8-oxoGsn was obviously up-regulated in the gastric cancer .The positive staining mainly accumulated in the cy-toplasm of the tumor cells .The results of mass spectrometry showed that the level of 8-oxoGsn in the gastric cancer tissues was higher than that in the para-carcinoma tissues (P<0.05).CONCLUSION:8-oxoGsn is up-regulated in gastric canc-er.RNA oxidative damage may play important roles in the occurrence of gastric cancer .
