Objective:To explore the value of arterial blood gas analysis and electrolyte determination in the diagnosis of neonatal asphyxia.Methods: A total of 100 neonates with asphyxia who were admitted in our department from March, 2013 to March, 2014 were included in the study and divided into the mild asphyxia group and the severe asphyxia group according to Apgar scoring. Moreover, 50 normal neonates were served as the control group and used for comparative analysis. AVL blood-gas analyzer was used to detect the levels of pH, PaO2, HCO3-, BE, PaCO2, K+, Na+, Cl-, and Ca2+.Results:The concentrations of pH, PaO2, HCO3-, and BE in the severe asphyxia group were significantly lower than those in the mild asphyxia group and the control group, while PaCO2 level was significantly higher than that in the mild asphyxia group and the control group. The comparison of the various indicators between the control group and the mild asphyxia group was not statistically significant. The comparison of serum K+, Na+,and Cl- levels among the control group, the mild asphyxia group, and the severe asphyxia group was not statistically significant. The serum Ca2+ level in the severe asphyxia group was significantly lower than that in the mild asphyxia group and the control group, while the comparison between the mild asphyxia group and the control group was also statistically significant.Conclusions:Blood gas analysis and electrolyte determination to the arterial blood in neonates can compensate for the insufficiency of Apgar scoring and provide an objective evidence for the diagnosis of neonatal asphyxia and the estimation of severity degree. Clinical combination with Apgar scoring is of great significance in enhancing the diagnosis of neonatal asphyxia and the accuracy of severity evaluation.

Objective:To explore molecular mechanism and biological function of miR-155 and its target genes on endometriosis.Methods: The expression of miR-155 in Ems patient and healthy control were assayed by RT-PCR. After miR-155 mimic and inhibitor were transfected into Ems endometrial cells for 48 h, the viability of cell was detected by MTT assay. Transwell migration and invasion assay were used to detect cell migration and invasion. The expression of cell apoptotic protein Bax and Bcl-2, matrix metalloproteinase (MMP 2) and MMP 9 were assayed by western blot.Results: The expression of miR-155 in Ems patient was more than that in the health control (P<0.01). After miR-155 mimic and inhibitor were transfected into Ems endometrial cells for 48 h, miR-155 over-expression could increase cell viability, and promoted cell migration and invasion, which was related to down-regulation of Bax along with up-regulation of Bcl-2, MMP 2 and MMP 9.Conclusion:These results suggested miR-155 lower expression inhibit endometrial cell proliferation and migration of the Ems.
