EISAs (n = 20), showed a significant reduction of BPD (29.0 vs. 70.0%, p = 0.004) and PDA (29.0 vs. 65.0%, p = 0.011). In the subgroup analysis of blood gas, arterial oxygen saturation (SaO 2) value at 1 and 12 h and partial pressure of arterial oxygen (PaO 2) at 12 h were all higher in the EISA group compared to the MISA group. Conclusion : MISA had no clear benefit on the incidence of BPD, but it was related to a reduction in PDA. It is an appropriate therapy for spontaneous breathing in infants with extremely low birth weight and NRDS.
Our analysis demonstrated the decreased incidence and increased survival rate of GC. In addition, lower SES was associated with lower survival rates. It is notable that others (primarily for Asians) had the highest incidence rate but had better outcomes than Whites and Blacks.
The aim of the present study was to investigate the effect of coronary artery angioplasty on the recruitment of circulating endothelial progenitor cells (EPCs) in patients with angina pectoris. A total of 66 patients treated by coronary stenting were enrolled in the PCI group and 17 patients that underwent angiography alone were enrolled in the control group. The EPC count in the blood was measured by flow cytometry prior to and at 1, 3, 5, 7 and 24 h following angioplasty in the percutaneous coronary intervention (PCI) group, and at three time-points following angiography in the control group. Differences between the two groups included the characteristics of the coronary artery lesions, the incidence of diabetes and family history of coronary heart disease. The mean surface area of the stent deployed was 335.59±234.99 mm. No significant change in EPC count was measured in the control group. In the PCI group, a moderate and delayed increase in the number of cluster of differentiation (CD)34/kinase domain receptor (KDR) EPCs occurred at 24 h post-balloon inflation compared with the baseline level. The CD133/CD34/KDR subpopulations showed undulating changes at 3, 7 and 24 h post-PCI (P=0.016, P=0.01 and P=0.032, respectively). An arch shape was displayed in CD133/KDR cells; initially, a reduction occurred at 3 h and was maintained constantly until 7 h (P=0.003, P=0.013 and P=0.033 at 3, 5 and 7 h, respectively), after which a slight increase to the baseline level occurred at 24 h (P=0.084). The CD133/CD34 cells increased in stepwise manner until 24 h. The CD34/KDR EPC change magnitude correlated significantly with a global damage index by partial correlation analysis (P<0.001). The results suggested that a time-dependent mobilization of EPCs may be initiated by PCI; the change magnitude of the CD34/KDR cells was associated particularly with endothelial injury degree from the PCI procedure.
BackgroundIt is of high incidence of brain injuries in premature infants, so it is necessary to diagnose and treat the brain injury early for neonatal clinical practice. We are aimed to investigate the relationship between early postnatal cranial ultrasonography and psychomotor and mental development in prematrue infants at the age of 12 months.MethodsTwo-hundred and eight premature infants were selected and underwent follow-up from January, 2007 to November, 2012. Cranial ultrasonography was performed on them. The developmental outcomes of these premature infants at the age of 12 months were assessed by the psychomotor developmental index (PDI) scale and mental development index (MDI). The relationship between ultrasonic gray-scale value and PDI and MDI was analyzed.ResultsThe worse prognosis for psychomotor and mental development was associated with the gestational age, Apgar score(1 min), gender, chorioamnionitis, duration of mechanical ventilation and duration of mechanic ventilation. The differences between the prognosis of psychomotor and mental development, and peri-intraventricular hemorrhage (PIVH) and periventricular white matter damage (PWMD), were statistically significant (P < 0.05). There were also significant differences between the early postnatal ultrasonic gray-scale value and prognoses of both psychomotor development and mental development (P < 0.05). There were negative correlations between ultrasonic gray-scale and both PDI and MDI (r = −0.753, P < 0.05; r = −0.764, P < 0.05).ConclusionsThe early postnatal cranial ultrasonography can assist to predict the prognosis of psychomotor and mental development for premature infants. The higher grade of PIVH and PWMD was associated with the worse prognosis of psychomotor and mental development.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
