RESUMEN
Objective: To investigate the prevalence and risk factors of congenital heart disease inYunnan, China which has diverse ethnic groups. Methods: This cross-sectional studyenrolled 244,023 children from 2010 to 2015. To diagnose CHD, a conventional physicalexamination was used to screen suspicious cases, which were further confirmed byechocardiography. Results: A total of 1695 children were diagnosed with CHD. Theestimated prevalence was 6.94%. Atrial septal defects were the most common cardiacabnormalities. A higher prevalence of CHD was observed with preterm birth, low birthweight, maternal age ≥35 years, and high-altitude regions. The prevalence also showeddifferences between diverse ethnic groups. Conclusion: The prevalence of CHD in Chinamay have ethnic differences.
RESUMEN
OBJECTIVE@#In order to explore the relationship between the expression change of cytokines and the wound age during the healing process of rats skin wound.@*METHODS@#A assay of ELISA were performed on intravital skin wounds(after incision 0.5-168 h) to detect the dynamics expression level of IL-2, TNF-alpha.@*RESULTS@#The level of IL-2 and TNF-alpha increased at 0.5 h after wounding, then got to a peak at 3 h and 1 h after injure respectively. Rebound of TNF and IL-2 levels were shown at 48 h after wounding, and both cytokine levels were inclined to elevating between 72 h and 168 h after wounding.@*CONCLUSION@#The cytokine level changes suggest they have a time-related expression during wounds healing process.
