Résumé
Objective To design a reproducible solution for municipal population health information platform to solve the problems in multi facilities involved,long construction period and etc.Methods The present situation of municipal health information platform was described as "eight manys and eight insufficiencys",and the solutions of foreign countries and China were explored from the aspects of business and technology architectures as well as the requirements of national population health informatization overall architecture.Results The municipal medical informatization infrastructure optimized regional medical service flow,improved medical resources allocation and enhanced health management.Conclusion Municipal population health information platform contributes to promoting regional medical service to meet increasing public requirements.
Résumé
<p><b>BACKGROUND</b>Polymorphonuclear neutrophil (PMN), one of the most important inflammatory cells, functions throughout the initiation, progression and resolution of inflammation. This study aimed at investigating the relationship between PMN apoptosis and the lung injury after chest impact trauma.</p><p><b>METHODS</b>PMNs were purified from rabbits subjected to the chest impact trauma and their apoptosis, necrosis, survival and respiratory burst were detected by flow cytometry. Meanwhile, lactate dehydrogenase and (LDH) [Ca2+]i were measured.</p><p><b>RESULTS</b>The delayed apoptosis of PMNs in bronchoalveolar lavage fluid was observed from 2 hours to 12 hours after trauma, and viable cells increased. Respiratory burst of PMNs in bronchoalveolar lavage fluid was increased significantly from 2 hours with the peak at 8 hours. Meanwhile, lactate dehydrogenase in bronchoalveolar lavage fluid was higher than that in control (P < 0.05) from 4 hours to 24 hours, and intracellular free Ca2+ in PMN was increased temporarily.</p><p><b>CONCLUSIONS</b>Retention of PMN in tissues and the abnormality in apoptotic pathway inevitably generate persistent activation of PMN and excessive release of toxic substances, resulting in tissue injury. The temporary increase of intracellular free Ca2+ may be responsible for the delayed apoptosis of PMN.</p>
