We report a 21-month-old child with spontaneous pneumomediastinum (PM), emphysema, and pulmonary bullae caused by Mycoplasma pneumonia (M. pneumoniae) pneumonia. The patient presented with stubborn dyspnea and wheezing although received integrated treatment, including anti-infection, anti-inflammation, and intravenous immunoglobulin. This case was unique in that pulmonary bullae kept increasing. PM and emphysema were refractory in our patient, which have been reported as benign and limited. Surgical intervention was implemented to ultimately cure the case. Clinicians should be aware of air leaks in patients with M. pneumoniae pneumonia since this complication may be fatal.

The earthquake emergency succor is a system engineering with cross-sectoral, multi-disciplinarity and multi-domain, which needs a rapid emergency response capability. The earthquake emergency rescue geography support platform construction conception has been put forward based on the earthquake emergency rescue in our country's present situation and the needs of the business by this thesis. The seismic spatial data has been considered as the support basic data for the earthquake emergency rescue geography support platform, and the professional seismic analysis model and the advanced GIS geographic platform technology as the technical support. Besides, the map has been considered as the main information carrier in order to offer the professional and authoritative disaster information to all kinds of audience personnel during the earthquake emergency succor.
