Objective To study the morbidity rule of community trauma and pre-hospital care mea-sures so as to improve the pre-hospital care performance. Methods 962 cases who received pre-hospital care by "120" commanding center in our hospital were retrospectively analyzed by means of self-designed questionnaires. Results The features of community trauma were mainly multiple trauma caused by traffic accidents, the main pre-hospital care measures included bandaging, hematischesis, pexia, aspiration of oxy-gen,intravenous injection, cardiopulmonary resuscitation,tracheal intubation and cricothyroid puncture,a-mong which bandaging, hematischesis and pexia accounted for 92.7 per cent. Conclusions Early and rapid treatments to the wounded patients, and correct medical rescue are very important. They are the two key factors to promote the success rate of rescue. At the same time, sound nursing management, correct medical treatment and nursing coordination are also critical aspects.

Medical curriculum integration mode is the development trend of medical education re-form. The Institute of Basic Science of Guangzhou Medical University has given full consideration to the present situation at home and abroad and its own conditions, modularized the traditional basic medicine ex-periment course according to the similar content, and formed medical human morphology (human anatomy and tissue embryology, pathology), immune and pathogenic biology (microorganisms, parasites, immunology), biological science (cell biology, genetics, biological sciences) three modules, and then gradually established and perfected a scientific and effective comprehensive morphology experiment teaching material, teaching method, examination and evaluation system based on the teaching content of integration. The establishment of this new basic medical morphology course system, which is based on the organs and systems, shows the less content redundancy, good structural and overall coordination of the new curriculum, so as to play its comprehensive advantages and conform to the trend of the development of the medical education.

The dual luciferase reporter gene system provides sensitive readout, while it relies on a constitutively-expressed control gene for readout normalization. However, most standard control reporter genes are not constitutively expressed under all conditions. Here, we report an effective method to construct a control reporter plasmid for the dual luciferase reporter gene system that would be suitable for hormone research in silkworm cell lines. First, we modified BmVgP78M, a stably-expressed constitutive promoter in silkworm cells by mutating its hormone-related element. Then, we constructed the pRL-VgP78M control reporter plasmid by replacing the SV40 promoter and chimeric intron sequences in pRL-SV40 with the BmVgP78M sequence. Finally, we confirmed that the pRL-VgP78M control reporter plasmid could be stably expressed in silkworm cell lines via cell transfection experiments, and it was unresponsive to the induction of ecdysone, juvenile hormone, or their transcription factors. We thus obtained a control reporter plasmid pRL-VgP78M that could be expressed stably and moderately in silkworm cells. It can be readily used as the control reporter plasmid of the dual luciferase reporter gene system for hormone research in silkworm cell lines. It will also provide a reference for construction of control reporter plasmids of dual luciferase reporter gene systems that are adaptable to cell lines isolated from other species.
