Objective To analyze the situation of infections of bacteria and multi-drug resistant bacteria in Department of Neurology of First Affiliated Hospital of Chongqing Medical University from January 2010 to December 2012.Methods Clinical data from 2010-2012 were obtained via Doctor Workstation system and Excel software was applied to analyze the bacteria subto-tals sites,classifications and drug resistance rates.Results The rate of hospital bacterial infection decreased from 4.99% in 2010 to 3.41% 2013,while the composition of the bacterial infection sites exhibits no significant change.Staphylococcus aureus accounts for the major gram-positive bacterial infections,while E.coli contribute to gram-negative bacteria infections.Moreover,the ranking in the three years did not change significantly.In addition,the rate of Acinetobacter baumannii and Pseudomonas aeruginosa increased. Conclusion Our department has achieved some success in the control of bacterial infection in the past three years,however the situ-ation remains to be difficult.

The normal structure of axonal terminals in lamina V of cervical spinal cordof the adult rat was examined with EM.Among 4039 various types of terminals inlamina V,the terminals with clear round synaptic vesicles(R)and the terminalswith clear flat synaptic vesicles(F)constitute about 40% each,the terminals withlarge granular vesicles(LG)about 16% and the central terminals of syntapticglomeruli about 3%.In addition,about 3.2% of the various types of terminalscontain neurofilaments,about 0.9% exhibit low electron dense axoplasm and thevesicles are partly lost or clumping.The synapses of the terminals in lamina V aremainly axodendritic,a small number of them are axoaxonal.There are more F,fewer R and LG in lamina V than those in lamina Ⅱ;thesynapses between the terminals and proximal dendrites,and axosomatic synapses aremore commonly seen in lamina V than in Ⅱ.
