ObjectiveTo investigate the clinical effects of systems integrative rehabilitation therapy for cervival spdylotsis myelopathy.MethodsFrom April 2002 to October 2004, 68 cases were intervened with the integrative rehabilitation treatment, which linked up the pre- and post-operational rehabilitation interventions into a continuum. The cases were followed up, and serial radiological evaluations were applied. Then the height of involved interspinal space was measured preoperatively and 12 months after operation, and the spinal function was evaluated according to the standard of Japanese Orthopeadic Association (JOA).ResultsAll the cases were followed up, of which 49 were better, 1 was improved, none was worsened. 12 months after operation, roentgenographic appearance showed that the allograft healing and interbody fusion of all patients were achieved, and the reserving height of involved interspinal space and JOA evaluation postoperatively were significantly superior to preoperatively. There was no complications such as cervical spinal cord injury, internal fixation loosening and hematoma turned up.ConclusionThe integration rehabilitation therapy has satisfactory effects in the cervical spondylotsis myelopathy.

Objective To develop perfluorocarbon lipid particles and investigate their basic properties,and target them to human hepatocellular carcinoma cells in vitro by hepatoma monocolonal antibody HAb18 with avidin-biotin interaction.Methods Rotary evaporation and high pressure homogen were used to prepare perfluorocarbon lipid particles, and the appearance and distribution of them were investigated by microscope and electron microscope, the concentration and the size and electric potential were detected.The biotinylated monoclonal antibody HAbl8 was prepared, then the biotinylated degree of the antibody was determined.The biotinylated perfluoroearbon lipid particles labelled with NBD were prepared and targeted to human hepatocellular carcinoma cells in vitro with avidin-biotin interaction.Results These perfluorocarbon lipid nanoparticles were uniform and stable,and the mean diameter of them was 171.9 nm.Hepatocellular carcinoma cells were surrounded by the biotinylated particles labelled with NBD.Conclusions A steady perfluoroearbon lipid particles were prepared and the biotinylated particles can be targeted to hepatocellular carcinoma cells with avidin-biotin interaction.

OBJECTIVE To analyze the pathogen distribution and resistance pattern of the positive clinical sputum specimens in our hospital.METHODS The bacteria and fungi were identified by API system.The susceptibility of antimicrobial and antifungal agents was tested by KB and Rosco disk diffusion method and the data were analyzed by WHONET 5.4 software.RESULTS In 2008,in our hospital,the majority of the positive specimens were distributed among cerebral surgery department,intensive care unit(ICU),respiratory and pediatric departments.The pathogens of the eight highest isolating rate were Pseudomonas aeruginosa(20%),Candida albicans(18%),Acinetobacter baumannii(10.7%),Staphylococcus aureus(6.5%),Klebsiella pneumoniae(6%),Enterobacter cloacae(4%),Haemophilus influenzae(3.8%),and Stenotropho maltophilia(3.5%).In view of the resistance,no Staphylococcus species were resistant to vancomycin,but they were resistant to many other antimicrobial agents.Gram-negative Enterobactericaeae were sensitive to carbapenems,cefoperazone/sulbactam and piperacillin/tazobactam.Among nonfermenters,P.aeruginosa and S.maltophilia were resistant to the most antimicrobial agents while Acinetobacter were comparatively sensitive to carbapenems and cefoperazone/sulbactam.CONCLUSIONS The pathogens in lower respiratory tract infections have a high resistance rate to many antimicrobial agents.In view of the seriousness of this problem,we should emphasis on it and select antimicrobial agents rationally.

Objective:To discuss the medical support strategy by summarizing the experience of medical support in Dongfeng landing site.Methods:According to the current situation of medical support at Dongfeng landing site and the practice and experience of previous medical support, a retrospective summary study was conducted.Results:The main methods were summarized: (1) formulate a feasible plan; (2) strictly screen skilled personnel; (3) provide reasonable medicinal materials and equipments; (4) complete the modification of the rescue carrier; (5) attach importance to the training of first aid techniques; (6) strengthen political and ideological education; (7) carry out physical fitness training; (8) seriously participate in actual combat training. Three points of experience were put forward: (1) the importance of thinking and action is the premise of completing the task; (2) the cooperation between training and actual combat is the basis for completing the task; (3) equal emphasis on education and management is the bottom line for completing the task.Conclusions:The medical support experience of the Dongfeng landing site is summarized to provide support and experience for the long-term in-orbit operation of China's space station and on-site medical rescue after the landing of the manned spacecraft.
