This study was aimed to objectify Color Inspection in Traditional Chinese Medicine (CITCM). A quantita-tive system for CITCM was designed and developed. The entire system included two parts, which were the hardware and the software. The hardware was an image acquisition device in a standard lighting condition. The software was used for digital image processing. The chromaticity of facial special region (SR) corresponding to five internal organs were calculated. The system was carried out by taking 100 samples of people. It was concluded that the experiment verified the effectiveness of the system in objective study of CITCM. It can be used as basis for the further study on CITCM.

OBJECTIVE To find the cause of lower respiratory tract infection as soon as possible and take measures to control the infection.METHODS The records of hospitalized patients in the intensive care unit(ICU) form Nov 28 to Dec 6 in 2006 were analyzed;and the disinfection efficiency,sterilization effect and the environment were monitored.RESULTS The incidence rate of lower respiratory tract infection was 54.55%.The qualified rate of disinfection and sterilization monitoring was 35.71%.The respiratory tubing,bed handle,bottle openner,computer mouse,the surface of the file cabinet and air vents were heavily infected.The Staphylococcus aureus was isolated from the quilt cover and the surface of the file cabinet.CONCLUSIONS We should put more emphasis on the management of the infective disease in the ICU,on hand washing and the cleanliness and maintenance of the devices.Disinfection and isolation guidelines should be strictly followed to reduce the incident rate of infection in the ICU.
