This paper describes the basic theories and means of fuzzy logic fault diagnosis. Aiming at the faults that appears in air heater,the fuzzy relation matrix used for its fault diagnosis is constructed. Based on that,the air heater fault diagnosis examples are given. Application results show that it is feasible to apply the method of fuzzy diagnosis to diagnose air heater faults and the method is simple and valid.

Objective Nowadays,with the development of medical vehicle,there are many parameters for inspection in its interior.It has disadvantages,such as complex routing and low system reliability,to use DCS.CAN bus technology can decrease routing and enhance system reliability.Methods OPC technology was used.A temperature supervisor control program and a database application were designed by VB,and the temperature was control by the fuzzy control methods.Results The temperature supervisor control system was established with CAN bus to explore the application of CAN bus in the medical vehicle.Conclusion It can enhance the system's reliability to use CAN bus technology in the medical vehicle.

This paper describes a small—scale air purifier.It is composed of air filteration unit;bactericidal x-ray unit,drug releasing unit and air feeding unit ect.Powered byvehical battery cell,it produces clean and fragrant air after the process of dast removing,smoke -filtering,bactericide and deodorising.It can give out clean air 200m~3/h,it fit for the air purifying in the vehical、hospital and family living room.

Objective To design a pressure detection and control system in the medical compartment for bio-agent casualty emergency evacuation and en route treatment during responses to biological warfare or terrorist attack.Methods An instrument and a pressure transmitter were used for detection,display and alarm of positive and negative pressures in the medical compartment,and pulse width modulation was involved in to regulate fan speed and then to control the pressure inthe compartment.Results The system proved its ability to evacuate bio-agent casualty and fulminating infectious patient with no pollution to the environment.Conclusion The system realizes on-line monitoring of the filter absorber in the medical compartment,enhances the efficiency and reliability of casualty care and thus gains high military benefits.

It was pointed out in this paper that the nature of values was invisible knowledge by analyzing the rela-tion between values and invisible knowledge,and the measures were put forward for constructing the values in medi-cal staff in view of their value construction process and its influencing factors.

Tacit knowledge is critical to a hospital's scientific and technological innovation, the basis for its survival and the major driving force for its sustainable development. It constitutes the bulk of a hospital's knowledge, including chiefly technological elements, cognitive elements, experience elements. emotional elements and belief elements, has priority among its various tasks, and is the basis for and the key to the development of individual and organizational abilities to innovate. The instruction on and inheritance of tacit knowledge plays a key part in the cultivation of innovative talents in a hospital. Thus hospitals ought to strengthen the management of tacit knowledge and realize its exchange and sharing through face-to-face communication, post rotation, the establishment of cross-disciplinary teams and electronic networks, and the coding of tacit knowledge.

A mobile operating room information management system with electronic medical record (EMR) is designed to improve work efficiency and to enhance the patient information sharing. In the operating room, this system acquires the information from various medical devices through the Client/Server (C/S) pattern, and automatically generates XML-based EMR. Outside the operating room, this system provides information access service by using the Browser/Server (B/S) pattern. Software test shows that this system can correctly collect medical information from equipment and clearly display the real-time waveform. By achieving surgery records with higher quality and sharing the information among mobile medical units, this system can effectively reduce doctors' workload and promote the information construction of the field hospital.

To compare the growth factors mRNA expressions in human skin fibroblasts cultured in two (2D) or three dimensional systems (3D). Human skin fibroblasts were isolated and cultured in collagen jelly (3D) or the regular culture plates (2D). After 72 hours, the total RNA of fibroblasts were extracted. Specific oligonucleotide primers for the growth factor VEGF and bFGF were synthesized and reverse transcriptase polymerase chain reaction (RT PCR) was utilized to amplify the mRNA of those growth factors. RT PCR productions were separated by electrophoresis in 1% wt/vol agarose gels and photographed. Semi quantitative data were statistically analyzed. Although the morphology of fibroblasts in 3D culture was different from that in 2D culture, the RT PCR analysis revealed the same expression and concentration of VEGF mRNA and bFGF mRNA in human skin fibroblasts cultured in different systems.

Objective To construct active recombinant cas pa ses-3 gene(r-caspases-3)eukaryotic expression plasmid and observe the apoptos is inducing activity of r-caspase-3 in pancreatic carcinoma cells. Methods pcDNA3.1(+)/r-caspase-3 was constructed and pan creatic carcinoma cells(PC-Ⅱ)were transfected with the pcDNA3.1(+)/r-caspases -3 by liposomes(LipofectAMINE).The expression of r-Caspase-3 mRNA in pancreat ic carcinoma cells was detected by reverse transcription process of the polymera se chain reaction(RT-PCR), and the signs of apoptosis were examined in pancreat ic carcinoma cells by the methods of the DNA electrophoresis and flow cytometry analysis(FACS).Results The sequence inserted in pBlueSKM/r-Caspase-3 p lasmid was coincident with that of the r-caspases-3. The evaluation result of pcDNA3.1(+)/r-caspases-3 through enzyme cutting was correct. A 894bp strap was observed by RT-PCR after pancreatic carcinoma cells being transfected with the pcDNA3.1(+)/r-caspases-3 by liposomes. No strap was found in control groups. A characteristic DNA ladder was observed in pancreatic carcinoma cells DNA elect r ophoresis, and transparent hypodiploid karyotype peak was found by FACS. Conclusion The plasmid of pcDNA3.1(+)/r-Caspase-3 was c onstructed successfully, the expression of r-Caspase-3 mRMA in pancreatic carc inoma cells was confirmed by RT-PCR, and pcDNA3.1(+)/r-Caspase-3 can induce a poptosis in pancreatic carcinoma cells.
