Objective To introduce a new field-based operating astral lamp. Methods The operating astral lamp employs specially -designed LED as the main light source, and IC as the control circuit. All the components are arranged in a combinatorial structure. It uses no glass material and makes the most of light plastic materials instead of metal. Results By testing the use of it in field training, this astral lamp proves to possess the following traits that high efficiency of light-emitting and low heat and thermal radiation, small power consumption affording a long time of use, strong abilities for vibration and shock resistance, and light-weighted conformation and easy assembly providing a convenient portability. Conclusion It is very suitable for field patrolling and defending.

A systematic analysis of the typeⅢ secretion genes of Aeromonas hydrophila strain AH-1 by constructing ahyR and ahyI mutant revealed that they are under quorum-sensing control. This observation was supported by the down-regulation of the TTSS genes in the presence of lacZ-TTSS gene promoter and the corresponding advanced secretion of AexT in ahyI mutant.

Objective To establish a suitable index system for typhoon disaster relief training of nurses.Methods Based on literature review and semi-structure expert interview,an index system frame work of typhoon disaster relief training of nurses was developed.Indexes were determined by adopting Delphi method and inquiring 21 experts with questionnaire.The weight of every index had been set up.Results The index system for typhoon disaster relief training of nurses was composed of 6 flintlevel indicators,28 second-level indicators and 37 third-level indicators.Conclusions The index system for typhoon disaster relief training of nurses is reliable and valid,which can provide objective and quantitative standards for the employment,training and evaluation of emergency specialized nurses.

The history of portable medical endoscope was studied,and the key technologies was introduced on five modules of power supply,front-end acquisition,cold light source,back-end processing and wireless transmission.The application of the latest technologies of image sensor,image acquisition circuit,image processing circuit,wireless transmission and etc was analyzed in above key technologies.The developing trend of portable medical endoscope was pointed out.

Objective To introduce a puncture-drainage system for intracranial hematoma, which can be used in both peacetime and wartime. Methods The inserting-style connections were taken to design the catheter needle and driller. In the design of the combined T-piece, silica membrane was used to be the main sealing end. The fixed division between the main sealing end and the catheter needle took thread connections. The angle between the side-tube of the T-piece and the catheter needle was 120 degree; the side-tube of the T-piece and the Y-tube also took thread connections. The another two sides of Y-tube linked to different drainage bag and syringe, and all of the hoses got the individual and portable switches. Results This system was more efficient, rapid, safe and convenient. What's more, the injury was minimal when doctor performed an intracranial hematoma puncture surgery by using the puncture-drainage system. Conclusion It is very easy to operate and suitable to puncture drainage for intracranial hematoma surgery in both peacetime and wartime.

Objective To design a wireless oxygen concentration monitoring device to solve the existing problems.Methods The device was composed of an oxygen sensor,an oxygen sensor line,an oxygen concentration monitoring host and a display terminal.HT67F489 was used as the main control chip,KE-25 oxygen concentration sensor was applied to collecting oxygen concentration data,and then through the T82 module wireless transmission of the data was executed to the display terminal of the App software.Results Clinical trials proved the measure value by the device was the same to that by the equipped meter,which facilitated the medical engineer find the faults in the shortest time.Conclusion The device gains advantages in easy installation,stable performances,high accuracy and anti-interference against physical environment,and thus has high social and economic benefits.

Objective To design an endoscopic image acquisition system.Methods High resolution CCD image sensor was used as the image acquisition equipment to converse the optical signals into electrical ones. Data were stored with FPGA controller after ADC, and then transmitted to the computer with PCI bus,Results Trials proved that the system could acquire clear and stable image with simple structure and easy operation.Conclusion The system can acquire high-quality images for the diagnosis and treatment of endoscope.

Objective To study the changes and significance of sCD14 in inflammatory response of patients with gouty arthritis.Methods CD14 mRNA was measured using quantitative real-time PCR in peripheral blood mononuclear cells (PBMCs).The expression of CD14 mRNA in PBMCs was compared between patients with acute gouty arthritis (AGA)(n =31)and non-acute gouty arthritis (NAGA)(n =23)and healthy controls (HC)(n =20).β-actin was selected as the internal control.The protein expressions of sCD14,IL-1βand TNF-αwere measured using enzyme linked immunosorbent assay (ELISA) in patients’ plasma.The protein expression of CRP was measured using immunoturbidimetry in patients’ plasma. Routine blood and blood biochemistry indexes were measured by routine blood analyzer and blood biochemistry analyzer of patients with AGA,NAGA and HC.We analyzed the correlation between CD14 mRNA,sCD14 protein expression and each clinical indicator.Results When compared with that in AGA group,the mRNA expression of CD14 increased significantly in PBMCs of HC patients (P < 0.05 ).When compared with that in HC and NAGA patients,the protein expression of sCD14 increased significantly in the plasma of AGA patients (P <0.01).The protein expression of sCD14 was significantly lower in the plasma of NAGA than in HC (P <0.05).The protein expression of sCD14 increased significantly in the plasma of AGA compared with HC and NAGA (P < 0.01 ).When compared with those in HC,the protein expressions of IL-1β and TNF-α increased significantly in the plasma of AGA and NAGA (P < 0.01 ).When compared with that in NAGA,the protein expression of IL-1βincreased significantly in plasma of AGA (P <0.01). The indexes of WBC increased significantly in AGA compared with HC (P <0.01),and WBC increased significantly in NAGA compared with HC (P <0.05).The indexes of GR and MO increased significantly in AGA compared with HC (P <0.05),and MO increased significantly in AGA compared with NAGA (P < 0.05 ).The indexes of UA increased significantly in AGA and NAGA compared with HC (P <0.01).There was a positive correlation between CD14 mRNA expression and IL-1β in PBMCs in AGA group (r s =0.362,P =0.045).A positive correlation was found between GR and the protein expression of sCD14 in NAGA patients’plasma (r s = 0.397,P = 0.030 ). Conclusion The dysregulated expressions of CD14 mRNA in PBMCs and sCD14 protein in GA show that sCD14 may play a significantly regulatory role in inflammatory reaction.
