[Objective]To develop a mini-pressure-sensor(MPS)for measurement of plantar pressure(PP)and to evaluate its clinical application.[Method]The MPS was installed in the shoes,and computer was used to accumulate and analyze the change of PP in whole walking stage.Pathologic changes of PP in clinical patients were also analyzed by MPS.[Result]In normal walking,the PP of forefoot was 49% of body weight(BW)and of midfoot and heel was totally 51% of BW,but at pathologic state,the equilibrium of walking was dynamically disrapted inducing a pathologic changes of foot bearing.[Conclusion]Self-developed MPS for measuring PP is help for dynamic analysis of normal PP and is valuable to recognize the pathologic distribution of PP in pathological state and to provide a guide for treatment.

Literatures about patella fracture fixation in recent years are analyzed retrospectively in this paper.Its characteristics and therapeutic purpose are investigated.A series of new type of internal fixations and external fixations are emphasized.

Aim To observe the effect of Sinomenine on the activation of NF-?B and the degradation of its inhibitor I-?B in peritoneal macrophages of BALB/c mice in vitro and provide experimental evidence for further evaluation of the antiinflammatory and antirheumatic effects of Sinomenine. Methods Effect of Sinomenine on the activation of NF-?B p65 in the cells was investigated by using fluorescence-labelling and laser confocal scanning microscopy; Effect of Sinomenine on the degradation of I?B-? was investigated by Western blot. Results SIN (0.25,1.25 mmol?L -1) attenuated the activation of NF-?B p65 in peritoneal macrophages of BALB/c mice induced by LPS in vitro. SIN(0.25,1.25 mmol?L -1) inhibited the degradation of I-?B-? in peritoneal macrophages of BALB/c mice induced by LPS in vitro. Conclusion SIN can partially inhibit the activation of NF-?B p65 and the degradation of I?B-? in peritoneal macrophages of BALB/c mice induced by LPS in vitro.

Objective To evaluate the value of 2D ultrasound and elastic strain ratio (SR) in diagnosis of thyroid nodule by fine needle aspiration (FNA).Methods 196 thyroid nodules were analyzed retrospectively with 2D ultrasound,elastography and FNA results,pathology results as the golden standard.A receiver operating characteristic (ROC) curve was used to identify the best cut-off point of SR.The Logistic regression analysis was used to evaluate the variables effectiveness on age,nodule echo,calcification and SR.Tried to discuss how to use SR before or after US-FNA in diagnosis of thyroid nodule.Results The SR of the malignant nodules group was significantly different from the benign nodules group,and the best cut-off point was 0.5 with sensitivity 91.7％,specificity 90.2 ％ and accuracy 90.8 ％.The Logistic analysis results were SR,age,echo,calcification according to the odds ratio.SR can screened nodules without puncture necessary before FNA,and increase the FNA sensitivity,specificity and accuracy after FNA.Conclusions SR has good application value in diagnosis thyroid malignant tumor.SR can reduce unnecessary FNA and make a supplementary diagnosis of FNA.

The information was obtained through the open access channels and organized with free markers.The relations in research and development institutions of foreign military medical equipments were determined by analy-zing thecompetitive opponents .The information platform for research and development institutions of foreign mili-tarymedical equipments was constructed using the MVC design model in combination with Web2.0 technology and community concept of resources according to the B/S structure forthe collection, storage, organization, analysis, sharing and evaluation of military medical information resources .

Objective To build a three-dimension finite-element model of patella and to make a preliminary mechanics analysis on the model.Methods According to the model-building principle of Ansys software which started from point to line to area to volume,a three-dimension finite-element patella model was reconstructed on the basis of the images of spiral CT.Then,loading on the model patella were simulated and the stress magnitude and distribution on the patella were analyzed.Results Finite element analysis of the patella showed that stress concentration zone located in the middle and lower patella,indicating that fracturepredilectionsitesinthelower patellar.TheVon misesstresson thetensionsidewas significantly greater than that on pressure side.Conclusion The established finite element model of the patella can reflect the real geometry of patella treated in clinics.

Syndromic surveillance , based on non-specific pre-diagnosis and other information , is capable of nearly real-time detection and early warning of potential bioterrorism and emerging infectious threats .Developed countries , led by the U.S., have conducted in-depth and front research in this area while China has just started syndromic surveillance re -search in the exploratory trial stage .The Chinese army is facing an urgent need for syndromic surveillance .This paper makes a case study of foreign military syndromic surveillance practices , typically the U.S.representative system ESSENSE , which was developed by the U .S.Department of Defense and deployed in all military treatment facilities .Some suggestions for the Chinese army are also discussed .

The practical experiences with subject service in Medical Library of Chinese PLA were summarized in terms of the establishment of user information records, accumulation and summation of information, and construc-tion of information platform. Suggestions were put forward for the improvement of subject service in Medical Library of Chinese PLA, such as holding the big information concept in the big data era, using the biomedical data as the target of study, providing various kinds of service, integrating seamless, dynamic and interactive library service into user service. The fact that focus on artificial intelligence, computer, information and coomunication technologies is one of the future directions was pointed out.

In educating postgraduate students in aerospace medicine in our country, there are some deficiencies such as the course content lacking forward looking and systematicness, and students' mastery of technology or skills lacking professional characteristics, innovation and divergent thinking. Based on the original foundations, the School of Aerospace Medicine, Fourth Military Medical University, has been con-structing and improving the course system by modifying the course contents, reforming the practical teach-ings, expanding the academic communications, and managing the processes. Finally, they have achieved certain results.
