[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.

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.

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.

This study was aimed to analyze four diagnostic methods of AIDS patients with HAART complicated with anemia and hyperlipidemia. Characteristics of traditional Chinese medicine (TCM) and common pathogenesis were discussed in this article. This study was supported by Key Project of the National Eleventh-Five Year Research Program of China. This study was conducted through the retrospective analysis. This analysis was made on the four diagnostic methods of AIDS patients with HAART treatment. The results showed that the most frequent symptoms of AIDS patients with anemia or hyperlipidemia are fatigue, facial abnormalities, taste abnormalities, forgetfulness, backache, weakness of back, loss of appetite, insomnia. And the frequent tongue and pulse are white tough coating, pale tongue and fine pulse. The most frequent symptoms of the anemia group are facial abnormalities, backache, dizziness, palpitations, shortness of breath, pale complexion, abnormal state of mind, abnormal sweating, tinnitus, cold hands and feet, spontaneous sweating, white tongue coating, tooth-printed tongue, thin tongue coating and weak pulse (P < 0.05). The most frequent symptom of hyperlipidemia are lassitude, weakness, loss of appetite, abdominal distension, moisture tongue, thick and greasy tongue coating, slippery pulse. It was concluded that syndromes of AIDS patients on ARV complicated with anemia and hyperlipidemia are mainly deficient pattern, which affects the spleen, heart, liver and kidney. The most frequent syndrome type with anemia patients is blood deficiency, which is followed by spleen-kidney deficiency syndrome, liver-kidney deficiency syndrome. The most frequent syndrome type with hyperlipidemia patients is spleen qi deficiency and kidney essence deficiency, which are closely related to the spleen and kidney.

Aerospace physiology is an important part of aerospace medicine.There are some problems existing in the current practice classes.Microlecture is a new kind of teaching methods.With its advantages, microlecture improved the teaching efficiency, and played a good role in the practice classes for undergraduate students, successfully solving part of the problems and promoting the teaching reform.The microlecture, as an auxiliary means, provides a new way for practice class of aerospace physiology.It`s suggested to be popularized in undergraduate teaching of aerospace medicine.

Objective:To inspect the relationship between the therapeutic effect of DHA on lupus nephritis and the negative immune regulation of TLR4/NF-κB signal pathway which was induced by SIGIRR;in vitro,to observe the effect of DHA on damaged HK-2 cell.Methods: In vivo,MRL/lpr mice were divided in model group,DHA groups(25,50,100 mg/kg),positive group (prednisone,5 mg/kg),and C57BL/6 mice were taken as control group.Administrate drugs daily for 12 weeks.Examine the changes in renal pathology;the expression of SIGIRR,IRAK1,TRAF6 in kidneys were determined by Western blot.In vitro,treat human renal tubular epithelial cell HK-2 cells with LPS ,and co-culture cells with DHA at the concentration of 0.67 μg/ml to 6.00 μg/ml for 6 h, 12 h and 24 h.Detect SIGIRR expression by Western blot and the level of IL-6 and CCL2 of HK-2 cells by ELISA.Results:In vivo, renal pathology revealed that kidneys of model group were damaged , while treatment with 100 mg/kg DHA alleviated renal injury.Compared to model group ,SIGIRR expression of DHA 100 mg/kg group increased a little ,and the expression of this protein had a tendency to increase with the augment of DHA dose .In vitro,DHA treatment reduced secretion of CCL 2 in HK-2 cells,and treatment of 0.67 μg/ml DHA for 24 h increased SIGIRR expression significantly , which also showed a growing expression with time.Conclusion:DHA could inhibit development of mouse lupus nephritis through increasing SIGIRR expression which inhibited TLR4/NF-κB signal pathway;DHA inhibited CCL2 secretion of HK-2 cells which were irritated by LPS ,and it may be associated with increased expression of SIGIRR .

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.
