This article discusses the three-dimensional ambulance under the future war conditions.The unexpectedness of battlefields and complexity of the wounded in the future warfare necessitate the establishment of a three-dimensional system of medical rescue that can be organized by land,water and air.With an analysis of the features of modern war and based on the theory of modern treatment,the authors have proposed the requirements for designing the mode of three-dimensional rescue in the war zone and its typical procedures,set forth the view that rapid reaction and three-dimensional rescue are the most effective medical guarantee of combat strength,and provided a scientific basis for building a medical rescue system in the future warfare.

Teacher student relationship is the most important part in educational activities.It’s quality and quantity have a significant impact on educational and teaching effectiveness.This article aims to analyze the exiting status of the relationship between the tutors and the postgraduates in Peking Union Medical College Hospital, focusing on the some main factors which affect the said relationship, including education environment factor, tutor factor, postgrad-uate factor and etc., and combining the characteristics of Medical Colleges’studying.On the basis of the concerned survey, this article initially discusses the key issues during the establishment of the harmony relationship between tutors and postgraduates.

ObjectiveTo assess the differential diagnostic value of serum intestinal fatty acid binding protein (I-FABP)in distinguishing intestinal ischemia patients from acute abdomen patients.MethodsA total of 151 patients with acute abdomen and 17 healthy controls from the PLA General Hospital were enrolled from November,2009 to August,2011. Serum I-FABP levels were measured by ELISA.According to the ROC curve,the cut-off value,sensitivity,specificity,positive likelihood ratio (PLR),negative likelihood ratio ( NLR),positive predietive value (PPV) and negative predictive value (NPV) were calculated. ResultsOf the 151 acute abdomen patients,there were 24 intestinal ischemia patients and 127 without intestinal ischemia.Serum I-FABP level in intestinal ischemia group [( 109.67 ±48.82) μg/L]was significantly higher than those in patients without intestinal ischemia [(36.78 ± 11.25) μg/L]and healthy controls[(8.33 ±6.25) μg/L]( all P values ＜0.01 ).The serum I-FABP cut-off value for the diagnosis of intestinal ischemia was 87.52 μg/L.Serum I-FABP was efficient in terms of sensitivity (0.762),NPV(0.963),PLR(3.05) and NLR (0.24) in the diagnosis of intestinal ischemia.ConclusionI-FABP is potentially useful for discriminating intestinal ischemia from acute abdomen.

OBJECTIVETo discuss the mechanism of gambogenic acid (GNA) in inducing the apoptosis of melanoma B16 cells.

METHODThe inhibitory effect of GNA on the proliferation of B16 cells was measured by the methyl thiazolyl tetrazolium (MTT) assay. The effect of GNA on B16 cells was detected by the Hoechst 33258 staining. The transmission electron microscopy was used to observe the ultra-structure changes of B16 cells. The changes in PI3K, p-PI3K, Akt, p-Akt, p-mTOR, PTEN proteins were detected by the Western blotting to discuss the molecular mechanism of GNA in inducing the apoptosis of B16 cells.

RESULTGNA showed a significant inhibitory effect in the growth and proliferation of melanoma B16 cells. The cell viability remarkably decreased with the increase of GNA concentration and the extension of the action time. The results of the Hoechst 33258 staining showed that cells processed with GNA demonstrated apparent apoptotic characteristics. Under the transmission electron microscope, B16 cells, after being treated with GNA, showed obvious morphological changes of apoptosis. The Western blot showed a time-dependent reduction in the p-PI3K and p-Akt protein expressions, with no change in p-PI3K and p-Akt protein expression quantities. The p-mTOR protein expression decreased with the extension of time, where as the PTEN protein expression showed a time-dependent increase.

CONCLUSIONGNA could inhibit the proliferation of melanoma B16 cells and induce their apoptosis within certain time and concentration ranges. Its mechanism in inducing the cell apoptosis may be related to PI3K/Akt/mTOR signaling pathways.

In the 40 years of last centry American scientists put forward a concep of high intensity focused ultrasound (HIFU) therapeutic technique and had done some technical and clinical studies. Since 90 years the HIFU surgery technique treating tumors anew rised abruptly in the world. China firstly put out a comprehensive HIFU tumor treating sistem and successfully treated many solid tumors such as breast cancer, bone tumor, liver cancer etc.. Now the treating sistem has already exported to England, Italy,Spain, Japan, Colea etc. and treated tens thousands tumor patients. In the field of noninvasive ultrasound treating tumor technique China has continually kept the leading position in the world.

Objective To observe the response and relationship between astrocytes and neurons to hypotension rats. Methods Transient hypotension animal models were induced by injecting sodium nitroprusside. The expression, distribution and relationship pattern of Fos-、GFAP- or TH- positive reaction in rat brain were studied with a triple method combining anti\|GFAP, Fos and TH immunohistochemical staining. Results Fos and GFAP positive staining appeared in some brain regions related with blood pressure regulation. The distribution of GFAP\|positive astrocytes was similar to that of Fos\|positive neurons. Fos\|and GFAP\|positive neurons exhibited clear character of nuclei and subnuclei distribution. Many FOs and TH single labeled neurons, or Fos and TH double labelled neurons in medulla oblongata and locus coeruleus arounded by GFAP positive processes were found and formed three kinds of complex\|like structures. Conclusion\ The present results indicated that the astrocytes were sensentive to the changes of blood pressure. The distribution of astrocytes had the specificity of functional location. We suggestal that the astrocytes and neurons might be involved together in information precessing within brain.\;[

Objective To observe the treatment effect of Shah Mette Lo/fluticasone inhalation(Seretide)for stable stage of chronic obstructive pulmonary disease (COPD).Methods 50 patients with COPD were randomly divided into treatment group and control group.The treatment group was given Seretide (specifications of 250μg)1 -2 ceiling/time,2 times/day,after 24 weeks of treatment,the control group was given 2mg of regular salbutamol com-bined with budesonide 1mg atomization inhalation,2 times daily.The clinical symptoms were compared before and aftertreatment.Results In the treatment group,acute seizure frequency was significantly reduced,cough,wheezing singing decreased or disappeared,self -care ability improved,the control group had no obvious change.The control group:before treatment FEV1 (1.1 ±0.4)L;FEV1 % predicted value(22.5 ±5.1 )%;FEV1 /FVC%:(25.3 ±5.8)%;after treatment FEV1 (1.5 ±0.7)L;FEV1 % predicted value(29.4 ±6.2)%;FEV1 /FVC%:(32.8 ±6.6)%.The treatment group:before treatment FEV1 (1.1 ±0.6)L;FEV1 % predicted value (24.5 ±5.6)%;FEV1 /FVC%:(26.7 ±6.6)%;after treatment FEV1 (1.7 ±0.6)L;FEV1 % predicted value(33.4 ±7.8)%;FEV1 /FVC%:(37.8 ± 8.6)%.Conclusion In patients with stable COPD inhaled Seretide treatment can significantly improve lung func-tion,and it is better than sardine an alcohol combined with budesonide inhalation therapy.
