Objective To explore the role of rescue video logical slice and interactive analysis in the continuous improvement of quality of emergency care of multiple injury. Methods To establish a management team for the rescue video interactive analysis. From May, 2015 to April, 2016, every Wednesday from 8:00-11:00 am, the data of multi-injury patients registered in our management software of critical emergency cases were selected. A typical case study of the rescue video logical slices were processed through sorting the video cases in the video surveillance system installed in the emergency room. According to the characteristics of diagnosis and treatment of multiple injury, the evaluation indexes of nursing quality in emergency treatment of multiple injury were formulated and video data was analyzed interactively by using the failure mode analysis and root cause analysis. Based on the above analyzed results, the quality of emergency care of Multiple Injury was controlled and improved. Before and after performing the rescue video logic slices and interactive analysis management, the examined results of multiple injury first-aid nursing quality index, as well as the rate of patients satisfaction and nursing defects were compared. Results Before the implementation of the above method, the time of emergency treatment for multiple injury, the rate of patients with successful rescue, the rate of patient transport defect and the rate of missing items in the rescue unit were respectively as follows:(87.1±7.4)min, 90.77%(59/65), 30.77%(20/65), 12.31%(8/65),whereas after the implementation, the relevant data were (57.5 ± 5.2) min, 100.00%(68/68), 10.29%(7/68), 2.94%(2/68). The comparative difference before and after the implementation was statistically significant (t=26.84, χ2=2.15, 2.72, 1.72, all P < 0.05). Besides, the satisfaction with the various evaluations of patients′ family members was increased and the differences were statistically significant (χ2=15.45-23.21, P<0.05). Conclusions The introduction of rescue video slices and interactive analysis can effectively reduce the patient′s rescue time, improve the success rate of patients rescues, decrease the rate of patient transport defect and missing items in the rescue unit, effectively control the quality of links, improve the management efficiency, and thus realize the standardized management under normal working condition.

Objective To forward the concept of solution space of pharmacokinetics for studying radiophannaceutical distributions in animal models. Methods On the basis of special solutions of differential equations of pharmacokinetics, the solution space was established using the characteristics of linearly independent particular solutions and used to express the pharmacokinetics of pharmaceuticals in vivo. 0. 2 ml (7.4 MBq) 2β-carbomethoxy-3β- (4-corophenyl)-8-(2-18F-fluoroethyl) nortropane (18F-FECNT) was injected through tail vein into normal mice. The mice were sacrificed by decapitation at 5, 15, 30, 60, 120 and 180 min post-injection. Brain tissues were removed and weighed, and radioactivity was counted with the γ-counter. The solution space theory was used to study pharmacokinetics of 18F-FECNT in brain tissues of mice. Results The result showed that all solutions of pharmacokinetics models, based on differential equations, were included in the solution space. The solution of any organ or tissue could be linearly expressed by bases of the solution space. When the dimension number of the solution space was no more than 3, the solution could be directly expressed with coordinate picture. By this rule in our theory, the quantity of 18F-FECNT in brain tissues of mice changed with time, which was accorded with the experiment. The coordinates of striatum, frontal cortex, temporal cortex, occipital cortex, parietal cortex, hippocampus and cerebellum in the solution space were ( 10.13, 1.49), (4.27, 0. 84), (4.48, 0.81 ), (2.89, 0.98), (3.65, 0. 83),(3.55, 0. 98) and (2.03, 1.25 ), respectively. Conclusion The theory of solution space could be used to study pharmacokinetics of 18 F-FECNT in mice brain.

Objective To evaluate left ventricular systolic synchronicity in patients with dilated cardiomyopathy by V-plane imaging and compare with clinical commonly used tissue Doppler imaging (TDI),evaluate the relevance and consistency between these two parameters.Methods 20 patients diagnosed with DCM and 20 healthy controls were enrolled,2D images,V-plane imaging and TDI waveform were acquired.Time to peak velocity of left ventricular 12 segments were measured by TDI and the standard deviation (TDI_SD) were calculated.Displacement time to peak were measured by V-plane and the standard deviation (V-plane_SD) were calculated.Results Compared with control group,TDI_SD and V-plane_SD increased significantly (P ＜ 0.01),TDI time to peak increased and V-plane time to peak decreased significantly(P ＜0.01).In the two group,12 segment time to peak measured by V-plane were significantly higher than TDI(P ＜ 0.01).There was a significant correlation between TDI_SD and V-plane_SD (r =0.925,P ＜0.001).Bland-Altman plot showed that 95％ plots of ratio of TDI_SD and V-plane_SD were among limits of agreement,which was (0.50,1.36).Conclusions Left ventricular systolic synchronicity in DCM patients can be observed by V-plane imaging.V-plane has significant relevance and consistency with TDI,and can overcome the limitations of TDI that 12 segments can not be displayed in the same cardiac cycle.

Objective To investigate the differential value of contrast-enhanced ultrasonography (CEUS) and time-intensity curves(TIC) in diagnosing testicular and epididymal mass lesions.Methods CEUS via intravenous bolus injection of SonoVue and TIC were performed for quantitative analysis of testicular and epididymal mass lesions.Forty-one patients with 42 testicular and epididymal mass lesions and 26 normal testicles were examined with CUES,the perfusion progress were recorded dynamically,which findings were compared with surgery.Results Twenty-three (54.76％) malignant masses displayed enhanced pattern as evenly enhanced,fast-in and fast-out (8.7％),evenly enhanced,fast-in and slow-out (65.2 ％ ),unevenly enhanced,fast-in and slow-out (26.1％ ).Ninteen (45.24 ％ ) benign masses revealed enhanced pattern as unevenly enhanced,fast-in and slow-out ( 10.5 ％),evenly enhanced,slow-in and slowout ( 10.5 ％ ),unevenly enhanced,slow-in and slow-out ( 36.9 ％ ),without enhancement ( 42.1％ ).There was statistical difference of peak intensity,time to peak and areas among malignant group,benign group and normal group ( P ＜ 0.05).Conclusions CEUS combined with TIC could provide differential diagnostic value for testicular and epididymal mass lesions.

OBJECTIVETo investigate the neuro-immune regulatory mechanism of Heart Benefiting recipe (HBR), an effective recipe for treatment of Alzheimer's disease (AD).

METHODSUsing immunohistochemical and RT-PCR methods, the neuro-immunological pathological changes in the AD rat model induced by beta-amyloid protein (A beta1-40) via lateral cerebral ventricle injection, including mainly the glial fibrillary acidic protein expression and inflammatory cytokines IL-1beta, IL-6mRNA and beta-amyloid protein precursor (APPmRNA) gene expression were studied. And the effects of HBR on these parameters were observed.

RESULTSDeposition of A beta in cerebral tissue could induce activation of stellate glial cells and abnormal increased levels of inflammatory cytokines (IL-1beta and IL-6mRNA), also the elevation of APPmRNA level. HBR could effectively control the above-mentioned pathological changes.

CONCLUSIONHBR could effectively control the inflammation and the A beta immune cascade reaction in brain of AD patients, it is one of the important therapeutic mechanisms of the recipe.
