Objective:To investigate the comparison of diagnostic value between multi-slice spiral CT (MSCT) and MR pulmonary angiographies in the diagnosis of acute pulmonary embolism.Methods: 86 patients with acute pulmonary embolism who underwent imaging examination were randomly divided into control group (43 cases) and observation group (43 cases) according to random number table method. The patients in the control group were analyzed with MSCT for enhanced scan under pulmonary angiography. The patients in the observation group were analyzed with MR for pulmonary artery imaging and pulmonary embolism. These results were compared depended on above data.Results: The differences of sensitivity and Youden index between control group and observation group were statistically significant (x2=10.052,x2=10.052,P<0.05), and the sensitivity of observation group was higher than that of control group, and both the diagnostic specificity of the two groups were 100%. For embolism of different part, the accuracy of observation group was higher than that of control group. And for the comparison of left multiple between the two groups, the difference were significant (x2=4.168,P<0.05). While for the comparisons of single, bilateral and multiple for right side, the differences between the two groups were no significant (x2=2.355, x2=0.917,x2=2.912,P>0.05). For the diagnosis of various indirect symptom, the accuracy of observation group was higher than control group. For the comparison of diagnostic accuracy of pulmonary segments infarct between the two groups, the difference of them was significant (x2=5.630,P<0.05). While the comparisons of pericardial effusion, pleural effusion and pulmonary artery hypertension, the differences of them between the two groups were no significant (x2=3.214,x2=3.733,x2=3.281;P>0.05).Conclusion: For patients with acute pulmonary embolism, the diagnosis by using MR imaging technology has series advantages, such as convenient operation and higher diagnostic accuracy, and it can accurately determine the severe degree of the disease.

It is very difficult for stroke patients to complete the action of squatting-standing because their equilibrium function ability has been seriously declined. It was necessary, therefore, to do a deep research on the action of human squatting-standing and to set up an accurate model and simulation. In our modeling research, the movements of upper limbs and head was neglected, and a seven-segment model was developed to establish the coordinate system of human squatting-standing action. It calculated the knee joint moment and hip joint moment during squatting and standing by utilizing Lagrange method, and then simulated this mathematical model by utilizing Matlab. Geometric model of human squatting-standing was developed and simulated in ADAMS which proved that the established Lagrange model was reasonable. It would also provide significant theoretical references for further study and development of squatting-standing rehabilitation training equipment.

Objective To investigate correlation between the expression of TIG1 and the prognostic significance in acute leukemia (AL).Methods The TIG1 expression level of 75 AL and 20 normal control (NC) were measured by Real-Time Quantitative PCR(RT-QT-PCR).Results TIG1 gene expressed at a higher level in NC(0.0609±0.0281 ) than that in de novo AL(0.0057±0.0035)(U=-6.321,P=0.000).The expression of TIG1 in complete remission patients(AL-CR)(0.0409±0.0244)were lower than that in NC too(U=-2.582,P=0.01).The expression of TIG1 in AL-CR patients (83.3 ％) were higher than that in de novo AL (53.1％)(U=-6.366,P=0.000).In AL patients,the CR rate of high TIG1 level cases were higher than that in low level cases (x2=4.563,P=0.033).Conclusions Reduced expression of TIG1 may play an important role in the pathogenesis of AL.TIG1 can serve as a marker of poor prognosis in AL.
