Objective To analyze the application of MSCT in A.C.T. Methods MSCT and CR examination results of 41 A.C.T cases were compared and analyzed by 3 doctors. Results Compared with plain flim,MSCT markly increased the fracture detection rate. Conclusion MSCT is precise and safe in the diagnosis of A.C.T.

Starting from present existent problems,it puts forwards that TCM case teaching can deepen the understanding to TCM theory,and to some extent improve shortcoming in clinic,helpful to training of TCM thought model of collegial students.

A novel strategy employing dendrimer to multi-label the template molecule to improve the sensitivity of molecularly imprinted electrochemical sensor was proposed. The determination relies on a competition reaction between poly ( diethylene-triaminepenta-acetic acid )-glycol ester ( PDTPA )-ferrocene-carboxylic acid ( FcA ) labeled gibberellins acid 3 ( GA3 ) and GA3 in the sample. Since one cavity corresponds with multiple FcA, instead of only one FcA, the intensity of the detecting signal was greatly enhanced, so was the sensitivity of the sensor. Experimental results showed that the molecularly imprinted electrochemical sensor was sensitive to GA3 detection at a concentration from 2. 0í10-9 to 1. 0í10-7 mol/L, with a detection limit of 9. 3í10-10 mol/L. In addition, the sensor had good reproducibility and its feasibility was verified in the analysis of series of real beer samples.

Shortages in the fostering of medical humanistic spirits for students majoring medical science of law in medical colleges and universities were discussed from the perspectives of concept establishment,curriculum,clinical teaching and teaching staff.The fostering of medical humanistic spirits for students should be enhanced to achieve the balance between medical humanity and legal professionalism.

The prevalence of obstructive pulmonary disease (COPD) and chronic heart failure (CHF) increased gradually with age. The coexistence of COPD and CHF was very common but often neglected. To avoid overlooking COPD in patients with known CHF, pulmonary function tests should be routinely obtained. Likewise, to avoid overlooking CHF in patients with known COPD, left ventricular function should be routinely assessed. Plasma brain natriuretic peptide was a useful index to differentiate COPD exacerbation from CHF decompensation in patients presenting with acute dyspnea. Skeletal muscle metabolic alterations and its atrophy were the common mechanisms which resulting in deterioration of function capacity in elderly patients with CHF and COPD. Contrary to the conventional belief, long-term beta adrenergic blockers should be given to elderly patients with CHF and COPD. Exercise training reverses rapidly progress of skeletal muscle metabolic alterations and atrophy and promotes independence and life quality in elderly patients.

OBJECTIVE:To investigate the effects of early before PCI and immediate application of tirofiban on coronary blood flow and myocardial perfusion in patients with high risk acute coronary syndrome (ACS). METHODS:100 high risk ACS patients were randomly divided into observation group and control group,with 50 cases in each group. Two groups were given tiro-fiban;observation group was given medicine 10 μg/kg within 3 min,4-6 h before PCI,with the velocity of 0.15 μg/(kg·min)till 24 h after PCI. Control group was given medicine at the beginning of PCI,route of administration was same as observation group. The incidence of TIMI blood flow grading,TIMI myocardial perfusion grade (TMPG),cTn Ⅰ,PAR and main adverse cardiac events(MACE)were compared between 2 groups before and after treatment. RESULTS:After operation,the patients of 2-3 grade TIMI blood flow and 2-3 grade TMPG in 2 groups were significantly more than before;the patients of 2-3 grade TMPG in observa-tion group was significantly more than in control group,with statistical significance(P<0.05). After treatment,cTn Ⅰof 2 groups were significantly increased,while PAR were significantly decreased,with statistical significance compared to before operation (P<0.05);but there was no difference between 2 groups (P>0.05). There was no statistical significance in the incidence of MACE between observation group(8.0%)and control group(16.0%)(P>0.05). CONCLUSIONS:Early application of tirofiban before PCI can effectively improve coronary blood flow and myocardial blood supply in high risk ACS patients.

Objective To explore the influence of ROI size on the diagnostic performance of shear wave elstography (SWE) of breast masses.Methods A total of 225 consecutive patients with 239 solid breast masses underwent SWE before surgery,and then quantitative SWE parameters,including the maximum stiffness (Emax),mean stiffness (Emean),ratio of stiffness of the mass to stiffness of surrounding fat (Eratio) and standard deviation (SD),were measured by two methods,one method was using larger ROI to include the largest part of a mass,and the other was placing fixed ROI=2 mm over the stiffest part of the lesion to measure.The diagnostic performance of the two methods were evaluated by ROC curve,and the cut-off value,sensitivity and specificity of each SWE parameter were obtained.Results There were no statistically significant differences between the performance of Emax,Emean and SD from the two different methods (all P＞ 0.05),the performance of Eratio of the two methods showed significant difference (P=0.046).The significantly higher specificity of Emax and Emean in the larger ROI were found,and the significantly higher sensitivity of SD and Eratio in the ROI=2 mm was found.Furthermore,the diagnostic performance of combination of SWE and BI-RADS were not greatly affected by the ROI size,the difference had no statistical significance (all P＞0.05).Conclusion The ROI size only affects the diagnostic performance of Eratio,and donot affect the diagnostic performance of the quantitative SWE parameters (Emax,Emean,SD) and combination of SWE and BI-RADS.

12 patients with inconsistent growth of twins were involved.The acoustic features were analyzed,inclu-ding 2D and Doppler images.The differential diagnosis was verified during follow-up exam in some patients.8 cases were diagnosed with sIUGR by ultrasonography,meanwhile 3 were diagnosed with TTTS.The rest 1 case could not be etiologically diagnosed due to the bad image conditions.We can differentiate the two diseases by evaluating the umbilical cord insertion,the amiotic fluid and the hemodynamics of the other twin.Ultrasonography is helpful in the differential diagnosis for TTTS and sIUGR.

Compensatory of colateral circulation is a key factor affecting the outcome in patients w ith acute ischemic stroke. This article review s the development of colateral circulation and its affecting factors, and the predictive value of colateral circulation for the outcome in patients w ith acute ischemic stroke.
