Accuracy between two groups was calculated byχ~2 test.Calculate the average effective radiation dose of the 30 patients.Results In group A,seventeen patients underwent both DSCT coronary angiography and SCAG,among 255 segments of 17 patients,105 lesion sites of 70 segments were diagnosed stenosis or obstruction,of them,95 lesion sites were confirmed by SCAG.The accuracy of DSCTCA was 90.48%.The agreement of two methods have a high agreement(Kappa =0.853).In group B,13 patients underwent both DSCT coronary angiography and SCAG,among 195 segments of 13 patients,73 lesion sites of 57 segments were diagnosed stenosis or obstruction, of them,65 lesion sites were confirmed by SCAG.The accuracy of DSCTCA was 89.04%.The agreement of two methods have a high agreement(Kappa =0.835). There was no significant difference(χ~2=0.098,p＞0.05) between the accuracy of two groups.The effective radiation dose of 30 patients was 3.67±0.43 mSv.Conclusion Compared with SCAG,prospectively ECG-gated transverse DSCT is a valuable examination to detect and diagnose coronary artery disease with a low dose coronary angiography.The accuracy of the DSCT is approximate to the SCAG.There was no significant difference between the accuracy of two groups.

In order to inquire the causes of occurrence of lipoid pneumonia in rat that were raised in standard SPF animal reproductive area, we used self-reproducing standard SPF rats, male 50 and female 50. All of the rats were divided into 10 groups, raised in standard Barrier system, and fed the standard diets imported from U.S.A.. All animals were divided into 4 stages to sacrifice. Autopsy, histopathological and blood biochemical examination were made at each stage. The results reveal that no lipoid pneumonia were found to occur in the 5, 10 and 26-week-old groups of male and female rats. 40% of male and 60% of female were found to occur slight focal lipoid pneumonia in the 52-week-old groups of rats.

So, the aromaticity of acenaphthenyl groups in C_2 gum should be the least. In order to explain the reason, quantum chemical calculation is utilized. The optimized geometrical structrures of condensed aromatics in C_1 gum, C_2 gum and C_3 gum are calculated at B3LYP/6-31G* levels. We find that some phenyl groups in acenaphthenyl groups are coplanar and have the largest conjugated structure.

为了解释其原因，我们利用量子力学方法进行了计算，研究了三种稠环基团在B3LYP／6-31G*基组水平下优化得到的几何结构，发现苊式多苯基苯基中的萘环和中间的苯环共面，电子离域性最大，而其他二者所有苯环都不共面，发生了明显地扭曲；同时，在优化几何结构的基础上，对三种化合物进行了前线分子轨道的分析，利用密度泛函理论方法(density function theory，DFT)计算了稠环基团的最高占有轨道和最低未占轨道之间的能量差，即能隙，发现C_2胶上苊式多苯基苯基的Eg最小，解释了C_2胶具有最好的辐射保护效果的原因。
