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.

结果200例患者均成功完成了适应性前瞻性心电门控双源CT冠状动脉血管成像；30例同期行SCAG检查的患者，A组17例：HR≤75 bpm，可评价冠状动脉节段255个，70个冠状动脉节段有105处不同程度的狭窄，95处狭窄程度与金标准SCAG相符，其阳性诊断准确率为90.48%；2种方法的诊断结果得到了较高的一致性(Kappa值=0.853)。B组13例；HR≥91 bpm，可评价冠状动脉节段195个，57个冠状动脉节段有73处不同程度的狭窄，65处狭窄程度与SCAG相符，其阳性诊断准确率为89.04%；2种方法的诊断结果得到了较高的一致性(Kappa值=0.835)。2个心率组间的诊断准确率无明显统计学差异(x~2=0.098，p＞0.05)。30例患者的平均有效辐射剂量为3.67±0.43 mSv结论适应性前瞻性心电门控双源CT冠状动脉成像是一种有效减低辐射剂量的扫描方式，其诊断准确率与金标准SCAG相比得到较高的一致性，且高、低2个心率组间诊断准确率无明显统计学差异。

In order to study function and molecular polymorphism of classⅡB gene in fish, we have isolated cDNAs encoding classⅡB from spleen cDNA library of red sea bream by using EST sequencing, and examined genomic organization, molecular polymorphism and expression of red sea bream classⅡB gene.

在所测序的11个不同的阳性克隆中，有4个不同的cDNA序列被鉴定出。另外，利用rsbMHC2b3'UTRN和rsbMHC2b3'UTRC为引物，扩增同一真鲷个体的3'UTR，有12个阳性克隆被测序，测序结果中有2个不同的序列被鉴定出，表明MHCⅡB基因至少存在两种不同的位点。
