Objective To evaluate the low-dose dual-source whole-body CT angiography in assessing the arteries of Takayasu’s arteritis (TA).Methods Low-dose whole-body CT angiography(CTA)was performed in 57 consecutive patients with suspected TA. The scanning parameters were performed with tube voltage 80 kV and attenuation-based tube current modulation with a referenced tube current at 300 mAs.The volume CT dose index (CTDIvol)and dose-length product (DLP)were obtained for all scans.Subjec-tive and objective image quality of different arteries were assessed in seven anatomic territories,including intracranial,cervical,tho-racic,abdominal,upper extremity,thigh and shank.In addition,CT findings of whole-body arteries were recorded.Results Forty out of fifty-seven patients with definite diagnosis of TA enrolled in this study.Mean CTDIvol and DLP for all patients were (2.5± 0.9)mGy and (403.7±91.4)mGy·cm,respectively.The scoring order of subjective and objective iamge quality was neck,chest, abdomen,thigh,upper extremity,head and shank.5.9% of intracranial arteries,3.3% of lower extremity arteries and 0.5% of upper extremity arteries were extra detected.Conclusion The extra CT findings of intracranial,lower extremity and upper extremity arter-ies provides a more comprehensive evaluation of whole-body arteries involvement.

Objective:To investigate lesion size caused by channel radiofrequency volumetric reduction of por-cine tongue base in vitro using the technique of three-dimensional reconstruction. And to evaluate safety about channel radiofrequency volumetric reduction of tongue base. Method: Eighteen fresh porcine tongues were randomly separated into six groups,and each group had three ones. The tongue bases were designed six points according to description of Powell. Tongues base were acted on 10 s and 6 level by Coblation radiofrequency system and were cut into serial freezing histological sections. These segments were sectioned at 20 μm on the injury lesion and stained with H & E. Collected 2D digital imagine of order histological sections, drawn and cut apart part of the le-sion of these sections. Images were procesed IPS and were taken three-dimensional reconstruction and statistics an-alyzes with SPSS10. 0.

Objective To estimate the application value of dual-source CT on preoperational evaluating new type of three branches aortic arch covered stent graft implantation on DeBakey type I aortic dissection.Methods 20 cases with DeBakey type I aortic dissec-tion prepared to performe three branches aortic arch covered stent graft implantation were reviewed,and their CT findings were ana-lyzed in order to evaluate the guiding value for operation.Results The location and size of entries were determined and the diameter of aortic arch and three branchesas well as the intervals of three branches were also measured by dual-source CT.Furthermore, blood-supply for main vessel and complications related with covered stent were further analyzed prior to operation.The surgical pro-tocols were designed according to preoperational CT findings.Among all cases,13 cases were fit for new type of three branches aor-tic arch covered stent graft implantation.While the rest cases (N=7)were adopted other operations due to non-fitted indications. Conclusion Dual-source CT is of significance for preoperational evaluating new type of three branches aortic arch covered stent graft implantation on DeBakey type I aortic dissection.

OBJECTIVE:To compare the composition changes of Aurantii fructus before and after fermentation processing and optimize its fermentation processing technology. METHODS:UPLC was conducted to compare the raw and fermentation processed products of same batch of Aurantii fructus,and ensure the chromatographic peaks after fermentation processing. Using peak areas of 4 chromatographic peaks and mildew characteristics of samples as index,fermentation temperature,humidity and time as factor, L9(34)orthogonal test was designed to optimize the fermentation processing technology,and verified it. RESULTS:After fermenta-tion processing,Aurantii fructus obviously showed 2 new monosaccharide glycosides components;the optimized fermentation tech-nology was as follows as fermentation temperature of 30 ℃,humidity of 70% and time of 7 d;verification test results showed RSD of each indicator of decoction pieces prepared by optimized fermentation technology in 3 tests were lower than 2.0%(n=3). CONCLUSIONS:Fermentation processing may lead obvious chemical composition changes in Aurantii fructus;the optimized fer-mentation processing technology can increase the contents of characteristic peaks.

Objective To prospectively evaluate the effects of heart rate and heart-rate variability on dual-source computed tomographic coronary image quality in patients with high heart rates,and to determine retrospectively the accuracy of dualsource computed tomographic diagnosis of coronary artery stenosis in the same patients.Methods The image quality and diagnostic accuracy were compared between the normal group of 40 patients whose heart rates exceeded 70 beats/min and the control group of 40 patients whose heart rates were 70 beats/min or slower.Results No statistically significant differences between the groups were found in diagnostic-image quality scores of total segments or of any coronary artery,nor were any significant differences found between the groups in the accurate diagnosis of angiographically significant stenosis.Calcification was the chief factor that affected diagnostic accuracy.In high -heart -rate patients,heart -rate variability was significantly related to the diagnostic image quality of all segments(P=0.001) and of the left circumflex coronary artery(P=0.016).Heart-rate variability more than 5 beats/min most strongly contributed to an inability to evaluate segments in both groups.When heart rates rose,the optimal reconstruction window shifted from diastole to systole.Conclusion The image quality of dual -source computed tomographic coronary angiography at high heart rates enables sufficient diagnosis of stenosis,although variability of heart rates significantly deteriorates image quality.
