Objective To investigate the value of quantitative parameters of CEUS in predicting the effect of ultrasound ablation of uterine fibroids.Methods Sixty-three patients with uterine fibroids underwent CEUS before operation.The software of gray level measurement in JC HIFU system was used to obtain quantitative parameters of uterine fibroids perfusion.According to postoperative enhanced MR examination,the results were divided into satisfactory group (ablation rate≥70 ％) and partial ablation group (ablation rate＜ 70 ％).CEUS parameters of two groups were compared,and the correlation between parameters and ablation rate were analyzed.The predictive value was evaluated by ROC curve.Results There were significant differences in the time of arrival (AT),time to peak (TTP),enhancement time (ET),enhancement intensity (EI) and enhancement rate (ER) between the two groups (all P＜0.01).The AT,TTP and ET were positively correlated with the ablation rate (all P＜0.01),and the EI and ER were negatively correlated with the ablation rate (both P＜0.001).The area under the curve (AUC) of AT,TTP,ET,EI,ER were all greater than 0.7,among which ER had the highest predictive value (AUC-0.935).Using ER=5.23 as the cut-off point,the sensitivity of predicting ablation effect was 80.0％,specificity was 95.8％.Conclusion There is a certain correlation between the ultrasound ablation effect of uterine fibroids and the quantitative parameters of CEUS.ER can be used as a good predictor of ablation effect.

This dissertation is to determine the biopotency of hemostat which processed in different places by establishing a bioassay method of Bletillae Rhizoma based on the thrombin time. Contrast test is the main methodology. Specifically, the reference substance of Bletillae Rhizoma is determined by comparing with the control substance of vitamin K1 using thrombin time, which is calibrated the Bletillae Rhizoma. The hemostatic biopotency is calculated by using the method of "parallel line assay method based on quantitative responses" (3.3) from different processed products. It indicates that there is a strong linear correlation between Bletillae Rhizoma and control drugs (Y = 66.332-23.913X, R2 = 0.995 3). The hemostatic biopotency of Bletillae Rhizoma from different processed products ranged between 821.93-1 187.53 U x g(-1) shown in the paper, and all of them can meet the requirements of the test. The methodology has an appropriate instrument precision (RSD 3.8%), intermediate precision (RSD 4.6%), repeatability (RSD 3.2%) and stability (RSD 3.7%). Therefore, it can be turned out that the methodology which established in the dissertation is good at determinating the hemostatic biopotency of Bletillae Rhizoma and it is reliable, simple and repeatable.

Objective: To investigate the short term clinical efifcacy of endovascular repair for complicated acute type Stanford B aortic dissection.
Methods: To retrospectively analyze the clinical data of 36 patients with complicated acute type Stanford B aortic dissection who received endovascular repair in our hospital from 2010-01 to 2014-06 including operational procedure and post-operative follow-up of CT angiography. There were 27 male and 9 female patients with the average age of 43.7 years (41-62) years.
Results: Successful operations were conducted in all 36 patients. 22 patients received endovascular repair combined with covering left subclavian artery (LSA),10 received endovascular repair combined with chimney technique, 2 received endovascular repair combined with vascular prosthesis bypass from left common carotid artery to LSA, 2 received endovascular repair combined with vascular prosthesis bypass from right common carotid artery to left common carotid artery, whose proximal parts were ligated. Viscera artery and lower extremity artery supply were restored gradually. No complication of endoleak occurred. There 30/36 (83.33%) patients were followed-up for 1 year, and 10 patients developed thrombus in full false lumen and 20 developed thrombus in partial false lumen after 1 year. Compared with pre-operative values, thoracic aortic true lumen volume increased in either thrombus in full false lumen (190 ± 68.7) ml vs, (125.3 ± 63.4) ml and thrombus in partial false lumen (166.2 ± 71.8) ml vs (110.1 ± 62.7) ml,P<0.001; thoracic aortic false lumen volume decreased (65.0 ± 67.4) ml vs (185.3 ± 66.6) ml and (132.3 ± 62.6) ml vs (224.5 ± 72.3) ml,P<0.001. Compared with pre-operative values, for patients with thrombus in full false lumen, the abdominal aortic true lumen volume increased (55.5 ± 12.4) ml vs (48.6 ± 12.2) ml,P<0.01; for patients with thrombus in partial false lumen, the abdominal aortic false lumen volume also increased (58.2 ± 21.5) ml vs (42.5 ± 18.5) ml,P<0.01.
Conclusion: For endovascular repair of complicated aortic dissection, covering LSA with chimney technique and hybrid operation of small incision could extend anchor zone and expand the range of endovascular repair which may improve the effect and reduce the complication for good short term effect.
