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.

OBJECTIVETo investigate the expressions of stromal cell-derived factor-1 (SDF-1) and CX chemokine receptor-4 (CXCR-4) in patients with hepatocellular carcinoma (HC) and liver cirrhosis.

METHODSPeripheral blood and/or ascites fluid were collected from 39 hepatocellular carcinoma patients, 16 patients with liver cirrhosis, 12 with hepatitis and 12 healthy donors. The SDF-1 expression was assayed by ELISA and CXCR-4 was measured by immunohistochemical methods.

RESULTSThe level of SDF-1 expression in the carcinoma patients was higher than that of the liver cirrhosis, hepatitis patients and healthy donors, but there was no significant difference between those of the healthy donors and hepatitis patients or liver cirrhosis patients. The levels of CXCR-4 expression were closely related to the tumor differentiation.

CONCLUSIONThe expression of SDF-1 in the peripheral blood and the CXCR4 expression in the HCC tissues of the HC patients may be regarded as markers of HC and they may have a positive relationship with the differentiation and metastasis of HC.

Objective To explore the relationship between therapeutic dosage of ultrasound ablation in treatment of uterine fibroids and imaging characteristics of bloody supply of uterine fibroids by color Doppler ultrasound imaging. Methods One hundred and forty-two patients with 168 fibroids were treated by ultrasound ablation. Before treatment, bloody supply of fibroids were classified into grade 0 -4 by ultrasonography. Three patients lost follow-up with contrast MRI exam within 1 month after treatment, so 165 fibroids were enrolled in this study. Bloody supplies were 9 fibroids in grade 0, 34 fibroids in grade 1, 35 fibroids in grade 2, 55 fibroids in grade 3 and 32 fibroids in grade 4. After 1 month treatment, the treated area without blood supply and ratio of ablation were measured by contrast MRI to evaluate the efficacy of thermal ablation and compare status of blood supple based different therapeutic dosage. According to International Reditherapy for Society ( SIR ) standard, adverse effect and score of pain were evaluated. Results ( 1) Ratio of ablation based; ratios of ablation were 79% in grade 0, 89% in grade 1, 92% in grade 2, 86% in grade 3, 71% in grade 4. It reached statistical difference when blood supply of grade 0 compared with those of grade 2 and 3 (P ＜ 0. 05 ) and blood supply of grade 4 compared with those of grade 1, 2, 3 ( P ＜ 0. 05). (2) Factor of energy efficiency:factor of energy efficiency were 13.19 J/mm3 in degree 0, 9. 54 J/mm3 in degree 1, 12. 91 J/mm3 in degree 2, 17. 83 J/mm3 in degree 3 and 28. 10 J/mm in degree 4. Factor of energy of ablation in degree 4 was significantly higher than those in degree 1, 2 and 3 blood supply (P ＜ 0. 05). It exhibit the positive relationship between blood supply and factor of energy of ablation ( r = 0. 354 ,P ＜ 0. 01). ( 3 ) Score of pain and adverse effect: nearly 85% ( 120/142 ) patients could tolerate this treatment very well. Those scores of pain were in range of 0 to 4. All patients did not extend their hospitalization and C to F of SIR standard was not recorded. Conclusion blood supply of myoma measured by ultrasound could predict dosage of ultrasound ablation, it could help select indicated well patients.
