Purpose:To study the value of high frequency color doppler ultrasound diagnosis for breast intraductal papilloma.Methods:50 patients with breast intraductal papilloma,all confirmed by surgical and pathology,and examined by ultrasound before surgery,all had symptoms of excreting blood or liquid from nipple or palpable mass. The probe were placed on the surface of the breast to scan radially from nipple,after finding the enlarged duct,try to detect the neoplasm in it carefully. The two dimensional images were observed and the color Doppler flow codes were detected.Results:The detection rate and the diagnostic accuracy rate of breast intraductal papilloma by ultrasound are 62.0% and 38.0% respectively,ultrasonography is better than mammography and near infrared light scanning.The images were divided into four types:one type of no unusual finding(7 cases),one type of finding both the enlarged duct and the tumor(19 cases),one type of finding the enlarged duct only(12 cases),one type of finding the tumor only(12 cases),the images of the type of finding both the enlarged duct and the tumor are typical. The detection rate of flow by color doppler ultrasound is low(5/50).Conclusions:The high frequency color doppler ultrasound is valuable in diagnosis of breast intraductal papilloma,and the special symptom ,the accurate detection method and the typical images are the key of ultrasound diagnosis.

Objective To assess the effect of iDose4 in image quality and radiation dosage in CT angiography of craniocervical arteries.Methods Imaging data of 50 patients with 256-slice spiral CT angiography of craniocervical arteries were randomly divided into two groups:(A) 120 kV,250 mAs (25 patients),(B) iDose4 100 kV,180 mAs (25 patients).Dose length product (DLP) of the two groups were compared.Objective image noise was compared by two blinded readers,t test and nonparametric tests were used for statistical analysis.Results The overall image quality score of group A (3 points =1 patient,4 points =6 patients and 5 points =18 patients) and group B (4 points =5 patients and 5 points =20 patients) were shown.The image noise of group A (1 point =1 patient,2 points =5 patients and3 points =19 patients) and group B (2 points =4 patients,3 points =21 patients) were also evaluated.There was no statistical difference in revealing rate of image quality scores and objective noise between the two groups (Z =-0.334,-0.218,P ＞ 0.05).The estimated effective radiation dose was reduced by 56％ in group B than in group A.DLP was significantly lower in group B [(642.4 ±36.6) mGy · cm]than in group A [(1462.1 ± 64.3) mGy · cm].Conclusion Low dose contrast medium of CT angiography can display craniocervical arteries and the intracranial arteries very well with high image quality.

Objective To investigate the inhibition mechanism of tetramethylpyrazine combined with cisplatin on angiogenesis in Lewis lung cancer mice and to observe the mechanism of Arresten on angiogenesis in lung cancer. Methods The model of Lewis lung adenocarcinoma mouse xenograft was established in this work, and 40 mice were randomly divided into 4 groups: 0.9% sodium chloride solution group(NS group), tetramethylpyrazine group(TMP group), cisplatin group(DDP group), tetramethylpyrazine plus cisplatin group(TMP + DDP group), 10 mice in each group.Mice in NS group were given 0.2 mL of 0.9% sodium chloride solution, mice in DDP group were given 0.2 mL of 2 mg.kg-1 of cisplatin, mice in TMP group were given 0.2 mL of 100 mg.kg-1 of tetramethylpyrazine, mice in TMP+DDP group were given 2 mg.kg-1 of cisplatin and 100 mg.kg-1 of tetramethylpyrazine, each 0.1 mL .Tumor size was measured every day to calculate the tumor volume.The mice were sacrificed to stripp the subcutaneous tumor after continuous medication. The expressions of Arresten, integrin α1β1 and VEGF were determinated by immunhistochemistry and Western blotting. Results The tumor growth of NS group was the fastest and TMP+DDP group was the slowest. Compared with NS group, the expression of Arresten in the other three groups was increased( P<0.01) , and the TMP+DDP group exhibited the highest expression;at the same time, integrin α1β1 , VEGF in the other three groups was decreased(P<0.01), and the TMP+DDP group exhibited the lowest expression.The expression of integrinα1β1 and VEGF was negatively related to Arresten, and the expression of integrin α1β1 was positively correlated with VEGF. Conclusion TMP can inhibited the growth of Lewis lung carcinoma and angiogenesis. Moreover, in combination with cisplatin, TMP can also improved the effect of chemotherapy and then the survival state of mice. The mechanism of action, which TMP suppress tumor angiogenesis may be through improving Arresten and inhibiting integrin α1β1 and VEGF. And the action mechanism of Arresten may be implemented by inhibiting the expression of VEGF by incorporation with integrinα1β1 or by itself to inhibit the expression of VEGF.
