Objective To explore the value of ~(18)F 2-deoxy-2-fluoro-d-glucose(~(18)F-FDG)positron e-mission tomography (PET)/computed tomographic (CT) imaging and CT perfusion in evaluating metabolic and blood flow characteristics in breast cancer.Methods 32 women with untreated breast masses were both ex-amined with ~(18)F-FDG PET/CT and CT perfusion at the same day.All the lesions were confirmed histopothologi-cally by surgery or biopsy.The PET/CT images were analyzed semi-quantitatively.CT perfusion images were analyzed using the GE perfusion 3 soft package.The findings of two modalities above were commed with patho-logical diagnosis.Results There were significant differences between standardized uptake values (SUVs) of ~(18)F-FDG of benign tumors and breast cancer (Wilcoxon test:P=0.000 3,T=15.000,u=3.433,C=1).Differ-ences of SUVs between the center and periphery of breast Inasses were also significant.In addition.the SUVs were related to the pathological type and the grading of tumors.In the CT perfnsion,the differences of perfusion including bloodflow (BF),blood volume(BV)and permeability surface area product (PS) values between tumor and normal breast tissue were statistically significant(t=8.065,P<0.000 1;t=2.769 1,P=0.011 5;T~+=253.000 0,T~- =0.000 0,P<0.000 1)respectively.The differences of BF,BV and PS values between pe-ripheral zone and central portions of tumor were also statistically significant (t=8.015 8,P<0.000 1;t=2.243 4,P=O.017 9;t=3.485 7,P=0.002 2),respectively.Conclusion ~(18)F-FDG PET/CT imaging and CT peffusion reveal the metabolic and blood flow characteristics,and reflect biological behavior of breast tumor indirectly and have important value for the diagnosis and prognosis of breast cancer.

Objective To evaluate the hemodynamic changes and vascular complications after pediatric living donor liver transplantation (LDLT).Methods The hemodynamic changes of the portal vein,the hepatic artery and the left hepatic vein of the 34 cases were evaluated by color Doppler ultrasound during 2 months after LDLT.The vascular complications after LDLT were also evaluated.Results Of the 34 cases,vascular complications occurred in 5 cases.One day after LDLT,the max velocity of portal vein was (53.97 ± 21.44) cm/s,the peak systolic velocity of hepatic artery was (52.88 ± 17.87) cm/s,the resistance index was 0.73 ± 0.09,the max velocity of left hepatic vein was (40.53 ± 25.07) cm/s.The parameters of the hemodynamics had no significant difference between 1day and 1 week after LDLT (P＞0.05).The max velocity of portal vein was decreased after 2 weeks (P＜0.05).After 2 months,the max velocity of portal vein and the peak systolic velocity were decreased (P＜0.01 and P＜0.05) compared to 1 day.Vascular thrombosis was found in 5 recipients and all occurred in the first week after LDLT.Hepatic artery thrombosis (HAT) occurred in 3 (8.8 %) cases,portal vein thrombosis (PVT) in 2 (5.9 %).Among the 5 cases,3 were died.Conclusion The max velocity of portal vein and the peak systolic velocity of hepatic artery were decreased gradually after LDLT.The vascular complications occurred in the early stage and had a relatively high rate.Doppler examination should be performed once every day within 7 post-transplant days.

To investigate the association of serum 3-nitrotyrosine ( 3-NT ) with carotid atherosclerosis in newly diagnosed type 2 diabetic patients. 96 patients with newly diagnosed type 2 diabetes mellitus treated in the department of endocrinology of Tangshan Gongren Hospital were recruited, and were divided into two groups depending on their carotid atherosclerosis status as carotid atherosclerosis group ( CAS group, n = 54 ) and non-carotid atherosclerosis group ( NCAS group, n=42); while 51 healthy subjects without type 2 diabetes mellitus from the medical examination center were recruited as normal control group ( NC group, n=51) . Demographic and clinical data of all subjects were collected. Serum 3-NT levels were measured by Enzyme-Linked Immunosorbent Assay ( ELISA) . ( 1) The levels of 3-NT in CAS group and NCAS group were all higher than those in NC group, and the level of 3-NT in CAS group was higher than that in NCAS group (all P<0.05);(2) In type 2 diabetic patients, 3-NT was positively correlated with HbA1C and low density lipoprotein-cholesterol ( both P<0. 05); ( 3) Logistic regression analysis showed that age (OR=1.271, P=0.023), HbA1C(OR=1.812, P=0.005) , Hcy (OR=1.194, P=0.019), and 3-NT (OR=1.593, P=0.011) were risk factors of CAS in type 2 diabetic patients. Serum 3-NT was closely correlated with carotid atherosclerosis in newly diagnosed type 2 diabetic patients, suggesting that serum 3-NT may be involved in the carotid atherosclerosis of newly diagnosed type 2 diabetic patients.
