Objective To analyze the MRI features of fibrocystic breast disease (FBD). Methods 39 patients with pathologically proven FBD were retrospectively reviewed. The imaging protocol consisted of pro-contrast imagings and bilateral breast volume im-aging for breast assessme NT(VIBRANT). MRI features were interpreted based on the morphologic and enhancement kinetic de-scriptors defined on ACR DIRADS-MRI lexicon. Results There were 3 types on ACR BI-RADS-MRI lexicon in FBD,including 13 focal mass-type showing malignant enhancement kinetic pattern mostly;15 cyst-type with non-enhancement or mild enhance-ment,of them,1 case with periductal mastiffs showing strong enhancement and rapid up-slope and wash-out mimicking a breast cancer. 6 non-mass type usually showing benign enhancement kinetic pattern. In 5 patients,MRI did not show definite abnormal evi-dence. Conclusion MRI is of significant value in diagnosing FBD.

Objective To study the practicality and repeatability of B-mode ultrasonography on diagnosis and score of carotid atherosclerosis. Methods Ninety-nine B-mode ultrasonography pictures of carotid atherosclerosis were obtained from field investigation. According to the established standard(normal scored as 0, other scored as 1 - 7 by the severity), the 99 pictures were diagnosed and scored once together by three trained inexperienced members of the research team. Ten days later, these pictures were diagnosed and scored respectively, by the three members.The diagnostic results were analyzed with statistical methods to test the feasibility and repeatability of this set of diagnostic and scoring system. Results The joint diagnostic results by the three group members were regard as standard with scores 0 in 27 cases, 1 in 27 cases, 2 in 10 cases, 3 in 4 cases, 4 in 13 cases, 5 in 8 cases, 6 in 6 cases, and 7 in 4 cases. Independent diagnostic results by member A was 0 in 29 cases, 1 in 24 cases, 2 in 11 cases, 3 in 2 cases, 4 in 12 cases, 5 in 11 cases, 6 in 6 cases, and 7 in 4 cases. Independent diagnostic results by member B was 0 in 29 cases, 1 in 22 cases, 2 in 14 cases, 3 in 4 cases, 4 in 13 cases, 5 in 5 cases, 6 in 8 cases, and 7 in 4 cases. Independent diagnostic results by member C was 0 in 28 cases, 1 in 25 cases, 2 in 8 cases, 3 in 5 cases, 4 in 14 cases, 5 in 10 cases, 6 in 4 cases, and 7 in 5 cases. Comparison of the 4 diagnostic scores, the difference was not statistically significant(F = 0.019, P > 0.05). Joint diagnostic results of the three members were compared with the standard and correlation coefficient were 0.977,0.987,0.932, respectively(all P < 0.01 ). The correlation coefficient of diagnostic results of each member were 0.969,0.935,0.928, respectively (all P <0.01 ). Diagnostic results of each member were consistent with the standard and the compliance rate were 88.9% (88/99) ,90.9%(90/99) and 86.9%(86/99), respectively. Conclusions B-mode ultrasonography is a non-injure method for diagnosis of carotid atherosclerosis in epidemiology investigation. The method is easy to grasp and has a good repeatability.

Objective To discuss the effects of silencing of iASPP gene on human bladder cancer cells. Methods RNAi silencing of iASPP gene in bladder cancer cell 5637 and T24 cells were used by lentiviral mediated interfering short hairpin RNAs. Cell proliferation was tested by MTT assay, and rate of colony was tested by colony formation assay. Cell cycles were tested by using fluorescence-activated cell sorting. Results Down-regulation of iASPP could inhibit the growth and proliferation of human bladder cancer cells (P<0.05). iASPP know-down could decrease the colony formation of 5637 and T24 cells (P<0, 05). Knocking down of iASPP in 5637 and T24 cells showed cell arrested at G1. Conclusions Silencing of iASPP gene could inhibit proliferation and colony formation of bladder cancer, iASPP might be an important target for gene therapy of bladder cancer.

The Qinghai⁃Tibet Plateau is known as one of the highest endemic areas of echinococcosis However,the dog infection rates of Echinococcus granulosus in the plateau regions were similar to other non⁃Tibetan areas with the high endemic,and most of the rates were below 40%. The infected dogs with E. multilocularis were ubiquitous in Ganzi Prefecture of Sichuan Province and Qinghai Province where many survey data were done and available,which was much different from those in non⁃Ti⁃betan areas where the geographical distribution of dogs infected with E. multilocularis was sporadic. The total infection rates of Echinococcus in dogs kept stable from 1983 to 2009 in Ganzi Prefecture of Sichuan Province and did not show much variation from 2000 to 2014 in Qinghai Province as well. Since 2006,the national comprehensive prevention and control strategy and mea⁃
sures against echinococcosis have been launched in China,and significant progress has been made. In the endemic Tibetan area of Sichuan,the general Echinococcus infection rates in dogs were 28.10%,15.87%,19.22%,3.28% and 1.11% from 2009 to 2013,respectively,and the Echinococcus coproantigen⁃positive rate in Gannan Prefecture of Gansu Province and parts of Qing⁃
hai Province also decreased. This paper reviews the literature on the characteristics of dog infections in the Qinghai⁃Tibetan Plateau,so as to provide useful information to support echinococcosis control and prevention there.

Objective:To find absorbable adhesives with suitable bonding properties for the absorbable polylactic acid root canal post. To test and compare the bond strengths of absorbable polylactic acid root canal post with three different adhesives. Methods:The absorbable polylactic acid root canal posts were used to restore the extracted teeth, using 3 different adhesives: cyanoacrylates, fibrin sealant and glass ionomer cement. The teeth were prepared into slices for micro-push-out test. The bond strength was statistically analyzed using ANOVA. The specimens were examined using microscope and the failure mode was divided into four categories:cohesive failure between absorbable polylactic acid root canal posts and adhesives, cohesive failure between dentin and adhesives, failure within the adhesives and failure within the absorbable polylactic acid root canal posts. Results:The bond strength of cyanoacrylates [(16. 83 ± 6. 97) MPa] and glass ionomer cement [(12. 10 ± 5. 09) MPa] were significantly higher than fibrin sealant [ ( 1 . 17 ± 0 . 50 ) MPa ] , P <0 . 001 . There was no significant difference between cyanoacrylates and glass ionomer cement (P =0. 156). In the group of cyanoacrylates, the cohesive failure between the absorbable polylactic acid root canal posts and the adhesives was 25 . 0%, the cohe-sive failure between the dentin and the adhesives was 16. 7%, the failure within the adhesives was 33. 3%, and the failure within the absorbable polylactic acid root canal posts was 25 . 0%. In the group of fibrin sealant , the cohesive failure between the absorbable polylactic acid root canal posts and the adhesives was 66 . 7%, the cohesive failure between the dentin and the adhesives was 22 . 2%, the failure within the ad-hesives was 11. 1%. In the group of glass ionomer cement, the cohesive failure between the absorbablepolylactic acid root canal posts and the adhesives was 87. 5%, the failure within the adhesives was 12. 5%. The major failure mode in fibrin sealant and glass ionomer cement was the cohesive failure between the absorbable polylactic acid root canal posts and the adhesives. No major failure modes were found in the group of cyanoacrylates. Conclusion:The bond strength of fibrin sealant is low, which cannot meet the requirement of clinical use. The bond strengths of cyanoacrylates and glass ionomer cement are suitable for clinical use. The cyanoacrylates are a kind of absorbable adhesive which has suitable bonding proper-ties for the absorbable polylactic acid root canal post.
