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.

Hepatitis C virus (HCV) infection is the leading cause of chronic liver diseases worldwide.There is no vaccine to prevent HCV infection.Current standard of care (SOC) for hepatitis C is pegylated interferon-α (pegIFN-α) in combination with ribavirin (RBV).However,the efficacy of pegIFN-α and RBV combination therapy is less than 50％ for genotype 1 HCV,which is the dominant virus in human.Additionally,IFN and RBV are highly toxic,causing severe side effects.Therefore,it is urgent to develop safer and more efficacious anti-HCV drugs.Over the last decade,a number of HCV-specific inhibitors have been discovered with many of them reached to late stages of clinical trials.Recently,2 HCV NS3 protease inhibitors,telaprevir and boceprevir,have been approved by the Unite States Food and Drug Administration (FDA).This opens up a new era for anti-HCV therapy.Several new classes of antiviral drugs targeting HCV NS3 protease,NS5A and NSSB RNA-dependence RNA polymerase (RdRp) are currently at various stages of preclinical and clinical studies.Upon approval of more NS3 protease,NS5A and NS5B polymerase inhibitors,future clinical studies will lead to optimal combination therapies which will have desirable parameters such as IFN-free,higher efficacy,safe,one daily dose and short duration.

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 provide reference for rational use of antidepressive drugs. METHODS:In retrospective study,the utilization of antidepressive drugs in 31 hospitals of Nanjing area during 2013-2015 was analyzed statistically in respects of consump-tion sum,DDDs,DDC,B/A,etc. RESULTS:There were a total of 20 kinds of antidepressive drugs in 31 hospitals of Nanjing ar-ea,and total consumption sum increased year by year,increasing from 76 085 200 yuan in 2013 to 100 812 500 yuan in 2015,in-creased by 17.43% compared to 2014 and by 12.83% compared to 2015. The top 4 drugs in the list of consumption sum and DDDs were paroxetine,escitalopram,sertraline and venlafaxine. The sum of their consumption sum accounted for more than 60% of total consumption sum. The consumption sum of plant antidepressive drugs increased rapidly. B/A and DDC of antidepressive drugs kept sta-ble each year compared to last year,among which DDC of doxepin,clomipramine and amitriptyline was less than 2 yuan,B/A val-ues of sertraline,fluvoxamine,flupentixol and melitracen,doxepin,clomipramine and amitriptyline were all more than 1.00. CON-CLUSIONS:Of antidepressive drugs in 31 hospitals of Nanjing area during 2013-2015,selective serotonin reuptake inhibitors and se-lective serotonin-norepinephrine reuptake inhibitors took up dominant place,and plant antidepressive drugs is promising in the future.
