Objective To evaluate the using and results of computer-aided detection for full-field digital mammography in Chinese women. Methods 934 individuals more than 40 years old from a specific unit in Shenyang city were screened by full-field digital mammography ( Senographe 2000D, GE) . The examination images were diagnosed firstly by the experienced radiologists and then were analyzed by the computer-aided detection system ( R2' Image Checker ) , respectively. The results from these two assays were compared. Results The prompts were generated in 799 out of 1734 normal images, false-positive rate of computer-aided detection ( CAD) was 46. 1 % in the cases with normal breast image. The correct prompts rate was 70. 5 % in the cases with breast mass, 75. 0 % in the cases with breast microcalcification and 100. 0 % in the cases with breast cancer. Conclusion Although the CAD system has showed clinical values in practice, there are still some false-positive and false-negative results.

Objective To study the protective effect of galanin on 2,3-Dimethoxy-1,4-naphthoquinone (DMNQ)-induced oxidative stress and cell damage in HEK-293A cells and its possible mechanisms.Methods The expression of galanin and its three receptors (GalR1-3) in HEK-293A were determined with RTPCR technique.The cultured HEK-293A cells were divided into four groups:Control,DMNQ,DMNQ + GAL and DMNQ + AR-M1896 and the cell viability was measured with CellTiter 96 AQueous One Solution Cell Proliferation Assay (MTS).Results The RT-PCR data revealed the presence of galanin and its receptors in HEK-293A cells.The expression level was in the order of GalR2 =Galanin ＞ GalR3 ＞ GalR1.DMNQ caused oxidative stress and cell damage in HEK-293A cells with a dose-dependent manner with an IC50 =13.4 μM.Application of galanin reduced the DMNQ-induced cellular toxicity in HEK-293A,which increased cell viability by 24.4％ and 18.8％ in 1 μM and 100 nM,respectively.AR-M1896,an agonist of GalR2 had a similar effect,increased cell viability by 8.7％ and 8.9％ in 1 μM and 100 nM,respectively.Conclusion These data suggest that galanin has a protective effect on DMNQ-induced oxidative stress and cell damage in HEK-293A cells,probably mediated by GalR2.

Objective To discuss the advantages and disadvantages of the mammography and ultrasound examination for breast cancer diagnosis.Methods Totally 84 breast cancer patients enrolled in our study.All of the patients underwent mammography before surgery,and 69 of them received both mammography and ultrasound examination.The data were studied retrospectively.Results 84 foci were found totally on mammography and were all diagnosed above ACR BIRAD grade 4 by X-ray.Two of the 13 cases smaller than 2 cm in diameter were diagnosed as grade 3 by ultrasound.Eleven cases with microcalcification were diagnosed as grade 2（1case）and 3（1case）by ultrasound.Only 1 of the 6 cases shown as distortion was diagnosed as 5 by ultrasound.Conclusion X-ray has the superiority to ultrasound for distortion and microcalcification.For the mass smaller than 2 cm in diameter,both of X-ray and ultrasound may underestimate.

Objective To evaluate the efficacy of entecavir treatment on hepatitis B patients with acute-on-chronic liver failure. Methods Eighty-four hepatitis B patients with acute-on-chronic liver failure were treated with entecavir 0.5 mg daily and Other routine drugs. Another 99 hepatitis B patients with acute-on-chronic liver failure were treated with only routine drugs as control. The survival, liver functions, hepatitis B virus (HBV) DNA level, prothrombin time (PT) were observed. The survival rates of patients with early, middle or late stage of liver failure were analyzed. The comparison of rates were done using chi-square test. The numeration data were compared by t test. The survival rates were compared using Kaplan-Meier method. Results Among patients with early stage of acute-on-chronic liver failure, the survival rate in treatment group was 63.3% (31/49), which was significantly higher than that in control group (39.7%, 23/58) (χ2=5.923, P=0.015). Among patients with middle stage of acute-on-chronic liver failure, the surviral rate in treatment group was 63.0% (17/27), which was significantly higher than that in control group (35.1%, 13/37) (χ2=4.854, P=0.028). Among patients with late stage of acute-on-chronic liver failure, four out of eight cases survived in treatment group, while one out of four cases survived in control group. In patients with serum total hilirubin (TBil) level > 342 μmol/L, the survival rate was 56.0% in treatment group, which was significantly higher than that in control group (26.8%) (χ2=9.351,P=0.002). At week 4 of the treatment, the HBV DNA reduction in treatment group was 3. 95 lg copy/mL, which was higher than that in control group (1.78 lg copy/mL) (t=5.847, P=0.001). Conclusions Entecavir treatment could improve the survival rate of hepatitis B patients with early or middle stage of acute-on-chronic liver failure. And the further study with larger population is needed in patients with late stage of liver failure. In addition, entecavir therapy could also improve the survival rate of patients with TBil >342 μmol/L.

AIM To study the therapeutic effects of Deketoprofen trometamol (D KPT) on adjuvant arthritis (AA) and its side effects on gastroduodena. METHEDS The change of primary and secondary inflammatory and the injury effect of gastroduodena treated with D KPT were observed. The effect of D KPT on prostaglandin E 2 (PGE 2) produced by peritoneal macrophage (PM) on AA rats in vitro was also observed. RESULTS D KPT (2 5, 5, 10 mg?kg -1 ) significantly inhibited primary inflammatory, secondary inflammatory and multiple arthritis of AA rats. D KPT(10 -8 ,10 -7 ,10 -6 ,10 -5 ,10 -4 mol?L -1 )inhibited the elevated PGE 2 released from PM of AA rats in vitro . D KPT (10 mg?kg -1 ) significantly injured gastroduodena on AA rats, but the degree of injuries was less than that of ketoprofen (KP) (10 mg?kg -1 ). CONCLUSION D KPT has therapeutic effects on AA rats, and its injury effect on gastroduodena is less than that of KP.
