Objective The purpose of this study was to investigate the effects of a breast cancer screening educational program on women's knowledge and intention to seek breast cancer screening in China.Methods 60 patients were divided into the experimental group (30 cases) and the control group (32 cases).The experimental group received breast cancer screening educational program,while the control group did not.A pre-test and post-test were used in both the experimental and the control groups.A convenience sampling was used.Two structured questionnaires were used.Results The mean scores of knowledge of breast cancer screening and intention to seek breast cancer screening of the experimental group were statistically different from those of the control group after the education.Statistical difference also existed in the experimental group in the above aspects within the experimental group.Conclusions Application of breast cancer screening educational program can improve women's knowledge and intention to seek breast cancer screening,as well as supply reference for prevention item of breast cancer.

Objective To study the application value and safety of sentinel lymph node biopsy ( SLNB) replacing axillary lymph node dissection ( ALND) for patients with early breast cancer .Methods Data was col-lected for patients undergoing SLNB or ALND in the Second Hospital of Dalian Medical University from June 2011 to June 2014.The complication of upper extremity , axillary local recurrence and distant metastasis were retro-spectively analyzed.The patients were followed up to Nov .2014, with the median follow-up of 41 ( 18-52 ) months.Results Patients undergoing SLNB had less postoperative complications of upper extremity ( numb and painχ2 =18.174, P =0.000;Restricted movement χ2 =20.413, P =0.000; Strength loss χ2 =23.785, P =0.000;P<0.05).There was no statistical difference for the postoperative complications of axillary local recur-rence and distant metastasis (χ2 =0.555, P=0.516; P>0.05).Conclusion In early breast cancer without SLN, SLNB can achieve the equivalent effect to ALND with less damage and complications .

Objectives: To explore the effects of 13-cis-retinoic acid (13cRA) alone or combined with interferonα-2b (IFNα-2b) for the inhibition of cell growth and apoptosis induction of mantle cell lymphoma cell lines Jeko-1 cells. Methods: Jeko-1 cells were treated by different concentrations of 13cRA alone or combined with IFN-α2b. CCK-8 was used to measure the inhibition effects by different treatments. Cell cycles were analyzed by flow cytometry. Effects on apoptosis were assessed by staining of Annexin Ⅴ/PI. And the levels of Cyclin D1, caspase-9 and Rb proteins were measured by Western blot method. Results: 13cRA alone at different doses and its combination with IFNα-2b inhibited Jeko-1 cells growth and induced apoptosis, but the combination had higher inhibition potential and significant apoptosis rate (P<0.05) . The growth inhibition and apoptosis induction in Jeko-1 cells increased significantly with the elevation of drugs concentration and treating duration (P<0.05) . As well as the percentage of Jeko-1 cells at G₁/G₂ phases increased (P<0.05) and cells at S phase decreased (P<0.05) , the levels of Cyclin D1 and Rb decreased with elimination caspase-9. Conclusion 13cRA, IFN-α2b and their combined administration inhibited cells growth and induced apoptosis, decreased the cell populations at S phase and blocked the cells at G₁/G₂ phase. Combination of the drugs may have a cooperated action. The therapeutic synergistic effects of 13cRA and IFN-α2b were assumed to lower the expression of Cyclin D1 and Rb proteins, and induce apoptosis by activating caspase-9 pathway.

Insufficient volume of future liver remnant (FLR) often leads to the complications including liver failure and even death and thus remains a bottleneck for liver surgery. Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) is a newly developed two-stage hepatectomy procedure which can promote rapid regeneration of FLR, but the related mechanism has not yet been elucidated. With reference to the recent research advances in China and foreign countries, this article reviews the hemodynamic and humoral factors for ALPPS in promoting liver regeneration, the effect of ALPPS on liver parenchymal cells, and the role of non-parenchymal liver cells (including hepatic stellate cells, natural killer cells, macrophages, and liver progenitor/stem cells) in regulating liver regeneration. It is pointed out that the interaction between non-parenchymal liver cells and parenchymal cells is a hotspot in the research on the mechanism of liver regeneration after ALPPS.

Objective:To investigate the prevalence of depression symptoms in residents, and to analyze the demographic characteristics, training status and psychological influencing factors in order to provide the evidence for the mental health management and intervention of residents in China at current stage.Methods:A total of 1 050 participants from eight different training centers in Shenyang, Dalian, Jinzhou and Fushun of Liaoning Province were investigated by Pittsburgh sleep quality index, International physical activity questionnaire, Survey of perceived organizational support, Psychological capital questionnaire and Minnesota satisfaction questionnaire, which covered questions including social demographic information, training information, sleep status, physical activity, organization support, psychological capital, job satisfaction and depressive symptoms of residents. SPSS 22.0 were used to carry out statistical analysis such as logistic regression.Results:A total of 962 valid questionnaires were collected and the results showed that 44.59% (429/962) of residents had depressive symptoms. High training grade ( ORPGY-3=1.775, P=0.006) and poor quality of sleep ( OR=1.662, P<0.001) were risk factors of depressive symptoms, whereas psychological capital ( OR=0.962, P<0.001) and job satisfaction ( OR=0.972, P=0.001) were protective factors of depressive symptoms. Conclusion:The prevalence of depressive symptoms is high in residents. Training grade, sleep quality, psychological capital and job satisfaction are closely associated with the high prevalence of depressive symptoms, which should be paid more attention to.

OBJECTIVETo Explore the poor prognostic factors of diffuse large B-cell lymphoma (DLBCL).

METHODSThe clinical data of 409 newly diagnosed patients with DLBCL from January 2000 to December 2010 were collected, and the prognostic factors by univariate and multivariate stratification were analyzed .

RESULTSOf the 409 DLBCL patients, 244 were males and 165 females, the median age was 56(16-89) years old, the median follow-up time was 23(2-108) months. In univariate analysis, age, clinical stage, B symptoms, ECOG scores, the international prognostic index (IPI) scores, bone marrow involvement, low absolute lymphocyte count (ALC), high LDH, β2-MG>2 times of normal, regimen and therapeutic effect had significant influence on OS and PFS (P<0.05). Multivariate analysis showed that stage III-IV and high LDH were the poor prognostic factors of OS and PFS (P<0.05). When IPI scores were included, low ALC and IPI 3-5 scores were the poor predictors of OS and PFS in CHOP-like group (232 cases), revised IPI (R-IPI) was an independent poor predictors of OS and PFS in RCHOP-like group (177 cases).

CONCLUSIONStage III-IV and high LDH have negative influence on OS and PFS in patients with DLBCL, low ALC and IPI 3-5 scores affect OS and PFS in CHOP-like group, R-IPI affects OS and PFS in RCHOP-like group.

OBJECTIVETo investigate the clinical characteristics, therapeutic effects, long-term survival and prognostic factors of the newly diagnosed patients with Hodgkin lymphoma (HL).

METHODSOne hundred and thirty five newly diagnosed HL patients in West China hospital from January 1, 2000 to December 31, 2010 were analyzed retrospectively. Software SPSS18.0 was applied to determine the risk factors for therapeutic results and long term survivals.

RESULTSOf 135 patients, 78 cases were male and 57 female, the median age was 32(7-77) years old, and the median follow-up of 42(12-141) months. The peak age of HL was 20 to 30 years old and lymph node enlargement was the first presenting symptom in 69.63% of the patients. Among the all pathological types of HL, mixed-cellularity subtype (MC) and nodular sclerosing (NS) were the most common types, accounting for 59.7% and 34.0%, respectively. In MC subtypes, 66.2% of patients were male, while in NS subtypes, 61.4% were female. Among the 114 patients with complete follow-up data, 73 patients (64.0%) obtained complete remission and the total response rate was 77.2%. The 2-, 3- and 5-year overall survival (OS) rates were 91.2%, 88.0% and 80.9%, respectively. The progression free survival rates were 76%, 80.3% and 81.6%%, respectively. Among the patients with early unfavorable prognosis, 96.3% of them accepted full course chemotherapy and 13(48.1%) were combined with local radiotherapy. The 3- and 5- year survival rates of early unfavorable patients were higher than that of early favorable and advanced patients, but the difference was not statistically significant. Age≥45 years old and B symptom were adverse factors affecting curative effect for MC and NS subtypes, respectively. Furthermore, Age≥45 years, B symptoms and hepatomegaly were independent risk factors affecting the survival.

CONCLUSIONHL is more common in young patients (age<45 years old) and usually diagnosed at the early stage, with predominance of MC subtypes. B symptoms were adverse prognostic factors of therapeutic effects. The standard- dose chemotherapy and suitable courses of treatment combined with radiotherapy may provide the best benefits for the HL patients.
