Objective To investigate androgen receptor (AR) expression in triple negative breast cancer(TNBC) patients and its predictive value for clinical outcomes.Methods Five hundred and sixty-eight primary breast cancer patients who received surgery treatment from January 2008 to January 2010 were included in this study.Tissue sections of surgical resection specimens were underwent estrogen receptor (ER),progesterone receptor (PR),and human epidermal growth factor receptor 2 (HER2) immunohisto chemical staining,according to the judgment for triple negative breast cancer and non triple negative breast cancer.Data on age,family history,menstruation,tumor size,tumor stage,tumor grade,pathological type and lymph node metastasis were collected for analysis.Immunohistochemical analysis of AR was done in tissue sections of triple negative breast cancer patients,Kaplan-Meier method was used to compare survival between AR(+) and AR(-) groups,and Log-rank method was used to determine the association between AR-positive expression and 5-year overall survival as well as disease free survival.Results Among 568 breast cancer patients,174 (30.6％)TNBC patients were identified,including 84 patiens with AR (-) expression and 90 patients with AR (+) expression.During 5 years' follow-up,reccurrence rate was 35.7％ (30/84) in AR (-) group and 20.0％ (18/90) in AR(+) group;5-year overall survival rate was 73.8％ in AR(-) group and 81.1％ in AR(+) group.There was no significant association between AR(+) expression and 5-year death or recurrence rate,while after adjusting for age,menstruation,tumor size and lymph node metastasis,AR (+) expression was significantly associated with decreased 5-year death and recurrence rate,adjusted hazard ratio (HR) was 0.794,95CI (0.430-1.021) and 0.722,95CI (0.451-0.965) respectively.Conclusion AR (-) expression is associated with increased risk of death and recurrence and is a promising predictive marker for poor clinical outcomes.

Objective To investigate the general self-efficacy of the clinical nurses and explore the relationship between general self-efficacy and job burnout .Methods 473 clinical nurses from 13 hospitals of the third and the second grade in Leshan city were recruited and investigated with general self-efficacy scale and mashach burnout inventory .Results (1)The mean score of the clini-cal nurses′general self-efficacy was(2 .63 ± 0 .49) scores ,which was lower than that of military nurses (2 .69 ± 0 .58) scores (P<0 .05) .(2)There was a significant difference of nurses′general self-efficacy in different employment types ,administrative positions , marital statuses ,length of service and professional titles (P<0 .05) .(3)The score of general self-efficacy was negatively correlated with that of emotional exhaustion and of depersonalization (P<0 .01) ,but positively correlated with that of personal accomplish-ment(P<0 .01) .Conclusion Nurses′overall general self-efficacy was at a moderate level .Administrators could reduce nurses′job burnout more effectively by improving their self-efficacy .

Objective:To clone and express mouse fibroblast growth factor eight(FGF 8) and investigate the function of it Methods:According to the published sequence of mouse fibroblast growth factor 8, a pair of special primers was designed Then the full length cDNA of FGF 8b (a predominant isoform of FGF 8) was isolated from the total RNA of the mouse embryo by means of reverse transcription PCR and subcloned into the yeast expression vector of pYEX4T 1 in correct direction It was identified with sequencing The recombinant plasmid was transformed into yeasts The fusion protein expressed was verified by using Western blot The activity of the protein was examined by MTT and 3H TdR incorporation Results:The cDNA fragment was about 600 bps, and proved to be "b" isoform of FGF 8 exactly This fusion protein, with molecular weight about 55 kD, was highly expressed in yeast system The data of MTT and 3H TdR incorporation in NIH3T3 cells were increased obviously by the protein, and decreased by the antagonist Conclusion:Fibroblast growth factor eight was cloned and expressed.The protein was found to be capable of stimulating the proliferation of NIH3T3 cells Moreover, the recombinant protein of the extracellular fragment of FGFR1 can antagonize the response of NIH3T3 to the recombinant protein

The ras-mitogen activeted protein kinase pathway is responsible for regulation of many cel-lular processes, including differentiation, cytoskeletal organization, and protein trafficking. Much attention has been paid to them and their role in cancer therapy recently, and its inhibitor pathways are applied to clinical tes-ting, such as, Raf kinse inhibitors, MEK inhibitor, Src kinase inhibitor.

SUMMARY Salivary gland tumors are a group of the most common tumors in the oral and maxillofacial region with obvious characteristics of clinical , histopathologic , and therapeutic aspects .During the past 50 years, our research group performed a systemic study on salivary gland tumors including imaging diag-nosis, fine needle aspiration cytology , FT-mid-IR fiber optics spectroscopy , histopathologic features and biological behaviour of the tumors , functional parotid surgery , and 125 I seed implant branchytherapy . More reasonable principles of management for various types of the tumors were put forward based on the histopathologic features of the tumors .The surgical techniques were modified and the postoperative com-plications were reduced obviously .Thus, the quality of life of the patients was improved greatly .
