Objective To analyse the necessity and feasiblity about the diagnosis and classification of fibrocystic disease of breast,through using synthesize imaging methods , to increase the disease ＇s diagnosis rate. Methods Using imaging checks (molybdenum photography,ultrasonography and infra-red scanner) for 600 breast＇s cases and contrast to pathogenesis if they were done operations. Results 143cases were normal,166 cases got other disease of breast,291 cases were fibrocystic disease of breast(48.1%) ,155 cases of them were performed operations and pathogenesis. the diagnosis similar rate between performed operations check and pathogcnesis was 83.2%. Conclusion The sensitivity of three kinds imaging check method is different each other,but one method can give some help each other. The synthesize imaging check can increase the diagnosis rate and avoid mis-diagnosis and doing needless operations.

Carotid cavernous fistula is the abnormal arteriovenous communications, which can be located within the internal carotid cavernous segment itself, or between the cavernous and the internal carotid branches or external carotid meningeal branches. With the development of interventional neuroradiology, endovascular embolization has become the choice of treatment for the carotid cavernous fistula, as the technique is less invasive, simple and reliable. This paper aims to review the recent progresses in this respect in order to further improve its clinical diagnosis and treatment.

Objective To study the meaning of breast cancer staging system by AJCC eighth edition to invasive lobular carcinoma and analysis the clinical pathological characteristics.Methods According to the eighth edition of the AJCC staging to evaluate the TNM stage and prognosis evaluation of invasive lobular carcinoma cancer patient in Peking University Shenzhen Hospital from 2011 to 2016,and compared with others in clinical pathological data.Results There were 21 cases of invasive lobular carcinoma,accounting for 2.7％ of all invasive breast cancer.We found that invasive lobular carcinoma shows no significant difference (P ＞ 0.05) in ages,menstrual status,molecular features and anatomic staging and prognosis staging with others;histological grade were significantly different (P ＜ 0.05).There were significant differences in the prognosis and staging of invasive lobular carcinoma.Conclusions Eighth AJCC staging systemn provides a new reference for the clinical treatment of breast cancer,should be evaluated with anatomic stage.Histological grade is relatively good in invasive lobular carcinoma and the prognosis is good,needs more research to the individualized treatment of invasive lobular carcinoma.

Objective To evaluate the effectiveness of Typodont-based table clinic competition (TCC) on undergraduate orthodontic education. Methods Students who have finished basic orthodon-tic courses made diagnosis,treatment strategy and performed orthodontic treatment for malocclusion cases on Typodonts. A self-design questionnaire was employed to investigate their perception to this pedagogy. Results The majority of participants(82.2%-92.9%) highly evaluated Typodont-based TCC. Conclu-sions Typodont-based TCC course is conducive to arousing students' study internets and to promoting association between theory and practice.

Objective To systematically assess the efficacy of endoscopic operation and open operation for treating carpal tunnel syndrome .Methods The computer retrieval from MEDLINE ,EMBASE ,Cochrane August ,CNKI ,VIP ,Wanfang databases were conducted for collecting all related randomized controlled trials (RCT ) from February 1989 to February 2012 .The included litera-tures were performed the data extraction ,assessment of bias risk and the quality evaluation .Mata analysis was performed by the RevMan 5 .1 .6 software .Results 21 RCTs including 1 863 operations ,982 cases endoscopic carpal tunnel release (ECTR) and 881 cases of open carpal tunnel release(OCTR) ,met the inclusion criteria .Meta analysis showed that the differences in terms of postop-erative grip strength ,two points discrimination ,incidence of complications ,satisfaction rate ,postoperative symptom relief rate and operation time between the ECTR group and the OCTR group had no statistical significance .The ECTR group was better than the OCTR in the aspects of the time returnning to work ,pinch strength ,postoperative pain rate .Conclusion The ECTR group is supe-rior to the OCTR group in terms of the time returnning to work ,pinch strength ,postoperative pain rate .The other related indexes have no obvious differences between the two kinds of operation procedures .Due to the poor quality of some RCTs ,the above conclu-sion needs more high-quality ,large-sample clinical researches to confirm .

Objective To explore a preliminary health behavior self-efficacy scale for functional dyspepsia patients,and supply a practical evaluation tool for clinical nurses.Methods Through literature review,group discussion and expert interview,the authors established the preliminary index system.The Delphi method was used to organize two rounds of 20 experts consultations.Results In the two rounds of expert consultations,experts positive coefficients were 100％,respectively.The authoritative coefficient of experts was 0.83,respectively.The Kendall's W coefficients were 0.23 and 0.29.The evaluation system included 5 dimensions,11 evaluation indicators,and 42 evaluation items.Conclusions The reliability of the self-efficacy scale developed with Delphi method is relatively high and it can acted as an evaluation tool for self-efficacy and health education of patients with functional dyspepsia.
