Many hospitals put forward suggestions on strengthening English training and attaching importance to team cooperation and so on.Conclusions:In our country, Robotic-assisted surgery nurses′ training has turned to that training themselves in operating rooms, the training time, form, content and other aspects have no uniform standard, strict admittance, standardization of specialist training , these are questions need to solve.

Objective The objective of this study was to investigate and understand the life quality and its influencing factors in breast cancer patients with chemotherapy. Methods Based on the European Research and Treatment Association,the EORTC-BR53 scale consisting of QLQ-C30 and QLQ-BR23 was used as the main basis to design a questionnaire to investigate the life quality of breast cancer patients with chemotherapy. The rank sum test was used to evaluate the survival of breast cancer patients with chemotherapy. The grade logistics univariate and multivariate analyses were used to analyze the factors of prognosis and life quality of breast cancer patients. Results The median fun scores of QLQ-BR23 scale in the groups of <35 months,36~59 months and more than 60 months were 0,0,and 66. 67,respectively( P<0. 05). The median scores of annoy caused by alopecia were 33. 33,33. 33, and 10. 33 in three groups mentioned above,respectively(P<0. 05). The median scores of physical function of QLQ-C30 scale for modified radical mastectomy,segment plus sentinel and breast-conserving patients were 66. 67,66. 67,and 73. 33,respectively(P<0. 05). The median scores of nausea and vomiting in the modified radical mastectomy was 16. 67,and others were 0;the median scores of shape physique of QLQ-BR23 in three groups were 91. 67,100 and 100,respectively( P<0. 05);the median scores of sexual function were 0,16. 67 and 50,respectively(P<0. 05),and the median scores of sexual fun were 0,33. 33 and 66. 67,respectively(P<0. 05). To analyze the total symptoms of life quality,causing borrow money and pathological classification were the factors affecting the total life quality of breast cancer patients with chemotherapy(P<0. 05). The total symptoms of life quality were analyzed. Univari-ate analysis showed that borrows money due to illness and ductal carcinoma in pathological classification had significant. Conclusion The life quality of breast cancer patients with chemotherapy is mainly related to the pathological stage of patients and whether they have economic pressure.

Objective The objective of this study was to investigate the relationship between the methylation of phosphodies-terase 4C(PDE4C)gene in peripheral blood leukocytes,and its interaction with environmental factors and the pathogenesis of breast cancer. Methods A case-control study was conducted to select 402 cases of breast cancer and 470 cancer-free controls from Octo-ber 2010 to December 2014. The specific DNA methylation-modified quantitative PCR method was used to detect the methylation of PDE4C gene. The use of crossover analysis and multivariate logistic regression was used to analyze the relationship between the level of gene methylation and its interaction with environmental factors and the pathogenesis of breast cancer. Results PDE4C methylation was not found to be significantly associated with the onset of breast cancer. High-frequency/high-intake of whole grains,vegetables, onion-based plants,poultry,milk,and regular exercise could reduce the risk of breast cancer;high-frequency/high-intake of pork, irregular menstrual cycle,and a high psychological stress index could increase the risk of breast cancer. PDE4C hypermethylation had a significant combining effect with edible onion-producing plants greater than 3 times/week,with an OR of 0. 373(95% CI:0. 208~0. 668,P=0. 001). Conclusion Hypermethylation of PDE4C is not an independent risk factor for breast cancer,and its combination with environmental factors affects the risk of breast cancer.

To establish a time-resolved fluorescence immunochromatographic assay for quantitative determination of carbohydrate antigen 19-9 (CA19-9) in serum, we prepared CA19-9 test strips by integrating double-antibody sandwich method and fluorescence immunochromatography technique. Carboxy fluorescent microspheres and nitrocellulose membrane were used as carriers for labeling and coating CA19-9 pairing antibodies. We optimized the process by adjusting the amount of labeling and coating antibody. According to the linear range, lowest detection limit and precision, We evaluated the time-resolved fluorescence immunochromatographic assay of CA19-9. When the amount of labeled antibody was 80 μg for 20 μL fluorescent microspheres, and the concentration of coated antibody on the test line was 1.5 mg/mL, the optimal reaction time was 15 minutes. Assay linear range was 12.5 to 800 U/mL and the minimum detection limit was 6.32 U/mL. The Within-run and between-run coefficient of variation were less than 15%. Average recovery rate was 101%. By detecting 50 clinical samples in parallel with Roche electrochemical luminescence detection kit, correlation coefficient was 0.980 6. The experiment, initially established a fluorescence immunochromatographic detection method to quantitative detection of serum CA19-9, which has a good clinical application prospect.
