Node negative breast cancer is a prevalent form of breast cancer .With the improvement of breast cancer screening and disease awareness ,the rates of node negative breast cancer are gradually increasing . Although node negative breast cancer patients have much lower recurrence rates as compared with node positive patients,node-negative breast cancer is unequal to a low risk disease .Thus,it is important for oncologist to esti-mate the risk factors of node negative disease ,to carry out risk assessment and to guide the best regimen for these patients.In current review ,we discuss the value of traditional prognostic factors and new prognostic factors ,such as the urokinase -type plasminogen activator/plasminogen activator inhibitor 1,oncotype DX,MammaPrint and tumor associated macrophages ,on the predictive and treatment decisions in node negative breast cancer .

Objective:To understand the mental health status of female workers in different industries in China, and to explore the influence of age, family per capita income, working hours and other factors on the mental health of female employees.Methods:From May to July 2016, a cluster sampling survey was conducted among female workers from 15 Provinces (autonomous regions and municipalities directly under the Central Government) in different industries. A total of 60230 questionnaires were distributed and 57777 valid questionnaires were recovered, with an effective rate of 95.9%. The survey included the basic information and Symptom Self-assessment Scale, etc. The measured data were in accordance with the normal distribution by normality test and were expressed as ± s. The rates of counting data were compared using the χ 2 test. And unconditioned logistic regression was used to analyze the influencing factors. Results:There were significant differences in the detection rates of mental health problems among female employees of different ages, marital status, education level, family per capita income, industry classification, working hours, and frequent night shifts ( P<0.01) . The top 3 factors of positive mental health problems were obsessive-compulsive symptoms (23.7%) , depression (16.0%) and interpersonal sensitivity (15.4%) . The factors such as age, education level, family per capita income, industry classification, working hours and frequent night shifts had statistical significances on the risk of female employees' mental health problems ( P<0.05) . Female employees aged 30-39, aged 40-49, with high school education to junior college, bachelor degree or above, engaged in tertiary industry, working time of 8-9 h/d, working time of 9-11 h/d, working time of more than 11 h/d and regular night shifts had higher risk of mental health problems ( OR=1.199, 1.187, 1.296, 1.539, 1.236, 1.674, 1.601, 1.358, 1.393, P<0.05) . Conclusion:The mental health problems of female workers are still serious, we should pay attention to the illegal long-term work and night-shift work, and take effective health promotion measures to effectively improve the mental health level of female workers.

Objective:
To investigate the infertility rate and influencing factors of female workers in China's nine industries.
Methods:
Using multi-stage sampling method, from January to November in 2016. A cross-sectional survey was conducted on the infertility of 33 685 female workers in the nine industries including medical and health, petrochemical, metallurgy, railway, machinery manufacturing and electronics,a questionnaire survey. First, three provincial capitals were randomly selected in seven regions. And then we consulted and communicated with the hospital of the provincial city's occupational disease prevention and treatment, marking and coding the target enterprise within its jurisdiction, In these enterprises, we randomly selected five companies. Finally, all women workers who meet the inclusion criteria were surveyed in those enterprises which were drawn. Use the"female workers reproductive health questionnaire" to collect female workers demographic status, occupational status and reproductive status and other data. The single factor analysis of infertility was performed by chi-square test. Multivariate analysis of infertility was carried out by logistic regression model.
Results:
The age of female workers in the nine industries was (35.98±7.98) years. The infertility rate for one year of female workers in typical industry was 24.81% (8 358/33 685), the infertility rate for two years being13.47% (4 537/33 685), the infertility rate for two years being 10.78% (3 632/33 685). Compared to the east China region, the infertility rate was the highest in the south region (
