value of the 21-gene recurrence score in ER-positive, HER2-negative, node-positive breast cancer was similar

Jiayi Wu, Weiqi Gao, Xiaosong Chen, Chunxiao Fei, Lin Lin, Weiguo Chen, Ou Huang, Siji Zhu, Jianrong He, Yafen Li, Li Zhu, Kunwei Shen

Frontiers of Medicine 2021, Volume 15, Issue 4,   Pages 621-628 doi: 10.1007/s11684-020-0738-0

Abstract: Multi-gene assays have emerged as crucial tools for risk stratification in early-stage breast cancer. This study aimed to evaluate the prognostic significance of the 21-gene recurrence score (RS) in Chinese patients with pN0-1, estrogen receptor-positive (ER ), human epidermal growth factor receptor 2-negative (HER2 ) breast cancer. Among 800 patients recruited between 2009 and 2016, the median RS was 24 (0–69), with 27.4%, 46.8%, and 25.9% patients classified into low-, intermediate-, and high-risk groups. Cox regression analysis demonstrated that the high-risk category was associated with significantly higher odds of invasive disease-free survival (IDFS) and distant disease-free survival (DDFS) events compared with the low-risk category (IDFS: HR= 2.450, 95% CI 1.017–5.902, = 0.046; DDFS: HR= 2.829, 95% CI 1.013–7.901, = 0.047). No significant association between RS category and overall survival (OS) was found (intermediate vs. low: HR= 1.244, 95% CI 0.292–5.297, = 0.768; high vs. low: HR= 2.933, 95% CI 0.759–11.327, = 0.119). RS, as a continuous variable, was a highly significant predictor for IDFS (HR= 1.028, 95% CI 1.010–1.047, = 0.002), DDFS (HR= 1.030, 95% CI 1.010–1.051, = 0.003), and OS (HR= 1.034, 95% CI 1.007–1.063, = 0.014). Our findings suggested that RS may predict IDFS in Chinese patients with ER /HER2 breast cancer with N0 or N1 disease.

Analysis of the progestational eugenic result for agro-pastoralist and floating population in some areas

Yu Jiang,Shan Xiangting,Wang Jun and Xie Jinrong

Strategic Study of CAE 2014, Volume 16, Issue 5,   Pages 52-55

Abstract:

In order to understand the general state of health of the couples planning a pregnancy，carry out the progestational health education and eugenics counseling work and reduce the risk of birth defects，the data of progestational eugenic health examination for 606 pairs of couples of agro-pastoralist and floating population meeting the policy on birth and planning a pregnancy were analyzed. The number of smoking man is 381，accounting for 62.87 % of the total number of male subjects；the number of passive smoking woman is 324，accounting for 53.46 % of the total number of female subjects. A total of 152 men and women exist bad eating habits；a total of 228 men and women are exposed to pesticides and new fitment，paint and so on. The disease incidence of woman’s reproductive system phlegmonosis is the highest among the diseases detected. The results showed that the subjects are lack of progestational eugenic knowledge and apathy of eugenic sense due to the low educational level，language barriers and other factors. Therefore，we should provide comprehensive guidance for the couples planning a pregnancy according to the results of progestational eugenic health examination，so as to effectively reduce the incidence of birth defects and improve the quality of the population.

Strategic Study of CAE 2010, Volume 12, Issue 12,   Pages 18-22

Abstract:

Deformation forecast is proceeded for the structure of Beijing underground diameter side penetrating one station of metro line 2 by numerical value analysis. The comparative analysis and reasons of difference analysis is proceeded too between predicted value and measured value. Deformation prediction results have certain guiding role for engineering construction alike.
