Abstract
BACKGROUND AND PURPOSE Breast cancer is now recognized as a clinically heterogeneous disease with a wide spectrum of epidemiological and clinicopathologic features. We aimed to evaluate whether epidemiological and clinicopathologic features are associated with the histological tumor grade of breast carcinomas in Western China. METHODS We retrospectively collected data from the Western China Clinical Cooperation Group and assessed associations between clinicopathologic factors and histological tumor grade in 8619 female breast cancer patients. Patients were divided into two groups: Group I (tumor grade I/II) and Group II (tumor grade III). Univariable analysis and multivariable logistic regression models were used to analyze the relationships between clinicopathologic factors and tumor grade. RESULTS Patients presenting with positive axillary lymph nodes, large tumor size (>2 cm), lymphovascular invasion, hormone receptor negativity, human epidermal growth factor receptor 2 (HER-2) positivity, and triple negativity tended to have an increased risk of a high tumor grade. However, the number of pregnancies or births was inversely correlated with the risk of a high tumor grade. In addition, patients presenting with grade III tumors were more likely to receive aggressive treatment, such as adjuvant chemotherapy, anti-HER-2 therapy, and level III axillary lymph node dissection. CONCLUSIONS Our results suggested that several clinicopathologic factors were associated with high tumor grade of breast cancer patients in Western China.

Abstract
Circular RNAs (circRNAs) are a type of noncoding RNAs generated from back-splicing, which have been verified to mediate multiple tumorigenesis. With the development of high-throughput sequencing, massive circRNAs are discovered in tumorous tissue. However, the potential physiological effect of circRNAs in breast cancer is still unknown. The purpose of this study is to investigate the expression profile of circRNA in breast cancer tissue and explore the in-depth regulatory mechanism in breast cancer tumorigenesis. In the present study, we screened the circRNA expression profiles in breast cancer tissue using circRNA microarray analysis. Totally 1705 circRNAs were identified to be significantly aberrant. Among these dysregulated circRNAs, hsa_circ_0001982 was markedly overexpressed in breast cancer tissue and cell lines. Bioinformatics analysis predicted that miR-143 acted as target of hsa_circ_0001982, which was confirmed by Dual-luciferase reporter assay. Loss-of-function and rescue experiments revealed that hsa_circ_0001982 knockdown suppressed breast cancer cell proliferation and invasion and induced apoptosis by targeting miR-143. In summary, our study preliminarily investigates the circRNA expression in breast cancer tissue and explores the role of competing endogenous RNA (ceRNA) mechanism in the progression, providing a novel insight for breast cancer tumorigenesis.

Abstract
Objective: To investigate the effect of steroid hormones on the growth and biofilm formation of S. epidermidis. Methods: In all experiments, two S. epidermidis standard strains (ATCC12228 and ATCC35984) and two S. epidermidis clinical strains (SE101 and SE40) were incubated on the surface of silica gel in estradiol concentrations of 0, 50, 125, 250 and 500 pmol/L at 4, 6, 12, 24, 48 and 72 hours. Growth curve were drawn by means of the OD value. Formed biofilms were assessed by crystal violet staining methods. In order to observe the processes and structures of biofilm, the confocal laser scanning microscopy (CLSM) and scanning electron microscope (SEM) were used. Results: All of the four strains which were incubated with the concentrations of 125 pmol/L of estradiol had entered the logarithmic growth stage ahead of the blank control (3 h and 4 h). Crystal violet staining indicated that there was no biofilm for ATCC12228. Improved primary attachment abilities were found for ATCC35984 and SE101 in the presence of estradiol, and the OD values were 0 pmol/L (0.081±0.015 and 0.082±0.011), 50 pmol /L (0.087±0.013 and 0.088±0.010), 125 pmol/L (0.175±0.052 and 0.091±0.012), 250 pmol/L (0.153±0.036 and 0.090±0.006), 500 pmol/L (0.157±0.050 and 0.082±0.032), respectively. The thickness of biofilm reached the peak in 125 pmol/L estradiol at 24 h. CLSM and SEM found estradiol promoted the biofilm maturity and the biofilm of 125 pmol/L group was denser and thicker than that of the other concentration groups. Conclusions: Our in vitro experiments indicate that estradiol could promote the growth of S. epidermidis which exit on the surface of silica gel, and improve the ability of biofilm formation of S. epidermidis.

Abstract
BACKGROUND & OBJECTIVE The general module of the system of quality of life instruments for cancer patients, QLICP-GM, has been developed by us. Based on it, this study was to develop and evaluate the quality of life instrument for patients with breast cancer (QLICP-BR). METHODS Using the structured group methods of instrument development, the instrument with Chinese cultural background was developed, and evaluated by analyzing the data from 186 breast cancer patients. RESULTS The test-retest reliability for the overall scale and 5 domains were all above 0.75. The internal consistency alpha for each domain was higher than 0.65 except social domain (0.58). Most correlation coefficients between each item and the domain (that the item belongs to) were above 0.60. The differences between the scores before treatment and the scores after treatment for overall scale, general module, physical domain, psychologic domain, and social domain were significant. CONCLUSION The QLICP-BR is of good validity, reliability and reasonable responsiveness, and can be used to assess quality of life for breast cancer patients.
