BACKGROUND: Breast cancer patients who are positive for hormone receptor typically exhibit a favorable prognosis. It is controversial whether chemotherapy is necessary for them after surgery. Our study aimed to establish a multigene model to predict the relapse of hormone receptor-positive early-stage Chinese breast cancer after surgery and direct individualized application of chemotherapy in breast cancer patients after surgery. METHODS: In this study, differentially expressed genes (DEGs) were identified between relapse and nonrelapse breast cancer groups based on RNA sequencing. Gene set enrichment analysis (GSEA) was performed to identify potential relapse-relevant pathways. CIBERSORT and Microenvironment Cell Populations-counter algorithms were used to analyze immune infiltration. The least absolute shrinkage and selection operator (LASSO) regression, log-rank tests, and multiple Cox regression were performed to identify prognostic signatures. A predictive model was developed and validated based on Kaplan-Meier analysis, receiver operating characteristic curve (ROC). RESULTS: A total of 234 out of 487 patients were enrolled in this study, and 1588 DEGs were identified between the relapse and nonrelapse groups. GSEA results showed that immune-related pathways were enriched in the nonrelapse group, whereas cell cycle- and metabolism-relevant pathways were enriched in the relapse group. A predictive model was developed using three genes ( CKMT1B , SMR3B , and OR11M1P ) generated from the LASSO regression. The model stratified breast cancer patients into high- and low-risk subgroups with significantly different prognostic statuses, and our model was independent of other clinical factors. Time-dependent ROC showed high predictive performance of the model. CONCLUSIONS A multigene model was established from RNA-sequencing data to direct risk classification and predict relapse of hormone receptor-positive breast cancer in Chinese patients. Utilization of the model could provide individualized evaluation of chemotherapy after surgery for breast cancer patients.

Porphyromonas gingivalis peptidylarginine deiminase (PPAD), an isoenzyme of animal endogenous peptidylarginine deaminase, is secreted by the Por system and catalyzes the citrullination of arginine. Recent studies have found that PPAD can affect the formation of Porphyromonas gingivalis biofilm and reduce the body′s immune defense function, which is related to the occurrence and development of many diseases such as periodontal diseases and rheumatoid arthritis. In this paper, we reviewed the molecular characteristics of PPAD, including the genetic and functional characteristics, as well as the mechanisms related to the inflammatory and autoimmune diseases. We also pointed some issues that should be pay attention to in the further study.

0bjective To synthesis evidence of self-efficacy-based interventions to improve self-management and health behaviour change in patients with diabetes. Methods PubMed, Cochrane, MEDLINE, CINAHL, EBSCO and Web of Science were searched from 1977 to August 2018. The primary outcomes were self-efficacy and self-care ability. Pooled effect sizes of standardised mean difference ( SMD ) were calculated if outcome measurements and the units were different, and if outcome measurements and the units were the same, such as measuring blood glucose by HbA1c, weighted mean difference ( WMD ) were used to calculate pooled effect sizes. Results Nine eligible randomised control trials (RCTs) including 1578 participants were identified. The results showed that interventions based on self-efficacy significantly improved patients′self-efficacy ( SMD=0.69, 95% CI :0.58 to 0.80, P＜0.05) and self-management ( SMD=0.93,95% CI : 0.74 to 1.12, P＜0.05), helped them control blood glucose ( WMD=-0.69, 95% CI :-0.85 to-0.52, P＜0.05), reduced hospitalisation and emergency times, and improved their quality of life ( SMD=0.52,95% CI : 0.32 to 0.72, P＜0.05). Conclusions Even though the results showed significant improvement in self-efficacy and self-management after interventions, the conclusion needs to be generalised with caution because of the quality of RCTs and high heterogeneity. Future trials could consider RCTs with high quality, appropriate sample size, specific component of diabetes management, and reliable and valid scales or objective measures as outcomes.

Objective To analyze the clinical characteristics of patients with metastatic carcinoma of bone. Methods The clinical data of 217 patients with metastatic carcinoma of bone was retrospectively analyzed. The clinical features were summarized,including primary tumor,age distribution,first symptom,time of onset and bone metastatic site. Visual analogue scale(VAS)was used to evaluate the difference of pain in patients with bone metastases before and after zoledronic acid treatment. Results The bone metastasis occurred more frequently in men(male:female = 1.28:1). The majority of primary tumors were lung cancer(51.61％)and breast cancer (15.67％),respectively. The peak ages of the patients with metastatic carcinoma of bone were between 50 and 70 years old. Most of the patients with metastatic carcinoma of bone initially showed varying degrees of pain ,some of the patients with dysfunction,pathological fracture,or local lumps as the initial symptoms,only a tiny minority of patients were inadvertently found. Onset time was often within 3 months ,which accountings for 54.84％. Bone metastases were mostly in the spine,pelvis,femur and ribs,and most of the bone metastases were multiple. The VAS score of 108 patients who with bone metastases pain treated by zoledronic acid was 0～4(1.31 ± 1.07),with statistically significant differences compared with pretherapy(P<0.01). Conclusion In order to reduce the pain of patients,and to improve the quality of life and prolong the survival time,bone metastases should be diagnosed early and given comprehensive treatment.
