Background: Previous studies examining the prognostic value of glucose transporter 1 in breast cancer have yielded inconsistent results. We, therefore, performed a meta-analysis to clarify this issue. Methods: The research was reported according to the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. Relevant studies were retrieved from PubMed, Web of Science, EMBASE, and Cochrane library. Results: A total of 7 reports with 1861 patients were finally chosen. GLUT1 overexpression was found to be associated with high histological grade (OR = 3.74, 95% CI = 2.45–5.69, P < .001), negative PR status (OR = 0.33, 95% CI = 0.22–0.49, P < .001), and negative estrogen receptor (ER) status (OR = 0.27, 95% CI = 0.17–0.42, P < .001). However, no significant correlation was seen between GLUT1 levels and presence of lymph node metastasis, tumor size or the status of human epidermal growth factor receptor 2 (HER2). Overexpression of GLUT1 also correlated with a poor overall survival (hazard ratio [HR] = 1.65, 95% confidence interval [CI] = 1.17–2.31, P = .004) and disease-free survival (HR = 2.35, 95% CI = 1.4–3.94, P < .001). No evidence of significant publication bias was found. Conclusion: This meta-analysis indicates that GLUT1 expression is associated with poor prognostic and a series of clinicopathological features in breast cancer. GLUT1 might be a potential biomarker and therapeutic target in breast cancer.

Chronic ulcer, including diabetic ulcer, varicose ulcer, and pressure ulcer, negatively affects patients’ quality of life. As microbiology plays an important role in the mechanism of pathology for chronic wound healing, this study concentrates on microecology environment of the wound and how Traditional Chinese Medicine (TCM) regulates wound bacteria. Method. The study took wound samples from 35 patients and analyzed bacteria variation before and after TCM treatment by 16s rRNA sequencing. All samples were evaluated from aspects of α‐diversity, β‐diversity, and Simpson’s Diversity index. Result. After total DNA extraction, PCR, and 16S rRNA sequencing of wound bacteria from 35 individuals, it was discovered that younger patients with shorter course of disease have a higher microbial diversity and were easier to recover from ulcers. Additionally, gender also played a vital role in wound healing, and a significant microbial diversity existed between male and female patients. Conclusion. Patients with chronic ulcers achieved a positive effect after TCM treatment (skin‐producing ointment). Mechanistically, TCM helped promote wound healing by regulating the wound microbiota.
