Scientific journals are an important platform for academic exchange and dissemination, as well as for promoting technological innovation. This article is based on the publishing practice of the Chinese Journal of Radiological Medicine and Protection in recent years, especially after being successfully selected in the Excellent Action Plan of Chinese Science and Technology Journals. It aims to gather high-quality manuscript sources and strictly control academic quality; Pay attention to academic hotspots and strengthen content construction; Based on the characteristics of publishing, create high-quality works; To fulfill our original mission, shoulder social responsibility, strengthen academic leadership, enhance brand value, and explore how to improve the quality and dissemination of academic journal content and influence, in order to better showcase and promote China's achievements in radiation medicine and protection.

In response to the national strategy of building first-class journals and filling the gaps in English journals on radiation medicine and protection, the Radiation Medicine and Protection (RMP) was founded. Within three years, it has entered domestic and international databases such as DOAJ, Scopus, CSCD, WJCI and Embase with its CiteScore ranking first in the discipline and WJCI index surpassing a variety of international authoritative radiation protection journals. Collaborating with KeAi and Elsevier successively, this open access publisher has gained a significant number of international citations to achieve international visibility. Owing to the influence of disciplinary characteristics, domestic evaluation systems, and international exchange situation, RMP is facing development bottlenecks. We hope to explore breakthrough measures from the aspects of expanding manuscript sources, strengthening academic exchanges, and attracting young experts to joining the editorial board.

Objective:To retrieve, evaluate and summarize the best evidence for the prevention and management of stress urinary incontinence in pregnant and postpartum patients, and provide a reference for the standardized management of clinical medical staff.Methods:All domestic and international evidences on the prevention and management of stress urinary incontinence during pregnancy and postpartum patients were systematically searched, including clinical decisions, guidelines, expert consensus and systematic reviews. The retrieval time limit was from the establishment of the database to March 20, 2022. Two researchers independently conducted literature screening and quality evaluation, and extracted and summarized the included literature.Results:A total of 10 articles were included, including 1 clinical decision, 3 guidelines and 6 systematic reviews. A total of 29 pieces of best evidence were summarized from five aspects, including risk factors, risk assessment, intervention measures, education and training and follow-up.Conclusions:This study summarizes the best evidence for the prevention and management of stress urinary incontinence in pregnant and postpartum patients. Clinicians should refer to the best evidence and combine the patient's own condition to conduct standardized management of the disease.

Background: Excessive delivery of free fatty acids (FFAs) to the liver promotes steatosis and insulin resistance (IR), with IR defined as reduced glucose uptake, glycogen synthesis and anti-lipolysis stimulated by normal insulin levels. Whether the associations between FFAs and diabetes development differ between patients with and without nonalcoholic fatty liver disease (NAFLD) remains unclear. Methods: Consecutive subjects (2,220 NAFLD subjects and 1,790 non-NAFLD subjects according to ultrasound imaging) were enrolled from the First Affiliated Hospital of Sun Yat-sen University between 2009 and 2019. The homeostasis model assessment of insulin resistance (HOMA-IR) was calculated. Results: There was an approximate J-shaped relationship between FFA levels and HOMA-IR in the NAFLD group. Higher FFA concentration quartiles were associated with higher risks of IR (odds ratio [OR], 9.24; 95% confidence interval [CI], 6.43 to 13.36), prediabetes (OR, 10.48; 95% CI, 5.66 to 19.39), and type 2 diabetes mellitus (T2DM; OR, 19.43; 95% CI, 12.75 to 29.81) in the NAFLD group but not in the non-NAFLD group. The cut-off points for the FFA levels increased in a stepwise manner in discriminating IR, prediabetes and T2DM (573, 697, and 715 μmol/L) in the NAFLD group but not in non-NAFLD individuals. Conclusion A distinct dose-dependent relationship of FFA levels was found with IR, prediabetes and T2DM in NAFLD patients. Screening serum FFA levels in NAFLD patients would be valuable in preventing diabetes development.
