RESUMO

Objective:To analyze the global research hotspots in the field of pediatrics based on the Essential Science Indicators (ESI) database and explore the inspiration to domestic editors and pediatrics researchers.Methods:The journal distribution, country (region) distribution, cooperation, organization distribution, funding, publication language, hot topic words and other data of highly cited papers in the field of pediatrics in ESI database were collected and analyzed.Results:A total of 682 highly cited pediatrics papers were collected from 77 pediatrics journals included in Science Citation Index(SCI). Most of the highly cited pediatrics papers (182) were found to be published in Pediatrics.All 682 paper were published in English and frequently, characterized by multiple authors, institutions and fund support.Of 682 highly cited pediatrics papers, 435 papers were published in the United States(the first), 123 papers in England(the second) and 86 paper in Canada(the third). Novel coronavirus pneumonia, coronavirus, SARS coronavirus, autism and multiple system inflammatory syndrome are the main frontiers of global pediatric research at present.Specifically, focal pediatric system diseases mainly include respiratory system diseases, digestive system diseases, cardiovascular diseases, etc. Conclusions:ESI-based analysis of global research hotspots in the field of pediatrics provides reference materials for domestic and foreign pediatrics researchers to understand the global academic frontiers and development trends in the field of pediatrics and select topics for future scientific research.More importantly, this analysis can help domestic editors of pediatrics journals to plan topics and organize hot papers, so as to improve the academic quality and international influence of the journals.

RESUMO

BACKGROUND: Diabetic wounds are a major clinical challenge, because minor skin wounds can lead to chronic, unhealed ulcers and ultimately result in infection, gangrene, or even amputation. Studies on bone marrow derived mesenchymal stem cells (BMSCs) and a series of growth factors have revealed their many benefits for wound healing and regeneration. Platelet-rich plasma (PRP) may improve the environment for BMSC development and differentiation. However, whether combined use of BMSCs and PRP may be more effective for accelerating diabetic ulcer healing remains unclear. OBJECTIVE: We investigated the efficacy of BMSCs and PRP for the repair of refractory wound healing in a diabetic rat model. METHODS: Forty-eight rats with diabetes mellitus induced by streptozotocin were divided into four groups: treatment with BMSCs plus PRP, BMSCs alone, PRP alone, phosphate buffered saline. The rate of wound closure was quantified. A histopathological study was conducted regarding wound depth and the skin edge at 7, 14, and 28 days after surgery. RESULTS: Wound healing rates were significantly higher in the BMSC plus PRP group than in the other groups. The immunohistochemistry results showed that the expression of platelet/endothelial cell adhesion molecule 1, proliferating cell nuclear antigen, and transforming growth factor-beta1 increased significantly in the BMSC plus PRP group compared to the other treatment groups. On day 7, CD68 expression increased significantly in the wounds of the BMSC plus PRP group, but decreased markedly at day 14 compared to the controls. CONCLUSION: The combination of BMSCs and PRP aids diabetic wound repair and regeneration.
