摘要:
目的 对《中华烧伤杂志》(现《中华烧伤与创面修复杂志》)过去22年间发表的文献进行分析,探讨烧伤学科的发展趋势。 方法 通过《中国知网》数据库检索《中华烧伤杂志》2000年1月1日—2021年12月31日发表的临床及研究相关文献。采用文献计量学方法对文献按研究类型、涉及研究领域及报道的致伤原因进行分类分析,并按发表年份每3年1个时间段(将2021年文献纳入最后1个时间段中)进行比较分析。检出所有文献的关键词,经勘正和转换后,使用CiteSpace 6.1.R2软件对纳入关键词进行可视化聚类,统计高频次、高中心度关键词,同前对高频次关键词进行分时间段比较。 结果 共纳入4 485篇相关文献,平均每年约204篇文献。文献研究类型分析显示,临床诊疗文献占比最高,达65.3%(2 929/4 485);其次为细胞实验、动物实验文献,分别占18.1%(812/4 485)、13.2%(591/4 485)。各研究类型文献在各时间段的占比基本稳定。文献涉及的研究领域分析显示,烧伤全身治疗领域文献占比最高,达60.2%(2 699/4 485);其次为急性创面、整形美容领域文献,分别占20.2%(908/4 485)、7.3%(326/4 485)。烧伤全身治疗领域文献占比从2000—2002年的84.0%(430/512)下降到2018—2021年的40.3%(373/926),占比下降了43.7%;而急性创面、整形美容、慢性创面及烧伤康复领域文献占比总体呈上升趋势,与2000—2002年相比,2018—2021年占比分别上升了11.7%、9.1%、10.7%及5.5%;学科管理领域文献在前6个时间段中均很少,保持在个位数,但在2018—2021年增加至49篇。明确致伤原因的1 099篇烧伤全身治疗领域文献中,报道热力烧伤的文献最多,占58.5%(643/1 099);其次为报道电烧伤、化学烧伤的文献,分别占19.8%(218/1 099)、12.6%(138/1 099)。分时间段比较显示,报道热力烧伤的文献占比呈明显下降趋势,报道其他致伤原因的文献占比变化趋势不明显。共纳入2 236篇文献的6 822个关键词进行分析,可视化聚类分析显示相关研究侧重于烧伤、外科皮瓣、瘢痕及伤口愈合等方面,关键词频次前3位为烧伤、伤口愈合、外科皮瓣,关键词中心度前3位为烧伤、瘢痕、皮肤移植。分时间段比较显示,频次始终稳定居于前10行列的关键词仅有烧伤;随着时间的推移,内毒素/内毒素类、成纤维细胞等关键词逐渐退出频次前10行列,创伤和损伤、外科皮瓣及负压伤口疗法等关键词逐渐进入频次前10行列。 结论 《中华烧伤杂志》22年来发表文献中,烧伤全身治疗文献及热力烧伤文献逐渐减少,而慢性创面、烧伤康复等领域文献增加,外科皮瓣、伤口愈合及瘢痕防治等是目前烧伤学科的研究热点。 Abstract:Objective To analyze the literature published in Chinese Journal of Burns (now Chinese Journal of Burns and Wounds) in the last 22 years, and to explore the development trend of burn discipline. Methods The relevant clinical and research literature published in Chinese Journal of Burns from January 1, 2000 to December 31, 2021 were retrieved through China National Knowledge Infrastructure database. Bibliometrics was used to classify and analyze the literature by research types, involved research fields, and reported causes of injury, and compare them every 3 years according to the year of publication (with literature published in 2021 being included in the last time period). Keywords of all the literature were retrieved, which were corrected and conversed later. CiteSpace 6.1.R2 software was used to visually cluster the included keywords, count high-frequency and high-centrality keywords, and divide the high-frequency keywords by time as before for segment comparison. Results A total of 4 485 relevant papers were included, with an average of about 204 papers each year. The research types analysis of literature showed that clinical diagnosis and treatment literature had the highest proportion, reaching 65.3% (2 929/4 485), followed by cell experiment and animal experiment literature, accounting for 18.1% (812/4 485) and 13.2% (591/4 485), respectively. The proportion of various research types of the literature in each time period was basically stable. The analysis of the research fields involved in the literature showed that the literature in the field of systemic treatment of burns accounted for the highest proportion, reaching 60.2% (2 699/4 485), followed by the literature in the fields of acute wounds and plastic surgery, accounting for 20.2% (908/4 485) and 7.3% (326/4 485), respectively. The proportion of the literature in the field of systemic treatment of burns decreased from 84.0% (430/512) in 2000-2002 to 40.3% (373/926) in 2018-2021, with a decreasing proportion of 43.7%. While compared with that in 2000-2002, the proportions of literature in the fields of acute wounds, plastic surgery, chronic wounds, and burn rehabilitation were on the rise, with the proportions in 2018-2021 increased by 11.7%, 9.1%, 10.7%, and 5.5%, respectively. In the first 6 time periods, the number of literature in the field of discipline management was few and remained in single digits, but it increased to 49 in 2018-2021. Among the 1 099 literature in the field of systemic treatment of burns with a clear cause of injury, the literature on thermal burns was the most, accounting for 58.5% (643/1 099), followed by the literature on electrical burns and chemical burns, accounting for 19.8% (218/1 099) and 12.6% (138/1 099), respectively. The comparison by time period showed that the proportion of literature reporting thermal burns showed a significant downward trend, while the proportion of literature reporting other causes of injury did not change significantly. A total of 6 822 keywords from 2 236 literature were included for analysis. Visual cluster analysis showed that relevant studies focused on burns, surgical flaps, scars, and wound healing. The top 3 keywords in frequency were burns, wound healing, and surgical flaps, and the top 3 keywords in centrality were burns, scars, and skin transplantation. The comparison by time period showed that the only keyword with a stable frequency in the top 10 ranks was burns; with the passage of time, some keywords such as endotoxin/endotoxins and fibroblasts gradually dropped out of the top 10 ranks, while keywords such as wounds and injuries, surgical flaps, and negative-pressure wound therapy gradually entered the top 10 ranks. Conclusions Among the literature published in Chinese Journal of Burns during the last 22 years, the literature on systemic treatment of burns and thermal burns has gradually decreased, while the literature on chronic wounds and burn rehabilitation has increased. Surgical flaps, wound healing, and scar prevention and treatment are the current research hot spots in burn discipline. -
