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.

Objective: The surgical reconstruction strategy for scar contracture deformity in chin and neck was explored, aiming to obtain better aesthetic outcome. Methods: A retrospective observational study was conducted. From December 2017 to April 2021, 34 patients with scar contracture deformity in chin and neck after burns were hospitalized in the Department of Plastic Surgery of the First Affiliated Hospital of Army Medical University (the Third Military Medical University), aged 12-54 years, including 13 males and 21 females, 4 cases with chin affected only, 7 cases with neck affected only, and 23 cases with both chin and neck affected. The scar areas were 48-252 cm². All the patients were treated by operation with expanded flaps, following the "MRIS" principle of matching of the color and thickness of the repair flaps (match), reconstructing of the aesthetic features of subunits (reconstruction), design of incision according to the plastic principle (incision), and prevention of the surgical incision scar (scar). The rectangular or kidney shaped skin and soft tissue expander (hereinafter referred to as the expander) with rated capacity of 80-400 mL was embedded in the first stage, which was routinely expanded to 3-5 times of the rated capacity of the expander. In the second stage, scar resection and expanded flap excision were performed to repair the secondary wound, and the flap donor site was sutured directly. The expansion ratio of the expander (with average value being calculated), the type of flaps used, the reconstruction of local aesthetic morphology, the appearance of postoperative incision, the survival of flap, and the situation of donor and recipient sites observed during follow-up were recorded. Results: Among the 34 patients, the average expansion ratio of the implanted expander was 3.82 times of the rated capacity of the expander. Three cases were repaired by the expanded local pedicled flap only, 19 cases by the expanded shoulder and/or chest perforator pedicled flap only, 10 cases by the expanded local pedicled flap combined with the expanded shoulder and/or chest perforator pedicled flap, and 2 cases by the expanded local pedicled flap combined with the expanded free flap of the second intercostal perforator of internal thoracic artery. After scar resection, the shapes of lower lip and chin-lip groove were reconstructed in 10 cases, chin process reconstruction and chin lengthening were performed in 16 cases, and the cervico-mental angle and mandibular margin contour were reconstructed in 28 cases. The surgical incision was concealed, most of which were located at the natural junction or turning point of the chin and neck subunits. The vertical incision of neck was Z-shaped or fishtail-shaped. All the expanded flaps in 34 patients survived after operation, of which 8 patients had minor necrosis at the edge or tip of the expanded flaps 1-3 days after operation and healed after dressing change. During the follow-up of 3-18 months, little difference in color and thickness between the expanded flap and the skin of chin and neck was observed, and the aesthetic shape of chin and neck was significantly improved, with mild scar hyperplasia of surgical incision. Conclusions: Reconstruction of scar contracture deformity in chin and neck by using expanded flaps based on the "MRIS" principle is beneficial to improve the quality of surgery and achieve better aesthetic outcome.

The study investigates the mechanism by which Peganum harmala L. (Luotuopeng, LTP) inhibits tube formation in retinal vascular endothelial cells. Tube formation was induced by treatment of retinal vascular endothelial cells with glucose. The cells were divided into a normal group, model group, and an LTP group. The total length of tube formation was measured. The active components, targets, and pathway by which LTP acts in the treatment of diabetic retinopathy was explored by network pharmacology. The mRNA expression levels of targets [extracellular signal-regulated kinase 2 (ERK2), phosphoinositide 3 kinase catalytic alpha polypeptide (PIK3CA), serine/threonine-protein kinase 1 (AKT1)] related to the mitogen-activated protein kinase (MAPK) signaling pathway and vascular endothelial growth factor (VEGF) signaling pathway was measured by real-time PCR. The results of tube formation indicated that compared with the normal group, the total tube length increased in the model group (P < 0.01); after the treatment with LTP, the total tube length decreased compared with the model group (P < 0.01). Network pharmacology revealed that the targets of LTP included PIK3CA, AKT1, and ERK2, and the pathways involved the MAPK signaling pathway and the VEGF signaling pathway. Real-time PCR indicated that compared with the normal group, the mRNA expression levels of ERK2, PIK3CA and AKT1 were elevated in the model group (P < 0.05); after treatment with LTP, the mRNA expression levels of ERK2, PIK3CA and AKT1 decreased compared with the model group (P < 0.05). LTP may inhibit retinal vascular endothelial cell tube formation by regulating the MAPK signaling pathway and the VEGF signaling pathway. This study confirms the multi-targets and multi-pathways of LTP and provides a basis for its use in the treatment of diabetic retinopathy．

Method:With “Gouty arthritis” as the research topic, the related papers during 2004—2019 were searched in Web of science core collection database and CNKI databases respectively. The results were statistically sorted out according to publication year，author，institution，literature source and key words，etc，and were visualized by CiteSpace software. Result:A total of 5 071 Chinese papers and 1 136 English papers were included. The amount of domestic and foreign publications continued to rise，forming a core team represented by LI Zhao-fu，XIONG Hui，SCHLESINGER NAOMI and other authors. The research hotpots focused on the pathogenesis，diagnosis methods， Chinese and Western medicine treatment，clinical observation，risk assessment and other aspects of gouty arthritis. Both of them had their own emphases. Domestic researches tended to focus on the treatment of gouty arthritis with traditional Chinese medicine，while foreign ones focused on the pathological research and clinical investigation of gouty arthritis. Conclusion:The number of researches in the field of gouty arthritis is on the rise as a whole，and there are both consistency and differences in the research content and hot topics between domestic and foreign literature. Therefore， we should strengthen cooperation and exchange between different teams and countries，so as to promote the overall development of this field.
