Skin flaps are frequently employed in plastic and reconstructive surgery to address tissue defects.However,their low survival rates remain a challenge,attributed to vascular crisis and necrosis.Despite numerous studies investigating drugs to alleviate flap necrosis,a comprehensive analysis of the research trend in this critical area is lacking.To gain a deeper understanding of the current status,research focal points,and future trends in drugs aimed at enhancing flap survival,a thorough retrospective analysis is imperative.This study aims to employ bibliometric methods to scrutinize the evolution,mechanisms,and forthcoming trends of drugs targeting flap survival improvement.Using VOSviewer software,we quantitatively and visually depict 1)annual temporal trends in the number of documents and citations;2)national/regional publications and their collaborations;3)institutional and authors'contribution;4)journal contribution and relevance;and 5)analysis of research hotspots and directions derived from keywords.Ultimately,we discussed the prospects and challenges of future advances and clinical trans-lation of drugs designed to enhance skin flap survival.In conclusion,the field of pharmacology dedicated to improving skin flap survival is expanding,and this study aims to offer a fresh perspective to promote the advancement and clinical application of such drugs.

Epidermal growth factor receptor (EGFR) mutations are the most common driver genes in the development of non-small cell lung cancer (NSCLC), of which mutations in exons 18-21 are frequent, especially the loss of exon 19 and exon 21 L858R mutation are the most frequent. Other rare gene mutations are rare. Simultaneous occurrence of two or more rare EGFR mutations are extremely rare in lung cancer, and the incidence of EGFR L833V/H835L rare gene compound mutations is very low, and there is little clinical data and evidence of relevant treatment methods. Some EGFR-tyrosine kinase inhibitors (EGFR-TKIs) are effective in treating lung cancer patients with rare gene mutations. In this article, we reported a case of NSCLC patient with a rare gene compound mutation EGFR L833V/H835L, who responded to Afatinib in combination with Anilotinib treatment well after 5 months of treatment, and computed tomography (CT) showed shrinkage of lung lesions. Meanwhile, we also compiled previously reported NSCLC patients with EGFR L833V/H835L rare gene compound mutation and summarized the characteristics of this group of patients and the effect of applying different kinds of EGFR-TKIs treatment.
