Chinese Journal of Tissue Engineering Research 2025;29(8):1659-1666
BACKGROUND:To date,the pathogenesis of pulmonary fibrosis is still unknown,and there are limited treatment options available.Numerous studies have found an important role of non-coding RNAs in the development of pulmonary fibrosis. OBJECTIVE:To review the regulatory role of non-coding RNAs in the pathogenesis of pulmonary fibrosis in recent years,in order to provide a more in-depth understanding of the pathogenesis of pulmonary fibrosis. METHODS:The first author searched the literature published from 2000 to 2024 by computer,and searched CNKI,WanFang,VIP,and PubMed databases using the search terms of"non-coding RNA,microRNA,long-chain non-coding RNA,circular RNA,pulmonary fibrosis,review"in Chinese and English.Finally,65 articles were included according to the inclusion criteria. RESULTS AND CONCLUSION:Pulmonary fibrosis,as a chronic and usually fatal lung disease,may arise not only spontaneously but also be as a secondary consequence of other diseases.It is mainly characterized by abnormal proliferation and massive accumulation of extracellular matrix in the interstitium of the lungs.Non-coding RNAs are RNA molecules transcribed from the genomes that are not involved in protein-coding processes and by virtue of their regulatory capabilities,they have become first-line molecular players in a variety of biological phenomena.Non-coding RNAs have been found to play a key role in the pathogenesis of pulmonary fibrosis,and microRNAs,long non-coding RNAs,and circular RNAs can be involved in the development of pulmonary fibrosis by influencing gene expression,post-transcriptional modifications,and intercellular signaling.This provides a new direction for the subsequent exploration of the specific molecular mechanisms of pulmonary fibrosis,and a theoretical basis and new ideas for the development of new targeted drugs for pulmonary fibrosis.

OBJECTIVE To analyze the influential factors on trough concentration (cmin) and area under the drug concentration time curve (AUC) of voriconazole (VRZ) in pediatric patients with thalassemia undergoing hematopoietic stem cell transplantation (HSCT). METHODS A total of 60 pediatric patients with thalassemia undergoing HSCT who used VRZ for prevention or treatment of invasive fungal infection were collected in our hospital from January 2021 to January 2024. The plasma concentration of VRZ was measured by high-performance liquid chromatography and the AUC was calculated. The factors affecting cmin and AUC of VRZ were analyzed using multiple linear regression. RESULTS A total of 120 cases of VRZ cmin in 60 pediatric patients was obtained and 27 cases of VRZ AUC in 26 pediatric patients were obtained. The median concentration of VRZ cmin was 0.31 mg/L; 46 cases had a cmin in 0.5-5 mg/L( 38.33%), 2 cases had a cmin>5 mg/L( 1.67%), and 72 cases had a cmin<0.5 mg/L. The median AUC of VRZ was 11.68 mg·h/L. The patient’s body weight, HSCT postoperative days, lymphocyte count, and combined use of phenytoin sodium, tacrolimus or cyclosporine had significant effects on VRZ cmin (P<0.05). Lymphocyte count and combined use of phenytoin sodium had significant effects on VRZ AUC (P<0.05). CONCLUSIONS The body weight, HSCT postoperative days, lymphocyte count, and combined use of phenytoin sodium, tacrolimus or cyclosporine are independent factors affecting VRZ cmin. Lymphocyte count and combined use of phenytoin sodium are independent factors affecting VRZ AUC.

Objective To conduct a visual analysis of the current status, hotspots, and frontiers of research on renal cell carcinoma targeted therapy using VOSviewer software. Methods Literature related to renal cell carcinoma targeted therapy published between January 1, 2006 and December 31, 2023, from the Web of Science (WOS) Core Collection database were retrieved. Eligible articles were screened and subjected to bibliometric and visual analysis using VOSviewer software. Results A total of 1, 009 articles were selected, with an overall increasing trend in annual publication volume. The top three countries in terms of publication output were the United States, China, and Italy, while the top three institutions were Harvard University, The University of Texas, and France Uni-cancer Institute. The analysis of the core author collaboration network revealed close collaboration among researchers in the United States and the United Kingdom, whereas collaboration between China and foreign countries was limited, resulting in a relatively loose collaboration network. Through co-occurrence clustering analysis of high-frequency author keywords, nine clusters were generated, with hotspots focusing on targeted and immune combination therapy, efficacy, prognosis, drug resistance, targets, and biomarkers. Conclusion Remarkable progress has been made in renal cell carcinoma targeted therapy research over the past decade; however, drug resistance and adverse reactions to targeted therapies remain challenges in clinical treatment. Research related to targeted drug resistance mechanisms, novel targeted drugs, and effective predictive biomarkers has significantly increased. Grasping the developmental trends in this fieldis crucial, and VOSviewer's visual analysis can offer an intuitive representation of the current status, hotspots, and frontiers, thereby providing researchers with a valuable reference.
