Development of Thermoplastic Polyurethane Films for the Replacement of Corneal Endothelial Function of Transparency Maintenance

Endothelial keratoplasty is the main surgical procedure for treating corneal endothelial dysfunction (CED), which is limited by the global shortage of donor corneas. Herein, we developed and evaluated the modified thermoplastic polyurethane (M-TPU) films with gelatin-glycidyl methacrylate to replace the corneal endothelial function and maintain corneal transparency. The films displayed comparable light transmission characteristics with normal corneas and clinically favorable mechanical properties for surgical manipulation. After surface modification, the hydrophilicity and biocompatibility of M-TPU films were significantly improved. In the rabbit CED model, the M-TPU implants exhibited firm adhesion to the exposed stromal surface. The rabbit corneal transparency and thickness could be restored completely within 1 week of M-TPU film implantation. There was no significant inflammatory reaction and immune rejection during the follow-up of 1 month. Proteomic analysis suggested that the complement inhibition, the increase of mineral absorption, and the decrease of P53 apoptosis signaling pathway and lysine degradation might be beneficial in maintaining the corneal transparency. Overall, our study demonstrated the potential of M-TPU films as artificial implants for the replacement of corneal endothelial function to restore corneal thickness and transparency.

Global trends of targeted therapy for hepatocellular carcinoma: A bibliometric and visualized study from 2008 to 2022

BACKGROUND

Hepatocellular carcinoma (HCC) is an exceedingly prevalent malignancy with an exceptionally poor prognosis. Targeted therapy is an effective treatment option for patients with advanced HCC. However, there have been no bibliometric analyses of targeted therapies for HCC.

METHODS

This study aimed to assess the current status and future directions of targeted therapy for HCC to provide future scholars with clearer research contents and popular themes. Methods: Literature on targeted therapy for HCC from 2008 to 2022 was obtained from the Web of Science (WoS) and assessed using bibliometric methodology. Additionally, the VOS viewer was applied in the visualization study to conduct bibliographic coupling, co-authorship, co-citation, and co-occurrence analyses of publications.

RESULTS

A total of 10,779 papers were subsequently selected. Over the past 15 years, there has been a progressive increase in the number of publications on an annualized basis. China released the most publications in the field, whereas the United States had the highest H-index. Cancers published the most papers. Fudan University had the greatest sway in this area. Studies could be divided into 5 clusters: "Gene and expression research," "Mechanism study," "Nanoparticle study," "Targeted drug research," and "Clinical study."

CONCLUSIONS

In the upcoming years, more papers on targeted therapy for HCC are expected to be released, demonstrating the potential for this topic to flourish. Particularly, "Clinical study" is the following trendy topic in this field. Other research subfields may likewise exhibit a continuous tendency towards balanced development.

Retinogenesis in a Dish: Bibliometric Analysis and Visualization of Retinal Organoids From 2011 to 2022

Retinal organoid (RO) is the three-dimensional (3D) retinal culture derived from pluripotent or embryonic stem cells which recapitulates organ functions, which was a revolutionary milestone in stem cell technology. The purpose of this study is to explore the hotspots and future directions on ROs, as well as to better understand the fields of greatest research opportunities. Eligible publications related to RO from 2011 to 2022 were acquired from the Web of Science (WoS) Core Collection database. Bibliometric analysis was performed by using software including VOSviewer, CiteSpace, and ArcGIS. A total of 520 articles were included, and the number of annual publications showed a rapid increase with an average rate of 40.86%. The United States published the most articles (241/520, 46.35%) with highest total citation frequencies (5,344). University College London (UK) contributed the largest publication output (40/520, 7.69%) and received highest total citation frequencies. Investigative Ophthalmology & Visual Science was the most productive journal with 129 articles. Majlinda Lako contributed the most research with 32 articles, while Olivier Goureau has the strongest collaboration work. Research could be subdivided into four keyword clusters: "culture and differentiation," "morphogenesis and modeling," "gene therapy," and "transplantation and visual restoration," and evolution of keywords was identified. Last decade has witnessed the huge progress in the field of RO, which is a young and promising research area with extensive and in-depth studies. More attention should be paid to RO-related models and therapies based on specific retinal diseases, especially inherited retinopathies.
