    Abstract AbstractAim: To investigate the treatment of intractable epistaxis after radiotherapy for nasopharyngeal carcinoma (NPC).Methods: This review focuses on the anatomy and pathophysiology, mechanism, and clinical treatments of epistaxis after NPC radiotherapy.Results: For treating NPC, radiation therapy is the primary therapeutic modality. However, radiotherapy can lead to varied degrees of harm to the neighboring tissues and is correlated with numerous complications. Among these complications, epistaxis is a common occurrence after NPC radiotherapy, owing to damage to the surrounding tissues caused by radiotherapy. Unfortunately, epistaxis, particularly carotid blowout, can have a dangerous course and a high mortality rate. Accurate understanding of epistaxis following radiotherapy, prompt bleeding cessation, and reduction of bleeding volume are key considerations. Nasal tamponade is a crucial rescue treatment, while tracheotomy is an active and effective method. Intravascular balloon embolization is a reliable and effective treatment method for ICA hemorrhage, and vascular embolization is the primary approach for treating external carotid artery maxillary bleeding. Implantation of a covered stent can achieve hemostasis without altering hemodynamics.Conclusion: A comprehensive approach utilizing these methods can improve the success rate of treating nosebleeds following NPC radiotherapy.HighlightsThe mortality rate for carotid blowout following radiotherapy for NPC is high.Radiation therapy and tumor condition are correlated with epistaxis in NPC.Treatment methods for NPC-related epistaxis include posterior nostril tamponade, endoscopic hemostasis, DSA, selective vascular embolization, and stent implantation.The use of a covered stent for NPC-related carotid blowout achieves hemostasis without altering blood perfusion.Effective and timely application of various hemostasis methods is key to improving the success rate of rescue, considering the characteristics of NPC-related epistaxis.

    Abstract Liquid crystal elastomers (LCEs) have shown great potential as soft actuating materials in soft robots, with large actuation strain and fast response speed. However, to achieve the unique features of actuation, the liquid crystal mesogens should be well aligned and permanently fixed by polymer networks, limiting their practical applications. The recent progress in the 3D printing technologies of LCEs overcame the shortcomings in conventional processing techniques. In this study, the relationship between the 3D printing parameters and the actuation performance of LCEs is studied in detail. Furthermore, a type of inchworm-inspired crawling soft robot based on a liquid crystal elastomeric actuator is demonstrated, coupled with tilted fish-scale-like microstructures with anisotropic friction as the foot for moving forwards. In addition, the anisotropic friction of inclined scales with different angles is measured to demonstrate the performance of anisotropic friction. Lastly, the kinematic performance of the inchworm-inspired robot is tested on different surfaces.

    Abstract Abstract Background Little is known about the changes in allergen sensitization in China secondary to the environmental variations over the past decade. We aimed at investigating the variations in sensitization among asthma and/or rhinitis patients in China between 2008 and 2018. Methods This study analyzed cross‐sectional data from national surveys conducted in China in 2008 and 2018. After finishing the questionnaire, participants underwent serum specific IgE measurements. A total of 2322 and 2798 patients were enrolled in 2008 and 2018, respectively. The significance of differences in sensitization rates among four regions of China were assessed. Correlation analysis was used to identify the associations of sensitization with climate change and planting of Artemisia desertorum between the two surveys. Results Compared with 2008, the general sensitization rate to mites significantly increased in 2018, which ranked highest among all tested allergens. Sensitization to pollens, especially Artemisia vulgaris, showed the greatest increase in the north. The annual mean temperature, rainfall and relative humidity in all four regions, and the Artemisia desertorum coverage in the northeastern area, increased significantly in 2018 as compared with 2008. From 2008 to 2018, an increase in Dermatophagoides pteronyssinus sensitization was significantly associated with an increase in relative humidity (r = 0.54, p = 0.037). The increase in A. vulgaris sensitization was significantly associated with the increase in the A. desertorum planting area (r = 0.67, p = 0.006) and with a decrease in rainfall (r = −0.59, p = 0.021). Conclusions House dust mites remain the most important allergen in Chinese individuals with asthma and/or rhinitis. Pollen sensitization dramatically increased in northern China. Increases in sensitization to dust mites and Artemisia were related to the increases in humidity and planting area of A. desertorum.
