With high hardness, high thermal and chemical stability and excellent optical performance, hard materials exhibit great potential applications in various fields, especially in harsh conditions. Femtosecond laser ablation has the capability to fabricate three-dimensional micro/nanostructures in hard materials. However, the low efficiency, low precision and high surface roughness are the main stumbling blocks for femtosecond laser processing of hard materials. So far, etching- assisted femtosecond laser modification has demonstrated to be the efficient strategy to solve the above problems when processing hard materials, including wet etching and dry etching. In this review, femtosecond laser modification that would influence the etching selectivity is introduced. The fundamental and recent applications of the two kinds of etching assisted femtosecond laser modification technologies are summarized. In addition, the challenges and application prospects of these technologies are discussed. 展开更多

BACKGROUND Castleman disease, also known as giant lymph node hyperplasia, was first reported in 1956. It is a rare benign proliferative pathological change of the lymph nodes.CASE SUMMARY The patient, a 33-year-old woman, had epigastric distension for half a year.Examinations were performed in a local hospital. Computed tomography scan showed round soft tissue nodules, about 5.45 cm in diameter, in the hepaticgastric space. Endoscopic ultrasound and endoscopic ultrasound guided fine needle aspiration was performed on the patient. Rapid on-site evaluation,hematoxylin eosin staining and histopathology of the puncture smear was performed. According to the Diff-Quik staining and hematoxylin eosin staining results of preoperative endoscopic ultrasound guided fine needle aspiration puncture smears as well as the immunohistochemistry results, Castleman disease was highly suspected. A sufficient preoperative evaluation was made, and a precise surgical plan was developed. Postoperative pathology confirmed Castleman disease.CONCLUSION Endoscopic ultrasound guided fine needle aspiration can extract internal tissues of the tumor for histological and cytological examinations and provide accurate diagnosis as much as possible. Therefore, a sufficient preoperative evaluation can be made, and a precise surgical plan can be developed. 展开更多
