Alveolar soft part sarcoma (ASPS) is a rare mesenchymal tumor characterized by rearrangement of the ASPSCR1 and TFE3 genes and a histologically distinctive pseudoalveolar pattern. ASPS progresses slowly, but is prone to late metastasis. As ASPS is refractory to conventional chemotherapy, the only curative treatment is complete surgical resection. The prognosis of advanced and metastatic cases is poor, highlighting the need for preclinical research to develop appropriate treatment options. However, ASPS is extremely rare, accounting for < 1% of all soft tissue sarcomas, and only one patient-derived ASPS cell line is available from public cell banks worldwide for research. This study reports the establishment of a novel ASPS cell line derived from the primary tumor tissue of an ASPS patient, named NCC-ASPS2-C1. This cell line retains the ASPSCR1-TFE3 fusion gene, which is characteristic of ASPS. The characterization of this cell line revealed stable growth, spheroid formation, and invasive properties. By screening a drug library using NCC-ASPS2-C1, we identified several drugs that inhibited the proliferation of ASPS cells. In conclusion, the establishment of NCC-ASPS2-C1 provides a valuable resource for advancing ASPS research and developing novel treatments for this challenging disease.

BACKGROUND This study included 32 patients with single missing teeth and alveolar bone defects and aimed to compare outcomes from guided bone regeneration with a gelatin/polylactic acid (GT/PLA) barrier membrane and a Guidor® bioresorbable matrix barrier dental membrane. MATERIAL AND METHODS A total of 32 participants were recruited in the clinical study, with single missing teeth and alveolar bone defects, requiring guided bone regeneration (32 missing teeth in total). They were randomly divided into the GT/PLA membrane group (experimental) and Guidor® membrane group (control) by the envelope method (n=16).

Objective: To study the biomechanical changes induced by differences in perioral force in patients with missing anterior maxillary teeth at rest via finite element analysis (FEA).
Methods: Using conical beam CT (CBCT) images of a healthy person, models of the complete maxillary anterior dental region (Model A) and maxillary anterior dental region with a missing left maxillary central incisor (Model B) were constructed. The labial and palatine alveolar bone and tooth surface of the bilateral incisor and cusp regions were selected as the application sites, the resting perioral force was applied perpendicular to the tissue surface, and the changes in maxillary stress and displacement after the perioral force was simulated were analyzed.

Objectives: The aim of this study was evaluate the effect of Platelet-Rich Fibrin (PRF) in patients after mandibular third molar extraction through an analysis of the most current literature on systematic reviews and meta-analyses.
Data, Sources And Study Selection: By using computer-assisted search technology, we comprehensively searched several reliable databases, such as China National Knowledge Infrastructure (CNKI), WanFang Data, the Chinese biomedical literature database, PubMed, Web of Science, EMBase, and the Cochrane Library, and performed a systematic retrospective meta-analysis on all of the collected studies on the therapeutic effects of PRF on patients after mandibular third molar extraction. A total of nine meta-analyses were performed in this study, and all nine studies were rated as high quality on the basis of the AMSTAR 2 criteria.

The present study was a retrospective single-center study. A total of 81 patients diagnosed with metastatic soft tissue sarcoma were included who received pazopanib therapy. Clinical data, including age at diagnosis, histological subtype, treatments received before pazopanib, number of metastatic sites at the time of initiation of treatment, progression-free survival and overall survival time under pazopanib treatment, side effects and response evaluation in follow-up imaging after initiation of pazopanib therapy, were recorded.
