Objective:
The treatment of asymmetric maxillary hypoplasia and dental crowding secondary to unilateral cleft lip and palate (UCLP) is often challenging.This study introduced an asymmetric tooth-borne distractor in anterior maxillary segmental distraction osteogenesis and used three-dimensional finite element analysis to evaluate its potential for clinical application in cases of asymmetrical maxillary hypoplasia.
Methods:
A cone-beam computed tomography scan of a late adolescent with UCLP was used to construct a three-dimensional finite element model of the teeth and maxillary structures. An asymmetric distractor model was used to simulate conventional distraction osteogenesis and asymmetric distraction osteogenesis (ADO) to evaluate the resultant stress distribution and displacement.
Results:
Postoperatively, both distraction methods resulted in anterior maxillary segment advancement with a slight upward movement. ADO yielded a greater increase in the dental arch length on the cleft side and induced rotation of the anterior maxillary segment, potentially improving midline deviation. Both methods showed similar stress distributions, with higher stress concentrations on the cleft side.
Conclusions
ADO may offer clinical advantages in correcting asymmetrical maxillary hypoplasia in patients with UCLP by facilitating asymmetrical expansion and rotation of the maxilla. Further research is needed to generalize these findings to other clinical presentations.

Purpose:
The genomic characteristics of uterine sarcomas have not been fully elucidated. This study aimed to explore the genomic landscape of the uterine sarcomas (USs).
Materials and Methods:
Comprehensive genomic analysis through RNA-sequencing was conducted. Gene fusion, differentially expressed genes (DEGs), signaling pathway enrichment, immune cell infiltration, and prognosis were analyzed. A deep learning model was constructed to predict the survival of US patients.
Results:
A total of 71 US samples were examined, including 47 endometrial stromal sarcomas (ESS), 18 uterine leiomyosarcomas (uLMS), three adenosarcomas, two carcinosarcomas, and one uterine tumor resembling an ovarian sex-cord tumor. ESS (including high-grade ESS [HGESS] and low-grade ESS [LGESS]) and uLMS showed distinct gene fusion signatures; a novel gene fusion site, MRPS18A–PDC-AS1 could be a potential diagnostic marker for the pathology differential diagnosis of uLMS and ESS; 797 and 477 uterine sarcoma DEGs (uDEGs) were identified in the ESS vs. uLMS and HGESS vs. LGESS groups, respectively. The uDEGs were enriched in multiple pathways. Fifteen genes including LAMB4 were confirmed with prognostic value in USs; immune infiltration analysis revealed the prognositic value of myeloid dendritic cells, plasmacytoid dendritic cells, natural killer cells, macrophage M1, monocytes and hematopoietic stem cells in USs; the deep learning model named Max-Mean Non-Local multi-instance learning (MMN-MIL) showed satisfactory performance in predicting the survival of US patients, with the area under the receiver operating curve curve reached 0.909 and accuracy achieved 0.804.
Conclusion
USs harbored distinct gene fusion characteristics and gene expression features between HGESS, LGESS, and uLMS. The MMN-MIL model could effectively predict the survival of US patients.

Objective:To construct a communication strategy and implementation method for advanced cancer patients based on two communication models widely used at home and abroad, so as to reduce the difficulty of clinical disease notification.Methods:From January to October 2022, based on the communication model of SPIKES (Setting, Perception, Invitation, Knowledge, Empathy, Summary) and NURSE(Name, Understand, Respect, Support, Explore), combined with literature analysis, qualitative interviews, and expert argumentation, the communication strategy items of advanced cancer patients were constructed.Results:A total of 18 articles were included in the literature analysis. Qualitative interviews were conducted with 20 interviewees (including 4 doctors, 11 nurses, and 5 patients),6 males, 14 females, aged (35.94 ± 8.03) years old. A total of 8 experts participated in the demonstration, 2 males and 6 females, aged (41.88 ± 6.58) years old. Finally, the specific items and words of the disease notification process and communication strategies of advanced cancer patients in line with China ′s clinical practice were constructed. A total of 3 first-level items, 16 second-level items, 53 third-level items, and speech techniques were constructed, including pre-communication preparation, regular communication strategies, and poor communication disposal strategies. The importance score of the item was 4.50 to 5.00, and the coefficient of variation of the item was 0 to 0.12. Conclusions:The communication strategy of advanced cancer patients based on the communication model is scientific and feasible, and can be used as a tool to inform advanced cancer patients.
