Purpose: The lncRNA TRG-AS1 and its co-expressed gene P2RY10 are important for colorectal cancer (CRC) occurrence and development. The purpose of our research was to explore the roles of TRG-AS1 and P2RY10 in CRC progression. Methods: The abundance of TRG-AS1 and P2RY10 was determined in CRC cell lines. LoVo cells were transfected with si-TRG-AS1 and si-P2RY10 constructs. Subsequently, the viability, colony formation, and migration of the transfected cells were analyzed using cell counting kit-8, clonogenicity, and scratch-wound/Transwell assays, respectively. Cells overexpressing GNA13 were used to further explore the relationship between TRG-AS1 and P2RY10 along with their downstream functions. Finally, nude mice were injected with different transfected cell types to observe tumor formation in vivo. Results: TRG-AS1 and P2RY10 were significantly upregulated in HT-29 and LoVo compared to FHC cells. TRG-AS1 knockdown and P2RY10 silencing suppressed the viability, colony formation, and migration of LoVo cells. TRG-AS1 knockdown downregulated the expression of P2RY10, GNA12, and GNA13, while P2RY10 silencing downregulated the expression of TRG-AS1, GNA12, and GNA13. Additionally, GNA13 overexpression reversed the cell growth and gene expression changes in LoVo cells induced by TRG-AS1 knockdown or P2RY10 silencing. In vivo experiments revealed that CRC tumor growth was suppressed by TRG-AS1 knockdown and P2RY10 silencing. Conclusions: TRG-AS1 knockdown repressed the growth of CRC cells by regulating P2RY10 and GNA13 expression, thereby controlling CRC occurrence and development.

This study aimed to investigate the therapeutic efficacy of programmed spatial anatomy of myopectineal orifice technique in laparoscopic total extraperitoneal hernioplasty (TEP) surgery. A total of 121 adult male patients with unilateral inguinal hernias who underwent TEP in the Department of General Surgery, Wujin Hospital, affiliated with Jiangsu University, from January 2019 to December 2020 were selected. Patients were divided into the procedural (63 cases) and traditional groups (58 cases) according to the surgical methods adopted. The procedural group underwent programmed spatial anatomy of the myopectineal orifice combined with TEP, and the traditional group underwent traditional TEP. The perioperative evaluation indicators and postoperative complications were observed and compared between the two groups. Compared with the traditional group, the time of handling hernia, the intraoperative operation time, intraoperative blood loss, postoperative ambulation time, and postoperative hospital stay in the procedural group were significantly reduced (P < 0.05). The incidence of postoperative complications such as sensory nerve abnormalities and chronic pain was significantly decreased (P < 0.05), and the total incidence of complications in the procedural group was significantly lower than that in the traditional group (P < 0.05). While there was no significant difference in postoperative incision infection (P > 0.05). The programmed spatial anatomy of the myopectineal orifice can significantly improve the treatment outcome of TEP, significantly improve the patients' intraoperative and postoperative indicators, and reduce the incidence of postoperative complications. It is worthy of being promoted among young physicians and basic hospitals.
