The lncRNA LINC-PINT has garnered attention for its latent role in enhancing fracture healing, but its specific functions in this process remain unclear.Objectives: The primary objective of this study is to investigate the clinical relevance and underlying molecular mechanisms of LINC-PINT in delayed fracture healing (DFH), while also assessing its potential as an early diagnostic biomarker.Materials and methods: The expression levels of LINC-PINT were measured in the serum of DFH patients and those with normal fracture healing using RT-qPCR. In MC3T3-E1 cells, the study investigated the influence on the expression of differentiation-related protein, cell viability, and apoptosis through the modulation of LINC-PINT and miR-324-3p. To elucidate the targeting relationship between LINC-PINT, miR-324-3p, and BMP2, a dual-luciferase reporter assay was employed.Results: The findings revealed a significant downregulation of LINC-PINT expression in DFH patients. LINC-PINT showed high sensitivity and specificity as a diagnostic marker for DFH. In MC3T3-E1 cells, LINC-PINT overexpression markedly enhanced the expression levels of ALP, OCN, Runx2, and OPN, improved cell viability, and inhibited apoptosis. LINC-PINT negatively regulated miR-324-3p, and the effects of LINC-PINT were counteracted by miR-324-3p. LINC-PINT was found to regulate BMP2 by targeting miR-324-3p.Conclusion: LINC-PINT could serve as an early diagnostic biomarker for DFH and slow the progression of DFH by modulating BMP2 through the targeted regulation of miR-324-3p.

The optimal cutoff value of BMR (BMR ≤1149 kcal/day) was obtained using the X-tile plot. Logistic and Cox regression analyses were then performed to evaluate the relevant influencing factors of clinical outcomes. Finally, R software was utilized to construct the nomogram.Results: A total of 213 patients were defined as having a lower basal metabolic rate (LBMR). Univariate and multivariate analyses showed that gastric cancer patients with LBMR were more prone to postoperative complications and had poor long-term overall survival (OS). The established nomogram had good predictive power to assess the risk of OS in gastric cancer patients after radical gastrectomy (c-index was 0.764).Conclusions: Overall, LBMR on admission is associated with the occurrence of postoperative complications in gastric cancer patients, and this population has a poorer long-term survival.

The surgical technique was based on the description performed by Levitt et al. (2013, J Pediatr Surg. 2013;48(11):2289-2295). Information related to the surgical procedures and the clinical evolution in the postoperative period were recorded and analyzed. There were no deaths or severe complications. The anesthetic and the surgical times were significantly higher for the first three animals of the experiment. Our animal model proved adequate to perform the transanal endorectal Swenson pull-through technique, allowing the training of surgical skills through a model similar to the human, with few anesthetic complications and good postoperative evolution, including postoperative follow-up.

The clinicopathological characteristics including tumor size, depth of stromal invasion, presence of lymphovascular space invasion (LVSI), infiltration into vagina or uterine body, status of surgical vaginal margin, parametrial involvement, and pelvic or para-aortic lymph nodes metastasis were compared between the CC patients with/without coexisting adenomyosis by Student's t-tests, chi-square or Fisher's exact tests. The Cox proportional hazards model was employed to evaluate potential risk factors. Survival curves were constructed using the Kaplan-Meier method.Results: Among the cervical cancer cohort, the coexistence of adenomyosis is associated with a lower likelihood of deep stromal invasion (50.2% vs 54.6%, p < 0.0001) and vaginal infiltration (25.8% vs 29.1%, p = 0.041) compared with CC patients without adenomyosis. There were no significant differences in tumor size, presence of LVSI, uterine body infiltration, status of surgical vaginal margin, parametrial involvement, and pelvic or para-aortic lymph nodes metastasis between both groups.

Nonetheless, acute injury and inhibited regeneration of the intestinal epithelium occur commonly in critically ill surgical patients, leading to the translocation of luminal toxic substances and bacteria to the bloodstream. Effective therapies for the preservation of intestinal epithelial integrity and for the prevention of mucosal hemorrhage and gut barrier dysfunction are limited, primarily because of a poor understanding of the mechanisms underlying mucosal disruption. Noncoding RNAs (ncRNAs), which include microRNAs (miRNAs), long ncRNAs (lncRNAs), circular RNAs (circRNAs), and small vault RNAs (vtRNAs), modulate a wide array of biological functions and have been identified as orchestrators of intestinal epithelial homeostasis. Here, we feature the roles of many important ncRNAs in controlling intestinal mucosal growth, barrier function, and repair after injury-particularly in the context of postoperative recovery from bowel surgery. We review recent literature surrounding the relationships between lncRNAs, microRNAs, and RNA-binding proteins and how their interactions impact cell survival, proliferation, migration, and cell-to-cell interactions in the intestinal epithelium. With advancing knowledge of ncRNA biology and growing recognition of the importance of ncRNAs in maintaining the intestinal epithelial integrity, ncRNAs provide novel therapeutic targets for treatments to preserve the gut epithelium in individuals suffering from critical surgical disorders.","PeriodicalId":16200,"journal":{"name":"Journal of Investigative Surgery","volume":"37 1","pages":"2308809"},"PeriodicalIF":1.9,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11027105/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139697587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

OS and RCSS after radiation, chemotherapy, and surgery were investigated using the Kaplan-Meier approach. Fourteen factors, including gender, age, race, and others, were subjected to univariate and multivariate COX analyses. Predicting RCSS at three, five, or ten years is the main goal. Predicting OS at three, five, or ten years is the secondary endpoint. Cox analyses, both univariate and multivariate, were used to identify prognostic factors. Furthermore, a nomogram was developed to precisely forecast patient survival rates at 3-, 5-, and 10-year intervals. DCA, calibration curves, and ROC were used to assess the nomogram's efficacy.Results: Kaplan-Meier analysis revealed that PN was associated with better survival compared to RN for tumors ≤10 cm. Cox analysis identified 10 independent prognostic factors. These variables included gender, age, race, histological type, histological grade, AJCC stage, N stage, T stage, M stage, and surgical type. Based on these variables, a nomogram for OS and RCSS prediction was created.Conclusion: PN is advised over RN for RCC patients whose tumors are less than 10 cm in diameter since it offers more advantages. The combined nomogram model, which is based on clinicopathological characteristics, therapy data, and demographic variables, may be used to predict the survival of RCC patients and perform prognostic and survival analysis with accuracy.","PeriodicalId":16200,"journal":{"name":"Journal of Investigative Surgery","volume":"37 1","pages":"2435045"},"PeriodicalIF":2.1,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142818311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
