Clinical data were collected and NLR and PLR were assessed. Receiver operating characteristic (ROC) curve analysis was conducted to assess the predictive value of NLR and PLR for PHI occurrence in TBI patients. Logistic regression analysis was performed to identify risk factors influencing PHI development and poor neurological prognosis.Results: The PHI group (n = 77) exhibited significantly higher NLR and PLR ratios than the non-PHI group (n = 89). Independent risk factors for PHI occurrence included higher Abbreviated Injury Scale scores, absent pupillary reflexes, lower Glasgow Coma Scale (GCS) scores, and elevated NLR and PLR ratios. The combined use of NLR and PLR ratios demonstrated superior predictive performance for PHI occurrence, with a higher area under the curve (AUC: 0.843) and sensitivity (77.9%, cutoff values: 17.19 for NLR and 196.33 for PLR) compared to NLR alone (AUC: 0.794, sensitivity: 53.2%, cutoff value: 21.78) or PLR alone (AUC: 0.665, sensitivity: 53.2%, cutoff value: 235.48). For poor neurological prognosis, higher AIS scores, lower GCS scores, and elevated NLR ratios were identified as independent risk factors.Conclusion: TBI patients with elevated NLR and PLR ratios are at increased risk of developing PHI. In severe TBI cases, patients with high NLR ratios during the early stages tend to experience poor neurological outcomes.","PeriodicalId":16200,"journal":{"name":"Journal of Investigative Surgery","volume":"38 1","pages":"2470453"},"PeriodicalIF":2.1,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143692650","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}

This study aimed to investigate the role and underlying mechanism of the long non-coding X inactivation-specific transcript (lncRNA XIST)/microRNA-329-3p (miR-329-3p)/transmembrane BAX Inhibitor Motif-6 (TMBIM6) axis in the proliferation, migration, and invasion of NSCLC, and its potential as a therapeutic target.Methods: The expression levels of XIST, miR-329-3p, and TMBIM6 in NSCLC tissues and cell lines were assessed using quantitative real-time PCR (qRT-PCR), and their correlations with clinicopathological characteristics were examined. Dual-luciferase reporter assays and RNA immunoprecipitation (RIP) were used to validate the binding interactions among XIST and miR-329-3p, and TMBIM6. The malignant phenotypes of NSCLC cells, including proliferation, migration, invasion, and apoptosis, were assessed using CCK-8, Transwell assays, and flow cytometry.Results: Silencing XIST significantly suppressed the proliferation, migration, and invasion of NSCLC cells while promoting apoptosis. Mechanistically, XIST functioned as a competitive endogenous RNA (ceRNA), sponging miR-329-3p and thereby downregulating its expression. Overexpression of miR-329-3p counteracted the oncogenic effects of XIST in NSCLC cells. Additionally, miR-329-3p downregulated TMBIM6 expression, while TMBIM6 overexpression counteracted the tumor-suppressive effects of miR-329-3p.Conclusion: Silencing XIST upregulates miR-329-3p, leading to the suppression of TMBIM6 expression and inhibition of NSCLC progression. These findings suggest that the XIST/miR-329-3p/TMBIM6 axis could serve as a promising molecular target for therapeutic strategies in NSCLC.","PeriodicalId":16200,"journal":{"name":"Journal of Investigative Surgery","volume":"38 1","pages":"2457472"},"PeriodicalIF":2.1,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143414451","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}

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.

The aim of this study was to explore the association between basal metabolic rate (BMR) and postoperative clinical outcomes in gastric cancer patients.Methods: We collected data of 958 gastric cancer patients admitted at our center from June 2014 to December 2018. 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. Therefore, there should be more focus on the perioperative management of patients with this risk factor before surgery.","PeriodicalId":16200,"journal":{"name":"Journal of Investigative Surgery","volume":"37 1","pages":"2350358"},"PeriodicalIF":1.9,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140898083","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}
