Good prognosis was defined as a Modified Rankin Scale (mRS) score of 0-3 and poor prognosis mRS score of 4-6 at 90 day follow-up, and factors related to prognosis were analyzed.Results: Among the 77 patients included in the analysis, 68 patients (88.3%) achieved recanalization (modified thrombolysis in cerebral infarction, mTICI 2b/3 grade). Thirty eight patients (49.4%) achieved an overall good prognosis. In univariate analysis, age, baseline Glasgow Coma Scale (GCS), baseline National Institutes of Health Stroke Scale (NIHSS), posterior circulation Acute Stroke Prognostic Early CT score (pc ASPECTS), preoperative intravenous thrombolysis, and mTICI2b-3 were factors affecting good prognosis. Multivariate analysis showed that shorter onset to puncture time (OR 0.069; 95% CI, 0.009-0.519; p = 0.009), lower NIHSS (OR 1.179; 95% CI, 1.019-1.364; p = 0.027), and higher pc ASPECTS (OR 0.489, 95% CI, 0.250-0.959, p = 0.037) were factors influencing good prognosis in this study.Conclusions: In summary, endovascular treatment for patients with acute basilar artery occlusion is safe and effective, but EVT may achieve better prognosis within 6 h of onset. The shorter time from onset to puncture at admission, lower baseline NIHSS score, and higher baseline pc-ASPECTS are factors affecting the good prognosis of patients at 90 days.","PeriodicalId":16200,"journal":{"name":"Journal of Investigative Surgery","volume":"38 1","pages":"2442382"},"PeriodicalIF":2.1,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142932051","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}

GPR27 expression was assessed using reverse transcription-polymerase chain reaction (RT-PCR) and immunohistochemistry.Results: Database analysis and RT-PCR revealed over-expression of GPR27 mRNA in ovarian cancer tissues compared to normal ovarian tissues. Ovarian cancer patients with up-regulated GPR27 transcription were associated with better overall survival and disease-free survival compared to those with downregulated GPR27 mRNA in the TCGA dataset and Kaplan-Meier plot database (N = 1656). GPR27 demonstrated good predictive value for pathological response in patients with ovarian cancer receiving platinum-based therapy. The predictive performance for 6-month relapse-free survival was higher in endometrioid ovarian cancer (AUC:0.804) than that in serous ovarian cancer. GPR27 protein levels were significantly up-regulated in ovarian cancer tissues compared with normal ovarian tissue, and high GPR27 protein expression correlated with early-stage TNM. ROC analysis revealed that the GPR27 protein, quantified by the immunohistochemistry score, effectively predicted the response to platinum-based therapy response with an AUC of 0.7479 in our cohort.Conclusion: GPR27 was up-regulated in ovarian cancer, compared with that of normal ovarian tissue, and was strongly correlated with survival outcomes and response to platinum-based therapy.

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).

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}

Patient demographics, surgical data and postoperative outcomes were retrieved from the medical records.Results: All operations were successfully completed laparoscopically, and with a median follow-up of 65 months, the overall symptom score was significantly reduced from 32 to 8 (p < 0.0001) and the BMI was increased from 17.2 kg/m2 to 21.8 kg/m2 (p < 0.0001).Conclusions: When conservative measures failed in the treatment of SMAS, laparoscopic surgery proved to be a safe and effective method. The specific surgical technique was selected according to the history and symptoms of each individual patient. To our knowledge, this study represents the largest number of laparoscopic procedures at a single center for the treatment of superior mesenteric artery syndrome.","PeriodicalId":16200,"journal":{"name":"Journal of Investigative Surgery","volume":"37 1","pages":"2387524"},"PeriodicalIF":2.1,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142080540","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}
