Objective To explore the correlation of Gli1 expression with clinical characteristics and prognosis of liver cancer. Methods Such Databases as PubMed, Embase, CNKI, Wanfang Database and Chinese Biomedical Literature Database were searched to collect cohort studies, which has published on the correlation between the expression of Gli1 and the clinical pathologic features of liver cancer and its prognostic value from the establishment of the databases to December 2016. Results Twelve studies with a total of 831 patients were included in this study. The high expression of Gli1 was associated with the tumor diameter >5 cm [relative risk (RR)=1.39, 95% confidence interval (CI) (1.08, 1.79)], clinical stage [RR=1.26, 95%CI (1.05, 1.51)], intrahepatic metastasis [RR=1.39, 95%CI (1.06, 1.83)] and venous invasion [RR=1.44, 95%CI (1.01, 2.04)], but the correlation of Gli1 expression was not significant with gender, histological differentiation, tumor diameter >3 cm, hepatitis B virus, cirrhosis and alpha fetoprotein. Meanwhile, the results of Meta-analysis showed that the higher Gli1 expression in liver cancer patients had a worse 3-/5-year overall survival rate and overall survival rate than those of the lower Gli1 expression group [3-year, RR=3.38, 95%CI (2.01, 5.67); 5-year, RR=1.51, 95%CI (1.19, 1.91); overall survival, RR=1.60, 95%CI (1.11, 2.30)]. And the higher Gli1 expression in liver cancer patients had a worse disease free survival rate than that in the lower Gli1 expression group [RR=1.89, 95%CI (1.35, 2.66)]. Conclusion The high expression of Gli1 is associated with poor prognostic outcome in liver cancer, and may be used as an important prognostic marker for patients with liver cancer.
ObjectiveTo compare the diagnostic accuracy of supraspinatus muscle outlet X-ray film, oblique sagittal multislice computed tomography (MSCT), and oblique sagittal MRI in the diagnosis of subacromial impingement syndrome (SIS). Methods A retrospective analysis was conducted on the imaging data of 106 patients diagnosed with SIS between January 2023 and December 2024. The cohort consisted of 32 males and 74 females, with ages ranging from 43 to 70 years (mean, 60.19 years). All patients underwent supraspinatus outlet X-ray film, MSCT, and MRI scans, with MSCT further subjected to three-dimensional reconstruction. Two experienced radiologists independently evaluated the acromion morphology in each imaging modality using the Bigliani classification system. Inter-observer reliability was assessed via Kappa statistics. The CT three-dimensional reconstructions were used as the “gold standard”. The overall consistency, Kappa values, sensitivity, and specificity of the three imaging modalities were calculated. Receiver operating characteristic (ROC) curves were plotted, and the area under the curve (AUC) was computed. Results The inter-observer reliability for supraspinatus outlet X-ray film, oblique sagittal MSCT, and oblique sagittal MRI was moderate, with Kappa values of 0.62, 0.63, and 0.55, respectively. When compared to the CT three-dimensional reconstructions as the “gold standard”, the overall consistency was 88.7% (94/106), 62.3% (66/106), and 58.5% (62/106), respectively. The supraspinatus outlet X-ray film showed excellent consistency (Kappa=0.77), whereas the consistency of MSCT and MRI was lower (Kappa=0.34 and 0.29, respectively). In terms of diagnostic sensitivity and specificity, the supraspinatus outlet X-ray film outperformed oblique sagittal MSCT and oblique sagittal MRI in distinguishing various acromion types. ROC analysis demonstrated that the AUC for the supraspinatus outlet X-ray film was consistently higher than for oblique sagittal MSCT and oblique sagittal MRI, with the highest diagnostic performance observed for type Ⅲ hooked acromion (AUC=0.939). Conclusion Supraspinatus outlet X-ray film provides the highest diagnostic accuracy for acromion classification in SIS patients, particularly in identifying type Ⅲ hooked acromion, which is strongly associated with SIS. Given its superior sensitivity and consistency, it should be considered the primary screening tool. MSCT and MRI serve as valuable supplementary modalities for complex cases and preoperative evaluation.
