The nuclear transcription factor nuclear factor erythroid 2-related factor 2 (NRF2) plays a crucial role in maintaining cellular redox homeostasis. The aberrant NRF2 signaling confers enhanced antioxidant capacity, which is linked to tumor progression and therapeutic resistance. The current study investigates the biological effects and molecular mechanism of tribbles homolog 3 (TRIB3), a stress-induced protein, in regulating cell survival and apoptosis in lung cancer. This study first performed the RNA sequencing data analysis with 576 lung adenocarcinoma patients from the cancer genome atlas (TCGA) database. The NRF2- antioxidant response element (ARE) signature was enriched in patients with high TRIB3 expression. Dual-luciferase reporter assay and real-time quantitative polymerase chain reaction (PCR) were used to confirm the effect of TRIB3 on the kelch-like ECH-associated protein-1 (KEAP1)-NRF2 pathway.

Objective To investigate the therapeutic effect of argon-helium cryoablation combined with transcatheter arterial chemoembolization (TACE) for primary hepatocellular carcinoma (HCC) and its influence on vascular endothelial growth factor (VEGF) level, and to compare it with simple TACE treatment. Methods During the period from Aug. 2013 to Aug. 2014 a total of 50 patients with primary HCC were admitted to Hunan Provincial People’s Hospital. The patients were randomly and equally divided into group A (TACE group, n=25) and group B (argon-helium cryoablation+TACE group, n=25). VEGF levels in the peripheral blood were determined before and after the treatment, and the results were statistically compared between the two groups. Results After the treatment the VEGF level in group A was significantly increased when compared with preoperative VEGF level (P<0.05). In group B, the VEGF level was decreased after the treatment, which was statistically significant lower than the preoperative VEGF level (P<0.05). The differences in VEGF level between the two groups were statistically significant (P<0.05). Conclusion The statistic analysis of VEGF levels indicates that argon-helium cryoablation combined with TACE is probably superior to simple TACE in the inhibition of tumor angiogenesis.

Objective To compare 99Tcm-MIBI MPI with delayed enhancement MRI (DE-MRI) in patients with idiopathic dilated cardiomyopathy (IDCM). Methods Forty patients with IDCM were included. They underwent both rest 99Tcm-MIBI myocardial perfusion imaging and DE-MRI within 7 days. 99Tcm-MIBI MPI was performed to identify diffuse or segmental abnormal perfusion patterns including reduced or defect perfusion segments. DE-MRI images were divided into 4 categories: no delayed enhancement, septal, subendocardial and transmural delayed enhancement, x2 test was used for data analysis. Results Diffuse and segmental perfusion abnormality on 99Tcm-MIBI MPI were found in 19 (47.5%) and 21 (52.5%)patients respectively, while DE-MRI enhancement was simultaneously found in 5 patients of the former (5/19, 26.3%) and 18 (18/21, 85.7%) of the latter (x2 =14.401, P<0. 001). For those (n=18) with both segmental perfusion abnormality and DE-MRI enhancement, the number of segments of the 4 DE-MRI respectively. A significant difference was found in the DE-MRI enhancement categories between normal and defect perfusion segments (x2 = 29. 183, P <0.001 ) and between reduced and defect perfusion segments as well (x2 =25. 110, P<0. 001). Conclusions Both diffuse and segmental perfusion abnormalities on 99Tcm-MIBI MPI can be found in patients with IDCM. DE-MRI enhancement is more frequently found in patients with segmental perfusion abnormality.

OBJECTIVETo assess the clinical value of digitalized minimally invasive technique in the treatment of the hepatolithiasis.
METHODSThe 64-slice spiral CT data were acquired from 4 hepatolithiasis patients for three-dimensional reconstruction and simulation operation using abdominal medical image-3D visualization system (MI-3DVS). Three-dimensional reconstruction was performed for the liver, hepatic arteries, hepatic veins, portal veins, intrahepatic bile ducts and calculi. Based on the size and position of the calculi and the distribution of the dilated or stenotic biliary ducts, several simulation operations such as partial hepatectomy and hepaticojejunstomy were performed. With guidance by the findings in the simulation operation, the actual minimally invasive operation was performed.
RESULTSThe three-dimensional models of the liver, hepatic arteries, hepatic veins, portal veins, intrahepatic bile ducts and calculi were reconstructed successfully, which clearly visualized the site and the number of calculi and the condition of the involved intrahepatic bile ducts. Guided by the three-dimensional models and the simulation operations, partial hepatectomy and hepaticojejunstomy were performed and the calculi were removed completely in all the 4 cases with maximum preservation of the residual liver volume.
CONCLUSIONThree-dimensional reconstruction and simulation operation allows digital minimally invasive treatment of hepatolithiasis, which can be a new approach to hepatobiliary surgery.
