MIVAT appears to be safe and feasible in patients with benign thyroid nodules, with minimal injury and excellent cosmetic results. Furthermore, after properly lengthening the skin incision, MIVAT can be used for patients with large benign thyroid nodules or even early-stage differentiated thyroid carcinoma.

Cervical adenocarcinoma (CA) is a type of cervical cancer, and in previous decades its incidence has steadily increased. The upregulation of regucalcin (RGN) in various tumor cell types inhibits the progression of cancer. To understand the role of RGN in CA, RGN expression in human cervical cancer compared with normal tissues was analyzed using The Cancer Genome Atlas database (TCGA). Subsequently, transfection of lentivirus-mediated RGN into HeLa cells was conducted to study its function in tumor proliferation and metastasis. The expression of RGN and proteins associated with the Wnt/β-catenin signaling pathway and epithelial-mesenchymal transition (EMT) were determined using reverse transcription-quantitative polymerase chain reaction and western blotting. Cell migration and invasion were evaluated using Transwell assays. Furthermore, cell proliferation, colony formation and cell cycle were assessed using the Cell Counting Kit-8, colony formation assay and flow cytometry, respectively. Lentivirus-mediated RGN effectively upregulated RGN expression, inhibited cell proliferation, retarded cellular invasion and promoted cell cycle arrest at the G 2 /M phase in HeLa cells. In addition, the expression levels of β-catenin, p-glycogen synthase kinase (GSK)-3β, matrix metalloproteinase (MMP)-3, MMP-7 and MMP-9 were effectively decreased, whilst those of E-cadherin and GSK-3β were increased. The results suggest that RGN may be an inhibitory factor in tumorigenesis, and its mechanism of inhibiting tumor proliferation and metastasis may be associated with Wnt/β-catenin signaling and EMT.

BackgroundSerum gamma-glutamyltransferase (GGT) has been reported to be correlated with survival in a variety of malignancies. However, its effect on patients with bladder cancer (BC) treated by radical cystectomy has never been evaluated.Patients and MethodsWe retrospectively evaluated 263 patients who underwent radical surgery in our center. Baseline features, hematologic variables, and follow-up data were obtained. The endpoints included overall survival (OS), cancer-specific survival (CSS), and disease-free survival (DFS). The relationship between GGT and survival were evaluated.ResultsThe median follow-up period for all patients was 34.7 (22.9-45.9) months. At the last follow-up, 67 patients died, 51 patients died of cancer, 92 patients experienced disease recurrence. Patients with an elevated serum GGT had a higher rate of pT3-T4 tumors. Patients with a higher preoperative serum GGT had a lower rate of OS, CSS and DFS (P < 0.001 for all). Multivariate analysis identified that preoperative serum GGT was independent predictor of OS (HR: 3.027, 95% CI: 1.716-5.338; P < 0.001), CSS (HR: 2.115, 95% CI: 1.093-4.090; P = 0.026), DFS (HR: 2.584, 95% CI: 1.569-4.255; P < 0.001). Age, diabetes history, pathologic T stage, and lymph node status also were independent predictors of prognosis for BC patients.ConclusionsOur results indicated that preoperative serum GGT was an independent prognosis predictor for survival of BC patients after radical cystectomy, and can be included in the prognostic models.

Aim: To construct and rescue a recombinant Newcastle disease virus that can express IP10 protein and evaluate its targeted killing effect on liver cancer in vivo and in vitro. Materials & methods: Fluorescence quantitative PCR, western blot and ELISA were used to detect the expression and secretion of IP10 in cells. The H22 mouse liver cancer cells were used to establish subcutaneous tumor-bearing mice experimental animal tumor models, and the tumor growth of mice in each group was observed while receiving treatment with rLasota. Results: The recombinant Newcastle disease virus was successfully constructed and can kill tumor cells successfully. Conclusion: The rLasota-IP10-IRES-EGFP achieves antitumor effects by killing hepatocellular carcinoma cells, enhancing T-lymphocyte infiltration in tumor tissues and inhibiting neovascularization.
