Quantitative analysis for detection and grading of hepatocellular carcinoma: Comparison of diffusion kurtosis imaging, intravoxel incoherent motion and conventional diffusion-weighted imaging.

The aim of the present study was to compare the diagnostic performance of the main parameters derived from diffusion kurtosis imaging (DKI), intravoxel incoherent motion (IVIM) and diffusion-weighted imaging (DWI) regarding the detection and grading of hepatocellular carcinoma (HCC). A total of 78 patients diagnosed with HCC by biopsy were prospectively enrolled in the present study, and underwent routine magnetic resonance imaging (MRI), DWI, IVIM, DKI and contrast-enhanced MRI prior to surgery. Measurements, including mean diffusivity (MD), mean diffusional kurtosis (MK), true diffusion coefficient (D), pseudo-diffusion coefficient (D*), perfusion fraction (f) and apparent diffusion coefficient (ADC), were compared with grading HCC using one-way ANOVA followed by the Student-Neuman-Keuls-q post-hoc test.

Microwave ablation vs. cryoablation for treatment of primary and metastatic pulmonary malignant tumors.

At present, minimally invasive surgery is one of the primary strategies for the treatment of malignant pulmonary tumors. Although, there are some comparative studies between microwave ablation and radiofrequency for the treatment of malignant pulmonary tumors, there are few studies that have investigated the comparison between microwave ablation and cryoablation. The aim of the study was to retrospectively compare the efficacy and complications of microwave ablation (MWA) and cryoablation in the treatment of malignant pulmonary tumors.

High resolution computed tomography for the diagnosis of 2019 novel coronavirus (2019-nCoV) pneumonia: a study from multiple medical centers in western China.

Background: To evaluate the role of high-resolution computed tomography (HRCT) in the diagnosis of 2019 novel coronavirus (2019-nCoV) pneumonia and to provide experience in the early detection and diagnosis of 2019-nCoV pneumonia.

Methods: Seventy-two patients confirmed to be infected with 2019-nCoV from multiple medical centers in western China were retrospectively analyzed, including epidemiologic characteristics, clinical manifestations, laboratory findings and HRCT chest features.

Results: All patients had lung parenchymal abnormalities on HRCT scans, which were mostly multifocal in both lungs and asymmetric in all patients, and were mostly in the peripheral or subpleural lung regions in 52 patients (72.

SOCS3 Is Upregulated and Targeted by miR30a-5p in Allergic Rhinitis.

Background: Suppressor of cytokine signaling 1 (SOCS1) and SOCS3 play important roles in T helper cell differentiation, which is involved with the pathologic mechanisms of allergic rhinitis (AR). The aim of this study was to evaluate the expression of SOCS1 and SOCS3 in AR and find their regulatory microRNAs (miRNAs) to provide a basis for the treatment of AR.

Methods: The expression of SOCS1 and SOCS3 were analyzed by real-time PCR, immunohistochemistry, and Western blot.

Down-regulation of miR-129-5p inhibits growth and induces apoptosis in laryngeal squamous cell carcinoma by targeting APC.

miRNAs regulate gene expression and are key mediators of tumourigenesis. miR-129 has diverse effects in tumours, but its role in laryngeal squamous cell carcinoma (LSCC) remains unknown. This article focuses on the role of miR-129-5p in LSCC.

[Experimental investigation of effects of adenovirus transduced tissue factor pathway inhibitor-2 gene on growth of laryngeal squamous carcinoma].

Objective: To investigate the inhibitory effects of adenovirus transduced TFPI-2 gene on the growth of laryngeal squamous carcinoma.

Methods: Recombinant adenoviruses carrying human TFPI-2 gene were amplified and identified. The nude mouse model of laryngeal squamous carcinoma was established by intracutaneous injection of Hep-2 cells.

[Endostatin in the treatment of the transplantable model of human laryngeal squamous carcinoma in nude mice].

Objective: To evaluate the inhibitory effect of endostatin on tumor growth of human laryngeal squamous carcinoma in nude mice and to explore the possible mechanism of the inhibition and the possible way of biological therapy.

Methods: Nude mice model bearing laryngocarcinoma was established by using human laryngeal squamous carcinoma cell line ( Hep-II). The animals were given endostatin (20 mg x kg(-1) x d(-1)) or PBS, for 21 consecutive days.
