Role of NLRP3 inflammasome in hepatocellular carcinoma: A double-edged sword.

In recent years, the study of NOD-like receptor thermal protein domain associated protein 3 (NLRP3) inflammasome has become a hot topic, especially its role in various tumors. The incidence of hepatocellular carcinoma is ranked in the top five in China. Hepatocellular carcinoma (HCC) is the predominant and typical form of primary liver cancer.

Intelligent metasurface with frequency recognition for adaptive manipulation of electromagnetic wave.

Due to the strong ability of recognizing electromagnetic (EM) environment and adaptively control of EM waves, the intelligent metasurfaces have received great attention recently. However, the intelligent metasurface with frequency recognition for adaptive manipulation of the EM waves has not been studied. Here, we propose a frequency-recognition intelligent metasurface to precisely control the spatial EM waves under the agile frequencies with the help of a real-time radio-frequency sensor and an adaptive feedback control system.

Use of F-18 FDG PET/CT Through Delayed Diuretic Imaging for Preoperative Evaluation of Upper Urinary Tract-Occupying Lesions.

Purpose: To evaluate the value of F-18 FDG PET/CT in the differentiation of malignant and benign upper urinary tract-occupying lesions.

Patients And Methods: 64 patients with upper urinary tract-occupying lesions underwent F-18 FDG PET/CT at RenJi Hospital from January 2015 to February 2019 in this retrospective study. Of the 64 patients, 50 patients received nephroureterectomy or partial ureterectomy; 14 patients received ureteroscopy and biopsy.

High-Efficiency Spatial-Wave Frequency Multiplication Using Strongly Nonlinear Metasurface.

In the past decades, metasurfaces have opened up a promising venue for manipulating lights and electromagnetic (EM) waves. In the field of nonlinearity, second-harmonic generation (SHG) is a research focus due to its diverse applications. There have been many researches for realizing SHG in optical regime using nonlinear characteristics of optical materials, but its efficiency is low.

Noninvasive Assessment of Portal Hypertension Using Spectral Computed Tomography.

Background: Early diagnosis of portal hypertension is imperative for timely treatment to reduce the mortality rate. However, there is still no adequate method to noninvasively and accurately assess the portal hypertension in routine clinical practice.

Purpose: We aimed to evaluate the accuracy of parameters measured using dual energy spectral computed tomography (LightSpeed CT750 HD) in assessing portal venous pressure in patients with liver cirrhosis.

Expert consensus on image-guided radiofrequency ablation of pulmonary tumors: 2018 edition.

Lung cancer ranks first in incidence and mortality in China. Surgery is the primary method to cure cancer, but only 20-30% of patients are eligible for curative resection. In recent years, in addition to surgery, other local therapies have been developed for patients with numerous localized primary and metastatic pulmonary tumors, including stereotactic body radiation therapy and thermal ablative therapies through percutaneously inserted applicators.

Spectral CT in evaluating the therapeutic effect of transarterial chemoembolization for hepatocellular carcinoma: A retrospective study.

This study aimed to investigate the value of computed tomographic (CT) spectral imaging in evaluating the effect of transarterial chemoembolization (TACE).The records of 67 patients with hepatocellular carcinoma (HCC) who had undergone dynamic spectral CT before treatment were selected for the study. Iodine concentrations pretreatment in liver parenchyma, the HCC lesion(s), portal vein, and aorta were measured from the decomposition images.

The role of liver stiffness measurement in the evaluation of liver function and esophageal varices in cirrhotic patients.

Objective: We aimed to evaluate the efficacy of liver stiffness measurement (LSM) in predicting the presence and severity of esophageal varices (EV) and investigating its association with liver function (LF) in patients with liver cirrhosis.

Methods: Medical records of 90 cirrhotic patients who underwent LSM by transient elastography were retrospectively reviewed. The relationship between LSM and the presence and severity of EV was evaluated by esophagogastroduodenoscopy (EGD) and multislice spiral computed tomography (MSCT).

Study on hippocampal volume with quantitative 3T magnetic resonance imaging in Chinese patients with epilepsy.

Background: It was still rare for the quantitative magnetic resonance imaging (MRI) research of regional changes in hippocampus sclerosis (HS) in Chinese patients with epilepsy. This study aimed to study the hippocampal volumes (HVs) with quantitative MRI measurement in Chinese patients with epilepsy.

Methods: Forty-six Chinese patients with epilepsy (intractable epilepsy (IE), n = 21; non-intractable epilepsy (NIE), n = 25) and 25 normal controls were collected between July 2007 and March 2008.

A diffusion tensor imaging study in essential tremor.

Background And Purpose: Essential tremor (ET) is suggested to be a neural degenerative disease. The authors investigated the fractional anisotropy (FA) and apparent diffusion coefficient (ADC) value in basal ganglia, thalamus, red nucleus, and substantia nigra in ET patients using diffusion tensor image (DTI).

Methods: DTI examination was carried out in patients with ET and controls.
