Aim: The purpose of this study was to analyze the relationship between serum indicators and high-throughput drug screening (HDS) results, aiming to achieve specific therapy for hepatocellular carcinoma (HCC).

Methods: This study recruited patients with HCC who underwent surgical resection at the Hepatobiliary Surgery Center of the First Affiliated Hospital of Chongqing Medical University from December 2019 to December 2021. HCC tissues were obtained from patients during surgery and subjected to in vitro cell culture, and then HDS testing was performed on the cultured tissue samples.

Ex-service SF adsorbents in SF gas-insulated electric equipment contain many toxic substances. Inside, HF and HS are two typical toxic gases. Based on the first principle, the interaction process between HF/HS and α-AlO (0001) surfaces was calculated using the density functional theory (DFT).

Objective: The effect of alcohol consumption on the risk of coronary heart disease is controversial. Several studies have assessed the effects of alcohol on the formation of atherosclerotic plaques, but few studies have evaluated the chronic effects of alcohol consumption on the coronary artery diameter. We investigated whether alcohol consumption affects the coronary artery diameter.

Objective: To investigate the effects of metformin (Met) on middle-aged male mice aging induced by D-galactose.

Methods: Fifty nine-month-old male ICR mice were fed in SPF experimental environment and fed freely with water. Subsequently, the mice were randomly divided into 5 groups(n=10): control group, model group, metformin low, medium and high dose groups(Met 50 mg/kg, Met 100 mg/kg, Met 200 mg/kg).

Article Synopsis
  • The study aimed to assess the usefulness of transvaginal 3D power Doppler ultrasound in diagnosing benign versus malignant endometrial diseases among 144 patients with thicker endometrial linings.
  • Key measurements taken included endometrial thickness, volume, and various blood flow indices, with significant differences noted between benign and malignant cases in all these parameters.
  • The findings indicated that transvaginal 3D power Doppler ultrasound is effective for distinguishing between benign and malignant endometrial conditions, highlighting its potential clinical value.

It was reported that α7 nicotinic acetylcholine receptor (α7-nAChR) knockout (α7 KO) mice showed few functional phenotypes. The purpose of this study was to investigate the effect of α7 KO on the electrophysiological characteristics of hippocampus in mice. The effect of α7 KO on hippocampal CA3-CA1 synaptic transmission in mice was evaluated by standard extracellular field potential recordings.

Discrimination between atrioventricular node reentry tachycardia (AVNRT) and orthodromic reciprocating tachycardia (ORT) during an electrophysiological study is sometimes challenging. This study aimed to investigate if the difference in the local VA (ventricle-atrium) interval during ventricular entrainment pacing and during tachycardia (DVA, defined as the shortest local VA interval of coronary sinus [CS] during entrainment minus the shortest local VA interval of CS during tachycardia) was different in patients with AVNRT and patients with ORT.Diagnoses of AVNRT or ORT through a concealed accessory pathway (AP) were made according to conventional electrophysiological criteria and ablation results.

This study was designed to explore differences in the ultrasonographic characteristics of medullary thyroid carcinoma (MTC) and papillary thyroid carcinoma (PTC). This study included 35 cases of MTC and 96 cases of PTC that were surgically and pathologically confirmed. Preoperative ultrasound images were retrospectively reviewed by two physicians (with 5 years' experience in thyroid ultrasound) under the premise of unknown pathological results.

Background: Fenestrations involving aneurysms have been well documented. Only sporadic papers have been reported on fenestrations associated with AVMs (arteriovenous malformations) with few cases. Our study is to determine the rate of co-occurrence of fenestrations and AVMs and to analyze the possible relationship between them by CTA.

Objectives: To analyse the characteristics of basilar artery (BA) fenestrations and their coexistence with aneurysms and other anomalies in a massive cases by computed tomographic angiography (CTA).

Methods: A total of 5,657 sequential cerebral CTA images performed from January 2006 to February 2012 were reviewed. CTA images were obtained from the raw datasets by using volume rendering and maximal intensity projection reconstruction.

Objective: To analyze and compare the performances of two telomere measurement methods (digoxigenin-labeled Southern blot and Real-time PCR) in cellular senescence research.

Methods: Genomic DNA extracted from normal human fibroblasts (2BS) of different population doublings (PDs) was used as test samples. The Southern blot and Real-time PCR methods for telomere measurements were optimized.

Objective: To investigate the impact of expression of kisspeptin-1 (KiSS-1) metastasis-suppressor gene on the proliferative, adhesive and invasive abilities of human hepatocellular carcinoma (HCC) using an in vitro cell system.

Methods: The highly metastatic human hepatoma cell line MHCC97-H was transiently transfected with the pcDNA3.1/HisC vector expressing the KiSS-1 gene (experimental group) or the vector without the KisS-1 gene (blank control group).

Background: It is difficult to ablate a right-sided accessory pathway (AP) with atrial insertion far from the tricuspid annulus (TA). We report our initial experience of ablating this rare AP by a 3-dimensional electroanatomical mapping system (CARTO).

Methods: From January of 2006 to April of 2008, 18 patients with right-sided APs who failed previous outside ablations were enrolled in this study.

Background: Metabolic syndrome (MetS) and atrial fibrillation (AF) are causally related. This study aimed to determine the prevalence of MetS in patients with AF in the absence of structural heart disease from a tertiary hospital in China.

Methods: In a single center, 741 inpatients with AF in the absence of structural heart disease prior to catheter ablation were retrospectively reviewed.

Objective: To detect the expression of survivin protein, survivin mRNA, p27 protein, p27 mRNA and PTEN protein in hepatocellular carcinomas (HCC) and their clinical significances.

Methods: Tissue microarrays were constructed. The expression of survivin protein, p27 protein and PTEN protein were evaluated by immunohistochemical methods and in expression of survivin mRNA and p27 mRNA were evaluated by in stiu hybridization respectively in tumor tissues from 141 HCC patients, 128 samples of para-carcinoma liver tissues, 97 liver tissues far from the carcinomas and normal liver tissues from non HCC patients.

Objective: To evaluate the effect of Yufeining, a traditional Chinese medicine, on induced sputum interleukin-8 (IL-8) in patients with chronic obstructive pulmonary disease (COPD) at the stable phase.

Methods: Thirty-six patients with COPD were divided into trial group (18 cases) and control group (18 cases) randomly. The trial group was treated with Yufeining pills taken orally for half a year; the control group was not given any medicine.
