Effect of prophylactic transcatheter arterial chemoembolization on hepatocellular carcinoma with microvascular invasion after R0 resection. A case-control study.

Background: Transcatheter arterial chemoembolization (TACE) is thought to prevent recurrence of hepatocellular carcinoma (HCC), but its efficacy is a matter of controversy.

Objectives: We investigated the effect of preventive TACE on the tumor, nodes, metastasis (TNM) classification in cases of stage II HCC (T2N0M0) after R0 resection.

Design And Setting: Case-control study conducted in a tertiary-level public hospital.

CircRNA_0000502 promotes hepatocellular carcinoma metastasis and inhibits apoptosis through targeting microRNA-124.

Purpose: To investigate the expression level of circ_0000502 in hepatocellular carcinoma (HCC), and to further explore whether it can promote the malignant progression of HCC by targeting and binding to microRNA (miR)-124.

Methods: Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression level of circ_0000502 in 40 pairs of HCC tissue specimens and adjacent ones, and to analyze the relationship between circ_0000502 expression and prognosis of patients with HCC. QRT-PCR was used to verify the expression of circ_0000502 in HCC cells.

Advantages of laparoscopic common bile duct exploration in common bile duct stones.

Objective: To compare the efficacy, safety, and surgical outcomes of laparoscopic common bile duct exploration, endoscopic retrograde cholangiopancreatography, and open common bile duct exploration for treatment of common bile duct stones.

Methods: In total, 210 patients were prospectively randomized into 3 groups: laparoscopic common bile duct exploration, endoscopic retrograde cholangiopancreatography, and open common bile duct exploration. The primary outcome measures were the common bile duct stone clearance rate and the complication rate.

Interaction of Fe-Mn plaque and Arthrobacter echigonensis MN1405 and uptake and translocation of Cd by Phytolacca acinosa Roxb.

In this study, hydroponic experiments were conducted to investigate the role of Fe-Mn plaque and Arthrobacter echigonensis MN1405 under different solution Cd levels (0, 2 and 50 mg L) on Cd uptake and translocation by Phytolacca acinosa Roxb. (P. acinosa).

Growing Slowly 1 locus encodes a PLS-type PPR protein required for RNA editing and plant development in Arabidopsis.

Most pentatricopeptide repeat (PPR) proteins are involved in organelle post-transcriptional processes, including RNA editing. The PPR proteins include the PLS subfamily, containing characteristic triplets of P, L, and S motifs; however, their editing mechanisms and roles in developmental processes are not fully understood. In this study, we isolated the Arabidopsis thaliana Growing slowly 1 (AtGRS1) gene and showed that it functions in RNA editing and plant development.

Phytolacca acinosa Roxb. with Arthrobacter echigonensis MN1405 enhances heavy metal phytoremediation.

The growth and metal-extraction efficiency of plants when exposed to toxic metals can be enhanced by inoculating with certain bacteria, but the mechanisms of this process remain unclear. We report results from glasshouse experiments on the effect of Arthrobacter echigonensis MN1405 in promoting Phytolacca acinosa Roxb. growth when exposed to 100 mg/L Mn solution.

MR diffusion-weighed imaging of rabbit liver.

Aim: To study the techniques of MR diffusion-weighed imaging (DWI) for normal rabbit liver.

Methods: After 15 normal New Zealand white rabbits and one New Zealand white rabbit implanted with VX-2 tumor were anesthetized with 3% soluble pentobarbitone, DWI was performed respectively for different b values, repetition times (TR) or thicknesses, when other parameters were the same and magnetic resonance imaging (MRI) was performed respectively, or with different field of views (FOV) or coil when other parameters were the same. The distinction between groups was analyzed by SPSS10.

MR diffusion-weighted imaging of rabbit liver VX-2 tumor.

Aim: To investigate the implanting method of rabbit liver VX-2 tumor and its MR diffusion-weighted imaging (DWI) characteristics.

Methods: Thirty-five New Zealand rabbits were included in the study. VX-2 tumor was implanted subcutaneously in 14 rabbits and intrahepatically in 6 for pre-experiments.
