A collection of 57 natural compounds derived from Chinese herbal medicines were evaluated for their an-ti-adipogenic effects. The lipid droplets in differentiated 3T3-L1 adipocytes treated with tested substrate were de-tected by an image-based assay. The results demonstrated that oleanolic acid (OA) inhibited lipid droplets accumula-tion in 3T3-L1 adipocytes in a dose-dependent manner with the IC50 value of 14.5 μmol·L-1. In addition, ToxInsight assay showed that OA was free of liver injury for HepG2 cells within 60 μmol·L-1. It was concluded that OA, which had an obvious anti-adipogenic effect, can be a candidate for hyperlipidemia therapy.

Objective To establish a high-throughput evaluation model for anaphylactic reactions; To screen and identify potential anaphylactogens from TCM monomeric compounds.MethodsCell model of stably expressed MrgX2 was established. Recombinate plasmid pmCherry-C1-MrgX2 was transfected to HEK293 to establish cell line for screening model. MrgX2 agonist and antagonist were used to identify the validation and stability of the cell line. A small library consisting of 180 compounds was profiled by using a cell-based calcium mobilization assay to find novel compounds targeting the MrgX2 receptor. EC50 test, IC50 test, specificity validation and cytotoxicity evaluation were carried out to detect the function of the positive agonist.ResultsThe EC50 of C48/80 to MrgX2 model was 2.7 μg/mL and the IC50 of 2-APB (evoked by 10 μg/mL C48/80) was 46.29 μmol/L. The first generation cell model of MrgX2 was similar to the 20th generation, and the Z factor of MrgX2 cell model was 0.78. In the primary screening for agonist, isoliensinine was identified as a novel agonist targeting receptor MrgX2 with an EC50 of 4.5 μmol/L and IC50 of39.47 μmol/L. Moreover, isoliensinine was validated to activate MrgX2 receptor specifically without cytotoxicity. Conclusion A high-throughput evaluation method for anaphylactic reactions can be established in vitro through calcium mobilization assay. A potential anaphylactogen isoliensinine is identified and validated.

BACKGROUND:
Patients with N2 stage non-small cell lung cancer have prognostic heterogeneity, and this study attempted to explore the prognostic factors among those patients.
METHODS:
Patients with N2 stage undergoing radical resection in Department of Thoracic Surgery, West China hospital, Sichuan University between January 2007 and December 2016 were included. Cox proportional hazard regression model was used to explore the prognostic value of clinicopathological features. Survival curves were plotted by Kaplan-Meier method. Subgroup analyses considering the situation of lymph node involvement were performed.
RESULTS:
In total, 773 patients were included. The median follow-up time was 57.2 months, and the 5-year overall survival rate was 34.8%. Tumor-node-metastasis (TNM) stage, number of involved lymph node stations, skip metastasis, lymphatic or vascular invasion and adjuvant chemotherapy were independent prognostic factors. The patients with stage T1-3 had similar prognosis, while the patients with stage T4 had worse survival. In addition, the patients with single station involvement and skip metastasis had the best prognosis with a 5-years overall survival rate of 48.9%.
CONCLUSIONS
T4 stage patients had worse survival in N2 group. To get a more precisely stratification, skip metastasis and number of involved lymph node stations should be considered in future N stage classification.
