Novel 3,4-seco bile acid diamides as selective anticancer proliferation and migration agents.

A series of new seco-A ring bile acid diamides were synthesized, and their antiproliferative activities against PC3M (prostate), HT29 (colon) and ES-2 (ovarian) cancer cell lines were investigated using SRB assays. Most synthesized compounds presented improved antiproliferative activities compared to the parent bile acids (IC50 > 80 μM), especially the piperazine conjugated compound 27 with IC50 values of 1.07, 4.

[Analysis of 574 cases of high-fall death].

Objective: To establish a database of high-fall death cases for future forensic study and practice, based on the scene investigation, injury characteristics and other informations.

Methods: Five hundred and four cases of high-fall death from 5 provinces and cities were included in the study. Data including personal information of the deceased, scene investigation, autopsy findings, history of mental illness and the results of toxicology were collected and analyzed.
