Construction and validation of a personalized prediction model for postpartum anxiety in pregnant women with preeclampsia.

Background: Preeclampsia is a pregnancy-specific multi-system disease with multi-factor and multi-mechanism characteristics. The cure for preeclampsia is to terminate the pregnancy and deliver the placenta. However, it will reduce the perinatal survival rate, prolong the pregnancy cycle, and increase the incidence of maternal complications.

Detection of point mutations of the Axin1 gene in colorectal cancers.

Axin is a recently identified tumor suppressor that plays an important role in liver and colon cancers. To gain further insights into the structure and function of Axin in controlling cell growth, we analyzed 54 colorectal cancer tissues for mutations in AXIN1 gene. We employed PCR amplification with 23 sets of primers against introns that encompassed the whole coding region of AXIN1 followed by single-strand conformation polymorphism (SSCP) analysis.

[Apoptosis of human gastric cancer cell induced by photochemical riboflavin].

Background & Objective: Photochemical riboflavin, the production of reactive oxygen species (ROS), has been reported having cytotoxity on some cancer cells. The aim of this study was to investigate the effect of photochemical riboflavin on inducing apoptosis in human gastric cancer cell line MGC80-3.

Methods: Trypan blue exclusion method, Giemsa staining, DNA electrophoresis, DNA quantification, Western blot analysis, and flow cytometry were conducted to determine the effect of photochemical riboflavin on cell survival, morphology, DNA fragmentation, gene expression, and cell cycle arresting.
