The Use of Transperineal Ultrasonography to Compare Relevant Factors for Postpartum Urinary Incontinence Related to Different Modes of Delivery.

Introduction And Hypothesis: Studies concerning the similarities and differences in relevant factors for PPUI in puerpera with delivery modes are scarce. This study aimed to investigate relevant factors for PPUI among primiparas grouped by different delivery modes using transperineal ultrasonography.

Methods: This is a retrospective cohort study.

Synthetic Dibenzoxanthene Derivatives Induce Apoptosis Through Mitochondrial Pathway in Human Hepatocellular Cancer Cells.

A new series of dibenzoxanthenes 4a-4f were synthesized through the nucleophilic substitution and characterized by NMR and MS spectra. Their antitumor activity was screened by MTT assay. Compounds (except 4b and 4c) displayed strong growth inhibitory effects against chosen five tumor cells under light irradiation.
