Platycodin D (PD) is a triterpene saponin extracted from the root of It has been reported to exhibit multiple pharmacological and biological properties. There is substantial evidence to support that PD displays a wide range of anti-tumor activities. However, the detailed molecular mechanism still needs further elaboration.

This study aims to investigate the needs of child caregivers for popular science about safe medication for children, to deeply explore the characteristics of child caregivers' demand for safe medication and the shortcomings of current popular science work, and then to seek better coping strategies to ensure children's safe medication. A questionnaire was designed based on Lasswell's "5W" communication model to investigate the needs of child caregivers in terms of content, channels, and forms of popular healthcare science on the safe usage of children's medication. The primary ways caregivers receive popular healthcare science education concerning safe medication usage knowledge are through medical institutions, notification by medical staff, and personal media.

Purposes: Microscopic aggressive behaviors may be related with the prognosis of solid pseudopapillary neoplasms (SPNs). In this study, we investigate computed tomography (CT) features and differential diagnosis of aggressive and non-aggressive SPNs in pancreas.

Materials And Methods: 122 patients with pathologically proven SPNs in pancreas were included.

Hypovascular pancreatic neuroendocrine tumors (hypo-PNETs) are often misdiagnosed as pancreatic ductal adenocarcinoma (PDAC). However, the treatment options and prognosis of PNETs and PDAC are substantially different. This retrospective study differentiated hypo-PNETs from PDAC using contrast-enhanced CT (CE-CT).

Background: Imaging findings for pancreatic neuroendocrine carcinoma (PNEC) and pancreatic ductal adenocarcinoma (PDAC) often overlap. The aim of this study was to demonstrate the value of computed tomography (CT) imaging features and texture analysis to differentiate PNEC from PDAC.

Methods: Twenty-eight patients with pathologically-proved PDAC and 14 patients with PNEC were included in this study.

In our efforts of developing novel compounds as potential anticancer agents, a series of tamibarotene analogs containing Zn(2+) -binding moieties were designed and developed. Biological characterization identified compound 7b as the most potent one with improved antiproliferative activities against multiple cancer cell lines, compared to parent compound tamibarotene. Further characterization also demonstrated that compound 7b exhibited moderate activities as a histone deacetylase inhibitor with IC50 of 1.

Temozolomide plays a critical role in curing glioma at present. The purpose of this work was to develop a suitable drug delivery system which could prolong the half-life, improve the brain targeting, and reduce the systemic effect of the drug. Temozolomide-liposomes were formulated by the method of proliposomes.

Tamibarotene (Am80), a poorly water-soluble drug for the treatment of acute promyelocytic leukemia (APL), loaded nanostructured lipid carrier (Am80-NLC) was developed and characterized previously. The purpose of the present work was to develop PEGylated nanostructured lipid carrier (PEG-NLC) for intravenous delivery of Am80, with the aim to further extend the circulation in blood and decrease the adverse events. Am80-loaded PEG-NLC (Am80-PEG-NLC) modified with PEG-40 stearate (PEG40-SA, molecular weight 2000 Da) was formulated by the method of melt-emulsification and low temperature-solidification technique.

Nanosuspensions emerge as a promising strategy for delivery of poorly water-soluble drugs. Albumin is a versatile protein carrier for drug delivery and targeting. The purpose of this study was to develop a formulation of etoposide-loaded bovine serum albumin (BSA) nanosuspensions, to study in vitro characterization, and to estimate the in vivo safety and tissue distribution of etoposide-loaded BSA nanosuspensions for parenteral delivery.

The present work evaluated the feasibility of nanostructured lipid carriers (NLC) for the intravenous delivery of tamibarotene (Am80), a poorly water-soluble drug for the treatment of acute promyelocytic leukemia (APL). The objective of this research was to develop a suitable drug delivery system in vivo which could improve therapeutic efficacy and decrease side effects. The tamibarotene-loaded-NLC (Am80-NLC) nanosuspension was formulated by the method of melt-emulsification at a high temperature and solidified by ice bath.
