Colonic tubular duplication combined with congenital megacolon: A case report.

Background: Colonic duplication refers to a spherical or tubular cavity which shows similar properties with the native colon and is attached to the mesenteric side of the alimentary tract. It is the rarest in alimentary tract duplications. Based upon anatomic feature, colonic duplications can be classified as spherical (cystic) or tubular, with the latter being less common (approximately 20%).

Diagnosis and treatment of pure arterial malformation: Three case reports and literature review.

Rationale: The incidence of pure arterial malformations is relatively low, and few cases have been reported. Only 2 cases with pure arterial malformation have been reported to receive surgery or endovascular treatment.

Patient Concerns: We report 3 cases and review the relevant literatures.

Inhibiting the proliferation, migration and invasion of triple negative breast cancer cells through anti-tumor human serum albumin nanoparticles loading aziditaxel as a novel taxane derivative.

Triple negative breast cancer (TNBC) is a severe breast cancer subtype with the high mortality rate, and still is lack of effective therapeutic means so far. Aziditaxel, a water-insoluble compound, is a novel taxane derivative with strong anti-tumor activity. In this study, we constructed an aziditaxel-loaded nano drug delivery system using human serum albumin as a carrier, and further investigated its anti-tumor effect on TNBC in vitro.
