Pseudomyxoma peritonei originating from intestinal duplication: A case report and review of the literature.

Background: Pseudomyxoma peritonei (PMP) is a rare mucinous neoplasm with a relatively low incidence of 1 to 2 per million individuals. It is typically characterized by a type of gelatinous ascites named "jelly belly". Most cases of PMP occur in association with ruptured primary mucinous tumors of the appendix (90%).

[Characteristic of 8p11 Myeloproliferative Syndrome with Rare Phenotype].

Objective: To deeply understand the clinical manifestation, laboratory examination characteristics, diagnosis and treatment of an eight p11 myeloproliferative syndrome (EMS) with rare phenotypes.

Methods: The clinical and laboratory characteristics and the process of allogeneic hematopoietic stem cell transplantation (allo-HSCT) were summarized in 1 rare EMS case involving T/B/myeloid cells. Meanwhile, 2 similar cases in the previous literature were also discussed.

Expression and regulation mechanisms of Sonic Hedgehog in breast cancer.

Sonic Hedgehog (Shh) plays an essential role in vertebrate organogenesis as well as the development of some cancers, including breast cancer. The aim of the present study was to characterize more precisely its role in breast carcinogenesis and elucidate its regulation mechanisms. The expression of Shh was investigated in 97 breast carcinomas and 22 paired non-tumorous tissues (distant from the primary tumor) by immunohistochemistry and in four breast cell lines by Western blotting.

The expression of SIAH1 is downregulated and associated with Bim and apoptosis in human breast cancer tissues and cells.

Seven in absentia homolog1 (SIAH1) was reported as a tumor suppressor and played an important role in regulating cell apoptosis. However, its effects on the breast carcinogenesis remain unclear. In this study, our aims were to examine the relationship between SIAH1 and Bcl-2-interacting mediator of cell death (Bim) and to explore the effects of SIAH1 on the breast carcinogenesis.
