Rare common bile duct metastasis of breast cancer: A case report and literature review.

Background: Breast cancer is the most common tumor in women, and about one-third of cases develop metastatic disease. However, metastatic breast cancer rarely invades the common bile duct (CBD) directly without involving the liver, and involvement of the gastrointestinal tract is rare. Cases of such metastases pose a particular diagnostic challenge.

CAPS1 promotes colorectal cancer metastasis via Snail mediated epithelial mesenchymal transformation.

Colorectal cancer (CRC) is a common gastrointestinal cancer with high mortality rate mostly due to metastasis. Ca-dependent activator protein for secretion 1 (CAPS1) was originally identified as a soluble factor that reconstitutes Ca-dependent secretion. In this study, we discovered a novel role of CAPS1 in CRC metastasis.

Auphen and dibutyryl cAMP suppress growth of hepatocellular carcinoma by regulating expression of aquaporins 3 and 9 in vivo.

Aim: To investigate whether the regulation of aquaporin 3 (AQP3) and AQP9 induced by Auphen and dibutyryl cAMP (dbcAMP) inhibits hepatic tumorigenesis.

Methods: Expression of AQP3 and AQP9 was detected by Western blot, immunohistochemistry (IHC), and RT-PCR in HCC samples and paired non-cancerous liver tissue samples from 30 hepatocellular carcinoma (HCC) patients. A xenograft tumor model was used in vivo.

[The reason and management of the sunken upper eyelid after hydroxyapatite platform implantation].

Objective: To study the reason and the management of the sunken upper eyelid after implanting a hydroxyapatite platform.

Methods: From 1998, we developed a method of subperiosteal implantation at the orbital floor to repair the introcession of the upper eyelid after hydroxyapatite platform implantation. 11 cases of the sunken upper eyelid were treated with this method.
