Quality evaluation of Syringae Folium using the five-wavelength fusion fingerprint technique combined with chemometric analysis and quantitative analysis of active constituents.

Syringae Folium (SF) is a traditional Chinese medicine with excellent antibacterial, anti-inflammatory, and antiviral properties. It is widely distributed in northeast China and has three origins. However, the differences between the three origins have never been compared.

Amyloid precursor protein is overexpressed in bladder cancer and contributes to the malignant bladder cancer cell behaviors.

Objectives: To investigate the expression of amyloid precursor protein in bladder cancer, and to study its role in malignant bladder cancer cell behaviors.

Methods: Immunohistochemistry and western blotting analysis were used to detect the amyloid precursor protein level in bladder cancer tissues and cell lines. The effect of amyloid precursor protein on bladder cancer cell proliferation, migration, invasion and cell cycle was evaluated by using small interfering ribonucleic acid.
