The immunotherapy mechanism of Hedyotis Diffusae Herba in treating liver cancer: a study based on network pharmacology, bioinformatics, and experimental validation.

Liver cancer is a malignant tumor that develops on or inside the liver. Hedyotis diffusa Willd (HDW) plays a significant role in anti-tumor activities; however, its mechanism against liver cancer remains unclear. This study aims to evaluate the immunotherapeutic mechanism of HDW in treating liver cancer through network pharmacology, bioinformatics analysis, and experimental validation.

[Application of dynamic contrast enhancement MRI and post-processing technique for diagnosis of breast cancer].

Background And Objective: Magnetic resonance imaging (MRI), an advanced non-invasive technique, is regarded as one of the potential modalities in the diagnosis of breast cancer. This study was to investigate the application of dynamic contrast enhancement MRI and 3D reconstruction images in diagnosing breast tumors.

Methods: From May 2006 to September 2007, 30 patients with breast diseases were scanned with MRI in Sun Yat-sen University Cancer Center.

[Environmental radiation dose monitor after 125I radioactive seed implantation].

Background & Objective: Medical imaging-guided 125I radioactive seed implantation is a new method of mini-invasive therapy. As a component of combined therapy for malignant tumors, 125I implantation has benefits of minimal invasion, accurate position fixing, and certain clinical effects, and has been widely applied to treat tumors at present. Also the environmental phototoxis and radiation protection have been highly regarded.
