Filter by:In this study, the investigators are studying new ways to look for abnormal tissues of the gastrointestinal tract during an endoscopy. We are using a VEGF-A targeting fluorescent probe and a NIR-II fluorescent endoscope to help detect abnormal tissues that are hard to see by the naked eye. The main purposes of this study include: 1. To translate the NIR-II approach into the endoscopy, and understand its advantages and limitations on detecting abnormal tissues in gastrointestinal. 2. To validate whether topical administration of a targeting probe can stick to abnormal tissues and be detected by the NIR-II endoscope. 3. To validate the safety and effectiveness of the topical administration of VEGF-A targeting probes for clinical application.
Clinical trial on acupuncture adjuvant treatment in the pain after the surgery of gastrointestinal carcinoma. Gastrointestinal cancer patients are diagnosed by pathology or cell biology. Patients are randomized into 2 groups: The control group receive normal treatment only, the experimental group receive acupuncture therapy besides normal treatment. Clinical evaluation is based on the observation of the pain degree and life quality improvement. Blood biochemistry tests mainly include Prostaglandin E2(PGE2),5-hydroxytryptamine(5-HT), histamine(HIS), malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), adrenaline, nor-adrenaline, tumor necrosis factor (TNF)-α, cell flow cytometry on Th1, Th2, Th17, Treg cytokines as well as serum cortisol, estradiol (female), progesterone (female), testosterone (male) etc.
The purpose of this study is to determine whether narrowband imaging (NBI) makes it easier for a surgeon to see cancer. NBI is a kind of light. Normally, white light is used during surgery. White light uses many wavelengths of light. NBI only uses two wavelengths which highlight the blood vessels. This makes it easier for the surgeon to see blood vessels. Tumors often have more blood vessels than normal tissue. As a result, NBI may make it easier for the surgeon to see small tumors. In this study the surgeon will look with both normal white light and NBI. This way a comparison can be made to determine which is superior. Improved identification of tumors allows doctors and patients to make informed decisions about whether treatment is needed after surgery. It also provides additional information to determine which treatments may be best.
